本实用新型涉及一种光纤切割装置,其通过使用盘状刀片部件在光纤的玻璃光纤部分的表面上形成切口来切割光纤。The utility model relates to an optical fiber cutting device, which cuts an optical fiber by using a disc-shaped blade part to form an incision on the surface of a glass optical fiber part of the optical fiber.
背景技术 Background technique
“应力断裂”方法是已知的用于切割石英基光纤的方法。The "stress fracture" method is a known method for cleaving silica-based optical fibers.
该应力断裂方法是这样一种方法:首先通过用于形成切口的由超硬合金或金刚石等制成的非常坚硬的切割刀片在光纤的玻璃光纤部分的表面上形成初始切口,随后对玻璃光纤部分施加弯曲应力以便使光纤断裂,即通过裂开从而在光纤的断面上获得镜面。This stress fracture method is a method in which first an initial cut is made on the surface of the glass fiber portion of the optical fiber by a very hard cutting blade made of superhard alloy or diamond etc. for making the cut, and then the glass fiber portion is Bending stress is applied in order to break the fiber, ie by cleaving it so as to obtain a mirror surface on the cross section of the fiber.
根据本方法,可以不使用研磨石等研磨光纤的切割表面而快速地形成镜面。因此,在工地以及实验室,该方法能够有效地连接多种光缆。According to this method, the mirror surface can be quickly formed without using a grinding stone or the like to grind the cut surface of the optical fiber. Therefore, this method can effectively connect various optical cables at the construction site as well as in the laboratory.
已经开发出这样一种装置作为执行这种应力断裂方法的光纤切割装置,该装置构造成将盘状刀片部件朝向光纤的玻璃光纤部分移动,并在该玻璃光纤部分的表面上形成切口。As an optical fiber cleaving apparatus performing this stress fracture method, a device configured to move a disk-shaped blade member toward a glass fiber portion of an optical fiber and form a cut on the surface of the glass fiber portion has been developed.
然而,在这种构造成使用刀片部件在光纤的玻璃光纤部分表面上形成切口的装置中,当重复使用的刀片部件变钝时,通过裂开产生的断裂形成的光纤断面不是良好的镜面。However, in such an apparatus configured to use a blade member to form a cut on the surface of the glass fiber portion of the optical fiber, when the repeatedly used blade member becomes blunt, the fractured section of the optical fiber formed by cleaving is not a good mirror surface.
相应地,提出这样一种光纤切割装置:其中盘状刀片部件安装为在松开用于紧固刀片部件的螺钉时能够自由旋转,并在刀片部件变钝前,装置的操作者松开刀片部件,并使刀片部件围绕其圆盘中心旋转合适的角度,以便改变刀片部件和玻璃光纤部分的接触区域。Accordingly, there has been proposed an optical fiber cutting device in which a disc-shaped blade member is installed so as to be freely rotatable when a screw for fastening the blade member is loosened, and before the blade member becomes blunt, an operator of the device releases the blade member , and rotate the blade part around its disc center at an appropriate angle in order to change the contact area between the blade part and the glass optical fiber part.
然而,该相关技术的装置存在下述的问题。即,旋转刀片部件来改变刀片部件和玻璃光纤部分之间接触区域的操作使得操作者承受的负担较重。此外,改变刀片部件和玻璃光纤部分之间接触区域的频率随着操作者而改变。因此,难以适当地改变刀片部件与玻璃光纤部分之间的接触区域。However, the device of this related art has the following problems. That is, the operation of rotating the blade member to change the contact area between the blade member and the glass optical fiber portion imposes a heavy burden on the operator. Furthermore, the frequency of changing the contact area between the blade member and the glass fiber portion varies with the operator. Therefore, it is difficult to appropriately change the contact area between the blade member and the glass optical fiber portion.
相应地,为了避免出现这种问题,提出了如图13A和图13B所示的光纤切割装置。Accordingly, in order to avoid such a problem, an optical fiber cutting device as shown in FIGS. 13A and 13B has been proposed.
在未审查的日本专利公开No.6-186436中公开了光纤切割装置100。光纤切割装置100具有一对上、下夹紧部件104和105,盘状刀片部件107,支撑框架109和块部件111。上夹紧部件104和下夹紧部件105保持通过剥离光纤102的包层而露出的玻璃光纤部分103。盘状刀片部件107适于移动到由这些夹紧部件104和105固定的玻璃光纤部分103的下方,并在玻璃光纤部分103的外周面上形成切口。支撑框架109以可旋转的方式支撑刀片部件107。块部件111以可上下移动的方式设置在玻璃光纤部分103的上方,以便将弯曲负载施加到玻璃光纤部分103的上表面。在完成使用刀片部件107在由夹紧部件104和105固定的玻璃光纤部分103上形成切口的操作之后,通过块部件111对玻璃光纤部分103施加弯曲负载。由此获得由光纤裂开而形成的断面。The optical
如图13B所示,在光纤切割装置100中,齿轮113一体地设置在刀片部件107的侧面上。齿轮113与驱动齿轮的第一板簧115以及用于防止齿轮反向旋转的第二板簧117啮合。As shown in FIG. 13B , in the optical
当块部件111落下时,第一板簧115由操作销119向下推压,该操作销119固定地设置在块部件111的基端。齿轮113沿着如图13B所示的箭头方向R旋转预定恒定角度。由于齿轮113与刀片部件107是一体的,因此刀片部件107与齿轮113一体地旋转预定恒定角度。因此,改变了刀片部件107与玻璃光纤部分103的接触区域。When the
即,在图13A和图13B所示的光纤切割装置100中,刀片部件107与块部件111的下降运动同步地自动旋转预定恒定角度,以便使其上形成有切口的玻璃光纤部分103裂开。这样,改变了刀片部件107与玻璃光纤部分103的接触区域。相应地,可以改变刀片部件的接触区域而不增加操作者的负担。此外,可以减小接触区域改变频率的变化。That is, in the optical
同时,在光纤切割装置100中,通过每次将刀片部件107旋转对应于例如圆周的(1/12)的预定角度来改变刀片部件107与玻璃光纤部分103的接触区域。然而,考虑到用于旋转刀片部件107的齿轮113的可加工性以及制造成本,刀片部件107每次旋转的预定恒定角度存在下限。Meanwhile, in the optical
因此,在相关技术的光纤切割装置100中,接触区域每次改变的长度相对较长。相应地,改变刀片部件107的接触区域的次数存在限制。因此,相关技术的光纤切割装置100存在难以延长刀片部件107的寿命的问题。Therefore, in the optical

The amount of rotation to rotate the blade member is set to an optionally smaller value, thereby prolonging the life of the blade member.
通过具有下述构造的装置实现本实用新型。The utility model is realized by a device having the following configuration.
(1)、一种用于切割光纤的光纤切割装置,包括:盘状刀片部件,通过将所述刀片部件移向所述光纤的玻璃光纤部分,所述刀片部件在所述光纤的玻璃光纤部分的表面上形成切口。所述光纤切割装置的特征在于,通过使所述刀片部件与其移动操作同步地旋转,以改变所述刀片部件和所述玻璃光纤部分之间的接触区域。(1), an optical fiber cutting device for cutting an optical fiber, comprising: a disc-shaped blade part, by moving the blade part toward the glass fiber part of the optical fiber, the blade part is positioned at the glass fiber part of the optical fiber cuts on the surface. The optical fiber cutting device is characterized in that the contact area between the blade member and the glass optical fiber portion is changed by rotating the blade member in synchronization with its moving operation.
采用该构造,所述刀片部件与其移动同步地旋转。所述刀片部件与所述玻璃光纤部分之间的接触区域自动地改变。With this configuration, the blade member rotates in synchronization with its movement. The contact area between the blade part and the glass optical fiber part is automatically changed.
相应地,可以自动地改变所述刀片部件与所述玻璃光纤部分之间的接触区域而不增加操作者的负担。Accordingly, it is possible to automatically change the contact area between the blade member and the glass optical fiber portion without increasing the burden on the operator.
(2)、(1)中所述的光纤切割装置的实施例(下面称为(2)中所述的光纤切割装置)还包括:接触部件,其固定地设置在所述刀片部件的移动路径中。所述光纤切割装置的特征在于,通过所述刀片部件和所述接触部件之间的接触产生的接触摩擦力实现所述刀片部件的旋转。(2), the embodiment of the optical fiber cutting device described in (1) (hereinafter referred to as the optical fiber cutting device described in (2)) also includes: a contact part, which is fixedly arranged on the moving path of the blade part middle. The optical fiber cutting device is characterized in that the blade member is rotated by contact friction force generated by contact between the blade member and the contact member.

这样,在所述刀片部件的移动操作中,所述接触部件在去程和返程上与所述送入辊接触。然而,由于设置了单向离合器,所述刀片部件仅在去程和返程中之一上旋转。因此,即使在去程上作用在所述接触部件和所述送入辊之间的接触摩擦力的方向与返程上的接触摩擦力方向相反,也不会使所述刀片部件反向旋转。因此,可以适当地沿一个方向旋转所述刀片部件。Thus, in the moving operation of the blade member, the contact member is in contact with the feed-in roller in the forward and return strokes. However, due to the provision of the one-way clutch, the blade member rotates only on one of the forward and return strokes. Therefore, even if the direction of the contact friction force acting between the contact member and the feeding roller on the forward stroke is opposite to the direction of the contact friction force on the return stroke, the blade member is not reversely rotated. Therefore, the blade member can be properly rotated in one direction.
此外,根据所述单向离合器的操作方向的选择,可以确定所述刀片部件是在去程上旋转还是在返程上旋转。Furthermore, depending on the selection of the operating direction of the one-way clutch, it may be determined whether the blade member rotates on the forward stroke or on the return stroke.

The optical fiber cutting device is characterized in that the contact member is fixed by the position adjustment mechanism, and the rotation amount of the blade member is changed by adjusting the position adjustment mechanism.
采用这样的构造,通过使用所述位置调节机构调节接触摩擦,可以将用于改变所述接触区域的所述刀片部件的旋转量设定为任意值。因此,可以增大所述刀片部件的接触区域的最大改变次数。相应地,可以延长所述刀片部件的寿命。With such a configuration, by adjusting the contact friction using the position adjustment mechanism, the rotation amount of the blade member for changing the contact area can be set to an arbitrary value. Therefore, the maximum number of changes of the contact area of the blade part can be increased. Accordingly, the life of the blade part can be extended.

In addition, by adjusting the position of the contact member in the moving direction of the blade member perpendicular to the rotation axis of the blade member, the contact length between the contact member and the feeding roller can be adjusted to any value. By adjusting the position of the contact member in a direction perpendicular to both the rotation axis direction of the blade member and the moving direction of the blade member, the contact pressure between the contact member and the feeding roller can be adjusted. to any value.

具体实施方式 Detailed ways
下面,参照附图详细描述根据本实用新型的光纤切割装置的优选实施例。Hereinafter, preferred embodiments of the optical fiber cutting device according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a plan view showing a body of the optical fiber cutting device shown in FIG. 1 . FIG. 3 is a view taken along the direction of arrow A shown in FIG. 2 . 4A to 4D are explanatory diagrams showing an operation of forming a cut in a glass optical fiber portion using the blade member shown in FIG. 3 .
如图1所示,光纤切割装置1包括:下壳5,其具有盘状刀片部件3;以及上壳9,其通过铰链部件7以可旋转的方式连接到下壳5的一端。As shown in FIG. 1 , the optical
如图1所示,用于定位光纤保持器17的光纤安装部分19设置在下壳5的上表面上,光纤保持器17用于保持光纤15。As shown in FIG. 1 , an optical
光纤保持器17具有用于从下方支撑光纤保持器17的基座21以及用于将光纤15压在基座21上的压板22。The fiber holder 17 has a base 21 for supporting the fiber holder 17 from below and a
光纤安装部分19进行光纤保持器17的定位,从而使得从光纤保持器17保持的光纤15的端部露出的玻璃光纤部分16在下壳5上方与刀片部件3的移动路径(即由图2所示的箭头X表示的路径)交叉。The optical
以可以沿着图2所示的箭头X表示的方向移动的方式支撑支撑框架11,该支撑框架11以可旋转的方式支撑盘状刀片部件3。如图4A所示,当支撑框架11从下壳5的侧面露出的端面11a受到推压时,该支撑框架11沿着推压端面11a的方向滑动。刀片部件3与支撑框架11一体地移动。A supporting
如图4A到图4D所示,弹簧部件13设置在支撑框架11的相对侧,并用于沿着将支撑框架11推回的方向推压支撑框架11。As shown in FIGS. 4A to 4D ,
如图4B所示,当推压并滑动支撑框架11使得刀片部件3超过切口形成位置P(即如下所述,刀片部件3与光纤中的玻璃光纤部分16接触并形成切口的位置)时,支撑框架11与设置在下壳5中的挂止机构(未示出)接合并固定在该位置。As shown in FIG. 4B, when the
如图4B所示,在刀片部件3超过切口形成位置P并固定之后,如图4C所示,将保持光纤15的光纤保持器17设定在光纤安装部分19上。由此,将玻璃光纤部分16定位在切口形成位置P处。As shown in FIG. 4B , after the
当处于图4C所示的位置时,上壳9是关闭的(即,将上壳9转向下壳5并压在下壳5的上表面上),设置在上壳9上的接合解除件(未示出)解除支撑框架11和挂止机构之间的接合。因此,弹簧部件13的推压力使支撑框架11快速返回到初始位置。此时刀片部件3的移动操作使得刀片部件3的切割刀刃与玻璃光纤部分16接触,并在玻璃光纤部分16上形成切口。When in the position shown in Figure 4C, the
在根据本实用新型的光纤切割装置1中,与刀片部件3的用于形成切口的移动操作同步地旋转刀片部件3。由此改变刀片部件3与玻璃光纤部分16的接触区域。In the optical
用于使刀片部件3与其移动操作同步地旋转的机构构造如下。The mechanism for rotating the
在刀片部件3的用于形成切口的移动操作中,通过刀片部件3和接触部件27之间的接触所产生的接触摩擦力实现刀片部件3与其移动同步地旋转,接触部件27固定地设置在刀片部件3的移动路径中。In the moving operation of the
接触部件27由摩擦系数大的橡胶材料制成,并通过位置调节机构28固定到下壳5的本体上,位置调节机构28设置在刀片部件3的移动路径中。The
如图2和图3所示,刀片部件3包括:送入辊31,其构造成通过与接触部件27接触并接受接触摩擦力而旋转;以及单向离合器33,其构造成仅当送入辊31沿着特定方向旋转时将送入辊31的扭矩传递到刀片部件3,从而使得刀片部件3旋转。As shown in FIGS. 2 and 3 , the
在本实施例中,单向离合器33嵌入送入辊31的内周部分。单向离合器33的输出轴固定到刀片部件3的中心轴上。In the present embodiment, the one-way clutch 33 is fitted into the inner peripheral portion of the feed-in
位置调节机构28是板部件,接触部件27固定到该板部件的上表面上。位置调节机构28安装到下壳5的本体上并能够实现三个方向上的位置调节,这三个方向包括:盘状刀片部件3的旋转轴线的方向(即图2中所示的Y方向)、与刀片部件3的旋转轴线垂直的刀片部件3的移动方向(即图2中所示的X方向)、以及与刀片部件3的旋转轴线和刀片部件3的移动方向都垂直的方向。通过使位置调节机构28进行三个方向(即X方向、Y方向和Z方向)上的位置调节,可以调节接触部件27与送入辊31接触的位置在每个方向上的位置。The
通过调节接触部件27与送入辊31接触的位置,可以改变送入辊31和接触部件27之间的接触面积以及作用在两者之间的接触压力。因此,可以调节送入辊31和接触部件27之间的接触摩擦力的大小。By adjusting the position where the
在本实施例中,如图4A到图4D所示,接触部件27的设置位置设定为沿着刀片部件3移动的方向与切口形成位置相隔预定距离。因此,在推压支撑框架11使送入辊31通过切口形成位置P后,在偏离切口形成位置P的位置处,使刀片部件3由于接触部件27和刀片部件3之间的接触摩擦而旋转。In this embodiment, as shown in FIGS. 4A to 4D , the
然后,在根据本实施例的光纤切割装置1中,如图4D所示,在刀片部件3移动返回的路径中设置与刀片部件3接触的清洁装置35,用于清洁刀片部件3的表面。Then, in the optical
清洁装置35安装在上壳9中。当上壳9关闭时,清洁装置35突出到刀片部件3的移动路径中。此外,通过刀片部件3和清洁装置35的刷毛(或非织造布)之间的接触清扫刀片部件3的表面。The
在上述光纤切割装置1中,与用于在玻璃光纤部分16上形成切口24的刀片部件3的移动操作同步地使刀片部件3旋转。这样,刀片部件3和玻璃光纤部分16之间的接触区域自动地改变。In the optical
因此,可以自动地改变刀片部件3和玻璃光纤部分16之间的接触区域,而不增加操作者的负担。Therefore, it is possible to automatically change the contact area between the
此外,在根据本实施例的光纤切割装置1中,通过接触摩擦力实现刀片部件3的旋转,上述接触摩擦力通过刀片部件3和固定地设置在刀片部件3的移动路径中的接触部件27之间的接触产生。Furthermore, in the optical
刀片部件3包括:送入辊31,其用于接受接触摩擦力;以及单向离合器33,其用于仅当送入辊31沿一个方向旋转时将送入辊31的扭矩传递到刀片部件3。The
这样,在用于在玻璃光纤部分16上形成切口24的刀片部件3的移动操作中,接触部件27在去程和返程上与送入辊31接触。然而,由于设置了单向离合器33,刀片部件3仅能在去程和返程之一上旋转。因此,即使在去程上作用在接触部件27和送入辊31之间的接触摩擦力的方向与返程上的接触摩擦力的方向相反,也不会使刀片部件3反向旋转。因此,刀片部件3可以适当地沿一个方向旋转。Thus, in the moving operation of the
此外,根据单向离合器33的操作方向的选择,可以确定刀片部件3是在去程旋转还是在返程上旋转。Furthermore, depending on the selection of the operating direction of the one-way clutch 33, it can be determined whether the
在上述实施例中,刀片部件3在去程上旋转。因此,确保刀片部件3由于接触部件27和送入辊31之间的接触摩擦力而旋转。然而,可以调整刀片部件3,使得当刀片部件3由于弹簧部件13的推力而在返程上返回移动时旋转。采用这样的构造,为了在送入辊31由于弹簧的推力而快速返回移动时能可靠地获得接触摩擦力,优选的是,接触部件27通过板簧等对送入辊31施加弹力。In the above-described embodiments, the
此外,在根据本实施例的光纤切割装置1中,通过位置调节机构28将接触部件27固定在刀片部件3的移动路径中,位置调节机构28用于调节接触部件27和送入辊31之间的接触摩擦力。通过使用位置调节机构28将接触摩擦力的大小调节到较小值来将刀片部件3的旋转量调节到较小量。In addition, in the optical
因此,可以增大刀片部件3的接触区域的最大改变次数。相应地,可以延长刀片部件3的寿命。Therefore, the maximum number of changes of the contact area of the
此外,根据本实施例的光纤切割装置1,位置调节机构28能够调节接触部件27在三个方向上的位置,这三个方向包括:刀片部件3的旋转轴线的方向(即图2中所示的Y方向)、与刀片部件3的旋转轴线方向垂直的刀片部件3的移动方向(即图2中所示的X方向)、以及与刀片部件3的旋转轴线和刀片部件3的移动方向都垂直的方向(即图3中的Z方向)。In addition, according to the optical
这样,通过沿着刀片部件3的旋转轴线的方向调节接触部件27的位置,可以将接触部件27和送入辊31之间的接触宽度调节为任意值。此外,通过沿着与刀片部件3的旋转轴线垂直的刀片部件3的移动方向调整接触部件27的位置,可以将接触部件27和送入辊31之间的接触长度调节为任意值。通过沿着与刀片部件3的旋转轴线方向和刀片部件3的移动方向都垂直的方向调整接触部件27的位置,可以将接触部件27和送入辊31之间的接触压力调节为任意值。通过位置调节机构28进行分别对应于这三个方向的调节的组合可以增大接触部件27和送入辊31之间的接触摩擦力的调节范围,并且可以对接触摩擦力进行微调。例如,用于改变刀片部件3的接触区域的刀片部件3的旋转量设定为最小值,以便延长刀片部件3的使用寿命。此外,可以恢复由于接触部件27的摩损而减小的接触摩擦力。In this way, by adjusting the position of the
顺便提及,考虑到刀片与玻璃光纤部分16接触的长度和刀片部件3的寿命,可取的是,将每次改变刀片部件3的接触区域时刀片部件3的旋转量设定为5度到35度的范围内的适当值。这样,在每次改变刀片部件3的接触区域时刀片部件3的旋转量受到限制的情况下,每次改变的接触区域的长度不会过大。因此,接触区域需要改变的次数在10到72的范围内。因此,可以通过刀片部件的旋转来改变接触区域,从而可靠地延长刀片部件的寿命。Incidentally, considering the length of the blade contacting the glass
更具体地说,在将每次改变时刀片部件的旋转量设定为15度的情况下,可以将接触区域改变24次。结果,可以延长刀片部件3的寿命,同时保持刀片部件3非常锋利。More specifically, in the case where the amount of rotation of the blade member per change is set to 15 degrees, the contact area can be changed 24 times. As a result, the life of the
此外,在根据本实施例的光纤切割装置1中,可以在偏离切口形成位置P的位置处使刀片部件3由于接触部件27和刀片部件3之间的接触摩擦力而旋转。Furthermore, in the optical
这样,在刀片部件3静止的状态下使刀片部件3和玻璃光纤部分16在切口形成位置P接触。因此,可以高精度地形成切口。此外,可以减小刀片部件3的损伤。In this way, the
此外,在根据本实施例的光纤切割装置1中,如图4D所示,在刀片部件3的移动路径中设置有与刀片部件3接触的清洁装置35,用于清洁刀片部件3的表面。In addition, in the optical
相应地,即使在玻璃光纤部分16上形成切口时产生的碎屑附着在刀片部件3上,也可以在下一次切口形成操作之前通过清洁装置35的清洁操作移除附着在刀片部件3上的碎屑。因此,残留在刀片部件3上的碎屑不会影响下一次切口形成操作。Accordingly, even if debris adhering to the
接下来,描述根据本实用新型的光纤切割装置的第二实施例。图5是示出根据本实用新型的光纤切割装置的第二实施例的本体的平面图。图6是沿着图5所示的箭头B的方向得到的视图。Next, the second embodiment of the optical fiber cutting device according to the present invention will be described. Fig. 5 is a plan view showing the body of the second embodiment of the optical fiber cutting device according to the present invention. FIG. 6 is a view taken along the direction of arrow B shown in FIG. 5 .
除了用于与刀片部件3的移动同步地旋转刀片部件3的机构以外,根据第二实施例的光纤切割装置1A与第一实施例相似。相同的附图标记表示与第一实施例相同的部件和位置。因而省略对相同部件和位置的描述。An optical fiber cutting device 1A according to the second embodiment is similar to the first embodiment except for a mechanism for rotating the
根据第二实施例,使用齿轮37以及臂部件39实现刀片部件3与其移动同步地旋转,齿轮37与刀片部件3一体地设置,臂部件39固定地设置在刀片3的移动路径中以便与齿轮37表面接触。According to the second embodiment, the rotation of the
齿轮37构造成在环状外周表面上沿着圆周方向连续地形成凹齿和凸齿。通过将从齿轮37的朝向刀片部件3的表面突出的突出部(未示出)配合到形成在刀片部件3的相关表面中的孔,以使齿轮37与刀片部件3形成一体。The
通过穿过刀片部件3中心的螺钉43将与齿轮37一体形成的刀片部件3以可旋转的方式安装到支撑框架11中。盘簧45设置在齿轮37和螺钉43之间。通过盘簧45的推力将刀片部件3推压在支撑框架11上,从而将刀片部件3安装在支撑框架11中,推力在1kgf到3kgf的范围内。通过该推力确保刀片部件3的安装精度。然而,在过紧地紧固螺钉43而使推力变得过大时,刀片部件3不容易旋转。相反,在过松地紧固螺钉43的情况下,刀片部件3容易旋转。因此,推力的大小规定在上述1kgf到3kgf的范围内。The
臂部件39设置在位置调节机构28上,从而使得臂部件39的一端以可摆动的方式安装在位置调节机构28上,而臂部件39的另一端被支撑为可以沿接近或离开位置调节机构28的方向摆动。The
设置在臂部件39和位置调节机构28之间的压缩弹簧47以78gf到100gf的弹簧力推压臂部件39,从而使得臂部件39可以与齿轮37弹性接触。The
此时,压缩弹簧47的推力大小设定为满足如下条件,即:在刀片部件3的移动操作的去程上,齿轮37通过与臂部件39接触而旋转,在旋转过程中,当已旋转的齿轮37的齿(凸齿和凹齿)41的顶部与臂部件39接触并最大程度地压下臂部件39(即,压缩弹簧47最大程度地压缩)时,阻止齿轮37的旋转。此外,当刀片部件3在其返程上移动时,保持齿轮37不旋转的状态。因此,通过刀片部件3的接触区域在玻璃光纤部分上形成切口,当刀片部件3在其去程上移动时上述接触区域已经改变。顺便提及,仅仅通过压缩弹簧47的推力不能可靠地阻止齿轮37的旋转。相应地,可取的是,通过同时调整刀片部件3推压在支撑框架11上的推力来控制齿轮37的旋转。At this time, the magnitude of the thrust of the
顺便提及,可以通过改变齿轮37的齿41的节距而根据齿轮37来改变刀片部件3的旋转量。可选的是,可以通过将单个齿轮37的齿41的节距设定为非均匀地改变,以改变刀片部件3的旋转量。Incidentally, the rotation amount of the
与第一实施例相似,在这种情况下,将每次改变刀片部件3的接触区域时刀片部件3的旋转量设定为5度到35度的范围内的适当值。这样,每次改变的接触区域的长度不会过大。因此,可以将刀片部件的接触区域的最大改变次数设定为足够大的数值。相应地,延长了刀片部件的寿命。Similar to the first embodiment, in this case, the rotation amount of the
在上述光纤切割装置1A中,通过省略在第一实施例中使用的单向离合器,可以实现装置结构的简化和制造成本的降低。In the above-mentioned optical fiber cutting device 1A, by omitting the one-way clutch used in the first embodiment, the simplification of the device structure and the reduction of the manufacturing cost can be achieved.
此外,在根据第二实施例的光纤切割装置1A中,可以通过齿轮37和臂部件39之间的接触或弹性接触实现刀片部件3的旋转,齿轮37与刀片部件3一体地形成,臂部件39固定地设置在刀片部件3的移动路径中。因此,可以可靠地旋转刀片部件3。Furthermore, in the optical fiber cutting device 1A according to the second embodiment, the rotation of the
此外,在上述两个实施例中,刀片部件3在移动的去程上旋转。然后,当刀片部件3在返程上移动时,通过刀片部件3的改变的接触区域在玻璃光纤部分的表面上形成切口。这样,在每次即将进行在玻璃光纤部分的表面上形成切口的操作之前,改变刀片部件3的接触区域。因此,可以通过边缘锋利的刀片部件形成切口。Furthermore, in the two embodiments described above, the
顺便提及,在第二实施例中描述的用于将齿轮37固定到刀片部件3上的具体结构不限于第二实施例所描述的结构。Incidentally, the specific structure for fixing the
在下文中,依次描述通过改进在第二实施例中描述的用于将齿轮37固定到刀片部件3上的具体结构而获得第三实施例到第五实施例。Hereinafter, the third to fifth embodiments obtained by modifying the specific structure for fixing the

根据第三实施例的光纤切割装置1B是在第二实施例中描述的用于将齿轮37固定到刀片部件3上的结构的改进。第三实施例的其它部件与第二实施例的对应部件相同。相同附图标记表示相同部件和位置。因而省略对相同部件和位置的描述。The optical
在第三实施例中,在刀片部件3的表面的平坦部分设置有:圆形沉孔51,其中配合齿轮37以便对齿轮37进行定位;以及旋转停止销53,其从沉孔51的底面朝向齿轮37突出。圆形沉孔51阻止配合到其中的齿轮37沿着垂直于齿轮37的中心轴线的方向移动。In the third embodiment, the flat portion of the surface of the
如图8所示,旋转停止销53嵌入配合到沉孔51中的齿轮37的齿41之间,从而限制配合在沉孔51中的齿轮37的旋转。As shown in FIG. 8 , the
在齿轮37和沉孔51之间的接触表面施加有粘接剂。An adhesive is applied to the contact surface between the
也就是说,在第三实施例中,通过粘接剂的粘结强度、由沉孔51产生的用于限制齿轮37沿垂直于齿轮37中心轴线的方向的位置的力、以及旋转停止销53与齿41的接合产生的阻止齿轮37旋转的效应,齿轮37固定到刀片部件3上并与其成为一体。That is, in the third embodiment, by the bonding strength of the adhesive, the force for restricting the position of the

通过进一步改进在第三实施例中描述的用于将齿轮37固定到刀片部件3上的结构获得根据第四实施例的光纤切割装置1C。第四实施例的其它部件与第二实施例和第三实施例的对应部件相同。相同附图标记表示相同部件和位置。因而省略对相同部件和位置的描述。The optical fiber cutting device 1C according to the fourth embodiment is obtained by further improving the structure for fixing the
在第四实施例中,在刀片部件3的表面的平坦部分设置有:圆形沉孔51,其中配合齿轮37以便对齿轮37进行定位;以及旋转停止销54,其从沉孔51的底面朝向齿轮37突出。圆形沉孔51阻止配合到其中的齿轮37沿着垂直于齿轮37的中心轴线的方向移动。In the fourth embodiment, the flat part of the surface of the
如图9和图10所示,齿轮37配合在沉孔51中,旋转停止销54配合在设置于齿轮37上的接合孔55中,从而限制配合在沉孔51中的齿轮37的旋转。As shown in FIGS. 9 and 10 , the
在齿轮37和沉孔51之间的接触表面施加有粘接剂。An adhesive is applied to the contact surface between the
也就是说,在第四实施例中,通过粘接剂的粘结强度、由沉孔51产生的用于限制齿轮37沿垂直于齿轮37的中心轴线的方向的位置的力、以及旋转停止销54与接合孔55的接合产生的阻止齿轮37旋转的效应,齿轮37固定到刀片部件3上并与其成为一体。That is, in the fourth embodiment, by the bonding strength of the adhesive, the force for restricting the position of the
图11是示出根据本实用新型的光纤切割装置的第五实施例的本体的主要部分的平面图。图12是沿着图11所示的箭头E的方向得到的视图。Fig. 11 is a plan view showing main parts of a body of a fifth embodiment of an optical fiber cutting device according to the present invention. FIG. 12 is a view taken along the direction of arrow E shown in FIG. 11 .
通过进一步改进在第三实施例中描述的用于将齿轮37固定到刀片部件3上的结构获得根据第五实施例的光纤切割装置1D。第五实施例的其它部件与第二实施例和第三实施例的对应部件相同。相同附图标记表示相同部件和位置。因而省略对相同部件和位置的描述。The optical fiber cutting device 1D according to the fifth embodiment is obtained by further improving the structure for fixing the
在第五实施例中,在刀片部件3的表面的平坦部分设置有:圆形沉孔51,其中配合齿轮37以便对齿轮37进行定位;以及螺钉插孔56,其形成在沉孔51中并从刀片部件3的背面侧穿透刀片部件3。圆形沉孔51阻止配合到其中的齿轮37沿着垂直于齿轮37的中心轴线的方向移动。In the fifth embodiment, the flat portion of the surface of the
螺钉57从刀片部件3的背面侧穿过螺钉插孔56。螺钉57旋入穿透齿轮37的内螺纹部分58。这样,限制了配合到沉孔51中的齿轮37的旋转。A
也就是说,在第五实施例中,通过沉孔51产生的用于限制齿轮37沿垂直于齿轮37的中心轴线的方向的位置的力、以及将螺钉57旋入内螺纹部分58的效应,齿轮37固定到刀片部件3上并与其成为一体。That is, in the fifth embodiment, the force for limiting the position of the
在第五实施例中,通过螺钉57的紧固力,齿轮37可以紧密地安装到沉孔51的底面上。这样,省略了使用粘接剂进行强化。In the fifth embodiment, the
此外,如图12所示,在第五实施例中,沿着刀片部件3的圆周方向间隔开的多个位置上设置有能够对刀片部件3的旋转状态进行视觉检验的标记61。Furthermore, as shown in FIG. 12 , in the fifth embodiment, marks 61 enabling visual inspection of the rotational state of the
在如图12所示的实例中,沿着圆周方向均匀间隔(即在圆周上以45度间隔)的8个位置上设置标记61。然而,标记61之间的间隔不限于此。可取的是,将间隔设定为例如从20度到45度的范围内的适当值。In the example shown in FIG. 12 , marks 61 are provided at 8 positions that are evenly spaced along the circumferential direction (that is, at intervals of 45 degrees on the circumference). However, the interval between the marks 61 is not limited thereto. It is desirable to set the interval to an appropriate value within a range from, for example, 20 degrees to 45 degrees.
采用设置有标记61的构造,在刀片部件3与其移动操作同步地旋转时,设置在刀片部件3上的标记61相对于设置在下壳5(参见图1)中的基准点(未示出)移动。这样,操作者可以容易地视觉检验是否通过刀片部件3的旋转适当地改变了刀片部件3的接触区域。这便于执行调节刀片部件3的旋转量的操作,该旋转与其移动操作同步。此外,例如,可以在刀片部件3上刻制以升序或降序排列的各自表示数值的数字符号,以代替如图12所示的三角标记。因此,可以清楚地示出刀片部件3的使用量或剩余量。With the configuration provided with the mark 61, when the
