Detailed description of the invention
In order to understand the present invention further, below in conjunction with embodiment, the preferred embodiment for the present invention is described, but should be appreciated that these describe just in order to further illustrate the features and advantages of the present invention, instead of limiting to the claimed invention.
First object of the present invention is to provide a kind of positioner processing cylinder cap, the positioning precision not high and easy problem leaving cut on the external surface of cylinder cap when the structural design of the positioner of this processing cylinder cap can solve processing cylinder cap effectively, second object of the present invention is to provide a kind of cylinder cap of engine.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1-2, a kind of positioner processing cylinder cap provided in the embodiment of the present invention, comprising: clamp body 5, and on clamp body 5, be provided with multiple dowel hole and multiple bolt; Be arranged at the pressing plate 3 of the top of clamp body 5, and described pressing plate 3 is supported by the first bolt 4 be arranged on clamp body 5, wherein one end of the first bolt 4 is fixed on clamp body 5, pressing plate 3 supports by the other end, compress by being arranged on clamp body 5 and through the second bolt 2 of pressing plate 3 nut simultaneously, wherein one end of the second bolt 2 is fixed on clamp body 5, and the other end passes pressing plate 3 and utilizes the nut installed to be compressed by pressing plate 3.Wherein the first bolt and the second bolt can be stud, and utilize band shoulder nut to be compressed by pressing plate.
When using the positioner of above-mentioned processing cylinder cap, first the multiple valve-seat bore of precasting when cylinder cap 1 is cast, then multiple alignment pin is utilized to be fixed on clamp body 5 by cylinder cap 1 by the dowel hole in the valve retainer hole on cylinder cap 1 and clamp body 5, now cylinder cap 1 moves up and down because the effect of multiple alignment pin can not carry out left and right, can not rotate.Then, one end of pressing plate 3 is pressed in above cylinder cap 1 or the groove be pressed on cylinder cap 1 sidewall, then utilize the first bolt 4 on clamp body 5 and the second bolt 2 by pressing plate 3 fixed position, pressing plate 3 and clamp body 5 is made tightly to clamp cylinder cap 1, with this, cylinder cap 1 is fixed, make it not move forward and backward.So utilize the positioner of above-mentioned processing cylinder cap that cylinder cap 1 can be made not carry out left and right, up and down and the movement of front and back, reliability is stronger, and cylinder cap 1 is less with the contact area of this positioner, can not leave cut easily in process on the external surface of cylinder cap 1.
In order to optimize technique scheme further, in the positioner of above-mentioned processing cylinder cap, can also arrange pad 6 on the installed surface of the installation cylinder cap 1 of clamp body 5, pad 6 can be utilized like this to adjust the flatness of clamp body 5, its Intermediate gasket 6 can be fixed on clamp body 5 by soket head cap screw.
In addition, in the positioner of above-mentioned processing cylinder cap, holding device can also be comprised, wherein holding device comprises loving mother's seat 7 and threaded rod 9, loving mother's seat 7 can be fixed on clamp body 5 by hex screw, loving mother's seat 7 offers screwed hole, and threaded rod 9 can hold out against through screwed hole the cylinder cap 1 be arranged on clamp body 5, but also loving mother's seat 7 can be utilized to regulate the length of the side of the close cylinder cap 1 of threaded rod 9.Wherein, in order to make threaded rod 9 less with the contact area of cylinder cap 1, the top of threaded rod 9 can be set to spherical structure, the top of threaded rod 9 refers to the one end with the tight cylinder cap 1 of threaded rod 9, the top of threaded rod 9 is set to the plane position that spherical structure not only can hold out against cylinder cap 1 in addition, the reeded position of tool of cylinder cap 1 can also be held out against.In order to the intensity on the top of strengthened thread bar 9, surface hardening process can also be done on the top of threaded rod 9.
In addition, can also the top of threaded rod 9 be arranged bushing, because the stressed effect on the top of threaded rod 9 is comparatively large, easily damage, like this when the top of threaded rod 9 is damaged, only need change bushing, and whole threaded rod 9 need not be changed.
Wherein, in order to convenient rotating threaded rod 9 is to regulate the length of threaded rod 9, can also arrange handle 8 at the end of threaded rod 9, this handle 8 can be arranged perpendicular to threaded rod 9, more time saving and energy saving when adjustment like this.
In order to optimize technique scheme further, in the positioner of above-mentioned processing cylinder cap, in order to make the stressed more symmetrical of the surrounding of cylinder cap 1, in the surrounding of clamp body 5, all holding device can be set, certainly only holding device can also be set on three directions of clamp body 5, in this no limit.
In order to optimize technique scheme further, in the positioner of above-mentioned processing cylinder cap, in order to make the locating effect of alignment pin more reliable, at least one straight flange can be set on the dowel hole of clamp body 5, at the chamfered edge straight pin that the dowel hole utilized with have straight flange matches, cylinder cap 1 is fixed on clamp body 5.Preferably, can the dowel hole that three have straight flange be set on clamp body 5, and in the straight flange of multiple dowel hole, two widths along clamp body 5 are had at least to arrange, remaining length direction along clamp body 5 is arranged, such recycling chamfered edge straight pin positions, make the location of cylinder cap 1 more firm, simultaneously can also in the rectilinear direction of dowel hole, in the side away from straight flange, holding device is set, cylinder cap 1 holds out against by such holding device, and cylinder cap 1 is fixed by chamfered edge straight pin simultaneously, makes location more reliable.
Based on the positioner of the processing cylinder cap provided in above-described embodiment, present invention also offers a kind of cylinder cap of engine.The valve retainer hole of the cylinder cap of engine matches with the dowel hole with straight flange of the positioner of above-mentioned processing cylinder cap, and namely the dowel hole of the valve collar aperture of cylinder cap and the positioner of processing cylinder cap has the straight flange of equal number.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.For device disclosed in embodiment, because it corresponds to the method disclosed in Example, so description is fairly simple, relevant part illustrates see method part.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
