Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-5, the valve body shaft hole processing clamping fixture of the present invention comprises a T-shaped positioning plate 3 assembled with a lathe chuck 1 through a guide rail 2, wherein a planar portion of the T-shaped positioning plate is provided with a rotating body 6 with a T-shaped structure, the rotating body is provided with a cylindrical portion matched with a valve body to be processed and a bottom plate connected with the cylindrical portion, the bottom of the bottom plate is provided with a lower stud 16 rotatably matched and assembled with a circular hole 17 on the planar portion, the planar portion is provided with a rotating body pressing plate 8 for pressing the rotating body 6 on the planar portion to be fixed, and the upper end of the rotating body is fixedly connected with a valve body fixing plate 5 through a bolt 14; the bottom plate and the planar portion of the rotating body 6 are positioned by a positioning pin 7.
And the T-shaped positioning plate is provided with an adjusting long hole on the vertical surface part matched with the lathe disc chuck, and is connected with a universal adjusting bolt 4 of the lathe disc chuck through the adjusting long hole. Therefore, the position of the lathe chuck relative to the lathe for machining can be adjusted to adapt to the position required by machining.
The rotating body pressing plate is connected with the plane portion through a bolt 12, a spring 10 and a top pin 9 are arranged between the plane portion and the rotating pressing plate, and the bolt 12 is sleeved with the spring 10. The ejector pin is hammered into the plane part of the T-shaped positioning plate through interference fit.
Wherein, the locating pin 7 is two, symmetrical arrangement. Thus, the rotating body can be positioned to prevent rotation so as to influence machining.
In the present invention, the guide rail is fixed to the lathe chuck by a screw 11, and a sliding groove is formed on the upper rear surface of the vertical surface portion of the T-shaped positioning plate 3 to allow the T-shaped positioning plate 3 to move to an adjusted position relative to the guide rail, and the T-shaped positioning plate is fixed by an adjusting bolt after the adjusted position.
During the use, when valve body 15 was packed into on the rolling disc, used the valve body fixed plate, compressed tightly the valve body on the rotor through the bolt, after one side shaft hole processing of valve body was finished, loosened the bolt on the valve body fixed plate, extracted the locating pin, rotated the rotor, the knock pin played the supporting pressure plate effect this moment, after the rotor was rotatory 180, with the locating pin location rotor once more to compress tightly through clamp bolt with the clamp plate, process the opposite side shaft hole.
According to the technical scheme, the valve body shaft hole machining mould is convenient to position the corresponding valve body, so that shaft holes on two sides of the valve body can be conveniently machined, and the valve body shaft hole machining mould is simple in structure and convenient to use.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
