Description

Technical Field

[0001] This application relates to the field of shift fork machining technology, and specifically discloses a shift fork drilling fixture. Background Technology

[0002] The shift fork is a core component of the automotive transmission control mechanism. Different transmissions require shift forks with different structures to meet the needs of gear shifting. Figure 1 Taking the shift fork shown as an example, it consists of a main body, a connecting pin located in the middle of one side of the main body, and two fork legs located at the other end of the main body.

[0003] After the shift fork is formed, holes need to be drilled at both ends of the fork legs and the connecting pin. The drilling accuracy of the shift fork is high, and the shift fork needs to be firmly clamped during drilling. However, in the current process of drilling the two ends of the fork legs and the connecting pin, in order to ensure the clamping effect of the shift fork, the fixture usually blocks the drilling position of the fork legs or the drilling position of the connecting pin. This results in the need for multiple clamping and drilling operations of the shift fork, which is complicated and cumbersome. Moreover, the repeated clamping and releasing of the shift fork can easily cause scratches on the surface of the shift fork and affect the quality of the finished product. In view of this, this utility model provides a shift fork drilling fixture to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional shift forks require multiple clamping and drilling processes, which increases the complexity of shift fork production and easily causes scratches on the shift fork surface, affecting the quality of the finished product.

[0005] To achieve the above objectives, the basic solution of this utility model provides a fork drilling fixture, comprising:

[0006] Base plate;

[0007] The fork positioning component is located on the base plate and fits against one end of the fork foot of the shift fork;

[0008] The adjusting seat is symmetrically arranged on the base plate and fits against the other end of the fork foot of the shift fork. The adjusting seat is provided with adjusting bolts that abut against the side wall of the fork foot of the shift fork.

[0009] The first pressure plate is attached to the upper surface of the two forks of the shift fork;

[0010] The second pressure plate is attached to the upper surface of the main body of the first pressure plate and the shift fork, and the second pressure plate is detachably connected to the base plate.

[0011] Furthermore, it also includes:

[0012] A pad, symmetrically placed on the base plate, is used to support the two fork legs of the shift fork;

[0013] A support base, located on the base plate, is the main body of the shift fork.

[0014] Furthermore, the pad includes a connecting part connected to the base and a support part provided on the connecting part, and the support part is provided with a mating surface adapted to the fork foot of the shift fork.

[0015] Furthermore, the fork positioning component includes a plate, positioning blocks respectively disposed at both ends of the plate, and a protrusion disposed at the end of the positioning block, and a positioning groove is formed between the positioning block and the protrusion to accommodate the fork of the fork.

[0016] Furthermore, the positioning block is provided with an inner hole that matches the position of the fork foot drill hole of the shift fork.

[0017] Furthermore, the adjusting seat is L-shaped, with one end located below the fork foot of the shift fork and connected to the base plate, and the other end located on the side of the fork foot of the shift fork and connected to the adjusting bolt.

[0018] The principle and effect of this solution are as follows:

[0019] Compared with the prior art, this utility model can conveniently and quickly clamp the shift fork during the drilling process, and expose the connecting pin and fork legs of the shift fork to the drilling environment. This allows for drilling of both ends of the fork legs and the connecting pin by clamping the shift fork once. This not only simplifies the drilling steps of the shift fork, but also effectively avoids the problem of repeated clamping and releasing of the shift fork, which can easily cause scratches on the surface of the shift fork and affect the quality of the finished product.

[0028] The pads 11 are symmetrically installed on both sides of the base plate 2 by bolts, and are used to support the two fork legs 103 of the shift fork 1 respectively. The pads 11 include a connecting part 1101 connected to the base and a support part 1102 provided on the connecting part 1101. The support part 1102 is provided with a mating surface adapted to the fork legs 103 of the shift fork 1. The support seat 9 is installed on the upper middle part of the base plate 2 by bolts, and is used to support the main body 101 of the shift fork 1.

[0029] The fork-leg positioning component 5 is fixed to the base plate 2 by positioning pins 3 and screws 4. The fork-leg positioning component 5 includes a plate body 501, positioning blocks 502 respectively provided at both ends of the plate body 501, and a protrusion 503 provided at the end of the positioning block 502. A positioning groove is formed between the positioning block 502 and the protrusion 503 to accommodate the fork leg 103 of the shift fork 1. The positioning block 502 is provided with an inner hole 504 that matches the drilling position of the fork leg 103 of the shift fork 1, thereby positioning the end of the fork leg 103 of the shift fork 1 without interfering with the drilling position of the end of the fork leg 103. The adjusting seat 8 is L-shaped. One end of the adjusting seat 8 is located below the fork leg 103 of the shift fork 1 and is connected to the base plate 2 by bolts. The other end of the adjusting seat 8 is located on the top side of the fork leg 103 of the shift fork 1 and is provided with an adjusting bolt 12 that abuts against the side wall of the fork leg 103 of the shift fork 1.

[0030] The two ends of the first pressure plate 7 are respectively attached to the upper surfaces of the two fork legs 103 of the shift fork 1, and the two ends of the second pressure plate 6 are respectively attached to the upper surfaces of the first pressure plate 7 and the main body 101 of the shift fork 1. The second pressure plate 6 is connected and fixed to the base plate 2 by a double-headed screw 10.

[0031] In this embodiment, the fork feet 103 and the main body 101 of the shift fork 1 are supported by the pad 11 and the support base 9, respectively; the position of the shift fork 1 is limited by the cooperation of the fork foot positioning member 5 and the adjusting base 8, and the planar position of the shift fork 1 is locked by the adjusting bolt 12; the shift fork 1 is vertically limited and fixed by the first pressure plate 7 and the second pressure plate 6; and after clamping, the two ends of the fork feet 103 of the shift fork 1 and the two end faces of the part of the connecting pin 102 of the shift fork 1 that need to be drilled are unobstructed, and drilling can be performed directly.

[0032] As can be seen, compared with the prior art, this embodiment can conveniently and quickly clamp the shift fork 1 during the drilling process, and expose the connecting pin 102 and the fork foot 103 of the shift fork 1 to the drilling environment. This allows drilling of both ends of the fork foot 103 and the connecting pin 102 to be performed by clamping the shift fork 1 once. This not only simplifies the drilling steps of the shift fork 1, but also effectively avoids the problem of repeated clamping and releasing of the shift fork 1, which can easily cause scratches on the surface of the shift fork 1 and affect the quality of the finished product.
