[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model provides, for example Figure 1-5 The fixture shown includes a fixture base 1 and a main body for clamping the precision automotive parts. The first side contact plate 6 is fixedly installed on the outer left side of the clamping seat 1 to assist in clamping automotive precision parts.

The adaptive grooves 11 are all opened on the outside of the adaptive clamping plate 9 for the movement of the clamping block. The adaptive grooves 11 are provided with sliding grooves 12 inside, and sliding blocks 13 are slidably connected inside the sliding grooves 12. Adaptive clamping blocks 14 are fixedly installed on the outside of the sliding blocks 13. The limiting slide groove 15 is opened on both sides of the outside of the fixture base 1 for internal sliding connection of the limiting slider 16, and the limiting slider 16 is fixedly installed with a connecting frame 17 on the outside, and the connecting frame 17 is fixedly installed with an abutting clamp 18 on the outside. The second side contact plate 19 is fixedly installed on the outer right side of the clamping seat 1 for clamping precision automotive parts. The threaded contact rod 20 passes through the external thread of the second side contact plate 19. A telescopic buffer spring 21 is sleeved on the outside of the threaded contact rod 20. The side thread 22 passes through the external thread of the second side contact plate 19. The front end of the side thread 22 is fixedly installed with a side contact rod 23. By twisting the threaded contact rod 20, the contact plate 18 slides on the clamping seat 1 to clamp the precision automotive parts. Furthermore, by twisting the side thread 22, the side contact rod 23 can be made to abut against the outer sides of the contact plate 18, thereby strengthening the clamping force of the contact plate 18 on the other side of the precision automotive parts.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, positioning mounting plates 2 are fixedly installed on both sides of the fixture base 1. An adjustment groove 3 is provided on the upper part of the positioning mounting plate 2. A fastening plate 4 is slidably connected above the adjustment groove 3. A positioning bolt 5 is threaded through the upper part of the fastening plate 4. The positioning mounting plate 2 and the positioning bolt 5 are used to assist the fixture for placing automotive precision parts in installation on different processing platforms, thereby expanding the scope of use of the fixture. The adaptive clamping block 14 is slidably connected to the adaptive clamping plate 9. The sliding groove 12 and the sliding block 13 are used in conjunction. When the exterior of the automotive precision part is attached to the adaptive clamping block 14, the adaptive clamping block 14 will slide inside the adaptive groove 11 according to the side shape of the automotive precision part, so that the adaptive clamping block 14 is attached to the side of the automotive precision part.
[0020] like Figure 1 , Figure 4 and Figure 5 As shown, the abutment clamp 18 is slidably connected to the fixture seat 1. The front end of the threaded abutment rod 20 is threadedly connected to the outside of the abutment clamp 18.

Next, when the exterior of the precision automotive part is attached to the adaptive clamping block 14, the adaptive clamping block 14 will slide within the adaptive groove 11 according to the side shape of the precision automotive part, allowing the adaptive clamping block 14 to fit against the side of the precision automotive part. Then, by twisting the threaded contact rod 20, the contact clamping plate 18 slides on the fixture base 1, clamping the current precision automotive part. Furthermore, the side screw 22 can be twisted... The side contact rod 23 abuts against the outer sides of the contact clamp 18, thereby strengthening the clamping force of the contact clamp 18 on the other side of the precision automotive parts. This design gives the fixture for placing precision automotive parts the ability to self-adaptive positioning and bidirectional adjustable clamping. This allows it to fit parts of different shapes, reducing the need for designing and replacing special fixtures, and adapting to multi-variety, small-batch production modes. Moreover, the bidirectional clamping mechanism supports quick adjustment of the direction and magnitude of the clamping force, improving compatibility with complex and irregularly shaped parts. After the precision automotive parts are clamped, external equipment can be started to process the precision automotive parts normally. Finally, after completing the installation and use of the fixture for placing precision automotive parts according to the above operations, routine maintenance of the device is required. This completes the use of the fixture for placing precision automotive parts.
