Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an automotive parts testing positioning fixture. Background Technology

[0002] The manufacturing precision and assembly quality of automotive parts directly affect the safety and reliability of the entire vehicle. Therefore, during the production process, critical components (such as engine housings, braking system components, and suspension parts) require rigorous dimensional inspection, geometric tolerance measurement, and assembly verification. Traditional inspection methods typically employ manual positioning or general-purpose fixtures. Manual clamping is prone to part displacement due to operational errors, affecting the accuracy of inspection data. This is especially true for high-precision features such as holes and curved surfaces. Positioning of irregularly shaped structures (such as turbine blades and body stampings) still relies on customized fixtures, which have poor versatility. Therefore, we have redesigned an automotive parts inspection and positioning fixture. Utility Model Content

Buffer squeezing columns 5 are fixedly installed on one side surface of the second fixed clamping plate 11. The positions of the second fixed clamping plate 11 and the first fixed clamping plate 4 correspond one-to-one. The cross-sectional areas of the second fixed clamping plate 11 and the first fixed clamping plate 4 are the same. The drive motor 12 and the drive threaded rod 7 are connected by a drive connection. The drive threaded rod 7 passes through the interior of the sliding adjustment base 8. The drive threaded rod 7 and the sliding adjustment base 8 are connected by a threaded connection. The sliding adjustment base 8 is located inside the sliding limit groove 6. The sliding adjustment base 8 and the sliding limit groove 6 are connected by a sliding connection.

The second clamping column 9 is located on the top surface of the fixed clamping platform 1. The second clamping column 9 and the fixed clamping platform 1 are connected by a sliding connection. The rotation motor 13 and the drive connecting shaft 10 are connected by a drive connection.

[0019] In the implementation scheme, the drive motor 12 controls the rotation of the drive threaded rod 7, which in turn drives the sliding adjustment base 8 to slide and adjust its position within the sliding limit groove 6. This directly adjusts the distance between the first clamping post 2 and the second clamping post 9.

Example 2:

[0020] Please see Figure 1-4 This utility model provides a technical solution: an automotive parts inspection and positioning fixture, including a sliding limiting post 14 fixedly connected to the top of one side of a sliding adjusting chassis 8, a sliding limiting hole 15 opened inside the sliding limiting hole 14, and a sliding connecting rod 16 movably connected inside the sliding limiting hole 15; a first fixed clamping plate 4 including a mounting plate 17 and a snap-fit ​​plate 18, a snap-fit ​​groove 19 opened on one side surface of the mounting plate 17, and a snap-fit ​​block 20 fixedly installed on the back side of one side of the snap-fit ​​plate 18; a buffer squeezing post 5 including a shrinking bottom post 51, and a telescopic squeezing post 51 telescopically connected to the top of one side of the shrinking bottom post 51.

The second fixed clamping plate 11 can also be directly disassembled into an installation plate 17 and a snap-fit ​​plate 18, and both sides can be replaced simultaneously.

[0022] Working principle:

[0023] By setting the drive motor 12 to control the rotation of the drive threaded rod 7, the drive threaded rod 7 drives the sliding adjustment base 8 to slide and adjust its position inside the sliding limit groove 6, thereby directly adjusting the distance between the first clamping column 2 and the second clamping column 9. The first fixed clamping plate 4 and the second fixed clamping plate 11 are used to clamp and fix the automotive parts for detection. The first fixed clamping plate 4 and the second fixed clamping plate 11 are both provided with buffer extrusion columns 5 on one side surface. During the extrusion of the automotive parts, the telescopic extrusion rod 52 directly retracts into the shrinkage base column 51. The buffer shrinkage spring 53 is subjected to the extrusion effect. The telescopic extrusion rod 52 directly contacts the automotive parts for operation, realizing the extrusion and fixing operation for automotive parts of different specifications and shapes, improving the extrusion and fixing adaptability of the device. The rotating motor 13 can directly control the rotation of the drive connecting shaft 10, thereby enabling the angle adjustment operation of the second fixed clamping plate 11, and simultaneously adjusting the angle of the automotive parts, improving the detection and use flexibility of the device.

[0024] By setting the sliding limit post 14 to slide on the sliding connecting rod 16, the position adjustment of the sliding adjustment base 8 is assisted, and the movement stability of the second clamping post 9 is improved. The first fixed clamping plate 4 and the second fixed clamping plate 11 have the same structure. The first fixed clamping plate 4 can be separated into the mounting plate 17 and the snap-on plate 18. The snap-on block 20 is directly inserted into the snap-on groove 19 to complete the snap-on installation between the mounting plate 17 and the snap-on plate 18. This facilitates the direct disassembly and replacement of the snap-on plate 18, and makes it easier to use snap-on plates 18 of different specifications and sizes, thus improving the flexibility of the device. The second fixed clamping plate 11 can also be directly disassembled into the mounting plate 17 and the snap-on plate 18, and both sides can be replaced at the same time.
