[0002] As a key component of the automotive chassis system, the machining precision of the shock absorber bracket directly affects the installation stability of the shock absorber and the overall vehicle driving safety. During the production of the shock absorber bracket, grooves need to be machined at specific locations on the bracket to meet subsequent assembly requirements.
[0003] While existing tooling has replaced some manual operations to a certain extent, it still has many shortcomings: On the one hand, the positioning mechanism of this type of tooling is poorly designed and cannot stably and accurately position shock absorber brackets of different models and specifications. During processing, bracket displacement is prone to occur, which in turn affects the opening processing accuracy. On the other hand, the opening execution components of existing tooling are mostly fixed structures, which cannot flexibly adjust the opening width according to actual processing needs. They have poor versatility. When different specifications of slots need to be processed, different tooling must be manually changed, which increases production costs and production preparation time.

[0019] Several punches 7 are equidistantly arranged on the outer wall of the rotating wheel 6 along the circumference of the rotating wheel 6. The operating table 2 is slidably arranged on the base plate 1. A servo slide module 11 is arranged between the operating table 2 and the base plate 1.

[0023] The implementation principle of the CNC grooving device for automotive shock absorbers in this application is as follows: Based on the model and opening width requirements of the shock absorber bracket to be processed, confirm the required 3 sets of locating pins and 7 specifications of punches. If the corresponding positioning pin 3 set is on the operating table 2, directly check whether the positioning pin 3 is firm and without deformation; otherwise, move the operating table 2 through the servo slide module 11 to move the matching positioning pin 3 set to the stamping station and check it. Next, start the drive motor 84, input the target punch 7 number through the control panel, and drive the drive motor 84 to drive the rotating wheel 6 to rotate until the target punch 7 is in place. Then drive the drive motor 84 will stop automatically to ensure that the alignment accuracy is ≤0.1mm.
[0024] Place the shock absorber bracket to be processed on the operating table 2, align the positioning hole of the bracket with the corresponding positioning pin 3, and slowly press the bracket down until the lower surface of the bracket is in contact with the operating table 2 and the positioning pin 3 is fully inserted into the positioning hole of the bracket (if the bracket has a protruding structure, ensure that the protruding part does not interfere with the pressure block 71 and the punch 7). Manually push the bracket gently to check if it is securely fixed. If it is loose, check if the positioning pin 3 is worn or if the positioning hole of the bracket is qualified. After troubleshooting, re-clamp it. During stamping, the hydraulic cylinder is activated, the piston rod extends and drives the mounting bracket 5 to descend. The pressure block 71 first contacts the bracket and is pre-pressed and fixed under the action of the spring 92. Then, the punch 7 passes through the through groove of the pressure block 71 to punch an opening in the bracket. After stamping is completed (hold pressure for 1-2 seconds to ensure that there are no burrs on the edge of the opening), the piston rod of the hydraulic cylinder retracts and drives the mounting bracket 5 to rise and reset. Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model.
