The quick positioning device 2 is used to quickly position the processed parts. The inner side of the positioning block 7 is fixedly connected with a friction pad 16. The friction pad 16 is made of rubber, and the positioning block 7 can clamp the object that fits therewith;

[0033] Specifically, the frame 1 serves as the supporting frame of the entire device, and the friction pad 16 can effectively protect the surface of the processed parts from damage while ensuring the clamping force, and ensure the close fit and firm fixation between the tooling and the parts, protecting the surface of the parts from damage.

The controller 17 can control the telescopic rod 11 to quickly replace the supporting mechanism.

[0038] Working principle: When it is necessary to adjust and switch different clamps, start the telescopic rod 11 to push the fixed plate 10 to the right, so that the sliding sleeve 9 can move to the right together, so that the pull rod 8 can rotate along the rotating shaft 13, and at the same time, the rotating shaft 2 14 slides along the guide groove 5, thereby driving the positioning block 7 to slide outward along the guide groove 5, thereby loosening the clamps between the positioning blocks 7, and then place the clamp to be replaced in the middle of the right side of the hollow block 3. Start the telescopic rod 11 to make the sliding sleeve 9 move to the left along the fixed column 15, pull the pull rod 8 to move together, and then drive the rotating shaft 2 14 to slide in the guide groove 5, so that it can drive the positioning block 7 to fix the replaced clamp;

[0039] When processing an object, the part to be processed is pre-aligned by the top 203, and at the same time, the transmission shaft 4 is rotated to drive the hollow block 3 and the rotating column 201 to rotate, thereby driving the top tooth 202 to rotate to drive the top 203 to position, and drive the processing positioning shaft 204 to position the center hole of the product.
