[0013] Compared with the prior art, the utility model has the advantages that:

[0014] High precision and stability: the mechanism ensures high precision and stability of clamping and positioning by designing the product bottom surface as a fixed reference surface. Regardless of the size of the product, the rotating shaft only needs to be rotated to quickly adhere to the desired position, without the need for manual positioning and clamping, and the operation is convenient and fast.

[0015] Reducing labor operation cost: the traditional manual spot welding method avoids the problems of difficult alignment and easy deviation. The employee only needs to put the product into the product groove with tweezers, and the clamp can quickly clamp and position, greatly saving time, reducing the probability of employee errors, and improving production efficiency.

[0016] Improving labor efficiency and saving time: the clamp can ensure high precision and stability of repeated clamping and positioning, and the operator does not need to consider whether the product is placed in place, greatly improving labor efficiency and saving half of the material placing time.

[0018] Saving labor alignment time cost: the hole groove quick clamping and positioning mechanism can be automatically guided and clamped under the action of the clamping groove block, saving a lot of manual alignment time and reducing product defects caused by inconsistent operators.

[0019] Convenient to assemble and maintain: the parts of the composed mechanism have simple structures, all accessories can be directly processed using a milling machine and a grinding machine, the precision is easy to control, the clamp can be quickly manufactured, and the maintenance period is short.

[0020] High versatility and cost saving: the entire structural mechanism is hierarchical, the clamp can be made into a universal part, and only the intermediate body needs to be made when changing similar products, greatly saving costs without the need for complete production.
