Technical Field

[0001] The utility model relates to the technical field of positioning, in particular to a positioning device for processing plastic pipes. Background Art

[0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. With the rapid development of the plastics industry and the continuous improvement of plastic performance, plastic parts have been more widely used. Plastic parts are replacing traditional metal parts in different fields, which can simplify product structure and save manufacturing costs. Plastic pipes are pipe fittings made of plastic.

[0003] However, the prior art still has some shortcomings. In the prior art, during the processing, the position of the feature to be processed is often offset due to bending, resulting in a large number of defective products. Therefore, it is necessary to position it before processing it.

[0004] Therefore, we propose a positioning device for plastic tube processing to solve this problem. Summary of the invention
