Description

Technical Field

[0001] The utility model relates to the technical field of textile frame processing, and more specifically to an automatic positioning and fastening device for welding a textile frame. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken during welding.

[0003] During the welding process of textile frames, operators often use corresponding automatic positioning and fastening devices to position and fix the textile frames. In actual use, although the existing positioning and fastening devices have basic positioning and fixing functions, most general positioning and fastening devices can only clamp and fix the frame shells of the same size. When frames of different sizes need to be fixed, operators usually disassemble and replace the clamps, which not only increases the labor intensity of the operators, but also reduces the application scope of the device. Therefore, it needs to be improved. Utility Model Content
