The present disclosure provides a suspended-type spot welding device convenient for welding and assembling of various vehicle models, falling within the technical field of welding. A suspension frame, a rotation piece, a spot welding machine body, a first electrode holder and a second electrode holder are included. According to the present disclosure, by approaching a welding seam with a camera, a position of the welding seam is displayed by a display. Under the action of a balancing weight, a position of the display is always kept above, which is convenient for workers to know the position of the welding seam through the display at any time and avoids the display from moving with a spot welding machine body, thus facilitating the workers to weld the welding seam.

Disclosed is an anti-skip and wear-resistant automatic positioning tool for welding production line based on digital twinning. Insertion holes are uniformly disposed on a base plate, and the insertion holes serve to be inserted with support columns. Flat plates are fixedly connected to telescopic air cylinders. Telescopic pulling columns are hinged to upper ends of the support columns. Tabletop cleaning components are mounted on the base plate. In the present disclosure, welding slag adhered to surfaces of clamping plates can be effectively removed, preventing issues when clamping the next welding vehicle body. This avoids minor scratches or dents on a surface of the vehicle body caused by pressure from particles of the welding slag, ensuring that the welding process is not affected by the presence of welding slag.

Disclosed is a clamping device having an automatic direction adjustment function in a vehicle body welding conveying line, including a conveying frame. A driving motor is fixedly connected to a side wall of the conveying frame, and an output shaft end of the driving motor is fixedly connected to a rotating shaft I. The present disclosure facilitates the adjustment of a direction when vehicle bodies to be welded are conveyed on a turning conveying line, and vehicle bodies being conveyed can be corrected to the same horizontal state, to avoid a situation where the clamping device on the conveying line cannot smoothly clamp inclined vehicle bodies for conveying because the vehicle bodies cannot be in the same horizontal plane when being put in.
