Abstract

The invention relates to a polyhedron rotation welding tool commonly used for multiple vehicle bodies. The polyhedron rotation welding tool comprises an installation base, a locking assembly and a polyhedron rotation assembly. The polyhedron rotation assembly comprises a rotation polyhedron. Working faces corresponding to four different vehicle types are arranged on the four side faces of the rotation polyhedron respectively. A hollow rotating shaft rotating around the rotation polyhedron and a thrust shaft connected with the locking assembly and pushing the rotation polyhedron to lock or unlock rotation are arranged in the rotation polyhedron. A plurality of second guide sleeves matched with butt joint pins of different vehicle types are arranged on one end face of the rotation polyhedron. The locking assembly is pushed to be loosened through the thrust shaft, then the rotation polyhedron is driven to rotate, the second guide sleeves are in butt joint with the butt joint pins of the corresponding vehicle types, and therefore the working faces of the different vehicle types can be replaced for work. Compared with the prior art, the polyhedron rotation welding tool has the beneficial effects of being small in structure and occupied space, low in cost and the like.

Description

technical field [0001] The invention relates to welding production line equipment in the automobile industry, in particular to a polyhedron rotary welding tool shared by multiple vehicle bodies. Background technique [0002] In the welding production line of an automobile company, at the initial stage of design, the jig for positioning the car body, the skid or the trolley for conveying can basically meet the needs of one or two models of each production line for mixed production. With the development of the automobile market, there are more and more car models, and the replacement cycle is getting shorter and shorter. These changes pose a severe test to the car main engine manufacturers. The original model planning single production method not only has low production efficiency, but also Moreover, the versatility of the equipment is low, which can no longer meet the current development trend of automobile planning. Faced with the production planning of new models, main eng...
