Auxiliary welding support device for plate having hanging structure

Abstract

The invention discloses an auxiliary welding support device for a plate having a hanging structure. The auxiliary welding support device comprises a bearer whose bottom is supported by an lower plate, a support assembly rotatingly connected with the bearer through a rotating shaft, and a first spring disposed between the bearer and the support assembly. The upper surface, far away from the bearer, of the support assembly clings to an upper plate, the rotating shaft extends in the width direction of the plate, and the support assembly vertically pivots on the rotating shaft under the function of the first spring. A locating assembly is inserted between the support assembly and the bearer, and the locating assembly is slidingly fixed to the bearer in the transverse direction. According to the auxiliary welding support device, a workpiece will not be fixed through clamping just like the prior art, the auxiliary welding support device is simpler in structure and smaller in size, and influence between the device and a welding gun can be avoided, so the maneuverability of welding technology can be improved.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary tooling, in particular to an auxiliary welding support device for plates with suspended structures. Background technique [0002] During the welding process of the car body, there is often a panel overlap structure where the side wall is overlapped and the lower part is suspended. For this workpiece structure with the lower part suspended, the fixture usually adopts such as figure 1 The multi-stage turning mechanism shown is used to realize the positioning of the plate. However, the existing fixture has many degrees of freedom, and the positioning needs to be realized through the joint action of the upper and lower clamping parts, resulting in a more complicated structure of the fixture, a large space occupation, and the large size of the supporting device, which is easy to interfere, such as welding torches. Affects welding operability. [0003] Therefore, to provide a welding auxilia...
