Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle frame production, in particular to an electric vehicle frame flipping device. Background Art

[0002] Usually, the production of electric vehicles needs to rely on production lines with operating stations. According to the whole vehicle assembly process, the electric vehicle frame is fixed on the bracket. After some parts are assembled, the semi-finished electric vehicle frame needs to be turned over to facilitate the continued assembly or welding of the remaining parts. The existing electric vehicle frame is generally clamped by a fixture. After the tooling welding on one side of the electric vehicle frame is completed, the electric vehicle frame needs to be manually turned over and clamped in the opposite direction, which reduces the work efficiency and affects the convenience of tooling welding.

The clamping cylinder has the advantages of large clamping force and small space occupation, and the opening and closing action is smooth and fast. At the same time, it can avoid deformation of the electric vehicle frame, improve production efficiency, and improve product quality.

[0013] In an embodiment of the present invention, the two clamping jaws each include a notch for placing the frame, and an abutment block for abutting against each other.

[0014] To implement the above technical solution, the notch in the clamp is used to place the electric vehicle frame, and the abutment blocks are used to abut each other to prevent the electric vehicle frame from being deformed due to excessive force.

[0015] In one embodiment of the present invention, the pushing device is a three-rod cylinder.

[0016] To implement the above technical solution, the three-rod cylinder is set up to improve the stability during the lifting process, avoid shaking or trembling during the lifting process, and provide precise positioning and movement, which is suitable for the welding needs of electric vehicle frames at different heights.

[0017] As described above, an electric vehicle frame flipping device of the utility model has the following beneficial effects: the clamping assembly described in the present application is used to clamp the electric vehicle frame.
