The driving cylinder controls the pressure plate and the connecting ears to cooperate with each other, so as to clamp and tighten the frame between the pressure plate and the connecting ears.

[0011] In the above-mentioned automobile test bench assembly production line, one side of the pressure plate is hingedly connected to the corresponding part of the connecting ear. The driving cylinder can drive one side of the pressure plate to rotate circumferentially along the central axis of the hinge and clamp and tighten the frame.

[0012] In the above-mentioned automobile test bench assembly production line, the welding robot is arranged in a six-axis structure. The welding robot, rotating bracket, clamping tooling, and frame located on the clamping tooling are controlled by a control system, so that the welding robot can realize multi-directional automatic welding of the frame.

[0013] In the above-mentioned automobile test bench assembly production line, the frame automatic welding is realized by controlling the welding mechanism, the moving mechanism and the roller assembly line by the control system.
