Welding clamp and matched feeding and discharging tool thereof

Abstract

The welding clamp comprises a base, a clamping assembly is arranged on the base and used for clamping a shell part to be welded and a bent plate, the clamping assembly comprises a first clamping mechanism, a second clamping mechanism, a third clamping mechanism and a fourth clamping mechanism, and the first clamping mechanism and the third clamping mechanism are oppositely arranged and are the same in structure; the second clamping mechanism and the fourth clamping mechanism are oppositely arranged and have the same structure; a first air cylinder on the first clamping mechanism drives a first clamping plate to rotate and is matched with the top of the first supporting plate so as to clamp the shell part. A bending plate is fixed to a second clamping plate on the second clamping mechanism, and the bending plate is arranged on the side portion of the shell part to wait for a welding machine to weld and fix the shell part and the bending plate. According to the device, synchronous clamping is achieved through the four clamping mechanisms, mounting and positioning of the two shell parts and the bent plates on the two sides can be completed, the clamping work efficiency is high, the two shell parts can be synchronously grabbed through the matched feeding and discharging tool, a welding clamp is matched, and the work efficiency of the whole production line is improved.

[0002] In the prior art, when the welding machine performs the welding operation on the workpiece, the two workpiece products to be welded need to be clamped and fixed, and the design of the welding fixture generally needs to be designed according to the specific product, such as welding on both sides of the shell. The bent plates are welded on both sides of the shell. The conventional design requires the use of three clamping mechanisms, which are used to clamp the shell workpiece and two bent plates respectively. The three clamping mechanisms are located on one base. Each clamping and positioning requires It takes a long time to operate three times, the operation efficiency is low, and the labor intensity of the workers is high

[0003] The workpieces on the welding fixture are generally picked and placed manually. For mass production, workers have high repetitive labor intensity, time-consuming and low production efficiency.

Therefore, robots are generally used to assist in clamping the workpiece for pick-and-place. For the process of welding the bent plate on the side of the shell, it is generally necessary to design at least two robots to clamp the shell and the bent plate respectively. Sequential pick-and-place operation, taking a welding jig of a shell piece as an example, it is necessary to grab the shell piece from the raw material area and place it on the shell piece station of the welding fixture, and then take the two bent plates sequentially and place them To the bending plate station of the welding fixture, the bending plate is located on the side of the shell part. From the above operations, it can be seen that although the current conventional robot-assisted clamping design saves labor, the operation process is also relatively complicated and the time saving is limited.
