[0002] Welding is the main process of steel structure production enterprises. Traditional welding technology is completed by manual labor, and the welding accuracy depends on skilled workers. Since welding operations have high requirements for skilled workers, there will be errors in welding accuracy during continuous welding operations. Strictly following the standard accuracy requirements will lead to low welding efficiency. In order to improve welding accuracy and efficiency, enterprises use automated equipment to replace workers. Welding robots are our common automatic welding equipment. Welding robots can achieve precise positioning and high-precision requirements.

[0003] Regarding the above-mentioned related technologies, the inventor believes that when the robotic arm of the welding robot welds the workpiece, when clamping the workpiece, the traditional clamp is not stable enough to clamp the workpiece, and it is more likely to shake, affecting the accuracy of the robot's robotic arm welding. Therefore, a clamp that is convenient for the robotic arm to weld is proposed to solve the above problem.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

The connecting plate 18 is hingedly connected to the driving arm 7 and the connecting rod 8. Through the rotation of the driving arm 7, the driving arm 7 drives the connecting plate 18 to move, and then the connecting plate 18 drives the connecting rod 8 to rotate, so that it rotates to a fixed position. The outer wall of the connecting rod 8 is fixedly connected to a fixing rod 11, and the outer wall of the fixing rod 11 is provided with a contact assembly. The fixing rod 11 is driven to rotate by the connecting rod 8, so that the fixing rod 11 fixes the workpiece through the contact assembly, thereby improving its stability. A plurality of auxiliary fixing assemblies are provided at the four corners of the base 1, which facilitate further stable fixation of the four corners of the workpiece through the auxiliary fixing assemblies, thereby improving its fixing effect.

[0022] The base 1 is located between two brackets 4 and is fixedly connected to a plurality of fixing frames 2. The plurality of fixing frames 2 are designed in a rectangular shape and are distributed on the outer wall of the base 1. The outer wall of the base 1 is fixedly connected to a plurality of limit frames 3. The plurality of fixing frames 2 facilitate the contact assembly to fix the workpiece, and at the same time, cooperate with the plurality of limit frames 3 so that the inner wall of the workpiece fits with the plurality of fixing frames 2, and the outer wall of the workpiece fits with the plurality of limit frames 3, thereby facilitating its stable fixation.

[0023] The auxiliary fixing assembly includes multiple fixing seats 5, which are conveniently fixed and installed on the four corners of the base 1. The outer walls of the multiple fixing seats 5 are fixedly connected to the support rods 10, and the outer walls of the support rods 10 are fixedly connected to the support frame 19. The outer wall of the support frame 19 is rotatably connected to the rotating frame 13.

The outer wall of the sliding rod 16 is fixedly connected to the fixed head 17, and the rotating frame 13 is driven to rotate, so that the rotating frame 13 is facilitated to drive the sliding rod 16 to move through the connecting arm 15, so that the rotating frame 13 pushes the sliding rod 16 to move through the connecting arm 15, and then the sliding rod 16 drives the fixed head 17 to be fixed to the four corners of the workpiece, effectively improving the fixing effect of the workpiece.

[0024] Two handles 6 are fixedly connected to the outer walls of both sides of the base 1 , and the two handles 6 are used to facilitate the movement of the clamp.

[0025] The contact assembly includes a long rod 20, which is fixedly connected to the fixed rod 11. The outer wall of the fixed rod 11 is rotatably connected to a fixed block 12, which facilitates fixing the workpiece through the fixed block 12.

[0026] The implementation principle of a clamp that is convenient for robotic arm welding in an embodiment of the present application is as follows: first, by fitting the bottom inner wall of the workpiece with the fixed frame 2, and the bottom outer wall of the workpiece with multiple limit frames 3, the worker pulls the pull rod 9, so that the pull rod 9 drives the driving arm 7 to rotate, and the driving arm 7 drives the connecting rod 8 to rotate through the connecting plate 18, and then the connecting rod 8 drives the fixed rod 11 to rotate, so that the fixed rod 11 drives the fixed block 12 to resist the outer wall of the workpiece through the long rod 20, and then the symmetrically arranged multiple fixed blocks 12 stabilize the workpiece, and then by rotating the rotating frame 13, the rotating frame 13 drives the sliding rod 16 to move forward through the connecting arm 15, and then the sliding rod 16 drives the fixed head 17 to further stabilize the four corners of the workpiece, thereby improving the stability of the workpiece.
