2. Through the clamping of the clamping device 404 and the matching of the positioning groove 405, the side plate 102' can be quickly positioned, and then the positioning component 1 304 is used to quickly locate the lug plate 1 2' welded by the station 3, ensuring that the Accuracy and stability of the positioning between the side plate 102' and the workpiece welded at the station 3 in the second fixture unit 401;

3. Through the cooperation of the positioning sleeve 505 with the first pin 506 and the second pin 507, the second ear plate 3' can be quickly positioned, and the positioning assembly 1 304 can be used to accurately and quickly locate the first ear plate 2', which ensures the middle side of the third fixture unit 501. The accuracy and stability of the positioning between the first plate 102' and the second ear plate 3';

4. The welding speed and welding effect can be improved by the welding robot 1 .

5. Fast and stable clamping of the workpiece to be welded can be achieved through the fixture unit in each station, and with the welding robot 1, fast, efficient and stable welding can be achieved.

For the above-mentioned connection, setting and installation, a suitable connection method can be selected from the existing prior art, such as welding, riveting, screw connection, bonding, pin connection, key connection, elastic deformation connection, snap connection, Interference connection and injection molding are used to achieve structural connection. In actual production, the connection method with lower cost and high production efficiency should be selected according to the production conditions under the premise of realizing the connection purpose and ensuring the connection effect.
