[0010] 1. The crawler beam lap welding fixture of the excavator is equipped with a positioning seat and a crawler beam. The crawler beam is symmetrically installed at the front, rear, left and right ends of the positioning seat, so that the left and right crawler beams can be manufactured on one fixture. At the same time, by using the symmetrical positioning seat of the motor head, the consistency of the product dimensions of the left and right parts is ensured, reducing the use of one set of fixtures and thus saving space.

[0011] 2. The crawler beam lap welding fixture of the excavator is provided with a first rib plate positioning block, a first bending plate positioning block, a first side plate positioning block, a second rib plate positioning block, a second bending plate positioning block, a second side plate positioning block and a tail positioning seat. By using the mutual cooperation between them, the rib plate can be accurately positioned by the first rib plate positioning block and the second rib plate positioning block, and the first bending plate positioning block and the second bending plate positioning block can be used as auxiliary positioning points to help workers complete the welding work more accurately and improve the efficiency and accuracy of welding. Due to the accuracy of the first side plate positioning block and the second side plate positioning block, the adjustment and calibration time before welding can be significantly reduced, the welding efficiency is improved, and the position of the tail can be ensured to be accurate during the welding process. The tail positioning seat can ensure the accurate position of the tail. Therefore, during the welding process, its components are accurately placed in the predetermined position to ensure the structural integrity and functional realization of the entire crawler beam, thereby limiting its degree of freedom in space and ensuring its position to be accurate during welding.
