Welding jig for robot to automatically weld anti-collision beam

Abstract

The invention provides a welding jig for a robot to automatically weld an anti-collision beam, and relates to the field of welding operation auxiliary devices. The welding jig for the robot to automatically weld the anti-collision beam comprises a welding platform, supporting mechanisms are fixedly connected to the two sides of the top of the welding platform correspondingly, a left energy absorption box and a right energy absorption box are arranged at the tops of the two supporting mechanisms correspondingly, and an anti-collision beam body is mounted at the top between the left energy absorption box and the right energy absorption box; and the two sides of the top of the welding platform are fixedly connected with two side fixing mechanisms corresponding to the left energy absorption box and the right energy absorption box correspondingly, and the center of the top of the welding platform is fixedly connected with a middle positioning mechanism corresponding to the anti-collision beam body. According to the welding jig, through designing a novel welding fixture, the position accuracy of the anti-collision beam is guaranteed, the welding deformation is effectively reduced, meanwhile, by using the welding fixture, the position positioning of the anti-collision beam is simplified, the production efficiency of workers can be greatly improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of welding operation auxiliary devices, in particular to a welding jig for robots to automatically weld anti-collision beams. Background technique [0002] Electric vehicle (BEV) refers to a vehicle powered by a vehicle-mounted power supply and driven by a motor to drive the wheels. There are a large number of brands of electric passenger cars, electric buses, and electric trucks. The anti-collision beam is a device used to reduce the vibration force of the vehicle. Its two ends are connected with low-speed energy-absorbing boxes with low yield strength. The form of bolts is connected to the longitudinal beam of the vehicle body. The low-speed energy-absorbing box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage of the impact force to the longitudinal beam of the vehicle body. In this way, it can protect the vehicle effect. [0003] At present, t...
