Description

Technical Field

[0001] The utility model relates to the technical field of automobile rear bumper welding, and particularly relates to an automobile rear bumper welding device. Background Art

[0002] The bumper can absorb and mitigate external impact forces, playing a protective role for the front and rear parts of the vehicle body. It is an important safety performance component of the automobile. In the actual production process of the bumper, there are mainly three welding forms: resistance welding, induction welding, and laser welding. Among them, resistance welding has become the most preferred method for bumper production due to its best cost performance, low equipment price, low product forming requirements, and easy quantification of welding parameters and performance.

[0003] According to a Chinese patent with the publication number "CN204657722U", an automobile bumper welding device is disclosed, which includes a welding machine for welding bumper workpieces, and also includes a PLC controller, a length measuring device for measuring the actual traveling distance of the bumper workpiece, and an optical fiber hole counting device for detecting the hook removal sleeve holes on the bumper workpiece. The length measuring device and the optical fiber hole counting device are both arranged at the initial end in the traveling direction of the bumper workpiece; the input ends of the PLC controller are respectively connected to the output ends of the length measuring device and the optical fiber hole counting device through wires, and the output end of the PLC controller is connected to the controlled end of the welding machine controller through a wire. This utility model realizes the automatic correction function of the solder joint position according to specific process holes, ensures the uniqueness of the solder joint position, and improves the consistency of the automobile appearance on the premise of ensuring the welding quality.

[0004] However, although this patent can improve the welding quality of the bumper, the way to fix the bumper is to use multiple bolts for fixation. This fixation method requires the cooperation of disassembly tools such as screwdrivers. If there are no disassembly tools such as screwdrivers at hand, it is very difficult to fix the bumper, which in turn leads to a lower processing efficiency. Therefore, an automobile rear bumper welding device is proposed to solve the above-mentioned problems. Content of the Utility Model
