Problems solved by technology

[0003] The welding of components such as bushings and lifting lugs of battery trays of different specifications and sizes is also different, and battery trays have high requirements for the accuracy of the welding position of components: the distance deviation between lifting lugs shall not exceed 0.5mm, and the distance between the harness bracket and the frame The distance deviation shall not exceed 0.5 mm, and the distance deviation between the wire harness bracket and the ground shall not exceed 0.5 mm; therefore, a welding jig is required to ensure the accuracy of the welding position of the component during the welding of the assembly, and the welding jig in the prior art can only be used For battery trays of a single specification and size, different welding fixtures are required for battery trays of different specifications and sizes

Abstract

The invention discloses an automatic detection flexible welding fixture, which includes a fixture base and a welding robot controller. A switching sliding rail is arranged on the fixture base, a switching sliding seat is arranged on the switching sliding rail, a first laser range finder for detecting the position of the switching sliding seat and a second laser range finder for detecting the position of a workpiece are arranged on the fixture base, the first laser range finder and the second laser range finder are arranged at the both ends of the length direction of the switching sliding railcorrespondingly, and the first laser range finder and the second laser range finder are both connected with the welding robot controller through signals. According to the automatic detection flexiblewelding fixture and a working method thereof, one welding fixture can be used for processing battery trays with various specifications and sizes in a welding mode, whether workpiece placement meets the set requirements or not can be automatically detected, and welding robot control programs corresponding to the workpiece length specifications are automatically selected.

Description

technical field [0001] The invention relates to the technical field of a welding operation auxiliary device, in particular to an automatic detection flexible welding fixture and a working method thereof. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. At present, a large number of companies and brands of electric passenger cars, electric buses, and electric trucks have emerged in China. The specifications and sizes of battery trays required by different companies and brands of electric vehicles are also different. [0003] The welding of components such as bushings and lifting lugs of battery trays of different specifications and sizes is also different, and battery trays have high requirements f...
