Bearing type military off-road vehicle rear wheel cover welding clamp system and method

Abstract

The invention discloses a bearing type military off-road vehicle rear wheel cover welding clamp system and method.The clamp system comprises a robot welding workstation and four clamp modules, the first clamp module fixes a middle floor, a left middle floor, a right middle floor and a rear floor, and the second clamp module fixes a left rear longitudinal beam, a right rear longitudinal beam, a floor cross beam and a reinforcing beam; the third clamp module fixes a left wheel cover, a right wheel cover and a suspension buffering support, the first clamp module, the second clamp module and the third clamp module are welded to the back face of a rear wheel cover assembly, three faces of the robot welding work station are arranged around the fourth clamp module, and the fourth clamp module fixes the turned rear wheel cover assembly. The robot welding work station comprises an arc welding mechanical arm, an arc welding gun and a laser tracker, the arc welding gun is fixed to the end of the arc welding mechanical arm, the mechanical arm controls the arc welding gun to move along a welding line path, the laser tracker plays a role in tracking and guiding, and the problems that mixed flow production of the rear wheel cover assembly is difficult, and the welding procedure of the rear wheel cover assembly is complex are solved.

Description

technical field [0001] The present invention relates to the technical field of off-road vehicle welding fixtures, and more specifically, to a load-bearing military off-road vehicle rear wheel housing welding fixture system and method. Background technique [0002] With the development of military off-road vehicles, there is a trend of platformization and serialization. There are more and more models. The rear wheel cover assembly of military off-road vehicles is mostly made of bulletproof steel plate through MAG welding. There are 2 types of axles. The rear wheel house assembly is mainly composed of the middle floor, rear floor, left middle floor, right middle floor, left rear side beam, right rear side beam, left wheel house, right wheel house, etc., while ordinary passenger cars Or the structure of the rear floor of the truck is relatively simple, and it is formed by resistance welding. The structure and manufacturing process of the two are quite different. [0003] The e...
