Abstract

A laser welding fixture for a gear comprises a power rotating mechanism, a welding platform, a gear ring clamping mechanism, a wheel disc clamping mechanism and a gear ring tightening mechanism. The welding platform is in fixed transmission connection with the power rotating mechanism, the gear ring clamping mechanism is installed on the welding platform and used for clamping a gear ring axially, the wheel disc clamping mechanism is installed on the welding platform and used for clamping a wheel disc axially, and the gear ring tightening mechanism is arranged on the welding platform and used for clamping the gear ring radially. According to the laser welding fixture for the gear, the gear ring contracts and is clamped through the gear ring tightening mechanism in the radial direction, and therefore the concentricity of the gear ring can be guaranteed; the gear ring is clamped through the gear ring clamping mechanism in the axial direction, so that the end face accuracy of the gear ring is guaranteed, and the anti-splash protection effect is achieved at the same time; the wheel disc is clamped through the wheel disc clamping mechanism in the axial direction, so that welding deformation of the wheel disc is prevented, and welding accuracy is improved. The whole laser welding fixture for the gear can effectively prevent welding deformation, protect the gear, and improve welding accuracy and welding efficiency.

Description

technical field [0001] The invention relates to a tooling, in particular to a gear laser welding jig. Background technique [0002] As a new welding technology, laser welding has the advantages of fast welding speed, high production efficiency, good welding surface quality, large welding depth, small heat-affected zone and environmental protection. With the continuous improvement and development of laser and numerical control technology, it has become an advanced processing method in the field of industrial plate welding. [0003] At present, when laser welding gears, due to the lack of an effective clamping mechanism between the ring gear and the web plate, when the ring gear and the web plate are welded together, the concentricity of the ring gear is not easy to ensure, and the entire gear is prone to radial and end surface deformation, which reduces the welding cost. precision and processing efficiency. Contents of the invention [0004] The purpose of the present inv...
