Application of laser welding machine in automobile clutch manufacturing

The automobile clutch is located in the flywheel shell between the engine and the gearbox, and the clutch assembly is fixed to the rear plane of the flywheel by screws, and the output shaft of the clutch is the input shaft of the gearbox.

During the driving process, to adapt to constantly changing driving conditions, shifting different gears is often used. If there is no clutch to temporarily separate the engine from the gearbox, the meshing gears in the gearbox will not be removed from the load, the pressure between the geared teeth surface is large and difficult to be separated, and the other gear to be meshed will be difficult to engage due to the fact that the circumference speed of the two is not equal. Even if it is forced into meshing, a large impact betweeen the teeth will be generated, which will easily damage the machine, so the welding requirements for the clutch are very high.

For the welding of automobile clutch pressure plate, an automatic laser welding system is designed, which is mainly composed of fixture unit, jacking positioning and rotary mechanism, welding station etc. When the fixture is designed, the center hole of the base is used as the positioning center, and two sets of spring latch mechanisms are installed on both sides of the bearing seat of the fixture to ensure the free turning of the rotating mechanism and the stability during the production process.

The Laser welding machine uses high energy pulse laser to locally heat the material in a small area. The energy of the laser diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool for welding purposes. Compared with the traditional welding method, the automotive clutch laser welding machine has the advantages of large welding strength, small heat affect zone, non-mechanical contact between the laser beam and the workpiece, and easy automation.

The YAG laser welding machine of Shenzhen Sunlaser can almost perfectly meet the requirements in the processing of auto parts, and has good performance in terms of efficiency, economy, safety, strength and corrosion resistance. The value of the car parts accounts for a large proportion of the cars total value. The laser welding process can significantly improve the performance of the car parts and the quality of the car.
