Pressing welding device and process for high-power optical fiber laser welding speed changer gear

Abstract

The invention discloses a pressing welding device and process for a high-power optical fiber laser welding speed changer gear. A laser welding mechanism, a pressing mechanism, a carrying mechanism and a feeding and discharging station are arranged on a work table, a welding station is arranged under the laser welding structure, a pressing station is arranged under the pressing mechanism, the pressing welding device also comprises a gear clamp, the gear clamp comprises an upper layer gear ring clamp plate and a lower layer gear tray, a plurality of gear ring accommodating holes through which gear rings can pass are formed in the upper layer gear ring clamp plate, a gear ring support sheet mechanism for supporting the gear rings is arranged in the gear ring accommodating holes, a plurality of gear struts are arranged in the lower layer gear tray, the positions of the gear struts correspond to the positions of the gear ring accommodating holes, and a plurality of clamp plate positioning posts used for realizing the combination positioning with the upper layer gear ring clamp plate are also arranged on the lower layer gear tray. The pressing welding device and the pressing welding process have the advantages that the one-step pressing of a plurality of groups of gears and gear rings can be realized, the pressing and welding connection is good, and the processing efficiency of the speed changer gear is high.

Description

technical field [0001] The invention belongs to the technical field of gear press-fit welding, and in particular relates to a press-fit welding device and process for high-power optical fiber laser welding transmission gears. Background technique [0002] In the gearbox of motor vehicles such as automobiles or motorcycles, there is usually a transmission gear for shifting gears. This transmission gear is mainly welded after the gear and the ring gear are pressed together. The pressing method of the gear and the ring gear is manual assembly and single pressing of the machine. Only one set of gear and ring gear can be pressed at one time. There are two main welding methods for the gear ring gear. One is that the stepping motor drives a single gear to rotate for laser welding. The loading and unloading is manual loading and unloading, and each time a piece is welded, manual loading and unloading is required, and the efficiency is extremely low; The first is a turntable gear we...
