Laser beam welding workstation

Abstract

The invention relates to a laser welding work table, which comprises a pedestal (31) and a positioning seat (14), a drive unit (34) and a hold-down gear (35) which are fixed on the pedestal (31), wherein the positioning seat (14) is provided with a central hole (32) in which an apical ring (13) is arranged; the edge of the central hole (32) is also provided with a plurality of hold-down mechanisms (33) which can press and fix workpieces into the central hole (32); the drive unit (34) can drive the positioning seat (14) to rotate around the center of the central hole (32) of the positioning seat (14), so as to drive the workpieces to be welded to rotate around the center of the positioning seat (14); and the hold-down gear (35) is arranged on the positioning seat (14) and can press down upper surfaces of the workpieces and simultaneously rotate along with the workpieces. The laser welding work table can accurately fix and position the workpieces, can make the workpieces rotate around the center, is convenient to realize high-efficiency laser welding, realizes water circulating cooling of the positioning seat, prevents the workpieces from being heated and deformed, is provided with a swivel base so as to be capable of adjusting the angle of the swivel base and a bottom plate, and is convenient to obtain best laser welding effect.

Description

technical field [0001] The invention relates to a welding workbench, in particular to a laser welding workbench. Background technique [0002] In modern processing technology, laser welding operation has its unique convenience, so it is widely used. In the application of laser welding technology, in order to have a more convenient application for the clamping and operation of welding large, medium and small round workpieces, such as laser welding gas generators, laser welding workbenches are required. However, the existing fixtures on the market can only achieve single-point clamping. Through manual adjustment, the work efficiency is too low, and the positioning accuracy is also very low; the welding effect is also unstable, and the welding effect required by the design cannot be achieved, and the yield rate is low. , cannot be used for batch automatic production. In short, the existing laser welding workbench has the following disadvantages: 1. The positioning of the weld...
