Laser welding machine with laser head provided with protection assembly

Abstract

The invention discloses a laser welding machine with a laser head provided with a protection assembly. The laser welding machine comprises a transverse arm, and the transverse arm is installed on thelaser welding machine. The laser head is installed at the front end of the transverse arm. A first fixing block is welded to the front end of the transverse arm, and a servo motor is fixed to the upper end of the first fixing block. The end portion of an output shaft of the servo motor is fixedly provided with a screw rod through a coupler, and the lower end, away from the servo motor, of the screw rod is rotationally connected with a supporting disc through a bearing. The supporting disc is fixed to the lower side of the laser head, and a transmission nut is connected to the screw rod in a threaded transmission manner. A moving disc is inlaid in the outer side of the transmission nut, and a through hole is formed in the center position of the moving disc. The laser head penetrates the moving disc through the through hole, and a protection cover is arranged on the outer side of the lower end face of the moving disc. The laser head is located in the center position of the interior of the protection cover, and a guide mechanism is arranged on the side, away from the screw rod, of the moving disc. The periphery is isolated and protected when the laser head works, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of welding machine accessories, and in particular relates to a laser welding machine with a protective assembly on the laser head. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. It is mainly used for welding thin-walled materials and low-speed welding. The welding process is of heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the The workpiece melts to form a specific molten pool. [0003] At present, laser welding is mostly carried out by laser welding machine. The welding head of laser...

Problems solved by technology

[0004] The object of the present invention is to provide a laser welding machine with a protective assembly for the laser head, to solve the above-mentioned background technology, the laser head on the current laser welding machine is exposed to the outside, there is no protective device around, and the surrounding of the laser head when welding Impurities such as flames and welding slag will be generated, and the impurities will splash everywhere. Due to the high temperature of the impurities, it is easy to scald the staff when splashed out, and may cause fire problems
