Problems solved by technology

[0002] The compression devices of existing laser welding equipment are mostly fixed compression devices. When welding steel plates, the steel plates are often penetrated, and then the steel plates are stuck to the welding table; and, because the fixed compression devices are far away from the welding area, As a result, the compression effect is not good, and the two steel plates are not bonded together, resulting in welding failure

Abstract

The invention relates to a laser stitch welding compressing device, in particular to a laser stitch welding combined compressing device allowing steel plate laser stitch welding to be completed through fixed compressing devices and a moving compressing device. The fixed compressing devices are disposed on two sides of the moving compressing device. The moving compressing device comprises a moving workbench frame, a moving workbench drive mechanism, a moving workbench, moving carrier wheels, moving compressing wheels, moving compressing wheel drive cylinders, a laser head, and support rollers. A welding head is mounted on a three-dimensional platform of a welding robot. The moving compressing wheels driven and compressed by the moving compressing wheel drive cylinders and moving in sync with the laser head are disposed on two sides of the welding head. The moving workbench frame is arranged below the welding head and is connected with the moving workbench drive mechanism mounted on the moving workbench frame. The moving workbench drive mechanism drives the moving workbench frame to move back and forth along an axis Y. The laser stitch welding combined compressing device has the advantages of wide range of application, simple structure, convenience of mounting, convenience of maintenance and the like.

Description

technical field [0001] The invention relates to a compacting device for laser welding, in particular to a combined compacting device for laser stitch welding which utilizes a fixed compacting device and a moving compacting device to complete laser lap welding of steel plates. Background technique [0002] The compression devices of existing laser welding equipment are mostly fixed compression devices. When welding steel plates, the steel plates are often penetrated, and then the steel plates are stuck to the welding table; and, because the fixed compression devices are far away from the welding area, As a result, the compression effect is not good, and the two steel plates are not bonded together, resulting in welding failure. Therefore, a new pressing device is urgently required to solve this problem. Contents of the invention [0003] In order to solve the above-mentioned problems existing in laser stitch welding of existing steel plates, the object of the present inven...
