Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding devices, in particular to an anti-collision type laser cladding device. Background Art

[0002] Laser cladding is a new surface modification technology.

By arranging the lifting base, the bottom plate and the workbench and other structures, in order to prevent the laser cladding head from colliding with the workpiece during the operation of the device, a special adjustment structure is designed for the device, the bottom plate can be freely raised and lowered under the drive of the lifting base, and the workbench can slide freely on the surface of the bottom plate. In this way, the workpiece on the surface of the workbench can not only move freely but also be raised and lowered freely. In the process of the cladding head processing the workpiece, the user can adjust the position and height of the workpiece according to the time situation to avoid collision.

[0004] In the above scheme, the anti-collision mechanism of the cladding head does not have an emergency stop device. During the use of the laser cladding head, the laser cladding head may cause a hard collision with the workpiece due to improper operation of the operator or irregular workpiece. After the collision, the operator needs to manually stop the movement mechanism. This device that relies on the operator's observation to stop has a lag and cannot minimize the damage; and in the above scheme, two symmetrical clamps need to be manually adjusted to fix the workpiece, which consumes a lot of manual time and is more troublesome to operate. Therefore, the utility model designs an anti-collision laser cladding device to solve the problems existing in the prior art. Utility Model Content
