A three-dimensional laser cutting robot for plates

Abstract

The invention discloses a three-dimensional laser cutting robot for plates. On the basis of the existing mechanical arm with a laser cutting head, a frame with a triangular prism frame structure is arranged directly in front of the base of the mechanical arm. There are two sets of dynamic and static clamping bodies on the opposite sides of the left and right expansion bodies. The dynamic and static clamping bodies are equipped with fixed automatic plate clamping hands and movable plate automatic clamping hands. The fixed plate automatic clamping The hand and the movable sheet automatic gripper can be automatically clamped on the side of the vertically placed sheet respectively, and the movable sheet automatic gripper moves up and down relative to the fixed rod sheet automatic gripper, which can form a movable clamping action on the sheet . The present invention uses a mechanical arm with a laser cutting head to realize three-dimensional laser cutting, and in order to facilitate cutting of the plate, the plate is three-dimensionally clamped, so that the laser cutting head performs a relatively small laser cutting action on the vertical surface, which can effectively improve Cutting precision.

Description

technical field [0001] The invention relates to the technical field of three-dimensional laser cutting of plates, in particular to a three-dimensional laser cutting robot for plates. Background technique [0002] Laser cutting is the use of a focused high-power-density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reached the ignition point, and at the same time the molten material is blown away by the high-speed airflow coaxial with the beam, so as to realize the cutting of the workpiece. open. Among them, the fiber laser cutting technology is growing day by day. Our company has conducted research on this technology and found that when the current fiber laser cutting machine is used for both plates and tubes, one is that the mechanical arm with a laser cutting head performs horizontal cutting on the plate. Laser cutting processing, the other is the machine tool laser cutting machine, the laser cutting head c...

Problems solved by technology

[0003] The technicians of our company mainly found the following two problems: first, due to the flat laying method, the occupied area is large, and it is easy to waste the factory space; For the raised or concave part, the laser cutting head needs to move with a cantilever, which is prone to large errors due to the movement in the form of a large cantilever, which affects the accuracy of the cutting processing position. If the plate and pipe are clamped vertically, Then the laser cutting head can make a relatively small laser cutting action on the vertical surface, which can effectively improve the cutting precision
