Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laser cutting, and more specifically relates to a robot precision laser cutting tool. Background Art
[0002] Laser cutting robots are advanced equipment that combines laser technology and robotics technology for automated and high-precision material cutting. They are widely used in industrial manufacturing, automobile manufacturing, aerospace, electronic equipment manufacturing and other fields.
[0003] The solution commonly adopted by existing laser cutting robots is to directly install the laser cutting head on the sixth axis of the robot and cut the workpiece through the movement of the robot.
[0004] Existing laser cutting robots have the following disadvantages: Since the robot uses a handheld laser cutting head for direct cutting, although the robot's repeated positioning accuracy is relatively good, there is still a large error relative to the absolute accuracy, especially when cutting more precisely and requiring graphics with a smaller tolerance size band, there is still a problem of insufficient cutting accuracy. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a robot precision laser cutting tool, which realizes the cutting of various cutting lines on a plane through two linear modules, and can cut products at high speed and precision.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a robot precision laser cutting tool, comprising a base installed on the sixth axis of the robot, two linear modules are arranged on the base, and the two linear modules are perpendicular to each other in the moving direction, a guide block is arranged on the linear module, a linear guide is slidably connected to the guide block, a laser head mounting plate is arranged between the two linear guides, and a laser cutting head is arranged on the laser head mounting plate.
[0007] Furthermore, the base includes a connecting plate, and two coplanar and mutually perpendicular supporting plates are arranged at the bottom of the connecting plate, and the supporting plate and the connecting plate are mutually perpendicular, and the two linear modules are respectively located on the two supporting plates.
[0008] Furthermore, the two linear guide rails are respectively connected to two adjacent sides of the laser head mounting plate, and the laser cutting head is located on one side of the laser head mounting plate close to the connecting plate.
[0009] Furthermore, a guide rail mounting plate is provided between the guide rail block and the linear module.
[0010] Compared with the prior art, the beneficial effects of the utility model are: during laser cutting, the base is first moved to the top of the graphic surface to be cut by the robot, and the plane formed by the two guide rails is parallel to the cutting graphic surface, and then the laser cutting head is driven to move by the two linear die bases, that is, when one of the linear modules moves, it will drive the linear guide rail on the other linear module to slide on the guide rail block, and the two linear guide rails can move at the same time to realize the cutting of various cutting lines on the plane, thereby realizing high-speed and precise cutting of the product.

In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.
[0015] Reference Figure 1 The utility model is further described.
[0016] A robot precision laser cutting tool comprises a base installed on the sixth axis of the robot, wherein the base is provided with two linear modules 1, and the two linear modules 1 are perpendicular to each other in the moving direction, the linear modules 1 are provided with a guide block 2, a linear guide 3 is slidably connected to the guide block 2, a laser head mounting plate 4 is provided between the two linear guides 3, and a laser cutting head 5 is provided on the laser head mounting plate 4.
[0017] Preferably, in this embodiment, the linear module 1 is a ball screw structure with no return clearance and high movement accuracy.
[0018] like Figure 1 As shown, in this embodiment, preferably, the base includes a connecting plate 6, and two coplanar and mutually perpendicular supporting plates 7 are arranged at the bottom of the connecting plate 6, and the supporting plates 7 are perpendicular to the connecting plate 6, and the two linear modules 1 are respectively located on the two supporting plates 7.

[0021] like Figure 1 As shown, during laser cutting, the robot first moves the base to the top of the graphic surface to be cut, and makes the plane formed by the two guide rails parallel to the cutting graphic surface, and then drives the laser cutting head 5 to move through the two linear die bases, that is, when one of the linear modules 1 moves, it will drive the linear guide 3 on the other linear module 1 to slide on the guide block 2, and the two linear guides 3 can move at the same time to realize the cutting of various cutting lines on the plane, thereby realizing high-speed and accurate cutting of the product.
[0022] In addition, since the mass of the laser cutting head 5 is borne by two linear modules 1 at the same time, the load of the linear module 1 is small and balanced, and the power of the linear module 1 is reduced, the energy consumption is reduced, and the effect of energy saving and emission reduction is achieved.
