Embodiment 1

[0029] see Figure 1 to Figure 4 , the embodiment of the present invention provides an anti-collision protection device for a cutting head, which includes an upper protection part 1 arranged at the lower end of the upper part 4 of the cutting head and a lower protection part 2 arranged at the upper end of the lower part 5 of the cutting head. The protection part 1 and the lower protection part 2 are connected through a magnetic attraction connection structure, and the upper part 4 of the cutting head is connected with the lower part 5 of the cutting head. When the lower end surface of the protection part 1 and the upper end surface of the lower protection part 2 are attracted by the magnetic force connection structure, the optical path through hole 17 of the upper protection part communicates with the optical path through hole 26 of the lower protection part.

[0030] The optical path through hole 17 of the upper protection part communicates with the optical path through hole ...

Embodiment 2

[0052] see Figure 1 to Figure 4 , this embodiment also discloses a laser cutting head, including the upper part 4 of the cutting head, the lower part 5 of the cutting head and the anti-collision protection device as described in Embodiment 1, wherein the upper protection part of the anti-collision protection device 1 Set the lower end of the upper part 4 of the cutting head, the lower protection part 2 of the anti-collision protection device is arranged on the upper end of the lower part 5 of the cutting head, between the upper protection part 1 and the lower protection part 2 of the anti-collision protection device or the cutting head A connector is connected between the upper part 4 and the lower part 5 of the cutting head, and is used to pull the lower protecting part 2 and the lower part 5 of the cutting head when the upper protecting part 1 and the lower protecting part 2 are separated.

[0053] Furthermore, the connector can be deformed when stressed, and can return to ...

Abstract

The invention relates to a laser cutting head and an anti-collision protection device of the cutting head. The anti-collision protection device comprises an upper protection part arranged at the lower end of an upper part of the cutting head and a lower protection part arranged at the upper end of a lower part of the cutting head, wherein the upper protection part and the lower protection part are connected with each other through a magnetic attraction connection structure; positioning pins are arranged on one of opposite surfaces of the upper protection part and the lower protection part; positioning holes matched with the positioning pins are formed in the other opposite surface, so that a repeated positioning structure is formed; when collision occurs, the anti-collision protection device enables a collision part of the cutting head to be separated from other parts; the problem that the cutting head is damaged due to the acting force generated by collision is relieved; meanwhile, a signal is sent to enable the cutting machine to stop running, power-off protection is formed, and dual protection of a mechanical structure part and a circuit part is achieved; the damage to the collision part of the three-dimensional cutting head is reduced; the repeated dimming work of an operator is avoided; the cost can be effectively saved; and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of laser cutting, and in particular relates to a laser cutting head and an anti-collision protection device for the cutting head. Background technique [0002] Nowadays, laser cutting technology has been widely used in various fields including automobiles and aerospace. In addition to cutting plates and pipes, the demand for cutting three-dimensional parts with complex curved surface structures is gradually increasing. [0003] The existing technology uses a three-dimensional cutting head to realize five-axis linkage on the basis of a traditional laser cutting machine. In the process of cutting complex three-dimensional parts, in order to keep the laser path perpendicular to the processing surface, the cutting head may collide with the surface of the workpiece or fixture, causing damage to the cutting head. Contents of the invention [0004] The purpose of the present invention is to overcome the defects ...
