Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a limiting mechanism of a laser cutting head. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting.

[0004] During implementation, the above patent document can cooperate with the clamping plate to improve the stability of the plate tube and prevent misalignment between multiple plate tubes. However, it cannot adjust the cutting position of the laser cutting machine in multiple directions, resulting in certain limitations on the cutting position of the workpiece by the laser cutting machine. As a result, the workpiece needs to be shifted multiple times and then cut again by the laser cutting machine, which reduces work efficiency. Utility Model Content

The front and rear ends of the outer surface of the supporting seat 2 are symmetrically threaded with a driving mechanism 3, which can push the corresponding clamping mechanisms 4 to approach each other.

The left and right sides of the upper end of the outer surface of the lower pad 1 are fixedly connected to a supporting plate 2 5. A plurality of through holes 51 communicating with the outside world are spaced apart on the upper left and right ends of the outer surface of the supporting plate 2 5.

An electric telescopic rod 6 is fixedly connected to the middle of the upper end of the outer surface of the support plate 5. The output end of the piston rod at the lower part of the electric telescopic rod 6 is fixedly connected to a magnetic mechanism 7, which can limit and fix the position of the laser cutting head 103 when the external force is removed. The left and right parts of the magnetic mechanism 7 are symmetrically and movably connected with a locking mechanism 8, which can lock the position of the magnetic mechanism 7 that is adjusted to the required height. The lower part of the magnetic mechanism 7 is fixedly connected with a guide mechanism 9, which can enable the laser cutting head 103 to adjust the cutting position of the workpiece in multiple directions. The lower part of the guide mechanism 9 is slidably connected with a cutting mechanism 10, which can cut the workpiece.

[0024] In order to achieve the purpose of pushing the corresponding clamping mechanisms 4 closer to each other, refer to Figure 2 The driving mechanism 3 includes a threaded rod 31, which can drive the toothed support plate 43 connected thereto to slide toward the middle of the inner cavity of the bearing seat 2.

The four T-shaped blocks 73 are slidably connected to the corresponding T-shaped slots 52.

[0027] When the operator removes the force for adjusting the position of the laser cutting head 103 and needs to cut the workpiece, the laser cutting head 103 can be stably fixed in the adjusted position under the magnetic attraction of the magnet 72 on the circular iron block 101, and will not shift when cutting the workpiece.
