Description

TECHNICAL FIELD

[0001] The utility model relates to laser cutting machine technical field especially relates to a positioning device of laser cutting machine. BACKGROUND

[0002] When cutting plate material by laser, the laser will continue to release energy downward after penetrating the plate material, in order to reduce or avoid the laser cutting the cutting platform, the existing cutting platform generally uses serrated strip plate as support. The conventional serrated platform lacks a positioning device for fixing the plate material, in CN221389462U, a plate material positioning device of laser cutting machine is disclosed, which drives the clamp to move by setting a lead screw between adjacent serrated plates, so as to fix the plate material. But since the lead screw is exposed outside like the serrated plate, lacking a protection device, the lead screw may also be damaged after the laser penetrates the plate material, which needs to be improved. SUMMARY

[0003] In order to solve the problems mentioned in the background art, the purpose of the utility model is to provide a positioning device of laser cutting machine.

[0004] In order to achieve the above-mentioned target, the technical scheme of the utility model is as follows:

[0005] A positioning device of laser cutting machine, comprising a rectangular frame, the frame is horizontally arranged, a plurality of serrated plates with sawtooth-shaped top are fixedly connected between the two long sides of the frame, a downward extending side plate is fixedly connected on each long side of the frame, a bidirectional lead screw is installed between the two side plates, a motor for driving the bidirectional lead screw to rotate is installed on one of the side plates, two rectangular moving frames parallel to the side plates and moving frames are movably arranged between the two side plates, the bottom edges of the two moving frames are respectively threadedly connected to the two opposite threaded segments of the bidirectional lead screw, a plurality of guide rods are fixedly connected between the two side plates, the top edges of the two moving frames are sleeved on the plurality of guide rods, a plurality of longitudinal abutting rods are arranged at intervals on the top of the moving frame, the plurality of abutting rods are arranged alternately with the plurality of serrated plates, a baffle is fixedly connected between the two side plates, the baffle passes through the two moving frames and blocks the lead screw.

[0006] Further, the lead screw is parallel to the baffle, and the baffle is arranged obliquely.

[0007] The utility model has the advantages that the bidirectional lead screw can drive the two moving frames to move synchronously in opposite directions or in the same direction, so that the abutting rods can clamp the plate material placed on the plurality of serrated plates, and the positioning effect is achieved, and the lead screw is blocked by the baffle, so that the lead screw can be effectively protected from being damaged by the laser, and the durability of the lead screw is ensured.
