Description

Technical Field

[0001] The utility model relates to the technical field of fiber laser cutting machines, and particularly relates to a loading device for fiber laser cutting. Background Technique

[0002] A fiber laser is a newly developed type of fiber laser internationally. It outputs a laser beam with a high energy density and focuses it on the surface of the workpiece, causing the area of the workpiece irradiated by the ultra-fine focal spot to instantaneously melt and vaporize. Automatic cutting is achieved by moving the position of the spot irradiation through a numerical control mechanical system.

[0003] In the existing fiber laser cutting machines, manual feeding is usually adopted, which is rather troublesome. Therefore, some people think of setting a feeding carrier plate on the equipment to realize material pushing. For example, the Chinese utility model patent with the publication number CN215787439U specifically discloses a feeding mechanism of a fiber laser cutting machine.

[0004] However, people will find in the actual use process that the feeding structure used in the above-mentioned fiber laser cutting machine is that during use, the material needs to be placed on the feeding carrier plate, and then the material is pushed through the feeding carrier plate. However, the material is not restricted on the feeding carrier plate, which leads to the phenomenon that the position of the material is easily offset during the loading process. Once the position of the material is offset, it will directly affect the normal cutting operation of the cutting machine, greatly reducing its practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a loading device for fiber laser cutting to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A loading device for fiber laser cutting, including a bottom plate, a first slideway, a second slideway and a support table. The first slideway and the second slideway are symmetrically arranged above the bottom plate. A first slider is slidably connected in the first slideway, and a second slider is slidably connected in the second slideway. A lead screw passes through the first slider, and the lead screw is threadedly connected to the first slider. The lead screw is parallel to the first slideway, and the end of the lead screw is rotatably connected to the first slider. A first driving motor is arranged at the end of the first slideway, and the driving shaft of the first driving motor is connected to the lead screw;

[0007] The support platform is arranged between the first slideway and the second slideway, and the support platform is fixed to the first slider and the second slider. A loading platform is fixed on one side of the support platform, and an L-shaped plate is fixed on the other side of the support platform. A second driving motor is arranged on the L-shaped plate, and a gear is connected to the driving shaft of the second driving motor. Above the support platform, two chutes are symmetrically opened on the side of the gear. A first rack and a second rack are respectively slidably connected in the two chutes. Both the first rack and the second rack are meshed with the gear. A first clamping plate perpendicular to each other is arranged at the end of the first rack, and a second clamping plate perpendicular to each other is arranged at the end of the second rack. In this application, by placing the material on the loading platform, the second driving motor can be used to drive the gear to rotate, thereby pushing the first rack and the second rack to slide in the chutes, and at the same time driving the first clamping plate and the second clamping plate to approach the material and clamp it, so as to restrict the material. The first driving motor is used to drive the screw rod to rotate, thereby driving the first slider to move, and then driving the loading platform to feed.

[0008] Preferably, a plurality of slide rails are arranged on the upper surface of the bottom plate, and the support platform is slidably connected to the slide rails. The arrangement of the slide rails improves the stability of sliding.

[0009] Preferably, a frame is arranged above the bottom plate near the first slideway and the second slideway. The arranged frame is used to install the fiber laser cutting machine, and the material is sent below the frame for laser cutting operation.

[0010] Preferably, rubber pads are arranged on the surfaces of the first clamping plate and the second clamping plate. The arrangement of the rubber pads can avoid hard contact between the clamping plates and the material, resulting in material damage.

[0011] Preferably, connecting plates are fixed on the sides of the first slideway and the second slideway, and the connecting plates are fixed to the bottom plate by bolts, thereby realizing the detachable installation of the first slideway and the second slideway.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In the present utility model, the material is placed on the loading platform, and then the gear is used to drive the rack to move, thereby driving the clamping plate to clamp and restrict the material. Then, the first driving motor can be used to drive the screw rod to rotate, and the screw rod is used to drive the first slider to move, thereby driving the loading platform to move by the first slider and pushing the loading platform forward, so as to realize feeding. Since the material is clamped and restricted by the clamping plate during the process, the phenomenon of material position deviation is effectively avoided, and the subsequent fiber laser cutting operation is not affected due to the deviation of the material, improving the practicability of the device.

[0022] The support platform 4 is arranged between the first slideway 2 and the second slideway 3, and the support platform 4 is fixed to the first slider 201 and the second slider 301. A loading platform 5 is fixed on one side of the support platform 4, and an L-shaped plate 401 is fixed on the other side of the support platform 4. A second driving motor 402 is arranged on the L-shaped plate 401, and the driving shaft of the second driving motor 402 is connected with a gear 403.
