Description

Technical Field

[0001] The utility model relates to the technical field of laser tube cutting, in particular to a double-station laser tube cutting machine. Background Art

[0002] Laser pipe cutting machine is a professional pipe laser cutting equipment with high integration and linkage CNC functions.

[0003] A laser beam is used to form a thin line on the surface of the tube, and the tube is cut by moving the laser head. This method not only cuts quickly and accurately, but also allows for cutting of various shapes, such as circles, squares, and ovals, greatly improving the flexibility and efficiency of tube processing.

[0004] Laser tube cutting machines are mainly divided into two types: fixed-material cutting type laser tube cutting machines and feed-material cutting type laser tube cutting machines.

[0005] Laser tube cutting machines are widely used in various manufacturing and processing industries such as sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, grain machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal external processing, kitchenware processing, etc.

[0006] It can cut a variety of metal plates and pipes, and is mainly suitable for fast cutting of stainless steel, carbon steel, manganese steel, copper plates, aluminum plates, galvanized plates, various alloy plates, rare metals and other materials.

[0007] At present, the common laser tube cutting machines on the market often have a laser cutting head that can only cut the tubes on one workstation. After the tube is cut, workers need to remove it and replace it with a new tube. During this period, the laser tube cutting machine is in a stopped state and its working efficiency is low.

[0008] Therefore, the present application provides a dual-station laser tube cutting machine to overcome the defects of the prior art. Utility Model Content

[0009] The utility model aims to solve the problem of low working efficiency of the existing laser tube cutting machine.

[0010] This utility model provides a double-station laser tube cutting machine with sophisticated design and efficient processing capabilities. The machine mainly consists of a bed, a moving mechanism, a laser cutting head, a protective cover box, a chuck cover box and a rotating mechanism.

[0011] A slide rail and a rack are fixedly installed on the top of the bed.

[0012] The moving mechanism is connected to the bed through a sliding block 1 on the gantry. Motor 2 inside the gantry drives gear 1, which meshes with rack 1, achieving horizontal movement. A cylinder at the top of the gantry drives the connecting box to slide horizontally along slide rail 2. Motor 3 inside the connecting box, through a gear, meshes with rack 2 on the connecting column, driving the connecting column up and down. A connecting plate is installed on one side of the connecting column, and motor 1 is mounted on the connecting plate to rotate the laser cutting head.

[0013] The protective cover box is located at one end of the bed and is fixed to the bed via the protective cover base. The rotating mechanism within it consists of a fixed box, motor five, gear three, gear four, a rotating shaft, a transmission shaft, sleeve two, and a clamping piece. The chuck cover box is located at the other end of the bed and is slidably connected to slide rail one via slider two. Motor four within it drives gear two to engage with rack one, achieving longitudinal movement. The rotating mechanisms in the chuck cover box and the protective cover box are structurally identical. The bottom of the fixed box is fixedly connected to bracket one or bracket two. Motor five drives gear four through gear three, which in turn drives the transmission shaft and sleeve two. The clamping piece on sleeve two is used to secure the workpiece.

[0014] The side of the sleeve is equipped with a cross-shaped slot containing four clips, which are installed in the horizontal and vertical slots respectively. The clips consist of a slider, a bolt, a connecting block, and a clip. The slider slides in the slot, and the bolt passes through the connecting hole to secure it to the slider. The connecting block and clip are used to fix the workpiece.

[0015] The beneficial effects of the utility model are as follows: the double-station laser tube cutting machine provided by the utility model can drive the laser cutting head to move in three dimensions: front and back, left and right, and up and down, by setting a moving mechanism, and can drive the laser cutting head to rotate, so as to facilitate multi-angle processing of tubes, so that it can meet various processing needs of customers;

[0016] By arranging a protective cover box containing a rotating mechanism and a chuck cover box containing a rotating mechanism on both sides of the moving mechanism, the device can work continuously. After cutting one pipe, it can immediately cut another pipe, which improves the work efficiency and makes it safer for workers to replace pipes.

[0017] By setting a chuck cover box that is slidably connected to the bed, the device can adjust the distance between the moving mechanism, the protective cover box and the chuck cover box according to the specific situation when processing pipes of different lengths, so that it can better process different pipes;

[0018] By setting up a rotating mechanism driven by motor five, motor five can drive the transmission shaft and sleeve two to rotate through gears. By setting four slidingly connected clamping parts on the surface of sleeve two, the four clamping parts can adjust the distance between each other by sliding on the surface of sleeve two, so that different types of pipes can be clamped. The four clamping parts work together to clamp the pipes. Since a connecting hole is opened on the clamping part, the clamping part can be fixed to the surface of sleeve two by bolts to prevent the clamping part from sliding during processing.
