Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a bed structure for a laser cutting machine and a laser cutting machine. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, 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 kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] In existing laser cutting machines, the metal sheet is placed directly on the worktable. Because it is placed directly, the metal sheet will be tilted. When the laid-out data is laser cut, it will cause the product to have missing corners, increasing the scrap rate of processing and production and causing material waste. Utility Model Content

[0004] To address this issue, this invention provides a bed structure for a laser cutting machine and a laser cutting machine in general. By using a plate alignment component, the problem is solved where the position of the metal plate tilts due to direct placement, which can lead to corner defects in the product when the laid-out data is laser-cut.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bed structure for a laser cutting machine, comprising a laser cutting machine bed, a laser cutting device and a laser cutting platform at the top of the laser cutting machine bed, multiple plate support racks fixedly installed inside the laser cutting platform, and a plate alignment component at the bottom of the laser cutting machine bed. The plate alignment component includes a fixing frame, with horizontal grooves on both sides of the fixing frame and oblique grooves at both ends of the two horizontal grooves. A bidirectional lead screw is inserted inside the fixing frame, and two alignment units are sleeved on the outside of the bidirectional lead screw. Each alignment unit includes a threaded block, and a connecting plate is sleeved on the outside of the threaded block. A sliding groove is opened inside the connecting plate, connecting posts are fixedly installed on both sides of the connecting plate, and a connecting strip is fixedly installed on the top of the connecting plate. Multiple fixing posts are fixedly installed on the top of the connecting strip.

[0006] Preferably, the top of the fixed frame is fixedly connected to the bottom of the laser cutting machine bed, a motor is fixedly installed on one side of the fixed frame, and the output end of the motor is fixedly connected to one end of the bidirectional lead screw.

[0007] Preferably, the two ends of the bidirectional lead screw pass through the two side walls of the fixed frame and are connected to both side walls of the fixed frame via bearings.

[0008] Preferably, the threads at both ends of the bidirectional lead screw have opposite directions of rotation, and the bidirectional lead screw passes through the threaded block and is connected to the threaded block by threads.

[0009] Preferably, the threaded block is disposed inside the slide groove and is slidably connected to the slide groove.

[0010] Preferably, the connecting post extends into the inclined groove and is slidably connected to the inclined groove.

[0011] Preferably, the top of the fixing column extends into the interior of the plate support rack.

[0012] This utility model also provides a laser cutting machine, which includes the bed structure described above.

[0013] The present invention has the following advantages:

[0014] 1. The two threaded blocks are driven to move relative to each other towards the center by the double-acting screw. The movement of the threaded blocks drives the connecting plate to move by cooperating with the shape of the slide groove. When the connecting plate moves, it moves upward by cooperating with the connecting column and the inclined groove and the transverse groove, so that the connecting plate moves synchronously and the two fixed columns work at the same time, which makes it easy to straighten the top plate of the plate support rack.

[0015] 2. As the connecting plate moves upward, the connecting strip causes the fixing column to extend out of the top of the plate support rack and move laterally at the top of the plate support rack. This allows the fixing columns extending from both sides to clamp and straighten the plate placed on top of the plate support rack, preventing the plate from tilting and thus improving the accuracy of plate cutting.

A connecting plate 57 is sleeved on the outside of the threaded block 56. A sliding groove 58 is provided inside the connecting plate 57. Connecting posts 59 are fixed on both sides of the connecting plate 57. A connecting strip 60 is fixed on the top of the connecting plate 57. Multiple fixing posts 61 are fixed on the top of the connecting strip 60.

[0025] In this embodiment, in order to align the plate placed on top of the laser cutting platform 3, the two threaded blocks 56 are moved relative to each other towards the center by the bidirectional lead screw 55. The movement of the threaded blocks 56 drives the connecting plate 57 to move by cooperating with the shape of the slide groove 58. When the connecting plate 57 moves, it moves upward by cooperating with the connecting column 59, the inclined groove 53, and the transverse groove 52. Then, the connecting strip 60 causes the fixing column 61 to extend out of the top of the plate support rack 4 and move laterally on the top of the plate support rack 4. Thus, the fixing columns 61 extending from both sides clamp and align the plate placed on top of the plate support rack 4, preventing the plate from being placed crooked, thereby improving the accuracy of plate cutting.

[0026] In order to achieve the purpose of the two threaded blocks 56 driving the connecting plate 57 to move relative to each other, the device adopts the following technical solution: the top of the fixed frame 51 is fixedly connected to the bottom of the laser cutting machine bed 1, a motor 54 is fixedly installed on one side of the fixed frame 51, the output end of the motor 54 is fixedly connected to one end of the bidirectional lead screw 55, the two ends of the bidirectional lead screw 55 pass through the two side walls of the fixed frame 51 and are connected to the two side walls of the fixed frame 51 through bearings, the two ends of the bidirectional lead screw 55 have opposite threads, the bidirectional lead screw 55 passes through the threaded block 56 and is connected to the threaded block 56 through threads, the plate is placed on the top of the plate support rack 4, the motor 54 is started to rotate forward, the rotation of the motor 54 drives the two threaded blocks 56 to move relative to each other towards the center through the bidirectional lead screw 55, and the movement of the threaded blocks 56 drives the connecting plate 57 to move through the cooperation with the shape of the slide groove 58;

[0027] To achieve the purpose of the fixed column 61 extending out of the top of the plate support rack 4 and moving laterally, the device adopts the following technical solution: the threaded block 56 is located inside the slide groove 58 and is slidably connected to the slide groove 58; the connecting column 59 extends into the inclined groove 53 and is slidably connected to the inclined groove 53; the top of the fixed column 61 extends into the plate support rack 4; when the connecting plate 57 moves, the connecting column 59 cooperates with the inclined groove 53 and the transverse groove 52, so that the connecting plate 57 moves upward while moving, and then the fixed column 61 extends out of the top of the plate support rack 4 through the connecting strip 60 and moves laterally on the top of the plate support rack 4, so that the plate placed on the top of the plate support rack 4 is clamped and aligned by the fixed columns 61 extending from both sides.

[0028] The usage process of this utility model is as follows: When using this utility model, connect an external power source. When it is necessary to straighten the plate, place the plate on top of the plate support rack 4, start the motor 54 to rotate forward. The rotation of the motor 54 drives the two threaded blocks 56 to move relative to each other towards the center through the bidirectional lead screw 55. The movement of the threaded blocks 56 drives the connecting plate 57 to move through the cooperation with the shape of the slide groove 58. When the connecting plate 57 moves, it moves upward through the cooperation of the connecting post 59 with the inclined groove 53 and the transverse groove 52. Then, through the connecting strip 60, the fixing post 61 extends out of the top of the plate support rack 4 and moves laterally on the top of the plate support rack 4. Thus, the fixing posts 61 extending from both sides clamp and straighten the plate placed on the top of the plate support rack 4, preventing the plate from being placed crooked, thereby improving the accuracy of plate cutting.

[0029] This utility model also provides a laser cutting machine, which includes the above-described bed structure.
