Description

Technical Field

[0001] This utility model relates to the field of laser cutting machines, and in particular to a high-precision double-sided positioning laser cutting machine. Background Technology

[0002] A laser cutting machine is a precision machining device that uses a high-energy-density laser beam to cut materials. Its working principle is based on the high energy density of the laser beam. The laser beam emitted by the laser is focused into a high-power-density laser beam through the optical path system and irradiates the surface of the workpiece, causing the surface of 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 kerf is eventually formed in the material, achieving the purpose of cutting.

[0003] Existing laser cutting machines typically have a worktable composed of several toothed plates. However, the tooth grooves of the toothed plates cannot be adjusted arbitrarily according to the specific dimensions of the workpiece, which may lead to poor positioning when processing parts of different sizes.

[0004] Therefore, to address the problem of poor positioning performance in existing laser cutting machines, a high-precision double-sided positioning laser cutting machine can be designed to adapt to workpieces of different sizes, making it more convenient and faster. Utility Model Content

At the same time, by setting a fixed plate, the position of all sliding plates can be adjusted simultaneously when the fixed plate is pulled, which is more convenient and faster. This solves the problem that the worktable of the existing laser cutting machine is usually composed of several toothed plates, but the tooth grooves of the toothed plates cannot be adjusted arbitrarily according to the specific size of the workpiece, which may lead to poor positioning effect when processing parts of different sizes.

One end of the sleeve is slidably connected to a slide rod, and the other end of the slide rod is connected to the bottom surface of the fixing plate.

[0010] Preferably, a waste bin is provided on the upper surface of the base plate below the fixed frame, and casters are provided at the corners of the bottom surface of the waste bin.

[0011] Preferably, the front surface of the fixed frame is provided with an equipment compartment, the right side surface of the equipment compartment is provided with a second drive motor, the output end of the second drive motor passes through the right side wall of the equipment compartment and is connected to one end of a bidirectional screw, the other end of the bidirectional screw is rotatably connected to the left side of the inner surface of the equipment compartment, and the outer surface of the bidirectional screw is threadedly connected to two symmetrical movable seats, the upper surface of the movable seats is provided with a clamping plate.

[0012] Preferably, a limiting seat is provided on the rear surface of the fixed frame, and limiting rods are connected to the left and right sides of the inner surface of the limiting seat. Two symmetrical limiting blocks are slidably connected through the outer surface of the limiting rods, and the upper surface of the limiting blocks is connected to the bottom surface of the corresponding clamping plate.

[0013] Preferably, the front and rear surfaces of the movable seat are rotatably connected to the front and rear surfaces of the inner surface of the equipment compartment.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a sliding plate, the relative distance between the first and second grooves can be adjusted when the sliding plate is pulled, thereby adjusting the spacing of the groove formed by the first and second grooves to adapt to workpieces of different sizes. At the same time, by setting a fixed plate, the position of all sliding plates can be adjusted simultaneously when the fixed plate is pulled, which is more convenient and faster.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a high-precision double-sided positioning laser cutting machine, including a base plate 1; it also includes a fixed shell 4, a first groove 5, a sliding plate 6, a second groove 7, and a fixed plate 8. A fixed frame 2 is connected to the upper surface of the base plate 1 via a support base. A laser cutting module 3 is disposed on the left side surface of the fixed frame 2. Several equally spaced fixed shells 4 are connected to the left and right sides of the inner surface of the fixed frame 2. Several equally spaced first grooves 5 are formed on the upper surface of the fixed shell 4. A sliding plate 6 is slidably inserted into the right side surface of the fixed shell 4. Several equally spaced second grooves 7 are formed on the upper surface of the sliding plate 6. The right end of the sliding plate 6 penetrates the right side wall of the fixed frame 2. With a fixed plate 8 and a sliding plate 6, the relative distance between the first groove 5 and the second groove 7 can be adjusted when the sliding plate 6 is pulled, thereby adjusting the spacing of the groove formed by the first groove 5 and the second groove 7 to adapt to workpieces of different sizes. At the same time, with the fixed plate 8, the position of all sliding plates 6 can be adjusted simultaneously when the fixed plate 8 is pulled, which is more convenient and faster. This solves the problem that the worktable of existing laser cutting machines is usually composed of several toothed plates, but the tooth grooves of the toothed plates cannot be arbitrarily adjusted according to the specific size of the workpiece, which may lead to poor positioning effect when processing parts of different sizes.

[0023] Please see Figures 1-3 In this embodiment, a mounting plate 9 is provided on the right side of the bottom surface of the fixed frame 2, and a first drive motor 10 is provided on the rear surface of the mounting plate 9. A gear 11 is provided at the output end of the first drive motor 10, and a rack 12 is provided on the bottom surface of the fixed plate 8. The gear 11 meshes with the rack 12. By providing the first drive motor 10, its output end will drive the gear 11 to rotate during operation. When the gear 11 rotates, it will drive the rack 12 to move left and right, thereby driving the fixed plate 8 to move, so as to adjust the position of the sliding plate 6. Two symmetrical fixed seats 13 are provided on the left side of the bottom surface of the fixed frame 2, and the right side of the fixed seat 13 is... A sleeve 14 is provided on the surface of the fixed plate 8. One end of a sliding rod 15 is inserted and slidably connected to the right surface of the sleeve 14. The other end of the sliding rod 15 is connected to the bottom surface of the fixed plate 8. By setting the sleeve 14 and the sliding rod 15, when the fixed plate 8 moves, the sliding rod 15 will slide synchronously inside the sleeve 14, thereby improving the stability of the movement of the fixed plate 8. A waste bin 16 is provided on the upper surface of the base plate 1 below the fixed frame 2. Universal wheels 17 are provided at the corners of the bottom surface of the waste bin 16. By setting the waste bin 16, processing chips and waste materials can be collected, and the universal wheels 17 make it easy for workers to move the waste bin 16, improving convenience.

[0024] Please see Figures 1-4In this embodiment, a device compartment 18 is provided on the front surface of the fixed frame 2, and a second drive motor 19 is provided on the right side surface of the device compartment 18. The output end of the second drive motor 19 passes through the right side wall of the device compartment 18 and is connected to one end of a bidirectional screw 20. The other end of the bidirectional screw 20 is rotatably connected to the left side of the inner surface of the device compartment 18. Two symmetrical movable seats 21 are threadedly connected to the outer surface of the bidirectional screw 20. A clamping plate 22 is provided on the upper surface of the movable seats 21. By providing the second drive motor 19, its output end can drive the bidirectional screw 20 to rotate during operation. When the bidirectional screw 20 rotates, it can drive the two movable seats 21 that are threadedly engaged with it to move in opposite directions, thereby driving the clamping plate 22 to clamp the workpiece in both directions, thereby improving the processing accuracy. A limit switch is provided on the rear surface of the fixed frame 2. The inner surface of the seat 23 is connected to the left and right sides of the limiting seat 23 with limiting rods 24. The outer surface of the limiting rods 24 is slidably connected to two symmetrical limiting blocks 25. The upper surface of the limiting blocks 25 is connected to the bottom surface of the corresponding clamping plate 22. By setting the limiting rods 24 and limiting blocks 25, when the clamping plate 22 moves, it will drive the limiting blocks 25 to slide synchronously on the outer surface of the limiting rods 24. The limiting rods 24 will restrict the sliding direction of the limiting blocks 25, thereby improving the stability of the movement of the clamping plate 22. The front and rear surfaces of the moving seat 21 are rotatably connected to the front and rear surfaces of the inner surface of the equipment compartment 18. By fitting the moving seat 21 with the equipment compartment 18, the equipment compartment 18 can limit the moving seat 21, avoiding the problem of the bidirectional screw 20 causing the moving seat 21 to rotate when it rotates, which would lead to a decrease in transmission efficiency.

[0025] During operation, the first drive motor 10 drives the gear 11 to rotate. The rotating gear 11 drives the meshing rack 12 to move left and right, thereby moving the fixed plate 8 and adjusting the position of the sliding plate 6. The sleeve 14 and slide rod 15 ensure that the slide rod 15 slides synchronously within the sleeve 14 as the fixed plate 8 moves, improving the stability of the fixed plate 8's movement. The waste bin 16 collects processing debris and waste, and the casters 17 facilitate movement by the operator, enhancing convenience. The second drive motor 19, during operation, outputs… The end can drive the bidirectional screw 20 to rotate. When the bidirectional screw 20 rotates, it can drive the two moving seats 21 that are threaded with it to move in opposite directions, thereby driving the clamping plate 22 to clamp the workpiece in both directions, thereby improving the machining accuracy. By setting the limiting rod 24 and the limiting block 25, when the clamping plate 22 moves, it will drive the limiting block 25 to slide synchronously on the outer surface of the limiting rod 24. The limiting rod 24 will restrict the sliding direction of the limiting block 25, thereby improving the stability of the movement of the clamping plate 22. By fitting the moving seat 21 with the equipment compartment 18, the equipment compartment 18 can limit the moving seat 21, avoiding the problem of the bidirectional screw 20 driving the moving seat 21 to rotate when it rotates, which would lead to a decrease in transmission efficiency.

[0026] Through the above steps, by setting the sliding plate 6, the relative distance between the first groove 5 and the second groove 7 can be adjusted when the sliding plate 6 is pulled, thereby adjusting the spacing of the groove formed by the first groove 5 and the second groove 7 to adapt to workpieces of different sizes. At the same time, by setting the fixed plate 8, the position of all the sliding plates 6 can be adjusted simultaneously when the fixed plate 8 is pulled, which is more convenient and faster. This solves the problem that the worktable of the existing laser cutting machine is usually composed of several toothed plates, but the tooth grooves of the toothed plates cannot be arbitrarily adjusted according to the specific size of the workpiece, which may lead to poor positioning effect when processing parts of different sizes.
