Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically relating to a long-stroke slide for a laser cutting machine. Background Technology

[0002] A laser cutting machine is a precision device that uses a high-energy-density laser beam for material processing. Its core principle involves generating a high-power laser beam through a laser generator, which is then focused into a tiny spot via an optical fiber transmission system and optical components. This spot locally heats and melts or vaporizes the material, while coaxial high-pressure gas blows away the molten material, ultimately achieving precise cutting. A suitable long-stroke slide is required when using a laser cutting machine.

[0003] While the long-stroke slide used in existing laser cutting machines can adjust the position of the laser cutting machine, it cannot handle certain sparks or debris generated during actual use. These sparks or debris can easily injure nearby operators, thus posing a certain safety hazard to the device and making it unsuitable for use.

[0004] Therefore, a long-stroke slide for laser cutting machines is needed to solve the problem in existing technologies that cannot handle certain sparks or debris generated during cutting, which could easily cause injury to nearby operators. Utility Model Content

[0005] The purpose of this invention is to provide a long-stroke slide for a laser cutting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a long-stroke slide for a laser cutting machine, comprising a slide plate, toothed seats disposed at both ends of the bottom of the inner surface of the slide plate, a limiting block slidably inserted at the middle position of the slide plate, and a laser cutter disposed at the bottom of the limiting block, characterized in that: it further comprises a movable protective mechanism acting on the laser cutter, wherein the slide plate and the two toothed seats are slidably connected at their ends that are far apart from each other;

[0007] The active protective mechanism includes a barrier component and a moving component.

[0008] It should be noted in the solution that the moving component includes a first motor fixed to the bottom of one end of each of the two slides away from each other, a first spur gear fixedly sleeved on the output end of the first motor, a second motor fixed to the top of one end of one of the slides, a threaded rod fixed to the output end of the second motor, a threaded seat threadedly connected to the middle position of the outer circumference of the threaded rod, and a support rod fixed to the bottom of the threaded seat.

[0009] It is further worth noting that the bottom of the support rod passes through the limiting block and is fixed to the surface of the top of the laser cutter. The first spur gear is meshed with the adjacent gear seat. The output end of the first motor is rotatably connected to the inner wall of the slide plate. The threaded rod is rotatably connected to the inner wall and one end of the inner surface of one side of the slide plate.

[0010] Furthermore, it should be noted that the blocking assembly includes a movable shaft rotatably connected to the inner surface of the slide plate at the top of the threaded rod, a second spur gear fixedly sleeved on one end of the outer circumferential surface of the threaded rod and the movable shaft, a rotating shaft rotatably connected to one end of the threaded seat, a pulley sleeved on one end of the outer circumferential surface of the rotating shaft and at the middle position of the outer circumferential surface of the movable shaft, a limiting component acting on one of the pulleys, abutment grooves formed at both ends of the outer circumferential surface of the movable shaft, an abutment block inserted into the cavity of the abutment groove, and a connecting belt sleeved between the two pulleys.

[0011] In a preferred embodiment, the inner circumferential surfaces of the pulleys at the top adjacent positions of the abutment block are fixed, and the two second spur gears are meshed together, wherein the inner wall of one of the pulleys is fixed to the outer circumferential surface of the adjacent rotating shaft.

[0012] In a preferred embodiment, the limiting component includes a limiting seat fixed to the top of the threaded seat, an annular groove formed at one end of the limiting seat, and two positioning seats slidably inserted into the annular groove. One end of the positioning seat is fixed to the surface of the adjacent pulley. The cross-section of the inner cavity of the annular groove is T-shaped, and the cross-section of the positioning seat embedded in the inner cavity surface of the annular groove is T-shaped.

[0013] In a preferred embodiment, the barrier assembly further includes a rotating cylinder rotatably connected to the bottom of the threaded seat outside the support rod, and a bevel gear fixedly sleeved on the outer circumferential surface of the rotating cylinder and the other end of the outer circumferential surface of the rotating shaft. The two bevel gears are meshed together. The rotating cylinder is rotatably connected to the inner wall of the limiting block, and the bottom of the rotating cylinder is rotatably connected to the top surface of the laser cutter.

[0014] In a preferred embodiment, the barrier assembly further includes a sleeve plate fixedly sleeved on the outer circumferential surface of the rotating cylinder, a plurality of blocks arranged equidistantly around the bottom of the sleeve plate, and a connecting rod fixed between the sleeve plate and the blocks.

[0015] Compared with the prior art, the long-stroke slide of the laser cutting machine provided by this utility model has at least the following beneficial effects:

[0016] (1) When the laser cutter is able to move along a certain trajectory to cut by starting the second motor and the first motor, multiple blocks can wrap around the cutting position of the laser cutter and make a circular motion. This reduces the debris and sparks moving to the outside under the blocking effect of the blocks, thereby reducing the probability of the debris and sparks generated by the cutting causing injury to the operator. In addition, the multiple blocks do not completely block the cutting position of the laser cutter, making it convenient for the user to adjust the contact between the workpiece and the cutting position of the laser cutter and to observe the cutting edge during the cutting process, thereby improving the applicability of the device.

[0017] (2) By simultaneously starting the first motor and the second motor, the slide can drive the laser cutter to move horizontally in the left and right directions, while the second motor drives the threaded seat to move the laser cutter horizontally in the front and back directions, which makes it easier for the user to cut at an angle according to the actual needs of the use, thereby further improving the applicability of the device.

[0024] Please see Figure 1-5This utility model provides a long stroke slide for a laser cutting machine, including a slide plate 1, toothed seats 2 disposed at both ends of the bottom of the inner surface of the slide plate 1, a limiting block 10 slidably inserted in the middle of the slide plate 1, a laser cutter 8 disposed at the bottom of the limiting block 10, and a movable protective mechanism acting on the laser cutter 8. The slide plate 1 and the two toothed seats 2 are slidably connected at the ends that are far apart from each other.

[0025] The active protection mechanism includes barrier components and moving components;

[0026] The moving component enables the laser cutter 8 to move simultaneously in the front-back and left-right directions to perform oblique cutting. During the cutting process, the blocking component can reduce the amount of debris and sparks that move to the outside, thereby reducing the probability of damage to the operator from the debris and sparks generated during cutting.

[0027] Please see Figure 1-5 The moving component includes a first motor 3 fixed to the bottom of two slide plates 1 at opposite ends, a first spur gear 4 fixedly sleeved on the output end of the first motor 3, a second motor 5 fixed to the top of one end of one of the slide plates 1, a threaded rod 6 fixed to the output end of the second motor 5, a threaded seat 7 threadedly connected to the middle position of the outer circumference of the threaded rod 6, and a support rod 25 fixed to the bottom of the threaded seat 7. The bottom of the support rod 25 passes through the limiting block 10 and is fixed to the top surface of the laser cutter 8. The first spur gear 4 is meshed with the adjacent gear seat 2. The output end of the first motor 3 is rotatably connected to the inner wall of the slide plate 1. The threaded rod 6 is rotatably connected to the inner wall and one end of the inner surface of one side of the slide plate 1.

[0028] When the first motor 3 is started, it drives the first spur gear 4 at the adjacent position to rotate. Under the force generated by the meshing action between the first spur gear 4 and the adjacent gear seat 2, and the limiting action of the gear seat 2 on the slide plate 1, the slide plate 1 can move horizontally in the left and right directions. When the second motor 5 is started, the threaded rod 6 can rotate. Due to the abutment and limiting action of the inner wall of the slide plate 1 against the limiting block 10, the threaded seat 7 can drive the limiting block 10 and the laser cutter 8 to move horizontally in the front and back directions under the meshing action between it and the threaded rod 6, thereby realizing cutting operations in multiple directions.

[0029] Please see Figure 1-5The blocking assembly includes a movable shaft 9 rotatably connected to the inner surface of the slide plate 1 at the top of the threaded rod 6, a second spur gear 21 fixedly sleeved on one end of the outer peripheral surface of the threaded rod 6 and the movable shaft 9, a rotating shaft 11 rotatably connected to one end of the threaded seat 7, a pulley 14 sleeved on one end of the outer peripheral surface of the rotating shaft 11 and at the middle position of the outer peripheral surface of the movable shaft 9, a limiting component acting on one of the pulleys 14, abutment grooves 16 formed at both ends of the outer peripheral surface of the movable shaft 9, abutment blocks 17 inserted into the cavity of the abutment grooves 16, and a connecting belt 20 sleeved between the two pulleys 14. The inner peripheral surfaces of the pulleys 14 adjacent to the top of the abutment block 17 are fixed together, and the two second spur gears 21 are meshed together. The inner wall of one of the pulleys 14 is fixed to the outer peripheral surface of the adjacent rotating shaft 11.

[0030] When the movable shaft 9 rotates, the contact action between the contact groove 16 and the contact block 17 causes one of the pulleys 14 to rotate under the limiting action of the limiting component, thereby causing the threaded pulley 14 to drive the rotating shaft 11 to rotate under the connection action of the connecting belt 20.

[0031] Please see Figure 1-5 The limiting components include a limiting seat 15 fixed to the top of the threaded seat 7, an annular groove 18 opened at one end of the limiting seat 15, and two positioning seats 19 slidably inserted into the annular groove 18. One end of the positioning seat 19 is fixed to the surface of the adjacent pulley 14. The cross-section of the inner cavity of the annular groove 18 is T-shaped, and the cross-section of the positioning seat 19 embedded in the inner cavity surface of the annular groove 18 is T-shaped.

[0032] Because the positioning seat 19 is resisted by the inner cavity of the annular groove 18, the threaded seat 7 can drive the pulley 14 near the limiting seat 15 to move when it moves. Furthermore, the pulley 14 can rotate more smoothly due to the limiting effect of the inner wall of the annular groove 18 against the positioning seat 19.

[0033] Please see Figure 1-5 The blocking assembly also includes a rotating cylinder 12 rotatably connected to the bottom of the threaded seat 7 outside the support rod 25, and a bevel gear 13 fixedly sleeved on the outer circumferential surface of the rotating cylinder 12 and the other end of the outer circumferential surface of the rotating shaft 11. The two bevel gears 13 are meshed together. The rotating cylinder 12 is rotatably connected to the inner wall of the limiting block 10. The bottom of the rotating cylinder 12 is rotatably connected to the top surface of the laser cutter 8.

[0034] When the rotating shaft 11 rotates, it can drive one of the bevel gears 13 to rotate, thereby causing the rotating cylinder 12 to rotate under the meshing action between the two bevel gears 13. Furthermore, due to the connection relationship of the rotating cylinder 12, its movement will not affect the threaded seat 7, the limiting block 10, and the laser cutter 8.

[0035] Please see Figure 1-5 The blocking assembly also includes a sleeve 22 fixedly sleeved on the outer periphery of the rotating cylinder 12, a plurality of baffles 24 arranged at equal intervals around the bottom of the sleeve 22, and a connecting rod 23 fixed between the sleeve 22 and the baffles 24.

[0036] When the rotating cylinder 12 rotates, the sleeve 22 rotates, and under the connection of the connecting rod 23, multiple stops 24 surround the cutting position of the laser cutter 8 and make a circular motion. This reduces the amount of debris and sparks moving to the outside by the blocking effect of the stops 24, thereby reducing the probability of damage to the operator from the debris and sparks generated during cutting. Furthermore, the multiple stops 24 do not completely block the cutting position of the laser cutter 8, making it easy for the user to adjust the contact between the workpiece and the cutting position of the laser cutter 8 and to observe the cutting edge during the cutting process.
