Description

Technical Field

[0001] This utility model belongs to the technical field of laser cutting devices, and in particular relates to a laser cutting machine worktable. Background Technology

[0002] Laser cutting machines cut workpieces by focusing a high-power-density laser beam. They have advantages such as high processing accuracy, high efficiency, and low cost, and are widely used in metal processing, sheet metal manufacturing and other fields. The laser cutting machine worktable is used to support the processed parts and is the core component of the laser cutting process.

[0003] When a laser cutting machine cuts metal parts, the molten slag produced splashes and accumulates on both sides of the support components of the worktable. After cooling, it forms attached residue. Long-term accumulation of residue on the support components can affect the positioning accuracy of the workpiece, causing dimensional deviations and scratching the workpiece surface. Therefore, in the traditional way, the laser cutting machine worktable is manually cleaned or the support components are replaced after a period of use. However, manual cleaning is inefficient and replacing support components is costly. Therefore, there is a need for a laser cutting machine worktable that can improve cleaning efficiency and reduce cleaning costs. Utility Model Content

[0004] The purpose of this invention is to use a push rod motor to drive the drive component to move, causing the pulley to roll from one arc-shaped groove to another, thereby driving the slag cleaning component to move up and down. During the upward movement of the slag cleaning component, the residue attached to the side of the support beam is cleaned away, thus solving the problems of low efficiency of manual slag cleaning and high cost of slag cleaning caused by replacing the rack in the above-mentioned background technology.

[0005] The specific technical solution of this utility model is as follows:

[0006] A laser cutting machine worktable includes a table body, which is a frame structure. A frame beam is located on the upper part of the table body, and several legs are provided on the lower surface of the frame beam. Several support beams are mounted on the frame beam and are arranged in a linear array. A support platform is located below the support beams, and the support platform is fixedly connected to the legs. Several through holes are provided on the upper surface of the support platform, and a drive shaft is slidably connected to each through hole. A cleaning component is located at the top of the drive shaft, between two adjacent support beams. The two sides of the cleaning component are respectively abutted against the side surfaces of their adjacent support beams. A pulley is located at the bottom of the drive shaft. A base is located below the support platform, and a drive component is slidably connected to the upper surface of the base. A push rod motor is installed in front of the base, and the push shaft of the push rod motor is fixedly connected to the front surface of the drive component. Several arc-shaped grooves are arranged in a linear array on the upper surface of the drive component, and the arc-shaped grooves are adapted to the pulleys.

[0007] Furthermore, the frame beam includes two horizontal beams and two long beams arranged opposite each other. The horizontal beams and long beams are connected end to end to form a rectangular frame. The upper surface of the long beam is provided with a recessed platform. Several slots are arranged in a linear array on the upper surface of the recessed platform. The two ends of the support beam are respectively provided with snap-fit ​​parts. The snap-fit ​​parts are adapted to the slots. The support beam is installed on the long beam through the snap-fit ​​parts and the slots.

[0008] Furthermore, the height of the snap-fit ​​component is the same as that of the snap-fit ​​slot, the recessed platform is equipped with a pressure strip, the pressure strip has several assembly holes one, and the recessed platform has several assembly holes two that are adapted to the assembly holes one.

[0009] Furthermore, several support members are arranged in a linear array on the upper surface of the support beam, and the longitudinal section of the support members is trapezoidal.

[0010] Furthermore, the width of the slag-cleaning component is the same as the gap width between two adjacent support beams, the length of the slag-cleaning component is the same as the distance between the two long beams, and the drive shaft is located at the center of the lower surface of the slag-cleaning component.

[0011] Furthermore, a linear concave groove is provided on the upper surface of the slag cleaning component along the length direction. The linear concave groove is located at the center of the upper surface of the slag cleaning component, and the top opening width of the linear concave groove is the same as the width of the slag cleaning component.

[0012] Furthermore, guide slide rods are provided on the lower surface of the slag cleaning component, with two guide slide rods located on both sides of the drive shaft. The upper surface of the support platform is provided with through holes that are adapted to the guide slide rods. A spring is sleeved on the guide slide rod, with the upper end of the spring fixedly connected to the lower surface of the slag cleaning component and the lower end of the spring fixedly connected to the upper surface of the support platform.

[0013] Furthermore, a barrier is provided at the bottom of the guide slide rod.

[0014] Furthermore, the upper surface of the base is provided with a linear groove along the length direction, and the lower surface of the drive component is provided with a linear slider that is adapted to the linear groove. The drive component achieves a sliding connection with the base through the sliding cooperation between the linear slider and the linear groove. The base is provided with several mounting holes.

[0015] Furthermore, the bottom of the support leg is provided with a threaded hole, a threaded rod is adapted to fit inside the threaded hole, and a support foot is provided at the bottom of the threaded rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] After the laser cutting machine's worktable finishes its work, the push rod motor is activated. The push rod motor drives the drive component to move, causing the pulley to roll from an arc-shaped groove to the upper surface of the drive component. As the pulley rolls from the bottom of the arc-shaped groove to the upper surface of the drive component, it drives the cleaning component to move upward. Since the two sides of the cleaning component are in contact with the sides of the adjacent support beams, the cleaning component removes the residue attached to the sides of the support beams as it moves upward. The pulley then rolls from the upper surface of the drive component to the bottom of the adjacent arc-shaped groove, driving the cleaning component to move downward. The cleaning component then falls back down, without affecting the use of the laser cutting machine's worktable. This improves cleaning efficiency and avoids the problem of increasing cleaning costs due to replacing support beams. Attached Figure Description

Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] See Figures 1 to 6This embodiment discloses a laser cutting machine worktable, including a table body 1, which is a frame structure. A frame beam 11 is provided on the upper part of the table body 1. Several legs 12 are provided on the lower surface of the frame beam 11. Several support beams 2 are mounted on the frame beam 11 and are arranged in a linear array. A support platform 14 is provided below the support beams 2, and the support platform 14 is fixedly connected to the legs 12. In this embodiment, the support platform 14 and the legs 12 are made of metal and are connected by welding. Several through holes 141 are provided on the upper surface of the support platform 14, and a drive shaft 3 is slidably connected to each through hole 141. The top of the drive shaft 3 is provided with a clear... The slag removal component 31 can be further optimized by having one more through hole 141 than the number of support beams 2. This ensures that slag removal components 31 are present on both sides of each support beam 2, improving the slag removal effect. The slag removal components 31 are located between two adjacent support beams 2. In this embodiment, the slag removal components 31 at the front and rear ends of the laser cutting machine worktable are located between the support beams 2 and the frame beams 11, respectively. The two sides of the slag removal components 31 are respectively attached to the side surfaces of their adjacent support beams 2, improving the slag removal effect. A pulley 32 is provided at the bottom of the transmission shaft 3, and a base 4 is provided below the support platform 14. The upper surface of the base 4 is slidably connected to... A push rod motor 6 is mounted in front of the drive component 5 and the base 4. The push shaft of the push rod motor 6 is fixedly connected to the front surface of the drive component 5. In this embodiment, the push shaft of the push rod motor 6 and the drive component 5 are made of metal and are connected by welding. Several arc-shaped grooves 51 are linearly arrayed on the upper surface of the drive component 5. The arc-shaped grooves 51 are adapted to the pulleys 32. The several arc-shaped grooves 51 form a wave-shaped structure. The pulleys 32 can roll from the bottom of one arc-shaped groove 51 to the bottom of another arc-shaped groove 51. When the laser cutting machine worktable finishes its work, the push rod motor 6 is started, which pushes the drive component 5 to move. The pulley 32 rolls from the bottom of an arc-shaped groove 51 to the upper surface of the drive component 5. As the pulley 32 rolls from the bottom of the arc-shaped groove 51 to the upper surface of the drive component 5, it drives the cleaning component 31 to move from bottom to top. Since the two sides of the cleaning component 31 are in contact with the side surfaces of the adjacent support beam 2, the cleaning component 31 cleans the residue attached to the side of the support beam 2 during its upward movement. As the pulley 32 rolls from the upper surface of the drive component 5 to the bottom of the adjacent arc-shaped groove 51, it drives the cleaning component 31 to move from top to bottom. The cleaning component 31 falls back down without affecting the use of the laser cutting machine's worktable.

[0035] The frame beam 11 includes two horizontal beams 111 and two long beams 112 arranged opposite to each other. The horizontal beams 111 and the long beams 112 are connected end to end to form a rectangular frame. In this embodiment, the two horizontal beams 111 and the two long beams 112 are made of metal and are connected by welding. The upper surface of the long beam 112 is provided with a recess 13. Several slots 131 are linearly arranged on the upper surface of the recess 13. The two ends of the support beam 2 are respectively provided with snap-fit ​​pieces 21. The snap-fit ​​pieces 21 are adapted to the slots 131. The support beam 2 is installed on the long beam 112 by snap-fitting the snap-fit ​​pieces 21 with the slots 131.

[0036] The height of the snap-fit ​​part 21 is the same as that of the slot 131. The recessed platform 13 is equipped with a pressure strip 7. The pressure strip 7 has several first mounting holes 71. The recessed platform 13 has several second mounting holes 132 that are adapted to the first mounting holes 71. The pressure strip 7 is fixedly installed on the recessed platform 13 through the first mounting holes 71, the second mounting holes 132 and the bolt assembly. The pressure strip 7 further fixes the support beam 2 to the platform 1, increases the stability of the support beam 2 and prevents the support beam 2 from moving up and down during the slag cleaning process, which would affect the slag cleaning effect.

[0037] Several support members 22 are arranged in a linear array on the upper surface of the support beam 2. The longitudinal section of the support member 22 is trapezoidal, so the top of the support member 22 is flat to prevent the top corner of the support member 22 from scratching the workpiece. The several linearly arrayed support members 22 form a tooth-like structure, which reduces the contact area between the support beam 2 and the workpiece and reduces the damage to the support beam 2 by the laser when the laser cuts through the workpiece.

[0038] The width of the slag-cleaning component 31 is the same as the gap width between two adjacent support beams 2, and the length of the slag-cleaning component 31 is the same as the vertical distance between the two long beams 112. In this embodiment, the distance between the support beams 2 near the front and rear ends of the laser cutting machine worktable and the frame beams 11 is equal to the gap width between two adjacent support beams 2, which improves the slag-cleaning effect of the slag-cleaning component 31. The transmission shaft 3 is located at the center of the lower surface of the slag-cleaning component 31, ensuring that the lifting force applied by the transmission shaft 3 to the slag-cleaning component 31 can be evenly diffused.

[0039] The upper surface of the slag-cleaning component 31 is provided with a linear concave groove 311 along the length direction. The linear concave groove 311 is located at the center of the upper surface of the slag-cleaning component 31. The width of the top opening of the linear concave groove 311 is the same as the width of the slag-cleaning component 31, so that the top of the two side walls of the slag-cleaning component 31 forms a shovel-shaped edge, which makes it easier to clean the residue. The residue falls into the linear concave groove 311, which facilitates the collection and cleaning of the fallen residue.

[0040] The lower surface of the slag-cleaning component 31 is provided with guide slide rods 33. The two guide slide rods 33 are located on both sides of the transmission shaft 3. In this embodiment, the slag-cleaning component 31, the transmission shaft 3, and the guide slide rods 33 are made of metal and are connected by welding. The upper surface of the support platform 14 is provided with a through hole 142 that is adapted to the guide slide rod 33. A spring 34 is sleeved on the guide slide rod 33. The upper end of the spring 34 is fixedly connected to the lower surface of the slag-cleaning component 31, and the lower end of the spring 34 is fixedly connected to the upper surface of the support platform 14. The guide slide rod 33 makes the stroke trajectory of the slag-cleaning component 31 more stable. The spring 34 is a tension spring. When the slag-cleaning component 31 rises, the spring 34 deforms and pulls the slag-cleaning component 31 back quickly to prevent the slag-cleaning component 31 from falling back incompletely and affecting the subsequent use of the laser cutting machine worktable.

[0041] A barrier 331 is provided at the bottom of the guide slide rod 33. The outer diameter of the barrier 331 is larger than the inner diameter of the through hole 142 to prevent the guide slide rod 33 from falling out of the through hole 142.

[0042] The upper surface of the base 4 is provided with a linear groove 41 along the length direction, and the lower surface of the drive component 5 is provided with a linear slider 52 adapted to the linear groove 41. The drive component 5 achieves a sliding connection with the base 4 through the sliding cooperation between the linear slider 52 and the linear groove 41, making the sliding trajectory of the drive component 5 more stable. It can be further optimized that the linear groove 41 is an inverted T-shaped groove to prevent the linear slider 52 from falling out of the linear groove 41. The base 4 is provided with several mounting holes 42. The base 4 is fixed to the ground through the cooperation of the mounting holes 42 and the expansion bolts, increasing the stability of the base 4.

[0043] The bottom of the support leg 12 is provided with a threaded hole, and a threaded rod is adapted to fit inside the threaded hole. The bottom of the threaded rod is provided with a foot 121. By screwing the foot 121, the overall height of the platform 1 can be adjusted.

[0044] Working principle: After the laser cutting machine's worktable finishes operation, the push rod motor 6 is activated, which drives the drive component 5 to move. This causes the pulley 32 to roll from the bottom of an arc-shaped groove 51 to the upper surface of the drive component 5. As the pulley 32 rolls from the bottom of the arc-shaped groove 51 to the upper surface of the drive component 5, it drives the cleaning component 31 to move upward. Since the two sides of the cleaning component 31 are in contact with the side surfaces of its adjacent support beam 2, the cleaning component 31 cleans the residue attached to the side of the support beam 2 during its upward movement. The cleaning component 31 falls into the linear concave groove 311 for easy collection and cleaning. As the pulley 32 rolls from the upper surface of the drive component 5 to the bottom of the adjacent arc-shaped groove 51, it drives the cleaning component 31 to move downward. The cleaning component 31 falls back down without affecting the use of the laser cutting machine's worktable, thus improving the cleaning efficiency and avoiding the problem of increasing cleaning costs due to replacing the support beam 2.
