Description

Technical Field

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

[0002] Laser cutting machines use a focused high-power-density laser beam to irradiate the surface of the workpiece, causing the material to melt or vaporize instantly, thus completing the cutting operation. The worktable of the laser cutting machine uses a rack and pinion to support the workpiece.

[0003] Because slag generated during laser cutting adheres to the toothed rack, the accumulation of slag on the top of the rack not only scratches the workpiece but also creates a height difference between the tooth tips, causing the workpiece to tilt due to uneven force when placed. During the cutting process, the workpiece vibrates under the impact of the laser, resulting in deviations from the design path and reduced processing accuracy. Therefore, after a period of use, the toothed rack needs to be cleaned by workers. If a tooth breaks during the cleaning process or the slag is difficult to remove, the rack must be scrapped and replaced with a new one, increasing the company's production costs. Therefore, there is a need for a laser cutting machine worktable toothed rack that can extend its service life and reduce equipment replacement costs. Utility Model Content

[0004] The purpose of this invention is to improve the service life of the rack body by providing teeth on the upper and lower surfaces of the rack body. When one tooth is worn out, the rack body can be flipped over to use the other tooth, thereby solving the problem in the background art where the rack has to be scrapped and replaced with a new rack when the tooth breaks during the slag removal process or the slag is difficult to remove, which increases the production cost of the enterprise.

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

[0006] A rack for a laser cutting machine worktable includes a rack body with a rectangular cross-section. Several teeth are linearly arrayed on the upper and lower surfaces of the rack body. Linear grooves are respectively provided on the front and rear surfaces of the rack body, and several clamping mechanisms are slidably connected to the linear grooves.

[0007] Furthermore, several teeth on the upper surface of the rack body and several teeth on the lower surface of the rack body are arranged opposite each other.

[0008] Furthermore, the longitudinal section of the tooth is trapezoidal.

[0009] Furthermore, the upper surface of the tooth is a convex arc surface.

[0010] Furthermore, the clamping mechanism includes a slider that is used with the linear slide. A clamping member is provided on one side of the slider. The clamping member has a rectangular cross-section. A slot is provided vertically on the front surface of the clamping member. A push rod is threadedly connected to one side surface of the clamping member. One end of the push rod is located outside the slot, and the other end of the push rod is located inside the slot.

[0011] Furthermore, a limiting groove is provided vertically on one side of the clamping component, and a limiting component is slidably connected in the limiting groove. The limiting component is provided with a threaded through hole, and the push rod is a cylinder with an external thread on its circumference that matches the threaded through hole.

[0012] Furthermore, the front and rear facades of the limiting slide are vertically opposite to each other with positioning slides, and the two sides of the limiting component are opposite to each other with positioning components that are used in conjunction with the positioning slides.

[0013] Furthermore, a screwing component is provided at one end of the push rod outside the slot. The screwing component has a rectangular cross-section, and its long side is perpendicular to the central axis of the push rod.

[0014] Furthermore, a buffer component is connected to one end of the push rod located in the slot. The buffer component is a frustum, and the top surface of the frustum is connected to the push rod. The buffer component is made of rubber.

[0015] Furthermore, the grooves at both ends of the linear slide are located on the two sides of the rack body, and the linear slide is a T-shaped groove.

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

[0017] 1. When the slag on the teeth cannot be removed or the teeth are damaged, simply remove the rack body from the laser cutting machine worktable, flip the rack body so that the scrapped teeth face down and the good teeth face up, and then install the rack body on the laser cutting machine worktable for continued use. This extends the service life of the rack body, reduces the cost of replacing worn equipment for the manufacturing company, and improves production efficiency.

[0018] 2. When the rack body needs to be installed on the laser cutting machine worktable, simply slide the clamping mechanism to the installation position on the worktable via the linear slide, then insert the slot into the rack mounting plate on the laser cutting machine worktable, and screw on the top rod. The rack mounting plate will be clamped by the top rod and the slot on one side, thus completing the installation of the rack body. The sliding connection between the clamping mechanism and the rack body allows multiple clamping mechanisms to hold rack mounting plates at different locations, improving the adaptability of the rack body. Furthermore, since the slots at both ends of the linear slide are located on the two sides of the rack body, it is convenient for the clamping mechanism to slide out of the linear slide and flip back into the linear slide when the rack body needs to be replaced. This, combined with the reuse of the rack body, improves the practicality of the clamping mechanism. Attached Figure Description

[0028] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. 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.

[0030] See Figures 1 to 4This embodiment discloses a rack for a laser cutting machine worktable, including a rack body 1 with a rectangular cross-section. Several teeth 11 are linearly arrayed on the upper and lower surfaces of the rack body 1. Linear grooves 12 are respectively provided on the front and rear surfaces of the rack body 1, and several clamping mechanisms 2 are slidably connected to the linear grooves 12. When slag on the teeth 11 cannot be removed or the teeth 11 are damaged, the rack body 1 can be removed from the laser cutting machine worktable and flipped so that the damaged teeth 11 face down, with the other side... With the teeth 11 facing upwards, the rack body 1 is then installed on the laser cutting machine worktable for continued use, thus extending the service life of the rack body 1. When the rack body 1 needs to be installed on the laser cutting machine worktable, simply slide the clamping mechanism 2 through the linear slide 12 to the position of the rack mounting plate on the laser cutting machine worktable, and then use the clamping mechanism 2 to clamp the rack mounting plate, thereby completing the installation of the rack body 1. The sliding connection between the clamping mechanism 2 and the rack body 1 allows several clamping mechanisms 2 to clamp rack mounting plates at different locations.

[0031] Several teeth 11 on the upper surface of the rack body 1 and several teeth 11 on the lower surface of the rack body 1 are arranged opposite to each other. When the teeth 11 on the upper surface of the rack body 1 or the teeth 11 on the lower surface of the rack body 1 are subjected to force, the load can be evenly distributed through the rack body 1, thereby extending the service life of the rack body 1.

[0032] The longitudinal section of tooth 11 is trapezoidal, so that the upper surface of tooth 11 forms a plane, preventing sharp corners from scratching the workpiece.

[0033] The upper surface of the tooth 11 is a convex arc surface, which further prevents the upper surface of the tooth 11 from scratching the workpiece. In addition, the convex arc surface can reduce the friction between the workpiece and the top surface of the tooth 11, making it easier for the workpiece to move on the rack body 1.

[0034] See Figure 2 The clamping mechanism 2 includes a slider 21 that works with the linear slide 12. A clamping member 22 is provided on one side of the slider 21. The clamping member 22 has a rectangular cross-section and a slot 221 is provided vertically on the front surface of the clamping member 22. A push rod 3 is threadedly connected to one side surface of the clamping member 22. One end of the push rod 3 is located outside the slot 221, and the other end of the push rod 3 is located inside the slot 221. When the rack body 1 needs to be installed on the laser cutting machine worktable, the clamping mechanism 2 is simply slid through the linear slide 12 to the position of the rack mounting plate on the laser cutting machine worktable. Then, the slot 221 is inserted into the rack mounting plate on the laser cutting machine worktable, and the push rod 3 is screwed on. The rack mounting plate is clamped by the cooperation between the end of the push rod 3 located in the slot 221 and the inner surface of one side of the slot 221, thereby completing the installation of the rack body 1. The sliding connection between the clamping mechanism 2 and the rack body 1 allows multiple clamping mechanisms 2 to clamp rack mounting plates at different locations.

[0035] The clamping member 22 has a vertical limiting groove 222 on one side of its facade. A limiting member 4 is slidably connected in the limiting groove 222. The limiting member 4 has a threaded through hole 41. The push rod 3 is a cylinder. The circumferential surface of the push rod 3 has an external thread that matches the threaded through hole 41. Through the sliding connection between the limiting member 4 and the limiting groove 222, the working height of the push rod 3 can be adjusted, further improving the adaptability of the clamping mechanism 2.

[0036] The front and rear facades of the limiting slide 222 are vertically opposite to each other with positioning slide 223. The limiting member 4 is provided with positioning members 42 on both sides that are used in conjunction with the positioning slide 223. The limiting member 4 achieves sliding connection with the clamping member 22 through the cooperation of the positioning members 42 and the positioning slide 223.

[0037] The top rod 3 is provided with a screwing part 31 at one end outside the slot 221. The screwing part 31 has a rectangular cross-section and its long side is perpendicular to the central axis of the top rod 3. The screwing part 31 is provided to facilitate the screwing operation of the top rod 3.

[0038] One end of the push rod 3 located in the slot 221 is connected to a buffer 32. The buffer 32 is a frustum, and the top surface of the frustum is connected to the push rod 3. The buffer 32 is made of rubber. The rubber material has a buffering effect and can also increase the friction between the push rod 3 and the rack mounting plate, making the rack body 1 clamped more stably.

[0039] The slots at both ends of the linear slide 12 are located on the two sides of the rack body 1. Since the slots at both ends of the linear slide 12 are located on the two sides of the rack body 1, it is convenient that when the rack body 1 needs to be replaced, the clamping mechanism 2 can slide out from the linear slide 12 and flip back into the linear slide 12. This improves the practicality of the clamping mechanism 2 in conjunction with the reuse of the rack body 1. The linear slide 12 is a T-shaped groove. The T-shaped design can prevent the slider 21 from falling out of the linear slide 12 and increase the stability of the sliding connection between the clamping mechanism 2 and the rack body 1.

[0040] Working principle: When the slag on the tooth 11 cannot be removed or the tooth 11 is damaged, simply remove the rack body 1 from the laser cutting machine worktable, flip the rack body 1 so that the damaged tooth 11 faces down and the good tooth 11 faces up, and then install the rack body 1 on the laser cutting machine worktable for continued use. This extends the service life of the rack body 1, reduces the cost of replacing worn equipment for the manufacturing company, and improves production efficiency. When the rack body 1 needs to be installed on the laser cutting machine worktable, simply slide the clamping mechanism 2 through the linear slide 12 to the position of the rack mounting plate on the laser cutting machine worktable, and then clamp the slot 2. 21 is inserted into the rack mounting plate on the laser cutting machine worktable. The top rod 3 is screwed on, and the rack mounting plate is clamped by the top rod 3 and the inner side of the slot 221, thus completing the installation of the rack body 1. The sliding connection between the clamping mechanism 2 and the rack body 1 allows several clamping mechanisms 2 to clamp rack mounting plates at different locations, improving the adaptability of the rack body 1. Furthermore, since the slots at both ends of the linear slide 12 are located on the two sides of the rack body 1, it is convenient that when the rack body 1 needs to be replaced, the clamping mechanism 2 can slide out of the linear slide 12 and flip and reinstall into the linear slide 12, which, together with the reuse of the rack body 1, improves the practicality of the clamping mechanism 2.
