Description

Technical Field

[0001] The utility model relates to the technical field of slide table mechanisms, and particularly relates to a gear-rack slide table mechanism. Background Technique

[0002] A gear-rack slide table mechanism is a mechanical transmission device that converts rotational motion into linear motion, and it mainly consists of a gear and a rack.

[0003] During the use of the existing gear-rack slide table mechanism, although it can drive the slide table to move, the slide table will get stuck when moving, resulting in inaccurate positioning during use. At the same time, it cannot damp the vibration of the device, causing the device to collide with the outer shell of the device when moving, and the slider will get stuck when the device collides. Therefore, a gear-rack slide table mechanism is introduced. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a gear-rack slide table mechanism, which has the advantages of movement and vibration damping, and solves the problems raised in the above background technique.

[0005] The utility model provides the following technical solution: A gear-rack slide table mechanism includes a housing, the inner wall of the housing is fixedly assembled with a limiting rod, a damping component is arranged on the inner wall of the housing, a chute and a limiting groove are respectively opened at the top of the limiting rod, a slider body is slidably connected to the inner wall of the chute, a limiting block is slidably connected to the inner wall of the limiting groove, and a slide table body is fixedly assembled at the top of the slider body.

[0006] As a preferred technical solution of the utility model: A motor is fixedly assembled at the top of the slide table body, a first gear is fixedly assembled on the power output shaft of the motor, a second gear is rotatably connected to the bottom of the slide table body, and a rack body is fixedly assembled at the top of the limiting rod.

[0007] As a preferred technical solution of the utility model: The damping component includes a fixed block, a rotating rod is rotatably connected to the inner wall of the fixed block, one end of a compression rod is fixedly assembled on the outer wall of the rotating rod, a rotating column is rotatably connected to the inner wall of the other end of the compression rod, one end of a rotating block is fixedly assembled on the outer wall of the rotating column, a protection plate is fixedly assembled at the other end of the rotating block, and a spring is fixedly assembled on the outer wall of the protection plate.

[0008] As a preferred technical solution of the utility model: Both the fixed block and the spring are fixedly assembled with the inner wall of the housing, and the protection plate is slidably connected to the inner wall of the housing.

[0009] As a preferred technical solution of the present utility model: The limit block is fixedly assembled with the bottom of the sliding table body, the first gear is in meshing transmission with the second gear, and the second gear is in meshing transmission with the rack body.

[0010] As a preferred technical solution of the present utility model: The number of the limit rods, the slider body and the limit blocks is two, and the two limit rods, the slider body and the limit blocks are respectively located at the top of the limit rod.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. For this gear-rack sliding table mechanism, the slider body is limited by the chute, so that the slider body slides more stably on the inner wall of the chute without jamming. The sliding table body is limited by the limit groove and the limit block, avoiding the situation that the device shifts and falls off due to external factors during use, thereby reducing the service life of the device, and ensuring that the sliding table body does not jam during movement, making the device more stable.

[0013] 2. For this gear-rack sliding table mechanism, when the sliding table body collides with the protection plate, the protection plate is pressed to exert pressure on the rotating block after being stressed. The rotating block drives the rotating column to rotate inside the pressure-receiving rod, so that the rotating block exerts pressure on the pressure-receiving rod when rotating. After the pressure-receiving rod is stressed, it drives the rotating rod to rotate inside the fixed block. When the protection plate moves, it presses the spring, releasing the elastic potential energy of the spring. The spring releases pressure on the protection plate, and the resilience and pressure of the protection plate are divided and offset from each other, thereby realizing vibration reduction of the device.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figure 1 - Figure 6 , a gear-rack slide mechanism, including an outer shell 1, a limit rod 2 is fixedly assembled on the inner wall of the outer shell 1, a vibration damping component 3 is arranged on the inner wall of the outer shell 1, a slide groove 6 and a limit groove 7 are respectively opened at the top of the limit rod 2, a slide block body 11 is slidably connected to the inner wall of the slide groove 6, a limit block 12 is slidably connected to the inner wall of the limit groove 7, and a slide table body 4 is fixedly assembled on the top of the slide block body 11.

[0024] In the above structure, through the slide groove 6, the slide block body 11 can slide smoothly on the inner wall of the slide groove 6, ensuring enhanced stability of the slide block body 11 during the sliding process and avoiding the occurrence of jamming phenomena. At the same time, the slide table body 4 is effectively limited by the limit groove 7 and the limit block 12, preventing the equipment from shifting or falling off during use due to external factors, thereby reducing the wear of the equipment, extending the service life, and ensuring the smooth movement of the slide table body 4, further enhancing the overall stability of the equipment.

[0025] In a preferred implementation mode: a motor 5 is fixedly assembled on the top of the slide table body 4, a first gear 9 is fixedly assembled on the power output shaft of the motor 5, a second gear 10 is rotatably connected to the bottom of the slide table body 4, and a rack body 8 is fixedly assembled on the top of the limit rod 2.

[0026] In the above structure, the first gear 9 is driven to rotate by the power output shaft of the motor 5, and the first gear 9 is in meshing transmission with the second gear 10, so that when the first gear 9 rotates, it will drive the second gear 10 to rotate. Then, through the meshing transmission between the second gear 10 and the rack body 8, when the second gear 10 rotates, it will drive the slide table body 4 to move, thereby achieving the effect of movement.

[0027] In a preferred embodiment: The damping component 3 includes a fixed block 301. The inner wall of the fixed block 301 is rotatably connected to a rotating rod 302. One end of a compression rod 303 is fixedly assembled on the outer wall of the rotating rod 302. The inner wall of the other end of the compression rod 303 is rotatably connected to a rotating column 304. One end of a rotating block 305 is fixedly assembled on the outer wall of the rotating column 304. The other end of the rotating block 305 is fixedly assembled with a protection plate 306. A spring 307 is fixedly assembled on the outer wall of the protection plate 306.

[0028] In the above structure, after the sliding table body 4 collides with the protection plate 306, the sliding table body 4 applies pressure to the protection plate 306, thereby causing the rotating block 305 to be pressured. Subsequently, the rotating block 305 pushes the rotating column 304 to rotate along the inner wall of the compression rod 303. At the same time, during the rotation process, pressure is applied to the compression rod 303. After the compression rod 303 is pressured, it causes the rotating rod 302 to rotate on the inner wall of the fixed block 301. In addition, during the movement of the protection plate 306, pressure is applied to the spring 307, resulting in the release of the elastic potential energy of the spring 307. After the spring 307 releases the pressure, it interacts with the resilience of the protection plate 306, achieving the damping effect by mutual cancellation.

[0029] In a preferred embodiment: Both the fixed block 301 and the spring 307 are fixedly assembled with the inner wall of the housing 1, and the protection plate 306 is slidably connected to the inner wall of the housing 1.

[0030] In the above structure, the housing 1 is used to limit the damping component 3, so that the damping component 3 will not fall off during use. The rotating block 305 is used to limit the protection plate 306, so that the protection plate 306 can move on the inner wall of the housing 1 after being pressured.

[0031] In a preferred embodiment: The limit block 12 is fixedly assembled with the bottom of the sliding table body 4. The first gear 9 meshes with the second gear 10 for transmission, and the second gear 10 meshes with the rack body 8 for transmission.

[0032] In the above structure, the sliding table body 4 is used to limit the limit block 12, so that the sliding table body 4 will drive the limit block 12 to move when it moves. When the first gear 9 rotates, it will drive the second gear 10 to rotate. At the same time, when the second gear 10 rotates, it will drive [the relevant part] to move.

[0033] In a preferred embodiment: The number of the limit rods 2, the slider body 11, and the limit blocks 12 are all two, and the two limit rods 2, the slider body 11, and the limit blocks 12 are respectively located at the top of the limit rod 2.

[0034] In the above structure, through the two limiting rods 2, the slider body 11 and the limiting block 12, the sliding table body 4 is made more stable during sliding and will not fall off.

[0035] Working principle: The power output shaft of the motor 5 drives the first gear 9 to rotate. The first gear 9 is meshed with the second gear 10 for transmission, so that the first gear 9 drives the second gear 10 to rotate synchronously during rotation. Subsequently, the second gear 10 is meshed with the rack body 8 for transmission to ensure that the second gear 10 can push the sliding table body 4 to displace during rotation, so as to achieve the expected moving effect. The slider body 11 is positioned through the chute 6 to ensure that the slider body 11 slides stably on the inner wall of the chute 6 and avoid jamming. At the same time, the sliding table body 4 is positioned by using the limiting groove 7 and the limiting block 12 to prevent the equipment from shifting or falling off due to external factors during use, thereby reducing the risk of reducing the service life of the equipment and ensuring that the sliding table body 4 will not jam during movement, improving the stability of the equipment. When the sliding table body 4 collides with the protection plate 306, the protection plate 306 is subjected to pressure and transmits it to the rotating block 305. The rotating block 305 drives the rotating column 304 to rotate inside the pressure receiving rod 303 and applies pressure to the pressure receiving rod 303 at the same time. After being pressed, the pressure receiving rod 303 pushes the rotating rod 302 to rotate inside the fixed block 301. During the movement of the protection plate 306, the spring 307 is pressed, prompting the elastic potential energy of the spring 307 to be released. Finally, the spring 307 releases pressure on the protection plate 306, so that the resilience of the protection plate 306 cancels out the applied pressure, thereby realizing the vibration damping effect of the equipment.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
