Description

Technical Field

[0001] The utility model relates to the technical field of slide seats, in particular to a high-precision guide mechanism for a metal slide seat. Background Art

[0002] A slide is a device used to support and guide moving parts in mechanical equipment. It is usually made of high-strength metal materials such as cast iron and alloy steel to ensure that it has sufficient rigidity and load-bearing capacity to withstand various forces during movement, including the gravity from the load, the inertia force during movement, and other possible external forces. Slides are usually used in conjunction with guide rails to enable moving parts to move smoothly in a specific direction.

[0003] The metal slide guide mechanism is a mechanical structure consisting primarily of a metal slide and guide rail. The precise guiding motion of the slide relative to the guide rail is achieved through the rolling of balls or rollers between the guide rail and the slide. When the slide is subjected to an external force, the balls or rollers roll between the guide rail and the slide, converting sliding friction into rolling friction. This significantly reduces frictional resistance, improves guiding accuracy and motion smoothness, and enables related components to perform precise and smooth linear or curved motion in the predetermined direction.

[0004] However, traditional equipment usually uses screws and nuts to connect and fix the slide and guide rail, and the installation process is relatively cumbersome. During the operation of the equipment, especially under vibration, impact or repeated loads, it is easy to loosen. When the connection between the slide and the guide rail becomes loose, the relative position between the two will change, thereby affecting the guiding accuracy of the entire mechanism. Therefore, a high-precision metal slide guide mechanism is proposed to solve the above problems. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The sliding assembly includes a plurality of second slide rail plates, the second slide rail plates are arranged on the inner wall of the slide body, and the connecting strip is slidably connected to the inside of the bottom plate;

[0010] As a further description of the above technical solution:

[0011] A plurality of balls are rotatably connected on both sides of the interior of the slide body, and the balls are rotatably connected to one side of the second slide rail plate, and the second slide rail plate is fixedly connected to both sides of the rubber plate;

[0012] As a further description of the above technical solution:

[0013] One side of each of the two slide rail plates is fixedly connected to a plurality of connection blocks 1, and each of the connection blocks 1 is rotatably connected to a rotating shaft 1;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the rotating shaft 1 is fixedly connected to a rotating plate, and the interior of the rotating plate is fixedly connected to the rotating shaft 2;

[0016] As a further description of the above technical solution:

[0017] The outer walls of the two rotating shafts are both rotatably connected to the connecting blocks 2, and the connecting blocks 2 on both sides are fixedly connected to the moving blocks;

[0018] As a further description of the above technical solution:

[0019] The movable block is internally slidably connected to a limiting post, and the limiting post is fixedly connected between the rubber plates on both sides;

[0020] As a further description of the above technical solution:

[0021] A second spring is fixedly connected between the moving blocks on both sides, and the second spring is arranged on the outer wall of the limiting column.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, by pressing the pressing plate, the slot connector is moved to the outer wall of the card ball, and then the pressing plate is released, and the movable card block is used to push the card ball to fix the slot connector, thereby realizing rapid installation and disassembly between the base plate and the slide body, solving the problem that the traditional equipment installation process is relatively cumbersome and prone to loosening under vibration, impact or repeated loads, simplifying the equipment installation process, improving the stability of the equipment, and enhancing the guiding accuracy of the equipment.

[0024] 2. In the utility model, the ball bearing pushes the slide plate 2 to move, thereby driving the rubber plate to compress and the spring 2 to stretch. The rebound characteristics of the spring 2 are used to push the arc surface on one side of the slide plate 2 that fits the outer wall of the ball bearing to fit tightly with the ball bearing. This solves the problem that during the movement of traditional equipment, there is a certain gap between the ball bearing and the guide rail, which causes a certain amount of shaking and leads to movement deviation. With the cooperation of the structure, the tightness of the connection between the slide plate 2 and the ball bearing is enhanced, and the guiding accuracy of the equipment is improved.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a high-precision guide mechanism for a metal slide, including a base plate 1, a plurality of pressing plates 2 are arranged on the top of the base plate 1, a plurality of connecting strips 3 are fixedly connected to the bottom of the pressing plates 2, a connecting ring 8 is fixedly connected to the bottom of the connecting strips 3, a moving card block 13 is fixedly connected to the bottom of the connecting ring 8, a plurality of springs 12 are fixedly connected to the inside of the moving card block 13, and the rebound force of the spring 12 is used to provide power support for the movement of the moving card block 13, the bottom of the spring 12 is fixedly connected to a fixed block 2 11, the fixed block 2 11 is fixedly connected to the inside of the base plate 1, a plurality of card balls 10 are fixedly connected to the top of the card ball 10, and a fixed block 9 is arranged on the top of the card ball 10, and the acute angles on both sides of the fixed block 9 are used to block the card ball 10 to prevent it from rolling to On the outside, the fixed block 9 is fixedly connected to the inside of the base plate 1, and the outer wall of the card ball 10 is provided with a card slot connector 14. The card slot of the outer wall of the card slot connector 14 fits with the outer wall of the card ball 10 to ensure that the card ball 10 can be stuck in the outer wall of the card slot connector 14. The bottom of the card slot connector 14 is fixedly connected to the slide body 4. A plurality of rubber plates 7 are provided at the bottom of the base plate 1. Both sides of the rubber plate 7 are fixedly connected to the slide plate 15. The slide plate 15 is slidably connected to the inner wall of the slide body 4. A sliding component is provided on one side of the slide plate 15. The sliding component is used to enhance the sliding accuracy of the slide body 4. The sliding component includes a plurality of slide plates 26. The slide plate 26 is provided on the inner wall of the slide body 4. The connecting bar 3 is slidably connected to the inside of the base plate 1. A plurality of balls 16 are rotatably connected on both sides of the inside of the slide body 4.

[0033] Specifically, during the installation process of the slide body 4 and the base plate 1, it is first necessary to press the pressing plate 2 downward, and drive the moving block 13 at the bottom of the connecting ring 8 to move downward synchronously through the connecting strip 3. During the movement, the spring 12 inside the moving block 13 will be compressed. At the same time, the vertical plane of the inner wall of the moving block 13 will move away from the outer wall of the card ball 10. At this time, the slot connector 14 on one side of the slide body 4 is moved to the inner wall surface of the fixed block 2 11 and the fixed block 1 9. When one side of the slot connector 14 moves to the top of the inner wall of the fixed block 1 9, the slot on the outer wall of the slot connector 14 will be at the same height as the card ball 10. Then release the downward pressure on the pressing plate 2, and the spring 12 will start to rebound, thereby driving the moving block 13 to move upward. In this process, the vertical plane of the inner wall of the moving block 13 The surface will push the card ball 10 to move into the card slot of the outer wall of the card slot connector 14, and the card ball 10 will lock and fix the card slot connector 14, and at the same time, the vertical plane of the inner wall of the mobile card block 13 will squeeze and block the card ball 10, ensuring that the card ball 10 always remains in the card slot of the outer wall of the card slot connector 14, thereby achieving a stable installation connection between the slide body 4 and the base plate 1. When disassembly is required, the pressing plate 2 is pressed again to move the vertical plane of the inner wall of the mobile card block 13 out of the outer wall of the card ball 10, thereby moving the card slot connector 14 out of the inside of the base plate 1, realizing the disassembly of the slide body 4, improving the installation and disassembly efficiency of the slide body 4, and enhancing the stability of the connection, avoiding shaking between the base plate 1 and the slide body 4 due to vibration, impact or repeated loads, thereby maintaining the movement accuracy of the base plate 1.

[0034] Reference Figure 1 and Figure 4 , the ball 16 is rotatably connected to one side of the slide plate 2 6, and the arc surface on one side of the slide plate 2 6 fits with the arc surface of the outer wall of the ball 16. The slide plate 2 6 is fixedly connected to both sides of the rubber plate 7. The extrudable characteristics of the rubber plate 7 are used to provide a moving space for the slide plate 2 6. One side of the slide plate 2 6 is fixedly connected with multiple connecting blocks 17. The interior of the connecting block 17 is rotatably connected with a rotating shaft 15. The outer wall of the rotating shaft 15 is fixedly connected with a rotating plate 18. The rotating shaft 15 is used to convert the linear motion of the connecting block 17 into the rotational motion of the rotating plate 18. The interior of the rotating plate 18 is fixedly connected with a rotating shaft 23. The rotating shaft 2 The outer walls of 23 are rotatably connected with connecting blocks 2 19, and the rotating shaft 23 is used to convert the rotational motion of the rotating plate 18 into the linear motion of the connecting blocks 2 19. A moving block 20 is fixedly connected between the connecting blocks 19 on both sides. The internal sliding connection of the moving block 20 is connected to a limiting column 21, and the limiting column 21 is used to guide and limit the movement of the moving block 20. The limiting column 21 is fixedly connected between the rubber plates 7 on both sides. A spring 22 is fixedly connected between the moving blocks 20 on both sides, and the rebound characteristics of the spring 22 are used to rebound the moving force of the moving block 20. The spring 22 is set on the outer wall of the limiting column 21.

[0035] Specifically, when the slide body 4 moves to the outer wall of the track, the balls 16 inside the slide body 4 will exert an extrusion force on the slide rail plates 2 6 on both sides. With this extrusion, the slide rail plates 2 6 will be forced to compress inward, and at the same time, the rubber plate 7 will be compressed synchronously. At the same time, the connecting block 17 will move along with the movement of the slide rail plate 2 6. The movement of the connecting block 17 is transmitted to the rotating plate 18 through the rotating shaft 15, driving the rotating plate 18 to rotate. The rotation of the rotating plate 18 drives the connecting block 2 19 to move accordingly through the rotating shaft 23. The connecting block 2 19 will slide along the outer wall of the limit column 21 during the movement. The limit column The existence of 21 limits and guides the movement of the connecting block 2 19, ensuring that it moves within the predetermined trajectory. The movement of the connecting block 2 19 also causes the spring 2 22 to be stretched. According to the elastic characteristics of the spring 22, when the spring 22 is stretched, it will generate a restoring force, which will be transmitted to the outer wall of the slide plate 2 6. When the slide plate 2 6 is subjected to this restoring force, it will exert an extrusion force on the ball 16, thereby reducing the connection gap between the slide plate 2 6 and the ball 16, improving the tightness of the connection, ensuring that when the slide body 4 stops moving, displacement due to inertia is avoided, and improving the accuracy of equipment guidance.

[0036] Working principle: During the installation process of the slide body 4 and the base plate 1, the pressing plate 2 is pressed downward, thereby driving the moving block 13 at the bottom of the connecting ring 8 to move downward synchronously through the connecting strip 3. When the moving block 13 moves, the spring 12 inside it will be compressed. When the moving block 13 moves, it will drive the vertical plane of the inner wall to move out from the outer wall of the card ball 10. At this time, the slot connector 14 on one side of the slide body 4 is moved to the inner wall of the fixed block 2 11 and the fixed block 1 9. When one side of the slot connector 14 moves to the top of the inner wall of the fixed block 1 9, the slot on the outer wall of the slot connector 14 will move to the same height as the card ball 10, and then the downward squeezing force on the pressing plate 2 is released. At this time, the spring 12 loses its extrusion force and begins to rebound, driving the movable block 13 to move upward, and the vertical plane of the inner wall of the movable block 13 is used to push the card ball 10 to move to the card groove of the outer wall of the card groove connecting piece 14, so that the card ball 10 is used to fix the card groove connecting piece 14, and at the same time, the vertical plane of the inner wall of the movable block 13 is used to squeeze and block the card ball 10, ensuring that the card ball 10 can always remain in the card groove of the outer wall of the card groove connecting piece 14, thereby realizing the installation connection between the slide body 4 and the base plate 1. When disassembly is required, press the pressing plate 2 again, and use the pressing plate 2 to move the vertical plane of the inner wall of the movable block 13 away from the outer wall of the card ball 10, The groove connector 14 is moved out from the inside of the base plate 1, thereby realizing the disassembly of the slide body 4, improving the installation and disassembly efficiency of the slide body 4, and at the same time enhancing the stability of the connection of the slide body 4, avoiding the unstable connection between the base plate 1 and the slide body 4 and shaking, thereby affecting the movement accuracy of the base plate 1. When the slide body 4 moves to the outer wall of the track, the balls 16 inside the slide body 4 will squeeze the slide rail plates 2 6 on both sides. The slide rail plates 2 6 will drive the rubber plate 7 to compress synchronously and move the connecting block 1 17 while squeezing. The connecting block 17 will drive the rotating plate 18 to rotate through the rotating shaft 1 15 while moving, thereby driving the connecting block 2 19 through the rotating shaft 2 23. When the connecting block 19 moves, the connecting block 19 will be driven to slide on the outer wall of the limiting column 21. The limiting column 21 is used to limit and guide the movement of the connecting block 19. When the connecting block 19 moves, the spring 22 will be driven to stretch. According to the elastic characteristics of the spring 22, the spring 22 will have a recovery force during the stretching process. This force will be transmitted to the outer wall of the slide plate 26, so that the slide plate 26 is used to squeeze the outer wall of the ball 16, thereby reducing the connection gap between the slide plate 26 and the ball 16, thereby avoiding the situation where the slide body 4 produces a certain displacement due to inertia during the stopping process, and improving the accuracy of the equipment guidance.
