Description
Technical Field
[0001] The utility model relates to the technical field of linear guide rails, in particular to an anti-collision linear slide rail. Background Art
[0002] Linear slides, also known as linear slides or slide rails, are an important mechanical foundation. Their main function is to support and guide moving parts to perform reciprocating linear motion along a predetermined trajectory. Linear slides are mainly composed of two parts: tracks and sliders. The track provides a path for the slider to move, and the slider is installed on the track to achieve linear reciprocating motion by sliding. Linear slides are widely used in mechanical manufacturing, automated production lines, aerospace, precision instruments and other fields. In these fields, linear slides, as key components for achieving precise motion and positioning, play an irreplaceable role. At the same time, the high efficiency and durability of linear slides also make them an important part of many automated machinery. For example, linear slides are used in machine tools, bending machines, laser welding machines and other equipment.
[0003] However, when traditional linear slides move at high speeds or are impacted by external forces, the slide seat is prone to collision with objects at the end of the track, causing equipment damage or shutdown, affecting production efficiency. In addition, the collision may also generate noise and vibration, causing adverse effects on the working environment and user health.
[0004] Chinese patent document CN213684963U discloses a slide rail that is easy to install, including a device body, the device body includes a fixed seat, a first slide rail seat and a second slide rail seat, one side of the top of the fixed seat is provided with a first slide rail seat, the other side of the top of the fixed seat is provided with a second slide rail seat, the bottom ends of the first slide rail seat and the second slide rail seat are both provided with a mounting mechanism, the mounting mechanism includes a slot and a first connecting plate, the bottom ends of the first slide rail seat and the second slide rail seat are both fixed with an insert block, the interior of the fixed seat is provided with a slot that cooperates with the insert block, one side of the insert block is fixed with a card block, a side of the inner wall of the slot close to the card block is fixed with a limit block, and the limit block is inserted into the card block, and the first connecting plate is provided at the middle position of the first slide rail seat and the second slide rail seat; but there are still the following defects in the implementation process:
[0005] Although the device in the above document facilitates the installation of the first slide rail seat and the second slide rail seat without the need to tighten multiple sets of bolts, and if the first bolt is slightly loosened, it will not significantly affect the fixation of the first slide rail seat and the second slide rail seat, but during the use of the device in the above document, when the slider moves quickly on the guide rail body, when it slides to the end of the guide rail, it may collide with the limit block or other objects at the end of the guide rail body. If the collision is serious, it is easy to cause the slider or the collided object to be broken or damaged, affecting the normal use of the linear slide rail. Utility Model Content
[0006] The purpose of the utility model is to provide an anti-collision linear slide rail to solve the problems raised in the above background technology.
[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0008] A collision-proof linear slide rail comprises a slide rail body; a slider body is slidably connected to the upper part of the slide rail body, the slider body comprises an upper connecting block 2 and two slider assemblies 2, the upper parts of the two slider assemblies 2 are mutually engaged with the lower part of the upper connecting block 2, a positioner is fixedly connected to one side of the upper connecting block 2, a plurality of connecting grooves 2 are opened on the upper part of the upper connecting block 2, a buffer structure 1 is fixedly connected to the inner cavities of the plurality of connecting grooves 2, a magnet 1 is symmetrically fixedly connected to the middle part of the upper connecting block 2, a plurality of buffer structures 1 on the same side are fixedly connected to a foam plate, and an anti-collision structure is fixedly connected to one side of the slide rail body.
[0009] A further improvement of the technical solution of the utility model is that: a plurality of connecting grooves 1 are opened on the upper part of the slide rail body, the inner cavities of the plurality of connecting grooves 1 are all fixedly connected with spring pieces, and an arc-shaped slide bar is symmetrically fixedly connected with the middle part of the slide rail body.
[0010] The above-mentioned technical solution is adopted. In this solution, a connecting spring sheet is fixed in the inner cavity of the connecting groove 1, so that the spring sheet can be used to slow down the movement of the slider body. The spring sheet will undergo elastic deformation when subjected to external force and store energy. When the slider body moves on the slide rail body and approaches the connecting groove 1, the slider body will compress the spring sheet, causing the spring sheet to deform and store energy. As the slider body continues to move, the energy stored in the spring sheet will gradually be released, and a reverse force will be applied to the spring sheet through its restoring force. This reverse force is opposite to the moving direction of the slider body, so that the moving speed of the slider body can be slowed down. When the slider body completely passes through the connecting groove 1, the spring sheet returns to its original state and waits for the next compression and release process.
[0011] A further improvement of the technical solution of the utility model is that the slider assembly 2 includes a lower connecting block 1, the upper part of the lower connecting block 1 is threadedly connected with a plurality of bolts, the lower part of the upper connecting block 2 is threadedly connected with the plurality of bolts, and a pulley is rotatably connected to a lower end of the lower connecting block.
[0012] The above-mentioned technical solution is adopted, in which the positions of the slider assembly 2 and the upper connecting block 2 can be further connected through the cooperation of the bolts and the upper connecting block 2, so as to prevent the slider assembly 2 and the upper connecting block 2 from separating during use, thereby affecting the normal use of the device, and the positions of the slider assembly 2 and the upper connecting block 2 are further limited by a number of bolts. When the slider assembly 2 or the upper connecting block 2 is severely worn during use, the bolts can be rotated to release the position limitation of the slider assembly 2 and the upper connecting block 2, thereby facilitating the replacement of the slider assembly 2 or the upper connecting block 2, thereby reducing the maintenance cost of the device.
[0013] A further improvement of the technical solution of the utility model is that a buffer structure 1 includes an outer shell, the outer surface of the outer shell is fixedly connected to the inner cavity of the connecting groove 2, an elastic column is slidably connected to the inner cavity of the outer shell, a side of the elastic column close to the bottom wall of the inner cavity of the outer shell is fixedly connected to a spring 1 together with the bottom wall of the inner cavity of the outer shell, and a side of the elastic column away from the bottom wall of the inner cavity of the outer shell is fixedly connected to the foam board.
[0014] The above technical solution is adopted. In this solution, when spring 1 is in an unstressed state, it will push the elastic column to maintain an initial position in the inner cavity of the shell. The elastic column is fixedly connected to the foam board, so it further pushes the foam board to move, so that the foam board is also in an initial position determined by the elastic force of the spring. When the foam board is acted upon by an external force and moves, the external force will act in the opposite direction to the elastic column through the same path, causing the elastic column to slide in the inner cavity of the shell. As the elastic column slides, the spring that was originally in an extended state begins to contract and store elastic potential energy. In this process, part of the work done by the external force is converted into the elastic potential energy of spring 1, thereby being able to buffer the external force applied to the foam board and prevent the slider body from colliding with other structures, thereby causing damage to the device.
[0015] A further improvement of the technical solution of the utility model is that the anti-collision structure includes a connecting block three, a side of the connecting block three close to the slider body is fixedly connected to a rubber block one, an upper part of the connecting block three close to the rubber block one is symmetrically fixedly connected to a buffer structure two, a lower part of the connecting block three close to the rubber block one is symmetrically fixedly connected to a buffer structure three, and the middle part of the connecting block three and the middle part of the rubber block one are jointly fixedly connected to a magnetic blocking structure.
[0016] According to the above technical solution, since the rubber block 1 is made of rubber material, when the device collides with other objects or structures, the rubber block 1 made of rubber material can effectively absorb and disperse the impact force generated by the collision. The elasticity of rubber enables it to deform quickly and absorb energy, thereby reducing the damage to the device itself and other related components caused by the collision.
[0017] A further improvement of the technical solution of the utility model is that the buffer structure 2 includes a circular block, the circular block is fixedly connected to the connecting block 3, a side of the circular block away from the connecting block 3 is fixedly connected to a spring 2, and a side of the spring 2 away from the circular block is fixedly connected to a rubber block 2.
[0018] By adopting the above technical solution, when the rubber block 2 is hit, the spring 2 can be deformed quickly to absorb the impact force generated by the collision. In this process, the spring 2 converts part of the impact energy into its own elastic potential energy, thereby reducing the impact energy directly transmitted to the rubber block 2.
[0019] A further improvement of the technical solution of the utility model is that the magnetic blocking structure includes an inductor, one side of the inductor is fixedly connected to a controller, the upper part of the controller is fixedly connected to a connecting tube, the side of the connecting tube away from the controller is fixedly connected to an electromagnetic block, and the side of the electromagnetic block away from the slider body is fixedly connected to a battery.
[0020] The above technical solution is adopted, in which the position of the locator is sensed by a sensor, and then when the distance between the slider body and the anti-collision structure is too close, the controller will control the operation of the electromagnetic block. When the electromagnetic block is running, a large amount of magnetic force opposite to magnet one will be generated, so that under the action of magnetic repulsion, the slider body and the anti-collision structure can be effectively prevented from getting closer, thereby preventing the slider body from colliding with the anti-collision structure.
[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0022] 1. The utility model provides an anti-collision linear slide rail, which can support and connect the slider body through the slide rail body, and can slow down the speed of the slider body during the movement of the slider body. Through the cooperation of the foam plate and the buffer structure one, the buffer structure one can be used to absorb the external force on the foam plate, so that when the slider body collides, the damage to the slider body can be reduced. Through the cooperation of the anti-collision structure and the magnet one, when the slider body and the anti-collision structure are close to each other, magnetic repulsion can be used, thereby effectively preventing the slider body and the anti-collision structure from further approaching each other, and effectively preventing the slider body from colliding with the anti-collision structure.
[0023] 2. The utility model provides an anti-collision linear slide rail, which is threadedly connected to the upper connecting block 2 by bolts, and threadedly connected to the lower connecting block 1 by bolts, so that the connection between the slider assembly 2 and the upper connecting block 2 can be further limited by bolts to prevent the slider assembly 2 and the upper connecting block 2 from detaching from each other during operation, and to facilitate the disassembly of the slider assembly 2 and the upper connecting block 2, thereby reducing the maintenance cost of the device.

DETAILED DESCRIPTION
[0034] The present invention is further described in detail below in conjunction with the embodiments:
[0035] Example 1
[0036] like Figure 1-8As shown, the utility model provides an anti-collision linear slide rail, including a slide rail body 1; a slider body 2 is slidably connected to the upper part of the slide rail body 1, the slider body 2 includes an upper connecting block 23 and two slider components 21, the upper parts of the two slider components 21 are mutually engaged with the lower part of the upper connecting block 23, a positioner 22 is fixedly connected to one side of the upper connecting block 23, a plurality of connecting grooves 24 are opened on the upper part of the upper connecting block 23, and the inner cavities of the plurality of connecting grooves 24 are all fixedly connected to buffer structures 25, a magnet 26 is symmetrically fixedly connected to the middle part of the upper connecting block 23, a plurality of buffer structures 25 on the same side are commonly fixedly connected to a foam plate 27, and an anti-collision structure 3 is fixedly connected to one side of the slide rail body 1.
[0037] In this embodiment, the slide rail body 1 can be used to support and connect the slider body 2 when it moves, and the slide rail body 1 can be used to slow down the moving speed of the slider body 2. The upper connecting block 23 can be supported and connected by the slider assembly 21. The position of the slider body 2 can be positioned by the locator 22, so that the anti-collision structure 3 can sense the position of the slider body 2. The external force applied to the foam plate 27 can be buffered and reduced by the cooperation of the connecting groove 24 and the buffer structure 1 25. The position distance between the slider body 2 and the anti-collision structure 3 can be limited by the cooperation of the anti-collision structure 3 and the magnet 1 26 to prevent the slider body 2 from being too close to the anti-collision structure 3. The external force applied to the slider body 2 can be buffered by the foam plate 27, and the anti-collision structure 3 can prevent the slider body 2 from colliding with other structures.
[0038] Example 2
[0039] like Figure 2 , Figure 4 , Figure 8 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the slider assembly 21 includes a lower connecting block 211, the upper portion of the lower connecting block 211 is threadedly connected to a plurality of bolts 212, the lower portion of the upper connecting block 23 is threadedly connected to the plurality of bolts 212, the lower end of the lower connecting block 211 is rotatably connected to a pulley 213, the magnetic blocking structure 35 includes a sensor 351, one side of the sensor 351 is fixedly connected to a controller 352, the upper portion of the controller 352 is fixedly connected to a connecting pipe 353, the side of the connecting pipe 353 away from the controller 352 is fixedly connected to an electromagnetic block 354, and the side of the electromagnetic block 354 away from the slider body 2 is fixedly connected to a battery 355.
[0040] In this embodiment, the slider assembly 21 is first engaged with the upper connecting block 23, and then the positions of the slider assembly 21 and the upper connecting block 23 are connected by using a plurality of bolts 212, and then the slider body 2 is allowed to slide on the slide rail body 1. During the movement, the outer surface of the pulley 213 will contact the outer surface of the arc-shaped slide bar 13. When the slider body 2 slides rapidly toward the anti-collision structure 3, the position of the locator 22 can be sensed by the sensor 351 first, and then the position of the slider body 2 on the slide rail body 1 is judged. When the sensor 351 senses that the distance between the slider body 2 and the anti-collision structure 3 is too close, the sensing data will be transmitted to the controller 352, and then the controller 352 will control the operation of the electromagnetic block 354 through the connecting pipe 353, and the electromagnetic block 354 will be powered by the battery 355. When the electromagnetic block 354 is running, a magnetic force that repels the magnet 1 26 will be generated, and the magnet 1 26 can be repelled by this magnetic force, and then the moving speed of the slider body 2 is reduced by the magnet 1 26.
[0041] Example 3
[0042] like Figure 3 As shown, based on Example 2, the utility model provides a technical solution: preferably, a plurality of connection grooves 11 are opened on the upper part of the slide rail body 1, and the inner cavities of the plurality of connection grooves 11 are fixedly connected with spring pieces 12, and the middle part of the slide rail body 1 is symmetrically fixedly connected with an arc-shaped slide bar 13.
[0043] In this embodiment, when the slider body 2 slides toward the anti-collision structure 3, when the lower part of the upper connecting block 23 contacts the inner cavity of the connecting groove 11, the upper connecting block 23 will exert a force on the spring piece 12 in the inner cavity of the connecting groove 11, causing the spring piece 12 to deform and store energy. As the slider body 2 continues to move, the energy stored in the spring piece 12 will gradually be released, and a reverse force will be exerted on the spring piece 12 through its restoring force. This reverse force is opposite to the moving direction of the slider body 2, and thus the moving speed of the slider body 2 can be further slowed down.
[0044] Example 4
[0045] like Figure 5 , Figure 6 , Figure 7 As shown, on the basis of Example 3, the utility model provides a technical solution: preferably, the buffer structure 1 25 includes a shell 251, the outer surface of the shell 251 is fixedly connected to the inner cavity of the second connection groove 24, the inner cavity of the shell 251 is slidably connected with an elastic column 253, the side of the elastic column 253 close to the bottom wall of the inner cavity of the shell 251 is fixedly connected with a spring 1 252 together with the bottom wall of the inner cavity of the shell 251, and the side of the elastic column 253 away from the bottom wall of the inner cavity of the shell 251 is fixedly connected to the foam plate 27;
[0046] The anti-collision structure 3 includes a connecting block three 31, a rubber block one 32 is fixedly connected to one side of the connecting block three 31 close to the slider body 2, a buffer structure two 33 is symmetrically fixedly connected to the upper part of the connecting block three 31 close to the rubber block one 32, a buffer structure three 34 is symmetrically fixedly connected to the lower part of the connecting block three 31 close to the rubber block one 32, a magnetic blocking structure 35 is fixedly connected to the middle part of the connecting block three 31 and the middle part of the rubber block one 32, and the buffer structure two 33 includes a circular block 331, the circular block 331 is fixedly connected to the connecting block three 31, a spring two 332 is fixedly connected to one side of the circular block 331 away from the connecting block three 31, and a rubber block two 333 is fixedly connected to one side of the spring two 332 away from the circular block 331.
[0047] In this embodiment, when the slider body 2 collides with the anti-collision structure 3, the slider body 2 is first decelerated, and the speed of the slider body 2 has been reduced, so the kinetic energy and impact force during the collision will also be reduced accordingly. Then, when the slider body 2 collides with the anti-collision structure 3, the anti-collision structure 3 will apply a force to the foam plate 27 to push the foam plate 27 to move toward the upper connecting block 23, and then the foam plate 27 will push the elastic column 253 to slide in the inner cavity of the shell 251. As the elastic column 253 slides, the spring 1 252, which was originally in an extended state, begins to contract, storing elastic potential energy. In this process, part of the work done by the external force is converted into the elastic potential energy of the spring 1 252, so that the external force on the foam plate 27 can be buffered, and the damage to the slider body 2 caused by the impact of the collision is reduced; when a collision occurs, the slider body 2 will exert a force on the rubber block 2 333, pushing the rubber block 2 333 to move toward the circular block 331, and then drive the spring 2 332 to contract to absorb the impact force caused by the collision. At the same time, the rubber block 1 32 can effectively absorb and disperse the impact force caused by the collision, reducing the damage to the anti-collision structure 3 caused by the impact caused by the collision.
[0048] The following is a detailed description of the working principle of the anti-collision linear slide.
[0049] like Figure 1-8As shown, when in use, firstly, the slider assembly 21 is engaged with the upper connecting block 23, and then the positions of the slider assembly 21 and the upper connecting block 23 are connected by a plurality of bolts 212, and then the slider body 2 is allowed to slide on the slide rail body 1. During the movement, the outer surface of the pulley 213 will contact the outer surface of the arc-shaped slide bar 13. When the slider body 2 slides rapidly toward the anti-collision structure 3, the position of the locator 22 can be sensed by the sensor 351, and then the slider body 2 is judged. At the position on the slide rail body 1, when the sensor 351 senses that the distance between the slider body 2 and the anti-collision structure 3 is too close, the sensing data will be transmitted to the controller 352, and then the controller 352 will control the operation of the electromagnetic block 354 through the connecting pipe 353, and the battery 355 will provide power to the electromagnetic block 354. When the electromagnetic block 354 is running, it will generate a magnetic force that repels the magnet 1 26, and the magnet 1 26 can be repelled by this magnetic force, and then the moving speed of the slider body 2 is reduced by the magnet 1 26;
[0050] When the slider body 2 slides toward the anti-collision structure 3, when the lower part of the upper connecting block 23 contacts the inner cavity of the connecting groove 11, the upper connecting block 23 will apply a force to the spring sheet 12 in the inner cavity of the connecting groove 11, causing the spring sheet 12 to deform and store energy. As the slider body 2 continues to move, the energy stored in the spring sheet 12 will be gradually released, and a reverse force will be applied to the spring sheet 12 through its restoring force. This reverse force is opposite to the moving direction of the slider body 2, so the moving speed of the slider body 2 can be further slowed down.
[0051] When the slider body 2 collides with the anti-collision structure 3, the slider body 2 is first decelerated, and the speed of the slider body 2 has been reduced, so the kinetic energy and impact force during the collision will also be reduced accordingly. Then, when the slider body 2 collides with the anti-collision structure 3, the anti-collision structure 3 will apply a force to the foam plate 27 to push the foam plate 27 to move toward the upper connecting block 23, and then the foam plate 27 will push the elastic column 253 to slide in the inner cavity of the shell 251. As the elastic column 253 slides, the spring 1 252, which was originally in an extended state, begins to contract to store elastic potential energy. During the collision, part of the work done by the external force is converted into the elastic potential energy of the spring 1 252, so that the external force on the foam plate 27 can be buffered, and the damage to the slider body 2 caused by the impact of the collision is reduced; when a collision occurs, the slider body 2 will exert a force on the rubber block 2 333, pushing the rubber block 2 333 to move toward the circular block 331, and then drive the spring 2 332 to contract to absorb the impact force generated by the collision. At the same time, the rubber block 1 32 can effectively absorb and disperse the impact force generated by the collision, reducing the damage to the anti-collision structure 3 caused by the impact generated during the collision.
[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
