Description

Technical Field

[0001] This invention belongs to the field of linear guide technology, specifically relating to a linear guide with improved load-bearing capacity. Background Technology

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Based on the nature of friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides, among others.

[0003] Publication number "CN110454499B" discloses "a linear guide rail," comprising a mounting base, a guide rail mounting component, a push block, an arc-shaped guide rail mounting plate, a cylindrical guide rail mounting plate, a cylindrical guide rail fixing block, a cylindrical guide rail, a slider, a horizontal plate, a top plate, a vertical plate, a connecting shaft, a positioning bolt, a cleaning mechanism, an arc-shaped bearing, a limiting post, an arc-shaped guide rail, an oil pump, an oil tank, a tee pipe, an oil inlet connector, a limiting groove, an oil passage, an oil drip hole, a threaded rod, a bearing, a cotton cloth cleaning block, an arc-shaped plate, and a screw cap. When wear causes wobbling during sliding, the position of the arc-shaped guide rail can be adjusted by pushing the push block. After the arc-shaped bearing and the arc-shaped guide rail are in close contact, the slider can run stably, allowing the device to continue to be used without replacement, greatly improving the device's service life and reducing its operating costs. The device includes a cleaning mechanism and a lubrication mechanism, greatly facilitating the cleaning and lubrication of the arc-shaped guide rail surface.

[0004] In existing technology, the slider surface in a traditional linear guide is used to mount objects. The slider moves within the track, which in turn moves the objects. However, the slider usually generates downward pressure during its movement. Excessive pressure can easily cause track deformation or damage. This invention proposes a scheme to propel the slider by air jets, so that the slider receives a certain amount of upward thrust during its sliding within the track, thereby improving the track's load-bearing capacity and preventing the downward pressure of the slider from acting directly on the track. Summary of the Invention

[0005] The purpose of this invention is to provide a linear guide rail with improved load-bearing capacity, aiming to solve the problem in the prior art where the slider surface of the traditional linear guide rail is used to mount objects, and the slider moves within the rail to drive the movement of the objects. However, the slider usually generates downward pressure during the movement, and excessive pressure can easily cause the rail to deform or be damaged.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figures 1-12 The present invention provides the following technical solutions:

[0044] A linear guide rail with improved load-bearing capacity includes:

[0045] Track body 1, with a sliding groove 10 inside the track body 1;

[0046] The slider body 201 is slidably connected to the slide groove 10.

[0047] Multiple connecting holes 3 are provided, and all multiple connecting holes 3 are opened on the lower inner wall of the slide groove 10;

[0048] Multiple air push grooves 203 are provided, and multiple air push grooves 203 are all opened at the lower end of the slider body 201;

[0049] Cylinder 104 is mounted on the underside of track body 1 via a support assembly;

[0050] The pneumatic propulsion assembly is provided in multiple sets, each set of pneumatic propulsion assemblies is respectively located in multiple connection holes 3. Each set of pneumatic propulsion assemblies includes a limiting plate 301, an exhaust pipe 302, a bellows 303 and an electric control valve 304. The limiting plate 301 is fixedly connected to the inner wall of the connection hole 3. The exhaust pipe 302 is rotatably connected to the inner walls on both sides of the limiting plate 301 through a rotating shaft 4. The electric control valve 304 is fixedly connected to the inner wall of the connection hole 3. One end of the bellows 303 is fixedly connected to one end of the exhaust pipe 302, and the other end of the bellows 303 is fixedly connected to the output end of the cylinder 104. The electric control valve 304 is connected to the bellows 303.

[0051] In a specific embodiment of the present invention, the slide groove 10 opened in the track body 1 is used to limit the slider body 201. The slider body 201 moves within the slide groove 10 by means of a pneumatic propulsion assembly. The drive assembly is controlled to operate according to the running direction, so that the exhaust pipe 302's output jet end turns to one side of its moving direction. When the sensor 305 is directly above the electronic control valve 304, the sensor 305 sends an opening signal to the corresponding electronic control valve 304. The electronic control valve 304 opens, and the airflow generated by the cylinder 104 enters the pneumatic propulsion groove 203 through the bellows 303 and the exhaust pipe 302. The airflow ejected from the exhaust pipe 302 pushes the slider body 201 to move. The pushing force is decomposed into a horizontal pushing force and a vertical upward pushing force, pushing the slider body 201 to move upward, which cancels out the pressure of the object on the slider body 201, effectively improving the load-bearing capacity of the slider body 201. Compared with traditional linear guides, it avoids all the pressure on the slider acting on the track, thus preventing damage to the track.

[0052] Please refer to the details. Figures 1-12 One end of each of the multiple rotating shafts 4 extends through one side of the track body 1 and outwards. A drive assembly is provided on one side of the track body 1, and the drive assembly is connected to the multiple rotating shafts 4.

[0053] In this embodiment, the three exhaust pipes 302 in the same row are connected by a rotating shaft 4, the output direction of the exhaust pipes 302 is controlled by the rotating shaft 4, and the drive assembly drives multiple rotating shafts 4 to rotate.

[0054] Please refer to the details. Figures 1-12 The drive assembly includes a pulley, a belt 401, a bracket 402, and a motor 403. There are multiple pulleys. The bracket 402 is fixedly connected to one side of the track body 1. The multiple pulleys are respectively fixedly connected to the circumferential surfaces of multiple rotating shafts 4. The belt 401 is connected to the circumferential surfaces of the multiple pulleys. The motor 403 is fixedly connected to the surface of the bracket 402. The output end of the motor 403 is fixedly connected to one end of one of the rotating shafts 4.

[0055] In this embodiment: the bracket 402 in the drive assembly serves to mount the motor 403. When the motor 403 is running, it drives a rotating shaft 4 connected to its output end to rotate. The circumferential surfaces of multiple rotating shafts 4 are connected by a rotating wheel and a belt 401. The motor 403 drives multiple rotating shafts 4 to rotate. Each rotating shaft 4 controls the rotation of three exhaust pipes 302. The position of the paint spraying end of the exhaust pipe 302 is towards the moving direction of the slider body 201.

[0056] Please refer to the details. Figures 1-12 The slide groove 10 is trapezoidal, and the slider body 201 matches the slide groove 10. The slider body 201 slides within the slide groove 10 without disengaging.

[0057] In this embodiment, the slide groove 10 is set in a trapezoidal shape to limit the slider body 201 and prevent the slider body 201 from detaching from the slide groove 10.

[0058] Please refer to the details. Figures 1-12 The support assembly includes a support block 101, a base 102, and a fixing frame 103. There are two support blocks 101, and both support blocks 101 are fixedly connected to the lower end of the track body 1. The base 102 is fixedly connected to the lower end of the two support blocks 101. The fixing frame 103 is fixedly connected inside the base 102. The cylinder 104 is fixedly connected inside the fixing frame 103.

[0059] In this embodiment: the support block 101 in the support assembly serves to connect the track body 1 and the base 102. The base 102 is equipped with a fixing frame 103, which serves to fix the cylinder 104.

[0060] Please refer to the details. Figures 1-12 Sensors 305 are fixedly connected to the inner walls of multiple air-push grooves 203.

[0061] In this embodiment: the slider body 201 slides in the slide groove 10. When the air push groove 203 is connected to the connection hole 3, the sensor 305 controls the electric control valve 304 in the connection hole 3 to open. The airflow is ejected through the bellows 303 and the exhaust pipe 302, pushing the slider body 201 to move.

[0062] Please refer to the details. Figures 1-12A sealing gasket 202 is fixedly connected to the lower end of the slider body 201.

[0063] In this embodiment, the sealing gasket 202 is made of ceramic material with a smooth lower surface, which improves the sealing performance of the air-push groove 203 and the connecting hole 3.

[0064] Please refer to the details. Figures 1-12 The upper end of the slider body 201 is fixedly connected to the mounting block 2.

[0065] In this embodiment: the upper end of the mounting block 2 is provided for mounting items.

[0066] Please refer to the details. Figures 1-12 The limiting plate 301 is in the shape of an inverted trapezoid, which serves to limit the exhaust pipe 302.

[0067] In this embodiment, the exhaust pipe 302 rotates around the pivot 4. When the exhaust pipe 302 rotates clockwise or counterclockwise until it contacts the inner wall of the limiting plate 301, it can no longer rotate.

[0068] Please refer to the details. Figures 1-12 The exhaust pipe 302 rotates at a certain angle around the pivot 4, and the cylinder 104 runs to generate airflow. The airflow passes through the bellows 303 and the exhaust pipe 302 and is ejected into the air thrust groove 203 through jet injection, which drives the slider body 201 to move.

[0069] In this embodiment: when the exhaust pipe 302 ejects airflow, the resulting thrust is decomposed into horizontal and vertical thrust. The horizontal thrust pushes the slider body 201 to move, and the vertical thrust is used to improve the load-bearing capacity of the slider body 201. The airflow magnitude and the magnitude of the generated thrust are controlled by the cylinder 104.

[0070] The cylinder 104, electronic control valve 304, sensor 305 and motor 403 used in this solution are all existing technologies. Different models can be selected according to actual needs, and will not be elaborated on here.

[0071] The working principle and usage process of this invention are as follows: In use, the drive assembly is first controlled according to the moving direction of the slider body 201. The drive assembly drives multiple rotating shafts 4 to rotate, and the rotating shafts 4 control the jet direction of the exhaust pipe 302. When the exhaust pipe 302 is connected to the connecting hole 3, the sensor 305 sends a signal. Upon receiving the signal, the electronic control valve 304 opens, and the airflow passes through the bellows 303 and the exhaust pipe 302, then sprays into the air-push groove 203, driving the slider body 201 to move. The airflow generates thrust and load-bearing capacity, preventing the slider body 201 from pressing down on the slide groove 10 and causing deformation or damage to the slide groove 10. By using this device, the movement of the slider body 201 is controlled by the airflow. The tilted airflow is used to push the slider body 201 to move, while simultaneously increasing the load-bearing capacity of the slider body 201, preventing excessive pressure on the slider body 201 from damaging the slide groove 10, and improving the service life of the linear track.
