Description

Technical Field

[0001] This invention belongs to the field of linear guidance technology, specifically a linear guidance device. Background Technology

[0002] In the internal structure of mechanical structures or molds, in order to ensure their operational accuracy and smoothness, a guide assembly is usually set between two moving parts. Common guide assemblies usually consist of cylindrical guide posts, balls, and cylindrical guide sleeves. The balls act as frictional rolling components between the guide posts and the guide sleeves, causing the guide posts and guide sleeves to move relative to each other to achieve the guiding effect.

[0003] However, in some equipment, it may be necessary to move one component to a distant position to work with another structure. In this case, due to the length limitations of existing technology, it is not possible to guide the work well, which may lead to unstable movement. Consequently, some mechanisms in the equipment may not be able to properly connect with other structural parts and work together. For this reason, we have provided a linear guide device. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a linear guide device, which solves the problem that in some devices, it may be necessary to move one component to a distant position to cooperate with another structure. Due to the length limitations of the prior art, the guiding work cannot be performed well, and the movement may be unstable.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a linear guide device, including a skeleton assembly, and a transfer assembly that moves horizontally inside the skeleton assembly. A reinforcing assembly is fixedly mounted on the top of the transfer assembly. There are two reinforcing assemblies, with another reinforcing assembly disposed on the top of the skeleton assembly. The reinforcing assembly is used to fix its position relative to the transferred mechanism.

[0006] The frame assembly includes a shell, inside which a guide rod is fixedly installed, and inside which an air supply pipe is fixedly installed. Inside the air supply pipe, a bellows is connected via a spring. A limiting tube is fitted around the outside of the air supply pipe and the bellows. A second bellows is fixedly installed on the outside of the air supply pipe, and an air supply box is fixedly installed on the outside of the bellows. Inside the air supply box, a pressure plate slides vertically, with one side of the pressure plate located outside the air supply box. Both reinforcing components are fitted around the outside of the guide rod.

[0007] Preferably, the transfer assembly includes a second air delivery box fixed to the outside of the second bellows. Two guide plates are hinged to both sides of the second air delivery box. The two sides of the two guide plates are connected by two bidirectional telescopic rods. The bidirectional telescopic rods slide vertically on the outside of the second air delivery box. An arc-shaped spring telescopic rod is slidably installed on the side of the guide plate. The arc-shaped spring telescopic rod passes through the outside of the second air delivery box and is hinged to a limit plate. The inside of the second air delivery box is connected to a sealing plate by a tension spring.

[0008] Preferably, the transfer assembly further includes a high-position plate fixed to the top of the tension spring, and a guide plate is connected to the top of the sealing plate via a spring telescopic rod. The guide plate is snapped into the inner wall of the second air delivery box and extends and retracts inside the sealing plate.

[0009] Preferably, the sealing plate and the high-position plate together divide the gas delivery box into two independent chambers. The gas delivery box is connected to the inside of the gas delivery pipe. The top of the pressurizing plate and the outer side of the pusher plate are on the same horizontal line.

[0010] Preferably, the air delivery box moves towards the air delivery pipe, which compresses the corrugated pipe and the spring. Air enters the interior of the corrugated pipe through the air delivery pipe, and the corrugated pipe pushes the conveying assembly closer to the air delivery box.

[0011] Preferably, the reinforcement assembly includes a sliding tube fixed to the top of the gas delivery box two, there are two sliding tubes, and another sliding tube is set on the top of the pressure plate. The outer side of the sliding tube is connected to a reinforcement plate by a spring two. There are several reinforcement plates and spring twos distributed in a ring at equal angles on the outer side of the sliding tube. The inner wall of the sliding tube is sleeved with a guide rod by a ball bearing. The two sides of the sliding tube are connected to two bellows three by two spring threes.

[0012] Preferably, the corrugated pipe three is connected to the interior of the sliding pipe, and the interior of the sliding pipe has a slot for the movable reinforcing plate. Each slot is interconnected and eventually connected to the interior of the air delivery box two.

[0013] Preferably, the interior of the bellows third is filled with lubricating oil, and the interior of the sliding tube is used to connect the groove of the bellows third, which eventually comes into contact with the outside of the ball.

[0014] Preferably, the two bellows are in contact and press against each other, and the lubricating oil inside them contacts the outside of the ball through the groove inside the sliding tube. The sliding tube moves horizontally outside the guide rod, and the ball is driven to rotate, and the lubricating oil coats the outside of the ball.

[0015] Preferably, the interior of the sliding tube is connected to the gas delivery box, and the pressurizing plate divides the interior of the gas delivery box into two independent chambers.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention, through the cooperation of structures such as the skeleton assembly and the transfer assembly, allows the mechanism to begin its transfer operation when it is fitted onto any of the reinforcing components. When it moves to the left, the right-side reinforcing component fixes its position relative to the mechanism by the compression of the internal airflow. Due to the expandable nature of the first and second bellows, the two reinforcing components move towards each other. When the two reinforcing components come into contact, the left-side reinforcing component is engaged and its position relative to the mechanism is fixed. The guide rod remains fixed. This structure enables the mechanism to perform transfer operations more quickly and stably. The lengths of the outer shell and the guide rod can also be adjusted according to actual conditions. The structures other than the outer shell and the guide rod can be arranged equidistantly inside the device.

[0018] This invention, through the cooperation of structures such as reinforcement components and skeleton components, allows the two bellows to abut and compress each other when two reinforcement components come into contact. The lubricating oil inside the bellows flows through the groove inside the sliding tube and finally contacts the outside of the ball bearing. As the ball bearing rolls, the lubricating oil coats the ball bearing, making the device work more smoothly. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] like Figures 1 to 9 As shown, the present invention provides a linear guide device, including a skeleton assembly 100 and a transfer assembly 200 that moves horizontally inside the skeleton assembly 100. A reinforcing assembly 300 is fixedly mounted on the top of the transfer assembly 200. There are two reinforcing assemblies 300, with another reinforcing assembly 300 disposed on the top of the skeleton assembly 100. The reinforcing assembly 300 is used to fix its position relative to the transferred mechanism.

[0031] The frame assembly 100 includes a housing 101, inside which a guide rod 102 is fixedly installed, and inside which an air supply pipe 106 is fixedly installed. Inside the air supply pipe 106, a bellows 105 is connected via a spring 108. A limiting tube 107 is fitted around the outside of the air supply pipe 106 and the bellows 105. A second bellows 109 is fixedly installed on the outside of the air supply pipe 106, and an air supply box 103 is fixedly installed on the outside of the bellows 105. Inside the air supply box 103, a pressure plate 104 slides vertically, with one side of the pressure plate located outside the air supply box 103. Both reinforcing components 300 are fitted around the outside of the guide rod 102.

[0032] The air delivery box 103 moves toward the air delivery pipe 106, which compresses the bellows 105 and the spring 108. Air enters the bellows 109 through the air delivery pipe 106, and the bellows 109 pushes the transfer assembly 200 toward the air delivery box 103.

[0033] By adopting the above scheme: when the device enters the working state, the design of the skeleton assembly 100 enables the two reinforcing assemblies 300 to move in opposite directions, thereby enabling the moved mechanism to move more quickly and smoothly. Through the cooperation of the transfer assembly 200 and the skeleton assembly 100, the reinforcing assemblies 300 can also clamp or loosen the mechanism at appropriate positions, further improving the stability of the device during operation.

[0034] like Figures 3-6 As shown, the transfer assembly 200 includes an air delivery box 201 fixed to the outside of the bellows 109. Two guide plates 203 are hinged to both sides of the air delivery box 201. The two sides of the two guide plates 203 are connected by two bidirectional telescopic rods 202. The bidirectional telescopic rods 202 slide vertically on the outside of the air delivery box 201. An arc-shaped spring telescopic rod 204 is slidably installed on the side of the guide plate 203. The arc-shaped spring telescopic rod 204 passes through the outside of the air delivery box 201 and is hinged to a limit plate 205. The inside of the air delivery box 201 is connected to a sealing plate 209 by a tension spring 210.

[0035] The transfer assembly 200 also includes a high plate 206 fixed to the top of the tension spring 210. The top of the sealing plate 209 is connected to a guide plate 208 via a spring telescopic rod 207. The guide plate 208 is snapped into the inner wall of the air delivery box 201 and extends and retracts inside the sealing plate 209.

[0036] The sealing plate 209 and the high-position plate 206 together divide the gas delivery box 201 into two independent chambers. The gas delivery box 201 is connected to the inside of the gas delivery pipe 106. The top of the pressurizing plate 104 and the outside of the pusher plate 203 are on the same horizontal line.

[0037] The above solution is adopted: when the institution is set up in "such as Figure 4As shown, when the left sliding tube 301 is outside, due to the engagement of the guide plate 208 and the second air box 201, the reinforcing plate 302 is pushed out by the airflow, that is, the outer side of the reinforcing plate 302 is in close contact with the inner wall of the mechanism. The mechanism drives the left reinforcing component 300 and the transfer component 200 to move to the right. During the movement of the reinforcing component 300, the bellows 109 can be extended, and the first air box 103 and the reinforcing component 300 on its top can move. At this time, the two reinforcing components 300 move towards each other, and the right reinforcing component 300 can more quickly meet the left reinforcing component 300 and the mechanism outside it. However, at this time, the pusher plate 203 will first contact the pressure plate 1. 04, and the pusher plate 203 folds down and pushes it down, drawing the air inside the right reinforcement component 300 into the air delivery box 103. The right reinforcement plate 302 retracts. At the same time, the pusher plate 203 also pushes the guide plate 208 through the arc spring telescopic rod 204 and the limit plate 205. The guide plate 208 is no longer engaged with the air delivery box 201. The tension spring 210 pulls the closing plate 209 down and draws the air inside the left reinforcement component 300 into the air delivery box 201. The left reinforcement plate 302 retracts and is no longer fixed. It can quickly and smoothly connect to the right reinforcement component 300. However, at this time, the airflow inside the skeleton component 100 is in a compressed state.

[0038] After the two reinforcing components 300 separate, the right reinforcing component 300 moves with the mechanism, releasing the compressed airflow and lifting the pressure plate 104, causing the right reinforcing plate 302 to extend and adhere tightly to the inner wall of the structure, thus fixing its position and preventing it from falling off the reinforcing component 300. When the right reinforcing component 300 moves to the left, the two sides re-engage, and the pusher plate 203 repeats the above actions. The mechanism engages with the left reinforcing component 300. When the left reinforcing component 300 moves, it drives the transfer component 200 to squeeze the bellows 109. Because the slot inside the air pipe 106 for air to enter the bellows 109 is narrow, the airflow... Instead of entering the gas supply pipe 106 in time, it will push the sealing plate 209 up. At this time, the guide plate 208 will re-engage with the gas supply box 201, and the left reinforcement component 300 will fix the position of the mechanism. The above process is repeated. When the reinforcement component 300 moves with the mechanism, it can always fix its position with the mechanism, which can make the mechanism more stable when moving through the device, and the moving distance is also longer. The length of the outer shell 101 and the guide rod 102 can also be adjusted according to the actual situation. The structures in the device other than the outer shell 101 and the guide rod 102 can be arranged at equal intervals inside, which further improves the applicability of the device.

[0039] like Figures 7-9As shown, the reinforcement component 300 includes a sliding tube 301 fixed to the top of the gas delivery box 201. There are two sliding tubes 301. Another sliding tube 301 is located on the top of the pressure plate 104. The outer side of the sliding tube 301 is connected to a reinforcement plate 302 by a spring 2 304. There are several reinforcement plates 302 and springs 2 304, which are distributed in a ring at equal angles on the outer side of the sliding tube 301. The inner wall of the sliding tube 301 is sleeved with the guide rod 102 by a ball bearing 305. The two sides of the sliding tube 301 are connected to two bellows 303 by two springs 306.

[0040] The corrugated pipe 303 is internally connected to the sliding pipe 301. The sliding pipe 301 has a slot for the movable reinforcing plate 302. Each slot is interconnected and eventually connected to the interior of the air delivery box 201.

[0041] The interior of the bellows 303 is filled with lubricating oil, and the interior of the slide tube 301 is used to connect the groove of the bellows 303, which eventually comes into contact with the outside of the ball 305.

[0042] Two bellows 303 come into contact and press against each other. The lubricating oil inside them comes into contact with the outside of the ball 305 through the groove inside the slide tube 301. The slide tube 301 moves horizontally outside the guide rod 102, and the ball 305 is driven to rotate. The lubricating oil coats the outside of the ball 305.

[0043] The interior of the sliding tube 301 is connected to the gas delivery box 103, and the pressurization plate 104 divides the interior of the gas delivery box 103 into two independent chambers.

[0044] The above solution involves the following: when the two reinforcing components 300 come into contact, the two bellows 303 also abut and are squeezed together. The lubricating oil inside the bellows 303 flows through the groove inside the sliding tube 301 and eventually contacts the outside of the ball bearing 305. As the ball bearing 305 rolls, the lubricating oil coats its entire surface, making the device work more smoothly. However, it should be noted that the lubricating oil inside the bellows 303 needs to be refilled periodically. The design of the number of ball bearings 305 makes it difficult for the sliding tube 301 to tilt when it moves through the guide rod 102, thus ensuring the stability of the device operation.

[0045] Working principle and usage process of this invention:

[0046] First, the outer casing 101 needs to be installed in a fixed position, and the mechanism that needs to be moved is attached to the outside of any of the sliding tubes 301, and then it can start working;

[0047] When the institution is set up, such as Figure 4When the device moves to the outside of the left sliding tube 301, the reinforcing plate 302 is pushed out by the airflow due to the engagement of the guide plate 208 and the second air box 201. This means the outer side of the reinforcing plate 302 is tightly against the inner wall of the mechanism. When the mechanism moves to the right, it drives the reinforcing component 300 and the conveying component 200 to move simultaneously. This structure ensures the smooth operation of the mechanism. Because the device is a sealed space, the movement of the reinforcing component 300 can extend the second bellows 109 and draw air from inside the first bellows 105, thereby moving the first air box 103 and the reinforcing component 300 on top of it. At this time, the two reinforcing components 300 move towards each other, allowing the right-side reinforcing component 300 to move more quickly. The left reinforcement component 300 and its external mechanism are welcomed, but at this time, the pusher plate 203 will first contact the pressure plate 104. The pusher plate 203 folds and pushes it down, drawing the air inside the right reinforcement component 300 into its interior. The right reinforcement plate 302 retracts, and the pusher plate 203 will also push the guide plate 208 through the limit plate 205. The guide plate 208 is no longer engaged with the air box 201. The tension spring 210 pulls the sealing plate 209 down, drawing the air inside the left reinforcement component 300 into its interior. The left reinforcement plate 302 retracts and is no longer fixed to the mechanism. It can quickly and smoothly connect to the right reinforcement component 300, but at this time the airflow inside the skeleton component 100 is in a compressed state.

[0048] When the two reinforcing components 300 separate, the compressed airflow is released and pushes up the pressure plate 104, causing the right reinforcing plate 302 to extend and stick tightly to the inner wall of the structure, thereby fixing its position and preventing it from falling off. When the right reinforcing component 300 moves to the left, the two sides re-contact each other, and the pusher plate 203 repeats the above action. The mechanism is connected to the left reinforcing component 300. Since the slot inside the air supply pipe 106 for air to enter the second bellows 109 is narrow, the airflow will not enter the air supply pipe 106 in time. Instead, it will push the sealing plate 209 to rise. At this time, the guide plate 208 re-engages with the second air supply box 201, and the left reinforcing plate 302 fixes the position of the mechanism. At this time, the bidirectional movement state of the device has been fully demonstrated.

[0049] When the two reinforcing components 300 come into contact, the two bellows 303 also abut and squeeze each other. The lubricating oil inside them flows through the groove inside the sliding tube 301 and finally contacts the outside of the ball 305. As the ball 305 rolls, it coats its entire body, which makes the device work more smoothly.
