Description

Technical Field

[0001] This invention relates to the field of linear guide technology, and in particular to a telescopic rolling linear guide with a locking device. Background Technology

[0002] Rolling linear guides are mainly composed of parts such as rails, sliders, limit stops, rolling elements, impact blocks, cages, sealing covers, and anti-collision blocks, and are widely used in the machinery industry.

[0003] In high-temperature environments, the main function of existing rolling linear guide pairs is to handle high loads and perform reciprocating linear motion. However, in certain high-temperature or high-speed applications, the components of conventional guide pairs can deform due to temperature changes, affecting the smoothness of the rolling elements in the circulation loop, thereby reducing the guide's response speed and accuracy.

[0004] To address this, invention publication CN106015328B discloses a rolling linear guide pair. The key technical features are as follows: it includes a linear guide, a slider, a return mechanism, and balls. Each end of the slider has a return mechanism. One surface of the slider is concave to form a first groove. The return mechanism forms a corresponding groove. A heat sink is provided on the inner wall of the first groove. Raceways are symmetrically arranged on the left and right side walls of the first groove. A circulation channel is formed between the raceways and the return mechanism. The balls are installed within the circulation channel. The linear guide movably engages with the balls, causing the slider to move linearly relative to the guide. A mounting opening is also formed on the slider, and a temperature sensor is installed within the mounting opening. This rolling linear guide pair exhibits excellent thermal stability.

[0005] Regarding the above-mentioned issues, the inventors believe that the following technical defects exist: In the prior art, the telescopic rolling linear guide cannot lock the slider when it moves to the limited position, which easily causes the slider to retract after moving to the limit position. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a telescopic rolling linear guide with a locking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic rolling linear guide with a locking device, comprising a base and an adjusting device, wherein a telescopic plate is installed on the inner wall of the base, a plurality of balls are installed inside the telescopic plate, a retainer is installed on the inner wall of the base, the adjusting device is located on the base, auxiliary devices are provided on both sides of the base with the aid of the adjusting device, and a lubrication device is provided on the telescopic plate with the aid of the adjusting device.

[0008] Using the above technical solution, when the telescopic linear guide is in use, the telescopic plate will move along the inner wall of the base with the help of the ball bearings. The telescopic linear guide has a simple structure, high load-bearing capacity, and strong durability.

[0009] Preferably, the adjusting device includes two limiting frames, which are fixedly connected to both sides of the base. The limiting frames have a U-shaped cross-section, and several limiting holes are evenly distributed on both sides of the inner wall of the limiting frames. A sliding hole is provided on the upper surface of the connecting frame. Two support plates are fixedly connected to the upper surface of the telescopic plate. The support plates have an L-shaped cross-section, and the side of the short arm end of the support plate is slidably connected to the inner wall of the sliding hole. An adjusting component for limiting the telescopic plate is provided on the lower surface of the short arm end of the support plate. The adjusting component includes a connecting column, the arc surface of which is fixedly connected to the support plate. The support plate has two fixed seats that are mirror-symmetrical. A rotating shaft is rotatably connected to the inner wall of each fixed seat. A connecting plate is fixedly connected to the arc surface of the rotating shaft. A limiting rod that connects to a limiting hole is fixedly connected to the upper surface of the short arm end of the connecting plate. The size of the limiting rod is slightly larger than the size of the limiting hole. A coil spring that drives the connecting plate to rotate toward the limiting hole is sleeved on the arc surface of the rotating shaft. The two ends of the coil spring are fixedly connected to the fixed seat and the connecting plate, respectively. An adjusting rod that limits the position of the support plate is slidably passed through the side of the short arm end of the support plate. The adjusting rod is fixedly connected to the inner wall of the sliding hole. An arc block that facilitates the insertion of the limiting rod into the limiting hole is fixedly connected to one end of the limiting rod.

[0010] By adopting the above technical solution and setting an adjustment device, the telescopic plate can be locked and fixed after being moved to a designated position, thereby improving the practicality and applicability of the telescopic linear guide and making it suitable for more application scenarios and environments.

[0011] Preferably, the arc surface of the connecting column is provided with a limiting component, the limiting component includes a circular hole, the circular hole is opened on the arc surface of the connecting column, a servo motor is fixedly connected to the bottom of the inner wall of the circular hole, a lead screw is fixedly connected to the output end of the servo motor, and a connecting frame that drives the two connecting plates to rotate in a direction closer to each other is threadedly connected to the arc surface of the lead screw, the cross section of the connecting frame is "U" shaped.

[0012] Using this preferred solution, when automatic control of the rotation of the connecting plate and the limiting rod is required, the servo motor is first started to drive the lead screw to rotate. The lead screw drives the connecting frame connected to it by threads, which in turn moves the "U"-shaped connecting frame closer to the connecting plate. Thus, the connecting frame can simultaneously drive the two connecting plates to move closer to each other. Activating the servo motor to drive the lead screw to rotate in the opposite direction separates the connecting frame from the connecting plate, allowing the connecting plates to move away from each other under the drive of the coil spring. This allows the connecting plate to automatically insert the limiting rod into the limiting hole. By setting the limiting component, the adjustment component can be controlled simply by starting the servo motor, eliminating the need for manual control. This improves the automation and ease of use of the telescopic rolling linear guide.

[0013] Preferably, both ends of the connecting frame are fixedly connected with pulleys to reduce the friction between the connecting frame and the connecting plate, and the arc surface of the pulley abuts against the connecting plate.

[0014] By adopting this preferred solution, the pulley can convert the sliding friction between the connecting frame and the connecting plate into rolling friction, thereby reducing the friction between the connecting frame and the connecting plate and improving the driving efficiency of the connecting frame on the connecting plate.

[0015] Preferably, a plurality of guide rods for limiting the position of the connecting frame are slidably provided on the side of the connecting frame, and one end of the guide rod is fixedly connected to the arc surface of the connecting column.

[0016] With this preferred solution, when the lead screw drives the connecting frame to move, the guide rod can limit the connecting frame, thus preventing rotational displacement during the movement of the connecting frame.

[0017] Preferably, the auxiliary device includes a side plate for covering the adjustment component and the limiting component. The side plate has a U-shaped cross-section. One side of the side plate abuts against the limiting frame. A partition is fixedly connected to the lower surface of the side plate. A welding plate is fixedly connected to the lower surface of the connecting frame. A positioning component is provided on the side of the welding plate. The positioning component includes a connecting post. The connecting post is slidably connected to the welding plate and to the partition. A connecting hole is opened on the arc surface of the connecting post. A screw is rotatably inserted through the surface of the connecting post. The rod is rotatably connected to one side of the inner wall of the connecting hole. Several auxiliary plates are fixedly connected to the inner wall of the connecting hole. A positioning rod is slidably inserted through the side of the auxiliary plate. One end of the positioning rod is fixedly connected to a positioning block that limits the position of the connecting column. The positioning block has a right-angled trapezoidal cross section. One side of the positioning block abuts against the welding plate. The arc surface of the screw is threadedly connected to a top block for driving the positioning block. The top block has an isosceles trapezoidal cross section. The top block abuts against the positioning block. The arc surface of the connecting column is threadedly connected to an adjusting ring that limits the position of the connecting column.

[0018] By adopting the above technical solution and by setting up auxiliary devices, personnel can easily connect the side plate to the limiting frame, thereby enabling the side plate to cover and protect the internal structure of the limiting frame, and improving the service life of the adjustment component and the limiting component.

[0019] Preferably, the arc surface of the positioning rod is fitted with a spring that drives the positioning block to move towards the top block, and the two ends of the spring are fixedly connected to the auxiliary plate and the positioning rod, respectively.

[0020] With this preferred solution, after the top block and the positioning block are separated, the spring can drive the two positioning blocks to move quickly toward each other, thereby achieving the effect of quickly retracting the positioning blocks into the connecting hole, thus achieving the effect of quickly disassembling the side plate.

[0021] Preferably, an anti-slip pad that increases the friction on one side of the adjusting ring is fixedly connected to the side of the adjusting ring near the connecting post, and one side of the anti-slip pad abuts against the connecting post.

[0022] By adopting this preferred solution, the anti-slip pad can increase the friction on one side of the adjusting ring, thereby enabling the adjusting ring to be firmly abutted against the partition with the help of the anti-slip pad.

[0023] Preferably, the lubrication device includes a connecting plate, one side of which is fixedly connected to the long arm end of a support plate. A syringe containing lubricating oil is fixedly connected to the surface of the connecting plate. One end of the syringe is fixedly connected to an injection head for injecting or drawing lubricating oil. A gear ring is rotatably connected to one end of the syringe. A drive rod is threadedly connected to the inner wall of the gear ring. A connecting block is fixedly connected to the arc surface of the syringe. A drive motor is fixedly connected to the upper surface of the connecting block. A gear for driving the gear ring to rotate is fixedly connected to the output end of the drive motor. The gear meshes with the gear ring. A piston for controlling the lubricating oil is fixedly connected to one end of the drive rod. The arc surface of the piston is in contact with the inner wall of the syringe.

[0024] By adopting the above technical solution, by setting up a lubrication device and starting the drive motor, the lubricating oil can be automatically attached to the guide rail, and the lubricating oil can lubricate the inner wall of the guide rail base, thereby improving the smoothness of the telescopic plate movement and achieving the effect of increasing the service life of the telescopic rolling linear guide rail.

[0025] Preferably, one end of the injection head is press-fitted with a rubber stopper that plugs the injection head, and the size of the rubber stopper is slightly larger than the size of the injection head.

[0026] By adopting this preferred solution, the movable rubber stopper blocks the injection head, which can prevent dust and other dirt from clogging the injection head and affecting its normal use.

[0027] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0028] 1. In this invention, the telescopic linear guide rail, when in use, the telescopic plate moves along the inner wall of the base with the help of ball bearings. This telescopic linear guide rail has a simple structure, high load-bearing capacity, and strong durability. When it is necessary to lock the telescopic plate after it has moved to a certain position, first press the two connecting plates with your hands and rotate them towards each other. The connecting plates drive the limiting rod. When the limiting rod separates from the limiting hole on the limiting frame, the position of the telescopic plate can be adjusted. During the movement of the telescopic plate, it will drive the support plate to move along the inner wall of the sliding hole on the limiting frame. Under the limitation of the adjusting rod, the support plate drives the adjusting component to move. When the telescopic plate stops at the appropriate position, the two connecting plates are released. At this time, the connecting plate will be inserted into the limiting hole under the drive of the coil spring. The telescopic plate can then be locked and limited by the adjusting component. By setting the adjusting device, the telescopic plate can be locked and fixed after it has moved to the designated position, thereby improving the practicality and applicability of the telescopic linear guide rail, making it suitable for more usage scenarios and environments.

[0029] 2. In this invention, when automatic control of the rotation of the connecting plate and the limiting rod is required, the servo motor is first started to drive the lead screw to rotate. The lead screw drives the connecting frame connected to it by a thread, which in turn moves the "U"-shaped connecting frame closer to the connecting plate. Thus, the connecting frame can simultaneously drive the two connecting plates to move closer to each other. Starting the servo motor to drive the lead screw to rotate in the opposite direction can separate the connecting frame from the connecting plate, allowing the connecting plates to move away from each other under the drive of the coil spring. This allows the connecting plate to automatically insert the limiting rod into the limiting hole. By setting the limiting component, the adjustment component can be controlled simply by starting the servo motor, eliminating the need for manual control. This improves the automation and ease of use of the telescopic rolling linear guide. The pulley can convert the sliding friction between the connecting frame and the connecting plate into rolling friction, thereby reducing the friction between the connecting frame and the connecting plate and improving the driving efficiency of the connecting frame on the connecting plate. In addition, when the lead screw drives the connecting frame to move, the guide rod can limit the connecting frame, achieving the effect of preventing rotational deviation during the movement of the connecting frame.

[0030] 3. In this invention, when it is necessary to install a side plate to protect the adjustment and limiting components inside the limiting frame, first move the side plate to fit against one side of the limiting frame, align the partition plate with the welding plate, and then use the positioning component to fix the side plate. Specifically, first move the connecting column to insert it into the partition plate and welding plate in sequence, then rotate the screw to drive the top block threaded to it. The top block simultaneously presses against the positioning blocks on its two inclined surfaces, causing the positioning blocks to extend from the connecting hole under the limitation of the positioning rod. After the positioning blocks extend from the connecting hole, move the positioning blocks to abut against one side of the welding plate, and then rotate the adjusting ring to abut against the partition plate, thus fixing the side plate. This allows the side plate to protect and cover the internal structure of the limiting frame. When it is necessary to inspect and maintain the internal structure of the limiting frame... By rotating the screw in the opposite direction, the top block separates from the two positioning blocks. Then, the two positioning blocks are moved into the connecting hole, allowing the connecting column to be pulled out from the partition and welding plate, thus removing the side plate. After the top block separates from the positioning blocks, the spring can drive the two positioning blocks to move quickly towards each other, thereby quickly retracting the positioning blocks into the connecting hole and achieving the effect of quick removal of the side plate. The anti-slip pad increases the friction on one side of the adjusting ring, enabling the adjusting ring to be firmly abutted against the partition with the help of the anti-slip pad. By setting up auxiliary devices, personnel can easily connect the side plate to the limiting frame, thereby enabling the side plate to cover and protect the internal structure of the limiting frame, improving the service life of the adjusting and limiting components.

[0031] 4. In this invention, when lubrication of the telescopic rolling linear guide is required, the telescopic plate is first started to move slowly along the inner wall of the base. At the same time, the drive motor is started to drive the gear to rotate. The gear drives the meshing gear ring to rotate. The rotation of the gear ring causes the drive rod on its inner wall to move vertically downward. The drive rod drives the piston to move downward, thereby causing the piston to drive the lubricating oil on the inner wall of the injection cylinder to come out from the injection head. This allows the lubricating oil to adhere to the contact part between the base and the telescopic plate, thus lubricating the guide. When the lubricating oil in the injection cylinder is used up, the injection head is first inserted into the container containing lubricating oil, and then the drive motor is started to drive the gear to rotate in the opposite direction. At this time, the piston will drive the lubricating oil into the injection cylinder, thus replenishing the lubricating oil. Moving the rubber stopper to block the injection head can prevent dust and other dirt from clogging the injection head and affecting its normal use. By setting up a lubrication device, starting the drive motor can make the lubricating oil automatically adhere to the guide rail, so that the lubricating oil lubricates the inner wall of the guide rail base, improving the smoothness of the telescopic plate's movement and achieving the effect of improving the service life of the telescopic rolling linear guide.

Detailed Implementation

[0045] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0046] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0047] Example 1, as Figure 1-12 As shown, the present invention provides a telescopic rolling linear guide with a locking device, including a base 1 and an adjusting device 3. A telescopic plate 2 is installed on the inner wall of the base 1, and a plurality of balls are installed inside the telescopic plate 2. A retainer 6 is installed on the inner wall of the base 1. The adjusting device 3 is located on the base 1. Auxiliary devices 4 are provided on both sides of the base 1 with the help of the adjusting device 3. A lubrication device 5 is provided on the telescopic plate 2 with the help of the adjusting device 3. When the telescopic linear guide is in use, the telescopic plate 2 will move telescopically along the inner wall of the base 1 with the help of the balls. The telescopic linear guide has a simple structure, high load-bearing capacity, and strong durability.

[0048] The specific settings and functions of its adjustment device 3, auxiliary device 4, and lubrication device 5 will be described in detail below.

[0049] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the adjusting device 3 includes two limiting frames 31, which are fixedly connected to both sides of the base 1. The cross-section of the limiting frame 31 is U-shaped. Several limiting holes 32 are opened on both sides of the inner wall of the limiting frame 31. The limiting holes 32 are evenly distributed on both sides of the inner wall of the limiting frame 31. A sliding hole 33 is opened on the upper surface of the connecting frame. Two support plates 34 are fixedly connected to the upper surface of the telescopic plate 2. The cross-section of the support plate 34 is L-shaped. The side of the short arm end of the support plate 34 is slidably connected to the inner wall of the sliding hole 33. The lower surface of the short arm end of the support plate 34 is provided with an adjusting component 35 for limiting the telescopic plate 2. The adjusting component 35 includes a connecting post 351. The arc surface of the connecting post 351 is fixedly connected to the support plate 34. Two fixed seats 352 are mirror-symmetrical. A rotating shaft 353 is rotatably connected to the inner wall of each fixed seat 352. A connecting plate 354 is fixedly connected to the arc surface of the rotating shaft 353. A limiting rod 356, which connects to a limiting hole 32, is fixedly connected to the upper surface of the short arm end of the connecting plate 354. The limiting rod 356 is slightly larger than the limiting hole 32. A coil spring 355, which drives the connecting plate 354 to rotate towards the limiting hole 32, is sleeved on the arc surface of the rotating shaft 353. Both ends of the coil spring 355 are fixedly connected to the fixed seat 352 and the connecting plate 354, respectively. An adjusting rod 38, which limits the movement of the support plate 34, slides through the side of the short arm end of the support plate 34. The adjusting rod 38 is fixedly connected to the inner wall of the sliding hole 33. One end of the limiting rod 356 is fixedly connected to a... When the limiting rod 356 is inserted into the arc block 37 inside the limiting hole 32, and when it is necessary for the telescopic plate 2 to be locked after moving to a certain position, first press the two connecting plates 354 with your hands to rotate them towards each other. The connecting plates 354 drive the limiting rod 356. When the limiting rod 356 separates from the limiting hole 32 on the limiting frame 31, the position of the telescopic plate 2 can be adjusted. During the movement of the telescopic plate 2, it will drive the support plate 34 to move along the inner wall of the sliding hole 33 on the limiting frame 31. Under the limitation of the adjusting rod 38, the support plate 34 drives the adjusting component 35 to move. When the telescopic plate 2 moves to the appropriate position and stops, release the two connecting plates 354. At this time, the connecting plates 354 will be inserted into the limiting hole 32 under the drive of the coil spring 355, and can be locked with the help of the... The adjusting component 35 locks and limits the telescopic plate 2. By setting the adjusting device 3, the telescopic plate 2 can be locked and fixed after being moved to a designated position, thereby improving the practicality and applicability of the telescopic linear guide, making it suitable for more application scenarios and environments. The arc surface of the connecting column 351 is provided with a limiting component 36, which includes a circular hole 361. The circular hole 361 is opened on the arc surface of the connecting column 351. A servo motor 362 is fixedly connected to the bottom of the inner wall of the circular hole 361. A lead screw 363 is fixedly connected to the output end of the servo motor 362. The arc surface of the lead screw 363 is threadedly connected to a connecting frame 364 that drives the two connecting plates 354 to rotate in a direction closer to each other. The cross-section of the connecting frame 364 is U-shaped.When automatic control of the rotation of the connecting plate 354 and the limiting rod 356 is required, the servo motor 362 is first started to drive the lead screw 363 to rotate. The lead screw 363 drives the connecting bracket 364, which is threadedly connected to it. This allows the "U"-shaped connecting bracket 364 to move closer to the connecting plate 354. The connecting bracket 364 can then simultaneously drive the two connecting plates 354 to move closer to each other. Activating the servo motor 362 to drive the lead screw 363 to rotate in the opposite direction separates the connecting bracket 364 from the connecting plate 354. This allows the connecting plates 354 to move further apart under the drive of the coil spring 355. This allows the connecting plate 354 to automatically insert the limiting rod 356 into the limiting hole 32. By setting the limiting component 36, the adjusting component 35 can be controlled simply by starting the servo motor 362, eliminating the need for manual control and improving the performance of this telescopic rolling linear guide. The automation of the rail improves the ease of use of the telescopic rolling linear guide. Both ends of the connecting frame 364 are fixedly connected to pulleys 366, which reduce the friction between the connecting frame 364 and the connecting plate 354. The arc surface of the pulleys 366 abuts against the connecting plate 354, converting the sliding friction between the connecting frame 364 and the connecting plate 354 into rolling friction, thereby reducing the friction between the connecting frame 364 and the connecting plate 354 and improving the driving efficiency of the connecting frame 364 on the connecting plate 354. Several guide rods 365 slide through the side of the connecting frame 364 to limit its movement. One end of each guide rod 365 is fixedly connected to the arc surface of the connecting post 351. When the lead screw 363 drives the connecting frame 364 to move, the guide rods 365 can limit the movement of the connecting frame 364, achieving the effect of preventing rotational deviation during the movement of the connecting frame 364.

[0050] The effect achieved by the entire adjustment device 3 is that, by setting the adjustment device 3, the telescopic plate 2 can be moved to a designated position and then locked and fixed, thereby improving the practicality and applicability of the telescopic linear guide rail, and making the telescopic linear guide rail applicable to more usage scenarios and environments.

[0051] like Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the auxiliary device 4 includes a side plate 41 for covering the adjustment component 35 and the limiting component 36. The side plate 41 has a U-shaped cross-section. One side of the side plate 41 abuts against the limiting frame 31. A partition plate 42 is fixedly connected to the lower surface of the side plate 41. A welding plate 43 is fixedly connected to the lower surface of the connecting frame. A positioning component 44 is provided on the side of the welding plate 43. The positioning component 44 includes a connecting post 441. The connecting post 441 is slidably connected to the welding plate 43 and to the partition plate 42. A connecting hole 442 is opened on the arc surface of the connecting post 441. A screw 443 is rotatably inserted through the surface of the connecting post 441. The screw 443 is rotatably connected to one side of the inner wall of the connecting hole 442. Several auxiliary components are fixedly connected to the inner wall of the connecting hole 442. A positioning rod 446 is slidably inserted through the side of the auxiliary plate 445. One end of the positioning rod 446 is fixedly connected to a positioning block 447 that limits the position of the connecting column 441. The positioning block 447 has a right-angled trapezoidal cross section. One side of the positioning block 447 abuts against the welding plate 43. The arc surface of the screw 443 is threadedly connected to a top block 444 for driving the positioning block 447. The top block 444 has an isosceles trapezoidal cross section and abuts against the positioning block 447. The arc surface of the connecting column 441 is threadedly connected to an adjusting ring 449 that limits the position of the connecting column 441. When it is necessary to install the side plate 41 to protect the adjusting component 35 and the limiting component 36 inside the limiting frame 31, first move the side plate 41 to fit against one side of the limiting frame 31, and then... After the plate 42 and the welding plate 43 are aligned, the side plate 41 is fixed with the help of the positioning component 44. The specific steps are as follows: first, the moving connecting column 441 is inserted into the partition plate 42 and the welding plate 43 in sequence. Then, the screw 443 is rotated to drive the top block 444 that is threaded to it. The top block 444 presses the positioning blocks 447 on its two inclined surfaces at the same time, so that the positioning blocks 447 protrude from the connecting hole 442 under the limit of the positioning rod 446. After the positioning blocks 447 protrude from the connecting hole 442, the positioning blocks 447 are moved to abut against one side of the welding plate 43. Then, the adjusting ring 449 is rotated to abut against the partition plate 42, thereby fixing the side plate 41. The side plate 41 protects and covers the internal structure of the limiting frame 31. When it is necessary to inspect and maintain the internal structure of the limiting frame 31, the side plate 41 is fixed. When the screw 443 is rotated in the opposite direction, the top block 444 is separated from the two positioning blocks 447. Then, the two positioning blocks 447 are moved into the connecting hole 442, and the connecting column 441 can be pulled out from the partition plate 42 and the welding plate 43. The side plate 41 can then be disassembled. By setting the auxiliary device 4, personnel can easily connect the side plate 41 to the limiting frame 31, thereby enabling the side plate 41 to cover and protect the internal structure of the limiting frame 31, which improves the service life of the adjusting component 35 and the limiting component 36. The arc surface of the positioning rod 446 is fitted with a spring 448 that drives the positioning block 447 to move towards the top block 444. The two ends of the spring 448 are fixedly connected to the auxiliary plate 445 and the positioning rod 446, respectively. After the top block 444 is separated from the positioning block 447...Spring 448 can drive two positioning blocks 447 to move quickly toward each other, thereby quickly retracting the positioning blocks 447 into the connecting hole 442, thus achieving the effect of quick disassembly of the side plate 41. An anti-slip pad 45 is fixedly connected to the side of the adjusting ring 449 near the connecting post 441 to increase the friction on one side of the adjusting ring 449. One side of the anti-slip pad 45 abuts against the connecting post 441. The anti-slip pad 45 increases the friction on one side of the adjusting ring 449, achieving the effect of allowing the adjusting ring 449 to be firmly abutted against the partition plate 42 with the help of the anti-slip pad 45.

[0052] The effect of the entire auxiliary device 4 is that personnel can easily connect the side plate 41 with the limiting frame 31, thereby enabling the side plate 41 to cover and protect the internal structure of the limiting frame 31, and improving the service life of the adjustment component 35 and the limiting component 36.

[0053] like Figure 11 and Figure 12As shown, the lubrication device 5 includes a connecting plate 501. One side of the connecting plate 501 is fixedly connected to the long arm end of the support plate 34. An injection cylinder 502 for storing lubricating oil is fixedly connected to the surface of the connecting plate 501. One end of the injection cylinder 502 is fixedly connected to an injection head 503 for injecting or drawing lubricating oil. A toothed ring 504 is rotatably connected to one end of the injection cylinder 502. A drive rod 505 is threadedly connected to the inner wall of the toothed ring 504. A connecting block 506 is fixedly connected to the arc surface of the injection cylinder 502. A drive motor 507 is fixedly connected to the upper surface of the connecting block 506. The output end of 07 is fixedly connected to a gear 508 that drives the gear ring 504 to rotate. The gear 508 meshes with the gear ring 504. One end of the drive rod 505 is fixedly connected to a piston 509 that controls the lubricating oil. The arc surface of the piston 509 is in contact with the inner wall of the injection cylinder 502. When it is necessary to lubricate the telescopic rolling linear guide, the telescopic plate 2 is first started to move slowly along the inner wall of the base 1. At the same time, the drive motor 507 is started to drive the gear 508 to rotate. The gear 508 drives the gear ring 504 that meshes with it to rotate. The rotation of the gear ring 504 causes the drive rod on its inner wall to rotate. 505 moves vertically downwards, driving rod 505 to move piston 509 downwards. This causes piston 509 to drive the lubricating oil on the inner wall of injection cylinder 502 out of injection head 503, allowing the lubricating oil to adhere to the contact area between base 1 and telescopic plate 2, thus lubricating the guide rail. When the lubricating oil in injection cylinder 502 is depleted, first insert injection head 503 into a container filled with lubricating oil, then start drive motor 507 to drive gear 508 to rotate in the opposite direction. At this time, piston 509 will drive lubricating oil into injection cylinder 502, thus replenishing the lubricating oil. By placing the lubrication device 5 and starting the drive motor 507, the lubricating oil can be automatically applied to the guide rail, lubricating the inner wall of the guide rail base 1, improving the smoothness of the movement of the telescopic plate 2, and achieving the effect of increasing the service life of the telescopic rolling linear guide rail. One end of the injection head 503 is interference-connected with a rubber plug 510 that blocks the injection head 503. The size of the rubber plug 510 is slightly larger than the size of the injection head 503. Moving the rubber plug 510 to block the injection head 503 can prevent dust and other dirt from clogging the injection head 503 and affecting its normal use.

[0054] The effect of the entire lubrication device 5 is that when the drive motor 507 is started, the lubricating oil can be automatically attached to the guide rail, so that the lubricating oil lubricates the inner wall of the guide rail base 1, which improves the smoothness of the movement of the telescopic plate 2 and achieves the effect of increasing the service life of the telescopic rolling linear guide rail.

[0055] The overall working principle is as follows: When in use, the telescopic plate 2 moves along the inner wall of the base 1 with the help of ball bearings. This telescopic linear guide has a simple structure, high load-bearing capacity, and strong durability. When it is necessary to lock the telescopic plate 2 after it has moved to a certain position, first press the two connecting plates 354 by hand and rotate them towards each other. The connecting plates 354 drive the limiting rod 356. When the limiting rod 356 separates from the limiting hole 32 on the limiting frame 31, the position of the telescopic plate 2 can be adjusted. During the movement of the telescopic plate 2, it will drive the support plate 34 along the limiting... The inner wall of the sliding hole 33 on the frame 31 moves, and the support plate 34 drives the adjustment component 35 to move under the limit of the adjustment rod 38. When the telescopic plate 2 moves to the appropriate position and stops, the two connecting plates 354 are released. At this time, the connecting plate 354 will be inserted into the limiting hole 32 under the drive of the coil spring 355. The telescopic plate 2 can be locked and limited by the adjustment component 35. By setting the adjustment device 3, the telescopic plate 2 can be locked and fixed after moving to the designated position, thereby improving the practicality and application range of the telescopic linear guide, and making the telescopic linear guide suitable for more application scenarios and environments.

[0056] When automatic control of the rotation of the connecting plate 354 and the limiting rod 356 is required, the servo motor 362 is first started to drive the lead screw 363 to rotate. The lead screw 363 drives the connecting bracket 364, which is threadedly connected to it. This allows the "U"-shaped connecting bracket 364 to move closer to the connecting plate 354. Thus, the connecting bracket 364 can simultaneously drive the two connecting plates 354 to move closer to each other. Activating the servo motor 362 to drive the lead screw 363 to rotate in the opposite direction can separate the connecting bracket 364 from the connecting plate 354. This allows the connecting plates 354 to move away from each other under the drive of the coil spring 355. This allows the connecting plate 354 to automatically insert the limiting rod 356 into the limiting hole 32. By setting the limit component 36, the adjustment component 35 can be controlled simply by starting the servo motor 362, eliminating the need for manual control. This improves the automation and ease of use of the telescopic rolling linear guide. The pulley 366 converts the sliding friction between the connecting frame 364 and the connecting plate 354 into rolling friction, thereby reducing the friction between them and improving the driving efficiency of the connecting frame 364 on the connecting plate 354. In addition, when the lead screw 363 drives the connecting frame 364 to move, the guide rod 365 can limit the movement of the connecting frame 364, preventing rotational deviation during its movement.

[0057] When it is necessary to install the side plate 41 to protect the adjustment component 35 and the limiting component 36 inside the limiting frame 31, first move the side plate 41 to fit against one side of the limiting frame 31, align the partition plate 42 with the welding plate 43, and then use the positioning component 44 to fix the side plate 41. The specific steps are as follows: first, move the connecting post 441 to insert it into the partition plate 42 and the welding plate 43 in sequence, then rotate the screw 443 to drive the top block 444 that is threadedly connected to it, and the top block 444 simultaneously presses against it. The positioning blocks 447 on both inclined surfaces extend from the connecting holes 442 under the limitation of the positioning rods 446. After the positioning blocks 447 extend from the connecting holes 442, they are moved to abut against one side of the welding plate 43. Then, the adjusting ring 449 is rotated to abut against the partition plate 42, thus fixing the side plate 41. This allows the side plate 41 to protect and cover the internal structure of the limiting frame 31. When it is necessary to inspect and maintain the internal structure of the limiting frame 31, the side plate 41 can be used to protect and cover the internal structure of the limiting frame 31. Rotating screw 443 separates top block 444 from two positioning blocks 447. Moving the two positioning blocks 447 into connecting hole 442 allows connecting column 441 to be pulled out from partition plate 42 and welding plate 43, thus disassembling side plate 41. After top block 444 separates from positioning blocks 447, spring 448 drives the two positioning blocks 447 to move quickly toward each other, thereby quickly retracting positioning blocks 447 into connecting hole 442 and achieving quick disassembly of side plate 41. Anti-slip pad 45 increases friction on one side of adjusting ring 449, allowing adjusting ring 449 to abut against partition plate 42 with the help of anti-slip pad 45. By setting auxiliary device 4, personnel can easily connect side plate 41 to limit frame 31, thereby allowing side plate 41 to cover and protect the internal structure of limit frame 31, improving the service life of adjusting component 35 and limit component 36.

[0058] When lubrication of the telescopic rolling linear guide is required, first, start the telescopic plate 2 to move slowly along the inner wall of the base 1. Simultaneously, start the drive motor 507 to drive the gear 508 to rotate. The gear 508 drives the meshing gear ring 504 to rotate. The rotation of the gear ring 504 causes the drive rod 505 on its inner wall to move vertically downwards. The drive rod 505 drives the piston 509 to move downwards, which in turn causes the piston 509 to drive the lubricating oil on the inner wall of the injection cylinder 502 to come out from the injection head 503. This allows the lubricating oil to adhere to the contact area between the base 1 and the telescopic plate 2, thus lubricating the guide. When the lubricating oil in the injection cylinder 502 is used up, first... Insert the injection head 503 into the container filled with lubricating oil, then start the drive motor 507 to drive the gear 508 to rotate in the opposite direction. At this time, the piston 509 will drive the lubricating oil into the injection cylinder 502, which can replenish the lubricating oil. Move the rubber stopper 510 to block the injection head 503, which can prevent dust and other dirt from clogging the injection head 503 and affecting its normal use. By setting the lubrication device 5, starting the drive motor 507 can make the lubricating oil automatically adhere to the guide rail, so that the lubricating oil lubricates the inner wall of the guide rail base 1, improving the smoothness of the movement of the telescopic plate 2, and achieving the effect of improving the service life of the telescopic rolling linear guide rail.
