Description

Technical Field

[0001] This invention mainly relates to the field of linear transmission component assembly technology, specifically a guide rail slider assembly fixture. Background Technology

[0002] Linear guides, as a high-precision, high-speed linear transmission component, are widely used in CNC machine tools, industrial robots, lithium battery equipment, and semiconductor manufacturing equipment. During the assembly of the guide slider, especially when installing the slider onto a long guide rail (real rail) that is already fixed on the machine bed, the balls or rollers inside the slider are in an unconstrained state and are very likely to fall off the slider, resulting in the slider being scrapped or assembly failure. To solve this problem, the industry usually uses "dummy rails" (also known as substitute rails or process strips) as an auxiliary tool. A dummy rail is a profile that simulates the shape of the rail raceway. During assembly, the dummy rail must first be inserted into the slider to support the rolling elements inside the slider. Then, the slider and the dummy rail are aligned together onto the real rail. The slider is then pushed into the real rail, and finally the dummy rail is removed.

[0003] However, most existing dummy rails are one-piece rigid structures, and their mating ends are usually only simple flat or chamfered designs, lacking pre-processing functions for the ends of the real rails. In actual production environments, after the real rails are installed, their ends often have metal shavings, polishing paste, or dust left over from the assembly process. When the slider is pushed in directly, these impurities are easily carried into the gap between the slider and the raceway of the real rail, causing scratches on the raceway, reduced accuracy, or even jamming failures, seriously affecting the service life and positioning accuracy of the equipment. Secondly, at the moment when the slider transitions from the dummy rail to the real rail, due to the tiny end face gap between the dummy rail and the real rail, the balls or rollers will experience a brief "suspended" or "falling" process, resulting in increased impact force, which not only affects the assembly feel but may also cause hidden damage to the rolling elements. In addition, existing dummy rails lack an effective timing control mechanism during assembly. Operators usually need to support the dummy rail with one hand to prevent it from slipping off, and push the slider with the other hand. The operation is cumbersome and it is difficult to guarantee the docking accuracy. Especially in the case of inverted or side-mounted installation, the slider on the dummy rail is prone to axial movement or falling off due to its own weight, which poses a safety hazard. Summary of the Invention

[0004] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. It mainly offers a guide rail slider assembly fixture to solve the technical problems mentioned in the background section, such as the lack of pre-processing functions, large impact during docking, and cumbersome operation of existing dummy rails.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A guide rail slider assembly fixture includes a dummy rail and also includes: A guide module is detachably connected to the docking end of the dummy track. The working surface of the guide module matches the outline of the real track. The guide module integrates a scraper for cleaning the real track and a wiper for lubricating the real track. The magnetic control linkage mechanism is located inside the dummy track. The magnetic control linkage mechanism includes an adsorption block and an elastic element. The adsorption block is slidably installed inside the dummy track and has an adsorption part for adsorbing the end face of the real track. The elastic element is connected between the adsorption block and the dummy track to provide a restoring force. The magnetic control linkage mechanism is set to be triggered by magnetic force when the dummy track docks with the real track to automatically control the state switching of the limit component. The outer periphery of the adsorption section is provided with an annular compressed air chamber. The docking end face of the dummy track facing the real track is provided with multiple exhaust holes that communicate with the annular compressed air chamber. When the adsorption block moves toward the real track, the volume of the annular compressed air chamber decreases and exhausts air to the end face of the real track through the exhaust holes. When the adsorption block is reset, outside air enters the annular compressed air chamber through the exhaust holes. A limiting component is disposed inside the dummy track. The limiting component includes a stop block and a limiting block. The stop block is disposed at the top of the dummy track, and the limiting block is slidably disposed on the side wall of the dummy track. When the adsorption block moves, it drives the limiting block to switch between blocking the extended position of the slider and releasing the retracted position of the slider. The limiting component is configured to release the slider for transition when the magnetic control linkage mechanism is triggered, and lock the slider to prevent it from falling off when the magnetic control linkage mechanism is reset.

[0006] More preferably, the guiding module includes a first guide block and a second guide block, wherein the first guide block is rotatably connected to the bottom of the dummy track via a first connecting rod, and the second guide block is rotatably connected to the bottom of the dummy track via a second connecting rod; The top of the first guide block is provided with a slot, and the top of the second guide block is provided with an insert. When the first connecting rod and the second connecting rod are rotated to be parallel to the dummy track, the insert is inserted into the slot and locked by the fastener. The first guide block and the second guide block are configured to form a complete contour channel after assembly for guiding the device.

[0007] More preferably, both the first guide block and the second guide block include a mounting portion and a guiding portion. The guiding portion conforms to the outer contour of the true track. The mounting portion has a receiving cavity, and the scraper and wiping component are detachably mounted in the receiving cavity. The scraper is used to remove assembly impurities from the surface of the actual track, and the wiper is used to wet and release lubricating oil to lubricate the starting section of the actual track.

[0008] More preferably, a pusher is provided on the top of the adsorption block, and a first wedge-shaped inclined surface is provided on the top of the pusher. The bottom of the limiting block is provided with a second wedge-shaped inclined surface that matches the first wedge-shaped inclined surface; When the adsorption block moves toward the direction closer to the true track, the first wedge-shaped inclined surface of the push block separates from the second wedge-shaped inclined surface of the limiting block, and the limiting block moves down to the retracted position; When the adsorption block is reset, the first wedge-shaped inclined surface of the push block contacts the second wedge-shaped inclined surface of the limiting block, and the push block drives the limiting block to move upward to the extended position.

[0009] More preferably, the scraper is made of polyoxymethylene or copper-based powder metallurgy material, and its inner edge is interference-fitted with the surface of the true track to enhance the scraping effect; The wiping component is made of porous polyurethane foam, which is impregnated with lubricating oil to achieve controlled release of a small amount of oil. The scraper and wiping components are arranged sequentially along the sliding block's travel direction for cleaning followed by lubrication.

[0010] More preferably, the bottom of the dummy track is provided with a groove corresponding to the position of the first connecting rod and the second connecting rod, and the ends of the first connecting rod and the second connecting rod are rotatably disposed in the groove so that the bottom surface of the dummy track remains flat.

[0011] More preferably, the side wall of the dummy track is provided with a sliding groove, the limiting block is slidably installed in the sliding groove, the two sides of the sliding groove are provided with movable grooves, the two sides of the limiting block are provided with sliding blocks, and the sliding blocks are limited in the movable grooves to prevent the limiting block from disengaging from the sliding groove. The limiting block is used to cooperate with the stop block to form a closed fence when in the extended position, so as to axially constrain the slider; The side wall of the dummy track is provided with a moving groove, and the adsorption block is slidably disposed in the moving groove. The side wall of the dummy track is detachably equipped with a cover plate, which is used to close the moving groove, the movable groove and the sliding groove.

[0012] In a further preferred embodiment, a spring is provided in the movable groove, with the two ends of the spring connected to the sliding block and the inner wall of the movable groove, respectively. The spring is used to output a downward elastic force. When the push block and the limiting block are separated, the limiting block is driven to move down by the spring force to achieve reset.

[0013] More preferably, the adsorption block includes a sliding part and an adsorption part. The adsorption part is made of a magnetic component and protrudes from the sliding part. The cover plate has a through hole for the adsorption part to pass through, and the diameter of the through hole is smaller than the diameter of the sliding part. The cover plate is used to prevent the adsorption block from falling out. The outer peripheral surface of the sliding part is in a sealed sliding fit with the inner wall of the moving groove, and the outer peripheral surface of the adsorption part is in a sealed sliding fit with the inner wall of the through hole on the cover plate, so that the volume of the annular compressed air chamber changes with the axial movement of the adsorption block.

[0014] More preferably, the outer periphery of the adsorption section is provided with an annular compressed air chamber, and the docking end face of the dummy track facing the real track is provided with multiple exhaust holes communicating with the annular compressed air chamber. When the adsorption block moves toward the real track, the volume of the annular compressed air chamber decreases and exhausts air to the end face of the real track through the exhaust holes. When the adsorption block is reset, outside air enters through the exhaust holes. There are four exhaust holes, which are respectively located near the four corners of the docking end face. The air inlet end of each exhaust hole is connected to the annular compressed air chamber, and the air outlet end faces the end face of the real track. The central axis of each exhaust hole is inclined outward relative to the length direction of the dummy track. The projection of the central axis on the docking end face points from the center of the docking end face to the corresponding outer edge annular compressed air chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a first guide block and a second guide block to assemble a contoured channel that matches the outer contour of the real track. When the dummy track and the real track are connected, the dummy track guides them, reducing lateral offset, height deviation and angle deviation. At the same time, the scraper and wiper sequentially clean impurities and provide a small amount of lubrication to the starting section of the real track. This provides an assembly path that is accurate in position, clean on the surface and fully lubricated for the slider to smoothly transition from the dummy track to the real track, reducing the possibility of impurities entering the raceway and slider assembly jamming.

[0016] 2. This invention uses the magnetic attraction force generated by the real track on the adsorption block to drive the adsorption block and push block to move, so that the first wedge-shaped inclined surface of the push block separates from the second wedge-shaped inclined surface of the limiting block, and the limiting block is automatically moved down to the retracted position by the spring. Thus, after the dummy track and the real track have completed the guiding docking, cleaning and lubrication, the restriction on the slider is automatically released, forming a linkage relationship of releasing the slider after docking is completed. At the same time, it can maintain the end face docking state of the dummy track and the real track, reducing the impact generated when the rolling element passes through the docking position. Furthermore, the magnetic drive block compresses the annular air chamber, causing the four corner exhaust holes to blow outwards to remove debris from the end face and the inlet of the raceway. At the same time, the linkage limit block retracts, achieving automatic release after cleaning.

[0017] 3. This invention uses an elastic element to drive the adsorption block and push block to reset after the dummy track separates from the real track. The push block, through the cooperation of the first and second wedge-shaped inclined surfaces, lifts the limiting block back to the extended position, and the limiting block and the stop block cooperate to axially limit the slider. The elastic element drives the adsorption block to reset, allowing outside air to replenish the annular air chamber and relock the limiting block and the stop block. This forms a continuous linkage process of contour guiding and cleaning lubrication - magnetic attraction docking and automatic release - docking purging - separation reset and automatic locking, preventing the slider from accidentally moving or falling off along the dummy track during inverted installation, side installation, transportation or maintenance.

[0021] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the present invention. However, the present invention can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of the present invention more thorough and complete.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0023] Please refer to the appendix carefully. Figures 1-5 A guide rail slider assembly fixture includes a dummy track 1, a guide module, a magnetic control linkage mechanism, and a limit component; The dummy track 1 is long and narrow, and its cross-sectional profile is adapted to the distribution position of the balls inside the slider to be assembled, so that the slider can be fitted onto the outside of the dummy track 1 and can move along the length of the dummy track 1. The dummy track 1 can be made of engineering plastics such as polyoxymethylene and reinforced nylon, which have certain structural strength and are not easy to damage the balls.

[0024] One end of the dummy track 1 is a docking end for contacting the end face of the real track. The guide module is detachably connected to the docking end of the dummy track 1. The working surface of the guide module matches the outline of the real track and is used to guide the dummy track 1 to correspond to the real track when it approaches the real track. The guide module integrates a scraper 6 and a wiping component 7, which are used to clean and lubricate the starting section of the real track in sequence before the slider enters the real track. The magnetic control linkage mechanism is installed near the docking end of the dummy track 1 and is connected to the limit component for transmission. The limit component restricts the slider from moving along the axial direction of the dummy track 1. After the dummy track 1 docks with the real track, the magnetic control linkage mechanism is activated by the magnetic attraction of the real track and drives the limit component to release the restriction on the slider, so that the slider can be transferred from the dummy track 1 to the real track.

[0025] The dummy track 1 has a moving groove and a cover plate 9 that closes the moving groove near the docking end. The adsorption block 11 includes a sliding part that is slidably disposed in the moving groove and an adsorption part that passes through the cover plate 9. The end face of the sliding part facing the cover plate 9, the inner wall of the moving groove, and the inner side of the cover plate 9 together form an annular compressed air chamber surrounding the adsorption part. The docking end face of the dummy track 1 facing the real track has multiple exhaust holes 14 that communicate with the annular compressed air chamber. When the adsorption block 11 moves toward the real track, the volume of the annular compressed air chamber decreases and exhausts air to the end face of the real track through the exhaust holes 14. When the adsorption block 11 is reset, outside air enters the annular compressed air chamber through the exhaust holes 14.

[0026] The magnetic linkage mechanism includes an adsorption block 11 and an elastic element 12. The adsorption block 11 is slidably installed in the dummy track 1. The adsorption block 11 has an adsorption part for adsorbing the end face of the real track. The elastic element 12 is connected between the adsorption block 11 and the dummy track 1 to provide a restoring force. The magnetic linkage mechanism is set to be triggered by magnetic force when the dummy track 1 docks with the real track to automatically control the state switching of the limit component. The limiting component includes a stop block 8 and a limiting block 10. The stop block 8 is located on the top of the dummy track 1, and the limiting block 10 is slidably located on the side wall of the dummy track 1. When the adsorption block 11 moves, it drives the limiting block 10 to switch between the extended position of blocking the slider and the retracted position of releasing the slider. The limiting component is configured to release the slider for transition when the magnetic control linkage mechanism is triggered, and lock the slider to prevent it from falling off when the magnetic control linkage mechanism is reset.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the guide module includes a first connecting rod 2, a second connecting rod 3, a first guide block 4, and a second guide block 5.

[0028] A groove is provided at the bottom of the dummy track 1 near the docking end. One end of the first connecting rod 2 and the second connecting rod 3 are respectively rotatably installed in the groove via a rotating shaft. The rotating shaft can be a pin, and its end is axially limited by a snap ring, nut or limit pin, so that the first connecting rod 2 and the second connecting rod 3 can rotate relative to the dummy track 1. After removing the corresponding axial limiting parts, the first connecting rod 2 and the second connecting rod 3 can be removed from the dummy track 1, thereby realizing the overall replacement of the guide module.

[0029] The first connecting rod 2 and the second connecting rod 3 can be made of non-magnetic materials with certain structural strength, such as polyoxymethylene or reinforced nylon. In this embodiment, both the first connecting rod 2 and the second connecting rod 3 are L-shaped. The end of the first connecting rod 2 away from the dummy track 1 is connected to the first guide block 4, and the end of the second connecting rod 3 away from the dummy track 1 is connected to the second guide block 5.

[0030] The rotating ends of the first connecting rod 2 and the second connecting rod 3 are accommodated in the groove at the bottom of the dummy track 1, and the depth of the groove is matched with the thickness of the rotating end of the connecting rod, so that the rotating end of the connecting rod does not protrude from the bottom surface of the dummy track 1, thereby keeping the bottom surface of the dummy track 1 flat and preventing the connecting rod from affecting the placement and positioning of the dummy track 1.

[0031] The first guide block 4 and the second guide block 5 are located on both sides of the docking end of the dummy track 1, respectively. During assembly, the first connecting rod 2 and the second connecting rod 3 are rotated, and the first connecting rod 2 and the second connecting rod 3 respectively contact the outer walls on both sides of the dummy track 1, so that the two are parallel to the length direction of the dummy track 1. At this time, the first guide block 4 and the second guide block 5 approach each other.

[0032] The top of the first guide block 4 is provided with a slot 401, and the top of the second guide block 5 is provided with a plug 501 that is compatible with the slot 401. The slot 401 and the plug 501 are respectively provided with corresponding insertion holes. When the first guide block 4 and the second guide block 5 are assembled together, the plug 501 is inserted into the slot 401, and then the fixing pin, bolt and other fixing parts are passed through the corresponding insertion holes, thereby restricting the separation of the first guide block 4 and the second guide block 5.

[0033] After the first guide block 4 and the second guide block 5 are assembled, they together form a complete contouring channel. The center line of the contouring channel is consistent with the length direction of the dummy track 1, and its inner wall contour matches the outer contour of the real track. After the end of the real track enters the contouring channel, the first guide block 4 and the second guide block 5 guide it from both sides of the real track, thereby reducing the lateral deviation, height deviation and angle deviation between the dummy track 1 and the real track.

[0034] The first guide block 4 and the second guide block 5 can be made of polyoxymethylene or reinforced nylon material. The edges of the guide parts opposite to the real track can be rounded or have beveled edges so that the end of the real track can enter the contour channel and reduce the collision and scratches of the guide blocks on the surface of the real track.

[0035] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both the first guide block 4 and the second guide block 5 include a mounting portion and a guide portion. The guide portion is used to jointly form a contoured channel. The mounting portion is located outside the guide portion and its thickness is greater than that of the guide portion to provide the space required for mounting the scraper 6 and the wiping component 7.

[0036] The first guide block 4 and the second guide block 5 each have corresponding receiving cavities in their mounting sections. After the two guide blocks are assembled, the corresponding receiving cavities together form an installation space for installing the scraper 6 and the wiping component 7.

[0037] The scraper 6 can be composed of two scraping parts, which are respectively installed in the receiving cavities of the first guide block 4 and the second guide block 5. After the first guide block 4 and the second guide block 5 are assembled, the two scraping parts together form a scraping opening that matches the outer contour of the true track.

[0038] The scraper 6 can be made of polyoxymethylene material. The wear resistance and relatively low coefficient of friction of polyoxymethylene material reduce the possibility of the scraper 6 scratching the real track. The inner edge of the scraper 6 forms a slight interference fit with the surface of the real track, so that when the real track and the scraper 6 move relative to each other, the scraper 6 can scrape off dust, packaging debris and other assembly impurities from the surface of the real track. The interference fit is such that the scraper 6 can contact the surface of the real track without affecting the normal entry of the real track.

[0039] The wiping component 7 is also composed of two wiping parts, which are respectively installed in the receiving cavities of the first guide block 4 and the second guide block 5. After the two guide blocks are assembled, the two wiping parts together form a wiping opening that matches the outer contour of the true track.

[0040] The wiping component 7 is made of porous polyurethane foam with interconnected pores. It is pre-impregnated with lubricating oil that is compatible with the guide rail slider. The wiping component 7 is in elastic contact with the surface of the real track. When it is squeezed by the real track, it can release a small amount of lubricating oil to the surface of the real track. After the squeezing pressure is released, its porous structure can continue to retain the remaining lubricating oil, thereby achieving micro-oil release.

[0041] The scraper 6 and the wiper 7 are arranged sequentially along the direction in which the slider moves from the dummy track 1 to the real track, so that the corresponding surface of the real track is first cleaned by the scraper 6 and then comes into contact with the wiper 7 and is lubricated, thus preventing the wiper 7 from directly carrying impurities from the surface of the real track into the slider.

[0042] The scraper 6 and the wiping component 7 can be detachably installed in the receiving cavity via a slot, pressure plate or screw. After the first guide block 4 and the second guide block 5 are separated, the corresponding scraper and wiping components can be taken out respectively for cleaning, replacement or adding lubricating oil to the wiping component 7.

[0043] After each use, the wear condition of the inner edge of the scraper 6 should be checked, and the lubricant content of the wiping part 7 should be checked regularly.

[0044] In this embodiment, as Figure 3 and Figure 5 As shown, the magnetic control linkage mechanism includes an adsorption block 11, an elastic element 12, and a push block 13.

[0045] The dummy track 1 has a moving groove on its side wall near the docking end. The moving groove extends along the length of the dummy track 1. The adsorption block 11 is slidably installed in the moving groove and can move between the trigger position near the real track and the reset position away from the real track.

[0046] The adsorption block 11 includes a sliding part and an adsorption part. The sliding part is cylindrical and slides with the moving groove. The adsorption part is fixedly set at the end of the sliding part near the real track. The adsorption part is made of a permanent magnet, and its diameter is smaller than that of the sliding part. The adsorption part is made of neodymium iron boron permanent magnet, and its end face shape is adapted to the end face shape of the real track. When the dummy track 1 is connected to the real track, the adsorption part can contact the end face of the real track or maintain a working air gap of no more than 0.5mm. At the same time, the sliding part contacts the cover plate 9. When the sliding part moves toward the cover plate 9 to the trigger position, it still retains a stop end clearance with the inner side of the cover plate 9 to avoid rigid collision and retain the minimum margin of the annular compressed air chamber.

[0047] In one possible implementation, the adsorption part can be an electromagnet, and the adsorption function can be achieved by controlling the on and off of the electromagnet through an external power supply. This is mainly suitable when the true track is made of weakly magnetic materials such as austenitic stainless steel.

[0048] It should be noted that this fixture is only suitable for assembling sliders on magnetic tracks.

[0049] In this embodiment, as Figure 3 and Figure 5 As shown, the elastic element 12 is disposed in the moving groove and connected between the adsorption block 11 and the dummy track 1. In this embodiment, the elastic element 12 is a tension spring, one end of which is connected to the sliding part of the adsorption block 11 and the other end is connected to the inner wall of the moving groove. When the adsorption block 11 is magnetically attracted by the real track and moves towards the real track, the elastic element 12 is stretched. When the adsorption block 11 is separated from the real track, the elastic element 12 drives the adsorption block 11 to return to the reset position through its own elastic force.

[0050] The elastic element 12 can be a compression spring, which can provide a force to the adsorption block 11 toward the reset position after the adsorption part is disengaged from the true track.

[0051] A push block 13 is fixedly connected to the top of the adsorption block 11. The push block 13 can move along the front and back direction inside the false track 1 with the adsorption block 11. A first wedge-shaped inclined surface is provided on the top of the push block 13. The height of the first wedge-shaped inclined surface gradually changes along the moving direction of the adsorption block 11.

[0052] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the limiting component includes a stop block 8 and a limiting block 10.

[0053] The stop block 8 is fixedly installed on the top of the dummy track 1 and located on the side of the slider away from the docking end of the dummy track 1. The stop block 8 can be integrally formed with the dummy track 1, or it can be detachably fixed to the dummy track 1 by screws or the like.

[0054] The side wall of the dummy track 1 near the docking end is provided with a groove extending in the vertical direction. The limiting block 10 is slidably installed in the groove and can move between the extended position and the retracted position. When the limiting block 10 is in the extended position, its upper end protrudes out of the slider movement profile of the dummy track 1 and cooperates with the stop block 8 to form a closed limiting area on both sides of the slider axis, thereby constraining the slider to move along the axis of the dummy track 1. When the limiting block 10 is in the retracted position, its upper end retracts into the dummy track 1 or exits the slider movement path, so that the slider can pass through the docking end of the dummy track 1.

[0055] The bottom of the limiting block 10 is provided with a second wedge-shaped inclined surface that matches the first wedge-shaped inclined surface on the push block 13. When the adsorption block 11 is in the reset position, the push block 13 is located below the limiting block 10. The first wedge-shaped inclined surface abuts against the second wedge-shaped inclined surface. The push block 13 pushes the limiting block 10 upward through the inclined surface cooperation, so that the limiting block 10 is kept in the extended position.

[0056] When the dummy track 1 aligns with the real track, the adsorption block 11 is subjected to magnetic force and moves toward the real track. The push block 13 moves synchronously with the adsorption block 11, causing the first wedge-shaped inclined surface to gradually separate from the second wedge-shaped inclined surface. After losing the upward support of the push block 13, the limiting block 10 moves down to the retracted position, thereby releasing the restriction on the slider.

[0057] When the dummy track 1 separates from the real track, the elastic element 12 drives the adsorption block 11 and the push block 13 to reset, and the first wedge-shaped inclined surface re-contacts the second wedge-shaped inclined surface. As the push block 13 continues to move, the first wedge-shaped inclined surface pushes the limiting block 10 upward, causing the limiting block 10 to move back to the extended position.

[0058] In this embodiment, as Figure 3 and Figure 5As shown, movable grooves are provided on both sides of the slide groove, and sliding blocks are fixedly provided on both sides of the limiting block 10. The sliding blocks are slidably installed in the corresponding movable grooves and can move up and down with the limiting block 10. The movable grooves guide and limit the sliding blocks to prevent the limiting block 10 from tilting during the up and down movement, and at the same time prevent the limiting block 10 from falling out of the slide groove.

[0059] Each movable slot is equipped with a spring. One end of the spring is connected to the sliding block, and the other end is connected to the upper inner wall of the movable slot. The spring outputs a downward elastic force to the sliding block. The springs in the two movable slots are symmetrically arranged so that the force on both sides of the limit block 10 is relatively uniform.

[0060] When the push block 13 separates from the limit block 10, the limit block 10 moves downward to the retracted position under the combined action of the two springs. Thus, the retraction action of the limit block 10 does not depend on its own gravity. Even if the dummy track 1 is in an inclined state or there is a certain frictional resistance between the limit block 10 and the slide, it can reliably exit the sliding path of the slider.

[0061] When the push block 13 resets and pushes the limit block 10 upward, the sliding block moves upward with the limit block 10 and compresses or stretches the corresponding spring, so that the spring stores the elastic potential energy that drives the limit block 10 to reset downward.

[0062] In this embodiment, as Figure 3 and Figure 5 As shown, a cover plate 9 is detachably installed on one side of the dummy track 1, which has a moving groove, a sliding groove and a movable groove. The cover plate 9 can be made of an engineering plastic plate with a certain structural strength and is fixed to the side wall of the dummy track 1 with screws.

[0063] The cover plate 9 is used to close the moving groove, sliding groove and movable groove to prevent the adsorption block 11, push block 13, limit block 10, sliding block and spring from coming out of the corresponding groove. After removing the cover plate 9, the magnetic control linkage mechanism and limit components can be installed, cleaned, lubricated and maintained.

[0064] Positioning posts and positioning holes can be provided between the cover plate 9 and the dummy track 1 to ensure that the position of the cover plate 9 is consistent when it is repeatedly installed. A clearance cavity for the push block 13 to move can be provided on the side of the cover plate 9 facing the dummy track 1 to avoid the cover plate 9 from hindering the reciprocating movement of the adsorption block 11 and the push block 13.

[0065] In this embodiment, as Figure 3 and Figure 5As shown, the cover plate 9 has a through hole corresponding to the position of the adsorption block 11, through which the adsorption part passes. The diameter of the through hole is adapted to the outer diameter of the adsorption part and smaller than the diameter of the sliding part, so that the cover plate 9 can restrict the sliding part from disengaging from the moving groove. A fluororubber sealing ring or an elastic sealing lip can be installed on the inner wall of the through hole to form a sealing sliding fit with the outer peripheral surface of the adsorption part; a fluororubber sealing ring can be correspondingly provided on the outer peripheral surface of the sliding part to form a sealing sliding fit with the inner wall of the moving groove. A small amount of lubricating grease compatible with the sealing material is applied to the sealing area to reduce reciprocating resistance.

[0066] When the adsorption block 11 is in the reset position, the sliding part and the cover plate 9 retain an axial travel for the adsorption block 11 to move toward the true track; the distance by which the adsorption part protrudes from the outer surface of the cover plate 9 can be set to 0.5-1.5mm so that an effective magnetic attraction is formed when the dummy track 1 approaches the end face of the true track. When the adsorption block 11 reaches the trigger position, a stop clearance of 0.2-0.8mm is preferably retained between the sliding part and the inner side of the cover plate 9.

[0067] The end face of the sliding part facing the cover plate 9, the inner wall of the moving groove, and the inner side of the cover plate 9 together form an annular compressed air chamber. The annular compressed air chamber is located on the outer periphery of the adsorption part and on the side of the sliding part closer to the true track. Since the outer peripheral surface of the sliding part is in a sealed sliding fit with the inner wall of the moving groove, and the outer peripheral surface of the adsorption part is in a sealed sliding fit with the inner wall of the through hole of the cover plate 9, when the adsorption block 11 moves towards the cover plate 9 and the true track, the axial length and volume of the annular compressed air chamber decrease simultaneously; when the adsorption block 11 is reversed and reset, the volume of the annular compressed air chamber increases.

[0068] Four vents 14 are provided on the docking end face of the dummy track 1 facing the real track. The four vents 14 are located near the upper left, lower left, upper right, and lower right corners of the docking end face, respectively, and correspond to the raceway inlet areas on both sides of the real track. The air inlet end of each vent 14 opens into the end of the moving groove near the cover plate 9 and communicates with the annular compressed air chamber. Due to the limitations of the observation direction and sectioning position, the attached figure only shows the visible vents 14. The vents 14 not shown are arranged according to the above-described four-corner correspondence.

[0069] The central axis of each exhaust port 14 is inclined to the corresponding outer edge relative to the length direction of the dummy track 1. Its projection on the docking end face points from the center of the docking end face to the corresponding outer edge: the upper left exhaust port faces the upper left, the lower left exhaust port faces the lower left, the upper right exhaust port faces the upper right, and the lower right exhaust port faces the lower right. The axial component of the exhaust airflow impacts and loosens the dust and debris at the end face of the real track and the inlet of the raceway, while the outward component carries the debris away from the docking center and the sliding block passage area. The four airflows are symmetrically distributed, which can also reduce the reaction offset caused by the blowing dead angle and the airflow on one side.

[0070] The exhaust port 14 can consist of an inlet section and a jet section. The diameter of the jet section gradually decreases along the exhaust direction. A dustproof structure can be installed inside the exhaust port 14. For example, the inlet diameter can be 1.0-1.5 mm, and the outlet diameter can be 0.5-0.8 mm to increase the jet velocity under limited compressed air stroke. The exhaust port 14 can be formed by drilling or embedding micro-nozzles. When embedding nozzles, the nozzles can be fixed by threads or interference fit, and sealant can be applied at the connection. The above dimensions can be adjusted according to the effective stroke of the adsorption block 11 and the volume of the annular compressed air chamber.

[0071] The magnetic attraction force of the true track on the adsorption block 11 is Fm, the restoring force of the elastic element 12 is Fr, the elastic force of the spring in the movable groove is Fs, the sliding resistance of the adsorption block 11 in the moving groove is f1, the sliding resistance of the limiting block 10 in the sliding groove is f2, the maximum compression resistance of the annular compression chamber during the compression stroke is Fp, the resistance of the limiting block 10 when it is lifted and referred to the moving direction of the adsorption block 11 via the wedge-shaped inclined surface is Fh, and the restoring air intake resistance is Fa. The forces can be selected and matched according to the following relationships: Triggering condition: Fm > Fr + f1 + f2 + Fp, to ensure that when the false track 1 approaches the true track, the adsorption block 11 can overcome the reset force, sliding resistance and compressive resistance to move towards the true track and output an effective purging airflow; Reset condition: Fr>f1+Fh+Fa, to ensure that after the false track 1 separates from the true track, the elastic element 12 can drive the adsorption block 11 and the push block 13 back to the reset position and re-lift the limit block 10; Retraction condition: Fs > f2. When push block 13 separates from limit block 10, ensure that the spring can drive limit block 10 to move down to the retracted position.

[0072] It should be noted that, to ensure the long-term reliability of this tooling, the wear and lubrication status of the scraper 6 and wiping component 7 should be checked regularly during use. Worn parts should be replaced promptly and lubricating oil replenished. Simultaneously, the spring force in the movable groove, the clearance at the shaft connection, the wear at the seal of the annular pressure chamber, and whether each exhaust port 14 is blocked should be checked. Without disassembling the adsorption block 11, low-pressure clean air can be introduced through the exhaust port 14 to clear any blockages.

[0073] The specific operation process of the present invention is as follows: Before use, the slider is installed outside the dummy track 1. At this time, the dummy track 1 has not yet been connected to the real track. The adsorption block 11 is in the reset position under the action of the elastic member 12. The first wedge-shaped inclined surface of the push block 13 contacts the second wedge-shaped inclined surface at the bottom of the limiting block 10 and lifts the limiting block 10 to the extended position. The limiting block 10 and the stop block 8 are located on both sides of the slider's axial direction, thereby restricting the slider on the dummy track 1.

[0074] During assembly, rotate the first connecting rod 2 and the second connecting rod 3 to move the first guide block 4 and the second guide block 5 to both sides of the true track. Insert the insert 501 on the second guide block 5 into the slot 401 on the first guide block 4, and lock the two together with a fixing pin or bolt so that the first guide block 4 and the second guide block 5 together form a contour channel.

[0075] Subsequently, the dummy track 1 is brought closer to the real track along the length of the real track. After the real track enters the contour channel, the first guide block 4 and the second guide block 5 guide the real track together, so that the relative positions of the dummy track 1 and the real track gradually correspond. During the relative movement of the two, the scraper 6 first contacts the starting section of the real track and scrapes off the assembly impurities on its surface. The wiping part 7 then releases a small amount of lubricating oil on the cleaned surface of the real track.

[0076] When the docking end of the dummy track 1 approaches the end face of the real track, the adsorption part of the adsorption block 11 is magnetically attracted by the real track, causing the sliding part and the push block 13 to move towards the real track against the restoring force of the elastic element 12. The sliding part moves closer to the cover plate 9, reducing the volume of the annular air chamber, and the air in the chamber is accelerated out through the four exhaust holes 14; the exhaust airflow is directed outward at the four corners of the docking end face and the corresponding raceway inlet area, with its axial component used to impact and loosen residual debris, and its outward component used to carry debris away from the docking center and the slider passage area. At the same time, the first wedge-shaped inclined surface of the push block 13 gradually separates from the second wedge-shaped inclined surface of the limiting block 10, and the limiting block 10 moves down to the retracted position under the action of the spring in the movable groove, thereby releasing the axial restriction on the slider while completing the end face blowing.

[0077] After the dummy track 1 and the real track are connected end to end (the dummy track 1 can be held by hand, only for auxiliary stability), push the slider to smoothly transfer the slider from the dummy track 1 to the starting section of the real track that has been cleaned and lubricated. During the pushing process, pay attention to the change in resistance of the slider movement: if the resistance is uniform and there is no obvious jamming, it indicates that the transition is smooth; if there is a significant increase in resistance or jamming near the docking position, stop pushing immediately and check whether the scraper 6 is excessively squeezing the surface of the real track or whether there are burrs or other foreign objects at the end of the real track.

[0078] After the slider transfer is completed, remove the fixing parts used to connect the slot 401 and the insert 501, and rotate the first connecting rod 2 and the second connecting rod 3 to both sides respectively, so that the first guide block 4 and the second guide block 5 separate and exit the slider's movement path. Then, move the dummy track 1 away from the real track. When the magnetic attraction decreases until it disappears, the elastic element 12 drives the adsorption block 11 and the push block 13 to move to the reset position, and the volume of the annular air chamber increases accordingly. Outside air enters the annular air chamber through the four exhaust holes 14 to replenish air for the next purging. At the same time, the push block 13, through the cooperation of the first wedge-shaped inclined surface and the second wedge-shaped inclined surface, pushes the limiting block 10 back to the extended position, so that the limiting component returns to the locked state.

[0079] When the slider or the real track needs to be inspected and maintained, the dummy track 1 can be connected to the real track first, so that the limit block 10 retracts automatically. Then the slider is transferred from the real track to the dummy track 1. After the slider is transferred, the dummy track 1 is separated from the real track. The limit block 10 moves back to the extended position with the reset of the magnetic control linkage mechanism and cooperates with the stop block 8 to axially limit the slider, thereby preventing the slider from accidentally falling off the dummy track 1, which facilitates the carrying, transportation and subsequent maintenance of the slider.

[0080] It should be noted that the magnetic linkage mechanism described in this tooling is based on the principle of permanent magnet adsorption and is mainly applicable to assembly scenarios where the actual track material is ferromagnetic. If the actual track material is non-magnetic or weakly magnetic, then the electromagnet alternative solution described in this manual must be used.

[0081] The present invention has been described by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
