Description

Technical Field

[0001] This invention relates to the field of linear guide technology, specifically to a linear guide slider with a protective structure. Background Technology

[0002] Linear guide sliders are the core moving components of linear guide systems. They are used in conjunction with guide rails and are widely applied in fields such as automation equipment, machine tools, and precision instruments. Through built-in ball, roller, or sliding contact structures, they achieve high-precision linear reciprocating motion along the guide rail, effectively reducing the coefficient of friction and improving operational stability.

[0003] Currently, most linear guide sliders use a single ball bearing in conjunction with the guide rail raceway, lacking a radial limiting reinforcement design. Under high-speed reciprocating motion or lateral loads, radial displacement of the slider is prone to occur. This not only causes the motion trajectory to deviate from the preset path and reduces transmission accuracy, but also exacerbates local wear between the ball bearing and the raceway, leading to slider jamming, abnormal noise, and other malfunctions, making it difficult to meet the requirements of high-precision equipment. Therefore, we propose a linear guide slider with a protective structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a linear guide slider with a protective structure. This solves the problem that existing guide sliders often use a single ball bearing in conjunction with the guide rail raceway, lacking a radial limiting reinforcement design. Under high-speed reciprocating motion or lateral loads, radial displacement of the slider is prone to occur. This not only causes the motion trajectory to deviate from the preset path and reduces transmission accuracy, but also exacerbates local wear of the ball bearing and raceway, leading to slider jamming, abnormal noise, and other malfunctions, making it difficult to meet the requirements of high-precision equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a linear guide rail slider with a protective structure, comprising a guide rail body and a slider body, wherein the slider body is sleeved on the guide rail body, the upper surface of the guide rail body has an installation groove, the upper surface of the slider body has an assembly groove, a positioning mechanism is provided on the surface of the slider body, the positioning mechanism includes a locking block, the locking block is fixedly connected to the inner side of the slider body, two symmetrically arranged guide strips are fixedly connected to the surface of the guide rail body, a guide block is fixedly connected to the inner wall of the slider body, the guide block slides on the surface of the guide strips, guide grooves are provided on both sides of the guide rail body, the locking block slides on the inner side of the guide grooves, a positioning groove is provided on the inner side of the slider body, a ball is rotatably connected to the inner wall of the positioning groove, the ball rolls against the surface of the guide strips. The sliding block body features a dynamic contact mechanism on both sides for detecting the gap between its inner side and the guide rail body. The lower surface of the sliding block body also has an adjustment mechanism for adjusting this gap. Utilizing the spring preload and real-time contact structure of the detection mechanism with the abutment wheel, the gap change between the slider and guide rail can be dynamically monitored. Combined with the intuitive display on the scale plate, operators can quickly grasp the fit and complete the gap detection without disassembly. The detection mechanism also supports manual pulling of the lever to separate the abutment wheel, facilitating calibration and maintenance. Upon release, the spring drives the abutment wheel to automatically reset, ensuring the stability of the detection accuracy. When the gap is too large, the adjustment mechanism drives the guide wheel through a threaded transmission to generate precise support force, allowing for minor deformation of the slider to fine-tune the gap, effectively compensating for accuracy loss due to wear and maintaining optimal fit over the long term.

[0006] Preferably, the detection mechanism includes a sliding hole on one side of the slider body, a receiving groove on the inner wall of the slider body, the sliding hole communicating with the receiving groove, a pull rod slidably connected in the sliding hole, a carrier fixedly connected to one end of the pull rod in the receiving groove, the carrier sliding against the inner wall of the receiving groove, two symmetrically arranged abutment wheels rotatably connected to the inner wall of the carrier, one side of the abutment wheel abutting against the surface of the guide rail body, a first level ruler installed on one side of the slider body, and a second level ruler installed on one side of the slider body.

[0007] Preferably, a spring is fixedly connected to one side of the carrier, the spring is located in the storage groove, and the end of the spring away from the carrier is fixedly connected to the inner wall of the storage groove.

[0008] Preferably, a scale plate is fixedly connected to the side of the carrier near the pull rod, and a stabilizing hole is opened on the side of the slider body near the sliding hole. The stabilizing hole is connected to the storage groove, and the end of the scale plate away from the carrier slides against the inner wall of the stabilizing hole. The visual scale design and convenient calibration structure of the detection mechanism reduce the difficulty of gap detection and maintenance and shorten the time cost.

[0009] Preferably, the adjustment mechanism includes a slide groove, which is located on the lower surface of the slider body. A carrier block is slidably connected to the inner wall of the slide groove, and a guide wheel is rotatably connected to the lower surface of the carrier block. One side of the guide wheel contacts the surface of the guide rail body. The adjustment mechanism dynamically calibrates the gap, and the cleaning mechanism provides full protection, forming a complete precision assurance and protection closed loop. This allows the slider to operate stably under complex working conditions such as dust and wear. At the same time, its structural design takes into account both manual maintenance and automatic adjustment, adapting to transmission scenarios with different precision requirements, and thus has stronger applicability.

[0010] Preferably, a positioning hole is provided on one side of the slider body, which is connected to the slide groove. An adjusting rod is rotatably connected in the positioning hole. One end of the adjusting rod passes through the carrier block and is rotatably connected to the inner wall of the slide groove. The adjusting rod is threaded on the surface of the adjusting rod in the slide groove and is threadedly connected to the inner wall of the carrier block. During the movement of the slider, the detection mechanisms on both sides monitor the change in the gap between the inner side of the slider and the guide rail body in real time, providing a precise basis for gap adjustment. Specifically, under the elastic force of the spring, the carrier always drives the two abutment rollers on its inner wall to be in close contact with the surface of the guide rail body. When the gap between the slider and the guide rail changes due to wear or other factors, the abutment rollers will push the carrier to slide in the storage groove as the gap changes. When the carrier slides, it will simultaneously drive the scale plate to slide in the stabilizing hole. The operator can intuitively judge the size of the gap by observing the change in the length of the scale plate extending out of the stabilizing hole. If manual detection or calibration is required, the pull rod can be pulled to drive the carrier to compress the spring, so that the abutment rollers are separated from the surface of the guide rail. Then, the hand is released, and the spring pushes the carrier and the abutment rollers back to their original positions.

[0011] Preferably, both sides of the slider body are provided with cleaning mechanisms for cleaning dust inside the guide groove. The cleaning mechanism adopts a cleaning mode of mechanical scraping combined with high-pressure air blowing. The triangular scraper can efficiently scrape off large particles of impurities in the guide groove, and the high-pressure gas is guided by the baffle to accurately impact small residual impurities, thus avoiding wear and jamming caused by impurities entering the positioning and guiding structure in all aspects. The stable support of the card seat for the guide tube ensures a continuous supply of cleaning gas, further improving the reliability of protection, significantly reducing the wear rate of components, and extending the overall service life of the guide rail and slider.

[0012] Preferably, the cleaning mechanism includes a shovel block, which is fixedly installed on one side of the clamping block. An air vent is provided on the side of the shovel block. A stabilizing block is fixedly connected to the surface of the shovel block. A conduit is detachably installed on the side of the stabilizing block away from the shovel block. A connector for supplying high-pressure gas is installed on the conduit, and the connector is connected to the air vent via the conduit. The adjustment mechanism allows for gap adjustment by simply rotating an adjusting rod, without the need for specialized or complex tools. The fixed installation of the shovel block and the detachable design of the conduit facilitate subsequent replacement of cleaning components and maintenance of the conduit, thereby reducing the overall difficulty of equipment operation and maintenance and the cost of use.

[0013] Preferably, the cross-section of the shovel block is triangular, and a baffle plate is fixedly connected to the side of the shovel block near the air outlet. The baffle plate is used to guide the high-pressure gas ejected from the air outlet to impact the guide groove. When the detection mechanism reports that the gap is too large, the adjustment mechanism on the lower surface of the slider body will actively intervene to adjust it. By rotating the adjustment rod, the thread on the surface of the adjustment rod and the thread of the carrier block are used to drive the carrier block to slide axially along the guide rail in the groove. When the carrier block slides, it drives the guide wheel on its lower surface to move synchronously. The guide wheel contacts the surface of the guide rail body to generate an upward supporting force, which is transmitted to the slider body through the carrier block, causing the slider body to produce a small radial deformation, thereby reducing the gap between the slider and the guide rail and restoring the best fit accuracy.

[0014] Preferably, two symmetrically arranged brackets are fixedly connected to one side of the guide rail body. The guide tube is installed inside the brackets to support the guide tube, ensuring stable use of the equipment. All mechanisms work closely together and are seamlessly connected. Positioning and guidance ensure the accuracy of the motion foundation, and the detection mechanism monitors the status in real time.

[0015] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, by utilizing the spring preload and real-time contact structure of the abutment wheel in the detection mechanism, the gap change between the slider and the guide rail can be dynamically monitored. With the intuitive display of the scale plate, the operator can quickly grasp the fit status and complete the gap detection without disassembly. At the same time, the detection mechanism supports manual pulling of the lever to separate the abutment wheel, which is convenient for calibration and maintenance. After releasing the lever, the spring can drive the abutment wheel to automatically reset, ensuring the stability of the detection accuracy. When the gap is too large, the adjustment mechanism drives the guide wheel through the screw drive to generate precise support force, so that the slider undergoes slight deformation to achieve fine adjustment of the gap, effectively compensating for the accuracy loss caused by wear and maintaining the best fit status in the long term.

[0016] 2. In this invention, the cleaning mechanism adopts a cleaning mode of mechanical scraping combined with high-pressure air blowing. The triangular shovel can efficiently scrape off large particles of impurities in the guide groove, and the high-pressure gas is guided by the baffle to accurately impact small residual impurities, thus avoiding wear and jamming caused by impurities entering the positioning and guiding structure in all aspects. The stable support of the card seat for the guide tube ensures a continuous supply of cleaning gas, further improving the reliability of protection, significantly reducing the wear rate of components, and extending the overall service life of the guide rail and slider.

[0017] 3. In this invention, the various mechanisms work closely together and are seamlessly connected. The positioning and guidance ensures the basic accuracy of the motion, the detection mechanism monitors the status in real time, the adjustment mechanism dynamically calibrates the gap, and the cleaning mechanism provides full protection, forming a complete closed loop of accuracy assurance and protection. This allows the slider to operate stably even under complex working conditions such as dust and wear. At the same time, its structural design takes into account both manual maintenance and automatic adjustment, adapting to transmission scenarios with different accuracy requirements, making it more versatile.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] refer to Figures 1-9 The linear guide slider with a protective structure shown includes a guide rail body 1 and a slider body 2. The slider body 2 is sleeved on the guide rail body 1. The upper surface of the guide rail body 1 has a mounting groove 3, and the upper surface of the slider body 2 has an assembly groove 4. A positioning mechanism 5 is provided on the surface of the slider body 2. The positioning mechanism 5 includes a locking block 51, which is fixedly connected to the inner side of the slider body 2. Two symmetrically arranged guide strips 55 are fixedly connected to the surface of the guide rail body 1. A guide block 52 is fixedly connected to the inner wall of the slider body 2 and slides on the surface of the guide strips 55. Guide grooves 56 are provided on both sides of the guide rail body 1, and the locking block 51 slides on the inner side of the guide grooves 56. A positioning groove 53 is provided on the inner side of the slider body 2, and a ball bearing 54 is rotatably connected to the inner wall of the positioning groove 53. The ball bearing 54 rolls in contact with the surface of the guide strips 55. A positioning groove 53 is provided on both sides of the slider body 2. The system includes a detection mechanism 6 for detecting the gap between the inner side of the slider body 2 and the guide rail body 1. An adjustment mechanism 7 is provided on the lower surface of the slider body 2 to adjust the gap between the inner side of the slider body 2 and the guide rail body 1. With the pre-tensioning of the spring 65 in the detection mechanism 6 and the real-time contact structure with the abutment wheel 63, the gap change between the slider and the guide rail can be dynamically monitored. Combined with the intuitive display on the scale plate 66, operators can quickly grasp the fit status and complete the gap detection without disassembly. Simultaneously, the detection mechanism 6 supports manual pulling of the pull rod 61 to separate the abutment wheel 63, facilitating calibration and maintenance. After releasing the lever, the spring 65 can drive the abutment wheel 63 to automatically reset, ensuring the stability of the detection accuracy. When the gap is too large, the adjustment mechanism 7 drives the guide wheel 75 through threaded transmission to generate precise support force, causing a slight deformation of the slider to achieve fine-tuning of the gap, effectively compensating for the accuracy loss caused by wear and maintaining the optimal fit status over a long period.

[0022] The detection mechanism 6 includes a sliding hole 67 on one side of the slider body 2, a storage groove 64 on the inner wall of the slider body 2, the sliding hole 67 and the storage groove 64 being connected, a pull rod 61 being slidably connected in the sliding hole 67, a carrier 62 being fixedly connected to one end of the pull rod 61 in the storage groove 64, the carrier 62 sliding against the inner wall of the storage groove 64, and two symmetrically arranged abutment rollers 63 being rotatably connected to the inner wall of the carrier 62, one side of the abutment rollers 63 abutting against the surface of the guide rail body 1, a first level 76 being installed on one side of the slider body 2, and a second level 77 being installed on one side of the slider body 2.

[0023] A spring 65 is fixedly connected to one side of the carrier 62. The spring 65 is located in the storage groove 64, and the end of the spring 65 away from the carrier 62 is fixedly connected to the inner wall of the storage groove 64.

[0024] Among them, a scale plate 66 is fixedly connected to the side of the carrier 62 near the pull rod 61, and a stabilizing hole 68 is opened on the side of the slider body 2 near the sliding hole 67. The stabilizing hole 68 is connected to the storage groove 64. The end of the scale plate 66 away from the carrier 62 slides against the inner wall of the stabilizing hole 68. The visual scale design and convenient calibration structure of the detection mechanism 6 reduce the difficulty of gap detection and maintenance and shorten the time cost.

[0025] The adjustment mechanism 7 includes a slide groove 71, which is located on the lower surface of the slider body 2. A carrier block 74 is slidably connected to the inner wall of the slide groove 71, and a guide wheel 75 is rotatably connected to the lower surface of the carrier block 74. One side of the guide wheel 75 contacts the surface of the guide rail body 1. The adjustment mechanism 7 dynamically calibrates the gap, and the cleaning mechanism 8 provides full protection, forming a complete precision assurance and protection closed loop. This allows the slider to operate stably under complex working conditions such as dust and wear. At the same time, its structural design takes into account both manual maintenance and automatic adjustment, adapting to transmission scenarios with different precision requirements, making it more versatile.

[0026] The slider body 2 has a positioning hole 72 on one side, which is connected to the slide groove 71. An adjusting rod 73 is rotatably connected to the positioning hole 72. One end of the adjusting rod 73 passes through the carrier block 74 and is rotatably connected to the inner wall of the slide groove 71. The surface of the adjusting rod 73 in the slide groove 71 is threaded, and the adjusting rod 73 is threaded to the inner wall of the carrier block 74. During the movement of the slider, the detection mechanisms 6 on both sides monitor the change in the gap between the inner side of the slider and the guide rail body 1 in real time, providing a precise basis for gap adjustment. Specifically, under the elastic force of the spring 65, the carrier 62 always drives the inner side of the slider. The two abutment rollers 63 on the wall are in close contact with the surface of the guide rail body 1. When the gap between the slider and the guide rail changes due to wear or other factors, the abutment rollers 63 will push the carrier 62 to slide in the storage groove 64 as the gap changes. When the carrier 62 slides, it will simultaneously drive the scale plate 66 to slide in the stabilizing hole 68. The operator can intuitively judge the size of the gap by observing the change in the length of the scale plate 66 extending out of the stabilizing hole 68. If manual testing or calibration is required, the pull rod 61 can be pulled to drive the carrier 62 to compress the spring 65, so that the abutment rollers 63 are separated from the surface of the guide rail. Then, the spring 65 will push the carrier 62 and the abutment rollers 63 to reset.

[0027] The slider body 2 is equipped with cleaning mechanisms 8 on both sides for cleaning dust inside the guide groove 56. The cleaning mechanism 8 adopts a cleaning mode of mechanical scraping combined with high-pressure air blowing. The triangular scraper 81 can efficiently scrape off large particles of impurities inside the guide groove 56. The high-pressure gas is guided by the baffle 84 to accurately impact small residual impurities, thus avoiding wear and jamming caused by impurities entering the positioning and guiding structure. The stable support of the bracket 87 to the guide tube 83 ensures a continuous supply of cleaning gas, further improving the reliability of protection, significantly reducing the wear rate of components, and extending the overall service life of the guide rail and slider.

[0028] The cleaning mechanism 8 includes a shovel block 81, which is fixedly installed on one side of the clamping block 51. An air outlet 85 is provided on the side of the shovel block 81. A stabilizing block 82 is fixedly connected to the surface of the shovel block 81. A conduit 83 is detachably installed on the side of the stabilizing block 82 away from the shovel block 81. A connector 86 for supplying high-pressure gas is installed on the conduit 83. The connector 86 is connected to the air outlet 85 through the conduit 83. The adjustment mechanism 7 can adjust the gap by simply rotating the adjusting rod 73 without the need for professional and complicated tools. The fixed installation of the shovel block 81 and the detachable design of the conduit 83 of the cleaning mechanism 8 facilitates the replacement of cleaning components and the maintenance of the conduit 83, thereby reducing the overall difficulty of equipment operation and maintenance and the cost of use.

[0029] The shovel block 81 has a triangular cross-section. A baffle plate 84 is fixedly connected to the side of the shovel block 81 near the air outlet 85. The baffle plate 84 is used to guide the high-pressure gas ejected from the air outlet 85 to impact the guide groove 56. When the feedback gap from the detection mechanism 6 is too large, the adjustment mechanism 7 on the lower surface of the slider body 2 will actively intervene to adjust it. By rotating the adjustment rod 73, the screw thread on the surface of the adjustment rod 73 and the screw thread of the carrier block 74 are used to drive the carrier block 74 to slide axially along the guide rail in the slide groove 71. When the carrier block 74 slides, it drives the guide wheel 75 on its lower surface to move synchronously. The guide wheel 75 contacts the surface of the guide rail body 1 to generate an upward supporting force, which is transmitted to the slider body 2 through the carrier block 74, causing the slider body 2 to produce a small radial deformation, thereby reducing the gap between the slider and the guide rail and restoring the best fit accuracy.

[0030] Among them, two symmetrically arranged brackets 87 are fixedly connected to one side of the guide rail body 1. The guide tube 83 is installed inside the bracket 87 to support the guide tube 83 and ensure stable use of the equipment. All mechanisms work closely together and are seamlessly connected. The positioning and guidance ensure the accuracy of the motion foundation, and the detection mechanism 6 monitors the status in real time.

[0031] Working principle of the invention: The slider body 2 is sleeved on the outside of the guide rail body 1. First, the positioning mechanism 5 completes the basic guarantee of precise guidance and low resistance movement. The locking block 51 fixed inside the slider body 2 is embedded in the guide groove 56 on both sides of the guide rail body 1. The sliding cooperation between the locking block 51 and the guide groove 56 restricts the displacement of the slider along the radial direction of the guide rail, ensuring that the slider can only move in a straight line along the axial direction of the guide rail. At the same time, the two symmetrical guide bars 55 on the surface of the guide rail body 1 and the ball 54 rotatably connected in the positioning groove 53 inside the slider body 2 form rolling contact, converting the sliding friction between the slider and the guide rail into rolling friction, which greatly reduces the movement resistance while improving the smoothness and accuracy of the movement. During the movement of the slider, the detection mechanisms 6 on both sides monitor the change in the gap between the inner side of the slider and the guide rail body 1 in real time, providing a precise basis for gap adjustment. Specifically, under the elastic force of the spring 65, the carrier 62 always drives the two abutment rollers 63 on its inner wall to be in close contact with the surface of the guide rail body 1. When the gap between the slider and the guide rail changes due to wear and other factors, the abutment rollers 63 will push the carrier 62 to slide in the storage groove 64 as the gap changes. When the carrier 62 slides, it will simultaneously drive the scale plate 66 to slide in the stabilizing hole 68. The operator can intuitively judge the size of the gap by observing the change in the length of the scale plate 66 extending out of the stabilizing hole 68. If manual detection or calibration is required, the pull rod 61 can be pulled to drive the carrier 62 to compress the spring 65, so that the abutment rollers 63 are separated from the surface of the guide rail. Then, the hand is released, and the spring 65 pushes the carrier 62 and the abutment rollers 63 to reset. When the feedback gap of the detection mechanism 6 is too large, the adjustment mechanism 7 on the lower surface of the slider body 2 will actively intervene to adjust it. By rotating the adjustment rod 73, the screw thread on the surface of the adjustment rod 73 and the screw thread of the carrier block 74 are used to drive the carrier block 74 to slide along the guide rail axis in the slide groove 71. When the carrier block 74 slides, it drives the guide wheel 75 on its lower surface to move synchronously. The guide wheel 75 contacts the surface of the guide rail body 1 to generate an upward support force, which is transmitted to the slider body 2 through the carrier block 74, causing the slider body 2 to produce a small radial deformation, thereby reducing the gap between the slider and the guide rail and restoring the best fit accuracy. Meanwhile, the cleaning mechanisms 8 on both sides of the slider body 2 continuously play a protective role, preventing impurities from affecting the stability of the movement. The triangular shovel block 81 fixed on one side of the shovel block 51 can directly scrape off the dust and larger particles attached to the inner wall of the guide groove 56 when the slider moves. At the same time, high-pressure gas enters the guide tube 83 through the connector 86 and is ejected through the air outlet 85 on the shovel block 81. The baffle plate 84 on the shovel block 81 guides the high-pressure gas to accurately impact the small impurities remaining on the inner wall of the guide groove 56 and blow them away from the guide groove 56. The shovel seat 87 on one side of the guide rail body 1 provides stable support for the guide tube 83, ensuring that the position of the guide tube 83 is stable when it moves with the slider and ensuring a continuous and stable supply of cleaning gas. Throughout the entire working process, the various mechanisms work closely together and are seamlessly connected. The positioning and guidance ensures accuracy, the detection mechanism 6 monitors the status, the adjustment mechanism 7 dynamically calibrates, and the cleaning mechanism 8 provides protection and escort, ultimately achieving high-precision and long-life linear motion of the slider.
