Description

Technical Field

[0001] The invention relates to the technical field of guide rail sliders, and in particular to a miniature guide rail slider. Background Art

[0002] Guide rails are an important mechanical structure that provides smooth and accurate motion and ensures that moving parts do not deviate or vibrate during motion. Guide rails are widely used in various mechanical systems. Their design and manufacture need to take many factors into consideration to ensure their performance and life. The slider for micro guide rails is a precision mechanical component used to achieve linear motion and positioning in micro guide rail systems.

[0003] In the use of micro guide rail sliders, the sliders are often worn due to long-term use. After wear, the accuracy is reduced, and it is easy to wobble, which reduces the smoothness of movement and increases the noise. Therefore, the slider needs to be replaced. When the slider is replaced, if both ends of the guide rail are blocked, the guide rail needs to be disassembled together, which makes replacement very troublesome. At the same time, the disassembly of the guide rail is also likely to affect the accuracy of the guide rail installation position, which increases the subsequent debugging time, resulting in low maintenance efficiency.

[0004] Therefore, a miniature guide rail slider is now proposed, which can directly replace the slider without disassembling the guide rail. Summary of the invention

There is no need to install or remove the guide rail from the end of the guide rail. The operation is simple and quick. When replacing the slider, even if the two ends of the guide rail are blocked or multiple sliders are installed, it can be directly replaced from the middle, which greatly improves the installation and replacement efficiency, reduces the impact on the installation position accuracy of the guide rail, and reduces the subsequent debugging time.

[0025] 2. The height of the undulating component can be accurately adjusted by adjusting the bolts, thereby changing the pressure on the force-bearing surface, and achieving fine-tuning of the telescopic length of the telescopic component, ensuring that the connection depth and extrusion strength between the connection unit and the slide groove are appropriate, ensuring the smooth movement of the slider on the slide rail, avoiding looseness or excessive friction, and increasing the service life of the slider.

[0027] 4. The spring of the reset component is flexibly connected to the movable plate through the fixed component. When the slider is not installed or the pressure on the force surface is reduced, the spring can push the movable plate and the connection unit to reset, so that the slider can be easily mounted on the guide rail when not installed.

DETAILED DESCRIPTION

[0043] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Refer to the instruction manual Figure 1-Figure 12 As shown, a miniature guide rail slider comprises:

[0045] A slide rail body 1, with slide grooves 2 provided on both sides of the slide rail body 1;

[0046] A slider housing 3, wherein telescopic components 6 are symmetrically mounted inside the slider housing 3, each telescopic component 6 is mounted with a fixing component 8, and a reset component 15 is symmetrically mounted on the slider housing 3 at the bottom of each telescopic component 6, and each reset component 15 is connected to the telescopic component 6 through the corresponding fixing component 8;

[0047] The telescopic assembly 6 includes a moving plate 601, a connecting unit 602, a blocking member 603, a bead groove 604 and a connecting groove 605. The moving plate 601 has a bead groove 604 on one side. The connecting unit 602 is rotatably arranged in the bead groove 604. A connecting groove 605 is arranged at one end of the bead groove 604. The blocking member 603 is installed in the connecting groove 605. A force-bearing surface 10 is arranged on the top of the moving plate 601. The force-bearing surface 10 is in an inclined structure.

[0048] The ups and downs component 7, the bottom ends of both sides of the ups and downs component 7 are respectively slidably connected with the corresponding force-bearing surfaces 10, and the middle of the ups and downs component 7 is plugged with an adjusting bolt 4 that is screwed with the slider housing 3;

[0049] A top cover 5, the top cover 5 is mounted on the top of the slider housing 3;

[0050] The adjusting bolt 4 is used to adjust the height of the undulating component 7. The undulating component 7 changes the pressure on the force-bearing surfaces 10 on both sides of the bottom by changing the height. The force-bearing surfaces 10 adjust the telescopic length of the telescopic component 6 by being subjected to different pressures. The reset component 15 connected to each telescopic component 6 is used to telescope and reset the telescopic component 6. When the force-bearing surfaces 10 are subjected to the pressure of the undulating component 7, the connecting unit 602 can be moved out of the slider housing 3 to connect with the slide groove 2.

[0051] During the specific implementation, the overall structure of the slider is assembled:

[0052] First, each reset component 15 is installed and fixed in the corresponding installation groove 14 respectively, and then the telescopic component 6 is inserted from the guide channel 16. The telescopic component 6 enters the installation groove 14 under the guidance of the guide channel 16, and the bottom groove 9 is moved to the top of the reset component 15 and pushed to the bottom, so that the bottom groove 9 is against the end of the reset component 15, and then each fixed component 8 is respectively inserted into the corresponding slot 11, so that the fixed component 8 is inserted into the spring provided in the telescopic component 6 and is flexibly clamped by the spring. The movable plate 601 can be randomly moved, and the spring can be extended and retracted, and the movable plate 601 can be automatically reset. At the same time, the force-bearing surface 10 opened on the top of each movable plate 601 is at the same distance from the groove wall of the nearby installation groove 14, so as to ensure the installation of the ups and downs component 7, so that the ups and downs component 7 can be slidably connected with the force-bearing surface 10, and when the ups and downs component 7 is ups and downs, the two telescopic components 6 are synchronously extended and retracted to the same length, so as to ensure the two When the connecting unit 602 is connected to the slide groove 2, it can be connected synchronously, and then the fixing component 8 is fixed, so that when the spring in the reset component 15 is in a free state, the entire telescopic component 6 is contracted inside the guide channel 16, and then the ups and downs component 7 is placed in the lifting groove 12, so that the through hole and the screw groove 13 are coaxially aligned. At the same time, the pressure plates 702 on both sides are slidably connected with the upper side of the force-bearing surface 10, and the bottom of the adjusting bolt 4 is passed through the through hole and connected with the screw groove 13 at the bottom. The adjusting bolt 4 is appropriately rotated to slightly press the ups and downs component 7 while ensuring that the connecting unit 602 does not protrude outside the guide channel 16. Then, the top cover 5 is installed to complete the assembly of the slider. The installation is convenient, and the layout of each structure is reasonable. When the slider is assembled, the installation accuracy of the slider can be adjusted. When installing it on the slide rail, it only needs to adjust the tightness, which also improves the replacement efficiency when the slider needs to be replaced later.

[0053] When installing the slider on the slide rail: directly put the slider on the slide rail body 1, and then rotate the adjusting bolt 4 clockwise so that the adjusting bolt 4 presses down the undulating component 7, so that the extrusion surface is squeezed against the force-bearing surface 10, so that the extrusion surface and the force-bearing surface 10 slide relative to each other, and the connecting units 602 installed on the two movable plates 601 approach the slide groove 2 at the same time and enter the slide groove 2, and by fine-tuning the adjusting bolt 4, the sliding smoothness between the connecting unit 602 and the slide groove 2, and the firmness of the slider are adjusted, so that the slider can be simply installed on the slide rail body 1, the operation is simple and fast, and there is no need to disassemble the slide rail body 1, nor is there any need to install the slider from the end of the slide rail body 1, especially when multiple sliders are installed on a slide rail and the middle slider needs to be replaced, it can be installed directly from the middle, and there is no need to disassemble other sliders, which greatly improves the replacement efficiency of the slider.

[0054] The slider housing 3 has symmetrical mounting grooves 14 , a lifting groove 12 is connected between the two mounting grooves 14 , a screw groove 13 is formed in the middle of the bottom end of the lifting groove 12 , and a guide channel 16 is formed inside each mounting groove 14 .

[0055] A reset component 15 is symmetrically installed in each installation groove 14, and a movable plate 601 slidably connected to the guide channel 16 is arranged at the top of each reset component 15. A bottom groove 9 is symmetrically opened at the bottom of each movable plate 601. The top of the two bottom grooves 9 is connected to a slot 11 opened on the movable plate 601, and a fixed component 8 is installed in the slot 11. The fixed component 8 is plugged into the slot 11 and connected to the end of each reset component 15 arranged in the bottom groove 9.

[0056] In the specific implementation, the movable plate 601 is slid from the guide channel 16 into the installation slot 14, so that the bottom slot 9 is moved to the top of the reset component 15, and then the fixed component 8 is installed in the slot 11, so that the bottom plug-in plate 801 is plugged into the spring, so that the spring clamps the plug-in plate 801, so that the spring is connected to the movable plate 601. When the spring is free, the connecting unit 602 installed on the movable plate 601 is hidden in the guide channel 16. When the force-bearing surface 10 is subjected to pressure, when the movable plate 601 is moved out of the guide channel 16, one end of the spring is fixed due to the pressure. The component 8 is fixed so that the spring is compressed to accumulate potential energy. When the force on the force-bearing surface 10 is reduced, the spring potential energy is released and extends, thereby moving the movable plate 601 and the connecting unit 602 into the guide channel 16 again. Therefore, when the slider is not installed on the guide rail, the slider can be directly sleeved on the guide rail, and there is no need to install the slider from the end of the guide rail along the slide groove 2, thereby improving the convenience of slider installation. When installing or replacing the slider, there is no need to disassemble the guide rail, thereby improving installation efficiency and reducing the debugging of the guide rail installation position, thereby improving maintenance efficiency.

[0057] The undulating component 7 includes a crossbeam 701 and a pressure plate 702. A through hole coaxially arranged with the screw groove 13 is opened in the middle of the crossbeam 701. The adjusting bolt 4 passes through the through hole and is connected to the screw groove 13 at the bottom. The two sides of the crossbeam 701 are slidably connected to the inner wall of the lifting groove 12. Pressure plates 702 are vertically arranged at both ends of the crossbeam 701. An extrusion surface is opened at the bottom of each pressure plate 702, and the extrusion surface is slidably connected to the force-bearing surface 10.

[0058] In specific implementation, by rotating the adjusting bolt 4, the adjusting bolt 4 is made to descend along the screw groove 13, so that the head of the adjusting bolt 4 presses down the cross beam 701, and the cross beam 701 is slidably connected to the lifting groove 12, so that the pressure plates 702 at both ends are vertically descended with the cross beam 701, so that in the process of the pressure plate 702 descending, the extrusion surface and the force-bearing surface 10 slide, and the position of the pressure plate 702 is fixed by the cross beam 701, and the movable plate 601 is flexibly connected to the spring, so that the movable plate 601 can move along the guide channel 16, so that the two movable plates 601 are close to each other, so that the two connecting units 60 2 are respectively moved into the slide grooves 2 on both sides of the slide rail body 1, so that the slide block can be installed on the guide rail by connecting the connecting unit 602 with the slide rail body 1. By adjusting the height of the adjusting bolt 4, the connecting depth and the extrusion strength between the connecting unit 602 and the slide groove 2 can be adjusted, so as to facilitate the adjustment of the smoothness of the connecting unit 602 when moving, so as to avoid the connecting unit 602 being too loose or causing excessive friction due to excessive extrusion force, thereby causing poor smoothness of the movement of the slide block and accelerated wear. In this way, the smoothness can be adjusted according to the demand, and wear caused by excessive friction can be avoided, so as to also improve the service life of the slide block.

[0059] The connecting unit 602 is a plurality of steel balls arranged in a line, and the steel balls are restricted in the ball grooves 604 by the blocking member 603 .

[0060] During specific implementation, the connection strength between the steel balls can be adjusted by adjusting the tightness of the blocking member 603, thereby ensuring the smooth rotation of the steel balls, thereby reducing the friction force when the steel balls roll along the slide groove 2, thereby improving the smoothness of the movement of the slider and reducing friction noise.

[0061] The blocking member 603 includes a blocking block 6031 and a fixing block 6032 . The fixing block 6032 is welded on one side of the blocking block 6031 . The blocking block 6031 is slidably connected to the inner wall of the ball groove 604 . An arc groove connected to the steel ball is provided on the inner side of the blocking block 6031 . The fixing block 6032 is bolted in the connecting groove 605 .

[0062] In a specific implementation, when installing the connection unit 602, the ball groove 604 can be filled from one end. After a certain amount of steel balls are filled, the stopper 6031 is inserted into the end of the ball groove 604, and the fixed block 6032 enters the connection groove 605. After the fixed block 6032 is fixed by the bolt, the steel balls can be prevented from rolling out. By rotating the bolt to adjust the squeezing force on the fixed block 6032, the squeezing force of the stopper 6031 on the steel balls can be adjusted, thereby adjusting the squeezing force between the steel balls, thereby ensuring the rolling connection between the steel balls and avoiding Avoid jamming due to over-tightening, and avoid collision and noise caused by rolling of the steel balls due to over-loosening. After the connection force between the steel balls is adjusted, glass glue and low bolts can be used for bonding to further improve the fixing effect, so as to ensure that the balls can be stably in the ball groove 604. The detachable design of the blocking member 603 makes it easy to replace the steel balls, thereby avoiding wear of the steel balls due to long-term use, affecting the accuracy and increasing the noise, thereby improving the convenience of maintenance and avoiding direct replacement of the entire slider.

[0063] The reset assembly 15 includes a spring and a fixing seat. The fixing seat is installed at the bottom of the installation groove 14, and one end of the spring is fixedly connected to the fixing seat.

[0064] The fixing assembly 8 includes an insert plate 801 and a fixing ear 802. The fixing ear 802 is welded on one side of the top of the insert plate 801. The insert plate 801 is inserted into the spring in the bottom groove 9 through the slot 11. The end of the spring is elastically clamped with the insert plate 801. A matching groove is opened on one side of the top of the slot 11, and the fixing ear 802 is bolted in the matching groove.

[0065] During specific implementation, the spring is fixed in the installation groove 14 by the fixing seat. When the movable plate 601 is installed, the movable plate 601 is pushed in from the guide channel 16, just so that the entire reset assembly 15 is in the bottom groove 9. Then, after the movable plate 601 is pushed completely into the guide channel 16, the plug plate 801 is plugged into the slot 11, so that the plug plate 801 is inserted into the spring gap in the bottom groove 9, so that an elastic clamp is generated between the spring and the plug plate 801, and the bottom of the bottom groove 9 is blocked by the groove surface of the installation groove 14, so that the spring will not tilt when subjected to force, so that it can be stably connected to the movable plate 601, so that when the force-bearing surface 10 opened on the top of the movable plate 601 is subjected to the pressure of the extrusion surface and produces relative sliding, the spring can be compressed, and when the force-bearing surface 10 is subjected to the force reduction When the slider is in the state of being moved, the spring potential energy is released to extend and the movable plate 601 can be pushed back to its original position. Therefore, when the entire slider structure is fully installed as a whole, the connecting unit 602 is placed in the guide channel 16 by rotating the adjusting bolt 4. When installing the slider, the slider can be directly put on from above the slide rail, and then the adjusting bolt 4 is first moved to move the connecting unit 602 out, so that the connecting unit 602 can enter the slide groove 2, so that the slider and the slide rail are slidably connected, and the slider and the slide rail are connected only by the connecting unit 602, thereby reducing the connection contact surface and reducing the sliding friction. The connecting unit 602 is composed of steel balls, and the rolling friction is used instead of the sliding friction, so that the slider moves more smoothly on the slide rail and the noise generated by sliding is reduced.

[0066] The slide groove 2 is an arc-shaped structure, and the arc center radius corresponding to the arc structure is the same as the arc center radius of the cross section of the bead groove 604 .

[0067] A debugging hole is opened in the middle of the top cover 5 , and the head of the adjusting bolt 4 is slidably connected to the debugging hole, and the top surface of the adjusting bolt 4 is lower than the upper surface of the top cover 5 .

[0068] In specific implementation, the adjusting bolt 4 can be directly rotated and adjusted through the debugging hole. When installing the slider, if the connecting unit 602 protrudes from the guide channel 16, the adjusting bolt 4 can be rotated counterclockwise to make the adjusting bolt 4 rise, thereby reducing the pressure on the undulating component 7, so that the reset component 15 pushes the moving plate 601 to reset, so that the connecting unit 602 moves to the inside of the guide channel 16, and then the slider is directly sleeved on the slide rail body 1, and then the adjusting bolt 4 is rotated clockwise to make the moving plate 601 approach the slide rail body 1. The connecting unit 602 abuts against the slide rail body 1, and the slider as a whole is properly adjusted so that the connecting unit 6 02 Align the slide groove 2, continue to rotate the adjusting bolt 4 clockwise, so that the connecting unit 602 enters the slide groove 2, so that the slide groove 2 and the bead groove 604 form a columnar channel, and the connecting unit 602 moves in the columnar channel to complete the installation of the slider, so that the slider can move back and forth under the guidance of the slide groove 2, and after the slider is connected to the slide rail, the slider and the slide rail are only connected through the connecting unit 602, thereby greatly reducing the contact surface between the slider and the slide rail, and no sliding friction is generated. Only relying on the rolling friction of the connecting unit 602, the slider can not be separated from the slide rail and can move stably and smoothly, thereby reducing friction while reducing the noise generated by friction.

[0069] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
