Abstract
Description
Technical Field
[0001] This application relates to the field of linear guide module technology, and in particular to an intelligent device with an integrated side rail module. Background Technology
[0002] A linear guide module is a high-degree-of-freedom positioning module composed of three sets of orthogonally arranged linear guides, sliders, drive units, and rigid support structures. Existing linear guide modules employ a split-type structure design, consisting of two independent pre-fabricated steel guides assembled with aluminum profiles machined to a reference surface. The drive unit typically uses a servo motor to drive a ball screw, which in turn drives the nut to move axially along the screw, causing the slider to move along the guide.
[0003] However, traditional linear guide modules rely on manual assembly, which is prone to errors in assembly accuracy. The uncontrollability of assembly accuracy and the cumulative effect of accuracy errors ultimately lead to increased assembly costs and uncontrollable cumulative assembly errors. This makes it difficult to guarantee the overall assembly accuracy of the module and results in poor stability, leading to a decrease in subsequent processing accuracy. Furthermore, linear guide modules have weak vibration resistance and insufficient ability to absorb lateral torque. Under dynamic loads or complex stress conditions, they are prone to deformation or instability, affecting performance and narrowing their application range. Summary of the Invention
[0004] This application proposes an intelligent device with an integrated side rail module, which has the advantages of improving accuracy, reducing production costs and improving the overall accuracy of the module, in order to solve the problems of accuracy error caused by manual assembly of existing linear guide rail modules, as well as low assembly efficiency and high cost.
[0005] To achieve the above objectives, this application adopts the following technical solution: an intelligent device with an integrated side rail module, comprising a base and several sliders, wherein longitudinal slides are fixedly installed on both sides of the top of the base, a longitudinal moving seat is movably arranged on the top of the longitudinal slide, a movable seat is fixedly connected to one side of the longitudinal moving seat, a vertical slide is fixedly installed on the side of the two movable seats that are close to each other, a vertical moving seat is movably arranged on one side of the vertical slide, a lifting seat is fixedly connected between the two vertical moving seats, and a transverse slide is fixedly installed on both sides of the front of the lifting seat;
[0006] The longitudinal slide, vertical slide, and transverse slide all include guide rails and steel seats, and the guide rails and steel seats are integrally formed. The slider is provided with an oil supply mechanism, which is used to replenish the lubricating oil in the slider and can draw the lubricating oil at the bottom of the slider back to the top of the slider.
[0007] Furthermore, the guide rails corresponding to the longitudinal slide, vertical slide, and transverse slide are of different heights.
[0008] Furthermore, the oil supply mechanism includes two moving blocks, which are slidably connected to the slider. An oil inlet is fixedly connected to one side of the slider, and an oil storage chamber is opened on one side inside the slider. An oil replenishment hole is opened at the bottom of the inner wall of the oil storage chamber, and a first-way valve is fixedly installed at the bottom of the oil replenishment hole. Balance springs are fixedly connected to both sides of the slider.
[0009] Furthermore, a reflux hole is provided on one side of the slider, and a No. 3 one-way valve is fixedly installed on one side of the reflux hole. Several oil injection holes are provided on one side of the slider, and a No. 2 one-way valve is fixedly installed on one side of two corresponding oil injection holes. The position of the reflux hole is adapted to the arrangement posture of the corresponding slider. The reflux hole and the oil injection holes are located on both sides of the slider.
[0010] Furthermore, the first one-way valve is used for fluid to enter the slider in one direction through the oil replenishment hole, the second one-way valve is used for fluid to enter the ball raceway in one direction through the oil injection hole, and the third one-way valve is used for fluid to enter the cavity between the moving block and the slider in one direction through the return hole.
[0011] Furthermore, the number of reflux holes and oil replenishment holes are adapted to the number of moving blocks. A first sealing plate for sealing the reflux holes is fixedly connected to one side of the moving block. A through groove corresponding to the position of the reflux hole is opened on the side of the first sealing plate near the moving block. A second sealing plate is fixedly connected to one side of the moving block corresponding to the longitudinal slide. The axial length of the second sealing plate is adapted to the axial length of the through groove.
[0012] Furthermore, a connection hole is provided on one side of the inner wall of the oil storage chamber, and a No. 4 one-way valve is fixedly installed at one end of the connection hole. The No. 4 one-way valve is used for fluid to enter the oil storage chamber in one direction through the connection hole.
[0013] Furthermore, a balance hole is provided in the middle of the slider, and a balance block is slidably sleeved in the middle of the slider. The position of the balance block corresponds to the position of the balance hole, and a return spring is fixedly connected to the bottom of the balance block.
[0014] Furthermore, the base has several connecting plates on its top, and several electromagnets are installed on the top of the connecting plates.

This improves the overall accuracy and production efficiency of the module while reducing manufacturing costs. Furthermore, by utilizing a high-low drop sliding rail layout and a reinforced lateral support structure, it enhances the module's vibration resistance and lateral moment bearing capacity, consolidating the operational accuracy of the side rail module and expanding the applicability of this intelligent device in diverse and demanding application scenarios.
[0018] 2. The intelligent device with an integrated side rail module provided in this application draws the lubricant accumulated at the bottom of the slider due to gravity into a side cavity by moving the moving block relative to the slider during the slider movement. The lubricant is replenished through the oil replenishment pipe, and the replenished lubricant and the returned lubricant are sprayed out from the top of the corresponding slider posture of the ball bearing raceway through the oil spray pipe, so that the lubricant can soak the top part of the lubrication rail. At the same time, the movement frequency of the moving block increases with the movement frequency of the side rail module, which improves the adaptability of the oil replenishment frequency and the slider movement distance, and further improves the service life and reliability of the intelligent device.

[0032] 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.
[0033] Example 1, as Figures 1-5 A smart device with an integrated side rail module includes a base 1 and several sliders 9. Longitudinal slides 2 are fixedly installed on both sides of the top of the base 1. A longitudinal moving seat 3 is movably arranged on the top of the longitudinal slide 2. A movable seat 4 is fixedly connected to one side of the longitudinal moving seat 3. The movable seats 4 corresponding to the two longitudinal slides 2 are located on both sides of the base 1. A vertical slide 5 is fixedly installed on the side of the two movable seats 4 that are close to each other. A vertical moving seat 6 is movably arranged on one side of the vertical slide 5. A lifting seat 7 is fixedly connected between the two vertical moving seats 6. A transverse slide 8 is fixedly installed on both sides of the front of the lifting seat 7. A connecting seat 10 is movably arranged on the front of the transverse slide 8. The connecting seat 10 is used for the installation and fixation of the processing head.
[0034] The longitudinal slide 2, vertical slide 5, and transverse slide 8 all include guide rails and steel seats. (See reference...) Figure 2The guide rails corresponding to the longitudinal slide 2 are arranged on both sides of the top of the steel base and on one side of the base body, and the guide rails on both sides have different heights. (See reference...) Figure 3 The guide rails corresponding to the vertical slide table 5 are arranged on both sides of the steel base, and the guide rails on both sides have different heights. (See reference...) Figure 4 The guide rails corresponding to the transverse slide table 8 are respectively arranged on the top, bottom, and top surface of the front of the steel base, and the top and bottom guide rails have different heights. The slider 9 is slidably connected to the corresponding slide rail by ball bearings. Each slide rail corresponds to at least one slider 9. The guide rail and the steel base are made as a single piece. The specific process is as follows:
[0035] S1: The steel billet is heated to about 1050℃~800℃, and then forged into a preliminary shape in multiple stages using forging equipment and forging fixtures to complete hot forging;
[0036] S2: The initial steel billet is annealed, shot blasted, and cold drawn repeatedly using a horizontal cold drawing machine and cold drawing mold to further shape it to the target size. Alternatively, the initial steel billet is milled to the target size using a gantry machining center and forming tools, with a form and position accuracy of ±0.05.
[0037] S3: Straighten the straightness of the cold-drawn steel billet to within 0.12mm;
[0038] S4: The mounting hole shape and position accuracy is ±0.05 when using a gantry machining center with forming tools.
[0039] S5: The cold-drawn steel billet is straightened a second time using a hydraulic straightening device to correct the billet's twist, so that the straightness is corrected to within 0.12 mm;
[0040] S6: The guide rail quenching surface is processed to the rated hardness using a medium frequency quenching machine. The quenching machine is driven by a servo and equipped with a rotating head to quench each guide rail one by one.
[0041] S7: The cold-drawn steel billet is straightened three times using a hydraulic straightening device to correct the twist of the billet, and the straightness is corrected to within 0.12m;
[0042] S8: Use a special slant grinding machine to dress the corresponding forming grinding wheels for each guide rail; grind the quenched surface of the guide rail with the corresponding forming grinding wheels, and then grind the screw or linear motor mounting surface after dressing the outer circle of the grinding wheel into a plane; the accuracy of each grinding surface is ±0.003.
[0043] By using an integrated slide table design, the risks and uncontrollability of precision errors caused by manual assembly of traditional split linear modules are solved. This improves precision and production efficiency while reducing production costs and enhancing the overall precision of the module. Furthermore, by utilizing the height difference between the slide rails and the lateral mounting structure, the vibration resistance and lateral torque absorption performance of the linear module are improved, further enhancing the precision of use and making this intelligent device suitable for more diverse application scenarios.
[0044] In the side rail module, the lubricating oil inside the slider 9 is set in different postures. Under the action of gravity, the lubricating oil inside the slider 9 tends to concentrate at the bottom in the vertical direction, resulting in insufficient lubrication between the ball bearings at the top of the slider 9 and the slide rail. This leads to uneven wear on the top and bottom parts of the guide rail and affects the service life of the guide rail.
[0045] Example 2, as Figures 1-11 Based on Embodiment 1, an oil inlet 11 is fixedly connected to one side of the slider 9, see reference. Figure 6 An oil reservoir 12 is provided on one side of the slider 9. An oil replenishment hole 13 is provided at the bottom of the inner wall of the oil reservoir 12. A one-way valve 14 is fixedly installed at the bottom of the oil replenishment hole 13. Two moving blocks 15 are slidably sleeved on one side of the slider 9. The number and position of the oil replenishment holes 13 are matched with the number and position of the moving blocks 15. The two moving blocks 15 are located on both sides of the corresponding slide rail, used to deliver lubricating oil between the corresponding balls. The moving blocks 15 can move axially relative to the slider 9, that is, the direction of movement of the moving blocks 15 is collinear with the direction of movement of the slider 9 along the slide rail. (See reference...) Figure 8 A return hole 22 is provided on one side of the slider 9.
[0046] The number and position of the return holes 22 are adapted to the number and position of the moving blocks 15. One end of the return hole 22 connects to the cavity between the slider 9 and the slide rail, and the other end of the return hole 22 connects to the cavity between the corresponding moving block 15 and the slider 9. A three-way valve 23 is fixedly installed on one side of the return hole 22. (See reference) Figure 9 One side of the slider 9 has an oil injection hole 20. Each moving block 15 corresponds to two oil injection holes 20, and the two oil injection holes 20 are interconnected. One end of each oil injection hole 20 is connected to the corresponding ball raceway. (See reference...) Figure 7 One end of the oil injection hole 20 is connected to the cavity between the moving block 15 and the slider 9.
[0047] A second check valve 21 is fixedly installed on one side of the two corresponding oil injection holes 20 connected together. A first check valve 14 allows fluid to flow unidirectionally through the oil replenishment hole 13 into one side cavity of the corresponding moving block 15. A second check valve 21 allows fluid in one side cavity of the moving block 15 to flow unidirectionally through the oil injection hole 20 into the cavity between the corresponding slider 9 and the slide rail. A third check valve 23 allows fluid to flow unidirectionally through the return hole 22 into the cavity between the moving block 15 and the slider 9. Balance springs 19 are fixedly connected to both sides of the slider 9. The two balance springs 19 are used to push the moving block... Block 15 remains in its original position. A first sealing plate 16 for sealing the return hole 22 is fixedly connected to one side of the movable block 15. The first sealing plate 16 has a through groove 17 corresponding to the position of the return hole 22 on the side near the movable block 15. The position of the return hole 22 is adapted to the arrangement posture of the corresponding slider 9. The end of the return hole 22 near the inner side of the slider 9 is located at the bottom of the slider 9. When the slider 9 is installed horizontally, laterally, or vertically, one end of the return hole 22 can contact the lubricant accumulated on the inner side of the slider 9 under the action of gravity. (See reference...) Figure 8 The return hole 22 and the oil injection hole 20 are located on both sides of the slider 9, so that the lubricating fluid of the water flow is sprayed out from the ball raceway at the top of the slider 9 in its current position. The starting pressure of the first check valve 14 is greater than that of the third check valve 23.
[0048] Lubricating oil is pre-sent into the oil storage chamber 12 through the oil spray hole 20. During the use of the side rail module, the slider 9 moves along the slide rail, and the moving block 15 moves with the slider 9 through the balance spring 19. When the speed of the slider 9 changes, the moving block 15 will move relative to the slider 9 due to inertia. The movement of the moving block 15 drives the first sealing plate 16 to move relative to the return hole 22. The movement of the moving block 15 draws the lubricating oil accumulated on the inside of the slider 9 under the action of gravity back through the return hole 22. The lubricating oil enters the cavity between the moving block 15 and the slider 9 through the return hole 22 and the through groove 17. When the moving block 15 resets, the moving block 15 sprays the lubricating oil in the cavity out of the top ball raceway of the slider 9 through the oil spray hole 20, thereby completing the top and bottom circulation of the lubricating oil on the inside of the slider 9, ensuring that the top part of the slide rail is wetted with lubricating oil, ensuring the lubrication effect of the slide rail, and further improving the service life of the slide rail.
[0049] A second sealing plate 18 is fixedly connected to one side of the moving block 15 corresponding to the longitudinal slide table 2. The axial length of the second sealing plate 18 is matched with the axial length of the through groove 17. (See reference...) Figure 10A connection hole 29 is provided on one side of the inner wall of the oil storage chamber 12. A four-way valve 30 is fixedly installed at one end of the connection hole 29. The four-way valve 30 is used for fluid to enter the oil storage chamber 12 through the connection hole 29 in one direction. A balance hole 24 is provided in the middle of the slider 9. A balance block 25 is slidably sleeved in the middle of the slider 9. The position of the balance block 25 corresponds to the position of the balance hole 24. A return spring 26 is fixedly connected to the bottom of the balance block 25. The balance block 25 cooperates with the return spring 26 to balance the pressure inside the slider 9. The connection hole 29 is used to balance the pressure inside the oil storage chamber 12. Several connecting plates 27 are provided on the top of the base 1. Several electromagnets 28 are provided on the top of the connecting plates 27. A magnetic block is fixedly installed inside the moving block 15. The force between the electromagnet 28 and the magnetic block is an attraction force.
[0050] During the movement of the moving block 15 relative to the slider 9, the moving block 15 drives the first sealing plate 16 to move, so that the through groove 17 moves a rated distance and moves away from the corresponding position of the return hole 22. The first sealing plate 16 closes the return hole 22. At this time, the second sealing plate 18 moves away from the corresponding position of the oil replenishment hole 13 and opens the oil replenishment hole 13, so that the moving block 15 draws out part of the lubricant from the oil storage chamber 12 through the oil replenishment hole 13 for replenishment. During the reset, the replenished lubricant and the returned lubricant are filled into the inside of the slider 9. The more frequently the moving side rail module is used, the greater the frequency of slider 9 movement and the more times the lubricant is replenished, thus adapting to the use environment of the side rail module.
[0051] When the slider 9 corresponding to the longitudinal slide 2 is in a low-speed movement state, and the slider 9 moves to one side of the longitudinal slide 2 of the guide rail, the electromagnet 28 is activated, attracting the corresponding magnetic block to drive the moving block 15 to move against the elastic force of the balance spring 19, thereby adjusting the horizontal movement of the moving block 15, controlling the circulation of lubricating oil at the top and bottom and replenishing it, further improving the service life of the side guide rail module and extending the maintenance cycle of the intelligent device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
