Description

Technical Field

[0001] This invention relates to the field of hydrostatic guide rail technology, specifically to a hydrostatic guide rail assembly and its operation method that integrates horizontal adjustment and locking functions. Background Technology

[0002] Hydrostatic components typically refer to oil supply and throttling bearing units used in applications such as hydrostatic guideways and hydrostatic bearings. They use an external hydraulic source to deliver pressurized oil through oil channels and throttling structures to the bearing surface, forming a hydrostatic oil film with a certain thickness and pressure distribution. This allows the relatively moving guide pair to achieve bearing and guidance under the support of the oil film, thereby significantly reducing friction and wear, suppressing creep, and improving motion stability and positioning accuracy. It can also improve rigidity and vibration resistance, making it suitable for high-precision machine tools and heavy-duty low-speed scenarios.

[0003] Chinese patent document (publication number: CN116944898B) discloses a hydrostatic guide rail with locking function, including a base and a slide. The guide rail is mounted on the base, and a slider is mounted on the side of the slide facing the base. The slide is slidably connected to the guide rail via the slider. The slide has oil inlet holes, including a first oil inlet hole and a second oil inlet hole. The slider has oil outlet holes, including a first oil outlet hole and a second oil outlet hole. The first oil outlet hole and the second oil outlet hole are respectively located on opposite sides of the slider, so that the slide has a moving state and a locked state. In the moving state, both the first oil inlet hole and the second oil inlet hole are open, and the slider and the base and / or guide rail are separated by hydraulic oil to achieve a balanced state. In the locked state, one of the first oil inlet hole and the second oil inlet hole is open, and the other is closed, so that the hydraulic oil pushes the slider to move to one side and abuts against the base and / or guide rail, so that the slide is locked in a predetermined position. The technical solution of the present invention maintains the high surface accuracy of the hydrostatic guide rail.

[0004] In existing technologies, the normal operation of hydrostatic components requires stable oil film support. However, once the power is cut off or the hydraulic pressure drops due to abnormality, the oil film's load-bearing capacity drops sharply, making the slider prone to inertial slippage and impact. Traditional locking and cutting-in single-sided force braking can easily lead to uneven force on the slider, causing displacement or vibration. In severe cases, it can affect the matching accuracy between the slider and the guide rail. Furthermore, the assembly locking structure is prone to interference, and multiple locking units are difficult to position synchronously, resulting in cumbersome assembly calibration, easy jamming, and affecting repeatability accuracy. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hydrostatic guide rail assembly and operating method that integrates horizontal adjustment and locking functions. The assembly of this invention uses a slide rail and a slider as the load-bearing base, and integrates the leveling mechanism, the self-triggered locking mechanism, and the oil supply system into a coordinated design. This allows the slider to achieve low-friction and stable sliding under the condition of forming a balanced oil film. At the same time, it automatically switches to reliable locking when the pressure supply is abnormal and uses progressive damping to dissipate energy and reduce impact. This balances assembly leveling accuracy, operational stability, and pressure loss safety, while also improving the lifespan of the guide rail system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A hydrostatic guide rail assembly integrating horizontal adjustment and locking functions includes a slide rail and a slider mounted on the bottom of a slide plate. The slider slides in the slide rail, which has a T-shaped sliding channel. Two locking channels are opened on opposite sides of the sliding channel, and the locking channels are connected to the sliding channel. Oil outlet holes are symmetrically opened on the outer circumferential surface of the slider that are in contact with the sliding channel. The oil outlet holes extend through internal oil passages to external oil holes of the slide plate, which are connected to an external pressure oil source. Locking blocks extending outward are symmetrically arranged on both sides of the slider. The locking blocks are connected to the slider through a telescopic mechanism and slide in the locking channel. Locking components are provided on the opposite surfaces of the locking blocks and locking channels. The telescopic mechanism triggers the locking components to limit the slider when it loses oil pressure support. A decoupling component is provided on one side of the locking block. During installation or disassembly, the decoupling component keeps the locking components in a separated state for quick assembly and disassembly.

[0007] Preferably, the slider includes a slider body and two sets of slider end platforms, which are symmetrically arranged at the beginning and end of the slider body. Two symmetrical accommodating cavities are formed on both sides of the slider body. A third core oil channel and a fourth core oil channel are opened in the middle of the slider body. The third core oil channel and the fourth core oil channel are respectively opened to form two conical holes and connect to the accommodating cavities on both sides. The other ends of the third core oil channel and the fourth core oil channel are respectively connected to external oil holes through oil channels. A through-hole is opened on the side of the accommodating cavity. A detachable sealing plate is installed in the through-hole. The sealing plates on both sides are symmetrically opened with third oil outlets. Oil from the third oil outlets on both sides forms an oil film between the oil and the adjacent slide rail sidewall. A telescopic mechanism is slidably arranged inside the accommodating cavity.

[0008] Preferably, the telescopic mechanism includes a crossbar and a longitudinal bar that are fixedly connected to each other, forming a cross-shaped structure; guide grooves are symmetrically arranged on both sides of the accommodating cavity, and the two sets of guide grooves are arranged along the length of the slide rail, with both ends of the crossbar slidingly engaged in the guide grooves; a conical plug is fixedly installed at one end of the longitudinal bar, and the conical plug slides through the conical hole, while the other end of the longitudinal bar slides through the sealing plate and extends into the locking channel, with a locking block installed at the end of the longitudinal bar; a wedge rod is installed on the side of the locking block near the sealing plate, and a stop plate is fixedly installed on the side opposite to the wedge rod in the locking channel, with the wedge rod and the stop plate cooperating to achieve locking; two sets of guide rods are symmetrically arranged on both sides of the longitudinal bar, with the guide rods passing through the sealing plate and screwed to the side wall of the accommodating cavity, the guide rods slidingly passing through the crossbar, and a return spring is slidably sleeved on the guide rod, with both ends of the return spring fixedly connected to the crossbar and the sealing plate respectively, the preload of the return spring pushing the conical plug into the conical hole to achieve oil passage sealing, and causing the wedge rod and the stop plate of the locking assembly to maintain a locked engagement.

[0009] Preferably, the end of the longitudinal rod near the locking block extends outward to form a tail rod, the locking block is slidably sleeved on the tail rod, and a decoupling component is provided at the tail rod. The decoupling component includes a cam, a fourth threaded hole is opened on the tail rod, a rotating shaft passes through the fourth threaded hole, the rotating shaft has an external thread corresponding to the fourth threaded hole and is screwed into the fourth threaded hole, cams are fixed on the rotating shafts on both sides of the tail rod respectively, the cams have arc-shaped guide grooves, and guide rods are fixed on the locking block corresponding to the two sets of cams respectively, the guide rods slidingly fitting in the arc-shaped guide grooves; on the cams An avoidance limiting unit and a locking limiting unit are provided between the locking block and the locking block. The avoidance limiting unit includes a first limiting hole and a limiting rod on the cam. The first limiting hole is located on the outer side of one end of the arc-shaped guide groove and is close to the end of the rotating shaft. A second limiting hole is provided on the locking block near the guide rod. The second limiting hole is located below the guide rod and close to the side of the cam. The first limiting hole and the second limiting hole overlap and are inserted by the limiting rod to prevent rotational misalignment. The end of the rotating shaft extends towards the slide rail opening and a screwing part is fixed at the end.

[0010] Preferably, the locking and limiting unit includes a third limiting hole, a fourth limiting hole, and a limiting rod. The third limiting hole is located on the outer side of one end of the arc-shaped guide groove of the cam and at the end away from the rotating shaft. The fourth limiting hole is opened on the locking block near the guide rod, and the fourth limiting hole is located above the guide rod and near the cam. The third limiting hole and the fourth limiting hole overlap and are limited by the insertion of the limiting rod to prevent the cam from rotating and causing misalignment. Two or more sets of sliders are provided on one side of the slide, and the rotating shaft is installed on the tail rod of each set of sliders. Adjacent rotating shafts are fixedly connected by a coupling. An avoidance limiting unit and a locking limiting unit are provided on a set of sliders adjacent to the end opening of the slide rail.

[0011] Preferably, the locking assembly includes a stop plate and a wedge rod; first protrusions are symmetrically formed on both sides of the sliding channel, and the first protrusions are arranged parallel to the bottom plate of the sliding channel. Two second protrusions are formed at the connection between the locking channel and the sliding channel. The two second protrusions are respectively located on the first protrusion and the bottom plate of the sliding channel. The opposing surfaces of the two sets of second protrusions are spaced apart to form a sliding channel. A stop plate is fixed on each of the two sets of second protrusions inside the locking channel. The stop plate is toothed. A wedge rod is fixed on the side of the locking block near the stop plate. The main body of the wedge rod is plate-shaped. The two sides of the end of the wedge rod are set as constricted bevels. When the wedge rod initially contacts the stop plate, the constricted bevels and the teeth of the stop plate form sliding friction and generate a wedge action, which drives the longitudinal rod away from the cone hole to generate displacement, thereby compressing the return spring and consuming the kinetic energy of the sliding slider until it is locked in a stationary state. When stationary, the plate-shaped main body of the wedge rod extends into the tooth gap of the stop plate to form a lock.

[0012] Preferably, a first core oil channel and a second core oil channel are formed on the top of the slider end platform. The first core oil channel and the second core oil channel are connected to the external oil hole of the slide plate through the oil channel. A first main oil channel is formed in the upper part of the slider end platform. The first core oil channel is connected to the first main oil channel. The two ends of the first main oil channel extend toward the two ends of the slider end platform respectively. An extended first branch oil channel is formed at each end of the first main oil channel. Multiple first oil outlets are formed through the sidewalls of the first branch oil channels toward the top of the slider end platform. The opening direction of the first oil outlets is perpendicular to the first boss, so as to facilitate the formation of an oil film at the first boss.

[0013] Preferably, a second main oil channel is built into the bottom of the slider end platform, and the second core oil channel is connected to the second main oil channel. The two ends of the second main oil channel extend toward the two ends of the slider end platform, and the two ends of the second main oil channel are respectively opened into extended second branch oil channels. The sidewalls of the second branch oil channels extend toward the bottom of the slider end platform and open into multiple second oil outlets. The opening direction of the second oil outlets is perpendicular to the bottom plate of the sliding channel, so as to facilitate the formation of an oil film at the bottom plate of the sliding channel and balance it with the oil film formed at the first protrusion, so that the slider is in a low-friction sliding state.

[0014] Preferably, a top plate is provided on the top of the slide, and a leveling mechanism is installed between the slide and the top plate. The leveling mechanism includes a double-threaded sleeve, a threaded head, and three sets of third threaded holes opened on the top of the slide. The three sets of third threaded holes are evenly distributed on the outer edge of the slide. The third threaded holes are blind holes. The double-threaded sleeve has external threads on the outside and internal threads on the inside. The bottom of the threaded head has a reduced-diameter threaded section and is screwed into the third threaded hole. The threaded head is located on the top of the slide and has an inner opening for accommodating adjustment tools. The top plate has first threaded holes corresponding to the three sets of threaded heads. Double-threaded sleeves are screwed into the first threaded holes respectively. The double-threaded sleeves are threaded onto the outer circumference of the threaded head. The top of the double-threaded sleeve has an operating port for inserting tools and adjusting their rotation.

[0015] Preferably, the operation method of the hydrostatic guide rail assembly with integrated leveling and locking functions includes the following steps: S1. Before assembly, rotate the shaft to retract the locking block and allow the wedge rod to avoid the stop plate. Insert the limit rod into the first limit hole and keep it in the second limit hole to avoid it. After assembly, pull it out. Rotate the shaft in the opposite direction to allow the wedge rod to enter the stop plate and insert the limit rod into the third limit hole and the fourth limit hole to keep it in the working position. Rotate the double threaded sleeve to adjust the height of the top plate relative to the slide plate by cooperating with the first threaded hole and the threaded head. S2. The external oil hole supplies oil to form an oil film in the sliding channel and the force surface, which makes the slider slide. The oil pressure causes the conical plug to exit the conical hole and the locking block to retract through the longitudinal rod. The wedge rod and the stop plate are not engaged. S3. When the supply pressure decreases, the conical plug retracts from the conical hole under the action of the return spring and drives the longitudinal rod to move, which in turn moves the locking block and the wedge rod toward the stop plate and triggers locking. The constricted inclined surface of the wedge rod slides into or out of the stop plate teeth and compresses the return spring to gradually dissipate energy. The conical plug and the hydraulic oil squeeze the micro-motion to form damping, which reduces impact wear and improves triggering stability. S4. After the wedge rod is in place, it is inserted into the toothed slot of the stop plate and engages with the limit position to reliably lock the slider relative to the slide rail. S5. During disassembly and maintenance, reverse the operation of S1 to remove the wedge rod from the stop plate and eliminate interference before removing the slider.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The components of this invention use slide rails and sliders as the load-bearing base, and integrate the leveling mechanism, self-trigger locking mechanism and oil supply system into a coordinated design. This allows the slider to achieve low-friction and stable sliding under the condition of forming a balanced oil film. At the same time, it automatically switches to the locking state when the pressure supply is abnormal. The braking is set symmetrically on both sides to avoid slider deviation or jitter, and energy is dissipated and impact is reduced by progressive damping. This balances the assembly leveling accuracy, running stability and pressure loss safety, and improves the life of the guide rail system.

[0017] 2. When the power supply pressure drops due to a power outage or hydraulic anomaly, the oil pressure holding force in the third and fourth core oil passages of this invention decreases, causing the conical plug to retract under the action of the return spring. This drives the longitudinal rod to output displacement, which in turn drives the locking block to push the wedge rod into the locking channel to complete self-trigger locking. More notably, the constricted bevel at the end of the wedge rod slides into the stop plate teeth first, allowing the locking contact to be established gradually from light to heavy. The compression of the return spring and the micro-movement of the conical plug and the hydraulic oil in the conical hole form a composite damping, thereby converting inertial slippage into controllable slow-release deceleration without the need for additional independent damping components, significantly reducing tooth surface impact wear. Finally, the plate-shaped body of the wedge rod inserts into the tooth gap of the stop plate to form a mechanical limit with tooth bearing, making the anti-retraction more stable and improving the locking reliability and trigger controllability under pressure loss conditions.

[0018] 3. In the assembly and maintenance stages, the components of this invention utilize a rotating shaft to drive the cam and, in conjunction with an arc-shaped guide rod, achieve controllable traction of the locking block. This allows multiple coaxial wedge rods to quickly disengage from the stop plate and enter an avoidance state, eliminating assembly interference. Simultaneously, the positioning cooperation between the limiting rod and the limiting hole ensures reliable holding of the cam between the avoidance position and the working position. It also provides consistent limiting for multiple coaxially arranged locking blocks and wedge rods, significantly reducing the difficulty of manual calibration and improving assembly efficiency. Furthermore, it avoids the risk of jamming caused by asynchronous locking units and enhances the consistency and repeatability of the entire machine.

[0019] 4. Under normal operating conditions, the components of this invention deliver hydraulic oil to the oil passage through the external oil hole, thereby establishing a stable and balanced oil film on the outer periphery of the slider, which significantly reduces friction and creep and improves positioning stability. More importantly, the oil pressure exerts a controlled effect on the conical plug and conical hole and maintains the locking block's retraction through the longitudinal rod, keeping the wedge rod and the stop plate in a non-engaging state for a long time. This avoids additional disturbances to the sliding quality caused by the locking mechanism from the source and improves the consistency of operation under high-speed and low-speed conditions.

Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

[0022] Contents not described in detail in this specification are prior art known to those skilled in the art.

Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Figures 1-12 As shown, a hydrostatic guide rail assembly integrating horizontal adjustment and locking functions includes a slide rail 11 and a slider 12 mounted on the bottom end of a slide plate 13. The slider 12 slides within the slide rail 11, and the slide rail 11 has a T-shaped section. The sliding channel 21 has a sliding structure with two locking channels 24 on opposite sides, which are connected to the sliding channel 21. Oil outlet holes are symmetrically provided on the outer circumference of the slider 12 in contact with the sliding channel 21. These oil outlet holes extend through internal oil passages to external oil holes 63 on the slide plate 13, which are connected to an external pressure oil source. Locking blocks 34 extending outwards are symmetrically provided on both sides of the slider 12. The locking blocks 34 are connected to the slider 12 via a telescopic mechanism, and slide within the locking channel 24. Locking components are provided on the opposite surfaces of the locking blocks 34 and the locking channel 24. The telescopic mechanism triggers the locking components to limit the slider 12 when it loses its hydraulic support. A decoupling component is provided on one side of the locking blocks 34. During installation or disassembly, the decoupling component separates the locking components for quick assembly and disassembly.

[0024] The components of this invention use slide rail 11 and slider 12 as the supporting base, and integrate the leveling mechanism, self-trigger locking mechanism and oil supply system into a coordinated design. This allows slider 12 to achieve low-friction and stable sliding under the condition of forming a balanced oil film. At the same time, it automatically switches to reliable locking when the pressure supply is abnormal and uses progressive damping to dissipate energy and reduce impact. This balances the assembly leveling accuracy, operational stability and pressure loss safety, and improves the life of the guide rail system.

[0025] Furthermore, the slider 12 includes a slider body 27 and two sets of slider end platforms 26. The two sets of slider end platforms 26 are symmetrically arranged at the beginning and end of the slider body 27, and two symmetrical accommodating cavities 28 are formed on both sides of the slider body 27. A third core oil channel 59 and a fourth core oil channel 60 are opened in the middle of the slider body 27. The third core oil channel 59 and the fourth core oil channel 60 respectively pass through to form two conical holes 31 and connect to the accommodating cavities 28 on both sides. The other ends of the third core oil channel 59 and the fourth core oil channel 60 are respectively connected to the external oil hole 63 through oil channels. A through-hole is opened on the side of the accommodating cavity 28. A detachable sealing plate 29 is installed in the through-hole. The sealing plates 29 on both sides are symmetrically opened with third oil outlets 65. Oil from the third oil outlets 65 on both sides forms an oil film between the oil and the side wall of the adjacent slide rail 11. A telescopic mechanism is slidably arranged inside the accommodating cavity 28.

[0026] It should be noted that the third core oil channel 59 extends into the interior of the slider body 27 and then changes direction vertically after passing through the third main oil channel 61 to form a conical hole 31 on one side; the fourth core oil channel 60 extends into the interior of the slider body 27 and then changes direction vertically after passing through the fourth main oil channel 62 to form a conical hole 31 on the other side.

[0027] The slider 12 is composed of a slider body 27 and symmetrical slider end platforms 26, and symmetrical accommodating cavities 28 are provided on both sides to integrate oil supply and functional arrangement: the third core oil passage 59 and the fourth core oil passage 60 pass through to form a conical hole 31 and are respectively connected to the accommodating cavity 28, and are connected to the external oil port 63 through the oil passage to introduce and distribute external hydraulic oil; the detachable sealing plate 29 on the side of the accommodating cavity 28 is provided with a third oil outlet 65, so that the oil outlet forms an oil film on the side wall of the slide rail 11, providing lateral static pressure support and guidance, reducing friction and improving operating stability; the accommodating cavity 28 also provides sliding installation space for the telescopic mechanism, and the sealing plate 29 facilitates assembly and maintenance.

[0028] Furthermore, the telescopic mechanism includes a crossbar 32 and a longitudinal bar 30 fixedly connected to each other, forming a cross-shaped structure; guide grooves 37 are symmetrically arranged on both sides of the accommodating cavity 28, with two sets of guide grooves 37 arranged along the length of the slide rail 11, and the two ends of the crossbar 32 slidingly engaged in the guide grooves 37; a conical plug 36 is fixedly installed at one end of the longitudinal bar 30, and the conical plug 36 slides through the conical hole 31; the other end of the longitudinal bar 30 slides through the sealing plate 29 and extends into the locking channel 24, and a locking block 34 is provided at the end of the longitudinal bar 30; a wedge rod 44 is provided on the side of the locking block 34 near the sealing plate 29, and the locking channel 24 is engaged with... A stop plate 25 is fixedly installed on the opposite side of the wedge rod 44. The wedge rod 44 and the stop plate 25 cooperate to achieve locking. Two sets of guide rods 33 are symmetrically arranged on both sides of the longitudinal rod 30. The guide rods 33 pass through the sealing plate 29 and are screwed to the side wall of the accommodating cavity 28. The guide rods 33 slide through the through hole 40 of the cross rod 32. A return spring 38 is slidably sleeved on the guide rod 33. The two ends of the return spring 38 are fixedly connected to the cross rod 32 and the sealing plate 29 respectively. The preload of the return spring 38 pushes the conical plug 36 into the conical hole 31 to achieve oil passage sealing and cause the wedge rod 44 to maintain a locked fit with the stop plate 25 of the locking assembly. When the hydraulic circuit is started, pressurized oil enters through the third core oil passage 59 and the fourth core oil passage 60, and reaches the corresponding conical hole 31 through the first branch oil passage 61 and the second branch oil passage 62 respectively. The hydraulic oil pressure pushes the conical plug 36 backward and causes the oil to enter the two side accommodating cavities 28, and then exits through the corresponding third oil outlet 65, forming an oil film symmetrically on both sides of the slider 12 and the slide rail 11. At the same time, the conical plug 36 drives the longitudinal rod 30 to move and compress the return spring 38, causing the locking block 34 and the wedge rod 44 to move away from each other. The stop plate 25 releases the locking contact, establishing the basic conditions for the free sliding of the slider 12; conversely, when the oil supply of the third core oil passage 59 and the fourth core oil passage 60 decreases or the pressure decreases, the return spring 38 releases elastic potential energy to push the longitudinal rod 30 back towards the conical hole 31, causing the wedge rod 44 to approach and press against the stop plate 25 to form deceleration and locking, thereby limiting the relative movement during the stage when the oil film weakens or disappears, and avoiding dry friction between the slider 12 and the slide rail 11, which would damage the precision contact surface and affect the accuracy.

[0029] Furthermore, the end of the longitudinal rod 30 near the locking block 34 extends outward to form a tail rod 46. The locking block 34 is slidably sleeved on the tail rod 46. A decoupling assembly is provided at the tail rod 46. The decoupling assembly includes a cam 35. A fourth threaded hole 47 is opened on the tail rod 46. A rotating shaft 45 passes through the fourth threaded hole 47. An external thread 48 is provided on the rotating shaft 45 corresponding to the fourth threaded hole 47 and screwed into the fourth threaded hole 47. Cams 35 are fixed on the rotating shafts 45 on both sides of the tail rod 46, and the cams 35 have arc-shaped guide grooves 42. Guide rods 41 are fixed on the locking block 34 corresponding to the two sets of cams 35. The guide rods 41 slide in the arc-shaped guide grooves. Inside 42; an avoidance limiting unit and a locking limiting unit are provided between the cam 35 and the locking block 34. The avoidance limiting unit includes a first limiting hole 43 and a limiting rod 50 opened on the cam 35. The first limiting hole 43 is located outside one end of the arc-shaped guide groove 42 and is located near the end of the rotating shaft 45. A second limiting hole 49 is opened on the locking block 34 near the guide rod 41. The second limiting hole 49 is located below the guide rod 41 and near the side of the cam 35. The first limiting hole 43 and the second limiting hole 49 are inserted and limited by the limiting rod 50 to avoid rotational misalignment. The end of the rotating shaft 45 extends towards the opening of the slide rail 11 and a screwing part is fixed at the end. When there is no hydraulic oil pressure, the preload of the return spring 38 keeps the conical plug 36 inside the conical hole 31, while the wedge rod 44 extends into the corresponding position of the stop plate 25. The slider 12 and the slide rail 11 are in a locked or occupied state. When assembled, they are difficult to separate, and when not assembled, the wedge rod 44 is difficult to insert to complete the assembly because it occupies the stop plate 25. To solve the above-mentioned disassembly and assembly interference problem, a decoupling component is set at the tail rod 46, and the locking block 34 is a structure that slides on the longitudinal rod 30 and the tail rod 46, so that it can be "pushed closer or pulled away" relative to the stop plate 25 in the axial direction. During disassembly and assembly, the rotating screwing part drives the rotating shaft 45 to rotate, and the cam 35 rotates accordingly. Due to the eccentric setting of the cam 35, the arc-shaped guide groove 42 on the cam 35 guides the guide rod 41, causing the guide rod 41 to move along the arc-shaped guide groove 42 and move as a whole towards the rotating shaft 45. This causes the locking block 34, which is fixed to it, to move along the axis of the longitudinal rod 30 and the tail rod 46, so that the wedge rod 44 moves away from the stop plate 25, thereby releasing the locking contact and eliminating assembly interference, so that the slider 12 and the slide rail 11 are in a separable or insertable state; when the locking block 34 moves to the position where the wedge rod 44 and the stop plate 25 are completely separated, the limit rod 50 is inserted into the first limit hole 43 and the second limit hole 49 to limit and maintain the posture of the cam 35 and the position of the locking block 34, preventing the rotating shaft 45 from rotating or returning to its original position, and ensuring continuous decoupling during disassembly and assembly; after the assembly or disassembly of the slide rail 11 and the slider 12 is completed, the limit rod 50 is pulled out to release the limit, the rotating screw is rotated to drive the rotating shaft 45 to rotate and reset, the decoupling component exits the holding state, and the mechanism can be restored to the automatic unlocking and automatic locking working logic under normal oil supply or pressure loss conditions; It should be noted that corresponding limiting holes are opened on the upper part of the cam 35 and the locking block 34. Similarly, the limiting rod is inserted to limit the locking block 34 and the stop plate 25 to be in the limited engagement position, so as to prevent the rotating shaft 45 and the cam 35 from rotating and prevent the phenomenon of backward sliding, thus ensuring the stability of the structure.

[0030] The screwing part can be a disc structure that is easy to screw on by hand, or it can be adapted to the size requirements and set as a corresponding coupling port that can be adjusted by inserting a screwdriver.

[0031] Furthermore, the locking and limiting unit includes a third limiting hole, a fourth limiting hole, and a limiting rod 50. The third limiting hole is located on the outer side of one end of the arc-shaped guide groove 42 of the cam 35, and at the end away from the rotating shaft 45. The fourth limiting hole is opened on the locking block 34 near the guide rod 41, and the fourth limiting hole is located above the guide rod 41 and near the cam 35. The third limiting hole and the fourth limiting hole are limited by the insertion and cooperation of the limiting rod 50 to prevent the cam 35 from rotating and causing misalignment. Two or more sets of sliders 12 are provided on one side of the slide plate 13. The rotating shaft 45 is installed on the tail rod 46 of each set of sliders 12, and adjacent rotating shafts 45 are fixedly connected by a coupling. An avoidance limiting unit and a locking limiting unit are provided on a set of sliders 12 that are close to the end opening of the slide rail 11. The avoidance limit unit is used to mechanically retain the locking block 34, which has been driven to the position where "wedge rod 44 is away from stop plate 25" in the decoupled and assembly conditions, to prevent it from accidentally returning to the stop plate 25 again under the action of no oil pressure and return spring 38, and to avoid disassembly and assembly interference and collision. The locking and limiting unit is used to prevent the wedge rod 44 of the locking block 34 from accidentally separating from the stop plate 25 when the oil is stopped or when mechanical locking is required during normal operation of the device. Specifically, the locking and limiting unit mechanically holds the locking block 34, which has been driven to the position where the wedge rod 44 is close to and locks with the stop plate 25, to prevent accidental retraction that could lead to locking separation and to avoid the risk of relative slippage when the oil film is insufficient. When two or more sets of sliders 12 are arranged on one side of the slide plate 13, the rotating shafts 45 on each set of tail rods 46 are fixedly connected by couplings, so that each set of cams 35 rotates synchronously and each set of locking blocks 34 moves synchronously; only the set of sliders 12 with the opening at the end of the slide rail 11 is arranged with the avoidance limit unit and the locking limit unit, so that all sets can be uniformly limited by the coupling transmission, which is convenient for single-point operation and saves installation structure and space.

[0032] Furthermore, the locking assembly includes a stop plate 25 and a wedge rod 44; first protrusions 22 are symmetrically formed on both sides of the sliding channel 21, and the first protrusions 22 are arranged parallel to the bottom plate of the sliding channel 21; two second protrusions 23 are formed at the connection between the locking channel 24 and the sliding channel 21, and the two second protrusions 23 are respectively located on the first protrusions 22 and the bottom plate of the sliding channel 21; the opposing surfaces of the two sets of second protrusions 23 are spaced apart to form a sliding channel; a stop plate 25 is fixed on each of the two sets of second protrusions 23 inside the locking channel 24, and the stop plate 25 is toothed. The locking block 34 is arranged in a plate-like shape. A wedge rod 44 is fixed on the side of the locking block 34 near the stop plate 25. The main body of the wedge rod 44 is plate-shaped, and the two sides of the end of the wedge rod 44 are set as constricted bevels. When the wedge rod 44 initially contacts the stop plate 25, the constricted bevels and the teeth of the stop plate 25 form sliding friction and generate a wedge action, which drives the longitudinal rod 30 away from the tapered hole 31 to generate displacement, thereby compressing the return spring 38 to consume the sliding kinetic energy of the slider 12 until it is locked in a stationary state. When stationary, the plate-shaped main body of the wedge rod 44 extends into the tooth gap of the stop plate 25 to form a lock. The wedge rod 44 can be configured as a single unit or two sets symmetrically arranged. The contact point between the constricted bevel of the wedge rod 44 and the tooth of the stop plate 25 uses a small rounded corner or chamfer to reduce the risk of chipping. It should be noted that the wedge rod 44 is a replaceable sacrificial part to protect the stop plate 25. The stop plate 25 is hardened with 40Cr / 42CrMo after quenching and tempering, resulting in a tooth surface hardness of approximately HRC50. The wedge rod 44 can be made into a replaceable wear-resistant block or insert. The base material is quenched and tempered with 40Cr / 42CrMo (approximately HRC28–35), and a wear-resistant layer is welded onto the constricted bevel. Alternatively, a steel base material with an aluminum bronze insert can be used to create the constricted bevel to prevent seizing. Wear mainly occurs on the wedge rod 44; if damaged, the wedge rod 44 can be replaced. The stop plate 25 is not easily damaged by wear. The locking assembly serves to guide and limit movement, provide progressive contact energy dissipation, and lock the tooth gaps. The locking assembly works in conjunction with the telescopic mechanism, generating a damping effect through the combined action of the longitudinal rod 30, the conical hole 31, the conical plug 36, the return spring 38, and subsequent hydraulic oil. The stop plate 25 is fixed to two sets of second protrusions 23 inside the locking channel 24, forming toothed limiting surfaces on both sides of the channel, providing a symmetrical and repeatable engagement reference for the wedge rod 44. When the locking block 34 moves the wedge rod 44 closer to the stop plate 25, the constricted inclined surfaces on both sides of the wedge rod 44 first slide into contact with the teeth of the stop plate 25, generating a wedge-in effect. This pushes the longitudinal rod 30 to displace relative to the conical hole 31 and compresses the return spring 38, thereby buffering and dissipating the sliding energy of the slider 12, reducing impact, and preventing rigid jamming. When the relative motion decays to rest, the plate-like body of the wedge rod 44 inserts into the stop plate. The 25-tooth gap achieves locking, with the locking force borne by the tooth profile, resulting in more stable anti-retraction. On the other hand, the return spring 38 provides a springback return tendency while keeping the conical plug 36 pressed tightly within the conical hole 31, acting as a seal. Under the action of subsequent hydraulic oil, the hydraulic pressure pushes the conical plug 36 to generate displacement within the conical hole 31 and outputs driving force, thereby providing a power source for the movement of subsequent components. Furthermore, the conical plug 36, in contact with the hydraulic oil within the conical hole 31, can form a certain damping, suppressing the abrupt displacement and springback vibration of the longitudinal rod 30 and consuming kinetic energy, making the contact and disengagement process between the wedge rod 44 and the stop plate 25 smoother. At the same time, the wedge rod 44, in conjunction with the action, causes the conical plug 36 to produce reciprocating micro-movements. The combination of the above structures, without the need for additional independent damping components, reduces locking impact and tooth surface impact wear, and improves the stability and controllability of the hydraulic triggering action.

[0033] Furthermore, a first core oil channel 51 and a second core oil channel 52 are provided on the top of the slider end platform 26. The first core oil channel 51 and the second core oil channel 52 are connected to the external oil hole 63 of the slide plate 13 through the oil channel. A first main oil channel 53 is provided in the upper part of the slider end platform 26. The first core oil channel 51 is connected to the first main oil channel 53. The two ends of the first main oil channel 53 extend toward the two ends of the slider end platform 26 respectively. An extended first branch oil channel 54 is provided at the two ends of the first main oil channel 53. Multiple first oil outlets 55 are provided through the sidewalls of the first branch oil channels 54 toward the top of the slider end platform 26. The opening direction of the first oil outlets 55 is perpendicular to the first boss 22, so as to facilitate the formation of an oil film at the first boss 22.

[0034] Furthermore, a second main oil channel 56 is built into the bottom of the slider end platform 26. The second core oil channel 52 is connected to the second main oil channel 56. The two ends of the second main oil channel 56 extend toward the two ends of the slider end platform 26 respectively. The two ends of the second main oil channel 56 are respectively opened into extended second branch oil channels 57. The sidewalls of the second branch oil channels 57 extend toward the bottom end of the slider end platform 26 and open into multiple second oil outlets 58. The opening direction of the second oil outlets 58 is perpendicular to the bottom plate of the sliding channel 21, so as to facilitate the formation of an oil film at the bottom plate of the sliding channel 21 and balance it with the oil film formed at the first protrusion 22, so that the slider 12 is in a low-friction sliding state.

[0035] The oil supply and distribution structure guides the pressurized oil to the upper and lower bearing surfaces respectively, and establishes stable oil films at the upper boss and the bottom plate of the lower channel through a multi-point uniform oil supply method of main oil channel - branch oil channel - multiple oil outlets. From the perspective of oil film balance, the pressure fields of the upper and lower oil films counterbalance each other, which can suppress the pitching or overturning moment and local contact caused by eccentric load, reduce the fluctuation of oil film thickness and uneven pressure drop, thereby improving the bearing stiffness and motion stability, and keeping the whole body with low friction and smooth sliding.

[0036] Furthermore, the ends of the first core oil passage 51, the second core oil passage 52, the first main oil passage 53, the first branch oil passage 54, the second main oil passage 56, the second branch oil passage 57, the third core oil passage 59, and the fourth core oil passage 60 all have through-holes. The through-holes are formed when the oil passages are opened and are sealed by installing plugs 39 to avoid using a high-cost one-piece molding process.

[0037] It should be noted that the first core oil passage 51, the second core oil passage 52, the third core oil passage 59 and the fourth core oil passage 60 extend from the mounting through-holes on the slide plate 13 to form mounting holes 64.

[0038] Furthermore, a top plate 14 is provided on the top of the slide 13, and a leveling mechanism is installed between the slide 13 and the top plate 14. The leveling mechanism includes a double-threaded sleeve 17, a threaded head 18, and three sets of third threaded holes 19 opened on the top of the slide 13. The three sets of third threaded holes 19 are evenly distributed on the outer edge of the slide 13. The third threaded holes 19 are blind holes. The double-threaded sleeve 17 has external threads on the outside and internal threads on the inside. The bottom of the threaded head 18 has a reduced-diameter threaded section and is screwed into the third threaded hole 19. The threaded head 18 is located on the top of the slide 13. The threaded head 18 has an inner opening 20 for accommodating adjustment tools. The top plate 14 has first threaded holes 15 corresponding to the three sets of threaded heads 18. The double-threaded sleeve 17 is screwed into the first threaded hole 15. The double-threaded sleeve 17 is threaded onto the outer periphery of the threaded head 18. The top of the double-threaded sleeve 17 has an operating port for inserting tools and adjusting their rotation. During leveling, the adjusting tool is inserted into the inner opening 20 of the threaded head 18 to restrict the rotation of the threaded head 18. Then, the double-threaded sleeve 17 is screwed through the operating port at the top of the double-threaded sleeve 17 to convert the rotational motion into axial displacement, causing the double-threaded sleeve 17 to move in and out relative to the axial direction, thereby driving the top plate 14 to move up or down. The height of the three evenly distributed double-threaded sleeves 17 is finely adjusted at their corresponding positions, and the point-by-point correction is used to achieve the horizontal adjustment of the top plate 14 and maintain the leveling state. Among them, the square screwdriver is installed in the inner opening 20, and the screwing workpiece inserted into the operating port of the threaded sleeve 17 needs to be fitted onto the outer periphery of the square screwdriver shaft, and the two work together; or the reduced diameter section of the threaded head 18 can be fixed to the third threaded hole 19 by tightening. Alternatively, the third threaded hole 19 can be modified into a square hole, and the reduced diameter section of the threaded head 18 can be set as a square rod and matched with the square hole to limit axial movement. Multiple second threaded holes 16 are provided on the top plate 14. Countersunk threaded heads are installed in the second threaded holes 16. The bottom end of the countersunk threaded head abuts against the top of the slide plate 13 to form multi-point support and improve overall stability.

[0039] The operation method of the hydrostatic guide rail assembly with integrated horizontal adjustment and locking functions includes the following steps: S1. Before assembling the slider 12 onto the slide rail 11, manually rotate the shaft 45 to rotate the cam 35, causing the arc-shaped guide groove 42 to engage with the guide rod 41 and move relative to it. Pull the locking block 34 back, causing the wedge rod 44 to disengage from the toothed surface of the stop plate 25. Manually insert the limiting rod 50 into the overlapping first limiting hole 43 and second limiting hole 49 to keep the wedge rod 44 in the avoidance position. After completing the assembly of the slider 12 and the slide rail 11, pull out the limiting rod 50. Rotate 45 in the opposite direction to rotate the cam 35. The wedge rod 44 is adjusted to extend into the stop plate 25 to form a locking state, and the limit rod 50 is inserted into the overlapping third and fourth limit holes to keep the wedge rod 44 in the working position, so as to switch to the locking limit state, thereby limiting the position of the multiple locking blocks 34 and the wedge rod 44 installed on the same axis; then the leveling mechanism is manually adjusted, and the double threaded sleeve 17 is rotated to generate axial displacement in the threaded engagement between the first threaded hole 15 and the threaded head 18, thereby realizing the height fine adjustment of the top plate 14 relative to the slide plate 13; S2. During normal operation, the external oil hole 63 injects pressurized oil into the oil passage to form a balanced oil film on the sliding channel 21 of the slider 12 and the slide rail 11, as well as the upper and lower surfaces and the force-bearing surfaces on both sides, so that the slider 12 moves with low friction; at the same time, the conical plug 36 is disengaged from the conical hole 31 under the action of oil pressure, and the locking block 34 is driven to the retracted position through the longitudinal rod 30, so that the wedge rod 44 and the stop plate 25 remain non-engaged. S3. When a power outage or hydraulic system malfunction causes a drop in oil supply pressure, weakening the load-bearing capacity of the balance oil film, the oil pressure in the third core oil passage 59 and the fourth core oil passage 60 reduces the holding force of the conical plug 36. Under the action of the return spring 38, the conical plug 36 retracts into the conical hole 31 and drives the longitudinal rod 30 to move. The longitudinal rod 30 drives the locking block 34 and the wedge rod 44 to move toward the stop plate 25, thereby allowing the wedge rod 44 to extend into the stop plate 25, realizing the self-triggering process of switching from the unlocked state to the locked state. S4. During the S3 driving process, when the locking block 34 moves towards the stop plate 25, the locking block 34 drives the wedge rod 44 to approach the stop plate 25. The constricted inclined surface at the end of the wedge rod 44 first forms a sliding contact with the tooth head of the stop plate 25. Under the action of the return spring 38, a wedge-in or pull-out reciprocating displacement occurs. The wedge rod 44 drives the longitudinal rod 30 to reciprocate, thereby changing the state of the return spring 38 to consume the sliding kinetic energy of the slider 12, and thus gradually buffering the inertial sliding of the slider 12. It dissipates energy and reduces the instantaneous impact of locking; at the same time, the conical plug 36 forms a squeezing contact with the subsequent hydraulic oil in the conical hole 31, and generates controlled micro-movements with the displacement of the longitudinal rod 30, thereby suppressing the sudden displacement and rebound vibration of the longitudinal rod 30 and further dissipating kinetic energy; thus, a damping effect is formed without additional independent damping components, so that the contact process between the wedge rod 44 and the stop plate 25 changes from abrupt braking to smooth damping deceleration, and reduces tooth surface impact wear, while improving the stability and controllability of hydraulic triggering action; S5. When the wedge rod 44 is pushed to the preset stroke, the stop plate 25 engages with the tooth surface structure of the wedge rod 44 under the continuous thrust of the locking block 34, and forms a mechanical limit in the tooth surface of the stop plate 25, thereby reliably locking the slider 12 relative to the slide rail 11, so as to suppress the undesirable slippage under abnormal pressure conditions and extend the service life of the slide rail 11 and the slider 12. S6. When disassembly or maintenance is required, reverse step S1 to retract the locking block 34 and drive the wedge rod 44 out of the tooth surface of the stop plate 25, keeping it separated from the stop plate 25. Then, in a state without locking interference, complete the extraction or insertion of the slider 12 relative to the slide rail 11.

Those skilled in the art should understand that all related improvements to the present invention fall within the protection and disclosure scope of the present invention.

The three sets of third threaded holes (19) are evenly distributed on the outer edge of the slide (13). The third threaded holes (19) are blind holes. The double-threaded sleeve (17) has external threads on the outside and internal threads on the inside. The bottom of the threaded head (18) is provided with a reduced-diameter threaded section. It is screwed into the third threaded hole (19). The threaded head (18) is located at the top of the slide (13). The threaded head (18) has an inner opening (20) for accommodating the adjustment tool. The top plate (14) has a first threaded hole (15) corresponding to the three sets of threaded heads (18). The first threaded hole (15) is screwed into the first threaded hole (15). The double threaded sleeve (17) is threaded onto the outer circumference of the threaded head (18). The top of the double threaded sleeve (17) has an operating port for inserting the tool and adjusting its rotation.

10. A method of operating the hydrostatic guide rail assembly with integrated horizontal adjustment and locking functions as described in any one of claims 1-9, characterized in that, Includes the following steps, S1. Before assembly, rotate the shaft (45) to make the locking block (34) retract and make the wedge rod (44) avoid the stop plate (25). Insert the limit rod (50) into the first limit hole (43) and keep it away from the second limit hole (49). After assembly, pull it out. Rotate the shaft (45) in the opposite direction to make the wedge rod (44) enter the stop plate (25) and insert the limit rod (50) into the third limit hole and the fourth limit hole to keep it in the working position. Rotate the double threaded sleeve (17) to cooperate with the first threaded hole (15) and the threaded head (18) to adjust the height of the top plate (14) relative to the slide plate (13). S2, the external oil hole (63) supplies oil to form an oil film in the sliding channel (21) and the force surface, so that the slider (12) slides. The oil pressure causes the conical plug (36) to exit the conical hole (31) and the locking block (34) to retract via the longitudinal rod (30). The wedge rod (44) and the stop plate (25) are not engaged. S3. When the supply pressure drops, the conical plug (36) retracts from the conical hole (31) under the action of the return spring (38) and drives the longitudinal rod (30) to move, which in turn drives the locking block (34) and the wedge rod (44) to move toward the stop plate (25) and triggers locking. The constricted inclined surface of the wedge rod (44) slides into or out of the tooth of the stop plate (25) and compresses the return spring (38) to gradually dissipate energy. The conical plug (36) and the hydraulic oil squeeze the micro-motion to form damping, reduce impact wear and improve triggering stability. S4. After the wedge rod (44) is in place, it is inserted into the toothed slot of the stop plate (25) and engaged to limit the movement, so as to reliably lock the slider (12) relative to the slide rail (11). S5. During disassembly and maintenance, reverse the operation of S1 to remove the wedge rod (44) from the stop plate (25) and remove the interference before removing the slider (12).
