A hydrostatic guideway is arranged on the surface of the lathe bed, and a workbench is arranged on the hydrostatic guideway and used for directionally transporting workpieces along the hydrostatic guideway. The grinding machine machining mechanism is arranged above the machine body and used for machining workpieces. The static pressure guide rail comprises an oil film supporting state and a hard supporting state which can be switched mutually, and when the static pressure guide rail is in the oil film supporting state, the static pressure guide rail supports the workbench through a static pressure oil film; when in the hard supporting state, the static pressure guide rail can generate hard supporting on the workbench.

Description

Technical Field

[0001] The present application relates to the technical field of mechanical grinders, and in particular to a hydrostatic guide rail grinder and a method for processing a hydrostatic guide rail mating surface. Background Art

[0002] Traditional sliding / rolling guides have obvious defects under heavy-load and high-speed conditions. Due to friction, frictional heat is easily accumulated, which can cause thermal deformation errors in the guides, and the thermal deformation errors are usually too large. This thermal deformation can seriously affect the machining accuracy stability of large workpieces, making it difficult for the processed workpieces to meet high-precision requirements. Based on this, the application of hydrostatic guides has been developed. Hydrostatic guides use a hydrostatic oil film to support the worktable of the grinder, avoiding the above problems. However, hydrostatic guides have the risk of hydrostatic oil film failure during use. Failure of the hydrostatic oil film can cause damage to the grinder, resulting in the risk of downtime.

[0003] In order to solve these problems, it is urgent to develop a new type of hydrostatic guide rail grinding machine structure. Summary of the Invention

[0066] See Figure 1 As shown, Figure 1This is a schematic diagram of the structure of a hydrostatic guide rail grinder provided in an embodiment of the present application. The hydrostatic guide rail grinder includes a bed 1000 and a grinding mechanism 3000. The bed 1000 is provided with hydrostatic guide rails, on which a worktable 2000 is mounted. The worktable 2000 is used to directional transport a workpiece along the hydrostatic guide rails. The grinding mechanism 3000 is positioned above the bed 1000 and is used to process the workpiece.

[0067] The hydrostatic guide rails and worktable 2000 are designed to support the worktable 2000 through a hydrostatic oil film, reducing friction and kinematic errors. This ensures high precision when the worktable 2000 directionally transports workpieces, thereby improving the grinding machine's machining accuracy. The hydrostatic oil film transforms solid contact into liquid friction, significantly reducing wear and extending the guide rail's service life. The hydrostatic oil film has a strong load-bearing capacity, capable of supporting the weight of the worktable 2000 and the workpiece, maintaining excellent working condition even under high cutting forces during machining. The worktable 2000's surface can be equipped with an electro-permanent magnet to attract workpieces.

[0068] The support states of the hydrostatic guide rail include at least an oil film support state and a rigid support state, which can be switched between each other. When in the oil film support state, the hydrostatic guide rail uses the hydrostatic oil film to support the workbench; when in the rigid support state, the hydrostatic guide rail can provide rigid support for the workbench. The state switching of the hydrostatic guide rail can ensure that when the hydrostatic oil film is at risk of failure, it switches to the rigid support state to continue supporting the workbench, avoiding rigid collisions and wear between structures. The dual-state switching design of the hydrostatic guide rail can automatically or manually switch to the rigid support state when the hydrostatic oil film is at risk of failure due to oil leakage, insufficient oil pressure, oil contamination, etc., so that the workbench can still maintain stable support and avoid processing interruptions due to oil film failure. Avoid the risk of sudden downtime and improve the fault tolerance of the system. It can ensure that when the hydrostatic oil film is at risk of failure, it switches to the rigid support state to continue supporting the workbench, avoiding rigid collisions and wear between structures.

[0069] In order to address the problem of excessive thermal deformation errors caused by frictional heat accumulation in traditional sliding / rolling guideways under heavy-load and high-speed working conditions, the hydrostatic guideway grinder supports the workbench 2000 through a hydrostatic oil film, reducing the generation of frictional heat and effectively avoiding the influence of thermal deformation on machining accuracy, thereby improving the machining accuracy and stability of large workpieces. Rolling guideway grinders have a creeping phenomenon when moving at low speeds, which affects the precise control of the grinding position and grinding amount, resulting in rough machined surface quality. The hydrostatic guideway grinder of this application relies on a hydrostatic oil film to achieve stable movement, is not affected by low-speed creeping, meets the requirements of high-precision surface machining, and expands the application of grinders in the field of precision machining.

[0070] In some embodiments of the present application, reference is made to the accompanying Figure 2-Figure 4 , Figure 2 This is a top view of the bed provided in an embodiment of the present application. Figure 3 This is a front view of the workbench provided in an embodiment of the present application. Figure 4 for Figure 2 The partial enlarged view of A in the middle shows that the hydrostatic guide rail includes a matching groove 1001 formed on the surface of the bed 1000 , and an oil supply module 4000 and a support module 5000 disposed in the matching groove 1001 .

[0071] The workbench 2000 is provided with a mating slider 2001, which is configured to extend into the mating groove 1001. The oil supply module 4000 has two states: oil supply and non-oil supply. When the oil supply module 4000 is in the oil supply state, the hydrostatic guide rail is in an oil film support state. The oil supply module 4000 is used to form a hydrostatic oil film between the mating groove 1001 and the mating slider 2001.

[0072] When the oil supply module 4000 is in a non-oil supply state, the static pressure guide rail is in a rigid support state, and the support module 5000 is used to rigidly support the matching slider 2001.

[0073] A matching groove 1001 is precisely opened on the surface of the bed 1000 , and its shape and size need to be determined according to the matching slider 2001 of the workbench 2000 and the design requirements of the entire grinder to ensure good matching accuracy and guiding performance with the matching slider 2001 .

[0074] The oil supply module 4000 generally includes an oil pump, an oil source, oil piping, and various control valves. The oil pump delivers oil from the source via the oil piping to the mating groove 1001. The control valves regulate the oil flow and pressure to meet the requirements for forming a static oil film under various operating conditions. The oil piping layout requires careful planning to avoid interfering with the movement of the workbench 2000 and the installation of other components. Furthermore, the piping must be properly sealed to prevent oil leakage.

[0075] The support modules 5000 are typically evenly distributed within the mating grooves 1001 in a matrix configuration. The thickness of the support modules 5000 is appropriately configured to ensure that the static oil film formed by the oil supply module 4000 during stable oil supply is thicker than the thickness of the support modules 5000. When the static oil film is less than the thickness of the support modules 5000, the support modules 5000 are able to support the workbench 2000, providing rigid support. This layout ensures that the load from the workbench 2000 is evenly transferred to the bed 1000, avoiding localized stress concentration. Furthermore, their spacing from the oil supply module 4000 allows for spatial decoupling of lubrication and support functions.

[0076] The material of the support module 5000 can be selected from metals with high hardness and wear resistance to ensure that it can bear the weight of the workbench 2000 and the workpiece.

[0077] When the oil supply module 4000 is in the oil supply state, the oil pump inside it will transport the oil in the oil source to the mating groove 1001 through the oil pipe. At the same time, the control valve will adjust the flow and pressure of the oil so that the oil forms a hydrostatic oil film with a certain pressure and bearing capacity between the mating groove 1001 and the gap between the mating slider 2001. At this time, the workbench 2000 relies on the support of the hydrostatic oil film to achieve contactless and low-friction movement with the mating groove 1001. This state can ensure that the workbench 2000 moves along the hydrostatic guide rail with high precision and stability, is suitable for normal processing conditions, and provides good basic conditions for the high-precision processing of the grinding machine. For example, when performing precision grinding, only by forming a stable hydrostatic oil film in the oil supply state can the accuracy of the workbench movement be ensured, and thus the processing accuracy can be guaranteed.

[0078] When the oil supply module 4000 is in a non-oil supply state, the oil pump stops working actively or passively and no longer delivers oil to the matching groove 1001. At this time, the support module 5000 plays a role in supporting the matching slider 2001.

[0079] Specifically, when the thickness of the static oil film is greater than that of the support module 5000, the static oil film supports the workbench 2000. When the static oil film is not thick enough, the thickness of the support module 5000 is greater than that of the static oil film, and the support module 5000 then supports the workbench 2000. By varying the oil supply, the thickness of the static oil film is changed, thereby achieving a switch between the oil film support state and the rigid support state.

[0080] The non-oil supply state typically occurs during the initial system startup when the oil pressure hasn't reached the required level, when a system failure causes insufficient oil pressure, or when energy conservation is necessary. In these situations, the support module 5000, acting as a backup support structure, prevents direct metal-to-metal contact between the mating slider 2001 and the mating groove 1001, avoiding wear or jamming caused by friction. This ensures that the worktable 2000 maintains a certain level of stability and doesn't affect the basic operation of the grinder. For example, if a sudden system failure causes a brief oil supply interruption, the support module 5000 can intervene promptly, buying time for the operator to resolve the problem and minimizing the impact on machining quality.

[0081] The precise fit between the matching groove 1001 and the matching slider 2001 and the supporting effect of the hydrostatic oil film enable the workbench 2000 to achieve high-precision directional movement along the hydrostatic guide rail, reduce motion errors, and improve the machining accuracy of the grinder.

[0082] The presence of the hydrostatic oil film converts the solid contact between the mating slider 2001 and the mating groove 1001 into liquid friction, greatly reducing frictional resistance and energy loss during the movement of the workbench 2000, while also reducing wear and increasing the service life of the guide rail.

[0083] The static oil film formed by the pressure oil provided by the oil supply module 4000 between the mating groove 1001 and the mating slider 2001 has a high load-bearing capacity and can withstand the weight of the workbench 2000 and the workpiece, ensuring the stability of the workbench 2000 during movement, and can maintain a good working condition even if it is subjected to large cutting forces during processing.

[0084] During normal operation, the oil supply module 4000 forms a hydrostatic oil film to achieve contactless, low-friction movement, ensuring high precision and stability. When an oil supply failure occurs, such as insufficient oil pressure or oil pump failure, the support module 5000 immediately intervenes to prevent direct metal contact from causing wear or jamming, forming a double safety guarantee. The system design has fault tolerance, allowing short-term oil supply interruptions to maintain basic functions, reducing the impact on processing quality, and is suitable for continuous production scenarios. In addition, the system also has an intelligent automatic switching mechanism, which monitors the oil film pressure in real time based on oil pressure feedback. When the pressure is lower than the threshold, the support unit is automatically triggered, and the preload force of the rigid support unit can be dynamically adjusted with the load to ensure stability after switching.

[0085] During continuous production, the support module 5000 can maintain basic functions when the oil supply is interrupted for a short time, giving operators time to respond, reducing the negative impact of sudden downtime on processing quality, and enhancing production stability and reliability.

[0086] In some embodiments of the present application, the matching groove 1001 includes a first strip-shaped groove 1002 and a second strip-shaped groove 1003 opened along the length direction of the bed 1000 .

[0087] The inner wall of the first strip-shaped groove 1002 is set to be a plane, and the inner wall of the second strip-shaped groove 1003 is set to be a V-shaped concave surface.

[0088] The mating slider 2001 of the workbench 2000 includes a first slider 2002 mating with the first strip groove 1002 and a second slider 2003 mating with the second strip groove 1003 .

[0089] A first groove 1002 is precisely cut along the length of the bed 1000, its inner wall machined to a flat surface. Similarly, a second groove 1003 is cut along the length of the bed 1000, its inner wall configured as a V-shaped concave surface. The angle and dimensions of the V-shaped concave surface are designed based on the specific requirements of the grinding machine; common V-angles are 90° or 120°.

[0090] The first sliding block 2002 is installed at the bottom of the workbench 2000 , or the first sliding block 2002 and the bottom of the workbench 2000 are integrally formed.

[0091] The bottom surface of the first slider 2002 is machined to match the inner surface of the first strip groove 1002. Its flatness and finish must match those of the first strip groove 1002 to ensure a uniform gap between them. The length and width of the first slider 2002 should be slightly smaller than the inner dimensions of the first strip groove 1002 to allow sufficient clearance for the formation of a static oil film. Oil holes and oil grooves are also required on the first slider 2002 to evenly distribute the oil provided by the oil supply module 4000 to the contact surface with the first strip groove 1002.

[0092] The second slider 2003 is installed at the bottom of the workbench 2000, or the second slider 2003 is integrally formed with the bottom of the workbench 2000. The second slider 2003 cooperates with the V-shaped concave surface of the second strip groove 1003. Its shape is a V-shaped block adapted to the V-shaped concave surface, and the V-shaped angle is the same as the V-shaped concave angle of the second strip groove 1003. The V-shaped surface of the second slider 2003 also needs to be processed with high precision to ensure the fit with the V-shaped concave surface. Oil holes and oil grooves also need to be provided on the second slider 2003 for the distribution of oil. The size of the second slider 2003 should be designed according to the size of the second strip groove 1003, so as to ensure that it can slide freely in the V-shaped concave surface and stably support the workbench 2000 during operation.

[0093] The flat surface of the first groove 1002 cooperates with the flat surface of the first slider 2002 to provide precise guidance in one direction, limiting the freedom of movement of the worktable 2000 in that direction. The V-shaped concave surface of the second groove 1003, in conjunction with the V-shaped surface of the second slider 2003, provides excellent positioning and guidance in the other direction. This combination effectively constrains the movement of the worktable 2000, forcing it to perform highly precise linear motion along the length of the bed 1000. This reduces swing and deflection of the worktable 2000 during movement, thereby improving the grinding machine's machining accuracy.

[0094] This structural design of the mating groove 1001 and the mating slider 2001 is relatively easy to install and adjust. The planar first groove 1002 and first slider 2002 are easy to machine and measure, making it easy to ensure their levelness and straightness during installation. The V-shaped second groove 1003 and second slider 2003 can be precisely aligned with the V-groove by adjusting the position and angle of the V-block during installation. Any wear or loss of precision during use is also easily adjustable and repairable.

[0095] Due to the different structures of the first and second grooves 1002, 1003, they constrain the worktable 2000 in different ways, allowing the hydrostatic guide rail to adapt to different machining conditions. For example, during high-precision grinding, the flat-fitting first groove 1002 provides more precise guidance, ensuring dimensional accuracy. Furthermore, when encountering large lateral forces during machining, the V-shaped second groove 1003 better withstands these forces, preventing the worktable 2000 from shifting and improving the grinding machine's machining stability and reliability.

[0096] The flat surface of the first groove 1002 bears the primary vertical load (such as the weight of the workpiece), increasing the contact area to reduce pressure. The V-shaped surface of the second groove 1003 distributes lateral forces (such as cutting forces), dispersing stress through inclined contact. These two elements work together to enhance system rigidity and reduce the risk of deformation, making them particularly suitable for heavy-load or highly dynamic working conditions.

[0097] The V-shaped surface of the second groove 1003 uses the adaptive properties of inclined contact to automatically correct assembly errors or slight offsets, reducing the difficulty of installation and commissioning. Over long-term use, the wear distribution of the V-shaped surface is more even, and combined with the support of the flat surface, it can partially compensate for the wear gap and extend the precision life.

[0098] The wedge-shaped structure of the V-shaped surface of the second groove 1003 facilitates the formation of a lubricating oil film, reducing friction and wear. Conventional lubrication methods can be used on the flat surface, simplifying maintenance. The combined design of these two elements can also incorporate a scraper or sealing device to prevent wear debris from invading the guide surface, reducing wear caused by contamination.

[0099] In some embodiments, seven oil supply modules 4000 are precisely installed at appropriate intervals along the length of the bed 1000 in the first strip groove 1002 and the second strip groove 1003. Support modules 5000 are precisely installed in the gaps between each oil supply module 4000. The height of the support module 5000 needs to be precisely adjusted according to the gap between the V-groove and the mating slider 2001 so that it can evenly support the mating slider 2001 in the non-oil supply state. Support modules 5000 are interspersed between the gaps of each oil supply module 4000. When the oil supply module 4000 fails, the thickness of the support module 5000 is set so that it can quickly take over the work, preventing the mating slider 2001 from directly contacting the V-groove and avoiding damage to the equipment.

[0100] The hydrostatic cavity plate, a specific form of the hydrostatic guideway grinder's oil supply module 4000, is equipped with multiple tiny oil chambers or grooves. The shape, size, and distribution of these oil chambers are carefully designed, typically arranged in a regular pattern, such as evenly distributed circular or square chambers. This ensures that, when pressurized oil is introduced, a uniform hydrostatic oil film forms between the mating surfaces.

[0101] When the oil supply module 4000 is connected to the oil supply system, pressurized oil is delivered through pipelines to the various oil chambers of the hydrostatic chamber plate. As the oil pressure within the oil chamber gradually increases, the oil overflows from the oil chamber and diffuses between the mating groove and the mating slider 2001, forming a hydrostatic oil film with a certain pressure and thickness.

[0102] In some embodiments of the present application, a driving mechanism 6000 is further configured on the bed 1000, the fixed end of the driving mechanism 6000 is arranged on the bed 1000, and the movable end of the driving mechanism 6000 is connected to the workbench 2000. The driving mechanism 6000 is used to drive the workbench 2000 to move along the hydrostatic guide rail. Common driving mechanisms 6000 include screw nut drive, linear motor drive, hydraulic drive, etc. For this type of hydrostatic guide rail grinder, a suitable driving mechanism 6000 can be selected based on factors such as the precision requirements, load capacity and working speed of the grinder. For example, if high precision and high speed are required, a linear motor drive can be selected; if the load is large, a hydraulic drive or a large-lead screw nut drive can be considered.

[0103] The fixed end of the drive mechanism 6000 is securely mounted to the bed 1000 via bolts or welding. For a screw-nut drive, the screw is typically mounted on one side or in the middle of the bed 1000, parallel to the hydrostatic guide rails, to ensure accurate transmission of the driving force to the worktable 2000. For a linear motor drive, the stator is mounted on the bed 1000, and the mover is connected to the worktable 2000. Hydraulically driven hydraulic cylinders are also typically mounted inside or on the side of the bed 1000 and connected to the worktable 2000 via hydraulic lines.

[0104] The connection between the movable end of the drive mechanism 6000 and the workbench 2000 must be reliable and precise. For the screw nut drive, the nut is fixed to the bottom of the workbench 2000 by a connecting block to ensure that the movement of the nut can accurately drive the workbench 2000 to move. The mover of the linear motor and the workbench 2000 are connected through a connecting plate or directly integrated into the workbench 2000 structure to ensure a uniform air gap between the mover and the stator. The hydraulically driven piston rod is connected to the workbench 2000 by a spherical bearing or other flexible connection method to accommodate slight posture changes of the workbench 2000 during movement.

[0105] The drive mechanism 6000 provides a smooth driving force, enabling the worktable 2000 to move at a constant speed on the hydrostatic guide rails. This is because the moving components of the drive mechanism 6000 are precisely machined and assembled, minimizing vibration and impact during movement. For example, the hydraulic drive system, by regulating the flow and pressure of the hydraulic oil, enables smooth starting and stopping of the worktable 2000 and stepless speed regulation, avoiding machining errors caused by sudden speed changes.

[0106] The drive mechanism 6000 can typically be integrated with the grinding machine's control system to achieve automated control. Programming allows precise setting of parameters such as the motion trajectory, speed, and acceleration of the worktable 2000 to accommodate diverse machining requirements. For example, when grinding complex shapes, the drive mechanism 6000 can be controlled by the CNC system to move the worktable 2000 along a pre-set curved trajectory, improving machining efficiency and quality.

[0107] In some embodiments of the present application, the hydrostatic guide rail also includes an oil pressure detection device (not shown in the figure) configured in the mating groove 1001. When the oil pressure data detected by the oil pressure detection device is greater than the oil pressure threshold, the oil supply module 4000 is in an oil supply state; when the oil pressure data detected by the oil pressure detection device is less than the oil pressure threshold, the oil supply module 4000 is in a non-oil supply state.

[0108] The oil pressure detection device should be installed within the mating groove 1001 at a location where it can accurately detect the static oil film pressure. Typically, it can be installed at the bottom or side of the mating groove 1001, near the oil outlet of the oil supply module 4000. This allows for timely and accurate detection of oil pressure changes as the oil film forms. For the first and second strip grooves 1002, 1003, oil pressure detection devices can be installed separately to independently monitor the oil pressure at different locations.

[0109] The oil pressure detection device can be secured to the wall of the mating groove 1001 using threaded, flanged, or ferrule connections. During installation, ensure that the detection device fits tightly against the inner wall of the mating groove 1001 to prevent oil leakage that could affect detection accuracy. Furthermore, ensure that the detection device's sensor probe is in direct contact with the oil to obtain accurate oil pressure data.

[0110] The oil pressure detection device needs to establish an electrical connection with the oil supply module 4000 to transmit the detected oil pressure data to the control unit of the oil supply module 4000. This connection can be achieved through electrical wires or data cables, and the connection lines should be properly protected to prevent oil corrosion and mechanical damage.

[0111] When the oil pressure detection device detects that the oil pressure data is greater than the oil pressure threshold, it indicates that the hydrostatic oil film has formed and the oil pressure is sufficient. At this time, the oil supply module 4000 is in the oil supply state, able to continuously provide a stable oil supply to the oil film, ensuring good lubrication and support between the workbench 2000 and the hydrostatic guide rail. When the oil pressure data is less than the oil pressure threshold, the oil supply module 4000 is in the non-oil supply state, avoiding unnecessary oil supply, saving energy, and preventing damage to the system due to excessive oil pressure.

[0112] In some embodiments of the present application, reference is made to the accompanying Figure 5 and attached Figure 6 , Figure 5 This is a front view of the hydrostatic guide rail grinder provided in an embodiment of the present application. Figure 6 This is a top view of the hydrostatic guide rail grinder provided in an embodiment of the present application. The grinding machine processing mechanism 3000 shown includes: a gantry 3010, a horizontal grinding mechanism 3020 and a vertical grinding mechanism 3030.

[0113] The horizontal grinding mechanism 3020 is arranged on the gantry 3010 via a first moving mechanism. The first moving mechanism can drive the horizontal grinding mechanism 3020 to move horizontally and vertically along the gantry 3010 .

[0114] The vertical grinding mechanism 3030 is arranged on the gantry 3010 via a second moving mechanism. The second moving mechanism can drive the vertical grinding mechanism 3030 to move horizontally and vertically along the gantry 3010 .

[0115] The dual-column support structure of the gantry 3010 effectively disperses the load, and the large crossbeam span makes it suitable for machining wide parts, resulting in better surface roughness on the machined workpieces and strong dynamic stability.

[0116] The crossbeams and columns are internally arranged with a crisscross rib layout to improve the rigidity of the casting and avoid low-speed creeping; the fully enclosed frame design reduces iron chips and coolant splashing, improving environmental stability.

[0117] The horizontal grinding mechanism 3020 and the vertical grinding mechanism 3030 can independently move horizontally and vertically, respectively, and can grind the workpiece from different angles. The first moving mechanism and the second moving mechanism can accurately control the movement position and speed of the horizontal grinding mechanism 3020 and the vertical grinding mechanism 3030. During the processing, the relative position and feed rate between the grinding wheel and the workpiece can be precisely adjusted according to the processing requirements of the workpiece, thereby ensuring processing accuracy. For example, when performing high-precision surface grinding, the horizontal grinding mechanism 3020 can be used to accurately trim and grind the surface through the horizontal movement and vertical movement. For some workpieces with vertical or inclined surfaces, the vertical grinding mechanism 3030 can better adapt to their shape and perform high-precision grinding.

[0118] The two grinding mechanisms can operate simultaneously, processing different parts of the workpiece, thereby improving processing efficiency. For example, when processing large, flat workpieces, the horizontal grinding mechanism 3020 can grind a large area of the workpiece's top surface, while the vertical grinding mechanism 3030 can simultaneously grind the workpiece's sides, significantly reducing processing time. Furthermore, by rationally planning the motion paths and processing sequences of the two grinding mechanisms, efficient collaborative processing can be achieved, further improving production efficiency.

[0119] In some embodiments of the present application, the horizontal grinding mechanism 3020 includes a first base 3021 , a first rotating motor 3022 , and a horizontal grinding head 3023 .

[0120] The first moving mechanism includes a first horizontal moving motor 3024, a first horizontal lead screw 3025, a first vertical lead screw, a first vertical moving motor 3026, and a first slide 3027. The first rotary motor 3022 and the horizontal grinding head 3023 are mounted on the first base 3021. The first rotary motor 3022 is used to drive the horizontal grinding head 3023 for rotation. The first horizontal moving motor 3024 and the first horizontal lead screw 3025 are mounted on the gantry 3010. The first slide 3027 is movably engaged with the first horizontal lead screw 3025 and is movable along the first horizontal lead screw 3025. The first vertical lead screw and the first vertical moving motor 3026 are mounted on the first slide 3027. The first slide 3027 is movably engaged with the first vertical lead screw and is movable along the first vertical lead screw.

[0121] The coordination of the first horizontal motor 3024 and the first horizontal lead screw 3025, as well as the coordination of the first vertical motor 3026 and the first vertical lead screw, allows precise control of the horizontal and vertical positions of the horizontal grinding head 3023. This precise position control enables the grinder to perform high-precision grinding of workpieces according to pre-set machining paths, meeting the processing requirements of workpieces of varying shapes and sizes. The horizontal grinding head 3023 can achieve independent horizontal and vertical movement on the gantry 3010. This flexible movement allows the grinder to adapt to different grinding tasks.

[0122] In some embodiments of the present application, the vertical grinding mechanism 3030 includes a second base 3031, a second rotary motor 3032, and a vertical grinding head 3033. The second movement mechanism includes a second horizontal movement motor 3034, a second horizontal lead screw 3035, a second vertical lead screw, a second vertical movement motor 3036, and a second slide 3037. The second rotary motor 3032 and the vertical grinding head 3033 are disposed on the second base 3031, and the second rotary motor 3032 is used to drive the vertical grinding head 3033 to rotate.

[0123] The second horizontal moving motor 3034 and the second horizontal lead screw 3035 are disposed on the gantry 3010 , and the second slide 3037 is movably engaged with the second horizontal lead screw 3035 and can move along the second horizontal lead screw 3035 .

[0124] The second vertical lead screw and the second vertical moving motor 3036 are disposed on a second slide 3037 . The second slide 3037 is movably engaged with the second vertical lead screw and can move along the second vertical lead screw.

[0125] The vertical grinding mechanism 3030 works in conjunction with the horizontal grinding mechanism 3020, enabling workpiece grinding from various directions, increasing processing flexibility and versatility. The combination of the second horizontal motor 3034, the second horizontal lead screw 3035, and the second vertical motor 3036, the second vertical lead screw, precisely controls the horizontal and vertical position of the vertical grinding head 3033.

[0126] In some embodiments of the present application, a rotation adjustment mechanism 3040 is disposed between the vertical grinding head 3033 and the second base 3031 , and the rotation adjustment mechanism 3040 is used to drive the vertical grinding head 3033 to rotate in a direction perpendicular to the second base 3031 .

[0127] In some embodiments, the rotation adjustment mechanism 3040 includes a servo motor, a tooth disc positioning structure and a hydraulic locking device. The output shaft of the servo motor is connected to the rotating shaft of the vertical grinding head 3033 through a coupling and other transmission components. The tooth disc positioning structure is respectively installed with tooth discs that cooperate with each other at the connection parts of the second base 3031 and the vertical grinding head 3033. A hydraulic locking device is installed around the tooth disc positioning structure. The device is mainly composed of a hydraulic cylinder, a piston, a seal, etc. After the tooth disc is positioned, high-pressure oil is injected into the hydraulic cylinder through the hydraulic system. The oil pushes the piston to move, so that the piston generates enough pressure to tightly press the tooth disc to prevent the grinding head from rotating due to external forces such as cutting force during the processing process, thereby ensuring the stability of the positioning.

[0128] The configuration of the rotation adjustment mechanism 3040 can achieve precise rotation control of one degree and one minute and a rotation range of ±90°, so that the vertical grinding head 3033 can meet the processing requirements of various complex angles.

[0129] A method for machining a hydrostatic guide rail mating surface, applicable to the above-mentioned hydrostatic guide rail grinding machine, comprising:

[0130] Step 1: Produce one piece each of an integral flat V male mold 7001, a single V male mold 7002, an integral flat V female mold 7003, and a single V female mold 7004.

[0131] Specifically, the company selected appropriate mold steel materials and, based on the design dimensions, produced the blanks for the integral flat V male mold 7001, the single-piece V male mold 7002, the integral flat V female mold 7003, and the single-piece V female mold 7004 through forging, rough machining, and semi-finishing processes. Heat treatment was then performed to enhance the material's hardness and stability, followed by finishing to ensure that the dimensional accuracy and surface quality of each mold met the design standards. This provided a precise foundation for subsequent grinding and matching, ensuring the initial accuracy of each mold. This enabled subsequent machining to better ensure the accuracy of the mating surfaces and reduce the accumulation of machining errors.

[0132] Step 2: Grind the single V male mold 7002, then use the single V male mold 7002 to grind the V-shaped surface of the overall flat V female mold 7003, and grind out the flat rail surface of the overall flat V female mold 7003.

[0133] Specifically: The single V-shaped male mold 7002 is clamped onto a high-precision grinding machine. Using a suitable grinding wheel, the V-shaped surface is ground according to the designed dimensions and precision requirements. Grinding parameters are controlled to ensure the V-shaped surface's shape accuracy and surface roughness. After grinding the single V-shaped male mold 7002, it is then matched with the V-shaped surface of the integral flat V female mold 7003. During the matching process, continuous measurement and adjustments are made to ensure a close fit between the two V-shaped surfaces. Simultaneously, the flat rail surface of the integral flat V female mold 7003 is ground to ensure its flatness.

[0134] Through the precise grinding and matching of the single V male mold 7002, it can ensure that the V-shaped surface and the flat rail surface of the overall flat V female mold 7003 have high-precision matching accuracy, providing a good foundation for the subsequent matching of the guide rail and the slider, reducing the matching clearance, and improving the guiding accuracy and stability of the guide rail.

[0135] Step 3: Use the single V male mold 7002 to grind the V-shaped surface of the single V female mold 7004.

[0136] Specifically: The ground single V male mold 7002 and single V female mold 7004 are clamped on a dedicated grinding machine. The relative positions of the two are adjusted so that their V-shaped surfaces mate with each other. Grinding is performed using a suitable abrasive. The V-shaped surface of the single V female mold 7004 is continuously trimmed and measured until the V-shaped surface achieves a high-precision fit with the V-shaped surface of the single V male mold 7002.

[0137] Further improve the V-shaped surface accuracy of the single V master mold 7004, ensure its matching accuracy with other molds and guide rail components, ensure the movement accuracy and stability of the entire hydrostatic guide rail system, and reduce shaking and deviation during movement.

[0138] Step 4: Use the single V female mold 7004 to grind the overall flat V male mold 7001, and then use the overall flat V female mold 7003 to grind the overall flat V male mold 7001.

[0139] Specifically, the single V-shaped female mold 7004 is first ground against the integral flat V male mold 7001. Through continuous adjustment and grinding, the mating surfaces are perfectly aligned. The integral flat V-shaped female mold 7003 is then ground against the integral flat V male mold 7001 to further optimize the precision of the mating surfaces. This repeated grinding process significantly improves the precision of the integral flat V male mold 7001, ensuring high-precision machining of the guide rail grooves when used as a mold. This, in turn, enhances the manufacturing accuracy of the entire hydrostatic guide rail and improves the grinding machine's machining performance.

[0140] Step 5: Use the single V-shaped male mold 7002 to grind out the V-shaped concave surface of the second groove 1003, and then use the overall flat V-shaped male mold 7001 to grind out the first groove 1002.

[0141] Specifically, the single V-shaped male mold 7002 is mounted on the grinding machine and its position and angle are adjusted to align with the machining location of the second groove 1003. Based on the design dimensions of the V-shaped concave surface of the second groove 1003, an appropriate grinding wheel and grinding process are selected and grinding is performed. Measurements and adjustments are made during the machining process to ensure the accuracy of the V-shaped concave surface. After machining the second groove 1003, the integral flat V-shaped male mold 7001 is installed and ground according to the design requirements of the first groove 1002 to ensure its flatness and dimensional accuracy.

[0142] The use of high-precision molds for groove processing can ensure the high precision of the first groove 1002 and the second groove 1003, so that the matching slider 2001 of the workbench and the groove have good matching accuracy, improve the guiding performance and load-bearing capacity of the hydrostatic guide rail, and ensure the smoothness and accuracy of the movement of the grinder workbench.

[0143] Step 6: Use the single V-shaped mother mold 7004 to grind the V-shaped surface of the second slider, install the oil supply module 4000 in the matching groove, and grind the oil supply module 4000 based on the V-shaped surface of the single V-shaped mother mold 7004.

[0144] Specifically: Clamp the single V-mother mold 7004 onto a grinding machine and grind the V-shaped surface of the second slider to ensure that the V-shaped surface meets the design requirements. After installing the oil supply module 4000 in the matching groove, use the V-shaped surface of the single V-mother mold 7004 as a reference to grind or fine-tune the oil supply module 4000 to achieve a good fit with the matching groove and the V-shaped surface of the second slider.

[0145] The V-shaped surface accuracy of the second slider is ensured, allowing it to better fit within the second groove. Grinding the oil supply module 4000 with the single V master mold 7004 as a reference ensures the installation accuracy of the oil supply module 4000 within the matching groove, ensuring the uniform formation of the hydrostatic oil film and improving the lubrication and load-bearing performance of the hydrostatic guideway.

[0146] Step 7: Use the integral flat V-mother 7003 to grind the first slider 2002.

[0147] Specifically, the integral flat V-shaped master mold 7003 and the first slider 2002 are clamped on a grinding machine. Through the grinding process, the surface of the first slider 2002 is continuously adjusted and ground to achieve a high-precision fit with the flat rail surface of the integral flat V-shaped master mold 7003. During the grinding process, tools such as a flatness measuring instrument are used to monitor and control the fit accuracy in real time.

[0148] Improve the matching accuracy between the first slider 2002 and the first strip groove 1002, reduce the matching clearance, enhance the guiding accuracy and stability of the hydrostatic guide rail, ensure the smooth movement of the workbench on the hydrostatic guide rail, and thus improve the processing accuracy and quality of the grinder.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
