[0034] Referring to FIG. 1 , according to some embodiments of the present application, the horizontal grinder 100 has a first direction, a second direction, and a third direction that are perpendicular to each other. When the horizontal grinder 100 is placed in the direction shown in FIG. 1 , the first direction is the X direction shown in FIG. 1 , the second direction is the Y direction shown in FIG. 1 , and the third direction is the Z direction shown in FIG. 1 . In addition, in one embodiment, the first direction can be understood as the width direction of the horizontal grinder 100, the second direction can be understood as the length direction of the horizontal grinder 100, and the third direction can be understood as the height direction of the horizontal grinder 100. In order to facilitate the explanation of the present application, the following content is uniformly described by taking the first direction as the width direction of the horizontal grinder 100, the second direction as the length direction of the horizontal grinder 100, and the third direction as the height direction of the horizontal grinder 100 as an example.

[0035] Referring to FIG. 1 , a horizontal grinder 100 according to some embodiments of the present application includes a bed 1, a grinder 2, a displacement drive mechanism 3, and a storage turntable mechanism 4. As shown in FIG. 1 and FIG. 2 , the bed 1 includes two supports 11, and the two supports 11 are arranged relative to each other in the width direction of the horizontal grinder 100, and the two supports 11 are also in a spaced state, that is, there is a space between the two supports 11. In the height direction of the horizontal grinder 100, the displacement drive mechanism 3 is arranged above the support 11, wherein in the width direction of the horizontal grinder 100, along the length direction of the displacement drive mechanism 3, one end of the displacement drive mechanism 3 is assembled with one support 11, and the other end of the displacement drive mechanism 3 is assembled with another support 11. It can also be understood that the two supports 11 are used to support the two ends of the displacement drive mechanism 3 respectively, so as to achieve the effect of the displacement drive mechanism 3 being arranged above the bed 1.

[0036] The displacement drive mechanism 3 can be movably mounted on the bed 1. Specifically, the displacement drive mechanism 3 can move along the length direction of the bed 1 (i.e., the length direction of the horizontal grinder 100). Since the grinder 2 is fixedly mounted on the displacement drive mechanism 3, during the movement of the displacement drive mechanism 3 along the length direction of the bed 1, the grinder 2 is driven by the displacement drive mechanism 3 to move relative to the bed 1 along the length direction of the bed 1, that is, the displacement drive mechanism 3 drives the grinder 2 to move relative to the bed 1 along the length direction of the horizontal grinder 100.

[0037] As shown in FIG. 1 , the displacement drive mechanism 3 may include a first movable member 31 and a second movable member 32 that are assembled in cooperation, wherein the first movable member 31 is used to be assembled in cooperation with the bed 1. When the first movable member 31 is assembled on the bed 1, along the length direction of the first movable member 31, one end of the first movable member 31 is assembled in cooperation with a support 11, and the other end of the first movable member 31 is assembled in cooperation with another support 11. It can also be understood that the two supports 11 are used to support the two ends of the first movable member 31 respectively, so as to achieve the effect that the first movable member 31 is arranged above the bed 1. And the first movable member 31 is slidably assembled on the bed 1, so the first movable member 31 is slidably assembled on the bed 1 along the length direction of the bed 1, so as to achieve the effect that the displacement drive mechanism 3 can slide along the length direction of the bed 1. It is worth noting that since the first movable member 31 moves relative to the bed 1 along the length direction of the bed 1, during the process of the first movable member 31 moving along the length direction of the horizontal grinder 100, the first movable member 31 drives the second movable member 32 assembled on the first movable member 31 to move along the length direction of the horizontal grinder 100, thereby achieving the effect of moving the grinder 2 assembled on the second movable member 32 along the length direction of the horizontal grinder 100.

[0038] In addition, when the displacement drive mechanism 3 is assembled on the bed 1, the second movable member 32 moves relative to the first movable member 31 along the height direction of the horizontal grinder 100, and the grinder 2 is assembled on the second movable member 32. Therefore, in the process of the second movable member 32 moving along the height direction of the horizontal grinder 100, the second movable member 32 drives the grinder 2 to move along the height direction of the horizontal grinder 100, that is, the effect of the grinder 2 moving along the height direction of the horizontal grinder 100 is achieved.

[0039] It is worth noting that, since the bed 1 is provided with two supports 11 spaced apart in the width direction of the bed 1 for supporting the displacement drive mechanism 3, the displacement drive mechanism 3 and the bed 1 are combined to form a "gantry structure". It should be understood that: "The gantry structure is composed of two columns and a crossbeam, forming a stable frame that can withstand large loads. For example, in a gantry machining center, this structure can easily cope with the cutting force generated during the machining of large and heavy parts, ensuring the stability of the machining process.", and "The symmetry and integrity of the gantry structure enable each part to cooperate with the force when subjected to external force to reduce deformation." Therefore, the design of the "gantry structure" formed by the combination of the displacement drive mechanism 3 and the bed 1 is also conducive to ensuring the movement stability of the displacement drive mechanism 3, so as to improve the movement accuracy of the displacement drive mechanism 3. For the horizontal grinder 100, this is conducive to improving the machining accuracy of the horizontal grinder 100.

[0040] It is also worth noting that in the related art, the "two columns" and the "crossbeam" in the "gantry structure" are an integrated structure, while in the horizontal grinder 100 of the present application, the "gantry structure" is formed by the combination of a displacement drive mechanism 3 and a bed 1, the "two columns" in the "gantry structure" are composed of two supports 11 in the bed 1, and the "crossbeam" in the "gantry structure" is composed of the displacement drive mechanism 3.

[0041] Because during the use of the horizontal grinder 100, the bed 1 is in a stationary state, while the displacement drive mechanism 3 is in a moving state. Therefore, for the horizontal grinder 100 of the present application, based on the "gantry structure" formed by the combination of the displacement drive mechanism 3 and the bed 1, the "two columns" in the "gantry structure" are composed of static supports 11, and the displacement drive mechanism 3 to be moved is composed of the "crossbeam" in the "gantry structure". Therefore, in the horizontal grinder 100 of the present application, the "two columns" in the "gantry structure" are composed of two supports 11 in the bed 1, and the "crossbeam" in the "gantry structure" is composed of the displacement drive mechanism 3, so that the overall mass of the displacement drive mechanism 3 is reduced on the basis of the "gantry structure" formed by the combination of the displacement drive mechanism 3 and the bed 1. In this way, during the movement of the displacement drive mechanism 3, the inertia force of the displacement drive mechanism 3 can be effectively reduced, and the anti-eccentric load requirement for the sliding mechanism arranged between the displacement drive mechanism 3 and the bed 1 is relatively small. At the same time, the wear of the sliding mechanism arranged between the displacement drive mechanism 3 and the bed 1 can also be reduced, so as to improve the movement accuracy of the displacement drive mechanism 3, thereby improving the machining accuracy of the horizontal grinder 100, and the machining accuracy under the long-term use of the horizontal grinder 100, thereby reducing the maintenance cost of the horizontal grinder 100.

[0042] As shown in FIG. 1 and FIG. 4 , the object-placing turntable mechanism 4 is fixedly matched with the bed 1, and it can also be understood that the object-placing turntable mechanism 4 and the bed 1 are in a relatively static state. In this application, the grinder 2 is driven to move by the displacement drive mechanism 3 so that the grinder 2 moves to a suitable position to grind the workpiece placed in the object-placing turntable mechanism 4. In this way, the processing accuracy of the horizontal grinder 100 can be improved.

[0043] For example, since the displacement drive mechanism 3 has high motion accuracy, the displacement drive mechanism 3 is used to drive the grinder 2 relative to the object turntable mechanism 4, so that during the processing, the grinder 2 can reach the preset position more accurately, thereby achieving the effect of improving the processing accuracy of the horizontal grinder 100.

[0044] As shown in FIG. 4 , the object placement turntable mechanism 4 includes an inclination adjustment portion 41 and a rotating object placement portion 42. The rotating object placement portion 42 is assembled on the inclination adjustment portion 41. The inclination adjustment portion 41 is used to adjust the inclination angle of the rotating object placement portion 42 so that the workpiece disposed on the rotating object placement portion 42 can be in a horizontal state or an inclined state, thereby changing the contact angle between the workpiece and the grinding head 20 of the grinder 2, so that the workpiece can be processed by the horizontal grinder 100 to form a variety of structural forms, so that the horizontal grinder 100 has more functional characteristics.

[0045] Exemplarily, when the inclination adjustment portion 41 is in a horizontal state, the rotating placement portion 42 provided on the inclination adjustment portion 41 is also in a horizontal state. During the process of the grinder 2 grinding the workpiece, the rotating placement portion 42 is used to drive the rotation of the rotating placement portion 42, so that the grinder 2 can process the workpiece into a stepped structure, such as a convex stepped structure and / or a concave stepped structure.

[0046] In addition, when the inclination adjustment part 41 is in an inclined state, the rotating storage part 42 provided on the inclination adjustment part 41 is synchronously in an inclined state, so that during the grinding process of the workpiece by the grinder 2, the workpiece can be processed to form a surface structure with a concave middle portion and / or a surface structure with a convex middle portion, for example, the inner edge of the circular workpiece is processed to form an inwardly concave annular inclined surface. Therefore, the storage turntable mechanism 4 in the horizontal grinder 100 of the present application is provided with an inclination adjustment part 41, which can adjust the inclination angle of the workpiece so that the workpiece can be processed into a variety of structural forms, so that the horizontal grinder 100 has more functional characteristics.

[0047] In summary, the horizontal grinder 100 according to the present application can achieve the effect of processing the workpiece into various structural forms, and at the same time can meet the requirements of high precision.

[0048] In some embodiments of the present application, the bed 1 is made of marble. It should be understood that "marble has the properties of low internal stress, wear resistance, corrosion resistance, high stability, etc." In this way, the bed 1 will not be affected by factors such as ambient temperature, stress, conductivity, magnetism, pH, etc. during long-term use, which is conducive to ensuring the processing accuracy of the horizontal grinder 100 under long-term use and reducing the maintenance cost of the horizontal grinder 100. In addition, during the process of the horizontal grinder 100 processing the workpiece, when grinding the workpiece of superhard material, the bed 1 is prone to vibration due to the large grinding force. Since the bed 1 is made of marble, it can effectively suppress vibration and ensure the processing accuracy and surface quality of the workpiece. In addition, the bed 1 is made of marble, which will not cause the bed 1 to deform under long-term use, which is conducive to extending the service life of the horizontal grinder 100.

[0049] In some embodiments of the present application, referring to FIG. 2 and FIG. 3 , the horizontal grinder 100 further includes a hydrostatic guide rail 51 and a hydrostatic slider 52. The upper end surface of the support 11 is formed with a slide groove 54 that is recessed toward the inside, and the hydrostatic guide rail 51 is assembled in the slide groove 54 of the support 11 to define a sliding space 53 together with the support 11. It should be supplemented that the slide groove 54 is extended along the length direction of the support 11, that is, the sliding space 53 is extended along the length direction of the horizontal grinder 100.

[0050] The static pressure slider 52 is movably arranged in the sliding space 53. Since the sliding space 53 is extended along the length direction of the horizontal grinder 100, the static pressure slider 52 can move in the sliding space 53 along the length direction of the horizontal grinder 100. And since the first moving member 31 in the displacement drive mechanism 3 is fixedly matched with the static pressure slider 52, the displacement drive mechanism 3 is moved along the length direction of the horizontal grinder 100 through the static pressure slider 52. It should be understood that when the static pressure slider 52 is arranged in the sliding space 53, there is an oil film between the static pressure slider 52 and the upper interface and the lower interface of the sliding space 53, which is in a pure liquid friction state, and the friction coefficient is extremely low, which can achieve extremely high positioning accuracy and repeated positioning accuracy, and can meet the ultra-precision machining and measurement and other work with extremely high precision requirements. Since the oil film has good damping characteristics, it can effectively absorb and attenuate vibration, reduce the impact of vibration, improve machining accuracy and surface quality, and also reduce the noise of the displacement drive mechanism 3 during operation, and improve the working environment. Therefore, according to the horizontal grinder 100 of the present application, the sliding cooperation between the displacement drive mechanism 3 and the bed 1 is achieved through the static pressure slider 52, which can ensure the movement accuracy of the displacement drive mechanism 3 and further improve the processing accuracy of the horizontal grinder 100.

[0051] It is also worth mentioning that when factors such as changes in load cause the gap between the hydrostatic slider 52 and the upper interface or the lower interface of the sliding space 53 to change, the hydrostatic system can automatically adjust the oil pressure so that the hydrostatic slider 52 always remains in a suspended state, maintaining a stable oil film thickness, and ensuring that the accuracy and performance of the displacement drive mechanism 3 are not affected.

[0052] In addition, in some embodiments of the present application, the multiple static pressure sliders 52 disposed in the sliding space 53 are specifically designed based on an anti-overturning design method of a sliding assembly, so that the static pressure sliders 52 have the ability to resist eccentric loads, so that the displacement drive mechanism 3 can always maintain a horizontal state. This is conducive to ensuring the movement accuracy of the displacement drive mechanism 3, thereby improving the processing accuracy of the horizontal grinder 100.

[0053] What needs to be understood about the specific design of the anti-overturning design method of the sliding component is: "The design method is based on a slider that adopts a plane gap throttling feedback adaptive adjustment model, by obtaining the baseline overturning component force value and variable overturning component force value of the slider, and selecting the quantitative data in the sliding component and the baseline size parameter group and variable size parameter group of the slider. Based on the above steps, the first spacing difference and the second spacing difference of the slider are calculated and obtained, and the target size parameter group is selected from multiple variable size parameter groups by comparing the first spacing difference and the second spacing difference. The target size parameter group is the target size parameter group of the slider, and finally the anti-overturning slider is designed and generated based on the target size parameter group. Therefore, the above-mentioned anti-overturning design method of the sliding component can enable each anti-overturning slider to independently and adaptively adjust the oil film stiffness according to the corresponding load to achieve anti-overturning capability. In this way, for a precision machine tool equipped with a sliding component according to the design method of the present application, the precision machine tool has higher precision.".

[0054] In some embodiments of the present application, referring to FIG. 4 and FIG. 5 , the inclination adjustment portion 41 includes an assembly base 411 and a pivot shaft 412, and the assembly base 411 is rotatably matched with the pivot shaft 412 so that the assembly base 411 is suitable for axial rotation around the pivot shaft 412, thereby enabling the assembly base 411 to rotate from a horizontal state to an inclined state, and to be reset from an inclined state to a horizontal state. In this way, the rotating storage portion 42 assembled on the assembly base 411 can also move from a horizontal state to an inclined state, and from an inclined state to a horizontal state, so as to achieve the effect of adjusting the contact angle between the workpiece placed on the rotating storage portion 42 and the grinding head 20 of the grinder 2. In addition, the inclination adjustment portion 41 also includes an angle locking member 413, which is used to lock the inclination angle of the assembly base 411 so that the assembly base 411 can be maintained at a fixed inclination angle.

[0055] For example, referring to FIG. 4 , in some embodiments of the present application, taking the case where the number of pivot shaft bodies 412 provided in the tilt adjustment portion 41 is two, the two pivot shaft bodies 412 are coaxially arranged and symmetrically arranged on both sides of the assembly base 411, so that during the rotation of the assembly base 411, the assembly base 411 rotates around the axial direction of the two pivot shaft bodies 412. However, the present application is not limited thereto, and the number of pivot shaft bodies 412 provided in the tilt adjustment portion 41 may also be one, and when the number of pivot shaft bodies 412 is one, the pivot shaft body 412 may cross the entire assembly base 411, so that both ends of the pivot shaft body 412 are exposed from the assembly base 411.

[0056] Referring to FIG. 4 and FIG. 5 , in some embodiments of the present application, the angle locking member 413 includes a support screw 413a, a first locking nut 413b and a second locking nut 413c. The support screw 413a is movably arranged in the assembly base 411, and in the axial direction of the support screw 413a, the assembly base 411 is sandwiched between the first locking nut 413b and the second locking nut 413c. Since the first locking nut 413b and the second locking nut 413c are both threadedly engaged with the support screw 413a to limit the relative position of the assembly base 411 and the support screw 413a in the axial direction of the support screw 413a, the angle locking member 413 can lock the tilt angle of the assembly base 411, so that the assembly base 411 is kept at a fixed tilt angle.

[0057] In one embodiment of the present application, the first locking nut 413b and the second locking nut 413c are both precision nuts. It should be understood that: "A precision nut is a component used for mechanical connection, which is used in conjunction with a bolt or a screw to achieve the functions of fastening and connection through the meshing of threads. Compared with ordinary nuts, precision nuts have higher requirements in terms of dimensional accuracy, manufacturing tolerance, thread quality, etc., and can provide more precise fastening force and position accuracy." Therefore, according to the horizontal grinder 100 of the present application, since the first locking nut 413b and the second locking nut 413c are both precision nuts, this can effectively ensure the accuracy of the inclination angle of the assembly base 411, and also has long-term effectiveness.

[0058] It should be supplemented that, in some of the above-mentioned embodiments, the angle locking member 413 includes a support screw 413a, a first locking nut 413b and a second locking nut 413c. However, the present application is not limited thereto. In other embodiments of the present application, the angle locking member 413 may include a threaded screw and a screw nut, wherein the screw nut is assembled on the assembly base 411, and the screw nut is driven to rotate so that the screw nut moves along the axial direction of the threaded screw. During the process of the screw nut moving along the axial direction of the threaded screw, the screw nut can drive the assembly base 411 to move so that the inclination angle of the assembly base 411 changes. Since the threaded screw and the screw nut have self-locking characteristics, the inclination angle of the assembly base 411 can also be locked.

[0059] Referring to Figure 5, in some embodiments of the present application, the rotating storage portion 42 includes a torque motor 421 and a storage platform 422, and the output shaft 4210 of the torque motor 421 is fixedly connected to the storage platform 422, so that when the torque motor 421 drives the output shaft 4210 to rotate, the output shaft 4210 drives the storage platform 422 to rotate, thereby achieving the effect of the torque motor 421 driving the storage platform 422 to rotate.

[0060] The rotating storage part 42 also includes a hydrostatic bearing 423. Referring to FIG. 5 , an assembly space 4110 is provided in the assembly base 411, and the torque motor 421 is arranged in the assembly space 4110, that is, the torque motor 421 is assembled in the assembly base 411. The hydrostatic bearing 423 is sleeved on the output shaft 4210, so that in the radial direction of the output shaft 4210, the hydrostatic bearing 423 is arranged between the output shaft 4210 and the assembly base 411, so that during the rotation of the output shaft 4210, the smoothness of the rotation of the output shaft 4210 is ensured, and the high-precision rotation of the output shaft 4210 is achieved, so as to effectively control the precision of the workpiece placed on the rotating storage part 42.

[0061] 5, the assembly base 411 includes a base body 411a and an end cover 411b, wherein a through hole is provided in the base body 411a, and the end cover 411b is covered at one end of the through hole to define an assembly space 4110 in the assembly base 411. The end cover 411b is fixedly assembled to the base body 411a, so that the end cover 411b can support the rotating storage portion 42 provided above the end cover 411b.

[0062] It is important to understand that: "Hydrostatic bearings are a type of sliding bearing. They use externally supplied pressurized oil to form a hydrostatic load-bearing oil film in the oil chamber of the bearing, completely separating the journal from the bearing surface, and allowing the journal to operate on the hydrostatic oil film. The working principle of this bearing is based on fluid hydrostatic lubrication, that is, the pressure of the lubricating film is maintained by an external pressure source.", "Hydrostatic bearings can provide extremely high rotational accuracy. Since the journal is suspended on the hydrostatic oil film, direct contact between the journal and the bearing surface is avoided, reducing the effects of friction and wear on accuracy.", "The oil film stiffness of the hydrostatic bearing can be controlled by adjusting the oil supply pressure and the parameters of the throttle. It can withstand large radial and axial loads, and can keep the journal position relatively stable when the load changes.", "Because the journal and the bearing are separated by a hydrostatic oil film, the friction coefficient is very small and almost negligible. This not only reduces energy loss, but also reduces wear and greatly extends the service life of the bearing.".

[0063] Referring to FIG. 4 and FIG. 5 , in some embodiments of the present application, the storage platform 422 includes an assembly connection portion 422a and a magnetic platform portion 422b, wherein the assembly connection portion 422a is fixedly connected to the output shaft 4210, and the magnetic platform portion 422b is fixedly assembled on the side of the assembly connection portion 422a away from the output shaft 4210. Since the magnetic platform portion 422b is fixedly connected to the assembly connection portion 422a, the torque motor 421 can drive the output shaft 4210 and the assembly connection portion 422a to rotate synchronously. The magnetic platform portion 422b is used to place the platform, so that for a workpiece made of metal material, the workpiece is adsorbed on the magnetic platform portion 422b by magnetic force to achieve the effect of firmly fixing the workpiece on the magnetic platform portion 422b, and there is no need to set a clamp for fixing the workpiece, so that a larger workpiece can be set in a limited area. It is also worth noting that, since there is no need to provide a fixture for fixing the workpiece, there are no excessive requirements on the shape of the workpiece placed on the magnetic platform portion 422 b , thereby improving the versatility of the horizontal grinder 100 .

[0064] Referring to Figures 1 and 2, in some embodiments of the present application, the bed 1 also includes a base 12. In the width direction of the base 12 (i.e., the width direction of the horizontal grinder 100), two supports 11 are respectively fixed on both sides of the base 12 so that the base 12 is fixedly connected to the two supports 11, which can also improve the structural stability of the two supports 11.

[0065] The two supports 11 are combined with the base 12 to define an operating space 10 in the bed 1, so that when the displacement drive mechanism 3 is assembled on the bed 1, part of the structure of the second movable member 32 in the displacement drive mechanism 3 can be located in the operating space 10, and the grinder 2 assembled on the second movable member 32 is located in the operating space 10, and part of the structure of the object turntable mechanism 4 is also located in the operating space 10, so that the overall structure of the horizontal grinder 100 is more compact, so that the overall structure of the horizontal grinder 100 is smaller, and the horizontal grinder 100 occupies less space.

[0066] In some embodiments, as shown in FIG. 2 , the bed 1 further includes a side plate 13, which is disposed near the rear side of the bed in the length direction of the bed 1 and is connected between the two supports 11 in the width direction of the bed 1 to further improve the structural stability of the bed 1. The side plate 13 also further defines an operating space 10 in the bed 1.

[0067] As shown in combination with FIG. 4 and FIG. 5 , in some embodiments of the present application, the base 12 is provided with an avoidance groove 120, the opening of the avoidance groove 120 is arranged toward the storage turntable mechanism 4, and the avoidance groove 120 is used to avoid a part of the structure of the storage turntable mechanism 4, so as to avoid the bottom of the storage turntable mechanism 4 from colliding with the upper end surface of the base 12. It is also worth noting that, referring to FIG. 5 , since the base 12 is provided with an avoidance groove 120 for avoiding a part of the structure of the storage turntable mechanism 4, the torque motor 421 in the storage turntable mechanism 4 can be designed as a "sinking type", so that when the height of the operating space 10 in the horizontal grinder 100 remains unchanged, the distance between the upper end surface of the storage turntable mechanism 4 and the upper boundary of the operating space 10 is large, so as to avoid the storage turntable mechanism 4 from occupying more space in the operating space 10. In this way, the overall height dimension of the horizontal grinder 100 can be reduced.

[0068] Referring to FIG. 1 , in some embodiments of the present application, the horizontal grinding machine 100 may further include a trimming mechanism 6, which is used to trim the shape and surface condition of the grinding head 20 of the grinder 2. During the grinding process, the grinding head 20 may lose its original precision and cutting performance due to wear, blockage, etc. The trimming mechanism 6 trims the grinding head 20 to restore its sharp cutting edge and correct geometric shape, thereby ensuring the grinding quality.

[0069] 1 , the knife trimming mechanism 6 is mounted on the base 12 of the bed 1 and is located in the operating space 10, and in the length direction of the horizontal grinder 100, the knife trimming mechanism 6 and the grinding head 20 of the grinder 2 are arranged correspondingly, so that the grinder 2 is driven along the length direction of the horizontal grinder 100 by the displacement driving mechanism 3, so that in the height direction of the horizontal grinder 100, the grinder 2 is located above the knife trimming mechanism 6, and then the second moving member 32 can be used to drive the grinder 2 along the height direction of the horizontal grinder 100 to cooperate with the knife trimming mechanism 6, so that the knife trimming mechanism 6 can be used to trim the grinding head 20.
