Technical Field

[0001] This application relates to the technical field of machining machine tools, and particularly to a shim and a processing device. Background Art

[0002] The equipment manufacturing industry has put forward higher requirements for machine tool mechanisms in terms of speed, acceleration, accuracy, and stability in industrial applications.

[0003] Among them, the foundation is the basis for ensuring the accuracy of the machine tool. The shim structure is the intermediate link between the machine tool and the foundation, which can adjust the level of the machine tool, correct and compensate for the accuracy errors generated during the manufacturing process of the equipment and the dimensional deviations caused by the construction of the equipment foundation, and is the basis for ensuring the stable accuracy of the machine tool.

[0004] However, the adjustment accuracy of the existing shim structure is relatively low and cannot meet the requirements of high-precision operations. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0047] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0048] In this application, unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature is at a higher level than the second feature in terms of horizontal height. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature is at a lower level than the second feature in terms of horizontal height.

[0050] As Figure 1 and Figure 2 shown, it is defined that the length direction of the shim 1000 is parallel to the second direction M, the width direction of the shim 1000 is parallel to the third direction N, and the height direction of the shim 1000 is parallel to the first direction L. It can be understood that the above definitions are only for facilitating the understanding of the relative positional relationship of each part structure in the shim 1000 and should not be construed as a limitation to this application.

[0051] As Figure 1 shown, in the embodiment, a shim 1000 is provided, which can be disposed between the machine tool 2000 and the foundation (not shown in the figure) for providing support and leveling functions for the machine tool 2000.

[0052] Combined with Figure 2 and Figure 4 , the shim 1000 includes a base assembly 100, a first slider 200, a spacer 300 and a first limiting member 500. Among them, the base assembly 100 is configured with an assembly cavity 101 and an opening structure 102 communicating with the assembly cavity 101.

[0053] The first slider 200 is slidably mounted in the assembly cavity 101 along the first direction L. In addition, a limiting groove 210 is provided on the side of the first slider 200 close to the opening structure 102, and a first spherical surface 211 is provided at the bottom of the limiting groove 210.

[0054] The cushion block 300 is arranged in the limiting groove 210. A second spherical surface 310 is provided on the side of the cushion block 300 close to the groove bottom, and the second spherical surface 310 can be slidably attached to the first spherical surface 211. A flat surface 320 is provided on the side of the cushion block 300 away from the first spherical surface 211, which can be used to support the machine tool 2000.

[0055] The first limiting member 500 is connected between the cushion block 300 and the first slider 200, and can be used to limit the cushion block 300 from detaching from the first slider 200. That is, to prevent the cushion block 300 from separating from the first slider 200 randomly.

[0056] During the use process, a soleplate 1000 can be respectively arranged at the four corner positions of the machine tool 2000 to support the machine tool 2000. When a certain corner position of the machine tool 2000 is too low or too high, the height of the corresponding position of the machine tool 2000 can be adjusted by adjusting the soleplate 1000 at this position to level the machine tool 2000. Specifically, the first slider 200 can be slid along the first direction L to adjust the position of the first slider 200 in the height direction of the soleplate 1000, that is, to adjust the height of the first slider 200. The first slider 200 can drive the cushion block 300 to move synchronously to adjust the height of the cushion block 300, and further the height of the corresponding position of the machine tool 2000 can be adjusted, improving the overall horizontal accuracy of the machine tool 2000.

[0057] During this process, the cushion block 300 and the first slider 200 are in spherical surface fit and can move relatively. For example, when the machining accuracy of the bottom surface of the machine tool 2000 is low or the flatness of the foundation is low, the relative position between the two spherical surfaces can be adjusted automatically, and through the adjustment of the relative position between the spherical surfaces, it is ensured that the machine tool 2000 is always in contact with the flat surface 320 in the cushion block 300, that is, it is ensured that there is a large contact area between the machine tool 2000 and the soleplate 1000, with better load-bearing capacity. At the same time, the adjustment accuracy of the soleplate 1000 will not be reduced due to wear.

[0058] Such as Figure 1 and Figure 2As shown, in some embodiments, the base assembly 100 may include a base 110 and two side plates 120. Among them, the base 110 has a U-shaped structure and is configured with two opposite notches. The two side plates 120 can be correspondingly arranged at the two notch positions of the base 110 to close the two notches of the base 110. Correspondingly, the assembly cavity 101 can be surrounded by the cooperation of the base 110 and the two side plates 120. In some embodiments, the side plate 120 can be parallel to the first direction L and the second direction M at the same time. The base 110 and the side plate 120 can be fixedly connected by screws 700.

[0059] In some other embodiments, the side plate 120 and the base 110 can also be fixedly connected by welding or snap connection.

[0060] In some other embodiments, the base assembly 100 may include a base 110. The base 110 may have a frame structure with a closed perimeter and have four side walls 112. The assembly cavity 101 may be opened in the base 110.

[0061] As Figure 2 shown, the shim 1000 further includes a second slider 400. The second slider 400 is arranged in the assembly cavity 101 and is located on the side of the first slider 200 away from the spacer 300. In the embodiment, the second slider 400, the first slider 200 and the spacer 300 can be stacked in sequence, and the second slider 400 can be placed on the bottom plate 111 of the base 110 to provide corresponding support.

[0062] In addition, the second slider 400 can be slidably arranged in the assembly cavity 101 along the second direction M. The sliding direction of the second slider 400 can be perpendicular to the sliding direction of the first slider 200.

[0063] It can be understood that in the second direction M, the size of the assembly cavity 101 is larger than the size of the second slider 400, which can provide a sliding space for the second slider 400. In addition, in the third direction N, the size of the second slider 400 can be smaller than and close to the size of the assembly cavity 101, and there is a gap between the second slider 400 and the two opposite inner walls (i.e., the two side plates 120) of the assembly cavity 101. On the one hand, it can ensure that the second slider 400 can slide smoothly in the assembly cavity 101, reduce the sliding resistance, so that the operator can easily adjust the height of the corresponding position of the machine tool 2000. On the other hand, the side plate 120 can also provide a guiding function for the movement of the second slider 400, reducing the possibility of the second slider 400 being skewed and causing jamming or jamming.

[0064] As Figure 1 and Figure 2As shown, in the second direction M, the size of the first slider 200 is smaller than and close to the size of the assembly cavity 101, and accordingly, a gap is left between the first slider 200 and the inner wall of the corresponding position of the assembly cavity 101. In the third direction N, the size of the first slider 200 is smaller than and close to the size of the assembly cavity 101, and accordingly, a gap is left between the first slider 200 and the inner wall of the corresponding position of the assembly cavity 101. On the one hand, it can ensure that the first slider 200 can slide smoothly relative to the base assembly 100, reduce the resistance of the first slider 200 during the sliding process, so that the operator can easily adjust the height of the corresponding position of the machine tool 2000. On the other hand, the base assembly 100 can provide a guiding function for the sliding of the first slider 200, reducing the probability of the first slider 200 being skewed and stuck or stuck.

[0065] Combined with Figure 5 In some embodiments, a first inclined surface 410 is disposed on a side of the second slider 400 close to the first slider 200. A second inclined surface 220 is disposed on a side of the first slider 200 close to the second slider 400. The second inclined surface 220 is parallel to the first inclined surface 410, and the second inclined surface 220 and the first inclined surface 410 are slidably matched. In the second direction M, the first inclined surface 410 can be gradually inclined from one side to the other side thereof, away from the cushion block 300.

[0066] Therefore, when the second slider 400 slides along the second direction M, it can drive the first slider 200 to slide along the first direction L, that is, the height adjustment of the first slider 200 is achieved.

[0067] like Figure 2 , Figure 3 and Figure 5 As shown, the washer 1000 further includes a driving assembly 600. The driving assembly 600 is connected to the second slider 400 and can be used to drive the second slider 400 to slide along the second direction M.

[0068] In some embodiments, the driving assembly 600 may include a second connecting rod 611, a second limiting edge 612, and a second limiting member 620. The second connecting rod 611 may be arranged along the second direction M through the side wall 112 on one side of the base 110, and the second connecting rod 611 may rotate relative to the side wall 112. In addition, one end of the second connecting rod 611 located in the assembly cavity 101 may be threadedly connected to the first slider 200.

[0069] The second limiting edge 612 is arranged at one end of the second connecting rod 611 away from the second slider 400 and abuts against the side of the base 110 away from the assembly cavity 101. It can be understood that the second limiting edge 612 abuts against the side of the side wall 112 through which the second connecting rod 611 passes away from the assembly cavity 101. In the embodiment, the second limiting edge 612 and the second connecting rod 611 can be of an integral structure, that is, a bolt structure can be formed.

[0070] The second limiting member 620 can be connected to one end of the second connecting rod 611 close to the second limiting edge 612 and abuts against the side of the side wall 112 through which the second connecting rod 611 passes close to the assembly cavity 101. Under the combined action of the second limiting edge 612 and the second limiting member 620, the axial movement of the second connecting rod 611 can be restricted, that is, the second connecting rod 611 can only rotate relative to the base 110 and does not perform a sliding action.

[0071] Thus, when the height of the corresponding position of the machine tool 2000 needs to be adjusted, the second limiting edge 612 can be rotated by a wrench, and the second connecting rod 611 is driven to rotate under the action of the second limiting edge 612. When the second connecting rod 611 rotates, due to the limiting action of the first slider 200 and the base 110 on the second slider 400, the second slider 400 can be prevented from rotating synchronously with the second connecting rod 611. Furthermore, under the thread matching action of the second slider 400 and the second connecting rod 611, the second slider 400 can be driven to slide along the second direction M. When the second slider 400 slides along the second direction M, the first slider 200 and the cushion block 300 can be successively driven to lift and lower along the first direction L to achieve high-precision adjustment of the height of the corresponding position of the machine tool 2000.

[0072] In some embodiments, the second limiting member 620 can include a retaining ring 621. The retaining ring 621 is arranged around the circumference of the second connecting rod 611 and is fixedly connected to the second connecting rod 611. And the retaining ring 621 can abut against the side of the side wall 112 through which the second connecting rod 611 passes close to the assembly cavity 101, that is, the inner wall of the assembly cavity 101.

[0073] In some embodiments, the second limiting member 620 further includes a pin 622. The pin 622 can pass through the retaining ring 621 and the second connecting rod 611, and the pin 622 is tightly fitted with the retaining ring 621 and the second connecting rod 611 respectively. Thus, the fixed connection between the retaining ring 621 and the second connecting rod 611 can be realized. It can be understood that a first assembly hole 6211 for inserting the pin 622 can be formed in the retaining ring 621. A second assembly hole 6221 coaxial with and communicating with the first assembly hole 6211 can be formed in the second connecting rod 611, and the pin 622 can be inserted into the first assembly hole 6211 and the second assembly hole 6221. One end of the first assembly hole 6211 close to the opening structure 102 can be configured as a trapezoidal structure to prevent the pin 622 from disengaging from the retaining ring 621 randomly. In addition, the cross-section of the pin 622 along the axial direction can be in a trapezoidal structure, which is beneficial to realizing the tight fit between the pin 622 and the inner walls of the first assembly hole 6211 and the second assembly hole 6221.

[0074] In other embodiments, a clamping groove can be formed on the circumferential side of the second connecting rod 611, and the retaining ring 621 can be clamped in the clamping groove to realize the fixed connection between the retaining ring 621 and the second connecting rod 611.

[0075] In other embodiments, the driving assembly 600 can be selected from structures such as an electric cylinder, a linear motor, a cylinder, etc., and the output shaft of the driving assembly 600 can be parallel to the second direction M. The second slider 400 is connected to the output shaft of the driving assembly 600, and the driving assembly 600 can directly pull the second slider 400 to slide along the second direction M.

[0076] In other embodiments, the second slider 400 and the driving assembly 600 are not excluded from being replaced by a driving member, and the driving member can directly drive the first slider 200 to slide along the first direction L to realize height adjustment. Among them, the driving member can be selected from structures such as a hydraulic cylinder, a cylinder, etc.

[0077] As Figure 2 、 Figure 4 and Figure 5 shown, the first limiting member 500 can include a first connecting rod 510 and a first limiting edge 520 located at one end of the first connecting rod 510. The first connecting rod 510 can pass through the cushion block 300 and the first slider 200 in sequence along the first direction L and is in threaded fit connection with the first slider 200. The first limiting edge 520 can be located on the side of the cushion block 300 away from the first slider 200. In the embodiment, the first limiting member 500 can be a screw or bolt structure.

[0078] In the embodiment, a through hole 330 extending along the first direction L is formed in the cushion block 300. The first connecting rod 510 can pass through the through hole 330, and a gap is provided between the first connecting rod 510 and the inner wall of the through hole 330. Thus, the cushion block 300 is allowed to move relative to the first connecting rod 510, and further, relative movement along the spherical surface between the cushion block 300 and the first slider 200 is allowed. During the adjustment process, the movement of the cushion block 300 relative to the first slider 200 can compensate for the unevenness of the bottom surface of the machine tool 2000 and the unevenness of the foundation. In addition, a sunk groove 340 is formed on one side of the cushion block 300 away from the first slider 200. The first limiting edge 520 is received in the sunk groove 340, and a gap is provided between the first limiting edge 520 and the inner wall of the sunk groove 340. On the one hand, it can ensure the smooth movement of the cushion block 300 relative to the first slider 200. On the other hand, it can also reduce the resistance during the movement of the cushion block 300, save manpower, and facilitate the operation of the operator.

[0079] In the embodiment, the outer diameter of the first limiting edge 520 is larger than the inner diameter of the through hole 330 near the sunk groove 340. Thus, the cushion block 300 can be prevented from completely detaching from the first slider 200.

[0080] When installing and debugging the machine tool 2000, the cushion blocks 300 in each shim 1000 can be first adjusted to the lowest height and placed at the corresponding positions under the machine tool 2000. When the flatness of the foundation is greater than 4 mm, an adjusting pad (not shown in the figure) can be added under the shim 1000. Subsequently, the flatness of the machine tool 2000 can be measured. When a certain position of the machine tool 2000 is too low, the second limiting edge 612 can be rotated by a wrench to drive the second connecting rod 611 to rotate. Thus, the second slider can be driven to slide along the second direction M to drive the first slider 200 and the cushion block 300 to move up and down along the first direction L, so as to adjust the height of the corresponding position of the machine tool 2000.

[0081] In summary, the shim 1000 provided in the present application can achieve high-precision adjustment of the height of the machine tool 2000. The unevenness of the bottom surface of the machine tool 2000 and the unevenness of the foundation can be absorbed by the relative movement between the two spherical surfaces, that is, the relative movement between the cushion block 300 and the first slider 200. At the same time, the accuracy change caused by wear can be compensated, and it is ensured that the shim 1000 maintains a high adjustment accuracy.

[0082] In the embodiment, a processing device is further provided, including the machine tool 2000 and the shim 1000 provided in the embodiment. The shim 1000 can be disposed below the corresponding position of the machine tool 2000 and between the machine tool 2000 and the foundation. Thus, the height of the corresponding position of the machine tool 2000 can be adjusted by the shim 1000, and high-precision adjustment can be achieved.
