[0038] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0040] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0041] Please refer to Figure 1 , Figure 1 The schematic diagram of the structure of a grinding auxiliary device 01 provided in an embodiment of the present application. The grinding auxiliary device 01 comprises: a reference module 10, a sample module 20, a mounting assembly 30 and a transmission assembly 40;

[0042] The reference module 10 is provided with a receiving through hole 101 in a first direction;

[0043] The sample lower surface of the sample module 20 is parallel to the reference lower surface of the reference module 10, and the sample lower surface and the reference lower surface are respectively perpendicular to the opening direction of the receiving through hole 101; the sample module 20 is configured to be movably received in the receiving through hole 101 along the first direction;

[0044] The mounting assembly 30 is configured to fix the fixed support 401 of the transmission assembly 40 on the reference module 10, and the transmission screw 402 of the transmission assembly 40 is perpendicular to the lower surface of the sample;

[0045] The transmission assembly 40 is configured to push the sample module 20 to move along the first direction in the accommodating through hole 101 based on the transmission screw 402 , and to fix the transmission screw 402 at a preset grinding position based on the fastening structure 403 of the transmission assembly 40 .

[0046] Among them, the grinding auxiliary equipment needs to fix the sample to be ground on the lower surface of the sample of the sample module 20 for grinding. The shape of the reference module 10 can be a cylinder, a cuboid or other reasonable shapes, and the shape of the sample module 20 can be a cylinder, a cube, a cuboid or other reasonable shapes. The shape of the sample module 20 can be the same as or different from the shape of the reference module 10. A detachable connector can be used to achieve a fixed connection between the fixed support 401 and the mounting assembly 30, for example, based on threaded holes and screws, or a snap-on connection structure to achieve a fixed connection between the fixed support 401 and the mounting assembly 30; a non-detachable method such as welding can also be used to achieve a fixed connection between the fixed support 401 and the mounting assembly 30. Figure 1 FIG. 2 shows a case where both the reference module 10 and the sample module 20 are cylindrical in shape. Figure 1 Taking the grinding auxiliary device 01 shown as an example, the opening direction (i.e., the first direction) of the receiving through hole 101 is axial, and the lower surface of the sample and the lower surface of the reference are radially arranged planes. The displacement direction of the transmission screw 402 is axial. By moving the transmission screw 402, the sample module 20 can be pushed to move downward in the receiving through hole 101, thereby driving the sample to be ground fixed on the lower surface of the sample to move toward the outside of the reference module 10; and the moving distance of the transmission screw 402 is the same as the moving distance of the sample to be ground. By controlling the moving distance of the transmission screw 402, the grinding thickness can be accurately controlled, thereby improving the control accuracy of the grinding thickness. In addition, since the lower surface of the sample module 20 is parallel to the lower surface of the reference module 10, the flatness of the grinding surface of the sample to be ground can be ensured by grinding the sample to be ground on a flat grinding groove / grinding plate.

[0047] It can be seen that the grinding auxiliary device 01 provided in the embodiment of the present application includes: a reference module 10, a sample module 20, a mounting assembly 30 and a transmission assembly 40; the grinding auxiliary device 01 can push the sample module 20 to move in the first direction in the receiving through hole 101 based on the transmission screw 402, and adjust the grinding depth of the sample to be ground by adjusting the position of the lower surface of the sample, and fix the transmission screw 402 at a preset grinding position based on the fastening structure 403 of the transmission assembly 40 to fix the grinding depth, so as to control the grinding depth of the sample to be ground; and the lower surface of the sample is parallel to the lower surface of the reference, which can ensure the flatness of the grinding surface of the sample to be ground. It solves the technical problems that the existing manual grinding method is prone to uneven grinding surface, and the grinding thickness is difficult to control, and cannot meet the grinding requirements of higher precision.

[0048] In some optional embodiments, the shape of the sample module 20 is consistent with the shape of the opening of the accommodating through hole 101 , and the side surface of the sample module 20 is in contact with the hole wall of the accommodating through hole 101 .

[0049] The opening shape of the receiving through hole 101 can be determined according to the actual shape of the sample module 20. When the sample module 20 is a rectangular parallelepiped, the opening shape of the receiving through hole 101 is also a rectangular parallelepiped, and the cross-sectional size of the sample module is consistent with the cross-sectional size of the receiving through hole 101; the cross-sectional size refers to the cross-sectional size in the direction perpendicular to the opening direction. When the sample module 20 is a column, the opening shape of the receiving through hole 101 is also a column. Figure 1 , the sample module 20 is a column, and the opening shape of the receiving through hole 101 is also a column. Since the shape of the sample module 20 is consistent with the opening shape of the receiving through hole 101, the fitting area between the side surface of the sample module 20 and the hole wall of the receiving through hole 101 can be increased as much as possible, thereby increasing the friction between the sample module 20 and the hole wall of the receiving through hole 101, so as to ensure that the sample module 20 can be better fixed at a designated position in the receiving through hole 101 or move smoothly in the receiving through hole 101, so as to better achieve accurate control of the grinding depth.

[0050] Please refer to Figure 2 , Figure 3 , Figure 2 A schematic diagram of the structure of a reference module 10 provided in an embodiment of the present application is shown in FIG. Figure 3 A schematic diagram of the structure of a sample module 20 provided in an embodiment of the present application.

[0051] In some optional embodiments, a first limiting block 201 is provided at one end of the sample module 20 away from the lower surface of the sample; a first limiting groove 102 connected to the accommodating through hole 101 is opened at one end of the reference module 10 away from the lower surface of the reference; the first limiting block 201 is configured to be movably accommodated in the first limiting groove 102 along the first direction.

[0052] Among them, the thickness of the first limit block 201 is less than the depth of the first limit groove 102; the cross-sectional shape of the first limit block 201 and the first limit groove 102 (the cross section in the direction perpendicular to the opening direction of the accommodating through hole 101) can be the same or different, and the present application does not make specific restrictions on this. The side surface of the first limit block 201 can be fitted with the groove wall of the first limit groove 102 to increase the contact area between the sample module 20 and the accommodating through hole 101. The cross-sectional shapes of the first limit block 201 and the first limit groove 102 can also be different, and the specific shapes of the first limit block 201 and the first limit groove 102 can be adjusted according to the actual application scenario. By setting the first limit block 201 at one end of the sample module 20 away from the lower surface of the sample, and opening the first limit groove 102 at one end of the reference module 10 away from the lower surface of the reference, it is convenient for the operator to more quickly and accurately determine the assembly posture between the sample module 20 and the reference module 10, thereby reducing the difficulty of the grinding operation and improving the actual grinding efficiency.

[0053] In some optional embodiments, a second limit block is further provided at one end of the sample module 20 away from the lower surface of the sample; a second limit groove 103 connected to the accommodating through hole 101 is further provided at one end of the reference module 10 away from the lower surface of the reference; the second limit block is symmetrically arranged with the first limit block 201, and the second limit groove 103 is symmetrically arranged with the first limit groove 102; and the second limit block is configured to be movably accommodated in the second limit groove 103 along the first direction.

[0054] in, Figure 2 The case where the second limiting groove 103 is symmetrically arranged with the first limiting groove 102 is shown in FIG. The thickness of the second limiting block is less than the depth of the second limiting groove; the cross-sectional shape of the second limiting block and the second limiting groove 103 (the cross section in the direction perpendicular to the opening direction of the receiving through hole 101) can be the same or different. The side surface of the second limiting block can be fitted with the groove wall of the second limiting groove to increase the contact area between the sample module 20 and the receiving through hole 101. By symmetrically arranging the first limiting block 201 and the second limiting block at one end of the sample module 20 away from the lower surface of the sample, and symmetrically opening the first limiting groove 102 and the second limiting groove 103 at one end of the reference module 10 away from the lower surface of the reference, it is possible to facilitate the operator to more quickly and accurately determine the assembly posture between the sample module 20 and the reference module 10, while further improving the moving stability of the sample module 20 in the receiving through hole 101.

[0055] In some optional embodiments, the grinding auxiliary equipment 01 also includes: a first elastic member and a second elastic member; one end of the first elastic member is fixedly connected to the first groove bottom 1021 of the first limiting groove 102, and the other end of the first elastic member is configured to contact one end of the first limiting block 201 close to the lower surface; one end of the second elastic member is fixedly connected to the second groove bottom of the second limiting groove 103, and the other end of the second elastic member is configured to contact one end of the second limiting block close to the lower surface.

[0056] The first elastic member and the second elastic member can be implemented by a metal spring or a rubber spring, and the implementation methods of the first elastic member and the second elastic member can be the same, so as to improve the moving stability of the sample module 20 in the receiving through hole 101. After the grinding is completed and the transmission assembly 40 is removed, the sample module 20 can be ejected from the receiving through hole 101 by the first elastic member and the second elastic member, thereby reducing the difficulty of disassembling the sample module 20. In the case where the sample to be ground is fixed on the lower surface of the sample by the wax sealing method, the flexibility of grinding can be improved by disassembling the sample module 20 after the grinding is completed and then removing the sample to be ground from the sample module 20 by the wax melting method.

[0057] Please refer to Figure 4 , Figure 4 A schematic structural diagram of another grinding auxiliary device 01 provided in an embodiment of the present application. Figure 4 The case where the reference module 10 and the sample module 20 are both in the shape of a rectangular parallelepiped is shown.

[0058] In some optional embodiments, the transmission assembly 40 includes a micrometer.

[0059] in, Figure 4 The transmission assembly 40 is also shown as being implemented by a micrometer. In the case where the transmission assembly 40 is implemented by a micrometer, the fixed support 401 can be implemented by the bracket part of the micrometer, the transmission screw 402 can be implemented by the micrometer screw, and the fastening structure 403 can be implemented by the locking device of the micrometer. Since the micrometer has a high measurement accuracy, the micrometer can accurately control the grinding depth during the adjustment process of the grinding depth to meet the grinding requirements with higher accuracy.

[0060] Please refer to Figure 5 , Figure 5 A schematic diagram of the structure of an installation assembly 30 provided in an embodiment of the present application.

[0061] In some optional embodiments, the mounting assembly 30 includes: a mounting panel 301 and a mounting bracket 302 that are fixedly connected; a mounting through hole 3011 is opened on the mounting panel 301, and the opening direction of the mounting through hole 3011 is consistent with the opening direction of the accommodating through hole 101;

[0062] The grinding auxiliary device 01 also includes: a first detachable connecting member and a second detachable connecting member; the mounting bracket 302 is configured to be fixedly mounted on the reference module 10 based on the first detachable connecting member; and the micrometer is configured to be fixedly mounted in the mounting through hole 3011 based on the second detachable connecting member.

[0063] The first detachable connector can be implemented by a screw, a nut or a pin, and the second detachable connector can also be implemented by a screw, a nut or a pin; the implementation methods of the first detachable connector and the second detachable connector can be the same or different. Since the mounting bracket 302 is fixedly mounted on the reference module 10 based on the first detachable connector, and the micrometer is fixedly mounted in the mounting through hole 3011 based on the second detachable connector, that is, the micrometer is fixedly connected to the reference module 10 through a detachable connection method; the flexibility of the grinding auxiliary equipment is improved, and it can adapt to more diverse grinding scenarios.

[0064] In some optional embodiments, the second detachable connector includes: a second fastener; a second fastening hole 3012 is further provided on the mounting panel 301, and the opening direction of the second fastening hole 3012 is perpendicular to the opening direction of the mounting through hole 3011;

[0065] The fixed support 401 of the micrometer is fitted with the inner wall of the mounting through hole 3011 , and the second fastener is configured to be screwed into the second fastening hole 3012 and squeeze the fixed support 401 so that the micrometer is fixedly connected to the mounting assembly 30 .

[0066] The second fastener may be implemented by a screw or a nut, and by screwing the screw or the nut into the second fastening hole 3012 and squeezing the fixed support 401 of the micrometer, a fixed connection between the fixed support 401 and the mounting panel 301 can be achieved, thereby achieving a fixed connection between the micrometer and the mounting assembly 30. By providing the second fastening hole 3012 in the mounting panel 301, a detachable fixed connection between the micrometer and the mounting assembly 30 is achieved based on the second fastener and the second fastening hole 3012, which can reduce the difficulty of installing / disassembling the micrometer and the mounting assembly 30.

[0067] In some optional embodiments, the first detachable connector includes: a first fastener; the reference module 10 is also provided with a first fastening hole 104, and the opening direction of the first fastening hole 104 is consistent with the opening direction of the accommodating through hole 101; the reference lower surface of the reference module 10 is also provided with a mounting groove 105 connected to the first fastening hole 104; a third fastening hole 3021 is provided at one end of the mounting bracket 302 close to the reference module 10; the first fastener is configured to be screwed into the first fastening hole 104 from the mounting groove 105, and screwed into the third fastening hole 3021 through the first fastening hole 104, so as to fix the mounting bracket 302 on the reference module 10.

[0068] Among them, the first fastener can be realized by a screw or a nut. By opening a first fastening hole 104 in the reference module 10, and opening a mounting groove 105 connected to the first fastening hole 104 on the reference lower surface of the reference module 10, the difficulty of installation / disassembly between the mounting bracket 302 and the reference module 10 is reduced. Specifically, in the case of opening the mounting groove 105, the hole depth of the first fastening hole 104 can be reduced, and accordingly, the length of the first fastener used can be shortened, thereby reducing the difficulty of installation / disassembly between the mounting bracket 302 and the reference module 10. It can be understood that when the number of the first fastening holes 104 is two, the number of the mounting grooves 105 opened can also be two, Figure 2 Only one mounting slot 105 is shown as an example.

[0069] In some optional embodiments, the material of the reference module 10 includes: abrasion-resistant material.

[0070] The reference module 10 may be made of a material such as high manganese steel, cast iron, alloy, or other metal material, or abrasion-resistant material such as ceramic or glass. Since the reference module 10 is made of abrasion-resistant material, the wear effect of the actual grinding operation on the reference lower surface of the reference module 10 can be reduced, thereby improving the grinding accuracy and service life of the grinding auxiliary device 01.
