Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] The positional nouns such as “upper”, “lower”, “lateral” and the like in the embodiments of the present application are generally taken with reference to the figures. Figure 1The relative relationship of the orientations shown in the figures is taken as a reference, and these orientation terms are used only for more clearly describing the structure and the relationship between structures, and are not used to describe absolute orientations. When the product is placed in different postures, the orientations may change, for example, "upper" and "lower" may be interchanged.

[0037] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by one of ordinary skill in the art.

[0038] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0039] The present application provides a grinding device, such as Figure 1 As shown in the figure, the grinding device comprises a stage 1, a base 2, a clamping mechanism 3, a supporting mechanism 4 and an adjusting mechanism 5, wherein,

[0040] The stage 1 is installed on the base 2 and can rotate relative to the base 2 around a first axis;

[0041] The clamping mechanism 3 is installed on the supporting mechanism 4 and can move along the first axis relative to the supporting mechanism 4;

[0042] The adjusting mechanism 5 is used to connect the clamping mechanism 3 and the supporting mechanism 4 to adjust the friction force that the clamping mechanism 3 receives when moving;

[0043] The opposite ends of the clamping mechanism 3 along the first axis are respectively provided with a clamping part 31 and a pressing part 32, the clamping part 31 faces the stage 1, and the pressing part 32 is used to fix a weight so that the clamping mechanism 3 bears a pressure along the first axis towards the stage 1.

[0044] It can be understood that the rotating stage 1 can place a sandpaper so that the sandpaper can slide relative to the material on the clamping mechanism 3, so as to grind the material. When the pressing part 32 of the clamping mechanism 3 bears a pressure, it can act on the material through the clamping part 31, which is beneficial to the material to maintain a stable state of being attached to the stage 1 during grinding. The adjusting mechanism 5 adjusts the friction force that the clamping mechanism 3 receives, which is beneficial to the clamping mechanism 3 to move towards the stage 1 under the action of gravity as the material thins during grinding of the material, so as to be beneficial to the material to stably bear the pressure of the pressing part 32 during grinding, and then can be attached to the stage 1, so as to improve the grinding efficiency.

[0045] In the embodiments of the present application, the stage 1 can be directly driven by a motor or driven by a gear transmission to rotate relative to the base 2.

[0046] In the embodiments of the present application, the base 2 is used to support the object table 1 and the supporting mechanism 4, and can have a weight greater than the sum of the weights of the object table 1 and the supporting mechanism 4, so as to reduce the overall gravity center of the grinding device.

[0047] In the embodiments of the present application, the clamping mechanism 3 can exert a pressure on the material, and the pressure direction is perpendicular to the direction of gravity, so that the material can be clamped by the clamping mechanism 3 and subjected to a friction force from the clamping mechanism 3.

[0048] In the embodiments of the present application, the adjusting mechanism 5 can change the position between the supporting mechanism 4 and the clamping mechanism 3 by using the connection relationship between the two, so as to adjust the friction force on the clamping mechanism 3.

[0049] In the embodiments of the present application, the clamping mechanism 3 can be provided with a scale along the direction of the first axis for reference by the staff.

[0050] In some embodiments of the present application, as shown in Figure 1 The cross-sectional area of the pressure applying part 32 is smaller than the cross-sectional area of the clamping mechanism 3.

[0051] It can be understood that the clamping part 31 with a smaller cross-sectional area is beneficial to support the weight, and thus improves the stability of the weight during the material grinding process, so as to improve the grinding efficiency.

[0052] In the embodiments of the present application, the axis of the pressure applying part 32 is collinear with the axis of the clamping mechanism 3.

[0053] In some embodiments of the present application, as shown in Figure 1 The clamping part 31 includes two clamping jaws 311, and the two clamping jaws 311 can relatively approach and move away from each other along a second axis, and the second axis is parallel to the side of the object table 1 facing the clamping jaws 311.

[0054] It can be understood that when the two clamping jaws 311 approach each other, a pair of forces in opposite directions can be applied to the material, so as to clamp the material and form a fit with the object table 1 for grinding; when the two clamping jaws 311 move away from each other, the applied force on the material is removed, and the ground material can be removed.

[0055] In the embodiments of the present application, the two clamping jaws 311 can move independently of each other, and be driven by different motors, or be driven by one motor through a linkage mechanism, so as to approach and move away from each other.

[0056] In some embodiments of the present application, as shown in Figure 2As shown, the support mechanism 4 has a first through hole 401, an axis of the first through hole 401 is parallel to the first axis, the clamping part 31 of the clamping mechanism 3 passes through the first through hole 401 towards the object table 1, and a part of the adjusting mechanism 5 extends into the first through hole 401 for abutting with the clamping mechanism 3.

[0057] It can be understood that the first through hole 401 provides a space for the clamping mechanism 3 to move, so that the clamping mechanism 3 can move towards the object table 1 along the axis direction of the first through hole 401 under the action of gravity, thereby facilitating the grinding of the material. By abutting with the clamping mechanism 3, the adjusting mechanism 5 can generate pressure between the clamping mechanism 3 and the side wall of the first through hole 401, so as to change the frictional force acting on the clamping mechanism 3 during movement. Since the clamping mechanism 3 does not completely fit between the first through hole 401 when located in the first through hole 401, that is, without the adjusting effect of the adjusting mechanism, the clamping mechanism 3 will directly contact the object table 1 through the first through hole 401 under the action of gravity, which may cause the clamping mechanism 3 to swing away from the first axis, which reduces the supporting effect of the clamping mechanism 3. Therefore, the adjusting mechanism 5 can make the clamping mechanism 3 and the support mechanism 4 have better stability, thereby reducing the occurrence of the above situation.

[0058] In some embodiments of the present application, as shown in Figure 3 The support mechanism 4 has a second through hole 402, the second through hole 402 is in communication with the first through hole 401, and the adjusting mechanism 5 includes a bolt 51, the bolt 51 is threadedly connected with the second through hole 402.

[0059] It can be understood that the second through hole 402 provides a channel for the adjusting mechanism 5 to extend into the first through hole 401. The bolt 51 is threadedly connected with the second through hole 402, and the length of the bolt 51 extending into the second through hole 402 can be adjusted by adjusting the threaded position of the bolt 51 and the second through hole 402. By adjusting the length of the bolt 51 extending into the second through hole 402, the pressure generated by the bolt 51 on the clamping mechanism 3 can be adjusted, thereby adjusting the frictional force acting on the clamping mechanism 3 during movement.

[0060] In some embodiments of the present application, as shown in Figure 2 The support mechanism 4 includes a support 41, a first connecting rod 42 and a second connecting rod 43, the first connecting rod 42 is hinged with the second connecting rod 43, the second connecting rod 43 is hinged with the support 41, the first connecting rod 42 is connected with the clamping mechanism 3, an axis of rotation of the first connecting rod 42 is perpendicular to the first axis, and an axis of rotation of the second connecting rod 43 is parallel to the first axis.

[0061] It can be understood that the support 41 supports the second connecting rod 43, so that the second connecting rod 43 can rotate, and cooperates with the first connecting rod 42 to adjust the relative position between the adjusting mechanism 5 and the object table 1, which is conducive to the clamping mechanism 3 clamping various materials with different volumes and shapes.

[0062] In some embodiments of the application, as shown in Figure 2 The support mechanism 4 comprises a level 44, which is installed on the first connecting rod 42.

[0063] It can be understood that the level 44 can provide a reference standard for the staff when adjusting the position of the material. When the level 44 is in a horizontal state, it can indicate that the first connecting rod 42 is in a horizontal state, which is conducive to the movement of the clamping mechanism 3 along the first axis and the material adhering to the stage 1 under the action of the weight.

[0064] In some embodiments of the application, as shown in Figure 1 The grinding device comprises a cleaning mechanism 6 for supplying water to the side of the stage 1 facing the clamping part 31, and the stage 1 has a drain hole 101, one end of which extends to the side of the stage 1 facing the clamping part 31.

[0065] It can be understood that the cleaning mechanism 6 can clean the debris generated by grinding the material to another place through the drain hole 101, so that it does not remain on the surface of the stage 1 and rub against the material and the stage 1, which is conducive to improving the grinding effect.

[0066] In some embodiments of the application, as shown in Figure 1 The cleaning mechanism 6 comprises a treatment barrel 61, which is in communication with the other end of the drain hole 101.

[0067] It can be understood that the treatment barrel 61 can collect sewage and debris from the drain hole 101, which is conducive to the unified collection and cleaning of the garbage generated by grinding.

[0068] In some embodiments of the application, as shown in Figure 1 The side of the stage 1 facing the clamping part 31 is perpendicular to the first axis.

[0069] It can be understood that such an arrangement is conducive to the clamping mechanism 3 pressing the material on the stage 1 by the action of its gravity, and adhering to the stage 1, so that the stage 1 can realize grinding of the material by rotating.

[0070] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be construed or implied to indicate or imply relative importance. The term "a plurality of" means two or more, unless otherwise explicitly limited.
