For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific circumstances.

[0078] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0079] Please refer to Figure 1 , an abrasive device 100 for grinding a workpiece 200 is provided in an embodiment of the present application, which includes a rotating assembly 10, a sliding assembly 20 slidably provided on one side of the rotating assembly 10, an adjusting assembly 30 slidably connected to the sliding assembly 20, and an abrasive assembly 40 connected to the adjusting assembly 30. Among them, the workpiece 200 can be a guide post, a guide sleeve, etc. In this embodiment, the workpiece 200 is a guide post.

[0080] For the convenience of understanding and explanation, a three-dimensional coordinate system is established in some of the accompanying drawings. The first direction is Figure 1 the X-axis direction shown in Figure 1 the Y-axis direction shown in Figure 1The shown Z-axis direction, X-axis direction, Y-axis direction, and Z-axis direction are perpendicular to each other in pairs.

[0081] Please refer to Figure 1 , the rotating assembly 10 includes a base 11 fixedly provided on one side of the sliding assembly 20, a clamping member 12 rotatably connected to the base 11, and a rotating handle 13 connected to the clamping member 12. The base 11 is generally block-shaped, the base 11 is fixedly provided on one side of the sliding assembly 20, the clamping member 12 movably passes through the base 11 and is rotatably connected to the base 11, the clamping member 12 clamps the workpiece 200, the rotating handle 13 is generally rod-shaped, the rotating handle 13 is connected to the clamping member 12, and the rotating handle 13 drives the clamping member 12 and the workpiece 200 to rotate in a preset direction. Exemplarily, the clamping member 12 can be any clamping body, clamping block or similar clamping part that can clamp the workpiece 200.

[0082] Thus, by driving the clamping member 12 and the workpiece 200 clamped by the clamping member 12 to rotate synchronously in a preset direction through the rotating handle 13, the grinding assembly 40 grinds different parts of the workpiece 200, and at the same time, friction is generated between the workpiece 200 and the grinding assembly 40 during the rotation process of the workpiece 200, so that the grinding assembly 40 stably grinds the workpiece 200.

[0083] Among them, in this embodiment, the above preset direction is the clockwise direction. In other embodiments, the preset direction can also be the counterclockwise direction.

[0084] Please refer to Figure 2 , the sliding assembly 20 includes two limiting members 21 spaced apart on one side of the base 11, two guiding members 22 respectively connected to the two limiting members 21, a sliding member 23 slidably connected to the two guiding members 22 respectively, and a sliding handle 24 connected to the sliding member 23. Both of the two limiting members 21 are generally block-shaped, the two limiting members 21 are provided on the same side of the rotating assembly 10 and are spaced apart along the first direction. Both of the two guiding members 22 are generally rod-shaped, the two guiding members 22 are spaced apart along the second direction, and both ends of each guiding member 22 are respectively connected to the two limiting members 21. The sliding member 23 is generally block-shaped, the sliding member 23 is sleeved on the two guiding members 22 and is slidably connected to the two guiding members 22 respectively along the first direction, the sliding member 23 is slidably connected to the adjusting assembly 30 along the second direction, and the sliding member 23 slides between the two limiting members 21 along the first direction under the guidance of the guiding members 22. The sliding handle 24 is generally L-shaped, the sliding handle 24 is connected to the sliding member 23, and the sliding handle 24 drives the sliding member 23 to slide along the first direction.

[0085] In this way, the sliding member 23 slides stably along the first direction under the guidance of the guiding member 22, so that the sliding member 23 drives the adjusting component 30 and the grinding component 40 to slide relative to the workpiece 200 along the first direction, thereby enabling the grinding component 40 to accurately correspond to the area to be ground of the workpiece 200 in the first direction, and further enabling the grinding component 40 to grind the workpiece 200 stably. In addition, by arranging the two limiting members 21 on both sides of the sliding member 23 along the first direction, when the sliding member 23 slides to a preset position along the first direction, it abuts against the corresponding limiting member 21, so that the limiting member 21 limits the moving distance of the sliding member 23, preventing the moving distance of the sliding member 23 from being too large and separating from the guiding member 22, which is beneficial to ensuring the stable sliding of the sliding member 23. In addition, by setting the sliding handle 24 to be connected to the sliding member 23, it is convenient for the operator to act on the sliding handle 24, so that the sliding handle 24 drives the sliding member 23 to slide along the first direction under the action of an external force, and avoids using complex electric driving devices, pneumatic driving devices, etc. to drive the sliding member 23 to slide, simplifying the mechanical structure of the sliding component 20 and reducing the use cost.

[0086] Please continue to refer to Figure 2 The sliding member 23 includes a sliding body 231 connected to the guiding member 22 and a fixing body 232 connected to the sliding body 231. The sliding body 231 is generally block-shaped, the sliding body 231 is sleeved on the guiding member 22 and is provided with a sliding groove 2311. The sliding groove 2311 is opened on the side of the sliding body 231 facing away from the guiding member 22. The sliding groove 2311 houses a part of the adjusting component 30 and is slidably connected to the adjusting component 30 to guide the sliding direction of the adjusting component 30. The fixing body 232 is generally block-shaped, and the fixing body 232 is connected to the sliding body 231.

[0087] In this way, by housing a part of the adjusting component 30 in the sliding groove 2311, the sliding body 231 is slidably connected to the adjusting component 30 through the sliding groove 2311, so that the sliding groove 2311 limits the sliding direction of the adjusting component 30, which is beneficial to the stable adjustment of the position of the grinding component 40 by the adjusting component 30.

[0088] Please refer to Figure 1 and Figure 2 The adjusting component 30 includes a support member 31 slidably connected to the sliding body 231 and an adjusting member 32 threadedly connected to the support member 31. The support member 31 is generally block-shaped, the support member 31 is slidably connected to the sliding body 231 along the second direction. The adjusting member 32 is generally rod-shaped, the adjusting member 32 is movably inserted through the support member 31 along the second direction and is threadedly connected to the support member 31. The adjusting member 32 is rotatably connected to the fixing body 232, and the adjusting member 32 drives the support member 31 to slide along the second direction. The protective member 33 is generally plate-shaped, the protective member 33 covers the sliding groove 2311 and is connected to the support member 31, and the protective member 33 protects the sliding groove 2311.

[0089] Thus, by providing a rotational connection between the adjusting member 32 and the fixed body 232, and by providing a threaded connection between the adjusting member 32 and the support member 31, the adjusting member 32, the support member 31, and the fixed body 232 form a screw linkage mechanism, so that when the adjusting member 32 rotates in a predetermined direction, the support member 31 is driven to slide in a second direction relative to the sliding body 231, thereby adjusting the position of the grinding assembly 40 connected to the support member 31, thereby allowing the grinding assembly 40 to stably grind the workpiece 200. In addition, the guard member 33 is provided in the sliding groove 2311, thereby protecting the sliding groove 2311 and preventing external debris, oil, etc. from entering the sliding groove 2311 and interfering with the normal sliding of the support member 31.

[0090] See also Figure 2 The adjusting member 32 includes an adjusting body 321 rotatably connected to the fixed body 232, two limiting bodies 322 spaced apart and respectively connected to the adjusting body 321, and a rotating handle 323 connected to the adjusting body 321. The adjusting body 321 is generally rod-shaped, movably passed through the fixed body 232 and rotatably connected to the fixed body 232, and the adjusting body 321 is threadedly connected to the support member 31. The two limiting bodies 322 are both generally cylindrical, spaced apart along the second direction from the adjusting body 321 and respectively connected to the adjusting body 321, and the fixed body 232 is located between the two limiting bodies 322. The rotating handle 323 is generally rod-shaped, connected to the end of the adjusting body 321 away from the support member 31, and the rotating handle 323 drives the adjusting body 321 to rotate.

[0091] Thus, by positioning the fixed body 232 between the two limiting bodies 322, the two limiting bodies 322 limit the position of the adjusting body 321, preventing the adjusting body 321 from shifting in the second direction during rotation. This allows the adjusting body 321 to rotate at a fixed position, thereby ensuring that the adjusting body 321 stably drives the support member 31 to slide in the second direction. Furthermore, by connecting the rotating handle 323 to the adjusting body 321, an operator can easily apply force to the rotating handle 323, causing the rotating handle 323 to drive the adjusting body 321 to rotate under the action of an external force. This avoids the need for complex electric or pneumatic drive devices to drive the adjusting body 321, thereby simplifying the mechanical structure of the adjusting assembly 30 and reducing its operating costs.

[0092] See also Figure 1 and Figure 3The grinding assembly 40 includes a linkage member 41 connected to the support member 31, a connecting member 42 movably connected to the linkage member 41, four elastic members 43 respectively abutting the linkage member 41, a grinding member 44 detachably connected to the connecting member 42, and two limiting members 45 arranged at intervals and respectively connected to the connecting member 42. The linkage member 41 is generally block-shaped and connected to the side of the support member 31 facing away from the sliding member 23. The connecting member 42 is movably connected to the linkage member 41. The four elastic members 43 are evenly spaced, and the elastic force direction of each elastic member 43 is parallel to the second direction. The two ends of each elastic member 43 elastically abut the linkage member 41 and the connecting member 42 respectively. The grinding member 44 is generally sheet-shaped and is arranged on the side of the connecting member 42 facing away from the linkage member 41 and is detachably connected to the connecting member 42. The grinding member 44 grinds the workpiece 200 rotating along a preset direction. The two limiting members 45 are both substantially rod-shaped and are arranged parallel to each other along the first direction. Each limiting member 45 is movably provided on the linkage member 41 and connected to the connecting member 42. For example, the elastic member 43 can be a spring and the polishing member 44 can be polishing cotton.

[0093] In this way, by providing the two ends of the elastic member 43 to elastically abut against the linkage member 41 and the connecting member 42 respectively, when the linkage member 41 drives the connecting member 42 and the connected grinding member 44 to abut against the workpiece 200, the linkage member 41 compresses the elastic member 43 toward the connecting member 42, so that a flexible contact is formed between the grinding member 44 connected to the connecting member 42 and the workpiece 200, thereby preventing the grinding member 44 from applying excessive force to the workpiece 200 and damaging the workpiece 200, thereby improving the grinding accuracy and the quality of the workpiece 200. In addition, by providing a limiting member 45 movably passing through the linkage member 41, the limiting member 45 limits the movement direction of the linkage member 41, so that the linkage member 41 always slides in the second direction and compresses the elastic member 43, thereby ensuring that the grinding member 44 can achieve flexible grinding of the workpiece 200.

[0094] See also Figure 3 The linkage member 41 includes a linkage body 411 connected to the support member 31 and four abutting bodies 412 connected to the connecting member 42 and spaced apart. The linkage body 411 is roughly block-shaped, connected to the support member 31, and abuts against the elastic member 43. The four abutting bodies 412 are all roughly rod-shaped, evenly spaced apart and corresponding to the four elastic members 43 one by one, one end of each abutting body 412 is movably passed through the corresponding elastic member 43 and connected to the connecting member 42, and the other end of each abutting body 412 abuts against the side of the linkage body 411 away from the connecting member 42, so that the linkage body 411 is movably connected to the connecting member 42. Exemplarily, the abutting body 412 can be a bolt.

[0095] In this way, by providing the abutting body 412 to be movably inserted into the corresponding elastic member 43 and connected to the connecting member 42, a movable connection is formed between the connecting member 42 and the linkage member 41, so that the linkage member 411 compresses the elastic member 43 toward the connecting member 42, thereby ensuring flexible contact between the polishing member 44 connected to the connecting member 42 and the workpiece 200. In addition, after the workpiece 200 is polished, the polishing member 44 and the polished workpiece 200 are loosened from each other, and the compressed elastic member 43 provides elastic force to drive the linkage member 411 to move away from the connecting member 42, so that the other end of the abutting body 412 away from the connecting member 42 abuts against the side of the linkage member 411 facing away from the connecting member 42, thereby limiting the movement distance of the linkage member 411 and preventing the linkage member 411 from separating from the abutting body 412.

[0096] Please continue reading Figure 3 The connecting member 42 includes a connecting body 421 connected to the abutting body 412 and a plurality of locking bodies 422 detachably connected to the connecting body 421 and spaced apart. The connecting body 421 is connected to the abutting body 412 and the limiting member 45 respectively, and the connecting body 421 abuts against the elastic member 43. The plurality of locking bodies 422 are divided into two groups, and the two groups of locking bodies 422 are spaced apart along the third direction. The number of locking bodies 422 in each group is six, and the locking bodies 422 in the same group are spaced apart along the first direction. Each locking body 422 is passed through the polishing member 44 and is threadedly connected to the connecting body 421. For example, the locking body 422 can be a screw. In other embodiments, the number of the locking bodies 422 can also be two, three, four, etc.

[0097] In this way, the locking body 422 is passed through the grinding piece 44 and is threadedly connected to the connecting body 421, so that the grinding piece 44 and the connecting body 421 can be detachably connected, which is convenient for replacing the easily worn grinding piece 44, so that the grinding assembly 40 can continuously and stably grind the workpiece 200.

[0098] The working process of the above-mentioned grinding device 100 is roughly as follows:

[0099] First, the clamping member 12 clamps and fixes the workpiece 200 to be polished. The operator acts on the sliding handle 24 to drive the sliding member 23 to slide along the first direction under the guidance of the guide member 22, so that the polishing member 44 corresponds to the position to be polished on the workpiece 200.

[0100] Then, the operator rotates the handle 323 to drive the adjusting body 321 to drive the support member 31 to move in the second direction toward the workpiece 200. Driven by the support member 31, the linkage member 41 compresses the elastic member 43 to the connecting member 42, so that the grinding member 44 is in flexible contact with the workpiece 200 to be ground.

[0101] Finally, the operator acts on the rotating handle 13 to drive the clamping member 12 to drive the workpiece 200 to rotate synchronously along the preset direction, so that the grinding member 44 grinds the workpiece 200 rotating along the preset direction.

[0102] The above-mentioned grinding device 100 drives the grinding part 44 to slide along the first direction through the sliding part 23, so that the grinding part 44 corresponds to the position to be ground of the workpiece 200, and drives the support part 31 to move close to the workpiece 200 to be ground through the adjusting part 32, so that the linkage part 41 compresses the elastic part 43 to the connecting part 42, so that a flexible contact is formed between the grinding part 44 and the workpiece 200 to be ground, and then the grinding part 44 grinds the workpiece 200 rotating along the preset direction, without the need for manual grinding operations, thereby improving the grinding efficiency.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
