For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0081] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0082] See also Figure 1 and Figure 2 The embodiment of the present application provides a grinding device 100, which includes a clamping mechanism 10, a grinding mechanism 20, a feeding mechanism 30 and a rotating mechanism 40. The grinding device 100 is used to grind a workpiece 200. It can be understood that in this embodiment, the workpiece 200 is a main axis.

[0083] See also Figure 1 The clamping mechanism 10 is used to load a workpiece 200 having a hole 201. The grinding mechanism 20 is arranged on one side of the clamping mechanism 10. The grinding mechanism 20 includes a grinding piece 21. The grinding piece 21 is used to extend into the hole 201 on the workpiece 200 and rotate along a preset direction to grind the inner wall of the hole 201 on the workpiece 200. The feeding mechanism 30 is connected to the grinding mechanism 20 and is used to drive the grinding mechanism 20 to approach or move away from the workpiece 200 to adjust the grinding piece 21 to enter and exit the hole 201 on the workpiece 200. The rotating mechanism 40 is arranged on the other side of the clamping mechanism 10. The rotating mechanism 40 is used to connect the workpiece 200 and drive the workpiece 200 to rotate in a direction opposite to the preset direction to cooperate with the grinding mechanism 20 to grind the inner wall of the hole 201 of the workpiece 200. Among them, the preset reverse direction is taken as an example to explain, and the direction opposite to the preset direction is the counterclockwise direction.

[0084] The above-mentioned grinding device 100 rotates along a preset direction by the grinding piece 21 extending into the hole 201 on the workpiece 200, and drives the workpiece 200 loaded by the clamping mechanism 10 to rotate in a direction opposite to the preset direction through the rotating mechanism 40, so that the rotating mechanism 40 and the grinding piece 21 cooperate to grind the inner wall of the hole 201 on the workpiece 200, thereby quickly completing the grinding operation and improving the grinding efficiency. The feeding mechanism 30 drives the grinding piece 21 to approach or move away from the workpiece 200 to adjust the grinding piece 21 to enter and exit the hole 201 on the workpiece 200, thereby controlling the depth of the hole 201 on the workpiece 200 polished by the grinding piece 21, so as to reduce the grinding difficulty, thereby ensuring the grinding depth requirement of the hole wall and improving the grinding accuracy.

[0085] See also Figure 1 In some embodiments, the grinding mechanism 20 further includes a support member 22, a grinding drive member 23 and an adjusting member 24. The support member 22 is connected to the feeding mechanism 30, and the grinding drive member 23 is slidably disposed on the support member 22 in a direction perpendicular to the direction in which the grinding member 21 enters and exits the hole 201 on the workpiece 200, and is connected to the grinding member 21, and the grinding drive member 23 is used to drive the grinding member 21 to rotate in a preset direction. The adjusting member 24 is disposed on the support member 22, and is used to drive the grinding drive member 23 to drive the grinding member 21 to move in a direction perpendicular to the direction in which the grinding member 21 enters and exits the hole 201 on the workpiece 200, so as to adjust the depth of the hole 201 on the workpiece 200 that the grinding member 21 grinds. Exemplarily, the grinding drive member 23 can be a rotary cylinder, a rotary motor, etc.

[0086] In this way, by adjusting the adjustment part 24 in the direction perpendicular to the direction in which the grinding part 21 enters and exits the hole 201 on the workpiece 200, the radial grinding depth of the grinding part 21 in the hole 201 is adjusted, so that the grinding part 21 can stably grind the hole wall of the hole 201 on the workpiece 200, avoiding the hole wall not being polished properly due to too small grinding depth, or the hole wall of the workpiece 200 being too thin and reducing the structural strength of the workpiece 200 due to too large grinding depth, thereby achieving precise grinding of the inner wall of the hole 201 of the workpiece 200 and improving the grinding accuracy.

[0087] Please continue reading Figure 1 In some embodiments, the feeding mechanism 30 includes a base plate 31, a slide rail 32 and a feeding driver 33. The base plate 31 is movably disposed on one side of the clamping mechanism 10. The slide rail 32 is extended along the direction in which the grinding piece 21 enters and exits the hole 201 on the workpiece 200 and is connected to the base plate 31, and the support member 22 is slidably disposed on the slide rail 32. The feeding driver 33 is spaced apart from the slide rail 32 on the base plate 31 and is connected to the support member 22, and the feeding driver 33 is used to drive the grinding piece 21 to move closer to or away from the workpiece 200. Exemplarily, the feeding driver 33 can be a linear cylinder.

[0088] The holes 201 of one part of the workpiece 200 are straight holes, and the holes 201 of another part are tapered holes. In this way, by movably arranging the substrate 31 on one side of the clamping mechanism 10, it is convenient for the operator to adjust the inclination direction of the substrate 31. For example, the angle between the inclination direction of the substrate 31 and the direction of the rotating mechanism 40 pointing to the clamping mechanism 10 is 30°, so that the grinding piece 21 can adapt to the hole 201 structure of different workpieces 200, and then the grinding piece 21 can stably grind the holes 201 on the workpiece 200, thereby improving the grinding stability.

[0089] See also Figure 1 and Figure 3In some embodiments, the support member 22 includes a support body 221 and an elastic body 222. The support body 221 is connected to the feeding mechanism 30, the grinding drive member 23 is slidably disposed on the support body 221, and the adjustment member 24 is spaced apart from the grinding drive member 23 and disposed on the support body 221. The elastic body 222 is connected to the support body 221 and elastically abuts against the grinding drive member 23.

[0090] In this way, by setting the elastic body 222 and the polishing drive member 23 to elastically support each other, when the adjusting member 24 adjusts the polishing position of the polishing drive member 23, the polishing drive member 23 compresses the elastic body 222. When the polishing device 100 completes the polishing operation, the adjusting body 242 separates from the polishing drive member 23, and the compressed elastic body 222 provides elastic force to drive the polishing drive member 23 to return to the initial position, so as to facilitate repeated adjustment of the polishing position of the polishing drive member 23, so that the polishing device 100 can be adapted to holes 201 of different types of workpieces 200.

[0091] See also Figure 3 In some embodiments, the elastic body 222 includes a fixing portion 2221, a limiting portion 2222, a contact portion 2223 and an elastic portion 2224. The fixing portion 2221 and the adjusting member 24 are arranged on both sides of the grinding drive member 23 in a direction perpendicular to the direction in which the grinding member 21 enters and exits the hole 201 on the workpiece 200, and the fixing portion 2221 is connected to the supporting body 221. One end of the limiting portion 2222 is movably arranged in the fixing portion 2221, and the limiting portion 2222 is used to contact the side of the fixing portion 2221 away from the adjusting member 24. The contact portion 2223 is connected to the limiting portion 2222 adjacent to the adjusting member 24 and contacts the grinding drive member 23. The elastic force direction of the elastic part 2224 is parallel to the direction of the fixing part 2221 pointing to the adjusting member 24. The elastic part 2224 is sleeved on the limiting part 2222. The two ends of the elastic part 2224 elastically abut against the fixing part 2221 and the abutting part 2223. Exemplarily, the elastic part 2224 can be a spring.

[0092] In this way, by setting the specific structure of the elastic body 222, when the grinding position of the grinding drive 23 is adjusted, the grinding drive 23 pushes the abutment part 2223 to move close to the fixed part 2221 and compresses the elastic part 2224 to the fixed part 2221. After the grinding operation of the workpiece 200 is completed, the elastic part 2224 provides elastic force and drives the abutment part 2223 to push the grinding drive 23 to reset. The limiting part 2222 abuts against the side of the fixed part 2221 away from the elastic part 2224, thereby limiting the abutment part 2223 to prevent the abutment part 2223 from moving too far and separating from the fixed part 2221 and the elastic part 2224, which is beneficial to ensure the repeated operation of the elastic body 222.

[0093] See also Figure 1In some embodiments, the adjusting member 24 includes a connecting body 241 and an adjusting body 242. The connecting body 241 is disposed on the supporting body 221, the adjusting body 242 is movably disposed through the connecting body 241 and is threadedly connected to the connecting body 241, and the adjusting body 242 and the elastic body 222 are respectively abutted against two sides of the grinding driving member 23, and the adjusting body 242 is used to push the grinding driving member 23 to move close to the elastic body 222 and compress the elastic body 222 under the action of external force, so as to adjust the grinding driving member 23 to a preset position.

[0094] In this way, by setting a threaded connection between the adjusting body 242 and the connecting body 241, the operator can adjust the length of the adjusting body 242 extending from the connecting body 241 according to the grinding requirements of different workpieces 200, and then adjust the grinding drive 23 to a preset position, so that the grinding member 21 connected to the grinding drive 23 grinds the hole wall of the workpiece 200 to a preset grinding depth, thereby improving the grinding stability. In addition, the mechanical structure of the adjusting member 24 is simple, which reduces the cost of use.

[0095] In other embodiments, the adjusting member 24 may also be a linear cylinder, which directly pushes the grinding driving member 23 to move close to the fixing portion 2221 to adjust the grinding position of the grinding driving member 23 .

[0096] Please continue reading Figure 1 In some embodiments, the clamping mechanism 10 includes a carrier 11 and a clamping member 12. The carrier 11 is disposed between the rotating mechanism 40 and the feeding mechanism 30, and is used to carry the workpiece 200. The clamping member 12 is connected to the carrier 11, and is used to fix the workpiece 200. Figure 2 Specifically, the workpiece 200 includes a shaft core 202 and a sleeve 203 . The shaft core 202 is movably inserted into the sleeve 203 and is rotatably connected to the sleeve 203 . One end of the shaft core 202 is provided with the above-mentioned hole 201 structure, and the other end of the shaft core 202 is connected to the rotating mechanism 40 .

[0097] In this way, by supporting the sleeve 203 of the workpiece 200 through the supporting member 11 and clamping and fixing the sleeve 203 through the clamping member 12, the sleeve 203 can be fixed on the supporting member 11 to prevent the sleeve 203 from synchronously rotating when the rotating mechanism 40 drives the shaft core 202 to rotate and causing the workpiece 200 to shift on the supporting member 11, so that the sleeve 203 can stably maintain the placement position and orientation during the grinding process, and then the grinding member 21 can stably grind the hole 201 of the shaft core 202 in the fixed sleeve 203.

[0098] See also Figure 1 and Figure 2In some embodiments, the carrier 11 is provided with a receiving groove 111 adapted to the workpiece 200, the clamping member 12 is an arc-shaped clamping body 121, one end of the clamping member 12 is rotatably connected to the carrier 11, and the other end of the clamping member 12 is detachably connected to the carrier 11, and the clamping member 12 is used to cooperate with the receiving groove 111 to clamp and fix the workpiece 200.

[0099] In this way, by setting the clamping member 12 as an arc-shaped clamping body 121, the clamping member 12 can utilize the arc-shaped structure of the arc-shaped clamping body 121 and the storage groove 111 to cooperate to form a circular groove that is compatible with the outer periphery of the sleeve 203, so that the clamping member 12 and the groove wall of the storage groove 111 are stably fitted to the peripheral side of the sleeve 203, thereby enabling the clamping member 12 to stably clamp and fix the sleeve 203.

[0100] See also Figure 1 In some embodiments, the rotating mechanism 40 includes a sliding member 41, a rotating member 42 and a distance changing member 43. The sliding member 41 is slidably disposed on the side of the clamping mechanism 10 away from the feeding mechanism 30, and the rotating member 42 is disposed on the sliding member 41. The rotating member 42 is used to drive the workpiece 200 to rotate in a direction opposite to the preset direction. The distance changing member 43 is disposed at one end of the sliding member 41 away from the clamping mechanism 10 and connected to the sliding member 41. The distance changing member 43 is used to drive the sliding member 41 to move closer to or away from the clamping mechanism 10 to adjust the distance between the rotating member 42 and the workpiece 200. Exemplarily, the rotating member 42 can be a rotary cylinder, a rotary motor, etc., and the distance changing member 43 can be any distance changing part, distance changing body or similar distance changing block capable of adjusting the distance between the rotating member 42 and the workpiece 200, such as an adjusting hand wheel, a linear cylinder, etc.

[0101] In this way, by setting the specific structure of the above-mentioned rotating mechanism 40, the distance variable member 43 can drive the sliding member 41 to move closer to or away from the clamping mechanism 10, so as to adjust the distance between the rotating member 42 and the workpiece 200, so that the output end of the rotating member 42 is stably connected to the end of the shaft core 202 away from the hole 201, and then the rotating member 42 can stably drive the shaft core 202 to rotate in a direction opposite to the preset direction.

[0102] See also Figure 1 and Figure 3 In some embodiments, the grinding device 100 further includes a trimming mechanism 50, and the trimming mechanism 50 includes a fixing member 51 and a trimming member 52. The fixing member 51 is disposed on one side of the clamping mechanism 10, and the trimming member 52 is slidably disposed on the fixing member 51 and detachably connected to the fixing member 51, and the trimming member 52 is used to trim the grinding member 21. It can be understood that the trimming member 52 and the fixing member 51 can be pluggably connected or threadedly connected, and the trimming member 52 can be fixed to the fixing member 51 after the operator adjusts the trimming position of the trimming member 52.

[0103] In this way, by setting the trimming piece 52 and the fixing piece 51 to be detachably connected, the operator can adjust the trimming piece 52 to a position close to the clamping mechanism 10 during the trimming operation, so that the trimming piece 52 abuts against the outer periphery of the grinding piece 21, so as to stably trim the grinding piece 21, avoid the grinding piece 21 from being damaged and being unable to accurately grind the workpiece 200, thereby ensuring the grinding accuracy of the grinding piece 21. After the trimming is completed, the operator adjusts the trimming piece 52 to a position away from the clamping mechanism 10, so that a sufficiently large avoidance distance is formed between the trimming piece 52 and the workpiece 200 fixed by the clamping mechanism 10, to prevent the grinding piece 21 from interfering with the trimming piece 52 when grinding the hole 201 of the workpiece 200.

[0104] The working process of the above-mentioned grinding device 100 is roughly as follows:

[0105] First, the sleeve 203 with the shaft core 202 is placed in the receiving groove 111, and the clamping member 12 uses the arc structure of the arc clamping body 121 to cooperate with the receiving groove 111 to clamp and fix the sleeve 203, and the distance changing member 43 adjusts the distance between the rotating member 42 and the shaft core 202, so that the rotating member 42 is connected to the end of the shaft core 202 away from the hole 201;

[0106] Secondly, the operator adjusts the length of the adjusting body 242 extending out of the connecting body 241 according to the grinding requirements of the workpiece 200, and then the adjusting body 242 moves in the direction perpendicular to the direction in which the grinding piece 21 enters and exits the hole 201 on the workpiece 200, so as to adjust the grinding depth of the grinding piece 21 in the radial direction of the hole 201;

[0107] Finally, the feed drive 33 drives the grinding piece 21 to extend into the hole 201 on the shaft core 202, and the grinding drive 23 drives the grinding piece 21 to rotate in a preset direction, and drives the shaft core 202 to rotate in a direction opposite to the preset direction through the rotating piece 42, so that the rotating piece 42 and the grinding piece 21 cooperate to grind the inner wall of the hole 201 on the shaft core 202, so as to quickly complete the grinding operation and improve the grinding efficiency. At the same time, the feed drive 33 drives the grinding piece 21 to move closer to or away from the shaft core 202 during the grinding process to adjust the depth of the grinding piece 21 entering and exiting the hole 201 on the workpiece 200, thereby controlling the depth of the hole 201 on the workpiece 200 polished by the grinding piece 21, so as to reduce the grinding difficulty, thereby ensuring the grinding depth requirement of the hole wall and improving the grinding accuracy.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
