Description
Technical Field
[0001] This application relates to the field of surface treatment technology, specifically to a polishing device. Background Technology
[0002] In the manufacturing process, surface treatments such as grinding and polishing are often required for workpieces. Currently, commonly used grinding equipment is generally only suitable for grinding plate-shaped workpieces or flat structures. However, for rod-shaped workpieces, due to their rounded sides and spherical or curved ends, traditional grinding equipment struggles to ensure uniform grinding. If rod-shaped workpieces are mounted on a rotating device for grinding, workpiece bending is likely to occur during the grinding process, leading to a reduced grinding yield. Utility Model Content
[0003] In view of the above, it is necessary to propose a grinding equipment that can grind workpieces, ensure grinding uniformity, and improve grinding yield.
[0004] This application provides a grinding device, including: a rotating mechanism, comprising a rotating drive and a connecting assembly, the connecting assembly being connected to the rotating drive and used to connect a workpiece, the rotating drive driving the workpiece to rotate around its axis via the connecting assembly; a bearing mechanism, comprising two parallel bearing rollers, the two bearing rollers extending along a first direction and spaced apart along a second direction perpendicular to the first direction, the two bearing rollers being configured to jointly support the workpiece; and a pressing mechanism, comprising a pressing drive and a pressing element, the pressing drive being spaced apart from the bearing rollers along the second direction, the pressing element being connected to... The following components are connected to the pressing drive, which drives the pressing member to move closer to or away from the support roller to press or release the workpiece; a pushing mechanism, including a pushing drive and a pushing member, wherein the pushing drive is spaced apart from the support roller along the first direction, and the pushing member is connected to the pushing drive, which drives the pushing member to move closer to or away from the support roller to push the pushing member against the workpiece on the support roller to the connecting assembly, or to move the pushing member away from the workpiece; and a grinding mechanism, adjacent to the support mechanism, wherein the grinding mechanism includes a grinding member for grinding the workpiece.
[0005] The aforementioned grinding equipment uses two support rollers in the support mechanism to support the workpiece to be ground. A pusher in the pusher mechanism drives a pusher to push the workpiece towards the connecting assembly in the rotating mechanism, thus connecting the workpiece to the connecting assembly. When grinding the end of the workpiece, the pusher drives the pusher away from the workpiece to avoid it, and the pressure mechanism drives the pressure member to press the workpiece on the support rollers. The grinding member in the grinding mechanism abuts against the end of the workpiece, and the rotating drive, through the connecting assembly, rotates the workpiece, thereby grinding the end of the workpiece. When grinding the sidewall of the workpiece, the pressure mechanism drives the pressure member away from the workpiece to avoid it, and the grinding member abuts against the sidewall of the workpiece. The rotating drive, through the connecting assembly, rotates the workpiece, thereby grinding the sidewall of the workpiece.
[0006] The aforementioned grinding equipment utilizes a carrying mechanism to support the workpiece, a rotating mechanism to drive the workpiece to rotate, a pushing mechanism to improve the consistency of workpiece installation position, and a pressing mechanism to hold the workpiece in place when grinding the end, preventing bending deformation and improving grinding yield. When grinding the sidewalls of the workpiece, two carrying rollers support it, preventing bending deformation and further improving grinding yield. The rotating drive component, through connecting components, keeps the workpiece rotating throughout the grinding process, effectively improving grinding uniformity.

The elastic collet has a clamping hole extending along the first direction. The collet cap is movably sleeved on the end of the rotating shaft away from the rotary drive and abuts against the elastic collet. The clamping hole is used to receive one end of the workpiece. The collet cap moves toward the rotary drive to push the elastic collet to clamp the workpiece. The first elastic element is used to push the elastic collet to move along the first direction when the collet cap moves away from the rotary drive, so that the elastic collet releases the workpiece.
[0008] In some embodiments, the receiving groove is provided with an inclined inner wall, the inclined inner wall is connected to the opening of the receiving groove, and the inclined inner wall gradually moves away from the axis of the rotating shaft along the first direction, and the elastic collet abuts against the inclined inner wall.

The second elastic member is disposed in the receiving cavity and sleeved on the rotating shaft. The two ends of the second elastic member abut against the inner wall of the receiving cavity and the baffle, respectively. The elasticity of the second elastic member is greater than the elastic force of the first elastic member. The second elastic member is used to push the movable sleeve toward the rotary drive member.
[0010] In some embodiments, the rotating mechanism further includes a loosening assembly, which includes a loosening drive and a traction member. The loosening drive is disposed near the rotating shaft, and the traction member is connected to the loosening drive. An annular groove is formed on the outer wall of the movable sleeve, and one end of the traction member away from the loosening drive is mounted in the annular groove. The loosening drive drives the traction member to move along the first direction, so that the traction member pushes the movable sleeve away from the rotating drive in the first direction.
[0011] In some embodiments, the workpiece includes a connecting portion and a portion to be polished connected together, the connecting portion having a blind groove; the connecting assembly further includes a positioning pin, the positioning pin being disposed in the receiving groove and coaxially disposed with the rotating shaft, the positioning pin being used to insert into the blind groove of the workpiece to position the workpiece.

[0024] The embodiments of this application will be further described below with reference to the accompanying drawings. To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system is established in some of the drawings, with the X-axis direction as the first direction, the Y-axis direction as the second direction, and the Z-axis direction as the third direction. The X-axis direction, Y-axis direction, and Z-axis direction are perpendicular to each other.
[0025] Please see Figure 1 and Figure 2 This application provides a grinding device 100 for grinding the outer surface of a workpiece 200. The workpiece 200 can be a cylindrical rod-shaped structure. In this embodiment, the workpiece 200 includes a connected connecting portion 201 and a portion to be ground 202. The connecting portion 201 does not need to be ground. The portion to be ground 202 includes one end of the workpiece 200 and a peripheral sidewall adjacent to that end. In other embodiments, the peripheral sidewall and both ends of the workpiece 200 can be ground. When grinding both ends of the workpiece 200, after grinding one end, the workpiece 200 needs to be disassembled and reinstalled to expose the other end to be ground. The grinding device 100 includes a rotating mechanism 10, a bearing mechanism 20, a pressing mechanism 30, a pushing mechanism 40, and a grinding mechanism 50.
[0026] Specifically, the rotating mechanism 10 includes a rotating drive component 11 and a connecting assembly 12. The connecting assembly 12 is connected to the rotating drive component 11 and is used to connect the workpiece 200. The rotating drive component 11 drives the workpiece 200 to rotate around its axis via the connecting assembly 12. The rotating drive component 11 can be a rotary motor, a rotary cylinder, etc., and the connecting assembly 12 can be connected to one end of the workpiece 200, such as through a clamping connection. It can be understood that after the workpiece 200 is installed on the connecting assembly 12, the axis of the workpiece 200 extends along a first direction, and the rotating drive component 11 drives the workpiece 200 to rotate via the connecting assembly 12.
[0027] The supporting mechanism 20 includes two parallel supporting rollers 21, which extend along a first direction and are spaced apart along a second direction perpendicular to the first direction. The two supporting rollers 21 are configured to jointly support the workpiece 200. In this embodiment, the supporting mechanism 20 may further include a bracket 22, which is spaced apart from the connecting assembly 12 along the first direction. The two supporting rollers 21 are rotatably connected to the bracket 22, and each supporting roller 21 can rotate about its own axis. It is understood that the axis of each supporting roller 21 is lower than the axis of the connecting assembly 12 along a third direction, so that after the workpiece 200 is connected to the connecting assembly 12, the sidewall of the workpiece 200 abuts against the two supporting rollers 21. When the rotation drive 11 drives the workpiece 200 to rotate through the connecting assembly 12, both supporting rollers 21 rotate along their own axes.
[0028] The pressing mechanism 30 includes a pressing drive 31 and a pressing element 32. The pressing drive 31 is spaced apart from the support roller 21 along a second direction. The pressing element 32 is connected to the pressing drive 31. The pressing drive 31 drives the pressing element 32 to move closer to or away from the support roller 21 to press or release the workpiece 200. The pressing drive 31 can be a rotary telescopic cylinder, etc., and the pressing element 32 can be a rod-shaped or plate-shaped structure. When pressing the workpiece 200, the pressing drive 31 first drives the pressing element 32 to rotate around a third direction, so that the end of the pressing element 32 away from the pressing drive 31 rotates to above the support roller 21. Then, the pressing drive 31 drives the pressing element 32 to move towards the support roller 21 along a third direction until the pressing element 32 abuts against the workpiece 200. When the workpiece 200 is released, the pressure drive 31 first drives the pressure member 32 to move away from the workpiece 200 along the third direction, and then drives the pressure member 32 to rotate around the third direction, so that the pressure member 32 can avoid the workpiece 200, which is convenient for subsequent grinding of the workpiece 200.
[0029] The pushing mechanism 40 includes a pushing drive 41 and a pushing member 42. The pushing drive 41 is spaced apart from the bearing roller 21 along a first direction. The pushing member 42 is connected to the pushing drive 41. The pushing drive 41 drives the pushing member 42 to move closer to or away from the bearing roller 21, so that the pushing member 42 pushes the workpiece 200 on the bearing roller 21 towards the connecting assembly 12, or moves the pushing member 42 away from the workpiece 200. The pushing drive 41 can be a rotary telescopic cylinder, etc., and the pushing member 42 can be a strip-shaped or plate-shaped structure. When pushing the workpiece 200, the pushing drive 41 first drives the pushing member 42 to rotate around the first direction, so that the end of the pushing member 42 away from the pushing drive 41 corresponds to the workpiece 200 in the first direction. Then, the pushing drive 41 drives the pushing member 42 to move toward the workpiece 200, so that the pushing member 42 pushes the workpiece 200 toward the connecting assembly 12 to a preset position, so that the workpiece 200 is connected to the connecting assembly 12. When the workpiece 200 is released, the pusher drive 41 first drives the pusher 42 to move away from the workpiece 200 along the first direction, and then drives the pusher 42 to rotate around the first direction so that the pusher 42 avoids the workpiece 200. By setting the pusher mechanism 40, the position of the workpiece 200 in the first direction can be standardized, improving the consistency of the connection between the workpiece 200 and the connecting assembly 12.
[0030] The grinding mechanism 50 is arranged adjacent to the supporting mechanism 20. The grinding mechanism 50 includes a grinding component 51, which is used to grind the workpiece 200. The grinding component 51 can be sandpaper, polishing cotton, or other objects used for grinding and polishing.
[0031] The grinding equipment 100 provided in this application embodiment can carry a workpiece 200 through two support rollers 21 in the support mechanism 20. The pusher 41 in the pusher mechanism 40 drives the pusher 42 to push the workpiece 200 toward the connecting assembly 12 in the rotating mechanism 10, thereby connecting the workpiece 200 to the connecting assembly 12. When grinding the end of the workpiece 200, the pusher 41 drives the pusher 42 away from the workpiece 200 to avoid obstruction. The pressure drive 31 in the pressure mechanism 30 drives the pressure member 32 to press the workpiece 200 on the support rollers 21. The grinding member 51 in the grinding mechanism 50 abuts against the end of the workpiece 200. The rotating drive 11 drives the workpiece 200 to rotate through the connecting assembly 12, thereby grinding the end of the workpiece 200. When grinding the side wall of workpiece 200, the pressure drive 31 drives the pressure member 32 away from workpiece 200 to avoid the workpiece 200, the grinding member 51 abuts against the side wall of workpiece 200, and the rotation drive 11 drives the workpiece 200 to rotate through the connecting assembly 12, thereby grinding the side wall of workpiece 200.
[0032] The grinding equipment 100 provided in this application embodiment can support the workpiece 200 through the bearing mechanism 20, drive the workpiece 200 to rotate through the rotating mechanism 10, improve the consistency of the installation position of the workpiece 200 through the pushing mechanism 40, and press the workpiece 200 by the pressing mechanism 30 when the grinding part 51 grinds the end of the workpiece 200, thus preventing the workpiece 200 from bending and deforming during the grinding process and improving the grinding yield. When grinding the side wall of the workpiece 200, the two bearing rollers 21 can support the workpiece 200, preventing the workpiece 200 from bending and deforming during the grinding process and improving the grinding yield. The rotating drive 11 drives the workpiece 200 to rotate continuously during the grinding process through the connecting assembly 12, which can effectively improve the grinding uniformity.
[0033] In some embodiments, see Figure 2 and Figure 3 The connecting assembly 12 includes a rotating shaft 121, a first elastic element 122, an elastic collet 123, and a collet cap 124. The rotating shaft 121 is connected to the rotary drive 11 and extends along a first direction. A receiving groove 1211 is formed at the end of the rotating shaft 121 away from the rotary drive 11. The first elastic element 122 is disposed in the receiving groove 1211 and abuts against the bottom of the groove. The elastic collet 123 is inserted into the receiving groove 1211 and extends out of the receiving groove 1211, and the elastic collet 123 abuts against the first elastic element 122. A clamping hole 1231 extending in a first direction is provided. A collet cap 124 with a movable sleeve 125 is provided at the end of the rotating shaft 121 away from the rotating drive member 11 and abuts against the elastic collet 123. The clamping hole 1231 is used to accommodate one end of the workpiece 200. The collet cap 124 moves toward the rotating drive member 11 to push the elastic collet 123 to clamp the workpiece 200. The first elastic member 122 is used to push the elastic collet 123 to move in the first direction when the collet cap 124 moves away from the rotating drive member 11, so that the elastic collet 123 releases the workpiece 200.
[0034] The rotating shaft 121 can be a columnar structure, and the first elastic element 122 can be a spring, etc. In this embodiment, the rotating shaft 121, the receiving groove 1211, the elastic collet 123, the clamping hole 1231, and the collet cap 124 are all coaxially arranged. When installing the workpiece 200, one end of the workpiece 200, such as the connecting part 201, is inserted into the clamping hole 1231 and the receiving groove 1211. Then, the collet cap 124 is moved towards the rotary drive member 11 in the first direction. The collet cap 124 pushes against the elastic collet 123 and moves synchronously. The elastic collet 123 can clamp the workpiece 200, thus completing the installation of the workpiece 200. When disassembling workpiece 200, the collet cap 124 is moved away from the rotary drive member 11 along the first direction. The collet cap 124 moves away from the elastic collet 123, and the first elastic member 122 pushes the elastic collet 123 away from the rotary drive member 11 along the first direction. The elastic collet 123 then releases the workpiece 200, allowing it to be removed from the receiving groove 1211. In this embodiment, to improve the stability of the elastic collet 123 in holding the workpiece 200, the collet cap 124 can be threaded to the rotating shaft 121, or other connection methods can be used to limit the position of the collet cap 124.
[0035] In some embodiments, see Figure 2 and Figure 3 The receiving groove 1211 is provided with an inclined inner wall 1212, which is connected to the opening of the receiving groove 1211. The inclined inner wall 1212 gradually moves away from the axis of the rotating shaft 121 along a first direction, and the elastic collet 123 abuts against the inclined inner wall 1212. When the collet cap 124 pushes the elastic collet 123 to move towards the rotating drive member 11 along the first direction, the elastic collet 123 gradually moves towards the axis of the rotating shaft 121 under the guidance of the inclined inner wall 1212, thereby clamping the workpiece 200. When the collet cap 124 moves away from the rotating drive member 11 along the first direction, the first elastic member 122 pushes the elastic collet 123 to move away from the rotating drive member 11 along the first direction, and the elastic collet 123 can move gradually away from the axis of the rotating shaft 121 along the inclined inner wall 1212, thereby releasing the workpiece 200.
[0036] In some embodiments, see Figure 2 and Figure 3The connecting assembly 12 also includes a movable sleeve 125, a baffle 126, and a second elastic member 127. The movable sleeve 125 is disposed on the side of the collet cap 124 near the rotary drive member 11 and is also disposed on the rotating shaft 121. The movable sleeve 125 is connected to the collet cap 124. The movable sleeve 125 has a receiving cavity 1251 on the side facing the rotating shaft 121. The baffle 126 is sleeved on the rotating shaft 121 and disposed in the receiving cavity 1251. The second elastic member 127 is disposed in the receiving cavity 1251 and sleeved on the rotating shaft 121. The two ends of the second elastic member 127 abut against the inner wall of the receiving cavity 1251 and the baffle 126, respectively. The elasticity of the second elastic member 127 is greater than the elastic force of the first elastic member 122. The second elastic member 127 is used to push the movable sleeve 125 toward the rotary drive member 11.
[0037] The movable sleeve 125 is generally a tubular structure. The movable sleeve 125 is located on the rotating shaft 121. The cross-section of the receiving cavity 1251 perpendicular to the first direction is an annular structure. The baffle 126 is generally an annular structure. The second elastic element 127 can be a spring, etc. When installing workpiece 200, a force is first applied to the movable sleeve 125 to drive it to move away from the rotary drive member 11 along a first direction. The movable sleeve 125 drives the collet cap 124 to move away from the rotary drive member 11 along the first direction. The first elastic member 122 pushes the elastic collet 123 to move along the first direction. At this time, workpiece 200 can be inserted into the clamping hole 1231 and the receiving groove 1211. Then, the force applied to the movable sleeve 125 is removed. The second elastic member 127 pushes the movable sleeve 125 to move towards the rotary drive member 11 along the first direction. The movable sleeve 125 drives the collet cap 124 to move towards the rotary drive member 11 along the first direction. The collet cap 124 pushes the elastic collet 123 to move towards the rotary drive member 11 along the first direction, thereby causing the elastic collet 123 to clamp workpiece 200. When removing workpiece 200, a force is applied to the movable sleeve 125 to drive it to move away from the rotary drive member 11 along the first direction.
[0038] In some embodiments, see Figure 2 and Figure 3 The rotating mechanism 10 also includes a loosening assembly 13, which includes a loosening drive 131 and a traction member 132. The loosening drive 131 is located near the rotating shaft 121, and the traction member 132 is connected to the loosening drive 131. An annular groove 1252 is provided on the outer wall of the movable sleeve 125. One end of the traction member 132 away from the loosening drive 131 is mounted in the annular groove 1252. The loosening drive 131 drives the traction member 132 to move along a first direction, so that the traction member 132 pushes the movable sleeve 125 away from the rotating drive 11 along the first direction.
[0039] The material loosening drive component 131 can be a telescopic cylinder, etc., and the traction component 132 can be an irregularly shaped structure. The end of the traction component 132 corresponding to the annular groove 1252 is approximately U-shaped and inserted into the annular groove 1252, corresponding to the side wall of the annular groove 1252 in the first direction. It can be understood that the traction component 132 does not contact the bottom of the annular groove 1252 to avoid friction between the movable sleeve 125 and the traction component 132 when rotating. The material loosening drive component 131, through the traction component 132, can drive the movable sleeve 125 to reciprocate along the first direction, thereby realizing the automatic connection and disassembly of the connecting assembly 12 and the workpiece 200. After the connecting assembly 12 and the workpiece 200 are connected, the traction component 132 is spaced apart from the side wall of the annular groove 1252 to avoid friction between the side wall of the annular groove 1252 and the traction component 132 when the movable sleeve 125 rotates.
[0040] In some embodiments, see Figure 2 and Figure 3 The workpiece 200 includes a connecting portion 201 and a grinding portion 202 connected together. The connecting portion 201 has a blind groove 2011. The connecting assembly 12 also includes a positioning pin 128, which is disposed in a receiving groove 1211 and coaxially arranged with a rotating shaft 121. The positioning pin 128 is used to insert into the blind groove 2011 of the workpiece 200 to position the workpiece 200. Because the connecting portion 201 of the workpiece 200 has a blind groove 2011, the connecting portion 201 is generally tubular. If the connecting portion 201 of the workpiece 200 is only clamped by the elastic collet 123, it is easy to cause the connecting portion 201 to be deformed by compression. By setting the positioning pin 128, not only can the workpiece 200 be positioned by inserting into the blind groove 2011, but the connecting portion 201 can also be internally supported to avoid deformation of the connecting portion 201 caused by the clamping force of the elastic collet 123.
[0041] In some embodiments, see Figure 2 and Figure 4 The pressing mechanism 30 also includes two pressing rollers 33, both of which are rotatably connected to the pressing member 32 around a first direction and are spaced apart. When the pressing drive member 31 drives the pressing member 32 to move toward the support roller 21, both pressing rollers 33 abut against the workpiece 200. In this embodiment, the axes of the two pressing rollers 33 are spaced apart along a second direction, and the midpoint between the axes of the two pressing rollers 33 and the midpoint between the axes of the two support rollers 21 are spaced apart along a third direction. Thus, the workpiece 200 can be fixed around the workpiece 200 by the two support rollers 21 and the two pressing rollers 33. When the workpiece 200 rotates around its axis, the two support rollers 21 and the two pressing rollers 33 can rotate with the workpiece 200.
[0042] In some embodiments, see Figure 2 and Figure 4The bearing roller 21, which abuts against the side wall of the workpiece 200, is provided with a first flexible element 23, and the pressure roller 33, which abuts against the side wall of the workpiece 200, is provided with a second flexible element 34. Both the first flexible element 23 and the second flexible element 34 are used to flexibly abut against the workpiece 200. By providing the first flexible element 23 on the side wall of the bearing roller 21 and the second flexible element 34 on the side wall of the pressure roller 33, scratches, indentations, or other surface damage caused by hard contact can be avoided. In this embodiment, the first flexible element 23 can be made of Teflon or similar materials, and the second flexible element 34 can be made of urethane or similar materials.
[0043] In some embodiments, see Figure 2 and Figure 3 The pusher 42 has a positioning groove 421 on one side that abuts against the workpiece 200. The positioning groove 421 is used to accommodate the end of the workpiece 200 when the pusher 42 abuts against the workpiece 200, thereby positioning the workpiece 200. The structure of the positioning groove 421 is adapted to the cross-sectional structure of the workpiece 200. By providing the positioning groove 421 on the pusher 42, the end of the workpiece 200 can be accommodated in the positioning groove 421 when the pusher 42 pushes against the workpiece 200, ensuring that the workpiece 200 always maintains the correct posture and position during the pushing process. By limiting the workpiece 200 through the positioning groove 421, the offset or shaking of the workpiece 200 during the pushing process can be effectively reduced, avoiding processing errors caused by inaccurate positioning, and ensuring that the workpiece 200 accurately reaches the predetermined position each time it is pushed.
[0044] In some embodiments, see Figure 1 and Figure 2 The grinding mechanism 50 also includes a moving drive 52 and a grinding drive 53. The moving drive 52 is arranged adjacent to the carrying roller 21, and the grinding drive 53 is connected to the moving drive 52. The grinding element 51 is connected to the grinding drive 53. The moving drive 52 is configured to drive the grinding drive 53 and the grinding element 51 to move, so that the grinding element 51 abuts against the workpiece 200. The grinding drive 53 is configured to drive the grinding element 51 to rotate, so as to grind the workpiece 200. The moving drive 52 can be a robotic arm, etc., and the grinding drive 53 can be a rotary motor, rotary cylinder, etc. The moving drive 52 can drive the grinding drive 53 and the grinding element 51 to move freely in three-dimensional space, so that the grinding element 51 can grind the end or the side of the workpiece 200. The grinding drive 53 can drive the grinding element 51 to rotate, so as to achieve continuous grinding, thereby significantly improving grinding efficiency. It is understandable that when grinding the end of the workpiece 200, the grinding drive 53 drives the grinding component 51 to rotate in the opposite direction to the rotation of the workpiece 200.
[0045] The working process of the grinding equipment 100 provided in this embodiment is roughly as follows:
[0046] First, the loosening drive 131 of the loosening assembly 13 drives the traction member 132 to move along the first direction, thereby pushing the movable sleeve 125 to move away from the rotating drive 11 along the first direction. The movable sleeve 125 drives the collet cap 124 to move synchronously. The first elastic member 122 pushes the elastic collet 123 to move away from the rotating drive 11 along the first direction, and the elastic collet 123 is in the open state.
[0047] Then, the workpiece 200 is placed on the two support rollers 21, and the connecting part 201 of the workpiece 200 is positioned opposite to the connecting assembly 12. The pushing drive member 41 of the pushing mechanism 40 first drives the pushing member 42 to rotate around the first direction, so that the end of the pushing member 42 away from the pushing drive member 41 corresponds to the workpiece 200 in the first direction. Then, the pushing drive member 41 drives the pushing member 42 to move toward the workpiece 200, so that the connecting part 201 of the workpiece 200 is inserted into the clamping hole 1231 of the elastic collet 123, and the positioning pin 128 is inserted into the blind hole of the workpiece 200.
[0048] Next, the loosening drive 131 drives the traction member 132 to move toward the rotating drive 11 in the first direction. The second elastic member 127 pushes the movable sleeve 125 to move toward the rotating drive 11 in the first direction. The movable sleeve 125 drives the collet cap 124 to move synchronously. The collet cap 124 pushes the elastic collet 123 to move toward the rotating drive 11. The elastic collet 123 clamps the connecting part 201 of the workpiece 200. In this way, the installation of the workpiece 200 is completed.
[0049] When grinding the end of workpiece 200, the pusher drive 41 first drives the pusher 42 to move away from workpiece 200 along a first direction, and then drives the pusher 42 to rotate around the first direction so that the pusher 42 avoids the workpiece 200. The pressure drive 31 first drives the pressure member 32 to rotate around a third direction so that the two pressure rollers 33 on the pressure member 32 rotate above the support roller 21. Then the pressure drive 31 drives the pressure member 32 to move towards the support roller 21 along a third direction until the two pressure rollers 33 abut against the workpiece 200. The rotation drive 11 drives the connecting assembly 12 to rotate, thereby driving the workpiece 200 to rotate. The moving drive 52 drives the grinding drive 53 and the grinding member 51 to move towards the end of workpiece 200. The grinding member 51 abuts against the workpiece 200. The grinding drive 53 drives the grinding member 51 to rotate, thereby grinding the end of workpiece 200.
[0050] When grinding the side wall of workpiece 200, the pressure drive 31 first drives the pressure member 32 to move away from workpiece 200 along a third direction, and then drives the pressure member 32 to rotate around the third direction, so that the pressure member 32 avoids the workpiece 200. The moving drive 52 then drives the grinding drive 53 and the grinding member 51 to move towards the side wall of workpiece 200, thereby grinding the side wall of workpiece 200.
