Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a polishing device. Background Technology

[0002] During the production and processing of components such as smart lock housings, the mounting surfaces need to be polished to ensure the installation accuracy and aesthetics of the smart lock housing.

[0003] Current methods for polishing smart lock housings typically involve the user holding the smart lock housing close to the workpiece for polishing. This method is inefficient and labor-intensive. Furthermore, the user may experience shaking while holding the smart lock housing, resulting in lower polishing precision and posing certain safety hazards. Utility Model Content

[0004] Therefore, it is necessary to provide a polishing device to address the above problems, so as to improve the polishing effect and enhance safety.

[0005] This utility model provides a grinding device, comprising: a grinding assembly including a grinding element; a mounting base disposed at the bottom of the grinding element, the top of the mounting base including a mounting position for mounting a workpiece; a feeding assembly connected to the mounting base and capable of driving the mounting base to move relative to the grinding element, such that the mounting position moves closer to / away from the grinding element; and a locking assembly including a locking member disposed on the mounting base and capable of rising / falling relative to the mounting base, wherein in the fallen state, the locking member can press and fix the workpiece to the mounting base, and the highest point of the locking member is lower than the surface of the workpiece to be ground.

[0006] In the aforementioned grinding device, before grinding, the feed assembly is controlled to drive the mounting base away from the grinding workpiece, ensuring the mounting position is far from the workpiece for easy workpiece installation and preventing user hand contact with the grinding workpiece. Then, the workpiece is placed on the mounting position of the mounting base, and the locking element is lowered to press and fix the workpiece firmly to the mounting base, preventing movement of the workpiece relative to the mounting base during grinding and affecting grinding accuracy. Furthermore, the highest point of the locking element is lower than the surface of the workpiece to be ground, preventing interference between the locking element and the grinding workpiece and affecting the grinding effect. Finally, the feed assembly is controlled to drive... The mounting base moves closer to the workpiece, bringing the workpiece in the mounting position closer until the surface to be ground of the workpiece contacts the bottom of the workpiece. At this point, the surface to be ground of the workpiece can be ground through the bottom of the workpiece. After grinding, the feed assembly is controlled to drive the mounting base away from the workpiece, moving the workpiece away from the workpiece. Finally, the locking mechanism is controlled to rise and remove the workpiece from the mounting position. Grinding workpieces using this device can improve grinding efficiency and effect, reduce safety hazards, and improve safety during use.

[0007] In one embodiment, the locking assembly further includes a locking drive connected to the locking member, the locking drive being capable of driving the locking member to move up and down relative to the mounting base in a preset direction, the preset direction being inclined relative to the vertical direction.

[0008] With this configuration, in the horizontal direction, the locking element will gradually move away from the position where the workpiece is pressed during the upward movement, and will gradually move closer to the position where the workpiece is pressed during the downward movement. This can prevent the locking element from scratching the surface of the workpiece during locking or unlocking, and also make it easier for users to disassemble and assemble the workpiece.

[0009] In one embodiment, the locking drive is disposed at the bottom of the mounting base, and the mounting base is provided with a clearance hole, which is configured to correspond to the mounting hole of the workpiece so that the locking member can pass through the clearance hole and the mounting hole of the workpiece.

[0010] With this configuration, the locking element can also restrict the workpiece from sliding in the horizontal direction when clamping the workpiece, thereby improving the stability and reliability of the workpiece when it is placed in the installation position.

[0011] In one embodiment, the locking member includes an extension and a locking part. One end of the extension is connected to the locking drive member, and the locking part protrudes from the end of the extension away from the locking drive member. The size of the locking part is smaller than or equal to the size of the mounting hole of the workpiece. In the lowered state, the locking part presses against the workpiece.

[0012] This design allows the workpiece to be easily disengaged from the locking part, making it convenient for users to assemble and disassemble the workpiece.

[0013] In one embodiment, the polishing device further includes a base, the mounting seat is disposed on the base, and the feeding assembly includes a lifting drive component disposed on the base, the lifting drive component being connected to the mounting seat and capable of driving the mounting seat to move up and down relative to the base.

[0014] With this configuration, the lifting drive unit allows users to easily control the lifting height of the mounting base and stabilize it at the required height, making operation simple and convenient.

[0015] In one embodiment, the feeding assembly further includes a lifting seat disposed on the base, the mounting seat being disposed on the lifting seat and capable of sliding horizontally relative to the lifting seat; the lifting drive is connected to the lifting seat and is capable of driving the lifting seat and the mounting seat to rise and fall together relative to the base.

[0016] With this configuration, when it is necessary to disassemble or assemble a workpiece, the mounting base can be controlled to slide horizontally away from the grinding workpiece relative to the lifting base, so that the mounting base extends outward rather than being directly below the grinding workpiece, making it more convenient and safer for users to disassemble or assemble workpieces.

[0017] In one embodiment, the feeding assembly further includes a sliding drive member disposed on the lifting seat, the sliding drive member being connected to the mounting base and capable of driving the mounting base to slide horizontally relative to the lifting seat.

[0018] With this configuration, the sliding drive allows users to easily control the sliding distance of the mounting base and stabilize it in the desired position, making operation simple and convenient.

[0019] In one embodiment, the feeding assembly further includes a slide rail disposed on the lifting seat and extending in a horizontal direction, the mounting seat being slidably disposed on the slide rail; and / or, the feeding assembly further includes a guide post disposed on the base and extending in a vertical direction, the lifting seat being slidably disposed on the guide post.

[0020] This configuration ensures the stability of the mounting base during sliding and lifting, guaranteeing the grinding effect.

[0021] In one embodiment, the feed assembly further includes a locking element capable of locking / unlocking the sliding of the mounting base relative to the lifting base.

[0022] This design prevents the mounting base from sliding relative to the lifting base during the grinding process, thus ensuring the grinding effect.

[0023] In one embodiment, the grinding element is a sanding belt, and the grinding assembly further includes two spaced-apart rollers, with the sanding belt wound around the two rollers; the grinding device further includes a drive assembly connected to the grinding assembly, the drive assembly being capable of driving either roller to rotate about its own axis.

[0024] This setup ensures high efficiency and precision in belt sanding, and allows for quick replacement, making it convenient for users. Attached Figure Description

[0041] During the manufacturing process of smart lock housings and other components, the mounting surfaces need to be polished to ensure the installation accuracy and aesthetics of the smart lock housing. Current polishing methods typically involve the user holding the smart lock housing close to the workpiece for polishing, which is inefficient and labor-intensive. Furthermore, the user's handhold may cause vibrations, resulting in lower polishing accuracy and posing certain safety hazards.

[0042] To solve the above problems, such as Figures 1 to 9 As shown, this utility model provides a polishing device to improve polishing effect and enhance safety.

[0043] like Figure 1 and Figure 4 As shown, specifically, the grinding device includes a grinding assembly 1, a mounting base 2, a feeding assembly 3, and a locking assembly 4, wherein: the grinding assembly 1 includes a grinding element 11; the mounting base 2 is located at the bottom of the grinding element 11, and the top of the mounting base 2 includes a mounting position 21 for mounting a workpiece 7; the feeding assembly 3 is connected to the mounting base 2 and can drive the mounting base 2 to move relative to the grinding element 11, so that the mounting position 21 moves closer to or further away from the grinding element 11; the locking assembly 4 includes a locking member 41 located on the mounting base 2 and capable of rising or falling relative to the mounting base 2. In the fallen state, the locking member 41 can press and fix the workpiece 7 to the mounting base 2, and the highest point of the locking member 41 is lower than the surface of the workpiece 7 to be ground.

[0044] In the grinding device provided in this embodiment of the utility model, before grinding, the feed component 3 drives the mounting base 2 to move away from the grinding workpiece 11, so that the mounting position 21 is away from the grinding workpiece 11, so that the user can install the workpiece 7 and avoid the user's hand from contacting the grinding workpiece 11; then the workpiece 7 is placed on the mounting position 21 of the mounting base 2, and the locking member 41 is controlled to descend, so as to press and fix the workpiece 7 to the mounting base 2, preventing the workpiece 7 from moving relative to the mounting base 2 during the grinding process and affecting the grinding accuracy. At this time, the highest point of the locking member 41 is lower than the surface of the workpiece 7 to be ground, so as to avoid the locking member 41 from moving away from the grinding workpiece 11. 1. Interference with the grinding part 11 affects the grinding effect; then, control the feed component 3 to drive the mounting base 2 to move closer to the grinding part 11, so that the workpiece 7 placed on the mounting position 21 is close to the grinding part 11, until the surface to be ground of the workpiece 7 contacts the bottom of the grinding part 11. At this time, the surface to be ground of the workpiece 7 can be ground through the bottom of the grinding part 11; after grinding, control the feed component 3 again to drive the mounting base 2 to move away from the grinding part 11, so that the workpiece 7 placed on the mounting position 21 is away from the grinding part 11. Finally, control the locking part 41 to rise and remove the workpiece 7 from the mounting position 21. Grinding the workpiece 7 with this grinding device can improve grinding efficiency and grinding effect, reduce safety hazards, and improve safety of use; in addition, placing the workpiece 7 on the mounting position 21 above the mounting base 2 can also ensure the stability and reliability of the workpiece 7 on the mounting position 21, prevent the workpiece 7 from falling due to the loosening of the locking part 41, and facilitate the user to install the workpiece 7.

[0045] The grinding device can be used to grind the smart lock housing, where the workpiece 7 is the smart lock housing, and the mounting position 21 is configured to match the structure of the smart lock housing to ensure the stability of the smart lock housing when placed in the mounting position 21 and to ensure the grinding effect. Of course, the grinding device can also be used to grind other structures such as molds and parts, with the mounting position 21 configured to match the structure of the workpiece 7 to be ground.

[0046] like Figures 4 to 6 As shown, the top of the mounting base 2 has two mounting positions 21 arranged side by side, each mounting position 21 for mounting one workpiece 7, thereby enabling simultaneous grinding of the surfaces of two workpieces 7, further improving grinding efficiency. Of course, the top of the mounting base 2 can also be provided with one, three, four or more mounting positions 21 as needed, and this embodiment of the present invention does not impose specific limitations.

[0047] like Figure 1 and Figure 3As shown, in one embodiment, the grinding element 11 is an abrasive belt, and the grinding assembly 1 further includes two spaced rollers 12, with the abrasive belt wound around the two rollers 12. The grinding device also includes a drive assembly 6 connected to the grinding assembly 1, which can drive either roller 12 to rotate around its own axis. Abrasive belt grinding has high processing efficiency and high precision, and can be quickly changed, making it convenient for users to operate. During the grinding process, the drive assembly 6 drives either roller 12 to rotate around its own axis, thereby driving the abrasive belt to move, and through the abrasive belt transmission, the other roller 12 also rotates around its own axis. When the abrasive belt moves, it can grind the surface of the workpiece 7 to be ground. Specifically, the tangents located below the two rollers 12 are parallel to the surface of the workpiece 7 to be ground, so that the bottom of the abrasive belt is parallel to the surface of the workpiece 7 to be ground, in order to ensure the grinding effect.

[0048] like Figure 2 As shown, the grinding assembly 1 also includes two spaced-apart rotating shafts 13, with two rollers 12 connected to the two rotating shafts 13 respectively, and capable of rotating around the axis of the rotating shaft 13. The drive assembly 6 includes a drive motor 61, a first pulley 62, a second pulley 63, and a belt 64. The first pulley 62 is connected to the output shaft of the drive motor 61, the second pulley 63 is connected to either rotating shaft 13, and the belt 64 is wound around the first pulley 62 and the second pulley 63. The drive assembly 6 drives the first pulley 62 to rotate around the axis of the output shaft of the drive motor 61, and drives the second pulley 63 to rotate around the axis of the rotating shaft 13 connected to it via the belt 64, thereby driving the roller 12 connected to it to rotate through the rotating shaft 13.

[0049] Of course, in other embodiments, the grinding component 11 can also be a grinding wheel, grinding block or other grinding tools, and the driving component 6 can also be set as other driving structures, as long as it can drive the grinding component 11 to grind the surface of the workpiece 7 to be ground. This utility model embodiment does not make specific limitations here.

[0050] like Figures 7 to 9As shown, the locking assembly 4 also includes a locking drive 42 connected to the locking member 41. The locking drive 42 can drive the locking member 41 to move up and down relative to the mounting base 2 along a preset direction, which is inclined relative to the vertical direction. The locking drive 42 allows the user to easily control the movement of the locking member 41 along the preset direction and can stabilize the locking member 41 in a descending or ascending state. Operation is simple and convenient, and it ensures the stability and reliability of the locking member 41 when it presses and fixes the workpiece 7 to the mounting base 2. The preset direction is inclined relative to the vertical direction, so that in the horizontal direction, the locking member 41 gradually moves away from the position where the workpiece 7 is pressed during the ascent, and gradually moves closer to the position where the workpiece 7 is pressed during the descent. This prevents the locking member 41 from scratching the surface of the workpiece 7 during locking or unlocking, and also facilitates the user's disassembly and assembly of the workpiece 7. The locking drive 42 can be a cylinder, hydraulic cylinder, or other component capable of driving the locking member 41 to move linearly.

[0051] like Figures 8 to 9 As shown, in one embodiment, when the workpiece 7 is a smart lock housing or similar structure with a mounting hole 71, the locking drive member 42 can be located at the bottom of the mounting base 2. The mounting base 2 has a clearance hole 22, which corresponds to the mounting hole 71 of the workpiece 7, allowing the locking member 41 to pass through both the clearance hole 22 and the mounting hole 71 of the workpiece 7. Taking the X-axis direction as an example (as shown in the figure), when the locking drive member 42 drives the locking member 41 to descend relative to the mounting base 2 along the -X-axis direction, the locking member 41 presses against the edge of the mounting hole 71; when the locking drive member 42 drives the locking member 41 to rise relative to the mounting base 2 along the +X-axis direction, the locking member 41 separates from the workpiece 7. Thus, when the locking member 41 presses against the workpiece 7, it can also restrict the workpiece 7 from sliding in the horizontal direction, further improving the stability and reliability of the workpiece 7 when it is placed in the mounting position 21. Furthermore, the inner wall of the clearance hole 22 is provided with a guide slope 221 extending in a preset direction, which can ensure that the locking member 41 always moves up and down in the preset direction.

[0052] Of course, in other embodiments, when the workpiece 7 does not have a mounting hole 71, the locking drive 42 can also be provided on the side of the mounting base 2. When the locking drive 42 drives the locking member 41 to descend relative to the mounting base 2 in a preset direction, the locking member 41 can press against the outer edge of the workpiece 7.

[0053] like Figure 5 , Figure 8 and Figure 9As shown, in one embodiment, the locking member 41 includes an extension 411 and a locking part 412. One end of the extension 411 is connected to the locking drive member 42, and the locking part 412 protrudes from the end of the extension 411 away from the locking drive member 42. The size of the locking part 412 is smaller than or equal to the size of the mounting hole 71 of the workpiece 7. In the lowered state, the locking part 412 presses against the workpiece 7. The size of the locking part 412 is smaller than or equal to the size of the mounting hole 71 of the workpiece 7, so that the workpiece 7 can be easily disengaged from the locking part 412, facilitating the user's disassembly and assembly of the workpiece 7. Specifically, when the locking drive 42 drives the locking member 41 to rise relative to the mounting base 2 along the +X axis direction, the projection of the locking part 412 on the workpiece 7 is completely located within the mounting hole 71. The user can directly lift the workpiece 7 upward to remove the workpiece 7, or align the mounting hole 71 of the workpiece 7 with the locking part 412 to install the workpiece 7 into the mounting position 21. When the locking drive 42 drives the locking member 41 to descend relative to the mounting base 2 along the -X axis direction, the projection of the locking part 412 on the workpiece 7 is located outside the mounting hole 71, so that the locking part 412 can press against the edge of the mounting hole 71.

[0054] Alternatively, the size of the locking part 412 can be set to be larger than the size of the mounting hole 71 of the workpiece 7, and the size of the extension part 411 can be smaller than or equal to the size of the mounting hole 71 of the workpiece 7. The locking part 41 and the locking drive part 42 can be detachably connected. During the assembly process, the workpiece 7 is first placed in the mounting position 21, and then the extension part 411 is passed through the mounting hole 71 and the clearance hole 22 and connected to the locking drive part 42.

[0055] like Figures 6 to 7 As shown, in one embodiment, each mounting position 21 is provided with two locking components 4 to ensure the stability and reliability of the locking components 4 when pressing and fixing the workpiece 7 to the mounting position 21. When the workpiece 7 is the smart lock housing shown in the figure, the smart lock housing has two opposing mounting holes 71, and the two locking components 4 are also arranged opposite to each other, that is, the preset direction of the two locking components 41 is inclined towards the center of the mounting base 2. Of course, in other embodiments, each mounting position 21 may also have one, three or more locking components 4, as long as the stability and reliability of the locking components 4 when pressing and fixing the workpiece 7 to the mounting position 21 can be guaranteed. This embodiment of the present invention does not impose specific limitations here.

[0056] like Figures 3 to 4As shown, in one embodiment, the grinding device further includes a base 5, a mounting base 2 disposed on the base 5, and a feeding assembly 3 including a lifting drive 31 disposed on the base 5. The lifting drive 31 is connected to the mounting base 2 and can drive the mounting base 2 to rise and fall relative to the base 5. When the lifting drive 31 drives the mounting base 2 to rise relative to the base 5, the surface of the workpiece 7 to be ground can contact the bottom of the grinding element 11, so that the surface of the workpiece 7 to be ground can be ground through the bottom of the grinding element 11. When the lifting drive 31 drives the mounting base 2 to fall relative to the base 5 and away from the grinding element 11, the surface of the workpiece 7 to be ground is separated from the bottom of the grinding element 11, so that the user can easily disassemble and assemble the workpiece 7. Furthermore, during the grinding process, the surface of the workpiece 7 to be ground can be separated from the bottom of the grinding element 11 at any time to stop grinding. The lifting drive 31 allows the user to easily control the lifting height of the mounting base 2 and stabilizes the mounting base 2 at the required height, making operation simple and convenient. The lifting drive component 31 can be a cylinder, hydraulic cylinder, or other component capable of driving the mounting base 2 to move in a straight line. The number of lifting drive components 31 can be one, two, three, four, or more, with multiple lifting drive components 31 arranged at intervals to ensure the mounting base 2 remains balanced during lifting and lowering, thus avoiding impact on grinding accuracy. Alternatively, in other embodiments, the user can manually control the lifting and lowering of the mounting base 2 relative to the base 5, and a locking structure can be used to stabilize the mounting base 2 at different heights.

[0057] like Figure 1 As shown, the polishing component 1 and the driving component 6 can also be located on the base 5, so that the polishing device forms a whole.

[0058] like Figure 1 and Figure 4As shown, the feed assembly 3 also includes a lifting seat 32 disposed on the base 5, and a mounting seat 2 disposed on the lifting seat 32 and capable of sliding horizontally relative to the lifting seat 32; the lifting drive 31 is connected to the lifting seat 32 and can drive the lifting seat 32 and the mounting seat 2 to rise and fall together relative to the base 5. At this time, the lifting drive 31 is indirectly connected to the mounting seat 2 through the lifting seat 32. When it is necessary to disassemble or assemble workpiece 7, the lifting drive 31 first drives the lifting seat 32 and the mounting seat 2 to descend relative to the base 5 and move away from the grinding part 11. Then, the mounting seat 2 is controlled to slide horizontally relative to the lifting seat 32 away from the grinding part 11, so that the mounting seat 2 extends outward rather than being directly below the grinding part 11, making it more convenient and safer for the user to disassemble or assemble workpiece 7. After installation, the mounting seat 2 is first controlled to slide horizontally relative to the lifting seat 32 and approach the grinding part 11, so that the workpiece 7 is directly below the grinding part 11. Then, the lifting drive 31 drives the lifting seat 32 and the mounting seat 2 to rise relative to the base 5 and approach the grinding part 11, so that the surface of workpiece 7 to be ground can contact the bottom of the grinding part 11. Of course, when the mounting seat 2 does not need to slide horizontally, the lifting seat 32 can be removed as needed, and the lifting drive 31 can be directly connected to the mounting seat 2.

[0059] like Figure 4 As shown, the feed assembly 3 also includes a guide post 34 disposed on the base 5 and extending vertically, and the lifting seat 32 is slidably disposed on the guide post 34. Specifically, the lifting seat 32 has a through hole corresponding to the guide post 34, through which the guide post 34 passes, allowing the lifting seat 32 to rise and fall along the guide post 34. The guide post 34 ensures that the lifting seat 32 and the mounting seat 2 always rise and fall vertically, thereby further ensuring the balance and stability of the mounting seat 2 during the rising and falling process, and ensuring the grinding effect. The number of guide posts 34 can be one, two, three, four or more, and multiple guide posts 34 are arranged at intervals along the circumference of the lifting seat 32.

[0060] In one embodiment, the feeding assembly 3 further includes a sliding drive (not shown) disposed on the lifting seat 32. The sliding drive is connected to the mounting base 2 and can drive the mounting base 2 to slide horizontally relative to the lifting seat 32. The sliding drive allows the user to easily control the sliding distance of the mounting base 2 and stabilizes the mounting base 2 in the desired position, making operation simple and convenient. The sliding drive can be a cylinder, hydraulic cylinder, or other component capable of driving the mounting base 2 to move linearly.

[0061] like Figure 4As shown, the feed assembly 3 also includes a sliding seat 36 disposed on the lifting base 32. The sliding seat 36 can slide horizontally relative to the lifting base 32, and the mounting base 2 is fixedly disposed on the sliding seat 36. The mounting base 2 and the sliding seat 36 can rise and fall together with the lifting base 32 relative to the base 5, and the mounting base 2 can also slide horizontally relative to the lifting base 32 together with the sliding seat 36. At this time, the lifting drive 31 is indirectly connected to the mounting base 2 through the lifting base 32 and the sliding seat 36, and the sliding drive is indirectly connected to the mounting base 2 through the sliding seat 36. Of course, the sliding seat 36 can also be omitted as needed, and the mounting base 2 can be directly disposed on the lifting base 32, with the sliding drive directly connected to the mounting base 2.

[0062] Of course, in other embodiments, the user can manually control the sliding seat 36 and the mounting seat 2 to slide horizontally relative to the lifting seat 32. In this case, a handle can be installed on the sliding seat 36 or the mounting seat 2 to facilitate user operation.

[0063] like Figure 4 As shown, the feed assembly 3 also includes a slide rail 33 disposed on the lifting seat 32 and extending horizontally. The sliding seat 36 or the mounting seat 2 is slidably disposed on the slide rail 33. The slide rail 33 ensures that the sliding seat 36 and the mounting seat 2 always slide along the extension direction of the slide rail 33, thereby further ensuring the stability of the mounting seat 2 during the sliding process and ensuring the grinding effect. The number of slide rails 33 can be one, two, or more, with multiple slide rails 33 arranged in parallel at intervals.

[0064] like Figures 3 to 4 As shown, the feed assembly 3 also includes a locking element 35, which can lock or unlock the sliding of the mounting base 2 relative to the lifting base 32. When it is necessary to control the sliding of the mounting base 2 relative to the lifting base 32, the locking element 35 is controlled to be in the unlocked state; when the mounting base 2 slides to the required position, the locking element 35 is controlled to be in the locked state, thereby preventing the mounting base 2 from sliding relative to the lifting base 32 during the grinding process, so as to ensure the grinding effect. The locking element 35 can be set as a bolt structure and is provided on the sliding base 36 or the mounting base 2. When the bolt is loosened to the unlocked state, the end of the bolt facing the lifting base 32 is separated from the lifting base 32, so that the sliding base 36 and the mounting base 2 can slide horizontally relative to the lifting base 32; when the bolt is tightened to the locked state, the end of the bolt facing the lifting base 32 is pressed against the lifting base 32 to restrict the sliding base 36 and the mounting base 2 from sliding horizontally relative to the lifting base 32. Of course, the locking element 35 can also be set as a buckle, pin or other locking structure, as long as it can stabilize the sliding seat 36 and the mounting seat 2 in different positions. This utility model embodiment does not make specific limitations here.

[0065] During use, before grinding, the lifting drive 31 drives the lifting seat 32, sliding seat 36, and mounting seat 2 to descend relative to the base 5. The sliding drive 31 then drives the sliding seat 36 and mounting seat 2 to slide horizontally away from the grinding workpiece 11 relative to the lifting seat 32. Next, the workpiece 7 is placed on the mounting position 21 of the mounting seat 2, and the locking drive 42 drives the locking member 41 to descend along the -X axis to press and fix the workpiece 7 to the mounting seat 2. Finally, the sliding drive 31 drives the sliding seat 36 and mounting seat 2 to slide horizontally relative to the lifting seat 32 to below the grinding workpiece 11, and the lifting drive 31 drives the lifting seat 32... The sliding seat 36 and the mounting seat 2 rise together relative to the base 5, so that the surface of the workpiece 7 to be polished, which is placed on the mounting position 21, contacts the bottom of the polishing part 11. At this time, the drive assembly 6 can drive the polishing part 11 to move and polish the surface of the workpiece 7 to be polished through the bottom of the polishing part 11. After polishing, the lifting drive 31 is controlled again to drive the lifting seat 32, the sliding seat 36 and the mounting seat 2 to fall together relative to the base 5. The sliding drive is controlled to drive the sliding seat 36 and the mounting seat 2 to slide together in the horizontal direction away from the polishing part 11 relative to the lifting seat 32. Finally, the locking drive 42 is controlled to drive the locking part 41 to rise in the +X axis direction and remove the workpiece 7 from the mounting position 21.
