[0074] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0075] The polishing equipment of this utility model is described below with reference to the accompanying drawings.

[0076] like Figure 1 and Figure 2 As shown, this utility model provides a polishing device, which includes a frame 1, a polishing device 5, a rotating device 2, and a swing adjustment device 3. The polishing device 5 includes an abrasive 51 and a positioning seat 52. The rotating device 2 includes a rotating drive mechanism 21 and a rotating shaft 22. One end of the rotating shaft 22 is connected to the rotating drive mechanism 21, and the other end of the rotating shaft 22 is connected to either the abrasive 51 or the positioning seat 52. The swing adjustment device 3 includes a swing drive mechanism 31 and a swing seat 32. Both ends of the swing seat 32 are movably connected to the frame 1 and the swing drive mechanism 31, respectively. The rotating shaft 22 is disposed on the swing seat 32.

[0077] Specifically, the rotary drive mechanism 21 is driven by and drives the rotary shaft 22 to rotate. The other end of the rotary shaft 22 is connected to either the grinding wheel 51 or the positioning seat 52. When the other end of the rotary shaft 22 is connected to the grinding wheel 51, the workpiece 200 is placed inside the positioning seat 52. The positioning seat 52 is adapted to the grinding wheel 51. When the rotary shaft 22 drives the grinding wheel 51 to rotate, the workpiece 200 on the positioning seat 52 comes into frictional contact with the grinding wheel 51, thereby performing polishing and grinding. When the other end of the rotary shaft 22 is connected to the positioning seat 52, the workpiece 200 is placed on the side of the positioning seat 52 away from the rotary shaft 22. The grinding wheel 51 is placed on the side of the workpiece 200 away from the positioning seat 52. When the rotary shaft 22 drives the workpiece 200 on the positioning seat 52 to rotate, the workpiece 200 on the positioning seat 52 comes into frictional contact with the grinding wheel 51, thereby performing polishing and grinding. Meanwhile, the swing base 32 is oscillatingly connected to the frame 1, and the swing drive mechanism 31 is driven by the swing base 32 and can drive the swing base 32 to swing relative to the frame 1. The rotating shaft 22 and the rotating drive mechanism 21 are both located on the swing base 32, so the swing base 32 drives the rotating shaft 22 to swing, thereby adjusting the deflection angle of the abrasive 51 or the positioning seat 52 connected to the rotating shaft 22. The polishing equipment of this utility model adjusts the deflection angle of the rotating shaft 22 located on the swing base 32 through the swing adjustment device 3, thereby adjusting the direction of the force exerted by the abrasive 51 on each position of the workpiece 200, so that the friction force on each position of the workpiece 200 is consistent, thereby solving the polishing defects caused by uneven polishing force when polishing the workpiece 200, and greatly improving the polishing quality.

[0078] It should be noted that the workpiece 200 is a curved surface product, including convex and concave products. When the workpiece 200 is a convex product, the abrasive 51 is connected to the rotating shaft 22, and the workpiece 200 is placed in the positioning seat 52 that is compatible with the abrasive 51. When the workpiece 200 is a concave product, the positioning seat 52 is connected to the rotating shaft 22, and the workpiece 200 is placed in the positioning seat 52. In this way, the polishing equipment of this utility model embodiment can polish different curved surface products, with a wide range of applications and strong adaptability.

[0079] In one embodiment of this utility model, such as Figure 3 As shown, the workpiece 200 to be polished is a spherical product. The abrasive 51 is mounted on the rotating shaft 22. When polishing the workpiece 200, the forces contacting the edge and center of the workpiece 200 with the abrasive 51 are different, resulting in uneven polishing wear. In this embodiment, the yaw angle of the rotating shaft 22 is adjusted so that the rotating shaft 22 oscillates to... Figure 4As shown by the yaw angle, when the rotating shaft 22 swings to a suitable yaw position, the grinding wheel 51 adapts to various positions of the workpiece 200, thereby adjusting the direction of the force acting on various positions of the workpiece 200, so that the friction force on various positions of the workpiece 200 is consistent, thereby solving the polishing defects caused by uneven polishing force when polishing the workpiece 200, improving processing stability, and improving the polishing quality of the workpiece 200.

[0080] In another embodiment of this utility model, such as Figure 5 As shown, the workpiece 200 to be polished is a product with inner rounded corners. When the workpiece 200 is placed on the positioning seat 52 connected to the rotating shaft 22 and the rotating shaft 22 is vertical, the abrasive tool 51 cannot act on the inner rounded corners of the workpiece 200, resulting in insufficient polishing pressure, small removal volume, a high proportion of incomplete polishing of the inner rounded corners of the workpiece 200, and rapid local wear of the abrasive tool 51, shortening its service life and affecting the polishing quality. This embodiment adjusts the sway angle of the rotating shaft 22 so that the rotating shaft 22 oscillates to... Figure 6 As shown by the yaw angle, when the rotating shaft 22 swings to a suitable yaw position, the grinding wheel 51 can act perpendicularly on the inner rounded corner of the workpiece 200. There is no interference between the grinding wheel and the workpiece 200, so that the pressure of the rotating shaft 22 and the grinding wheel 51 acting on the workpiece 200 is uniform and stable, which improves the removal amount and processing quality, effectively slows down the wear rate of the grinding wheel 51, extends the service life of the grinding wheel 51, and greatly improves the polishing quality.

[0081] In this embodiment of the utility model, the swing base 32 includes a swing bracket 321 and a swing frame 322. The swing bracket 321 is oscillatingly connected to the frame 1, and the end of the swing bracket 321 is connected to the swing frame 322. The rotation shaft 22 is disposed on the swing frame 322, and the swing frame 322 is connected to the swing drive mechanism 31. Figure 1 and Figure 2As shown, the frame 1 is equipped with a mounting shaft 323, and a swing bracket 321 is hung on the mounting shaft 323 and can swing around the mounting shaft 323 as the swing center. The two ends of the swing bracket 321 are respectively connected to the two ends of the swing frame 322, and the connection is stable and reliable, and can drive the swing frame 322 to swing. The rotating shaft 22 is rotatably mounted on the swing frame 322, so that the swing frame 322 can drive the rotating shaft 22 to swing to adjust the swing angle of the rotating shaft 22. In this way, the direction of the force exerted by the abrasive 51 on each position of the workpiece 200 can be quickly adjusted, so that the friction force on each position of the workpiece 200 is consistent, further improving the polishing quality and stability. In a specific embodiment of this utility model, the rotating shaft 22 is set on the swing frame 322, and the swing frame 322 drives the rotating shaft 22 to swing, which reduces the swing weight of the swing seat 32, and the structural design is simple and stable.

[0082] Furthermore, the swing drive mechanism 31 includes a rotation drive assembly 311 and an adjusting rod 312. The adjusting rod 312 is rotatably connected to the rotation drive assembly 311, and the swing base 32 is movably connected to the adjusting rod 312 and reciprocates along the extension direction of the adjusting rod 312. Figure 1 and Figure 2 As shown, the rotation drive assembly 311 is driven to the adjustment rod 312 and is used to drive the adjustment rod 312 to rotate. The adjustment rod 312 is hinged to the rotation drive assembly 311 so that it can swing relative to the rotation drive assembly 311. The swing seat 32 is movably connected to the adjustment rod 312. When it is necessary to adjust the swing angle of the rotating shaft 22, the rotation drive assembly 311 drives the adjustment rod 312 to rotate, so that the adjustment rod 312 drives the swing seat 32 to move along the extension direction of the adjustment rod 312. This causes the swing seat 32 to swing around the mounting shaft 323 as the swing center. The swing seat 32 drives the rotating shaft 22 to swing, thereby adjusting the swing angle of the rotating shaft 22. This allows the direction of the force exerted by the grinding tool 51 on each position of the workpiece 200 to be adjusted, so that the friction force on each position of the workpiece 200 remains consistent. In a specific embodiment of this utility model, the swing seat 32 is movably connected to the adjusting rod 312 in the swing drive mechanism 31 and moves back and forth along the extension direction of the adjusting rod 312. Under the drive of the rotation drive assembly 311, the swing seat 32 swings. The structure is simple and the adjustment is convenient.

[0083] In the embodiments of this utility model, such as Figure 1 and Figure 2As shown, the swing drive mechanism 31 also includes a moving block 313, which is sleeved on the adjusting rod 312 and threadedly connected to the adjusting rod 312. The moving block 313 is also connected to the swing frame 322. The rotating drive component 3111 drives the adjusting rod 312 to rotate, and the adjusting rod 312 drives the moving block 313 to reciprocate along the extension direction of the adjusting rod 312, so that the moving block 313 can drive the swing frame 322 and the rotating shaft 22 to swing. The transmission is smooth and reliable, and the adjustment flexibility is improved. In addition, the swing drive mechanism 31 also includes a transition block 314, which is disposed on the swing frame 322. The moving block 313 is installed in the transition block 314, so that the moving block 313 can drive the swing frame 322 to swing through the transition block 314, which improves the ease of assembly. The transition block 314 is provided with a relief groove, which is used to avoid the rotation of the moving block 313, effectively preventing the moving block 313 from getting stuck. The structure design is reasonable.

[0084] Furthermore, the rotation drive assembly 311 includes a rotation drive member 3111 and a transition shaft 3112. Both ends of the transition shaft 3112 are connected to the rotation drive member 3111 and the adjusting rod 312, respectively. The adjusting rod 312 is rotatably connected to the rotation drive member 3111. Figure 1 and Figure 2 As shown, the rotation drive 3111 is hinged to the adapter shaft 3112, and the adjusting rod 312 is connected to the adapter shaft 3112. The rotation drive 3111 drives the adapter shaft 3112 to rotate, so that the adapter shaft 3112 drives the adjusting rod 312 to rotate. The adjusting rod 312 rotates and drives the moving block 313 to reciprocate along the extension direction of the adjusting rod 312. The moving block 313 drives the swing frame 322 to swing to adjust the swing angle of the rotating shaft 22. When the swing frame 322 swings, it drives the moving block 313 to generate displacement in the vertical direction. The hinge between the rotation drive 3111 and the adapter shaft 3112 allows the adjusting rod 312 and the adapter shaft 3112 to swing relative to the rotation drive 3111, which effectively prevents the adjusting rod 312 from jamming under force. The structure is reasonably designed and the transmission is smooth and reliable.

[0085] In the embodiments of this utility model, such as Figure 1 and Figure 2As shown, a rotating wheel 3113 is provided at the end of the rotating drive 3111 away from the adapter shaft 3112. A rotating handle 3114 is provided on the rotating wheel 3113. When it is necessary to adjust the swing angle of the rotating shaft 22, the operator can rotate the rotating handle 3114 to drive the rotating wheel 3113 to rotate. The rotating wheel 3113 drives the rotating drive 3111 to rotate, so that the rotating drive 3111 drives the adjusting rod 312 to rotate through the adapter shaft 3112, making the adjustment flexible and convenient. In addition, a swing pointer 33 is provided on the mounting shaft 323. The swing pointer 33 is used to swing synchronously with the swing bracket 321. A scale 34 is provided on the frame 1. The scale 34 has a swing angle marking structure. When the operator adjusts the swing angle of the rotating shaft 22, the swing pointer 33 can swing relative to the scale 34 to indicate the swing angle of the rotating shaft 22, which makes it easy for the operator to observe and determine the swing position of the rotating shaft 22, further improving the convenience of adjustment.

[0086] Furthermore, the rotary drive mechanism 21 includes a rotary drive component and a rotary transmission assembly. The rotary drive component is driven to the rotary shaft 22 through the rotary transmission assembly. The rotary drive component can be a motor as used in the prior art, and the rotary transmission assembly can be a transmission belt and a synchronous pulley as used in the prior art. This allows the rotary drive component to drive the rotary shaft 22 to rotate through the rotary transmission assembly. The rotary shaft 22 drives the grinding wheel 51 or the positioning seat 52 connected to the rotary shaft 22 to rotate, thereby enabling the grinding wheel 51 to polish and grind the workpiece 200.

[0087] Those skilled in the art will understand that the rotary drive mechanism 21 of this application is not limited to the aforementioned rotary drive component being a motor and the rotary transmission assembly being a transmission belt and synchronous pulley. The rotary transmission assembly may also be a transmission chain, transmission gear, or other structural forms capable of driving the rotary shaft 22 to rotate, all of which should fall within the scope of protection of this application. It should be noted that the structures for driving the rotary shaft 22 to rotate are well known to those skilled in the art and are not part of the core improvement of this application; therefore, they will not be described in detail here.

[0088] In this embodiment of the invention, the polishing equipment further includes a rotary pressing device 4. The rotary pressing device 4 includes a rotary drive mechanism 41, a rotary frame 42, and a pressing rod 43. The two ends of the rotary frame 42 are respectively connected to the rotary drive mechanism 41 and the pressing rod 43. The pressing rod 43 is arranged opposite to the rotating shaft 22. Figure 7As shown, the rotary drive mechanism 41 is driven to one end of the rotary frame 42, and the other end of the rotary frame 42 is driven to the top pressure rod 43. The top pressure rod 43 presses against the polishing device 5, and the top pressure rod 43 is used to stably contact the workpiece 200 with the abrasive 51. The rotary drive mechanism 41 is used to drive the top pressure rod 43 to make a circular motion through the rotary frame 42, so that the workpiece 200 makes a periodic circular motion relative to the abrasive 51, thereby making the abrasive 51 polish and grind the surface of the workpiece 200. The circular motion of the workpiece 200 relative to the abrasive 51 increases the polished area of ​​the workpiece 200, making the surface polishing of the workpiece 200 more uniform and improving the polishing quality.

[0089] In this embodiment of the utility model, the rotary drive mechanism 41 includes a rotary drive assembly 411 and an eccentric adjustment assembly 412. The eccentric adjustment assembly 412 includes a rotating wheel 4121, an eccentric wheel 4122 and a connecting shaft 4123. The rotating wheel 4121 is connected to the rotary drive assembly 411. The eccentric wheel 4122 is disposed on the rotating wheel 4121 and is eccentrically disposed relative to the axis of the rotating wheel 4121. The two ends of the connecting shaft 4123 are respectively connected to the eccentric wheel 4122 and the rotary frame 42.

[0090] like Figure 7 , Figure 8 and Figure 9 As shown, the rotary drive assembly 411 is driven to rotate the wheel 4121. The eccentric wheel 4122 is eccentrically mounted on the wheel 4121 and is connected to the rotary frame 42 via the connecting shaft 4123. The rotary drive assembly 411 drives the wheel 4121 to rotate, causing the eccentric wheel 4122 to make periodic circular motion around the axis of the wheel 4121. The eccentric wheel 4122 drives the top pressure rod 43 to make circular motion through the connecting shaft 4123 and the rotary frame 42, thereby causing the workpiece 200 to make circular motion relative to the grinding mold 51, which improves the polishing uniformity and polishing quality.

[0091] Furthermore, such as Figure 8 and Figure 9As shown, the rotating wheel 4121 has an adjustment groove 4124, and an adjustment slider 4125 is provided in the adjustment groove 4124 to slide in cooperation with the adjustment groove 4124. The adjustment slider 4125 is connected to the eccentric wheel 4122. By moving the adjustment slider 4125, the adjustment slider 4125 drives the eccentric wheel 4122 to slide back and forth along the extension direction of the adjustment groove 4124, thereby adjusting the eccentric position of the eccentric wheel 4122 relative to the axis of the rotating wheel 4121. This allows the operator to adjust the eccentric position of the eccentric wheel 4122 according to the size of the workpiece 200 and the amount of material to be removed when polishing the workpiece 200. By adjusting the eccentric position of the eccentric wheel 4122, the top pressure rod 43 can make circular motions of different radii. When the radius of the circular motion is larger, the size of the workpiece 200 that can be polished is larger and the amount of material removed is greater. When the radius of the circular motion is smaller, it is suitable for polishing smaller workpieces 200, thus improving the versatility and universality of the polishing equipment.

[0092] In the embodiments of this utility model, such as Figure 8 and Figure 9 As shown, an adjusting screw 4126 is provided in the adjusting groove 4124. The adjusting screw 4126 is threadedly connected to the adjusting slider 4125. When it is necessary to adjust the eccentric position of the eccentric wheel 4122, the operator can rotate the adjusting screw 4126 to make the adjusting screw 4126 drive the adjusting slider 4125 to slide in the adjusting groove 4124. The adjusting slider 4125 drives the eccentric wheel 4122 to move relative to the axis of the rotating wheel 4121 to adjust the eccentric position of the eccentric wheel 4122, thereby adjusting the radius of the circular motion of the top pressure rod 43. The adjustment is convenient and quick. In addition, a positioning piece 4127 is provided at the end of the adjusting groove 4124. The adjusting screw 4126 passes through the positioning piece 4127 and is threadedly connected to the adjusting slider 4125. The positioning piece 4127 serves to fix the adjusting screw 4126, making the structure stable and reliable and improving the convenience of adjustment.

[0093] In the embodiments of this utility model, such as Figure 7 As shown, the rotary drive assembly 411 includes a rotary drive component 4111, a rotary transmission assembly, and a rotating column 4112. The rotary drive component 4111 is driven to the rotating column 4112 through the rotary transmission assembly. The rotary drive component 4111 can be a motor as used in the prior art, and the rotary transmission assembly can be a transmission belt and a synchronous pulley as used in the prior art, so that the rotary drive component 4111 can drive the rotating column 4112 to rotate through the rotary transmission assembly. The rotating wheel 4121 is set on the rotating column 4112, and the rotating column 4112 drives the rotating wheel 4121 to rotate, which in turn causes the rotating wheel 4121 to drive the top pressure rod 43 to perform circumferential motion through the eccentric wheel 4122, the connecting shaft 4123, and the rotary frame 42.

[0094] Those skilled in the art will understand that the rotary drive assembly 411 of this application is not limited to the aforementioned structure of the rotary drive component 4111 being a motor and the rotary transmission assembly being a transmission belt and synchronous pulley. It can also be a transmission chain, transmission gear, or other structural forms capable of driving the rotating column 4112 to rotate, all of which should fall within the scope of protection of this application. It should be noted that the structures for driving the rotating column 4112 to rotate using the rotary drive component 4111 are well known to those skilled in the art and are not part of the core improvement of this application; therefore, they will not be described in detail here.

[0095] In this embodiment of the invention, the rotary pressing device 4 further includes a pressing drive component 44, which is connected to the rotary frame 42 and set at an angle. Figure 15 As shown, the top pressure drive 44 is mounted on the rotary frame 42 and is inclined relative to the rotary frame 42. The top pressure drive 44 is driven to the rotary frame 42 and is used to drive the top pressure rod 43 to press down in a direction close to the workpiece 200 through the rotary frame 42, so that the top pressure rod 43 can apply downward pressure to the workpiece 200 and thus make the workpiece 200 and the abrasive 51 in stable contact, which facilitates the abrasive 51 to polish the workpiece 200, improves the polishing quality and improves the polishing efficiency.

[0096] Furthermore, such as Figure 15 As shown, a pressure sensor 45 is installed on the rotary frame 42. The pressure sensor 45 is used to detect the downward pressure applied by the top pressure rod 43 to the workpiece 200, so that the operator can control and adjust the downward pressure of the top pressure rod 43, the eccentric position of the eccentric wheel 4122, etc. according to the detection results of the pressure sensor 45, thereby ensuring constant pressure and stable removal amount during the polishing process, and improving the polishing quality and dimensional yield of the workpiece 200.

[0097] Those skilled in the art will understand that the position of the pressure sensor 45 is not limited to being located on the rotary frame 42, but can also be located on the top pressure rod 43. The pressure sensor 45 only needs to be located at the output end of the top pressure drive 44, and be able to detect the downward pressure applied by the top pressure drive 44 to the workpiece 200.

[0098] In this embodiment of the utility model, the rotary frame 42 includes a rotary support 421, a transition support 422, an adjusting support 423, and a mounting support 424. The transition support 422 includes a first transition plate 4221 and a second transition plate 4222. The two ends of the rotary support 421 are respectively connected to the connecting shaft 4123 and the first transition plate 4221, and the first transition plate 4221 is hinged to the rotary support 421. The second transition plate 4222 is vertically arranged on the first transition plate 4221. The two ends of the adjusting support 423 are respectively connected to the first transition plate 4221 and the mounting support 424. The top pressure rod 43 is connected to the mounting support 424. The rotary support 421 is provided with an inclined mounting plate 4211.

[0099] like Figure 15 As shown, the top pressure drive 44 is mounted on the mounting plate 4211 and driven to the end of the second adapter plate 4222 away from the first adapter plate 4221. This allows the top pressure drive 44 to drive the second adapter plate 4222 to apply downward pressure. The second adapter plate 4222 then sequentially drives the first adapter plate 4221, the adjusting bracket 423, the mounting bracket 424, and the top pressure rod 43 to press down. This causes the top pressure rod 43 to apply downward pressure to the workpiece 200 and the abrasive 51, thereby stabilizing the contact between the workpiece 200 and the abrasive 51, improving the stability of the processing, and thus improving the polishing quality.

[0100] Furthermore, such as Figure 15 As shown, the pressure sensor 45 is mounted on the adjusting bracket 423. The adjusting bracket 423 and the mounting bracket 424 are connected by fasteners. The operator can adjust the position of the mounting bracket 424 relative to the adjusting bracket 423 by rotating the fasteners. The top pressure rod 43 is connected to the mounting bracket 424 by fasteners. The operator can adjust the height of the top pressure rod 43 by rotating the fasteners. The adjustment is flexible and convenient, so that the top pressure rod 43 can be used to press the workpiece 200 of different shapes and sizes, which improves the versatility and universality of the equipment.

[0101] In this embodiment of the utility model, the rotary pressing device 4 further includes a limiting component 46, which includes a limiting frame 461, a guide slider 462, a connecting block 463, and a limiting block 464. The limiting frame 461 is located below the rotary support 421. The guide slider 462 is slidably located within the limiting frame 461 and can slide back and forth within the limiting frame 461 along the length direction of the rotary support 421. The connecting block 463 is located on the guide slider 462 and rotatably passes through the rotary support 421. The limiting block 464 is connected to the connecting block 463 and is located on the side of the rotary support 421 opposite to the limiting frame 461.

[0102] like Figure 16As shown, the limiting block 464 is used in conjunction with the connecting block 463 to limit the vertical displacement of the rotary support 421, preventing the rotary support 421 from falling off the limiting frame 461 when it is rotating or when the polishing vibration is too large. The structure is stable and reliable. The connecting block 463 can also support the rotary support 421, further improving the stability of the structure. In addition, the guide slider 462 can only slide along the length direction of the rotary support 421 within the limiting frame 461 to limit the displacement of the rotary support 421 in the width direction. This ensures that the rotation center of the connecting shaft 4123, the connection between the connecting block 463 and the rotary support 421, and the axis of the rotating shaft 22 are on the same plane, further improving the processing stability.

[0103] In this embodiment of the invention, when the workpiece 200 to be polished is a convex product, the abrasive 51 is connected to the rotating shaft 22, and a polishing surface 511 is formed on the side of the abrasive 51 facing the workpiece 200. The shape of the polishing surface 511 is adapted to the surface of the workpiece 200. This embodiment does not limit the shape of the polishing surface 511, as long as it allows for polishing and grinding of the surface of the workpiece 200. Figure 12 As shown, the polishing surface 511 is recessed on the side of the grinding wheel 51 facing away from the rotating shaft 22. Multiple chip removal grooves 512 are provided on the polishing surface 511, and the multiple chip removal grooves 512 are circumferentially spaced on the polishing surface 511. The polishing surface 511 is used to rub the surface of the workpiece 200 to polish and grind the workpiece 200. The chip removal grooves 512 are used to discharge the polishing liquid and the chips of the workpiece 200 from the grinding wheel 51. The circumferentially spaced arrangement of the multiple chip removal grooves 512 allows the polishing liquid in the multiple chip removal grooves 512 to be quickly connected and evenly distributed in each chip removal groove 512, which improves the uniformity of the distribution of the polishing liquid and further improves the polishing quality. Moreover, one end of the chip removal groove 512 extends to the edge of the polishing surface 511. When the grinding wheel 51 rotates, it can quickly discharge the chips of the workpiece 200 from the polishing surface 511, resulting in good chip removal effect and effectively preventing chip accumulation.

[0104] Furthermore, the circumferentially spaced arrangement of multiple chip removal grooves 512 effectively reduces the number of grooves 512 compared to the spiral arrangement of chip removal grooves 512 in the prior art, thus reducing the frequency of the edge of the workpiece 200 sinking into the chip removal grooves 512. This effectively prevents the workpiece 200 from cracking during polishing. Moreover, the extension direction of the chip removal grooves 512 is perpendicular to the rotation direction of the polishing surface 511, increasing the cutting force on the workpiece 200 and further improving polishing efficiency. In addition, the abrasive 51 is made of aluminum alloy, which has advantages such as good heat dissipation, high hardness, and low cost. This results in fewer burrs generated during polishing of the workpiece 200, improving the polishing brightness, enhancing polishing quality, and reducing costs.

[0105] Furthermore, the polishing equipment also includes a top pressure fixture 6, on the side of the top pressure fixture 6 facing the abrasive 51, forming a pressing surface 61, which is adapted to the polishing surface 511. For example... Figure 11 and Figure 13 As shown, the pressing surface 61 faces the polishing surface 511 and is adapted to the polishing surface 511. The top pressure rod 43 acts on the top pressure fixture 6. The workpiece 200 is placed between the pressing surface 61 and the polishing surface 511, so that the top pressure rod 43 presses the workpiece 200 onto the polishing surface 511 through the top pressure fixture 6, which improves the stability of the contact between the workpiece 200 and the polishing surface 511 and improves the polishing uniformity. In addition, multiple spaced placement slots 62 are provided on the pressing surface 61. Each placement slot 62 is used to place the workpiece 200, so that multiple workpieces 200 can be placed on the pressing surface 61 at the same time, and then multiple workpieces 200 can be polished at the same time, which improves the polishing efficiency.

[0106] Furthermore, the pressing rod 43 includes a rod body 431 and a hinge seat 432. Both ends of the rod body 431 are connected to the rotating frame 42 and the hinge seat 432 respectively. The hinge seat 432 is provided with multiple spaced-apart ejector pins 433, which press against the pressing fixture 6. For example... Figure 14 As shown, the upper end of the rod body 431 is connected to the rotary frame 42, and the lower end of the rod body 431 is hinged to a hinge seat 432. The hinge seat 432 is provided with multiple ejector pins 433. The number of pressing fixtures 6 is the same as the number of ejector pins 433 and they are set one-to-one, so that multiple ejector pins 433 can simultaneously press multiple pressing fixtures 6 onto the grinding mold 51. Each pressing fixture 6 can accommodate multiple workpieces 200 to be processed, so as to simultaneously polish multiple workpieces 200, which greatly improves the polishing efficiency.

[0107] Furthermore, such as Figure 14 As shown, the pressing rod 43 also includes an adapter 434, which is hinged to the rod body 431, so that the rod body 431 is hinged to the hinge seat 432 through the adapter 434, which improves the rotation flexibility of the ejector pin 433 and facilitates multiple ejector pins 433 to simultaneously press multiple pressing fixtures 6, thereby improving processing efficiency.

[0108] Furthermore, such as Figure 10 and Figure 11 As shown, the top pressure fixture 6 is equipped with a bearing 63, and an insert 64 is provided inside the bearing 63 for the ejector pin 433 to extend into. The ejector pin 433 presses the workpiece 200 to be processed onto the polishing surface 511 of the grinding wheel 51 through the insert 64, the bearing 63 and the top pressure fixture 6 in sequence. The insert 64 is used to fit with the ejector pin 433 so that the pressing force of the ejector pin 433 can be applied to the bearing 63 and the top pressure fixture 6 through the insert 64. The bearing 63 is sleeved outside the insert 64 to improve the smoothness of transmission and the stability of structure, thereby improving the polishing quality.
