[0058] The specific embodiments of the present invention 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 present invention.

[0059] The polishing equipment of the present invention will now be described with reference to the accompanying drawings.

[0060] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention provides a polishing processing device, wherein the polishing processing device includes:

[0061] The product motion device includes a product support frame 100 and a product arc swing mechanism 300. The product arc swing mechanism 300 includes a product rotating seat 310 and a first rotation drive assembly. The first rotation drive assembly is disposed on the product support frame 100 and is drivenly connected to the product rotating seat 310. The product rotating seat 310 is provided with a product station, and the product station can move radially along the rotation circumference of the product rotating seat 310.

[0062] The polishing device includes a polishing support frame 500 and a polishing arc swing mechanism 600. The polishing arc swing mechanism 600 includes a polishing rotating seat 610 and a second rotation drive assembly. The second rotation drive assembly is disposed on the polishing support frame 500 and is drivenly connected to the polishing rotating seat 610. The polishing rotating seat 610 is provided with a polishing wheel mounting station, which can move radially along the rotation circumference of the polishing rotating seat 610.

[0063] The polishing wheel installation station is set directly opposite the product station. The polishing equipment also includes a translation drive mechanism 200, which drives and connects to the product arc swing mechanism 300 or the polishing arc swing mechanism 600.

[0064] When using the aforementioned polishing equipment, the product motion device includes a product arc swing mechanism 300, and the polishing device includes a polishing arc swing mechanism 600. The product rotating seat 310 in the product arc swing mechanism 300 has a product station. The product station can move radially along the rotation circumference of the product rotating seat 310, allowing the product station to be radially adjusted to an eccentric position on the product rotating seat 310. That is, the eccentric distance of the product station is adjustable. The first rotation drive assembly is driven by the product rotating seat 310, meaning the first rotation drive assembly can drive the product rotating seat 310 to rotate and can also drive the product station. The product to be polished undergoes an arc-shaped motion along the first direction. Through the translational motion of the composite translation drive mechanism 200 and the arc-shaped motion of the product arc-shaped mechanism 300, a single R-shaped bridge surface of a specified radius can be machined onto the product. The polishing rotary seat 610 in the polishing arc-shaped mechanism 600 is equipped with a polishing wheel mounting station. This station can move radially along the circumference of the polishing rotary seat 610, allowing it to be adjusted radially to an eccentric position. In other words, the eccentric distance of the polishing wheel mounting station is adjustable. The second rotary drive assembly is driven by the polishing rotary seat 610. That is, the second rotary drive assembly can drive the polishing rotary seat 610 to rotate, and can drive the polishing wheel assembly 800 on the polishing wheel mounting station to make an arc swing motion along the second direction. Through the translational motion of the composite translational drive mechanism 200, the arc swing motion of the product arc swing mechanism 300, and the arc swing motion of the polishing arc swing mechanism 600, a double-R bridge surface of a specified radius can be processed on the product. Therefore, the polishing processing equipment provided by this invention can meet the processing requirements of two different polishing profiles: single-R bridge surfaces and double-R bridge surfaces, improving the equipment's versatility. Furthermore, this application, through the product arc swing mechanism, the polishing arc swing mechanism, and... The coordination of the translation drive mechanism makes the processing path simpler, and the processing efficiency is higher and the cost is lower compared to a five-axis CNC machine tool. In addition, since the product station can move radially along the rotation circumference of the product rotary seat 310 and the polishing wheel mounting station can move radially along the rotation circumference of the polishing rotary seat 610, the eccentricity distance of the product station on the product rotary seat 310 and the eccentricity distance of the polishing wheel mounting station on the polishing rotary seat 610 can be adjusted. This allows the polishing processing equipment provided by the present invention to process double-R bridge surface products with different arc radii, thereby improving the versatility of the equipment.

[0065] It should be noted that the radial direction of the product rotating seat 310 mentioned later refers to the direction that passes through the center point of the rotating shaft of the product rotating seat 310 and is perpendicular to the center line of the rotating shaft of the product rotating seat 310, and the radial direction of the polishing rotating seat 610 refers to the direction that passes through the center point of the rotating shaft of the polishing rotating seat 610 and is perpendicular to the center line of the rotating shaft of the polishing rotating seat 610.

[0066] See Figure 2and Figure 3 In one embodiment of the present invention, the polishing arc pendulum mechanism 600 further includes a polishing eccentric seat 710 and a polishing eccentric drive assembly. The polishing eccentric drive assembly is disposed on the polishing rotary seat 610. The polishing eccentric seat 710 is radially movably disposed on the polishing rotary seat 610 and drivenly connected to the polishing eccentric drive assembly. The polishing eccentric seat 710 is provided with a polishing wheel mounting station. That is, by adding the polishing eccentric seat 710 and the polishing eccentric drive assembly, the eccentric distance between the polishing wheel mounting station and the center point of the rotating shaft of the polishing eccentric seat 710 can be automatically and adjustable. Therefore, when it is necessary to switch to polishing single-R or double-R bridge surface products with different radii, the position of the polishing eccentric seat 710 can be adjusted by controlling the polishing eccentric drive assembly. It should be noted that the polishing wheel body 820 installed on the polishing wheel mounting station is a contour polishing wheel. Specifically, when the product needs to obtain a convex arc surface, the polishing surface of the polishing wheel body 820 can be set as a concave arc surface to match it; when the product needs to obtain a concave arc surface, the polishing surface of the polishing wheel body 820 can be set as a convex arc surface to match it, so that the polishing wheel body 820 can be adapted to the product contour requirements.

[0067] In one embodiment of the present invention, the polishing eccentric drive assembly includes a polishing eccentric lead screw 720 and a polishing eccentric drive component 730. The polishing eccentric lead screw 720 is rotatably mounted on the polishing rotary seat 610 and extends radially along the polishing rotary seat 610. The polishing eccentric seat 610 has a first threaded hole for threaded connection with the polishing eccentric lead screw 720. The polishing eccentric drive component 730 is mounted on the polishing rotary seat 610 and drivenly connected to the polishing eccentric lead screw 720. That is, the position of the polishing wheel mounting station can be adjusted by moving the polishing eccentric seat 710 on the polishing eccentric lead screw 720. By using a rotary drive component plus lead screw structure to drive the polishing eccentric seat 710, high position adjustment accuracy and strong load-bearing capacity can be ensured. Specifically, the polishing eccentric drive component 730 may include, but is not limited to, a rotary motor. Of course, the present invention is not limited to this; the polishing eccentric seat 710 can also be driven by other suitable lifting mechanisms.

[0068] In one embodiment of the present invention, the polishing rotary seat 610 is further provided with a polishing eccentric guide rod 740 extending in the same direction as the polishing eccentric lead screw 720, and the polishing eccentric seat 710 is also provided with a first guide hole for the polishing eccentric guide rod 740 to pass through. By adding the polishing eccentric guide rod 740 and the second guide hole, the position adjustment of the polishing eccentric seat 710 can be guided, and the stability of the position adjustment can be further ensured. Specifically, each of the second guide holes is provided with a bushing that matches the polishing eccentric guide rod 740. The number of polishing eccentric guide rods 740 and the number of second guide holes are both at least two. At least two polishing eccentric guide rods 740 are arranged sequentially and at intervals around the polishing eccentric lead screw 720. At least two second guide holes are provided for at least two polishing eccentric guide rods 740 to pass through one-to-one. Preferably, the number of polishing eccentric guide rods 740 and the number of second guide holes are both four.

[0069] In one embodiment of the present invention, the polishing rotary seat 610 and the polishing support frame 500 are connected by a first bearing portion 614. The addition of the first bearing portion 614 can ensure the stability of the rotatable installation of the polishing rotary seat 610. Of course, the present invention is not limited to this. The polishing rotary seat 610 can also be mounted on the polishing support frame 500 using a rotating structure with a bushing and a shaft. At the same time, a first through hole 615 is provided on the first bearing portion 614. The first through hole 615 extends radially from the first bearing portion 614 and is positioned directly opposite the output shaft of the polishing eccentric drive assembly. Specifically, the first through hole 615 can be positioned directly opposite the polishing eccentric lead screw 720 in the polishing eccentric drive assembly. The polishing wheel shaft 810 on the polishing wheel mounting station passes through the first through hole 615. The addition of the first through hole 615 allows one end of the polishing wheel shaft 810, on which the polishing wheel body 820 is mounted, to extend out for processing the product to be polished. On the other hand, it can also serve as a guide. It should be noted that the first bearing part 614 can be a non-standard part with cylindrical balls machined into the inner ring of the bearing on the polished rotating seat 610, or a standard bearing part can be used.

[0070] Specifically, the polishing wheel assembly 800 includes a polishing wheel shaft 810 and a polishing wheel drive motor and a polishing wheel body 820 respectively disposed at both ends of the polishing wheel shaft 810. The polishing wheel drive motor is disposed on the polishing eccentric seat 710 and can drive the polishing wheel shaft 810 to drive the polishing wheel body 820 to rotate.

[0071] In one embodiment of the present invention, the polishing rotary seat 610 includes a first base plate 611 and a first top plate 612 arranged sequentially from bottom to top, and a first connecting member 613 connecting the first base plate 611 and the first top plate 612. The first connecting member 613 is rotatably mounted on the polishing support frame 500. Specifically, the first connecting member 613 may be provided with a first bearing portion 614. The polishing eccentric drive assembly includes a polishing eccentric screw 720 and a polishing eccentric drive member 730. The two ends of the polishing eccentric screw 720 are respectively rotatably mounted on the first base plate 611 and the first top plate 612. The polishing eccentric seat 710 is provided with a first threaded hole that is threadedly connected to the polishing eccentric screw 720. The polishing eccentric drive member 730 is drivenly connected to the polishing eccentric screw 720. By setting the polishing rotating seat 610 as described above, on the one hand, the structural strength is guaranteed, and on the other hand, the eccentric adjustment drive structure can be set on the first base plate 611 and the first top plate 612, while the rotation drive structure is set on the first connecting member 613. The two drive structures are set separately, and the layout is simple and reasonable.

[0072] Specifically, a polishing eccentric drive component 730 is provided on the first top plate 612, which is driven to the upper end of the polishing eccentric lead screw 720. Of course, it is also possible for the polishing eccentric drive component 730 to be provided on the first bottom plate 611 and driven to the lower end of the polishing eccentric lead screw 720. At the same time, the upper and lower ends of the polishing eccentric guide rod 740 are respectively connected to the first bottom plate 611 and the first top plate 612, and the first bottom plate 611, the first top plate 612, the first connecting component 613 and the polishing eccentric guide rod 740 can form a rigid structure.

[0073] In one embodiment of the present invention, a first transmission gear portion 711 connected to a first bearing portion 614 is provided on the outer side of the polishing eccentric seat 710. The center line of the circumference of the first transmission gear portion 711 is collinear with the center line of the circumference of the first bearing portion 614. The second rotary drive assembly includes a first rotary drive member 620 and a first drive gear 621. The first rotary drive member 620 is disposed on the polishing support frame 500, and the first drive gear 621 is disposed at the output end of the first rotary drive member 620 and meshes with the first transmission gear portion 711. By adding a first transmission gear portion 711 coaxially disposed with the first bearing portion 614 to the polishing eccentric seat 710, the polishing eccentric seat 710 can be driven to rotate by gear transmission, thereby facilitating the arrangement of the second rotary drive assembly.

[0074] Specifically, the first transmission gear 711 may have teeth only on the side where the second rotary drive assembly is located, and the first transmission gear 711 may be a partial arc segment, not requiring teeth to be provided around the entire circle, as long as it can achieve arc-shaped oscillation. Furthermore, the reciprocating motion of the oscillation can be achieved by controlling the forward and reverse rotation of the first rotary drive 620. More specifically, the polishing support frame 500 is provided with a first support plate 622 for mounting the first rotary drive 620, which includes, but is not limited to, a motor.

[0075] In one embodiment of the present invention, the polishing support frame 500 includes an adjusting main seat 530, and a polishing arc swing mechanism 600 is disposed on the adjusting main seat 530. The polishing device also includes a pressure adjusting assembly, which includes a telescopic drive member 540, a distance adjuster 550, and a pressure sensor 560. The telescopic end of the telescopic drive member 540 is driven to the adjusting main seat 530. The distance adjuster 550 is disposed in the moving direction of the adjusting main seat 530, and the moving direction of the adjusting main seat 530 is the pressure action direction of the polishing wheel 820. The pressure sensor 560 is disposed at one end of the adjusting main seat 530 facing the distance adjuster 550. The distance adjuster 550 can adjust the distance between its own end and the pressure sensor 560. Alternatively, the pressure sensor 560 can be disposed at one end of the distance adjuster 550 facing the adjusting main seat 530. In this case, the distance adjuster 550 can adjust the distance between the pressure sensor 560 and the main seat 530. During the polishing process, the pressure sensor 560 can detect the downward pressure during polishing. If the downward pressure exceeds the set working range, the downward pressure can be adjusted by controlling the telescopic drive component 540. This allows for feedback adjustment of the downward pressure during polishing, ensuring a stable output of the downward pressure during the polishing process.

[0076] Specifically, the polishing support frame 500 also includes an adjusting guide rod 520, an adjusting main body seat 530 which is vertically mounted on the adjusting guide rod 520, a distance adjuster 550 located on the lower side of the adjusting main body seat 530, preferably, a pressure sensor 560 located at the end of the distance adjuster 550 facing the adjusting main body seat 530, the pressure sensor 560 being able to abut against the adjusting main body seat 530, and a telescopic drive member 540 located on the lower side of the adjusting main body seat 530 with its telescopic end being drivenly connected to the adjusting main body seat 530.

[0077] In one embodiment of the present invention, the polishing support frame 500 further includes an outer support frame 510, which forms a supporting cavity. An adjusting guide rod 520 is erected in the supporting cavity, and a distance adjuster 550 is vertically mounted on the lower end plate of the outer support frame 510. A telescopic drive member 540 is located on the inner side of the lower end plate of the outer support frame 510. The addition of the outer support frame 510 facilitates the assembly of the adjusting guide rod 520, the distance adjuster 550, and the telescopic drive member 540. Furthermore, the lower end of the distance adjuster 550 extending from the supporting cavity can be provided with a supporting foot. The rod portion of the distance adjuster 550, which passes through the lower end plate of the outer support frame 510, has an external thread and is threadedly connected to an internal threaded hole on the lower end plate. This allows for manual adjustment of the distance between the pressure sensor 560 at the upper end of the distance adjuster 550 and the adjusting body seat 530, ensuring that downward pressure can be detected.

[0078] See Figures 4 to 6 In one embodiment of the present invention, the product arc swing mechanism 300 further includes a product eccentric seat 410 and a product eccentric drive assembly. The product eccentric drive assembly is disposed on the product rotating seat 310. The product eccentric seat 410 is radially movably disposed on the product rotating seat 310 and drivenly connected to the product eccentric drive assembly. The product eccentric seat 410 is provided with a product station. That is, by adding the product eccentric seat 410 and the product eccentric drive assembly, the eccentric distance between the product station and the center point of the rotating shaft of the product eccentric seat 410 can be automatically and adjustable. Therefore, when it is necessary to switch to polishing double-R bridge surface products with different radii, the position of the product eccentric seat 410 can be adjusted by controlling the product eccentric drive assembly.

[0079] In one embodiment of the present invention, the product eccentric drive assembly includes a product eccentric screw 420 and a product eccentric drive member 430. The product eccentric screw 420 is rotatably mounted on the product rotating seat 310 and extends radially along the product rotating seat 310. The product eccentric seat 410 has a second threaded hole for threaded connection with the product eccentric screw 420. The product eccentric drive member 430 is mounted on the product rotating seat 310 and can drive the product eccentric screw 420 to rotate. That is, the position of the product station can be adjusted by moving the product eccentric seat 410 on the product eccentric screw 420. By using a rotary drive member plus screw structure to drive the product eccentric seat 410, high position adjustment accuracy and strong load-bearing capacity can be ensured. Specifically, the product eccentric drive member 430 may include, but is not limited to, a rotary motor. Of course, the present invention is not limited to this; the product eccentric seat 410 can also be driven by other suitable lifting mechanisms.

[0080] In one embodiment of the present invention, the product swing mechanism 300 is further provided with a product eccentric guide rod 440 extending in the same direction as the product eccentric lead screw 420, and the product eccentric seat 410 is further provided with a second guide hole for the product eccentric guide rod 440 to pass through. The addition of the product eccentric guide rod 440 and the second guide hole can guide the position adjustment of the product eccentric seat 410 and further ensure the stability of the position adjustment. Specifically, each of the second guide holes is provided with a bushing matching the product eccentric guide rod 440. There are at least two product eccentric guide rods 440 and at least two second guide holes. At least two product eccentric guide rods 440 are arranged sequentially and at intervals around the product eccentric lead screw 420. At least two second guide holes allow at least two product eccentric guide rods 440 to pass through one-to-one. Preferably, there are four product eccentric guide rods 440 and four second guide holes.

[0081] In one embodiment of the present invention, the product rotating seat 310 includes a second base plate 311 and a second top plate 312 arranged sequentially from bottom to top, and a second connecting member 313 connecting the second base plate 311 and the second top plate 312. The second connecting member 313 is rotatably mounted on the product support frame 100. The product eccentric screw 420 is rotatably mounted, and its two ends are respectively rotatably mounted on the second base plate 311 and the second top plate 312. With the product rotating seat 310 arranged as described above, structural strength is ensured, and the eccentric adjustment drive structure is located on the second base plate 311 and the second top plate 312, while the rotation drive structure is located on the second connecting member 313. The two drive structures are separately arranged, resulting in a simple and reasonable layout.

[0082] Specifically, the second top plate 312 is provided with a product eccentric drive component 430, which is driven to the upper end of the product eccentric screw 420. Of course, it is also possible for the product eccentric drive component 430 to be provided on the second bottom plate 311 and driven to the lower end of the product eccentric screw 420. At the same time, the upper and lower ends of the product eccentric guide rod 440 are respectively connected to the second bottom plate 311 and the second top plate 312, and the second bottom plate 311, the second top plate 312, the second connecting component 313 and the product eccentric guide rod 440 can form a rigid structure.

[0083] In one embodiment of the present invention, the product rotating seat 310 is provided with a second bearing portion 314. Specifically, the second connecting member 313 of the product rotating seat 310 is provided with a second bearing portion 314. The product rotating seat 310 is rotatably mounted on the product support frame 100 through the second bearing portion 314. By adding the second bearing portion 314, the stability of the rotatable installation of the product rotating seat 310 can be ensured. Of course, the present invention is not limited to this. The second connecting member 313 can also be provided on the product support frame 100 with a rotating structure of bushing and shaft cooperation. Meanwhile, a second through hole 315 is provided on the second bearing portion 314. The second through hole 315 extends radially on the second bearing portion 314 and is arranged parallel to the product eccentric screw 420. The product eccentric seat 410 includes an eccentric drive portion 411 and a product clamping portion 412 connected to each other. The eccentric drive portion 411 is drivenly connected to the product eccentric drive assembly. Specifically, the eccentric drive portion 411 is provided with a second threaded hole, that is, the eccentric drive portion 411 and the product eccentric screw 420 are connected. A threaded connection is used, and the product clamping part 412 is located between the second base plate 311 and the second top plate 312. The product clamping part 412 passes through the second through hole 315 and is located on the side of the product rotating seat 310 opposite to the eccentric drive part 411. Specifically, the product clamping part 412 can be located on the side of the second connecting member 313 opposite to the eccentric drive part 411, and the product clamping part 412 is connected to the eccentric drive part 411 through the second through hole 315. A product fixing seat forming a product station is connected to the product clamping part 412. This allows the product clamping part 412 and the eccentric drive part 411 to be located on opposite sides of the second connecting member 313, and the product clamping part 412 is unobstructed, facilitating the assembly and disassembly of the product fixing seat and the smooth polishing of the product. Specifically, the product clamping part 412 has a protruding structure that is detachably connected to the eccentric drive part 411 through the second through hole 315. It should be noted that the second bearing part 314 can be a non-standard part machined on the second connecting member 313 to have cylindrical balls in the inner ring of the bearing, or a standard bearing part can be used.

[0084] In one embodiment of the present invention, a second transmission gear portion 316 and a second bearing portion 314 protrude sequentially from the inside to the outside on the side of the second connecting member 313 opposite to the eccentric drive portion 411. The second transmission gear portion 316 and the second bearing portion 314 are coaxially arranged. The first rotary drive assembly includes a second rotary drive member 320 and a second drive gear 321. The second rotary drive member 320 is disposed on the product support frame 100 and located on one side of the second connecting member 313. The output end of the second rotary drive member 320 is provided with a second drive gear 321, which meshes with the second transmission gear portion 316. By adding a second transmission gear portion 316 stacked on the second connecting member 313 and arranged in a layered manner with the second bearing portion 314, the product rotating seat 310 can be driven to rotate by gear transmission, thereby facilitating the arrangement of the first rotary drive assembly.

[0085] Specifically, the outer diameter of the second transmission gear portion 316 is larger than the outer diameter of the second bearing portion 314, so that an axial stop end face is formed between the second transmission gear portion 316 and the second bearing portion 314, which facilitates the axial positioning and installation of the product rotating seat 310. Simultaneously, the second transmission gear portion 316 can have teeth formed only on the side where the second rotary drive member 320 is located, without needing teeth on the entire circumference; it only needs to achieve arc-shaped oscillation. Furthermore, the reciprocating motion of the oscillation can be achieved by controlling the forward and reverse rotation of the second rotary drive member 320. More specifically, the product support frame 100 is provided with a second support plate 322 for mounting the second rotary drive member 320, which includes, but is not limited to, a motor.

[0086] In one embodiment of the present invention, the center line of the rotation axis of the polishing rotary seat 610 is set perpendicular to the center line of the rotation axis of the product rotary seat 310, thereby enabling the product to be processed into a double-R bridge surface product with orthogonal intersection.

[0087] See Figure 4 , Figure 5 and Figure 7 In one embodiment of the present invention, the translation drive mechanism 200 includes a translation drive assembly and a translation push seat 210. The translation drive assembly drives and connects to the translation push seat 210. The translation push seat 210 includes a translation base plate 211 and a translation upright plate 212. The translation upright plate 212 is erected on the translation base plate 211, and a product arc swing mechanism 300 or a polishing arc swing mechanism 600 is mounted on the translation upright plate 212. By setting the translation push seat 210 as a combination of the translation base plate 211 and the translation upright plate 212, the translation installation structure and the rotation structure can be arranged sequentially along the height direction, and the translation upright plate 212 can provide a larger installation space.

[0088] Furthermore, the translation base plate 211 is movably mounted on the product support frame 100 or the polishing support frame 500, the translation upright plate 212 can be installed on the corresponding arc swing mechanism, and the translation drive assembly is mounted on the corresponding support frame and drivenly connected to the translation base plate 211 so as to drive the translation base plate 211 to reciprocate.

[0089] Furthermore, when the translation drive mechanism 200 is mounted on the product support frame 100 and can be installed on the product swing mechanism 300, the translation upright plate 212 is provided with a first mounting hole 213 for the second bearing part 314 to be rotatably mounted. The axial stop end face formed between the second transmission gear part 316 and the second bearing part 314 can be fitted against the side of the translation upright plate 212 away from the product fixing seat. The side of the translation upright plate 212 facing the product fixing seat is provided with a cover plate 214 to cover the second bearing part 314.

[0090] In one embodiment of the present invention, the translation drive assembly includes a translation drive component 220 disposed on the product support frame 100 or the polishing support frame 500, and a translation screw 230 driving the translation drive component 220 and the translation base plate 211. That is, the translation drive assembly adopts a ball screw pair drive method, which can ensure that the translation push seat 210 has high position adjustment accuracy and strong load-bearing capacity. Specifically, the translation drive component 220 includes, but is not limited to, a motor. Furthermore, a translation guide assembly can also be disposed on the corresponding support frame, and the translation base plate 211 can be movably mounted on the corresponding support frame through the translation guide assembly. Further, the translation guide assembly includes translation guide rods 240 disposed on opposite sides of the translation screw 230, and the translation base plate 211 can be movably mounted through the translation guide rods 240. The addition of the translation guide assembly can guide the position adjustment of the translation push seat 210 and further ensure the stability of the position adjustment.

[0091] Please see again Figure 4 and Figure 5 In one embodiment of the present invention, the product motion device further includes a product rotation drive 450 disposed on the product arc swing mechanism 300, and a product station is provided at the end of the output shaft of the product rotation drive 450. That is, the product to be polished can be placed at the end of the output shaft of the product rotation drive 450, so that the product to be polished can rotate under the drive of the product rotation drive 450. This allows polishing of standard spherical surfaces, non-standard spherical surfaces, and skirted spherical surfaces to be performed through the rotation of the composite product rotation drive 450 and the rotation of the product arc swing mechanism 300. At this time, the translation drive mechanism 200 can stop driving, thereby further improving the versatility of the equipment. Specifically, the main body of the product rotation drive 450 can be located on the lower side of the product clamping part 412 of the product eccentric seat 410, and the output shaft of the product rotation drive 450 is arranged upward. A product fixing seat forming an installation position can be connected to the output shaft. The center line of the output shaft can be arranged parallel to the product eccentric lead screw 420 so that the product position is in the radial direction of the product arc swing mechanism 300. The product rotation drive 450 includes, but is not limited to, a motor.

[0092] In one embodiment of the present invention, the polishing device further includes a polishing wheel assembly 800 disposed at the polishing wheel mounting station. The two ends of the polishing wheel shaft 810 of the polishing wheel assembly 800 extend from opposite sides of the polishing support frame 500, and both ends of the polishing wheel shaft 810 are provided with polishing wheel bodies 820. There are two product motion devices, each corresponding to one of the polishing wheel bodies 820 at each end of the polishing wheel shaft 810. On the one hand, providing polishing wheel bodies 820 at both ends of the polishing wheel shaft 810 ensures stability during the polishing process; on the other hand, it enables dual-station polishing, thereby improving polishing efficiency.
