Description

Technical Field

[0001] The present application relates to the field of glass polishing, and in particular to a plane polishing device for round glass. Background Art

[0002] After the glass is processed, its surface needs to be polished to improve the gloss and flatness of the glass surface.

[0003] At present, the polishing operation of round glass is to place the round glass in a fixture, and then the polishing disc contacts the glass surface and rotates to achieve the polishing operation of the glass surface. Because the polishing disc will completely cover the surface of the glass, polishing liquid will be added to the glass surface before polishing, and then polishing will be performed. If the polishing time is long, the polishing disc needs to rise and then add polishing liquid to the glass, that is, polishing liquid cannot be added between the glass and the polishing disc during the polishing process, which affects the polishing efficiency of the glass. Summary of the invention

[0006] By adopting the above technical scheme, the circular glass to be processed is placed on the fixture, and then the polishing disc descends to contact the surface of all the circular glasses, and then the ring plate rotates, and the inner gear ring drives all the driving gears to rotate, that is, the fixture drives all the circular glasses to rotate, and at the same time the polishing disc rotates, so that the glass surface can be polished; the rotation direction of the polishing disc is opposite to the rotation direction of the glass, which further improves the polishing effect; during the polishing process, the spray pipe intermittently sprays polishing liquid upward, and the polishing liquid will adhere to the lower surface of the polishing disc, and then when the polishing disc rotates onto the glass, and in coordination with the rotation of the glass, the polishing liquid will be evenly distributed, that is, during the polishing process, the polishing liquid can be intermittently sprayed onto the polishing disc to ensure the polishing effect, and the polishing liquid can be continuously replenished during the polishing process, which helps to improve the polishing efficiency.

[0007] Preferably, a screw slide is arranged on the machine body in the vertical direction, a mounting box is arranged on the slide of the screw slide, a driving motor is arranged in the mounting box, an output shaft of the driving motor extends out of the mounting box, and the polishing disc is fixedly connected to the output shaft of the driving motor.

[0008] By adopting the above technical solution, the screw slide can be used to drive the lifting movement of the installation box, thereby realizing the lifting movement of the polishing disc, and the driving motor can be operated to realize the rotation of the polishing disc.

[0009] Preferably, an outer gear ring is formed on the outer side of the ring plate, a linkage gear is rotatably connected in the body, the linkage gear is meshed with the outer gear ring, and a driving member for driving the linkage gear to rotate is arranged in the body.

[0010] By adopting the above technical solution, the driving member drives the linkage gear to rotate, and the linkage gear drives the ring plate to rotate through the outer gear ring, and the ring plate can drive all the fixtures to rotate.

[0011] Preferably, a first pulley is coaxially fixed on the output shaft of the driving motor, a second pulley is rotatably connected in the installation box, belts are wound around the first pulley and the second pulley, the driving member is configured as a driving rod, the driving rod is rotatably connected to the installation box, and the second pulley is coaxially fixed on the driving rod, a square rod portion is formed on the driving rod, a square groove is opened in the middle position of the linkage gear, and the square rod portion of the driving rod is plugged into and slidingly matched with the square groove.

[0012] By adopting the above technical solution, the driving motor runs, driving the polishing disc to rotate, and at the same time the driving motor drives the first pulley to rotate, the first pulley drives the second pulley to rotate through the belt, and the second pulley drives the driving rod to rotate. Due to the insertion of the square rod and the square groove, the driving rod and the linkage gear rotate coaxially, that is, the driving rod will drive the linkage gear to rotate.

[0013] Preferably, the machine body is provided with a transfer tube in the middle of all the jigs, all the circumferential arrays of the spray tubes are on the circumferential side of the transfer tube, and the spray tube is connected to the transfer tube, and a liquid inlet tube is provided in the machine body, and the liquid inlet tube is connected to the transfer tube, and the intermittent mechanism includes a sealing plate and a return spring, a flaring portion is formed on the liquid inlet tube, the sealing plate slides in the flaring portion, and the return spring is arranged in the flaring portion, and one end of the return spring is connected to the sealing plate, and the other end of the return spring is connected to the inner wall of the flaring portion; a toggle sub-plate is arranged on the sealing plate, and the toggle sub-plate passes through the flaring portion, and a toggle wheel is fixedly connected to the lower end of the driving rod, and a toggle mother plate is arranged at the edge of the toggle wheel; the driving rod drives the toggle wheel to rotate, the toggle mother plate toggle the toggle sub-plate, and the toggle sub-plate drives the sealing plate to slide, and when the toggle mother plate and the toggle sub-plate are separated, the return spring acts to reset the sealing plate.

[0014] By adopting the above technical solution, the screw slide drives the installation box to descend, and when the polishing disk and the circular glass abut, the driving rod also stops descending synchronously. At this time, the toggle mother plate moves to the same horizontal plane as the toggle sub-plate. When the driving rod rotates, the toggle mother plate can drive the toggle sub-plate to move, so that the sealing plate can slide in the flared part. After sliding, the polishing liquid can flow and spray out from the spray pipe. When the toggle mother plate and the toggle sub-plate are separated, the sealing plate is reset under the action of the reset spring to block the liquid inlet pipe. During the rotation of the toggle wheel, the sealing plate moves back and forth, thereby realizing intermittent liquid spraying.

[0015] Preferably, the liquid spray pipe is provided with a plurality of branch pipes, the branch pipes are inclined and inclined in the direction close to the jig; a supporting plate is provided in the body, a hose portion is formed on the liquid inlet pipe, the hose portion is overlapped and fixed on the supporting plate, a vertical plate is formed on the supporting plate, an inclined sliding groove is formed on the vertical plate, and the sliding groove is inclined downward along the flow direction of the liquid in the hose portion, the vertical plate is located in the sliding groove and is slidably provided with a sliding rod, and an extrusion wheel is coaxially fixed on the sliding rod; before the polishing disc abuts against the glass, when the sliding rod slides in the sliding groove, the extrusion wheel squeezes the hose portion, and at this time the polishing liquid will be sprayed out from the branch pipe and fall onto the glass surface.

[0016] By adopting the above technical solution, polishing liquid needs to be added in advance before polishing. If the polishing disc directly contacts the glass and then the polishing liquid is sprayed, there is no polishing liquid between the polishing disc and the glass during the initial rotation, which affects the polishing effect. Therefore, before the polishing disc and the glass contact, the sliding rod slides in the sliding groove and drives the extrusion wheel to move. Since the sliding groove is inclined, the extrusion wheel will squeeze the hose part, so that the polishing liquid is sprayed out from the branch pipe. Since the branch pipe is inclined, the trajectory of the polishing liquid after spraying is parabolic and finally falls on the surface of the glass. During subsequent polishing, the self-rotation of the glass cooperates with the rotation of the polishing disc, so that the polishing liquid can quickly cover the surface of the glass. After that, the sliding rod is reset, the polishing disc contacts the glass, the toggle wheel rotates, and the sealing plate slides back and forth to replenish the subsequent polishing liquid.

[0017] Preferably, the vertical plate is hinged with a rotating plate by a torsion spring, and in the initial state, the rotating plate is tilted upward, and the sliding groove is provided on the rotating plate; the driving rod is rotatably connected with a hollow plate, and the hollow plate is sleeved on the peripheral side of the supporting plate to form a sliding fit, and a first waist-shaped groove is provided on the hollow plate in the horizontal direction, and a vertical second waist-shaped groove is provided on one end of the hollow plate located at the first waist-shaped groove, and in the initial state, the sliding rod is located in the first waist-shaped groove; when the hollow plate descends, the rotating plate rotates, and the sliding rod slides along the sliding groove When the sliding rod moves to the second waist-shaped groove, the torsion spring acts, the rotating plate is reset, and the sliding rod enters the second waist-shaped groove; a third waist-shaped groove is also provided on the hollow plate, and the third waist-shaped groove is inclined. One end of the third waist-shaped groove is connected with the end of the first waist-shaped groove away from the second waist-shaped groove to form a connecting port, and the other end of the third waist-shaped groove is connected with the second waist-shaped groove; when the hollow plate rises and resets, the sliding rod moves in the second waist-shaped groove to the connecting point with the third waist-shaped groove, and the sliding rod enters the third waist-shaped groove due to gravity and finally resets to the first waist-shaped groove.

[0018] By adopting the above technical scheme, the installation box descends, and the hollow plate is driven to descend by the driving rod. The hollow plate descends relative to the supporting plate, and due to the cooperation between the hollow plate and the supporting plate, the hollow plate will not rotate with the driving rod, and the first waist-shaped groove limits the sliding rod in the vertical direction, thereby driving the sliding rod to move downward, thereby driving the rotating plate to rotate. When the rotating plate is tilted, the sliding rod will slide along the sliding groove until the sliding rod moves into the second waist-shaped groove, and the torsion spring drives the rotating plate to return to its initial inclined state; when the rotating plate is tilted downward and the sliding rod slides along the sliding groove, the extrusion wheel can squeeze the hose part to realize the spraying of the branch pipe; after the polishing operation is completed, the hollow plate rises until the sliding rod enters the third waist-shaped groove. At this time, the inclination direction of the third waist-shaped groove is consistent with that of the sliding groove. Due to the action of gravity, the sliding rod slides downward along the third waist-shaped groove and returns to the first waist-shaped groove.

[0019] Preferably, the hollow plate is located in the second waist-shaped groove and is hinged with a baffle through a torsion spring. The baffle is arranged at an angle and can only be rotated upward. The inclination direction of the baffle is consistent with the inclination direction of the third waist-shaped groove. Before the hollow plate rises and resets, the baffle abuts against the sliding rod to limit the sliding rod, and then the hollow plate continues to rise until it is reset. At this time, the rotating plate rotates upward and the sliding groove is consistent with the inclination direction of the third waist-shaped groove. Then the sliding rod slides along the sliding groove and the third waist-shaped groove to the first waist-shaped groove due to gravity, and then the torsion spring drives the rotating plate to reset. At the same time, the sliding rod slides in the first waist-shaped groove and disengages from the connecting port.

[0020] By adopting the above-mentioned technical scheme, when the hollow plate rises and resets, the inclination direction of the third waist-shaped groove is exactly consistent with the sliding groove. At this time, the sliding rod will slide along the third waist-shaped groove to the connecting port, but when the hollow plate descends, there is a situation where the sliding rod enters the third waist-shaped groove, affecting the normal movement of the sliding rod; therefore, in the present application, before the hollow plate rises and resets, the baffle plate abuts against the sliding rod, and then the hollow plate continues to rise until it is reset. At this time, the sliding rod maintains abutment with the baffle plate, and the rotating plate rotates upward. At this time, the inclination direction of the third waist-shaped groove is consistent with the sliding groove, the sliding rod slides along the third waist-shaped groove to the connecting port, and then the rotating plate is reset under the action of the torsion spring, and the sliding rod moves a certain distance in the first waist-shaped groove and disengages from the connecting port to prevent the sliding rod from being unable to slide down when the hollow plate descends subsequently.

[0021] Preferably, a lifting groove is provided on the bottom wall of the hollow plate located at the first waist-shaped groove, and a wedge-shaped block is provided in the lifting groove for lifting and sliding of the hollow plate. A compression spring is provided in the lifting groove of the hollow plate, one end of the compression spring is connected to the bottom of the wedge-shaped block, and the other end of the compression spring is connected to the bottom wall of the lifting groove; a wedge-shaped surface is formed on the side of the wedge-shaped block close to the connecting port, and a blocking surface is formed on the side of the wedge-shaped block away from the connecting port.

[0022] By adopting the above technical solution, when the sliding rod slides from the third waist-shaped groove into the connecting port, and then the rotating plate is reset to drive the sliding rod to slide in the first waist-shaped groove, the sliding rod contacts the wedge surface of the wedge block, so that the wedge block slides into the lifting groove to avoid the sliding of the sliding rod. When the sliding rod is separated from the wedge block, the compression spring acts and the wedge block extends out of the lifting groove. At this time, the blocking surface can limit the direction of the sliding of the sliding rod; because the initial state of the rotating plate is inclined upward, when the hollow plate descends, if there is no wedge block to block the sliding rod, the sliding rod may slide toward the connecting port, resulting in the rotating plate being unable to rotate downward.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. A liquid spray pipe is arranged between adjacent jigs. During the polishing process, the liquid spray pipe sprays liquid upward, and the polishing liquid is sprayed onto the polishing disc. During the rotation of the polishing disc, the polishing liquid can be located between the glass and the polishing disc to ensure the polishing effect; 2. The driving motor drives the polishing disc to rotate. At the same time, the driving motor realizes the rotation of the driving rod through the first pulley, the second pulley and the belt. The driving rod and the linkage gear rotate coaxially. The linkage gear drives the ring plate to rotate through the outer gear ring. The ring plate drives all the driving gears to rotate through the inner gear ring, so as to realize the synchronous rotation of all the jigs. The rotation direction of the jig is opposite to that of the polishing disc, which helps to further improve the polishing effect. 3. Before the polishing disc descends and contacts the glass, the hollow plate drives the sliding rod to move, and the sliding rod drives the extrusion wheel to move. The extrusion wheel squeezes the hose part, so that the branch pipe sprays the polishing liquid outward. Because the branch pipe is inclined, the spraying trajectory of the polishing liquid is parabolic and falls on the glass, ensuring that there is polishing liquid between the two when the polishing disc rotates, preventing the polishing effect from being affected when there is no polishing liquid between the two when the polishing disc rotates at the beginning.

The polishing disc 3 rotates to achieve the polishing operation of the glass, and the spray pipe 4 can spray liquid onto the polishing disc 3. When the polishing disc 3 rotates the glass, the polishing liquid can be driven to the glass to ensure that during the polishing process, there is always polishing liquid between the polishing disc 3 and the glass, that is, during the polishing process, the polishing liquid can be continuously replenished, which helps to ensure the polishing efficiency of the glass.

The body 1 is located in the receiving groove 11 and is suspended with a mounting plate 5, and a ring plate 51 is rotatably connected to the mounting plate 5 through a plane bearing. An inner gear ring 511 is formed on the inner side of the ring plate 51, and the inner gear ring 511 meshes with all the driving gears 21. An outer gear ring 512 is also formed on the outer side of the ring plate 51. The body 1 is located in the receiving groove 11 and is also rotatably connected with a linkage gear 6, which meshes with the outer gear ring 512. A driving member for driving the linkage gear 6 to rotate is provided on the body 1.

[0031] The driving member drives the linkage gear 6 to rotate, and the linkage gear 6 drives the ring plate 51 to rotate through the outer ring gear 512, and the ring plate 51 drives all the driving gears 21 to rotate through the inner ring gear 511, thereby realizing the rotation of all the fixtures 2, and the rotation direction of the fixture 2 is opposite to the rotation direction of the polishing plate 3.

[0032] A screw slide 12 is installed on the body 1 in the vertical direction, and a mounting box 13 is fixedly installed on the slide of the screw slide 12. A drive motor 131 is installed in the mounting box 13. The output shaft of the drive motor 131 extends out of the mounting box 13, and the polishing disc 3 is fixedly connected to the output shaft of the drive motor 131.

[0033] A first pulley 14 is coaxially fixed on the output shaft of the driving motor 131, and a second pulley 15 is rotatably connected in the installation box 13. A belt 16 is sleeved on the first pulley 14 and the second pulley 15.

A square rod portion 71 is formed on the driving rod 7, and a square groove 61 is opened through the middle of the linkage gear 6, and the square rod of the driving rod 7 is plugged into and slidably matched with the square groove 61.

[0034] The driving motor 131 runs to drive the polishing disc 3 to rotate. At the same time, the driving motor 131 drives the first pulley 14 to rotate synchronously. The first pulley 14 drives the second pulley 15 to rotate through the belt 16, thereby realizing the rotation of the driving rod 7. The driving rod 7 drives the linkage gear 6 to rotate, thereby realizing the rotation of the linkage gear 6.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The machine body 1 is located in the middle of all the jigs 2 and is equipped with a transfer pipe 17. All the spray pipes 4 are arranged horizontally and are arranged on the circumference of the transfer pipe 17. The spray pipes 4 are connected to the transfer pipe 17. The machine body 1 is located in the receiving tank 11 and is equipped with a liquid inlet pipe 8. One end of the liquid inlet pipe 8 is connected to the transfer pipe 17, and the other end is connected to the external polishing liquid. An intermittent mechanism 9 is arranged in the machine body 1. The intermittent mechanism 9 includes a sealing plate 91 and a reset spring 92. A flared portion 81 is formed on the liquid inlet pipe 8. The flared portion 81 is in the shape of a rectangular block. The sealing plate 91 slides in the flared portion 81 to block and open the liquid inlet pipe 8. The sealing plate 91 is provided with a connecting hole for connecting with the liquid inlet pipe 8. The reset spring 92 is located in the flared portion 81. One end of the reset spring 92 is connected to the sealing plate 91, and the other end of the reset spring 92 is connected to the inner wall of the flared portion 81. The blocking plate 91 is integrally formed with a toggle sub-plate 911, which passes through the flared portion 81. A toggle wheel 72 is coaxially fixed to the lower end of the driving rod 7, and a toggle mother plate 721 is fixedly connected to the toggle wheel 72. When the driving rod 7 rotates, the toggle wheel 72 rotates accordingly, and the toggle mother plate 721 toggles the toggle sub-plate 911, and the toggle sub-plate 911 drives the blocking plate 91 to slide. When the toggle mother plate 721 is separated from the toggle sub-plate 911, the reset spring 92 acts to reset the blocking plate 91, that is, the blocking plate 91 moves back and forth to achieve intermittent liquid spraying.

[0036] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6, the liquid spraying pipe 4 is connected with a plurality of branch pipes 41, the branch pipes 41 are arranged obliquely in the vertical direction, and the branch pipes 41 are inclined in the direction close to the fixture 2. A support plate 10 is fixedly installed in the machine body 1, and a hose portion 82 is formed on the liquid inlet pipe 8, and the hose portion 82 has a larger diameter, and the hose portion 82 is fixed on the support plate 10; a vertical plate 101 is fixedly connected to the support plate 10, and a rotating plate 20 is hinged on the vertical plate 101 through a torsion spring, and in the initial state, the rotating plate 20 is arranged obliquely upward, and a sliding groove 201 is opened along the length direction of the rotating plate 20, and the rotating plate 20 is located in the sliding groove 201 and is slidably connected to a sliding rod 30, and an extrusion wheel 301 is coaxially fixed on the sliding rod 30. The middle part of the driving rod 7 is rotatably connected with a hollow plate 40, which surrounds the peripheral side of the supporting plate 10 and forms a sliding fit with the supporting plate 10. Due to the cooperation between the supporting plate 10 and the hollow plate 40, the hollow plate 40 does not rotate with the driving rod 7; a first waist-shaped groove 401 is opened on the hollow plate 40 in the horizontal direction, and a second waist-shaped groove 402 is opened on the hollow plate 40 in the vertical direction. The lower end of the second waist-shaped groove 402 is connected to the end of the first waist-shaped groove 401. In the initial state, the sliding rod 30 is located in the first waist-shaped groove 401.

[0037] When the driving rod 7 descends, the hollow plate 40 descends, and the hollow plate 40 drives the sliding rod 30 to move downward through the first waist groove 401, and at the same time drives the rotating plate 20 to rotate downward. When the rotating plate 20 rotates and is set to be tilted downward and overlapped on the supporting plate 10, when the hollow plate 40 descends, the sliding rod 30 will slide downward along the sliding groove 201, and the extrusion wheel 301 moves and squeezes the hose part 82. Under the extrusion effect, the polishing liquid will be sprayed out from the branch pipe 41. Because the branch pipe 41 is set at an angle, the trajectory of the polishing liquid is parabolic and sprinkled on the surface of the glass, which can ensure that the polishing disc 3 has polishing liquid when it is initially rotated, ensuring the polishing effect. After the sliding rod 30 enters the second waist groove 402, under the action of the torsion spring, the rotating plate 20 is reset, and the extrusion wheel 301 no longer squeezes the hose part 82 to prevent affecting the subsequent transmission of the polishing liquid.

[0038] A third waist-shaped groove 403 is also provided on the hollow plate 40 , and the third waist-shaped groove 403 is inclined. One end of the third waist-shaped groove 403 is connected to one end of the first waist-shaped groove 401 away from the second waist-shaped groove 402 to form a connecting port 4031 , and the other end of the third waist-shaped groove 403 is connected to the second waist-shaped groove 402 .

[0039] When the driving rod 7 drives the hollow plate 40 to rise, the sliding rod 30 slides downward in the second waist-shaped groove 402 until it slides to the third waist-shaped groove 403. At this time, due to gravity, the sliding rod 30 slides downward along the third waist-shaped groove 403 and enters the connecting port 4031, that is, enters the first waist-shaped groove 401 to reset.

[0040] Reference Figure 6and Figure 7 The hollow plate 40 is located in the second waist-shaped groove 402 and is hinged with a baffle 4021 through a torsion spring. The torsion spring force is small, and the baffle 4021 is tilted, and the tilting direction is consistent with the tilting direction of the third waist-shaped groove 403. The baffle 4021 can only rotate upward. When the sliding rod 30 enters the second waist-shaped groove 402 and resets, the hollow plate 40 continues to descend, and the sliding rod 30 slides upward relative to the second waist-shaped groove 402, and will drive the baffle 4021 to rotate upward. When the hollow plate 40 finishes descending, the sliding rod 30 is located on the upper side of the baffle 4021. The driving rod 7 drives the hollow plate 40 to rise and reset. Before resetting, the sliding rod 30 will abut against the baffle 4021, and then the hollow plate 40 continues to rise until it resets, driving the rotating plate 20 to rotate upward. At this time, the inclination direction of the sliding groove 201 is consistent with the direction of the third waist-shaped groove 403, and the sliding rod 30 enters the connection along the third waist-shaped groove 403. Then, under the action of the torsion spring, the rotating plate 20 resets, driving the sliding rod 30 to move a certain distance in the first waist-shaped groove 401 and disengage from the connecting port 4031. If the sliding rod 30 is located at the connecting port 4031, then when the hollow plate 40 descends, the sliding rod 30 may directly enter the third waist-shaped groove 403 from the connecting port 4031, affecting normal operation. In practice, when the hollow plate 40 rises and resets, the rotating plate 20 rotates upward a certain distance. At this time, the torsion spring will exert a force on the rotating plate 20, that is, the rotating plate 20 exerts a certain extrusion force on the sliding rod 30 and the inner wall of the third waist-shaped groove 403. However, this extrusion force is small, that is, the friction between the sliding rod 30 and the third waist-shaped groove 403 and the sliding groove 201 is small, and the sliding rod 30 may slip under the action of the gravity component of the extrusion wheel 301.

[0041] Reference Figure 7 and Figure 8 A lifting groove 4011 is provided on the bottom wall of the hollow plate 40 located in the first waist-shaped groove 401. A wedge block 50 is provided in the lifting groove 4011 for lifting and sliding of the hollow plate 40. A compression spring 60 is provided in the lifting groove 4011 of the hollow plate 40. One end of the compression spring 60 is connected to the bottom of the wedge block 50, and the other end of the compression spring 60 is connected to the bottom wall of the lifting groove 4011. A wedge surface 501 is formed on the side of the wedge block 50 close to the connecting port 4031, and a blocking surface 502 is formed on the side of the wedge block 50 away from the connecting port 4031.

[0042] When the sliding rod 30 slides from the third waist-shaped groove 403 into the connecting opening 4031, and then the rotating plate 20 is reset to drive the sliding rod 30 to slide in the first waist-shaped groove 401, the sliding rod 30 contacts the wedge-shaped surface 501 of the wedge block 50, so that the wedge block 50 slides into the lifting groove 4011 to avoid the sliding of the sliding rod 30. When the sliding rod 30 is separated from the wedge block 50, the compression spring 60 acts, and the wedge block 50 extends out of the lifting groove 4011. At this time, the blocking surface 502 can limit the direction of the sliding of the sliding rod 30; because the rotating plate 20 is initially tilted upward, when the hollow plate 40 descends, if there is no wedge block 50 to block the sliding rod 30, the sliding rod 30 may slide in the direction of the connecting opening 4031, resulting in the rotating plate 20 being unable to rotate downward.

[0043] The implementation principle of the plane polishing device of a circular glass in the embodiment of the present application is as follows: the glass is placed on the fixture 2, and then the screw slide 12 drives the installation box 13 to descend, and the driving rod 7 is descended accordingly, and the driving rod 7 drives the hollow plate 40 to descend, and the hollow plate 40 drives the sliding rod 30 to move, that is, the extrusion wheel 301 squeezes the hose part 82, and the branch pipe 41 sprays the polishing liquid to the glass surface; then the polishing disc 3 continues to descend until it abuts against the glass surface, at this time, the toggle mother plate 721 and the toggle sub-plate 911 are in the same plane; the driving motor 131 is operated to drive the polishing disc 3 to rotate, and at the same time, under the action of the first pulley 14, the second pulley 15 and the belt 16, the driving rod 7 rotates, on the one hand, the driving rod 7 drives the linkage gear 6 to rotate, and the linkage gear 6 drives all the fixtures 2 to rotate through the ring plate 51, and cooperates with the rotation of the polishing disc 3 to achieve efficient polishing of the glass, on the other hand, the toggle wheel 72 rotates, and the toggle mother plate 721 cooperates with the toggle sub-plate 911 to drive the blocking plate 91 to slide back and forth, so as to achieve intermittent liquid spraying. The polishing device of the present application can continuously replenish the polishing liquid during the polishing process without lifting the polishing disc 3, which helps to improve the polishing efficiency.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
