Abstract

The present invention relates to the technical field of accessory polishing, and discloses a polishing device for manufacturing and processing engineering machinery accessories and its usage method, including a mounting plate. A motor is fixedly connected to the top of the mounting plate, and a driving gear is fixedly connected to the output shaft of the motor. Before use, the mounting plate is installed on the robotic arm, and it is ensured that the external polishing solution can enter the inside of the circulation pipe through the feed pipe. When the robotic arm places the wool wheel on the surface of the accessory, the power supply of the motor is turned on. The centrifugal force generated by the rotating mounting box at high speed will force the piston block to slide outward along the inner wall of the sliding square pipe.

Description

Technical Field

[0001] The present invention relates to the technical field of accessory polishing equipment, and particularly to a polishing device for manufacturing and processing engineering machinery accessories and a usage method thereof. Background Technique

[0002] With the development of society, people's living standards have been increasing day by day. People's various needs have also increased accordingly, and at the same time, the requirements for product quality have been continuously improving. Steel is an indispensable material in production operations. However, during the process of producing steel plates, the plates need to be polished to remove impurities and burrs on the plates. The traditional polishing device consists of a stroke mechanism, a power mechanism, and a polishing mechanism. During the polishing operation, the stroke mechanism drives the polishing mechanism to displace according to the preset settings and polish the workpiece. This is also a polishing device with the widest scope of application at present, having the advantages of simple structure, convenient use, and low cost.

[0003] When performing high-precision polishing on accessories, it is necessary to spray a polishing solution on the outside of the accessories in advance, and then use a wool grinding wheel to finely polish the outer wall of the accessories. When the high-speed rotating wool grinding wheel contacts the polishing solution, the solution will spread around, resulting in low application efficiency of the polishing solution and the wool wheel. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a polishing device for manufacturing and processing engineering machinery accessories, including a mounting plate. A motor is fixedly connected to the top of the mounting plate. The output shaft of the motor is fixedly connected to a driving gear. A driving tube is rotatably connected to the inner wall of the through hole of the mounting plate. A toothed ring is fixedly connected to the outer wall of the driving tube. A feed tube is rotatably connected to the inner wall of the driving tube;

[0005] A grinding mechanism, the grinding mechanism includes a flow tube connected through the bottom of the driving tube. One end of the flow tube away from the driving tube is connected through to an installation box. A chassis is fixedly connected to the bottom of the installation box. A wool wheel is fixedly connected to the bottom of the chassis;

[0006] The spraying mechanism includes a mounting plate fixedly connected to the top of the chassis, a fixing frame fixedly connected to the top of the mounting plate, a plurality of sliding square tubes are connected through the side wall of the fixing frame, a piston block is slidably connected to the inner wall of the sliding square tube, a sliding groove is provided on the top of the mounting plate, a transmission tube is fixedly connected to the inner wall of the mounting plate, an atomizer is connected through the end of the transmission tube away from the sliding groove, an L-shaped slide is slidably connected to the inner wall of the sliding groove, a spring telescopic rod is fixedly connected to the side wall of the L-shaped slide, a control component is rotatably connected to the top of the mounting plate, and a constraint component is fixedly connected to the side wall of the mounting box. A grinding mechanism and a spraying mechanism are provided inside the equipment by utilizing the characteristic that the equipment generates a large centrifugal force during polishing. Before use, the mounting plate is mounted on the robotic arm, and it is ensured that the external polishing solution can enter the interior of the circulation tube through the feed pipe. When the arm places the wool wheel on the surface of the accessory, the power of the motor is turned on, and the motor drives the driving tube and the circulation tube to rotate through the driving gear. The rotating circulation tube drives the chassis and the wool wheel to rotate through the mounting box, and the rotating wool wheel polishes the outer wall of the accessory; the centrifugal force generated by the high-speed rotating mounting box will force the piston block to slide outward along the inner wall of the sliding square tube, and the sliding piston block drives the L-shaped slide plate to move synchronously outward along the inner wall of the sliding groove through the spring telescopic rod, so that the L-shaped slide plate no longer covers the entrance of the transmission tube. At this time, the polishing solution on the top of the mounting plate can reach the atomizer directly through the transmission tube. The polishing solution sprayed outward from the atomizer will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel, thereby improving the polishing quality of the equipment.

[0007] Preferably, the control component includes a gear column rotatably connected to the top of the mounting plate, a gear rod is fixedly connected to the inner wall of several piston blocks, the inner wall of the mounting plate is rotatably connected to the outer wall of the output shaft of the motor, and a control component is provided inside the device by utilizing the characteristic that the above-mentioned piston block moves outward under centrifugal force. When the piston block moves outward, the piston block will drive the corresponding gear rod to move synchronously, and in the process of the gear rod moving horizontally, the gear rod will drive the gear column to rotate, and the rotation speed of the gear column will limit the speed of the outward horizontal movement of multiple gear rods. Through the application of the above-mentioned gear column and gear rod, the gear column can simultaneously control the speed of multiple piston blocks and gear rods sliding outward along the inner wall of the sliding square tube, so as to avoid uneven outward movement speeds of the piston blocks, causing the center of rotation of the wool wheel to shift, affecting the polishing efficiency of the equipment.

[0008] Preferably, the constraint component includes a first hydraulic telescopic rod fixedly connected to the side wall of the piston block. A first spring is fixedly connected to the side wall of the first hydraulic telescopic rod. The end of the first hydraulic telescopic rod away from the piston block is connected through a transmission round pipe. By using the characteristic that the piston block moves along the outer wall of the sliding square pipe, at this time, the liquid on the top of the mounting plate will enter the groove formed by the piston block and the sliding square pipe. As more liquid enters the circulation pipe and the groove, the inertia generated by the rotation of the mounting box will also increase synchronously, increasing the pressure exerted by the wool wheel during grinding. Through the application of the above components, when the wool wheel faces irregular fittings, the large inertia prevents the wool wheel from being blocked too much, resulting in a decrease in the rotation speed of the mounting box.

[0009] Preferably, the constraint component further includes a fixing plate fixedly connected to the side wall of the mounting box. A second hydraulic telescopic rod is fixedly connected to the bottom of the fixing plate. The end of the second hydraulic telescopic rod away from the fixing plate is fixedly connected to a mounting block. By using the characteristic that a single tooth post controls the outward movement of multiple tooth rods, while ensuring the outward movement speed of multiple piston blocks, the synchronously outward moving piston blocks ensure that the depths of the grooves formed by the piston blocks and the mounting plate inside the equipment are equal, and the volumes of the polishing solution accumulated in the multiple grooves are equal, ensuring that the center of rotation of the mounting box remains unchanged.

[0010] Preferably, the constraint component further includes a constraint ring fixedly connected to the side walls of several mounting blocks. The inner wall of the constraint ring is slidably connected to the outer wall of the mounting box. The outer wall of the transmission round pipe is fixedly connected to the inner wall of the mounting box. The outer wall of the tooth ring is meshed with the outer wall of the driving gear. By using the characteristic that the polishing solution and centrifugal force drive the piston block to move outward, a constraint component is provided inside the equipment. When the piston block moves outward, the piston block will squeeze the corresponding first hydraulic telescopic rod, causing the solution inside the first hydraulic telescopic rod to enter the second hydraulic telescopic rod through the transmission round pipe, and forcing the second hydraulic telescopic rod to extend. The extended second hydraulic telescopic rod drives the constraint ring to slide downward along the outer wall of the mounting box through the mounting block. The sliding-down constraint ring will limit the wool roots floating outward at the bottom wool wheel. Through the application of the above components, it is avoided that the soft wool wheel is affected by centrifugal force, and multiple wool roots spread around, reducing the contact surface between the wool wheel and the fitting, and making it difficult to effectively polish the bottom parts.

[0011] Preferably, the end of the transmission round pipe away from the first hydraulic telescopic rod is connected through the side wall of the second hydraulic telescopic rod. The end of the first hydraulic telescopic rod away from the piston block is fixedly connected to the inner wall of the mounting box. The bottom of the sliding groove is connected through the inner wall of the transmission pipe.

[0012] Preferably, the side wall of the rack is meshed and connected with the outer wall of the column gear. One end of the first spring telescopic rod away from the L-shaped slide plate is fixedly connected to the side wall of the piston block. One end of the fixed frame away from the mounting plate is fixedly connected to the top inner wall of the mounting box. After the equipment finishes polishing, the first hydraulic telescopic rod releases. Next, each component resets, and the restraint ring no longer restricts the wool wheel, so that the wool roots of the wool wheel can disperse on their own under the influence of the residual centrifugal force, avoiding the adhesion and hardening of multiple wool roots due to the adhesion of the polishing solution and affecting the subsequent grinding effect.

[0013] A method for using a polishing device for manufacturing and processing construction machinery parts includes the following steps:

[0014] S1: Start the device, install the motor on the robotic arm, and ensure that the external polishing solution can enter the inside of the circulation pipe through the feed pipe.

[0015] S2: Connect the power supply. The motor drives the drive pipe and the circulation pipe to rotate through the drive gear and the gear ring. The rotating circulation pipe drives the mounting box and the wool wheel to start the polishing process.

[0016] The present invention has the following beneficial effects:

[0017] (1) Utilizing the characteristic that the equipment generates a large centrifugal force during polishing, the present invention is provided with a grinding mechanism and a spraying mechanism inside the equipment. Before use, install the mounting plate on the robotic arm and ensure that the external polishing solution can enter the inside of the circulation pipe through the feed pipe. When the robotic arm places the wool wheel on the surface of the part, connect the power supply of the motor. The motor drives the drive pipe and the circulation pipe to rotate through the drive gear. The rotating circulation pipe drives the chassis and the wool wheel to rotate through the mounting box. The rotating wool wheel polishes the outer wall of the part; the centrifugal force generated by the rapidly rotating mounting box will force the piston block to slide outward along the inner wall of the sliding square pipe. The sliding piston block drives the L-shaped slide plate to move outward synchronously along the inner wall of the sliding groove through the first spring telescopic rod, so that the L-shaped slide plate no longer covers the inlet of the transfer pipe. At this time, the polishing solution on the top of the mounting plate can reach the atomizer directly through the transfer pipe. The polishing solution sprayed outward by the atomizer will diffuse in all directions under the action of centrifugal force. Through the application of the above components, the polishing solution diffusing from the center of the equipment to all around will increase the contact area between the solution and the wool wheel and improve the polishing quality of the equipment.

[0018] (2)The present invention utilizes the characteristic that the above-mentioned piston block moves outward under the centrifugal force. A control component is provided inside the device. When the piston block moves outward, the piston block will drive the corresponding rack to move synchronously. During the transverse movement of the rack, the rack will drive the tooth column to rotate, and the rotation speed of the tooth column will limit the speed of multiple racks moving outward. Through the application of the above-mentioned tooth column and rack, the tooth column can simultaneously control the speed of multiple piston blocks and racks sliding outward along the inner wall of the sliding square tube, avoiding unequal speeds of the piston blocks moving outward, resulting in the deviation of the rotation center of the wool wheel and affecting the polishing efficiency of the device.

[0019] (3)The present invention utilizes the characteristic that the above-mentioned piston block moves along the outer wall of the sliding square tube. At this time, the liquid on the top of the mounting disk will enter the groove formed by the piston block and the sliding square tube. As more liquid enters the circulation pipe and the groove, the inertia generated by the rotation of the mounting box will also increase synchronously, increasing the pressure exerted by the wool wheel during grinding. Through the application of the above components, when the wool wheel faces irregular fittings, the large inertia prevents the wool wheel from being blocked too much, resulting in a decrease in the rotation speed of the mounting box. Additionally, due to the characteristic that a single tooth column controls the outward movement of multiple racks, while ensuring the speed of multiple piston blocks moving outward, the synchronously moving piston blocks ensure that the depths of multiple grooves formed by the piston blocks and the mounting disk inside the device are equal, and the volumes of the polishing solution accumulated in multiple grooves are equal, ensuring that the rotation center of the mounting box remains unchanged.

[0020] (4)The present invention utilizes the characteristic that the above-mentioned polishing solution and centrifugal force drive the piston block to move outward. A constraint component is provided inside the device. When the piston block moves outward, the piston block will squeeze the corresponding hydraulic telescopic rod 1, causing the solution inside the hydraulic telescopic rod 1 to enter the hydraulic telescopic rod 2 through the transmission round tube, and forcing the hydraulic telescopic rod 2 to extend. The extended hydraulic telescopic rod 2 drives the constraint ring to slide downward along the outer wall of the mounting box through the mounting block. The sliding constraint ring will limit the wool roots floating outward at the bottom. Through the application of the above components, it is avoided that the soft wool wheel is affected by the centrifugal force, and multiple wool roots spread in all directions, reducing the contact surface between the wool wheel and the fitting, and making it difficult to effectively polish the bottom parts. After the device finishes polishing, the hydraulic telescopic rod 1 releases. Next, each component resets, and the constraint ring no longer restricts the wool wheel, allowing the wool roots of the wool wheel to disperse on their own under the influence of the residual centrifugal force, avoiding the adhesion and hardening of multiple wool roots due to the adhesion of the polishing solution, which affects the subsequent grinding effect.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0034] Embodiment 1. Please refer to Figure 1 - Figure 5 , the present invention is a polishing device for manufacturing and processing construction machinery accessories, including a mounting plate 1. A motor 11 is fixedly connected to the top of the mounting plate 1. The output shaft of the motor 11 is fixedly connected to a driving gear 12. A driving tube 13 is rotatably connected to the inner wall of the through hole of the mounting plate 1. A toothed ring 14 is fixedly connected to the outer wall of the driving tube 13. A feeding tube 15 is rotatably connected to the inner wall of the driving tube 13;

[0035] A grinding mechanism 2, the grinding mechanism 2 includes a flow tube 21 connected through the bottom of the driving tube 13. One end of the flow tube 21 away from the driving tube 13 is connected through to an installation box 22. A chassis 23 is fixedly connected to the bottom of the installation box 22. A wool wheel 24 is fixedly connected to the bottom of the chassis 23;

[0036] The spraying mechanism 3 includes a mounting plate 31 fixedly connected to the top of the chassis 23, a fixing frame 32 fixedly connected to the top of the mounting plate 31, a plurality of sliding square tubes 33 are connected to the side wall of the fixing frame 32, a piston block 34 is slidably connected to the inner wall of the sliding square tube 33, a sliding groove 35 is provided on the top of the mounting plate 31, a transmission pipe 36 is fixedly connected to the inner wall of the mounting plate 31, and an atomizer 37 is connected to the end of the transmission pipe 36 away from the sliding groove 35. An L-shaped slide 38 is slidably connected to the inner wall, a spring telescopic rod 39 is fixedly connected to the side wall of the L-shaped slide 38, the top of the mounting plate 31 is rotatably connected to the control component 4, and the side wall of the mounting box 22 is fixedly connected to the constraint component 5. During polishing, the equipment generates a large centrifugal force. A polishing mechanism 2 and a spraying mechanism 3 are provided inside the equipment. Before use, the mounting plate 1 is installed on the robot arm, and it is ensured that the external polishing solution can enter the circulation tube 21 through the feed pipe 15. When the mechanical arm places the wool wheel 24 on the surface of the accessory, the power of the motor 11 is turned on. The motor 11 drives the driving tube 13 and the circulation tube 21 to rotate through the driving gear 12. The rotating circulation tube 21 drives the chassis 23 and the wool wheel 24 to rotate through the installation box 22, and the rotating wool wheel 24 polishes the outer wall of the accessory; the centrifugal force generated by the high-speed rotating installation box 22 will force the piston block 34 to slide outward along the inner wall of the sliding square tube 33, and the sliding piston block 34 drives the L-shaped slide plate 38 to move outward along the inner wall of the sliding groove 35 synchronously through the spring telescopic rod 1 39, so that the L-shaped slide plate 38 no longer covers the inlet of the transmission tube 36. At this time, the polishing solution on the top of the mounting plate 31 can directly reach the atomizer 37 through the transmission tube 36. The polishing solution sprayed outward by the atomizer 37 will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel 24, thereby improving the polishing quality of the equipment.

[0037] For example 2, please refer to Figure 6 - Figure 9, the present invention is a polishing device for manufacturing and processing construction machinery parts. Based on Embodiment 1, the control component 4 includes a tooth column 41 rotatably connected to the top of the mounting plate 31. Tooth rods 42 are fixedly connected to the inner walls of several piston blocks 34. The inner wall of the mounting plate 1 is rotatably connected to the outer wall of the output shaft of the motor 11. Utilizing the characteristic that the piston blocks 34 move outward under centrifugal force, a control component 4 is arranged inside the device. When the piston blocks 34 move outward, the piston blocks 34 will drive the corresponding tooth rods 42 to displace synchronously. During the lateral movement of the tooth rods 42, the tooth rods 42 will drive the tooth column 41 to rotate. And the rotation speed of the tooth column 41 will limit the speed of the outward lateral movement of multiple tooth rods 42. Through the application of the tooth column 41 and the tooth rods 42, the tooth column 41 can simultaneously control the speed of multiple piston blocks 34 and tooth rods 42 sliding outward along the inner wall of the sliding square tube 33, avoiding the unequal speed of the outward movement of the piston blocks 34, resulting in the deviation of the rotation center of the wool wheel 24 and affecting the polishing efficiency of the device.

[0038] The constraint component 5 includes a first hydraulic telescopic rod 51 fixedly connected to the side wall of the piston block 34. A first spring 52 is fixedly connected to the side wall of the first hydraulic telescopic rod 51. The end of the first hydraulic telescopic rod 51 far from the piston block 34 is connected through a transmission circular tube 53. Utilizing the characteristic that the piston block 34 moves along the outer wall of the sliding square tube 33, at this time, the liquid on the top of the mounting plate 31 will enter the groove formed by the piston block 34 and the sliding square tube 33. As more liquid enters the circulation pipe 21 and the groove, the inertia generated by the rotation of the mounting box 22 will also increase synchronously, increasing the pressure exerted by the wool wheel 24 during grinding. Through the application of the above components, it is ensured that when the wool wheel 24 faces irregular parts, the large inertia can prevent the wool wheel 24 from being blocked too much, resulting in a decrease in the rotation speed of the mounting box 22.

[0039] The constraint component 5 further includes a fixing plate 54 fixedly connected to the side wall of the mounting box 22. A second hydraulic telescopic rod 55 is fixedly connected to the bottom of the fixing plate 54. The end of the second hydraulic telescopic rod 55 far from the fixing plate 54 is fixedly connected to a mounting block 56. By the characteristic that a single tooth column 41 controls the outward movement of multiple tooth rods 42, while ensuring the speed of the outward movement of multiple piston blocks 34, the synchronously outward moving piston blocks 34 ensure that the depths of the grooves formed by multiple piston blocks 34 and the mounting plate 31 inside the device are equal, and the volumes of the polishing solution accumulated in multiple grooves are equal, ensuring that the rotation center of the mounting box 22 remains unchanged.

[0040] The constraint component 5 further includes a constraint ring 57 fixedly connected to the side walls of several mounting blocks 56. The inner wall of the constraint ring 57 is slidably connected to the outer wall of the mounting box 22. The outer wall of the transmission circular tube 53 is fixedly connected to the inner wall of the mounting box 22. The outer wall of the gear ring 14 is meshed with the outer wall of the driving gear 12. By utilizing the characteristics of the above polishing solution and the centrifugal force to drive the piston block 34 to move outward, a constraint component 5 is provided inside the device. When the piston block 34 moves outward, the piston block 34 will squeeze the corresponding first hydraulic telescopic rod 51, so that the solution inside the first hydraulic telescopic rod 51 enters the second hydraulic telescopic rod 55 through the transmission circular tube 53, and forces the second hydraulic telescopic rod 55 to extend. The extended second hydraulic telescopic rod 55 drives the constraint ring 57 to slide downward along the outer wall of the mounting box 22 through the mounting block 56. The sliding-down constraint ring 57 will restrict the hair roots of the bottom wool wheel 24 from floating outward. Through the application of the above components, it is avoided that the soft wool wheel 24 is affected by the centrifugal force, and multiple hair roots spread around, reducing the contact surface between the wool wheel 24 and the accessories and making it difficult to effectively polish the bottom parts.

[0041] One end of the transmission circular tube 53 far from the first hydraulic telescopic rod 51 is connected to the side wall of the second hydraulic telescopic rod 55 in a penetrating manner. One end of the first hydraulic telescopic rod 51 far from the piston block 34 is fixedly connected to the inner wall of the mounting box 22. The bottom of the sliding groove 35 is connected to the inner wall of the transmission pipe 36 in a penetrating manner.

[0042] The side wall of the rack 42 is meshed with the outer wall of the tooth column 41. One end of the first spring telescopic rod 39 far from the L-shaped sliding plate 38 is fixedly connected to the side wall of the piston block 34. One end of the fixing frame 32 far from the mounting disc 31 is fixedly connected to the top of the inner wall of the mounting box 22. After the device finishes polishing, the first hydraulic telescopic rod 51 releases. Next, each component resets, and the constraint ring 57 no longer restricts the wool wheel 24, so that the hair roots of the wool wheel 24 can disperse by themselves under the influence of the remaining centrifugal force, avoiding the adhesion and hardening of multiple hair roots due to the adhesion of the polishing solution and affecting the subsequent grinding effect.

[0043] The usage method of the polishing device for manufacturing and processing construction machinery accessories includes the following steps:

[0044] S1: Start the device, install the motor 11 on the robotic arm, and ensure that the external polishing solution can enter the circulation pipe 21 through the feed pipe 15;

[0045] S2: Connect the power supply. The motor 11 drives the drive pipe 13 and the circulation pipe 21 to rotate through the drive gear 12 and the gear ring 14. The rotating circulation pipe 21 drives the mounting box 22 and the wool wheel 24 to start the polishing process.

[0046] A specific application of this embodiment is as follows: before use, the mounting plate 1 is mounted on the robot arm, and external polishing solution is ensured to enter the circulation tube 21 through the feed pipe 15. When the robot arm places the wool wheel 24 on the surface of the accessory, the power of the motor 11 is turned on, and the motor 11 drives the driving tube 13 and the circulation tube 21 to rotate through the driving gear 12. The rotating circulation tube 21 drives the chassis 23 and the wool wheel 24 to rotate through the mounting box 22. The rotating wool wheel 24 performs a polishing process on the outer wall of the accessory; the centrifugal force generated by the high-speed rotating mounting box 22 forces the piston The block 34 slides outward along the inner wall of the sliding square tube 33, and the sliding piston block 34 drives the L-shaped slide plate 38 to move outward synchronously along the inner wall of the sliding groove 35 through the spring telescopic rod 39, so that the L-shaped slide plate 38 no longer covers the entrance of the transmission pipe 36. At this time, the polishing solution on the top of the mounting plate 31 can reach the atomizer 37 directly through the transmission pipe 36. The polishing solution sprayed outward by the atomizer 37 will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel 24, thereby improving the polishing quality of the equipment.

[0047] Taking advantage of the characteristic that the piston block 34 moves outward under centrifugal force, a control component 4 is provided inside the device. When the piston block 34 moves outward, the piston block 34 will drive the corresponding gear rod 42 to move synchronously. During the transverse movement of the gear rod 42, the gear rod 42 will drive the gear column 41 to rotate, and the rotation speed of the gear column 41 will limit the speed at which multiple gear rods 42 move outward. Through the application of the above-mentioned gear column 41 and gear rod 42, the gear column 41 can simultaneously control the speed at which multiple piston blocks 34 and gear rods 42 slide outward along the inner wall of the sliding square tube 33, thereby avoiding uneven outward movement speeds of the piston block 34, causing the center of rotation of the wool wheel 24 to shift, thereby affecting the polishing efficiency of the equipment.

[0048] By utilizing the characteristic that the piston block 34 moves along the outer wall of the sliding square tube 33, the liquid on the top of the mounting plate 31 will enter the groove formed by the piston block 34 and the sliding square tube 33. As more liquid enters the circulation tube 21 and the groove, the inertia generated by the rotation of the mounting box 22 will also increase synchronously, thereby increasing the pressure applied by the wool wheel 24 during polishing. Through the application of the above-mentioned components, the wool wheel 24 can avoid excessive obstruction of the wool wheel 24 when facing irregular accessories due to its larger inertia, which causes the rotation speed of the mounting box 22 to decrease. In addition, the characteristic that a single tooth column 41 controls the outward movement of multiple gear rods 42 can ensure the outward movement speed of multiple piston blocks 34 while simultaneously ensuring the outward movement speed of the multiple piston blocks 34. The synchronous outward movement of the piston blocks 34 ensures that the depths of the multiple grooves formed by the piston blocks 34 and the mounting plate 31 inside the equipment are equal, and the volumes of the polishing solutions accumulated in the multiple grooves are equal, thereby ensuring that the center of rotation of the mounting box 22 remains unchanged.

[0049] Taking advantage of the characteristics of the above polishing solution and the centrifugal force that drives the piston block 34 to move outwards, a constraint component 5 is provided inside the device. When the piston block 34 moves outwards, the piston block 34 will squeeze the corresponding first hydraulic telescopic rod 51, causing the solution inside the first hydraulic telescopic rod 51 to enter the second hydraulic telescopic rod 55 through the transmission round tube 53, and forcing the second hydraulic telescopic rod 55 to extend. The extended second hydraulic telescopic rod 55 drives the constraint ring 57 to slide down along the outer wall of the installation box 22 through the installation block 56, and the sliding-down constraint ring 57 will limit the wool roots that float outwards from the bottom wool wheel 24. Through the application of the above components, it is avoided that the soft wool wheel 24 is affected by the centrifugal force, and multiple wool roots diffuse around, reducing the contact surface between the wool wheel 24 and the accessories, making it difficult to effectively polish the components at the bottom; after the device finishes polishing, the first hydraulic telescopic rod 51 releases. Next, each component resets, and the constraint ring 57 no longer restricts the wool wheel 24, enabling the wool roots of the wool wheel 24 to disperse on their own under the influence of the residual centrifugal force, avoiding the adhesion and hardening of multiple wool roots due to the adhesion of the polishing solution and affecting the subsequent grinding effect.
