Description

Technical Field

[0001] This utility model relates to the field of automated polishing equipment technology, specifically to an automated polishing equipment for the inner hole of a circular ring plate. Background Technology

[0002] In the modern manufacturing industry, with the rapid development of precision machining technology, the requirements for the surface quality of parts are becoming increasingly stringent, especially for various ring-shaped parts, such as circular rings. The smoothness and precision of the inner hole surface directly affect the overall performance and service life of the product. Polishing, as a key process to improve the quality of the inner hole of ring-shaped parts, has an increasingly urgent need for automated and efficient equipment. Developing advanced polishing equipment has become an important direction for enhancing the competitiveness of the manufacturing industry.

[0003] Currently, when polishing the inner hole of a circular ring, the circular ring is usually fixed inside the polishing equipment first. Then, the position of the circular ring is adjusted so that the polishing device can contact the inner hole of the circular ring. Then, the polishing device is started to move, thereby polishing the inner hole of the circular ring.

[0004] However, during the polishing process of the inner hole of the circular ring, since the inner hole size of different circular rings is different, different polishing devices need to be changed when polishing the inner hole of different circular rings, which can easily reduce work efficiency and affect the use of the equipment. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an automated polishing device for the inner hole of a circular ring, so as to solve the technical problem that since the inner hole size of circular rings of different sizes is different, different polishing devices need to be changed when polishing the inner hole of different circular rings, which can easily reduce work efficiency and affect the use of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated polishing device for the inner hole of a circular ring, comprising a frame, a connecting pipe rotatably connected to one end of the frame, an air bladder fixedly connected to the surface of the connecting pipe, a plurality of air holes matching the air bladder being provided on the surface of the connecting pipe, a plurality of polishing devices being provided on the surface of the air bladder, a first gear fixedly connected to the surface of the connecting pipe, a second gear meshing with the surface of the first gear, and the second gear rotatably connected to one end of the frame, a support plate fixedly connected to one end of the frame, a motor matching the second gear being installed on the top of the support plate, and the output section of the motor being connected to one end of the second gear.

[0007] By adopting the above technical solution, when polishing the inner hole of the annular plate, multiple annular plates can be placed on the surface of the connecting tube first, and then gas is supplied into the connecting tube. The gas enters the airbag through the air hole and inflates, so the airbag can be adjusted according to the size of the inner hole of the annular plate. This allows the polishing device on the surface of the airbag to fit closely with the surface of the inner hole of the annular plate. Then, the motor is started to drive the second gear to rotate, which causes the first gear to drive the connecting tube to rotate synchronously. Therefore, the polishing device can perform circumferential polishing in the inner hole of the annular plate, thus effectively polishing the inner hole of the annular plate and ensuring the uniformity of polishing. This structure can adjust the degree of inflation of the airbag according to the actual size of the inner hole of the annular plate, thereby meeting the needs of different annular plate inner hole sizes, which facilitates the flexibility and applicability of the equipment and helps to improve work efficiency.

[0008] The present invention is further configured such that clamping plates are movably connected to both sides of the frame body, and each clamping plate is connected to the frame body through a set of telescopic rods.

[0009] By adopting the above technical solution, when multiple circular rings are placed on the surface of the connecting tube and the airbag expands to fit the inner hole of the circular ring, the telescopic rod can be activated to drive the clamping plate to move. The clamping plate can then stably clamp and position the circular rings, preventing them from shaking or shifting during the polishing process and ensuring the precision and quality of the polishing.

[0010] The present invention is further provided that positioning holes are provided at the four corners of the bottom of the frame, and anti-slip pads are provided at the bottom of the frame.

[0011] By adopting the above technical solution, fixing parts, such as expansion bolts, can be set in the positioning holes to achieve fixed installation of the frame. At the same time, the design of the anti-slip pad can increase the friction between the frame and the contact surface, which can help improve the stability of equipment operation.

[0012] The present invention is further provided that an elastic gasket is provided between the airbag and the polishing device.

[0013] By adopting the above technical solution, the polishing device can better adapt to the deformation of the airbag, thereby ensuring the fit between the polishing device and the inner hole surface of the ring plate, improving the polishing effect, and also playing a buffering role to reduce damage to the airbag.

[0014] The present invention is further configured such that an air pump device is installed on the surface of the frame, and one end of the connecting pipe is connected to the air pump device through a bearing.

[0015] By adopting the above technical solution, gas can be delivered to the connecting pipe and the airbag through the air pump device according to actual needs, so that the airbag can be adjusted according to the size of the inner hole of the ring plate. At the same time, the bearing connection method can ensure that the connecting pipe can rotate, which facilitates better polishing of the inner hole of the ring plate.

[0016] The present invention is further provided that rubber pads are provided on both adjacent sides of the clamping plate.

[0017] By adopting the above technical solution, the friction between a set of clamping plates and the inner hole of the ring plate can be increased, thereby fixing the ring plate when polishing the inner hole of the ring plate and avoiding the ring plate from affecting the polishing due to its synchronous movement with the airbag.

[0018] The present invention is further configured such that the airbag, the elastic pad and the polishing device are all bonded together by a silicone rubber adhesive.

[0019] By adopting the above technical solution, the silicone rubber adhesive has good bonding performance, which can firmly bond the airbag, elastic gasket and polishing device together, thus preventing them from loosening or falling off during use, improving the reliability and stability of the equipment. At the same time, the silicone rubber adhesive has flexibility and can adapt to the deformation of the airbag, avoiding affecting its use.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention places multiple circular rings on the surface of a connecting tube and then supplies gas into the connecting tube. The gas enters the airbag through vents, causing it to inflate. This allows the airbag to be adjusted according to the size of the inner hole of the circular rings, ensuring the polishing device on the airbag surface fits snugly against the inner hole surface of the circular rings. A motor is then activated, driving a second gear to rotate, which in turn causes the first gear to rotate the connecting tube synchronously. This allows the polishing device to perform circumferential polishing within the inner hole of the circular rings, effectively polishing the inner hole and ensuring uniform polishing. This structure allows the airbag's inflation degree to be adjusted according to the actual size of the inner hole of the circular rings, thus accommodating different inner hole sizes and improving the flexibility and applicability of the equipment.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] An automated polishing device for the inner hole of a circular ring, such as Figures 1-4 As shown, the device includes a frame 1, with positioning holes 2 at the four corners of the bottom of the frame 1. Fixing parts such as expansion bolts and bolts can be installed and fixed in the positioning holes 2 to fix the frame 1. The bottom of the frame 1 is provided with anti-slip pads 3, which can increase the friction between the frame 1 and the contact surface, thereby preventing slippage during use and improving the stability of the equipment operation.

[0030] Subsequently, a connecting pipe 7 is rotatably connected to one end of the frame 1. An air bladder 9 is fixedly connected to the surface of the connecting pipe 7. Several air holes 8 are provided on the surface of the connecting pipe 7 to fit the air bladder 9. Therefore, in use, multiple annular plates can be inserted sequentially through the connecting pipe 7. Then, gas is supplied into the connecting pipe 7, and the gas enters the interior of the air bladder 9 through the air holes 8, causing the air bladder 9 to inflate. Several polishing devices 11 are provided on the surface of the air bladder 9. The expansion of the air bladder 9 can drive the polishing devices 11 to move until the polishing devices 11 can fit against the inner hole surfaces of the multiple annular plates. Thus, the degree of expansion of the air bladder 9 can be adjusted according to the actual size of the inner hole of the annular plate, thereby meeting the needs of different annular plate inner hole sizes and improving the flexibility of the equipment. For both safety and applicability, a first gear 12 is fixedly connected to the surface of the connecting pipe 7, and a second gear 13 meshes with the surface of the first gear 12. The second gear 13 is rotatably connected to one end of the frame 1, and a support plate 15 is fixedly connected to one end of the frame 1. A motor 14 that meshes with the second gear 13 is installed on the top of the support plate 15, and the output section of the motor 14 is connected to one end of the second gear 13. When the motor 14 is started, it drives the second gear 13 to rotate, which in turn causes the first gear 12 that meshes with the second gear 13 to drive the connecting pipe 7, the airbag 9, and the polishing device 11 to rotate synchronously. Therefore, the polishing device 11 can perform circumferential polishing in the inner hole of the annular plate, thereby effectively polishing the inner hole of the annular plate and ensuring the uniformity of polishing.

[0031] An air pump device 16 is installed on the surface of the frame 1, so gas can be delivered into the connecting pipe 7 through the air pump device 16. One end of the connecting pipe 7 is connected to the air pump device 16 through a bearing, which allows the connecting pipe 7 to rotate inside the air pump device 16, thus avoiding affecting the polishing of the inner hole of the annular plate. At the same time, the bearing here can be a bearing with a sealing cap, and additional seals can be added to both ends of the bearing to increase the sealing of the connection between the connecting pipe 7, the bearing, and the air pump device 16, so as to prevent gas leakage from affecting the use of the equipment.

[0032] Furthermore, clamping plates 5 are movably connected to both sides of the frame 1. Each clamping plate 5 is connected to the frame 1 via a set of telescopic rods 4. Therefore, when the airbag 9 inflates to polish the inner hole of the ring piece, the telescopic rods 4 can be activated to drive the clamping plates 5 to move synchronously until the set of clamping plates 5 stably clamps and positions the ring piece, preventing the ring piece from shaking or shifting during the polishing process, and ensuring the accuracy and quality of the polishing. At the same time, rubber pads 6 are provided on adjacent sides of the set of clamping plates 5, which can increase the friction between the set of clamping plates 5 and the inner hole of the ring piece, making it easier to stably clamp and fix the ring piece, and avoiding the impact of the ring piece moving synchronously with the airbag 9 on the polishing.

[0033] Meanwhile, an elastic pad 10 is provided between the airbag 9 and the polishing device 11, which allows the polishing device 11 to better conform to the deformation of the airbag 9, thereby ensuring the fit between the polishing device 11 and the inner hole surface of the annular plate and improving the polishing effect. The airbag 9, the elastic pad 10 and the polishing device 11 are all bonded together with silicone rubber adhesive. The rubber adhesive has good bonding performance and can firmly bond the airbag 9, the elastic pad 10 and the polishing device 11 together, thus preventing them from loosening or falling off during use and improving the reliability and stability of the equipment. At the same time, the silicone rubber adhesive has flexibility and can adapt to the deformation of the airbag 9 to avoid affecting its use.

[0034] In this embodiment, the airbag 9 can be made of high-strength polyurethane rubber, which has good elasticity, wear resistance and corrosion resistance, making it easier to extend the service life of the equipment.

[0035] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
