[0002] Some rice cookers have a metal outer ring installed on the outside. The circular metal outer ring can be quickly polished using a conventional rotating platform and polishing equipment. However, when the irregularly shaped rectangular outer ring of the rice cooker is installed on the rotating platform, it cannot perform regular circular motion. A robotic arm is needed to adjust and align different positions of the rice cooker outer ring with the polishing plate for polishing. In the process of fixing the rice cooker outer ring and adjusting the different parts of the outer ring to align with the polishing plate, the twisting range of each component of the robotic arm is large, resulting in a large footprint of the equipment and high cost of the robotic arm itself. To solve the above problems, this utility model proposes the following technical solution. Utility Model Content

[0018] Please see Figures 1-4 The present invention provides the following technical solution: a polishing device for manufacturing and processing electrical appliance casings, comprising a lower support protective plate 1, a contoured support ring 2 slidably connected to the top of the lower support protective plate 1, an inner drive tooth 21 fixedly connected to the inner wall of the contoured support ring 2, an outer drive tooth 22 fixedly connected to the outer wall of the contoured support ring 2, a casing ring support frame plate 3 fixedly connected to the top of the contoured support ring 2, an inner gear 4 installed at the top of the lower support protective plate 1, an outer gear 41 installed at the top of the lower support protective plate 1, the inner gear 4 and the outer gear 41 respectively meshing with the inner drive tooth 21 and the outer drive tooth 22, and a polishing roller 5 provided above the lower support protective plate 1.
[0019] In this implementation plan: The operator places the electrical appliance housing ring around the outer side of the housing ring support frame 3, the support airbag ring 31, and the friction washer 34. Then, gas is supplied to the support airbag ring 31 via the connecting air pipe 32 and the gas delivery pipe 33. The inflated support airbag ring 31 compresses the inner wall of the electrical appliance housing ring to position it. Subsequently, the drive motor rotates the internal gear 4 and the external gear 41. The internal gear 4 and the external gear 41 limit the movement of the contour support ring 2 from the inside and outside, respectively, restricting its direction of movement and preventing free swinging. The internal gear 4 and the external gear 41, in conjunction with the internal drive gear 21 and the external drive gear 22, drive the contour support ring 2 and the housing ring support frame 3 to circulate at the top of the lower support protective plate 1. Simultaneously, the grinding roller 5, whose axis is located on the connecting line between the internal gear 4 and the external gear 41... The high-speed rotation automatically polishes the electrical housing ring. After polishing, the internal gear 4 and the polishing roller 5 stop running. The gas in the support airbag ring 31 is discharged from the connecting air pipe 32 and the air supply pipe 33. After the worker removes the polished electrical housing ring, a new electrical housing ring is replaced. The device can automatically polish non-circular electrical housing rings by driving them to move along a trajectory. It has a simple structure and can effectively reduce the production and use costs of the device. In actual use, different support frame plates 3 are set according to the shape of the actual product. The support frame plate 3 itself is an internal support structure with low precision requirements. During processing, it can be formed by casting metal material using a pre-processed electrical housing ring, followed by deburring, polishing and other finishing processes. Alternatively, it can be made by 3D printing, depending on the actual production, to reduce the processing cost of the support frame plate 3.
[0020] A lubricating washer 23 is fixedly connected to the bottom of the contour support ring 2, and the bottom of the lubricating washer 23 is in contact with the top of the lower support protective plate 1. By setting the lubricating washer 23, the friction between the contour support ring 2 and the lower support protective plate 1 can be reduced, making the movement of the contour support ring 2 on the top of the lower support protective plate 1 smoother. During use, the staff uses tools to clean the top surface of the lower support protective plate 1 to prevent dust and debris splashed from the top of the lower support protective plate 1 from hindering the movement of the contour support ring 2.
[0021] A support airbag ring 31 is fixedly connected to the outer wall of the outer shell ring support frame plate 3, and a connecting air pipe 32 is fixedly connected to the inner wall of the support airbag ring 31. The connecting air pipe 32 passes through the outer shell ring support frame plate 3 and extends outward. When the support airbag ring 31 is not inflated, its outer ring size is smaller, so that the operator can smoothly install the electrical outer shell ring on the outer wall of the friction washer 34. After the electrical outer shell ring is installed, the support airbag ring 31 inflates under the action of gas to position the electrical outer shell ring. The support airbag ring 31 has a small overall thickness, which allows for a small adjustment of size while preventing large-scale shaking, thus improving the effect of supporting and positioning the electrical outer shell ring.
[0022] The top of the connecting air pipe 32 is equipped with an air supply pipe 33, and the connecting air pipe 32 and the air supply pipe 33 are connected by a rotary joint; the air supply pipe 33 is connected to the air supply pipe in the workshop. When the contour support ring 2 and the outer shell ring support frame plate 3 rotate, the connecting air pipe 32 and the air supply pipe 33 rotate relative to each other to avoid excessive torsion damage to the connecting air pipe 32 and the air supply pipe 33.
[0023] A friction washer 34, which plays a positioning role, is fixedly connected to the outer wall of the supporting airbag ring 31. By setting the friction washer 34, the friction between the electrical appliance housing ring and the supporting airbag ring 31 can be increased, thereby improving the positioning effect of the electrical appliance housing ring and preventing the electrical appliance housing ring from slipping off.
[0024] A support frame 51 is fixedly connected to the top of the grinding roller 5, and the support frame 51 is fixedly connected to the side wall of the lower support protective plate 1. By setting the support frame 51, the grinding roller 5 can be supported. The connecting rod between the support frame 51 and the lower support protective plate 1 is in a suspended state, so as to avoid obstructing the movement of the contour support ring 2 and the outer shell ring support frame plate 3.
[0025] The axes of the internal gear 4, the external gear 41, and the polishing roller 5 are on a straight line; the axis of the polishing roller 5 is located on the line connecting the internal gear 4 and the external gear 41, so that the polishing roller 5 can always contact the outer side of the electrical appliance housing ring while maintaining a vertical position, so as to polish the outer side of the electrical appliance housing ring.
[0026] The working principle and usage process of this utility model are as follows: The operator places the electrical appliance outer casing ring around the outer casing ring support frame plate 3, the support airbag ring 31, and the friction washer ring 34. Then, gas is supplied to the support airbag ring 31 through the connecting air pipe 32 and the air supply pipe 33. The expanded support airbag ring 31 compresses the inner wall of the electrical appliance outer casing ring to position it. Subsequently, the drive motor rotates the internal gear 4 and the external gear 41. The internal gear 4 and the external gear 41 limit the movement of the contour support ring 2 from the inside and outside, respectively, restricting the direction of movement of the contour support ring 2 and preventing it from swinging freely. The internal gear 4 and external gear 41, in conjunction with the internal drive gear 21 and external drive gear 22, drive the contour support ring 2 and the outer shell ring support frame plate 3 to circulate at the top of the lower support protective plate 1. While driving the contour support ring 2 and the outer shell ring support frame plate 3 to move, the grinding roller 5, whose axis is located on the connecting line of the internal gear 4 and external gear 41, rotates at high speed to automatically polish the electrical outer shell ring. After polishing is completed, the internal gear 4 and the grinding roller 5 stop running. After the gas in the support airbag ring 31 is discharged from the connecting air pipe 32 and the air supply pipe 33, the staff removes the polished electrical outer shell ring and replaces it with a new one.
