Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a rolling and polishing machine for a counterweight sun gear train dental burr. Background Art

[0002] The polishing process in the production of dental burrs has always been a difficult problem for production enterprises. At present, the polishing of dental burrs mainly uses adding husks as abrasive materials in the polishing bin of a vibration polishing machine for polishing. This polishing process has the following deficiencies: First, the polishing efficiency is too low. It takes 3 - 5 hours to complete one polishing. In order to complete the polishing of all products, a large number of equipment need to be invested. Second, due to the extremely small size of the products (similar to the size of embroidery needles), it is difficult to separate the polished products from the abrasive materials (husks). If the separation is not thorough each time, it will cause material mixing when the abrasive materials are reused, and it is very difficult to distinguish the mixed materials. Third, one device cannot simultaneously polish products of two or more specifications, otherwise material mixing will occur. Fourth, the vibration noise is too large, polluting the environment. Therefore, it is very necessary to propose a polishing device that can simultaneously polish products of multiple specifications on one device, with high efficiency, convenient separation, low noise, and can avoid material mixing.

[0077] Generally speaking: As Figure 1 、 Figure 2 shown, a tumbling and polishing machine of the present utility model includes a frame 1, a tumbling and polishing box support 2, a tumbling and polishing box 3, a tumbling and polishing shaft 4, a tumbling and polishing gear 5, a moving gear 6, a moving gear shaft 7, a fixed gear 8, a fixed gear shaft 9, a runner 10, a retaining ring 11, a valve 12, a cover plate 13, and a motor 14. It is characterized in that: A fixed fixed gear shaft 9 is provided in the middle of the frame 1. A fixed fixed gear 8 and a runner 10 that can rotate around the fixed gear shaft 9 are provided in the middle of the fixed gear shaft 9. A motor 14 is provided at the bottom of the frame 1, and a cover plate 13 is provided at the upper part. A valve 12 is hinged at each end of the upper part of the frame 1.

[0078] The runner 10 is composed of a wheel body 102 and a wheel cover plate 101 to form a circular cavity runner. A group of evenly distributed and freely rotatable moving gear shafts 7 and a group of evenly distributed and freely rotatable tumbling and polishing shafts 4 are respectively provided on the runner 10 from the inside to the outside. A moving gear 6 is fixedly provided on each moving gear shaft 7, and a tumbling and polishing gear 5 is fixedly provided on each tumbling and polishing shaft 4.
