Description

Technical Field

[0001] The utility model relates to the technical field of bar polishing, in particular to a multiple polishing device for bar processing surfaces. Background Art

[0002] The shapes of materials used in processing and production are various, including rod-shaped materials. When faced with rods with rough surfaces, special polishing equipment is needed to perform multiple polishing processes on their surfaces to make them smooth for subsequent use.

[0003] Nowadays, devices for polishing the surface of rods mostly use two rotatable polishing rollers to polish the transmitted rods. However, the distance between the two polishing rollers is generally fixed and cannot be properly adjusted. They cannot be flexibly adjusted together with other equipment in the device mechanism, so that the diameter of the polished rods is fixed and cannot be adapted to the polishing of rods of various diameters. Equipment of various specifications is required to meet the needs of polishing rods of different diameters, so the versatility of the device is low, the processing cost is high, and the production efficiency is low.

[0004] Therefore, with regard to the above-mentioned existing device for polishing the surface of rods, the distance between the two polishing rollers used for processing is fixed and cannot be properly adjusted, and the grinding distance cannot be flexibly changed, so that only rods of a single diameter can be polished. It is necessary to prepare equipment of various specifications to adapt to the polishing of rods of different diameters. The versatility is low, the processing cost is high, the production efficiency is low, and it cannot meet the use requirements. A multiple polishing device for the surface of rods can be designed. By setting a mechanism that can stably move the two polishing rollers relative to each other and control the two polishing rollers to a certain distance position, it can be adapted to polish rods of different diameters, thereby improving the versatility of the device, reducing processing costs, and improving work efficiency to meet people's production and use needs.
