Stepless grinding and polishing device

Abstract

The invention discloses a stepless grinding and polishing device. The stepless grinding and polishing device comprises a main shaft and a revolution plate connected to the lower section of the main shaft. A plurality of grinding head installation positions are arranged on the revolution plate. A stepless grinding head is arranged in each grinding head installation position. Each stepless grinding head comprises a grinding head fixing base with a shaking space. Grinding blocks are connected with the lower ends of grinding wheel shafts. The middle sections of the grinding wheel shafts are provided with spherical motion pairs, wherein the spherical motion pairs are located in the shaking spaces, and gaps are reserved between the spherical motion pairs and the peripheral walls of the shaking spaces. The upper sections of the grinding wheel shafts are connected with the grinding head fixing bases in an elastic mode. In the working process, the grinding method that revolution and free rotation are integrated and the grinding blocks can rotate in all directions in the free rotation process is achieved for the stepless grinding heads, and therefore the surface of a plate to be machined can have a certain profiling function, the surface of the plate can not be easily pressed and damaged, the rough grinding and polishing effects are good, and work efficiency is high. The stepless grinding and polishing device is suitable for machining surfaces of building ceramics, stone materials and decorative plates.

Description

technical field [0001] The invention relates to an abrasive tool used for rough grinding and polishing of building ceramics, stone materials and decorative plates. Background technique [0002] Now in the industries of architectural ceramics, stone, decorative plate processing, etc., the rough grinding machine with the saddle frame mounted drum structure is mainly used to roughly grind the plate and the polishing grinding head of the swinging foot type is used for polishing. When working, the working method of the coarse grinder with the drum structure is that the abrasive tool is in line contact with the plate, and there are striped grinding marks on the processed surface, and the surface roughness of the plate is relatively large; and the abrasive tool is easily affected by the reverse grinding deformation on the surface of the plate processing quality. The abrasive tool of the swing-foot polishing machine is also in linear contact with the surface of the plate. When poli...

Problems solved by technology

When working, the working method of the coarse grinder with the drum structure is that the abrasive tool is in line contact with the plate, and there are striped grinding marks on the processed surface, and the surface roughness of the plate is relatively large; and the abrasive tool is easily affected by the reverse grinding deformation on the surface of the plate processing quality

The abrasive tool of the swing-foot polishing machine is also a linear contact between the abrasive tool and the plate surface. When polishing, the surface of the plate is prone to dragging marks and uneven polishing gloss.

At the same time, due to the rough surface and poor surface quality of the plate after processing by the previous rough grinder, many sets of polishing grinding heads are needed for polishing, which increases the energy consumption of processing. The swing foot polishing mainly uses magnesium oxide combined with silicon carbide grinding blocks. Grinding blocks mainly use bitter calipers as the matrix, which has great pollution to the environment, especially water resources. At the same time, the grinding blocks are made of silicon carbide, so the work efficiency is low.

Moreover, due to the linear contact processing of the drum-type coarse grinder and the swing-foot polisher, it is easy to cause brittle plates (such as ceramic tiles) to break and explode, and there is a large potential safety hazard
