An automatic grinding and polishing system for crystal blanks and its grinding and polishing machine

Abstract

The invention discloses a crystal blank automatic grinding and polishing system and a crystal blank automatic grinding and polishing machine. The crystal blank automatic grinding and polishing system and the crystal blank automatic grinding and polishing machine comprise a grinding and polishing rack. A roller grinding tool is installed on the grinding and polishing rack, the roller grinding tool is driven by a grinding tool motor installed on the grinding and polishing rack to rotate around a horizontal rotating shaft, a plurality of grinding and polishing mechanisms are installed around the roller grinding tool in an up-and-down mode, the length stretching direction of clamps installed in the grinding and polishing mechanisms is parallel to the direction of the rotating shaft of the roller grinding tool, the grinding and polishing mechanisms are installed on a rotating base, the rotating base and the roller grinding tool are coaxially and rotationally arranged, and the rotating base is driven by a rotating base driving device installed on the grinding and polishing rack to rotate. According to the technical scheme, compared with the prior art, repeated grinding and polishing machining can be finished on one grinding and polishing station, therefore, the device utilization ratio and production efficiency are fully improved, manufacturing cost of a machine table is reduced, and the size of the machine table is reduced.

Description

technical field [0001] The invention belongs to the field of grinding and polishing processing of crystal products, and relates to an automatic grinding and polishing system for crystal blanks for automatic grinding and polishing processing of crystal blanks, in particular to a grinding and polishing machine therein. Background technique [0002] In the prior art, the automatic grinding and polishing system (grinding and polishing machine) of crystal blanks includes: a feeding station, which is provided with a feeding mechanism capable of fixing the crystal blanks on the fixture; The upper hemisphere grinding station for grinding the hemisphere and at least one upper hemisphere polishing station for polishing the upper hemisphere of the crystal blank; the docking station is provided with the ability to transfer and fix the crystal blank from a fixture to On the other fixture, a docking mechanism capable of exchanging the positions of the two fixtures; at least one lower hemi...

Problems solved by technology

[0007] However, the above-mentioned structure is that the fixture seats on each station are arranged parallel to the left and right along the length direction of the fixture (especially the grinding and polishing station). Lift the fixture on the fixture seat of the station, and then step over the fixture seat mechanism on the corresponding station, and then send it down and place it on the fixture seat of another station. Such a left-right transfer mechanism is complicated in structure, cumbersome and easy Faulty and costly

In its docking mechanism, the first front and rear transfer mechanism needs to transfer the belt clamp from the docking bracket to the conversion bracket, and then wait for the conversion bracket to rotate 180 ° after the upper and lower positions are reversed, and then the first front and rear transfer mechanism will transfer the material on the conversion bracket The jig with glue is sent to the docking bracket. During this process, the first front and rear transfer mechanism reciprocates the jig, and the docking bracket can only be in a waiting state, which increases the waiting time of the machine, so further improvements are needed to increase production efficiency.

Moreover, only one grinding and polishing process can be completed on one grinding and polishing station. When the grinding and polishing surface of the crystal blank needs to be polished and polished multiple times, it is necessary to arrange multiple grinding and polishing machines, which leads to low equipment utilization and space occupation. Huge and frequently moving fixtures between multiple stations at the same time, which increases the cost of equipment manufacturing and reduces the processing efficiency of the entire automatic cycle
