Crystal blank automatic grinding and polishing system, grinding and polishing machine and auxiliary machine thereof

Abstract

The invention relates to a crystal blank automatic grinding and polishing system. The system comprises a first rotating stand, a second rotating stand, a loading station, a butting station, an unloading station, at least one first transfer mechanism and at least one second transfer mechanism, wherein the first rotating stand is provided with an upper semi-sphere grinding station and a polishing station, and a nose is arranged on the first rotating stand; the second rotating stand is provided with a lower semi-sphere grinding station and a polishing station, and a nose is arranged on the second rotating stand; the first transfer mechanism can pick up and release a clamp, and can transfer the clamp among the feeding station, the butting station and the nose on the first rotating stand; and the second transfer mechanism can pick up and release the clamp, and can transfer the clamp among the butting station, the discharge station and the nose on the second rotating stand. The invention also discloses a grinding and polishing machine and an auxiliary machine used by the system. By utilizing the technical scheme, the upper and the lower semi-sphere inclined planes of a crystal blank canbe automatically ground and polished to ensure the quality of grinding and polishing processing, and the advantages of the machine models can be sufficiently utilized to simplify the complex degree of the mechanism action. The crystal blank automatic grinding and polishing system, the polishing machine and the auxiliary machine are easy to manufacture and maintain.

Description

technical field [0001] The invention relates to the field of grinding and polishing of crystal products, in particular to an automatic grinding and polishing system for crystal blanks for automatic grinding and polishing of crystal blanks, and a multi-station grinding and polishing machine and auxiliary machinery involved in the system. Background technique [0002] Existing multi-station crystal bevel grinding and polishing machines all adopt a plurality of heads fixed with rhinestone fixtures to rotate for multi-station processing. For example, the patent document whose publication number is CN201179615Y discloses a kind of automatic loading and unloading rhinestone bevel grinding and polishing. The machine includes a frame, on which two rotating frames are arranged side by side, and a machine head is arranged on each of the four sides of the rotating frame, which constitutes seven stations, which are the feeding station, the front hemisphere rough grinding station, and the...

Problems solved by technology

During the actual implementation of this technical solution, the inventor found the following problems: First, at the docking station, the two docking fixtures are respectively located on the two rotating frames, which requires high manufacturing precision and is difficult Ensure the docking accuracy; secondly, the machine is large in size, which is difficult to manufacture and transport; thirdly, the space for the docking station, loading station, and unloading station is limited, and the complex structure design and cumbersome actions affect the processing efficiency

However, because the fixtures are circulated on the fixture seats of each processing station, for a crystal blank on a specific fixture, in order to ensure the consistency of its processing at each station, it is necessary to ensure that the fixtures are compatible with each work station. The matching consistency of the fixture seat on the position (including the consistency of the grinding and polishing angle, the turning angle, etc.), and once there is an error, the error accumulation and amplification effect will appear, which is especially important for the grinding and polishing station. If If there is an inconsistency between front and back matching and positioning, the subsequent polishing process will not polish the inclined surface processed by the previous grinding process, resulting in a greatly reduced polishing effect. Accurate positioning on the surface is very important, but for the existing technology and mechanism, it is still quite difficult to achieve the consistency of the fixture and the fixture seat of each station and the accurate positioning of the machine automatically, and there are complicated and cumbersome mechanism actions, which are easy to Failures, high maintenance costs, etc.

Similarly, the use of a complete machine structure also has problems such as large volume and difficulty in transportation and manufacturing.
