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

Abstract

An automatic crystal blank grinding and polishing system comprises: a first rotating support (2), upper hemisphere grinding positions (11, 12) and a polishing position (13), the first rotating support (2) being disposed with a machine head (21); a second rotating support (7), lower hemisphere grinding positions (61, 62) and a polishing position (63), the second rotating support (7) being disposed with a machine head (71); a loading position (41); an alignment position (42); an unloading position (43); at least one first transfer mechanism capable of picking up and releasing a fixture and capable of transferring the fixture among the loading position (41), the alignment position (42) and the machine head (21) on the first rotating support (2); and at least one second transfer mechanism capable of picking up and releasing a fixture and capable of transferring the fixture among the alignment position (42), the unloading position (43) and the machine head (71) on the second rotating support (7). Further disclosed is a grinding and polishing machine and an auxiliary machine used by the above system. The system is capable of implementing fully-automatic grinding and polishing processing of the inclined surfaces of the upper and lower hemispheres of a crystal blank to guarantee the processing quality of the grinding and polishing, and is also capable of fully using the advantages of the existing model, simplifying the complexity of the mechanism actions, and facilitating fabrication and maintenance.

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.
