The invention discloses an upper disc device for a double-faced precision grinding and polishing combined machine tool. The upper disc device comprises a power driven upper main shaft arranged on a rack, wherein the top end of the upper main shaft is provided with an oil pipe rotating joint and a water pipe rotating joint, the upper main shaft is internally provided with an oil passage and a water passage, the lower end of the upper main shaft is provided with a tray for fixing the upper disc through an universal moving part, and an axial annular groove is formed in the upper main shaft; a lock sleeve is sleeved on the upper main shaft between the annular groove and a joint bearing seat, a sealing oil cavity is formed between the lock sleeve and the upper main shaft, and the oil pipe rotating joint is communicated with the sealing oil cavity through the oil passage; a cooling water passage is arranged between the upper disc and the tray, and the water pipe rotating joint is communicated with the cooling water passage through the water passage. The upper disc device can realize quick linear repair and maintenance and circulating cooling of grinding and polishing equipment, so that the machining efficiency is greatly improved.
Description
technical field [0001] The invention belongs to double-sided grinding, grinding and polishing equipment, in particular to a loading device for double-sided precision grinding and grinding combined machine tools. Background technique [0002] The upper plate device of the existing double-sided grinding and grinding and polishing equipment is generally connected with the upper plate spindle through a universal mechanism to eliminate the influence of the parallelism error between the upper and lower plates and the thickness difference of the workpiece itself on the machining accuracy . In this way, the accuracy of the workpiece several grades higher than the accuracy of the equipment can be processed with lower equipment accuracy. The upper plate has a universal characteristic due to the universal mechanism, and its dressing can only be trimmed by a correction wheel, which cannot be trimmed in a straight line, making the trimming efficiency very low, and it is impossible to pe...
