The invention relates to the technical field of
industrial machine tools, discloses an integrated
quartz tube
processing machine tool based on flexible traction, and aims at solving the problems that when a
centerless grinding machine supports a
quartz tube through line contact, due to the fact that the surface of a workpiece protrudes abnormally, limiting is poor, movement is prone to occurring, and the
processing quality is affected. A guide wheel and a
polishing wheel are arranged at the top; an arc-shaped opening is formed in the guide wheel, a flexible traction
assembly is arranged in the guide wheel, the guide wheel comprises a flexible conveying belt, two groups of symmetrical limiting assemblies are arranged in the guide wheel and are supported from the inner wall of the flexible conveying belt, so that a semi-wrapped
quartz tube workpiece is in surface contact, and a yielding
assembly is arranged at the end part of each limiting
assembly and comprises a telescopic inner column, an outer cylinder and a
proximity sensor; according to the
machine tool, the supporting area is enlarged through surface contact, the stability is improved through local yielding of the limiting assembly, targeted
polishing and automatic reset of protrusions are achieved in combination with the
proximity sensor, the
machining precision and smoothness of quartz tubes are improved, the
cracking risk and the
rejection rate are reduced, and the production efficiency is optimized.
