Cylindrical workpiece polishing machine

Abstract

The invention relates to a cylindrical workpiece polishing machine which comprises a support, a reciprocating polishing device and a cylindrical workpiece driving device. The cylindrical workpiece driving device can drive a cylindrical workpiece installed on the polishing machine to rotate, and can adapt to cylindrical workpieces with different lengths. The reciprocating polishing device can drivea polishing belt tensioning device to move left and right to comprehensively polish the cylindrical workpiece, a push-pull arm locking device on the polishing belt tensioning device can lock a polishing belt at a working position, a sliding bar between a supporting block and a lower sliding rod on the polishing belt tensioning device can provide downward elastic force to press down the lower sliding rod when two push-pull arms slide a clamping plate upwards to be separated from a lower sliding shaft, therefore, a belt wheel at the lower position is driven to press down, and the phenomenon that a belt on the belt wheel is loosened and falls down when the two push-pull arms move upwards is avoided.

Description

technical field [0001] The invention relates to the technical field of cylinder polishing, in particular to a cylindrical workpiece polishing machine. Background technique [0002] The polishing of cylindrical workpieces occupies a large proportion in the polishing field. At present, manual polishing or semi-automatic polishing is mostly used for cylindrical workpieces. Manual polishing is performed by hand-held polishing machines, or directly by holding polishing sandpaper by hand, which is labor-intensive. , the efficiency is not high, most of the semi-automatic polishing is to fix and rotate the cylindrical workpiece, then fix the polishing device to one side of the cylindrical workpiece, and polish the polishing belt in contact with the cylindrical surface, but when the cylindrical workpiece is polished, manual work is required Only by moving the workpiece left and right can the complete polishing of the cylindrical workpiece be realized, which increases the labor intens...

[0002] The polishing of cylindrical workpieces occupies a large proportion in the polishing field. At present, manual polishing or semi-automatic polishing is mostly used for cylindrical workpieces. Manual polishing is performed by hand-held polishing machines, or directly by holding polishing sandpaper by hand, which is labor-intensive. , the efficiency is not high, most of the semi-automatic polishing is to fix and rotate the cylindrical workpiece, then fix the polishing device to one side of the cylindrical workpiece, and polish the polishing belt in contact with the cylindrical surface, but when the cylindrical workpiece is polished, manual work is required Only by moving the workpiece left and right can the complete polishing of the cylindrical workpiece be realized, which increases the labor intensity of the workers, and manual movement cannot guarantee the accuracy, which affects the polishing quality of the workpiece; moreover, it is difficult to rotate the cylindrical workpiece when manually operating the cylindrical workpiece , so the polishing belt is troublesome to polish the entire side of the cylindrical workpiece, and the efficiency is not high, and the relatively long cylindrical workpiece cannot be clamped and fixed on the polishing machine, which affects the working efficiency of the polishing equipment
