Vertical centerless grinder

Abstract

The invention relates to a vertical type centerless grinding machine. A feeding frame extends to the left and right and supported by a plurality of rows of racks on the lower side, two rollers are arranged above the feeding frame, each roller drives a plurality of rolling wheels, bottoms of rolling wheels are moveably connected with the feeding frame, rollers drives universal shafts of rolling wheels to rotate rolling wheels, an upright column is located in the middle of the feeding frame and extends upwards, a servo motor is arranged at the top of the upright column, a grinding wheel support is installed on the upright column, a grinding wheel transmission motor is installed on the grinding wheel support, the grinding wheel support can move up and down on the upright column through the servo motor, a grinding wheel and the grinding wheel transmission motor are located at two ends of the grinding wheel support respectively, the grinding wheel transmission motor drives the grinding wheel to rotate through a belt, a grinding wheel adjusting device which is used for adjusting the position of the grinding wheel is arranged above the grinding wheel, the grinding wheel is located above rolling wheels, two rolling wheel transmission motors are installed on two sides of the rack at the outmost end respectively, and each rolling wheel transmission motor drives one roller to rotate. According to the vertical type centerless grinding machine, the grinding wheel is driven by the servo motor to move up and down, so that the automatic movement is achieved.

Description

technical field [0001] The invention relates to a mechanical grinder, in particular to a vertical centerless grinder. Background technique [0002] At present, in the grinding machine for precise grinding of steel pipes, the grinding wheel of the grinding machine is generally installed on the side, the grinding wheel cannot automatically move up and down, and the adjustment is complicated, the grinding efficiency is low, and the grinding accuracy is not good. Especially for workpieces with large outer diameters and long lengths, centerless grinding machines cannot achieve large and long processing conditions due to the limitations of the body and the distance between advance and retreat, while cylindrical grinders cannot achieve large and long processing conditions due to the limitation of the center thimble distance. The grinding efficiency of the circular grinder is low. Contents of the invention [0003] The purpose of the present invention is to provide an automatic v...
