Problems solved by technology

When the existing honing machine switches between rough grinding and fine grinding, it is necessary to manually control the gearbox of the honing machine to change the gear ratio, so as to practice the change of the speed of the honing head of the honing machine. The control process requires manual participation, which affects Processing efficiency and processing accuracy

Abstract

A honing head driving mechanism of a honing machine comprises a transmission box, a motor, two driving conical wheels, two driven conical wheels and a steel band. Along with grinding, conducted by a honing stick on a honing head, on a workpiece, the roughness of the surface of the workpiece is greatly lowered, the friction force between the honing head and the surface of the workpiece is reduced, a driven conical wheel driving mechanism drives the two driven conical wheels to be mutually separated and move outwards, an extension spring I drives the two driving conical wheels to be mutually close to each other and move inwards, the length of the portion, wrapped around the two driving conical wheels, of the steel band is larger than the length of the portion, wrapped around the two driven conical wheels, of the steel band, transmission ratio stepless change is achieved, the rotating speed of a driven shaft is larger than that of a main shaft, so that the rotating speed of the honing head is greatly improved, and the honing head can meet the rotating speed requirement when conducting the workpiece accurately. In the whole speed change process, stepless speed adjustment is achieved along with change of the roughness of the workpiece, so that manual operation is not needed; and in this way, the honing efficiency is improved, and the honing quality of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to the field of honing machines, in particular to a driving mechanism for a grinding head of a honing machine. Background technique [0002] In industrial production, a honing machine is a grinding machine that uses a honing head to honed the surface of a workpiece. It is mainly used for honing the holes of workpieces in manufacturing industries such as automobiles, tractors, hydraulic parts, bearings, and aviation. Honing machines are precision manufacturing equipment. When the honing machine grinds the hole of the workpiece, it is divided into two steps: rough grinding and fine grinding. Fine grinding, during fine grinding, the abrasive bar of the honing head has a small amount of knife cutting, but the spindle speed needs to be increased to achieve the effect of fine grinding. When the existing honing machine switches between rough grinding and fine grinding, it is necessary to manually control the gearbox of the honing machi...
