Cylindrical workpiece outer surface grinding device

Abstract

The invention relates to the field of grinding, in particular to a grinding device for the outer surface of a cylindrical workpiece. The device is supported by the fixture rotating part and the fixed fixture at both ends of the workpiece spindle respectively. The dressing wheel and the workpiece are coaxially installed on the workpiece spindle. The workpiece spindle drives the dressing wheel and the workpiece, and the workpiece spindle is driven to rotate by the fixture rotating part. The rotating part of the fixture and the fixed fixture are fixedly installed on the base of the rotating part of the fixture. The base of the rotating part of the fixture is connected to the reciprocating motor through the reciprocating motor shaft; the grinding wheel shaft is fixed on the grinding wheel seat, and one end of the grinding wheel shaft is connected to the grinding wheel drive motor The other end of the ring-shaped grinding wheel disc is installed, driven by the grinding wheel drive motor, and the grinding wheel shaft drives the annular grinding wheel disc at its front end to rotate. The present invention uses a cup-shaped grinding wheel disc and adopts a longitudinal grinding method to perform high-precision and high-efficiency finishing on the outer surface of a cylindrical workpiece.

Description

technical field [0001] The invention relates to the field of grinding, in particular to a grinding device for the outer surface of a cylindrical workpiece, which uses a longitudinal grinding method to finish the outer surface of a cylindrical workpiece through a cup-shaped grinding wheel disc with a circular grinding wheel surface . Background technique [0002] In the process of finishing the outer surface of cylindrical workpieces, grinding machines are generally used for grinding. The traditional method of grinding the outer surface of a cylindrical workpiece is: while rotating and supporting the workpiece, attach a high-speed rotating emery wheel to the cylindrical outer surface of the workpiece for grinding. However, the outer surface of the workpiece ground by this method must also take into account the deformation caused by the processing heat and force generated during grinding, as well as the deflection of the grinding wheel disc and the workpiece support; The out...

AI Technical Summary

Problems solved by technology

However, the outer surface of the workpiece ground by this method must also take into account the deformation caused by the processing heat and force generated during grinding, as well as the deflection of the grinding wheel disc and the workpiece support; The outer surface of the outer surface faces the width direction for finishing with a straight section. Due to the influence of the above-mentioned processing heat and force, after the processed workpiece returns to normal temperature, the central part of the outer surface in the width direction will also be radially recessed. , the tendency to form a concave shape

Therefore, if the workpiece with a concave shape is assembled into the device as a part, it will cause imbalance in high-speed rotation, and it is easy to wear and slip, and the product life cycle will be shortened, and the use of the device will be affected.
