Auxiliary device for grinding and polishing the arc surface of the workpiece on the plane grinding and polishing machine

Abstract

The invention discloses an auxiliary device for grinding and polishing an arc surface of a workpiece on a plane grinding and polishing machine, and belongs to the field of grinding and polishing of the arc surface of the workpiece. The auxiliary device comprises a support plate, an L-shaped support, a support, a a shaft sleeve, a connecting plate, a motor, an eccentric wheel, a connecting rod, aneccentric arm, a shaft and a workpiece mounting module, wherein the support plate is detachably fixed to a workbench of the plane grinding and polishing machine, one side surface of the L-shaped support is in pivot connection with the support plate, the support is fixed to the other side surface of the L-shaped support, the shaft sleeve is in pivot connection with the support, the connecting plateis vertically arranged at the upper end of the shaft sleeve, the motor is fixedly connected to the connecting plate, the eccentric wheel is fixedly connected to an output shaft of the motor, one endof the connecting rod is in pivot connection with the eccentric wheel, one end of the eccentric arm is in pivot connection with the other end of the connecting rod, one end of the shaft is fixed to the other end of the eccentric arm, and the workpiece mounting module is installed at the other end of the shaft. According to the auxiliary device, parameters such as the position, the height, the workpiece swinging angle, the workpiece swinging speed, the load force borne by the workpiece and the installation of different workpieces can be changed, so that grinding and polishing of a cylindrical surface or a conical surface of the workpiece are realized.

Description

technical field [0001] The invention relates to the field of grinding and polishing of the arc surface of a workpiece, and the invention is an auxiliary device for grinding and polishing the arc surface of a workpiece on a plane grinding and polishing machine. Background technique [0002] At present, the main types of grinders are plane grinders and rotary shaft grinders. The plane grinder is used to grind planes, and the rotary shaft grinder is used to grind inner and outer cylindrical surfaces. The workpieces are ground and polished with a high-precision plane grinder, but the current plane grinder can only be used for grinding and polishing the plane. If there is an arc-shaped cylindrical surface or an arc-shaped conical surface in the workpiece that needs to be ground and polished, then You can only choose a rotary shaft grinder, which is not only troublesome and difficult to operate, but also requires special fixtures.
