In the actual workpiece grinding process, after the distance between the upper grinding wheel and the lower grinding wheel is adjusted, the lower grinding driving device connected with the lower grinding wheel and the upper grinding driving device connected with the upper grinding wheel do not adjust the distance in the vertical direction in the working process; if the abrasion of the grinding wheel and the thickness of the workpiece are changed, the upper grinding driving device and the lower grinding driving device are driven to do feeding motion through the actions of the servo motor II, the servo motor III and the screw rod to adjust the distance between the upper grinding wheel and the lower grinding wheel and the workpiece, and the transmission of the upper grinding wheel and the lower grinding wheel is not affected due to the action of the width in the adjustment process.
The motor and the servo motor can be independently controlled, so that a workpiece can be kept in a static state or a rotating state in the grinding process, and particularly, adjustment is carried out according to actual needs.
The above is merely a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that do not undergo the inventive work should be covered in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
