An automatic pressurization method for grinding equipment

Abstract

Disclosed is an automatic pressurizing method of grinding equipment. The automatic pressurizing method includes the steps that 1), when in idle load, weight of a grinding table is transferred onto lower springs through a lower spring pressing plate, at this moment, upper springs are free of pressure, and elastic force of the lower springs is equivalent to a self-weight load value of the grinding table; 2), the elastic force controlling the lower springs is gradually reduced, the amount of reduction is load pressure, and at the moment, the upper springs are free of the pressure; 3), when the elastic force of the lower springs is reduced to zero and the load pressure is equivalent to the self-weight load of the grinding table, both the upper springs and the lower springs are free of the pressure; 4), when the elastic force of the lower springs is zero and the pressure controlling the lower springs is gradually increased from zero, the lower springs are free of the pressure, and the load pressure applied as a whole is equivalent to the pressure of the self-weight value plus the upper springs, so that continuous adjustment of the load pressure from being smaller than the self-weight load of the grinding table to larger than self-weight load of the grinding table is realized. Since the load being smaller than self weight of the grinding table and larger than the self-weight load of the grinding table is exerted simultaneously, the automatic pressurizing method is high in control precision, good in stability and low in cost.

Description

technical field [0001] The invention relates to an automatic pressurization method for grinding equipment, especially for precision vertical ball grinding machine tools or flat (single-sided, double-sided) grinding / polishing machine tools. Background technique [0002] The precise controllability and stability of the processing load of the precision vertical ball grinding machine and the surface grinding / polishing machine is a key factor affecting the final quality of the processed product. It has a direct impact on the surface quality and material removal rate of the product. Therefore, the pressurizing device is a key component of precision machine tools. [0003] At present, most of the pressurization systems of domestic precision sphere grinding machine tools and plane grinding / polishing machine tools are driven by a cylinder or a hydraulic cylinder to realize pressure loading by a set of spring pressurization mechanisms. This spring pressurization mechanism is characte...
