Embodiment Construction

[0034] Below in conjunction with accompanying drawing, structure and working process of the present invention will be further described.

[0035] The two most important processes in the process of machining workpieces by grinding machines.

[0036] The pneumatic servo system requires its controlled object to accurately approach the target according to the target value specified in the controller. The target value can be the position of the cylinder or the magnitude of the output force of the cylinder. In the pneumatic servo system, a cylinder is required to stay at a certain position with certain precision requirements, and at the same time its output force must reach the set target value, and certain precision requirements are also required.

[0037] Such as figure 1 , figure 2 As shown, a pressure control method of a grinder pneumatic servo system, the grinder pneumatic servo system includes a control module, a pressure sampling module, a pressurization module, the contr...

Abstract

The invention discloses a pressure control method of a grinder air pressure servo system. A three-section pressurization and pressure reduction mode is adopted, so that pressurization is performed with larger steeping pressure to rapidly reach a pressure upper limit value at the beginning, then the pressurization is performed with smaller steeping pressure to reduce speed and reach a pressure lower limit value, and finally the pressurization is performed with the smallest steeping pressure to enable the speed to be constant slowly and reach a pressure set value. By means of the pressurization mode, the pressurization speed can be high, meanwhile the pressurization accuracy is high, uniformity is good, unbalance pressure of a workpiece is reduced, and the finished product rate is improved.

Description

technical field [0001] The invention belongs to the application field of electronic equipment, and in particular relates to a pressure control method of a grinder air pressure servo system. Background technique [0002] The surface grinder is a precision grinding and polishing equipment. The material to be ground and polished is placed on the grinding disc. The grinding disc rotates counterclockwise. The correction wheel drives the workpiece to rotate itself. The pressurized cylinder exerts pressure on the workpiece. To achieve the purpose of grinding and polishing. [0003] The grinding disc dressing mechanism adopts the hydraulic suspension guide rail to reciprocate back and forth, and the diamond shaving knife precisely trims the grinding surface of the grinding disc to obtain an ideal flat effect. [0004] The workpiece of the series grinding machine is pressurized by a cylinder, and the pressure is adjustable; [0005] The grinding machine adopts PLC program control s...
