Multifunctional superfinishing oilstone frame

Abstract

The invention discloses a multifunctional superfinishing oilstone frame. A bracket is arranged at the top of a base, and a lever is hinged at one side of the bracket; the bottom end of the oilstone frame is arranged at the top of the bracket; a pressing piece frame is hinged with the oilstone frame; the hinged position is positioned at one side, away from lever, of the oilstone frame; the top end of the pressing piece frame is corresponding to an oilstone arranged at the top end of the oilstone frame; a tension spring horizontally penetrates through through holes in the oilstone frame and the pressing piece frame; a sliding sleeve is arranged on a first guide sleeve in a sleeving manner; one end of the tension spring is fixed on the sliding sleeve; the other end of the tension spring is fixed on a second guide sleeve; an air cylinder is vertically fixed on the base; three end head positions of the lever are corresponding to the positions of a driving rod of the air cylinder, the sliding sleeve and the bottom end of the pressing piece frame. According to the multifunctional superfinishing oilstone frame, oilstone pressing force is not controlled by pneumatic pressure, the pressing air cylinder is only used for finishing pressing action, the pressing force is totally provided by the tension spring, and only system tensioning force of a spring tensioning mechanism is required to be adjusted, so that the pressing force of the oilstone is adjusted, and a pressure adjusting valve is not required.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment manufacturing, in particular to a multifunctional ultra-finishing oil stone stand. Background technique [0002] The traditional whetstone frame drives the pressure plate to compress the whetstone through the cylinder. The pressure of the cylinder must be adjusted through the pressure regulating valve to control the pressure of the whetstone. This pressure control method is very susceptible to the pressure fluctuation of the air source system. Moreover, many occasions require graded switching of pressure. For example, two different types of oil stone pressing force are required for coarse ultra-fine and fine ultra-fine. The traditional alkaloid frame does not have this function, and two pressure regulating valves must be used to realize the control of different pressing forces. switch. Therefore, this type of solution has high cost, cumbersome debugging, and unsatisfactory...

[0002] The traditional whetstone rack drives the pressing piece to compress the whetstone through the cylinder. The pressure of the cylinder must be adjusted through the pressure regulating valve to realize the control of the whetstone pressing force. This pressure control method is very susceptible to the pressure fluctuation of the air source system.

Moreover, many occasions require graded switching of pressure. For example, two different types of oil stone pressing force are required for coarse ultra-fine and fine ultra-fine. The traditional alkaloid frame does not have this function, and two pressure regulating valves must be used to realize the control of different pressing forces. to switch

Therefore, this type of solution has high cost, cumbersome debugging, and unsatisfactory reliability and stability.
