Frictionless quick-response balance system

Abstract

The invention discloses a frictionless quick-response balance system, comprising a cylinder body, a piston shaft sleeve, a lower end cover shaft sleeve, a steel wire rope and a piston rod; the piston rod is inserted into a hollow cavity of the cylinder body; the piston shaft sleeve is installed outside the upper end part of the piston rod in a sleeving manner; the outside of the piston shaft sleeve contacts the inside wall of the cylinder body; an upper end cover and a lower end cover are respectively arranged at the upper and lower end parts of the cylinder body; the lower end cover shaft sleeve is installed on the inside wall of the lower end cover in the sleeving manner; one end of the piston rod is arranged in the hollow cavity of the cylinder body, and the other end of the piston rod passes through the lower end cover shaft sleeve and stretches out from the hollow cavity of the cylinder body; the steel wire rope passes through the hollow cavity of the piston rod; the top part of the steel wire rope is fixed in a groove in the upper part of the piston rod by a nut; the lower part of the steel wire rope passes through the hollow cavity of the piston rod, is exposed outside the piston rod and is used for lifting a load. According to the frictionless quick-response balance system disclosed by the invention, the load can be moved up and down frictionlessly, and the influence on balance of an entire lifting device and a machine tool Y axis due to an eccentric force can be eliminated; therefore, the stability and the reliability of the work are improved.

Description

technical field [0001] The invention is a frictionless quick response balancing system, in particular a lifting balancing device used as a Y-axis up and down movement of an ultra-precision machining machine tool, which belongs to the innovative technology of a frictionless quick response balancing system. Background technique [0002] The existing frictionless quick-response balance system generally uses a single ventilation mechanism to complete the tasks of gas suspension support and lifting load at the same time. The air flow of the orifice in the suspension support part is insufficient, resulting in insufficient thickness of the air film, which affects the effect of air suspension. In addition, the existing frictionless quick-response balancing system adopts a structure in which the load is directly lifted by the piston rod. When the movement axis of the movable component of the frictionless quick-response balancing device is eccentric to the axis of the Y-axis moving u...

[0002] The existing frictionless quick-response balance system generally uses a single ventilation mechanism to complete the tasks of gas suspension support and lifting load at the same time. The air flow of the orifice in the suspension support part is insufficient, resulting in insufficient thickness of the air film, which affects the effect of air suspension

In addition, the existing frictionless quick-response balancing system adopts a structure in which the load is directly lifted by the piston rod. When the movement axis of the movable component of the frictionless quick-response balancing device is eccentric to the axis of the Y-axis moving up and down of the ultra-precision machine tool, the eccentricity cannot be eliminated. The impact of the force on the balance of the entire lifting device and the Y-axis of the machine tool, as well as the possibility of damaging the lifting device and the machine tool, will affect the stability and reliability of the entire machine tool.
