A kind of self-adjusting static pressured plane guide rail

A self-adjusting static pressured plane guide rail consists of a base, a slider provided on the base and an upper pressing plate corresponding to the shoulders on both sides of the slider;

• wherein:
• the outer edge of each upper pressing plate contacts the base to form a fulcrum and the inner edge of upper pressing plate acts as the force portion, a upper pressing block is set between the force portion and the shoulder of the slider, a metal wire is set between the top surface of the upper pressing block and the bottom surface of the force portion of upper pressing plate along the sliding direction of the slider;
• the upper pressing plate is provided with a pre-tightening bolt to connect the base in a fixed way, the pre-tightening bolt is located between the fulcrum and force portion of the upper pressing plate;
• pressure oil is fed between the bottom surface of upper pressing block and top surface of slider shoulder to form a rigid oil film layer, the pressure oil is fed between the bottom surface of the slider and the base to form a rigid oil film layer.
