The preceding liquid kickboard, middle liquid kickboard and rear liquid kickboard are respectively arranged with fuel feed hole and and oil inlet on one side end face of slide carriage
The high-voltage oil cavity of hole connection；
The slide carriage is vertically arranged between two middle liquid kickboards, and respectively with preceding liquid kickboard, middle liquid kickboard and rear liquid kickboard it
Between be equipped with oil clearance, make slide carriage can free movement in the vertical direction；
The oil box is installed on the underface of preceding liquid kickboard, middle liquid kickboard and rear liquid kickboard；
The friction-free air cylinder is installed on the top of pedestal, and the axis of friction-free air cylinder is parallel with the direction of motion of slide carriage；
The pneuma-lock device is fixed on the top of pedestal by locking connecting bracket, and is divided in the two sides of friction-free air cylinder；
The locking post is fixed on the upper surface of slide carriage, and passes through from pneuma-lock device center.
Compared with the prior art, the present invention has the advantage that
The present invention forms high pressure oil film using fluid pressure principle, makes slide carriage and preceding liquid kickboard, middle liquid kickboard, between rear liquid kickboard
Do not generate equipped with there are gap, when slide carriage moves with liquid kickboard frictional force (coefficient of friction of hydrodynamic lubrication is minimum, it is negligible not
Meter), to carry out that creeping phenomenon will not be generated during low-speed motion without friction, vibrationless smooth movement.In addition, high
Pressure oil film has Panel-corrected Model, can compensate for the mismachining tolerance of piece surface, improves equipment precision.
