High-pressure nitrogen balance weight balance cylinder system for workpiece machining

Abstract

The invention discloses a high-pressure nitrogen balance weight balance cylinder system for workpiece machining. The high-pressure nitrogen balance weight balance cylinder system comprises a nitrogenbalance component, a controller and a nitrogen container. One side of a fixed plate is fixedly connected with a first sliding rail, a gear rack is arranged at the top of the first sliding rail, one side of the first sliding block is fixedly connected with a servo motor, and an output shaft of the servo motor is fixedly connected with one end of a rotary shaft arranged on the hollow portion of thefirst sliding block. The other end of the rotary shaft is rotationally connected with one side of the inner wall of the first sliding block, the middle of the rotary shaft is connected with a gear through a connecting key, the bottom of the first sliding block is fixedly connected with a spindle box, and one side of the spindle box is connected with an air cylinder piston rod, stretching outwards,on an air cylinder body through a connecting block. According to the high-pressure nitrogen balance weight balance cylinder system, the problems that a traditional air balance weight balance cylindersystem does not have the advantages of being sensitive in response during vertical movement of an axis Z, reducing forward and reverse buffering, effectively improving the surface smoothness of workpiece machining and being capable of increasing the movement speed are solved.

Description

technical field [0001] The invention relates to the technical field of gas balance cylinder systems, in particular to a high-pressure nitrogen balance cylinder system for workpiece processing. Background technique [0002] A machine tool such as a machining center is provided with a main shaft and a main shaft assembly having an electric motor for rotationally driving the main shaft, and the main shaft assembly is supported and driven up and down by an elevating drive mechanism. This lifting drive mechanism is usually a ball screw, a ball nut screwed with the ball screw and connected to the main shaft assembly, and an electric motor, and the main shaft assembly and the ball nut are driven up and down together by the electric motor rotating the ball screw. . [0003] Since the lifting drive mechanism is mainly driven by the motor, the load of the lifting drive mechanism is very large, which may reduce the position accuracy of the spindle assembly in the vertical direction, a...
