Z-axle drive system structure of gun turret milling machine

Abstract

The invention discloses a Z-axle drive system structure of a gun turret milling machine, which is applied to a machinery processing industry. The Z-axle drive system structure comprises a first screw, a nut base, a T-shaped axle, a second screw, a jacking screw, a servo motor, a synchronizing wheel, a ball screw, and a supporting bracket; the nut base is fixed on the ball screw through the first screw, and a nut of the ball screw is arranged in a vertical hole of the nut base; the front end of the T-shaped axle is fixed on a main axle sleeve of a milling machine through the second screw, and the other end of the T-shaped axle is arranged in the horizontal hole of the nut base and screwed by the jacking screw; the servo motor is installed at the left upper end of the supporting bracket, and the synchronizing wheel is installed on an axle neck of the servo motor; bearings are installed in bearing bases at left and right ends of the supporting bracket, and the ball screw is connected to the supporting bracket by crossing through the bearings. The Z-axle drive system structure is simple in structure, spare parts are greatly reduced; besides, the Z-axle drive system structure is low in cost, low in fault rate, high in intensity, good in function, long in service, simple in structure, and easy to operate.

Description

technical field [0001] The invention relates to a Z-axis transmission system structure of a turret milling machine in the mechanical processing industry, and is especially applied to the connection between a Z-coordinate lead screw and a milling spindle sleeve in the numerically controlled transformation of a turret milling machine. Background technique [0002] At present, in the mechanical processing industry, the turret milling machine can be widely used for machining planes, inclined surfaces at any angle, milling keyways, grooves, and can also be rotated, reamed, and bored. degrees, the ram can rotate 360 ​​degrees. The spindle speed range is large and the speed is high. The main shaft sleeve can be motorized and fed at a fixed distance, and is equipped with an overload protection device. Spindle sleeve, machine guide rail, and workbench are all hardened by high frequency, which is beautiful and practical. The vertical turret milling machine can be equipped with a mo...
