Mechanical and electrical integration spindle box and auxiliary structure of instrument lathe

Abstract

The technical scheme that a spindle box (13) is used for oil bath lubrication, a flange plate (15) is used for transition, and a motor shell (17) is arranged on the rear portion, the technical scheme that a hollow spindle (27) is mounted in a three-supporting-point manner through a front supporting bearing (2), a rear supporting bearing (10) and an auxiliary bearing (12), a wear-proof shaft sleeve (1), the front supporting bearing (2) and a first thrust bearing (3) are arranged at the front end of the hollow spindle (27), the middle segment of the spindle is in movable fit with a second thrust bearing (6) and is sequentially provided with a first piston (4), a second piston (5), the second thrust bearing (6), a sliding block sleeve (7), a thrust sliding block (8) and a spring (9), and the rear supporting bearing (10), a motor rotor (11) and the auxiliary bearing (12) are arranged at the rear end of the spindle, and the technical scheme that water cooling is carried out in the spindle box (13), the flange plate (15) and the motor shell (17) independently are mainly adopted. The beneficial effects that the space utilization rate and the number of use turns of an instrument lathe are increased, mechanical noise is lowered, safety is improved, and energy saving and emission reduction are achieved are achieved.

Description

technical field [0001] The invention belongs to the mechanical field and relates to an electromechanical integration structure of a spindle box of an instrument lathe. technical background [0002] At present, the clamping mechanism of the traditional instrument lathe is that the chuck at the front end is connected to the hollow tie rod, and the pull rod works in a way that the pull rod passes through the hollow main shaft and is connected with the tensioning mechanism at the rear end. Therefore, the transmission mode is basically belt drive or gear drive. Among them, the belt transmission has a simple structure, low cost, and small axial installation space, but the mechanical vibration of high-speed rotation is large, and more installation space is required for the motor to connect to the belt pulley; the gear transmission structure is compact and complicated, but the noise and energy consumption of the teeth are large.
