Abstract
The utility model discloses a double-shaft linkage low-speed large-torque direct drive hydrostatic headstock device, which comprises a headstock box body and is characterized in that in the headstock box body, a spindle is supported by front and rear liquid hydrostatic bearings; the rear part of the spindle is provided with a torque motor; and the tail end of the spindle is connected with an encoder. The utility model has the advantages that 1, a torque motor rotor is adopted to directly drive the spindle and no other connecting pieces are arranged between the motor rotor and the spindle so as to realize zero transmission and make the spindle have high transmission accuracy; and 2, the spindle is supported by the liquid hydrostatic bearings and has high rigidity. The spindle of the utility model has high transmission accuracy and high stress rigidity, so that not only the debugging time of double-shaft linkage of a machine tool is shortened, but also accuracy, response speed and processing stability of the double-shaft linkage of the machine tool are all superior to accuracy, response speed and processing stability of the conventional double-shaft linkage mechanism and the profile accuracy and the surface quality of a workpiece are improved.
Description
Technical field
The utility model belongs to machine tool component, is specifically related to a kind of 2-axis linkage low-speed big and directly drives the hydrostatic head rack device.
Background technology
Traditional 2-axis linkage headstock adopts servomotor, adds yielding coupling and connects drive shaft with the main shaft tail end, and main shaft bearing adopts paired duplex angular contact ball bearing.This headstock selects for use best yielding coupling also to have the possibility of minim gap.During this headstock low cruise, the main axis stiffness of servomotor moment of torsion and the supporting of main shaft ball bearing is all less, and the precision of processing is brought certain influence.Therefore, the precision of traditional 2-axis linkage headstock processing work is limited.
The utility model content
The purpose of this utility model is the defective that exists at prior art, provides a kind of 2-axis linkage low-speed big directly to drive the hydrostatic head rack device, to improve machining accuracy.
Realize that the technical scheme that the utility model purpose adopts is: the 2-axis linkage low-speed big directly drives the hydrostatic head rack device, comprise headstock casing, by forward and backward hydrodynamic journal liquid polymers supports main shaft, the rear portion of main shaft is provided with torque motor in the headstock casing, and the tail end of main shaft is connected with encoder.
Casing and rear box before described headstock casing is divided into, described forward and backward hydrodynamic journal liquid polymers are positioned at preceding casing, described torque motor is positioned at rear box, the stator of torque motor is fixed as one by stator installation sleeve and rear box, the rotor of torque motor is fixed as one by rotor positioning sleeve and main shaft, and described encoder is located on the rear box.
The beneficial effects of the utility model:
The one, adopt the direct drive shaft of torque motor rotor, there is not other connector between rotor and the main shaft, so be referred to as to have realized zero transmission, spindle drive precision height; The 2nd, main shaft adopts hydrodynamic journal liquid polymers supporting, main axis stiffness height.Because the utility model spindle drive precision height, stressed rigidity height, not only shortened the debug time of lathe 2-axis linkage, and the stability of the precision of lathe 2-axis linkage, response speed and processing all is better than traditional 2-axis linkage mechanism, improved the contour accuracy and the surface quality of workpiece.Therefore, the utility model is a kind of desirable 2-axis linkage headstock device that is applicable to the 2-axis linkage precision machine tool with low-speed big, high rigidity, high response, high stability.
Below be to further specifying that the utility model is made.
