Abstract
The invention relates to a driving and self-locking device for a tailstock of a heavy-duty machine tool. On the basis of the structure of a driving device for the tailstock of the heavy-duty machine tool disclosed in the existing patent 201010287970.6, an electromagnetic clutch brake is installed at one end of a motor. Thus, braking of a whole transmission system is achieved, relative displacement between parts of the transmission system will not be caused even if gap exists between the parts of the transmission system, and thus the tailstock can be self-locked. The driving and self-locking device has the advantage of being reliable in locking.
Description
Technical field
The present invention relates to the lathe that machining is used, be specifically related to heavy machine tool tailstock and drive and self-locking device, belong to machine tool technology field.
Background technology
As everyone knows, the tailstock of heavy machine tool due to quality and volume all larger, so, be difficult for realizing easily the movement of artificial and mechanical system, to this, Chinese invention patent 201010287970.6 discloses a kind of heavy machine tool tailstock driving device, this technology has compact conformation, transmission accuracy is higher, and can realize the object of the motor-driven adjusting of tail stock for machine tool, but, the self-locking of this heavy machine tool tailstock driving device is to rely on the worm screw of mutual transmission and the latching characteristics of snail master bar self to reach self-locking object, because worm screw and snail master bar are in processing and manufacturing, and inevitably can there is error in the process of assembling, so, will inevitably there is a certain amount of gap in worm screw and the snail master bar of transmission of cooperatively interacting, in addition, worm screw and snail master bar certainly exist wearing and tearing in the course of the work, further strengthened the fit clearance between worm screw and snail master bar, the existence in this gap, will inevitably cause between worm screw and snail master bar and cannot reach better self-locking state, thereby it is fixing reliably to make tailstock can not realize on lathe bed, easily cause processed workpiece have mass defect or scrap, even can cause device security accident.
Summary of the invention
The object of the invention is to: for the existing defect of above-mentioned prior art, the present invention proposes a kind of corrective measure for above-mentioned technological deficiency, that is: a kind of heavy machine tool tailstock of the present invention drives and self-locking device.
The present invention realizes the technical scheme that above-mentioned purpose adopts: do not changing on the structure of prior art and the basis of transmission system, in the end of motor, install and fix an electric clutch-brake, braking original paper and the motor shaft of described electric clutch-brake are connected and fixed, described electric clutch-brake is normally closed type electric clutch-brake, that is: under outage condition, electric clutch-brake is in on-position, and under energising situation, electric clutch-brake is braking disarm state.
Beneficial effect: the present invention is owing to adopting after said method, after tailstock adjusting puts in place, motor is in power-off, and electric clutch-brake is power-off simultaneously also, now, electric clutch-brake is in on-position, thereby realize the braking of whole transmission system, even if there is gap between transmission system, also can not cause and between transmission system, have mutual displacement, thereby realize the self-locking of tailstock, there is reliable lock.
