In order to achieve the above objectives, the technical solution adopted in the utility model is as follows：
A kind of numerical control external cylindrical grinding machine tailstock assembly, key are：Including mounting base, installed respectively in the mounting base
There are sleeve, piston and rotation axis, is installed with tail spindle in the side of the sleeve, and the set is stretched out in the outer end of the tail spindle
Cylinder formation is top, and spring is installed in the other side of the sleeve, which is connected between the inner wall and nut of the sleeve,
The nut is fixedly connected with the inner wall of mounting base, and lever is arranged in the rotation axis, and being arranged side by side on the lever has two
A lever head, one of lever head are embedded in the sleeve, another lever head is connected with the telescopic rod of the piston, described
Piston drives the sleeve to move back and forth axially along using lever head and lever.
Further, the piston is connect by signal with peripheral control unit.By peripheral control unit, realizes and pass through work
The axial movement of the extension and contraction control sleeve of plug has abandoned in traditional technology and has realized that sleeve moves axially by manual swing handle
Process, improve efficiency, reduce labor intensity.
Further, it is threaded with screw rod on the nut, one end of the screw rod is fixedly connected with the spring, described
The other end of screw rod stretches out the mounting base and is connected with handle, and the handle adjusts the length of the spring by screw rod.
, can be according to the length of needs of production adjustment spring by above structure, i.e. adjustment spring is transmitted to top
The elastic force of axis namely the top active force being applied on workpiece so that this structure can adapt in various sizes of workpiece, simultaneously
Avoid the phenomenon that grinding machine processes fixed effect variation and the machining accuracy reduction of workpiece after a certain period of time.
Further, it is arranged with dustproof cover on the sleeve and screw rod, the outer wall of the dustproof cover and the mounting base
It is fixedly connected.
Further, at least two lubricating cups are offered at the top of the mounting base, which passes through oil duct and the set
The outer wall of cylinder is connected.
Pass through above structure so that in the deep enough sleeve of lubricating oil energy and bearing, efficiently avoid sleeve and bearing
Abrasion, reduce later maintenance cost.
Further, it is also equipped in the mounting base and to be fixedly connected with platen for realizing tailstock assembly
T slot fixing screws.
The remarkable result of the utility model is：It is simple in structure, it is easy to use, piston telescopic rod is controlled by peripheral control unit
It stretches out or shrinks so that tailstock sleeve moves along its axis certain distance, and then controls the top spacing between workpiece and occur
Change, realizes clamping workpiece or release, compared to conventional manual structure, labor intensity is greatly reduced, and improves production efficiency；
Top pressure is adjusted by the length of adjustment spring simultaneously, avoids the fixed effect of grinding machine processing certain time consequent
The phenomenon that variation, is effectively guaranteed machining accuracy.
