Abstract
The utility model relates to a tailstock locking device used to resolve the technical problem of unreliable locking of the prior tailstock locking device on the machine tool, comprising a bolt for a T-shaped groove, a gland nut, a disk spring, a piston, an oil seal and a housing. The tailstock locking device is characterized in that a piston is arranged on the housing , and an oil seal is arranged on the piston; the open end of the housing is screwed with a compression nut, and a disk spring is arranged between the compression nut and the piston. The connecting shaft of the piston goes through the disk spring and is connected with the T-shaped bolt for groove. The tailstock locking device has the advantages of automatically loosening and locking and adjusting the size of locking force in advance, so as to secure the consistence of locking forces of all the locking devices under the same condition.
Description
Technical field
The utility model relates to a kind of tail stock for machine tool locking device, the especially a kind of locking device that can realize auto lock and loosen function.
Background technology
At present, general tail stock for machine tool locking device is to be locked with screw bolt and nut by T type groove, unclamps with locking and need manually finish, waste time and energy, and the difficult control of the uniformity of coupling mechanism force, it is unreliable to lock.
Summary of the invention
The utility model is in order to solve the insecure technical problem of locking of tailstock locking device on the existing lathe, providing a kind of clamps with mechanical spring, the hydraulic unlock mode, can finish the tailstock locking device that unclamps with locking action automatically, the big I of this device coupling mechanism force is adjusted in advance, can guarantee the unanimity of all locking device coupling mechanism forces under the identical service condition.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of tailstock locking device, comprise T type groove bolt, clamp nut, disk spring, piston, oil sealing, the body shell is characterized in: the body shell is equipped with piston, piston is provided with oil sealing, be rotary with clamp nut on the body shell opener end, between clamp nut and the piston disk spring be housed, the connecting axle of piston passes disk spring and is connected with bolt with T type groove.
Piston nose is provided with guide finger, and the guide finger front end is inserted in the body shell Feng Miduan; The body shell is rotary with the installation nut outward.
The beneficial effects of the utility model are, adopt the single-acting hydraulic jack, when the tailstock inactive state, do not provide pressure oil, disk spring pretension by rod chamber provides downward thrust, tailstock is locked on the machine tool guideway, when needing the state of movable tail frame, high-pressure and hydraulic oil is fed, act on the oil cylinder rodless cavity piston area, further the compression spring sheds the initial tension of spring that acts on the tailstock, to move freely tailstock.Guarantee the reliability of tailstock locking, improved the automaticity of lathe.
Description of drawings
Fig. 1 is a longitudinal section view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the embodiment shown in fig. 1, tailstock locking device of the present utility model is made up of with bolt 1, clamp nut 2, disk spring 3, piston 4, guide finger 5, oil sealing 7, installation nut 8, body shell 9 T type groove.
Body shell 9 is equipped with piston 4, and piston 4 is provided with oil sealing 7, is rotary with clamp nut 2 on body shell 9 openends, between clamp nut 2 and the piston 4 disk spring 3 is housed, and the connecting axle of piston 4 passes disk spring 3 and is connected with bolt 1 with T type groove.
Piston 4 front ends are provided with guide finger 5, and guide finger 5 front ends are inserted in the close end of body shell 9 envelopes; Body shell 9 outer being rotary with are installed nut 8.
When locking state, the hydraulic oil in the oil pocket 6 is communicated with fuel tank, no pressure, and disk spring 3 provides tailstock locking required precompression by screwing clamp nut 2.The big I of coupling mechanism force is adjusted by the displacement of clamp nut 2 compression disk springs 3.When releasing orientation, feed pressure oil in the oil pocket 6, compression disk spring 3 makes T type groove throw off with the bolt 1 and the contact-making surface of lathe, sheds coupling mechanism force, with regard to movable tailrack.
