Abstract
The utility model provides a double-end flexible ball fixture capable of transmitting torque. According to the technical scheme, the double-end flexible ball fixture capable of transmitting torque comprises a drive plate, a left ejector pin, a left ball ejector pin sleeve, a heart carrier, a right ball ejector pin sleeve and a flexible ejector pin, wherein the left ejector pin is arranged on an inner hole of the drive plate, a taper shank of the left ejector pin is matched with a Morse's taper hole in a lathe spindle, a tip portion of the left ejector pin is arranged in a taper hole of the left ball ejector pin sleeve in a sliding match mode, the drive plate is in thread connection with the heart carrier, the heart carrier fixedly clamps a workpiece and transmits torque, a taper shank of the flexible ejector pin is matched with a Morse's taper hole in a lathe tailstock sleeve, a tip portion of the flexible ejector pin is arranged in a taper hole of the right ball ejector pin sleeve in a sliding match mode, and balls on the left ball ejector pin sleeve and the right ball ejector pin sleeve abut against a left end center hole and a right end center hole of the workpiece respectively. The double-end flexible ball fixture has the advantages that relative movement is absent between an ejector pin ball head and the workpiece, processing accuracy is greatly improved, and service life of the fixture is greatly prolonged.
Description
Technical field
The utility model relates to a kind of active ball fixture of double end of energy transmitting torque, belongs to Machining Technology field.
Background technology
ball push pin device is usually used in tail stock skew turning process, be mainly used in processing the workpiece that circular cone oblique angle is less, the conical surface is grown, in actual use, because ball thimble maintains static, workpiece rotation, the centre bore sliding friction of the ball on ball thimble and workpiece, make very quick-wearing of thimble bulb, cause workpiece centre location inaccurate, the workpiece tapering processing produces error, does not reach technical requirement on design.
Summary of the invention
The purpose of this utility model is just to provide a kind of active ball fixture of double end of energy transmitting torque, for addressing the above problem.
The technical solution of the utility model is: a kind of active ball fixture of double end of energy transmitting torque, comprise driver plate, left thimble, left ball tailstock barrel, heart carrier, right ball tailstock barrel and movable thimble, left thimble is set on the endoporus of driver plate, Morse's taper hole on taper shank and the lathe spindle of left thimble matches, the top tip part of left thimble is arranged on sliding matching mode in the taper hole of left ball tailstock barrel, driver plate and heart carrier screw thread are connected, the clamping workpiece transmitting torque of heart carrier, Morse's taper hole on the taper shank of movable thimble and tail stock sleeve matches, the top tip part of movable thimble is arranged on sliding matching mode in the taper hole of right ball tailstock barrel, ball on left ball tailstock barrel and right ball tailstock barrel heads on respectively left end centre bore and the right-hand member centre bore of workpiece.
The beneficial effects of the utility model are: thimble bulb and workpiece are without relative motion, and machining accuracy and fixture improve service life greatly.
Brief description of the drawings
Fig. 1 is the utility model mounting structure schematic diagram.
Detailed description of the invention
Known with reference to accompanying drawing 1, a kind of active ball fixture of double end of energy transmitting torque, comprise driver plate 2, left thimble 3, left ball tailstock barrel 4, heart carrier 5, right ball tailstock barrel 7 and movable thimble 8, left thimble 3 is set on the endoporus of driver plate 2, Morse's taper hole on the taper shank of left thimble 3 and lathe spindle 1 matches, the top tip part of left thimble 3 is arranged on sliding matching mode in the taper hole of left ball tailstock barrel 4, driver plate 2 is connected with heart carrier 5 screw threads, clamping workpiece 6 transmitting torques of heart carrier 5, Morse's taper hole on the taper shank of movable thimble 8 and tail stock sleeve 9 matches, the top tip part of movable thimble 8 is arranged on sliding matching mode in the taper hole of right ball tailstock barrel 7, ball on left ball tailstock barrel 4 and right ball tailstock barrel 7 heads on respectively left end centre bore and the right-hand member centre bore of workpiece 6.When work, first press accompanying drawing 1 this device and workpiece 6 are installed, and tighten the screw holding workpiece 6 on heart carrier 5, shake again tail stock top tight workpiece 6, can start lathe and start processing, now the top tip part of left thimble 3, left ball tailstock barrel 4, right ball tailstock barrel 7 and movable thimble 8 all with workpiece 6 synchronous rotaries, the bulb of tailstock barrel is without wearing and tearing, whole useful life period, keeps very high positioning precision from start to finish, improve service life more than 4 times, the utility model is applicable to fine finishining and high-speed cutting.
