Abstract

The utility model relates to a double-tip mechanism with a driving capability for a lathe. The double-tip mechanism comprises a tail tip and a head tip component, wherein the tail tip is a conventional tip, and the head tip component comprises a clamping body, a moveable tip and at least three columnar flexible stirring blades. The clamping of a workpiece through the double tips and the rotating driving of the workpiece can be realized by the double-tip mechanism with the driving capability for the lathe; besides, the clamping forces of the flexible stirring blades of the double-tip mechanism for the end face of the workpiece can be increased following the increasing of the rotating speed.

Description

Two tip mechanisms with transmission capacity for lathe

Technical field

The utility model relates to the technical field of machining, particularly relates to the two tip mechanisms with transmission capacity for a kind of lathe.

Background technology

The development of clamp technology comes from the requirement of user Geng Gao.Nowadays, in Machining of Shaft-type Parts, traditional clamping chuck mode can not meet user to part high accuracy and high efficiency requirement, and a kind of novel jig-end face drives top, and the advantage in Machining of Shaft-type Parts is further obvious.Drive the top and tailstock centre positioning workpieces in top dependence center, driving pusher dog to embed workpiece end face makes it rotate with machine tool chief axis, thereby chuck and heart carrier are abandoned completely, clamped one time is without turning around, can complete axle journal, end face, grooved and screw thread processing, in turning milling center, also can once complete the processing of keyway and oilhole, thereby working (machining) efficiency significantly improve, axiality and position degree are more guaranteed, are applied to more and more widely turning, grinding and the gear hobbing processing of axial workpiece.Lathe spindle rotating speed increasingly high, to traditional clamp technology, serious challenge is proposed: no matter be axial workpiece or disk cover parts, when the speed of mainshaft of lathe exceedes after certain limit, the limit speed that is installed on the hydraulic cylinder of rear-end of spindle will become the further principal element of raising of restriction cutting speed.Therefore, adopt end face actuation techniques just to become one of very important developing direction of speed lathe fixture dynamically lower.

Utility model content

The purpose of this utility model is in order to address the above problem, and the two tip mechanisms with transmission capacity for a kind of lathe are provided.

The technical solution of the utility model is: the two tip mechanisms with transmission capacity for a kind of lathe, comprise the top and top assembly of head of tail, described tail is top is conventional top, and the top assembly of described head comprises cramping body, rolling center, at least three flexible swords of stirring of column; Described cramping body one end is installing handle, and the other end is plate-like fixing body, is provided with axial hole at the axis position of fixing body, and described rolling center is arranged in this axial hole, between top the inner and the inner face of axial hole, is provided with axial support spring; Be provided with at least three cylinder holes at the end face of fixing body, the described flexible sword of stirring is arranged in cylinder hole, is provided with three radial blind holes that are at least communicated with spindle hole bottom on the periphery of fixing body; In described radial blind holes, be provided with wedge block, the inherent flexible the inner of stirring sword of described cylinder hole is provided with the decorative pearl on top of an official cap, and the inclined-plane of described wedge block contacts with this decorative pearl on top of an official cap, between the inner of wedge block and the bottom of radial blind holes, is provided with radial support spring.

The diameter of described installing handle mates with lathe spindle diameter.

The beneficial effects of the utility model

Two tip mechanisms with transmission capacity for this lathe, can realize the sharp holding workpiece of Double Tops and realize the rotary actuation of workpiece, and the flexible sword of stirring of this tip mechanism can improve along with the raising of rotating speed the clamping dynamics of workpiece end face in addition.

Accompanying drawing explanation

Fig. 1 is that this lathe is looked cross-sectional view with the master of the two tip mechanisms with transmission capacity;

1. installing handles in figure, 2. fixing body, 3. radial support spring, 4. wedge block, 5. radial blind holes, 6. the decorative pearl on top of an official cap, 7. flexible stir sword, 8. rolling center, 9. axial support spring, 10. tail is top.

The specific embodiment

Embodiment: referring to Fig. 1, two tip mechanisms with transmission capacity for a kind of lathe in figure, comprise the top and top assembly of head of tail, described tail is top be conventional top, and the top assembly of described head comprises that cramping body, rolling center, at least three columns stretch and stir swords; Described cramping body one end is installing handle, and the other end is plate-like fixing body, is provided with axial hole at the axis position of fixing body, and described rolling center is arranged in this axial hole, between top the inner and the inner face of axial hole, is provided with axial support spring; Be provided with at least three cylinder holes at the end face of fixing body, the described flexible sword of stirring is arranged in cylinder hole, is provided with three radial blind holes that are at least communicated with spindle hole bottom on the periphery of fixing body; In described radial blind holes, be provided with wedge block, the inherent flexible the inner of stirring sword of described cylinder hole is provided with the decorative pearl on top of an official cap, and the inclined-plane of described wedge block contacts with this decorative pearl on top of an official cap, between the inner of wedge block and the bottom of radial blind holes, is provided with radial support spring.The diameter of described installing handle mates with lathe spindle diameter.

The course of work of this mechanism:

When use, top head assembly is arranged on lathe spindle, adjust fixing, then workpiece is arranged on rolling center and tail top between, compress to rolling center by lathe accessories driving machine tail centre, force the flexible blade of stirring sword outer end to embed workpiece end face, thereby realize workpiece transmitting torque, after lathe spindle High Rotation Speed gets up, drive the top assembly rotation of head, wedge block is because the effect meeting of centrifugal force departs to the direction away from axle center, thereby the promotion decorative pearl on top of an official cap, and promote flexible stir sword and move to workpiece end face, further promote the chucking power to workpiece, rotating speed is higher, stretching, it is more firm with being connected of workpiece to stir sword.

Claims (2)

1. the two tip mechanisms with transmission capacity for lathe, comprise the top and top assembly of head of tail, it is characterized in that: described tail is top for conventional top, the top assembly of described head comprises cramping body, rolling center, at least three flexible swords of stirring of column; Described cramping body one end is installing handle, and the other end is plate-like fixing body, is provided with axial hole at the axis position of fixing body, and described rolling center is arranged in this axial hole, between top the inner and the inner face of axial hole, is provided with axial support spring; Be provided with at least three cylinder holes at the end face of fixing body, the described flexible sword of stirring is arranged in cylinder hole, is provided with three radial blind holes that are at least communicated with spindle hole bottom on the periphery of fixing body; In described radial blind holes, be provided with wedge block, the inherent flexible the inner of stirring sword of described cylinder hole is provided with the decorative pearl on top of an official cap, and the inclined-plane of described wedge block contacts with this decorative pearl on top of an official cap, between the inner of wedge block and the bottom of radial blind holes, is provided with radial support spring.
2. the two tip mechanisms with transmission capacity for lathe according to claim 1, is characterized in that: the diameter of described installing handle mates with lathe spindle diameter.
