Abstract

The utility model provides an overload-protection wire twisting chuck. The wire twisting chuck comprises a chuck body and a shaft handle, wherein a circular die chuck passes through the chuck body; a steel ball spring type clutch mechanism comprising a steel ball, a clutch sleeve, a spring and a regulating nut is connected between the chuck body and the shaft handle; the spring is sleeved on the shaft handle; one end of the spring is propped against the clutch sleeve; the other end of the spring is propped against the regulating nut; and the regulating nut is matched with screw threads in the middle of the shaft handle for use. The wire twisting chuck is characterized in that a step through hole is formed in the center of the circular die chuck; and a circular die is mounted in the step hole and fastened through a screw passing through the periphery of the circular die chuck. When the wire twisting operation runs into barriers, that is, when the cutting force is increased to exceed the torque of the clutch mechanism, the steel ball spring type clutch mechanism slips, and the cutting operation is suspended, so that cutting tools are protected, and workpieces cannot be damaged. The wire twisting chuck has the characteristics of simple structure, safety, reliability, and the like, and is convenient to use.

Description

A kind of overload protection hinge silk chuck
Technical field
The utility model relates to a kind of overload protection hinge silk chuck, belongs to machine tool accessories.
Background technology
Chinese patent CN2120650U discloses " a kind of tap holder "; but provide a kind of overload protection tap holder that can protect screw tap and intuitive and convenient ground to regulate moment of torsion effectively; owing in the tap chuck in this tap holder circular die can not be installed; so in machining with circular die when silk hinge; can make the cutting force overload of hinge silk for various reasons and cause circular die to damage, influence crudy and progress.
Summary of the invention
The purpose of this utility model just provides a kind of overload protection hinge silk chuck, is used to address the above problem.
The purpose of this utility model is achieved in that this hinge silk chuck comprises collet body and footstalk, the circular die chuck is through in the collet body, connect with flat key therebetween, and it is fastening with screw, between collet body and footstalk, be connected with steel ball, clutch sleeve, the steel ball and spring formula clutch that spring and adjusting nut are formed, spring housing is on footstalk, one end withstands on the clutch sleeve, the other end withstands on the adjusting nut, adjusting nut and footstalk middle part threaded engagement are used, steel ball is between clutch sleeve and collet body, the ball-and-socket of settling steel ball is arranged on the contact-making surface of clutch sleeve and collet body and steel ball, be connected with feather key between clutch sleeve and the footstalk, it is characterized in that the center of described circular die chuck is provided with step through-hole, circular die is installed in the stepped hole, and it is fastening by the screw of circular die chuck periphery.
From the above, when hinge silk runs into obstacle, when promptly cutting force increased to moment of torsion above clutch, steel ball spring formula clutch slided, and cutting is interrupted, and cutlery is protected, and workpiece is not damaged.
The utlity model has characteristics such as simple in structure, safe and reliable, easy to use.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
The contrast accompanying drawing as can be known, the utility model comprises collet body 1 and footstalk 2, circular die chuck 3 is through in the collet body 1, connect with flat key 10 therebetween, and it is fastening with screw 11, between collet body 1 and footstalk 2, be connected with steel ball 4, clutch sleeve 5, the steel ball and spring formula clutch that spring 6 and adjusting nut 7 are formed, spring 6 is enclosed within on the footstalk 2, one end withstands on the clutch sleeve 5, the other end withstands on the adjusting nut 7, adjusting nut 7 uses with footstalk 2 middle part threaded engagement, steel ball 4 has the ball-and-socket of settling steel ball on the contact-making surface of clutch sleeve 5 and collet body 1 and steel ball 4 between clutch sleeve 5 and collet body 1, be connected with feather key 12 between clutch sleeve 5 and the footstalk 2, the center that it is characterized in that described circular die chuck 3 is provided with step through-hole, and circular die 8 is installed in the stepped hole, and it is fastening by the screw 9 of circular die chuck 3 peripheries.
During work, the taper shank of footstalk 2 is inserted in the tail stock hole, workpiece 13 clampings are on the lathe scroll chuck, after lathe spindle rotates, shaking tail stock moves, workpiece 13 is contacted with circular die 8, along with the rotation of workpiece and the feeding of tail stock, circular die 8 axially incision workpiece 13 cuts with scissors an operation, runs into obstacle in hinge silk process, when cutting force increases suddenly, surpass spring 6 tension force, steel ball spring formula clutch skids, and cutting is interrupted, thereby guaranteed not schizodont of circular die 8, workpiece 13 does not damage.
