Technical field

The present invention relates to a kind of novel tapered sleeve and axis of cone coupling arrangement, the device wide range of applications is applicable Positioning before work pieces process also can satisfy needs when certain class type replaces the axis of cone when power and energy.

Background technique

It can be seen that, most of coupling for the axis of cone and tapered sleeve is fixed by bolts (such as lathe from existing technology The chuck of upper clamping cutter) or (dress used when replacing roller on such as most of intaglio printing press in such a way that one end is held out against Set), above-mentioned fixed device greatest drawback be it is time-consuming and laborious when changeing the axis of cone or tapered sleeve, it is inefficient.Or it cannot be guaranteed the axis of cone With the circumferential relative position relationship of tapered sleeve.The application patent is exactly to solve drawbacks described above.

Summary of the invention

The purpose of the present invention is to provide the coupling arrangements of a kind of quick-detachable axis of cone and tapered sleeve, it not only can guarantee The axis of cone couples reliably with tapered sleeve, and can be with quick separating, while can also be further ensured that the axis of cone and the circumferential of tapered sleeve align.

The present invention is realized by following technical proposals.A kind of coupling arrangement of the quick-detachable axis of cone and tapered sleeve, packet The axis of cone and tapered sleeve are included, it is characterized in that: the spindle nose position of the axis of cone processes an inner conical surface, the axle center of tapered sleeve opens up screw slot, screw rod Screw rod is installed in slot and screw rod is set with pressure spring, the union end of tapered sleeve installs steel ball fixing seat, and one end of screw rod is solid across steel ball Connecting rod after reservation, pull rod is equipped with inclined-plane by steel ball fixing seat end, if the inclined-plane of pull rod is fixed together with steel ball fixing seat Dry steel ball, the other end transverse shifting driving mechanism of screw rod, tapered sleeve are fixed in fixing seat, axial immovable, can circumferentially be revolved Turn；There is a flat key above the axis of cone, there is a keyway on tapered sleeve.

Further preferably, the transverse shifting driving mechanism by double threaded screw, connector, cylinder, cylinder fixed support and is dialled Bar is constituted, and the other end of screw rod connects double threaded screw, and double threaded screw is connect with connector；Cylinder is fixed on by cylinder fixed support On pedestal, the piston rod and dead man of cylinder are hinged；Dead man connects double threaded screw.

The present invention provides the coupling methods of a kind of quick-detachable axis of cone and tapered sleeve, the specific steps are as follows:

1, the spindle nose position of the axis of cone processes an inner conical surface, and the axle center of tapered sleeve opens up screw slot；Before the axis of cone is unassembled, it will bore Set is fixed in fixing seat, axial immovable, can circumferentially be rotated；

2, pass through the external screw thread of steel ball fixing seat after pull rod, steel ball, steel ball fixing seat, pressure spring, screw rod one component of composition It is connect with tapered sleeve；Between pull rod and steel ball fixing seat, screw rod passes through steel ball fixing seat and is fixedly connected with pull rod, compression spring sleeve steel ball On screw rod；Pressure spring is in pre-pressing state at this time, is jacked up steel ball by the inclined-plane of pull rod, and steel ball is higher by steel ball fixing seat Outer circle, but must not fall off；

3, the other end of screw rod connects double threaded screw, and double threaded screw is connect with connector；

4, cylinder is fixed on the base by cylinder fixed support, and the piston rod and dead man of cylinder are hinged, dead man and connector Cooperation；

5, when assembling the axis of cone, by the operation button of lower cylinder, cylinder pushes dead man, drives connector to be moved to the left, double end spiral shell Bar, screw rod are moved to the left simultaneously, and pressure spring is compressed；Pull rod is moved to the left, and steel ball moves down after losing support, and is lower than steel The outer circle of pearl fixing seat is put into tapered sleeve for the axis of cone and gets ready；

6, it will be put into the internal taper hole of tapered sleeve equipped with the axis of cone of flat key, while guarantees that key and keyway are put to consistent, pressed again Operation button, cylinder drive dead man move right, pull rod, screw rod and double threaded screw, connector under the endogenetic process of pressure spring, to Move right, steel ball moves upwards under the active force on pull rod inclined-plane at this time, on uphill process with the inner cone face contact of the axis of cone, the axis of cone It is moved right under the active force that steel ball squeezes outer inclined-plane, after coincideing with the inner conical surface of tapered sleeve and manages stress always, it is complete At the axis of cone and tapered sleeve couple and fastening.

The present invention processes an inner conical surface at the spindle nose position of the axis of cone, outer inclined-plane is pushed using multiple steel balls, to reach It is axial to push the entire axis of cone, the inner conical surface of the outer cone of the axis of cone and tapered sleeve is cooperated closely, formation is fixedly connected；It is bored when needing to unclamp When the cooperation in face, steel ball is moved down, and is released stress, while the axial pre tightening force of the conical surface loses, and the axis of cone can be light with tapered sleeve It loosens；Steel ball move up and down and steel ball push outer inclined-plane strength size be to be realized by one with bevelled pull rod , pull rod is realized axial tension and strength control by a built-in pressure spring.Existing pull rod is quickly closed in order to reach Axial displacement, in pull rod connecting screw, screw rod reconnects double threaded screw, and there is a connector in one end of double threaded screw, the connector with Cylinder linkage drives connector when cylinder moving, and pushing drawing rod moves axially, and realizes the upper and lower position switching of steel ball, thus Realize the axis of cone and the disengagement of tapered sleeve with couple.For the circumferential position relationship for guaranteeing the axis of cone and tapered sleeve, there is one above the axis of cone Flat key has a keyway on tapered sleeve.When installing the axis of cone, by lower cylinder control button, pull rod further compresses pressure spring at this time, to the left Mobile, steel ball moves down simultaneously, after the keyway of the key alignment tapered sleeve in the axis of cone, is inserted into tapered sleeve.Lower cylinder control is pressed again Button, pull rod drive steel ball to move up under the strength of pressure spring, and steel ball is pressed in the outer inclined-plane of the axis of cone, realize the axis of cone automatically with cone Set connection, and realize circumferentially positioned function.

The device of the invention not only can guarantee that the axis of cone couples reliably with tapered sleeve, and can be with quick separating, while can also be into one Step guarantees that the axis of cone and the circumferential of tapered sleeve align.The device wide range of applications, the positioning before being applicable to work pieces process, It can satisfy needs when certain class type replaces the axis of cone when power and energy.
