Abstract
A fast clutch mechanism for a lead screw comprises a power shaft, a bearing, a support, a left clutch sleeve, a right clutch sleeve, a rotary sleeve, a safety pin, a lead screw shaft, a fixing pin, a steel sleeve, a positioning steel ball set and a handle. The power shaft is supported in an inner hole of the support through the bearing. The power shaft is connected with the left clutch sleeve. The right clutch sleeve is matched with the inner hole of the support and can move in the axial direction. An inner hole of the right clutch sleeve is matched with the lead screw shaft. The outer end of the safety pin fixed to the lead screw shaft is clamped into an axial groove of the right clutch sleeve. The rotary sleeve is installed on the excircle of the support in a matched mode through a shaft hole. The fixing pin on the rotary sleeve penetrates through a semi-spiral groove in the support and enters an outer annular groove of the right clutch sleeve. The rotary sleeve is provided with the operating handle and the positioning steel ball set. The left clutch sleeve and the right clutch sleeve are designed to be of end face rectangular tooth structures on the contact end faces. Connection and transmission are achieved through combination of end face teeth. The power shaft rotates while the lead screw does not rotate when the end face teeth are separated.
Description
Technical field
The present invention relates to the connection clutch in machine driving, belong to mechanical driving device, be mainly used in machine driven system needing the work of clutch
Make situation.
Background technology
In machine driven system, between axle group connect structure have a lot, fixed cover can connect but can not clutch, mechanical friction clutch structure
Compared with big and easily skid, transmission accuracy low.
Summary of the invention
For realize little space between the axle group of mechanical mechanism, in high precision, high reliability clutch transmission, the present invention provides a kind of screw mandrel Quick clutch mechanism,
This mechanism is capable of the fast clutch of screw mandrel and power between centers, and self structure is compact, and screw mandrel connects, stable drive is reliable.
The technical scheme is that the Quick clutch mechanism for mechanical lead screw transmission, including line shaft, bearing, bearing, left clutch cover, the right side
Clutch cover, pivoted housing, safety pin, screw axis, steady pin, steel bushing, locking ball group, handle.Described line shaft is bearing in bearing by bearing
Inner hole surface, power axle head is fixedly connected with left clutch cover by pin, and described right clutch cover cylindrical coordinates at bearing endoporus and can move axially, right
The endoporus of clutch cover coordinates with screw axis, and described screw axis is fixed with safety pin, and safety pin outer end snaps in the axial groove of right clutch cover, described
Pivoted housing be arranged on the cylindrical of bearing by shaft hole matching, the steady pin on pivoted housing enters into right clutch cover excircle through the semi-spiral groove on bearing
Annular groove, steady pin top is provided with the steel bushing lowering friction, described pivoted housing is provided with control crank and locking ball group realizes right clutch cover and axially determines
Position.Described left clutch cover, right clutch cover are designed as end face rectangular teeth structure at contact end face, and end-tooth is implemented in combination with connecting transmission, and end-tooth divides
From the rotation of then line shaft, screw mandrel does not turns.
During application, handling the handle on pivoted housing and rotate, by rotating and move axially in steady pin helicla flute on bearing, steady pin end steel bushing leads to
Crossing annular groove drives right clutch cover to left movement, and right clutch cover is combined with left clutch cover, and line shaft passes motion to screw mandrel, when handle inverts pivoted housing and
Right clutch cover adverse movement, right clutch cover separates with left clutch cover, and line shaft rotates and screw mandrel does not turns.
Accompanying drawing 1 is one screw mandrel Quick clutch mechanism figure of the present invention.
Detailed description of the invention
Seeing accompanying drawing, the present invention provides a kind of screw mandrel Quick clutch mechanism, including line shaft 1, bearing 2, bearing 3, left clutch cover 4, right clutch
Set 5, pivoted housing 6, safety pin 7, screw axis 8, pin 9, steel bushing 10, steady pin 11, locking ball group 12, handle 13.Described line shaft
1 is bearing in bearing 3 inner hole surface by bearing 2, and line shaft 1 axle head is fixedly connected with left clutch cover 4, described right clutch cover cylindrical by pin 9
Coordinating at bearing 3 endoporus and can move axially, the endoporus of right clutch cover 5 coordinates with screw axis 8.
Being fixed with safety pin 7 on described screw axis 8, safety pin 7 outer end snaps in the axial groove of right clutch cover 5, and described pivoted housing 6 passes through axle
Hole cooperation is arranged on the cylindrical of bearing 3, and the steady pin 11 on pivoted housing 6 enters into right clutch cover 5 excircle through the semi-spiral groove on bearing 3
In annular groove, steady pin 11 top is provided with the steel bushing 10 lowering friction.
Control crank 13 and locking ball group 12 it is provided with on described pivoted housing 6.Described left clutch cover 4, right clutch cover 5 design at contact end face
For end face rectangular teeth structure, end-tooth is implemented in combination with connecting transmission, and end-tooth separates, and line shaft rotates and screw mandrel does not turns.
