Tight disassembly installation.
The utility model additionally provides a kind of working method of single thrust dual-positioning clamping jaw swelling telescoping mechanism, packet
Include following steps:
When the telescoping mechanism of present embodiment stretches out, driving mechanism pushes second level telescopic shaft 8 to be moved by its rear end forward end
It is dynamic, so that thimble 4 be pushed to be moved by its rear end forward end, so that the pyramidal structure of 4 front end of thimble is matched with swollen pawl 7, and push up
Needle 4 is not pierced by expansion set 3, and spring 9 is pressurized, and driving mechanism stops driving (as illustrated in fig. 1 and 2)；Due to first order telescopic shaft 2 with lead
The elastic force of spring 9, therefore second level telescopic shaft 8, thimble 4, first order telescopic shaft are much smaller than to the force of sliding friction between casing 1
2 and expansion set 3 become a rigid body, spring 9 elastic force effect under, second level telescopic shaft 8, thimble 4, first order telescopic shaft 2
With expansion set 3 it is integrated it is mobile relative to guide sleeve 1, until first order telescopic shaft 2 is directed to 1 axial limiting of casing, i.e., the
The rear end that first positioning shaft shoulder 20 of level-one telescopic shaft 2 is directed to casing 1 is blocked, and the front end of expansion set 3 is penetrated to part at this time
In the inner hole of processing, the positioning of present embodiment telescoping mechanism and inner bore of part is so realized；When first order telescopic shaft 2 is led
When to 1 axial limiting of casing, driving mechanism pushes second level telescopic shaft 8 to be moved by its rear end forward end again, and the first order is flexible
Axis 2 and expansion set 3 are not moved relative to guide sleeve 1, and second level telescopic shaft 8 and thimble 2 are continued to move to relative to guide sleeve 1,
The front end of expansion set 3 is pierced by the pyramidal structure of thimble 4, so that the front end of multiple swollen pawls 3 is by 4 distending of thimble (as shown in fig. 3 to 7),
The machined inner hole of such multiple swollen 7 swelling parts of pawl, realizes the telescoping mechanism of present embodiment and the reliable peace of inner bore of part
Dress.During the telescoping mechanism of present embodiment stretches out, the waist type groove of the cylindrical end of cylinder end clamping fixed screw 5 in thimble 4
It is moved in 401, does not interfere the movement of thimble 4, expansion set 3, first order telescopic shaft 2 and second level telescopic shaft 8.When first order telescopic shaft
2 when being directed to 1 axial limiting of casing, and first order telescopic shaft 2 and expansion set 3 are not moved relative to guide sleeve 1, and the second level is flexible
For axis 8 relative to first order telescopic shaft 2 there are also the distance moved forward, i.e. the second positioning shaft shoulder 80 of second level telescopic shaft 8 is opposite
There is spacing between the seam allowance face of the major diameter seam allowance of first order telescopic shaft 2.When the pyramidal structure of 4 front end of thimble and swollen pawl 7 match
It closes, and when thimble 4 is not pierced by expansion set 3, swollen 7 front end of pawl sinks to the opening 301 of expansion set 3 far from second arc head in thimble direction
It is interior；When the front end of multiple swollen pawls 7 is by 4 distending of thimble, swollen pawl 7 is rotated relative to expansion set 3 around hinge assembly, so that before swollen pawl 7
The part of the second arc head far from thimble direction is held to screw out expansion set 3, thus the inner hole that 7 swelling part of swollen pawl is machined, wherein
First arc head of swollen 7 rear end of pawl moves in arc groove 402.The design of arc groove 402, with prevent swollen pawl 7 relative to
When expansion set 3 rotates, the interference rotation of thimble 4.During thimble 4 is pierced by expansion set 3, swollen 7 front end of pawl close to 4 direction of thimble
Two arc heads are moved along the pyramidal structure of thimble 4.
When the telescoping mechanism retraction of present embodiment, driving mechanism drives second level telescopic shaft 8 to be moved to the back-end by its front end
It is dynamic, so that thimble 4 is mobile to the back-end by its front end so that thimble 4 bounces back in expansion set 3, at this time swollen pawl 7 relative to expansion set 3 around
Hinge assembly convolution, until 7 front end of swollen pawl is sunk in expansion set 3 far from second arc head in thimble direction, the no longer swelling part of expansion set 3
Machined inner hole；Driving mechanism continues to drive second level telescopic shaft 8 mobile to the back-end by its front end, when thimble 4 is moved to hook
Firmly when the cylindrical end of cylinder end clamping fixed screw 5, first order telescopic shaft 2, thimble 4, second level telescopic shaft 8 and expansion set 3 are integrated
Ground is mobile relative to guide sleeve 1, so that expansion set 3 is deviate from from the machined inner hole of part, so realizes present embodiment
The fast demoulding of telescoping mechanism.When thimble 4 bounces back in expansion set 3, under the action of reset spring of hinge assembly, swollen pawl 7 is certainly
It is dynamic to circle round relative to expansion set 3 around hinge assembly.
In present embodiment under the action of guide sleeve 1, the guide function of present embodiment telescoping mechanism is realized, greatly
Kinematic accuracy is improved greatly.Under the single driving force effect of driving mechanism, Internal hole positioning swelling function is not only realized, it is also fast
Demoulding functions are realized fastly, are greatly improved work efficiency, while in turn ensuring the required precision of coaxiality of inner hole, and this reality
The mode of applying can be suitably used for driving force request few, the more operating condition of positioning requirements.Present embodiment is compact-sized simultaneously, occupied space
It is small, to apply also for the small occasion of installation space.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model
