Its main points are: pulling out and drawing the seat to go up the cover to have the sleeve, be equipped with the screw rod on the sleeve, the sleeve draws the seat for left -handed screw is connected, and screw rod swing joint with pulling out, it has barrel -shaped supporting seat, the inner circumference and the telescopic outer periphery sliding connection of supporting seat still to overlap on the sleeve, be equipped with the hand wheel on the screw rod, hand wheel and screw rod threaded connection pull out to draw the screw and pull out to draw and are equipped with the regulation gasket between the seat. The utility model discloses a pin extractor, simple structure, to make easy expense low, and operation convenient to use pulls out and only need rotate the hand wheel when unloading the pin and can slowly extract pin, labour saving and time saving, to the pin of different models, only need to change pulling out of corresponding and draw the screw and adjust the gasket, improved the utilization ratio of extractor, economic nature is good, pulling out the locating surface that unloads shi buhui damage coupling assembling and pin, not needing relocalisation when adorning again, reliability and security are good.
Description
Technical field
The utility model relates to a kind of puller, is specifically related to a kind of for the pin extractor with internal thread hole.
Background technology
Pin dismounting in mechanized equipment repair, the destructive modes such as general employing is beaten, drill through, are easy to the assembly precision of destruction existing equipment, reduce the quality of production, shorten equipment life.For reducing the damage of pin dismounting to equipment, the mode of adopt manpower to draw, pulling out, to dismantle pin, although this mode is better than traditional approach, still exists: one is that required withdrawal force is very large, and labor strength does not reduce; Two is pull out unbalance stress when unloading, and easily damage the joint face of puller or the pin that fractures, even injuring part, cause from new assembling and positioning inaccurate, the equipment that affects normally works.This just needs a kind of time saving and energy saving, easy to operate, can not the pin extractor of injuring part body.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing for above-mentioned technology, provides that a kind of structure is simple, easy to operate, time saving and energy saving, the pin extractor of good reliability.
Pin extractor of the present utility model, comprises pulling out and draws screw, pulls out pulling seat, it is characterized in that: the described cover on pulling seat that pulls out has sleeve, and sleeve is provided with screw rod, sleeve with pull out pulling seat and be threaded, be flexibly connected with screw rod; On described sleeve, also cover has supporting seat; Described supporting seat is barrel shaped structure, and bottom is provided with screw hole, and the inner peripheral surface of supporting seat and the outer circumference surface of sleeve are slidably connected; Described screw rod is provided with handwheel, and handwheel is connected with screw flight.
In order to better realize above-mentioned purpose:
Described sleeve is that left hand thread is connected with pulling out pulling seat.
Conveniently change pulling out of different model and draw screw, described pulling out is drawn screw and is pulled out between pulling seat and be provided with adjustment pad.
Pin extractor of the present utility model, simple, the easy to manufacture expense of structure is low, easy for operation, pulls out only need rotate handwheel when unloading pin and easily can extract pin, time saving and energy saving; For the pin of different model, only need change corresponding pulling out and draw screw and regulate pad, improve the utilization rate of extractor, good economy performance; Pull out the connection locating surface that can not damage coupling assembling and pin when unloading, do not need when reassembling to reorientate, reliability and security good.

Detailed description of the invention
Pin extractor of the present utility model, comprises pulling out and draws screw 7, pulls out pulling seat 6.To pull out on pulling seat 6 cover and have sleeve 5, sleeve 5 is provided with screw rod 1, sleeve 5 with pull out pulling seat 6 for left hand thread and be connected, be flexibly connected with screw rod 1.Screw rod 1 on sleeve 5 is through the screw hole of the bottom centre of barrel-shaped supporting seat 4, and upwards push away supporting seat 4, be enclosed within by supporting seat 4 on sleeve 5, the inner peripheral surface of supporting seat 4 and the outer circumference surface of sleeve 5 are slidably connected.Screw rod 1 is provided with handwheel 2, and handwheel 2 is threaded with screw rod 1.
Conveniently change pulling out of different model and draw screw 7, to pull out the pin 8 drawing different model, pull out to draw screw 7 and pull out to be provided with between pulling seat 6 and regulate pad 9.
During use, pull out and draw screw 7 successively through regulating pad 9 and pulling out pulling seat 6, and draw screw 7 to be screwed in the screwed hole of pin 8 by pulling out, the lower surface of the upper surface and coupling assembling 10 of pulling out pulling seat 6 is adjacent to; Sleeve 5 is enclosed within screw rod 1, and left-handed being screwed in is pulled out on pulling seat 6; Screw rod 1 is through the screw hole of the bottom centre of supporting seat 4, and upwards push away, be enclosed within by supporting seat 4 on sleeve 5, the inner peripheral surface of supporting seat 4 and the outer circumference surface of sleeve 5 are slidably connected; Packing ring 3 to be contained on screw rod 1 and to be adjacent to the lower surface of supporting seat 4, finally handwheel 2 being contained in packing washer 3 on screw rod 1, the lower surface of the annular end face of supporting seat 4 and coupling assembling 10 is adjacent to.Rotation hand wheel 2, screw rod 1 moves down and is with moving sleeve 5 successively, pulls out pulling seat 6 and pull out and draw screw 7 to move down, and can be extracted by the pin 9 on coupling assembling 10 slowly.
Pull out when unloading, time saving and energy saving, can not damage the connection locating surface of pin 8 and coupling assembling 10, reassemble and facilitate accurate positioning, for the pin 8 of different model, only need change corresponding adjustment pad 9 and pull out and draw screw 7, can complete pulling out of pin 8 and unload, practicality is good.
