Abstract
The invention relates to a pin puller for dismounting pins. The pin puller comprises a cylindrical supporting seat, a sleeve in sleeved connection with the inner wall of the supporting seat to play a guiding role and a screw penetrating the supporting seat and the center of a cavity of the sleeve, wherein the supporting seat and the top end of the sleeve are provided with though holes for the screw to pass through, one end of the sleeve is in threaded connection with a double-end bolt, the other end of the sleeve is sleeved by a hand wheel, and the other end of the double-end bolt is in threaded connection with a pin. The pin puller has the advantages that the pin is easily pulled out but is not damaged, the labor intensity of a user is reduced, and the labor efficiency is improved.
Description
Technical field
The present invention relates to a kind of pin removal.
Background technology
Pin removal is a kind of instrument often using in maintenance work, in maintenance work, dismantling the method that pin is conventional is to pound out, to such an extent as to some assemble accurate parts after dismounting several times, locate no longer accurate, thereby cause variety of issue, had a strong impact on it and normally used, and maintenance personal's the amount of labour and potential safety hazard very large.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of pin removal.
The present invention solves the technical scheme that its technical problem adopts: a kind of pin removal, be used for dismantling pin, comprise supporting base cylindraceous, be socketed on the sleeve that supporting base inwall play the guiding role and run through supporting base and sleeve chamber in the screw rod of central authorities, the top of supporting base and sleeve all offers is convenient to the through hole that screw rod passes through, the threaded one end of sleeve is connected with stud, the other end of sleeve is arranged with handwheel, and the other end of stud is connected with pin thread.
Further, between handwheel and supporting base, be connected with thrust bearing.
The invention has the beneficial effects as follows: pin is more drawn out easily and is not damaged, and has reduced user's labour intensity, and has improved efficiency.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Wherein: 1. pin, 2. stud, 3. sleeve, 4. supporting base, 5. screw rod, 6. thrust bearing, 7. handwheel.
Detailed description of the invention
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention instead of limitation of the invention further.
A kind of pin removal as shown in Figure 1, be used for dismantling pin 1, comprise supporting base 4 cylindraceous, be socketed on the sleeve 3 that supporting base 4 inwalls play the guiding role and run through screw rod 5 central in supporting base 4 and sleeve 3 chambeies, supporting base 4 all offers and is convenient to the through hole that screw rod 5 passes through with the top of sleeve 3, the threaded one end of sleeve 3 is connected with stud 2, the other end of sleeve 3 is arranged with handwheel 7, and the other end of stud 2 is threaded with pin 1.
Between handwheel 7 and supporting base 4, be connected with thrust bearing 6.
When actual use, first sleeve 3 is put into supporting base 4, then screw rod 5 is passed from the endoporus of sleeve 3, supporting base 4; Then these two is linked up by the internal thread hole of pin 1 and the internal thread hole of screw rod 5 with stud 2; Then handwheel 7 is spun on screw rod 5, slowly rotation hand wheel 7, can extract pin.Not only reduce user's labour intensity, and improved efficiency.
Because sleeve 3 play the guiding role in supporting base 4, can make pin 1 slowly extract under stressed uniform state, not only ensure that the surface of pin 1 and pin hole is not damaged, operate also safer.After adding lubricating oil in withdrawal process, effect is better, and has substantially avoided the situation that stud 2 fractures in pinhole to occur.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
