Abstract
The utility model relates to 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.The beneficial effects of the utility model are: pin is more drawn out easily and is not damaged, and has reduced user's labour intensity, and has improved efficiency.
Description
Technical field
The utility model 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.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of pin removal.
The utility model 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 beneficial effects of the utility model are: 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 utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. pin, 2. stud, 3. sleeve, 4. supporting base, 5. screw rod, 6. thrust bearing, 7. handwheel.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
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 utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
