Embodiment
In order to illustrate more clearly of the technical scheme of the utility model embodiment, it will use below required in embodiment
Accompanying drawing be briefly described, it should be apparent that, drawings in the following description are some embodiments of the present utility model, for this
For the those of ordinary skill of field, on the premise of not paying creative work, it can also obtain other according to these accompanying drawings
Accompanying drawing.
A kind of Combined wheel puller 10, including support base 20, jack 30, two adjusting rods 40, some regulating blocks 50, use
Holding firmware 60 in clamping part 90 to be removed, locknut 70 is tightened, the bottom of the jack 30 is consolidated with the front side wall of support base 20
Fixed connection, the front end of jack 30 is used to hold out against part 90 to be removed, and the support base 20, which is provided with, to be used to insert adjusting rod 40
Groove 201, the height of groove 201 and the diameter matches of adjusting rod 40, the width of groove 201 are more than the diameter of adjusting rod 40, with
Adjusting rod 40 is set to be moved left and right in groove 201, two adjusting rods 40 are separately positioned on the both sides of jack 30, the adjusting rod
40 front end passes through the groove 201 of support base 20, and is fixedly connected with holding firmware 60, rear end and the regulation locknut 70 of adjusting rod 40
Connection, regulating block 50 is provided with through hole, and some regulating blocks 50 are set in the adjusting rod 40 between regulation locknut 70 and support base 20
On outer wall, it is threadedly coupled between regulation locknut 70 and the rear end of adjusting rod 40, after the front end and the regulating block 50 that adjust locknut 70
End in contact, the front end of regulating block 50 is contacted with the rear wall of support base 20 with by rotating regulation locknut 70 and adjustment regulating block 50
Quantity adjust the length of the adjusting rod 40 of the front end of support base 20 so that front end and the expansion link of jack 30 of adjusting rod 40
The thickness matching of length difference and part 90 to be removed between 301, so that the expansion link 301 of jack 30 withstands on part 90 to be removed
In the rotating shaft at place.
Further, the axis of the expansion link 301 of the axis of two adjusting rods 40 and jack 30 in the same plane, is adjusted
The front end of pole 40 sets external screw thread, and the rear end of holding firmware 60 sets internal thread, and adjusting rod 40 and holding firmware 60 are threadedly coupled, with
Holding firmware is convenient for changing, part 90 to be removed is located between holding firmware 60 and support base 20.
In a better embodiment, jack 30 is bolted to connection with support base 20.
Further, two hangers 80 are set on the support base 20, and part 90 to be removed is connected with hanger 80 by rope,
To be pounded when preventing part 90 to be removed from being come off from axle to operating personnel.
Further, the front end of the holding firmware 60 is threaded rod 601, to install nut 602, the diameter of threaded rod 601
Identical with the diameter of the through hole of part 90 to be removed, the length of threaded rod 601 is more than after the thickness of part 90 to be removed, holding firmware 60
Hold to be cylindric, and provided with screwed hole, to connect adjusting rod 40, the diameter of the rear end of holding firmware 60 is more than the logical of part 90 to be removed
The diameter in hole, part 90 to be removed is clamped between the rear end of nut 602 and holding firmware 60.
It is during using Combined wheel puller 10 of the present utility model, the step of a kind of preferably embodiment:
S101, the threaded rod 601 of holding firmware 60 passes through the through hole of part 90 to be removed, and then fixing nut 602, make to be removed
Part 90 is clamped between the rear end of nut 602 and holding firmware 60;
S102, the quantity of regulating block 50 is added according to actual conditions, while rotation tightens locknut 70, so as to tighten locknut 70
Locking, the expansion link 301 of jack 30 and part 90 to be removed between locking, regulating block 50 and support base 20 between regulating block 50
Between hold out against so that the expansion link 301 of jack 30 is withstood on the axle where part to be removed 90;
S103, operates jack 30, the expansion link 301 of jack 30 is gradually extended, if where part to be removed 90
Axle is fixed, then with the elongation of the expansion link 301 of jack 30, in the presence of nut 602, Combined wheel puller 10
Part to be removed 90, support base 20, the adjusting rod 40 of clamping are moved to the opposite direction of the prolonging direction of the expansion link 301 of jack 30
It is dynamic, so that part to be removed 90 progressively disengages axle;If part 90 to be removed is fixed, then axle where part to be removed 90 with
The expansion link 301 for jack 30 is gradually ejected, so that part to be removed 90 is separated with axle.
Because part 90 to be removed is integrally fixed on holding firmware 60, then when part 90 to be removed departs from from axle, as long as
Staff would not fall on the ground holding support base 20, part 90 to be removed suddenly.
Further, the holding firmware 60 is sickle shaped, and the rear end of holding firmware 60 is provided with screwed hole, to connect adjusting rod
40, the front end of holding firmware 60 sets kink 603, with by kink by the clamping of part 90 to be removed.
The step of another better embodiment of Combined wheel puller 10 of the present utility model is:
S201, the kink of falculate holding firmware 60 is stuck in the outer rim of part 90 to be removed, and part 90 to be removed is pressed from both sides
Hold between the rear end of kink 603 and holding firmware 60;
Follow-up step and the S102 in previous embodiment, S103 are identical.
On the basis of Combined wheel puller 10 of the present utility model, it can also subsequently extend the holding firmware of many types
60, so that real work needs are adapted to, therefore expansion of the present utility model is stronger.The utility model also has stronger adaptation energy
Power, can make corresponding adjustment according to thickness, hole depth, diameter of part 90 to be removed etc..
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, one of ordinary skill in the art will appreciate that realize all or part of flow of above-described embodiment, and according to this reality
The equivalent variations made with new claim, still fall within the scope that utility model is covered.
