Description
Technical field
The utility model belongs to break-in tool technical field, and in particular to a kind of nut dismantling device.
Background technology
In the prior art to dismantling, repairing the occasion for thering is the time limit to require, such as：The industries such as railway, chemical industry, because nut is just
It is difficult to dismantle in the case of often or in the case of getting rusty, directly affects dismounting, the time limit repaired, typically cut using oxy-acetylene,
The methods of manual sawing, carries out the destructive dismounting of nut, and nut, which gets rusty, can also meet in not uh the situation daily life that can dismantle
Arrive.And in general Manual disassembling tool one is dangerous, such as forbids the occasion got angry；Second, efficiency is low；Third, not only break up
After nut also destroys bolt, not only extends the time of reparation, and bolt is destroyed, the cost of reparation is added, very
It can extremely result in greater loss.
The content of the invention
The purpose of this utility model is to provide a kind of nut dismantling device, the nut for problems of the prior art
Dismantling device is simple in construction, easy to use and do not allow destructible bolt.
The technical solution of the utility model is：
A kind of nut dismantling device, including push rod, described pusher section are extend into connecting cylinder, and push rod is by setting outer spiral shell
Line is threadedly coupled with the internal thread set in connecting cylinder, other end attaching nut's stationary half of connecting cylinder, nut stationary half
With the junction providing holes of connecting cylinder, be equipped with forcible entry cutter in hole, forcible entry cutter include cutter head and and knife bar, dismantle cutter
Cutter head is located in nut stationary half, and the knife bar for dismantling cutter is located in connecting cylinder.
Specifically, being provided with steel ball in described connecting cylinder, steel ball is between forcible entry cutter and push rod.
Specifically, the cross section triangular shape of the cutter head of described forcible entry cutter.
Specifically, the cutter head of forcible entry cutter and being formed in one structure with knife bar.
The beneficial effects of the utility model are：It is novel in design, simple in construction, easy to use, safe, time saving and energy saving, efficiency
Height, and to bolt not damaged, both shortened dismounting, repair time, and saved rehabilitation cost again, and be mainly used in railway, chemical industry
It is difficult to dismounting under normal circumstances etc. industry nut or is difficult to the destructive dismounting dismantled in the case of getting rusty.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1 nut stationary half, 2 connecting cylinders, 3 forcible entry cutters, 4 steel balls, 5 push rods, 6 internal threads,
7 external screw threads.
Embodiment
It is a kind of structural representation of nut dismantling device as shown in Figure 1.It includes push rod 5, and the described part of push rod 5 is stretched
Enter into connecting cylinder 2, push rod 5 by setting the internal thread 6 set in external screw thread 7 and connecting cylinder 2 to be threadedly coupled, connecting cylinder 2
Other end attaching nut stationary half 1, the junction providing holes of nut stationary half 1 and connecting cylinder 2, forcible entry is equipped with hole
Cutter 3, forcible entry cutter 3 include cutter head and are located at knife bar, the cutter head of forcible entry cutter 3 in nut stationary half 1, dismantle cutter 3
Knife bar be located in connecting cylinder 2.Steel ball 4 is provided with described connecting cylinder 2, steel ball 4 is between forcible entry cutter and push rod 5.
The cross section triangular shape of the cutter head of described forcible entry cutter 3.Dismantle the cutter head of cutter 3 and be integrated with knife bar
Molding structure.
When dismantling nut using the utility model, nut stationary half 1 is enclosed on above the nut that need to be dismantled, then slowly
Screwing push rod 5, push rod 5 promotes steel ball 4 to travel forward, and steel ball 4 heads on forcible entry cutter 4 and moved, by effect of the cutter head to nut,
Cutting nut open slowly comes, so as to reach the purpose of forcible entry.The effect of steel ball 4 is that the stress of forcible entry cutter 4 can be made equal
It is even, it is unlikely to deviation when forcible entry and damages bolt.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
