Description
Technical field
The invention belongs to dismantling technology field, be specifically related to a kind of drawing extracting tool.
Background technology
Respectively run in parts at diesel engine, the assembling having many parts is interference fit, once these interference fit
Parts have damage, it is necessary to dismounting and change again, and the dismounting for these parts is quite not easy, it is common that use hammer,
The instruments such as pliers cooperate and are pulled out or pull out, and the method is bothersome arduously, and is also easy to nothing in unloading process
Damage part and cause damage.For such issues that, the frock tool used at present has two classes, a class to be by the way of grabbing instrument outward
Dismounting；Another kind of is to dismantle by the way of interior pulling out.Both of which is first to be fixed parts, carries out outer grabbing the most again
Or the mode inside pulled out goes to dismantle.For above mechanical type drawing extracting tool, it it is exactly additionally fluid pressure type drawing dismounting
Instrument, fluid pressure type drawing device cost is high, uses and keeps in repair the most more complicated.This kind of frock tool is typically all special drawing
Instrument, is also for a kind of or dismounting of a type component interference fit, and versatility is not strong, and function is more single.
Summary of the invention
For solving above-mentioned technical problem, the purpose of the present invention proposes a kind of drawing extracting tool.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of drawing extracting tool, described drawing dismantling device includes leading screw, nut and hook claw bar；The two ends of described leading screw
All stretch out described nut, and be respectively provided with the tetragonal body in order to be connected with spanner at the two ends of leading screw；The periphery of described nut
On there is the supporter being uniformly distributed along the circumference, have round-meshed rhombus centered by described supporter；The center tool of described hook claw bar
There is through hole, and the axis of described through hole is perpendicular to hook the axis of claw bar；The two ends of described hook claw bar are respectively provided with in order in dismounting
Hook the hook pawl of pawl part during part, and the hook pawl that hook is described in claw bar two ends is centrosymmetric；Described hook claw bar is corresponding three institutes
Three of the supporter setting stated；Each described hook claw bar is hinged with corresponding supporter by connecting plate；Described company
Fishplate bar is two pieces；The upper end of two pieces of described connecting plates, lower end are respectively provided with the through hole passed in order to bolt；Described bolt is two
Individual, one of them bolt passes through the through hole of one piece of connecting plate upper end, hooks the circular hole at claw bar center, another block connecting plate upper end
Through hole, and fastened by nut, another bolt pass through the through hole of one piece of connecting plate upper end, the circular hole at supporter center,
The through hole of another block connecting plate upper end, and fastened by nut, make described connecting plate be articulated as one with corresponding supporter.
The present invention proposes a kind of drawing extracting tool, uses technique scheme, both can directly catch outside parts
Edge carries out drawing, in can being deep into again hole, parts is carried out drawing, it is achieved thereby that the parts to all kinds of interference fit
Carry out drawing dismounting, the problem solving a lot of drawing device function singleness, and there is simple in construction, and easy to operate, versatility
Good feature.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As it is shown in figure 1, and combine Fig. 2, a kind of drawing extracting tool, described drawing dismantling device includes leading screw 1, spiral shell
Mother 2 and hook claw bar 3；Described nut 2 is all stretched out at the two ends of described leading screw 1, and be respectively provided with at the two ends of leading screw 1 in order to spanner
The tetragonal body connected；In conjunction with Fig. 3, the periphery of described nut 2 has the supporter 7 being uniformly distributed along the circumference, described supporter 7
Centered by have round-meshed rhombus；In conjunction with Fig. 4, the center of described hook claw bar 3 has through hole, and the axis of described through hole is perpendicular to
Hook the axis of claw bar；The two ends of described hook claw bar 3 are respectively provided with the hook pawl in order to hook pawl part when dismantling part, and hook claw bar
Hook pawl described in two ends is centrosymmetric；Described hook claw bar 3 is three that corresponding three described supporters 7 are arranged；Each institute
The hook claw bar 3 stated is hinged with corresponding supporter 7 by connecting plate 4；Described connecting plate 4 is two pieces；Two pieces of described connections
The upper end of plate 4, lower end are respectively provided with the through hole passed in order to bolt 5；Described bolt 5 is two, and one of them bolt 5 is through it
In one piece of connecting plate upper end through hole, hook the circular hole at claw bar center, the through hole of another block connecting plate upper end, and fastened by nut,
Another bolt pass through the through hole of one piece of connecting plate upper end, the circular hole at supporter center, another block connecting plate upper end logical
Hole, and fastened by nut 6, make described connecting plate be articulated as one with corresponding supporter.
When carrying out the crawl of part, catching on the edge of parts by hooking the pawl that hooks of claw bar 3, screw mandrel 1 withstands parts
Middle part, tightens by hand screw mandrel 1, makes hook claw bar 3 touch the edge of supporter of nut, makes each hook pawl hook tight parts limit simultaneously
Edge, re-uses spanner and twists the tetragonal prism of screw mandrel 1, by applying force to reach to extract the parts of interference fit.
When drawing in carrying out part, drawing extracting tool is extend in hole, catch on parts with the pawl that hooks hooking claw bar 3
Edge, screw mandrel 1 withstands the middle part of parts, tightens by hand screw mandrel 1, makes hook claw bar 3 touch the support rhombus of supporter nut 2
The edge of body, makes each hook pawl hook tight parts edge simultaneously, re-uses spanner and twist the tetragonal prism of screw mandrel 1, reach by applying force to
To the parts extracting interference fit.
