Description
Technical field
The utility model relates to frock technical field, particularly a kind of for pulling out the frock of alignment pin.
Background technology
Dismounting technical fields such as keeping in repair, do over again at parts, tends to relate to the dismounting of alignment pin.
Domestic some company has developed pin removal specially at present, and these pin removals all adopt manpower drawing.A some pin pulling tooling equipment in use people not enough, needs two people to operate simultaneously, and operating efficiency is lower, also waste of manpower.But along with mass, the mechanization of producing, work rhythm is more and more faster, only rely on the mode of manually pulling pin can not meet Production requirement gradually.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of for pulling out the frock of alignment pin, can adopt pneumatic impact wrench to be used in conjunction with and realize quick drawing.
The technical solution adopted in the utility model is such: a kind of for pulling out the frock of alignment pin, comprise fairlead, fixed cover, bolt, axle, in described fixed cover left end, establish dowel hole and a circle bolt hole is set on sidewall, in fixed cover right-hand member, screwed hole is set, described fairlead is enclosed within outside fixed cover, on its left half section of wall, the gathering sill corresponding with bolt hole is set vertically, right-hand member arranges flat arbor hole two, described bolt is through gathering sill, then be threaded onto in bolt hole and stretch in dowel hole always, left half section of described axle is also established thread segment for flat part and left end, this thread segment is left successively through the arbor hole one on spacer, arbor hole two on fairlead, then be threaded onto in the screwed hole of fixed cover right-hand member, the flat part of axle is through in the arbor hole two of fairlead, axle right-hand member is locked spacer with nut.
As preferably, described bolt hole one encloses and is evenly provided with three, and correspondingly, the gathering sill on fairlead also has three.
As preferably, described nut is hex nut.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: when operation, coordinate pneumatic impact wrench one people just to complete and to pull pin very soon, automaticity is high, and the efficiency of pulling pin is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
Most preferred embodiment:
For pulling out a frock for alignment pin, comprise nut 1, spacer 2, fairlead (3), fixed cover 4, bolt 5, axle 6, this programme whole structure figure is as shown in Figure 1.
In described fixed cover 4 left ends, establish dowel hole 4-2 and a circle bolt hole 4-3 is evenly set on sidewall, totally three bolt hole 4-3, arrange screwed hole 4-1 in fixed cover 4 right-hand members, as shown in Figure 5,6.
Described fairlead 3 is enclosed within outside fixed cover 4, on its left half section of wall, three gathering sill 3-2s corresponding with bolt hole 4-3 is set vertically, and right-hand member arranges flat arbor hole two 3-1, as shown in Figure 3,4.
Described bolt 5, through gathering sill 3-2, is then threaded onto in bolt hole 4-3 and stretches in dowel hole 4-2 always.
On described spacer 2, right-hand member is provided with arbor hole one 2-1, as shown in Figure 2.
Left half section of described axle 6 is also established thread segment 6-2 for flat part 6-1 and left end, as shown in Figure 7,8.
Described thread segment 6-2 is left successively through arbor hole one 2-1, arbor hole two 3-1 on fairlead 3 on spacer 2, then be threaded onto in the screwed hole 4-1 of fixed cover 4 right-hand members, the flat part 6-1 of axle 6 is through in arbor hole two 3-1 of fairlead 3, and axle 1 right-hand member is locked spacer 2 with nut 1.
Described nut 1 is hex nut.
Use step:
The first step, sends into alignment pin in the dowel hole 4-2 of fixed cover 4 left ends;
Second step, overlaps the gathering sill 3-2 of fairlead 3 and bolt hole 4-3 therein by fixed cover 4 from right to left to it, and it is fastening in bolt hole 4-3, to be located pin 7 with bolt 5;
The 3rd step, arbor hole two 3-1 by axle 6 through fairlead 3 right-hand members, then the thread segment 6-2 of left end is threadedly connected in the screwed hole 4-1 of fixed cover 4, and flat part 6-1 are stuck in arbor hole two 3-1;
The 4th step, is enclosed within spacer 2 in axle 6 and also locks with nut 1;
The 5th step, utilizes pneumatic impact wrench to coordinate continuous fastening nut 1, and axle 6 drives fixed cover 4 constantly to pull out outward alignment pin 7.
When tightening, nut 1 also can drive axle 6 to rotate, due to the fit structure of the flat part 6-1 in arbor hole two 3-1 and axle 6 on fairlead 3, also can there is synchronous rotation in fairlead 3 and fixed cover 4, in the process that fixed cover 4 is pulled out, bolt 5 can constantly slide to the right in gathering sill 3-2.
