Description
Technical field
The present invention relates to a kind of mechanical fitting field more particularly to a kind of devices of quick assembling stud.
Background technology
Currently, the general assembling process of stud is：First two hex nuts are screwed at one to tighten, passed through with spanner
Other end is screwed into engine base, then removed two nuts with two spanners by nut, upper-cover is refilled, then by washer and nut set
Upper screw rod, tightens nut.Process is cumbersome, and ineffective labor amount is big, and efficiency is low.There is the special of some assembling studs on the market at present
With tool, mainly it is divided to two classes：1st, automatically controlled programming device reaches quick rotation by the screwing force of the advance accurate control screw thread of programming
Enter, the purpose easily screwed out, this equipment there are it is expensive, use environment is more demanding, poor universality, accessory type are more etc.
Defect；2nd, mechanical device is more typically more than screw thread equivalent friction angle using helix of thread lift angle, screw thread is made to lose self-locking
Principle, the ingenious application of screw structure is achieved the purpose that into rapid-assembling/disassembling Double-ended nut, this structure includes leading screw at least by 5
Class part forms, and there are the defects of complicated, core component leading screw cost is higher.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of device of quick assembling stud, and the present invention is used to solve
Certainly more easily stud is assembled the engine base the technical issues of.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of device of quick assembling stud, including：
Stud, one end of stud are equipped with the first external screw thread, and the other end, which is equipped with, to be used for being bolted in external engine base
Second external screw thread；
Sleeve, one end of sleeve are the operation structure operated for spanner, and the other end has round platform, the outer end face of the round platform
It offers along the axially extending circular channel of sleeve, offers on the round platform and lead to through circular channel and the transverse direction that radially extends
Road, the interconnection form two jacks on the side wall of circular channel；
Round nut, loaded on the circular channel in the round nut, have in the round nut in the cooperation of the first external screw thread
Screw thread is opened up on the round nut there are two waist-shaped hole corresponding with jack, and the outward opening of each waist-shaped hole is more than inner opening；
Cylindrical pins, the cylindrical pins are connected to two jacks and two waist-shaped holes, and the cylindrical pins and jack
Interference fit, the cylindrical pins and waist-shaped hole clearance fit.
Preferably, a square slot of the operation structure to offer the square key insertion for external key on sleeve.
Compared with the prior art, the beneficial effects of the present invention are：Round nut and wrench socket are passed through cylinder by the present invention
The ingenious connection of pin achievees the effect that spanner nut this pretightning force is less than and is screwed into engine base that screw fastening clamp force, so as to
Make to reduce most unnecessary work during assembling stud to engine base, efficiency of assembling, present invention tool can be greatly improved
Have the advantages that simple in structure, easily fabricated, of low cost.
Description of the drawings

Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the present invention is described further：
As shown in Figure 1, a kind of device of quick assembling stud, including：
Stud 5, one end of stud 5 are equipped with the first external screw thread, and the other end, which is equipped with, to be used for being bolted in external engine base 6
The second external screw thread；
Sleeve 2, one end of sleeve 2 are the operation structure operated for spanner 1, and the other end has a round platform, the round platform it is outer
End face is offered along the axially extending circular channel of sleeve 2, is offered on the round platform through circular channel and is radially extended
Interconnection, the interconnection form two jacks on the side wall of circular channel；
Round nut 4, the round nut 4 is interior loaded on the circular channel, and the round nut 4 is interior to have what is coordinated with the first external screw thread
Internal thread is opened up on the round nut 4 there are two waist-shaped hole 31 corresponding with jack, and the outward opening of each waist-shaped hole 31 is more than interior
Opening；
Cylindrical pins 3, the cylindrical pins 3 are connected to two jacks and two waist-shaped holes 31, and the cylindrical pins 3 with
Jack is interference fitted, the cylindrical pins 3 and 31 clearance fit of waist-shaped hole.
As a preferred solution, the operation structure is inserted into for the square key 11 offered on sleeve 2 for external key 1
A square slot 21.
Referring to Fig. 1, a kind of occupation mode of the device of quick assembling stud, since its structure is sleeve 2, straight pin
Nail 3 and round nut 4 be assembled together group device.Sleeve 2 is sleeved on spanner 1, and cylindrical pins 3 are fastened to by interference fit
On sleeve 2；Cylindrical pins 3 and the waist-shaped hole of round nut 4 are clearance fits, and screwing force is passed to round nut 4 by waist-shaped hole；
During urgent stud 5, cylindrical pins 3 withstand the bolt head of stud 5, generate end face support reaction F1, which causes
Circumferential frictional force f1 and nut pretightning force F2 stud 5 is screwed in the threaded hole of engine base 6 together, at this time two resultant force（f1、
F2）The pretightning force F3 generated equal to engine base threaded hole；After urgent stud 5, when reversely screwing out round nut 4, due to waist-shaped hole
Presence, cylindrical pins 3 reversion will not encounter round nut 4 at once, at this time only cylindrical pins 3 follow sleeve 2 invert, it is only necessary to gram
Taking the frictional force f1 that end face support reaction generates can just rotate, and f1 is less than F3, and stud 5 will not be carried over；When cylindrical pins 3
Going to the waist-shaped hole other end will drive round nut 4 to back-out, and at this moment need to only overcome round nut pretightning force F2 can be by 4 band of round nut
Go out, and F2 is less than F3, stud 5 will not be carried over.In this way in urgent stud 5, spanner 1 need to only be rotated forward urgent right
Reversely back-out the purpose that the present invention can reach quick assembling stud 5 afterwards.
The present invention has the characteristics that simple and compact for structure, easy to operate, efficiency of assembling is high, of low cost, is easy to market and pushes away
Extensively.
It will be apparent to those skilled in the art that technical solution that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection domain of the claims in the present invention
Within.
