Abstract
The utility model discloses a kind of studs installation tool, including rocking bar, tool body, retainer, ball, back-up ring and cover plate；Described rocking bar is that the force application part of instrument is linked together by Type of Welding with described tool body；Described tool body is the basic components of whole installation tool, is used for installing each parts of support；Described retainer is used for fixing described ball；Described ball contacts with studs and can roll；Described back-up ring and cover plate are used for fixing described retainer；Instrument is put into when studs installed by the instrument described in this utility model polished rod position in the middle of stud, and rotating rocker installs studs, simple to operation, will not damage the face coat of stud, be effectively improved the installation effectiveness of big specification studs.
Description
Technical field
The frame for movement technology that this utility model relates to is, one will not damage big specification studs face coat and
The device of big specification studs installation effectiveness can be improved.
Background technology
The pitch variable bearings of 2MW, 5MW serial wind-driven generator group and yaw have employed substantial amounts of big specification studs
Connected mode, owing to the special construction of studs causes clamping inconvenience in assembling and dissembling process, it is common that hands when installing studs
Stud is threaded in hole by work, if the difficulty of being screwed into, then two nut checks of employing are in studs one end, then use open-end wrench
It is screwed into；With two open-end wrench, the nut of two lockings is unclamped during dismounting, withdraw one by one.This method not only can be damaged double
The screw thread coating of header stud, and add the labor intensity of workman, have a strong impact on production efficiency.
Therefore, it is necessary to design a kind of studs that can be quickly installed will not damage again studs face coat
Installation tool.
Summary of the invention
The purpose of this utility model is, for the problems referred to above, proposes a kind of studs installation tool, to realize quickly
Studs and don't the advantage that can damage studs face coat are installed simply.
For achieving the above object, the technical solution adopted in the utility model is: a kind of studs installation tool, including shaking
Bar, tool body, retainer, ball, back-up ring and cover plate；Described rocking bar is that the force application part of instrument passes through with described tool body
Type of Welding links together；Described tool body is the basic components of whole installation tool, is used for installing each parts of support；Institute
State retainer for fixing described ball；Described ball contacts with studs and can roll；Described back-up ring and cover plate are used for
Fixing described retainer.
In this utility model, described rocking bar, in bow word shape, is connected to one with described tool body by the form welded
Rise.
In this utility model, described tool body is provided with three road arcuate furrows and installs described back-up ring and the draw-in groove of cover plate
And screwed hole.
In this utility model, described retainer is provided with three holes less than described ball.
In this utility model, described ball is spheroidal through surface hardening heat treatment.
Ball described in this utility model and retainer keep being relatively fixed with the position of studs, work as installation tool
When body is rotated clockwise under the effect of frictional force 3 balls and tool body circular arc locking face and studs polished rod
Part forms reliable and stable self-locking, finally makes installation tool and studs form one, thus easily installs double end spiral shell
Post；Simple in construction, realizes integration with studs itself well；Low cost of manufacture, manufacturing enterprise is easily accepted by；This practicality is new
Type is widely used in the installation of large-scale wind electricity enterprise and other manufacturing enterprises big specification studs.
Have the advantage that
Can be installed by the studs being sized to be applicable to all size of change tool body；
Ball processes through surface hardening, and service life is long；
Needed for rocking bar is designed to arc-shaped, rotary installation tool, power is less, and installation effectiveness is high.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is partial sectional view of the present utility model.
In figure, 1. rocking bar, 2. tool body, 3. back-up ring and cover plate, 4. ball, 5. retainer.
Detailed description of the invention
Seeing Fig. 1 to Fig. 3, a kind of studs installation tool, including rocking bar 1, tool body 2, back-up ring and cover plate 3, rolling
Pearl 4, retainer 5；Rocking bar 1 is that the force application part of instrument is linked together by Type of Welding with tool body 2；Tool body 2
It is the basic components of whole installation tool, is used for each parts of support are installed；Retainer 5 is used for fixing ball 4；Ball 4 and double end
Stud contact also can roll；Back-up ring and cover plate 3 are for fixed retainer 5.
During assembling stud, instrument being put into studs, dextrorotation is shaken bar 1 and is driven tool body 2 to rotate, and is rubbing
The lower ball 4 of the effect of wiping power forms reliable and stable self-locking with tool body 2 circular arc locking face and studs polished rod part,
Assembly tool is made to form one with studs eventually.Continue turn installation tool rocking bar and just easily double threaded screw can be screwed into change oar
In bearing threads hole.
When opposite direction turn installation tool rocking bar 1, ball 4 and tool body 2 circular arc locking face and studs polished rod
It is partially disengaged, and stud pretightning force existing with pitch variable bearings screw thread will not be carried over, the most just can be taken off installation tool and complete dress
Join.
Preferably, rocking bar 1, in bow word shape, is linked together by the form welded with tool body 2.By changing work
The size structure size of tool body 2 is adapted to the studs of different size and installs.
Preferably, tool body 2 is machined with three road arcuate furrows and back-up ring and the draw-in groove of cover plate 3 and screwed hole are installed.
When needs change tool interior ball 4 and retainer 5, unclamp fixing bolt just detachable back-up ring and cover plate 3 thus take out work
Tool internal part.
Preferably, retainer 5 machined three holes less than ball 4 so that ball contacts after self-locking with studs
Form one without dropping on retainer 5.
Preferably, ball 4 is spheroidal through surface hardening heat treatment.Processed by surface hardening, the hardness of ball 4
Reach certain value, improve the service life of instrument.
This utility model is not limited to above-mentioned embodiment, uses identical with this utility model above-described embodiment or approximation
Structure and other studs installing mechanisms of obtaining, all within protection scope of the present invention.
