Description
Technical field
The present invention relates to assembly tooling and the assembly method thereof of a kind of circlip for hole.
Background technology
Circlip is also jump ring or clasp, belongs to the one of securing member, for being contained in machine, the axial trough of equipment or hole slot
In, play a part the part axial motion stoped on axle or on hole.Owing to circlip uses the multiformity of environment, cause one
In particular cases assemble difficulty a bit, need to overcome huge axial force the most when mounted, traditional assembly tool Circlip tongs without
Method completes assembling, and uses dedicated elas-tic back-up ring fitting machine cost high, inconvenience of remodeling.
Summary of the invention
Goal of the invention: for the problems referred to above, the purpose of the present invention one is to provide the assembly tooling of a kind of circlip for hole,
Not only can easily overcome huge axial force when assembling, and assembling can be completed at low cost；Another of the present invention
Purpose is to provide the assembly method using this assembly tooling.
Technical scheme: the assembly tooling of a kind of circlip for hole, is U-shaped lead and with annular including longitudinal section
Boss press-fit bar, perforation is offered at described lead center, and described lead is inverted and is made its U-shaped mouth downward, described in press-fit bar set
Entering inside described lead, described annular boss and diapire overlap joint in described lead, described annular boss diameter is slightly less than to be treated
The workpiece hole diameter of dress circlip, described in press-fit bar lower end diameter less than circlip aperture to be installed.
Along described perforation shift outward, described lead longitudinal direction cut-out is formed tangent plane, described lead is inverted in
Time above the workpiece hole of circlip to be installed, described tangent plane is made to form mismatch with workpiece hole.
The U-shaped mouth diameter of described lead is slightly less than the workpiece hole diameter of circlip to be installed, can make elasticity during assembling
Back-up ring enters in workpiece hole smoothly, is possible to prevent circlip resilience to enter in U-shaped mouth simultaneously.
The assembly method of above-mentioned use assembly tooling, is directed to post inversion and makes its U-shaped mouth downward, will press-fit bar and be inserted in guiding
Inside post, press-fit bar one end and pass perforation, circlip and pad are enclosed within and press-fit the bar other end, be positioned over together in workpiece hole
On workpiece with spring, press-fit the bar other end and stretch into spring, above lead, impose axial force, annular boss to press-fiting bar
Acting on circlip promotes it to overcome downwards spring force, thus is pressed in the groove in workpiece by circlip, completes assembling.
The mismatch formed by tangent plane and workpiece hole observes circlip, uses Circlip tongs to stretch into clamping elasticity gear in mismatch
Circle, auxiliary pushing circlip overcomes downwards spring force.
Impose axial force by hydraulic pressure or air press to press-fiting bar, assemble laborsaving easily, can easily overcome huge
Axial force.
Beneficial effect: compared with prior art, it is an advantage of the invention that using fairlead as spacing, promotes by press-fiting bar
Circlip overcomes axial force to be assembled in workpiece, and circlip moves steadily, and assembly tooling simple in construction can be made by oneself, it is not necessary to
Dedicated elas-tic back-up ring fitting machine, cost-effective, easy to use, assembling process is convenient easily, remodels quickly.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate
The present invention rather than limit the scope of the present invention, after having read the present invention, each to the present invention of those skilled in the art
The amendment planting the equivalent form of value all falls within the application claims limited range.
As shown in accompanying drawing 1-5, the assembly tooling of a kind of circlip for hole, is U-shaped lead 1 and band including longitudinal section
Have annular boss 2 press-fits bar 3, and annular boss 2 will press-fit bar 3 and be divided into upper end 6 and lower end 7, lead 1 center to offer perforation 4,
Lead 1 is inverted and is made its U-shaped mouth downward, press-fits bar 3 and is inserted in lead 1 inside, and perforation 4 formation matched in clearance, ring are stretched in upper end 6
Shape boss 2 and diapire overlap joint in lead 1.Form tangent plane 5 along perforation 4 shift outward cut-out longitudinal to lead 1, will lead
Time above the workpiece hole 9 that post 1 is inverted on the workpiece 8 of circlip to be installed, tangent plane 5 and workpiece hole 9 is made to form mismatch 10.
Annular boss 2 diameter is slightly less than workpiece hole 9 diameter, to ensure that annular boss 2 and circlip 11 have the biggest
Contact area transmits steadily, in uniform way the axial force of applying.
The U-shaped mouth diameter of lead 1 is slightly less than workpiece hole 9 diameter, and circlip 11 can be made during assembling to enter work smoothly
In piece bores 9, prevent circlip 11 resilience from entering in U-shaped mouth simultaneously.
Press-fiting lower end 7 diameter center bore less than circlip 11 of bar 3, lower end 7 is formed with the bottom outlet 13 on workpiece 8
Matched in clearance.
Use the method that circlip for hole is assembled by assembly tooling of the present invention: be directed to post 1 inversion and make its U-shaped mouth
Downwards, will press-fit bar 3 and be inserted in lead 1 inside, the upper end 6 press-fiting bar 3 passes perforation 4, circlip 11 and pad 12 is overlapped
In the lower end 7 press-fiting bar 3, by being positioned over above the workpiece hole 9 of workpiece 8 together above, it is placed with spring 14 in workpiece hole 9, press-fits
The lower end 7 of bar 3 is stretched in spring 14, and circlip 11 and pad 12 are between spring 14 and annular boss 2, with lead 1
As spacing, according to the size of the power of spring 14, above lead 1, impose suitable axial force, annular boss to press-fiting bar 3
2 act on circlip 11 promotes it to overcome downwards spring force, observes circlip 11 by mismatch 10 simultaneously, uses Circlip tongs
Stretching into clamping circlip 11 in mismatch 10, auxiliary pushing circlip 11 overcomes downwards spring force, thus by circlip 11
In groove 15 in press-in workpiece 8, complete assembling.
Can by hydraulic pressure or air press to press-fit bar impose axial force with reach to assemble laborsaving easily.The height of lead
Degree and the length press-fiting bar pass through design, reach to make circlip be mounted directly in entrance groove.
