Abstract
The invention discloses the assemble method of a kind of holdback, described holdback includes inner sleeve, roller assembly, described inner sleeve has flange, described roller assembly includes retainer, cam, camshaft and torsion spring, described cam is arranged on described retainer by camshaft, described torsion spring set is contained on described camshaft, it is characterized in that first being enclosed within by described roller assembly described in put, its cam is placed in described inner sleeve upper flange and is formed on cascaded surface, then quick rotation inner sleeve, described cam moment is deflected, after the deflection of described cam, described roller assembly has bigger assembling aperture, after the deadweight relying on roller assembly is slided, roller assembly is just sleeved on the flange of described inner sleeve.This assemble method of the present invention, for large-scale holdback, it is possible to puts in being quickly sleeved on by roller assembly, has simple to operate, the feature that packaging efficiency is high.
Description
Technical field
The present invention relates to a kind of holdback, particularly relate to the assemble method of holdback.
Background technology
Holdback generally comprises inner sleeve and roller assembly, and wherein inner sleeve has flange, and roller assembly is enclosed within the flange of inner sleeve
On, overcoat is enclosed within roller assembly, and described roller assembly includes retainer, roller, stud, cam and torsion spring, and retainer is distributed
In both sides, roller, stud are attached, described retainer are provided with corresponding roller hole, stud bolt hole and cam and install
Hole, torsion spring set is contained on the installation axle of cam.The holdback of current this structure, will assemble with inner sleeve set of rollers
Time, when remaining static under the effect of torsion spring due to cam, inside the convex surface deflection of cam, cause roller assembly to assemble
Aperture is reduced, and therefore, when assembling, after first set of rollers being put in being enclosed within, the fraction of its cam is by inner sleeve upper flange shape
The step surface become withstands, and wants on the flange being sleeved on inner sleeve set of rollers, needs manual by the cam rotation of roller assembly, make
Obtain roller assembly and form bigger group of aperture.This assemble method is for small-sized holdback, owing to its cam number is less,
When manual rotation's cam, as long as several both hands are the most permissible；But for large-scale holdback, owing to cam number is many, need
Want substantial amounts of manually to be rotated by cam simultaneously, form bigger assembling aperture.This is for the enterprise of current automated production,
Cannot realize, because the workman of enterprise of automated production own is less, and this assembling mode efficiency is the lowest, the most not
Adapt to the needs of modern production.
Summary of the invention
The deficiency existed in view of background technology, the problem to be solved in the present invention is to provide one can improve holdback assembling
The holdback assemble method of efficiency.
Realizing in the following way for this present invention: the assemble method of a kind of holdback, described holdback includes
Inner sleeve, roller assembly, described inner sleeve has flange, and described roller assembly includes retainer, cam, camshaft and torsion spring, described
Cam is arranged on described retainer by camshaft, and described torsion spring set is contained on described camshaft, it is characterised in that first will
Described roller assembly be enclosed within described in put, its cam is placed in described inner sleeve upper flange and is formed on cascaded surface, then quick rotation
Inner sleeve so that described cam moment deflects, after the deflection of described cam, described roller assembly has bigger assembling aperture, relies on
After the deadweight of roller assembly is slided, roller assembly is just sleeved on the flange of described inner sleeve.
The lower end of described inner sleeve is provided with bearing.
In the present invention, after inner sleeve quick rotation, due to the rubbing action of inner sleeve Yu cam, cam moment deflects so that
Roller assembly forms bigger assembling aperture, relies on the deadweight of roller assembly the most automatically to slide at the flange of inner sleeve so that it is suit
On flange, have and assemble advantage quickly and easily, be very suitable for large-scale holdback and assemble.
Accompanying drawing explanation
The relevant details of the present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is to put in roller assembly is enclosed within by the present invention to be formed, by flange, the state diagram that ladder withstands；
Fig. 2 is the state diagram after roller assembly is enclosed within inner sleeve flange by the present invention.
Detailed description of the invention
Referring to the drawings, the assemble method of this holdback, described holdback includes inner sleeve 2, roller assembly, described inner sleeve 2
Having flange 6, described roller assembly includes that retainer 1, cam 5, camshaft 3 and torsion spring 4, described cam 5 are pacified by camshaft 3
Being contained on described retainer 1, described torsion spring 4 is sleeved on described camshaft 3, during assembling, is first enclosed within by described roller assembly
In described inner sleeve 2, owing to cam 5 remains static, the assembling aperture of its roller assembly is relatively small, but is just enclosed within inner sleeve
On the body of 2, its cam 5 is placed in described inner sleeve 2 upper flange 6 and is formed on cascaded surface simultaneously, i.e. the very small part of cam 5 is convex
The cascaded surface that edge 6 is formed withstands, and installs a spanner in inner sleeve 2, and the lower end of this holdback inner sleeve 2 is provided with bearing 7, by axle
Hold the effect of 7, pull spanner quick rotation inner sleeve 2, when accelerating to rotate so that described cam 5 moment under the influence of centrifugal force
Deflection, after the deflection of described cam 5, described roller assembly just has bigger assembling aperture, relies on the deadweight of roller assembly to slide
After, roller assembly is just sleeved on the flange 6 of described inner sleeve 2.This assemble method, it is not necessary to by bigger artificial, one
Workman just can complete to assemble, and has feature easily and fast, is highly suitable for the assembling of large-scale holdback.
Claims (2)
1. an assemble method for holdback, described holdback includes inner sleeve, roller assembly, and described inner sleeve has flange, described
Roller assembly includes retainer, cam, camshaft and torsion spring, and described cam is arranged on described retainer by camshaft, institute
State torsion spring set to be contained on described camshaft, it is characterised in that first described roller assembly is enclosed within described in put, its cam is put
Formed on cascaded surface in described inner sleeve upper flange, then quick rotation inner sleeve so that described cam moment deflects, and described cam is inclined
After Zhuaning, described roller assembly has bigger assembling aperture, and after relying on the deadweight of roller assembly to slide, roller assembly is just sleeved on
On the flange of described inner sleeve.
The assemble method of holdback the most according to claim 1, it is characterised in that the lower end of described inner sleeve is provided with bearing.
