Abstract
The utility model discloses a kind of Contiuum type bobbin covers, belong to spindle component technology field.The utility model is without bonding bobbin cover shell and stationary disk by adhesive, so as to avoid the defect being not fixed firmly due to adhesive.Tapered side is arranged in the lower section portion of bobbin cover shell, the lower section portion of magnet steel seat by the utility model, so as to prevent the mismachining tolerance of accessory from can will also carry out firm fitting between component, so as to reduce windage and dust accumulation.
Description
Technical field
The utility model belongs to spindle component technology field, is especially covered with pass with a kind of Contiuum type bobbin.
Background technique
Bobbin cover in existing spindle is formed by stationary disk, magnet steel seat, four part of bobbin cover shell, and is needed to use adhesive
Stationary disk is fixed on bobbin cover shell, leads to have following disadvantage:
1, adhesive failure, retainer are loosened, are loosened in bobbin cover shell so as to cause magnet steel；
2, inevitably there is mismachining tolerance in bobbin cover shell, stationary disk, and bobbin cover shell, stationary disk are easy to exist after fitting
Gap is easily accessible broken thread in gap so that wharve broken thread in rotary course is wound into spindle blade component, influence plus
Work efficiency rate.
Utility model content
Above-mentioned background technique there are aiming at the problem that, the utility model is intended to provide a kind of Contiuum type bobbin cover.
For this purpose, the utility model use following technical scheme: a kind of Contiuum type bobbin cover, including stationary disk, magnet steel seat and
Bobbin cover shell, characterized in that the bobbin cover shell includes cylinder ring portion and tapered portion, and cylinder ring portion is fixedly connected on cone
The top in shape portion, the bottom surface of tapered portion form the mounting plane for installing the magnet steel seat, and the magnet steel seat is placed in
In the inner cavity that the bobbin cover interior of shell is formed, the side in the lower section portion of the magnet steel seat and the bobbin cover shell
The side of tapered portion recline cooperation, the bottom surface of the bottom surface of magnet steel seat and the tapered portion reclines cooperation；
The stationary disk includes taper opening portion and the cylindrical portion for being set to taper opening portion center, the taper
Annular shoulder with the outer edge of the bobbin cover shell is formed on the top in open portion, and the bottom of bobbin cover shell passes through the ring
For shape shoulder against limit, annular shoulder is provided with multiple installation positions, and vertical threaded hole is provided on installation position, corresponding vertical
The bottom surface of the magnet steel seat and bobbin cover shell is provided with screwing through hole at the position of threaded hole, and screw protrudes into screw and passes through admittedly
Surely it is tightened against in threaded hole, is fixedly connected with stationary disk, magnet steel seat with bobbin cover shell by screw；The top of the cylindrical portion
The central through hole for being set to the bottom surface of magnet steel seat and bobbin cover shell is stretched out in portion.
As supplement to above-mentioned technical proposal and perfect, the utility model further includes following technical characteristic.
It is curved arc-shaped at the top outer rim of the bobbin cover shell, to avoid entering after at bobbin cover shell
The yarn of through-hole at the top of spindle blade is separated by bobbin cover shell.
The utility model can achieve following the utility model has the advantages that 1, the utility model is not necessarily to through adhesive to bobbin cover shell
It is bonded with stationary disk, so as to avoid the defect being not fixed firmly due to adhesive.2, the utility model is by bobbin cover shell
Lower section portion, tapered side is arranged in the lower section portion of magnet steel seat, so as to prevent the mismachining tolerance of accessory also can by component it
Between carry out firm fitting, so as to reduce windage and dust accumulation.
