Fixture mandrel.
The technical solution realizing this utility model purpose is: spring quick-speed jigs mandrel, and its feature exists
In: include chuck body, for positioning, the supporting of workpiece end face is followed closely, at least three for swelling inner hole of workpiece
Disc spring film and for promote extruding disc spring film deformation guide pin bushing, described chuck body include connect
Portion, main part, swelling portion, guide part and threaded shank, described main part, swelling portion, guide part and screw rod
The external diameter in portion diminishes successively, and described supporting nail axial distribution is located in chuck body, and described guide pin bushing is slidably
Being sleeved on guide part, described disc spring film is sleeved in swelling portion, and described disc spring film is provided with some
The strip gab seam of radial equipartition, the opening direction of described strip gab seam is arranged alternately, in described threaded shank
It is provided with and extrudes the nut of disc spring film for promoting guide pin bushing to slide on guide part.
Described guide pin bushing is axially arranged with draw-in groove, and described guide part is provided with the card convex corresponding with draw-in groove.
Described card convex be provided with blind hole and blind hole by guide part in be provided with end and protrude the group of alignment pin of blind hole
Become.
Described alignment pin end is provided with screwed hole.
The osculum end of described disc spring film is towards main part, and big opening end is towards guide pin bushing.
When described disc spring film is some, disc spring film is that parallel sleeve stacks.
Described leading is provided with tabletting between portion and nut.
It is provided with pad between described main part and disc spring film.
Described supporting nail in chuck body the most uniform three.
Described connecting portion is provided with the installing hole being connected with lathe screw rod.
This utility model spring quick-speed jigs mandrel has the advantages that
1) disk spring flakiness shape, it is easy to formation molectron, practicable building block assembling and replacing, required
Space is little, uses, keeps in repair, changes conveniently.
2) it is provided with the strip gab seam of some radial equipartitions due to disc spring film, there is zero stiffness feature,
Transmit extruding force by guide pin bushing, make disc spring film produce compression displacement in swelling portion, make disc spring film
The most radially enlarged, produce stable, safe and reliable clamping force effect, work surface contact rate is high, it is achieved right
Axle sleeve or the gapless clamping of cone cover parts, and simple in construction, service life is long, and load is big, safety
Performance is high, dismantles efficient and convenient.
3) chuck body is provided with installing hole, can be installed on different grinding machines, and interchangeability is strong, installation side
Just, various occasion can be met use.
