Description
Technical field
The utility model belongs to application techniques field, more particularly to a kind of for hub centre hole and the integral type of flange face
Spray protective tooling.
Background technology
Automobile aluminum wheel hub big deduction cap wheel-type spraying standard be centre bore and flange face without powder without paint, existing wheel hub is in application
When, the centre bore of wheel hub is unlimited, and centre bore can be sprayed to by so dusting, and the powder of centre bore is removed with the mode for blowing powder
When, remaining powder is splashed to the back side mounting surface in wheel hub hub portion from hub centre hole, for general wheel hub purchaser, installs
Face glues powder and is subjected to or is solved by polishing on a small quantity, but comes for pursuing excellent handling or high required precision high-end vehicle
Say, powder or polishing are glued in mounting disc can influence the flatness of mounting surface so as to reduce the real contact area of mounting surface and axletree,
So as to influence handling, for example, steering is caused to perform delayed etc..
The existing frock that protective coating is carried out to hub centre hole is to cover protective plate at hub centre hole mostly, is treated
Protective plate is removed after the completion of spraying, a procedure is so added, the efficiency of production line is reduced.
In addition, additionally providing a kind of split type spraying protective tooling in the prior art, protection will be tied respectively when dusting
Structure is covered on cap seam and stretched in centre bore, the two is protected respectively, although can play certain protective effect,
But powder and paint can flow into centre bore by shade gap or stick in two kinds of safeguard structure separation, spraying process
Protected at shade and not to flange face, not only have a strong impact on product coating quality, and two kinds of safeguard structure frock costs
It is high.
Utility model content
The deficiencies in the prior art in view of the above, the purpose of this utility model, which is to provide, a kind of is used for hub centre hole
Protective tooling is sprayed with the integral type of flange face, prevents powder and paint from entering centre bore by equipotential principle and masking mode
And flange face.Aluminium alloy wheel hub centre bore and flange are effectively realized without powder without paint, demand of the high-end customer to product is met, and
And reduction protection cost.
To achieve the above object, technical solutions of the utility model are as follows：
A kind of integral type spraying protective tooling for hub centre hole and flange face is provided, it includes stretching into hub centre
The protection post in hole and the protective plate for blocking wheelboss flange face, the protection post fits with hub centre hole, and is not less than wheel hub
Centre bore, the protective plate is connected to the bottom of the protection post, and integral structure, and the protection are formed with the protection post
The external diameter of disk is not less than the size in wheelboss flange face.
Preferably, diameter small 0.5-3 mm of the external diameter of the protection post than hub centre hole.
Preferably, height high 0.5-2 mm of the height of the protection post than hub centre hole.
Preferably, the protection post and the protective plate are fixed together by welding manner.
Preferably, the protection post and the protective plate are integral type structure by casting.
Preferably, the diameter of the protective plate is more than the diameter in wheelboss flange face.
Preferably, being provided with the circumferential projection along the protective plate at the outer rim of the protective plate.
The beneficial effects of the utility model are：Protection post is stretched into hub centre hole, and the inner surface in hub centre hole is made
Protection, prevents powder and paint from entering in centre bore, protective plate blocks wheelboss flange face, prevents powder and paint from flying to flange face
On, and protection post and protective plate are integral structures, are easy to process and install.
Brief description of the drawings
Fig. 1 is the section view that protective tooling is sprayed according to the integral type of the present utility model for hub centre hole and flange face
Figure；
Fig. 2 is the top view that the integral type for being used for hub centre hole and flange face in Fig. 1 sprays protective tooling.
Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages of the present utility model and effect easily.
Fig. 1 is the section view that protective tooling is sprayed according to the integral type of the present utility model for hub centre hole and flange face
Figure.Fig. 2 sprays the top view of protective tooling for the integral type for hub centre hole and flange face in Fig. 1.Such as Fig. 1 and Fig. 2
Shown, the integral type spraying protective tooling for hub centre hole and flange face includes protection post 1 and protective plate 2, and protective plate 2 connects
The bottom of protection post 1 is connected to, with protection post formation integral structure.In use, protection post 1 is stretched into hub centre hole, with
Hub centre hole is fitted, and is not less than hub centre hole, and the inner surface in hub centre hole is protected, powder and oil is prevented
Paint is sticked on hub centre hole.Protective plate 2 blocks wheelboss flange face, and the external diameter of the protective plate is not less than wheelboss flange face
Size so that powder and paint will not fly on wheelboss flange face.When in use, integral type spraying protective tooling is enclosed on spray
Applying is used for the sleeve of supporting wheel hub on streamline, protection post stretches into hub centre hole and wheel hub can also be played the role of positioning.
Preferably, the external diameter of protection post 1 is slightly less than the diameter in hub centre hole, and the preferably diameter than hub centre hole is small
0.5-3 mm.This is easy to protection post to enter hub centre hole, while being easy to wheel hub to depart from from integral type spraying protective tooling.It is anti-
Small―gap suture between guard post and outer wall and hub centre hole can form equipotential, be used by equipotential principle formation electrostatic screen
Fly into centre bore gap in preventing powder from protection column outer wall and produce dust cloud.
Preferably, the height of protection post 1 is slightly above the height in hub centre hole, and the preferably height than hub centre hole is high
0.5-2 mm.This is because, height of the protection post beyond hub centre hole can influence the surface around hub centre hole too much
Spraying.
Alternatively, protection post 1 and protective plate 2 can be molded as one formula structure by modes such as welding, casting, injections.
Preferably, the diameter of protective plate 2 is more than the diameter in wheelboss flange face, so as to wheelboss flange face edge is covered,
Preferably wheelboss flange face edge is protected.
Preferably, the circumferential projection along the protective plate is provided with the outer rim of protective plate 2.When wheel hub and integral type application are prevented
Nurse's assembling is closed in use, the circumferential projection on protective plate 2 can somewhat encase flange face, plays positioning wheel hub.
Preferably, the surface of protective plate 2 is smooth surface, is fitted with the flange face of wheel hub.
After the completion of spraying, wheel hub departs from from integral type spraying protective tooling, and the protective tooling can be maintained at
On spray-painting production line, it is continuing with.
Any person skilled in the art all can be without prejudice under spirit and scope of the present utility model, to above-described embodiment
Carry out modifications and changes.Therefore, such as those of ordinary skill in the art without departing from disclosed in the utility model
Spirit and all equivalent modifications for being completed under technological thought or change, should be contained by claim of the present utility model
Lid.
