Abstract
The present invention relates to the sand mould structure that supercharger volute angle positioning master reference is extended to outer wall by inner chamber.Make core set up a flange face in exhaust gas intake port part by improving sand cores of castings structure to extend on the outside of exhaust flange air inlet, a technological datum face is set up in housing flange part, after moulding by casting, can be using fixed locator on clamping processing tool, to substitute original movable locator, casting flange face can smoothly be processed in clamped one time.Locator is not necessary to move when assembling and disassembling workpiece, and the reliability of locator is improved, and clamping workpiece number of times is reduced, and has been saved the time of clamping mobile locator, has been also improved positioning precision.
Description
Technical field
The present invention relates to changing for the original positioning datum of supercharger volute casting, particularly angle position location
Enter.
Background technology
The original positioning datum of volute casting of engine supercharger, the abroad company such as enterprise such as Honeywell
Product drawing on, there is specified location to feel relieved respectively, determine face and determine angle, be used as first road manufacturing procedure
Anchor point.The selection of the master reference anchor point of volute, the big feature of one is exactly all to select in inner chamber,
From casting analysis, these positions are all on the core of casting, because core is volute inner chamber volute
The determinant of runner and each control orifice position, shell is only control casting section thickness.But implementing clamping
During positioning, the structure of fixture is just extremely complex, especially angle positioning datum, typically all selects in volute
Exhaust gas intake port end close on the inwall of flange face, the angle locater on fixture can not be designed to fix
Formula because this can hinder installation of the casting on centralizer, casting must it is in place on centralizer after,
Angle locater is moved to inner chamber again, then contacts casting and angle locater, is also after process finishing
Angle locater is first removed, casting could be removed from fixture, but just because angle locater is from outer
Cast inner wall is goed deep into again by mobile link by portion, and it is on flange face top, that is, nothing to have many supporting members
Method is processed to exhaust gas intake port flange face again, it is necessary to install post-processing again, and this just brings angle to position
Device will often move that brought precision is unstable, in-convenience in use the accumulation of error with resetting.
The content of the invention
The purpose of the present invention is that the angle positioning master reference face of supercharger volute extends to outer wall by inner chamber
Sand mould structure.By changing the core mold and outer casing mold of casting, make the exhaust gas intake port of volute core
Part increases a Flange Plane.Flange shell position is extended to toward outer wall direction, in shell exhaust flange
Outer ledge increases the sand mold in a technological datum face, then chimeric with shell into an entirety, pours and builds up casting
After part, the facet of this outer wall is really integrally formed with inner chamber core, its positioning action and inwall
Master reference locating surface effect is consistent.
The technical scheme is that, the exhaust gas intake port flange top of core, core, which increases a flange, puts down
Face, Flange Plane extends to the position of the outer rim shell of exhaust gas intake port flange, under this Flange Plane
I.e. the outside of portion's exhaust flange, down increases the sand of an outer wall reference plane on the position of shell
Type, this position of shell reserves breach, and during combination sand mold, these increased positions are fitted together into shell
Original position, makes this reference plane sand mold and housing flange form entirety.
The distinguishing feature of the present invention is that the angle locater of Set and Positioning can when casting carries out machining
To use fixed form, it is not necessary to want move angle locator when mounting and dismounting workpiece, more can be one
Secondary install is processed in positioning to Flange Plane, it is to avoid the position error that secondary installing is brought, angle
Locator stability is strengthened, and assembly and disassembly workpiece is convenient to.
The angle master reference extension displacement of supercharger volute sand cores of castings, has obtained being permitted for foreign customers
It can be produced by improved sand mould structure.

Fig. 2 is Fig. 1 A-A section views.
In accompanying drawing：1st, core 2, exhaust gas intake port flange 3, outer wall reference plane sand mold

Embodiment
The angle master reference of supercharger volute is extended to the sand mould structure of outer wall by inner chamber.Change core 1
Mould, make core 1 exhaust gas intake port flange 2 top increase a Flange Plane sand mold 6, flange
Plane sand mold 6 extends to the position of external mold arenaceous shell 4 of the outer rim of exhaust gas intake port flange 2, in Flange Plane sand
The bottom of type 6, that is, exhaust gas intake port flange 2 outside, on the outer position of sand shell 4 increase by one
Outer wall reference plane sand mold 3, external mold arenaceous shell 4 is also improved, by the Flange Plane sand mold 6 of core 1 and outside
Wall reference plane sand mold 3 is all inlaid on the relevant position of exhaust gas intake port flange 2 of external mold arenaceous shell 4, shape
Into a sand mold entirety.
Claims (1)
1. supercharger volute angle positioning master reference is extended to the sand mould structure of outer wall by inner chamber, it is special
Levy and be：The exhaust gas intake port flange top of core increases a Flange Plane, and Flange Plane extends to row
The position of the outer rim shell of gas suction flange, i.e. in the outer of this Flange Plane bottom exhaust flange
Down increase the sand mold of an outer wall reference plane on the position of side original shell, this part of shell reserves scarce
Mouthful, the increase position of core is fitted together into shell, with shell one sand mold entirety of formation.
