Abstract
The utility model relates to an utensil is examined in combination of booster volute hole curved surface position examines the utensil by location axle, annular blade gauge head with measure the end cover and forms, by the screw of handle tip with whole of each unit construction one -tenth. The former utensil of examining is for integral, in case the gauge head blade has wearing and tearing to scrap slightly, the loss is very big. And originally examine the utensil and when the blade of gauge head weares and teares, can pull down the change, the gauge head more changed is coping used repeatedly more again also to carbide welds in the department at the blade, thereby it examines a part life to reach the extension, reduces the consumption cost of examining the utensil.
Description
Technical field
Machining detects volute endoporus curved surface and reference range position, a kind of combined cubing.
Background technology
The energy-saving and emission-reduction important device exhaust-driven turbo-charger exhaust-gas turbo charger of internal combustion engine, in volute, endoporus curved surface is identical with the spoon of blade shape of turbine, forms mutually clearance sealing structure, is to ensure that the key structure of engine exhaust utilization rate.In order to keep uniform gap with volute curved surface after making turbine assembling, when assembling, the axial required precision of turbine and volute is the highest.Volute is to take a bit (really one annulus) on curved surface adding on-line checking in man-hour, from this point to the distance of volute end face datum clamp face " A ", as the element to be measured of on-line checking, and curved surface profile is to be formed by program, periodically with coordinate measuring machine sampling detection.
This cubing is a stairstepping cylinder having two kinds of diameters, blade shape is made for detecting a bit on curved surface in the edge of major diameter, this point position is made up of diameter " B " and axial distance " C ", minor diameter is used for volute Internal hole positioning, in major diameter other end as measuring surface, with centimeter check end face and volute datum level " A " etc. high level error.In use the outer rim end points of cubing major diameter makes the cutting edge of 90 ° of angles, in addition the weight of cubing own is more easy to make angle wear and tear. and this cutting edge cannot be continuing with because of slightly abrasion, although thermally treated hardening, life-span is the shortest, just losing as long as slightly wearing and tearing that positioning action abandons need not, the cubing the most more renewed, so cubing learies is relatively big, also have impact on the user credibility to this cubing.
Summary of the invention
This utility model is the combined detection tool of a kind of supercharger volute surface location.Cubing uses fabricated structure, makes the detection cutting edge easy to wear can be with dismounting and change or maintenance, but still it is constant to be held in position precision.The distance endface position of detection keeps constant, and cutting edge parts can make more than one piece in advance, in case changing, but when maintenance cutting edge parts reach some, can concentrate grinding non-uniform thickness again, so that it may reuse a replacement cycle again.
The technical solution of the utility model is, the combined detection tool of a kind of supercharger volute surface location.
Installing annular cutting edge gauge head on the conical surface of locating shaft, gauge head top is set with detection end cap on locating shaft, has handle to stretch into and threaded with locating shaft in detection end cap mider hole, locating shaft cutting edge gauge head and detection end cap is connected.Annular cutting edge gauge head circumferentially trisection posistion is welded with hard alloy cutting edge.
The beneficial effects of the utility model are to be welded with hard alloy cutting edge by trisection on annular cutting edge gauge head easy to wear, enhance wearability, annular cutting edge gauge head can pull down replacing, scrap without cubing entirety, locating shaft and measure end cap and can retain and be continuing with, hollow form is made at the solid positions such as locating shaft, alleviate the weight of cubing, too increase the abrasion resistance of annular cutting edge, annular cutting edge gauge head can also be further continued for using through reconditioning, this just substantially prolongs cubing service life, reduces manufacture and the consuming cost of cubing.

Accompanying drawing illustrates: 1, locating shaft；2, annular cutting edge gauge head；3, hard alloy cutting edge；4, detection end cap；5, handle；6, tested volute；7, volute endoporus curved surface.
Detailed description of the invention
A kind of combined detection tool of supercharger volute endoporus curved surface, on the taper seat of locating shaft 1, annular cutting edge gauge head 2 is installed, annular cutting edge gauge head 2 is welded with hard alloy cutting edge 3 in cutting edge position circumferentially trisection, the top suit detection end cap 4 of locating shaft 1, handle 5 is threadeded with locating shaft 1 by the hole of detection end cap 4, will detect end cap 4, and annular cutting edge gauge head 2 and locating shaft 1 are connected.
Claims (2)
1. the combined detection tool of a supercharger volute endoporus surface location, it is characterized in that: annular cutting edge gauge head is installed on the taper seat of locating shaft, annular cutting edge gauge head top has detection end cap to be sleeved on locating shaft, handle is threadeded with locating shaft by detection end cap, detection end cap, annular cutting edge gauge head and locating shaft is connected.
The combined detection tool of a kind of supercharger volute endoporus surface location the most according to claim 1, is characterized in that: the cutting edge position circumferentially trisection at annular cutting edge gauge head is welded with hard alloy cutting edge.
