Abstract
The utility model supercharger volute endoporus surface location special gauge and corrective gauge, are the qualitative cubings of the datum level and endoporus distance of curved surface for detecting volute, and the measuring point of former cubing is 90 ° of wedge angles, and easily blunt loses essence when using, and also easily scratches volute curved surface.90 ° of wedge angles of measurement point are now changed to the coning angle tangent with measurement of curved surface point, make sharp corner passivation, it is not easy to wear, increase the service life.Simultaneously curve probe and datum level are changed to be axially movable, installed in cubing dial gauge can direct reading error, no longer use comparative method for measuring with height gauge, cubing calibration can be zeroed on corrective gauge, simplify detection process.
Description
Technical field
The special gauge of machine-building supercharger volute processing endoporus surface location measurement.
Background technology
Engine supercharger volute casing endoporus curved surface is coordinated with the diametral surface of turbine, keeps each point gap uniformity on curved surface
And reach a kind of structure of dynamic sealing.The position of volute endoporus curved surface is mainly has precision to want with the turbine installation base surface of volute
Ask, this is the important indicator for ensureing booster power output.When volute endoporus surface location is detected, except using coordinate measuring machine
It is on a production line or a large amount of using the qualitative screening of special gauge outside sampling Detection.
According to supercharger volute foreign countries drawing position detect require, be with curved surface a bit, with certain away from installation base surface
The precision of distance is control range, that is, in the dimensional accuracy on diameter periphery as test point, will according to this technology
Ask, be made by the diameter face of cylinder of figure, the end face vertical with diameter, its circumferential edge is highly also made in 90 ° of sharp comer by figure
Into, volute endoporus is put into, then compare with the installation base surface of volute, draw the basal plane and distance of curved surface error of volute.
Special gauge first in this way level must be put on curved surface and is put, the circumference wedge angle of cubing easily scratches whirlpool
Shell curved surface, at the same wedge angle also easily blunt and can not use, secondly detection when add gauge outfit to measure the mistake of basal plane with height gauge
Difference, this and cubing also influence very big in the position of volute, and the circumference wedge angle of cubing slightly weares and teares, and cannot be continuing with.
The content of the invention
The purpose of this utility model is that the wedge angle of solution special gauge measurement point is easy to wear, and 90 ° of wedge angles are changed into obtuse angle is
Tangent with volute measurement of curved surface point, cylinder end face reforms into circular conical surface, and measurement point cubing is just extended as obtuse angle and uses the longevity
Life.Datum level table tool comparative measurement method is changed to datum level and is contacted with the benchmark of volute simultaneously, datum level and lower end measurement point
It is axially movable, it is just direct on table tool during measurement as long as making measurement point and datum level table tool on corrective gauge to zero
Reading error value.
The technical solution of the utility model is that the diameter of curve probe is made by volute drawing institute dimensioning, bent with volute
Some places of face contact are made the coning angle tangent with the point on curved surface, and curve probe top small column is surveyed installed in benchmark
In the centre bore in face, benchmark survey face top install dial gauge, table gauge head benchmark survey face in curve probe small column end face
Contact.
Corrective gauge is made of by datum level and measurement of curved surface the point range accuracy of volute.
Remarkable result of the present utility model is that the measurement point of former gauge head makes service life extension, volute curved surface behind obtuse angle into
It is difficult to be scratched by cubing gauge head wedge angle, after checking list tool is to zero on the corrective gauge, no longer with the more different height of height gauge when using
Degree, directly from the upper reading error of table tool can simplify detection process.

Specific embodiment
The external diameter of curve probe 1 is made by volute drawing, is made and curved surface phase tangent plane with some places of the curved face contact of volute 4
Into coning angle, the top small column of curve probe 1 be arranged on benchmark survey face 2 centre bore, benchmark survey the centre bore top of face 2 install
Dial gauge 3, the gauge head of dial gauge 3 benchmark survey face 2 centre bore in the small column end contact of curve probe 1.Corrective gauge 5 be by
The range accuracy of benchmark and the measurement of curved surface point of volute 4 is made.
