Abstract
The invention provides a blade outline detecting device, which can solve the problem that when the blade outline on a blade assembly is detected by adopting three coordinate measuring machines, the detecting speed is slow and the efficiency is low. The blade outline detecting device comprises a bottom plate and is characterized by further comprising a positioning core rod and a detecting snap-gauge. The positioning core rod is fixed on the bottom plate through screws, the detecting snap-gauge is fixed on a support by tightly pressing nuts through a positioning pin and the snap-gauge, and the support is fixed on the bottom plate. the detecting snap-gauge detecting surface is identical to the theoretical molded surface of a blade to be detected, and the fact that a distance between the detecting surface and the theoretical molded surface is equal to a detection standard distance is ensured.
Description
Technical field
The present invention relates to blade profile profile tolerance pick-up unit field, especially a kind of blade profile degree pick-up unit that is applied to the impeller assembly of sewage disposal system is specially blade profile degree pick-up unit.
Background technology
A kind of impeller assembly that is used for sewage disposal system; It comprises impeller housing; Impeller housing outer peripheral face fixed blade, blade need detect the blade surface profile tolerance after being installed on impeller housing, and the blade surface profile tolerance detected and is mostly to carry out through three coordinate machine in the past; Because impeller assembly volume is bigger, adopts three coordinate machine to detect and have inconvenience, slow, the inefficient problem of detection speed of detecting.
Summary of the invention
To the problems referred to above, the invention provides blade profile degree pick-up unit, it can solve slow, the inefficient problem of detection speed that exists when adopting three coordinate machine that impeller assembly blade profile tolerance is detected.
Its technical scheme is such; It comprises base plate; It is characterized in that: it also comprises location mandril and detects clamp that in said base plate, said detection clamp is fixed in support through register pin and clamp gland nut to said location mandril through screw retention; Said support is fixed in said base plate, and the theoretical profile of said detection clamp detection faces and blade to be detected is consistent and guarantee that said detection faces equates with the detection reference distance with distance between the said theoretical profile.
It is further characterized in that: the periphery of said location mandril is provided with axial bond, and its upper end is provided with gland nut; Said rack side wall has L shaped groove, and said detection clamp is positioned said L shaped groove through register pin; The bottom of said detection clamp has U type groove, and said gland nut is fixed said detection clamp and said support through said U type groove; Said support is provided with three groups, and wherein every pack support comprises four said supports.
Adopt the present invention that the blade surface profile tolerance of impeller assembly is detected; Its beneficial effect is: its detection is quick and convenient; Only need the impeller housing of impeller assembly be set in location mandril and guarantee that the axial keyway of impeller housing reliably is connected with the key of location mandril; To detect clamp and be fixed in support, and detect the detection that distance between clamp and the blade profile to be detected can be accomplished the blade profile degree with clearance ruler, its detection speed is fast, efficient is high.
