Abstract

The utility model provides a surface profile tolerance detection mechanism with which the surface profile tolerance can be quickly and accurately detected, and the requirement of production line quality detection is satisfied. The detection mechanism comprises a bottom plate, wherein the lower end of the bottom plate is firmly fixed with supporting feet. The detection mechanism is characterized in that a center positioning structure ad a periphery positioning structure are arranged above the bottom plate; go and no-go gauge detection devices are disposed at corresponding positions of a to-be-detected profile surface of a part; the center positioning structure specifically comprises a core spindle and an expansion sleeve; the core spindle is firmly fixed on the upper end surface of the bottom plate through a bolt; the expansion sleeve is sleeved on the core spindle; the outer rim surface of the expansion sleeve is provided with a outer convex member; the to-be-detected part is sleeved in the expansion sleeve; the periphery positioning structure specifically comprises a positioning plate and a positioning pin; each go and no-go gauge detection device specifically comprises a positioning vertical column, a handle, a sliding block, a go gauge and a no-go gauge; the positioning vertical column is firmly fixed above the bottom plate; and the inside of the positioning vertical column is provided with a guide rail.

Description

A kind of surface profile testing agency

Technical field

The detection architecture technical field of the utility model involvement aspect profile is specially a kind of surface profile testing agency.

Background technology

Existing surface profile normal operation be that CMM three-dimensional instrument detects, although major part is detected part can both be detected accurately, but detection speed is slow, efficient is low, just relative effect for some production in enormous quantities or facet detection is limited to very much, not only checkability is low, and test range is wideless, and data are not accurate enough.Be difficult to satisfy production line quality inspection demand.

Summary of the invention

For the problems referred to above, the utility model provides a kind of surface profile testing agency, and it can satisfy quick and precisely checks out surface profile, satisfies production line quality inspection demand.

A kind of surface profile testing agency, its technical scheme is such: it comprises base plate, the lower end of described base plate is fastened with leg, it is characterized in that: the top of described base plate is provided with center location structure, location structure all around, its contoured surface correspondence position that comprises that also part need detect is provided with the go-no go gauge cubing, described center location structure specifically comprises mandrel, expansion set, described mandrel is by the upper surface of bolted in described base plate, described expansion set is set in described mandrel, described expansion set outer edge surface mating parts is provided with outer male member, described part to be detected is set in described expansion set, location structure specifically comprises location-plate around described, register pin, each described go-no go gauge cubing specifically comprises positioning vertical column, handle, slide block, drift, no-go gage, described positioning vertical column is anchored on the top of described base plate, have guide rail in the described positioning vertical column, described slide block is positioned at described guide rail, described slide block is equipped with described handle away from an end of described part to be detected, described slide block is provided with drift near an end of described part to be detected, no-go gage, described drift is positioned at the outside of described no-go gage, described drift, the contoured surface of no-go gage is towards the contoured surface of part to be detected.

After adopting the utility model, during detection after part is fixing, by drift and the no-go gage of handle promotion at its front end, be inserted in the contoured surface of part to be detected, then judge whether that according to the situation that pushes no-go gage leads to or drift ends, thereby the judgement surface profile, it can satisfy quick and precisely checks out surface profile, satisfies production line quality inspection demand.
