Description
Technical field
The utility model is related to a kind of test measuring devices, and in particular to a kind of hole in piece part test measuring device belongs to automobile making skill
Art field.
Background technology
Currently, detection axial workpiece internal diameter usually uses the inner measuring jaw of vernier caliper as general measurer, vernier caliper is used
Part is detected, measurement error varies with each individual, less efficient, and measurement error is related with inner measuring jaw length, and inner measuring jaw length is longer, surveys
It is bigger to measure error；Inner measuring jaw length is longer, and width is also bigger, and the difficulty for measuring deep and small hole type parts internal diameter is bigger.For solution
Certainly this problem in automobile manufacture industry and mechanical processing industry, generally uses drift, stops for the part of batch production
The special measuring tools such as rule measure deep and small hole type parts internal diameter, and indeformable or very little deforms after its interior hole machined of metal parts, measures
Drift and no-go gage used in hole size use circular cross-section, comparison to have using the general measurer of inside micrometer efficient, fast
Spend the features such as fast.
But punching press and injection-moulded plastic part are irregular due to deforming its internal via shape, it cannot be measured with circular cross-section no-go gage
Maximum hole size, and when measuring punching press and injection-moulded plastic part, Aleuroglyphus ovatus ability is poor.
Therefore, a kind of hole in piece part test measuring device easy to use of development is very important, and the hole in piece part detection limit
Tool also has important application prospect.
