ABSTRACT:
FIELD OF THE INVENTION
The present invention generally relates to an inspection gage. More particularly, the present invention relates to a gage assembly that is suitable for inspecting compliant molded dust boots and/or seals. The present invention also includes a method for forming such an assembly.
BACKGROUND OF THE INVENTION
Traditional methods for dimensionally inspecting injection or compression molded dust boots or seals can be complex, time-consuming, and inefficient.
There therefore exists a need in industry for an inspection gage that can be formed in a simple and versatile manner to provide reliable, efficient and cost effective inspection of molded components. There further exists a need for a gage that is capable of simulating the intended environment for the molded component being inspected.
SUMMARY OF THE INVENTION
The present invention recognizes the current need to simplify the dimensional and functional inspection analysis of flexibly compliant components, such as dust boots or seals. The invention further recognizes the limitations associated with traditional dimensional inspection methods for injection molded and/or compression molded components and the need for a means of providing practical “real time” performance analysis regarding the same.
The present invention provides a gage assembly that is capable of simulating the functional environment of a molded component and providing efficient, inexpensive, and real time performance testing in a production or laboratory environment.
In accordance with an embodiment of the invention, a gage assembly is provided that is suitable for inspecting a molded specimen. The assembly includes a gage body, a collar unit, and a mating boss adapter. The collar unit includes a collar that is adapted to be secured to the gage body and to secure a specimen. The collar unit also includes a stud having an upper portion and a lower portion, the stud being adapted to secure the specimen being inspected. A mating boss adapter is adapted to be installed over the collar unit to secure the specimen so that a portion of the collar unit and a portion of the mating boss adapter contact the specimen and simulate the intended functional environment of the specimen. A method for forming a gage assembly in accordance with the principles of the invention is also disclosed.
