Patent ID: 8898924

Claim:
A test device for testing whether a depth of a chamfer of a hole of an object is qualified or not, the test device comprising: a base comprising a block to be rested on the object and a positioning bar extending down from the block to abut a bottom end of the chamfer; an inserting member slidably mounted to the block along a direction parallel to an extension direction of the positioning bar, wherein a bottom end of the inserting member is operable to contact a slanted surface of the chamfer; and a test member slidably rested on the block, a bottom of the test member defining a first cutout extending through a front end surface of the test member, a front portion of a top wall bounding the first cutout defining a second cutout communicating with the first cutout and extending through the front end surface of the test member, wherein a depth of the second cutout equals a tolerance of the standard depth of the chamfer of the object, wherein the second cutout is operable of receiving an upper portion of the inserting member in response to the depth of the chamfer of the hole being qualified, the first cutout is operable of receiving the upper portion of the inserting member in response to the depth of the chamfer of the hole being greater than the maximal standard depth of the chamfer.
