Embodiment Construction

[0016] The details and working conditions of the specific device proposed according to the present invention will be described below in conjunction with the accompanying drawings.

[0017] The device is composed of a hexagonal flange nut 1 , a measuring column 2 and a detection sleeve 3 , the hexagonal flange nut 1 cooperates with the threaded column 21 ; the detection sleeve 3 cooperates with the detection column 24 .

[0018] Measuring column 2 includes threaded column 21, cone 22, cylinder 23, detection column 24 and guide cone 25 five parts; threaded column 21 is on the left side of cone 22, cylinder 23 is on the right side of cone 22, and detection column 24 is on the right side of the cylinder 23, and the guide cone 25 is on the right side of the detection column 24.

[0019] The diameter of the inner hole of the detection sleeve 3 is ΦA, and the tolerance is (0, +0.003) mm; the runout of the outer cone surface relative to the central axis of the inner hole is 0.005 mm.

Abstract

The invention provides a coaxility testing tool which is composed of a hexagonal flange nut, a measuring column and a testing sleeve. In use, a conical part on the measuring column matches a conical hole of a tested workpiece. The hexagonal flange nut matches a threaded column on the measuring column. The measuring column is fixed on the workpiece. The inner hole of the testing sleeve matches the measuring column so that the conical surface of the testing sleeve contacts with the opening of a phiE hole on the workpiece. Whether the whole conical surface uniformly contacts with the opening of the phiE hole is observed; if yes, qualification of the tested coaxiality is determined, and otherwise, unqualification of the tested coaxility is determined. The coaxility testing tool can test coaxility of a straight hole on the tested workpiece relative to axis of the conical hole in use. Furthermore the coaxility testing tool has advantages of simple structure, high testing precision, safe and stable performance, low manufacturing cost, etc.
