The utility model discloses a detect utensil of examining of spare part, including examining a casing, round pin axle and base platform for whether length, the symmetry of drilling, the straightness that hangs down of detecting spare part drilling distance ring flange are qualified.

The gauge housing includes two aligned apertures and an interior cavity, preferably square.

The diameter of the pin shaft is smaller than the diameters of two aligned holes of the gauge shell and the drilled holes of the parts.

The base platform is used for supporting the whole device and is fixedly connected with the detection tool shell.

Preferably, examine a still including the locating piece, the spare part can be fixed to the locating piece, prevents that the spare part from rocking, examines and be equipped with the slot that can supply the locating piece to insert and reciprocate on the casing of utensil, the inside opening chute that forms of locating piece, the relative central axis symmetry of chute, the opening chute is trapezoidal or toper, more is favorable to fixed spare part.

After one end of the part with the drill hole is inserted into the inner cavity of the detection tool shell, the flange plate of the part is abutted to the reference surface on one side of the inlet of the inner cavity of the detection tool shell, and one end of the part with the drill hole is in close contact with the inner cavity of the detection tool shell. And rotating the part to connect the two aligned holes of the detection tool shell and the part drilling hole into a line, and if the pin shaft can penetrate the two aligned holes of the detection tool shell and the part drilling hole, the distance between the drilling hole of the part and the flange plate is proved to be qualified, and the symmetry and the verticality of the drilling hole are proved to be qualified.

The utility model discloses whether the drilling position that can accurately detect spare part fast is accurate, other measurement methods relatively, the utility model discloses simplify detection achievement greatly, reduced personnel's intensity of labour, improved labor efficiency, still greatly reduced simultaneously the human factor to the influence that detects, the reliability has very big improvement, and the testing result is highly credible, and the probability of erroneous judgement falls to lower level.

The sizes of all the components of the checking fixture can be adjusted to meet the detection requirements of different parts.
