Abstract
The disclosure provides a measurement device for measuring a work piece defining a first circular hole and a second circular hole. The measurement device includes a base, a location member fixed on the base, a fixing pin fixed on the location member, and a measuring pin slidably positioned on the location member. The fixing pin and the measuring pin are configured for being received in the first circular hole and the second circular hole of the work piece, respectively. A diameter of the measuring pin is substantially equal to a standard diameter of the second circular hole minus doubled tolerance. The distance between axes of the fixing pin and the measuring pin is substantially equal to a standard value of the distance between centers of the first and second circular holes of the work piece.
Claims20
A measurement device for measuring a work piece defining a first circular hole and a second circular hole, comprising:
- a base;
- a location member fixed on the base;
- a fixing pin fixed on the location member to be received in the first circular hole of the work piece;
- and
- a measuring pin slidably positioned on the location member to be received in the second circular hole of the work piece, wherein a diameter of the measuring pin is substantially equal to a standard diameter of the second circular hole minus two times a tolerance;
- wherein the distance between axes of the fixing pin and the measuring pin is substantially equal to a standard value of the distance between centers of the first circular hole and the second circular hole of the work piece.
A measurement device comprising:
- a base;
- a location member fixed on the base;
- a fixing pin fixed on the location member;
- and
- a measuring pin slidably positioned on the location member, wherein a diameter of the measuring pin is substantially equal to a standard diameter hole minus two times a tolerance;
- an orientation assembly comprising a pin aligned with the fixing pin on the location member,
- wherein the fixing pin comprises a main body and a receiving portion, the main body is fixed on the location member, and the receiving portion is substantially a cone;
- and the distance between axes of the fixing pin and the measuring pin is substantially equal to a standard value.
