Device for measuring height of face tooth

The utility model provides a measuring device which is suitable for height measurement of a face tooth. The device comprises a wedge block and a round bar, wherein the wedge block is provided with a bottom plane surface and a top inclined surface which form an included angel Beta; the included angle Beta is equal to the tilt angle of the face tooth of a face gear to be measured; and when the size of the diameter of the round bar is needed to meet the measurement requirement, at least one part of the round bar is clamped in a tooth socket of the face tooth to be measured and is tangent to two side tooth surfaces. The device has the main benefits as follows: (1) the structure is simple; the measurement is convenient; (2) the height of the finished face tooth can be repeatedly measured, so as to guarantee the qualification rate of products; (3) the height of the face tooth can be measured during the processing process, and working allowance can be calculated, so as to provide convenience for feed adjustment; (4)
