Description

TECHNICAL FIELD

[0001] The utility model belongs to an anastomat holder production technical field, and particularly relates to an electric anastomat holder gauge. BACKGROUND

[0002] After anastomat holder production is completed, due to cooperation of the front end of the holder and a pipe, in order to ensure that the pipe can be normally installed and connected, the thickness of the bottom surface of the front end of the holder needs to be detected. The existing detection method generally adopts three-coordinate measurement or projector measurement. In the three-coordinate measurement method, a dial gauge is used to take two symmetrical points on the rear circumference of the front end of the holder, and then a third point is taken on the bottom surface of the front end of the holder. Since the bottom surface of the front end of the holder is processed by a milling cutter, the dial gauge error is large due to the influence of the plane roughness. In the projector measurement method, since the arc-shaped structure of the front end of the holder is discontinuous in the middle, the maximum value cannot be measured after projection, and the chamfer value also cannot be measured, and only an approximate value of the size of the bottom surface of the front end of the holder can be calculated, and the error is also large. Therefore, it is a problem to be solved to design a tool for conveniently and quickly detecting the thickness of the bottom surface of the front end of the holder.
