Abstract

The invention provides a conduit expanding part arc radius detection device, and belongs to the technical field of test and measurement. The conduit expanding part arc radius detection device comprises a workpiece locating base and a detection sample plate. The workpiece locating base is provided with a workpiece locating mechanism and a sample plate guiding mechanism. The workpiece locating mechanism is an inverted V-shaped groove of which the opening is downward. The sample plate guiding mechanism is a slide groove hole which is arranged on the workpiece locating mechanism. The central locating surface of the slide groove hole is overlapped with the central locating surface of the V-shaped groove. The detection sample plate is assembled in the slide groove hole. The detection sample plate has an inverted T-shaped structure and is provided with a guiding handle and a pressing plate which are mutually perpendicular. The guiding handle penetrates into the slide groove hole of the workpiece locating base. The bottom surface of the pressing plate is provided with a detection cutting edge which is matched with the axial cross section external contour dimension of the standard conduit workpiece expanding part. Radial locating of the detected conduit can be realized so that the arc curve of the detection sample plate and the central axis of the detected conduit are ensured to be in the same plane, and the reliability of the detection result can be enhanced.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the arc radius of the flaring part of a gas path or a liquid path conduit in precision equipment, and belongs to the technical field of testing and measurement. Background technique [0002] as attached figure 1 As shown, a conduit 1 used in the air or liquid circuit of precision equipment is provided with a conical flared mouth 1-1 at the end of the conduit 1, and the radius of the arc at the connection between the flared conical surface and the straight pipe is ( Hereinafter referred to as the arc radius of the flaring part) is R, in order to ensure the sealing performance of the gas path or liquid path in the precision equipment, the arc radius R of the flaring part of the conduit 1 needs to be tested before installation. [0003] In the prior art, for the detection of the arc radius R of the above-mentioned catheter flaring part, the method of light transmission t...
