Description

TECHNICAL FIELD

[0001] The utility model relates to a roundness contour detection tool technical field, and specifically is a kind of roundness contour detection tool. BACKGROUND

[0002] In the hardware workpiece processing industry, various shapes of parts will often appear, including arc or circular workpieces, and in order to ensure that the workpiece with circular contour can be accurately applied to the installation instrument, the formed workpiece needs to be detected.

[0003] A patent with publication number CN208671890U discloses a gauge for detecting the roundness contour of a part. The gauge mainly comprises a base, a support plate, a positioning plate arranged on the support plate, and two measuring heads arranged symmetrically on the positioning plate. The positioning plate has a guide opening for cooperating with the sliding of the measured part. The guide opening includes a sliding-in area and a positioning area connected to the sliding-in area. The width of the positioning area gradually decreases in the direction of the measured part sliding from the positioning area to the sliding-in area. At least part of the positioning area is a relatively inclined groove surface for simultaneously fitting the contour surface of the outer contour of the measured part. At least part of the measuring head is exposed from the guide opening and is pressed and moved by the contour surface before the contour surface of the measured part is tightly fitted with the groove surface.
