Abstract

The invention relates to a detection device, in particular, a detection device for measuring the contour of a non-circular inner hole and a detection method. The detection device comprises a workbenchand a supporting frame fixed onto the workbench; the supporting frame is provided with a laser displacement sensor; the workbench is provided with a platform for carrying a part to be tested; positioning blocks used for clamping the part to be tested and arranged at two sides of the part to be tested are located above the platform; the positioning blocks comprise a first V-shaped positioning block and a second V-shaped positioning block which are slidably arranged on the workbench; the positioning blocks are connected with driving devices for driving the positioning blocks to move; the laserdisplacement sensor is located above the part to be tested; and at least one of the laser displacement sensor or the platform is rotatable. According to the detection device of the invention, laser oblique line projection measurement is adopted to measure the inner diameter of an ellipse, so that the radial length of the contour of the ellipse can be measured through indirect conversion, and failure to realize measurement which is caused by a condition that the laser displacement sensor is larger than the inner hole can be avoided.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device and a detection method for measuring the contour of a non-circular inner hole. Background technique [0002] In the processing and manufacturing industry, the processing of parts, whether it is the processing process or the quality and performance after processing, requires a lot of testing work. At present, tools such as through gauges, stop gauges, and vernier calipers are mainly used for the detection of process dimensions of non-circular inner hole parts, and manual detection is still the main method, and the detection efficiency is very low. Especially in the case of mass production of non-circular inner hole pistons, it is more necessary to quickly detect the contour accuracy of non-circular inner holes. Contents of the invention [0003] In order to solve the problem of low detection efficiency of non-circular inner holes in the prior art, the present invention p...
