Part cracking inspection device

Abstract

The invention discloses a part cracking inspection device. The device comprises a supporting mechanism used for supporting and fixing parts, a detection mechanism used for providing pressure stabilizing gas, a detection tool used for receiving the parts and forming a closed space, and a fixing mechanism used for fixing the parts. The detection mechanism, the detection tool and the fixing mechanismare supported and detected by the supporting mechanism. The detection mechanism inflates and measures pressure during detection. The detection tool clamps the parts, and then the fixing mechanism presses the parts on a top of the detection tool. A relatively closed space is formed between the parts and the tool, whether gas leakage exists in the space or not is judged through inflation, pressuremaintenance and measurement by the detection mechanism, and therefore, the detection of cracks of the parts is achieved. The device has the advantages of high applicability and high detection efficiency, and the lag of a production schedule caused by product replacement is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of parts detection application, in particular to a part cracking inspection device. Background technique [0002] With the development of the economy and the progress of society, in the production of large-scale precision stamping processing, precision stamping parts have higher quality requirements. Stamping parts may crack under the action of pressure during processing. These cracked parts are unqualified. Products cannot enter the market. [0003] The existing cracking defects of stamping parts rely on naked eye detection or high-definition camera scanning test. The efficiency of high-definition camera scanning test has been greatly improved, but the detection cannot be realized for structures with overlapping projection profiles. Therefore, it is necessary for us to focus on the existing technology. In view of the deficiencies, a crack detection device for parts is proposed that can be combined with aux...

[0003] The existing cracking defects of stamping parts rely on naked eye detection or high-definition camera scanning test. The efficiency of high-definition camera scanning test has been greatly improved, but the detection cannot be realized for structures with overlapping projection profiles. Therefore, it is necessary for us to focus on the existing technology. In view of the deficiencies, a kind of crack inspection device for parts can be combined into a closed whole by means of auxiliary tooling and parts, filled with dry air after sealing, and used to detect the leakage rate per unit time by using a high-sensitivity leakage detection unit to determine whether there is a crack defect
