Curved surface shell outer surface detection device

Abstract

The invention discloses a curved surface shell outer surface detection device. The device comprises a bottom plate, four guide posts fixed on the bottom plate, a top plate, a sliding plate, a detection cylinder, a top rod, a lifting switch, a plurality of height detection mechanisms, an analog-to-digital converter and an industrial control PC, wherein the industrial control PC comprises a host and a display, the analog-to-digital converter is connected with the host through a data interface, each height detection mechanism is connected with a group of signal lines, and the other end of each group of signal data transmission lines is connected with the analog-to-digital converter. The curved surface shell outer surface detection device has the advantages that: (1) the structure is simple, and the operation is convenient, (2) the detection speed is high, and the detection requirement of large-scale industrial production can be met, and (3) the adjusting function is good, and it is convenient to finely adjust the position of the height detection mechanisms in the detection process.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for the outer surface of a curved shell. Background technique [0002] At present, for mass-produced curved surface shell parts, especially curved surface shell parts stamped or injection molded, usually only some products are randomly inspected in the trial production stage, and only some important parameters on the curved surface When testing, either use a three-coordinate measuring instrument for testing, or use ordinary calipers or micrometers and some special fixtures for testing, and the above two testing methods can only be tested point by point. Therefore, the detection speed is very slow, and it is impossible to quickly complete the detection of a large number of curved surface shells. In addition, the price of the three-coordinate measuring instrument is very high. In order to make a special fixture, it also requires a large cost. The device also has the defect ...
