Title: Camber inspection device
Inventor: MASUDA KENJI
IPC: G01B21/30
Filed: 1989-04-18
Abstract: PURPOSE:To inspect the accuracy of a work on an on-line basis by calculating and evaluating the camber of a body to be inspected from the relation between a distance detected by a distance detector and a known distance. CONSTITUTION:A value 2l (distance between two feed holes in the absence of chamber) and a value X (permissible maximum deflection quantity) are inputted from a console 13. Then the measured value of the distance detecting device 4 is inputted according to the timing of a timing signal generator 5 to find the distance delta. (2l - measured value = 2delta). Then a value sintheta/theta is found from an equation III. (theta is an angle). Then data in a storage device 14 are retrieved to obtain the corresponding angle theta. Then a camber quantity (x) is found from inequalities II and I and displayed on a display device. The distance (x) is compared with the deflection quantity X and when x<=X, a return to the equation II is made. When x > X, on the other hand, it is decided that abnormality occurs, the abnormality occurrence is indicated on the display device, and the line is stopped.
