Claims

[Scope of utility model registration request]

a camshaft having a plurality of cams fixed on a rotating shaft; a rotary drive unit that continuously rotates the camshaft with respect to the rotating shaft and outputs the rotation angle; A measuring head that converts changes in the contour shape of each of the cams with respect to angle into positional displacement, a measuring section that converts the positional displacement of the measuring head into a measured value and outputs it, and a measuring section that holds the measuring section and connects it to the rotating shaft. a guide rail that guides parallel movement; a measurement unit drive unit that moves the measurement unit on the guide rail;
A measurement head drive unit that moves the measurement head in a direction perpendicular to the camshaft, a plurality of tags that position the measurement unit at the positions of each of the cams, and a plurality of tags that hold each of the tags and are connected to the rotation shaft. a tag guide for guiding the parallel movement of the cam; a tag detector for detecting the position of each of the tags; and an input section for inputting and storing measured rotation angle pitch data set to divide one revolution of each cam into equal angles. , Calculate the acceleration and phase angle difference of each cam from the rotation angle when the rotation angle from the rotation drive unit reaches the measurement rotation angle pitch specified by the input unit and the position displacement output from the measurement unit. a calculation storage unit that stores the rotational angle output of the rotary drive unit, a positional displacement of the measurement unit, and an acceleration and phase angle difference output of the calculation storage unit; Each time the tag detector detects each tag, the measuring section on the top is moved, and the measuring section is stopped, and the camshaft is rotated once, so that each of the cams is rotated at each measurement rotation angle pitch specified by the input section. A cam measuring device comprising: a control unit that measures positional displacement, calculates and stores acceleration and phase angle difference, and controls the display.
