Claims

[Scope of utility model registration request]

a camshaft having a cam 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 a change in the contour shape of the measuring head into a positional displacement; a measuring section that converts the positional displacement of the measuring head into a measured value and outputs the measured value; and a measuring section that holds the measuring section and guides the parallel movement with respect to the rotation axis. a guide rail, 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, and a measurement head drive unit that optically detects the position of the cam and an optical sensor detecting section for positioning the measuring section; an input section for inputting and storing measurement rotation angle pitch data set to divide one revolution of the cam into equal angles; a calculation storage unit that calculates and stores the acceleration of the cam from the rotation angle and the position displacement output from the measurement unit when the measurement rotation angle pitch specified by the input unit is reached; and a rotation angle output of the rotation drive unit. ,
A display section that displays the positional displacement of the measurement section and an acceleration output of the calculation storage section, and a measurement start command that moves the measurement section on the guide rail and causes the optical sensor detection section to detect the cam on the camshaft. A control unit that controls the measuring unit to stop when detected, rotate the cam once, measure the positional displacement of the cam for each measurement rotation angle pitch specified by the input unit, calculate and store and display the acceleration. and a cam measuring machine.
