Embodiment 1）

[0022] See Figure 1-2 , the cam profile detection numerical control system of the present embodiment includes: a numerical control turntable 1 for driving the cam 10 to rotate horizontally and coaxially around the vertical mandrel 1-1, and a guide rail synchronous belt assembly 3 horizontally arranged on one side of the numerical control turntable 1 , be located on the synchronous belt 3-1 of this guide rail synchronous belt assembly 3 and the laser ranging head 2 on one side of the cam 10, the grating ruler displacement sensor 4 for measuring the horizontal displacement of the laser ranging head 2, An encoder 5 and an industrial computer for detecting the rotation angle of the cam 10; the industrial computer controls the action of the numerical control turntable 1 and the guide rail synchronous belt assembly 3, and according to the laser distance measuring head 2, the grating ruler displacement sensor 4 And the data that encoder 5 measures obtains the outer profile data of c...

Embodiment 2）

[0043] On the basis of Embodiment 1, this embodiment has the following modifications:

[0044] In order to eliminate the processing or installation error of the mandrel 1-1, which affects the accuracy of cam profile detection, the detection method of the cam profile detection device includes:

[0045] A. Detect the outer edge data of the mandrel 1-1: when the mandrel 1-1 starts to rotate a circle, the distance between the laser measuring head 2 and the outer circle of the mandrel 1-1 is the first distance Always control within the measuring range of the laser measuring head 2, and simultaneously detect and record the rotation angle θ i corresponding to the first spacing , and the mover 3-1 is horizontally aligned with the hard zero position The spacing of the second spacing ;

[0046] B. Fit the cam 10 on the spindle 1-1 without clearance, if the outer contour data of the cam 10 is known , then at the same time when the cam 10 is controlled to rotate one revolution, ...
