How to measure the car engine camshaft?

The camshaft is a key component that affects the working quality of the valve mechanism of the automobile engine. Its function is to ensure that the engine valve group has an accurate and stable good motion law. The measurement of the camshaft is of great significance. The following camshaft wholesale, camshaft manufacturers and camshaft brand companies will talk about the specific operation methods as follows:

The following camshaft wholesale, camshaft manufacturers and camshaft brand companies will talk about the specific operation methods as follows:

Due to the different forms and shapes of the follower of the cam mechanism, the motion laws of the valve with the same shape of the cam shape are different.

1. For the lower camshaft valve mechanism, the measured value of the lift conforms to the motion law of the mobile follower (tappet);

2. For the overhead camshaft valve mechanism, it conforms to the valve lift law of the cylindrical surface of the swinging follower, and also needs to be converted into the lift measurement value of the mobile follower, that is, the rocker arm and the cam. The valve lift of the swinging cylinder in contact with the cam profile is converted into the cam lift of the centrically movable plane probe. Because the plane probe is used, it is beneficial to the processing of the cam profile and the measurement of the cam lift, but this involves the conversion of the probe during the measurement.

3. That is to say, when the probe that meets the design requirements cannot be used due to the limitation of processing and measurement process conditions or a special occasion, it is allowed to use the probe conversion method to use the probe that does not meet the design requirements Cam measurement.
