The role of cam buckle
1. The law of movement of the valve stem defines the outline of the cam. When the sagittal cam profile is in contact with the flat bottom of the valve stem, the valve stem reciprocates; when the arc segment with the center of the cam turning center comes into contact with the valve stem, the valve stem will stay still . Therefore, with the continuous rotation of the cam, the valve stem can obtain intermittent, regular motion.
2. When the cylinder cam rotates, the flanks of the groove force the rocking follower to oscillate, thereby driving the associated carriage. As for the movement of the tool holder, it depends entirely on the shape of the groove.
