The basic steps of designing cam profile curve are as follows:
Determine the base circle and its radius: the base circle radius r has been given as 50mm, and draw the base circle on the diagram.
Determine the motion law of the putter: According to the schematic diagram given in the title, the motion law of the putter is known. This is usually a displacement-time diagram or an angular displacement diagram.
Determine the relationship between cam angle and push rod displacement: from the motion law diagram of push rod, we can get the corresponding relationship between cam angle and push rod displacement.
Drawings:
Choose a starting point, usually choose the lowest or highest point of the cam as the starting point for drawing.
According to the motion law of the push rod, the cam profile is drawn step by step. For the rotation angle of each cam, the corresponding point on the cam profile is determined according to the displacement of the push rod.
Connect these points to form the contour curve of the cam.
Check and correction: after drawing, check whether the contour curve is smooth and conforms to the motion law of the push rod. Make corrections if necessary.
Since you can't draw directly here, I will provide a general process and idea. In practice, you need to use drawing tools (such as CAD software or manual drawing tools) to complete the drawing.
Finally, it should be noted that designing the cam profile curve is a relatively complicated process, which requires certain mechanical design knowledge and experience. If you are not familiar with this process, it is recommended to refer to relevant mechanical design textbooks or consult professional mechanical designers.
