Problems solved by technology
[0002] Aiming at the time-consuming, unclear concepts and low efficiency of students studying "Principles of Mechanics", we have deeply analyzed the difficulties related to the principles of mechanics, and designed a The teaching aids about cams can be used by teachers as teaching aids to explain the knowledge of the mechanical principles of the cam part, and can also be used as experimental equipment, aiming to make it easier for students to learn the course of "mechanical principles" and deepen their understanding The understanding and mastery of the corresponding knowledge points makes the learning process real, vivid and interesting, saving students' precious time and improving learning efficiency

Embodiment Construction
[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] A device for drawing a cam motion diagram in the present invention includes a frame, a main transmission part, a fixed disc 1, a translation plate 22, a synchronous belt tensioning mechanism, a follower mechanism and a cam.
[0021] Such as figure 1 , figure 2 As shown, the frame is composed of a base plate 12, a rear plate 13 and a front plate 34. The length of the front plate is less than the length of the rear plate. The front board and the rear board are parallel to each other and are vertically fixed on the base board. An optical axis guide rail fixing frame 4 is arranged at a position where the rear plate is higher than the front plate, and two mutually parallel optical axis guide rails 3 are horizontally arranged on the optical axis guide rail fixing frame 4 .
[0022] Such as Figure 4 As shown, the main transmission components inc...

The invention discloses an apparatus for drawing a cam motion chart. The apparatus comprises a frame, a main transmission part, a fixation disc, a translation plate, a hold-in range tensioning mechanism, an eccentric mechanism, a follower mechanism and a cam. Compared to a conventional teaching aid, the apparatus provided by the invention has the advantages: almost all explanation of knowledge points of motion rules related with a cam motion curve map is covered, the motion curve maps of cams in any shapes can be drawn, and such parameters as a cam turn angle, a basic circle dimension, a return travel angle, a travel angle, a farthest dwell angle, a nearest dwell angle and the like can be effectively detected. The apparatus is practical and convenient, greatly deepens students' understanding of a cam motion curve, facilitates teaching and improves the teaching quality.
