Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1~3 As shown, a linear follower planar cam mechanism demonstrator includes a frame 14 composed of a front frame 141 and a rear frame 142. The frame 14 is provided with a rotating shaft 1 that can rotate relative to the frame 14. , the middle part of the front frame 141 and the rear frame 142 is provided with a circular through slot, and the shaft 1 is located on the rear side of the rear frame 142. A central gear 4 and a handle 5 are arranged on the shaft, which is located in the rear frame. 142 is provided with a circular turning plate 6 that can rotate relative to the rotating shaft 1 on the shaft on the front side. The circular turning plate 6 is embedded in the circular through groove of the front frame 141. On the rotating shaft 1 and detachable plane cam 3, the front side of the plane cam 3 is provided with a circu...

Abstract

The invention relates to a planar cam mechanism demonstration instrument for a translating follower and a using method thereof. The demonstration instrument can adopt a planar cam to simultaneously demonstrate follower displacement analysis and cam theoretical profile synthesis of a tip end, a roller and a planar cam mechanism of a flat-bottomed translating follower, can demonstrate the motion law of different followers and the cam theoretical profile synthesis of basic parameters of different cam mechanisms, and can demonstrate follower displacement analysis and cam theoretical profile synthesis of the planar cam mechanism of the translating follower under the condition that only a planar cam is used, so that a translating cam is avoided to use, cam profiles with different base radiuses can be synthesized by using the same displacement diagram, and the knowledge that different cams can be used to draw the same displacement curve is explained.

Description

technical field [0001] The invention relates to the field of teaching instruments, and relates to a demonstration instrument of a planar cam mechanism of a direct-moving follower and a use method thereof. Background technique [0002] At present, in the field of mechanical teaching, the displacement analysis of the follower of the planar cam mechanism and the synthesis of the cam profile are very important contents, and the synthesis of the cam profile is also a difficult point in teaching and learning. The displacement analysis of the follower is to obtain the displacement curve of the follower according to the existing planar cam mechanism, and the synthesis of the cam profile is to obtain the cam profile from the known displacement curve of the follower and the basic parameters of the cam mechanism. Therefore, the use of teaching aids can make it easier for students to understand the principles and deepen their understanding and comprehension; Shaped cams and moving cams...
