Embodiment Construction

[0054] As shown in the accompanying drawings, the present invention will be further described below in conjunction with the accompanying drawings.

[0055] First, determine the contour line, follower stroke h, base circle radius r, eccentricity e, and thrust angle φ required by the cam to be demonstrated 1 , Far angle of repose φ 2 , return angle φ 3 , near angle of repose φ 4 The radius of the base circle of the cam is adjusted through the base circle screw nut mechanism, and the eccentric distance is adjusted by the screw nut mechanism of the eccentric distance. The stroke is adjusted by the stroke adjustment dial, the stroke switch support, and the stroke adjustment slider. Key in the thrust angle φ on the keyboard in sequence 1 , Far angle of repose φ 2 , return angle φ 3 , near angle of repose φ 4 , press the "*" key to confirm the input, press the "#" key to cancel the current operation, A, B, C, D on the keyboard correspond to constant acceleration and deceleratio...

Abstract

The invention belongs to the field of teaching instruments and particularly relates to a cam profile line generating instrument and a generating method. The cam profile line generating instrument comprises a rack, a constant acceleration and constant deceleration curve assembly, a cycloid curve assembly, a uniform speed curve assembly, a simple harmonic curve assembly, a curve selection assembly, a curve drawing platform and a control operation system, and the constant acceleration and constant deceleration curve assembly, the cycloid curve assembly, the uniform speed curve assembly, the simple harmonic curve assembly, the curve selection assembly, the curve drawing platform and the control operation system are installed on the rack. According to the cam profile line generating instrument and the generating method, cam teaching can be simpler, clearer, convenient and visual, learners can enjoy the joy of practice, cam profile lines with different parameters can be drawn by adjusting parameters of a cam, and the cam profile line generating instrument and the generating method have the advantages of being good in operability and high in demonstration performance.

Description

technical field [0001] The invention belongs to the field of teaching instruments, and in particular relates to a cam profile generating instrument and a generating method. Background technique [0002] The cam mechanism plays an important role in the mechanical design. The cam can make the follower move in any desired way only by designing the appropriate cam profile, and the structure is simple, compact and easy to design. Therefore, it is widely used in automatic machine tools and light industrial machinery. , textile machinery, printing machinery, food machinery, packaging machinery and mechatronics products are widely used; the main function of the cam mechanism is to make the follower complete various complex movements according to the work requirements, including linear movement, swing and constant speed movement and non-uniform motion. [0003] The cam mechanism is generally a high-level mechanism composed of three components: the cam, the follower and the frame; th...
