Embodiment Construction

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

[0055] First, determine the outline of the cam to be demonstrated, the follower 810 stroke h813, the base circle radius r807, the eccentricity e806, and the thrust angle φ 1 801, far angle of repose φ 2 802, return angle φ 3 803. Near angle of repose φ 4 805; the base circle radius r807 of the cam is adjusted by the base circle screw nut mechanism 607, the eccentric distance e806 is adjusted by the eccentric distance screw nut mechanism 604, and the stroke h813 is adjusted by the stroke adjustment dial 112, the stroke switch support 303, and the stroke adjustment slider 408 , through the prompt of the display screen 702, the push angle φ is input in turn by the numeric keyboard 703 1 801, far angle of repose φ 2 802, return angle φ 3 803. Near angle of repose φ 4 805. Press the "*" key to confirm the input, and press the "#" k...

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, in particular to a cam contour line generator and a generation method. Background technique [0002] The cam mechanism plays an important role in the mechanical design. The cam only needs to design the appropriate cam profile to make the follower get any desired movement, and the structure is simple, compact and convenient to design. Therefore, it is widely used in automatic machine tools, 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 motion, swing, constant velocity motion and unequal motion. [0003] The cam mechanism is generally a high auxiliary mechanism composed of three components: a cam, a follower and a frame; the cam usually rotates co...
