Abstract

The invention discloses an algorithm for a deformation quantic-polynomial type cam operation curve, aiming to limit operation parameters during swinging of a swing arm of a cam. The cam constructed by the algorithm does quantic-polynomial motion in the initial phase of the curve during swinging, then does constant-speed motion in the current speed when reaching the highest speed, and decelerates according to the quintic polynomial until stopping motion when moving to a preset point at the constant speed. By the algorithm, the maximum speed of the swing arm of the cam can be reduced, and centrifugal force of a cam mechanism can be reduced.

Description

Technical field [0001] The invention relates to a cam operating curve algorithm. Background technique [0002] At present, the commonly used cam curve algorithm is relatively mature, but in practical applications, for some mechanisms with longer swing arms, due to the larger swing arm radius, higher speed means the corresponding centrifugal force increases. For some rotary turntable mechanisms Will have an impact. [0003] The commonly used cam curve equations are as follows: [0004] 1. Isokinetic movement [0005] At the beginning and end of the stroke, there is a sudden change in speed, and the instantaneous acceleration is infinite, which makes the mechanism have a strong impact, which is suitable for occasions with low speed and light load. [0006] 2. Wait for acceleration and other deceleration movement [0007] The speed curve is continuous and there is no rigid impact, but there is a sudden change in the acceleration curve at the beginning of the stroke and the acceleration / de...
