Abstract

The invention discloses a parameter adjustable cam profile drawing instrument based on a relative motion principle. The parameter adjustable cam profile drawing instrument comprises a cam profile drawing unit, a belt transmission device and an automatic display device that are arranged on a bottom plate, wherein the cam profile drawing unit comprises a lifting table device; a telescopic arm device is arranged on the lifting table device; a drawing pen is arranged on the telescopic arm device; a drawing panel is arranged below the drawing pen, and is connected with a drawing panel driving device; the belt transmission device and the automatic display device are arranged on the side surface of the drawing panel; the automatic display device comprises a display arm; the display arm is connected with a display arm driving device; a small suction disc is arranged below the display arm, and is connected with an air pump; and the lifting table device, the telescopic arm device, the drawing panel driving device, the belt transmission device and the automatic display device are connected with a control panel. The parameter adjustable cam profile drawing instrument realizes the effect of automatically displaying cam profile drawing, and solves the problem that the conventional cam profile curve design method is low in design accuracy.

Description

technical field [0001] The invention relates to the field of cam contour drawing technology and teaching instruments, in particular to a parameter-adjustable cam contour drawing instrument based on the principle of relative motion. Background technique [0002] The design of cam profile curve in the course of mechanical principle is the design principle of inversion method. This principle is applied to the analytical method and the drawing method. This is also the basic principle commonly used by designers before cam profile machining. This principle is also relatively easy for students to accept, and can be programmed and controlled by a computer. Compared with the drawing method, the analysis method is more complicated and cumbersome. Therefore, the cam profile curve designer generally adopts the manual drawing method. Although the computer is also used for corresponding control, the radial dimensions of the cam are determined by drawing, and the accuracy is very low. , i...
