Abstract

The invention discloses an involute interpolation control forming method, belongs to the field of mechanical control, and aims to solve the problem that an involute trajectory can not be accurately controlled. A controller is used for outputting a control signal to an electric motor to control the rotation angle and the revolving speed of the electric motor, the controller consists of an unfoldingangle controller and a generation line controller, a control algorithm is built in the unfolding angle controller, the control signal of the rotation angle and the revolving speed is output to an unfolding angle control motor driver, a control algorithm is built in the generation line controller, and the control signal of the rotation angle and the revolving speed is output to the generation linecontrol motor driver. The method has an effect on improving the control accuracy of the involute trajectory.

Description

technical field [0001] The invention belongs to the field of mechanical control, and relates to an involute interpolation device and a control molding method. Background technique [0002] The machining of involute gears in mechanical manufacturing usually adopts generating method or forming method. The generating method generally uses an involute gear cutting machine tool, such as a hobbing machine or a gear shaping machine; the transmission chain of the involute gear cutting machine tool is long and the structure is complex, which reduces the machining accuracy of the machine tool; therefore, the manufacturing accuracy of the gear decreases. In addition, the structure of the involute gear cutting tool is very complex, and its tool manufacturing and tool grinding processes are complex and technically demanding. The forming method is to use a special gear milling cutter with an involute edge shape to cut and process the gear teeth to ensure the correctness of the involute t...
