Abstract

A controller for a rivetting machine having a hydrauilc cylinder connected with a hydraulic power source and having a piston shaft, a motor-driven spindle extending through and journaled to the piston shaft, and a rivet head forming tool secured to the bottom end of the spindle and carrying a forming shaft. The controller has a linear encoder for detecting the axial position of the piston shaft, an electric hydraulic servo valve provided in a hydraulic circuit between the hydraulic power source and the hydraulic cylinder, a machining data setting unit for setting machining data of the work unit and a control unit. The control unit performs predetermined operations by inputting the output of the linear encoder and the machining data and controls the hydraulic cylinder by controlling the electric/hydraulic servo vale based on the results of the operations to machine the work rivet according to the machining data.
