Abstract

The invention provides a rivet punching machine with a complete servo driving system and a working method thereof. The rivet punching machine is characterized by comprising a servo motor, a screw rodmechanism, a cylinder body, a pressed platform, a pressure sensor and a controller. The screw rod mechanism converts the rotation of an output shaft of the servo motor into the linear motion of a punch in the cylinder body; the pressed platform is located on the linear motion path of the punch; the pressure sensor is mounted at the bottom of the pressed platform; and the servo motor and the pressure sensor are electrically connected with the controller, and the pressure sensor serves as a trigger switch of the working state of the servo motor. When a rivet is punched, riveting is controlled bythe closed-loop servo driving system, riveting efficiency is guaranteed, the length of the punched rivet is accurately controlled, and therefore stable riveting and riveting quality are guaranteed, and a curve that pressure changes along with the length of the rivet can be generated.

Description

technical field [0001] The invention belongs to the technical field of riveting machines, in particular to a stamping riveting machine with a complete servo drive system and its working method. Background technique [0002] A riveting machine refers to mechanical equipment that uses rivets (solid rivets, hollow rivets, hollow rivets) to rivet objects together. The assembly is mainly completed by rotation and pressure, and it is mainly used in occasions that require riveting. Common riveting machines use pneumatic and hydraulic riveting, and electromagnetic riveting technology is used in specific occasions. [0003] For pneumatic riveting and hydraulic riveting, the common riveting methods include radial riveting method and rotary riveting method. The rotary riveting method is that the riveting head first makes point contact with the workpiece, and then pressurizes the surface of the workpiece through an air cylinder or hydraulic cylinder. The azimuth rolling makes the surf...
