Abstract

The invention discloses a lathe electric tailstock intelligent control device based on a singlechip, which includes a keyboard, a display, a singlechip, a storer, a power supply, optoelectronic isolators, a quadruple frequency circuit and a digital to analog circuit, wherein the keyboard is connected with the singlechip through a keyboard interface circuit; the display is connected with the singlechip through the display interface circuit; the storer is connected with the singlechip; rotational speed impulse is connected with the quadruple frequency circuit through a first optoelectronic isolator; the quadruple frequency circuit is connected with the singlechip; the singlechip is connected with the digital to analog converter through a second optoelectronic isolator; and the digital to analog converter is driven by a servomotor. The device is provided with the human-computer interface consisting of the LCD and the membrane keyboard and used for setting operational parameters, so as to control the electric tailstock driven by the servomotor to perform the pre-arranged actions, is convenient to operate, has complete functions and simple structure, and is low in cost and high in reliability.

Description

Technical field: [0001] The invention relates to a control device for an electric tailstock of a lathe, in particular to a single-chip microcomputer-based electric tailstock of a lathe capable of controlling the servo motor in the electric tailstock of the lathe to complete constant torque tightening, speed limiting, positioning and remote control Intelligent control device. Background technique: [0002] The control methods of the holding force of the lathe tailstock are: hydraulic tailstock, which is manually adjusted by the pressure regulating valve; electric tailstock, the tailstock center is driven by a servo motor, and the torque control mode of the servo drive system is used to pass a given voltage. Take control. At present, all lathes use a numerical control system to control an electric tailstock driven by a servo motor. The system cost is high and cannot work independently from the numerical control system. Summary of the invention: [0003] In order to make up for the...
