Title:
A HAND AND PRESS-BUTTON DUAL-WAY MANUAL PULSE GENERATOR WITH BUILT-IN INDICATOR LAMPS
Document Type and Number:
WIPO Patent Application WO/2008/086679
Kind Code:
A1
Abstract:
This invention discloses a hand and press-button dual-way manual pulse generator with built-in indicator lamps, which includes: the rotation pulse input unit and a CPU. The CPU connects with forward and inverse rotation indicator lamps. The rotation signal input unit and/or the press-button signal input unit transmit the output signal to the CPU. The rotation pulse input unit transmits the output signal to the CPU where the output signal is processed and the control signal is then outputted through the difference chip. Meanwhile, the CPU collects control signal through the feedback circuit to realize self-check after the machine is turned on. This pulse generator has a non-contact structure extending significantly its service life than prior art, which makes it durable. In addition, by installing controller, indicator lamps, and press-button control on the manual pulse generator, it offsets the technical weaknesses of the current manual pulse generator, reduces the fault occurring rate, and greatly enhances work efficiency. Besides, it has a simple structure that it is easy to manufacture and to widely spread in the field of the machine tool control.
