APPARATUS FOR AUTO CONTROL BORING DEPTH OF BORING MACHINE

摘要

PURPOSE: A device for automatically controlling the boring depth of a boring machine is provided to automatically return a boring machine to an initial position after a boring work. CONSTITUTION: A device for automatically controlling the boring depth of a boring machine comprises a wire module(10), a sensor module(20), a count module(30), a relay module(40), and a hydraulic solenoid module(50). The wire module has a wire and first and second rollers. The wire is connected to a table and is wound around the first and second rollers. The table supports a boring machine(1). The sensor module has a rotary plate and a sensor. The rotary plate is installed in the first roller and has slits. The sensor senses the slits and outputs an electrical pulse signal. The count module has a counter and an indicator. The counter counts the signal sensed from the sensor. The indicator indicates the counted signal. The relay module has multiple relays which switch power applied from the count module. The hydraulic solenoid module returns the boring machine to an initial position using a cylinder and a piston rod connected to a hydraulic solenoid.
