INFORMATION DISPLAY APPARATUS FOR MACHINE TOOLS

摘要

The present invention relates to an information display device for a machine tool. The information display device is configured by fixing and coupling a frame body (A) and a circuit board (1). The frame body (A) has a storage chamber (2) having a specific spaced unit on the inside and a heating pad (3) formed on a side of the floor surface of the storage chamber (2) in a protruding manner as well as a through-hole (5) of a cable used for power supply and signal input operations. The circuit board (1) is inserted into the storage chamber (2) to be installed and includes a character display unit (m) for expressing characters defined and a number display unit (n) for expressing numbers on the front surface as well as a CPU on the back surface. A reinforced glass viewing window (11) is fixed and coupled to the front peripheral edge of the storage chamber (2) by forming a silicon-filled groove (7) and filling the silicon-filled groove (7) with silicon. Accordingly, the information display device can easily recognize and display the information defined in an external signal such as display information or command information being input to a machine tool or a processing apparatus in a visual manner. The information display device has high durability in an environment having the occurrence of vibration or impact as well as excellent sealing performance to be easily used in a low-temperature and high-temperature environments. The information display device can be used for a long time without failure in a hazardous industry environment having leaks, moisture, oil, and grease.
