Problems solved by technology

Since the electrical life of the mechanical contacts of the relay is short, and the mechanical action frequency of the automatic lathe is high, the relay will reach its service life in a short time, and the failure rate of the electrical control system is high.
And the use of programmable logic controller (transistor as control output) is more expensive

Embodiment Construction

[0021] See attached figure 1 , the present invention is made up of interface circuit board 1, signal processing circuit board 2, display circuit board 3 three parts.

[0022] Referring to the accompanying drawing 2, the interface circuit board 1 is composed of three parts: an input photoelectric isolation circuit, an output photoelectric isolation circuit, and a regulated power supply circuit. The travel switch signal, button switch signal, and proximity switch signal are input to the input photoelectric isolation circuit of the interface circuit board, and there are 12 switch input circuits in total. In addition, resistors 28, 26, and transistor 2 form an output current sampling amplifier circuit, and the output current signal is also input to the input photoelectric isolation circuit of the interface circuit board. When the current value of the output circuit exceeds the set value, the single-chip microcomputer will immediately interrupt all The control output and give the ...

Description

Technical field: [0001] The invention relates to a controller of an automatic lathe for bearing rings controlled by a single-chip computer, which is suitable for the occasions of sequence control, fault self-diagnosis and working cycle counting of the automatic lathe for bearing rings. Background technique: [0002] At present, automatic lathes for bearing rings are widely used in the small and miniature bearing manufacturing industry, and their electrical control circuits usually use relay control circuits or programmable logic controller (PLC) circuits. These control circuits are not equipped with fault self-diagnosis and cycle Times counting function. Since the electrical life of the mechanical contacts of the relay is short, and the mechanical action frequency of the automatic lathe is high, the relay will reach its service life in a short time, and the failure rate of the electrical control system is high. And the use of programmable logic controller (transistor as con...
