Signal board for electric tool post with answer signal

Abstract

The invention discloses a signal sending disk with answer signals for an electric tool rest. The signal sending disk comprises a disk body, a circuit board and at least one station magnet steel, wherein the circuit board is arranged in the disk body and provided with at least one induction module and at least one answer signal magnet steel, each induction module comprises a station Hall element, an answer signal Hall element, a current-limiting resistor, a diode and a signal output terminal, and the station Hall elements, the answer signal Hall elements, the current-limiting resistors, the diodes and the signal output terminals are arranged on the circuit board. The station Hall elements are in one-to-one correspondence with the station magnet steels, the answer signal Hall elements are in one-to-one correspondence with the answer signal magnet steels, the station Hall elements are arranged at the edge of the circuit board, the answer signal Hall elements are arranged on the inner sides of the station Hall elements on the circuit board, and station signal output ends of the station Hall elements and answer signal output ends of the answer signal Hall elements are sequentially connected with the current-limiting resistors and the diodes and then connected with the signal output terminals. The signal sending disk is stable and reliable in signal output, and output signals contain the answer signals.

Description

technical field [0001] The invention relates to a sending plate for an electric knife rest with a reply signal, and belongs to the technical field of electric knife rests. Background technique [0002] At present, in CNC machine tools, the indexing of the electric tool post is controlled by a microcomputer. The electric tool post disclosed at present is equipped with a sending plate, which is fixed on the main shaft of the electric tool post, and the sending plate corresponds to each tool. A Hall element is fixed at the frame station, and a magnetic steel is fixed on the upper tool holder body. When the electric tool holder needs to be changed, under the control of the microcomputer, the motor rotates forward, driving the upper tool holder body to rotate, and when the magnetic steel turns to the microcomputer When controlling the station set in the program, the Hall element on the station on the sending board sends a signal to notify the microcomputer, and the microcomputer ...

[0002] At present, in CNC machine tools, the indexing of the electric tool post is controlled by a microcomputer. The electric tool post disclosed at present is equipped with a sending plate, which is fixed on the main shaft of the electric tool post, and the sending plate corresponds to each tool. A Hall element is fixed at the frame station, and a magnetic steel is fixed on the upper tool holder body. When the electric tool holder needs to be changed, under the control of the microcomputer, the motor rotates forward, driving the upper tool holder body to rotate, and when the magnetic steel turns to the microcomputer When controlling the station set in the program, the Hall element on the station on the sending board sends a signal to notify the microcomputer, and the microcomputer instructs the motor to reverse, the reverse time is controlled by the microcomputer, and the electric knife rest is positioned and locked. The circuit board is installed on the disk body, the Hall element is fixed upright on the edge of the circuit board, and the magnetic steel is installed on the magnetic steel bracket of the upper tool holder body. Some electric tool holders in the prior art need to have a reply signal, so as to It is convenient to control, but the sending panel with the above structure does not have answer signal output, and cannot meet the use of electric knife holders that need answer signals
