Problems solved by technology
[0002] In the traditional design, the signal of the automatic accessory head release is to use the signal ring and two proximity switches to detect the signal, and the electric plug is used to transmit the position signal of the accessory head, but the signal ring electric plug is rigidly connected, and the attachment head is long. Minor positional deviations when used for a long time and when the ram is connected may cause damage to the electrical plug and affect the reliability of the accessory head, and the two proximity switches rotate 360° relative to the signaling ring, the signaling ring and the protection The gap between the sheet metals causes the attachment head to be used for a long time, and iron filings and cutting fluid are easy to accumulate on the signaling ring, which causes the proximity switch to send an error signal or alarm, which affects the stability of the attachment head.

Embodiment 1
[0016] Such as figure 1 As shown, the loosening action of the accessory head is reflected in the downward action of the annular cover 10 connected with the pressure plate 11, and this action is transmitted to the guide post 14 through the central sending block 8 fixed with a cylindrical pin 9, and becomes reversed. Upward movement; this action is transmitted to the sensing block 4 by the signal rod 13 installed on the oil receiving pan 2 of the ram, and the upward movement of the sensing block 4 is sensed by the proximity switch, and the system can recognize that the attachment head is in a loose state.
Embodiment 2
[0018] Such as figure 2 As shown, the loosening action of the accessory head is reflected in the upward movement of the annular cover 10 connected with the pressure plate 11, and this action is transmitted to the guide post 14 through the sending block 8 fixed by the cylindrical pin 9 in the center, and becomes the reverse direction. Downward movement; this action is transmitted to the sensing block 4 by the signal rod 13 installed on the oil receiving tray 2 of the ram, and the downward movement of the sensing block 4 is sensed by the proximity switch, and the system can recognize that the attachment head is in a clamped state .

The invention relates to a loosening and clamping detection device of a machine tool automatic attachment head. The loosening and clamping detection device of the machine tool automatic attachment head comprises a switch installation rack (1), a ram oil receiver (2) and a transmission block (8). The switch installation rack (1) is embedded in the middle of the ram oil receiver (2). An approach switch (3) which is used for detecting a loosening signal is arranged at the upper end of the switch installation rack (1). An induction block (4) is arranged in the middle of the switch installation rack (1). A signal rod (13) is connected with the lower end of the induction block (4). The switch installation rack (1) which is arranged at the lower side of the induction block (4) is provided with an approach switch (6) which is used for detecting a clamping signal. A guide pillar (14) is arranged in the middle of a connecting body (15). The transmission block (8) is arranged at the right side of the connecting body (15). An annular cover (10) is fixedly connected with a pressing plate (11). Due to a lever principle of the transmission block and small spring force of a reset spring, the loosening and clamping detection device of the machine tool automatic attachment head has the advantages of being flexible in connection, capable of reducing impact, reliable, durable and low in installation accuracy.
