Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-8, the present invention provides a technical solution:

a electromechanical chuck wrench mainly comprises a wrench 1, a signal transmitting device 2, a signal triggering device 3 and a signal receiving device 4; the signal emitting device 2 is positioned at the topmost part of the wrench 1, the signal triggering device 3 is connected to one side of the bottom of the wrench 1, and the signal receiving device 4 is connected with a motor control switch of a machine tool;

a rotating handle 5 is horizontally arranged at the top of the wrench 1, a limiting head 6 is vertically arranged at the bottom of the wrench 1, and a connecting port 7 is arranged at one side of the limiting head 6;

the middle of the signal trigger device 3 is provided with a metal sheet 9, a spring 10 is nested in the metal sheet 9, and two ends of the spring 10 are respectively nested on a spring post 11.

The signal transmitting device 2 is fixedly connected with the wrench 1 through threads; wherein, the top of spanner 1 is provided with the external screw thread, and the bottom of signal emission device 2 is provided with the internal thread. Signal emission device 2 mainly used detects spanner 1 and whether omits in the chuck recess to send out the signal, signal emission device 2 is convenient for with its dismouting through threaded connection.

The cross section of the limiting head 6 is square, and the wrench 1 is in clearance fit with the chuck groove through the limiting head 6. The limiting head 6 with the square cross section can be in limiting fit with the chuck groove, and tightness can be achieved through the wrench 1.

Two wires 8 are arranged inside the wrench 1; wherein, two wires 8 respectively extend from the signal transmitting device 2 to the connecting port 7. The two wires 8 are mainly used for connecting the signal transmitting device 2 and the signal triggering device 3.

The signal trigger device 3 is fixedly connected with a connecting port 7 at one side of the limiting head 6 through threads; wherein, the outer side surface of the signal trigger device 3 is provided with an external thread, and the inner side surface of the connecting port 7 is provided with an internal thread. Because the thread signal trigger device 3 is fixedly connected, the position of the thread signal trigger device is convenient to adjust, and the thread signal trigger device is convenient to detach and replace, so that the thread signal trigger device has good flexibility.

After the signal trigger device 3 is matched with the groove of the chuck along with the limiting head 6 of the wrench 1, the upper end and the lower end of a metal sheet 9 in the signal trigger device 3 can be respectively contacted with two leads 8, and a closed loop is formed.
