[0026] The return limit contact 2 includes a cylindrical second mounting body 21; a mounting groove is provided on the lower end surface of the second mounting body 21, and a second copper contact 22 is fixedly installed in the mounting groove; a mounting column 23 is protrudingly provided on the upper end surface of the second mounting body 21; a second connecting hole 24 is provided at the lower end of the outer diameter surface of the second mounting body 21, and the second connecting hole 24 passes through the second mounting body 21 and is connected with the mounting groove provided on the lower end surface of the second mounting body 21.
[0027] Working principle:
[0028] The limit signal contact module of the utility model is fixedly installed on the telescopic cylinder 3 of the processing equipment, and the unloading limit contact 1 is fixedly installed on the upper end of the telescopic cylinder 3 of the processing equipment through a threaded hole set at the lower end of the first mounting body 11; the return limit contact 2 is fixedly installed on the lower end of the telescopic cylinder 3 of the processing equipment through a mounting column 23; the unloading limit contact 1 and the return limit contact 2 are respectively connected to the electrical signal of the processing equipment controller through signal connecting lines; the signal connecting lines pass through the first connecting holes 14 and the second connecting holes 24 set on the unloading limit contact 1 and the return limit contact 2, respectively, and are connected to the first copper contact 12 and the second copper contact 22, and the other end is connected to the electrical signal of the processing equipment controller.
[0029] When in use, the processing equipment controller controls the telescopic rod of the telescopic cylinder 3 to extend, so that the unloading device 4 fixedly installed at the lower end of the telescopic rod of the telescopic cylinder 3 descends. After the telescopic rod of the telescopic cylinder 3 is extended to the right position, the unloading device 4 descends to the working position, and the first copper contact 12 on the unloading limit contact 1 contacts the upper part of the telescopic rod of the telescopic cylinder 3. The first copper contact 12 sends a signal to the processing equipment controller, and then the controller controls the unloading device 4 to work. After the unloading device 4 completes the work, the controller controls the telescopic rod of the telescopic cylinder 3 to retract, driving the lower end of the telescopic rod of the telescopic cylinder 3. The feeding device 4 rises and returns to the origin. When the feeding device 4 rises and returns to the origin, the second copper contact 22 on the return limit contact 2 contacts the contact protrusion set on the upper end surface of the feeding device 4; the second copper contact 22 sends a signal to the processing equipment controller, and then the controller controls the cutting feed device to feed and cut, so as to achieve the limiting effect of the feeding device 4 during the processing. The feeding device 4 works after reaching the processing position, and performs cutting after returning to the origin, so as to prevent conflicts and collisions between the processing components and ensure safety.
[0030] The processing equipment is linked and controlled by the unloading limit contact 1 and the return limit contact 2 respectively arranged at the upper and lower ends of the telescopic cylinder 3. Compared with traditional sensor induction, it is more practical and can be used in any environment. It is also durable and its service life is greatly improved.
[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
[0032] Although the present disclosure has been described in detail with reference to the exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of the present disclosure.
