lathe control circuit

Abstract

The invention discloses a lathe control circuit which comprises a control circuit board. A potential transformer is connected to the control circuit board, the potential transformer is electrically connected with a null line and a live line, a rheostat is electrically connected to the control circuit board, a first relay is electrically connected to the rheostat, a normal close switch is electrically connected to the first relay, a start button is electrically connected to the control circuit board, the normal close switch and a normal open switch are connected to the start button in series, the normal close switch is electrically connected with the normal open switch, a second relay and a third relay are sequentially connected between the normal open switch and the rheostat in parallel, and two first relay contacts, a first switch, a second switch and an indicator light are sequentially connected between the normal open switch and the control circuit board in parallel. By means of the mode, the lathe control circuit can guarantee operation safety of a machine tool and is safe and stable.

Description

technical field [0001] The invention relates to the field of circuits, in particular to a lathe control circuit. Background technique [0002] During the lathe operation, since the new trainees are operating the lathe for the first time, they feel nervous. In addition, ordinary lathes do not have automatic parking protection devices. Once they do not operate according to the safety technical operation regulations, personal and equipment safety accidents may occur. The accidents that lathes are prone to occur among new students mainly include the following: Chuck wrench hurts people. After novice workers use the chuck wrench to clamp the workpiece on the chuck, such accidents often occur: that is, they forget to take the chuck wrench off the chuck and start the lathe, and the chuck wrench opens with the rotation of the chuck. The hand of the new student was hurt by falling down. Once such an accident happened, the skin and flesh would be damaged at the slightest, and the fin...

AI Technical Summary

Problems solved by technology

During the processing, when the sliding crate moves to the left, Xin Xuegong sometimes only pays attention to the processing situation and ignores the position of the tool holder, which is quite prone to accidents where the tool holder and the chuck collide

The reasons for the above-mentioned safety accidents are mainly because: (1) I am too nervous, and I lose sight of the other.

It is the first time for new students to come into contact with lathes, and the speed of lathes is relatively high. Some new students will be quite nervous, worried that they will not do well, and worry that they will have safety accidents.

(2) Unskilled in operation, the master does not listen carefully during the demonstration, does not master the essentials of lathe operation, will be in a hurry during processing, and is prone to safety accidents

(3) Failure to operate according to the operating procedures. Before each workpiece is processed, the master explains the corresponding operating procedures and demonstrates them on the lathe. However, some new students always like to go their own way and ignore the operating procedures, resulting in safety accidents

(4) The mind is not concentrated, the energy is scattered, and standing next to the lathe for a long time to process the workpiece, the mind will not be concentrated, the energy is scattered, and safety accidents are prone to occur
