Anti-overloading system capable of being encrypted for electric drill

Abstract

The invention relates to an anti-overloading system capable of being encrypted for an electric drill. The anti-overloading system capable of being encrypted for the electric drill is mainly composed of a turn plate, a spindle, a drill head, a spring, a contact body, a large button, a small button, a contact system, an electric system, a gear system, a circuit, a fixing orbit, a contact spring, an alarm, a sensor, an AVR single chip, a ZigBee module and a dial switch. The anti-overloading system capable of being encrypted for the electric drill is capable of automatically cutting off the electric drill under an overloading state, and therefore, a motor is avoided from burning out, and the life span of the machine is prolonged. The turn plate is connected with the spindle, the contact body is connected with the spring, the spring is fixed in the fixing orbit, the fixing orbit is firmly connected with the turn plate, and the turn plate contacts with the contact spring. When working normally, two contact bodies are divided by a centrifugal effect, when the overloading is generated, the rotating speed of the spindle is quickly reduced, and at the moment, the centrifugal effect is not enough to combine the two contact bodies, the circuit is turned on, current signals are generated and sent to the contact system, the signals are sent to the electric system after being processed by the contact system, and then the motor power is cut off. The anti-overloading system capable of being encrypted for the electric drill is easy to operate, convenient to use, easy to popularize and capable of realizing automatic detection and control.

Description

technical field [0001] The invention relates to an overload prevention system, in particular to an overload prevention system for an encrypted electric drill. Background technique [0002] An electric drill is a drilling tool that uses electricity as power. It is a conventional product in electric tools, and it is also the most demanded electric tool product. The annual production and sales volume accounts for 35% of China's electric tools. The main specifications of the electric drill are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm, etc. The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and works. The working device is driven by the transmission mechanism, and the gear is driven to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. [0003] Electric drills in the pri...
