A transmission device capable of automatically centering the preheating position of a cutting gun and a method of using the same

Abstract

The invention relates to a transmission device capable of automatically centering the preheating position of a cutting torch, including a motor, a worm gear reducer, an output shaft one, an overrunning clutch, an output shaft two, a cutting torch clamping device, a cutting torch, a synchronous mechanism and a screw adjustment The device, the motor is connected with the worm gear reducer, wherein the output shaft one is installed on the worm gear reducer, the output shaft one is equipped with a counterweight, the output shaft two is installed on the bearing seat assembly, and the output shaft one and the output shaft two are connected by an overrunning clutch Up, the cutting gun clamping device and the cutting gun are installed on the output shaft 2, and the cutting gun is provided with a screw adjustment device to push the cutting gun in the vertical direction, and the screw adjustment device is installed on the clamp arm; it realizes the complete circular motion of the worm wheel , Effectively extend the service life of the worm gear reducer.

Description

technical field [0001] The invention belongs to the technical field of continuous casting flame cutting machines, and relates to a transmission device capable of automatically centering the preheating position of a cutting torch and a use method thereof. Background technique [0002] The cutting gun of the billet flame cutting machine of the continuous casting machine is generally driven by a motor. After the billet is cut, the cutting gun returns to a fixed position (the edge of the billet) and waits for the next cutting. This position is called the original position of the gun, that is, In the traditional design, the original position of the cutting torch, the edge of the slab and the preheating position coincide. A proximity switch is installed on the original position of the gun. When the cutting gun returns to the original position of the gun and touches the proximity switch, the proximity switch will generate an electrical signal to the electrical control system, and t...

AI Technical Summary

Problems solved by technology

When adjusting the original position of the gun, the operator is in the harsh environment of high temperature radiation and cutting steel spatter. The adjustment is difficult, and the safety of the operator cannot be guaranteed. The number of times to adjust the original position of the gun in each work shift reaches 7 -8 times with a lot of work

At the same time, the entire forward and reverse travel is driven by the motor. Since the swing of the cutting torch is only at a limited angle, the meshing between the worm gear and the worm of the worm gear reducer is only on a limited number of teeth. After repeated use, the worm gear and the worm If the gap is too large, the cutting torch is discontinuous on the swing stroke, resulting in uneven and jagged lines of the casting slab
