Synchronous lifting mechanism

Abstract

The invention relates to a synchronous lifting mechanism of a straight bar multi-cutting torque cutter, which comprises an active part, a left driven part, a right driven part, a left connecting part and a right connecting part; the synchronous lifting mechanism is characterized in that: the synchronous lifting mechanism also comprises a coder and a clutch; the left end of the active part is connected with the left driven part by the left connecting part; the coder is arranged on the left driven part; the right end of the active part is connected with the left end of the clutch by the right connecting part; and the right end of the clutch is connected with the right driven part. The synchronous lifting mechanism has a stable structure and simple operation, can reduce the complexity of a control system, effectively control the cutting distance and has low cost; two ends of the synchronous lifting mechanism are synchronously lifted through a mechanical connecting rod to effectively control the failure rate of a machine; and through the control of the on-off of the clutch, a front beam provided with a plurality of cutting torques is adjusted, can cut both a flat steel plate and an oblique steel plate and has wide application range.

Description

technical field [0001] The invention belongs to the technical field of thermal cutting equipment, in particular to a synchronous lifting mechanism of a straight multi-torque cutting machine. Background technique [0002] When the equipment is thermally cut, the steel plate that needs to be cut is not necessarily a regular shape. After being placed, there is often a certain inclination angle. At this time, the cutting torch needs to be adjusted to suit it. In the prior art, The lifting adjustment of the cutting torch is usually achieved by using two DC geared motors or two servo motors to control two sets of lifting mechanisms for lifting and moving, but each has its own advantages and disadvantages: the former is guaranteed by electrical control, but the synchronization Poor and prone to tilt; the latter has higher requirements for electrical configuration and high cost, and is not suitable for large-scale applications.
