An automatic torquer for steel cylinder valves

Abstract

The invention provides an automatic torquer for steel cylinder valves. The automatic torquer comprises an upper twisting mechanism and a lower fixing mechanism. The upper twisting mechanism comprises a motor, a reduction box, a balancing weight, a torque sensor, a rotating unit and a chuck, wherein the motor is connected with the reduction box, one end of the reduction box is connected with the balancing weight via a steel rope and the other end of the reduction box is connected with the torque sensor via a shaft, the torque sensor is connected with the rotating unit and the rotating unit is connected with the chuck. The lower fixing mechanism is a clamping device. The automatic torquer for steel cylinder valves has the advantages that a steel cylinder tightening process is controlled mechanically and automatically, so that manual judgment is not needed, the phenomena of excessive tightening and thread damage are prevented, gas leak caused by looseness of valves is prevented, machine fatigue is prevented and the efficiency is increased.

Description

technical field [0001] The invention belongs to the field of filling gas cylinders, and in particular relates to an automatic torque device for cylinder valves. Background technique [0002] When the traditional gas cylinder loading and unloading machine tightens the valve, it is determined whether the cylinder valve is fastened in place by experience or by looking at the number of threads of the thread. During operation, it is completely subjective, and the valve will either be too loose or leak, or Too much tightening will damage the thread, and the effect will be slow. In many cases, the inspection is done manually by workers to check whether it is qualified again. This not only has high requirements for workers, but also is not efficient. Contents of the invention [0003] In order to solve the above problems, the present invention provides a cylinder valve automatic torque device, the specific technical scheme is as follows: [0004] An automatic torque device for st...
