Flared tube and joint tightening machine

Abstract

The invention discloses a flared tube and joint tightening machine. The problems that the mode of manually tightening a flared tube and a joint is high in labor intensity, high in rejection rate and low in assembly efficiency in the prior art are solved. The flared tube and joint tightening machine comprises a support seat, a nut clamping mechanism, a joint clamping mechanism and a power mechanism; a nut at one end of the flared pipe is fixed through the nut clamping mechanism,the joint is fixed through the connector clamping mechanism, thus, the joint cannot rotate and can move in the radialdirection along with the nut, and the power mechanism is arranged to drive the nut clamping device to rotate and further drive the nut to rotate, and the nut and the joint are tightened; when the nuttightening pressure reaches a preset value, the power mechanism stops working, the nut does not continue to be tightened any more, semi-automatic tightening of the flared tube and the joint can be achieved, the workload of an operator can be reduced, the assembly efficiency can be improved, the assembly quality can be guaranteed, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of flared pipes, in particular to a flared pipe joint tightening machine. Background technique [0002] The structure of the tightening of the flared steel pipe joint is that the outer tapered surface of the joint and the inner tapered surface of the flared pipe are in contact with each other, and the inner and outer tapered surfaces are pressed into contact by rotating the nut on the flared pipe. Therefore, it is not possible to use ordinary air tools to turn the joint to tighten the flared pipe joint. At present, the joint is fixed at one end, and the other end is manually tightened with an open end wrench on the booster rod. It requires high experience and physical strength for operators. [0003] There are problems in the prior art: one is that the diameter of the flaring pipe is 42 mm, and the opposite sides of the joint and the nut are 55 mm and 60 mm, respectively, so the manual tightening force is ...

AI Technical Summary

Problems solved by technology

[0003] There are problems in the prior art: one is that the diameter of the flaring pipe is 42mm, and the opposite sides of the joint and the nut are 55mm and 60mm respectively, so the manual tightening force is relatively large, and the labor intensity of pure manual screwing is high and the efficiency is low

Second, the requirements for the cooperation between the outer conical surface of the joint and the inner conical surface of the flared pipe are high, and the manual tightening torque and tightening force and tightening angle are not up to the standard, often causing subsequent oil leakage
