A threaded screwing mechanism for pipe-like fittings oriented to heavy mass and large length-to-diameter ratio

Abstract

The invention belongs to the assembly equipment for heavy-weight and large-length-diameter-ratio pipe fittings, in particular to a threaded screwing mechanism for heavy-weight and large-length-diameter pipe-like pipe fittings, including a fuselage and screwing devices respectively installed on the fuselage The power application mechanism, automatic positioning anti-torsion mechanism and automatic attitude adjustment mechanism can complete the positioning and attitude adjustment of the screwed assembly through the joint action of the cylinder and the electric cylinder, and complete all the attitude adjustment actions through the servo electric cylinder acting on the attitude automatic adjustment mechanism , through the action of the servo electric cylinder, the docking of the positioning and attitude adjustment is completed, and the torque output of the screw power applying mechanism is used to complete the actual screwing work through the servo motor, and each action is completed through the servo system and the displacement sensor. Monitoring and adjustment of relevant data such as motion and torque. The whole process of the work of the present invention is automatically completed without manual assistance, and high-precision actions such as positioning, adjustment, and movement are efficient, accurate, and safe.

Description

technical field [0001] The invention belongs to the assembly equipment of quasi-pipe fittings oriented to heavy mass and large length-to-diameter ratio, in particular to a threaded screwing mechanism of quasi-pipe fittings oriented to heavy mass and large length-to-diameter ratio. Background technique [0002] With the change of the international situation, the whole world is rapidly developing its own military industry. In the military industry, the thread screwing work of pipe fittings with heavy weight and large length-to-diameter ratio widely exists. Its assembly feature is high assembly accuracy. There are very high requirements for the positioning and posture of the screwed parts and screwed-in parts, and there are also very high requirements for the control of the tightening torque. Therefore, the thread screwing work of heavy-duty and large-length-to-diameter pipe fittings is very important for the assembly of corresponding products. key to success. [0003] For the...

AI Technical Summary

Problems solved by technology

[0004] Aiming at many deficiencies such as rough positioning, difficult attitude adjustment, low work efficiency, and high risk of operation in the thread screwing work of traditional heavy-weight and large-length-diameter-ratio similar pipe fittings, the purpose of the present invention is to provide a heavy-duty Thread screwing mechanism for similar pipe fittings with large aspect ratio
