Pipe-fitting-like threaded screwing mechanism for heavy-weight and large length-diameter ratio

Abstract

The invention belongs to pipe-fitting-like assembly equipment for heavy-weight and large length diameter ratio, and particularly relates to a pipe-fitting-like threaded screwing mechanism for a heavy-weight and large length-diameter ratio. The pipe-fitting-like threaded screwing mechanism comprises a machine body, a screwing force applying mechanism installed on the machine body, an automatic positioning and anti-twisting mechanism in stalled on the machine body and automatic attitude adjusting mechanisms installed on the machine body. The positioning and attitude adjustment of the screwed assembly pieces are partially completed through the joint action of an air cylinder and an electric cylinder, all the attitude adjustment actions are fully completed through a servo electric cylinder acting on the automatic attitude adjustment mechanisms, the butt joint of the pieces to be screwed after positioning and attitude adjustment is completed through the action of the servo electric cylinder, the actual work of screwing is completed through the torque output of a servo motor acting on the screwing force applying mechanism, and the monitoring and adjustment of the action, torque and otherrelated data are completed by all actions through a servo system cooperating with a displacement sensor. According to the pipe-fitting-like threaded screwing mechanism, the whole project is automatically completed without manual assistance, and the high-precision actions of positioning, adjusting, moving and the like 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
