Coupling numerical control machining machine tool

Abstract

The invention relates to a coupling numerical control machining machine tool. The machine tool comprises a body and a shell. A first main spindle box, a tailstock, a second main spindle box and a saddle are arranged on the body. The first main spindle body and the second main spindle box are provided with a first main spindle box body and a second main spindle box body correspondingly. A first main spindle and a second main spindle are mounted on the first main spindle box body and the second main spindle box body correspondingly. A first hollow hydraulic chuck and a second hollow hydraulic chuck are mounted at the front ends of the first main spindle and the second main spindle correspondingly. The tailstock is arranged between the first main spindle box and the second main spindle box. The saddle is arranged on one side of the body. A first tool holder and a second tool holder are fixed to the saddle. The first tool holder is arranged between the first main spindle box and the tailstock. The second tool holder is arranged between the second main spindle box and the tailstock. Supporting legs are arranged on the body. All coupling machining procedures can be completed without needing to change tools, the efficiency is improved, the time is saved, and the cost is lowered.

[0002] Tubing coupling is an important tool for oil field drilling and an essential part of tubing connection. The annual demand for couplings in China's petroleum equipment industry is tens of millions, and the output value is more than one billion yuan. However, China's existing coupling production equipment A large number of workers are required to complete production, processing, inspection and other processes. Machine tool processing is operated by workers, which has poor precision, high scrap rate, high energy consumption, low efficiency of manual packaging, poor production flexibility, and can only produce a single product. At the same time, each Manual handling is required between processes, and the efficiency is low. Especially when processing different-diameter couplings and special couplings, the process is cumbersome, the waste is time-consuming, the precision is poor, and the quality is not good enough, resulting in a short service life of the coupling and prone to failure. Oil and gas leakage occurs, which seriously affects the safety and production efficiency of oilfield operations. A steel pipe coupling processing equipment with a patent number of 201821268260.7 discloses a steel pipe coupling processing equipment, including a loading and unloading robot, a threading machine, a coding machine, Conveying device, thread inspection platform, magnetic particle flaw detection device, and basket loading robot. The loading and unloading robot can connect with the threading machine and take and send steel pipe couplings to the threading machine, and the loading and unloading robot can dock with the coding machine and connect the steel pipe. The hoop is sent to the coding machine, and the coding machine is connected with the magnetic particle flaw detection device through the conveying device. Docking and grabbing the steel pipe couplings after the flaw detection is completed. This equipment uses two threading machines. There are many processes, and all the processing processes cannot be completed on one equipment. The equipment invests a lot, takes up a lot of space, and is inconvenient to operate.
