Man-machine isolated automatic milling shaping machining system and method

Abstract

The invention provides a man-machine isolated automatic milling shaping machining system and method. The machining system comprises a control system, a vision system, a truss mechanical hand, an end cover detachment machine, a milling shaping machining machine and a thread cleaning machine. During machining, firstly, the control system controls the truss mechanical hand to carry a to-be-shaped engine to the end cover detachment machine; secondly, the end cover detachment machine is controlled to position and lock the engine, and after end covers at the two ends are detached, the truss mechanical hand is controlled to carry the end-cover-detached engine to the milling shaping machining machine, and milling machining is conducted on the engine; and finally, the truss mechanical hand carriesthe engine, where end face shaping is finished, to the thread cleaning machine, and the end faces of the two ends of the engine are cleaned. Man-machine isolation, full-process automation and informatization are introduced into the field of the milling shaping machining system for the first time, and application prospects are very wide.

Description

technical field [0001] The invention belongs to the field of automatic processing, and in particular relates to a human-machine isolation automatic milling and shaping processing system and method. Background technique [0002] Solid propellant charge shaping is widely used in the pyrotechnics industry, and it is used in the shaping process of the engine end face after pouring. After the solid propellant is poured and solidified, its end face and cavity face should be trimmed, which is called "reshaping". With the continuous improvement of missile weapons' requirements on the energy performance of solid propellants, the drug type and drug surface shape are becoming more and more complex. Secondly, various forms of polymer materials are used in solid propellants, which are very sensitive to thermal stress, friction, impact force, and static electricity accumulation caused by various factors, and are prone to deflagration accidents. These factors have greatly increased the d...

AI Technical Summary

Problems solved by technology

The accuracy consistency of this method of manual trimming of complex profiles cannot be guaranteed, and if a slight carelessness causes "over-cutting", it will lead to losses

Manual removal of the end cap, the removal torque cannot be precisely controlled, the torque varies from person to person, cannot be quantitatively controlled, and the risk factor is high

Manual cleaning, the cleaning tool is used to scrape off the residual drug at the root of the thread, the operation safety and cleaning consistency are low

There are many manual control factors in the whole shaping process, and the safety degree is low

Moreover, in this shaping method, the operator is in direct contact with the engine, there is a hidden danger of accidents, and deflagration accidents are prone to occur, causing casualties to processing personnel.

According to the statistics of solid propellant accidents at home and abroad, the accident rate in the shaping process is as high as 28%.
