Man-machine isolation automatic cover-disassembling and milling-shaping machining system and method

Abstract

The invention provides a man-machine isolation automatic cover-disassembling and milling-shaping machining system and method. The shaping machining system comprises a control system, a visual system,a truss mechanical arm, an end cover disassembling machine and a milling-shaping machining machine; during machining, the control system is used for controlling the truss mechanical arm to carry a to-be-shaped engine to the end cover disassembling machine according to the position information, collected by the visual system, of the to-be-shaped engine; then, the end cover disassembling machine iscontrolled to disassemble end covers of the two ends of the engine according to the set parameters; finally, the truss mechanical arm is controlled to carry the engine with the end covers disassembledto the milling-shaping machining machine, the milling-shaping machining machine is used for carrying out positioning and locking on the engine, and a milling main shaft cutter in the milling-shapingmachining machine is controlled to carry out milling on the end surfaces of the two ends of the engine according to the drawing requirement. According to the man-machine isolation automatic cover-disassembling and milling-shaping machining system and method, man-machine isolation, full-process automation and informatization are introduced into the field of milling-shaping machining systems for thefirst time, and the application prospect is 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 cover removal milling 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 incre...

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

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%.
