Use stack mounting face plate, plug-in unit, insert component of box, electron, parts of an apparatus and mechanical spare parts and component, make its make the installation case of a whole. Machine ark is mixed by frame cover board (the door) composition, have the appearance of cuboid commonly, be born is placed. It is the environment that regular job provides electronic equipment to suit and safety to defend. This is to be next to the one class of systematic level to assemble. Do not have close machine ark of the structure calls frame.
The technology asks ① should have good specifications. The structure of machine ark should be mixed according to the electric, mechanical function of equipment the requirement of use environment, undertake necessary physical design and chemical design, in order to make sure the structure of machine ark has good stiffness and intensity and good electromagnetism segregation, ground connection, noise segregation, ventilated medicinal powder the function such as heat. In addition, machine ark should be had resist vibration, fight concussion, anti-corrosive, dustproof, waterproof, radiation-proof wait for function, so that make sure equipment is stable and reliable,the ground works. ② should have good use sex and safe safeguard, facilitating operation, installation and maintenance, can make sure handlers is safe. ③ should facilitate production, assemble, debug and pack carry to be defeated. ④ should up to standard is changed, the requirement of normalization, seriation. Beautiful, applicable, colour coordinates ⑤ modelling.
The machine ark that inchoate place uses main type and structure is to use cast or angle iron classics to bolt, rivet joins or solder mostly machine ark frame, increase the cover board that makes by thin stencil steel again (the door) and into. The bulk of ark of this kind of machine big, cumbersome, appearance is pallet, already was washed out. As the use of transistor, integrated circuit and the subminiaturization of all sorts of component, parts of an apparatus, the structure of machine ark also develops to direction of miniaturization, unitization. Machine ark already became those who have certain measure series to insert structure of box, plug-in unit by the development of structure of full face plate in the past. The assembly that inserts box, plug-in unit ranges way cent level is arranged and perpendicular arrange two kinds. The steel profile that machine ark material uses all sorts of thin stencil steel, section figure generally, aluminous profile and all sorts of projects are plastic wait. The frame of machine ark is divided with solder, outside bolt join, still use stick receive technology.
Machine ark presses component part bearing, what material reachs its workmanship is different, can divide for profile and thin plate two kinds of basic structures.
Ark of machine of ① profile structure: Ark of machine of profile having steel and ark of aluminous profile machine two kinds. Ark of machine of steel body ability is pillar composition by different seamless steel tube. The stiffness of ark of this kind of machine and intensity are very good, apply to heavy equipment. The ark of aluminous profile machine that comprises by aluminium alloy profile has certain stiffness and strength, apply to general or Portable Plant. Weight of ark of this kind of machine is light, treatment capacity is little, the shell is beautiful, get applied extensively.
