Description

[Detailed Description of the Invention] This invention relates to a control panel framework, and particularly to a control panel framework for accommodating a large number of unit control units.

Conventionally used control panel frameworks have many welded parts due to strength issues, and welding increases production man-hours and hinders mass production of component parts, resulting in poor productivity and uneconomical drawbacks. There were many.

Therefore, in order to improve the above-mentioned drawbacks, the purpose of this invention is to reduce the number of welded parts so as to satisfy the strength and to facilitate the assembly of standardized components by means of fastening members. The object of the present invention is to provide an economical control panel framework that improves productivity by reducing assembly man-hours and making it possible to mass-produce component parts.

To summarize this idea, a box frame is formed by attaching side plates to each side of the top frame and bottom frame, which are welded together into a nearly rectangular frame. The side plates of the panel are made of thin steel plates, and both ends in the width direction are bent into a U-shaped cross section to serve as vertical supports, and the side plates of the top frame and the bottom frame are placed at positions corresponding to the mounting holes of the side plates of the panel. A boss member with a tap hole is integrally formed on the
The board side plate is configured to be attached to the top frame and the bottom frame by screwing mounting bolts from the board side plate mounting hole to the tap hole of the boss member.
