When each part of the equipment arrives at the assembly workshop, the assembly personnel need to take the drawings to check whether all the electrical control cabinets, electrical bottom plates, electrical panels, button boxes, electrical accessories, etc. The size is suitable and the quality is qualified. Whether the preset wire hole size during the assembly of the control cabinet is appropriate or not, after the inspection is correct, the electrical assembler needs paint spraying and the electrical panel needs screen printing.
In addition, before assembling the electric control cabinet, it is very important to prepare all the materials for assembly, including all kinds of equipment, components and accessories needed for assembly, as well as a tool kit, which contains various assembly tools such as screwdrivers, pliers and wrenches. Measure the length of the trunking and guide rail according to the layout of the bottom plate in the electrical drawing, and cut it with a saw bow. It should be noted that the trunking should be placed in a flat place, the guide rail should be clamped with a vise saw, and the joints should be flat.
Demonstration of assembly process scheme
In the assembly process, the stress position of parts should be appropriate and reasonable, which has an important impact on the assembly quality. According to the connection between the ball bearing of F3 14U and the drive shaft, if the bearing is simply struck by the same punch symmetry method in the process of interference fit, it is likely that a certain inclination angle will be generated due to striking, which will affect the assembly quality. In order to prevent this from happening, the bearing punch can be used as a buffer medium to keep the stress on the parts as balanced as possible.
In the process of bearing disassembly, the stress position should be concentrated in the inner ring as much as possible to achieve the purpose of stress balance, improve the service life of parts and make the operation of mechanical equipment safer and more reliable. Due to the requirements of mechanical equipment design and assembly process, some parts themselves have a certain taper.
