The fixed frame for the magnetic pole assembly production line

Abstract

Design method for mounting bracket Abstract The invention relates to a design method for a mounting bracket for an assembly line for the magnet group. The method comprises arranging the mounting seat to have an isosceles-trapezoid-like shape, providing a second through hole matching the gap of the pillar at 5 each of four vertexs to the mounting seat, arranging the first through hole symmetrically near the long edge, arranging an interference fit between the first through hole and the sleeve, adjusting the coaxiality of the mounting cover and the first through hole by the gap between the second through hole and the pillar, arranging the first 10 and second shaft portion and the thread portion to be coaxial. Because the whole mounting bracket is fastened after the assurance of coaxiality of the through hole of the mounting seat and the mounting cover is made, so the rotating shaft do not shake during its rotating, the noise is reduced or eliminated. 202 202 201 Fig.3 , / ' )

Description

technical field [0001] The invention relates to the field of automatic assembly lines, in particular to a fixing frame for a magnetic pole group assembly production line. Background technique [0002] Patent document PCT / CN2014 / 081921 discloses a magnetic energy turntable, which is equipped with numerous magnetic pole group arrays, each magnetic pole group is composed of 16 pieces of permanent magnets arranged alternately with adjacent magnetic poles, and each magnetic pole group is artificially Due to the small size and thin thickness of each permanent magnet, manual assembly is difficult, inefficient, and error-prone, resulting in multiple permanent magnets attracting each other. In order to improve efficiency and eliminate time loss caused by errors, the factory adopts an automated assembly line to assemble the magnetic pole groups.

[0002] Patent document PCT / CN2014 / 081921 discloses a magnetic energy turntable, which is equipped with numerous magnetic pole group arrays, each magnetic pole group is composed of 16 pieces of permanent magnets arranged alternately with adjacent magnetic poles, and each magnetic pole group is artificially Due to the small size and thin thickness of each permanent magnet, manual assembly is difficult, inefficient, and error-prone, resulting in multiple permanent magnets attracting each other

In order to improve efficiency and eliminate time loss caused by errors, the factory adopts an automated assembly line to assemble the magnetic pole groups. However, in the production process, the conveying track often vibrates severely and the noise is large. After investigation, the cause of this phenomenon is the rotating shaft. Shaking during the rotation, the reason for the shaking of the shaft is that the coaxiality difference between the upper and lower through holes of the fixed frame, the shaft is forcibly assembled

The fixed frame currently used is made of non-magnetic stainless steel through punching and blanking, and then bent. Since these two steps are carried out separately, the coaxiality of the upper and lower through holes of the bent fixed frame will inevitably be affected. , without changing the process, improving the coaxiality of the upper and lower through holes requires sheet metal processing equipment with a relatively high manufacturing accuracy, which will inevitably lead to an increase in processing costs
