The utility model has fundamentally solved four class problems in rotor assembling:
1, balance weight is not annular, is kidney-shaped, and misplace up and down 180o and thickness difference.
2, because rotor core is embedded with magnet steel 28, rotor banding is compared with ferromagnetism.
3, riveting can not pine.
4, revolve rapidly and accurately the N root rivet that riveting is uniformly distributed along the circumference.
As shown in Figure 4, cylindrical has the closed assembly seat 1 of hatching knurling will be placed on one to revolve the upper assembling of riveting base plate (with 4), revolve riveting base plate and play stable and supporting role installation diagram of the present utility model.Stainless steel plug 2 is equipped with by screw 10 and spring washer 9 in the center of closed assembly seat 1, for accessories such as closed assembly balance weight 13,15, rotor core 27, rivet 26, pressure heads 3; Female spiral shell (M12) 8 of pressure head 3 and hexagonal flange is complete rotor 7 pre-pressings for the treatment of riveting of closed assembly.Revolve before riveting, closed assembly seat 1 is placed on revolving on riveting base plate 4 on machine together with rotor 7, revolves riveting base plate 4(by its kidney slot) and the fixation of riveter relative position.The round boss 14 of closed assembly seat 1 bottom will be put into the center hole that revolves riveting base plate 4, is beneficial to and riveter contraposition.Revolving riveting base plate 4 outer circular edge places has a positioning round orifice 12, for inserting alignment pin 5, to need to revolve the N root rivet of riveting on accurate calibration closed assembly seat 1.Cylindrical has the backing plate 6 of hatching knurling to be placed on closed assembly seat 1 and revolves between riveting base plate 4, the problem that has solved highly inconsistent (differing 6mm) when revolving riveting balance weight and revolving rivet on riveting rotor tip baffle plate 25, does not need to process each part product and all adjusts the stroke that revolves die.
Compared with prior art, its innovative point has the utility model:
1, closed assembly seat 1 bottom is local sink one, and balance weight 15 under kidney-shaped is abdicated in its position, and its height is identical with the thickness (8mm) of lower balance weight 15.In like manner, while using pressure head above, also to abdicate position and the thickness (6mm) of balance weight 13 on kidney-shaped.In addition, the manufactured head position in closed assembly seat bottom, also will sink one, and its position and height will be abdicated position and the thickness (1.9mm) of manufactured head.Revolve in riveting process, by picking and placeing backing plate, solved the inconsistent problem of height of rivet on riveting balance weight and baffle plate of revolving, so just the riveting of DC brushless motor band balance weight rotor is converted into the riveting of not being with balance weight rotor.
2, on closed assembly seat 1, the plug 2 through rotor adopts stainless steel bar, has avoided because rotor banding causes compared with ferromagnetism the demoulding difficulty that suction causes.
