Abstract
A fastening structure of a hollow rivet for a motor consists of an upper end cover, a lower end cover and the hollow rivet. The upper surface of a stator core is provided with the upper end cover, and the lower surface thereof is provided with the lower end cover; the hollow rivet penetrates out of the lower end cover and the stator core to be riveted with the upper end cover; and the lower end of the hollow rivet is provided with a counter bore, and the contact part between the upper end of the hollow rivet and the upper end cover is provided with 8 locking teeth. The riveted part adopts a whole-circle riveting mode, thus being attractive and firm and difficult to loose after riveting operation is completed. The depth of the counter bore is appropriate, thus being capable of effectively avoiding the influence of overlapped thickness deviation of the stator on riveting and fastening of the motor. The labor intensity is reduced, the riveting consistency of the motor is good and the quality is stable and reliable.
Description
Technical field: the utility model relates to a kind of fastening structure of motor air heart rivet.
Background technology: the motor fastening structure, generally adopt bolted, real core rivet is fastening, the hollow flange is fastening.Above structure fastening all exists such or such defective.Bolted needs 4-6 people's operation, and equipment is to adopt air compressor machine, special-purpose Pneumatic screw driver; Shortcoming is the material cost height, and four nut fastening forces are inhomogeneous, and man efficiency is low.Real core rivet is fastening, needs 1 people that four rivets are inserted motor to be tightened, and 1 people puts motor to riveting dress mould, and both hands are pressed down start button, finish the riveting dress; Equipment is to adopt 16 t hydraulic press, special-purpose riveting dress mould; Shortcoming is 3 contacts of caulking part, easily gets loose, and doing over again needs manual knocking or the pressure-off of particular manufacturing craft machinery, and end cap, stator piece are easily impaired.The hollow flange is fastening, needs 1 people that four rivets are inserted motor to be tightened, and 1 people puts motor to riveting dress mould, and both hands are pressed down start button, finish the riveting dress; Equipment is to adopt 16 t hydraulic press, special-purpose riveting dress mould; Shortcoming is that requirement stator semi-finished product size is accurate, otherwise the riveted joint position is yielding or get loose, and doing over again needs drilling machine to bore to remove to rivet flange.
Summary of the invention: the purpose of this utility model is exactly the fastening structure that a kind of motor air heart rivet will be provided, and it can overcome the existing problem of above prior motor fastening structure well.The purpose of this utility model is achieved in that the fastening structure of motor air heart rivet, is made up of upper end cover, bottom end cover, tubular rivet, it is characterized in that: be provided with upper end cover above the stator core, be provided with bottom end cover below; Tubular rivet passes bottom end cover, stator core, rivets with upper end cover; Described tubular rivet lower end is provided with counterbore, and upper end and upper end cover contact position are provided with 8 locking teeth.The utility model riveted joint position is the riveting of whole circle button, and riveting dress back is attractive in appearance fastening, is difficult for loosening.The suitable rivet counterbore degree of depth can be avoided the stator stack thickness deviation effectively, and riveting loads solid influence to motor.Labour intensity is low, motor riveting dress high conformity, and steady quality is reliable.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. upper end cover, 2. tubular rivet, 3. bottom end cover, 4. counterbore, 5. stator core, 6. locking tooth.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
The fastening structure of motor air heart rivet is made up of upper end cover 1, bottom end cover 3, tubular rivet 2, it is characterized in that: be provided with upper end cover 1 above the stator core 5, be provided with bottom end cover 3 below; Tubular rivet 2 passes bottom end cover 3, stator core 5, rivets with upper end cover 1; Described tubular rivet 2 lower ends are provided with counterbore 4, and upper end and upper end cover 1 contact position are provided with 8 locking teeth 6.During concrete enforcement, the counterbore of certain depth is processed in the tubular rivet lower end, upper end and upper end cover contact position are processed with 8 and lock teeth.By 1 people four rivets are inserted motor to be tightened, by 1 people motor is put to riveting dress mould, both hands are pressed down start button, finish the riveting dress.Equipment is to adopt 16 t hydraulic press, changes four dies with former riveting dress mould.As long as brill removes to lock the tooth hypotenuse, do not hinder end cap when doing over again, stator efficient height, labour intensity is low, motor riveting dress high conformity, steady quality is reliable.
