Description
Technical Field
The utility model relates to a motor installation technical field especially relates to a fan motor rivet structure.
Background
At present, the basic structure of a fan motor is formed by assembling a stator assembly, a rotor assembly and a large part of an end cover 3, and in the prior art, the end cover and the stator are generally assembled by using a screw and nut structure and adopting a manual or automatic screw driving machine. The structure has certain difficulty in process operation and is time-consuming and labor-consuming. And the screw structure can have the hidden danger of loosening under the long-term operation of motor, vibrations, and this patent produces based on this kind of defect.
The prior art has the following disadvantages:
firstly, the process is difficult to operate, each motor needs four sets of screws and nuts, the assembly needs a large amount of hands, and the repair and the disassembly are time-consuming and labor-consuming.
Secondly, the screw structure has the hidden trouble of loosening when the motor runs for a long time and vibrates.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects of the prior art that the assembly of the screw and nut structure for the end cover and the stator is inconvenient and the using effect is not good, and providing a rivet structure of a fan motor.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a fan motor rivet structure, includes stator core, arranges the end cover of stator core both sides in, first through-hole has been seted up to stator core, the second through-hole corresponding with first through-hole position is seted up to the end cover, first through-hole, second through-hole run through there is the rivet, end cover, stator core pass through rivet fixation together.
The first through hole comprises a first hole part and second hole parts arranged at two ends of the first hole part, the diameter of the first hole part is smaller than that of the second hole part, the second through hole is a flanging hole, the flanging hole is inserted into the second hole part, the inner diameter of the flanging hole is equal to that of the first hole part, and the outer diameter of the flanging hole is equal to that of the second hole part.
The utility model provides a pair of fan motor rivet structure, beneficial effect lies in: the device simplifies the assembly process, adopts the tool for one-time riveting, has high assembly efficiency, and avoids the hidden danger of loosening the end cover.
Drawings
Fig. 1 is a schematic view of an assembly structure of the present invention;
fig. 2 is a schematic structural view of the stator core of the present invention;
fig. 3 is a schematic structural view of fig. 2A-a of the present invention.
In the figure: end cover 1, hole flanging 2, rivet 3, stator core 4, first hole portion 5, second hole portion 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a rivet structure for a fan motor comprises a stator core 4 and end covers 1 arranged on two sides of the stator core 4, wherein a first through hole is formed in the stator core 4, a second through hole corresponding to the first through hole is formed in the end covers 1, a rivet 3 penetrates through the first through hole and the second through hole, and the end covers 1 and the stator core 4 are fixed together through the rivet 3.
The device simplifies the assembly process, adopts the tool for one-time riveting, has high assembly efficiency, and avoids the hidden danger of loosening the end cover.
As a preferred embodiment: first through-hole includes first hole portion 5, arrange the second hole portion 6 at first hole portion 5 both ends in, first hole portion 5 diameter is less than second hole portion 6 diameter, the second through-hole is hole flanging 2, hole flanging 2 is inserted and is established in second hole portion 6, the internal diameter of hole flanging 2 equals with first hole portion 5 diameter, the external diameter of hole flanging 2 equals with second hole portion 6 diameter, the unanimous bending deformation can not be guaranteed after rivet riveting of first hole portion 5 internal diameter and rivet external diameter, adopt hole flanging structure installation simultaneously, the guidance quality is good, be convenient for the butt joint of end cover and stator core, joint strength is higher.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model thereof, the technical solution, concept and design obtained by equivalent replacement or change should be covered within the protection scope of the present invention.
