Abstract
The invention relates to a block type iron core structure and a circle forming method, and belongs to the technical field of manufacture of electric motors. The sectional type iron core structure comprises a block stator core (1) of which two ends are provided with connecting convex parts (101) and connecting concave parts (102), the connecting convex parts (101) and the connecting concave parts (102) of adjacent block stator cores (1) are mutually embedded to form circles, and a hoop or a housing (5) is wrapped outside the circle formed block type iron core. The circle forming method comprises the following steps: A, mounting a busing on the block stator core (1), and winding the block stator core (1) to form a coil stator; B, preliminarily forming a circle manually through a movable loop based on the wound coil stator, and fixing the circle for standby; and C, pressing the coil stator into the hoop or the housing (5), so as to finish circle forming of the block stator core (1). The method has the advantages of reasonable design and convenient operation, can effectively improve comprehensive property and production efficiency of a motor, and ensure inner circle degree of the stator core, cylindrical degree and the like after the block stator core forms a circle.
Description
Technical field
The present invention relates to a kind of sectional type core structure and become circle method, belong to the manufacturing technology field of motor.
Background technology
Have stator core construction for motor now and become circle method various, have full circle, the chain type vertical bar is type, square, the structure of sectional type is also arranged, but more and more fierce along with market competition, the stator structure that everybody is lower in development cost, motor performance is good, existing sectional type stator core construction adopts the method for welding to reach into round purpose usually, when welding, produces a large amount of heats, have a strong impact on the insulation system of motor, thereby reduced the combination property of motor.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, easy to operate, can effectively improve the sectional type core structure of motor combination property and become circle method.
Sectional type core structure of the present invention comprises that the two ends band connects protuberance and the piecemeal stator core that is connected recess, the connection protuberance that it is characterized in that adjacent piecemeal stator core be connected the mutual chimeric back Cheng Yuan of recess, the sectional type iron core of Cheng Yuanhou is coated with anchor ear or casing.
The bottom of described piecemeal stator core also can be provided with empty like groove.
Also can be provided with alice on described anchor ear or the casing.
The one-tenth circle method of sectional type core structure of the present invention is undertaken by following processing step:
A, the piecemeal stator core is carried out lining install, the piecemeal stator core that installs lining is installed on the frock of spooling equipment and is winding into the line stator;
B, standby after the line stator after the coiling carried out that craft is preliminary and become circle to fix with movable anchor ear;
C, anchor ear or casing are put into into preheating in the sired results dress, tentatively become the fixing line stator of circle to put into in the sired results dress movable anchor ear then, take down movable anchor ear, the line stator is pressed in anchor ear or the casing, promptly finish the Cheng Yuan of piecemeal stator core.
The present invention compared with prior art has following outstanding advantage and good effect:
1, piecemeal stator core employing anchor ear or casing are as the method for Cheng Yuan, anchor ear or casing utilization reach powerful pulling force lastingly, make all inwardly cooperations under the effect of power of whole stator iron core tooth portion, make between Mosaic face cooperate tightr, the gap is littler, thereby the magnetic circuit influence to motor is minimum, makes every performance index of motor more perfect.
2, the piecemeal stator core because anchor ear or casing do not produce big heat at Cheng Yuanzhong, does not destroy the insulation system of motor becoming bowlder to adopt the method for anchor ear or casing Cheng Yuan, has improved the security reliability of motor greatly.And existing piecemeal stator core all adopts the technology of argon arc welding or laser welding, in welding process, all can produce big heat, the position of required welding decides what according to the number of teeth, complicated operation and efficient are not high, the big heat that produces is comparatively serious to the insulating barrier destruction of motor, can not guarantee the security reliability of motor.
3, each piecemeal stator core is under the effect of anchor ear or casing internal force, makes Mosaic face and Mosaic face, to be connected recess tightr with the relative engagement that is connected protuberance, thereby makes motor performance perfect more.It is simple in structure, and is easy to operate, not only greatly reduces manpower labour cost, has also improved motor production efficiency.Guaranteed that greatly the piecemeal stator core is in the interior round degree of Cheng Yuanhou stator core, cylindricity etc.
