Abstract
The utility model relates to a stator punching of a motor, in particular to a stator punching of a direct current motor. An assembled stator punching of a brushless direct current motor is assembled by a single chip lamination 1 along the peripheral direction; one side of each single chip 11 of the single chip lamination 1 is provided with a fastening chip 111, and the other side thereof is provided with a corresponding fastening chip groove 112; a self-locking groove 114 is also arranged below the fastening chip 111 of the single chip 11; a self-locking convex point 113 is arranged below thefastening chip groove 112 of the single chip 11; and the size of the self-locking groove 114 and the size of the self-locking convex point 113 are matched. The self-locking groove and the self-lockingconvex point are matched, the stator punching is combined for use with the original fastening chip and the fastening chip groove of the single chip so as to lead the connection in single chip lamination to have self-locking effect, and can be used without welding. The stator punching saves welding procedure, reduces cost and has simple production technique.
Description
Technical field
The utility model relates to a kind of motor stator punching, particularly a kind of DC motor stator punching.
Background technology
At present, existing brushless DC motor stator punching all is monolithics 11 (as Fig. 1) that the annular stator punching with a monoblock is designed to divide equally, and a side of each monolithic 11 is provided with a cramp 111, and opposite side is provided with corresponding cramp groove 112.Monolithic 11 is laminated to certain folded thick, it is folded 1 to form monolithic, and then each monolithic folded 1 is wound the line separately, and the monolithic folded 1 that will wind line afterwards along the circumferential direction carries out assembly unit (as Fig. 2).This structure must be welded after being assembled into the full annular stator punching, can be scattered otherwise monolithic is folded, can't use.Welding not only increases operation, and the heat affected area of welding also can have a negative impact to the electromagnetic performance of stator; This outside weld is the weak link of stator, once cracking will cause motor to damage.
The utility model content
The purpose of this utility model is to provide a kind of and need not welds, and simplifies the brshless DC motor split mounting type stator punching of production technology.
The utility model is achieved in that a kind of brshless DC motor split mounting type stator punching, along the circumferential direction assembled by monolithic folded 1, one side of each monolithic 11 of monolithic folded 1 is provided with a cramp 111, opposite side is provided with corresponding cramp groove 112, and cramp 111 belows of described monolithic 11 also are provided with a self-locking groove 114; Cramp groove 112 belows of monolithic 11 are provided with a self-locking salient point 113, and the size of self-locking groove 114 and self-locking salient point 113 matches.
The utlity model has following beneficial effect: self-locking groove of the present utility model and self-locking salient point match, and unite use with original cramp of monolithic and cramp groove, make the connection of monolithic between folded have the self-locking effect, need not weld and can use.Use the utility model and saved welding sequence, the performance impact of having avoided welding to cause has reduced cost, and the one-shot forming of the utility model monolithic, and technology is simple, and comparing original monolithic can not increase extra cost.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is existing single chip architecture schematic diagram;
Fig. 2 is existing stator laminating structure schematic diagram;
Fig. 3 is the utility model monolithic schematic diagram;
Fig. 4 is the utility model stator punching connection diagram;
Among the figure: 1 monolithic is folded, 11 monolithics, 111 cramps, 112 cramp grooves, 113 self-locking salient points, 114 self-locking grooves.
Embodiment
Referring to Fig. 3, Fig. 4.A kind of brshless DC motor split mounting type stator punching, along the circumferential direction assembled by monolithic folded 1, one side of each monolithic 11 of monolithic folded 1 is provided with a cramp 111, and opposite side is provided with corresponding cramp groove 112, and cramp 111 belows of described monolithic 11 also are provided with a self-locking groove 114; Cramp groove 112 belows of monolithic 11 are provided with a self-locking salient point 113, and the size of self-locking groove 114 and self-locking salient point 113 matches.
Self-locking groove of the present utility model and self-locking salient point match, and unite use with original cramp of monolithic and cramp groove, make the connection of monolithic between folded have the self-locking effect, need not weld and can use.Use the utility model and saved welding sequence, the performance impact of having avoided welding to cause has reduced cost, and the one-shot forming of the utility model monolithic, and technology is simple, and comparing original monolithic can not increase extra cost.
