Technical field

The utility model relates to punching technical field, in particular to a kind of rotor punching.

Background technique

Rotor is the rotary part in motor, and the iron core of rotor is suppressed by multi-disc rotor punching closed assembly.

Currently, the Chinese patent of Publication No. CN203522367U discloses a kind of rotor punching, including punching ontology, punching At least four composite permanent magnet slot is uniformly provided on piece ontology, composite permanent magnet slot is equipped with outside among magnetic magnetic bridge, punching ontology It is provided with the shaft hole for connecting shaft, which is equipped with keyway.

Above-mentioned rotor punching monnolithic case is in disc-shaped, when multiple rotor punchings are stacked together and are not squeezed, It is easy to appear offset between adjacent punching, causes the composite permanent magnet slot in adjacent punching to deviate, to influence the formation of rotor.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of rotor punching, by It is positioned when punching stacks, to achieve the purpose that precisely to install.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of rotor punching, packet Yoke portion is included, the yoke portion is equipped with multiple tooth sockets, and multiple tooth sockets are circumferentially evenly distributed on the edge in yoke portion, set among the yoke portion There is axis hole, limit hole, convex block compatible with limit hole are additionally provided in the yoke portion, the limit hole runs through yoke portion, the limit Position hole possesses to be cooperated with the convex block in adjacent rotor punching.

Through the above technical solutions, rotor punching, when stacking, face is away from latter where the convex block of preceding a piece of rotor punching Convex block on piece rotor punching is in front of the convex block of rear a piece of rotor punching is inserted into the limit hole of a piece of rotor punching The flush of convex block end face and preceding a piece of rotor punching yoke portion in limit hole, so that convex block will not influence the flat of rotor punching Whole degree can also make to be fixed together between adjacent rotor punching with the cooperation of corresponding limit hole, make after stacking by convex block When continuous rotor punching, the part rotor punching for stacking completion is not easy the movement for occurring opposite.

Preferably, there are two the convex blocks, two convex blocks are symmetricly set on the two sides of axis hole, and there are two the limit holes, Two limit holes are symmetricly set on the two sides of axis hole.

Through the above technical solutions, adjacent rotor punching, after completing to fix, there are two the positions of connection and is symmetrical arranged, The effect for reinforcing connection, further decreases a possibility that relatively moving between adjacent rotor punching.

Preferably, the edge of the axis hole is equipped with the first keyway, the second keyway, the shape and second of first keyway The shape of keyway is identical, and the center of the first keyway is hung down to the line in the axis hole center of circle and the line in the second key slot center to the axis hole center of circle Directly, line of the line at two limit hole centers perpendicular to two convex block centers.

Through the above technical solutions, between adjacent rotor punching when stacking, by the first keyway of previous rotor punching It is opposite with the second keyway of latter rotor punching, at this time the convex block of latter rotor punching just with the limit hole phase of previous rotor punching It is right, facilitate the positioning for carrying out convex block and corresponding limit hole, makes to stack rotor punching quicker.

Preferably, the side wall of the limit hole is equipped with inclined-plane, and the inclined-plane is in limit hole in same yoke portion The side of convex block.

Through the above technical solutions, convex block exists when the convex block on latter rotor punching will be installed on previous rotor punching The side wall of limit hole can be touched when being inserted into limit hole, and enters limit hole along inclined-plane, so that staff is in installation rotor punching Convex block accurately very need not be directed at corresponding limit hole when piece, staff is facilitated to operate.

Preferably, multiple through-holes are additionally provided in the yoke portion, multiple through-holes are circumferentially evenly distributed on tooth socket and limit around axis hole Between the hole of position.

Through the above technical solutions, reducing the quality of single rotor punching, saving processes raw material, and is installed to reduce After the quality of entire rotor afterwards reduces and rotates the energy that entire rotor needs to consume, and through-hole can increase rotor molding Heat dissipation area, improve radiating efficiency.

Preferably, the tooth socket is equipped with opening in the peripheral outer wall in yoke portion.

Through the above technical solutions, being formed between adjacent sheaves for being wrapped in by coil around coiled coiling tooth When coiling tooth, coil can be entered directly in tooth socket by being open from side, and need not be perpendicularly inserted into tooth socket, when rotor is fixed When piece is combined into rotor, the thickness of rotor is larger, coil from side can more easily coiling on rotor.

Preferably, the width of the opening of the tooth socket is less than the width in tooth socket other positions.

Through the above technical solutions, coil, after coiling is in tooth socket, smaller due to being open, coil will receive the side of opening Wall stops and is not easy to deviate from from tooth socket, reinforces the structural stability of entire rotor.

In conclusion the utility model having the beneficial effect that in contrast to the prior art

1. making can between adjacent rotor punching by the way that two limit holes, two convex blocks matched with limit hole are arranged It is connected, is not easy to rotate between rotor punching；

2. by setting the first keyway, the second keyway, convenient adjustment rotor punching carried out when stacking on position, fastly Convex block is directed at corresponding limit hole by speed, accelerates the assembling speed of rotor.
