Abstract
The utility model discloses Hooked reverser, the commutation copper sheet that the excircle being included in commutator body is evenly laid, described commutation copper sheet is together with commutator body injection-compression molding, described commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded, it is characterized in that: described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body, the sheet pin inner surface of described commutation copper sheet A is provided with reinforcement pin, the sheet pin inner surface of described commutation copper sheet B does not establish reinforcement pin.Hooked reverser of the present utility model has higher mechanical strength and hypervelocity performance.
Description
[technical field]
The utility model relates to a kind of improvement invention of Hooked reverser product.
[background technology]
Hooked reverser is used widely in motor, electric tool product, the essential structure of Hooked reverser is: the commutation copper sheet that the excircle being included in commutator body is evenly laid, described commutation copper sheet is together with commutator body injection-compression molding, and described commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded.For improving mechanical strength and the hypervelocity performance of Hooked reverser product, the best way arranges reinforcement pin at the inner surface of sheet pin, but it is less for radial dimension, the Hooked reverser product that commutation copper sheet sheet number is more, Hooked reverser there is no suitable space in the radial direction to arrange reinforcement pin, reason has: one is that distance between adjacent reinforcement pin can be very near, easy contact of colliding when commutator pressure injection, two be strengthen the space of pin periphery can be very little, be unfavorable for the filling of commutator bulk material, affect commutator shaping after the structural stability of commutator body.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Hooked reverser improving mechanical strength and hypervelocity performance.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
Hooked reverser, the commutation copper sheet that the excircle being included in commutator body is evenly laid, described commutation copper sheet is together with commutator body injection-compression molding, described commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded, it is characterized in that: described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body, the sheet pin inner surface of described commutation copper sheet A is provided with reinforcement pin, and the sheet pin inner surface of described commutation copper sheet B does not establish reinforcement pin.
Described pin and reinforcement pin all have T-shaped cross-sectional structure, and the centre of described pin and reinforcement pin all offers elongated hole.
The Hooked reverser of technique scheme, its maximum innovation has the commutation copper sheet A strengthening pin and the commutation copper sheet B not strengthening pin to be crisscross arranged, that strengthens pin arranges the mechanical strength and hypervelocity performance that can improve Hooked reverser product to a certain extent, also solve simultaneously and strengthen pin the problem brought is set: one be distance between adjacent reinforcement pin can from must away from, contact of can not colliding when commutator pressure injection; Two is strengthen pin periphery can leave larger space, is not only beneficial to the filling of commutator bulk material, and effectively can improves the structural stability of commutator body.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structure chart of commutation copper sheet A;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is the structure chart of commutation copper sheet B;
Fig. 6 is the left view of Fig. 5.
[embodiment]
Drawings illustrate the technical solution of the utility model and embodiment, further describe each details and the operation principle thereof of embodiment below more by reference to the accompanying drawings.
As shown in the figure, Hooked reverser of the present utility model, the commutation copper sheet that the excircle being included in commutator body 1 is evenly laid, described commutation copper sheet is together with commutator body 1 injection-compression molding, described commutation copper sheet is provided with sheet pin 2 and implants in commutator body 1 and commutator body 1 strong bonded, described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body 1, sheet pin 2 inner surface of described commutation copper sheet A is provided with strengthens pin 3, sheet pin 2 inner surface of described commutation copper sheet B is not established and is strengthened pin 3.Described pin 2 and reinforcement pin 3 all have T-shaped cross-sectional structure, and the centre of described pin 2 offers elongated hole 4, and the centre of described reinforcement pin 3 offers elongated hole 5.
Above-mentioned Hooked reverser product, the commutation copper sheet A strengthening pin and the commutation copper sheet B not strengthening pin is had to be crisscross arranged, that strengthens pin arranges the mechanical strength and hypervelocity performance that can improve Hooked reverser product to a certain extent, also solve simultaneously and strengthen pin the problem brought is set: one be distance between adjacent reinforcement pin can from must away from, contact of can not colliding when commutator pressure injection; Two is strengthen pin periphery can leave larger space, is not only beneficial to the filling of commutator bulk material, and effectively can improves the structural stability of commutator body.
