Abstract
The invention discloses a commutator. The commutator comprises commutating copper sheets which are evenly distributed on the outer circumference of a commutator body, wherein the commutating copper sheets and the commutator body are formed integrally through press pouring, and the commutating copper sheets are provided with sheet pins which are inserted in the commutator body, so that the commutating copper sheets and the commutator body are firmly combined. The commutator is characterized in that a plurality of reinforcing pins are arranged on the surface of the inner side of the sheet pins in the height direction of the commutating copper sheets, the reinforcing ribs of the adjacent sheet pins are staggered mutually in the height direction of the commutating copper sheets, and mutual interference between the reinforcing ribs of the adjacent sheet pins is avoided. According to the commutator, the radial size is small, the number of the commutating copper sheets is large, the requirement for high speed is met, the strength of combination between the commutating copper sheets and the commutator body can be improved, and the mechanical property of commutator products is improved.
Description
[technical field]
The present invention relates to be a kind of commutator product improvement invention.
[background technology]
Commutator is used widely in motor, electric tool product, the essential structure of commutator 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 strengthening the bond strength between commutation copper sheet and commutator body, improve the mechanical performance of commutator product, the maximum method of current employing be improve sheet pin structure and reinforcing ring is set, improving the optimal technical scheme of sheet leg structure is then the size adding large stretch of pin.But the commutator product less for radial dimension, commutation copper sheet sheet number is more, its sheet pin size is at circumferencial direction and be all subject to strict restriction in the radial direction, spacing between inside the sheet pin of each adjacent commutation copper sheet can be very little, if add the radial direction size of large stretch of pin, so contact with very easily colliding during commutator body together pressure injection at commutation copper sheet between adjacent sheet pin, thus cause the commutator product percent defective after injection-compression molding to remain high.
[summary of the invention]
For the deficiencies in the prior art, the object of the invention is to be to provide a kind of special less for radial dimension, commutation copper sheet sheet number is more and have the product of high-speed demand and design, the bond strength between commutation copper sheet and commutator body can be strengthened, improve the commutator of product mechanical performance.
For solving the problems of the technologies described above, the present invention takes following technical scheme:
A kind of commutator, 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: the inner surface of described pin is provided with some reinforcement pin along the short transverse of commutation copper sheet, mutually staggers non-interference between the reinforcement pin of adjacent sheet pin in the short transverse of commutation copper sheet.
Adopt the commutator of technique scheme, the setting strengthening pin is equivalent to the radial direction size increasing sheet pin, so strengthen the bond strength between commutation copper sheet and commutator body to a great extent, improve product mechanical performance, simultaneously, due to adjacent commutation copper sheet sheet pin reinforcement pin between due to setting of staggering up and down, avoid so non-interference and contact with colliding during commutator body together pressure injection at commutation copper sheet, ensure that the quality of commutator product.Therefore, the present invention can be suitable for that radial dimension is less, commutation copper sheet sheet number is more very well and have the commutator product of high-speed demand.
As preferably, the inner surface of described pin has upper, on the upper side, on the lower side and lower four positions can arrange reinforcement pin along the short transverse of commutation copper sheet, 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 arranges two and strengthens pin in two positions upper and on the lower side, the sheet pin inner surface of described commutation copper sheet B arranges two and strengthens pin in partially upper and lower two positions.
As preferably, described pin and strengthen pin and all have T-shaped cross-sectional structure, the centre of described pin offers elongated hole.

The present invention has following accompanying drawing:
Fig. 1 is structural representation of the present invention;
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 structure chart of commutation copper sheet B;

[embodiment]
Drawings illustrate technical scheme of the present invention 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, a kind of commutator of the present invention, 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, the inner surface of described pin 2 is provided with some reinforcement pin 3 along the short transverse of commutation copper sheet, mutually stagger in the short transverse of commutation copper sheet between the reinforcement pin 3 of adjacent sheet pin non-interference, concrete structure is: on the inner surface of described pin 2 has along the short transverse of commutation copper sheet, on the upper side, on the lower side and lower four positions can be arranged strengthens pin 3, 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 arranges two and strengthens pin 3 in two positions upper and on the lower side, sheet pin 2 inner surface of described commutation copper sheet B arranges two and strengthens pin 3 in partially upper and lower two positions.Described pin 2 and reinforcement pin 3 all have T-shaped cross-sectional structure (see Fig. 5), and the centre of described pin 2 offers elongated hole 4.
Above-mentioned commutator product, the setting of each reinforcement pin increases the radial direction size of sheet pin, the bond strength between commutation copper sheet and commutator body can be strengthened to a great extent, improve the mechanical performance of commutator product, simultaneously, to stagger up and down between reinforcement pin due to adjacent commutation copper sheet sheet pin setting, avoid so non-interference and contact with colliding during commutator body together pressure injection at commutation copper sheet, ensure that the quality of commutator product.Therefore, the present invention can be suitable for that radial dimension is less, commutation copper sheet sheet number is more very well and have the commutator product of high-speed demand.
