Abstract
The utility model discloses a commutator commutation sheet which is characterized in that the commutator commutation sheet is composed of a sheet body, a hook, upper hook feet, lower hook feet and side hook feet. There are two upper hook feet which are symmetrically arranged on the two sides of the hook arranged on the top part of the sheet body. There are two lower hook feet which are symmetrically arranged on the bottom part of the sheet body. There are two side hook feet which are arranged on the two sides of the sheet body. The upper and lower hook feet are hook-shaped. The side hook feet are dovetail-shaped. The sheet body, the hook, the upper hook feet, the lower hook feet and the side hook feet are casted into an integrated whole. Bonding strength between the commutator commutation sheet and a commutator body is high so that product mechanical strength is increased, product over-speed performance is enhanced and thus the commutator commutation sheet is quite applicable to large-scale commutators.
Description
Technical field
The utility model relates to commutator technical field, is specifically related to the commutator segment of commutator.
Background technology
Commutator is mainly used on electric tool, and the Key Performance Indicator of commutator refers to its hypervelocity performance, and hypervelocity performance high commutator can ensure product quality, improves product useful life.Possesses high hypervelocity performance, first product will have high mechanical strength, it is high to be that bond strength between commutator segment and commutator body is wanted, commutator segment adopts drawing section bar or copper shell to make mostly at present, the commutator segment of drawing section bar is to carry out combination by dovetail and commutator body, dovetail is located at the medial surface of commutator segment lamellar body, and the commutator segment of copper shell is to carry out combination by hook pin and commutator body, and hook pin is located at top and the bottom of commutator segment lamellar body.On the whole, said structure commutator segment is for large-scale commutator, and the adhesion between commutator segment and body is limited, can not possess very high mechanical strength, thereby can not meet well the hypervelocity performance requirement of product.
Summary of the invention
In view of the deficiencies in the prior art, the technical problems to be solved in the utility model is to be to provide the bond strength between a kind of and commutator body high, increases product mechanical strength, improves product hypervelocity performance, is specially adapted to the commutator segment of large-scale commutator.
The utility model takes following technical scheme to complete:
Commutator segment, it is characterized in that: formed by lamellar body, crotch, the pin of rising to the bait, lower hook pin and side hook pin, the described pin of rising to the bait is provided with two, crotch bilateral symmetry at lamellar body top arranges, described lower hook pin is also provided with two, be symmetrical arranged in lamellar body bottom, described side hook pin is provided with two, arranges in lamellar body both sides.Described upper and lower hook pin is coupler body shape, and described side hook pin is swallowtail shape.
Adopt the commutator segment after technique scheme, it is different from traditional commutator segment, it has upper and lower hook pin and side hook pin and commutator body simultaneously and carries out combination, particularly the design of side hook pin has broken through traditional commutator segment structure, upper and lower hook pin is coupler body shape in addition, side hook pin is swallowtail shape, and upper and lower hook pin and side hook pin all arrange two, adhesion between the commutator segment of said structure and commutator body is very strong, compare tradition and can improve bond strength more than 20%, thereby increase product mechanical strength, can meet better the hypervelocity performance requirement of large-scale commutator product.
As preferably, described lamellar body, crotch, the pin of rising to the bait, lower hook pin and side hook pin are single-casting.
Brief description of the drawings
The utility model has the following drawings:
Fig. 1 is the structure chart of commutator segment of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Embodiment
As shown in the figure, commutator segment of the present utility model, formed by lamellar body 1, crotch 2, the pin 3 of rising to the bait, lower hook pin 5 and side hook pin 4, described lamellar body 1, crotch 2, the pin 3 of rising to the bait, lower hook pin 5 and side hook pin 4 are single-casting, described in the pin 3 of rising to the bait be provided with two, in the crotch 2 bilateral symmetry settings at lamellar body 1 top, described lower hook pin 5 is also provided with two, be symmetrical arranged in lamellar body 1 bottom, described side hook pin 4 is provided with two, arranges in lamellar body 1 both sides; Described pin 3 and the lower hook pin of rising to the bait is 5 coupler body shapes, and described side hook pin 4 is swallowtail shape.
