Abstract
The utility model discloses roll type copper segment, it is characterised in that：With cylindrical housings, the top of cylindrical housings has larger outside diameter, the outer round surface of larger outside diameter is provided with the soldering bonding wire groove processed with milling tool, the endoporus hole wall of cylindrical housings is laid with the radial protrusion of multiple same shapes in a circumferential direction, cavity is crossed between adjacent radial projection, the width of cavity gradually broadens from the root of radial protrusion toward top-direction, is narrowed again after quickly being broadened when close to the top of radial protrusion to form necking；In the short transverse of cylindrical housings, the endoporus of cylindrical housings, which is provided with, cuts the upper annular groove processed and lower annular groove with lathe tool hook, and the upside cell wall and bottom land of upper and lower annular groove are rectangular, and downside cell wall and bottom land are in angle.The commutator that the utility model makes, technique simple structure intensity are high.
Description
Technical field
It the utility model is related to a kind of commutator, and in particular to a kind of roll type copper segment of commutator.
Background technology
In the prior art, the preparation method of most of commutators is first punching copper segment and then through cumbersome screening
Process, commutator, low production efficiency most is made through injection step afterwards.It is low to solve the punching of copper segment and screening efficiency
Problem, at present sometimes using the overall commutation chip architecture for rolling copper hull shape formula, but copper shell circularity is not enough, it is necessary to reserve foot
Enough allowance, high material consumption cost is high, and the hook that is formed of punching copper shell endoporus causes to be molded nor especially desirable
Adhesion after process between copper shell and phenolic moulding powder is weaker, and the structural strength of commutator is not high, it is impossible to adapts to high rotating speed work very well
It is required.
The content 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 a kind of making commutator
The high roll type copper segment of technique simple structure intensity.
The utility model is adopted the following technical scheme that to complete：
Roll type copper segment, it is characterised in that：With cylindrical housings, the top of cylindrical housings has outside larger
Circular diameter, the outer round surface of larger outside diameter are provided with the soldering bonding wire groove processed with milling tool, cylindrical housings
Endoporus hole wall is laid with the radial protrusion of multiple same shapes in a circumferential direction, and cavity is crossed between adjacent radial projection,
The width of cavity gradually broadens from the root of radial protrusion toward top-direction, after quickly being broadened when close to the top of radial protrusion
Narrow again to form necking；In the short transverse of cylindrical housings, the endoporus of cylindrical housings is provided with cuts processing with lathe tool hook
Upper annular groove and lower annular groove out, the upside cell wall and bottom land of upper and lower annular groove are rectangular, and downside cell wall and bottom land are in angle.
Described necking is shaped as dove tail shape.
After adopting the above technical scheme, realizing overall commutator chip architecture first, copper segment is not required to punching and row
Piece, makes that the technique of commutator is simple, and the cylindrical housings of copper segment are formed by copper coin method for coiling in addition, institute
High with circularity, commutator cylindrical is not required to reserve allowance, therefore reduces material consumption and cost；Meanwhile pass through circular cylindrical shell
The endoporus hole wall radial protrusion of body and the design of cavity, housing is set, with phenolic moulding powder strong bonded, while to use car in injection
Knife hook cuts out the strong bonded that housing and phenolic moulding powder are also greatly strengthened with hypotenuse annular groove come, and then makes the commutator of making
Structural strength is high, better conforms to high rotary speed working requirement.
Brief description of the drawings
The utility model has the following drawings：
Fig. 1 is the bottom direction view of roll type copper segment,
Fig. 2 is Fig. 1 A-A views.
Embodiment
As illustrated, roll type copper segment of the present utility model, there are cylindrical housings 1, cylindrical housings 1 it is upper
Portion has larger outside diameter, and the outer round surface of larger outside diameter is provided with the soldering bonding wire groove 5 processed with milling tool,
The endoporus hole wall of cylindrical housings 1 is laid with the radial protrusion 2 of 25 same shapes, adjacent radial in a circumferential direction
Cavity 3 is crossed between projection 2, the width of cavity 3 gradually broadens from the root of radial protrusion 2 toward top-direction, close to radially
Narrowed again to form necking 4 after quickly being broadened during the top of projection 2, described necking 4 is shaped as dove tail shape；In cylinder
In the short transverse of housing 1, the endoporus of cylindrical housings 1, which is provided with, cuts the upper annular groove 6 processed and lower annular groove 7 with lathe tool hook,
The upside cell wall and bottom land of upper and lower annular groove are rectangular, and downside cell wall and bottom land are in 45 degree of angles.
Claims (2)
1. roll type copper segment, it is characterised in that：With cylindrical housings, the top of cylindrical housings has compared with large cylindrical
Diameter, the outer round surface of larger outside diameter are provided with the soldering bonding wire groove processed with milling tool, cylindrical housings it is interior
Hole hole wall is laid with the radial protrusion of multiple same shapes in a circumferential direction, and cavity is crossed between adjacent radial projection, empty
The width of chamber gradually broadens from the root of radial protrusion toward top-direction, after quickly being broadened when close to the top of radial protrusion again
Narrow to form necking；In the short transverse of cylindrical housings, the endoporus of cylindrical housings, which is provided with to be cut with lathe tool hook, to be processed
The upper annular groove and lower annular groove come, the upside cell wall and bottom land of upper and lower annular groove are rectangular, and downside cell wall and bottom land are in angle.
2. roll type copper segment as claimed in claim 1, it is characterised in that：Described necking is shaped as dove-tail
Shape.
