Abstract

The invention relates to a vehicle generator brush end cover and a manufacture method thereof. The vehicle generator brush end cover comprises a end cover body, a shaft hole, a plurality of radiation holes, and a corner approach 5, wherein the tail end of the corner approach is provided with a boss and a corner approach hole, the radiation holes are arc, counter bores are arranged in the radiation holes, and the boss is oval or long circle. The manufacture method has the following steps of casting a blank of a bush end cover; designing the positions of a regulator and a rectifier bridge; drilling out the counter bores; calculating the center distance between the corner approach hole and the shaft hole; and drilling out the corner approach hole. The vehicle generator brush end cover has the advantages that 1. the positions of the counter bore and the corner approach hole can be determined by the convex position of a generator and the specific position of a vehicle generator in a vehicle, so that the manufacture cost is greatly lowered, and the entire manufacture procedures are simpler; 2. the diameter of the radiation hole is less than that of the counter bore, so that the counter bore can be arranged above the radiation hole; and therefore, the radiation hole area is enlarged, the radiation performance of the generator is improved, and the weight of the vehicle generator is lowered.

Description

Alternator for vehicle brush cover and manufacture method thereof

Technical field

The present invention relates to a kind of alternator for vehicle brush cover and manufacture method thereof.

Background technology

Alternator for vehicle is comprised of belt pulley, Driving terminal assembly, rotor assembly, field frame assembly, adjuster, rectifier bridge, back cover and brush cover.On brush cover, be provided with axis hole, louvre and for the screwed hole of rectifier bridge, adjuster is installed, in a side of brush cover, be provided with and hang ，Gua angle, angle end and be provided with round boss, at boss center, be provided with Gua Jiao hole.Because the shape difference of the engine of each manufacturer production is very large, for making projection, the leading-out terminal of generator, non-interference between the leading-out terminal of adjuster on engine, the ,Gua Jiao hole, position of screwed hole and the centre-to-centre spacing of axis hole on the alternator for vehicle using from different engine collocation will be determined the concrete installation site in car body according to the protruding position on engine and alternator for vehicle.Therefore, the casting mould used with the brush cover of the alternator for vehicle of different engines collocation use is also different.And design, make mold process loaded down with trivial details, waste time and energy, cost is high, increased the difficulty of processing of alternator for vehicle brush cover, increased processing cost.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of applied widely, difficulty of processing is little, processing cost is low alternator for vehicle brush cover and manufacture method thereof.

The present invention is achieved in that

A kind of alternator for vehicle brush cover, comprise end cap body, on end cap body, be provided with axis hole and louvre 3, a side at end cap body is provided with extension angle 5, and at extension angle, end is provided with boss 6, is provided with Gua Jiao hole on boss, its special character is: described louvre is a plurality of and is arc, on louvre, be positioned at end cap body inner side and be provided with counterbore 4, the diameter of described louvre is less than the diameter of described counterbore, and described boss is ellipse or Long Circle.

Described louvre is arranged and is formed multiple row concentric ring, to guarantee making heat-sinking capability reach maximum in limited space.

A manufacture method for alternator for vehicle brush cover, its special character is that concrete steps are as follows:

1) utilize die casting to go out brush cover blank;

2) measure the protruding position of the engine using with this generator collocation, the position of design adjuster, rectifier bridge, makes projection on engine, the leading-out terminal of generator, non-interference between the leading-out terminal of adjuster;

3), according to the position of adjuster, rectifier bridge, on louvre, be positioned at end cap body inner side and get out counterbore;

4) installation site in automobile according to electric generators for automobile, the centre-to-centre spacing of calculating Gua Jiao hole and axis hole;

5) according to calculate Gua Jiao hole and the centre-to-centre spacing of axis hole on boss, get out Gua Jiao hole.

The invention has the beneficial effects as follows:

1, owing to being provided with the louvre of arc on die ontology, and boss be shaped as Long Circle or ellipse, the position in counterbore and Gua Jiao hole can be determined by the particular location in car body according to the protruding position of engine and alternator for vehicle, therefore, do not need to change the brush cover that mould can process the generator that can be used in conjunction with from different engines, compare from the method that adopts different moulds to make brush cover for different engines, greatly reduce production cost, and whole manufacturing procedure is simpler.

2, due to the diameter of louvre, be less than the diameter of counterbore, so counterbore can be located at louvre top, increased the area of louvre, improved the heat-sinking capability of generator, and reduced the weight of alternator for vehicle.
