Abstract
The utility model provides an automobile oil pump motor connects end cover. Its structure is a whole, adopts the whole processing of digit control machine tool to form, and the round platform form of its shape for having the step is including base portion and round platform portion, its base portion is circular to it is provided with a plurality of screw hole to circle the symmetry at circumference no. 1, round platform portion be interior empty structure, internally mounted has brush and positioner, the diameter of round platform portion is greater than the third of base portion diameter. The utility model discloses simple structure, processing is convenient, and the assembly is easy, has improved the precision of motor end cover to the easy change.
Description
Technical field
The utility model relates to motor device technical field, is specifically related to a kind of automobile fuel pump motor and connects end cap.
Background technology
The type of end cap has many kinds, and Main Function is the locus of the axle determining rotor, needs and multi-form bearing fit, is connected on the shell of fixed electrical machinery stator by end cap, ensure the gap of rotor and stator.
End cap is bad, directly has influence on the quality of electric motor, and therefore, a good end cap, mainly from its cardiac electric brushing piece, its effect is the rotation of rotor driven, and this part is the part of most critical.As long as because brush plate has a link to go on business, the quality of electric motor all can be affected.Brush is too high, can encounter piezo-resistance; The packing ring of white is encountered in too low meeting; (seeing rotor) is too short, and it touches less than rotor.Rotor can be made like this to operate; Brush bifurcated, can make electric current unstable; Certainly more can not bend, it can make electric current abnormal.
The processing of end cap generally adopts casting technique, end cap is divided into base and lid separate machined, after casting, and then installs, and because the precision comparison of cast member itself is low, therefore there is following problems:
End cap adopts two-stage to install, and be not easy location, precision is not high enough, easily occurs the phenomenon that oil pump is stuck and delayed.
Summary of the invention
The purpose of this utility model is for above-mentioned Problems existing, and provide a kind of structure simple, easy to process, assembling easily, improves the precision of electric motor end cap, and holds easily changeable automobile fuel pump motor connection end cap.
The purpose of this utility model realizes being made up of following aspect:
A kind of automobile fuel pump motor connects end cap, and its structure is as a whole, adopts Digit Control Machine Tool overall processing to form, it is characterized in that: its shape is round table-like with step, includes base portion and round platform portion; Its base portion is circular, and is symmetrically arranged with several screwed holes on circumference one encloses; Described round platform portion is hollow structure, and inside is provided with brush and positioner, and the diameter in round platform portion is greater than 1/3rd of base portion diameter.
In such scheme, the upper surface of described base portion is also provided with the groove of ring-type, staggers in the position of groove and screwed hole, for reducing the weight of end cap.
In such scheme, the lower surface of described base portion is plane, is also provided with the ring-shaped groove for weight reduction in lower surface.
Principle of the present utility model is that end cap is set to overall structure, and is provided with multiple groove for weight reduction, adds the precision of end cap.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to process, and assembling easily, improves the precision of electric motor end cap, and easily changes.
Accompanying drawing explanation
Fig. 1 is traditional end cover structure figure;
Fig. 2 is the utility model example structure figure;
1 base portion in figure, 2 round platform portions, 3 screwed holes, groove on 4,5 lower groove.
Embodiment
For better understanding skill Design Technology of the present utility model, be described below in conjunction with drawings and Examples.Following examples describe and are only exemplary and explanatory, do not have any restriction to the utility model protection range.
Automobile fuel pump motor as shown in Figure 1 connects end cap, and its structure is as a whole, adopts Digit Control Machine Tool overall processing to form, and its shape is round table-like with step, includes base portion 1 and round platform portion 2; Its base portion is circular, and is symmetrically arranged with several screwed holes 3 on circumference one encloses; Described round platform portion 2 is hollow structure, and inside is provided with brush and positioner, and the diameter in round platform portion 2 is greater than 1/3rd of base portion 1 diameter.
In the present embodiment, the upper surface of described base portion 1 is also provided with the upper groove 4 of ring-type, and upper groove 4 staggers, for reducing the weight of end cap with the position of screwed hole 3.
In the present embodiment, the lower surface of described base portion 1 is plane, is also provided with the annular lower groove 5 for weight reduction in lower surface.
Protection range of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various change and distortion to the utility model and not depart from scope and spirit of the present utility model.If these are changed and distortion belongs in the scope of the utility model claim and equivalent technologies thereof, then intention of the present utility model also comprises these changes and distortion.
