Abstract
The utility model discloses an automobile starting motor shell. The shell is a cylinder with a weld joint (F), wherein the cylinder is made through rolling a hot-rolled steel plate. Several radial holes (A) which are circumferentially and uniformly distributed are punched on the cylinder. An outboard end of each radial hole (A) is provided with a chamfer. A left positioning round bench (B) is milled on an outer circumference of a left end of the cylinder. A left positioning gap (C) is punched on the left positioning round bench (B). A right positioning round bench (D) is milled on the outer circumference of a right end of the cylinder. And a right positioning gap (E) is punched on the right positioning round bench (D). Compared to a traditional starting motor shell which is made through machining a seamless steel tube, by using the starting motor shell of the utility model, there are the advantages that processing is convenient; manufacturing cost is low; consistency is good; a service life is long and so on.
Description
Technical field
The utility model relates to the shell that a kind of car starter motor is used, and belongs to field of mechanical technique.
Background technology
Starting motor of automobile is excitation electromotor, is the important spare part of automobile engine, and the starter motor shell is the major part that guarantees the excitation electromotor performance.
The starter motor shell is cylindrical shape, and traditional starter motor shell all adopts seamless steel pipe to make through machining, and the subject matter of existence is:
(1) the technology process equipment that relates in the traditional machine side of adding is various, and technology is loaded down with trivial details, causes that working (machining) efficiency is low, manufacturing cost is high, expensive;
(2) the phosphorus content height (phosphorus content is up to 20%) of existing seamless steel pipe, the phosphorus content height can cause the motor magnetic loss serious, and starting efficiency reduces gradually, until inefficacy;
(3) the conventional machining process precision is low, consistency is poor, the percent defective height.
The utility model content
The utility model aims to provide the starter motor shell of a kind of easy to process, low cost of manufacture, high conformity, long service life.
For solving above technical problem, a kind of automobile-used starter motor shell that the utility model provides, be to roll the cylinder that has weld seam (F) that forms by hot rolled steel plate, in described cylinder upper punch some circumferentially uniform radial holes (A) are arranged, and the outboard end of each radial hole (A) is provided with chamfering, the excircle of described cylinder left part is provided with left positioning round table (B), and in this left side positioning round table (B) upper punch left locating notch (C) is arranged, the excircle of described cylinder right part is provided with right positioning round table (D), and in this right side positioning round table (D) upper punch right locating notch (E) is arranged.
This starter motor shell adopts hot rolled steel plate to roll behind the cylinder of back again, and weld seam forms, four radial holes are respectively the magnet steel hole, left side positioning round table is combined with left locating notch, right positioning round table is combined with right locating notch, one group is the coarse positioning structure during towards radial hole, the fine positioning structure of another group for towards radial hole the time.
Be preferably, the external diameter φ 1 of the left positioning round table in a described left side (B) is unequal with the external diameter φ 2 of right positioning round table (D), the width H2 of the width H1 of described left locating notch (C) and right locating notch (E) is unequal, and left locating notch (C) forms an angle with right locating notch (E); Left positioning round table and right positioning round table, left locating notch and the difference of right locating notch are arranged, can effectively avoid in the course of processing, when being installed to shell on the punching die, adorn anti-situation.
The beneficial effects of the utility model are:
(1) adopt high-quality hot rolled plate rather than traditional seamless steel pipe, the phosphorus content of high-quality hot rolled plate low (about 7%) effectively reduces magnetic loss, has improved electric efficiency, has reduced motor remanent magnetism coefficient widely, has prolonged the useful life of motor;
(2) adopt hot rolled plate directly to roll welding, technology is simple, equipment is single, production efficiency is very high, and hot rolled plate is cheap simultaneously, has realized processing and raw-material low cost;
(3) weld seam forms to adopt hot rolled steel plate to roll behind the cylinder of back again, and the shell precision is very high, and product size is stable, high conformity, out of roundness is brought up to 0.05mm by original 0.4mm, has further reduced magnetic loss, improves electric efficiency and reduces the thermal loss that temperature rise brings.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
In conjunction with Fig. 1---automobile-used starter motor shell shown in Figure 4 is to roll the cylinder that has weld seam F that forms by hot rolled steel plate, have four circumferential uniform radial hole A to be used for magnet steel is installed in the cylinder upper punch, and the outboard end of each radial hole A is provided with chamfering.The excircle of cylinder left part is provided with left positioning round table B, and in this left side positioning round table B upper punch left locating notch C is arranged.The excircle of cylinder right part is provided with right positioning round table D, and in this right side positioning round table D upper punch right locating notch E is arranged.The quantity of radial hole A is not limited to four, arranges as required.Left side positioning round table B and right positioning round table D adopt Vehicle Processing to form.
Preferably, the external diameter φ 1 of left positioning round table B is unequal with the external diameter φ 2 of right positioning round table D, the width H1 of left side locating notch C and the width H2 of right locating notch E are unequal, and left locating notch C and right locating notch E form an angle, and this angle is α 1+ α 2 sums.The material of hot rolled steel plate is preferably Q195, also can select for use other phosphorus content to be lower than 7% high-quality hot rolled steel plate.
