Abstract

The invention discloses a method for making a motor shell. The method comprises the following steps: (1) processing a motor shell blank to required outer and inner diameter sizes according to design requirements; and (2) axially milling the outer surface of the motor shell to make a groove which is equally divided in circumference so as to form radiating fins. The motor shell which is made by the method of the invention has the advantages of good surface quality, excellent radiation performance, low cost and attractive appearance.

Description

A kind of manufacture method of motor housing
Technical field
The present invention relates to a kind of manufacture method of motor housing.
Background technology
Along with the development of motor process industry, the single-machine capacity of motor constantly increases, and economic and technical norms improve constantly.The growth of the unit volume loss that produces during the motor operation causes that motor each several part temperature raises, and life-span and operational reliability that this directly has influence on motor come into one's own day by day so motor heat is exchangeed problem.Particularly for the motor that relies on the cooling of casing appearance, the heat radiation situation of casing appearance will directly influence the temperature rise level of motor.
Studies show that, the heat dispersion of motor housing heat radiation wing, not only relevant, also relevant with its manufacturing process with its shape, surface texture.
At present, rely on the motor of casing appearance cooling, the manufacture method of casing heat radiation wing mainly is by casting and welds two kinds of methods shapings.For larger-size motor, there is critical defect in casting: the one, and, because size is bigger, casing belongs to thin-wall construction again, thereby is easy to generate casting flaw, and appearance is of poor quality, influences heat dispersion; In addition, casting also needs a large sum of die cost, the manufacturing cost height.And because the heat radiation wing is not tight with the casing applying during welding, there is air heat-insulation layer in the heat radiation wing made from welding between the two, and therefore, heat dispersion is not good enough yet.
Summary of the invention
In order to overcome the above-mentioned defective that prior art exists, the object of the present invention is to provide a kind of perfect heat-dissipating, surface quality is good, the manufacture method of the motor housing of low cost of manufacture.
The objective of the invention is to be achieved through the following technical solutions: it comprises the steps:
(1) by designing requirement, the motor housing blank is machined to required external diameter, internal diameter size;
(2) with the motor housing appearance vertically Milling Process go out the groove of circumference five equilibrium, form the heat radiation wing.
Described motor housing blank can be the hollow cylinder that forms of casting, or the hollow cylinder that is welded by steel plate.
The groove of described circumference five equilibrium is preferably the groove of axial perforation.
Technique effect of the present invention is: because heat radiation wing and motor housing are overall structures, and by the Milling Process moulding, also do not have air heat-insulation layer between heat radiation wing and the casing, therefore, surface quality is good, excellent radiation performance, manufacturing cost is lower, and appearance is also attractive in appearance.
Description of drawings
Fig. 1 is a motor housing blank shape schematic diagram;
The motor housing shape schematic diagram that Fig. 2 adopts the inventive method to make;
Fig. 3 is the right view of Fig. 2.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, Figure 1 shows that the motor housing blank 1 that processing is preceding.Figure 2 shows that the motor housing shape schematic diagram that adopts the inventive method to make.Its processing and manufacturing step is as follows:
(1) with motor housing blank 1 clamping on lathe, by designing requirement, be machined to required external diameter, internal diameter size;
Described motor housing blank 1 is for casting hollow cylinder that forms or the hollow cylinder that is welded by steel plate;
(2) motor housing 2 appearances that external diameter, internal diameter size adhered to specification Milling Process vertically go out the groove of the axial perforation of circumference five equilibrium, form heat radiation wing 3.
More than, just specifically describe preferred demonstration example of the present invention.Protection range of the present invention has more than and is limited to the above execution mode.All and technical scheme equivalence of the present invention all belongs to protection scope of the present invention.

Claims (4)
