Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides inner and outer annular members that are pressure-bonded to each other and a method for manufacturing the same, in particular, it is possible to efficiently collect and form inner and outer annular members that are bonded to each other from a single material. The present invention relates to the ring-shaped moon and its manufacturing method.

An example of a device using this type of member is a rotary Tf machine shown in the attached drawings.

Specifically, in the figure, the symbol / is a frame plate, a is a stator clamper, and 3 is a welding part for attaching the stator laminated iron core to the frame plate 1 after it has been delivered to the stator clamper λ. Therefore, the inner diameter of the frame plate and the outer diameter of the stator clamp are machined to have the same dimensions, and the stator clamp fits into the rod with high precision. In addition, the code|symbol 5 is a stator.

As an example of the method of cutting out the frame plates/stator clamps, conventionally, as shown in Figures 1 and 5 of the accompanying drawings, each divided frame plate piece is cut from a separate plate. /a and the stator clamper dividing material 2a are cut out, and these are combined to form a hinoki as shown in Fig. iA and Fig. 7, and the connecting parts B and 7 are butt welded to form a single piece, and the frame plate material /' And stator clamper month! Therefore, in the past, in order to accurately fit the stator clamper λ to the frame plate/', the inner diameter of the frame plate material/' and the outer diameter of the stator clamper element/' It is safe to machine, and as a result, the inner diameter of the frame plate material/' which is the machined part, and the stator clamper material! Machining allowance is required for each outer diameter of the stator clamper. Therefore, the outer diameter of the stator clamper λ' is thicker than the inner diameter of the frame plate material /'.
That is, stake-clamper material from the inside of the frame board material/'! It was impossible to cut it out.

In this way, conventionally, the frame plate material /' and the stator clamper material λ' are each made by gas-cutting the divided portions from separate plates, then welding the divided portions together and bending them again. In addition, a frame plate material l' and a stake-clamper material a' were formed. As a result, the frame plate and stator clamper had extremely high material and processing costs, and also had low material usage efficiency.

The present invention eliminates the drawbacks in such conventional frame plate and stator clampers, that is, the inner and outer ring members that are joined to each other, and separates the inner ring from the inner member of the outer ring. Itadori 9 and by this,
The purpose of this invention is to provide an inner and outer ring part that increases the efficiency of recycling and reduces material and processing costs, and a method for manufacturing such seven-piece inner and outer ring parts.

In order to achieve this object, the present invention provides that at least a part of the joint on the inner and outer annular portion sides is formed by a slope, and the joint surface that is a part of the slope and the part overlapped by the slope have the same diameter. It is characterized in that any of the joint surfaces formed by forming the joint surfaces are joined to each other, and the position corresponding to the joint surface is determined from the manufacturing method or simple interest. a cutting step of cutting at an angle to form inner and outer annular member materials; a processing step of forming slopes on the inner and outer ring-shaped members formed by the cutting step into a desired joining shape; The 4 yen feature includes a joining step of joining the joining portions formed in the desired joining shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The member of the present invention and its manufacturing method will be described below with reference to the accompanying drawings showing a rotating electric machine as an example of the conventional member.

In FIG. 3, the symbol // indicates an outer ring-shaped member such as a frame plate;
12 is an inner ring-shaped RIS tcA, for example, a stator clamper, and /3 is a welding part for attaching the stator clamper /, 2 to the frame plate // after attaching the stator laminated iron core to the stator clamper /2.

In addition, the frame plate /l of the welding part /3 and the joint part /g of the stator crank burner are shaped, for example, as shown in the attached drawings 图7 to 77, and after they are accurately fitted and joined, It is fixed by welding part /3. In other words, Fig. 7 and Fig. 70 show a part of the slope as a joint surface, and Fig. 2 - Fig. 1S and Fig. 17 are constructed by forming the overlapping part of the slope with the same diameter. Figures 1 and 2 are examples of its application. Further, Fig. 1S shows an example in which a stopper /S is provided and a frame plate // is fixed to this by welding /6. In addition, the code|symbol 5 shows a stator.

The member of the present invention is constructed as described above, and a method for manufacturing the same will now be described with reference to the accompanying drawings 1g to 1m and 20.

First, from a single member, a frame plate material which will become the frame plate //, that is, an outer ring-shaped member material //', and a stator clamper 12
This is a cutting process in which the stator clamper material, that is, the inner annular member material /i, is cut out.This is a cutting process in which the position corresponding to the joint surface is set so that the cutting hole 2/ is cut out with respect to the perpendicular x of the single member. A certain angle θ, for example, 70~go'
In particular, the frame plate material / /' and the stator clamper material 72' are manufactured at the same time by circular gas cutting in a tilted state of 30 to 60 inches.
22 indicates a gap caused by cutting.

Next, this frame plate material / /' and stator clamper material /! Shape the sloped part of the required shape, e.g.
The joints are processed into a joint shape as shown in Fig. B+/7 to form a joint portion, and are used as a frame plate// and stator clumber material. This is the processing process.

The joint thus formed is joined after the necessary steps, such as, for example, attaching the stator head to the inner annular member or stator clamper 7.2. This is 7t;) at the beginning of the joining process.

The advantage of the present invention and its manufacturing method are constructed as described in -, but the joint portion is not limited to the above embodiment.

It may be oval or polygonal, and the joining surface is cut at an angle as shown in FIG. 25 in the same way as in the above embodiment, and a slope is formed and processed to form the above. A bonding surface as in the example may be formed.

Further, in the above embodiments, gas cutting is used for cutting, but the cutting method is not limited to this, and cutting methods such as machining, laser processing, and cutting may also be used.

As described above, since the member of the present invention and its manufacturing method are configured, the inner and outer annular members that are to be joined to each other can be simultaneously cut out from a single plate, and moreover, they can be joined with high accuracy. It can also be machined to obtain the required material, thus increasing the material yield and making it more efficient to use.In addition, the total manufacturing cost, including cutting costs and processing costs for joints and welding grooves, can be reduced. 1. It has the effect of being able to reduce costs.
