Abstract
The invention relates to a special expansion table for machining of an inner stepped hole of a stator and a machining method of the special expansion table. The special expansion table comprises a table base and a plug pin. The special expansion table is characterized in that the table base is a big-end-down conical barrel, the upper portion and the lower portion of the table base are evenly provided with multiple straight slits which intersect with one another, the plug pin is a conical table, the small end of the plug pin faces downwards, and the outer diameter of the small end of the plug pin is slightly smaller than the inner diameter of the small end of the table base. The upper portion of the table base is evenly provided with three straight slits, and the lower portion of the table base is also evenly provided with three straight slits. The depth of the upper straight slits of the table base is up to 80% of the height of the table base. The machining method comprises two steps, namely fixing and rotary machining. Due to the design of the special expansion table, the expansion table is placed into the stator, and then the plug pin is inserted in the expansion table, so that the outer diameter of the expansion table is increased, and then the stator is fixed; next, the expansion table is rotated to drive the stator to rotate so that the stepped hole can be machined conveniently. The special expansion table is simple in structure, convenient to use and practical; damage to the outer surface of the stator by a fixture is avoided, the clamping stability of the stator is guaranteed, and cases are reliable.
Description
Technical field
The present invention relates to electric equipment spare and accessory parts manufacture field, specifically rise platform and processing method thereof of stator inner bore of step processing special use.
Background technology
Motor (English: Electric machinery, be commonly called as " motor ") refer to according to the law of electromagnetic induction and realize a kind of calutron that electric energy is changed or transmitted, in circuit with the old standard D of alphabetical M() represent, its Main Function is to produce driving torque, as the power source of electrical appliance or various machineries.Generator represents with alphabetical G in circuit, and its Main Function is to utilize mechanical energy to be converted into electric energy, at present the most frequently used, utilizes the pushing generator rotors such as heat energy, water energy to generate electricity.
Motor is generally comprised of stator, rotor, bearing, casing, end cap etc.Stator is the actionless part of motor.Stator is comprised of stator core, stator winding and support three parts.The Main Function of stator is to produce rotating magnetic field, and the Main Function of rotor is by magnetic force line cutting and then generation (output) electric current in rotating magnetic field.Stator is comprised of iron core, coil, skeleton (what have does not have), lead-in wire, extension spring etc. conventionally.Stator has two kinds of modes of connection, and a kind of is 4 line formulas, and rotor series winding is connected between 2 stator winding, and a kind of is 2 line formulas, connects (2 lead-in wires at 4 line formula diagonal angles are connected together) after 2 stator winding connect with rotor series winding after connecting with rotor series winding again again.Two kinds of mode of connection differences, but can be general.Lead wire mode has two kinds: a kind of is that flexible cord is drawn; A kind of is to draw by the plug connector on skeleton, during this kind of coiling, will retain skeleton.Convenient for the coiling of stator winding, some can be arranged to stator inner hole stepped, for stepped endoporus, also there is no a kind of size stator inner bore of step processing method accurate, simple to operate, easy to process at present.
Summary of the invention
The present invention is directed to above technical problem, provide a kind of size stator inner bore of step processing method accurate, simple to operate, easy to process, also provide stator inner bore of step to process the required stator of the special-purpose fixed stator platform that rises simultaneously.
The present invention is achieved through the following technical solutions.
The stator inner bore of step processing special use platform that rises, comprises pedestal, latch, it is characterized in that pedestal is up-small and down-big conically shaped, pedestal top, bottom are evenly provided with a plurality of vertical masonry joints that cross one another, latch is taper platform, and compared with small end down, it is slightly less than pedestal compared with small end internal diameter compared with small end external diameter to latch.Pedestal top is evenly provided with three vertical masonry joints, and pedestal bottom is evenly provided with three vertical masonry joints.On pedestal, vertical masonry joint depth reaches 80% of pedestal height.
Stator inner bore of step processing method, comprises following two steps:
One, fixing
Stator to be processed is placed on the pedestal of the platform that rises, then latch is inserted to the platform that rises has in pedestal, compress latch, stator can be securely fixed in and rise on platform;
Two, rotation processing
The platform that will rise is fixed on process equipment, and rotary expansion platform, puts down cutter, can realize synchronous processing to many planes appointed part such as the endoporus of stator, inner bore of step.
The present invention, owing to having designed the special-purpose platform that rises, puts into stator interior by the platform that will rise, and then inserts latch, and the platform external diameter that makes to rise expands, thereby then fixed stator is rotated by the platform that will rise, and drives stator rotation, to facilitate, processes shoulder hole.
The present invention is simple in structure, convenient and practical, has avoided the damage of fixture to stator outer surface, has guaranteed again the stability to stator clamping, and case is reliable.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the structural representation of the platform that rises of the present invention, wherein:
1-pedestal, 2-latch.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The stator inner bore of step processing special use platform that rises, comprise pedestal 1, latch 2, it is characterized in that pedestal 1 is for up-small and down-big conically shaped, pedestal 1 top, bottom are evenly provided with a plurality of vertical masonry joints that cross one another, latch 2 is taper platform, compared with small end down, it is slightly less than pedestal 1 compared with small end internal diameter compared with small end external diameter to latch 2.Pedestal 1 top is evenly provided with three vertical masonry joints, and pedestal 1 bottom is evenly provided with three vertical masonry joints.On pedestal 1, vertical masonry joint depth reaches 80% of pedestal 1 height.
Stator inner bore of step processing method, comprises following two steps:
One, fixing
Stator to be processed is placed on the pedestal 1 of the platform that rises, then latch 2 is inserted to the platform that rises has in pedestal 1, compress latch 2, stator can be securely fixed in and rise on platform;
Two, rotation processing
The platform that will rise is fixed on process equipment, and rotary expansion platform, puts down cutter, can realize synchronous processing to many planes appointed part such as the endoporus of stator, inner bore of step.
The present invention, owing to having designed the special-purpose platform that rises, puts into stator interior by the platform that will rise, and then inserts latch 2, and the platform external diameter that makes to rise expands, thereby then fixed stator is rotated by the platform that will rise, and drives stator rotation, to facilitate, processes shoulder hole.
The present invention is simple in structure, convenient and practical, has avoided the damage of fixture to stator outer surface, has guaranteed again the stability to stator clamping, and case is reliable.
