Position part, further includes pressure head ball.
The center of the upper surface of the pressure head part offers a hemispheric pressure head ball blind hole.
The pressure head ball is hemisphere, and pressure head ball spherical surface mobilizable setting directed downwardly is in the pressure head ball blind hole
In；The upper surface of the pressure head ball is higher than the upper surface of the pressure head part.
The press locating part is socketed in the top of the pressure head part；The press locating part and stator press-loading machine connect
It connects, the upper surface of the press locating part is vertical with the central axes of stator press-loading machine.
Further, the pressure head locating part includes limitting casing and positive stop strip；The opening down setting of limitting casing；Two
The positive stop strip is connect with the lower edge of the limitting casing；Two positive stop strips are symmetrical arranged；The pressure head part is connected across institute
It states on positive stop strip.
Further, the material of the pressure head ball is steel.
A kind of stator press-loading Special pressing head of the invention, i.e., increase pressure head ball on pressure head part, is carrying out press fitting work
When sequence, the pressure of press acts on pressure head ball, and pressure head part is evenly transferred to centered on pressure head ball, pressure head and workpiece stress
It is evenly distributed, avoids generating microdisplacement, ensure that press fitting quality, improve the technological level of stator press-loading.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of stator press-loading Special pressing head of the invention in the free adjusting stage；
Fig. 2 is a kind of schematic diagram of the ideal stator press-loading state of stator press-loading Special pressing head of the invention；
Fig. 3 is a kind of schematic diagram of the press fitting state of stator press-loading Special pressing head of the invention when stator is slightly slanted.
Specific embodiment
In order to preferably understand technical solution of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail:
Referring to Fig. 1, a kind of stator press-loading Special pressing head, including pressure head part 1 and pressure head locating part 2, it further include pressure head
Ball 3.The material of pressure head ball 3 is steel.
The center of the upper surface of pressure head part 1 offers a hemispheric pressure head ball blind hole.
Pressure head ball 3 is hemisphere, and the mobilizable setting directed downwardly of 3 spherical surface of pressure head ball is in pressure head ball blind hole；Pressure head ball 3
Upper surface is higher than the upper surface of pressure head part 1.
Press locating part 2 is socketed in the top of pressure head part 1.Pressure head locating part 2 includes limitting casing 21 and positive stop strip 22；Limit
The position opening down setting of frame 21；Two positive stop strips 22 are connect with the lower edge of limitting casing 21；Two positive stop strips 22 are symmetrical arranged.
Pressure head part 1 is connected across on positive stop strip 22.Press locating part 2 is connect with stator press-loading machine, the upper surface of press locating part 2 and fixed
The press gas spring axis 6 of sub- pressing machine is vertical.
Before being pressed, pressure head part 1 is in free state.4 face casing 5 of stator core, the dedicated pressure of stator press-loading
Head is arranged above stator core 4.For pressure head when the end face with stator core 4 contacts, the operative end surface of pressure head part 1 is i.e. with fixed
Subject to the end face of the iron core 4 of son, in the range of pressure head locating part 2, make and the perpendicular level of stator press gas spring axis 6
The displacement and rotation in face direction.After pressure head part 1 completes the adjustment of 4 freedom degrees, the pressure of pressure head part 1 and stator core 4
Dress surface is bonded to each other.Since the end face of each stator core is all not quite similar, so requiring to carry out certainly every time before press fitting
By adjusting.
Referring to FIG. 2, in an ideal case, after stator press-loading machine starts press fitting, press is persistently pushed, until pressure head part
1 pressure head ball 3 is under pressure.Pressure is acted on the middle position of pressure head part 1 by pressure head ball 3, and by pressure conduction to pressure head
The middle position of part 3 and 4 contact surface of stator core.Centered on pressure head ball 3, the stress of pressure head part 3 and stator core 4 is flat
It is distributed.Microdisplacement can be generated during being pressed into casing 5 to avoid stator core 4 in this way, to avoid to casing 5
Structure and intensity impact.
Then, press continues to press to the position (pressure control position) of requirement, to complete entire stator press-loading process.
Referring to FIG. 3, if there is the inclination of certain angle in the end face of stator core 4, will lead to pressure head in press fitting process
Part 1 is tilted in the free adjusting stage.If press is directly pressed at this time, the related stator iron of pressure head part 1 can be made
The discontinuity of core 4 deviates to make to be pressed into track, in this way can structure to casing 5 and intensity cause adverse effect.
A kind of stator press-loading Special pressing head of the invention, when facing such situation, the upper surface of pressure head ball 3 keeps horizontal, pressure head
The spherical surface and pressure head part 1 of ball 3 produce relative rotation, and when press pushes and applies pressure to pressure head ball 3, pressure head ball 3 can will be made
It is firmly average to be applied to pressure head part 1 and stator core 4, it has modified and is pressed into track, incline to reduce 4 end face of stator core
The tiltedly adverse effect caused by press fitting process, ensure that the quality of stator press-loading.
Present invention emphasis science, courageously design, terminal with compact integral structure is easy, put into small effect greatly, operation is simple, safety.
The present invention is in the small machine industry only authentic brand.Technological effect has world lead level.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
