Son 12, makes the port of stator 12 vertically upward, and press 3 is correspondingly arranged at the top that stator clamps position 21.
Referring to shown in Fig. 2-5, warp beam is forwarded to move and is provided with a main shaft 41, the master on the suppressing action part 31 of the press 3
The center of rotation of axle 41 and the axis coinciding of the suppressing action part 31 of press 3, revolve on the main shaft 41 through transmission mechanism connection one
Rotary driving device 42, the drive shaft 41 of rotating driving device 42 is rotated, and the pressure head rotating mechanism 4 is constituted with this.
Referring to shown in Fig. 2-5, the just location-plate 61 is located under main shaft 41 with its plate face perpendicular to the axial direction of main shaft 41
Side（It is particularly located at the lower section of chuck）, just location-plate 61 is rectangular slab, and one side is used as the butt joint edge with feed mechanism, this pair
Rotor shaft embedded groove 611 is offered on edge fit, and just on location-plate 61 each convex downwards on two sides of butt joint edge
If one stops chimb 612, spacing is equal to the width dimensions of the electric motor end cap 14 on rotor 11 between two stop chimbs 612.Referring to
Shown in Fig. 2-5, spring connection is provided between the just location-plate 61 suppressing action part 31 of press 3 relatively, with this first location-plate
It is floating board status.
Shown in Figure 2, the feed mechanism 62 includes a pedestal 621, is set along straight feeding direction pair on the pedestal 621
One supporting plate 622 of setting should be slided at the butt joint edge of first location-plate 61, two supporting parts 6221 are extended in the front end of supporting plate 622,
This side-by-side parallel arrangement of two supporting part 6221, the width of the electric motor end cap 14 being smaller than on rotor 11 between two supporting parts 6221
Degree size.Effect has the first feeding driving device 623 on the supporting plate 622, and first feeding driving device 623 drives support
Plate 622 is moved, and two supporting parts 6221 is extended under just location-plate 61, and two supporting parts 6221 stop with the bottom surface of first location-plate 61 and two
Chimb 612 supplies to accommodate the space of the electric motor end cap on rotor around forming one.One is additionally provided with the supporting plate 622 and supplies rotor 11
On the gathering sill 6222 shelved of electric motor end cap 14, resistance of the gathering sill 6222 towards the end of first location-plate 61 and first location-plate 61
Space correspondence between gear chimb 612 is docked.In the gathering sill, the feeding pushing block 624 send one feeding pushing block 624 along level
Material direction is slidably connected with respect to supporting plate 622, and position is placed in the front of feeding pushing block 624 as rotor, there is effect on feeding pushing block 624
Second feeding driving device 625.
Above-mentioned press 3 preferably uses servo-pressing machine.
When motor pressing machine works, rotor 11 is first shelved on the rotor of feed mechanism 62 and is placed on position, will specifically turned
Electric motor end cap 14 on son 11 is hung on two supporting parts 6221, such as Fig. 2.Then, start shooting, the first feeding of feed mechanism 62 drives
Device 623 first drives supporting plate 622 to extend under just location-plate 61, and two supporting parts 6221 stop convex with the bottom surface of first location-plate 61 and two
Side 612 supplies the space for accommodating the electric motor end cap on rotor, then, driven by the second feeding driving device 625 and sent around forming one
Material pushing block 624 pushes just under location-plate 61 rotor 11 to, and now state is as shown in Figure 3 and Figure 4.Then, the top of ejector pin mechanism 52
Pin 521 is lifted under the driving of thimble drive device 522, and the top pressure of thimble 521 is acted on the rotating shaft lower end surface of rotor 11, and thimble
521 will push up on rotor 11, just be lifted in the compression spring of location-plate 61, and the rotating shaft upper end of rotor 11 is to stretch into chuck, is pressed from both sides by chuck 51
Firmly, reliable again accurately to position rotor 11, now feed mechanism 62 is overall returns, such as Fig. 5 states.Followed by press 3 is opened
Dynamic, the lower laminate part 31 of press 3 is pushed, while thimble 512 is moved down therewith, is pressed in stator 12 rotor 11 with this, under
During pressure when the pressure sensor in control circuit reflects reaches certain pressure value, that is, represent in gear 13 and stator 13
Gear collide and cannot engage, now, just control rotating driving device 42 rotate, main shaft 41 is revolved with rotor 11 through chuck
Turn, once pressure sensor reflects that pressure value declines i.e. control rotating driving device 42 and is stopped, the gear 13 of rotor 11
Both the gear successfully with stator 12 was meshed, and then pushed when pushing actuating member 31 and reach displacement press i.e. stopping, completing
Assembling.
In said process, the operating principle of chuck 51 is：When the roller end of rotor 11 is stretched into chuck 51, axial direction is withstood on
Compress on face 5123, will be pushed up on fixture block 512, due to being slidably matched for taper acting surface 5112 and taper fit face 5121, fixture block
512 are clamped the rotating shaft shaft end of rotor 11 with its radial effect face 5122, then, when the overcoat 511 of the banding chuck 51 of main shaft 41
During rotation, friction makes steel ball 513 coordinate with effect inclined-plane 5124, each fixture block 512 is held more the rotating shaft shaft end of rotor 11
Tightly, revolving force reliably can be passed into rotor 11, and when clamping, the upper end end face of rotor shaft is by the location division of taper
The contact of 411 top pressures, also ensure that the accuracy of its positioning.And when axial pressure on top surface is eliminated, each fixture block is in elastic unit
Resetted under part elastic force, chuck smoothly unclamps.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this that it is not intended to limit the scope of the present invention.It is all according to the present invention
