In the present invention, described the second catch bar 336, described the first catch bar 333, described spring structure 332 and described connecting rod 331 form link gear successively.
The use procedure of the assembling device of described rotor and stator is as shown in Figure 16 A-Figure 16 D:
The first step, the original state of the assembling device of rotor and stator as described in as shown in Figure 16 A being, described the first catch bar 333 contacts with described the second catch bar 336, now, be arranged on described spring structure 332 between described the first catch bar 333 and described connecting rod 331 in natural stretched condition, described connecting rod 331 is all in described the first joint sleeve 3251. Before starting described driving mechanism 315 and described power source 339, successively described the second end cap 302, described stator 100 are seated in the second putting groove 322 of described the second assembling element 32. Simultaneously successively by described the first end cap 301, described rotor 200 be seated in the first putting groove 312 of described the first assembling element 31 and utilizes fixture to be fixed, and adjusts the position of described stator 100 and described rotor 200, and both are oppositely arranged.
Second step, as shown in Figure 16 B, starts described drives structure 315 and described power source 339, and described driving mechanism 315 promotes described the first assembling workpiece 31 and moves along diagram arrow m direction; Described power source 339 injects air through described air admission hole 337 in described airtight cavity (not label), air pressure in described airtight cavity is increased, described motion stops 3362 is subject to being pushed after larger air pressure, and driving connected described the second catch bar 336 to move along the inwall of described the second joint sleeve 334, described the second catch bar 336 promotes described the first catch bar 333 and moves along arrow n direction; Described spring structure 332 is subject to after the active force from the second catch bar 333, there is deformation and can transmit cushioning effect power to described connecting rod 331, after described connecting rod 331 is pushed, steadily move along n direction, and progressively extend out to the height 5-20cm higher than described stator 100 by described the second through hole 321. Now, described spring structure 332 is in compressive state.
Wherein, arrow m direction and arrow n direction are parallel to each other, and described connecting rod 331 can determine according to described stator 100 and the size of described rotor 200 higher than the height of described stator 100.
The 3rd step, refers to Figure 16 C, and when described connecting rod 331 rises to precalculated position, described power source 339 continues running, makes described connecting rod 331 remain on described precalculated position a period of time; Described the first assembling workpiece 31 continues to drive described rotor 200 to move, described rotating shaft 201 is held in the internal cavities of described connecting rod 331, and with the inwall laminating of described connecting rod 331, because the external diameter size of the described rotating shaft 201 of described rotor 200 matches with the internal diameter size of described connecting rod 331. The described spring structure 332 being connected with described connecting rod 331 is subject to the active force from described rotating shaft 201, produces certain deformation.
Meanwhile, described fixed bar 323 is through described fixing hole 314, along with described rotating shaft 201 is progressively held in described connecting rod 331, described fixed bar 323 progressively stretches out described fixing hole 314, after the first platform 316 of described the first assembling element 31 contacts with described height piece 324, between described the first assembling element 31 and described the second assembling element 32, be restricted and stop mutually near motion.
The 4th step, after described rotating shaft 201 completes with described connecting rod 331 clampings, described power source 339 reduces gas supply gradually, described the second catch bar 336 homing gradually, also homing gradually of described the first catch bar 333, because described the first catch bar 333 is connected with described spring structure 332, described spring structure 332 loses the support force from the first catch bar 333, described spring structure 332 bottoms are replied original form gradually, its form is replied the top that is expanded to gradually described spring structure 332 by bottom, described spring structure 332 drives described connecting rod 331 to reply original position. now, described driving mechanism 315 is converted at a slow speed and moves, and drives described rotor 200 to move towards described stator 100 directions. owing to having by described rotating shaft 201 and described connecting rod 331 conduct guidings, the assembling of described rotor 200 and described stator 100 there will not be the problem of axle offset, and can make described rotor 200 and described stator 100 is coaxial assembling.
Wherein, described rotating shaft 201 is down moved for synchronizeing with described connecting rod 331.
The 5th step, as shown in Figure 16 D, when the gas in described airtight cavity completes eliminating, described motion stops 3362, described the second catch bar 336, described the first catch bar 333, described spring structure 332 and progressively homing of described connecting rod 331. When described rotating shaft 201 is driven and entered after described the second through hole 321 by described connecting rod 331, between described the first end cap 301 and described the second end cap 302, cooperatively interact fixing, because described rotor 200 is fixing with described the first end cap 301, described stator 100 is fixing with described the second end cap 302, therefore, in the time that described connecting rod 331 continues to move towards original position, because described rotor 200 has been fixed, therefore, described connecting rod 331 separates gradually with described rotating shaft 201.
The 6th step, when described connecting rod 331 separates completely with described rotating shaft 201, closes the fixture of described the first assembling workpiece 31, and the first platform 316 is separated with described the first end cap 301. Separate described the first assembling workpiece 31 and described the second assembling workpiece 32, described stator 100 and the described rotor 200 that assembling can be completed take out, and complete once the assembling of described rotor 200 and described stator 100.
The present invention some preferably in embodiment, described connecting rod 331 can stretch out described the second platform 326 through described the second through hole 321, the length of described connecting rod 331 is at least greater than the height of described stator 100, at some, preferably in embodiment, the height of described connecting rod 331 is greater than the about 1-15cm of height of described height piece 324.
Refer to Figure 17, described thrust unit 33 further comprises a thin slice 325, described thin slice 335 is arranged on the middle part of described promotion workpiece 33, described the second catch bar 336 arranges through described thin slice 335, described thin slice 335 can be used for the second joint sleeve 334 of described promotion workpiece 33 to be fixed, it can not moved with respect to described the first joint sleeve 3251, thereby avoid affecting the motion of described the second catch bar 336.
From Figure 17, it can also be seen that, described the second catch bar 336 is coniform with one end that described the first catch bar 333 is connected, and it can be beneficial in the time that described the second catch bar 336 promotes described the first catch bar 333, makes force localization, thereby improves the efficiency promoting.
Refer to Figure 18, it is for assembling described rotor 200 and described stator 100 also mode between described the first end cap 301 and described the second end cap 302, between described rotor 200 and described stator 100, form an air gap d, adopt after the assembling device 30 of described rotor provided by the present invention and stator, described air gap d can be and is less than 0.75mm, more preferably described air gap d can be 0.4-0.7mm, and described rotor 200 is coaxial setting with described stator 100, its air gap distance homogeneous.
