It also comprises fixture, this fixture is: pull bar, connecting rod, joint pin, upper connecting base and piston ring connect to form axial moving device successively, the assembling of joint pin wherein, upper connecting base and piston ring on center shaft, joint pin is through central shaft, connecting rod and upper connecting base are linked together, base, transition seat, coil location seat connect to form clamp base successively, be assemblied on axial moving device, the inner end of central shaft is fixed on base, axial moving device can centrally be moved by axle, and the outer end of central shaft has two ring annular grooves at least; Floor installation is on transition disc;
Fixture also comprises coils protective hood, installing hole is established in the center of circle specifically at the bottom of cover, two that lead to installing hole, to hold spring passages are established along diametric(al) at the bottom of cover inside at the bottom of cover, each passage is tapered near a section of installing hole, making the bead in passage can expose passage but not drop out passage, is the screw of spring and holddown spring successively above bead; The installing hole of coils protective hood overlaps on a cannelure on center shaft; bead falls into cannelure location under the action of the spring; cover mouth is towards stator; to protect the coil on stator; the taper of coils protective hood mid portion; make the diameter of cover mouth be greater than diameter at the bottom of cover, cover mouth is identical with stator's external diameter.The effect of the taper formed is with guiding to the gland in propelling;
Said propulsive mechanism is, replace the top of propulsive mechanism with the push rod of the flanged dish in outer end, gland is connected on ring flange with mouth direction outwardly, and gland is identical with both motor casings internal diameter.
Processing is initial, first by stator sleeve on the piston ring of fixture, secondly coils protective hood is arranged on a cannelure of suitable central shaft, makes stator adjacent with coil protect cover, then motor casing is enclosed within coils protective hood; Machine tool hydraulic cylinder pulls pull bar to move, and whole axial moving device comprises piston ring and stator moves thereupon, and stator inner end leans against on positioning seat, and under the conical surface effect of central shaft, piston ring is by spreading simultaneously, and the frictional force between piston ring and stator increases, and stator is located.Propulsive mechanism is under the effect of its oil cylinder, and gland stretches out to motor casing, and under the guiding of protective sleeve, gland pushes motor casing to stator, realizes motor casing and stator elastic conjunction.After motor casing is in place, propulsive mechanism is return, and starts the processing of motor casing.After machining, pull bar resets, and piston ring unclamps, and the motor stator (live chassis) taking off protective cover He be processed into, carries out the replacing of workpiece.
Compared with prior art, good effect of the present invention is: on an equipment, complete the assembling of motor casing and stator and the processing of appointed part, improve production efficiency; Decrease the expenditure in firing equipment and place; Be provided with and have two ring annular grooves at least, may be used for the processing of different length motor casing (comprising stator).
Accompanying drawing explanation
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the fixture schematic diagram in Fig. 1.
Fig. 3 is the schematic diagram of the propulsive mechanism in Fig. 1.
Detailed description of the invention
See Fig. 1, it comprises the transition disc 4 on main shaft 100, pull bar 1 and propulsive mechanism 300, it also comprises fixture 200, see Fig. 2, this fixture is: pull bar 1, connecting rod 2, joint pin 9, upper connecting base 10 and piston ring 14 connect to form axial moving device successively, joint pin 9 wherein, upper connecting base 10 and piston ring are assemblied on central shaft 7, joint pin is through central shaft, connecting rod and upper connecting base are linked together, base 5, transition seat 8, coil location seat 11 connects to form clamp base successively, be assemblied on axial moving device, the inner end of central shaft is fixed on base, axial moving device can centrally be moved by axle, there are two ring annular grooves 23 outer end of central shaft, floor installation is on transition disc, 3 is screws, for cylinder lever connecting rod and connecting rod, 6 is linings, 12 and 13 is sealing rings,
Fixture also comprises coils protective hood 17, installing hole is established in the center of circle specifically at the bottom of cover, two that lead to installing hole, to hold spring passages are established along diametric(al) at the bottom of cover inside at the bottom of cover, each passage is tapered near a section of installing hole, making the bead 20 in passage can expose passage but not drop out passage, is the screw 18 of spring 19 and holddown spring successively above bead; The installing hole of coils protective hood overlaps on a cannelure 23 on center shaft, bead falls into cannelure location under the action of the spring, cover mouth is towards stator 15, to protect the coil on stator, coils protective hood mid portion taper 24, make the diameter of cover mouth be greater than diameter at the bottom of cover, cover mouth is identical with both stators 15 external diameter; The effect of the taper formed is with guiding to the gland in propelling;
