Summary of the invention
For solving the problems of the technologies described above; the object of this invention is to provide a kind of jig of belt coil defencive function; the present invention and stator are installed successively on lathe transition disc; stator is positioned; lathe propulsive mechanism is to stator direction pushing motor shell; motor stator is pressed in motor casing, realizes the cold-pressing assembly of motor casing and stator, after having assembled, carry out machining.
The object of the present invention is achieved like this: it comprises pull bar, it is characterized in that: pull bar, connecting rod, joint pin, upper connecting base and piston ring connect to form axial moving device successively, joint pin wherein, upper connecting base and piston ring are assemblied on central shaft, joint pin is through central shaft, connecting rod and upper connecting base are linked together, transition disc, base, transition seat, coil location seat 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 be moved along central shaft, the outer end of central shaft has two ring annular grooves at least, transition disc is arranged on main shaft,
It also comprises coils protective hood, specifically establish installing hole in the center of circle at the cover end, establish two in inner side, the cover end along cover end diametric(al) and lead to passage installing hole, that hold spring, 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 is enclosed within on a cannelure on central shaft; bead falls into cannelure location in the effect of spring; cover mouth is towards stator; with the coil on protection stator; the taper of coils protective hood mid portion; make the diameter of cover mouth be greater than the diameter that covers the end, cover mouth is identical with the two external diameter of stator.The effect of the taper forming is with guiding to the gland in advancing;
Said lathe propulsive mechanism is, replaces the top of propulsive mechanism with the push rod of the flanged dish in outer end, and gland is connected on ring flange with mouth direction outwardly, and gland internal diameter is slightly less than motor casing 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, make stator adjacent with coil protect cover, then motor casing be enclosed within on coils protective hood; Machine tool hydraulic cylinder pulls pull bar to move, and whole axial moving device comprises that piston ring and stator move 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 makes stator location.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 is pushed motor casing to stator, realizes motor casing and stator interference assembling.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) that takes off protective cover and 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, improved production efficiency; Reduce the expenditure in firing equipment and place; Be provided with and have two ring annular grooves at least, can be for the processing of (comprising stator) of different length motor casing.
