Summary of the invention
The technical problem to be solved in the present invention is to provide the heating jacket tooling of a kind of motor rotor, and this heating jacket tooling can carry out hot jacket operation within the heating waiting time to rotor, and completes placement and the removal operation of rotor, improves work efficiency.
The present invention solves the technical scheme of technical problem, a kind of heating jacket tooling of motor rotor, it includes for pressing the second cylinder 11 of rotating shaft 20, iron core 1 sensing heating being heated coil 5, the cylindrical positioning seat 2 of supporting iron core, the top of positioning seat is provided with flange, it is characterized in that, described heating jacket tooling also includes the base 3 of a tubular, heating coil is fixed on the left side of base, the top away from base, the bottom of heating coil have a distance, the second cylinder be arranged on the inverted L-shaped on the right side of base crank arm 12 horizontal direction arm on；The rotating disk 4 of one circle is placed in the recess on base top, is provided with two through holes symmetrically in the edge of rotating disk, is slidably fitted with positioning seat in through hole respectively；Being provided with the first cylinder 9 in the cavity of base, the piston rod 8 of the first cylinder and the center of circle of heating coil are on the same axis；Described rotating disk is driven by a motor 13, the each rotational angle of rotating disk is 180 degree, rotating disk is when the position of regulation stops, one positioning seat and the first cylinder coaxial, this positioning seat rises or falls with the first cylinder, the iron core making this positioning seat be supported puts in or exits heating coil, and another positioning seat is coaxial with the piston rod 10 of the second cylinder.
The operating procedure of the present invention is, when rotating disk stops in assigned position, makes the piston rod jacking of the first cylinder positioning seat above it, makes iron core put in heating coil and heat this iron core；At this moment loading onto rotating shaft on the iron core below the second cylinder, make the piston rod of the second cylinder decline, pressure rotating shaft enters in iron core, then makes the piston rod of the second cylinder reset, and is loaded on new iron core to the positioning seat below the second cylinder；When iron core arrives heat time heating time, making the piston rod of the first cylinder reset, positioning seat of its supporting relies on self gravitation to drop on rotating disk；Motor is made to stop after rotating 180 degree of angles, repeat the above steps.
The invention has the beneficial effects as follows, in the heating process of an iron core, can carry out another iron core being pressed into rotating shaft operation and iron core loading, unloading operation, the heating waiting time can be used, improve work efficiency.
