Automatically finish the stator liftout attachment
Technical field: the invention belongs to the electrical machine equipment field, be specifically related to a kind of being used for to finish the stator liftout attachment automatically on the slot liner insertion machine.
Background technology: in the prior art, stator needs to take out after having inserted slot liner paper, and general employing manually sled pawl structure is finished, and the sled pawl is a lever construction, the rear end of manual depression sled pawl, and the front end of prizing pawl moves upward, and drives stator and rises.It exists inefficiency and center and angle location inaccurate.
Summary of the invention: the purpose of this invention is to provide a kind of can the rise automatically, the efficient height, center and angle location are finished the stator liftout attachment accurately automatically.
Technical scheme of the present invention is: a kind of stator liftout attachment of finishing automatically, it is characterized in that: die holder upper end in center is provided with the core rod positioning seat that matches with it, the core rod positioning seat is fixed on the mould, center die holder and core rod positioning seat cooperation place are provided with first sealing ring, core rod positioning seat upper end is provided with piston, the cylindrical of core rod positioning seat is provided with location core guide collar, the piston upper end is provided with cavity, the cylindrical of the core rod positioning seat between location core guide collar and the piston is provided with spring, outside piston and location core guide collar cylindrical all match with the location core, and the place of matching of piston and location core is provided with second sealing ring; The hole that is provided with in being provided with air vent hole in the die holder of center and locating core guide collar and piston is connected.
Owing to take above-mentioned technical pattern, during use, with stator pack into the location core on, gas enters in the cavity of piston end surface by the gas joint on the die holder of center along air vent hole, owing between piston and the location core sealing of O RunddichtringO is arranged, the cavity internal pressure increases, and promotes to move on the core of location, drives on the stator and moves, finish the work that ejects of stator, thereby have and can rise automatically, the efficient height, center and angle location be advantage accurately.
Description of drawings: technical solution of the present invention is elaborated below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present invention.
Embodiment: with reference to figure 1.A kind of stator liftout attachment of finishing automatically, it is characterized in that: die holder 9 upper ends in center are provided with the core rod positioning seat 5 that matches with it, core rod positioning seat 5 is fixed on the mould 8, center die holder and core rod positioning seat cooperation place are provided with first sealing ring 7, core rod positioning seat 5 upper ends are provided with piston 3, the cylindrical of core rod positioning seat 5 is provided with location core guide collar 6, piston 3 upper ends are provided with cavity, the cylindrical of the core rod positioning seat 5 between location core guide collar 6 and the piston 3 is provided with spring 4, piston 3 cylindricals and location core guide collar 6 cylindricals all match with location core 2, and the place of matching of piston and location core is provided with second sealing ring 11; The hole that is provided with in being provided with air vent hole 10 in the center die holder 9 and locating core guide collar 6 and piston 3 is connected.
During use, the stator ejecting structure is installed on the workbench of slot liner insertion machine, again stator 1 is packed into and locate on the core, join by gas joint 12 and source of the gas, gas enters by the air vent hole on the die holder of center in the cavity of piston end surface, owing between piston and the location core O type second sealing ring 11 is arranged, the cavity internal pressure increases, promote to move on the core of location, drive on the stator and move, finish the work that ejects of stator; Because the location core is fixed with one with location core guide collar, at this moment locatees on the core guide collar and move simultaneously, spring is compressed, and when stopping air feed, the cavity internal pressure reduces, spring reset, and the location core resets and gets final product.
