[0002] In the past in the motor stator production field, the variable frequency motor stator compression mode is the external independent compression mechanism, along with the breakthrough of variable frequency motor technology, the motor size is constantly larger, and the compression force needed also increases, and continue to use the external independent compression mechanism will make the equipment too large, thereby leading to the equipment efficiency reduction, and the manufacturing cost increases a lot. SUMMARY
[0003] In order to overcome the above technical deficiencies, the utility model provides a large -scale variable frequency motor iron core compression device.
[0004] The utility model discloses a technical scheme is: a large -scale variable frequency motor iron core compression device, its characterized in that: the guide sleeve is fixedly connected with the support disc through screw, and the guide post is slidably connected with the guide sleeve and is fixedly connected with the compression inner ring through screw, and the positioning seat with the iron core is fixedly connected with the compression inner ring, and the reset spring is arranged between the compression inner ring and the support disc, the reset spring is installed on the outside of the guide sleeve, the driving disc with the roller assembly is installed on the compression outer ring, the roller assembly is composed of the compression wheel and the wheel shaft supported by the roller seat, the compression inner ring can rotate with the compression outer ring through the steel ball, the compression outer ring is fixedly connected with the compression guide disc through the connecting rod, the compression driving disc is rotatable in the groove, the compression driving disc is connected with the compression cylinder through the articulated member, the rotating shaft is fixedly connected with the base through the fixed seat, and the articulated base is fixedly connected with the compression cylinder and can rotate on the rotating shaft;The inner ring is connected by the outer ring rolling through the steel ball, the guide seat with the positioning cylinder is fixedly connected with the base through screw, the positioning cylinder is connected with the locking block, the support disc is fixedly connected with the outer ring, the driving wheel on the base is engaged with the outer ring, the guide disc is fixedly connected with the support disc, the limiting block is embedded in the guide disc sliding slot, the roller needle with the outer bushing is embedded in the limiting block pin hole, the bushing is embedded in the limiting drive ring groove, the drive handle is arranged on the limiting drive ring, and the cover plate is fixedly connected with the guide disc.
[0005] With the above technical scheme, after the iron core is installed to the positioning seat, the positioning cylinder pushes the locking block to slide in the guide seat and insert into the driving handle slot, the driving disc is fixed, at this time, the driving wheel drives the outer ring to rotate, the needle roller installed on the limiting block and the outer bushing move along the track of the outer ring sliding groove, the limiting block is extended and blocked at the right side of the iron core, the compression cylinder drives the hinged piece to rotate the compression driving disc, the compression driving disc has a slope boss, with the rotation of the compression driving disc, the compression roller is extruded, the compression disc fixed with the compression roller is extruded, the positioning seat installed with the iron core is installed on the compression inner ring, the compression inner ring is in rolling connection with the compression outer ring through the steel ball, thus the compression disc extruding the compression outer ring drives the iron core to move axially and finally contact the limiting block to realize the compression function. The device has the characteristics of simple and compact structure, low production cost and strong compression force, and is especially suitable for the production of large variable frequency motor products, and greatly improves the production efficiency.
