Description

The invention relates to process equipment for the production of electric machine cores and can be used in mechanical engineering and electrical engineering.

The purpose of the invention is to increase productivity.

Fig, 1 shows a general view of the machine; figure 2 is a section aa of figure 1, the conveyor plates; a Z-view B in Fig. 1, a mechanism for discharging plates; figure 4 - node I in figure 1, the mechanism of crimping; figure 5 - shaft loading mechanism; figure 6 - section bb In figure 5.

The machine for making the electric motor core contains the unwinder 1. the correct-feeding device 2, the press 3, the conveyor 4 of the plates consisting of the guides 5 and the orienting plates 6, the mechanism 7 for sending the plates consisting of the guide tube 8, the movable jaws 9, able to rotate on axis 10, slider 11, sensor 12, mechanism 13 for cutting off a stack of plates connected through a system of gear wheels with a turntable 14. Turntable 14 has four

The working positions in which the satellites 15 are installed, the satellite 15 has two guides 16 to maintain the orientation of the package and can be moved along the guides 17, where the springs 18 are installed, which are in the idle state without compression. The satellites 15 are located on spring-loaded spherical supports 19. The crimping mechanism 20 consists of a hydraulic cylinder 21, pillars 22, a subcap 23, a housing 24, springs 25, a slide 26 and a punch 27. The machine also contains a frame 28, a table drive 29 containing a hydraulic cylinder 30 , and a shaft loading mechanism consisting of an adjustable sleeve 31, an axis 32, a pin 33, lamellar springs 34, a holder 35, a cone 36, a gate 37 and pneumatic cylinders Hi and Pa.

The machine works as follows.

From the unwinder 1, the tape by the correcting-feeding device 2 is fed to the working area of the press 3, from where the cut-off plates of the core along the conveyor 4 plates, the slides along the guides 5 and the orienting plates 6, enter the mechanism 7 for distributing the plates, where the sensor 12 is turned on

nor the drive of the mechanism for filing the plates (hereinafter the sensors are similar). As soon as the plates of the core along the guide tube 8 reach a certain level, the sensor 12 triggers and sends a command to drive the drive mechanism 7. When the drive actuates, the slide 11 moves up and presses the bevels of the movable jaws 9, thereby causing the latter to rotate around the axes 10 and moving upwards, in this case a column of plates of a certain height is cut off, which moves up to the stop in the mandrel of the mechanism 13 for cutting off the plate pack. When the pressure reaches a certain level, the sensor responds and his team is cutting off a package of plates of a certain height. After a certain time, a command is given to lower the movable jaws 9 and the command to the hydraulic cylinder 30, which rotates the table 14 through the table drive 29, and through the gear unit and the plate pack cutting mechanism 13 to a predetermined angle, the position of the cut-off mechanism with the cut-off bag and positions on the turntable 14 are aligned. While at the other position of the cutting mechanism 13, the next package is cut off, here the pneumatic cylinder rod (not shown) presses the lower end of the satellite 15 and raises it along the guides 17, while the guides 16 of the satellite 15 go into the grooves of the cut-off package and when the satellite 15 reaches a certain height, the sensor is triggered, the springs of the mandrel of the cut-off mechanism 13 will push the cut-off package onto the satellite 15. After a certain time, the pneumatic cylinder rod (not shown) is lowered and the satellite 15 is lowered by the action of the springs 18 jack. The team rotates the table 14 in this way and the cut-off bag moves to the next position, and the empty position of the table becomes under the newly cut-off packet (work at all positions is parallel).

In the second position, the shaft is loaded into the plate pack. At the command, the pneumatic cylinder rod PC rises and turns around its own axis by a certain angle the gate 37, while the gate 37 cuts off one shaft and under the weight of its own weight is lowered into the adjustable sleeve 31, and along it into the plate pack (figure 5) until it stops the shaft cone at the upper end of the plates, after a certain time, a command is given to the pneumatic cylinder rod PZ, which is lowered and, with a cone 36, spreads the sleeve 31 by a certain angle, while the table 14 rotates and the bag with the shaft moves

to the third position, and the piston rod P2 returns to its original position. When this plate springs 34, mounted on the holder 35, return divorced parts of the sleeve

31 to their original position, where they are centered on pin 33, maintaining the gap AS, turning on axis 32.

At the third position, the package height is monitored during pressure testing (not

shown) and pressing the shaft into the package, i.e. assembly. On command, the body 24 (FIG. 4) moves downwardly through the stem of the hydraulic cylinder 21, the slider 26, in contact with the upper end of the bag, begins to move upwards

until it stops at the end face of the punch 27. Spring 25 is compressed on the upper end of the package, warning the package to be blown out, and the punch 27 presses the shaft into the plate package along the shoulder of the largest

shaft diameter and simultaneously compresses the package. Since the gap ASi L S2, the satellite 15 presses the supports 19 until the lower end of the satellite 15 is in contact with the submount 23, i.e. the pressure load is perceived by the bed 28, not by the turntable 14.

At the next turn of the table 14, the collected measles enters the fourth position where the unloading of the core to the

tape drive (not shown). All movements of the line actuators are carried out on commands from the sensors.
