The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used to assemble magnetic cores.

The purpose of the invention is to reduce the labor intensity and increase the accuracy of assembly.

FIG. I shows the device section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a schematic depiction of the device, the expanded state; in fig. 4 shows a section BB in FIG. 3; in fig. 5 is a schematic depiction of the device, compressed; in fig. 6 is a sectional view BB in FIG. five.

The device for assembling the magnetic circuit of electric machines consists of a housing 1, in the grooves of which cams 2 and orientational elements 3 with directions 4 and locking 5 surfaces are located, piston 6 with projections 7 having inclined surfaces, and conical part 8, sleeve 9 and clamp 10, between which there is a magnetic core 11, springs 12, 13 and 14 with pressure elements 15-19. The housing 1 and the clamp 10 contain fastening elements - holes 20 and 21.

The device for assembling the magnetic cores operates in the following manner.

In the open device (Fig. 3), manually or with the help of the robot, the entire previously laminated sheet of the magnetic circuit 11 is freely mounted at the same time. When the device is open, both the cams 2 and the orienting elements 3 are displaced to the center and between the cams. 2 and the surface of the inner diameter of the magnetic core 11, as well as between the guide part 4 of the orienting elements 3 and the surface of the slots of the magnetic core 11, a guaranteed gap is formed (Fig. 4).

When lowering the upper plate 22 of the assembly press (not shown) with the clamp 10 fixed on it through the spring 12 and the pressure element 15, the compression force, which is much greater than the opposing force generated by the spring 13, is transmitted to the piston 6 and it starts to move in the axial direction downwards. In this case, the conical part 8 and the inclined protrusions 7 of the piston 6 act on the cams 2 and orienting elements 3, moving them radially away from the center. Due to the fact that the angle of inclination of the protrusions 7 is greater than the angle of the conical part 8 of the shaft 6, the movement of the orienting elements 3 occurs at a speed greater than the speed of movement of the cams 2. As a result, the fixing part 5 of the orienting elements 3 is first introduced into the slots of the magnetic circuit 11

and its angular fixation, and then the cams 2 reaching the surface of the calibrated inner diameter of the sleeve 9 and fixing the magnetic circuit 11 on the internal diameter (Fig. 6).

Due to the fact that the height of the sleeve 9 is equal to or greater than the length of the magnetic circuit 11, the cams 2, resting against the significant surface of the calibrated orifice of the sleeve 9, provide the formation of the exact internal diameter of the magnetic circuit 11.

After angular and diametrical fixing of the magnetic circuit 11, the upper plate 22 with the clamp 10, overcoming the resistance of the spring 12, continues to descend until the magnetic circuit 11 is compressed with a predetermined force (Figures 5, 1 and 2).

During the holding of the magnetic circuit 11 in the compressed state, the technological operation of its fastening is carried out by welding, gluing, mechanical elements or other methods.

After the bonding operation of the magnetic core 11 is completed, the plate 22 with the clamp 10 rises, the force from the spring 12 is removed and the piston under the influence of the spring 13 moves upward by an amount limited by element 19, and the cams 2 and orienting elements 3 under the influence of the spring 14 are displaced to the center and release the bonded the magnetic core 11 (Fig. 3 and 4), after which it can be manually or with the help of a robot freely removed from the device.
