(54) DEVICE FOR ASSEMBLY OF ELECTRICAL ANCHOR WINDING

MACHINES WITH COLLECTOR

one

The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used in the electrical industry.

A device for assembling a winding of a core of an electric machine with a manifold, containing a technological ring with grooves and orienting elements located at the end of the technological ring, punches for erecting the ends of the winding in the grooves of the collector, and a mechanism for pressing the collector onto the shaft of the PI is known.

However, when assembling the core winding with a collector with a known device, it becomes necessary to disorientate the ends after pressing the collector onto the shaft, and then they must be re-oriented so that the ends of the winding in the grooves of the collector plates are set and fixed. This disadvantage is due to the fact that when pressing the collector from the end, only the inner row of the ends of the winding enters the grooves, and the upper row is above the collector plates. The presence of additional operations (rearrangement and orientation of the ends) reduces productivity.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the orienting elements are made in the form of wedges with their radial movement driven relative to the technological 1 ring and located in the slots of the technological ring.

FIG. 1 shows a device for

10 assembly winding core with a collector before pressing the collector on the shaft of the core; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 2; in fig. 4 - device for

15 assemblies of the winding of the core with the collector after pressing the collector on the upper cor.

Device for assembling the winding of electric machines with collector

20 contains a technological ring 1 with grooves radially arranged around the circumference and mounted on the device case 1 not shown) from the end of the technological ring in its grooves

25, orienting elements .2 are provided, made in the form of wedges (FIG. 2) with the drive of their radial movement relative to the technological ring (not shown). In grooves

30 technological rings are installed

guide members 3 for orienting the manifold relative to the process ring. Between the orienting elements 2, punches 4 are located for rolling the ends of the winding in the collector slots. After pressing the collector 5 onto the shaft 6 of the core 7 by a pressing mechanism (not shown). 1 Anchor -7 has. Output ends of winding 8 and 9.

The device for assembling the winding of the core of electric machines with a collector operates as follows.

An anchor 7 is installed in a special device, while the orienting elements 2 are inserted between the ends of the winding 8 and 9 in the zone of the transition radius of the frontal part into the slot portion of the winding. The drive moves the orientation elements 2 in the radial direction relative to the technological ring 1 until the wedge of the orienting elements clamp the winding ends of the cores 8 and 9. Then the collector 5 is mounted on the shaft 6 of the core 7 and align it with the slots relative to what the press-in mechanism is. press the collector on the shaft of the core. Then the punches 4, moving in the radial direction, lay and roll the ends of the winding 8 and 9

the core in the collector slots, after which the punches 4 and orienting elements 2 are retracted to the initial position, and the measles 7 is removed from the device.

The proposed device allows improving productivity by simultaneously inserting the ends of the core winding into the grooves of the collector plates and rolling them into the slots.
