Description

The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used in the electrical and automotive industries for assembling a winding with a collector.

A device for assembling a winding Core with a collector is known, which contains a technological ring with grooves and orienting elements located at the end of the technological ring, punches for rolling the ends of the winding in the slots of the collector and a mechanism for pressing the collector onto the shaft G1 3

However, it is impossible to obtain high quality winding on this device when assembling a winding with a collector made of multi-turn sections of small cross-section, since the ends of the sections after winding the core of the cross-section are arbitrary (fluffed)

And the front part gets enlarged,

It is also known a device for requesting the removal of the ends of the sections into the grooves of the collector, comprising a housing in which guide and pressing elements are arranged, adapted for mounting the core, and the actuator 21,

However, the known device is mainly suitable for pressing in the ends of rigid windings which are previously divorced in a collector pitch, and pressing in the ends of the windings from a small cross-section wire requires additional 15 to orient the ends of the sections relative to the slots of the collector, which reduces labor productivity. In addition, the frontal part is also increased due to the winding of the winding.

The purpose of the invention is to increase productivity and improve quality by reducing the frontal part of the winding. 98 The goal is achieved by the fact that in the device the device for installing the core is made in the form of a glass with radial grooves on the inner cylindrical surface provided with a drive for its rotation, and forming elements for the winding frontal part mounted on the bottom of the glass while the fixing elements are made in. as plates with lead-in chamfers, located in the radial grooves of the glass. Figure 1 shows the device, the general view; in fig, 2-- section aa in fig 1; Fig. 3, section B-B in Fig. 1o. The device for assembling the winding of the core with the collector comprises a housing 1 in which guide 2 and pressing 3 elements are installed, a device for installing the corr A, made in the form of a cup 5 with radial grooves 6 on the inner cylindrical surface and the molding elements 7 for the frontal part 8 of the winding 9 installed at the bottom of the glass, the locking elements 10 according to the number of grooves 11 bore 4 and the actuator 12, made in the form of a rotary disk. The guide elements 2 are made in the form of strips and are connected with the drive 12 of their radial movement. In the grooves between the bar (MI, pressing elements 3 (punches) are installed for laying and rolling the outer ends 13 of the winding in the slots of the collector 1) The punches are connected with a drive of their radials-south movement in the form of a disk 15. Rigidly mounted in the radial grooves of the beaker 5 The beaker is equipped with a drive 1b for its turn of the rack type.The device also contains a spring-loaded pusher 17 for installing the core k in the beaker 5 The device operates as follows: Anchor with external ends The 13 windings are not divorced along the grooves of the collector AND, set into the bore of the glass 5 so that the fixing elements 10 fit into the grooves 11 of the core. When installing the core, the guide rails 2 and the punches 3 are separated from the center. prior to the forming elements 7, the plates 10 set off the winding 9 in the slots 11 of the core, seal

Claims (1)

The core is made in the form of a glass with radial grooves on the inner cylindrical surface, provided with a drive for its rotation, and forming elements for the frontal part of the winding installed at the bottom of the glass, while the fixing elements are made in the wire plate with lead-in chamfers. 94 and thereby reducing the frontal part of the winding 8. After that, the guide bars 2 are reduced to the cockerers of the Il collector and the ends 13 of the winding are fixed relative to the slots of the collector. Then, using the actuator 16, the cup 5 is turned together with the bark 4 and the collector k with respect to the non-adjustable guide bars 2 at the wiring angle of the winding ends 13 along the grooves of the collector U, Anchor i moves upwards by a certain amount J (FIG.), And cock area -. The lecturer k enters the plane of the punches 3, and the frontal suit 8 of the winding of the core is compacted due to the tightening of the ends of the winding in the process of their wiring. After this, the punches 3 descend toward the center of the collector H, the ends 13 of the winding are pushed into the grooves of the collector I and rolled into them. Next, the punches 3 and Llanca 2 are dispersed from the center of the collector, the pusher-17 rises up and the measles are pushed out of the cup 5 (the push drive is not shown. The use of the proposed device improves the performance due to the automatic end orientation of both hard and soft windings made from a small cross-section wire relative to the collector slots and improves the quality of kop by compacting the winding and reducing its frontal portion.
