Description

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 the cores of magnetic circuits of electrical machines, containing a sheet unloading mechanism, an assembly expanding mandrel with keys and groove gauges made in the form of a cylinder and fitted with flats located on opposite sides along the length of the working portion of the caliber, and having a tapered lead-in part is known. However, the known device does not provide accurate dosing of the packages of magnetic circuits of electric machines, which reduces their quality.

Another device for forming plates of plates 2 is known, containing its body, on which the abutment is fixed, a mandrel mounted in the body, a mechanism for cutting off the plates of the package, including sliding plates mounted on the hinges attached to the swivel arms and located eccentric.

This device is closest to the invention in terms of technical drying and the result achieved. However, construct2

Qi of the mandrel does not provide centering of the package along the inner diameter, which reduces the quality of the manufactured magnetic cores.

5 The aim of the invention is to improve the quality of the manufactured magnetic cores, by ensuring that the stack plates are centered on the inside diameter. The goal is achieved by the fact that the mandrel is made in the form of expanding cams interconnected by an elastic ring, inside of which there is an elastic element with a piston connected to the drive rod, and also containing pistons located inside the cams and spring-loaded to them in the radial direction, and the sliding plates are installed inside the plungers and are spring-loaded to them. The stop is mounted with the possibility of re-guiding its position relative to the sliding plates.

The dryness of the invention is illustrated in the drawings, where in FIG. 1 shows the general view of the device; in fig. 2 is a section along A-A of FIG. one.

Claims (2)

25 The device includes a housing 1, an adjustable stop 2, a limiting ring 3. Package 4 is located under the stop 2. Inside the case there are sliding claws 5 connected by a spring ring 6 installed under the slats 7. Inside the sliding cams 5 there are thin retractable legs 8 held in the cams and pins of the pins 9. The sheer of the elastic is taken 2-3 times less toli; On the one hand, thin ilastins are connected with a bracket 10, which is icricled to a spring 11, mounted on the plunger 12, with ustoviovlein in the cams. Nomesheio uirugoe ring 13, made from thick rubber, is placed between the plates and the bottom, and there is a cylindrical spring 14 between the plunger and cam 14. The stop collar contains fixing element 16, such as a locking screw with locknut, from the plunger on the cam. Inside the case there is an elastic element 17, an irimer of a hydroplastic, at the top of which there is a piston 18 mounted on a rod 19 of a pneumatic actuator 20. A device with an orienting pin, made in the form of a key 21. The device consists in following. The stop 2 is set to a position determined by the required height of the stack of plates to be assembled. The plate stop is fed to the device, iprpmer, from the bottom, is shifted upward along the shiopka 21 to the stop 2, and is pre-compressed to the force of the compressed package. After that, the pneumatic actuator 20 is turned on, the rod 19 moves the piston 18 downwards, the force is transmitted to the elastic element 17, as a result of which the extension cams 5 are advanced to produce centering of the assembled plate pack 4 according to the internal diameter. The force is then transmitted to the nupugers 12, which transmit the force through the ring 13 to the thinnest 1; the plates 8, the brown angels move out of the cams 5 and due to the small thickness the lower parts of the assembled package 4 are reliably fixed as a result of the individual package plates arranged opposite the thin 8. The formed packet 4 is transmitted to the next position. The package is removed due to the reverse switching of the non-flush 20, the removal of the piston 18, the return of the thin plastic 8 under the action of the spring 14, the movement of the plunger 12 with the bracket 10 and the cams 5 due to the spring-loaded hydraulic 17. The device is predetermined for stator package assemblies where centering along the inner diameter is required. It is also possible to use such a device for assembling packages of rotor plates with an external arrangement of sliding cams 5, which provide centering and cutting off the required height of the nace along the outer diameter. The presence of an expanding element, made in the form of sliding cams, provides precise centering of the flexible package of the magnetic core and its diameter, for example, for the stator in the inner, and for the rotor, in the outer. The presence of thin retractable elasters, simulated in cams, provides accurate dosing of the plate array of the magnetic core. The technical and economic advantages of the proposed invention over the known ones also consist in increasing the reliability and the metabolic network of the formation of magnetowires. Claim 1. A device for packing nlastin magnets of electrical masinages, comprising a housing on which is fixed, an alignment installed in the housing, a mechanism for cutting off ilastines of the package including sliding plates located inside the mandrel, characterized in that, in order to improve the quality of manufactured the magnetic cores by providing the centering of the plates of the package to the inner diameter, the mandrel is made in the form of expanding cams interconnected by an elastic ring, inside which the dix norshnem resilient element connected to the actuator stem. 2. The device according to claim 1, characterized in that it contains plungers located inside the cams and loaded to them in the radial direction, and retractable plaetines are installed inside the plungers and spring-loaded to them. 3. The device of claim 1, characterized in that the stop is installed with the possibility of adjusting its position relative to the sliding nlastin.
