Description

Stator coil winding machine for insert-compatible weighing of stator coil sets for electric motors. The invention relates to a method and a device for Insert-compatible winding of stator coil sets for electric motors in one operation andfor the automatic transfer of a finished stator coil set by a transfer device into an inserter for the purpose of insertion into the stator slots of an electric motor changeover During a winding process according to the prior art is another method known and considered.

It is a transfer device onto which stator coils - subsets can be wound in a way that is suitable for the insert.

All known devices do not allow a complete set of stator coils to be transferred to an inserter for the purpose of guiding into the stator slots of an electric motor stand. a complete stator coil set located on the magazine is automatically transferred to an inserter during a winding process.

The object is achieved according to the invention in that a set of pins or fittings is arranged in a machine frame and in a magazine - axially displaceably, and is wound by a rotating wire guide in such a way that a stator coil is created, and that the set of pins or fittings after the winding process is moved away from the rotating wire guide, so that the stator coil located on the set of pins or fittings is held in the magazine in a clamping block. The arrangement of several terminal blocks on the magazine enables short and uninterrupted wire connections from coil to coil and an arrangement of the stator coil set on the magazine suitable for insert. and the arrangement of multiple - clamping blocks on the magazine.

The arrangement of two or more interchangeable magazines in the swivel head enables a set of static reels to be transferred to an inserter during a winding process. The solution to the problem is shown in the drawings on page 7 to page 10 and is described in more detail below. Fig. 4 shows in a side view and partially drawn in section, a stator coil winding machine in the form of an automatic rotary table. Fig. 5 shows a view of a magazine. Fig. 6 shows a magazine in section II - II.

Fig. 7 shows a terminal block in section III - III.

Fig-. 8 shows a magazine with a plurality of sets of pins and multiple - terminal blocks in the view.

Fig. 9-_zeigt a multiple - in the terminal block section IV - IV. Figures 10 and 11 shows two different pictures of winding Statorspulensätzen.. The swivel head 3 of the stator coil winding machine can be swiveled in the axis 2. In the swivel head 3 , two magazines 19 are arranged in mirror image to one another. The magazines 19 are interchangeable with one another.

A rotating wire guide 9 is arranged in the axis of rotation C.

In the pivot head 3 , a set of pins 1 is axially displaceable with respect to the axis of rotation C of the revolving wire guide 9. At the beginning of a winding process, the beginning of the coil wire is held in a wire clamping and cutting device located next to the magazine 19.

Then the set of pins 1, pneumatically operated, is moved out of the machine stand 29.

It passes through the bores 30 in the magazine plate 22 in the area of the rotating wire guide g. The set of pins 1 then begins to be wound by the rotating wire guide g. After the required turns have been wound onto the set of pins 1 , the circulating wire guide 9 is stopped. The wound set of pins 1 is then moved back axially into the machine frame 29, so far that the pin ends are behind the magazine plate 22.

While the set of pins 1 is being retracted, the finished bobbin is guided into the clamping tongs 23 which are open at the side next to the clamping block 20. 7 shows the arrangement of the clamping tongs 23 to form a clamping block 20. The clamping tongs 23 are held open in the idle state by compression springs: 24 and after the set of pins 1 has moved back, they are closed by pneumatically actuated clamping bolts 25 - so that the coil is laterally on the Terminal block 20 is held.

Now that begins . Winding the second coil.

First, the magazine 19 is swiveled further around a clamping station, so that an empty clamping block 20 with open clamping tongs 23 is in the area of the rotating wire guide 9 . Then the set of pins 1 is again shifted axially out of the machine frame 29 towards the rotating wire guide 9 , and the process, as when winding the first coil, is repeated. As soon as all six clamping stations have been wound in this way, the swivel head is swiveled 3-horizontally through 180 degrees. The end of the wire between the last wound coil and the revolving wire guide 9 gets into a wire clamping and cutting device.

. Now there is an empty magazine 19 in front of the rotating wire guide 9 and a new winding process begins.

At the start of the new winding operation of the wire in the wire clamping is - and separating means separately, and the fully wound magazine 19 can be removed from the machine. In Fig. 10 and 11 , two typical winding patterns of stator coil sets are shown. The winding pattern in FIG. 10 shows that the revolving wire guide 9 has wound from clamping station to clamping station in alternating rotation. 11 shows a winding pattern with the same direction of rotation of the revolving wire guide 9. The short and uninterrupted wire connections from reel to reel, as a result of the arrangement of the sets of pins 1 to one another in accordance with the insert, are also clear here.
