Description

The invention relates to a positioning device for aligning at least one conductor body and a method for aligning at least one conductor body by means of a positioning device.

Methods and devices for producing bar windings for electric motors or electric generators are known, in which electrically conductive conductor bodies are inserted into slots in a laminated core. Such a device is known, for example from DE 26 48 260 ,

The ladder body or Stableiter called are usually bent U-shaped and arranged with a first end portion in grooves of the laminated core. In order to electrically insulate the conductor bodies from the laminated core, the conductive bodies comprise electrically insulating coatings at first end portions.

In the methods and devices known from the prior art, the conductor bodies are inserted into the grooves of the laminated cores and rotated there after insertion into their final position. In this case, due to the movement of the conductor bodies within the grooves, it can never be completely avoided that the coatings of the conductor bodies are mechanically stressed and, for example, scratched. This can cause rejects.

An object of an embodiment of the invention is to propose a method and a device with which the generation of rejects is at least reduced.

This object is achieved by a positioning device for aligning at least one conductor body, with at least one planar base plate and with at least one receiving unit, which comprises at least one receiving means, which rotates about a transverse to the plane of the base plate, and in particular extending through the receiving means, rotation axis the base plate can be fixed or fixed and on which at least one of the at least one conductor body can be fixed, wherein the at least one receiving means can be transferred from a basic position, in which at least one of the at least one conductor body can be arranged or arranged on the at least one receiving means, into a joining position, in particular, is rotatable, in which the at least one conductor body comprises an actual position and / or actual orientation which corresponds to a desired position and / or intended orientation of the at least one conductor body on or in a drum body of an electric machine corresponds to.

Characterized in that the conductor body can be arranged in a receiving means, which is rotatably arranged with respect to the base plate and in that the receiving means from the basic position can be transferred to the joining position, no relative movement between the conductor body and the receiving means after arranging the conductor body in the receiving means Ladder body and receiving means instead. As a result, the risk of mechanical stress, in particular damage, of the conductor body, in particular the surface of the conductor body, is reduced.

The conductor body can basically be configured as desired. If the conductor body comprises an element of an electromagnet or generator, it may comprise an electrically conductive conductor body. In addition, the conductor body may comprise any contour. It proves to be advantageous if the conductor body comprises a U-shaped contour.

The drum body may comprise a laminated core.

In principle, the receiving means can be of any desired design provided that it fulfills the function of being able to fix the conductor body to itself.

The receiving means can be produced simply and inexpensively if the at least one receiving means comprises at least one recess extending parallel to the axis of rotation, into which the conductor body can be inserted with a corresponding, in particular complementary, formed, in particular rod-shaped, first end section and at least against movement transversely to the direction of rotation axis is determinable.

In such a case, the conductor body can be arranged by simply inserting its first end portion into the recess on the receiving means.

In order to further reduce damage to the conductor body, in particular the first end portion of the conductor body, it proves to be advantageous if the at least one receiving unit comprises at least one protection element arranged in the recess, which comprises a material which has a lower abrasion resistance than the first End portion of the conductor body and / or a first end portion of the conductor body, in particular electrically insulating, surrounded coating.

Step a. can be carried out "if necessary". This means that the at least one receiving means is first transferred to the basic position if, for example, it is not arranged in the basic position at the beginning of the method. When the pick-up means is in the home position, it may be desirable to perform step a. be waived.

In addition, in a further development of the method, fixing or fixing of the at least one conductor body in the joining position is provided by at least one cuff-type fixing means.
