Description

The invention relates to technological equipment for the manufacture of electric machines, in particular for transferring a set of sections when laying single-turn sections into slots, and can be used in the electrical industry.

A known machine for producing and laying single-turn sections, which comprises a mechanism for transferring a set of sections and a mechanism for supporting the ends of sections with guide cams 1,

However, this design of the mechanism for transferring a set of sections does not allow to obtain high quality products and is difficult to manufacture.

The closest to the proposed technical essence and the achieved result is a device for transferring a set of sections of the winding of an electrical process, containing a mechanism for supporting the end

sections with guide cams and a mechanism for gripping sections with a drive of its reciprocating movement .2,

The mechanism for capturing and transferring sections contains a movable collet. When it clamps the frontal part of the sections, a residual deformation of the section profile occurs. In addition, the lack of self-installation of the collet along the frontal part of the sections leads to the misalignment of the axes of the extracted sections to their deformation, which reduces the quality of manufacture of the windings.

The aim of the invention is to improve the manufacturing quality of the windings.

The goal is achieved by the fact that the mechanism for gripping sections is made in the form of a sleeve with longitudinal stepped holes and with pins located in these holes, one end of each of which is bent, and on the other side of the mechanism to support the sections perform a protrusion drive with fingers in contact with the bent ends of the pins.

Fig. 1 shows a device for transferring a set of sections, a pro2 is a turn longitudinal section; in fig. ny pin; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. 1, the device comprises a movable element i coping on which a guide bushing 2 with stepped holes 3 is fixed. In the latter, there are mounted retaining pins 4 with a protrusion 5 (fig. 2) at one end. The other end 6 engages with the fingers 7 of the swivel disk 8 (FIG. 3). . The mechanism 9 for supporting the ends of the sections is provided with guide cams 10. The diameter of the rotary Pty 4 on the side of the protrusion 5 is equal to the gap between the center of the front, and the size of the protrusion 5 does not exceed the thickness of the section's profile (Fig. 4). The device works as follows. When moving the movable element 1 to the set of sections, the pivot pins 4 with the protrusions 5 freely, self-aligning along the frontal part of the set of sections, enter into the space between the sections, due to the fact that the stiffness of the pins inserted into the stepped holes 3 of the guide sleeve 2 less stiffness of the frontal part of the sections. This allows the ends of the pivot pins 4 with the protrusions 5 to have two degrees of freedom within the elastic deformations and gaps, and therefore self-aligning between the sections without the deformation of the latter. Moving: the movable element 1 is carried out until the front end of the guide sleeve 2 touches the section. When the disc 8 is turned, the fingers 7, acting on the end 6 of the rotary pin 4, rotate the pin, with each protrusion 5 engaging with the frontal part of the adjacent section. When the movable element 1 of the device for transferring a set of sections is retracted, the pins 4 remove sections, while the ends of the sections are supported by guides inserted between them.

cams 10 support mechanism 9. When inserting the sections, the front end of the guide sleeve 2 inserts the sections into the grooves of the product, and the cams 10 of the support mechanism 9 are withdrawn from the sections. After the sections are laid down, the disk 8 rotates in the opposite direction from the engagement of sections with the protrusions 5 of the pivot pins 4, and moves the movable element 1 of the section set transfer device to its original position. The use of the proposed device in comparison with the well-known structures allows improving the quality of the windings by eliminating the deformation of the profile of the frontal part of the sections and preserving the insulating gaps. This is due to the fact that the profile of the frontal part of the sections is not clamped, but covered on even sides; on both sides of the pivot pins, on the inner side, the protrusions of the pins, and on the i side, on the front end of the guide bush. An apparatus for transferring a set of winding sections of electric machines, comprising a mechanism for supporting the ends of sections with guide cams and a mechanism for gripping sections with a drive of its reciprocating movement, characterized in that in order to increase the quality of manufacturing windings, m the mechanism for gripping the sections is made in the form of a sleeve with longitudinal stepped holes and with pins located in these holes, one end of each of which is bent and on the other side of the mechanism l Support all sections vsholnen protrusion, and the turntable with the fingers in contact with the curved ends of the pins.
