The invention discloses a dry-type transformer coil positioning device, which includes a left fixed frame and a right fixed frame for installing a coil winding drum; one side of the left fixed frame is provided with a rotating shaft that interferes with the coil winding drum and a fixed ring that cooperates with the coil winding drum to prevent the wound coil from sliding; one side of the right fixed frame is provided with a fixed shaft that fits with the coil winding drum, and the upper surface of the right fixed frame is installed with a pair of coils. The positioning mechanism for compressing the coils made; the upper surface of the left fixed frame is provided with a thrust mechanism for pushing the positioning mechanism to move to the right to reserve a gap for coil winding on the coil winding drum; the coil winding drum is provided with a The wire feeding mechanism that feeds the wire to the coil winding drum; every time the coil winding drum rotates, the thrust mechanism drives the positioning mechanism to move the width of the wire diameter to the coil winding direction, and the wire feeding mechanism moves the wire diameter to the coil winding direction width.
Description
technical field [0001] The invention relates to a device for winding transformer coils, in particular to a dry-type transformer coil positioning device. Background technique [0002] Since various industries have higher and higher requirements for the manufacturing quality of transformers, especially for coils, in order to improve their short-circuit resistance and other requirements, the coils are required to be tightly wound. Among them, the axial direction should be tight, and the radial direction should achieve zero margin. However, due to the characteristics of the coil structure in the existing transformer industry, most of the coils are wound by horizontal winding machines. There are problems that the radial direction of the coil winding is not solid, the axial direction is not tight, or the cross section of the copper wire is thinned. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the dry-type transformer coil posi...
