Description

Clamp device for winding transformer coil

Technical Field

The utility model belongs to the transformer field, especially, an anchor clamps device for coiling transformer coil.

Background

The traditional process for winding the transformer coil is to add two circular-arc-shaped wood dies on two corresponding side surfaces of a rotating shaft of a winding machine, the circular-arc-shaped wood dies are generally made of laminated wood, in order to ensure that transformers with the same capacity have uniform specifications, the laminated wood used for making the circular-arc-shaped wood dies needs to be subjected to drying, processing and other procedures, and the wood dies have the defects of low precision, heavy weight, easiness in cracking, difficulty in repeated use, long processing period and the like.

Disclosure of Invention

Detailed Description

As shown in fig. 1 and 2, the tooling fixture device for winding the transformer coil is composed of a fixture a (1) and a fixture b (2), wherein the fixture a (1) is composed of a bottom plate a (1-1) and a cover plate a (1-2), and is characterized in that the fixture a (1) is pillow-shaped.

As shown in fig. 2 and 3, the clamp b (2) is composed of a bottom plate b (2-1) and a cover plate b (2-2), and the shape and specification of the clamp a (1) and the clamp b (2) are the same and are respectively fixed on two opposite sides of the rotating shaft (3).

The section of the rotating shaft (3) is square, the rotating shaft is positioned in front of the winding machine and is controlled by the motor to rotate, and the cross section of the rotating shaft (3) and the clamps a (1) and b (2) on the two sides is oval and is consistent with the shape of the transformer iron core. The transformer core can be sleeved on the tooling device for winding.

Preferably, the tool clamp for winding the transformer coil can be formed by welding a steel plate and a steel cylinder so as to enhance the pressure resistance of the tool clamp.

Screw holes are formed in two opposite sides of the rotating shaft (3) at equal intervals, and the fixture devices with different sizes can be fixed so as to wind transformer coils with various specifications.
