Description

Technical Field

[0001] The utility model relates to the technical field of yoke press-fitting, in particular to a clamping structure for press-fitting a multi-turn yoke. Background Art

[0002] A yoke usually refers to a soft magnetic material that does not produce a magnetic field (magnetic lines of force) by itself and only transmits magnetic lines of force in a magnetic circuit. The yoke is generally made of soft iron, A3 steel and soft magnetic alloys with relatively high magnetic permeability. In some special occasions, the yoke is also made of ferrite materials. The yoke is a yoke iron made of stacked silicon steel sheets. It is evenly and symmetrically distributed around the induction coil. Its function is to restrict the leakage magnetic field of the induction coil from diffusing outward and improve the efficiency of induction heating. In addition, it acts as a magnetic shield to reduce the heat of metal components such as the furnace frame and also serves to reinforce the inductor.

[0003] The existing clamping device for yoke press-fitting has certain disadvantages when in use. The existing clamping device can only clamp a single yoke when in use, which leads to low press-fitting efficiency and a longer production cycle. Secondly, when clamping the yoke, the position of the yoke needs to be manually adjusted to clamp its center. This setting has safety hazards and workers' hands are easily injured. In severe cases, it may directly lead to disability.

[0004] Therefore, in order to solve such problems, we propose a clamping structure for press-fitting a multi-turn yoke. Utility Model Content
