Technical Field

[0002] The magnetic signal wheel is an important component of the automobile crankshaft. The sizes of magnetic signal wheels required for different types of automobile crankshafts are different. After the magnetic signal wheel is processed and produced, a magnetizing device is needed to magnetize the magnetic signal wheel. After magnetization, it can be put into use.

[0003] The existing magnetizing device for magnetizing the magnetic signal wheel is also very likely to be inconvenient to perform magnetizing according to the size of the magnetic signal wheel during use;

[0004] The reason for this problem is that the signal wheel consists of a signal wheel body and a magnetized rubber ring on the periphery. When magnetizing the signal wheel, it is necessary to make the inner wall of the magnetizing head fit with the magnetizing rubber ring for magnetization. The existing magnetizing head is annular, and its shape matches the shape of the signal wheel. The magnetizing head is sleeved on the outer wall of the signal wheel so that the magnetizing head contacts the signal wheel, and then the signal wheel can be magnetized. Due to the different sizes of magnetic signal wheels, magnetizing equipment with magnetizing heads of different sizes is required, which is not convenient for magnetizing signal wheels of different sizes, thereby reducing the convenience of using the magnetizing equipment. In view of the shortcomings of the existing technology, we propose a magnetizing device for magnetizing a magnetic signal wheel to solve the above problems. Utility Model Content
