[0015] (3) Beneficial effects

[0016] The utility model provides an infrared soft magnetic clamping device with the following beneficial effects:

[0017] 1. The infrared soft magnetic clamping device sets a clamping component to correspond the test coil to the hollow chamber, and controls the cross slide mechanism to move the clamping component downward, so that the test coil can enter between the four arc-shaped pieces, and controls the strength of the electric push rod to make the arc-shaped piece cooperate with the small arm, middle arm and large arm to stably clamp the test coil. Since the small arm, middle arm and large arm are elastically connected, the clamping force of the electric push rod has a variety of elastic buffers, which can not only stably clamp the test coil but also protect the soft magnet and prevent the soft magnet from being deformed by clamping. The structure of the arc-shaped piece can increase the contact force with the test coil, and the arc-shaped structure can just realize the insertion of the test coil before clamping, avoiding the direct clamping in the prior art. Direct clamping is not easy to control the amount of movement and is prone to damage to the soft magnet.

[0018] 2. The infrared soft magnetic clamping device is equipped with an infrared receiver. When the central processing chamber moves laterally, the infrared transmitter can cooperate with the infrared receiver on the outer shell to accurately control the moving position, and can also cooperate with the infrared receiver on the test bench to accurately determine the test position.

[0032] A cross column 709 is provided in the hollow chamber 702 . The cross column 709 is fixed to the upper surface of the central processing chamber 701 . The fixed end of the electric push rod 707 is hinged to the upper end of the cross column 709 .
