Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in fig. 1, the magnetic core 10 without removing the inner ring is provided with a magnetic core inner ring 12, the magnetic core inner ring 12 has an L-shaped raised head, the present embodiment utilizes the utility model provides an air gap magnetic core electric inner ring removing special tool removes the magnetic core inner ring 12 of the magnetic core 10.

As shown in fig. 2, the special tool for electric inner circle removal of the air gap magnetic core comprises a direct current motor 1 and a speed change gear set 2, the inner ring clamping head 3, the shell 8 and the motor switch 5 used for controlling the opening and closing of the direct current motor 1, the direct current motor 1 is connected with the speed change gear group 2 and used for driving the speed change gear group 2 to rotate, a groove 6 matched with the inner ring clamping head 3 is formed in the speed change gear group 2, the inner ring clamping head 3 is matched in the groove 6, a fixing screw 7 penetrates through the groove 6 and is matched in the inner ring clamping head 3, the inner ring clamping head 3 is fixed on the speed change gear group 2, the direct current motor 1 is located in the shell 8, the speed change gear group 2 outwards extends out of the shell 8, the inner ring clamping head 3 is located outside the shell 8, the end part of the inner ring clamping head 3 is provided with a clamping opening 4 matched with the magnetic core inner ring 12 and used for clamping and coiling the magnetic core inner ring 12, and the.
