During practical use, after the base is fixed, linear driving devices such as air cylinders are arranged below the limiting seats, and driving terminals such as air cylinder pistons are aligned with the base. The piston jacks the base to drive the sliding block to vertically move upwards, so that the terminal of the spreading part moves towards the central axis direction of the sliding block (namely, the circumferential radius formed by the terminal of the spreading part is reduced). The magnetic shoes are sequentially arranged on the magnetic shoe die and are clamped with the movable part of the spreading piece through the magnetic shoe die, or can be matched with an auxiliary connecting structure of the spreading piece (such as a magnet buckle for magnetic adsorption) and be connected with the terminal of the spreading piece. After the magnetic shoe is assembled on the base, the outer side of the magnetic shoe is coated with glue and sleeved with a stainless steel sleeve. And controlling the cylinder piston to return to the original position, and releasing the jacking of the base. The base descends under the action of the spring until the convex edge of the base is pressed and connected with the limiting guide block. The connecting rod drives the sliding block to vertically move downwards, so that the opening piece terminal moves towards the direction far away from the central axis of the sliding block (namely the circumferential radius formed by the opening piece terminal is increased), and the magnetic shoe is horizontally pushed to the inner wall of the stainless steel sleeve body. Because the opening pieces synchronously move at equal intervals, the magnetic shoes can automatically finish centering adjustment after being attached to the stainless steel sleeve, thereby ensuring the uniform distribution of the magnetic shoes in the stainless steel sleeve and ensuring the stable gap of the magnetic shoes; meanwhile, the automatic centering adjustment also ensures that the joint strength of each magnetic shoe and the inner wall of the sleeve body is the same, so that the gluing thickness is uniform, and the quality of a motor product is ensured.
