[0002] Leaf spring, also known as leaf spring or automobile leaf spring, is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy spring leaves of equal width but unequal length. The advantages of leaf spring include simple structure, reliable operation, low cost and convenient maintenance. However, it also has some disadvantages, such as it can only be used for non-independent suspension, heavy weight, high rigidity, poor comfort, long longitudinal dimension, which is not conducive to shortening the front and rear overhangs of the car, and the leaf spring pins at the connection with the frame are easy to wear.

[0003] The main function of the leaf spring is to connect the axle and the frame, bear the bearing force, traction, braking force and lateral force of the axle on the frame, and reduce the impact of the vehicle during driving. The auxiliary leaf spring is installed above the main leaf spring to assist in bearing the load. When the vehicle is fully loaded, the main and auxiliary leaf springs work together to enhance the load-bearing capacity of the main leaf spring. In addition, the leaf spring also has the function of absorbing vibration and impact energy. The production process of the leaf spring generally includes cutting, drilling, ear rolling, quenching, tempering, shot peening, assembly, pre-stressing, painting and other steps.

[0004] Before performing surface treatment such as painting on the leaf spring, the surface of the steel plate needs to be polished. However, since the steel plate has a certain curvature, the staff needs to use a handheld grinder to polish it, and it is difficult to use an automated device for polishing. In view of this, the present application proposes a leaf spring surface treatment device. Utility Model Content
