A jig for handling automobile leaf springs

Abstract

The invention provides a clamp used for carrying an automobile leaf spring. The clamp comprises a clamping structure and a magnet. The clamping structure comprises a hanger rod, a fixed clamping jaw and a movable clamping jaw. The hanger rod further comprises a lifting ring and a connecting rod, the lifting ring is located at the top of the hanger rod and fixedly connected with one end of the connecting rod, and the connecting rod penetrates through the fixed clamping jaw and the magnet through a through hole in the fixed clamping jaw and a through hole in the magnet. The perpendicular distance between the end face of one end, far away from the lifting ring, of the connecting rod and the magnet is 4cm-8cm. The fixed clamping jaw is shaped like a Chinese character 'gong', the magnet is fixed to the fixed clamping jaw, the movable clamping jaw is M-shaped, the fixed clamping jaw is in hinge joint with the movable clamping jaw through a first hinge joint hole, and the movable clamping jaw is in hinge joint with the connecting rod through a second hinge joint hole which is formed between the fixed clamping jaw and the magnet. One end of the magnet is fixedly connected with the fixed clamping jaw, the other end is fixedly connected with a fixed rod arranged on the fixed clamping jaw, and the magnet is provided with a magnetic resistance switch. The clamp is high in clamping efficiency and automation degree and convenient to operate, and is exclusively used for carrying the automobile leaf spring.

Description

technical field [0001] The invention relates to a clamp specially used for handling leaf springs of automobiles, which belongs to the technical field of machinery. Background technique [0002] Automobile leaf spring is the most widely used elastic element in automobile suspension. It is an elastic beam with approximately equal strength composed of several alloy spring sheets of equal width but unequal length. The shape of the automobile leaf spring has the characteristics of flatness and small surface area per unit volume. The irregular shape makes it inconvenient for traditional clamping tools such as claws to tightly and firmly clamp the automobile leaf spring. [0003] Existing automobile leaf springs are heavy in weight. Generally, when the claws clamp the automobile leaf spring, the automobile leaf spring will slip due to its heavy weight. If the claws with very large clamping force are used, during the clamping process The claws are easy to damage the paint of the au...

The shape of the automobile leaf spring has the characteristics of flatness and small surface area per unit volume. The irregular shape makes it inconvenient for traditional clamping tools such as claws to tightly and firmly clamp the automobile leaf spring.

[0003] Existing automobile leaf springs are heavy in weight. Generally, when the claws clamp the automobile leaf spring, the automobile leaf spring will slip due to its heavy weight. If the claws with very large clamping force are used, during the clamping process The claws are easy to damage the paint of the automobile leaf spring, and even leave a gap on the automobile leaf spring, so that the automobile leaf spring is easy to be corroded, and also affects the appearance of the automobile leaf spring as a complete product, reducing the sales volume of the product. Therefore, the industry does not Claws are used to carry the automobile leaf spring, and magnets are often used to carry the automobile leaf spring, but the pure use of magnet suction to carry the automobile leaf spring will cause the magnet and the automobile leaf spring to slide relative to each other during the handling process, or even slip off, and the automobile leaf spring The change of the relative position with the magnet will cause the center of gravity of the leaf spring to shift, and it cannot be hoisted smoothly, and it will fall smoothly. When the car is put down, it will partially hit the ground and cause damage to the leaf spring of the car.
