Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a mechanical arm clamp used for forging precision forgings. Background Art

[0002] Forgings refer to forgings or blanks obtained by forging and deforming metal blanks. When loading or unloading metal blanks, the mechanical arm fixture is first fixed on the lifting equipment, and then the metal blank is clamped by the mechanical arm fixture, thereby driving the metal blank to move;

[0003] For example, a Chinese patent discloses a "mechanical arm clamp for forging precision forgings" with the announcement number: CN213256896U. The patent includes a clamping plate and two connecting rods. A clamping rod is fixedly connected to the side of the connecting rod. A clamping cavity for clamping the forging is formed between the two clamping rods. An adjusting component is provided on the clamping plate. When clamping the forging, the clamping plate is installed on the lifting equipment, and the adjusting component is used to drive the two connecting rods to separate from each other, thereby driving the clamping rods to separate from each other, increasing the clamping cavity, and then the forging is placed in the clamping cavity. The connecting rod is driven to move by the adjusting component, and the connecting rod moves from The two clamping rods are driven closer to each other, thereby reducing the clamping cavity. When the side of the clamping rod contacts the side of the forging, the forging is clamped, and then the equipment therein is used to lift the clamping plate, thereby pulling the forging to move. In this way, the size of the clamping cavity can be adjusted according to the size of the forging, which is convenient for clamping forgings of different sizes and is beneficial to improving the adaptability of forgings. However, this patent cannot clamp the forgings conveniently, and the forgings still need to be placed manually on the top of the clamp, which is not only labor-intensive but also inefficient. Therefore, it is necessary to design a mechanical arm clamp that can automatically lift and clamp. Utility Model Content
