Mechanical arm used for clamping workpieces on production line

Abstract

The invention discloses a mechanical arm used for clamping workpieces on a production line. The mechanical arm comprises a connection plate, a rotation base, first swing arms, second swing arms, clamping devices and pull ropes. The rotation base is arranged on the lower side of the connection plate. A rack is installed in the connection plate in a sliding manner. A driving gear and a driven gear are symmetrically arranged in the rotation base. The number of the first swing arms is two. The second swing arms are hinged to the lower sides of the first swing arms. The clamping devices are arranged at the telescopic ends of the second swing arms. The interior of each clamping block is of a hollow structure. Multiple balls are arranged on the surface of each clamping block. According to the mechanical arm, rotation of the first swing arms and rotation of the second swing arms can be controlled at the same time, and therefore the mechanical arm can meet the practical clamping requirement, and the workpieces can be prevented from falling; and the telescopic balls are further arranged on the clamping devices, and therefore the uneven workpieces can also be attached to the clamping devices, and the workpieces are further prevented from falling.

Description

technical field [0001] The invention relates to the technical field of manipulators, in particular to a manipulator for clamping workpieces in a production line. Background technique [0002] The manipulator is a new type of device developed in the process of mechanization and automation. In the modern production process, manipulators are widely used in automatic production lines. The development and production of robots has become a new technology that has rapidly developed in the high-tech field. It further promotes the development of manipulators, enabling manipulators to Better realize the organic combination with mechanization and automation. Although the manipulator is not as flexible as the human hand, it has the characteristics of continuous repetitive work and labor, no fatigue, no fear of danger, and the power to grab and lift heavy objects is greater than that of the human hand. Therefore, the manipulator has been valued by many departments and is becoming more a...

Problems solved by technology

[0003] When the existing manipulator clamps the workpiece, because the adjustment mechanism of the manipulator itself is relatively simple, it is difficult for the manipulator to completely clamp the workpiece, which will easily cause the workpiece to fall off and cause unnecessary losses; because the surface of the workpiece on the production line is uneven, However, the surface of the existing manipulator clamping device is relatively smooth, and it is difficult to completely clamp the workpiece
