Mechanical arm

Abstract

The invention discloses a mechanical arm comprising a base, a swinging air cylinder, a swinging arm assembly, a synchronous belt, a motor and an air cylinder. The cylinder body part of the swinging air cylinder is rotatably connected to the base; a free end of the swinging air cylinder is synchronously connected with a first synchronous belt wheel; one end of the swinging arm assembly is synchronously connected with the free end of the swinging air cylinder and the other end of the swinging arm assembly is rotatably provided with a second synchronous belt wheel; the synchronous belt is arranged on the first synchronous belt wheel and the second synchronous belt wheel in a winding manner; the body of the motor is synchronously connected onto the second synchronous belt wheel; the cylinder body part of the air cylinder is synchronously connected onto a rotating shaft of the motor; and the free end of the air cylinder is connected with two opposite grippers. In the mechanical arm disclosed by the invention, the swinging air cylinder is adopted as a power source and is used for driving two joints of two mechanical arms to rotate, so that volumes of the mechanical arms are reduced, and the mechanical arms are lighter in weight and can meet requirements of utilization in teaching demonstration and in other smaller industrial equipment; and meanwhile, the mechanical arm has higher degree of automation and higher operation precision.

Description

[0001] technical field [0002] The invention relates to a mechanical device, in particular to a mechanical arm. [0003] Background technique [0004] The robotic arm is a commonly used device in the process of automatic production and processing, which can realize flexible snatching and other actions. [0005] At present, the mechanical arm usually has multiple rotating joints, and the rotation of each joint is realized by a stepping motor or a servo motor. Since the stepping motor or servo motor is usually large in size, this requires each joint of the mechanical arm to Some parts have a larger volume to facilitate the installation of stepper motors or servo motors. However, in the teaching process, the equipment is required to have a smaller volume and portability. Obviously, the structure of the existing mechanical arm has a larger volume. Inability to meet the requirements of teaching demonstrations. [0006] Contents of the invention [0007] Aiming at the defic...
