Simple mechanical arm

Abstract

The invention provides a simple mechanical arm and belongs to the technical field of mechanical arms. The simple mechanical arm solves the technical problems that an existing mechanical arm is large in size, complex in structure and inflexible to operate. Thee simple mechanical arm comprises a mechanical arm assembly, a first control mechanism, a front arm body, a second control mechanism, a third control mechanism, a main arm, a fourth control mechanism and a base. The mechanical arm assembly is used for clamping workpieces. The first control mechanism controls the mechanical arm assembly to rotate circumferentially and swing. One end of the front arm body is connected with the first control mechanism. The second control mechanism is capable of controlling the main arm body to rotate. The third control mechanism is capable of controlling the second control mechanism to swing in the vertical plane. One end of the main arm body is fixedly connected with the third control mechanism. The fourth control mechanism is capable of controlling the main arm body to swing in the vertical plane. The base is rotatable, and the fourth control mechanism is arranged on the base. Through the four control mechanisms, the mechanical arm can move flexibly in different planes, the simple mechanical arm is wider in movement range and higher in flexibility, and therefore the working efficiency of the mechanical arm is improved.

Description

technical field [0001] The invention belongs to the technical field of manipulators and relates to a simple manipulator. Background technique [0002] The manipulator is an automatic production equipment that replaces people in the industry to complete large-scale and high-quality requirements. It includes a hand and a movement mechanism. The movement mechanism includes multiple connected arms, and various rotations, swings, movements or compound movements are completed through the arms. To achieve the prescribed action, change the position and posture of the grasped object. [0003] Existing manipulators mainly include a plurality of sequentially connected and movable manipulators, each manipulator is movably connected and each manipulator can move freely. This kind of mechanical arm is installed on the rotating device that can rotate circumferentially through the main arm, and the main arm controls its own rotation and circumferential rotation through the control mechanis...

AI Technical Summary

Problems solved by technology

[0003] Existing manipulators mainly include a plurality of manipulators that are connected in sequence and can move. Each manipulator is movably connected and each manipulator can move freely. This kind of mechanical arm is installed on the rotating device that can rotate circumferentially through the main arm, and the main arm controls its own rotation and circumferential rotation through the control mechanism, which has the following technical problems. 1. The movable joints of the whole manipulator are less, causing the manipulator The range of motion of the robot is small, resulting in poor movement flexibility and low work efficiency of the manipulator; 2. The entire robot arm is large in size, and the structure of controlling each arm joint is relatively complicated, resulting in problems of high cost and high energy consumption. Larger, its movement is relatively slow, and it also has an impact on the working efficiency of the manipulator itself
