Mechanical arm

Abstract

The invention discloses a mechanical arm. The mechanical arm comprises a mechanical arm body, track bases and tooth groove tracks, a fluted disc is installed at the bottom end of the mechanical arm body, a containing platform is installed at the bottom end of the fluted disc, a control module is installed in the middle of the surface of the containing platform, a driving motor is installed at one end of the control module, and a mechanical control switch is installed at one end of the driving motor; sliding blocks are installed on the two sides of the bottom end of the containing platform, the tooth groove tracks are installed on the inner sides of the sliding blocks, notches are formed in the inner walls of one sides of the tooth groove tracks, and the track bases are installed at the bottom ends of the tooth groove tracks. An object capturing instrument capable of capturing the target distance is arranged, the mechanical arm body and the tooth groove tracks are combined, the distance between the mechanical arm and an target object can be captured in real time in the moving process, the mechanical arm can accurately stop on the vertical line of the target object after calculation according to the distance, and the accuracy of the mechanical arm in a practical process is ensured.

Description

technical field [0001] The invention relates to the field of manipulators, in particular to a manipulator. Background technique [0002] The manipulator is the most widely used automatic mechanical device in the field of robot technology. It can be seen in the fields of industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and precisely locate a certain point in three-dimensional (or two-dimensional) space for operation. [0003] Industrial manipulators generally move back and forth through rails. However, when the existing sliding rails need to move, in order to reduce friction, the inner wall is coated with organic oil. Therefore, when moving to the target range, it is necessary to stop the motion at the bottom of the manipulator by braking. Inertia, and the braking method is generally a bra...

[0003] Industrial manipulators generally move back and forth through rails. However, when the existing sliding rails need to move, in order to reduce friction, the inner wall is coated with organic oil. Therefore, when moving to the target range, it is necessary to stop the motion at the bottom of the manipulator by braking. Inertia, and the braking method is generally a brake or mechanical lock structure, which will not only affect its stopping performance under long-term use, but the manipulator as a precision device will also form a certain loss under the action of inertia, thus losing the original performance of the manipulator. precision function
