Problems solved by technology

The current telescopic manipulators all use pneumatic or hydraulic cylinders as the telescopic mechanism, which not only takes up space, but also has poor flexibility. It is not very suitable for some jobs that do not require too much force but require a wide telescopic range.

Embodiment 1

[0023] Such as figure 1 , 2 . As shown in 3, an automatic mechanical arm includes an arm body, and the arm body includes sleeves that are socketed step by step. In this embodiment, it has a structure with three levels of sleeves. A first-level casing 1, a second-level casing 2, and a third-level casing 3. The casing is a casing with a rectangular cross section. The nesting structure of the casing is similar to the pull-type retractable antenna mechanism, the casing decreases step by step, and the last stage is the smallest, and the casing should be made of insulator material.

[0024] Magnets 5 along the length direction of the casing, such as permanent magnets, are respectively arranged on the inner walls of the left and right sides of each level of casing, and the different magnetic poles of the two magnets are arranged oppositely, so that a magnet 5 perpendicular to the length direction of the casing is formed between the left and right magnets. magnetic field. Conductor...

Abstract

The invention provides an automatic mechanical arm, belongs to the technical field of automated machines and solves the problem in the prior art. The automatic mechanical arm comprises an arm body. The automatic mechanical arm is characterized in that the arm body comprises sleeves in stepwise sleeved connection, a magnet along the length direction of the corresponding sleeve is arranged on the inner wall of each of the left side and the right side of each sleeve, an electric conductor along the length direction of the corresponding sleeve is arranged on the inner wall of each of the upper side and the lower side of each sleeve, a groove is formed in each electric conductor, an electroconductive slider extending outwards is fixedly arranged at the bottom of the electric conductor in the next-stage sleeve sleeving in the previous-stage sleeve and slidably matched in the groove of the electric conductor in the previous-stage sleeve, and each electric conductor is connected with a lead which is connected with a current controller. The automatic mechanical arm is electromagnetically driven and is compact in structure, flexible to control and wide in extension and contraction range.

Description

technical field [0001] The invention belongs to the technical field of automatic machines, and relates to a mechanical arm, in particular to an automatic mechanical arm. Background technique [0002] The robotic arm is the most widely used automatic mechanical device in the field of robotics. It can be seen in 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] A mechanical arm capable of telescopic movement is a common and important mechanical arm. The current telescopic manipulators all use pneumatic or hydraulic cylinders as the telescopic mechanism, which not only takes up space, but also has poor flexibility. It is not very suitable for some jobs that do not require too much forc...
