Abstract

The invention provides a mechanical arm based on a concentricity principle. The mechanical arm based on the concentricity principle comprises a linear opening hollow optical shaft with an opening formed in the front side, the left end of the outer side of the linear opening hollow optical shaft is rotationally provided with a left driven wheel base and a left driving wheel base rotationally installed on the left driven wheel base in a sliding mode, the right end of the outer side of the linear opening hollow optical shaft is rotationally provided with a right driven wheel base and a right driving wheel base rotationally installed on the right driven wheel base in a sliding mode, and the linear opening hollow optical shaft is located at a connecting center point of the left driven wheel base, the left driving wheel base, the right driven wheel base and the right driving wheel base. According to the mechanical arm based on the concentricity principle, by means of concentricity separation, curve changes on a massage chair track can be accurately fed back, the mechanical arm can more accurately massage a set part of a human body, and therefore, the mechanical arm is more attached to the human body compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a mechanical arm based on the principle of concentricity. Background technique [0002] The traditional massage robot arm uses an eccentric wheel to adjust the arc of the massage ball, which can only operate on a fixed arc, and cannot stretch the massage head horizontally inward or outward. The parts are different and cannot be adjusted. The strength of the massage ball cannot be adjusted. When the unstressed parts of the human body are massaged with the same strength, it will cause pain and reduce the comfort of the massage. In order to solve the above defects, we have proposed a mechanical arm based on the principle of concentricity. Contents of the invention [0003] The invention proposes a mechanical arm based on the principle of concentricity, which solves the problem that the traditional mechanical arm can only operate on a fixed arc and cannot stretch the massa...
