Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0034] In this article, "first", "second", etc. are only used to distinguish each other, not to indicate the degree of importance and order, or the prerequisite for mutual existence.

[0035] Herein, "equal", "identical" and the like are not strictly restricted in the sense of mathematics and / or geometry, but also include errors understandable by those skilled in the art and allowed in manufacture or use. Unless otherwise stated, a numerical range herein includes not only the entire range within its two endpoints, but also several subranges subsumed therein.

[0036] In order to solve the problem in the prior art that the axial size of the joint is large due to the series arrangement of the internal parts of the joint, the present invention provides a m...

Abstract

The invention discloses a mechanical arm joint. The mechanical arm joint comprises a motor end input and brake part, a motor driving part, a decelerator part and a joint output part which are sequentially arranged in the axial direction of a motor of the joint. The motor end input and brake part comprises a motor end brake, a motor end coder and a first shell, wherein the motor end brake is located on one side of the input end of a split type hollow torque motor and arranged on a hollow shaft of the motor in a sleeving mode, the motor end brake is sleeved with the motor end coder, and the first shell contains the motor end brake and the motor end coder. A connector is connected with the motor end brake and the motor end coder together respectively.

Description

technical field [0001] The invention relates to the field of robot production, in particular to a mechanical arm and a mechanical arm joint. Background technique [0002] Since robots entered the field of industrial applications in the 1970s, the application of robots has greatly improved production quality and production efficiency. The main disadvantages of traditional industrial robots are: large volume, huge quality, etc., resulting in relatively low load weight, and at the same time pose a threat to the safety of operators, so they need to be isolated and work independently. [0003] With the expansion and improvement of robot application requirements, in the past 10 years, the advantages of light and small articulated robots have derived collaborative robots with higher operating efficiency, modular articulated robots, etc. Smaller, so it can have a higher load-to-weight ratio, and at the same time, it is easy to use for human-machine cooperation. [0004] In the exi...
