Noise reduction type aluminum pipe for robot arm

Abstract

The invention provides a noise reduction type aluminum pipe for a robot arm, and relates to the technical field of aluminum pipes. The noise reduction type aluminum pipe comprises an aluminum pipe body, the outer surface of the aluminum pipe body is fixedly sleeved with a damping layer, the inner surface of the aluminum pipe body is fixedly embedded with a buffer layer, and the outer surface of the damping layer is fixedly sleeved with a sound insulation layer; a circular groove is formed in the sound insulation layer, the outer surface of the sound insulation layer is fixedly sleeved with ananti-abrasion layer, a noise reduction layer is fixedly embedded in the inner surface of the buffer layer, a plurality of circular through holes are formed in the inner wall of the noise reduction layer, and a protective layer is fixedly embedded in the inner wall of the noise reduction layer. According to the noise reduction aluminum pipe, when the aluminum pipe body works to generate noise, vibration generated by the aluminum pipe body is reduced through arrangement of the damping layer and the buffer layer, so that noise of the aluminum pipe body is reduced, the noise is further absorbed through the arrangement of the noise reduction layer and the sound insulation layer, and therefore the purpose of eliminating the noise generated when the aluminum pipe body works is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum tubes, in particular to a noise-reducing aluminum tube for a robot arm. Background technique [0002] A manipulator is an automatic operating device that can imitate certain movement functions of the human hand and arm to grab, carry objects or operate tools according to a fixed program. The characteristic is that various expected operations can be completed through programming, and the structure and performance have the advantages of both human and robotic machines. Generally, the material used by manipulators is aluminum tubes. Aluminum tubes are a kind of non-ferrous metal tubes, which refer to pure aluminum. Or the aluminum alloy is extruded into a hollow metal tubular material along its entire longitudinal length, which may have one or more closed through holes, with uniform wall thickness and cross-section, delivered in a straight line or in a roll. Widely used in automobiles, ships, aeros...

Problems solved by technology

[0003] However, when the existing aluminum tubes are in use, the noise produced is relatively large, which is difficult to eliminate, and will also affect the health of the staff. Moreover, when the existing aluminum tubes are in use, their own antifreeze ability and strength are not high, and they are still difficult to eliminate. There are aluminum tubes exposed to the air for a long time, which will be damaged by oxidation
