A sealed mechanical arm joint structure

Abstract

The invention discloses a sealed mechanical arm joint structure, wherein a No. 1 sealing ring is arranged between the motor mounting plate and the flange, a No. 2 sealing ring is arranged between the flange and the connecting piece, and the flange and the shell There is a No. 3 sealing ring between the bodies, and a No. 4 sealing ring is set between the motor shield and the sealing shell; the motor shield is located inside the protective cover, one end of the protective cover is embedded in the sealing shell, and the other end of the protective cover is towards the One end of the motor shield extends and encloses the motor shield inside. In this application, the motor is protected inside the housing, and multiple sealing rings are used to seal the joints, so that the joint structure has good sealing performance and waterproof performance, and can be applied in the field and other occasions; Setting, the gap between the motor shield and the sealing shell is sealed and protected, which can effectively ensure the sealing performance and waterproof performance of the joint structure.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a sealed type mechanical arm joint structure. Background technique [0002] With the rapid development of automobiles, chemicals, electronics, food processing, plastics, life sciences and other fields, especially in the field of robotic equipment, the transmission accuracy, safety and reliability, and shock absorption of the mechanical arm drive joint structure of the robot Noise, light weight, maintenance-free and other performances put forward more stringent standards. The drive joint structure is one of the core components in the robot system, which is used to transform the high-speed, low-torque power at the power end into low-speed, high-torque power output. [0003] At present, most of the manipulators are usually used indoors, so the sealing performance of the driving joint structure is not high, but for places with high humidity, or in the field, the sealing perf...

Problems solved by technology

[0003] At present, most of the manipulators are usually used indoors, so the sealing performance of the driving joint structure is not high, but for places with high humidity, or in the field, the sealing performance and waterproof performance of the driving joint structure are particularly important. Important, because water vapor or moisture enters the interior of the drive joint structure along the gap, it will affect the service life of the internal electrical components, and then affect the normal operation of the robotic arm
