Description

Technical Field

[0001] The utility model relates to the field of industrial robots, in particular to a telescopic shaft of an industrial robot. Background Art

[0002] Industrial robots can perform various tasks according to pre-programmed procedures, replacing heavy human labor and achieving mechanization and automation in production. Industrial robots consist of a robotic arm and an end effector (e.g., a welding torch, a spray gun, or a clamp) mounted on the wrist at the front end of the robotic arm.

[0003] Chinese Patent No.: CN220389435U A telescopic shaft for an industrial robot includes a robot body, the robot body comprising a main chassis, a large arm rotatably mounted on the outer wall of the main chassis, and a small arm rotatably mounted at the free end of the large arm. The small arm is rotatably mounted with a support plate away from the free end of the large arm, and a telescopic shaft body is rotatably mounted on the outer wall of the support plate. The telescopic shaft body also has a telescopic positioning assembly on its periphery that can position itself during extension and retraction. The telescopic positioning assembly includes positioning rods symmetrically arranged on both sides of the telescopic shaft body and capable of retracting and retracting as the telescopic shaft body retracts and retracts. Each positioning rod is also provided with a removable end cap at one end. This industrial robot telescopic shaft can improve the telescopic stability of the telescopic shaft body, prevent the telescopic shaft body from tilting or even breaking due to the gravity of a heavy object during operation, and thus increase the service life of the telescopic shaft body.

[0004] However, industrial robots are usually used in factory production workshops. During the processing and use, dust and oil in the workshop can easily adhere to the surface of the telescopic shaft and the telescopic free shaft. If they are not cleaned in time, it will not only affect the normal extension and retraction of the telescopic free shaft, but also easily cause damage to the telescopic shaft and the telescopic free shaft over a long period of time.

[0005] Therefore, it is necessary to invent a telescopic shaft of an industrial robot. Utility Model Content
