Switching assembly of servo motor and speed reducer, switching device and rotation driving mechanism

Abstract

The embodiment of the invention relates to an adapter, in particular to an adapter assembly of a servo motor and a speed reducer, an adapter device and a rotary driving mechanism, the adapter assembly comprises an adapter shaft and an output gear, the adapter shaft comprises a first connecting part and a second connecting part connected with the first connecting part, and the first connecting part and the second connecting part are coaxially arranged; in the coaxial direction of the first connecting part and the second connecting part, a first shaft hole is formed in the end, away from the second connecting part, of the first connecting part, a second shaft hole is formed in the end, away from the first connecting part, of the second connecting part, and an output shaft of the servo motor is inserted into the first shaft hole; the output gear comprises a shaft body inserted into the second shaft hole and a gear body coaxially connected with the shaft body, the shaft body is detachably connected with the second connecting part, and the gear body is used for being meshed with a reduction gear of the speed reducer. Compared with the prior art, not only is the structure simple, but also the rotary driving mechanism is convenient to disassemble and assemble, and later repair and maintenance are convenient.

Description

technical field [0001] Embodiments of the present invention relate to an adapter, in particular to an adapter assembly, an adapter device and a rotary drive mechanism for a servo motor and a reducer. Background technique [0002] Positioner, as a device used to drag the workpiece to be welded and move the weld seam to the ideal position for welding operation, is often used in arc welding, laser welding and other applications, such as the field of automobile manufacturing. However, the inventors found that the rotary drive mechanism adopted by the current positioner is generally realized by a servo motor with a reducer. At the same time, in order to realize the power transmission from the servo motor to the reducer, it is generally necessary to install Set corresponding transfer components between them, but the structure of the transfer components is generally too complicated, and needs to be specially customized according to the size of the reduction gear of the reducer.

However, the inventors found that the rotary drive mechanism adopted by the current positioner is generally realized by a servo motor with a reducer. At the same time, in order to realize the power transmission from the servo motor to the reducer, it is generally necessary to install Set corresponding transfer components between them, but the structure of the transfer components is generally too complicated, and needs to be specially customized according to the size of the reduction gear of the reducer. Most of the components cannot be produced in a standardized manner. Upkeep and maintenance make a big difference
