Synchronous belt pulley driving structure, robot drive base and tabletop-level mechanical arm

Abstract

The invention provides a synchronous belt pulley driving structure, a robot drive base and a tabletop-level mechanical arm. By means of ingeniously arranging the space relationship of a stepping motor, a first synchronous belt pulley, a second synchronous belt pulley, a synchronous belt, an output shaft, an encoder code disk and an encoder reading head portion on a base plate, arranging the transmission structure of the stepping motor, the first synchronous belt pulley, the second synchronous belt pulley, the synchronous belt and the output shaft and adopting the structural arrangement of theencoder code disk and the encoder reading head portion which are used for reading the rotation quantity of the output shaft, the synchronous belt pulley driving structure has a relatively low integration level since the structure is simple and parts are not excessive, and since the rotation quantity of the output shaft can be read, the control precision is guaranteed; and in this way, the materialcost, the installation cost and the maintenance cost are lowered, and the service life of the driving structure is effectively prolonged.

Description

technical field [0001] The invention relates to the field of drive technology, in particular to a synchronous pulley drive structure, a robot drive base and a desktop-level mechanical arm. Background technique [0002] Some desktop-level or lightweight robots or mechanical arms often use DC motors with reducers as drive devices, and some desktop-level or lightweight robots use DC motors with synchronous pulleys as drive devices. Then, these solutions often use Unsatisfactory. On the one hand, there are usually complex structures in the case of ensuring driving accuracy, which requires a high degree of integration, resulting in poor stability, high cost, and difficult assembly and disassembly. On the other hand In general, if you want to simplify the structure, you usually sacrifice the control accuracy, so there is an urgent need for a driving structure with low cost, simple structure, relatively low structural integration, and good control accuracy.

[0002] Some desktop-level or lightweight robots or mechanical arms often use DC motors with reducers as drive devices, and some desktop-level or lightweight robots use DC motors with synchronous pulleys as drive devices. Unsatisfactory. On the one hand, there are usually complex structures under the condition of ensuring the driving accuracy, which requires a high degree of integration, resulting in poor stability, high cost, and difficult loading and unloading. On the other hand In general, if you want to simplify the structure, you usually sacrifice the control accuracy, so there is an urgent need for a driving structure with low cost, simple structure, relatively low structural integration, and good control accuracy.
