冲压机械手的动力源一般为交流伺服电机,因为由脉冲信号驱动,其伺服电机本身就可以实现调速,但是为什么冲压机械手还需要减速器呢?冲压机械手通常执行重复的动作,以完成相同的工序;为保证机械手在生产中能够可靠地完成工序任务,并确保工艺质量,对冲压机械手的定位精度和重复定位精度要求很高。因此,提高和确保机械手的精度就需要采用RV减速器或谐波减速器。
The power source of the stamping robot is generally AC servo motor, because driven by the pulse signal, its servo motor itself can achieve speed control, but why does the stamping robot need a decelerator? The stamping robot usually performs repeated actions to complete the same process; And ensure the quality of the process, the positioning accuracy of the stamping robot and repeated positioning accuracy requirements are very high. Therefore, the use of an RV reducer or harmonic decelerator is required to improve and ensure the accuracy of the robot.
精密减速器在冲压机械手中的另一作用是传递更大的扭矩。当负载较大时,一味提高伺服电机的功率是很不划算的,可以在适宜的速度范围内通过减速器来提高输出扭矩。此外,伺服电机在低频运转下容易发热和出现低频振动,对于长时间和周期性工作的冲压机械手这都不利于确保其精确、可靠地运行。
Another function of the precision reducer in the pressing machine is to deliver more torque. When the load is large, it is not cost-effective to increase the power of the servo motor, which can be increased by the reducer within the appropriate speed range. In addition, servo motors are prone to heat and low-frequency vibrations at low frequencies, which is not conducive to ensuring accurate and reliable operation for long-term and periodic pressmen.
