ABB FSI1404-4 FSI series ball screws robots convert rotational linear motion

ABB brand FSI4010-4 ball screw, which belongs to ABBA ball screw FSI series, is widely used in robots. The following are its features and related applications:

Features

High precision: ABBA ball screws are usually produced continuously using Japanese-made machinery and equipment. In the processes of grinding, assembly, inspection, etc., the temperature and humidity of the factory environment are strictly controlled, and the perfect quality management system ensures its accuracy. FSI4010 - 4 can convert rotational motion into high-precision linear motion, with high positioning accuracy and repeatability, which can ensure that the robot can accurately complete various actions.

High efficiency: There are balls rolling between the screw shaft and the nut. Compared with the sliding screw pair, the driving torque can reach less than 1/3, and the same motion result can be achieved with less power, which can save electricity during the operation of the robot.

Precise micro-feeding: With ball motion, the starting torque is extremely small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro-feeding and meet the robot's requirements for fine movements. For example, when the robot assembles precision parts, it can accurately control the position of the end effector.

High rigidity: Both the lead screw and the ball nut are surface hardened to achieve a specific hardness and hardening layer depth, and the multi-thread design allows more balls to be loaded into the nut, enhancing rigidity. It can withstand large loads and frequent movements, and is suitable for the force requirements of the robot under different working conditions, such as when the robot arm is extended or grabbing heavy objects, it can ensure smooth movement and accuracy.

Low noise: The specially designed ball circulation tube (patent pending) allows the ball to circulate smoothly in the nut, and the ball circumference diameter (BCD) is accurate and consistent throughout the thread, the drag torque is stable, and the operating noise is low, which is conducive to creating a quiet working environment.

Dimensional parameters

The lead screw shaft diameter is 40mm, the lead is 10mm, the ball diameter is 6.35mm, the nut outer diameter is 104mm, the nut length is 93mm, the dynamic rated load is 5399kgf, and the static rated load is 10074kgf.

Application in robots

Robot joint drive: converts the rotational motion of the motor into the linear motion of the joint, and accurately controls the rotation angle and displacement of the lead screw to enable the robot joint to accurately reach the specified position, realize complex movements such as arm extension, bending and rotation, and help improve the motion accuracy and stability of the robot joint.

Robot end effector control: provides high-precision linear motion for end effectors such as grippers and welding guns, so that they can accurately grasp objects, perform welding operations or complete other delicate tasks, ensuring work quality and accuracy. For example, on the electronic product production line, the robot drives the gripper through the FSI4010-4 ball screw to accurately grasp tiny electronic components for assembly.

Robot mobile platform positioning: used to drive the linear motion of the robot platform that needs to move on the plane, cooperate with the motor and control system to achieve precise positioning and rapid movement of the platform in a two-dimensional plane, suitable for application scenarios such as logistics handling robots and inspection robots. For example, logistics handling robots rely on FSI4010-4 ball screws to accurately move to the designated shelf position in the warehouse to pick up or put goods.
