Desktop Automatic Screw Tightening Machines: A Complete Machine with No Mechanism to Design
A desktop automatic screw tightening machine integrates the positioning mechanism, tightening spindle, controller and monitoring software in one machine: the workpiece sits in a fixture on the table, the spindle tightens point by point at taught coordinates, and the result of every screw is recorded. It suits lines that have no robot arm or XY table yet, where the workpiece can sit on a table and most tightening points are on one plane.
The SR-XYZ-552 is a 3-axis Cartesian screw fastening robot in the Utrun-Tech SR series, with 500 × 500 × 200 mm XYZ travel and ±0.05 mm repeatability on each axis, driving closed-loop stepper motors over EtherCAT. Operation uses a touchscreen graphical interface with uCode programming; quality is secured by the exclusive Z-axis pressure and height detection that flags floating, missing and stripped screws in real time; and data is uploaded to MES over RJ-45 Ethernet. Optional tightening tools: Vanguard PRO-FUSE series or DAI-ICHI DENTSU AFC3000 MFT series.
If the line already has a robot arm or another positioning mechanism and only needs the tightening part, see tightening modules for automation; screw feeders and torque meters are under accessories.
