Actuators for robotic spot welding
- September 23, 2020
Available in two models, they are designed for automotive body-in-white resistance spot welding as well as high-production sheet-metal welding applications.
The compact servo motor and high-force actuator combo can deliver up to 30 million welds (CSWX model) in typical robotic welding applications along with increased force and speed capabilities.
The CSWX model was designed for steel and aluminum weld applications and features a specially-designed roller nut to handle welding applications with C, X and pinch weld guns. It provides up to 18 kN of pressing force (4,047 lbf) in a 90 mm frame. Top-speed C-gun performance is 10.5kN of force (2,023 lbf) and 700 mm/sec (27.5 in/sec). Options include integrated force feedback, manual override and long stroke.
The CSW model is handles lower force (15.6kN [3500lbf]) and lower duty cycle applications (20 million+ welds) for C, X and pinch weld guns. Top speed C-gun performance is 7.9kN (1,641 lbf) and 700 mm/sec (27.5 in/sec).
Both models include mid-trunion mounting to easily adapt to a variety of mounting locations, four standard stroke lengths, and force repeatability of plus or minus three per cent for the life of the actuator. Integrated anti-rotate and water-cooling options are available.
