Automobile Electric Power Steering Device Sensor Welding Machine

Automobile electric power steering device sensor welding machine
The equipment is suitable for welding the sensor and shaft of electric power steering device. It is controlled by PLC, it’s convenient to transfer with the product model linked to the menu, the transfer time, the welding points and strength can be adjusted by changing the parameters, and the focal length can be adjusted for different diameters of the outer circle.
The equipment is divided into two stations and two welding guns are set up. One station is to weld the sensor rotor with the output shaft, while the other is to weld the sensor body with the input shaft. Drive mechanism is provided below the equipment, which is composed of servo motor and pneumatic chuck. It can precisely control rotation angle to ensure even welding spot and reliable strength. The welding process is protected by argon, which is harmless to the sensor plastic parts, the sensor performance and the plastic parts.

Main performance：
● Input angle：angle is unlimited, accuracy 0.036°
● Maximum laser output power：300W
● Maximum laser pulse energy：60J
● Cooling method：water cooling
● Closed loop feedback control：laser power feedback
● Spot welding, continuous welding, multi-point welding,
step welding can be programmed
● Welding camera monitoring, welding situation can be amplified display

Applications and benefits
● No need to achieve output automatic locking for the spline with the pneumatic chuck clamping device.
● The clamping device of prototype adopts a separate structure, which can meet the needs of testing different specifications of the prototype.
● The drive part adopts the coordination mode of motor and pneumatic chuck to save assembly space, short design cycle and high assembly precision.
● High degree of automation with the feed and disengage of cylinder drive clamp.
● The driving part of welding gun adopts the structure of motor and lead screw to realize complete automation of the whole process.
