Electromechanical NC joining module NCFT, servo press for processes with low forces

2157B

The NC joining module NCFT Type 2157B with integrated piezoelectric force sensor for two predefined measuring ranges of 0,05 ... 1,5 kN is excellent for use in assembly and joining processes monitored by force displacement. Besides a straight version, a compact angular version is available.
 
  • High-precision force measurement via telemetry
  • Certified for ISO 14644-1 class 8 clean room use (7 possible)
  • Extremely wide measuring range of 0,05 … 1,5 kN
  • High velocity for very short cycle times
  • High overload capacity of sensor

The NC joining modules NCFT Type 2157B consist of a robust housing with an integral piezoelectric tension/compression force sensor.

An absolute encoder for precise positioning is integrated in the drive motor. The compressive or tension forces affecting the sensor create a proportional electrical charge in the piezoelectric measuring element, which is converted into an analog voltage signal by an integrated charge amplifier. The force sensor is installed directly in the tool connector for maximum precision of the force measurement. Signals are transmitted by telemetry. This means that no additional connection cables are required. The motor of the NC joining module is an electronically commutated AC servo type controlled by a servo electronics to ensure constant rotational and therefore translational speed. Standard functions like block pressing, position pressing and force feedback controlled pressing, as well as intermediate positioning, are supported. Besides a straight version with 100 mm stroke, a compact angular version with 250 mm stroke is available. The NC joining module NCFT can be operated with the IndraDrive servo amplifier in combination with maXYmos NC Type 5847. The communication between IndraDrive and maXYmos NC takes place in real-time via SERCOS III. Several field bus slave interfaces are available onboard for customer controlling. PROFIBUS, PROFINET, EtherNet/IP or even EtherCAT can be used with the maXYmos NC at the customer's choosing. Quality data can be transmitted via the Ethernet interface through different protocols and a visualization via VNC or a data backup can be performed.
