50000Nm torque calibration machine 0.1% accuracy dead weight loading lever type

 

The torque calibration machine is mainly used for the verification and calibration of torque transducers of various accuracy classes. The machine is controlled by PLC and software, and the measurement data can be calculated, processed, printed and recorded automatically.

This machine is mainly composed of lever system, weight loading system, torque balancing device, electrical control system and software.


Lever system

  • The lever adopts the structure of two-level lever, and the amplification ratio of the two-level lever is 1:10. The lever is connected with the detected part, and the attached weight loads the detected part to achieve the purpose of loading torque.
  • The lever system is a key part of the whole machine. The accuracy of its moment arm value directly affects the measurement accuracy of torque value. The bearing friction also affects the accuracy of the torque value. It has a direct effect on the uncertainty of the whole machine.
  • The lever must be level and balanced during the test.
  • The static equilibrium point of the lever can be adjusted by three balancing hammers in three coordinate directions.
  • By adjusting the balance hammer, the center of gravity of the whole lever system can be exactly coincident with the blade of the lever center. In this way, a very small load can be added in real time, and the lever can also react. The sensitivity of the lever can be very high.
  • The support is made of alloy steel with high strength, hardness and toughness. With the structure of balance blade and bearing, the contact between blade and bearing can be basically linear, so that the friction can be very small.
  • In the process of loading, the lever must be locked in the horizontal position to ensure that the torque value of each point changes smoothly during loading.
  • In the process of clamping the work piece, the lever remains unchanged at the horizontal balance position.
  • The locking device is located at one end of the lever, which is driven by a motor to rotate a bidirectional screw rod to make the two collet heads move in relative direction to achieve the purpose of clamping and releasing one end of the lever.
  • Lever in the process of clamping the workpiece, the lever should remain unchanged in the horizontal balance position. One is to play a role in protecting the lever support, to avoid damage to the knife edge when clamping. Second, when the weights are exchanged, the phenomenon of return trip can be avoided and the measurement can be more accurate.
  • The axial locking device is located in the middle section of the lever. The motor passes through the planetary gear, and then through the two-way screw rod, so that the two pairs of collet clamps the lever on the two axial end faces of the lever and the two sides of the center of the lever at the same time.
  • When the lever is loaded, it will lose its level during inspection. The leveling device is a structure that resets the lever back to the level. The device is installed on the sliding block of the linear guide rail on the bed, which is mainly composed of servo motor, reducer, ball screw loading arm and moving guide rail.

Dead weight loading system

  • Weights are used to generate static moments
  • Different moment values are obtained by loading different amounts of weights.
  • The weights are composed of two independent serial weights, the positive and the negative, which are loaded step by step to make the loading force more accurate and stable.
  • The weights are 50N/10 and 500N/10 respectively. The transmission system is under a set of moving beams, with simple structure and convenient maintenance.
  • Working principle of weight loading system:
  • The lifting motor is driven by reducer and toothed belt to drive the lifting ball screw, so that the weight pallet is lowered and the weight is hoisted on the lever step by step.
  • The position of the weight is determined by calculating the digital output of the draw-out wire encoder to the instrument. When the weight tray is lifted or lowered, the photoelectric encoder is measured, and the dividing value of the photoelectric encoder is up to 2500 lines/rotations. This can ensure the accuracy and reliability of weight position.

Moment balancer

  • Composition of torque balancing device: ac servo motor, servo controller, worm gear reducer, etc.
  • The working principle of torque balancing device: after the torque balance receives the signal of the eddy current displacement sensor of the lever system from the measurement and control system, the ac servo motor is controlled to run, and the workpiece is rotated in the opposite direction of deflection through the transmission of the reducer to keep the lever in the horizontal balance position. The transmission adopts worm reducer and synchronous gear belt to ensure the accuracy and reliability of transmission, low noise and smooth operation.
