Servo Carrier Shaft Debugging

Term：

  • Carrier mechanism： On the tube cutting machine, the mechanical structure supporting the tube.
  • Servo carrier： A carrier mechanism that uses a servo motor to dynamically adjust the highest point position of the carrier mechanism.
  • Bed roller carrier： The carrier mechanism is at the feeding side.
  • Blanking roller carrier： The carrier mechanism is at the blanking side.

Function of Servo Carrier：

When machining long and thin tubes, when the chuck rotates, the tubes will sag, deform and shake, which will affect the machining safety and machining accuracy. The servo carrier mechanism can solve the problem well. The principle is that the highest point of the carrier mechanism is always just in contact with the lowest point of the pipe when the chuck is rotating or when the chuck is stationary.

This section takes the bed roller carrier as an example to introduce the debugging methods and steps of the servo carrier.

Operating Premise：

  • Chuck debugging has been completed.
  • The feeding shaft and servo carrier shaft are debugged and can move normally.
  • The servo carrier shaft has finished returning to the mechanical zero point, or the reference has been set.
  • The support cylinder can work normally.

Operating Steps：

  1. Adjust the movement direction of the Servo Carrier Shaft to ensure that when the Servo Carrier Shaft moves in the positive direction, the Carrier Highest Point rises and the reverse movement decreases.

    1. In the menu bar, click Set → to open the System Parameter dialog box.
    2. In the node tree, click the Show All → Basic Param → 1.0 Axis Param node.

  2. Set the positive and negative soft limits of Servo Carrier Shaft to ensure that the position of Carrier Highest Point will change when Servo Carrier Shaft moves.

    The purpose of this step is to ensure that when the Support Cylinder is supported, the Carrier Highest Point position is completely adjusted by the Servo Carrier Shaft.

    1. In the node tree, click the Show All → Basic Param → 1.0 Axis Param node.
    2. In the 1.0 Axis Param parameter column, adjust the positive and negative soft limit of Servo Carrier Shaft, and enable the soft limit protection.

  3. When the Servo Carrier Shaft moves in a 5mm step, record several groups of Carrier Highest Point height values.

    1. In the menu bar, click Maintain → to open the Servo Roller Debug dialog box：

    2. In the Locate area, click the + button to make the W axis (servo carrier shaft) move near the upper limit of its soft limit, and the Carrier Highest Point is at the highest position.

    3. Record the value of Carrier Highest Point at the highest position.

    4. Check Step, switch to step mode, and set the step size to 5.

    5. Click the - button and record the corresponding Carrier Highest Point until the W axis (servo carrier shaft) moves to the lower limit of its soft limit.

    For example： The following table shows the debugging data of a customer.

    W3 Axis Step Size Carrier Highest Point Change of Carrier Highest Point
    5 172.5 -
    5 169.1 3.4
    5 164.8 4.3
    5 160.7 4.1
    5 156.4 4.3
    5 164.8 4.3
    5 160.7 4.1
    5 156.4 4.3
    5 152.1 4.3
    5 147.8 4.3
    5 143.6 4.2

  4. Calculate the average value of carrier highest point change.

    For example, in the above table, when the W3 axis (servo carrier shaft) step is 5mm, the average change of Carrier Highest Point is (4.3+4.1+4.3+4.3+4.2)/6=4.25. Note, that discrete data records must be discarded in this step, such as 3.4 in the table above.

  5. Calculate the ratio between the average change value of Carrier Highest Point and the movement step size of Servo Carrier Shaft.

    For example, in the above table： K = 4.25 / 5 = 0.85

  6. Adjust the Servo Carrier Shaft pitch according to the ratio between the average value of Carrier Highest Point change and the Servo Carrier Shaft motion step.

    New Servo Carrier Shaft pitch=original Servo Carrier Shaft pitch * K

    According to the above calculation, the screw pitch is adjusted from 10 to 8.5.

  7. Perform Servo Carrier Shaft calibration or homing, and reset the upper and lower limit values of the Servo Carrier Shaft soft limit.

    Note

    This step is because the screw pitch of Servo Carrier Shaft has been adjusted.

  8. Repeat step 3 (step 4, step 5, step 6 and step 7 will not be executed), and verify whether the Servo Carrier Shaft moves 1mm and the Carrier Highest Point height changes 1mm after adjusting the Servo Carrier Shaft pitch.

    For example： The following is the data of a customer's machine tool after adjusting the Servo Carrier Shaft pitch.

    W3 Axis Step Size Carrier Highest Point Change of Carrier Highest Point
    5 172.5 -
    5 167.8 4.8
    5 162.7 5.1
    5 160.7 4.1
    5 157.4 5
    5 152.9 4.8
Note

Description： If the Servo Carrier Shaft pitch is adjusted, the Servo Carrier Shaft moves for 1mm, and the height change of the Carrier Highest Point differs greatly from 1mm, step 3 must be repeated (step 4, step 5, step 6 and step 7 must be performed at the same time).

  3. Click Save to finish debugging.

    Caution

    In consideration of pipe sagging, it is recommended that the carrier highest point close to the chuck should be 1~3mm away from the lower surface of the tube during calibration to avoid the carrier from pressing the tube out of the indentation during normal machining after commissioning.
