integrated transfer machine boot debugging method? integrated transfer machine is a kind of machine tool with high technical content. After the user buys an integrated transfer machine, whether the machine is started correctly and safely and debugging is a key step. Whether this step is correct or not largely determines whether the integrated transfer machine can play a normal economic efficiency and its own service life, which is a significant issue for both the manufacturer and the user factory of the integrated transfer machine. When the integrated transfer machine is powered on, debugging should be carried out according to the following steps.

1 Check the appearance before power on

Open the electric control box of the machine tool, check whether the relay, contactor, fuse, servo motor speed, control unit socket, spindle motor speed control unit socket, etc. are loose, if they are loose, they should be restored to normal state, the connector with the locking mechanism must be locked, the machine tool with the adapter box must check the socket on the adapter box, and whether the wiring is loose. If there is a locking mechanism, it must be locked. Open the CNC electrical box door, check all kinds of interface sockets, servo motor feedback line socket, spindle pulse generator socket, hand pulse generator socket, CRT socket, etc., if loose to reinsert, there must be a locking mechanism must be locked. According to the instructions to check the setting of the short circuit terminal on each printed circuit board, it must meet the state set by the machine tool manufacturer, if it is indeed wrong, it should be reset, in general, there is no need to reset, but the user must make the original record of the setting state of the short circuit terminal. Wiring quality Check Check all wiring terminals. Including strong and weak electrical parts in the assembly of the machine tool manufacturer's own wiring terminals and the wiring terminals of each motor power line, each terminal should be tightened with a screw until the screw can not be screwed, and the motor socket must be tightened. Solenoid valve inspection All solenoid valves should be pushed several times by hand to prevent the poor action caused by no power for a long time, such as abnormal, should make a record for the confirmation of repair or replacement after power. Limit switch check Check all limit switch action flexibility and firmness is firm, found poor action or fixed should be dealt with immediately. Check the buttons and switches on the operation panel. Check the wiring of all buttons, switches and indicators on the operation panel. If any error is found, handle it immediately. Check the socket and wiring on the CRT unit. The ground cable must be good. The ground cable for measuring the machine tool must be good. The ground resistance cannot be greater than 1 Ohm. Check the phase sequence of the input power supply with the phase sequence table to ensure that the phase sequence of the input power supply is absolutely consistent with the calibrated power supply phase sequence everywhere on the machine tool.

For devices with secondary connections, such as power transformers, the phase sequence of the secondary connections must be consistent. Make sure the phase sequence is absolutely correct everywhere. At this time, the power supply voltage should be measured and recorded.

2. Switch on the total voltage of the machine tool

Switch on the main power supply of the machine tool, check whether the steering of the CNC electric box, the cooling fan of the spindle motor, the cooling fan of the machine tool electrical box is correct, the oil sign indication of lubrication, hydraulic pressure, etc., and the machine tool lamp are normal, and whether the fuse is damaged. If there is any abnormality, the power should be cut off immediately for maintenance, and no abnormality can be continued. Measure the voltage of each part of the strong current, especially the primary voltage of the power transformer for CNC and servo units, and make a record. Observe whether there is oil leakage, especially the hydraulic cylinder and solenoid valve where the feed turret is shifted, stuck, the spindle is shifted, and the chuck is stuck. If there is oil leakage, power failure should be repaired or replaced immediately.

The 3CNC power box is powered on

Press the power button of CNC power supply, turn on the CNC power supply, and observe the CRT display until the normal screen appears. If an ALARM is displayed, locate the fault and rectify it. In this case, power off the device again. Turn on the CNC power supply, measure the voltage at all levels according to the position of the test terminal given on the relevant data, and adjust the deviation to the given value, and make a record. Put the status switch in the appropriate position, such as Japan FANUC system should be placed in MDI status, select to the parameters page. Check the parameters bit by bit, item by item, and the parameters should match the random parameter list. If inconsistent parameters are found, the meaning of each parameter should be understood before deciding whether to modify, such as the value of backlash compensation may be inconsistent with the parameter table, which can be modified at any time after actual processing. The status selector switch is placed in the JOG position, the point speed is placed on the lowest setting, and the point operation is carried out respectively in the positive and negative directions of each coordinate. At the same time, the over-range protection switch corresponding to the point direction is pushed by hand to verify the reliability of its protection effect. Then, the over-range test is carried out at a slow speed to verify the correctness of the installation of the over-range ram. Set the status switch to the zero position and complete the zero operation. No other operation can be performed until the action returned by the reference point is completed. Therefore, in this case, this operation should be performed first, and then the fourth operation. The status switch is placed in the JOG position or MDI position, and the manual shift test is carried out. After verification, the spindle speed regulation switch is placed in the lowest position, and the spindle positive and negative rotation test is carried out for each gear, to observe the operation of the spindle and the correctness of the speed display, and then gradually increase the speed to the highest speed to observe the stability of the spindle operation. The manual guide lubrication test is carried out to make the guide rail have good lubrication. Gradually change the fast shift overshoot switch and feed rate switch, and point the tool holder at will to observe the correctness of the speed change.

4MDI test

Measure the actual speed of the spindle put the lock switch on the machine tool in the on position, enter the instructions with manual data, carry out the spindle arbitrary shift, speed change test, measure the actual speed of the spindle, and observe the displayed value of the spindle speed, and adjust its error should be limited to 5%. The purpose of the tool selection test of the turret or the tool holder is to check the correctness of the tool holder or the forward, reverse and positioning accuracy. Function test according to the order of the situation is different, the function is different, can be tested according to the specific situation of each function. In order to prevent accidents, it is best to lock the machine first for testing, and then release the machine for testing. EDIT function test put the status selection switch in the EDIT position, and prepare a simple program by itself, including as many functional instructions and auxiliary function instructions as possible. The moving size is limited to the maximum stroke of the machine tool, and the program is added, deleted and modified at the same time. Automatic state test will lock the machine tool, use the program to carry out empty running test, verify the correctness of the program, and then release the machine tool, respectively the feed rate switch, fast overshoot switch, spindle speed overshoot switch for a variety of changes, so that the machine tool in a variety of changes in the above switches for full operation, after each overshoot switch placed at 100%. Make the machine fully run and observe whether the working condition of the whole machine is normal.
