? flat bed CNC lathe machine feedback device

Flat bed CNC machine is a typical product of mechanical and electrical integration. It is an automatic equipment integrating machine tools, computer, motor and drag, dynamic control and detection.

The basic components of numerical control lathe include control medium, numerical control device, servo system, feedback device and lathe body. The feedback device of flat bed CNC machine is following:

1.Flat bed CNC lathe machine feedback device is closed loop (half closed loop )control system, is the test link of flat bed CNC lathe machine. The device can be included in the servo system. It consists of detecting element and the corresponding circuit. Its purpose is to detect the actual movement speed and displacement of flat bed CNC lathe machine axes, and the information feedback to the CNC device or servo drive, constitute a closed-loop control system. The installation of the detection device and the location of the detection signal feedback are determined by the structure of the numerical control system.

The system without measuring feedback device is called open loop system.

2.The advanced servo system USES the digital servo drive technology, the servo drive and the numerical control device commonly USES the bus to connect.

Feedback signal is connected with the servo drive, and through the bus sent to the CNC device in most cases. Only on a few occasions or using analog control servo drive, feedback device is directly and numerical control device to connect.

The servo motor internal pulse encoder, rotating transformer, induction synchronizer, speed measuring machine, grating and magnetic ruler are the common detection devices of flat bed CNC lathe machine.

Flat bed CNC machine measuring device and feedback element, usually installed on the workbench or screw, is equivalent to the dial of ordinary machine tool and human eye.

It converts the actual bit of the machine tool table into the electrical signal feedback to the CNC device, which can be used to compare the error signal of the CNC device and the instruction value to control the direction of the machine tool to eliminate the error.




? The principle of flat bed CNC lathe machine fault diagnosis

1.The concept of flat bed CNC machine fault and fault diagnosis.

1)Flat bed CNC machine failure: flat bed CNC lathe machine lost its original function whole or part.

2)Flat bed CNC machine fault diagnosis: Fault diagnosis is refers to under certain working conditions to find out the cause of equipment a dysfunctional or property, judge state of degradation of parts or components, predict the development trend of degradation, etc. Take effective measures to eliminate and avoid the negative impact of the failure. It is the general name of fault state detection, fault pattern recognition and fault degree prediction.

2.The principle of flat bed CNC machine fault diagnosis.

1)Out-In way: The methods of looking, listening, smelling, asking and touching are examined by introversion.

2)First mechanical, electrical: Mechanical fault is easier to observe, and the fault diagnosis of CNC system is more difficult.

3)Static after dynamic: The maintenance personnel should be quiet and then move, the machine tool failure should also be static first.

4)First public, then special: Solve the main contradiction first, then solve the local and secondary contradictions.

5)Simple then complex.

6)First general, then special: When troubleshooting a fault, consider the most common possible reasons, and then analyze the specific reasons that rarely occur.
