CNC lathe manufacturers in place after the knife can not be properly locked
Knife selection knife is normal, is normal, that is not reverse locking. Indicating the normal worm drive, the initial electrical circuit as the problem. In the machine tool holder control electrical schematic diagram, found in reverse locking tool in place signal is issued by a position switch to control, is not the switch that the surrounding lines there is a problem? In order to confirm the cause of this failure, open the top and side cover of the knife rest, use the multimeter to check the circuit diagram to check the line, found that the line is not open and short circuit, by hand press the turret reverse locking position switch, observe the ladder display Signal input, thus eliminating the electrical circuit problems. It may be inferred that the movement of the stopper is not in place, and the position of the micro switch is not actuated.
Then re-tooling once to observe, the results showed that: really did not move the dog in place. Then tighten the stopper bolts, try a normal tool change. And then a knife, the original fault has emerged, and found the shaft end of the shaft slip and climb phenomenon. Is it caused by the motor reverse locking position switch block is not in place, so the axle sleeve axial positioning treatment, the knife top cover installed. The result is a normal tool lock.
In general, for any failure, first according to the phenomenon, according to the principle to determine the point of failure, the analysis of each possibility, such as a switch, a line connector, a screw will be the cause of the malfunction, refer to the previous operation, maintenance history Analysis, can help narrow the search range, help to improve the efficiency of maintenance.
