Summary of Common Faults And Maintenance of The Four Station Turret of The Spinning Machine At present, it is common for small and medium-sized spinning machines to use four station electric turrets. Thefour station turret can improve processing efficiency, achieve multi process automation, and enhance processing flexibility. The following are typical faults and corresponding maintenance suggestions for four station electric turrets: (1) Possible reasons for turret failure to start/change: -Motor phase loss and abnormal three-phase power supply; -Mechanical jamming inside the turret (such as bending or rusting of the sliding pin after collision); -The transmission disk is damaged or the Hall element is malfunctioning; -The control system has no output signal. Repair method: -Check the power supply voltage and phase sequence of the motor, and measure the winding resistance; -Disassemble the turret, check whether the sliding pin, worm gear, and worm wheel are corroded or deformed, clean and lubricate them; -Use a multimeter to detect the output signal of the Hall element. If there is no change, replace the transmitter; -Check if the system I/O port output is normal and confirm if the tool change signal is sent out. (2) Possible reasons for the lock failure of the turret: -The position of the transmission disk is offset, and the Hall element is not aligned with the magnetic steel; -The system anti lock time is set too short; -Mechanical locking mechanism failure (such as locating pin fracture, spring fatigue); -Poor meshing or foreign objects on the internal gear plate of the turret. Repair method: -Remove the top cover of theturret, adjust the position of the transmitter disk, and align the Hall element with the magnetic steel; -Modify system parameters and extend the anti lock time (recommended to be set to 1.2 seconds or more); -Check whether the positioning pin and spring are damaged, and replace them if necessary; -Clean the gear disc, refill with lubricating oil, and ensure good meshing. (3) Possible reasons for continuous operation of the knife holder or non-stop rotation of a certain tool position: -A certain knife position Hall element is damaged; -Signal line open circuit or poor contact; -The transmission disk is damaged or the circuit is short circuited; -System receiving circuit malfunction. Repair method: -Use a multimeter to detect the output signal of the Hall element for the tool position; -Check whether the signal line is broken or the plug is loose; -Replace the transmission disk or repair the circuit; -If the above is normal, consider replacing the system I/O board or motherboard. (4) Possible reasons for turret offside (overshoot) or improper rotation: -Rear positioning pin stuck or spring failure; -The position of the transmission disk is offset, causing the signal to advance or lag; -The mechanical clearance inside the turret is too large; -The tool is too heavy or the turret is too long, resulting in high inertia. Repair method: -Check and replace the rear positioning pin or spring; -Adjust the relative position between the transmitter and the magnet; -Check the clearance between the worm gear and worm, and replace it if necessary; -Avoid using overweight cutting tools and optimize the length of the turret. (5) Possible reasons for inaccurate tool holder accuracy/poor repeated positioning: -The turret is not locked or the locking force is insufficient; -Wear or impurities on the gear plate; -Deformation of the upper blade body or poor gear meshing; -Hall element position offset. Repair method: -Extend the locking time and check the locking current; -Dismantle and clean the gear disc, remove impurities, and re lubricate; -Replace deformed parts, such as gear discs and upper blade bodies; -Adjust the relative height and angle between the Hall element and the magnet. Repair suggestions and precautions -Be sure to cut off the power before maintenance to prevent personal injury or equipment damage caused by misoperation; -Mark the disassembly and assembly of disk components to prevent misalignment during reassembly; -Regular maintenance: clean the inside of the turret, lubricate the worm gear, check the motor carbon brush and Hall element; -It is recommended to spare a tool holder assembly and commonly used vulnerable parts (such as a transmitter, Hall element, and locating pin) to improve maintenance efficiency.
