Common faults and handling methods of the seventh axis of robots

With the widespread application of the seventh axis of robots, the daily maintenance and upkeep methods of the seventh axis are increasingly valued. No matter which type of machine, it requires proper maintenance and upkeep to maximize its value. Below is a brief description of the common faults and corresponding handling methods of the seventh axis of the Kubik robot in daily operations from two aspects of technology:

Troubleshooting:
Fault 1: The working indicator light of the seventh axis driver is normal, but the angle of operation varies greatly; Reason: The machine tool carriage has been running at high speed for a long time, and the repeated positioning accuracy of the tool holder has deviated during long-term use.
Fault 2: The drag plate can accurately return to the processing starting point every time, but the scale of the processed workpiece still changes. Reason: Generally caused by the spindle, the high-speed rolling of the spindle causes severe bearing wear, resulting in changes in the machining scale.
The solutions to the above two types of faults: use a dial gauge to lean against the bottom of the tool holder, and then perform a fixed cycle program through system correction. Check the repeated positioning accuracy of the drag plate, adjust the clearance of the screw rod, and replace the bearing. Use a dial gauge to check the repeated positioning accuracy of the tool holder, adjust the machinery or replace the tool holder.
Accurate maintenance of rotation scale:
The seventh axis rotation scale of the robot is precise, and the surface finish is poor.
The cause of the malfunction: It may be that the tool tip is damaged and not sharp. It is also possible that the seventh axis resonates and is placed unevenly, resulting in slight deviations in the processing technology.
Solution: Remove the parts of the tool that are not sharp after wear or damage, and select a better tool to align from scratch. When resonance occurs or placement is unstable, it is necessary to adjust the level and fix it steadily.
