The welding positioner can ensure the smooth progress of the welding process when in use. It can play a good auxiliary role in welding and achieve good results in later use. An important accessory in the use of the positioner is the welding chuck. The application of the chuck can ensure the normal use of the welding machine, Therefore, in the later maintenance, we should not only pay attention to the maintenance of positioner, but also pay attention to the maintenance of chuck. Next, we will introduce it in detail.

1.卡盘使用完毕后，需要用气枪等工具清洗焊接变位机的焊接卡盘主体及滑道表面。由此，即使在长时间使用卡盘后也能确保良好的精度，因此卡盘的定期润滑作业很重要。

1. After the chuck is used, the main body and slide surface of the welding chuck of the welding positioner need to be cleaned with air gun and other tools. Therefore, good accuracy can be ensured even after using the chuck for a long time, so regular lubrication of the chuck is very important.

2.每天少打一次二硫化钼润滑脂(颜色为黑色)，将润滑脂打入到焊接卡盘的润滑脂喷嘴内，直到润滑脂从夹爪面或焊接卡盘内孔(内孔保护罩和连接螺母)溢出为止。

2. Apply molybdenum disulfide grease (black color) at least once a day and drive the grease into the grease nozzle of the welding chuck until the grease overflows from the clamping jaw surface or the inner hole of the welding chuck (inner hole protective cover and connecting nut).

3.防止卡盘内部生锈，夹持力下降，无法夹紧工件，因此使用有防锈效果的切削油，使用切削油可以防止卡盘内部生锈。

3. Prevent rust inside the chuck, reduce the clamping force and fail to clamp the workpiece. Therefore, use cutting oil with anti rust effect. The use of cutting oil can prevent rust inside the chuck.

4.作业结束后，需要用气枪等清扫焊接卡盘主体及滑道面。

4. After the operation, the main body and slide surface of the welding chuck shall be cleaned with an air gun.

5.卡盘少每6个月拆下清洗，保持卡盘爪的折弯面清洁，给予润滑，延长卡盘的寿命。

5. The chuck shall be removed and cleaned at least every 6 months to keep the bending surface of the chuck claw clean and lubricated to prolong the service life of the chuck.

6.检查各部分零件有无破裂和磨损，削去铸铁少每两个月完全清扫一次，有重大损伤时需要立即更换新品。

6. Check whether all parts are cracked and worn. Cut off the cast iron and completely clean it at least once every two months. If there is major damage, it is necessary to replace it with a new one immediately.

7.每个工件需要使用不同的夹持方式，使用它夹持不规则的工件会损坏焊接卡盘。

7. Each workpiece needs different clamping methods. Using it to clamp irregular workpieces will damage the welding chuck.

8.在卡盘压力不正常的情况下，如果以高压力夹住卡盘，卡盘的寿命会下降，因此发现卡盘的间隙过大的情况下，需要立即更换新的卡盘。

8. When the chuck pressure is abnormal, if the chuck is clamped with high pressure, the service life of the chuck will decrease. Therefore, if the chuck clearance is found to be too large, it is necessary to replace the chuck immediately.

以上就是焊接变位机的卡盘具体维护的措施，在实施维护时需要注意定期进行维护，防止出现影响整体质量的现象，在后期的维护中要确保卡盘的质量不受损害，这样才能保证良好的维护效果。

The above is the specific maintenance measures for the chuck of the welding positioner. During the maintenance, pay attention to regular maintenance to prevent the phenomenon affecting the overall quality. In the later maintenance, ensure that the quality of the chuck is not damaged, so as to ensure good maintenance effect.
