1. Check the flip drive of the positioner
(1) The tilt drive should be stable, without shaking under load, and the whole machine should not overturn. If the load Q exceeds 25kg, it shall have the power driving function.
(2) There should be a limit device to control the inclination angle, and there should be an angle indicator.
(3) The tilting mechanism must have a self-locking function, which does not slide under load, and is safe and reliable.
2. Check the rotation drive motor of the positioner
(1) The rotating drive motor should realize stepless speed regulation and brake.
(2) Within the range of rotation speed, the fluctuation of the rotation speed when under load does not exceed 5%.
3. Other matters needing attention
(1) The positioner should be equipped with a conductive device to prevent welding current from passing through transmission parts such as bearings and gears. The resistance of the conductive device should not exceed 1mΩ, and its capacity should meet the requirements of the welding rated current.
(2) The control part of the positioner should be provided with a linkage interface for automatic welding.
(3) The structure of the workbench should be convenient for the installation of workpieces or fixtures, and its structure can also be determined through negotiation.
(4) The accurate data of load, eccentricity and center of gravity should be clearly stated in the manual of the positioner
