As for the welding positioner, we will continue to understand and understand it below. This is what everyone wants to see. As for its specific content, it is divided into two parts, one is its rotary drive and tilt drive, and the other is the description and comparison of the two drive modes of the welding positioner. Its explanation is as follows.

1. Rotary drive and tilt drive of welding positioner

In the welding positioner, its rotary drive and tilt drive, for these two, we should know that the specifics are:

Slewing drive: It should be able to achieve step-less speed regulation and is reversible. Moreover, in the range of slewing speed, when it bears the maximum load if there are fluctuations. Then the specified range of 5% must not be exceeded; otherwise, problems will occur.

Tilt drive: The specific requirements are to be able to proceed smoothly, and when under heavy load, the welding positioner must not shake, and the whole machine cannot be overturned. In addition, it should be equipped with a limited device to control the tilt angle.

2. Explanation and comparison of two driving methods of welding positioner

In the welding positioner, the rotary motion of the worktable is usually driven by a DC motor. However, for a continuously variable table, when it is tilted, there are two driving methods. First, the engine is decelerated by the reducer, and then the table is tilted by the gear, or by the screw Tilt the table. Second, the worktable is tilted directly through the hydraulic cylinder.

For the former, it is generally used on small positioners. In addition, generally speaking, the tilting speed of the table is constant. And, in the control loop of the drive system, it should also have some other functions, so that the welding positioner can have a good use effect.
