For the welding positioner, we will continue to understand and understand it. One of them 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.
1. Slewing drive and tilt drive of welding positioner
In the welding positioner, its slewing drive and tilt drive, for these two, we should know, the specific is:
Slewing drive: It should be able to achieve stepless speed regulation and is reversible. Moreover, in the range of the speed of rotation, when it is subjected to the maximum load, if there is fluctuation. Then the range of 5% cannot be exceeded, otherwise there will be problems.
Tilt drive: The specific requirements are to be able to run smoothly, and when under heavy load, the welding positioner can not be shaken, and the whole machine can not be overturned. In addition, it should be provided with a limit device to control the tilt angle well.
2. Description and comparison of two driving methods of welding positioner
In the welding positioner, the rotary motion of the table is usually driven by a DC motor. However, for the stepless shifting table, when it is tilting, there are two driving modes. First, the motor is decelerated by the speed reducer, and then the gear is used to drive the table to tilt, or the spiral pair Tilt the workbench. The second is to tilt the table directly through the hydraulic cylinder.
For the former one, it is generally used on a small positioner. In addition, in general, the tilting speed of the table is constant. Moreover, in the control loop of the drive system, there should be other functions, so that the welding positioner can have a good use effect.
