In modern industrial production, robots have been widely used, especially in the welding operations of many production lines, but only robots can not complete all welding operations, so they are generally equipped with a positioner turntable, making it the external movement axis of the robot. So what are the advantages of using a rotary table? How to judge the positioner when selecting?

It is a special auxiliary equipment to complete active welding, suitable for welding displacement in reverse operations to achieve the required processing orientation and welding speed, the specific advantages are as follows:

1. High accuracy: the repetitive accuracy of the reducer and welding positioner can reach 0.1 mm.

2. High durability: The simple drive system reduces the risk of failure.

3. Strong applicability: The primary function of the welding positioner is to flip and shift the workpiece during the welding process to obtain a good orientation and meet the quality and appearance requirements of various objects.

4. Reliable operation: the base of the rotary table of the positioner is welded with thickened profiles and steel plates. After annealing treatment, the quality and accuracy are reliable.

5. Strong adjustability: the use of servo motor to drive its turnover, the use of high-precision reducer as a reducer, there are many advantages, but these advantages are also based on the premise of its quality, if the quality is not reliable enough, not only can not meet the production capacity of the production line, and may even lead to a decline in production quality, so we must know how to judge the quality of the welding positioner.

6. Check the rollover drive.

(1) Oblique transmission should be stable, no load shaking, the whole machine does not overturn. If the load exceeds 25 kg, it should have a power drive function.

(2) There should be a limit device and Angle indicator for controlling the oblique Angle.

(3) The inclined arrangement should have a self-locking function and do not slide under load.

7. Check the rotary drive motor.

(1) The rotary drive motor should complete stepless speed regulation and braking.

(2) Within the speed range, the speed fluctuation under the load does not exceed 5%.

8. Other aspects

(1) The rotary table should be equipped with conductive equipment to prevent welding current from passing through bearings, gears and other transmission parts, and the resistance of the conductive equipment should not exceed 1m, and its capacity should meet the requirements of the rated welding current.

(2) Its control part should provide an active welding linkage interface.

(3) The structure of the operating platform should be easy to grip the workpiece or fixture, and its structure can also be negotiated with the user.

(4) The exact data of load, offset and weight should be clearly stated in its operating instructions.
