Design principle of adjustable welding rotator

Welding rotators are available in various forms, such as automatic welding rotator, adjustable welding rotator, flat welding rotator, tilting welding rotator, and anti-axial movement welding rotator. Used for welding, polishing, lining, and assembly of the cylindrical cylinder, a self-adjusting welding rotator can be adjusted according to the size of the cylinder. Adjustable welding rotator can be adjusted by screw and screw classification. To make the adjustable welding rotator play its super role, whether the design is reasonable will directly determine this point.

The design principle of adjustable welding Rotator is:

In addition to meeting the production needs, in the design process, in addition, to strictly comply with the relevant mechanical design standards, but also fully consider the rationality of design and economic factors, to design cost-effective welding rotator and other welding equipment.

Design of adjustable welding Rotator:

1. Each welding rotator consists of 1 active frame and 1 driven frame.

2. The active frame is composed of a base, roller supporting seat, roller, screw, drive motor reducer, control system, and other parts.

3. Driven frame is composed of a base, roller supporting seat, roller, screw, and other parts (excluding the driving part).

4. The base is located below the welding rotator to bear the weight of the workpiece and the welding Rotator itself, and transfer the weight to the workshop floor to meet the bearing capacity requirements of the workshop floor. The base is welded with high-quality steel plate and section steel, annealed after welding to eliminate welding stress, and then refined, with high strength, good rigidity, long-term use without deformation, and good shock absorption performance.

5. The roller support seat is arranged on the base, the base is installed with positive and negative buckle screw, the screw is fixed on the roller support seat, the lead screw is provided with two handwheels, can be adjusted by hand wheel two roller spacing, to adapt to the needs of different diameters of the workpiece processing.

6. The roller is used to support the workpiece and transfer torque, connected with the rotating shaft through the key connection, and installed in the swing frame part; The output torque of the motor is transmitted to the roller through the gear mechanism, and the workpiece is driven to rotate by the friction between the roller and the workpiece. The steel core is used to carry the weight of the workpiece, and the polyurethane part is used to increase the friction force, which can prevent the workpiece from slipping during rotation.

7. Use two sets of drive deceleration system synchronous drive, respectively by three-phase AC motor, cycloid reducer, and worm reducer combined. Not only embodies the high rate of deceleration system but also has a good self-locking bit function.

8. Welding rotator is equipped with a mechanical fixed wheel anti-channering device. When the cylinder workpiece is welded on the welding rotator, it can prevent the axial channering, and the axial channering momentum is ≤±3mm.

The center distance of each pair of rollers can be adjusted according to the diameter of the cylinder workpiece to ensure that the wrap Angle of the two rollers is 45° larger than 110°.

10. Electric control system is composed of electrical box and wired manual control box; Adopts frequency conversion without speed regulation, parameters can be a preset and digital display, speed regulation precision is high, easy to maintain the compliance of processing specifications. Wired (15m) manual control box for remote control, positive and negative rotation, speed regulation, start, stop action, simple and convenient operation. (The electrical system can also be combined with the welding manipulator for centralized control. The operation of the same manual control box is simple and convenient.)

11. With over-voltage protection, self-protection function, and fault display and storage function, automatic air switch short circuit protection, preset parameters.
