L type welding positioner

L-type welding positioner, also known as welding turntable. Positioner is an indispensable equipment in the manufacturing industry, categorized as one of three welding auxiliary machines in the welding field. It together with the welding manipulator and turning roller, has been widely used in the machinery industry, with hundreds of varieties in model and scale.

Generally speaking, the welding positioner is used to assist in turning workpiece to a required position for easier operation. In other words, the workpiece is clamped on a device for welding by a positioner, and the initial position to be welded can be in any direction of the space. After weldment, the welding seam in any direction could become fillet weld or flat weld. In order to ensure the welding quality, vertical welding and bottom welding must be carried out, so the application of weding positioner improves the welding productivity and safety in the production process.

Welding positioner is a general and efficient welding equipment as prior choice by fabrication companes to realize circumferential seam welding. It can be equipped with welding power supplies such as argon arc welding machine, gas shielded welding machine and plasma welding machine, and set synchronized operation with other machines to form an automatic welding system.

L-type welding positioner is one of models of welding positioner. It is mainly composed of rotating head, displacement mechanism and controller. The rotation speed of the rotating head is adjustable, with an independent speed regulating circuit, the inclination angle can be adjusted as needed, and then the welding gun can move up and down with the air.

As shown on the figure below, the rotary table of L-type positioner is installed at one end of the extension arm. The extension arm generally rotates at an angle relative to a tilt axis. Therefore, the position of the tilt axis is mostly fixed, but some can tilt up and down within the range of less than 100 degrees. The displacement range of the machine is large, but the overall stability is worse than that of the positioner turntable. Therefore, the scope of application is to transform position of small and medium-sized workpieces below 1 ton. Among them, it is widely used in the manual welding, mostly driven by motor, and the bearing capacity is less than 500kg.

Product advantages

1. The intelligent control system realizes coordinated movement with the welding robot, with high flexibility;

2. It has a large open space and a variety of changing positions;

3. Replace workers to complete welding work in harsh environments;

4. Define the production cycle of the product;

5. Good welding stability within the rated load range;

6. Effectively reduce the deformation of weldments;

7. Improve welding efficiency;

8. It is suitable for welding auxiliary operation of batch products.

Application field

The combination of the welding positioner and the welding robot arm can realize the mechanization and automation of welding, and improve the welding efficiency and welding quality. The welding positioner can be used in automatic welding systems in the chemical industry, boilers, pressure vessels, motors, electrical appliances, railway transportation, metallurgy, and other industrial sectors.
