    As a special welding auxiliary device, welding positioner plays an important role in modern industrial welding production. It can be used with welding robots and welding machines to form an automatic welding center, and can also be used for workpiece displacement during manual operation.

    Welding positioner has many obvious advantages. First of all, high precision is a major feature. It can turn the workpiece to the ideal welding position, improve the distance compensation between the welding torch and the welding seam, realize accurate welding and stabilize the welding quality. The welding positioner adopts RV reducer, and the repeatability accuracy can reach+0.1 mm. Secondly, the service life is long. The simple driving system reduces the risk of failure, and the production efficiency can be improved with the welding robot. Furthermore, the welding positioner and the welding robot can realize coordinated movement. The control system with coordinated control function is used for unified control, and there are two ways: asynchronous coordinated movement and synchronous coordinated movement. When moving synchronously and coordinately, the welding robot and welding positioner run at the same time, which can weld complex workpieces.

    The base of welding positioner is welded by thick profile and steel plate. After annealing, the quality and accuracy are reliable. Overturning is driven by servo motor, and the reducer adopts high-precision reducer with reliable precision and adjustable speed. In addition, welding positioner can also liberate labor. Through the follow-up control with the welding robot, the control system realizes unified control. The operator only needs to stand on the assembly station and hold the teaching device away from the welding range. The welding positioner can automatically drag the weldment to show the weld seam. The welding robot can realize automatic welding, so it is also called the welding assistant.

I, high precision and durability

1. High precision

    The welding positioner is excellent in accuracy. It adopts RV reducer, and the repetition accuracy can reach+0.1 mm. This high-precision reducer can accurately control the rotation degree of the turntable and realize stable rotation even under the condition of loading the workpiece. The special gear structure of RV reducer controls the backlash to the minimum and realizes the accurate and smooth action of the gear. Due to the use of high-rigidity parts, the strength of the reducer itself is improved, and a precision reducer with load resistance and impact resistance is achieved, which provides a strong guarantee for the high precision of the welding positioner.

2. High durability

    The simple driving system of welding positioner can effectively reduce the risk of failure. The positioner frame is welded by steel and steel plates, with reasonable design structure and good bending and twisting resistance. Its base is welded with thickened profiles and steel plates, and after annealing, its quality and accuracy are reliable. This structural design and material selection enable the welding positioner to withstand various complicated working environments and load conditions, and ensure its long-term and stable operation. In addition, the welding positioner is driven by servo motor, and the reducer is a high-precision reducer with reliable precision and adjustable speed. These characteristics further improve the durability and reliability of welding positioner.

II, the applicability and operational reliability

1. Strong applicability

    Welding positioner has strong applicability. Its main function is to flip the workpiece during welding, so as to obtain a good welding position, which can meet the requirements of quality and appearance of various welded parts. Welding positioner can play an important role in manual welding, semi-automatic welding and automatic welding. It can be used with different types of welding machines, which provides great convenience for various welding applications. Moreover, it can also be customized according to the requirements to meet the individual needs of different users. For example, different industries, such as automobile manufacturing, construction machinery, electronics industry, etc., have different specifications and functional requirements for welding positioner, which can be better adapted to specific production environment and welding tasks through customization. There are various types of welding positioner, including seat welding positioner, U-shaped welding positioner, horizontal welding positioner, L-shaped welding positioner, three-axis welding positioner, etc. Users can comprehensively compare various specifications, application scope, welding conditions, technical parameters, etc., and choose welding positioner parameters that match their own workpieces to meet different production needs.

2. Reliable operation

    The working reliability of welding positioner is extremely high. Its base is welded with thickened profiles and steel plates, and after annealing, its quality and accuracy are reliable. This structural design enables the positioner to bear a large load and ensure the stability under various working conditions. The worktable is fixed on the transmission shaft and rotates smoothly under rated load, which provides a stable operating platform for welding work. The quality and accuracy of the welding positioner are reliable, which is also reflected in the servo motor driving for turnover and the high-precision reducer for speed adjustment. This design can not only meet the speed requirements of different welding processes, but also ensure the accuracy and stability of the welding process. For example, in some industries that require high welding precision, such as automobile manufacturing and electronics industry, the high precision and reliability of welding positioner ensure the quality and consistency of products. At the same time, the reliability of welding positioner also reduces the probability of equipment failure, improves production efficiency and reduces maintenance cost.

III, adjustability and other characteristics

1. Strong adjustability

    The welding positioner is highly adjustable, and the turning is driven by servo motor, which has many advantages. Servo motor can provide accurate power output to ensure the accuracy and stability of overturning action. The reducer adopts a high-precision reducer with reliable precision and adjustable speed. Through the high-precision reducer, the turning speed and angle can be accurately controlled to meet the requirements of different welding processes.

    At the same time, the welding positioner can automatically adjust the angle of the roller bracket according to the diameter of the workpiece, which makes it adapt to the support and rotary drive of workpieces with different diameters. Whether it is a small workpiece or a large workpiece, we can find the appropriate support angle and rotation speed on the welding positioner, so as to realize efficient and accurate welding.

2. Other characteristics

    (1) The welding positioner is equipped with a conductive device to prevent welding current from passing through the transmission parts such as bearings and gears. This design can effectively protect the transmission parts of the equipment and prolong the service life of the equipment. The resistance of the conductive device shall not exceed 1mΩ, and its capacity shall meet the requirements of rated welding current, so as to ensure that the current can stably pass through the conductive device during welding without causing damage to other parts of the equipment.

    (2) The control part shall be provided with a linkage interface for automatic welding. This linkage interface can make the welding positioner and automatic welding equipment seamlessly connected, and improve the degree of welding automation. Through the linkage interface, the welding positioner can perform precise actions according to the instructions of automatic welding equipment, and realize efficient and accurate welding.

    (3) The structure of the workbench is convenient for clamping workpieces or installing fixtures. The workbench of the welding positioner is designed reasonably, and the annular positioning lines evenly distributed at intervals and T-shaped grooves are processed on it, which not only facilitates the workpiece centering, but also facilitates the installation of various positioning and clamping fixtures. This design makes the clamping of the workpiece faster and more convenient, and improves the work efficiency.

   （4）The linkage interface reserved for the positioner can be linked with the manipulator and welder to form a welding center. The reserved linkage interface of welding positioner can be linked with manipulator, welder and other equipment to form a complete welding center. In this welding center, all equipment can work together to achieve efficient and accurate welding. For example, when the welding robot is welding, the welding positioner can move synchronously according to the instruction, so that the welding seam of the space curve to be welded is placed in a position convenient for welding, and the welding quality and efficiency are improved.
