The traveling positioner is a piece of equipment widely used in industrial production. It is mainly used to change the position and posture of workpieces to meet the needs of different processing techniques, such as welding, cutting, grinding, laser cladding, etc. Its unique "one end is fixed and the other is walking" structural design gives it significant advantages when processing large and long workpieces, and can effectively improve processing efficiency and quality.

Structural features

Fixed end:

- The fixed end usually consists of a solid base and a headstock mounted on it. The base is made of high-strength cast iron or welded steel structure, which has good stability and shock resistance, and can withstand the weight of the workpiece and various forces generated during the processing.

- The spindle box is equipped with high-precision slewing bearings and drive motors to achieve precise rotation of the workpiece. The accuracy and load-bearing capacity of the slewing bearing directly affect the rotation accuracy and stability of the workpiece. Generally, high-grade crossed roller bearings or four-point contact ball bearings are used. The drive motor mostly uses an AC servo motor, which is connected to the main shaft through a precision reducer, which can provide stable torque output and accurately control the rotation speed and angle.

Traveling end:

- The traveling end mainly includes traveling trolleys, guide rails and drive systems. The traveling trolley is connected to the main spindle box at the fixed end through a connecting shaft or other connecting parts to support the other end of the workpiece. The trolley is made of high-quality steel and undergoes strict processing and heat treatment processes to ensure its strength and rigidity.

- Guide rails are generally installed on the workshop floor, using high-precision linear guide rails or heavy-duty steel rails. Linear guide rails have the advantages of high movement accuracy and low friction, which can ensure the smooth and smooth movement of the traveling trolley; heavy-duty rails are suitable for carrying workpieces with larger weights and have higher load-bearing capacity and wear resistance.

- The traveling drive system is usually driven by a motor and drives the traveling trolley to move on the guide rail through transmission devices such as reducers, chains or racks and pinions. The motor also uses AC servo motor or variable frequency motor to achieve precise speed control and positioning. During the walking process, the position information is fed back in real time through the position sensor (such as an encoder or grating ruler) installed on the trolley, and the control system accurately adjusts the walking speed and position according to the preset program.

Wide processing range: Due to the structural design with one end fixed and one traveling, the traveling positioner can adapt to the processing needs of workpieces of different lengths and weights. Whether it is a small workpiece with short dimensions or a large workpiece with a length of tens of meters, it can be processed by adjusting the position of the traveling end and the rotation parameters of the fixed end.

High processing accuracy: Both the fixed end and the traveling end of the traveling positioner adopt high-precision transmission devices and positioning systems, which can achieve precise rotation and movement of the workpiece. With the advanced control system, the position and attitude of the workpiece can be controlled within a very small error range to meet the requirements of high-precision processing.

Improve production efficiency: Through the traveling positioner, the processing equipment can continuously process different parts of the workpiece, reducing the number of clamping times and adjustment time of the workpiece, and greatly improving production efficiency. At the same time, since automated control can be achieved, operators only need to perform simple parameter settings and monitoring, which reduces labor intensity and improves production stability and consistency.

Strong flexibility: The control system of the traveling positioner has good programming functions and expansibility, and can be flexibly programmed according to different processing technology requirements. Operators can set a variety of processing paths and parameters according to actual needs to process workpieces of different shapes and sizes, with strong adaptability and flexibility.

In short, as an important industrial processing auxiliary equipment, the traveling positioner plays an increasingly important role in modern manufacturing with its unique structural design, high-precision control performance and wide range of applications. It has made important contributions to improving product quality, reducing production costs, and promoting the automation and intelligent development of industrial production.
