Introduction to laser cladding positioner:

Structural composition

-Rotating spindle box: usually equipped with a chuck, used to clamp the workpiece so that it can rotate around the axis, such as the common three jaw self centering chuck, which can achieve fast clamping and centering.

-Hydraulic tailstock: It can slide and lock on the base, and its extension and contraction are driven by hydraulic pressure to assist in supporting and fixing the workpiece, ensuring a constant pushing force during the melting process.

-Adjustable idler: Used as an auxiliary support for long workpieces, it can slide and lock on the base, and can be adjusted according to the diameter of the workpiece.

-Basic welding base: As the foundation of the entire equipment, it plays a role in supporting and fixing other components, ensuring the stability of the equipment.

-Control system: used to control the speed of the spindle motor, the action of the hydraulic tailstock, etc., to achieve precise operation and control of the positioner.

working principle

By adjusting the speed of the rotating spindle box through the control system, the workpiece rotates at an appropriate speed. At the same time, with the cooperation of the laser head of the laser cladding equipment, the laser beam can be evenly irradiated on the surface of the workpiece, achieving laser cladding processing on the circumference or other parts of the workpiece. The hydraulic tailstock and adjustable idler ensure the stability and coaxiality of the workpiece during rotation.

Main function

-Realize the melting of complex shaped workpieces: the workpiece can be adjusted to the appropriate position and angle, allowing the laser melting head to process different parts of the workpiece, suitable for various shapes of workpieces such as shafts and disks.

-Improve the quality and efficiency of laser cladding: Accurately control the rotation speed and position of the workpiece to ensure uniform thickness and high bonding strength of the laser cladding layer, while reducing manual operation errors and improving processing efficiency.

-Expanding the application scope of laser cladding: Used in conjunction with different types of laser cladding equipment to meet the needs of various industrial fields, such as aerospace, automotive manufacturing, mechanical processing, etc.

technical parameter

-Spindle speed: It is generally adjustable within the range of 0-100r/min, and the spindle speed of the displacement machine varies with different load capacities.

-Positioning accuracy: The positioning accuracy of the chuck is generally ± 5arcmin, and the positioning accuracy of the tailstock tip is ≤ 0.15mm/full length. The coaxiality between the spindle chuck and the tailstock tip is ≤ 0.15 within the full length range.

-Load bearing capacity: Depending on different models and designs, the load bearing capacity ranges from several hundred kilograms to tens of tons. For example, the spindle speed of a displacement machine below 1T can reach 100rpm, while above 1T it is generally 30rpm.

application area 

-Aerospace field: used for repairing and strengthening key components such as aircraft engine blades and turbine disks.

-In the field of automobile manufacturing, surface cladding can be applied to parts such as engine crankshafts and camshafts to improve their wear resistance and corrosion resistance.

-Energy field: applicable to the manufacturing and repair of energy equipment components such as turbine blades and gas turbine blades.

-In the field of mechanical processing: surface strengthening and repair of various shaft, gear and other mechanical parts to extend the service life of the parts.
