The following is an introduction to the laser cladding positioner:

Structural composition

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

- Hydraulic tail jack: It can be slid, positioned and locked on the base. Its expansion and contraction are hydraulically driven to assist in supporting and fixing the workpiece to ensure constant ejection force during the cladding process.

- Adjustable roller: used as auxiliary support for long workpieces. It can slide on the base and be locked and fixed, and can be adjusted according to the diameter of the workpiece.

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

- Control system: used to control the rotation speed of the spindle motor, the movement of the hydraulic tail jack, etc., to achieve precise operation and control of the positioner.

 

Working principle

The control system adjusts the rotation speed of the rotating spindle box so that the workpiece rotates at an appropriate speed. At the same time, it cooperates with the laser head of the laser cladding equipment so that the laser beam can be uniformly irradiated on the surface of the workpiece to achieve laser cladding processing of the circumference or other parts of the workpiece. The hydraulic tail top and adjustable rollers ensure the stability and coaxiality of the workpiece during rotation.

 

Main function

- Realize the cladding of complex-shaped workpieces: The workpiece can be adjusted to the appropriate position and angle, so that the laser cladding head can process different parts of the workpiece. It is suitable for workpieces of various shapes such as shafts and discs.

- Improve cladding quality and efficiency: Precisely control the rotation speed and position of the workpiece to ensure uniform thickness and high bonding strength of the laser cladding layer. It can also reduce manual operation errors and improve processing efficiency.

- Expand 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, automobile manufacturing, mechanical processing, etc.

 

Technical parameters

- Spindle speed: Generally adjustable within the range of 0-100r/min. The spindle speed of positioners with different load-bearing capacities is different.

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

- Bearing capacity: Depending on the model and design, the bearing capacity ranges from hundreds of kilograms to tens of tons. For example, the spindle speed of a positioner below 1T can reach 100rpm, and above 1T it is generally 30rpm.

 

Application areas

- Aerospace field: used to repair and strengthen key components such as aircraft engine blades and turbine disks.

- Automobile manufacturing field: Surface cladding can be performed on parts such as engine crankshafts and camshafts to improve their wear resistance and corrosion resistance.

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

- Mechanical processing field: surface strengthening and repair of various shafts, gears and other mechanical parts to extend the service life of the parts.
