Four-axis CNC automatic welding machine

1)the main structure

The main machine of the CNC automatic welding machine includes X, Y, Z axis linear motion and R axis rotary motion to realize the linear or curved motion of the welding space and the welding angle adjustment of the welding torch to the workpiece, thereby completing the welding of various special-shaped welds. The X, Y, and Z axis motion systems are driven by AC servo motors, driven by ball screws and guided by guide rails to achieve precise control of walking. It can manually adjust and control the welding angle adjustment requirements of the welding gun and the workpiece, and cooperate with the X, Y, and Z axes to achieve the completion of the welding process.

2), auxiliary equipment

1. Support welding power sources such as argon arc welding, gas shielded welding, submerged arc welding, etc.

2. Pneumatic welding fixture (one set contains six pairs)

3), the welding platform and welding fixture description

Pneumatic positioning and clamping fixture can realize fast clamping and positioning of workpieces. Six welding fixtures are placed on a welding platform, and three pairs of fixtures are arranged on the left and right sides. It adopts double-station mode, and it will reset automatically after welding on the left. If the assembly on the right side is completed, welding is performed automatically to the right side, and the workpiece is loaded and unloaded manually at the left station.

4), the electrical control system

Four-axis DOF space trajectory motion (straight line, circular arc, spiral curve). · Teach-type input of trajectory parameters, simple and convenient operation, and support teaching graphics preview function to compare whether the processed processing file is consistent with the actual graphics.

Features:

1.The X, Y, Z, and D axes of the workpiece to be welded are step-driven to meet the needs of large strokes

2.High production efficiency, fast welding speed and automatic batch production

3.Can weld any point, straight line, circle, elliptical machine square and other arbitrary trajectories

4.With auto focus and rotation functions, it can weld products of any shape in 3D space

Product advantages:

1. The ceramic cavity imported from the United Kingdom is used for high photoelectric conversion efficiency. 2. CCD image monitoring ensures the stability of welding quality.

3.Specialized automatic tooling fixtures can be customized to achieve mass production of products

4. The laser power density is large. After the workpiece absorbs the laser, the temperature rapidly rises and melts or vaporizes, even if the melting point is high, the hardness and brittle material are high.

Materials (such as ceramics, diamonds, etc.) can also be processed by laser;

5. The laser head is not in contact with the workpiece, and there is no problem of wear of processing tools;

6. The workpiece is not stressed and is not easy to be polluted;

7. It can process the moving workpiece or the material sealed in the glass shell;

8. The divergence angle of the laser beam can be less than 1 milli-arc, the spot diameter can be as small as micrometers, and the action time can be as short as nanoseconds and picoseconds.

Rate laser's continuous output power can reach kW to ten

On the order of kilowatts, the laser is suitable for both precision microfabrication and large material processing;

9.The laser beam is easy to control, and it is easy to combine with precision machinery, precision measurement technology and electronic computer to realize high automation of processing.

And achieve high processing accuracy;

10. Robots can be used for laser processing in harsh environments or places that are difficult for others to access.
