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.
