Shandong welding machine is a welding automation equipment specially designed for specific workpieces and welding joints of certain shapes. The mechanical system of the special welding machine is mainly composed of bed mechanism, tooling fixture and workpiece auxiliary support mechanism, welding torch fine adjustment mechanism, welding workpiece or welding torch moving mechanism, etc.
1. Bed mechanism: the bed mainly supports the equipment and can be made of cast parts or welded parts. Due to the long production cycle and high cost of cast parts, they are basically made by welding profiles and steel plates, annealing and finishing, which can be rapidly manufactured and low-cost, and are widely used;
2. Fixture and auxiliary support mechanism: the relative position of the workpiece can be fixed according to the machining surface or positioning hole of the workpiece. Manual, pneumatic, electric and hydraulic control of fixture movement can be used to realize clamping and positioning of the workpiece;
3. Fine adjustment mechanism of welding gun: to align the welding gun with the weld, three-dimensional adjustment of the X \ y \ Z direction of the welding gun is required. It is the pointing of the welding gun to the weld. At the same time, according to the requirements of the welding process, it also needs to realize the rotation function in all directions;
4. Moving mechanism of welding workpiece or welding torch: to complete the welding of linear, circumferential or curved welds, the relative movement of the weld trajectory of the welding torch and the workpiece is required to complete the welding requirements. You can select the movement of the welding gun or the movement of the workpiece.
In addition, the special welding machine system is composed of mechanical device, power supply device and control device:
Mechanical device: in order to meet the requirements of welding process, the pressurizing mechanism (welding tongs) adopts a double stroke fast pneumatic transmission mechanism. The opening of the welding tongs can be changed by switching the stroke control handle, which can be divided into large opening and small opening to meet the requirements of welding operation.
Power supply device: the main power circuit is composed of resistance welding transformer, thyristor unit, main power switch, welding circuit, etc. At present, the welding equipment we use is a single-phase power frequency AC resistance welding machine with a power of 200KVA and a secondary output voltage of 20V.
Control device: the control device mainly provides signals to control the resistance welding machine to switch on and off the welding current, control the welding current value, and conduct fault monitoring and treatment.
Of course, it should be noted that when purchasing or customizing the equipment, you should carefully consider whether the design and price are reasonable, so as to avoid buying a special plane with serious quality risks.
