山東焊接專機是為特定的工件和一定形狀的焊接接頭而專門設計的焊接自動化設備。焊接專機的機械系統主要由床身機構、工裝夾具及工件輔助支撐機構、焊槍微調機構、焊接工件或者焊槍移動機構等構成。

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、床身機構：床身主要對設備起支撐作用，可以用鑄造件或者焊接件構成。由于鑄造件生產周期長，成本高，所以現在基本上采用型材和鋼板焊接后，經退火、精加工而成，可以快速制造和成本低，得到大量使用；

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、工裝夾具及輔助支撐機構：可以根據工件的加工面或定位孔，固定工件的相對位置，可以采用手動、氣動、電動、液壓控制夾具運動，實現裝夾和定位工件；

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、焊槍微調機構：要焊槍對準焊縫，需要對焊槍的X\Y\Z向進行三維調節，是焊槍的指向對準焊縫，同時根據焊接工藝要求，還需實現各方向的旋轉功能；

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、焊接工件或焊槍的移動機構：要完成直線、圓周或曲線焊縫的焊接，需要焊槍與工件的焊縫的軌跡的相對運動才能完成焊接要求。可以選擇焊槍移動，也可選擇工件運動。

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.

此外焊接專機系統由機械裝置、供電裝置、控制裝置三大部分組成：

In addition, the special welding machine system is composed of mechanical device, power supply device and control device:

機械裝置：為了適應焊接工藝要求，加壓機構（焊鉗）采用了雙行程快速氣壓傳動機構，通過切換行程控制手柄改變焊鉗開口度，可分為大開和小開來滿足焊接操作要求。

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.

供電裝置：主電力電路由電阻焊變壓器、可控硅單元、主電力開關、焊接回路等組成。目前，我們采用的焊接設備是功率200kVA、次級輸出電壓20V的單相工頻交流電阻焊機。

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.

控制裝置：控制裝置主要提供信號控制電阻焊機動作接通和切斷焊接電流，控制焊接電流值，進行故障監測和處理。

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.
