山东焊接专机是为特定的工件和一定形状的焊接接头而专门设计的焊接自动化设备。焊接专机的机械系统主要由床身机构、工装夹具及工件辅助支撑机构、焊枪微调机构、焊接工件或者焊枪移动机构等构成。

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、床身机构：床身主要对设备起支撑作用，可以用铸造件或者焊接件构成。由于铸造件生产周期长，成本高，所以现在基本上采用型材和钢板焊接后，经退火、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、工装夹具及辅助支撑机构：可以根据工件的加工面或定位孔，固定工件的相对位置，可以采用手动、气动、电动、液压控制夹具运动，实现装夹和定位工件；

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、焊枪微调机构：要焊枪对准焊缝，需要对焊枪的X\Y\Z向进行三维调节，是焊枪的指向对准焊缝，同时根据焊接工艺要求，还需实现各方向的旋转功能；

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、焊接工件或焊枪的移动机构：要完成直线、圆周或曲线焊缝的焊接，需要焊枪与工件的焊缝的轨迹的相对运动才能完成焊接要求。可以选择焊枪移动，也可选择工件运动。

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.

此外焊接专机系统由机械装置、供电装置、控制装置三大部分组成：

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

机械装置：为了适应焊接工艺要求，加压机构（焊钳）采用了双行程快速气压传动机构，通过切换行程控制手柄改变焊钳开口度，可分为大开和小开来满足焊接操作要求。

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.

供电装置：主电力电路由电阻焊变压器、可控硅单元、主电力开关、焊接回路等组成。目前，我们采用的焊接设备是功率200kVA、次级输出电压20V的单相工频交流电阻焊机。

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.

控制装置：控制装置主要提供信号控制电阻焊机动作接通和切断焊接电流，控制焊接电流值，进行故障监测和处理。

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.
