Vertical type circular seam automatic pipe welder

Abstract

The invention discloses a vertical type circular seam automatic pipe welder. The vertical type circular seam automatic pipe welder comprises a vertical frame, a welding gun assembly and a worktable. The welding gun assembly comprises a box, a first driving mechanism arranged inside the box, a welding gun connected with the driving mechanism in a transmission mode, and an arc striker. The frame is provided with a control screen; the first driving mechanism comprises an air cylinder and an electromagnetic valve; the worktable comprises a base plate and a linear slide rail on the base plate, wherein the linear slide rail is slidingly provided with a mounting rack, the mounting rack is rotatably provided with a turntable, the turntable is fixedly provided with a clamping jaw, a control motor is arranged inside the mounting rack, and the turntable is connected with the control motor in a transmission mode; the base plate is provided with a second driving mechanism for driving the mounting rack to slide; the welding gun the arc striker, the electromagnetic valve, the control motor, the clamping claw and the second driving mechanism are electrically connected with the control screen. The vertical type circular seam automatic pipe welder is high in machining precision, good in welding effects, simple in structure, easy to control, low in manufacturing cost and wide in machining range.

Description

technical field [0001] The invention relates to the technical field of pipe welding machines, in particular to a vertical circular seam automatic pipe welding machine. Background technique [0002] The circular seam automatic welding machine is a general automatic welding equipment that can complete various circular and circular seam welding. It can be used for high-quality welding of carbon steel, low alloy steel, stainless steel, aluminum and its alloys, so it is widely used in machinery manufacturing and other fields. The automatic circular seam welding machine can be divided into two types: the vertical automatic circular seam welding machine and the horizontal circular seam automatic welding machine according to the different workpiece processing structures, among which the vertical circular seam automatic welding machine is well known and common to the public. The structure of the currently known vertical circular seam automatic pipe welding machine mainly includes a ...

Problems solved by technology

[0003] However, the above-mentioned "vertical circular seam automatic pipe welding machine" has the following defects in actual use due to its unreasonable structure: First, because the fixture is fixedly arranged on the workbench, "the workpiece is fixed and the welding torch is rotated" during welding. It is difficult to ensure full contact with the processing position of the workpiece when the welding torch rotates, resulting in low machining accuracy and poor welding effect; second, the driving mechanism first needs to control the vertical movement of the welding torch, and then controls the welding torch to rotate, resulting in The design of the driving mechanism is relatively complicated, the control is difficult, and the manufacturing cost is high; third, due to the processing method of "fixing the workpiece and rotating the welding torch", the welding torch rotates under the action of the driving mechanism, and its rotation radius is limited. Limited range of sizes, narrow scope of application
