Tracking device for tank-type double-gun horizontal circular/longitudinal seam welder

Abstract

The invention relates to a welding device, in particular to a mechanical tracking device applied to a tank-type double-gun horizontal circular / longitudinal seam welder. The device mainly comprises a tracking roller (1), a roller shaft (2), a roller bracket (3), a left-handed and right-handed screw rod (4), a thin lock nut (5), a coupling screw (6), a downward spring adjusting screw rod (7), a support sleeve lock screw (8), a tracking extension spring (9), a spring bushing (10), a thin lock nut (11), an upward spring adjusting screw rod (12), an elevating cylinder (13), a linear slide rail and slide block (14), a welding gun (15), a three-dimensional crossed fine tuning mechanism (16) and the like. The tracking of circular / longitudinal seam welding can be realized. Simultaneously, seams are detected by a mechanical method without disturbing normal work of a welder or causing adverse effect on an electric arc of the welder, so that operation is more convenient and cost is low.

Description

technical field [0001] The present invention relates to a welding device, more specifically, the present invention relates to a mechanical tracking device applied to a double gun horizontal ring and longitudinal seam welding machine for a tank body. Background technique [0002] At present, the commonly used welding tracking device is a weld confirmation device that monitors the welding effect. For example, it is equipped with a camera that collects images of the weld, collects images of the weld at any time, and uses video sensing technology to replace manual determination of the welding effect of the workpiece. The device mainly relies on electrical tracking, which will interfere with the normal work of the welding machine. Or a weld detection device that monitors the welding effect, such as an infrared detector, etc., using infrared scanning points to detect whether the contact between the gun tip and the weld is accurate. form adverse effects. [0003] Therefore, it is...
