Embodiment 1

[0033] exist figure 1 In the first embodiment shown, the corner sleeve 5 is fixed to the guide wire rod 2; the swing angle mechanism is also provided with a fixed plate 7, a swing angle motor 8, and a driving gear 9 arranged on the swing angle motor shaft 1. The swing angle ring gear 10 and the swing plate 11 meshed with the driving gear; the fixed plate 7 and the connecting plate 4 are insulated and fixed; the guide wire rod 2 is pivoted with the fixed plate 7, and the swing angle gear The ring 10 is fixed with the fixed plate 7, the guide wire rod 2, the swing angle motor 8 and the wire feeding device 1 are all fixed on the swing plate 11, and the rotation axis of the swing angle ring gear and the The swing axis of the swing plate is coaxial with the guide wire rod.

[0034] When a certain side of the weld groove needs to be welded, the controller controls the rotation of the swing angle motor 8. Since the swing angle ring gear 10 is fixed on the fixed plate, the angle of t...

Embodiment 2

[0036] The corner cover 5 is fixed with the guide wire rod 2; the swing angle mechanism is also provided with a fixed plate 7, a swing angle motor 8, a driving gear 9 arranged on the swing angle motor shaft, and a pendulum meshed with the driving gear. Angle ring gear 10 and swing plate 11; said fixed plate 7 is insulated and fixed to said connecting plate 4; Fixed, the swing angle ring gear 10, the wire feeding device 1, the guide wire rod 2 and the swing plate 11 are fixed; and the rotation axis of the swing angle gear ring and the swing axis of the swing plate are connected with the guide wire Rod coaxial.

[0037] When a certain side of the weld groove needs to be welded, the controller controls the rotation of the swing angle motor 8, and drives the swing angle ring gear to rotate around the rotation axis by an angle through the driving gear. Since the swing angle ring gear 10 is fixed on the swing plate 11 , then the swing angle ring gear will drive the swing plate 11 t...

Embodiment 3

[0039] like figure 2 As shown, the corner sleeve 5 is pivoted with the guide wire rod 2 through bearings; the swing angle mechanism is also provided with a fixed plate 12, a swing angle motor 8, and a driving gear 9 arranged on the swing angle motor 8 shaft. 1. The swing angle ring gear 10 and the swing plate 11 meshed with the driving gear 9; the fixed plate 12 is insulated and fixed from the connecting plate 4, and a fan-shaped hole 13 is arranged in the middle; the wire feeding device 1 and the guide wire The rod 2 is fixed on the fixed plate 12, the swing plate 11 is set in the fan-shaped hole 13 of the fixed plate 12, and the corner sleeve 5 is located at the tip of the fan-shaped hole, and the swing angle ring gear 10 Fixed with the swing plate 11 and parallel to the arc of the fan-shaped hole, the swing angle motor 8 is fixed with the fixed plate 12 .

[0040] The difference between this embodiment and Embodiments 1 and 2 is that the swinging part of the welding torch...

Abstract

The invention relates to a narrow-gap welding nose with a tilt angle device, which carries out narrow-gap welding. The narrow-gap welding nose with the tilt angle device comprises an electric conduction nozzle of a welding gun, a connecting plate for installing the welding gun, and a tilt angle device, wherein the lower end of the electric conduction nozzle is provided with a bent part; and the bent part is coaxially and fixedly arranged on the lower end of a wire guide rod by a corner sleeve. The narrow-gap welding nose with the tilt angle device is characterized in that the tilt angle device comprises a tilt angle mechanism for driving the electric conduction nozzle to carry out deflection, and a side wall tracking mechanism for keeping the distance between the electric conduction nozzle and the side wall, wherein the tilt angle mechanism for driving the electric conduction nozzle to carry out deflection is connected with the electric conduction nozzle; the side wall tracking mechanism comprises an oscillating rod, an angle sensor and a controller, wherein the oscillating rod is used for supporting the side wall of a groove; the angle sensor is connected with the oscillating rod and is connected with the controller; the controller controls the tilt angle mechanism; and the oscillating rod and the side wall of the groove are always in elastic contact. The lateral displacement moving amount of a workpiece is measured by a high-precision sensing assembly, and the distance between the electric conduction nozzle and the workpiece is controlled to be within a tracking precision of + / -0.5mm by the lateral regulation of the control system so as to guarantee the stable and even penetration of the side wall.

Description

technical field [0001] The invention relates to a narrow-gap welding head in the field of welding equipment, in particular to a narrow-gap welding head with a swing angle device for single-wire double-pass multilayer narrow-gap welding. Background technique [0002] Narrow gap welding is used for butt welding of thick plates. Before welding, there is no groove or only a small angle groove, and a narrow and deep gap is left. The whole weld is completed by multi-layer welding of gas shielded welding or submerged arc welding. . Due to the small groove gap, the cross-sectional area of ​​the thick plate weld is greatly reduced, thereby reducing the welding engineering quantity and production cost; due to its small linear energy, it can be used for welding high-strength steel and fine-grain steel. In various narrow gap welding methods, the core problem to be solved is to ensure the fusion of the side walls of the groove, and the uniform and stable penetration of the two side wall...
