Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and more specifically, to a dual-gun reinforcement welding machine. Background Technology

[0002] In the manufacturing process of metal structural components, pressure vessels, pipelines, etc., it is often necessary to reinforce the main weld to ensure the strength and sealing of the joint.

[0003] Based on the above, the inventors have discovered that traditional reinforcement welding currently mostly employs single-gun operation, with manual or robotic control of the welding gun moving along the weld seam trajectory. This single-gun welding method has significant drawbacks: firstly, it has low welding efficiency, requiring multiple passes to achieve the required thickness for a single weld, which is time-consuming and energy-intensive; secondly, the weld formation quality is greatly affected by heat input, and continuous single-gun welding easily leads to localized overheating, causing workpiece deformation, stress concentration, and grain coarsening, affecting joint performance. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a dual-gun reinforcement welding machine, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dual-gun reinforcing welding machine, which can achieve synchronous and efficient dual-gun reinforcing welding of the workpiece weld by setting up an independent adjustment mechanism for the two welding guns and a workpiece clamping mechanism, thereby improving welding efficiency and joint strength.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A dual-gun reinforcement welding machine includes a processing table. Cylinder 1 and Cylinder 2 are respectively installed on the upper sides of the processing table. Adjustment mechanism 1 is installed above Cylinder 1 and Cylinder 2, and adjustment mechanism 2 is installed above adjustment mechanism 1. A workpiece seat is provided between Cylinder 1 and Cylinder 2. An L-shaped frame is provided on the side of the workpiece seat. An electric telescopic rod is installed at the upper center of the L-shaped frame. A mounting plate is bolted to the side of the processing table. Limiting bracket 1 and Limiting bracket 2 are bolted to the side of the mounting plate from top to bottom. A pressure sleeve is installed at the lower output end of the electric telescopic rod.

[0009] Furthermore, cylinder one and cylinder two are symmetrically arranged on both sides of the workpiece seat, and a circular protrusion is provided on the upper part of the workpiece seat, which is engaged with the workpiece.

[0010] Furthermore, the adjustment mechanism includes a fixing plate bolted to the top of the cylinder, mounting seats are respectively installed on the upper two sides of the fixing plate, an auxiliary rod and a lead screw are respectively installed between the two sets of mounting seats, an adapter seat is installed on the outside of the auxiliary rod and the lead screw, and a motor is installed at one end of the lead screw.

[0011] Furthermore, the second adjustment mechanism includes a second fixing plate bolted to the top of the first adapter seat. Two sets of symmetrical mounting seats are respectively installed on the side of the second fixing plate. An auxiliary rod and a lead screw are respectively installed between the two sets of mounting seats. The second adapter seat is installed on the outside of the auxiliary rod and the lead screw. A motor is installed at one end of the lead screw. A welding gun is installed on the side of the second adapter seat through a connecting seat.

[0012] Furthermore, support legs are installed at the four corners of the processing table, and a circular pressure groove is formed on the inner side of the pressure sleeve.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, by setting up two independent adjustment mechanisms, namely adjustment mechanism one and adjustment mechanism two, the independent and precise spatial positioning of the two welding guns is realized. Each welding gun is driven by independent horizontal (adjustment mechanism one) and vertical (adjustment mechanism two) adjustment mechanisms. Motor one drives lead screw one to precisely control the lateral position of the welding gun, and motor two drives lead screw two to precisely control the longitudinal height of the welding gun.

[0018] (2) In this solution, a workpiece clamping mechanism consisting of an electric telescopic rod, a pressure sleeve, and two limit holders is set up to achieve stable and reliable clamping of the workpiece. The electric telescopic rod drives the pressure sleeve to press down, pressing the workpiece placed on the workpiece seat between the rubber limit holders one and two. The rubber limit holders can effectively protect the surface of the workpiece from scratches, and the arc-shaped opening on them matches the shape of the workpiece, which can prevent the workpiece from rolling or shifting during the welding process.
