Description

Technical Field

[0001] This utility model relates to the technical field of welding head adjustment structure, specifically a welding head adjustment structure for welding medium and thick plates. Background Technology

[0002] A welding head is a component in welding equipment used to conduct current, generate an electric arc, and melt the welding rod or wire to achieve a weld connection. Common welding heads typically consist of a contact tip, electrode chuck, and nozzle. The contact tip guides the welding current to the welding rod or wire and ensures stable current transmission; the electrode chuck clamps the welding rod or wire, ensuring a good electrical connection with the welding power source; the nozzle protects the welding area from air intrusion and guides the shielding gas to evenly cover the welding area, improving weld quality.

[0003] Traditional welding joints are typically connected using a fixed connection method. This makes it inconvenient to adjust the welding joint angle, resulting in poor adaptability to welded parts, limitations on complex-shaped welded parts, difficulty in adapting to changes in welded part specifications, and difficulty in optimizing the welding angle. Consequently, production efficiency is low and operation is more difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a welding head adjustment structure for welding medium and thick plates, so as to solve the problems mentioned in the background art, which are that traditional welding heads are generally connected by a fixed connection method, the welding head angle is inconvenient to adjust, the adaptability of the weldment is poor, the weldment with complex shape is limited, the weldment specification changes are difficult to adapt to, the welding angle is difficult to optimize, resulting in low production efficiency and increased operation difficulty.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding head adjustment structure for welding medium-thick plates, comprising a connecting base, with sliding grooves formed in the middle of both side walls of the connecting base, connecting legs fixedly connected to the four corners of the bottom of the connecting base, a driving assembly slidably engaged at the bottom of the connecting base, a first sliding frame slidably connected inside the sliding grooves, a first threaded rod rotatably connected to the middle of the first sliding frame, a movable seat threadedly connected to the middle of the first threaded rod, support rods symmetrically fixedly connected inside the first threaded rod, two of the support rods penetrating the movable seat, and the movable seat... A limiting component is fixedly connected to the top surface, and a support component is rotatably connected to the middle of the movable seat. An angle adjustment component is fixedly connected to the top of the support component. The design of this device allows the welding head to adapt to various complex shapes of weldments after connection, easily reaching different positions and angles of the weldment, facilitating omnidirectional welding. It can quickly adapt through multi-directional displacement, saving time and costs, improving production efficiency. The position and angle of the welding head can be precisely adjusted according to the shape and direction of the weld, ensuring that the welding arc always maintains the optimal relative position and angle with the weld, improving operational convenience and enhancing the applicability of the device.

[0006] Preferably, the drive assembly includes two mounting slots, which are symmetrically opened at the bottom of the two side walls of the connecting base. A straight slot is opened through the side wall of the mounting slot. A second sliding frame is slidably engaged inside the mounting slot.

A rotation limiting ring is rotatably connected inside the fixed ring seat. A fixed column is fixedly connected to the middle of the top surface of the rotation limiting ring. A magnetic suction ring seat is fixedly connected to the outer side of the bottom end of the fixed column. The magnetic suction ring seat is mainly used to fix the degree of movement of the limiting arm after the limiting arm and the rotation limiting ring are engaged.

[0010] Preferably, the angle adjustment assembly includes two fixed vertical plates, which are symmetrically fixedly connected to the top of a fixed column. A swing arm is rotatably connected between the two fixed vertical plates. A fixed top plate is fixedly connected to the top of the swing arm by bolts. Positioning holes are opened at equal angles on both fixed vertical plates. Positioning bolts are threaded into the positioning holes and penetrate the bottom of the swing arm. The positioning bolts and positioning holes are designed to position the swing arm at different angles, so that the angle of the welding torch can be adjusted after installation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The movable seat designed in this device can move along the direction of the support rod and the second threaded rod when the first threaded rod and the second threaded rod are used in conjunction with the adjusting wheel. This makes the position of the movable seat variable, and the combination of the two makes the movement of the movable seat more flexible. Through the design of the fixed vertical plate, swing arm, fixed top plate, positioning hole and positioning bolt, the swing arm can rotate inside the fixed vertical plate, making the angle of the swing arm adjustable, which is convenient for different welding positions and improves welding convenience.

The swing angle of the swing arm 21 is determined according to the actual situation, and then the positioning bolt 24 is inserted into the positioning hole 23 to fix the angle of the swing arm 21.
