Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to an automatic welding machine. Background Technology

[0002] In modern industrial production, welding is a key processing technology widely used in many fields such as automobile manufacturing, electronic equipment production, and aerospace. With the rapid development of the manufacturing industry, the requirements for welding quality, efficiency, and automation are increasing day by day.

[0003] Traditional welding methods, such as manual welding, while offering advantages in flexibility, suffer from numerous insurmountable drawbacks. Manual welding heavily relies on the individual skill and experience of the welder, leading to significant differences in skill levels among welders. This results in inconsistent weld quality, making it difficult to guarantee product consistency and stability. Furthermore, manual welding is inefficient and cannot meet the ever-increasing production capacity demands of large-scale manufacturing. Utility Model Content

[0004] To address the above problems, this utility model provides an automatic welding machine.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic welding machine includes a housing, an mounting plate fixedly installed on the upper end of the housing, the upper end of the mounting plate being used to place a workpiece to be welded, and a pressing mechanism for fixing the workpiece being provided on the upper end of the mounting plate. A rod is fixedly installed on the upper end of the housing, and a welding mechanism is provided on the upper end of the rod.

[0007] Preferably, the pressing mechanism includes a first cylinder fixedly mounted on one side of the upper end of the mounting plate, and a first drive rod is fixedly mounted on the output end of the first cylinder.

[0008] Preferably, a first rotating rod is installed on one side of the mounting plate. The first rotating rod is L-shaped, and the bent part of the first rotating rod is rotatably connected to the mounting plate. The upper end of the first rotating rod is rotatably connected to the end of the first drive rod. A first pressure plate is rotatably installed on the lower end of the first rotating rod, and the first pressure plate presses one side of the workpiece.

[0009] Preferably, a second cylinder is fixedly installed on the other side of the upper end of the mounting plate, and a second drive rod is fixedly installed on the output end of the second cylinder. A second rotating rod is installed on the other side of the mounting plate. The second rotating rod is also L-shaped. The bend of the second rotating rod is rotatably connected to the mounting plate. The upper end of the second rotating rod is rotatably connected to the end of the second drive rod. A second pressure plate is rotatably installed on the lower end of the second rotating rod. The other side of the workpiece is pressed by the second pressure plate.

[0010] Preferably, the welding mechanism includes an ultrasonic welding machine fixedly installed on the upper end of the rod, and a welding head for welding the workpiece is fixedly installed on the bottom of the ultrasonic welding machine.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The pressing mechanism adopts a dual-cylinder and dual-rotor linkage design. The first and second pressure plates simultaneously press and fix the workpiece from both sides, ensuring that the workpiece will not shift during welding, effectively improving welding accuracy and quality. The welding mechanism is equipped with an advanced ultrasonic welding machine. High-frequency vibration enables rapid welding, which greatly shortens welding time and improves production efficiency compared to traditional welding methods. At the same time, the energy-saving characteristics of ultrasonic welding reduce energy consumption and lower production costs.

[0013] 2. The machine housing is made of high-strength metal, and the rod body is made of high-strength alloy material. This not only provides solid support for all components of the equipment but also effectively resists external impacts and the effects of harsh working environments, ensuring long-term stable operation of the equipment. The cooperation between the cylinder and the drive rod enables precise control of the movement of the rotating rod and the pressure plate, achieving reliable fixation of workpieces of different sizes and shapes, and meeting diverse welding needs.

[0020] Reference Figure 1-2 An automatic welding machine mainly consists of core components such as a housing 1, a mounting plate 2, a pressing mechanism, a rod 7, and a welding mechanism.

[0021] The housing 1, serving as the support and protective structure for the entire equipment, is constructed from high-strength metal, possessing excellent stability and durability, and effectively resisting the effects of external impacts and harsh working environments. The mounting plate 2 is securely fixed to its upper end. The surface of the mounting plate 2 has undergone special treatment, making it flat and smooth, specifically designed to hold the workpiece to be welded, ensuring the workpiece remains stable during the welding process.

[0022] The pressing mechanism plays a crucial role in the entire welding process, primarily responsible for firmly securing the workpiece to ensure welding quality. The pressing mechanism includes a first cylinder 3 mounted on one side of the upper end of the mounting plate 2. The first cylinder 3 employs advanced pneumatic technology, ensuring stable operation and strong power. Its output end is tightly connected to the first drive rod 4, allowing precise control of the extension and retraction of the first drive rod 4 when the first cylinder 3 is activated.

[0023] An L-shaped first rotating rod 5 is mounted on one side of the mounting plate 2. The bend of the first rotating rod 5 is flexibly connected to the mounting plate 2 via a high-precision rotating shaft, ensuring smooth and unobstructed rotation. The upper end of the first rotating rod 5 is also rotatably connected to the end of the first drive rod 4. This design allows the first drive rod 4 to drive the first rotating rod 5 to rotate accordingly when it extends or retracts. A first pressure plate 6 is mounted on the lower end of the first rotating rod 5 via a rotating joint. When the first rotating rod 5 rotates, the first pressure plate 6 can move downwards, pressing firmly on one side of the workpiece to prevent displacement during welding.

[0024] To further enhance the workpiece fixation effect, a second cylinder is also equipped on the other side of the upper end of the mounting plate 2. The second cylinder has the same high-quality performance as the first cylinder, and a second drive rod is fixedly mounted on its output end. A second rotating rod, also L-shaped, is mounted on the other side of the mounting plate 2. The bend of the second rotating rod is rotatably connected to the mounting plate, its upper end is rotatably connected to the end of the second drive rod, and a second pressure plate is rotatably mounted on its lower end. By driving the second drive rod with the second cylinder, the second rotating rod and the second pressure plate press against the other side of the workpiece, achieving omnidirectional and stable fixation of the workpiece.

[0025] The welding mechanism is the core working part of the automatic welding machine. It is installed on the upper end of the rod 7 fixed to the upper part of the housing 1. The rod 7 is made of high-strength alloy material, which has sufficient rigidity and strength to stably support the welding mechanism and ensure that it will not shake during operation. The welding mechanism is mainly composed of an ultrasonic welding machine 8, which adopts advanced ultrasonic welding technology and has the advantages of high efficiency, energy saving, and high welding quality. A welding head 9 for welding workpieces is fixedly installed at its bottom. The welding head 9 is carefully designed to accurately transmit ultrasonic energy to the welding part of the workpiece. Through high-frequency vibration, the welding surface of the workpiece is rapidly heated and fused, thereby achieving high-quality welding operation.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
