Description

Technical Field

[0001] This application relates to the field of welding equipment, and more specifically, to a blow welding device. Background Technology

[0002] Blow jet welding is an advanced welding process that combines blow gas protection with spray coating technology. During the welding process, on the one hand, a protective gas of a specific composition, such as argon or carbon dioxide, is delivered to the welding area through a precise blow gas device. This effectively isolates the weld area from air, preventing reactions between the weld and oxygen, nitrogen, etc., and avoiding defects such as porosity and oxidation, thereby improving the quality and performance of the weld joint. On the other hand, spray coating technology is used to pre-treat the workpiece surface before welding, applying a suitable coating material to improve the surface condition of the workpiece and enhance the bonding strength between the weld and the base material. Alternatively, post-weld protection treatment can be applied to the weld to improve its corrosion resistance and wear resistance. It is widely used in aerospace, automotive manufacturing, precision machining, and other fields.

[0003] Currently, there are many types of automated welding equipment on the market, among which the most common are fixed welding machines and general-purpose welding robot workstations. Fixed welding machines are typically designed specifically for particular workpieces and welding processes, and their structure is relatively fixed. While they can achieve efficient welding of specific workpieces, they lack flexibility. If the workpiece specifications or welding process change, large-scale modifications or even redesigns of the equipment are required, which not only increases production costs but also extends the production cycle. General-purpose welding robot workstations, while highly flexible and adaptable to welding needs of workpieces of various shapes and sizes, are prone to wobbling when operating on uneven ground, affecting welding accuracy. Therefore, this application proposes a jet welding device. Utility Model Content

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-4 As shown, this utility model provides a blow welding device, including a base 1, a robotic welding module 3, and an electrical control cabinet 16. The base 1 is welded from high-strength steel, possessing good rigidity and stability. Multiple fixing plates 12 are fixed around the bottom of the base 1, and each fixing plate 12 is vertically mounted with a stud 13. The top of the stud 13 is threaded through the fixing plate 12 and the base 1, allowing for easy adjustment of the stud 13's installation height. A foot block 14 is fitted to the bottom of the stud 13, and the foot block 14 is designed as a frustum, which increases the contact area with the ground and improves the stability of the device. A rubber pad is provided on the lower surface of the foot block 14, providing good elasticity and anti-slip properties, effectively reducing vibration and noise generated during operation and preventing the device from sliding. A hexagonal sleeve 15 is fixedly fitted at the bottom of the stud 13. The stud 13 can be easily rotated by using a wrench or other tools through the hexagonal sleeve 15 to adjust the height of the foot block 14, so that the equipment can remain level and stable on uneven ground.

[0024] Furthermore, in this embodiment, a pair of linear electric slide rails 2 are arranged side by side along the length of the top of the base 1. The linear electric slide rails 2 adopt a high-precision ball screw drive, which features smooth movement and high positioning accuracy. The robot welding module 3 slides in cooperation with the pair of linear electric slide rails 2. Driven by the linear electric slide rails 2, the robot welding module 3 can move linearly back and forth along the linear electric slide rails 2. The robot welding module 3 is equipped with a cable chain 4, which is used to organize and protect the cables and air pipes of the robot welding module 3, preventing them from getting tangled and damaged during movement, and ensuring the normal operation of the robot welding module 3.

[0025] Furthermore, in this embodiment, a workpiece bearing base 5 is also provided on the base 1. The workpiece bearing base 5 is made of high-strength aluminum alloy material to provide stable support for the workpiece. The workpiece positioning assembly 6 is assembled on the workpiece bearing base 5. The workpiece positioning assembly 6 includes a mounting bracket 9 fixed on the base 1 and an electric push rod 10 vertically mounted on the mounting bracket 9. The electric push rod 10 is driven by a high-performance servo motor, which has the characteristics of large thrust and fast response speed. The telescopic end of the electric push rod 10 is connected to a positioning block 11. Through the telescopic movement of the electric push rod 10, the positioning block 11 can be moved up and down, thereby realizing the positioning and fixing of the workpiece.

[0026] Furthermore, in this embodiment, brackets 7 are fixed at both ends of the top of the base 1 facing the workpiece bearing base 5. The brackets 7 are welded from steel and have sufficient strength and stability. A crossbar 8 is connected between the top ends of a pair of brackets 7. The crossbar 8 serves to enhance the structural stability and also provides an installation position for auxiliary equipment.

[0027] Furthermore, in this embodiment, an electrical control cabinet 16 is provided at one end of the base 1. The electrical control cabinet 16 adopts a sealed design, providing excellent dustproof and waterproof performance. In addition, the electrical control cabinet 16 integrates a PLC, HMI, servo drive, and welding power supply. The PLC programmable logic controller can precisely control the operation of the entire equipment, while the HMI human-machine interface provides an intuitive operating interface, facilitating parameter setting and equipment monitoring by operators. The electrical control cabinet 16 is connected to components such as the robot welding module 3 and the electric push rod 10 via cables, and is used to control the workpiece positioning component 6 to fix the workpiece, as well as to control the linkage control of the welding robot axis movement and welding process in the robot welding module 3.

[0028] Working Principle: In operation, the workpiece to be welded is first placed on the workpiece support base 5. Then, the control cabinet 16 sends a control signal to extend the electric push rod 10. The electric push rod 10 moves the positioning block 11 downwards until it contacts the workpiece and firmly fixes it on the workpiece support base 5, ensuring the workpiece will not move during welding and thus guaranteeing welding quality. The control cabinet 16 controls the linear electric slide rail 2 according to the preset welding program. The linear electric slide rail 2 drives the robot welding module 3 to move linearly back and forth along its length, bringing it to the designated welding position. Simultaneously, the control cabinet 16 also controls the movement of each axis of the welding robot in the robot welding module 3, adjusting the posture and position of the welding gun to adapt to the welding requirements of workpieces of different shapes and sizes. After the robot welding module 3 reaches the welding position, the control cabinet 16 starts the welding power supply and simultaneously controls the welding robot to perform welding operations according to the preset welding parameters. After the welding operation is completed, the electrical control cabinet 16 shuts off the welding power supply and simultaneously drives the electric push rod 10 to retract, causing the positioning block 11 to move away from the workpiece and releasing the workpiece from its fixation. Then, the linear electric slide rail 2 is controlled to drive the robot welding module 3 back to its initial position.
