Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and more particularly to an automatic welding device and a welding method for a steel pipe cross arm. Background Art

[0002] In power engineering construction, steel tube pole crossarms are key components supporting transmission lines, and their welding quality is directly related to the safe and stable operation of transmission lines. With the development of the power industry, the demand for steel tube pole crossarms is increasing. Traditional manual welding methods can no longer meet the production efficiency and quality requirements. Therefore, automated welding equipment has been widely used in the production of steel tube pole crossarms.

[0003] A Chinese patent discloses a low-voltage four-wire cross-arm welding tool and an automated welding device and method (authorization announcement number CN116460507B). It is a low-voltage four-wire cross-arm welding tool and an automated welding device and method. In view of the problem that there are many steps in the installation and removal of angle steel in the prior art, which affects the installation and removal efficiency and requires workers to rotate the tool while welding, the following solution is proposed, which includes: a tool and an angle steel, the bottom of the tool is fixedly connected to a bottom plate, and the bottom of the bottom plate is fixedly embedded with multiple magnets; a length limiting structure is set on the tool It is used to clamp the angle steel in the center on the top of the tooling to facilitate subsequent welding. In the present invention, the length limiting structure and the clamping structure can be driven separately by rotating the rotating shaft, so that the angle steel can be placed in the center and can also be clamped. The first rack and the second rack cooperate to automatically complete the clamping and disassembly of the angle steel. In addition, the welding structure can automatically weld on the four sides of the M-shaped pad to improve welding efficiency. However, the device still requires manual assistance in welding operations, and cannot reach the level of automation. The efficiency is low. Secondly, deformation and skewness are more common in automated welding. During the welding process, due to the uneven heating of the welding heat source, thermal stress and temperature gradients will be generated in the weld and surrounding areas. After the welding is completed, these areas cool and shrink inconsistently, which causes the steel pipe crossarm to deform.

[0004] During welding, the uneven internal stress of the workpiece material can easily lead to weld penetration problems. Weld penetration defects will seriously weaken the bearing capacity of the steel pipe pole crossarm, making it unable to meet the design requirements and greatly threatening the safe operation of the transmission line.

[0005] To ensure product quality, manual inspection is currently commonly used to individually check welded steel pipe crossarms. However, this method is not only inefficient, but also difficult to ensure the accuracy and consistency of test results due to the subjectivity and fatigue of manual inspection. Manual inspection may fail to detect minor deformation, skewness, and weld penetration defects in a timely manner, resulting in substandard products entering the market and posing a safety hazard to power projects. Therefore, it is of great practical significance to develop an automated welding device for steel pipe crossarms that can effectively address welding deformation, skewness, and weld penetration issues, and can efficiently and accurately detect welding quality.

When the steel workpiece 1 can be fed into the position of the feed interface 201, the steel workpiece 1 will be driven to move sideways by the upper electric roller 16. At this time, as the steel workpiece 1 is continuously fed, multiple steel workpieces 1 will be continuously pushed and automatically welded by the machine;

[0056] The welding device includes a lifting connecting plate 17 fixedly mounted on the upper end of the lifting platform 20. A pair of electric-controlled welding guns 18 are provided at the lower end of the lifting connecting plate 17. The electric-controlled welding guns 18 can be controlled to move forward and backward by the lifting connecting plate 17, thereby completing the welding operation on the welding workpiece 19.

[0057] A lifting member 7 is fixedly installed on the side of the middle part of the support member 9, and a lifting motor 11 is fixedly installed on the middle part of the lifting member 7. A feeding motor 1101 is fixedly installed on the lower side of the lifting motor 11 of the lifting member 7. The output end of the feeding motor 1101 is meshed and connected with the linkage gear plate 2001. A transmission belt 1102 is fixedly installed on the lower end of the inner cavity of the support member 9. A limiting member 901 is fixedly installed on the upper end of the transmission belt 1102 of the support member 9. The feeding motor 1101 controls the rotation of the transmission belt 1102. The transmission belt 1102 can drive the welding workpiece 19 to move horizontally.

When the welding workpiece 19 moves to the position of the welding device on the transmission belt 1102, it will fall from the square slot opened on the support member 9 at the welding device position to the upper side of the steel workpiece 1, thereby facilitating subsequent automatic welding processing;

[0059] The flipping device includes a rotating motor 24 fixedly mounted in the middle of the stabilizing plate 3. A flipping member 25 is fixedly mounted on the output end of the rotating motor 24. When the welding workpiece 19 is detected to be leaking or tilted, the rotating motor 24 can drive the flipping member 25 to flip, thereby causing the steel workpiece 1 to fall.

[0060] An electric partition 23 is fixedly installed on the side of the support member 9 close to the discharge member 8, a turning groove 33 is provided on the side of the stabilizing plate 3 located at the turning device, a waste trough 26 is fixedly installed on the lower side of the turning device, and a limiting groove 30 is provided on the front side of the stabilizing plate 3 located at the support seat 29. Unqualified steel workpieces 1 after welding will fall into the waste trough 26, thereby facilitating subsequent recycling and improving the qualified rate. When the steel workpiece 1 moves horizontally on the upper side of the feed member 2, the limiting groove 30 can limit and guide the side of the steel workpiece 1 to prevent the steel workpiece 1 from tilting during the horizontal movement;

[0061] The pressure sensing device includes a limit plate 28 rotatably mounted on the lower end of the support member 9, a contact spring 27 fixedly mounted on the upper end of the limit plate 28, and a pressure sensor provided on the upper end of the limit plate 28. When the welding workpiece 19 is warped or skewed during welding, the welding workpiece 19 will apply a horizontal force to the lower end of the limit plate 28, thereby causing the upper end of the limit plate 28 to press the contact spring 27 until the pressure sensor provided on the upper end of the limit plate 28 is triggered.

[0062] The airflow device includes an electric push rod 35 fixedly mounted on the upper end of the stabilizing plate 3, an auxiliary air guide 34 fixedly mounted on the front side of the electric push rod 35, and a wind pressure sensing head 36 fixedly mounted in the middle of the auxiliary air guide 34. The electric push rod 35 can push the auxiliary air guide 34 forward until the auxiliary air guide 34 and the fixed air guide 31 seal and clamp the two ends of the welding workpiece 19, and then the electric air outlet 32 ​​fills the space between the auxiliary air guide 34 and the fixed air guide 31 with inert gas, so that the welding workpiece 19 can be detected;

[0063] Step 1: Connect the feeding device of the steel workpiece 1 and the feeding device of the welding workpiece 19 to the feeding interface 201 and the connector 10 respectively;

[0064] Step 2: The synchronizing module of the main control module inside the main control box 6 can control the conveying speed of the workpiece conveying module and the splicing piece conveying module for the steel workpiece 1 and the welding workpiece 19;

[0065] Step 3: The steel workpiece 1 moves along the turning member 25 to the bottom of the welding device, and the welding workpiece 19 is dropped onto the upper side of the steel workpiece 1 by the conveyor belt 1102. The steel workpiece 1 and the welding workpiece 19 are then spliced ​​and welded together by the welding device.

[0066] Step 4: After welding, the finished workpiece is pushed by the pressure of the workpiece on the front side and is detected by the pressure sensing device and the airflow device respectively. If defects are found, the flipping device is started and the waste parts are recycled. If there are no defects, the material is discharged normally.

[0067] The working principle of the present invention is as follows: the operator connects the feeding device of the steel workpiece 1 and the feeding device of the welding workpiece 19 to the feeding interface 201 and the connecting head 10 respectively. When the steel workpiece 1 can be fed into the position of the feeding interface 201, the steel workpiece 1 will be driven to the side by the upper electric roller 16. At this time, as the steel workpiece 1 is continuously fed, multiple steel workpieces 1 will be continuously pushed and moved to the bottom of the electric-controlled welding gun 18. At the same time, since the input end of the main control module is provided with a synchronization module, the synchronization module is connected to the workpiece transmission module and the assembly transmission module, and the feeding motor 1101 is driven The driving belt 1102 rotates, thereby bringing the welding workpiece 19 on the upper side of the driving belt 1102 toward the direction of the electric-controlled welding gun 18. A recovery fan 22 is fixedly installed on the rear side of the inner cavity of the support 9. The support 9 is provided with a square groove at the position of the welding device. When the welding workpiece 19 moves to the position of the welding device on the driving belt 1102, it will fall from the square groove position of the support 9 at the welding device position to the upper side of the steel workpiece 1. When the welding workpiece 19 contacts the steel workpiece 1, the main control box 6 controls the workpiece transmission module and the splicing part transmission module to stop. At this time, the lifting motor 11 starts The lifting platform 20 is driven downward by the linkage gear plate 2001, and the stabilizing member 21 limits and fixes the welding workpiece 19. At this time, the welding module is started, and the electric welding gun 18 welds the connection position of the welding workpiece 19 and the steel workpiece 1. The welding operation can be performed automatically without human intervention. When the welding is completed, the electric spacer 23 pops up. At this time, the electric roller 16 continues to push the next steel workpiece 1 to move, and the welded workpiece moves to the upper side of the flip part 25. After that, the electric spacer 23 starts to press down, and the electric push rod 35 pushes the rotating motor 24 to the fixed The fixed air guide 31 moves in the direction until the auxiliary air guide 34 and the fixed air guide 31 seal and clamp the two ends of the welding workpiece 19. Then the electric air outlet 32 ​​fills the space between the auxiliary air guide 34 and the fixed air guide 31 with inert gas, and the wind pressure sensor 36 can detect the air pressure. When the air pressure fluctuates abnormally or is too low, a weld hole may appear at the welding point, and the product is unqualified. At this time, the turning member 25 can be driven to turn by rotating the motor 24, so that the steel workpiece 1 can fall from the turning slot 33 to the waste slot 26 for subsequent recycling.

[0068] If the airflow detection is normal, as the finished workpiece continues to move, the welding workpiece 19 will pass through the limit plate 28. When the welding workpiece 19 is tilted or skewed, the welding workpiece 19 will apply a horizontal force to the lower end of the limit plate 28, so that the upper end of the limit plate 28 presses the contact spring 27 until the pressure sensor provided at the upper end of the limit plate 28 is triggered. The turning motor 24 can then drive the flipping member 25 to flip, and the defective workpiece can be recovered.

[0069] The lower end of the clamping motor 13 is in contact with the side of the steel workpiece 1, and an elastic fixing part 14 is provided on the side of the clamping motor 13. The elastic fixing part 14 can make the lower end of the clamping motor 13 always in contact with the side of the steel workpiece 1, ensuring that the steel workpiece 1 will not shake during the welding process, and the welding quality is more stable.
