Description

Technical Field

[0001] The invention relates to the field of titanium and titanium alloy electrode welding, in particular to a multi-head welding protection device. Background Art

[0002] The welding of titanium and titanium alloys has important applications in aviation, aerospace, chemical industry and high-end manufacturing, and the welding quality directly affects the performance and safety of the finished product. Titanium alloys have high requirements for protective gas during welding, especially the welding joints, which are easily contaminated by oxygen, nitrogen and other elements in the air, resulting in welding defects such as oxidation and porosity. In order to solve this problem, argon shielded welding is usually used, that is, an argon protection environment is provided for the welding point through a welding shield to avoid oxidation and interference from other gases.

[0003] First, in the traditional welding process, the protection time of each weld point usually needs to be maintained for more than 15 seconds to ensure that the weld point is not oxidized. However, the protection personnel need to fix the protective cover with one hand and hold the welding cap with the other hand, which makes the protection time of each weld point very fixed and labor-intensive. In addition, since the position and angle of the protective cover need to be adjusted manually, the manual operation process is cumbersome and inefficient. For mass production, this manual protection method one by one greatly limits the production speed. Secondly, due to the limited number of welding protective covers, and each welding operation requires the protection personnel to complete the protection of each weld point before welding the next weld point. Therefore, the welder often needs to wait for the protection personnel to complete the protection before continuing to weld the next weld point, which seriously affects the continuity of the welding operation. The existence of this waiting time not only wastes the time of the welding operation, but also leads to idle personnel and waste of resources.

[0004] Therefore, a solution is proposed. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 - Attachment Figure 7 The embodiment of the present invention provides a multi-head welding protection device, including a base 1, a U-shaped seat 10 is installed on one side of the top of the base 1, an electrode 2 to be welded is arranged on the other side of the top of the base 1, a driving motor 13 is installed on one side of the U-shaped seat 10, an output end of the driving motor 13 is fixedly connected to a driving screw 12, an external thread of the driving screw 12 is connected to a threaded seat 22, a first support plate 4 is detachably connected to the top of the threaded seat 22, a second support plate 5 is connected to the top of the first support plate 4 through a damping shaft 6, a plurality of mounting grooves 15 are opened on the inner side of the second support plate 5, a connecting sleeve 7 is installed on the inner wall of the mounting groove 15, a memory hose 8 is installed at the end of the connecting sleeve 7, a welding protection cover 9 is fixedly connected to one end of the memory hose 8, the driving screw 12 is driven to rotate by starting the driving motor 13, the threaded seat 22 is moved back and forth, the welding protection cover 9 is adsorbed on the outer surface of the electrode 2 to be welded, and the argon output device is injected into the memory hose 8 through the connecting sleeve 7, so as to output the welding point of the electrode 2 to be welded.

[0022] Specifically, the base 1 is the basic supporting part of the device, and other components are installed on the base to ensure the stability of the structure. The electrode to be welded 2 is the electrode that actually performs the electric welding operation during the welding process. The first support plate 4 and the second support plate 5: The first support plate 4 is connected to the second support plate 5 through the damping shaft 6. The function of the support plate is to support the welding protective cover 9, and through the movement of the driving screw 12, the welding protective cover 9 can be flexibly adjusted around the electrode to be welded 2. The inner side of the second support plate 5 is provided with a mounting groove 15 for installing the connecting sleeve 7. The connecting sleeve 7 can be connected to the memory hose 8, and one end of the memory hose 8 is fixedly connected to the welding protective cover 9. The memory hose 8 has good bending and fixation, and the angle of the welding protective cover 9 can be adjusted as needed, and it can be self-fixed in an appropriate position. The flexibility of the memory hose 8 enables the position of the welding protective cover 9 to be efficiently adjusted during the welding process, avoiding the cumbersome process of traditional manual adjustment. The argon cylinder 3 is connected to the connecting sleeve 7, and argon is injected into the inside of the welding protective cover 9 through the memory hose 8 to provide a protective atmosphere and reduce oxidation and pollution during welding. Argon gas protects the welding points and prevents pores or cracks from forming during the welding process.

[0023] After starting the drive motor 13, the motor drives the drive screw 12 to rotate, and the drive screw 12 pushes the threaded seat 22 to move forward and backward along the axis of the screw. The movement of the threaded seat 22 drives the first support plate 4 and the second support plate 5 to move synchronously, and adjusts the position of the welding protective cover 9 to adapt to different welding requirements. The argon cylinder 3 injects argon into the memory hose 8 through the connecting sleeve 7, and the argon in the hose is further transmitted to the welding protective cover 9 to provide a protective atmosphere for the welding area. The bending characteristics of the memory hose 8 enable the operator to flexibly adjust the angle of the welding protective cover 9 and fix it above the welding point, reducing the trouble of manual adjustment, and can replace manual fixing of the welding protective cover 9.

[0024] The second support plate 5 is also provided with a plurality of installation cavities 18 inside, which are connected with the installation groove 15. The movable rod 14 is slidably connected to the through hole outside the installation cavity 18, and one end of the movable rod 14 is fixedly connected to the moving plate 21. Two connecting rods 19 are rotatably installed outside the moving plate 21, and one end of the connecting rod 19 is rotatably connected to the clamping rod 16. The outside of the moving plate 21 is fixedly connected with a spring 20. The inner wall of the installation cavity 18 is provided with a limiting groove 17, and the outer side of the clamping rod 16 is slidably connected to the inner wall of the limiting groove 17. Two clamping grooves are provided on the outer side of the connecting sleeve 7, and the clamping grooves are plugged and matched with one end of the clamping rod 16. One end of the spring 20 is fixedly connected to the inner wall of the installation cavity 18, and the end of the movable rod 14 away from the moving plate 21 passes through the outer side of the second support plate 5 and extends to the outside thereof.

[0025] Specifically, when the operator presses the movable rod 14, the movable rod 14 drives the movable plate 21 to move inward, pushing the spring 20 to compress and causing the connecting rod 19 to swing. The swinging action of the connecting rod 19 causes the clamping rod 16 to slide along the limiting groove 17, thereby completing the installation of the connecting sleeve 7. The clamping rod 16 is inserted into the clamping groove of the connecting sleeve 7 to ensure that the connecting sleeve 7 is firmly installed. When the movable rod 14 is released, the elastic force of the spring 20 causes the movable plate 21 to reset, locking the clamping rod 16 in the clamping groove of the connecting sleeve 7, thereby completing the entire connection and installation process.

[0026] The threaded seat 22 is internally slidably connected with two guide rods 11, and both ends of the guide rods 11 are fixedly connected to the inner wall of the U-shaped seat 10. A plurality of argon gas cylinders 3 are also included, and the output ends of the argon gas cylinders 3 are connected to the inside of the connecting sleeve 7 through pipelines.

[0027] Specifically, the guide rod 11 is connected in the threaded seat 22 by sliding, ensuring that the threaded seat 22 moves accurately along the drive screw 12. The U-shaped seat 10 fixes the two ends of the guide rod 11, thereby ensuring that the threaded seat 22 does not tilt or get stuck during movement. The argon cylinder 3 is connected to the connecting sleeve 7 through a pipeline to ensure that argon can flow out of the cylinder and be transmitted to the welding protective cover 9 to provide the required protective atmosphere. These argon cylinders 3 are connected by pipelines to ensure a stable and continuous supply of gas.

[0028] It also includes a real-time welding detection system, which is used to realize real-time monitoring, control and adjustment of the welding process. The real-time welding detection system includes: Welding quality monitoring module, which is used to monitor key parameters of the welding process in real time, including temperature, welding current, voltage, welding time and welding speed; The welding quality monitoring module includes: Temperature sensor, which is used to detect the temperature of the welding area in real time to ensure that the welding point does not overheat or oxidize; Current and voltage sensors, which are used to monitor the arc current and voltage during welding to ensure they are within set ranges; Gas flow sensor, which is used to monitor the flow of argon gas to ensure adequate protection of the weld from oxidation.

[0029] Real-time data collection and analysis module, which is used to organize and analyze the received data; Automatic adjustment control module, which automatically adjusts the current, voltage, gas flow and other parameters during the welding process; The feedback control and indication module is used to provide workers with real-time information and status of the welding process, including whether the welding temperature, current and voltage are within a safe range.

[0030] Specifically, the temperature sensor is used to monitor the temperature of the welding area in real time to ensure that the temperature of the solder joint is within the appropriate range. Excessive temperature may cause the solder joint to overheat, resulting in oxidation, welding defects or damage to the material. During the welding process, temperature control is critical. The temperature sensor can monitor and transmit real-time temperature data to help the system determine whether the welding process is normal and avoid poor welding quality due to excessive temperature.

[0031] The current and voltage must be kept within the set range to ensure arc stability during welding. Too high a current may cause overheating or melt too much material, while too low a voltage may result in an unstable arc or poor welding results. Sensors can detect these parameters in real time and transmit the data to the control system.

[0032] Gas flow sensors are used to protect the stability of gas flow, which is essential to prevent oxidation and contamination during welding. Insufficient gas flow may cause the weld to be exposed to air, which in turn causes oxidation and affects the quality of welding. Gas flow sensors provide real-time feedback on gas flow to ensure that the flow of shielding gas during welding meets the predetermined requirements.

[0033] By analyzing real-time data, the system can detect any anomalies or deviations during the welding process. Data analysis can help the system determine whether the welding meets the predetermined quality standards, identify potential problems, and provide a basis for subsequent adjustments.

[0034] The real-time monitoring system detects abnormal conditions and prompts the operator to make timely adjustments through sound and light alarms or display screens.

[0035] An integrated display screen is installed outside the welding protection cover 9, which is used to display real-time information such as welding status, temperature, current, etc.

[0036] Working principle: When the device is used, the driving motor 13 is started to drive the driving screw 12 to rotate, thereby driving the threaded seat 22 to move forward and backward along the outer wall of the driving screw 12, thereby driving the first support plate 4 and the second support plate 5 to move synchronously, thereby flexibly adjusting the position of the welding protection cover 9; At this time, the movable rod 14 is pressed inward to drive the movable plate 21 to move synchronously. As the movable plate 21 moves, the spring 20 is compressed on the one hand, and one end of the connecting rod 19 is swung on the other hand. Under the traction force of the connecting rod 19, the clamping rod 16 is driven to move along the inner wall of the limiting groove 17. At this time, the connecting sleeve 7 is inserted into the installation groove 15, and the movable rod 14 is released. Under the elastic force of the spring 20, the movable plate 21 is reset, and one end of the clamping rod 16 is clamped into the clamping groove on the outer wall of the connecting sleeve 7 to achieve rapid installation of the connecting sleeve 7. The output pipe of the argon cylinder 3 is installed on the top of the connecting sleeve 7, and the argon gas generated by the argon cylinder 3 is transmitted to the memory hose 8. At this time, the welding protection cover 9 is firmly adhered to the outer surface of the electrode 2 to be welded by adsorption to output the welding point. When protecting the welding point, only one person is needed to adjust the position and angle of the memory hose 8. Since the memory hose 8 can be bent at any angle and can be fixed on the welding point by itself, it replaces the manual fixing of the welding protection cover 9. When welding the next welding point, the remaining support plates are used in sequence for protection. This eliminates the need to wait for protection time during welding and saves one person, which greatly saves human resources and reduces the burden on operators.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
