[0067] It is understandable that the rail fast welding device and method of the present invention have significant advantages in improving production efficiency, ensuring welding quality and reducing operation difficulty. By implementing the present invention, the overall technical level of rail welding can be effectively improved to meet the needs of modern industrial production.

[0072] Specifically, the clamping assembly 110 includes:

[0073] Support frames are provided at both ends of the roller 101. The support frames are located below the roller 101 and abut against the roller 101. The support frames are used to support the roller 101;

[0074] There are four substrates 111, and every two substrates 111 form a group of substrates. Each group of substrates is arranged along the first direction, and each group of substrates is located on one side of the roller 101. An area for placing the guide rail 140 is arranged in the middle of each group of substrates. The two ends of the substrates 111 are respectively connected to the support frames located at the two ends of the roller 101; wherein the first direction is perpendicular to the axial direction of the roller 101, and is parallel to the extension direction of the guide rail 140;

[0080] Specifically, the transmission components include:

[0081] The movable frame 121 is located at both ends of the welding frame 100, and the top of the movable frame 121 is connected to the welding assembly;

[0082] The ball screw 122 is located at the bottom of the welding frame 100. The ball screw 122 includes a screw rod and a nut. Both sides of the nut are connected to the bottom end of the moving frame 121.

[0091] It can be seen that the welding frame 100 assembly fully considers the flexibility and precision requirements of the welding operation. The setting of the support rod 131 provides a solid support for the welding frame 100, ensuring the stability of the welding operation; the combined design of the slide bar 132 and the slide 133 enables the welding gun 134 to be accurately positioned and moved in the vertical direction, so as to adapt to the welding requirements of different heights and angles; the introduction of the telescopic cylinder makes the movement of the welding gun 134 more flexible, and can be quickly adjusted to the required position, improving the efficiency of the welding operation; the telescopic function of the welding gun 134 makes the welding operation more precise, and can perform detailed welding operations on different parts of the track. Through the control of the telescopic cylinder, the welding gun 134 can be easily adjusted to the optimal welding angle to ensure the quality of the welding joint. The rapid response and positioning ability of the welding gun 134 greatly reduces the pause time during the welding process, further improving production efficiency.

[0092] Specifically, the control system includes:

[0093] A control cabinet, located outside the welding frame 100;

[0098] Specifically, the control system also includes:

[0099] Limit switches: limit switches are provided at both ends of the mobile frame 121. The limit switches are used to be triggered when the mobile frame 121 moves to the limit position and send a signal to the control system;

[0100] The temperature sensor is arranged on the welding gun 134 and is used to monitor the temperature of the welding gun 134 in real time. When the temperature of the welding gun 134 exceeds a preset value, the temperature sensor sends a signal to the control system.

The setting of the limit switch ensures that the mobile frame 121 can stop in time when it reaches the predetermined position, avoiding equipment damage or safety accidents that may be caused by excessive movement; the real-time monitoring function of the temperature sensor ensures that the welding gun 134 works within a safe temperature range to prevent overheating from affecting the welding quality and equipment life. When the limit switch or temperature sensor sends an alarm signal, the control system will immediately respond and take corresponding protective measures, such as stopping the movement of the mobile frame 121 or adjusting the temperature of the welding gun 134, thereby ensuring the stability and safety of the entire welding process.

[0102] Specifically, the guide rail 140 is 15 meters long.

The length of 15 meters provides a sufficient range of movement for the welding assembly, which can meet the welding needs of workpieces of different lengths, thereby improving the applicability and flexibility of the equipment. At the same time, the stability and precision of the guide rail 140 ensure the stability and accuracy of the welding assembly during long-distance movement, ensuring the consistency of welding quality.
