Description

Technical Field

[0001] The utility model belongs to the technical field of clamping devices for square tube welding, in particular to an auxiliary clamping device for square tube welding with quick clamping. Background Art

[0002] The quick-clamping auxiliary clamping device for square tube welding is a device used to fix the workpiece and provide pressure when helping to weld the square tube. This device clamps the two ends of the square tube to ensure that the position of the square tube remains stable during welding. At the same time, the auxiliary clamping device can also provide additional pressure to ensure close contact between the workpieces during welding, thereby ensuring the welding quality. This device is usually designed to facilitate quick installation and disassembly to improve work efficiency and convenience. During the welding process, the auxiliary clamping device can effectively reduce the risk of welding deformation and warping, and can also improve the welding speed and quality.

[0003] Most of the quick-clamping auxiliary clamping devices for square tube welding on the market still have the following problems when used:

[0004] 1. After the two square tubes are welded, the traditional quick-clamping auxiliary clamping device for square tube welding needs to be clamped for a period of time to completely cool the two square tubes so that the two square tubes can be completely fixed together. However, waiting for them to cool naturally is a waste of time, resulting in a decrease in welding efficiency. At the same time, it will also produce odors that are harmful to health during welding, which may cause harm to the health of the workers;

[0005] 2. Most quick-clamping square tube welding auxiliary clamping devices need to recover the clamping plate and the clamping device separately after use and put them together. Each time they are reused, the clamping device and the clamping plate device need to be taken out separately, which makes installation and use more cumbersome. Utility Model Content

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of a quick-clamping square tube welding auxiliary clamping device in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, the utility model is a quick-clamping auxiliary clamping device for square tube welding, comprising a clamping frame 1, a mounting plate 15 is fixedly connected inside the clamping frame 1, a second support rod 13 is fixedly connected to the bottom of the mounting plate 15, a second foot pad 14 is fixedly connected to the bottom of the second support rod 13, a blowing device 16 is fixedly connected to the top of the mounting plate 15, an external frame 17 is fixedly connected to the inside of the blowing device 16, a small motor 19 is fixedly connected to the inside of the external frame 17, a fan 18 is connected to the bottom of the small motor 19 through a rotating shaft, the fan 18 is driven to rotate by the small motor 19, so that the fan 18 generates wind force, continuously blows air to the welding area, accelerates the cooling time of the welding place, and makes the welding position of the two square tubes can be quickly finalized, and at the same time can also dispel the odor emitted by heat welding, avoids harm to the body of the staff, and accelerates the welding efficiency.

[0029] The top of the clamping frame 1 is fixedly connected with a mounting block 20, a magnetic groove 12 is opened inside the mounting block 20, a magnetic block 11 is magnetically connected inside the magnetic groove 12, and a rear clamping plate 4 is fixedly connected to the back of the magnetic block 11. By fixing the mounting block 20 on the top of the clamping frame 1 and opening a magnetic groove 12 inside the mounting block 20, the magnetic groove 12 can be connected to the magnetic block 11 fixedly connected to the surface of the rear clamping plate 4, thereby combining the clamping plate mechanism and the clamping structure together and storing them, there is no need to take them separately the next time they are used, which is more convenient to use.

[0030] A first support rod 2 is fixedly connected to the bottom of the clamping frame 1, and a first foot pad 3 is fixedly connected to the bottom of the first support rod 2. By fixing the first support rod 2 to the bottom of the clamping frame 1 and fixing the first foot pad 3 to the bottom of the first support rod 2, the device can be stabilized on a required plane. At the same time, the foot pad at the bottom also has an anti-slip effect to prevent it from sliding during the clamping process and causing the square tube to be misaligned, and the anti-slip effect is good.

[0031] The top of the clamping frame 1 is fixedly connected with a vertical rod 6, and the side of the vertical rod 6 is fixedly connected with a cross rod 7.
