[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. In the processing of metal steel plates, workers need to use welding clamping devices to connect the steel plates. The application of welding technology now involves almost all industrial fields such as energy, transportation, aerospace, construction engineering, electrical engineering, microelectronics, etc., and is widely used. When welding workpieces, it is necessary to use a clamping device to clamp and position the two workpieces to be welded to facilitate precise docking.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A plug-in slot 101 is provided in the middle of the adjusting stand 1. Axle seats 102 are fixedly welded at the front and rear ends of the adjusting stand 1 near the plug-in slot 101. A shaft rod 103 is fixedly installed between the front and rear axle seats 102. Two pairs of hydraulic cylinders 4 are provided and are rotatably installed between the bottoms of the two welding table plates 3 and the adjusting stand 1. When in use, the welding table plates 3 are driven to move by the telescopic action of the hydraulic cylinders 4, and the two welding table plates 3 move to form different angles.

[0024] A mounting bracket 306 is fixedly welded to one side of the top of the welding table 3 near the plug-in slot 101, and a second slide slot 307 is opened on the mounting bracket 306. Two sliders 308 are symmetrically slidably installed on the second slide slot 307. An adjusting screw 309 is threadedly installed at the center of the slider 308. A pressure plate 310 is rotatably installed at the bottom end of the adjusting screw 309 and a second rotating hand wheel 311 is fixedly welded to the top end. When in use, the distance between the two sliders 308 can be adjusted by moving the slider 308 to achieve the purpose of clamping and fixing plates of different widths.

[0025] The waste box 2 is inserted into the plug-in slot 101, and a pull-out handle is provided at the front end of the waste box 2. When in use, the waste chips generated during the welding process will fall into the waste box 2 through the plug-in slot 101 for collection, and the waste box 2 can be pulled out by the pull-out handle. The processing personnel can weld the back of the panel through the plug-in slot 101, and double-sided welding improves the welding strength.

[0026] There are two welding plates 3 which are rotatably mounted on two shafts 103 respectively. The two welding plates 3 are mirror-imaged with the insertion slot 101 as the central axis. When in use, the two welding plates 3 are pushed to rotate in opposite directions on the shaft 103 to tilt to form a specific angle.

[0027] Two support columns 301 are fixedly installed on the top of the welding table 3 away from the plug-in slot 101. When the two support columns 301 contact the top of the adjustment platform 1, the welding table 3 is in a horizontal state. When in use, the supporting effect of the support columns 301 is used to make the welding table 3 horizontal, thereby improving the accuracy of panel welding, and the support columns 301 can also play a buffering role.

[0028] A first horizontal slide groove 302 is provided on the top of the welding table 3, and a driving screw 303 is rotatably installed in the first slide groove 302, and one end of the driving screw 303 extends to the outside of the welding table 3 and is fixedly welded with a first rotating handwheel 304. A positioning push plate 305 is slidably installed in the first slide groove 302, and the positioning push plate 305 is threadedly connected to the driving screw 303. The positioning push plate 305 is arranged on the top of the welding table 3 away from the plug-in slot 101. When in use, the driving screw 303 is rotated by the first rotating handwheel 304, and the driving screw 303 rotates to drive the positioning push plate 305 to move to achieve the purpose of accurately positioning plates of different lengths.

[0029] A non-slip rubber pad is fixedly bonded to the bottom of the pressing plate 310 and a plurality of non-slip contacts are integrally formed on the non-slip rubber pad. When in use, the pressing plate 310 presses the plate to be welded to increase the friction through the non-slip rubber pad, thereby improving the firmness of the fixed clamping.

[0030] Specifically, when it is necessary to weld the plates horizontally, it is only necessary to place the two plates on the welding table 3, and one end of the plates is against the positioning push plate 305, and the driving screw 303 is rotated by the first rotating hand wheel 304, and the driving screw 303 is rotated to drive the positioning push plate 305 to move, and the positioning push plate 305 moves to push the plates to move until the two plates are in contact, and then the adjusting screw 309 is rotated by the second rotating hand wheel 311, and the adjusting screw 309 is rotated and moved downward to push the pressure plate 310 to press the plates to be welded, and the spacing between the two sliders 308 is adjusted by moving the slider 308 to achieve the purpose of clamping and fixing plates of different widths, and then quick butt welding can be performed. When it is necessary to weld the plates at an inclined angle, it is only necessary to control the length of the hydraulic cylinder 4 through the external control terminal, and drive the welding table 3 to move through the telescopic action of the hydraulic cylinder 4, and the two welding table plates 3 move to form different angles, and then fine-tune the positions of the two plates to meet the purpose of welding at different inclination angles.
