Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1As shown, a welding auxiliary device for plate 6 includes a welding table 1, a support platform 101 is provided at the upper middle part of the welding table 1, and support platforms 2 are provided on both sides of the support platform 101 that slide in cooperation with the welding table 1. Plate 6 is placed on the upper end of the support platform 101 and the support platforms 2, and the joint of the two plates 6 is located at the upper end of the support platform 101.

[0025] A pressure plate 3 is connected to one side of the welding table 1, such as... Figure 4 As shown, the pressure plate component 3 includes a support rod 301 connected to the welding table 1. The upper end of the support rod 301 is connected to a swing arm 303 via a pivot 302. The end of the swing arm 303 is connected to a threaded rod 305. The upper end of the threaded rod 305 is provided with a gripping rod 304, and the lower end of the threaded rod 305 is provided with a pressing block 306 for pressing the plate 6. The pressing block 306 is rotated to the top of the support table 101 to press and fix the end of the plate 6, ensuring the flatness of the joint of the two plates 6 and preventing the plate 6 from sliding.

[0026] Two pressure plates 3 are provided on each side of the welding table 1, which can press the two plates 6 respectively. Each plate 6 is pressed and fixed by two pressure blocks 306.

[0027] The maximum distance between the pressure block 306 and the support platform 101 is not less than 5cm, which can be used for welding and fixing of plates 6 of most thicknesses.

[0028] The upper end of the welding table 1 is connected to a guide rod 5 and a lead screw 4. One end is connected to the support platform 101, and the other end is connected to the welding table 1 via a support block. One end of the lead screw 4 is equipped with a handle 401, such as... Figure 2 As shown, the lower end of the support platform 2 is provided with a sliding sleeve 201 that cooperates with the guide rod 5 and a nut seat 202 that cooperates with the lead screw 4. By rotating the lead screw 4 through the handle 401, the support platform 2 can be driven to slide, thereby realizing the adjustment of the distance between the support platform 2 and the support platform 101, which can meet the needs of supporting plates 6 of different lengths.

[0029] The support platform 101 has a groove 102 in the middle, and a positioning block 103 is provided in the groove 102, such as... Figure 3 As shown, the positioning block 103 is equipped with positioning bolts 104, which are fixed to the bottom of the slide groove 102. The positioning block 103 can position both sides of the plate 6. At the same time, the joint of the plate 6 is located above the slide groove 102, making way for the welding position.

[0030] The two ends of the slide 102 are open, which facilitates the disassembly of the positioning block 103 and the cleaning of welding slag inside the slide 102.

[0031] The upper part of the positioning block 103 extends at least 2cm beyond the support platform 101, which can stably position the plate 6.

[0032] like Figure 5 As shown, in use, first place the plate 6 on the upper end of the support plate and the support table 101. The joint of the two plates 6 is located above the slide groove 102. After the two plates 6 are joined, the two sides of the plate 6 are positioned by the positioning block 103. Then, rotate the swing arm 303 so that the pressure block 306 presses and fixes the ends of the plate 6, thus achieving the positioning of the two plates 6. Welding can be carried out after positioning is completed.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
