Detailed Embodiments

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1-2As shown in the figure, a welding auxiliary fixture includes a fixer 2 and a workbench 1. The upper end of the workbench 1 is connected with a rotatable turntable 4 through a rotating shaft. An angle adjuster 3 is arranged on the upper end of the turntable 4. As Figure 3 shown, the angle adjuster 3 includes a first support block 301 and a second support block 304. The first support block 301 is fixedly connected with the turntable 4 through a disc 302. A scale ring 303 is arranged on the upper end of the disc 302. Scale lines representing angles are marked on the scale ring 303, and its scale range is 0 - 180°. The second support block 304 is located on the upper end of the disc 302. One end of the second support block 304 is connected with the disc 302 through a positioning bolt 307. When the positioning bolt 307 is loosened, the second support block 304 can rotate. When the positioning bolt 307 is tightened, the second support block 304 can be fixed. Fixers 2 for clamping workpieces are connected to the ends of both the first support block 301 and the second support block 304. The angle between the two fixers 2 can be adjusted through the angle adjuster 3, and the workpiece can be rotated through the turntable 4, increasing the convenience of welding.

[0024] A bracket 5 is arranged at the lower end of the workbench 1.

[0025] A rotating rod 401 is arranged on the side wall of the turntable 4, which can facilitate the rotation of the turntable 4.

[0026] A relief hole 306 is arranged on the second support block 304. A pointer 305 for indicating the scale is arranged in the relief hole 306. The pointer 305 is located in the middle of the second support block 304. The angle between the first support block 301 and the second support block 304 can be determined through the pointer 305.

[0027] As Figure 4 shown, the fixer 2 includes a support plate 207 connected with the angle adjuster 3. Blocks 201 and fixing blocks 204 are respectively arranged at both ends of the support plate 207. A lead screw 203 is connected inside the fixing block 204. Top blocks 202 and handles 205 are respectively arranged at both ends of the lead screw 203. By rotating the lead screw 203 through the handle 205, the top block 202 moves towards the block 201 to clamp the workpiece.

[0028] In addition, it should be noted that when the fixer 2 fixes the workpiece, the workpiece is perpendicular to the support plate 207. The two workpieces and the two fixers 2 form a quadrilateral. Therefore, the included angle between the two workpieces is 180° - the angle of the fixer 2.

[0029] Anti-slip pads are arranged on the side walls of both the top block 202 and the block 201, which not only increases the firmness of clamping but also prevents damage to the workpiece.

[0030] In order to improve stability, a support column 206 in contact with the workbench 1 is arranged at the lower end of the support plate 207.

[0031] As Figure 5 shown, during use, first adjust the angle of the angle adjuster 3 according to the requirements of the welding angle between the two workpieces (180° - the welding included angle between the two workpieces, that is, the angle of the angle adjuster 3). After adjustment, the workpieces are clamped and fixed by the fixer 2, and the welding joints of the two workpieces are butted. During the welding process, the orientation of the workpieces can be adjusted by rotating the turntable 4, saving the trouble of manual walking around the workpieces and increasing the convenience of welding.

[0032] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
