[0025] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the present utility model will be more complete and comprehensive, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0026] In addition, the drawings are only schematic illustrations of the embodiments of the present utility model and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0027] In this exemplary embodiment, an auxiliary fixture for welding is first provided. Referring to Figure 1 as shown, it includes:

[0028] A workbench 1, the workbench 1 is in the shape of a square groove, and several support legs are fixedly connected to the edge of the bottom plate of the workbench 1; Two mutually parallel horizontal pipes 2 are fixedly connected between two opposite inner walls of the workbench 1;

[0029] Moving tables 3, there are two moving tables 3, and they are sleeved side by side on the two horizontal pipes 2; A guide groove 4 is radially opened at the bottom of the moving table 3, and the cross section of the guide groove 4 is a right triangle; The same acute angles on the cross sections of the two guide grooves 4 are oppositely arranged;

[0030] As Figure 2As shown in the figure, a fixing frame 10 is fixedly connected to the top of the mobile station 3. The fixing frame 10 includes a back plate 19 fixedly connected to one end of the top of the mobile station 3, and a fixing plate 20 is fixedly connected to the other end of the back plate 19. The fixing plate 20 is parallel to the mobile station 3, and a pressing plate 12 is arranged between the fixing plate 20 and the mobile station 3. An adjusting bolt 11 is rotatably connected to the pressing plate 12, and the adjusting bolt 11 is threadedly connected to the fixing plate. The distance between the pressing plate 12 and the top of the mobile station 3 can be adjusted by the adjusting bolt 11, and the workpiece to be welded is clamped and fixed by pressing down the pressing plate.

[0031] A lead screw 7, one end of the lead screw 7 is fixedly connected to the bottom plate of the workbench 1 and is placed between two mobile stations 2; a handwheel 8 is engaged with the lead screw 7; a mounting frame 5, the mounting frame 5 is "U"-shaped, and rollers 6 are respectively installed at both ends of the mounting frame 5, as Figure 3 shown, the roller 6 is embedded in the guide groove 4; the mounting frame 5 is sleeved on the lead screw 7 and is placed between the bottom plate of the workbench 1 and the handwheel 8. By rotating the handwheel 8, the handwheel 8 moves relative to the lead screw 7. When the handwheel 8 abuts against the mounting frame 5, continuing to rotate the handwheel 8, the mounting frame 5 is subjected to the force of the handwheel 8, and the roller 6 rolls in the guide groove 4, thereby reducing the distance between the two mobile stations and realizing the adjustment of the distance between the workpieces to be welded on the mobile station 3.

[0032] The utility model can be used in cooperation with the adjusting bolt 11 arranged on the fixing frame 10 and the pressing plate 12 to clamp and fix the workpiece to be welded. By using the mounting frame 5 in cooperation with the roller 6 and the guide groove 4 inside the mobile station 3, the distance between the two mobile stations 3 can be adjusted, so that the distance between the two workpieces meets the welding conditions.

[0033] In some embodiments, a tension spring 9 is fixedly connected between the mobile station 3 and the inner wall of the workbench 1. The pulling force of the tension spring 9 and the force exerted on the mobile station 3 by the roller 6 in the guide groove 4 form a reaction force, making the mobile station 3 more stable.

[0034] In some embodiments, on the pressing plate 12, sliding rods 13 are respectively fixedly connected to both sides of the position where the adjusting bolt 11 is rotatably connected, and the sliding rods 13 penetrate through the fixing plate 20. The two sliding rods 13 penetrate through the fixing plate 20 and are fixedly connected to the pressing plate 12, so that when the pressing plate 12 is subjected to the force of the adjusting bolt 11, it will not displace and is more stable.

[0035] In some embodiments, cross bars 14 are respectively inserted through both ends of the horizontal pipe 2.

[0036] In some embodiments, a supporting device is connected to one end of the cross bar 14 away from the mobile station 3. When the workpiece to be welded is large, the workpiece to be welded is supported by the supporting device to prevent the workpiece to be welded from deforming.

[0037] In some embodiments, the support device includes a vertical rod 16 fixedly connected to the cross bar 14, and a top plate 17 is fixedly connected to the top end of the vertical rod 16. When the workpiece to be welded is large, the workpiece to be welded is supported by the top plate 17.

[0038] In some embodiments, as Figure 4 shown, the support device includes a sleeve 15 fixedly connected to the cross bar 14. A vertical rod 16 is inserted into the sleeve 15, and a top plate 17 is fixedly connected to the top end of the vertical rod 16; a fastening bolt 18 is threadedly connected to the sleeve 15, and the fastening bolt 18 abuts against the vertical rod 16. When the workpiece to be welded is large and has an irregular shape, by adjusting the fastening bolt 18, the support position of the top plate 17 is changed to prevent the workpiece to be welded from deforming.

[0039] The specific working process of an auxiliary fixture for welding according to the present utility model is as follows:

[0040] When two welding parts need to be welded, the workpiece to be welded is placed on the top of the moving table 2. By rotating the adjusting bolt 11, the pressing plate 12 is pressed down, and the workpiece to be welded is clamped and fixed by the pressing plate 12 and the top of the moving table 2; when the workpiece to be welded is large, the workpiece to be welded is supported by the support device to prevent the workpiece to be welded from deforming. By rotating the hand wheel 8, the hand wheel 8 moves relative to the lead screw 7. When the hand wheel 8 abuts against the mounting frame 5, by continuing to rotate the hand wheel 8, the mounting frame 5 is subjected to the acting force of the hand wheel 8, and the rollers 6 roll in the guide groove 4, thereby reducing the distance between the two moving tables, realizing the adjustment of the distance between the workpieces to be welded on the moving table 3. When the distance between the two workpieces to be welded meets the requirements, stop rotating the hand wheel 8. At this time, the staff can weld the two workpieces to be welded.

[0041] An auxiliary fixture for welding according to the present utility model can clamp and fix the workpiece to be welded by using the adjusting bolt provided on the fixed frame in cooperation with the pressing plate. By using the mounting frame in cooperation with the rollers and the guide groove inside the moving table, the distance between the two moving tables can be adjusted, so that the distance between the two workpieces meets the welding conditions. At the same time, with the cooperation of the cross bar, the vertical rod and the top plate, the workpiece to be welded can be supported and protected, thereby preventing the workpiece from deforming and improving the welding accuracy.
