[0002] Assembly welding positioning refers to positioning the parts to be welded together as required and fixing them on the tooling with suitable fixtures. Positioning welding is a temporary method to fix the parts in the appropriate position and position until the final welding is completed;

[0003] Currently, during welding assembly, the operator clamps the workpiece to be welded on the fixed fixture with a clamp column, and then holds the butt-welded workpiece for assembly welding. This method is suitable for welding small workpieces and welding with low assembly precision requirements. However, when large workpieces need to be welded, the operator holds the butt-welded workpiece in one hand and the welding tool in the other hand. This welding method will cause the precision of the welded workpiece to be unstable, thereby resulting in the appearance of unqualified products, which increases the risk of unqualified products. In addition, the existing butt-welded workpiece clamping method can only fix butt-welded workpieces of one size, so it needs to be improved. Utility Model Content

[0021] A slide groove 7 is provided on the fixed base 1 , and a fixed block 8 is provided on the sliding plate 2 . The fixed block 8 is slidably connected to the slide groove 7 .

[0022] The driving mechanism comprises a driving motor 3 mounted on a fixed base 1 , the output end of the driving motor 3 is drivingly connected to a rotating shaft 4 , a gear 5 is mounted on the rotating shaft 4 , and the gear 5 meshes with a rack mounted on the sliding plate 2 .

[0023] The shape of the sliding plate 2 is "L"-shaped, and the shape of the fixed base 1 is "C"-shaped.

[0024] The above scheme is adopted: through the cooperation between the sliding plate 2 and the gear 5, the rack is meshed with the gear 5, so that when the driving motor 3 rotates, it drives the sliding plate 2 and the fixed block 8 to move, so that the first workpiece and the second workpiece are accurately docked, and through the cooperation between the slide groove 7 and the fixed block 8, the inner wall of the slide groove 7 is smooth, so that the friction force is reduced when the slide groove 7 moves, and the movable connection limits the sliding plate 2, so that the gear 5 is more stable when driving the sliding plate 2 to move.

[0025] The first clamp includes: a fixed plate 6, one end of the fixed plate 6 is connected to the fixed base 1, and the other end of the fixed plate 6 is provided with a plurality of symmetrically arranged movable grooves, and the specific number of movable grooves is determined according to the structure of the clamped workpiece. In this embodiment, a total of four movable grooves are provided, and each movable groove is provided with a movable block 9 that matches the movable groove and is slidably connected to the movable groove. The four movable blocks 9 enclose a clamping space for clamping the first workpiece.

[0026] The moving block 9 is provided with a group of transverse holes penetrating the opposite sides of the moving block 9 and longitudinal holes communicating with the transverse holes. The inner walls of the transverse holes and the longitudinal holes are smooth for easy sliding. A group of moving plates 10 are provided in the longitudinal holes. A spring telescopic rod 11 and a first spring 14 are installed on the side of each moving plate 10 away from the other moving plate 10. A rectangular block 12 is installed on the side of the spring telescopic rod 11 away from the moving plate 10. The end of the first spring 14 away from the moving plate 10 is connected to the moving block 9. The side wall of the moving groove is provided with a plurality of groups of grooves 13 arranged opposite to each other. The size of the grooves 13 matches the rectangular block 12. The length of the rectangular block 12 is the same as the inner diameter of the groove 13. After the moving block 9 passes through the transverse hole, it is embedded in the groove 13 to fix the relative position of the moving block 9 and the moving groove.

[0027] The structure of the second clamp is the same as that of the first clamp.

[0028] The above scheme is adopted: through the cooperation of the moving block 9 and the moving plate 10, the two moving plates 10 are pinched, and the two moving plates 10 drive the spring telescopic rod 11, the rectangular block 12 and the first spring 14 to move towards each other, so that the rectangular block 12 and the groove 13 are no longer clamped, and then the workpiece to be welded is fixed between the four moving blocks 9, and then the moving plate 10 is released, and the first spring 14 drives the moving plate 10, the spring telescopic rod 11 and the rectangular block 12 to move away from each other, so that the rectangular block 12 and the groove 13 are clamped, thereby completing the fixation of the workpiece to be welded, starting the drive motor 3, and the drive motor 3 drives the rotating shaft 4 and the gear 5 to rotate, so that the first welded workpiece and the second welded workpiece are precisely combined.

[0029] The above scheme is adopted: through the cooperation between the moving block 9 and the moving plate 10, the connecting parts on both sides of the moving plate 10 are movably connected with the transverse holes and the longitudinal holes of the moving block 9, so that a limit is generated when the moving plate 10 moves toward each other, thereby making the moving plate 10 more stable, and the inner walls of the transverse holes and the longitudinal holes of the moving block 9 are smooth, so that the friction of the moving plate 10 is reduced when it moves, and through the limitation of the shapes of the fixed base 1 and the sliding plate 2, the "L" shape of the sliding plate 2 enables the gear 5 to better adjust the docking welding workpiece when driving the clamp to move, and then perform overall adjustment, and through the cooperation between the rectangular block 12 and the groove 13, the length value of the rectangular block 12 is the same as the inner diameter value of the groove 13, so that the rectangular block 12 can be snapped into the inner wall of the groove 13, thereby clamping and fixing welding workpieces of different sizes.

[0030] The working principle and use process of this utility model:

[0031] When in use, the operator first pinches the moving plates 10, so that the two moving plates 10 drive the spring telescopic rod 11, the rectangular block 12 and the first spring 14 to move toward each other, so that the rectangular block 12 and the groove 13 are no longer clamped, and then the welded workpiece is fixed between the four moving plates 10. After clamping, the two moving plates 10 are released, and the first spring 14 drives the spring telescopic rod 11, the moving plates 10 and the rectangular block 12 to clamp the groove 13, so as to complete the fixation of the welded workpiece, and repeat the above operation to complete the fixation of the butt welded workpiece;

[0032] Then, the drive motor 3 is started, and the drive motor 3 drives the rotating shaft 4 and the gear 5 to rotate, so as to adjust the position of the docking welding workpiece, so as to achieve a precise combination with the welding workpiece, so that the operator can better complete the welding work and achieve a better effect of reducing the occurrence of unqualified products.
