DETAILED DESCRIPTION

[0025] 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.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a battery box welding positioning tool, including a stand 1, a ring frame 2 is arranged on the stand 1, an inner support component 3 for supporting the inside of the battery box is arranged on the stand 1, a lifting component 4 for lifting the inner support component 3 and the battery box upward is arranged on the stand 1, an outer clamping component 5 for clamping the outside of the battery box is arranged on the ring frame 2, and a welding component 6 for welding the battery box is also arranged on the ring frame 2, and the inner support component 3, the outer clamping component 5 and the welding component 6 are all adjustable.

[0028] Among them, the inner support component 3 includes a placement seat 31 and an inner support plate 32 located on the outside of the placement seat 31, a two-way screw rod 33 rotatably installed in the placement seat 31 and an internal thread block 34 threadedly sleeved on the outside of the two-way screw rod 33, a connecting rod 35 is also provided between the internal thread block 34 and the inner support plate 32, and the internal thread block 34 also slides in the placement seat 31, and there are two internal thread blocks 34 on a two-way screw rod 33, and the two internal thread blocks 34 are hinged with connecting rods 35, and the other ends of the two connecting rods 35 are hinged to the inner side of the inner support plate 32 at the same time. In this embodiment, the sliding of the internal thread block 34 in the placement seat 31 ensures the stability of the movement, and also ensures the stability of the inner support plate 32. The spacing difference generated after the two internal thread blocks 34 move is then driven to move the inner support plate 32 under the action of the connecting rod 35. This structure is stable and reliable. In order to further improve the stability of the inner support plate 32, a guide rod can be provided on the inner support plate 32, and the guide rod slides in the placement seat 31.

[0029] Among them, the inner support plate 32 and the bidirectional screw rod 33 are distributed in multiple groups on multiple sides of the placement seat 31. The inner support component 3 also includes a servo motor 36 fixed inside the placement seat 31. Bevel gears 37 are provided between the multiple bidirectional screw rods 33 and the output ends of the bidirectional screw rods 33 and the servo motor 36. The multiple bidirectional screw rods 33 are linked through the bevel gears 37 and driven by the servo motor 36. The bevel gears 37 provided in this embodiment can ensure the transmission effect while changing the transmission direction, and ensure the synchronous transmission between the multiple bidirectional screw rods 33. After the multiple bidirectional screw rods 33 rotate, they all drive the internal thread blocks 34 at their upper ends to move inward or outward at the same time, ensuring the synchronous movement of the inner support plate 32, thereby reliably supporting the inside of the battery.

[0030] Among them, the outer clamping component 5 includes an outer clamping plate 51 and a guide plate 52 formed at the bottom of the outer clamping plate 51, and a linear slide rail 53 arranged between the outer clamping plate 51 and the ring frame 2. A clamping cylinder 54 is fixed on the ring frame 2. The output end of the clamping cylinder 54 is fixed to the inner side of the outer clamping plate 51. The outer clamping plate 51 moves horizontally under the action of the linear slide rail 53. In this embodiment, the guide plate 52 plays a guiding role, which is convenient for the shaping of the battery box before welding. Through multiple outer clamping plates 51, multiple surfaces of the outside of the battery box are squeezed, thereby ensuring the stability of the battery box before welding, and then ensuring the quality of the battery box after welding.

[0031] Among them, the welding component 6 includes a laser welding gun 61 and a welding cylinder 62 fixed on the outside of the ring frame 2. A second guide rod 63 is fixed on the laser welding gun 61 and is fixed to the output end of the welding cylinder 62. The second guide rod 63 also penetrates and slides in the ring frame 2. In this embodiment, the second guide rod 63 improves the structural reliability of the laser welding gun 61 during adjustment and use. The laser welding gun 61 is facing the position where the battery box needs a welder.

[0032] Among them, the lifting component 4 includes a first guide rod 41 fixed to the bottom of the placement seat 31 and a lifting cylinder 42 fixed on the vertical frame 1. The output end of the lifting cylinder 42 is upward and fixed to the bottom of the placement seat 31. The first guide rod 41 also vertically penetrates and slides in the vertical frame 1. In this embodiment, the lifting cylinder 42 can push the battery box placed on the inner support component 3 out from the upper end of the ring frame 2 to facilitate the removal of the battery box after welding.

[0033] It can be understood that the battery box is first shaped by the inner support plate 32 and the outer clamping plate 51, and then the welding component 6 is welded at the position where the battery box needs to be welded by lifting the lifting component 4, thereby ensuring the structural stability of the battery box and the welding quality. Secondly, the inner support plate 32, the outer clamping plate 51 and the welding component 6 can also be adjusted according to the size of the battery box and reliable welding can be performed, which has good adaptability and practicality.

[0034] A specific application of this embodiment is: Figure 1 As shown, the cut and formed plate is now bent, and after bending, the battery box is placed downward and sleeved on the upper end of the inner support component 3. At this time, the lifting cylinder 42 drives the inner support component 3 and the battery box placed on the upper end to rise, and the outer part of the battery box is attached to the inner side of the outer clamping plate 51 and continues to move upward. After the battery passes through the outer clamping component 5, the welding component 6 performs welding work at this time. After the welding is completed, the battery box can be directly taken out from the top of the device;

[0035] The adjustment of the inner support member 3 is as follows: according to the inner size of the battery box, the servo motor 36 is driven to drive multiple bidirectional screws 33 to rotate synchronously through the bevel gear 37, and the internal thread block 34 moves horizontally through the spiral of the bidirectional screw 33. During the movement, the distance between the inner support plate 32 and the placement seat 31 is changed through the connecting rod 35, and multiple inner support plates 32 move outward or inward synchronously;

[0036] Adjustment of the outer clamping member 5: The clamping cylinder 54 drives the outer clamping plate 51 to move horizontally, and the outer clamping plate 51 moves on the ring frame 2 through the linear slide rail 53 until the outer side of the outer clamping plate 51 fits with the outer wall of the battery box;

[0037] Use of welding component 6: When the position where the battery box needs to be welded reaches the front end of the laser welding gun 61, the welding cylinder 62 pushes the laser welding gun 61 forward, and the laser welding gun 61 works to weld. During the movement of the laser welding gun 61, the second guide rod 63 follows and moves in the ring frame 2.
