Description

Technical Field

[0001] The utility model relates to the technical field of power battery processing, in particular to a power battery module tray positioning mechanism. Background Art

[0002] The power battery is the power source that provides power for tools, mostly referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. It is mainly different from the starter battery used to start the car engine, which mostly adopts valve-sealed lead-acid batteries, open-top tubular lead-acid batteries, and lithium iron phosphate batteries. The power battery usually includes an external battery shell and many battery cells installed inside. In order to connect these battery cells in series or in parallel, it is necessary to weld each electrode column of the battery cell to the corresponding busbar. Before welding the electrode column and the busbar, it is usually necessary to limit and fix the power battery to ensure that the welding position is accurate. Therefore, the welding table usually needs to use a fixed table top, which cannot be directly connected to the conveyor line, which will inevitably reduce the efficiency of the power battery transportation to the subsequent process.

[0003] For example, the utility model patent with authorization announcement number CN216990504U discloses a lifting and positioning mechanism for welding power battery busbars. This device uses the coarse positioning of the speed chain conveyor line and the fine positioning of the lifting and positioning assembly to not only accurately position the jig table, but also lift and support the jig table and detach it from the speed chain conveyor line to facilitate the subsequent welding and assembly of the busbars.

[0004] However, when the device is used in practice, it is unable to fine-tune the position of the positioning column. When the position of the positioning column deviates, it is difficult to accurately insert it into the positioning hole at the lower end of the power battery module tray, affecting the lifting of the power battery. At the same time, the device is not convenient for adjusting the support height of the rack table. For uneven ground, the rack table cannot be placed well, which reduces the practicability of the device and cannot meet the use requirements well. Utility Model Content

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 creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: Please refer to Figures 1 to 6 , a positioning mechanism for a power battery module tray, comprising: a frame table 1, on which an installation table 11 is slidably installed, a pair of slide rails 12 are installed on the installation table 11, a slide seat 13 is slidably installed on the slide rails 12, two groups of telescopic rods 10 are also installed on the installation table 11, each group of the telescopic rods 10 consists of four telescopic rods 10, a lifting seat 14 is installed on each group of the telescopic rods 10, a support column 15 is installed on each lifting seat 14, a positioning column 16 is also installed on each lifting seat 14, the positioning column 16 on the left lifting seat 14 is installed at the front left corner position of the upper end of the lifting seat 14, the positioning column 16 on the right lifting seat 14 is installed at the rear right corner position of the upper end of the lifting seat 14, a lifting electric cylinder 17 is also installed on the installation table 11, and the telescopic end of the lifting electric cylinder 17 is fixedly connected to the slide seat 13 through a connecting mechanism 4; an adjusting mechanism 3, installed on the frame table 1, for adjusting the position of the installation table 11; a supporting mechanism 2, installed at the lower end of the frame table 1, for adjusting the supporting height of the frame table 1.

[0024] The working principle of the present utility model: During specific use, first, the height of the feet of the frame table 1 is adjusted through the supporting mechanism 2, so that the frame table 1 is placed more stably on the ground. Subsequently, the position of the installation table 11 is adjusted through the adjusting mechanism 3. After the adjustment is completed, the installation table 11 is fixed to the frame table 1. Then, the lifting electric cylinder 17 is fixed to the slide seat 13 through the connecting mechanism 4, and the installation work can be completed, which is convenient for the subsequent positioning column 16 to be inserted into the jack at the lower end of the power battery module tray, completing the positioning work of the power battery tray and facilitating the subsequent lifting work, and can better meet the use requirements.

[0025] As a further solution, an installation groove 111 is formed in the slide seat 13 corresponding to the position of the lifting electric cylinder 17, and a plurality of lifting wedge-shaped seats 19 are installed on the upper end of the slide seat 13 corresponding to the position of each lifting seat 14, and a lifting roller 18 is installed at the lower end of each lifting seat 14 corresponding to the position of the lifting wedge-shaped seat 19.

[0026] The telescopic movement of the lifting electric cylinder 17 drives the sliding seat 13 to move along the slide rail 12, thereby moving the lifting wedge-shaped seat 19. When the lifting wedge-shaped seat 19 moves to the left, the lifting roller 18 rolls upward along the lifting wedge-shaped seat 19, thereby raising the lifting seat 14 and jacking up the power battery module tray. When the lifting wedge-shaped seat 19 moves to the right, the lifting roller 18 rolls downward along the lifting wedge-shaped seat 19, thereby lowering the lifting seat 14.

[0027] As a further solution, the connecting mechanism 4 includes a connecting piece 41 fixed to the telescopic end of the lifting electric cylinder 17. A connecting seat 42 is fixed on the sliding seat 13. A T-shaped groove 43 is formed in the connecting seat 42, and the plug at the end of the connecting piece 41 is inserted into the T-shaped groove 43.

[0028] When connecting, the T-shaped groove 43 of the connecting seat 42 is sleeved on the plug of the connecting piece 41. Subsequently, the connecting seat 42 and the sliding seat 13 are fixed by bolts, and the connection work can be completed.

[0029] As a further solution, the adjusting mechanism 3 includes a plurality of groups of adjusting seats 31 installed around the upper end of the frame table 1. An adjusting screw 32 is screwed on each adjusting seat 31. The end of the adjusting screw 32 penetrates through the adjusting seat 31 and is screwed with an adjusting nut 34. A plurality of fixing bolts 33 are also screwed on the mounting table 11.

[0030] The working principle of the adjusting mechanism 3 is as follows: during adjustment, the adjusting screw 32 is rotated to push, and at the same time, the end of the adjusting screw 32 pushes the mounting table 11 to move, thereby completing the fine adjustment of the position of the positioning column 16. After the adjustment is completed, the adjusting nut 34 is rotated to make it abut against the adjusting seat 31, so as to position the adjusting screw 32. Subsequently, the mounting table 11 and the frame table 1 are fixed by the fixing bolts 33.

[0031] As a further solution, the supporting mechanism 2 includes a supporting seat plate 21 installed at the lower end of the feet of the frame table 1. A supporting screw 22 is screwed on each supporting seat plate 21. A supporting base 23 is installed at the lower end of each supporting screw 22. A rotating nut 24 is also fixed at the upper end of the supporting screw 22. A locking nut 25 is also screwed on the supporting screw 22.

[0032] The working principle of the supporting mechanism 2 is as follows: the rotating nut 24 on the supporting screw 22 is rotated by a wrench, thereby driving the supporting screw 22 to rotate, so as to adjust the height of the feet of the frame table 1, facilitate the more stable placement of the frame table 1 on the ground, and improve the stability of the device. After the adjustment is completed, the locking nut 25 is rotated to make it abut against the supporting seat plate 21, thereby completing the fixing work of the supporting screw 22.
