Description

Technical Field

[0001] This utility model relates to the field of blade battery casing processing technology, and in particular to a welding fixture for new energy blade battery casings. Background Technology

[0002] New energy batteries are mainly used in electric vehicles. Due to the complex operating environment, the safety performance requirements for these batteries are more stringent. The battery casing is a crucial component, serving as a seal. The blade battery casing used in new energy vehicles requires laser welding equipment during its manufacturing process to weld the casing.

[0003] Currently, a simple set of clamps is typically used to fix the blade battery casing for welding. The blade battery casing is clamped and fixed on both sides. There are few welding fixing points, which can easily lead to the blade battery casing being unstable and affect the quality of the welding. Utility Model Content

[0004] The purpose of this utility model is to address the deficiencies of the existing technology by providing a welding fixture for the casing of a new energy blade battery, thereby solving the problems mentioned in the background art.

[0005] A welding fixture for a new energy blade battery casing includes a workbench and a pressure application mechanism and a side positioning mechanism mounted on the workbench. The pressure application mechanism includes an electric cylinder one, a fixed column, a fixed plate, an electric cylinder two, and a pressure plate. The electric cylinder one and the fixed column are both mounted on the side of the workbench. The fixed plate is fixed to the output end of the electric cylinder one and moves up and down along the fixed column. The electric cylinder two is fixed to one side of the fixed plate. The pressure plate is fixed to the output end of the electric cylinder two and slides along the groove of the fixed plate.

[0006] The side positioning mechanism includes a base, an adjusting seat, a first screw, a third electric cylinder, a fixed head, a second screw, a movable seat, a third screw, and a pressure applying seat. There are two bases, which are distributed vertically on the worktable. The adjusting seat is adjustablely mounted on the base via the first screw and a nut. The fixed head is mounted at the output end of the third electric cylinder. The movable seat is adjustablely mounted on the fixed head via the second screw and a nut. The pressure applying seat is adjustablely mounted on the movable seat via the third screw and a nut. The base, adjusting seat, movable seat, and third screw define the four sides of the battery casing.

[0007] By adopting the above technical solution, the blade battery casing of different heights can be adapted and adjusted, and its stable positioning can be ensured.

[0008] Both the fixing plate and the pressure plate are set horizontally, and the pressure plate is distributed perpendicular to the fixing plate.

[0009] By adopting the above technical solution, pressure is applied to the upper surface of the blade battery casing to stabilize the blade battery casing.

[0010] The base and the adjustment seat have their ends facing the battery housing body in a vertically corresponding manner and are on the same vertical cross section.

[0011] By adopting the above technical solution, and ensuring its stable positioning.

[0012] The screw one has nuts rotating on both the upper surface of the base and the bottom surface of the worktable to stably limit the adjusting seat. The two sides of the fixed head have nuts rotating on the screw two to stably limit the moving seat. The upper and lower surfaces of the moving seat have nuts rotating on the screw three to stably limit the pressure seat.

[0013] By adopting the above technical solution, the corresponding upper and lower bases and adjustment seats, as well as the moving seat and pressure seat, are stably connected.

[0014] The movable seat and the pressure seat are vertically aligned and are designed as right-angled plates, with the thickness at both ends of the movable seat and the pressure seat being greater than the thickness at the middle.

[0015] By adopting the above technical solution, the other two sides of the blade battery casing are defined.

[0016] The beneficial effects of this utility model of welding fixture for new energy blade battery casing are:

[0017] The device can be adjusted according to the size specifications of the battery casing to ensure a stable fit and constraint on the side of the battery casing. Applying pressure from the top surface of the battery casing further prevents the battery casing from shaking and ensures that the position of the battery casing to be welded is stable when the battery casing is constrained. During this process, the position of the pressure plate on the upper surface of the battery casing can be controlled to ensure that the welding is not affected. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-2 A welding fixture for a new energy blade battery casing includes a workbench 1 and a pressure application mechanism and a side positioning mechanism installed on the workbench 1. The pressure application mechanism includes an electric cylinder 2, a fixed column 3, a fixed plate 4, an electric cylinder 5, and a pressure plate 6. The electric cylinder 2 and the fixed column 3 are both installed on the side of the workbench 1. The fixed plate 4 is fixed at the output end of the electric cylinder 2 and moves up and down along the fixed column 3. The electric cylinder 5 is fixed on one side of the fixed plate 4. The pressure plate 6 is fixed at the output end of the electric cylinder 5 and slides along the groove of the fixed plate 4.

[0023] The side positioning mechanism includes a base 7, an adjusting seat 8, a screw 1 9, an electric cylinder 3 10, a fixed head 11, a screw 2 12, a movable seat 13, a screw 3 14, and a pressure seat 15. There are two bases 7, which are distributed vertically on the worktable 1. The adjusting seat 8 is adjustablely mounted on the base 7 by the screw 1 9 and a nut. The fixed head 11 is mounted at the output end of the electric cylinder 3 10. The movable seat 13 is adjustablely mounted on the fixed head 11 by the screw 2 12 and a nut. The pressure seat 15 is adjustablely mounted on the movable seat 13 by the screw 3 14 and a nut. The base 7, adjusting seat 8, movable seat 13, and screw 3 14 limit the four sides of the battery housing body 16.

[0024] Based on the height of the battery housing body 16, the height of the adjusting seat 8 is adjusted in advance. Then, the nut on the screw 9 is rotated so that it is attached to the upper surface of the base 7. The nut at the lower end of the screw 9 is attached to the bottom surface of the workbench 1. The battery housing body 16 is pushed to the included angle of the two vertically arranged bases 7 as shown in the figure, so that the adjacent two sides of the battery housing body 16 are attached to the two bases 7 and the two adjusting seats 8.

[0025] Similarly, adjust the height of the pressure seat 15, then rotate the nut on the screw 14 to make it fit against the upper and lower surfaces of the movable seat 13. At this time, drive the electric cylinder 10 to push the fixed head 11 to move. The fixed head 11 drives the movable seat 13 to move synchronously through the screw 12. First, make the movable seat 13 and the pressure seat 15 contact one side of the battery housing body 16. Then loosen the nut on the screw 12 and push the movable seat 13 so that the other side of the movable seat 13 fits against the other side of the battery housing body 16. Then rotate the nut on the screw 12 to lock the screw 12. At this time, the four sides of the battery housing body 16 are limited by the base 7, the adjusting seat 8, the movable seat 13 and the screw 14.

[0026] Then, the electric cylinder 2 can be driven to pull the fixing plate 4 downwards, so that the pressure plate 6 is attached to the upper surface of the battery casing body 16. Pressure is applied from the upper surface of the battery casing body 16, and welding can be performed on the battery casing body 16 by external welding equipment. During this process, the electric cylinder 5 can be driven to push the pressure plate 6 to move, changing the position of the pressure plate 6 on the upper surface of the battery casing body 16 to facilitate welding. (It should be noted that because the pressure plate 6 applies pressure to the battery casing body 16, when adjusting the pressure plate 6, the electric cylinder 2 can be slightly driven to move upwards. After the pressure plate 6 is adjusted, the electric cylinder 2 can be driven to pull the pressure plate 6 downwards, so that pressure continues to be applied to the upper surface of the battery casing body 16 through the pressure plate 6.)

[0027] Both the fixing plate 4 and the pressure plate 6 are set in a horizontal position, and the pressure plate 6 is distributed perpendicular to the fixing plate 4; the control electric cylinder 5 can drive the pressure plate 6 to move and adjust the position of the pressure plate 6 so that the external welding equipment can perform welding processing on the battery casing body 16.

[0028] The base 7 and the adjusting seat 8 are vertically aligned with the end faces of the battery housing body 16 and are on the same vertical section. The base 7 fits and limits the lower end of the battery housing body 16, and the adjusting seat 8 fits and limits the upper end of the battery housing body 16. The adjusting seat 8 is adjustable on the base 7 by means of a screw 9 and a nut, which can limit the size of the blade battery housing of different specifications.

[0029] Screw 19 has nuts rotating on the upper surface of base 7 and the bottom surface of worktable 1 to stabilize and limit the adjusting seat 8. The two sides of the fixing head 11 have nuts rotating on screw 22 to stabilize and limit the moving seat 13. The upper and lower surfaces of the moving seat 13 have nuts rotating on screw 34 to stabilize and limit the pressure seat 15. The moving seat 13 can be adjusted horizontally by screw 22 and nuts. The position of the moving seat 13 can be adjusted according to the size of the battery housing body 16 so that after the electric cylinder 310 drives the fixing head 11 to move, the end faces of both ends of the moving seat 13 can fit and limit the side of the lower end of the battery housing body 16. Similarly, the pressure seat 15 moves with the moving seat 13 to fit and limit the side of the upper end of the battery housing body 16.

[0030] The movable seat 13 and the pressure seat 15 are vertically aligned and are designed as right-angled plates. The thickness of both ends of the movable seat 13 and the pressure seat 15 is greater than the thickness of the middle part, so that both ends of the movable seat 13 and the pressure seat 15 can be attached to the other two sides of the battery housing body 16.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
