[0002] New energy battery casings are used to enclose the battery's main components. They serve as a protective device to minimize the impact of external environmental factors on the battery's internal structure and prevent leakage of internal components. During the production and processing of new energy battery casings, the mounting holes at the edges are often weak. Therefore, a split collar is typically press-fitted into the hole to increase its strength.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-8 The battery shell pressing tool comprises a workbench 1 for placing the battery shell 2. The workbench 1 comprises a table top and legs supporting the table top. A plurality of universal wheels are fixedly connected to the bottom of the legs, and the plurality of universal wheels are provided with a braking mechanism.

[0030] The upper surface of the workbench 1 is provided with a plurality of positioning components 3 for positioning the inner edge of the battery shell 2. The positioning component 3 includes a contoured support block 302 and a mounting base 301 for installing the contoured support block 302. The plurality of contoured support blocks 302 are all different, and the plurality of contoured support blocks 302 are all in contact with the inner edge of the battery shell 2. The contoured support block 302 is detachably arranged on the side of the mounting base 301 by bolts. The mounting base 301 is detachably connected to the upper surface of the workbench 1 by a plurality of bolts. The mounting base 301 and the contoured support block 302 are both positioned and installed by two positioning pins 303. The lower surface of the mounting base 301 is provided with a plurality of first gaskets 304 for fine-tuning the height of the mounting base 301. A plurality of second gaskets 305 for fine-tuning the position of the contoured support block 302 are provided between the mounting base 301 and the contoured support block 302. The surfaces of the first gasket 304 and the second gasket 305 are respectively provided with grooves for avoiding bolts and positioning pins 303.

[0031] According to the above technical solution, it can be understood that the contoured support block 302 is installed on the side of the mounting base 301 by bolts and positioned by the locating pin 303. By inserting the second gasket 305, the position of the contoured support block 302 can be fine-tuned. The mounting base 301 is fixed to the surface of the workbench 1 by bolts and positioned by the locating pin 303. The height of the contoured support block 302 is adjusted by inserting the first gasket 304, which fits with the inner wall of the battery housing 2 to achieve the purpose of positioning and support, so that the special hole on the edge of the battery housing 2 corresponds to the surface of the top block 504.

[0032] Specifically, the upper surface of the workbench 1 is provided with a plurality of clamping assemblies 4 for clamping and fixing the edge of the battery shell 2. The clamping assembly 4 includes a first pressure rod 402 hinged on the surface of the first mounting frame 401 and a pad 403 fixedly connected to the upper surface of the workbench 1. The first pressure rod 402 is T-shaped, and the position of the first pressure rod 402 corresponds to the position of the top block 504. The first mounting frame 401 is detachably arranged on the upper surface of the workbench 1 by bolts. The middle part of the first pressure rod 402 is hinged with a first pull rod 404, and the lower end of the first pull rod 404 is hinged with a driving push rod for lifting the first pull rod 404, and the driving push rod is fixedly connected to the lower surface of the workbench 1.

[0033] According to the above technical solution, it can be understood that by driving the push rod to work, the first pull rod 404 is driven to descend, thereby pulling the first pressure rod 402 to rotate, so that the first pressure rod 402 is pressed downward, and with the cooperation of the pad 403, the battery housing 2 is clamped and fixed.

[0034] Specifically, the upper surface of the workbench 1 is provided with a plurality of press-fitting components 5 for pressing the ring into the special hole of the battery shell 2. The press-fitting component 5 includes a second pressure rod 502 hinged on the surface of the second mounting frame 501 and a top block 504 arranged on the upper surface of the workbench 1. The second mounting frame 501 is detachably arranged on the upper surface of the workbench 1 by bolts. The middle part of the second pressure rod 502 is hinged with a second pull rod 503, and the lower end of the second pull rod 503 is hinged with a driving push rod for lifting the second pull rod 503. The driving push rod is fixedly connected to the lower surface of the workbench 1. The second pressure rod 502 is hinged with a pressure head at one end away from the second mounting frame 501. The diameter of the lower end of the pressure head is larger than the diameter of the upper end. The position of the pressure head corresponds to the position of the top block 504. A sliding rod 5041 for guiding the ring is vertically slid inside the top block 504, and a spring 5042 is sleeved on the surface of the sliding rod 5041.

[0035] It can be understood that by driving the push rod to drive the second pull rod 503 to descend, the second pressure rod 502 is rotated on the surface of the second mounting bracket 501, thereby driving the pressure head to press downward. Since the diameters of the upper and lower ends of the pressure head are different, the axial direction of the pressure head is always kept vertical in the middle and lower part of the center of gravity. Therefore, when the pressure head presses the ring, the ring can enter the hole vertically. Under the action of the sliding rod 5041, it is convenient to guide and limit the ring. By setting the spring 5042, it is convenient to automatically reset the sliding rod 5041.

[0036] Specifically, a plurality of support columns 6 are symmetrically distributed on the upper surface of the workbench 1 , and the plurality of support columns 6 are detachably mounted on the surface of the workbench 1 by bolts.

[0037] It can be understood that by providing a plurality of support columns 6 , the middle portion of the battery housing 2 is supported to avoid deformation.

[0038] Specifically, a plurality of tool boxes 7 are placed on the edge of the workbench 1 .

[0039] It is understandable that the tool box 7 is provided to facilitate the storage of the rings and facilitate the workers to take them out.

[0040] In the present invention, the battery housing 2 is placed on the surface of the workbench 1 according to the multiple contoured support blocks 302, the battery housing 2 is positioned, and at the same time, the multiple sliding rods 5041 are inserted into the special holes, the driving push rod is operated, the first pull rod 404 drives the first pressure rod 402 to rotate on the surface of the first mounting frame 401, and the other end of the first pressure rod 402 is clamped and fixed to the edge of the battery housing 2 under the cooperation of the pad 403, and the staff sleeves the open ring on the upper end of the sliding rod 5041, and drives the second pull rod 503 to move downward by the driving push rod, so that the second pressure rod 502 rotates on the surface of the second mounting frame 501. The pressing head is moved to move downward. Due to the different diameters at the upper and lower ends of the pressing head, the central axis of the pressing head is always kept vertical under the action of the center of gravity. The pressing head presses the collar and the sliding rod 5041 to press the collar into the hole, and the sliding rod 5041 retracts into the inside of the top block 504. After the press-fitting is completed, the multiple driving push rods respectively drive the multiple first pull rods 404 and the second pull rods 503 to rise, so that the multiple second pressure rods 502 are separated from the surface of the battery shell 2, the limit of the battery shell 2 is released, and the press-fitted battery shell 2 is removed, and the sliding rod 5041 is automatically reset by the spring 5042, which is convenient for the press-fitting work to be carried out again.
