[0033] As an embodiment further provided by the present invention, the first clamping block 31 and the second clamping block 32 are both provided with grooves matched with the housing member 4 , and the grooves are square grooves 30 , circular grooves 33 or elliptical grooves 34 .

[0034] Specifically, a plurality of circular holes are provided on the bottom plate 1 to facilitate the installation of various parts. A first clamping block 31 is symmetrically provided on the bottom plate 1. The cylinder 2 is symmetrically provided on the bottom plate 1, and a push plate 21 is provided on the output end of the cylinder 2. An adapter plate 3 is provided on one side of the push plate 21. The adapter plate 3 is fixed to the push plate 21 by bolts. A second clamping block 32 matching the first clamping block 31 is provided on the adapter plate 3. The cushion block 6 is symmetrically provided on the bottom plate 1. The shell member 4 is provided on the cushion block 6. Both ends of the shell member 4 are clamped with lining members 5. The first clamping block 31 and the The second clamp block 32 is driven by the cylinder 2 to clamp the shell part 4. The first clamp block 31 and the second clamp block 32 are both provided with a groove, and the groove size and shape are consistent. When the shell part 4 is placed on the cushion block 6, the cylinder 2 is output to push the first clamp block 31 on the connecting plate close to the second clamp block 32. During the sliding process, the first clamp block 31 contacts the shell part 4 and applies pressure to it. At the same time, with the support of the lining part 5, the shell part 4 that has been offset is corrected so that the overall shape is within the qualified range, which facilitates the subsequent welding process of the battery top cover and improves the quality of welding.

[0035] As an embodiment further provided by the present invention, the first clamp block 31 and the second clamp block 32 are both provided with grooves matching with the shell member 4, and the grooves are square grooves 30, circular grooves 33 or elliptical grooves 34. The clamp blocks can be replaced to the corresponding first clamp block 31 and second clamp block 32 according to the shape of the shell, so as to better shape the shell member 4.

[0036] As an embodiment further provided by the present invention, the shell member 4 is a square shell 41, a round shell 42 and an elliptical shell 43, and the three shells correspond to the square groove 30, the round groove 33 and the elliptical groove 34 respectively. The shells of the batteries are mostly square, round or elliptical, and the tooling is suitable for shaping these three types.

[0037] As an embodiment further provided by the present invention, the lining member 5 is a square lining 51, a circular lining 52 or an elliptical lining 53, and the square lining 51, the circular lining 52 or the elliptical lining 53 respectively correspond to the square shell 41, the circular shell 42 or the elliptical shell 43, and the lining member 5 is mainly arranged at both ends of the shell member 4 to support the two ends of the shell member 4, so that the first clamping block 31 can better shape the shell member 4 when it is in contact with the second clamping block 32.

[0038] As an embodiment further provided by the present invention, when the lining member 5 is a square lining 51, the square lining 51 has a square block 513, a first handle 511 is provided on one side of the square block 513, and an inclined portion 514 is provided on the other side thereof. A first cover plate 512 is also provided on the square block 513, and the first cover plate 512 plays the effect of supporting the square block 513. A hand-held wrench is used to put the square lining 51 into the two ends of the square shell 41. Since one side of the square block 513 is the inclined portion 514, the assembly efficiency of the square block 513 and the square shell 41 is improved. Similarly, the circular lining 52 is a second handle 520. By holding the second handle 520, the circular block 522 on the second cover plate 521 is inserted into the two ends of the circular shell 42. The elliptical lining 53 has an elliptical block 532, and a third cover plate 531 and a third handle 530 are provided on one side of the elliptical block 532. The elliptical block 532 is inserted into the elliptical shell 53 by the third handle 530.

The two kinds of grooves provided on the cushion block 6 are arc grooves 61 and conical grooves 62, respectively. The cushion block 6 is divided into two kinds, and a suitable cushion block 6 is selected according to the difference in the shaping of the shell member 4, so as to improve the supporting effect on the shell member 4 and make its shaping more stable. The conical angle of the conical groove 62 is between 40° and 75°, and the elliptical shell 43 is more suitable for the cushion block 6 with the conical groove 62.

[0040] Working principle: First, according to different shell parts 4, select the corresponding first clamp block 31, second clamp block 32 and lining part 5. If an elliptical shell 43 is selected, it is necessary to select a pad block 6 with a conical groove 62. After the selection is completed and installed on the base plate 1, the lining part 5 is installed on both ends of the shell part 4, and then placed on the pad block 6. The cylinder 2 is used to output to push the first clamp block 31 on the adapter plate 3 to fit the second clamp block 32. During the fitting process, the shell part 4 is squeezed. With the support of the lining part 5, the shape of the shell part 4 is fine-tuned to a qualified shape, thereby completing the shaping of the shell part 4, thereby facilitating the subsequent welding of the battery cover and improving the welding effect.
