[0002] The top cover of the new energy battery includes a top cover body and a pole assembly arranged on the top cover body. Usually, the pole assembly is divided into two groups for positive and negative connection. The pole assembly usually includes a pole, a cover plate and a sealing ring. The pole is sequentially penetrated with a sealing ring, a top cover body and a cover plate from bottom to top, and the pole is riveted with the top cover body and the cover plate by stamping the pole from top to bottom, and the sealing ring is squeezed to achieve upper and lower sealing.

[0003] Among them, in order to adapt to the processing of the above-mentioned new energy battery top cover, corresponding riveting tooling is required. The existing riveting tooling usually has a positioning cavity adapted to the outer peripheral shape of the top cover body, so that the top cover body, pole, cover plate, and sealing ring are initially assembled and placed in the positioning cavity, and then riveting is achieved by stamping the pole downward.

[0004] However, actual production found that the positioning accuracy of the pole was poor. For example, the gap error between the top cover body and the positioning cavity, and the gap error between the pole and the top cover body caused the actual position of the pole punched by the stamping device to deviate from the preset position. Therefore, the stamping did not meet the requirements, resulting in the produced battery top cover being defective and unusable. Utility Model Content

Specifically, the pole assembly includes a pole 92, a cover plate 93 and a sealing ring 94, and the cover plate 93 is provided with a first mounting hole 911 passing through the first mounting hole 911. The second mounting hole 931 that runs through the upper and lower parts is set, and the pole 92 has a three-stage stepped structure.

In addition, the sealing ring 94 is set between the lowest step section and the top cover body 91, so that when the pole 92 is riveted, the sealing ring 94 is squeezed to achieve the upper and lower sealing of the top cover body 91.

[0033] like Figure 1-Figure 7 As shown, the riveting tooling includes a tooling base 1 and a tooling upper cover 2; wherein, a first positioning cavity 11 is provided on the tooling base 1, and the inner circumferential wall shape of the first positioning cavity 11 is adapted to the outer circumferential shape of the top cover body 91, and a fixed support seat 3, a floating support seat 4 and a reset member 5 are respectively provided in the first positioning cavity 11 corresponding to each group of pole assemblies, the fixed support seat 3 is fixedly installed on the tooling base 1 by means of bolts, the floating support seat 4 is sleeved on the outer circumference of the fixed support seat 3, and the floating support seat 4 can slide up and down relative to the fixed support seat 3, the inner circumferential wall of the floating support seat 4 and the upper surface of the fixed support seat 3 enclose a second positioning cavity 6, and the reset member 5 is used to reset the floating support seat 4 upward.

[0035] In conjunction with the above-mentioned tooling, during the riveting process, when the stamping device stamps the pole 92 downward, the tooling upper cover 2 is simultaneously pushed downward, so that during the stamping deformation of the pole 92, although the floating support seat 4 is pushed downward to reduce the depth of the second positioning cavity 6, the second positioning cavity 6 can still position the pole 92 to prevent the pole 92 from shifting during the stamping process and causing stamping to form defective products, and after the stamping is completed, the top cover body 91 is pushed downward to the specified position.

The two travel limit parts 42 are arranged on the front and rear sides of the outer peripheral wall of the floating support seat 4 and protrude outward. The two groups of travel limit grooves 12 are arranged on the front and rear sides of the inner peripheral wall of the mounting cavity 13 and are recessed inward, so that the stability of the limit is improved through the cooperation of the two groups of travel limit parts 42 and the travel limit grooves 12.

[0039] Preferably, the fixed support seat 3 is arranged in the installation cavity 13, and the guided sliding of the floating support seat 4 is realized under the restriction of the outer peripheral wall of the fixed support seat 3, so as to further improve the sliding stability of the floating support seat 4 by placing the fixed support seat 3 inside and the inner peripheral wall of the installation cavity 13 outside.

[0040] The floating support seat 4 has a relative position to the fixed support seat 3.

Specifically, the first extension portion 151 extends into the first positioning cavity 11, so that the outer periphery of the top cover body 91 needs to be limited within each first extension portion 151, and the gap between the top cover body 91 and the first extension portion 151 is smaller than the gap between the top cover body 91 and the peripheral wall of the first positioning cavity 11, thereby improving the accuracy of peripheral positioning. In addition, the second extension portion 152 extends upward to make the height of the first extension portion 151 higher, which can ensure that the top cover body 91 is positioned by the first extension portion 151 in the first state, ensuring full positioning to improve assembly accuracy, and the alignment cavity 22 allows the second extension portion 152 to extend into the alignment cavity 22 in the second state to prevent interference between the tooling base 1 and the tooling upper cover 2.
