Battery cover plate pole welding tool

Abstract

The invention discloses a battery cover plate pole column welding tool which comprises a supporting part used for supporting a battery cover plate. The pressing device is matched with the supporting part to press the pole; the pressing device comprises a main body part formed above the supporting part, a pressing driving mechanism used for driving the main body part to move up and down, a mounting hole formed in the main body part and corresponding to the position of the pole mounting groove, and a pole pressing part rotationally arranged in the mounting hole; the pole pressing and holding part is provided with a penetrating space which is vertically through and is used for enabling a welding head to penetrate downwards, and the pole pressing and holding part is provided with a shielding part for shielding the battery cover plate on a horizontal projection plane; and the rotating device is used for driving the pole pressing part to rotate so as to change the position of the shielding part. According to the battery cover plate pole welding tool, the problem of oblique pressing is solved through a simple structure, and the product yield is increased.

Description

technical field [0001] The present application relates to the technical field of tooling and fixtures, and in particular, to a welding tooling for a pole column of a battery cover plate. Background technique [0002] see figure 1 , the battery cover A includes a battery cover body A1, two pole mounting grooves A2 formed on the two battery cover bodies A1, two sealing rings A3 and two poles A4, the pole mounting grooves A2 A perforation A21 is formed therein. [0003] In the production process of the battery cover plate A, two sealing rings A3 are first installed in the position of the hole A21 of the pole installation groove A2, and then the corresponding pole A4 is installed in the pole installation groove A2. The two poles A4 are respectively pressed into the two pole installation grooves A2 through the battery cover plate pole pole welding tool, so that the edge of the pole A4 and the pole pole installation slot A2 are between the edges. Form seam welding (ie, form a c...

Problems solved by technology

The vertical output shaft and the "匚" structure lead to the need to set up a more complex support platform, base and connection structure, etc., and it is necessary to make more room for the design of the support platform, base and connection structure, so that the battery cover pole welding The structure of the tooling is more complicated and the production is more difficult

In addition, since the sealing ring A3 is made of soft material, and because the vertical output shaft, the "匚"-shaped connecting frame 110 and the pole A4 are not on the same axis, it is easy to cause The center of gravity is unstable, causing one side to tilt, making the pole A4 tilt relatively to the battery cover body A1, which affects the welding quality

In order to solve the baroclinic problem, it is necessary to design more complex and more precise structures to avoid the baroclinic problem as much as possible, but none of them can solve this problem well
