Description

Technical Field

[0001] This utility model relates to the field of battery box production and processing technology for new energy vehicles, and in particular to a beam welding fixture. Background Technology

[0002] With the development of new energy vehicles, the requirements for the contour of the internal mounting beams of new energy vehicle battery boxes are constantly increasing, and the requirements for welding fixtures are also increasing accordingly. Welding fixtures generally include fixture fixing mechanisms that clamp the beams vertically and horizontally. Among them, the side-push clamping mechanism is used to push and clamp the beams on the water surface. The side-push clamping can eliminate clamping and material errors, ensure that the weld height and penetration depth of the box are consistent, improve welding quality, and avoid batch quality problems.

[0003] However, in practical applications, the beam may have already deformed or had significant errors during the preceding production process. The side-push clamping mechanism generally includes a fixed positioning component and a side-push mechanism. The beam is first placed between the fixed positioning component and the side-push mechanism, and then clamped. When the beam deforms, the contact area between the fixed positioning component and the beam is small. When the side-push mechanism pushes the beam, the contact position between the fixed positioning component and the beam will generate greater pressure, making the beam more prone to scratches.

[0021] The following is for reference. Figures 1 to 7 Describes the beam welding fixture according to an embodiment of the present utility model.

[0022] like Figures 1 to 3 As shown, the beam welding fixture according to an embodiment of the present utility model includes: a workbench 100 and at least one set of positioning components. The positioning components include a movable positioning mechanism 300 and a pushing positioning mechanism 200 disposed on the workbench 100. A space is formed between the movable positioning mechanism 300 and the pushing positioning mechanism 200 that allows the beam 900 to be placed from top to bottom. The pushing positioning mechanism 200 can push the beam 900 to abut against the movable positioning mechanism 300 to fix the beam 900 to the workbench 100. The movable positioning mechanism 300 includes a movable seat 310 and an abutment block 320 disposed on the movable seat 310. The abutment block 320 is used to abut against the beam 900. The movable seat 310 is rotatably disposed on the worktable 100 through a rotating shaft mechanism extending in the vertical direction. The movable seat 310 allows the abutment block 320 to better adapt to the deformed beam. When the beam 900 is pushed, the abutment block 320 can have a good tight fit with the beam 900, making it less likely to find pressure concentration and reducing the occurrence of scratches on the beam 900.

[0023] like Figures 5 to 7As shown, in some embodiments of this utility model, the push positioning mechanism 200 includes a mounting base 210, a drive unit 220, a drive block 230, and a slider 240. The mounting base 210 is mounted on the worktable 100. The drive unit 220 is disposed on the mounting base 210 and can drive the drive block 230 to move in the up and down direction. The slider 240 is slidably disposed on the mounting base 210. The drive block 230 is provided with a first inclined surface 231, and the slider 240 is provided with a second inclined surface 241 that can abut against the first inclined surface 231. When moving up or down, the slider 240 is driven to move closer to the movable positioning mechanism 300 through the abutment cooperation of the first inclined surface 231 and the second inclined surface 241. The slider 240 is provided with a pushing block 250 for pushing the beam 900. That is, the up-and-down driving unit 220 is used in conjunction with the inclined surface structure to push the beam 900. Compared with the traditional direct push structure (such as cylinder direct push), it reduces the arrangement of mechanisms on the horizontal plane (working plane 100) and facilitates the layout of other mechanisms (such as other positioning mechanisms and detection mechanisms of the beam).

[0024] like Figure 2 , Figure 5 , Figure 6 As shown, in some embodiments of this utility model, the drive unit 220 is a cylinder, which is vertically mounted on the mounting base 210 (the axial direction is up and down), and the cylinder is partially or entirely located below the worktable 100, so as to reduce the space occupied above the worktable 100 and facilitate the layout of other mechanisms.

The first slide rail mechanism extends along the direction of relative sliding between the first inclined surface 231 and the second inclined surface 241. The first slide rail mechanism cooperates with the inclined surface pushing structure, so that when the drive block 230 moves up and down, the slider 240 can be moved by the drive block 230, thereby achieving clamping and loosening of the beam 900.

[0028] Specifically, in the embodiment, the first inclined surface 231 and the second inclined surface 241 are a pressing fit structure. That is, when the driving block 230 moves down, it can push the second inclined surface 241 through the first inclined surface 231, so that the slider 240 moves towards the movable positioning mechanism 300 to press the beam 900. When the driving block 230 moves up, it can drive the slider 240 to move away from the movable positioning mechanism 300 through the first slide rail mechanism to release the beam 900.

[0038] like Figure 3 , Figure 4 As shown, in some embodiments of this utility model, each movable seat 310 is equipped with two guide pins 311, and the two guide pins 311 are opposite to each other. Correspondingly, the worktable 100 is equipped with two corresponding arc grooves 101 to cooperate with the guide pins 311, so as to improve the stability of the rotation of the movable seat 310.

[0039] like Figure 3 , Figure 4 As shown, in some embodiments of this utility model, the rotating shaft mechanism includes a shaft pin 330. The upper part of the shaft pin 330 is a smooth shaft structure, which can be rotatably engaged with the rotating hole 310a on the movable seat 310. The lower part of the shaft pin 330 is an external thread structure, which engages with the first threaded hole 100a on the worktable 100 to fix the shaft pin 330 to the worktable 100, thereby allowing the movable seat 310 to be rotatably mounted on the worktable 100.
