Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell cover processing equipment, and more specifically, to a welding fixture for electrolytic cell covers. Background Technology

[0002] As a key component in electrolytic cell production, the welding quality of the end plate and the curved aluminum plate directly determines the sealing performance, insulation performance, and overall structural stability of the electrolytic cell cover. During the welding process, tooling is required to precisely position and press the end plates and aluminum plates together to ensure a strong and accurate connection after welding.

[0003] However, existing limiting fixtures for welding the end plates of electrolytic cell covers to aluminum plates are mostly fixed-length integrated rigid structures, which have poor adaptability. They cannot be flexibly adjusted according to the different curvatures, lengths, and specifications of the aluminum plates and end plates. Furthermore, the end plate positioning structure lacks precise adjustment and synchronization mechanisms, which can easily lead to misalignment between the end plates and aluminum plate ends and welding angle deviations. At the same time, the fixture adjustment mechanism lacks precise scale markings and reliable locking functions. After adjustment, it is prone to loosening due to vibration and lacks the ability to sense clamping force, resulting in uneven stress on the aluminum plate, local deformation, or excessive gaps in the fit. In addition, different specifications of cell covers require the replacement of the entire fixture or complex modifications, which is cumbersome and inefficient, seriously affecting welding quality and production efficiency.

The support base 1 has a linear guide rail 2 along its length, and a slider 4 is fitted onto the linear guide rail 2. The slider 4 is driven by a motor 3 to slide along the linear guide rail 2. The slider 4 is equipped with an arc-adaptive clamping module, which includes multiple independent receiving components, each of which can be independently adjusted in height. End plate positioning and adjustment modules are installed on both sides of the slider 4.

[0022] The receiving assembly includes a roller 5, a mounting base 6, a height adjusting screw 7, and a slider 4. The roller 5 is made of polyurethane and is rotatably connected to the mounting base 6. The mounting base 6 is rotatably connected to the top of the height adjusting screw 7. The height adjusting screw 7 is vertically positioned, and its bottom end is slidably connected to the slider 4. An adjusting sleeve is threaded onto its exterior, and the bottom of the adjusting sleeve is rotatably connected to the slider 4. The surface of the height adjusting screw 7 is provided with a first scale marking pattern 13. The outside of the adjusting sleeve is provided with an indicator 14 corresponding to the first scale marking pattern 13. Several first locking grooves 15 are also evenly distributed around the outside of the adjusting sleeve. The number of first locking grooves 15 matches the scale marking pattern 13. A first locking element 16 is slidably connected to the surface of the slider 4, and its end is adapted to the first locking groove 15.

[0023] The end plate positioning and adjustment module includes mounting plates 8 slidably disposed on both sides of the slider 4. An abutment plate 9 is fixed to the top outer side of the mounting plate 8, and an elastic pad 10 is provided on the inner side of the abutment plate 9.
