Description

Technical Field

[0001] This patent application relates to an auxiliary processing device for welding support brackets, and more particularly to an auxiliary processing device for welding power battery bracket assemblies for commercial electric vehicles. Background Technology

[0002] The power batteries of commercial electric vehicles require automakers to install power battery pack brackets within the battery compartment of the vehicle body. These brackets typically consist of symmetrical left and right unit brackets assembled and welded together. This manufacturing process requires an auxiliary welding station. The welding station's base plate has two sets of corresponding locating pins arranged according to the positions and number of power battery mounting holes. The left and right unit brackets are positioned by these locating pins before being welded together. Even when using power battery packs of the same manufacturer and specifications, the existing welding stations are unsuitable for welding support brackets of different specifications due to the variety of electric vehicle types and specifications. The main technical problems include: the locating pins cannot be disassembled and adjusted; the fixed outer diameter of the locating pins cannot accommodate battery pack brackets with other hole diameters; and the inability to flexibly adjust the spacing between the left and right unit brackets according to different process design specifications. Overall, the lack of flexible adjustment capability results in poor processing adaptability. Summary of the Invention

[0003] The purpose of this patent application is to provide a universal welding station for commercial electric vehicle power battery pack brackets, which allows for flexible adjustment of the design structure according to different welding processes and solves the technical problem of poor adaptability in assembly and processing.

[0017] The following detailed embodiments will illustrate the universal welding station for the power battery pack bracket of this commercial electric vehicle and its application technology, and explain its application technology effects.

[0018] This commercial electric vehicle power battery pack bracket universal welding station consists of a welding station fixed to a base.

[0019] Since the core structure of this patent lies in the welding station and the assembly structure between the welding station and the power battery pack bracket, the base is merely a fixed support platform for the welding station. Therefore, even if the accompanying drawings do not show the base, it will not affect the unambiguous understanding of the technical solution of this patent by those skilled in the art.

[0020] The aforementioned soldering station, such as Figure 1 As shown, it includes left and right bracket base plates 1 and the spacing adjustment slide of the bracket base plates 1.

[0021] The aforementioned spacing adjustment slide consists of two parallel sliding strips 2 with symmetrically arranged groove holes 9, forming a guide slide for sliding and assembling the left and right bracket base plates 1 to adjust the spacing between them. The groove holes 9 are elongated holes facing the direction of the slide, and their lengths are set according to the spacing H adjustment range required by the process of the left and right bracket base plates 1. In this embodiment, the spacing adjustment range of the left and right bracket base plates 1 is set between 575 and 985 mm.

[0022] like Figure 2 As shown, each hole at the four corners of each bracket base plate 1 and the corresponding sliding groove hole 9 on the slide bar 2 are provided with bolt sliding pins 3. When the left and right bracket base plates 1 are adjusted to the required spacing H, the left and right bracket base plates 1 are fixed by the cooperation of nuts and bolt sliding pins 3.

[0023] The left and right bracket base plates 1 serve as positioning plates for the left and right power battery pack assembly unit brackets 41 and 42, respectively. They are provided with positioning parts 5 corresponding to the power battery pack mounting holes and the positioning holes of the power battery pack assembly unit brackets 41 and 42. When the left and right bracket base plates 1 are locked at a set distance, the process welding position of the main frame 10 between the left and right assembly unit brackets 41 and 42 is also locked.

[0024] To accommodate the positioning and welding of power battery pack brackets of different specifications, the aforementioned bracket base plate slide spacing adjustment structure was adopted, and the positioning part 5 was improved.

[0025] The positioning part 5 consists of bolts 31 and bolt sleeves 30 assembled by corresponding threaded engagement between the bracket base plate 1 and the power battery pack mounting holes. After assembly, all bolt sleeves 30 are located on the same positioning surface of the positioning unit brackets 41 and 42, serving as welding positioning pins for the left and right unit brackets 41 and 42. Figure 1 As shown, each bracket base plate 1 has six positioning parts 5 arranged in two rows and three columns.

[0026] All bolts 31 are of uniform specifications, thus compatible with any adjusted processing specifications; the bolt sleeve 30 has the same inner diameter as the bolt 31, and its outer diameter can be selected according to the positioning hole diameter of different specification unit brackets 41 and 42. For example, the positioning hole diameter of unit brackets 41 and 42 is... When the outer diameter is [value missing], then select the installation outer diameter [value missing]. Bolt sleeves; if the positioning hole diameters of unit brackets 41 and 42 are When the outer diameter is [value missing], then select the installation outer diameter [value missing]. The bolt sleeves greatly expand the applicability of this commercial electric vehicle power battery pack bracket welding station to welding brackets of different specifications, making it a universal welding station. Furthermore, bolt sleeves with an outer diameter slightly smaller than the power battery pack mounting holes (30mm) can be selected to facilitate fine-tuning of the actual positioning and installation process of the bracket.
