Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts assembly, in particular to a tool for assembling an air supply unit. Background Art
[0002] At present, the air pump and bracket assembly of the automobile chassis air suspension system are locked and connected by a shock-absorbing assembly. The existing assembly method is: first, the air pump is placed directly on the workbench, and then the bracket assembly is locked and connected to it using the shock-absorbing assembly. The disadvantages of this assembly scheme are: (1) When installing the shock-absorbing assembly, since the air pump and the bracket assembly are both special-shaped parts, there is no flat surface, resulting in unstable placement. During the assembly process, it is difficult to match the screws with the threaded holes, which affects the installation efficiency; (2) During the assembly process, due to the unstable placement of the parts, the threaded holes and the screws cannot be well matched. There is a great risk of screw stripping during assembly, resulting in part scrapping and increased manufacturing costs; (3) Since the various parts cannot be fixed, the parts will rotate during the tightening process of the shock-absorbing screws, making it extremely difficult for operators to operate.

[0023] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.
[0024] like Figure 1-2 As shown, the present embodiment proposes an air supply unit assembly tool, including an operating base plate 1, on which an air pump support assembly and a sheet metal bracket support assembly are provided. The air pump support assembly is used to position and support the air pump, and its contour is adapted to the shape of the air pump. The sheet metal bracket support assembly is used to position and support the sheet metal bracket, and its contour is adapted to the shape of the sheet metal bracket.
[0025] Specifically, the operating base plate 1 in this embodiment is made of AL6061 film-coated aluminum plate (the main alloying elements in the 6061 alloy are magnesium and silicon, which has medium strength, good corrosion resistance, weldability, and good oxidation effect), and is milled by CNC (the abbreviation of Computerized Numerical Control, also known as CNC machine tools or CNC lathes). The flatness of the operating base plate 1 is controlled within 0.02 mm.
[0026] In this way, the air pump and the sheet metal bracket can be positioned and fixed on the operating base plate 1 through the air pump support assembly and the sheet metal bracket support assembly to maintain the relative position relationship between the two. Then the shock-absorbing screws can be quickly paired with the threaded holes, thereby improving the assembly efficiency. It can effectively avoid the problem of slipping threads during the assembly process due to misalignment of the screws and the threaded holes, and effectively reduce the scrap rate and manufacturing cost of the product.
[0027] Further, if Figure 1 As shown, the sheet metal support assembly includes:
[0028] The bracket front positioning block 2 is installed on the front side of the upper end of the operating base plate 1; specifically, it can be made of AL6061 material and processed by CNC. During installation, it is positioned with the operating base plate 1 through the φ6mm positioning pin 15 and then fixed with the M6 screw 14.
[0029] The bracket support block 3 is installed on the upper left side of the operation base plate 1. During installation, it is positioned using the φ6mm positioning pin 15 and then fastened to the operation base plate 1 using the M10 screw 13.
[0030] The bracket side positioning block 4 is installed on the upper right side of the operation base plate 1. During installation, it is positioned using the φ6mm positioning pin 15 and then fastened to the operation base plate 1 using the M10 screw 13.
[0031] Furthermore, an L-shaped through-slot 10 is defined within the upper inner portion of the bracket's front positioning block 2. A nylon spacer 11 is secured within this slot, its upper surface flush with the upper surface of the bracket's front positioning block 2. Nylon spacer 11 is made of PA66 (polyhexamethylene adipamide, commonly known as nylon-66), a material with excellent mechanical properties that can withstand high loads and shocks while maintaining good stability. CNC milling prevents paint peeling from parts and tooling during assembly.
[0032] The nylon pad 11 can be fastened to the L-shaped through slot 10 by means of countersunk screws 12 (M6). Specifically, for secure fixation, the nylon pad 11 can be fastened by means of three countersunk screws 12 .
[0033] In this embodiment, the air pump support assembly includes:
[0034] The air pump front positioning block 6 is installed on the rear side of the upper end of the operating base plate 1;
[0035] The air pump side positioning block 5 is installed on the side of the air pump front positioning block 6 close to the bracket support block 3;
[0036] The air pump auxiliary support block 7 is installed between the bracket support block 3 and the air pump front positioning block 6
[0037] The air pump cylindrical support block 8 is installed between the air pump side positioning block 5 and the bracket front positioning block 2;
[0038] The front positioning block 6 of the air pump, the side positioning block 5 of the air pump and the auxiliary support block 7 of the air pump are all set to an L-shaped structure, and an arc-shaped transition is provided between the bottom plate and the side plate of the L-shaped structure. The upper end surface of the side plate is flush with the upper end surface of the sheet metal support assembly. The bottom plate of the L-shaped structure is fixed on the operating bottom plate 1 and is used to support the air pump.
[0039] It should be noted that the air pump front positioning block 6, the air pump side positioning block 5, the air pump auxiliary support block 7 and the air pump cylindrical support block 8 are all positioned by φ6mm positioning pins 15 and then fastened and installed on the operating base plate 1 using M6 screws 14.
[0040] Specifically, the material of the air pump support assembly (air pump front positioning block 6, air pump side positioning block 5, air pump auxiliary support block 7 and air pump cylindrical support block 8) is set to nylon and is processed by CNC milling. Nylon has good impact resistance and can effectively resist the impact on the tooling when placing the air pump. It is not easy to wear and tear, and can also prevent the air pump from being bumped and damaged.
[0041] In summary, the air pump and the sheet metal bracket are first positioned and fixed on the operating base plate 1 through the air pump support assembly and the sheet metal bracket support assembly to maintain the relative positional relationship between the two. Then, when the shock-absorbing screws are matched and locked with the threaded holes, the air pump and the sheet metal bracket will not rotate, which is convenient for the operator to assemble.
[0042] At the same time, the four corners of the bottom end of the operating base plate 1 in this embodiment are all equipped with pads 9. The pads 9 are made of SUS304 stainless steel and are made by turning technology.
