Description

Technical Field

[0001] This utility model relates to the field of automobile final assembly production technology, specifically to an auxiliary tooling for unloading. Background Technology

[0002] Currently, in automobile assembly production, AGVs are used to transport the engine assembly and subframe assembly. Before transportation, the engine assembly and subframe assembly need to be placed on the engine assembly pallet of the AGV. Before placement, the engine assembly and subframe assembly are pre-assembled and suspended in mid-air. Two workers are needed to lift the subframe assembly for positioning, and another two workers are needed to lift the engine assembly for positioning. This is inefficient. For single-layer plate vehicles, it is relatively easy to align the holes. However, for double-layer plate vehicles, the lower plate has threaded holes, while the upper plate has no openings. When installing the engine, the positioning holes and positioning pins are located below the operator's effective field of vision. The positioning pins and positioning holes are obstructed and cannot be observed. It is necessary to observe and try repeatedly to install it in place. Frequent observation and attempts result in unnecessary and wasteful actions, which cannot meet the production rhythm, causing efficiency loss and potentially causing safety risks such as engine tipping.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, this embodiment provides an installation auxiliary tooling, including a first substrate 1, a second substrate 2, a first pin 3, a second pin 4, and a positioning pin 5.

[0023] like Figure 2 , Figure 3 As shown, the first base plate 1 includes a limiting plate 11 and a positioning plate 12. The limiting plate 11 has mounting holes 111, and positioning pins 5 are fixed within the mounting holes 111 for positioning the subframe assembly. In this embodiment, the positioning pins 5 are fixed within the mounting holes 111 by multiple first bolts. Specifically, threaded holes are formed around the top wall of the positioning pins 5, and four first bolts are provided, each passing through one of the four threaded holes in the limiting plate 11 to fix the positioning pins 5 within the mounting holes 111 of the limiting plate 11. First pins 3 are fixed at both ends of the limiting plate 11 near the positioning plate 12 for guiding and positioning the subframe assembly. For protection, in this embodiment, each first pin 3 is fixed to the limiting plate 11 by a second bolt. Specifically, each first pin 3 has a top internal thread structure. Two second bolts are provided, which pass through the limiting plate 11 at the two internal thread locations to fix the first pin 3 to the limiting plate 11 respectively. The limiting plate 11 is integrally connected to the positioning plate 12 along the Y-axis. The positioning plate 12 and the second base plate 2 are connected by a second pin 4. The positioning pin 5 and the first pin 3 are all set perpendicular to the extended surface of the second base plate 2. The first base plate 1, the second base plate 2, the first pin 3, the second pin 4, and the positioning pin 5 are all made of 45 steel.

[0024] like Figure 2 , Figure 3 As shown, a first positioning hole 121 is provided through the positioning plate 12, and a second positioning hole 21 is provided through the second base plate 2 at the position corresponding to the first positioning hole 121. The second positioning hole 21 is used to connect with the positioning pin on the engine assembly tray to securely support the subframe assembly. In this embodiment, the first positioning hole 121 is circular and the second positioning hole 21 is U-shaped.

[0025] like Figure 2 , Figure 3 As shown, in this embodiment, the top of each second pin 4 is fixed to the positioning plate 12 by a third bolt, and the bottom of each second pin 4 is fixed to the second base plate 2 by a fourth bolt. Specifically, the second pin 4 has an internal thread structure at both the top and bottom. Four third bolts are provided, which pass through the positioning plate 12 at the four internal thread locations to fix the top wall of the second pin 4 to the positioning plate 12 respectively. Four fourth bolts are provided, which pass through the second base plate 2 at the four internal thread locations to fix the bottom wall of the second pin 4 to the second base plate 2 respectively.

[0026] In use, the engine assembly pallet is fixed on the AGV trolley, and the engine assembly and subframe assembly are vertically suspended above the engine assembly pallet. The worker inserts the positioning pin 5 into the positioning hole of the subframe assembly, and the AGV trolley drives the engine assembly pallet to rise. The positioning pin on the engine assembly pallet passes through the second positioning hole 21 and the first positioning hole 121 in sequence to support and position the subframe assembly. Then, the position of the engine assembly is finely adjusted to efficiently place the engine assembly and subframe assembly onto the engine assembly pallet. Then, the unloading auxiliary tooling is removed, and finally, the AGV trolley drives the engine assembly and subframe assembly into the next process.
