[0002] In the field of engine manufacturing, the engine housing, as a core load-bearing component, directly affects the overall engine performance and assembly precision through its structural design. With the development of market segmentation, engine housings are showing a trend towards diversified models, with significant differences in crankshaft cavity layout, positioning hole distribution, oil passage routing, and external dimensions between different models. Currently, mainstream assembly lines employ a modular assembly mode using a pallet-and-conveyor system. This involves pre-positioning the engine housing and crankshaft on a dedicated pallet, then sequentially transferring them to various workstations via a conveyor line to complete pressing, bolting, and other processes.

[0003] In the prior art, due to the complex structure and shape of the engine housing, a type of material tray can usually only be adapted to one type of engine housing, resulting in poor adaptability of the material tray. When changing to other types of engine housings, it is necessary to change the corresponding material tray, which is not only time-consuming, but also results in a variety of material trays, which is inconvenient for storage.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0020] In the field of engine manufacturing, the engine housing, as a core load-bearing component, directly affects the overall engine performance and assembly precision through its structural design. With the development of market segmentation, engine housings are showing a trend towards diversified models, with significant differences in crankshaft cavity layout, positioning hole distribution, oil passage routing, and external dimensions between different models. Currently, mainstream assembly lines employ a modular assembly mode using a pallet-and-conveyor system. This involves pre-positioning the engine housing and crankshaft on a dedicated pallet, then sequentially transferring them to various workstations via a conveyor line to complete pressing, bolting, and other processes.

[0021] In the prior art, due to the complex structure and shape of the engine housing, a type of material tray can usually only be adapted to one type of engine housing, resulting in poor adaptability of the material tray. When changing to other types of engine housings, the material tray needs to be changed, which is not only time-consuming, but also results in a variety of material trays, which is inconvenient for storage.

[0022] Based on this, an exemplary embodiment of this application provides an engine housing material tray. The tray includes a base plate and a housing support assembly and a crankshaft support assembly disposed on the base plate. The housing support assembly includes a support frame, a housing support plate assembly, and multiple sets of retractable positioning assemblies. Thus, when changing different housings, turning the positioning assemblies allows them to extend or retract from the housing support plate assembly to adapt to different housing models. This enables the material tray to adapt to multiple engine housing models. When changing from one engine housing model to another, only the positioning assemblies extending from the housing support plate assembly need to be adjusted to adapt to the new engine housing model, without needing to replace the entire tray, thus reducing the number of tray types.

[0023] Example 1: An exemplary embodiment of this application provides an engine compartment material tray, such as... Figure 1 and 2 As shown, the batching tray includes a base plate 10 and a housing support assembly 20 and a crankshaft support assembly 30 disposed on the base plate 10. The base plate 10 is provided with a lifting positioning hole 101. When the batching tray moves to a preset position on the conveyor line, a lifting mechanism disposed on the conveyor line can position and lift the batching tray through the lifting positioning hole 101. The housing support assembly 20 is used to support the engine housing. Multiple housing support assemblies 20 can be configured, and the structure of the housing support plate assembly 202 of each housing support assembly 20 can be different. Different grooves or recesses are provided on the top surface of the housing support plate assembly 202 to adapt to the structure of the housing. For example, as... Figure 1As shown, the batching tray includes four sets of housing support assemblies 20. Two housing support assemblies 20 on one side of the crankshaft support assembly 30 can support one engine housing, for example, the left engine housing; the two housing support assemblies 20 on the other side of the crankshaft support assembly 30 are used to support the right engine housing. The crankshaft support assembly 30 is used to support the crankshaft.

[0024] The housing support assembly 20 includes a support frame 201, a housing support plate assembly 202, and multiple sets of retractable positioning components 203. The support frame 201 is mounted on the base plate 10 and can be a support plate. The housing support plate assembly 202 is mounted on the support frame 201, and the multiple sets of retractable positioning components 203 are all mounted on the housing support plate assembly 202. Depending on the housing structure, the retractable positioning components 203 at different positions can be used to position the housing. When changing to a different housing, rotating the positioning components 203 allows them to extend or retract from the housing support plate assembly 202 to adapt to different housing models. This enables the material tray to adapt to various engine housing models. When changing from one engine housing model to another, only the positioning components extending from the housing support plate assembly need to be adjusted to adapt to the new engine housing model, eliminating the need to replace the entire tray and reducing the number of tray types.

[0025] like Figures 3 to 5As shown, the positioning component 203 includes a housing 2031, a positioning element 2032, an elastic element 2033, and a limiting element 2034. The housing 2031 is mounted on the box support plate assembly 202. The housing 2031 is hollow and has a bottom wall. A limiting groove 2035 is provided on the lower circumferential wall of the housing 2031. The limiting groove 2035 includes a first groove segment 2035a, a second groove segment 2035b, and a third groove segment 2035c connected in sequence. The second groove segment 2035b extends along the axial direction of the housing 2031. The first groove segment 2035a and the third groove segment 2035c are respectively connected to the two ends of the second groove segment 2035b, and both extend along the circumferential direction of the housing 2031. A positioning element 2032 is disposed within the housing 2031; the top end of the positioning element 2032 extends out of the housing 2031 and passes through the box-support plate assembly 202; one end of a limiting element 2034 is inserted into the positioning element 2032, preferably, the limiting element 2034 is radially inserted into the positioning element 2032, and the other end is disposed in a limiting groove 2035; an elastic element 2033 is sleeved on the positioning element 2032; a snap-fit ​​groove 2036 is formed at the top end of the positioning element 2032, preferably, the snap-fit ​​groove 2036 is a cross-shaped groove, but it can also be a straight groove or a star-shaped groove, etc., the shape of which only needs to be adapted to the shape of commonly used tools. By inserting a tool into the snap-fit ​​groove 2036 and twisting the positioning element 2032, the limiting element 2034 slides along the limiting groove 2035, thereby realizing the raising and lowering of the positioning element 2032 relative to the housing 2031. When the limiting member 2034 moves from the first groove segment 2035a through the second groove segment 2035b to the third groove segment 2035c, the positioning member 2032 moves towards the housing 2031, causing the end of the positioning member 2032 to retract to a position lower than or flush with the upper surface of the housing support plate assembly 202. When the limiting member 2034 moves from the third groove segment 2035c through the second groove segment 2035b to the first groove segment 2035a, the positioning member 2032 moves away from the housing 2031, causing the end of the positioning member 2032 to extend beyond the upper surface of the housing support plate assembly 202 and be higher than the upper surface of the housing support plate assembly 202. At this time, the end of the positioning member 2032 can cooperate with the positioning hole on the housing to achieve positioning of the housing.

[0026] The crankshaft support assembly 30 includes a support frame 201 disposed on the base plate 10 and a crankshaft bearing carrier plate 301 disposed on the support frame 201; preferably, as Figure 1 As shown, the crankshaft carrier plate 301 has multiple concentric crankshaft positioning holes 303 of different diameters, so that the crankshaft carrier plate 301 can be adapted to various crankshafts of different specifications.

[0027] In order to limit the position of the crank and facilitate the subsequent clamping of the crankshaft at the work station, the crankshaft support assembly 30 also includes a limiting block 302 disposed on the crankshaft carrier plate 301. The limiting block 302 forms a limiting groove with the opening facing upward, and the crank of the crankshaft can be placed in the limiting groove to limit the position of the crank.

[0028] In one exemplary embodiment, the ingredient tray further includes blocking components 40 disposed at both ends of the base plate 10. The blocking components 40 include mounting blocks 401 disposed on the base plate 10 and blocking blocks 402 disposed on the mounting blocks 401. The blocking blocks 402 are preferably made of polyurethane, which can mitigate impact between adjacent ingredient trays. A ingredient tray support frame 50 is also disposed on one side of the housing support component 20. The ingredient tray can be placed within the ingredient tray support frame 50, which holds the materials required during housing assembly, so that the materials can move together with the housing and crankshaft to the designated workstation. Support columns are also provided on the base plate 10 to accommodate different housing models.

[0029] Example 2: An exemplary embodiment of this application provides a pallet inspection fixture for an engine compartment filling pallet as described in Embodiment 1. The pallet inspection fixture includes a positioning plate 801 and positioning posts 802. The positioning plate 801 is provided with a plurality of first through holes 803 adapted to the position of the positioning component 203, second through holes 804 adapted to the position of the positioning hole 101, and a third through hole adapted to the position of the limiting block 302. When inspecting the filling pallet, the positioning component 203 is fully screwed to extend beyond the housing support plate component 202. The positioning post 802 is inserted into the positioning hole 101, and then the positioning plate 801 is placed on the filling pallet so that the positioning post 802 passes through the second through hole 804. The accuracy of the filling pallet is then checked to determine whether the positioning component 203 can smoothly pass through the first through hole 803. Using this pallet gauge to inspect the accuracy of batching pallets, it is only necessary to ensure the accuracy of the pallet gauge itself to determine whether the accuracy of the batching pallet to be inspected is qualified, without having to perform coordinate measuring machine inspection on all batching pallets to be inspected, thus saving inspection costs.
