Detailed Embodiments

[0021] The following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present invention, and are not intended to limit the present invention.

[0022] Reference Figures 1-3As shown, this solution provides a test tray for an engine, which includes a chassis 50, a first positioning component, a second positioning component, a third positioning component, and a fourth positioning component that can be set on the chassis 50. The first positioning component includes a positioning member and a fixing member that can move horizontally to adapt to different types of cylinder blocks. The second positioning component and the third positioning component each include a fixing member that can move horizontally to adapt to different types of cylinder blocks. The fourth positioning component includes a plurality of positioning tools adapted to different types of cylinder blocks. Each positioning tool can be set on the chassis 50 and includes a positioning member and a fixing member adapted to different types of cylinder blocks.

[0023] The chassis 50 is a support base, which is generally formed in a flat plate shape and is provided with a variety of other adapted components.

[0024] The first positioning component, the second positioning component, the third positioning component, and the fourth positioning component are respectively used to position the engine cylinder block so that the engine cylinder block can be fixedly supported on the test tray.

[0025] Among them, the first positioning component includes a positioning member and a fixing member. The positioning member can position the cylinder block relative to the chassis 50 to facilitate setting it at the target position. The fixing member is used to fix the cylinder block on the chassis 50. In order to adapt to different types of cylinder blocks, both the positioning member and the fixing member can move horizontally relative to the chassis 50 to position and fix the cylinder block according to the size of the cylinder block.

[0026] Among them, both the second positioning component and the third positioning component only include fixing members, and the fixing members can move horizontally to fix cylinder blocks of different sizes.

[0027] Among them, the fourth positioning component includes a plurality of positioning tools. According to different models of cylinder blocks, the corresponding positioning tool can be selected and installed on the chassis 50. Each positioning tool includes a positioning member and a fixing member that cooperate with the corresponding cylinder block to achieve the positioning and fixing of the cylinder block.

[0028] Among the four positioning components, there are at least two positioning members, so as to relatively position the cylinder block at two positions, and there are four fixing members, so as to fix the cylinder block at four positions.

[0029] In this solution, the four positioning components on the chassis can be adapted to different cylinder blocks through relative movement and selective corresponding installation, which simplifies the operation, shortens the operation time, and improves the test efficiency.

[0030] In some embodiments, the first positioning component, the second positioning component, the third positioning component, and the fourth positioning component are arranged on the chassis 50 in a quadrilateral form. The first positioning component and the second positioning component are spaced apart along a first horizontal direction. The first positioning component and the fourth positioning component are spaced apart along a second horizontal direction perpendicular to the first horizontal direction. The third positioning component is spaced apart from the second positioning component along the second horizontal direction and is spaced apart from the fourth positioning component along the first horizontal direction. Refer to Figures 1-3 As shown, the four positioning components are arranged at the four corner positions of the quadrilateral. When the mating cylinder block is generally quadrilateral in shape, the positioning and fixing of the cylinder block are achieved.

[0031] Further, in some embodiments, the first positioning component and the fourth positioning component correspond to the intake side of the cylinder block, and the second positioning component and the third positioning component correspond to the exhaust side of the cylinder block. The first positioning component and the fourth positioning component correspond to one side of the intake side of the cylinder block, and the second positioning component and the third positioning component correspond to one side of the exhaust side of the cylinder block. In other embodiments, each positioning component may also correspond to other edge positions of the cylinder block.

[0032] Among them, in some embodiments, the first positioning component includes a first positioning plate 11 adapted to a small-sized cylinder block, a first positioning pin and a first pressing strip 13 arranged on the first positioning plate 11, a second positioning plate 12 adapted to a medium-sized cylinder block and a large-sized cylinder block, a second positioning pin 14 and a first toggle clamp 15 arranged on the second positioning plate 12. The first positioning plate 11 can move along the first horizontal direction between a first position ( Figure 1 shown) corresponding to the small-sized cylinder block and a second position ( Figure 2 , Figure 3 shown). The second positioning plate 12 can move between a third position ( Figure 2 shown) corresponding to the medium-sized cylinder block and a fourth position ( Figure 3 shown) corresponding to the large-sized cylinder block. Among them, the small-sized cylinder block can be an 8L cylinder block, the medium-sized cylinder block can be a 12L cylinder block, and the large-sized cylinder block can be a 15L cylinder block. Of course, this solution is not limited thereto, and these are just some examples. The first positioning plate 11 is generally strip-shaped extending along the first horizontal direction, is provided with a strip-shaped hole thereon, and can be fixed to the chassis 50 by bolts passing through the strip-shaped hole; a first positioning pin is arranged on the upper surface of the first positioning plate 11, and the first pressing strip 13 can be fixed on the first positioning plate 11 by bolts, Figures 1-3Among them, the first pressing strip 13 blocks the first positioning pin. Specifically, a notch is formed at the bottom of one end (the upper end in the figure) of the first pressing strip 13, and the first positioning pin is located in the notch. The edge part of the cylinder block can accommodate the insertion of the first positioning pin and is pressed tightly by the upper end of the first pressing strip 13. A strip-shaped hole is formed on the first pressing strip 13 to allow it to adjust its relative position along the first horizontal direction with respect to the first positioning plate 11. A second positioning pin 14 is provided on the second positioning plate 12. The second positioning pin 14 is inserted into the bottom of the edge of the 12L cylinder block or the 15L cylinder block to achieve positioning. The first elbow clamp 15 can press tightly the edge of the 12L cylinder block or the 15L cylinder block to achieve fixation. Similarly, strip-shaped holes are also provided on the second positioning plate 12 and it is fixed to the chassis 50 by bolts. Among them, the cooperation between the bolts and the strip-shaped holes can limit the movement of the positioning plate along a specific direction.

[0033] Specifically, when it is necessary to set the 12L cylinder block or the 15L cylinder block, the first positioning plate 11 can be moved to the second position to avoid the larger-sized 12L cylinder block or 15L cylinder block.

[0034] Furthermore, in some embodiments, the second positioning plate 12 can move between a third position and a fourth position along a third horizontal direction that forms an angle with the first horizontal direction and the second horizontal direction. In the third position, the second positioning plate 12 is closer to the second positioning component. In the fourth position, the second positioning plate 12 is closer to the fourth positioning component. Refer to Figures 1-3 As shown, the strip-shaped hole on the second positioning plate 12 forms an angle with the first horizontal direction and the second horizontal direction and is in an inclined extension form. Correspondingly, the second positioning plate 12 also moves along the inclined third horizontal direction. As Figure 2 shown, the second positioning plate 12 is in the third position and is closer to the second positioning component to correspond to the 12L cylinder block with a smaller width; as Figure 3 shown, the second positioning plate 12 is relatively far from the second positioning component to correspond to the 15L cylinder block with a larger width.

[0035] In addition, in some embodiments, the second positioning component includes a third positioning plate 21 adapted to a small-sized cylinder block, a second pressing strip 23 provided on the third positioning plate 21, a fourth positioning plate 22 adapted to a medium-sized cylinder block and a large-sized cylinder block, and a third pressing strip 24 provided on the fourth positioning plate 22. The third positioning plate 21 can move along the first horizontal direction between a fifth position corresponding to the small-sized cylinder block ( Figure 1 shown) and a sixth position ( Figure 2 , Figure 3 shown). The fourth positioning plate 22 can move along the first horizontal direction between a seventh position corresponding to the medium-sized cylinder block ( Figure 2 shown) and an eighth position corresponding to the large-sized cylinder block (Figure 3 It moves between the positions shown. A strip-shaped hole along the first horizontal direction is provided on the third positioning plate 21, and it is fixed to the chassis 50 by bolts to allow adjustment of its relative position along the first horizontal direction. The second pressing strip 23 is fixed to the third positioning plate 21 by bolts and also has a strip-shaped hole, and its relative position with respect to the third positioning plate 21 can be adjusted. A notch is provided at the bottom of the lower end of the second pressing strip 23 to accommodate the edge of the cylinder block. The structures of the fourth positioning plate 22 and the third pressing strip 24 are similar to those of the third positioning plate 21 and the second pressing strip 23, and will not be repeated here. Among them, when fixing the medium-sized cylinder block or the large-sized cylinder block through the fourth positioning plate 22 and the third pressing strip 24, the third positioning plate 21 can move to the sixth position (as shown in Figure 2 and Figure 3 shown) to avoid the cylinder block.

[0036] Furthermore, in some embodiments, the fourth positioning plate 22 can move between the seventh position and the eighth position along a fourth horizontal direction that forms an angle with the first horizontal direction and the second horizontal direction. At the seventh position, the fourth positioning plate 22 is closer to the first positioning assembly, and at the eighth position, the fourth positioning plate 22 is closer to the third positioning assembly. A strip-shaped hole that forms an angle with the first horizontal direction and the second horizontal direction is provided on the fourth positioning plate 22 to limit the horizontal movement of the fourth positioning plate 22 along the inclined direction. At the seventh position, as shown in Figure 2 shown, the fourth positioning plate 22 is closer to the first positioning assembly to adapt to the width of the medium-sized cylinder block; at the eighth position, as shown in Figure 3 shown, the fourth positioning plate 22 is farther from the first positioning assembly to adapt to the width of the large-sized cylinder block.

[0037] In addition, in some embodiments, the second positioning plate 12 is located between the first positioning plate 11 and the fourth positioning assembly along the second horizontal direction, and the third positioning plate 21 is located between the fourth positioning plate 22 and the third positioning assembly (the fifth positioning plate 31) along the second horizontal direction. The second positioning plate 12 and the third positioning plate 21 are a set of structures that cooperate with each other, and the second positioning plate 12 and the fourth positioning plate 22 are another set of structures that cooperate with each other. In other embodiments, the first positioning plate 11, the second positioning plate 12, the third positioning plate 21, and the fourth positioning plate 22 can also be set to other relative position relationships, which will not be elaborated here, but those skilled in the art can easily think of them according to actual needs.

[0038] In addition, in some embodiments, the third positioning assembly includes a fifth positioning plate 31 adapted to the small-sized cylinder block, the medium-sized cylinder block, and the large-sized cylinder block, and a second elbow clamp 32 provided on the fifth positioning plate 31. The fifth positioning plate 31 can move along the first horizontal direction to the ninth position corresponding to the small-sized cylinder block (Figure 1 as shown), the tenth position corresponding to the medium-sized cylinder block ( Figure 2 as shown), and the eleventh position corresponding to the large-sized cylinder block ( Figure 3 as shown). The fifth positioning plate 31 can move between three positions to adapt to cylinder blocks of three different sizes. The second elbow clamp 32 on the fifth positioning plate 31 can press the cylinder block of the corresponding size, and a pressing plate for pressing the cylinder block is also provided on the fifth positioning plate 31.

[0039] In addition, in some embodiments, the fourth positioning assembly includes a sixth positioning plate 41 adapted to the small-sized cylinder block, a third positioning pin 42 and a third elbow clamp 43 provided on the sixth positioning plate 41, a seventh positioning plate 44 adapted to the medium-sized cylinder block, a fourth positioning pin 45 and a fourth elbow clamp 46 provided on the seventh positioning plate 44, an eighth positioning plate 47 adapted to the large-sized cylinder block, a fifth positioning pin 48 and a fifth elbow clamp 49 provided on the eighth positioning plate 47. When installing cylinder blocks of different sizes, positioning tools of different sizes need to be selected, that is, positioning plates of different sizes and the positioning pins and elbow clamps provided thereon. The sixth positioning plate 41, the seventh positioning plate 44 and the eighth positioning plate 47 are similar in structure but different in size, and corresponding positioning pins and elbow clamps are respectively provided thereon for positioning and pressing and fixing the cylinder block.

[0040] In addition, handle members are respectively provided on the first positioning plate 11, the second positioning plate 12, the third positioning plate 21, the fourth positioning plate 22 and the fifth positioning plate 31 to facilitate operation and push the corresponding positioning plate to move.

[0041] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, including any suitable combination of each specific technical feature. To avoid unnecessary repetition, the present invention does not separately describe various possible combination methods. But these simple modifications and combinations should also be regarded as the content disclosed by the present invention and all fall within the protection scope of the present invention.
