Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and in particular to an engine test bench. Background Technology

[0002] In today's manufacturing environment, engine performance testing is crucial for ensuring product quality and operational reliability. With the continuous evolution of engine design and technology, various new models, sizes, and batches of engines have emerged on the market. This necessitates testing equipment that can not only handle diverse engine types but also possess high efficiency, precision, and flexibility to meet rapidly changing demands.

[0003] Traditional engine testing platforms are mostly based on a fixed structural design, which limits their adaptability, especially when dealing with engines of different specifications, requiring significant time and manpower for reconfiguration. Furthermore, while some existing testing platforms offer basic adjustment functions, such as height or horizontal adjustment, they typically only support single-dimensional changes and cannot meet multi-dimensional adjustment needs. Therefore, the installation and connection of auxiliary systems such as oil pipes, water pipes, and other components become more difficult and error-prone, reducing work efficiency and potentially affecting the accuracy of test results due to improper installation. Utility Model Content

[0004] To overcome the aforementioned shortcomings, the technical problem to be solved is to provide an engine test bench.

[0005] The technical solution of this utility model is as follows: an engine test bench, including a base plate, casters, a lifting plate, a sliding table, a worktable, a push handle, and a power assembly. The test module is installed in the test chamber. Casters are installed at the four corners of the bottom of the base plate. The base plate is placed next to the test module. A push handle is connected to the left side of the base plate. The lifting plate is slidably connected to the top of the base plate in the vertical direction. The sliding table is slidably connected to the top of the lifting plate in the horizontal direction. The worktable is rotatably connected to the top of the sliding table in the horizontal direction. The power assembly is provided on the top of the lifting plate.

[0006] In one embodiment, the power assembly includes a second motor and a second screw. The second motor is mounted on the top left side of the lifting plate, and the second screw is connected to the output shaft of the second motor. The second screw is threadedly connected to the sliding table.

[0007] In one embodiment, the system further includes a first motor, a first screw, and a connecting cylinder. The first motor is installed in the middle of the base plate, and the connecting cylinder is connected to the middle of the bottom of the lifting plate. The first screw is connected to the output shaft of the first motor, and the first screw is threadedly connected to the connecting cylinder.

[0008] In one embodiment, the system further includes a slide cylinder, a slider, a fixed block, and a connecting block. The slide cylinders are symmetrically installed on the right side of the slide table, and each slide cylinder is slidably connected to a slider. Each slider is connected to a fixed block on its right side. The bottom right side of the worktable is symmetrically connected to a connecting block, and the upper end of the fixed block is rotatably connected to the corresponding connecting block.

[0009] In one embodiment, the system further includes a ladder groove block and a trapezoidal block. The trapezoidal block is connected to the right side of the base plate, and the ladder groove block is installed on the left side of the detection module. The trapezoidal block and the ladder groove block are engaged.

[0010] In one embodiment, the top of the workbench has several mounting holes arranged in a neat row to facilitate the installation of the engine to be tested.

[0011] The beneficial effects are as follows: 1. By setting up the first motor, the second motor and the slide cylinder, this utility model can accurately adjust the height, horizontal position and tilt angle of the engine respectively. This multi-dimensional adjustment capability enables the test bench to adapt to engines of different models and sizes, ensuring that all necessary oil and water pipelines can be connected smoothly. This not only improves the accuracy of the test, but also significantly improves work efficiency, reduces manual intervention, and provides great convenience for staff.

[0012] 2.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example: An engine test bench, such as Figure 1 and 3 As shown, the test bench includes a base plate 2, casters 3, a lifting plate 7, a sliding table 10, a worktable 15, a push handle 18, and a power assembly. The test module 1 is installed inside the test chamber. Other testing equipment is also installed next to the test module 1 to assist in completing engine testing. Casters 3 are installed at the four corners of the bottom of the base plate 2, allowing the entire test bench to move easily. The base plate 2 is placed next to the test module 1. The push handle 18 is connected to the left side of the base plate 2. The lifting plate 7 is slidably connected to the top of the base plate 2 in the vertical direction. The sliding table 10 is slidably connected to the top of the lifting plate 7 in the horizontal direction. The worktable 15 is rotatably connected to the top of the sliding table 10 in the horizontal direction. Several mounting holes are neatly arranged on the top of the worktable 15 to facilitate fixing the engine to be tested on the worktable 15 with bolts. The engine to be tested is transferred by the base plate 2 and the casters 3 to bring the engine closer to the test module 1. The power assembly is located on the top of the lifting plate 7.

[0020] like Figure 1 and 3 As shown, the power assembly includes a second motor 8 and a second screw 9. The second motor 8 is bolted to the top left side of the lifting plate 7. The output shaft of the second motor 8 is connected to the second screw 9. The second screw 9 is threadedly connected to the sliding table 10. Its forward or reverse rotation can drive the sliding table 10 to adjust its position relative to the engine under test in the left or right direction.

[0021] like Figure 2 As shown, it also includes a first motor 4, a first screw 5, and a connecting cylinder 6. The first motor 4 is installed in the middle of the base plate 2 by bolts. The connecting cylinder 6 is welded to the middle of the bottom of the lifting plate 7. The first screw 5 is connected to the output shaft of the first motor 4. The first screw 5 is connected to the internal thread of the connecting cylinder 6. The rotation of the first screw 5 can drive the connecting cylinder 6 to adjust the height in the vertical direction, so as to adjust the height of the lifting plate 7 and the engine to be tested.

[0022] like Figure 4 As shown, it also includes a slide cylinder 11, a slider 12, a fixed block 13, and a connecting block 14. The slide cylinder 11 is symmetrically mounted on the right side of the slide table 10 by bolts. The slider 12 is slidably connected to each slide cylinder 11. The fixed block 13 is welded to the right side of each slider 12. The connecting block 14 is symmetrically welded to the bottom right side of the worktable 15. The upper end of the fixed block 13 is rotatably connected to the corresponding connecting block 14. The fixed block 13 can move up or down, and can be pushed by the connecting block 14 to make the worktable 15 tilt in the left and right directions, that is, the posture conversion of left low and right high or left high and right low, so as to adjust the tilt angle of the engine to be tested.

[0023] like Figure 1 As shown, it also includes a ladder groove block 16 and a trapezoidal block 17. The trapezoidal block 17 is connected to the right side of the base plate 2, and the ladder groove block 16 is installed on the left side of the detection module 1. The trapezoidal block 17 and the ladder groove block 16 are engaged to ensure the accuracy of the test bench's parking position and provide a basic guarantee for the subsequent oil, water and electrical pipeline connections.

[0024] Before conducting engine testing, the engine to be tested is first securely fixed on the workbench 15. Then, the operator can use the push handle 18 to push the entire test bench smoothly into the testing chamber using the casters 3, and align the trapezoidal block 17 on the base plate 2 with the trapezoidal groove block 16 on the testing module 1 to ensure accurate positioning. Due to the different sizes and batches of each engine, in order to facilitate the connection of pipelines, the first motor 4, the second motor 8, and the slide cylinder 11 are started in sequence according to actual needs to finely adjust the height, horizontal position, and tilt angle of the engine until the optimal testing conditions are met.

[0025] Specifically, when height adjustment is required, the first motor 4 is activated, controlling its output shaft to rotate forward or backward, thereby rotating the first screw 5 and adjusting the height of the lifting plate 7. This simultaneously moves the sliding table 10, the worktable 15, and the engine under test on it up and down until the desired height is reached. After adjustment, the first motor 4 is turned off to ensure stability. When the engine position needs to be finely adjusted horizontally, the second motor 8 is activated, controlling its output shaft to rotate forward or backward, thereby rotating the second screw 9 and adjusting the position of the sliding table 10, bringing the engine closer to or further away from the detection module 1. This feature is particularly suitable for the rapid adaptation of engines of different sizes, improving testing efficiency. After adjustment, the second motor 8 is turned off to fix the position.

[0026] When the engine tilt angle needs adjustment, the slide cylinder 11 is activated, causing the slider 12 to move up or down, thereby changing the position of the fixed block 13. When the slider 12 moves upward, the fixed block 13 moves upward, pushing the right end of the worktable 15 upward through the connecting block 14, making the worktable 15 tilted with the left side lower than the right. Conversely, when the slider 12 moves downward, the fixed block 13 moves downward, pushing the right end of the worktable 15 downward through the connecting block 14, making the worktable 15 tilted with the left side higher than the right. This design allows for smooth pre-test preparation even for engines with special installation requirements, increasing the applicability of the equipment. After the tilt angle adjustment is completed, the slide cylinder 11 is closed to ensure stability. By adjusting the positions of the various components in the left, right, up, and down directions, as well as the tilt angle, different engines can be well adapted to the testing module 1, providing convenience for the staff. Finally, all necessary oil and water lines are correctly connected to the engine, and the formal performance testing process can begin.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
