[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0029] A gearbox test bench includes a first operating platform 1 and a second operating platform 2. The first operating platform 1 is fixedly connected to the second operating platform 2. A moving platform 10 is provided above the first operating platform 1, and a gearbox body 4 is provided above the moving platform 10. A lifting platform 7 is provided above the second operating platform 2, and a detection motor 5 is provided above the lifting platform 7. The output end of the detection motor 5 is movably connected to the connection end of the gearbox body 4, and a connecting sleeve 6 is provided between the two. It further includes:

[0030] A height adjustment component, which is located at the top of the second operating platform 2 and is used to adjust the height of the lifting platform 7 and thus adjust the height of the detection motor 5 to adapt to gearbox bodies 4 of different heights;

[0031] A longitudinal adjustment component, which is located on the outer surface of the lifting platform 7 and is used to drive the detection motor 5 for longitudinal adjustment, so as to be applicable to gearbox bodies 4 of different widths;

[0032] A transverse adjustment component, which is located at the top of the first operating platform 1 and is used to adjust the distance between the moving platform 10 and the detection motor 5 and thus adjust the distance between the gearbox body 4 and the detection motor 5, so that the connection end of the gearbox body 4 can be close to the output end of the detection motor 5;

[0033] A clamping component, which is located on the outer surface of the moving platform 10 and is used to fix gearbox bodies 4 of different sizes on the moving platform 10. The gearbox body 4 and the detection motor 5 are connected through the connecting sleeve 6. By starting the detection motor 5, various performance tests of the gearbox can be carried out.

[0034] Further, the height adjustment assembly includes a connecting rod 8, a first guide rail 9, a first slider 13, and a forward plate 23. Two symmetrically distributed first guide rails 9 are fixedly connected to the top of the second operation table 2. The outer surfaces of the two first guide rails 9 are both slidably connected with first sliders 13. The top of the two first sliders 13 is fixedly connected with a forward plate 23. The outer surfaces on both sides of the forward plate 23 are rotatably connected with connecting rods 8. The two connecting rods 8 are arranged in an X shape. The bottom outer surfaces of the two connecting rods 8 are rotatably connected to the top of the second operation table 2. The tops of the two connecting rods 8 are both rotatably connected to the bottom of the lifting table 7. Since the fourth threaded rod 24 is sleeved with the forward plate 23, the forward plate 23 will move along the first guide rail 9, and at the same time drive the connecting rod 8 to deform in an X shape, thereby pushing the lifting table 7 up or down, and the height of the detection motor 5 is adjusted.

[0035] Further, a driving motor 12 is fixedly installed on the top of the second operation table 2. The output end of the driving motor 12 is fixedly connected with a fourth threaded rod 24. The fourth threaded rod 24 is sleeved with the forward plate 23. When the driving motor 12 is started, it drives the fourth threaded rod 24 to rotate.

[0036] Further, the longitudinal adjustment assembly includes a third threaded rod 19, a connecting plate 20, a third guide rail 21, and a third slider 22. Two third guide rails 21 are fixedly connected to the top of the lifting table 7. The outer surfaces of the two third guide rails 21 are both slidably connected with third sliders 22. The top of the two third sliders 22 is fixedly connected with a connecting plate 20. The top of the connecting plate 20 is fixedly connected with the detection motor 5. The third threaded rod 19 is rotatably connected to the top of the lifting table 7. The third threaded rod 19 is sleeved with the connecting plate 20. When the third threaded rod 19 is rotated, since the third threaded rod 19 is sleeved with the connecting plate 20, the connecting plate 20 will move along the third guide rail 21, thereby driving the detection motor 5 to perform longitudinal adjustment to adapt to gearbox bodies 4 of different widths.

[0037] Further, the transverse adjustment assembly includes a first threaded rod 11, a second guide rail 17, and a second slider 18. Two symmetrically distributed second guide rails 17 are fixedly connected to the top of the first operation table 1. The outer surfaces of the two second guide rails 17 are both slidably connected with second sliders 18. The top of the two second sliders 18 is fixedly connected with the moving table 10. The first threaded rod 11 is rotatably connected to the top of the first operation table 1. The first threaded rod 11 is sleeved with the moving table 10. When the first threaded rod 11 is rotated, since the first threaded rod 11 is sleeved with the moving table 10, the moving table 10 will move along the second guide rail 17, thereby driving the gearbox body 4 to perform transverse adjustment, so that the connection end of the gearbox body 4 is closer to the output end of the detection motor 5.

[0038] Further, the clamping assembly includes a second threaded rod 14, a sliding groove 15, and a clamping block 16. Two symmetrically distributed sliding grooves 15 are formed in the top of the moving platform 10. A clamping block 16 is slidably connected inside the two sliding grooves 15. The outer surface of the moving platform 10 is rotatably connected with a second threaded rod 14. The second threaded rod 14 is threadedly sleeved with the clamping block 16. By rotating the second threaded rod 14, since the second threaded rod 14 is threadedly sleeved with the clamping block 16, the clamping block 16 will move along the sliding groove 15.

[0039] Further, a fixed block is fixedly connected to the top of the moving platform 10. The gearbox body 4 is located between the fixed block and the clamping block 16. The clamping block 16 will move along the sliding groove 15 and together with the fixed block will clamp and fix the gearbox body 4.

[0040] Further, four symmetrically distributed universal wheels 3 are fixedly installed at the bottoms of the first operating platform 1 and the second operating platform 2. The universal wheels 3 installed at the bottoms of the first operating platform 1 and the second operating platform 2 facilitate the movement and positioning of the entire test bench, increasing the flexibility and convenience of the equipment.

[0041] Working principle: When the staff needs to use this gearbox test bench, after placing the gearbox body 4 between the fixed block and the clamping block 16 on the moving platform 10, rotate the second threaded rod 14. Since the second threaded rod 14 is threadedly sleeved with the clamping block 16, the clamping block 16 will move along the sliding groove 15, and the clamping block 16 and the fixed block together will clamp and fix the gearbox body 4. When it is necessary to adjust the height of the detection motor 5 to adapt to gearbox bodies 4 of different heights, the driving motor 12 is started to drive the fourth threaded rod 24 to rotate. Since the fourth threaded rod 24 is sleeved with the forward plate 23, the forward plate 23 will move along the first guide rail 9, and at the same time drive the connecting rod 8 to deform in an X shape, thereby pushing the lifting platform 7 to rise or fall, and the height of the detection motor 5 is adjusted. In order to adjust the longitudinal distance between the connection end of the detection motor 5 and the gearbox body 4, the third threaded rod 19 can be rotated. Since the third threaded rod 19 is sleeved with the connecting plate 20, the connecting plate 20 will move along the third guide rail 21, thereby driving the detection motor 5 to perform longitudinal adjustment to adapt to gearbox bodies 4 of different widths. When the height of the connection end of the detection motor 5 and the gearbox body 4 and the corresponding positions in the left and right directions are adjusted, rotate the first threaded rod 11. Since the first threaded rod 11 is sleeved with the moving platform 10, the moving platform 10 will move along the second guide rail 17, thereby driving the gearbox body 4 to perform lateral adjustment to make the connection end of the gearbox body 4 closer to the output end of the detection motor 5. Then connect the gearbox body 4 and the detection motor 5 through the connecting sleeve 6, and start the detection motor 5 to perform various performance tests of the gearbox. The universal wheels 3 installed at the bottoms of the first operating platform 1 and the second operating platform 2 facilitate the movement and positioning of the entire test bench, increasing the flexibility and convenience of the equipment.
