[0019] Pulleys 26 are fixedly installed on the outside of the two first rotating shafts 25, and the external movable sleeves of the two pulleys 26 are provided with the same transmission belt 27. A slide groove 20 is opened on the inner side of each support column 2, and each first moving block 23 is slidably engaged in the slide groove 20. By setting the slide groove 20, the first moving block 23 is limited. At the same time, the first moving block 23 is made more stable when moving. A motor 28 is fixedly installed on the bottom end of the test bench 1, and the driving end of the motor 28 is fixedly installed on the end of one of the first rotating shafts 25. By setting the motor 28, when the motor 28 is started, it drives one of the first rotating shafts 25 to rotate, thereby driving the corresponding double-headed screw 22 to rotate.

[0020] A second rotating shaft 3 is rotatably penetrated on one side of the first movable plate 24 located below and away from the test motor 12. A main bevel gear 31 is fixedly installed on one side of the second rotating shaft 3. Both sides of the main bevel gear 31 are meshedly connected with slave bevel gears 32. Threaded rods 33 with the same threads are fixedly installed on the opposite ends of the two slave bevel gears 32. The outer side of each threaded rod 33 is threadedly connected with a second movable block 34. The top of the second movable block 34 is fixedly installed with a second movable plate 35. The second movable plate 35 is in contact with the first movable plate 24. The second rotating shaft 3 is far away from the test motor 12. A rotating wheel 38 is fixedly installed on one side away from the main bevel gear 31, and a plurality of anti-skid strips evenly distributed in an annular shape are fixedly installed on the outside of the rotating wheel 38. A slot 36 is provided on the side of the first movable plate 24 located below and close to the main bevel gear 31. The second movable block 34 is slidably engaged in the slot 36. A fixed seat 37 is rotatably sleeved on the outside of the two threaded rods 33. The fixed seat 37 is fixedly installed on the inner wall of the slot 36. By setting the slot 36, the second movable block 34 is limited. At the same time, the second movable block 34 is more stable when moving.

[0021] A placement groove 4 is provided at the edge of the upper surface of the first movable plate 24 below, and a ruler plate 41 is fixedly installed inside the placement groove 4. By setting the ruler plate 41, it is convenient to adjust the distance between the second movable plate 35 and the second movable block 34 according to the size of the corresponding gear box, so that the gear box can be placed at the center position of the first movable plate 24 more accurately, which is convenient for testing that the output shaft of the motor 12 is aligned with the input shaft of the gear box.

[0022] A hydraulic telescopic rod 5 is fixedly installed on one side of the top of the test bench 1 close to the mounting plate 11, and the driving end of the hydraulic telescopic rod 5 is fixedly installed on the mounting plate 11. Two symmetrically distributed slide rails 51 are fixedly installed on the top of the test bench 1, and the mounting plate 11 is slidably connected to the slide rails 51. By setting the hydraulic telescopic rod 5, when the hydraulic telescopic rod 5 is started, it drives the mounting plate 11 and the test motor 12 to move toward the gear box input shaft on the slide rail 51, so that the output shaft of the test motor 12 is connected to the gear box input shaft, thereby realizing the drive of the test motor 12 to test the gear box.

[0023] A baffle 6 is fixedly installed on the edge of the side away from the rotating wheel 38 at the top of the first movable plate 24 at the bottom, and a rubber pad 61 is fixedly installed on the side of the baffle 6 close to the rotating wheel 38. By setting the baffle 6, when placing the gear box, you can know where to push it, so there is no need to push the gear box forward, which improves the placement of the gear box.

[0024] Working principle: In actual use, the gear box is placed on the top of the first movable plate 24 located below, and then the corresponding double-headed screw 22 is driven to rotate by the rotation of one of the first rotating shafts 25. The rotation of one of the first rotating shafts 25 drives the corresponding pulley 26 to rotate, and the pulley 26 drives the transmission belt 27 to rotate, thereby driving the other pulley 26 to rotate. The two pulleys 26 and the transmission belt 27 are used in coordination to drive the other first rotating shaft 25 and the double-headed screw 22 to rotate at the same time, and then the two double-headed screws 22 rotate at the same time, driving the corresponding first moving block 23 and the first moving plate 24 to move toward the middle. When the upper and lower first moving plates 24 are fitted with the gear box, it means that the input shaft of the gear box corresponds to the output shaft of the test motor 12, and no adjustment is required.

[0025] When gear boxes of different sizes are placed on the first movable plate 24 located below, the distance between the two second movable plates 35 is adjusted according to the size of the gear box. Specifically, the second rotating shaft 3 is rotated to drive the main bevel gear 31 to rotate, thereby driving the slave bevel gears 32 on both sides to rotate. The main bevel gear 31 and the slave bevel gear 32 cooperate with each other to drive the corresponding threaded rod 33 to rotate at the same time. As the threaded rod 33 rotates, the corresponding second movable block 34 and the second movable plate 35 are driven to move toward the middle, so that the distance between the second movable plates 35 is almost the same as the size of the gear box. Then the gear box is placed in the middle of the first movable plate 24. When the output shaft of the test motor 12 and the center position of the gear box input shaft are aligned, the hydraulic telescopic rod 5 is started to drive the mounting plate 11 and the test motor 12 to move toward the gear box input shaft on the slide rail 51, so that the output shaft of the test motor 12 is connected to the gear box input shaft, and finally the drive of the test motor 12 tests the gear box.

[0026] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
