They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the utility model.

[0034] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "installed," "disposed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] As shown in the figure, the utility model includes a support mechanism 1, a power output mechanism located on the support mechanism 1, and a universal wheel 5 is provided below the support mechanism 1, wherein the support mechanism 1 can be either a fixed structure for carrying the power output mechanism or a liftable mechanism. In this example, the support mechanism 1 is preferably, but not limited to, a liftable mechanism, preferably implemented by a hydraulic forklift in the prior art, wherein the positioning box 6 of the plane adjustment assembly 4 is fixedly connected to the position of the fork of the hydraulic forklift. The power output mechanism includes a plane adjustment assembly 4 connected to the support mechanism 1, an angle adjustment assembly 2 connected above the plane adjustment assembly 4, and a power output assembly 3 connected to the angle adjustment assembly 2, wherein the power output assembly 3 includes a drive motor 29 and a universal coupling 30 connected to the drive motor 29. The reducer to be tested is connected to the servo drive motor 29 through the universal coupling 30, and the drive motor 29 can adjust the height and angle to adapt to the test operations of different machines.

[0036] The plane adjustment assembly 4 includes a positioning box 6 connected to the support structure, an X-axis adjustment unit and a Y-axis adjustment unit located on the positioning box 6. The X-axis adjustment unit includes an X-axis screw 11 rotatably connected to the positioning box 6, an X-axis adjustment block 14 threadedly connected to the X-axis screw 11, an X-axis movable plate 9 fixedly connected above the X-axis adjustment block 14, and an X-axis guide rail 8 slidably connected to the X-axis movable plate 9. The X-axis guide rail 8 is fixedly mounted on the positioning box 6 and is parallel to the vertical projection of the X-axis screw 11. The end of the X-axis screw 11 passes through the positioning box 6 and is equipped with an X-axis adjustment handwheel. The Y-axis adjustment unit includes a Y-axis screw 10 rotatably connected to the top of the X-axis movable plate 9, a Y-axis adjustment block 13 threadedly connected to the Y-axis screw 10, a Y-axis movable plate 12 fixedly connected to the top of the Y-axis adjustment block 13, and a Y-axis guide rail 7 slidably connected to the Y-axis movable plate 12, wherein the Y-axis guide rail 7 is fixedly installed above the X-axis movable plate 9, and a Y-axis adjustment handwheel is installed at the end of the Y-axis screw 10. In this example, positioning plates are fixedly connected on both sides of the top of the X-axis movable plate 9 to support the rotation of the Y-axis screw 10, and the Y-axis guide rail 7 is parallel to the vertical projection of the Y-axis screw 10. In this example, the sliding fit relationship between the X-axis movable plate 9 and the X-axis guide rail 8, and between the Y-axis movable plate 12 and the Y-axis guide rail 7 is realized by the principle of a slider / slide rail, and the X-axis screw 11 is perpendicular to the vertical projection of the Y-axis screw 10, so that the power output assembly 3 can be moved and adjusted in the X / Y direction on the plane.

[0037] It should also be noted that in this example, the structural principle of the top screw in the prior art can also be used to act on the guide rail to achieve locking of the X-direction moving plate 9 and the Y-direction moving plate 12 after adjustment. It can also be achieved through the following implementation methods. Specifically, locking members are respectively provided between the X-direction movable plate 9 and the X-direction guide rail 8, and between the Y-direction movable plate 12 and the Y-direction guide rail 7. The locking members include a locking block 16 fixedly connected to the X-direction movable plate 9 and the Y-direction movable plate 12, a locking screw 17 rotatably connected to the locking block 16, and two clamping blocks 18 located in the locking block 16. The two clamping blocks 18 are respectively located on both sides of the X-guide rail 8 or the Y-guide rail 7. The locking block 16 is provided with a locking groove 15, and the locking screw 17 is rotatably connected to the locking groove 15. The structure of the locking groove 15 is adapted to the clamping block 18, limiting the rotation of the clamping block 18 so that the clamping block 18 cannot rotate with the locking screw 17, and the two clamping blocks 18 can slide in the locking groove 15. The two clamping blocks 18 are respectively threadedly connected to the locking screw 17, and the internal threads of the two clamping blocks 18 have opposite thread directions. A locking handwheel or locking wrench is provided at the end of the locking screw 17. By turning the locking screw 17, the two clamping blocks 18 with opposite internal thread directions clamp the guide rails, thereby locking the X-direction moving plate 9 and the Y-direction moving plate 12 after adjustment.

[0038] The angle adjustment assembly 2 includes two base plates 19 relatively fixedly connected to the top of the Y-moving plate 12, two rotating shafts 23 respectively connected to the two base plates 19, a mounting box 27 fixedly connected between the two rotating shafts 23, a rotation adjustment portion connected to the rotating shaft 23, and a locking structure 20 arranged between the mounting box 27 and the base plates 19, and the power output assembly 3 is installed in the mounting box 27. The rotation adjustment portion can drive the rotating shaft 23 to rotate by a hand-cranked wheel 22, and is used to adjust the angle of the power output assembly 3 at the mounting box 27 to adapt to the shaft output mode of different reducer gearboxes being tested. In this example, the rotation adjustment portion includes a hand-cranked wheel 22 and a reducer (preferably a hollow reducer 21), and the reducer is connected to the rotating shaft 23. This structural design belongs to the prior art, so it will not be repeated in the embodiments of this application.

[0039] The locking structure 20 includes a locking screw 28 fixedly connected to the mounting box 27, a locking wrench 25 threadedly connected to one end of the locking screw 28, and a locking disk 24 sleeved on the locking screw 28. The surface of the base plate 19 is provided with an arcuate channel 26. The structure of the arcuate channel 26 is designed based on the trajectory of the locking screw 28 when the mounting box 27 rotates. The locking screw 28 is arranged through the arcuate channel 26 on the base plate 19. When the mounting box 27 rotates between the two base plates 19, the locking screw 28 moves within the arcuate channel 26. In this example, the locking structure 20 is provided on both sides of the base plate 19. Rotating the locking wrench 25 causes the locking disk 24 to tightly abut the outer side of the base plate 19, thereby achieving angular locking of the power output assembly 3.

[0040] The power output assembly 3 includes a drive box 32 disposed in the mounting box 27, a drive motor 29 mounted in the drive box 32, and a universal joint 30 connected to the drive motor 29. A protective cover 31 is provided on the outside of the universal joint 30. The protective cover 31 is a sliding sleeve structure. In this example, a three-stage telescopic protective cover structure is adopted. Specifically, a first casing is fixedly connected to one side of the drive box 32. A second casing is provided on the outer surface of the first casing, and a third casing is provided on the outer surface of the second casing. A first guide rail and a second guide rail are provided on the top of the drive box 32. The first guide rail is slidably connected to the first connecting plate via a slider, and the second guide rail is slidably connected to the second connecting plate via a slider. The first connecting plate is connected to the second casing, and the second connecting plate is connected to the third casing. The sliding and telescopic movement of the protective cover 31 protects the connection between the universal joint 30 and the reducer under test.

[0041] In addition, in this example, a fine-tuning structure can be installed between the installation box 27 and the drive box 32. The fine-tuning structure drives the drive box 32 for adjustment by a hand-cranked screw, specifically including a fine-tuning screw 36 that is rotatably connected to the top of the bottom plate of the installation box 27, a fine-tuning block 35 that is threadedly connected to the fine-tuning screw 36, and a fine-tuning guide rail 33 that is axially arranged along the fine-tuning screw 36. The top of the fine-tuning block 35 is fixedly connected to the bottom of the drive box 32, the fine-tuning guide rail 33 is fixedly connected to the top of the bottom surface of the installation box 27, and the bottom of the drive box 32 is slidably connected to the fine-tuning guide rail 33 through a slider. At the same time, a linear channel 37 is opened on the bottom surface of the installation box 27 along the axial direction of the fine-tuning screw 36, and the lower part of the fine-tuning block 35 is fixedly connected to the fastening screw. The fastening screw passes through the linear channel 37 and is threadedly connected to the fastening wrench 34. The outer sleeve of the fastening screw is provided with a fastening disk 38. By tightening the fastening wrench 34, the fastening disk 38 is tightly abutted against the lower surface of the installation box 27 to achieve fine-tuning locking of the power output component 3.

[0042] The utility model adjusts the position and angle of the power output component according to the specifications of the reducers to be tested and the angle of the reducer main shaft through the arrangement of the plane adjustment component and the angle adjustment component, and connects the servo drive motor to the reducer to be tested through the universal joint, so that the device is suitable for testing operations of different reducers, has strong adaptability, effectively broadens the scope of use of the test device, can be used as a standard part in multiple scenario modes, and has great market application prospects.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
