In order to solve the problem that the reducer interchangeability of traditional test equipment is poor, one test equipment can only correspond to reducers of several models and sizes, and the reducer will vibrate during the test, which affects the stability of the test. The test end can select a brake with a suitable range according to actual conditions, and the test platform can be adjusted according to different models of reducers. This greatly improves the applicability of the equipment. During the test, the jitter of the reducer to be tested is reduced by a stable locking device, and the stability of the test platform is increased. Different working conditions can be simulated by adjusting the output torque of the test end.

[0035] Example 1

[0036] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, this embodiment proposes a highly adaptable reducer test device, including a frame 1, a mounting platform 4 horizontally arranged on the top of the frame 1 and positioning the reducer, a test terminal 3 located at one end of the top of the frame 1, and a connecting device 2 connecting the output terminal of the reducer to the test terminal 3. The above components belong to the prior art and have the same working principle as the reference document application number 202321444966.5, so this application will not elaborate on them.

[0037] A lifting mechanism 5 for lifting the reducer is provided at one end of the top of the frame 1 close to the mounting platform 4 and slides along the length direction. A translation component 6 for controlling the longitudinal movement of the reducer is provided at the top of the lifting mechanism 5. A stabilizing component 7 is provided at the end of the bottom of the frame 1 away from the lifting mechanism 5.

[0038] During the process of hoisting the reducer, the reducer is transported to the bottom of the frame 1 near one end of the mounting platform 4, and then the horizontal movement of the hoisting mechanism 5 is controlled to move the hoisting mechanism 5 out to the top of the reducer. The reducer is hoisted, and the center of gravity of the device shifts during the hoisting process. In order to stabilize the position of the frame 1, the stabilizing component 7 can be used to control the stability of the frame 1. At the same time, during the hoisting process, the position of the reducer is fine-tuned by the translation component 6, and the reducer is placed on the top of the mounting platform 4, connected to the connecting device 2, and the test operation is carried out.

[0039] Example 2

[0040] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0041] like Figure 2 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, the lifting mechanism 5 further includes an electric slide rail 501, an L-shaped rod 502, a support plate 503, a rotating motor 504, a wire reel 505, a lifting rope 506 and a hook 507. The electric slide rail 501 is arranged on both sides of the mounting platform 4 along the length direction of the frame 1. The interior of the electric slide rail 501 is installed with an L-shaped rod 502 through an electric slider. The support plate 503 is horizontally fixed between the top ends of the L-shaped rod 502. The top of the support plate 503 is installed with a rotating motor 504. The output end of the rotating motor 504 is installed with a wire reel 505. The lifting rope 506 is wound around the wire reel 505, and the bottom end of the lifting rope 506 is installed with a hook 507.

[0042] When hoisting the reducer, the electric slider inside the electric slide rail 501 drives the L-shaped rod 502 to move, moves the support plate 503 to the outer end of the frame 1, and places it on the top of the reducer, then starts the rotating motor 504 to drive the wire reel 505 to rotate, releases the lifting rope 506, hooks the hook 507 on the hanging ring on the reducer, and then starts the rotating motor 504 again to reel the lifting rope 506, hoist the reducer, and at the same time control the electric slider to drive the L-shaped rod 502 to move, move the reducer to the top of the mounting platform 4 and put it down, and then connect it to the connecting device 2 to carry out the test operation.

[0043] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the translation component 6 includes a slide 601, a slider 602 and a cylinder 603, the slide 601 is opened on the top of the support plate 503, and the slider 602 is slidably installed inside the slide 601, the rotating motor 504 is fixed on the top of the slider 602, the side of the support plate 503 is fixed with the cylinder 603, and the output end of the cylinder 603 is fixedly connected to the slider 602.

[0044] During the process of lifting the reducer, the cylinder 603 is started to control the slider 602 to slide inside the slide groove 601, so as to fine-tune the position of the reducer.

[0045] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, a sliding rod is symmetrically installed on the side of the slider 602 close to the cylinder 603, and the sliding rod is slidably connected to the supporting plate 503.

[0046] The use of the slide rod can ensure stability when fine-tuning the reducer.

[0047] like Figure 4As shown, as a preferred embodiment, on the basis of the above method, the stabilizing assembly 7 further includes a counterweight 701, a fixed pulley 704, a pull rope 705 and a reset member. The counterweight 701 is slidably arranged at the bottom of the frame 1, and the supporting legs of the frame 1 near one end of the counterweight 701 are all installed with fixed pulleys 704. The side of the counterweight 701 near the mounting platform 4 is fixed with a pull rope 705. The pull rope 705 passes through the bottom of the fixed pulley 704 and fits on the top of the fixed pulley 704, and the top of the pull rope 705 is fixedly connected to the bottom of the L-shaped rod 502. A reset member for controlling the reset of the counterweight 701 is provided at the bottom of the frame 1.

[0048] When the reducer is lifted, the center of gravity of the frame 1 will shift due to its weight. In order to ensure the stability of the frame 1, the pull rope 705 can be used to control the counterweight 701 to move away from the frame 1 while controlling the L-shaped rod 502 to slide outward, so as to ensure that the center of gravity of the device is always located on the frame 1. After lifting, as the L-shaped rod 502 is reset, the counterweight 701 is automatically reset under the pull of the reset member.

[0049] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, the reset member further includes a positioning plate 702 and a tension spring 703, the positioning plate 702 is vertically fixed to the bottom of the frame 1, and a tension spring 703 is installed between the positioning plate 702 and the side of the counterweight block 701.

[0050] When the counterweight 701 slides outward, the tension spring 703 is pulled. After the L-shaped rod 502 is reset, the tension spring 703 can pull the counterweight 701 to reset the counterweight 701.

[0051] Example 3

[0052] The following further describes the solutions in Example 1 and Example 2 in conjunction with specific working methods, as described below:

[0053] During the process of hoisting the reducer, the reducer is transported to the bottom of the frame 1 near the end of the mounting platform 4, and the electric slider inside the electric slide rail 501 drives the L-shaped rod 502 to move, and the support plate 503 is moved to the outer end of the frame 1 and placed on the top of the reducer. Then, the rotating motor 504 is started to drive the wire reel 505 to rotate, and the lifting rope 506 is released. The hook 507 is hooked on the hanging ring on the reducer, and then the rotating motor 504 is started again to reel the lifting rope 506 to lift the reducer. At the same time, the electric slider is controlled to drive the L-shaped rod 502 to move, and the reducer is moved to the top of the mounting platform 4. During the process of hoisting the reducer, the cylinder 603 is started to control the slider 6 02 slides inside the slide groove 601 to fine-tune the position of the reducer, then lower the reducer, connect the output shaft of the reducer to the connecting device 2, and perform test operations. In addition, when the reducer is lifted, since the reducer has a certain weight, it will cause the center of gravity of the frame 1 to shift. In order to ensure the stability of the frame 1, while controlling the L-shaped rod 502 to slide outward, the pull rope 705 can be used to control the counterweight block 701 to move away from the frame 1, and the tension spring 703 can be stretched to ensure that the center of gravity of the device is always located on the frame 1. After lifting, as the L-shaped rod 502 is reset, the counterweight block 701 is automatically reset under the pull of the tension spring 703.

[0054] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
