[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a gearbox assembly testing device, comprising:

[0024] A base 1, the upper surface of the base 1 is fixedly connected to a support plate 2, the upper surface of the support plate 2 is fixedly connected to a load-bearing plate 3, two fixing mechanisms, the fixing mechanism includes a fixing component and two applicable components, the fixing component includes a bidirectional threaded rod 4 arranged above the base 1, the bidirectional threaded rod 4 is rotatably connected to the side wall of the support plate 2 through a bearing, and two limiting slide grooves 5 are provided on the upper surface of the load-bearing plate 3, and nuts 6 are threadedly connected on the threaded sections of the bidirectional threaded rod 4 with opposite thread directions, and limiting sliders 7 are slidably connected in the two limiting slide grooves 5, and the bottom ends of the two limiting sliders 7 are respectively fixedly connected to the side walls of the two nuts 6, and the upper surfaces of the two limiting sliders 7 are A clamping plate No. 8 is fixedly connected, and the applicable components include a clamping plate No. 9 which is slidably connected to the upper surface of the bearing plate 3. The side wall of the clamping plate No. 9 is fixedly connected with two guide rods 10. The two guide rods 10 penetrate the side wall of the clamping plate No. 8 and are slidably connected. Two springs 11 are fixedly connected between the clamping plate No. 8 and the clamping plate No. 2, 9. The multiple springs 11 are respectively sleeved on the multiple guide rods 10. The two applicable components in each fixing mechanism are symmetrically arranged about the bearing plate 3; the two fixing components also move synchronously when the fixing mechanism is running, and the side end of any one of the two bidirectional threaded rods 4 is fixedly connected with a rotating handle, which is convenient for the staff to operate;

[0025] The synchronous component is arranged between the two fixing mechanisms. The synchronous component includes a synchronous wheel 12 which is circumferentially fixedly connected to the two bidirectional threaded rods 4. A synchronous belt 13 is meshed between the two synchronous wheels 12. The two synchronous wheels 12 are respectively concentrically arranged with the two bidirectional threaded rods 4.

[0026] The detailed working process of the utility model is as follows:

[0027] When in use, when it is necessary to fix the gearbox assembly with test, first place the gearbox assembly on the upper surface of the carrier plate 3 and between the two No. 2 clamps 9 in each fixing mechanism, then rotate the bidirectional threaded rod 4 by turning the handle. Here, a fixing mechanism is taken as an example. When the bidirectional threaded rod 4 rotates, the two nuts 6 will be threadedly engaged with the bidirectional threaded rod 4 under the restriction of the limiting slide groove 5 and the limiting slider 7, and then the two nuts 6 will move toward each other along the bidirectional threaded rod 4. When fixing is required, the two nuts 6 approach each other, and then the two No. 1 clamps 8 are driven to approach each other through the two limiting sliders 7. The two No. 1 clamps 8 drive the two No. 2 clamps 9 to approach each other through multiple guide rods 10 and springs 11 to achieve clamping and fixing of the gearbox assembly;

[0028] When a bidirectional threaded rod 4 rotates, the synchronous wheel 12 on the bidirectional threaded rod 4 rotates, thereby driving the other synchronous wheel 12 and the bidirectional threaded rod 4 to rotate through the meshing transmission of the synchronous belt 13, so that the two fixing mechanisms can be operated synchronously. The two No. 2 clamps 9 in each fixing mechanism are close to each other to achieve clamping and fixing. Even if the front and rear sizes are different, under the action of the spring 11 between the No. 2 clamp 9 and the No. 1 clamp 8, the applicability of the fixing mechanism is improved. Even if the shape is not very regular, it is still applicable. While achieving convenient operation, it also has good stability and practicality.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
