[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figures 1-2 As shown, this application provides a dynamic torque sensor testing fixture with a test object 5. The testing fixture includes a flexible platform 2, a motor bracket 3 is fixedly installed on the upper end of the flexible platform 2, a servo motor 1 is fixedly installed on the motor bracket 3, and the servo motor 1 has an output shaft that passes through the motor bracket 3.

[0028] Meanwhile, a coupling 4 is fixedly installed on the output shaft of the servo motor 1. The coupling 4 is adapted to the measured object 5. In this application, the coupling 4 can be replaced to adapt to measuring different models of products.

[0029] Furthermore, the flexible platform 2 is also provided with a slide rail 9, which is located on the side of the motor bracket 3 away from the servo motor 1. A slider 10 is slidably connected to the slide rail 9, and an adapter plate 11 is fixedly installed on the upper end of the slider 10. A three-axis fine-tuning platform 7 is fixedly installed on the upper end of the adapter plate 11. Therefore, the position of the three-axis fine-tuning platform 7 can be adjusted by the adapter plate 11 sliding in one direction with the slider 10 within the slide rail 9, and the coaxiality of the three-axis fine-tuning platform 7 and the coupling 4 can be ensured during the movement.

[0030] The upper surface of the three-axis fine-tuning platform 7 is fixedly mounted with a fixture plate 6, which is used to mount the test object 5. In this application, the three-axis fine-tuning platform 7 is the prior art. The test object 5 on the fixture plate 6 can be finely adjusted in the XYZ directions by the three-axis fine-tuning platform 7 to ensure that the test object 5 is coaxially connected with the coupling 4.

[0031] Meanwhile, a base plate 12 is provided at the lower end of the flexible platform 2, and a support foot 13 is fixedly installed between the base plate 12 and the flexible platform 2. The support foot 13 is used to buffer the flexible platform 2 to ensure the stability of the flexible platform 2.

[0032] In this application, the height of the support leg 13 is adjustable, so the flexible platform 2 can be made horizontal by adjusting the support leg 13.

[0033] A protective cover 8 is also fixedly installed on the upper end of the flexible platform 2. The protective cover 8 is located on the outside of the tested object 5 and the three-axis fine-tuning platform 7, thus protecting them.

[0034] like Figure 3 As shown, mounting holes 14 are provided on both sides of the fixed fixture plate 6. A slide rod 15 is slidably connected in the mounting hole 14. A clamping plate 17 is fixedly installed on the outer end of the slide rod 15. The clamping plate 17 is set on both sides of the test object 5. A spring 16 is fixedly installed between the clamping plate 17 and the fixed fixture plate 6. The spring 16 is sleeved on the outside of the slide rod 15. During installation, the test object 5 pushes the clamping plate 17 outward, causing the spring 16 to stretch. When the test object 5 is placed on the fixed fixture plate 6, the contraction force of the spring 16 will cause the clamping plate 17 to stick to the surface of the test object 5, thus ensuring the stability of the test object 5 during testing.

[0035] In summary: When supporting the test object 5, the test object 5 is first clamped between the clamping plates 17, and then the test object 5 is made coaxial with the coupling 4 by the three-axis fine adjustment platform 7. Then, the adapter plate 11 is moved to make the test object 5 and the coupling 4 fit together and install. Finally, the test object 5 is tested by starting the servo motor 1 to observe whether its output is stable at a specific speed.

[0036] Therefore, the use of fewer parts in this test fixture makes the assembly of the test object 5 simple, easy to carry, and flexible to adjust. It is suitable for different occasions and can also adapt to products with various ranges and sizes.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
