DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Embodiment one

[0023] Please refer to Figures 1-4The utility model provides following technical scheme: a drive axle testing arrangement, including support 1, the top of support 1 is installed with work table 2, the top of work table 2 is connected with guard plate 3, the lateral wall of work table 2 is installed with control panel 4, the top of work table 2 is equipped with drive axle body 20, the top of work table 2 is provided with support block 5, the top of support block 5 is installed with test mechanism 6, the inside of work table 2 is equipped with two -way threaded rod 7, one end of two -way threaded rod 7 is installed with first bearing 8, one end of work table 2 is installed with drive motor 9, the surface of two -way threaded rod 7 is connected with threaded sleeve 10, the top of work table 2 is provided with support plate 11, the bottom of support 1 is installed with electric rod 12.

[0024] In the preferred embodiment, the output shaft of the drive motor 9 is connected to the other end of the two-way threaded rod 7, and the two-way threaded rod 7 is rotatably connected to the inside of the work table 2 through the drive motor 9 and the first bearing 8.

[0025] In the preferred embodiment, the top end of the threaded sleeve 10 is connected to the bottom end of the support block 5, and the support block 5 constitutes a threaded reciprocating motion between the threaded sleeve 10 and the two-way threaded rod 7.

[0026] In the preferred embodiment, the support plate 11 constitutes a lifting connection between the work table 2 and the electric rod 12.

[0027] In the preferred embodiment, the precise cooperation between the support plate 11 and the electric rod 12 provides the necessary auxiliary support for the suspended drive axle body 20, effectively reducing the weight borne by the two ends of the drive axle body 20, thereby avoiding deformation or stress concentration that may be caused by uneven weight bearing. These deformations or stress concentrations may otherwise affect the geometric precision and performance of the drive axle, thereby interfering with the precision detection results.

[0028] Specifically, through the control panel 4, the user can easily start the electric rod 12 to work. The telescopic end of the electric rod 12 extends accordingly, pushing the support plate 11 to rise until it is close to and tightly fits the bottom end of the drive axle body 20, providing stable auxiliary support for it. It is worth mentioning that the telescopic distance of the electric rod 12 can be adjusted according to actual needs, so that the support plate 11 can adapt to different sizes of drive axle bodies 20 for testing.

[0029] In addition, the control panel 4 can also start the drive motor 9. After the drive motor 9 is started, it will drive the two-way threaded rod 7 to rotate smoothly inside the work table 2 along the inner ring of the first bearing 8. With the rotation of the two-way threaded rod 7, the threaded sleeve 10 will drive the support block 5 to move closer or farther away along the threads on the surface of the threaded rod, thereby conveniently adjusting the distance between the two support blocks 5 according to the actual length of the drive axle body 20. This design enables the test mechanism 6 to be applicable to different sizes of drive axle bodies 20 for testing, greatly improving the flexibility and applicability of the test.

[0030] Embodiment two

[0031] Please refer to Figures 1-4 The front end of the workbench 2 is inserted with a baffle 13, the inside of the support 1 is installed with a fixed block 14, and the inside of the fixed block 14 is assembled with a lead screw 15.

[0032] In the preferred embodiment, the inside of the fixed block 14 is assembled with a servo motor 16, the surface of the lead screw 15 is threadedly connected with a sleeve 17, one end of the lead screw 15 is installed with a second bearing 19, and the outer side wall of the sleeve 17 is connected with a butt block 18.

[0033] In the preferred embodiment, the front end of the butt block 18 is connected with the back end of the baffle 13, the baffle 13 is threadedly connected with the lead screw 15 through the butt block 18 and the sleeve 17, and the lead screw 15 is rotationally connected in the inside of the fixed block 14 through the servo motor 16 and the second bearing 19.

[0034] In the embodiment, the ingenious combination of the protective plate 3 and the baffle 13 creates a relatively closed and stable environment for the test area of the drive axle body 20, effectively isolating external environmental interference and ensuring the accuracy and reliability of the test results. This design not only improves the accuracy of the test, but also ensures the safety and stability of the drive axle body 20 during the test process.

[0035] Specifically, the user only needs to easily start the servo motor 16 to work through the control panel 4. The output shaft of the servo motor 16 then drives the lead screw 15 to rotate in the inner ring of the second bearing 19. Then, the sleeve 17 will drive the butt block 18 to move up or down, and the movement of the butt block 18 further causes the baffle 13 to adjust the position accordingly. This design allows the baffle 13 to closely cooperate with the protective plate 3 during the test process, completely enclosing the drive axle body 20 in the relatively closed space formed by the protective plate 3 and the baffle 13, thereby effectively isolating external environmental interference. At the same time, by simply lowering the baffle 13, the user can easily remove the drive axle body 20 from the enclosure, greatly improving the convenience of operation and the flexibility of the test.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
