[0002] The CV joint is a crucial component in an automotive transmission system. It requires inspection before leaving the factory. Existing technology offers a testing device, but it can only measure the inner diameter of the CV joint, not its center height. Traditionally, the center height of the CV joint is measured using a height gauge and then calculated, which is not only cumbersome but also yields inconsistent values, requiring specialized personnel.

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Example 1:

[0022] A ball cage testing device includes a test bench and a measuring mechanism, wherein:

[0023] The measuring platform includes a fixed plate 1, four connecting columns and a measuring plate 3. The measuring plate 3 is connected to the fixed plate 1 through the four connecting columns, and the measuring plate 3 is also provided with a measuring port 2. The ball cage 25 is placed on the measuring plate 3 and located above the measuring port 2.

[0024] The measuring mechanism includes a first support 4, a first measuring element 5, a first measuring ball 6, a fixed table 7, a sliding table 8, a second support 9, a second measuring element 10, a second measuring ball 11, a rotating table, a gear 22, a first measuring gauge 12, a second measuring gauge 13, and a third measuring gauge 14, wherein:

[0025] The first bracket 4 is fixed on the fixing plate 1;

[0026] The first measuring element 5 slides vertically on the first bracket 4, and a rack 23 is provided on one side of it, and a second connecting arm 20 is fixed on the other side of the first measuring element 5.

[0027] The first measuring ball 6 has a connecting screw and is connected to the first measuring element 5 via the connecting screw;

[0028] The fixed platform 7 is fixed on the fixed plate 1;

[0029] The slide table 8 is horizontally slidably connected to the fixed platform 7, and the slide table 8 is also connected to the first connecting arm 16. The slide table 8 can be moved by controlling the first connecting arm 16.

[0030] The second bracket 9 is fixed to one side of the slide table 8, so that it can slide horizontally together with the slide table 8;

[0031] The second measuring element 10 slides vertically on the second bracket 9, and a rack 23 is also provided on one side of it;

[0032] The second measuring ball 11 is equipped with a connecting screw and is connected to the second measuring element 10 via the connecting screw;

[0033] The first measuring ball 6 and the second measuring ball 11 have the same diameter, but they face opposite directions after being installed on the measuring piece;

[0034] The rotating platform, fixed on the fixed plate 1, is U-shaped and is connected to the gear 22 for rotation.

[0035] Gear 22 is rotatably connected to the rotating table and meshes with rack 23 on the first measuring element 5 and the second measuring element 10. When gear 22 rotates, it can drive rack 23 to move, thereby driving the first measuring element 5 and the second measuring element 10 to move vertically together.

[0036] The first measuring instrument 12 is a dial indicator, which is fixed on the fixed plate 1, and its measuring head is for measuring the slide 8. In this way, the position of the slide 8 can be measured when the slide 8 moves, which is equivalent to detecting the distance between the first measuring element 5 and the second measuring element 10, and then the distance between the first measuring ball 6 and the second measuring ball 11 can be measured. That is, its measuring head is against the slide 8.

[0037] The second measuring instrument 13 is a dial indicator, which is fixed on the measuring plate 3 and is used to measure the height of the second connecting arm 20. In addition, it can measure the height of the first measuring element 5 and the second measuring element 10. That is, its measuring head is against the second connecting arm 20.

[0038] The third measuring instrument 14 is a dial indicator, which is fixed on the measuring plate 3. It is used to measure the position of the ball cage 25, which is placed on the measuring plate 3 and fixed by two measuring balls. That is, its measuring head is against the outer circumference of the ball cage 25.

[0039] The diameter of the ball cage 25 is measured mainly by controlling the movement of the slide table 8, which in turn adjusts the distance between the first measuring ball 6 and the second measuring ball 11, thereby obtaining the diameter of the ball cage 25.

[0040] The center height of the ball cage 25 can be obtained by rotating the gear 22, which drives the rack 23 to move, thereby adjusting the height of the two measuring balls. The position of the two measuring balls embedded in the groove of the ball cage 25 can also be adjusted. Finally, by using the second measuring gauge 13 and the third measuring gauge 14, the center height of the ball cage 25 can be obtained.

[0041] Example 2:

[0042] The difference from Embodiment 1 is that in Embodiment 2, an operating lever 15 is also connected to the first connecting arm 16, and a guide frame 17 is fixed on the fixing plate 1. The guide frame 17 is provided with a through hole 18. One end of the operating lever 15 is connected to the first connecting arm 16, and the other end of the operating lever 15 passes through the guide frame 17 and is connected to an operating ball 19. In this way, the user can control the position of the slide table 8 by controlling the operating ball 19, which is more convenient to control.

[0043] Example 3:

[0044] The difference from Embodiment 1 is that in Embodiment 3, the gear 22 is a gear cylinder 22, which rotates on a rotating platform, and a handle 24 is provided on one side of the gear cylinder 22. The user can easily rotate the handle 24 to rotate the gear cylinder 22, thereby controlling the vertical movement of the two measuring components.
