[0019] like Figure 1-4 As shown, the utility model proposes a detection machine for automobile steering wheel buttons, including a base 1, a bracket 2, a pressure test piece 3 and a fixing assembly 4, wherein the bracket 2 is arranged on the base 1, and the bracket 2 is arranged in a U-shaped structure, the pressure test piece 3 is arranged on the bracket 2, and the fixing assembly 4 is arranged on the base 1; the fixing assembly 4 includes a limit plate 5, a moving block 6 and a driving member 7, and the two side walls of the limit plate 5 are provided with connecting columns 8, and the connecting columns 8 are arranged on the inner side wall of the bracket 2, and the limit plate 5 is provided with a plurality of slide grooves 9 in the radial direction, and the moving block 6 is slidably arranged on the slide groove 9, and the side wall of the moving block 6 is provided with an anti-slip pad 23, and the driving member 7 is arranged on the base 1 and below the limit plate 5, and the steering wheel is placed on the limit plate 5, and the driving member 7 drives the multiple moving blocks 6 to approach each other to clamp the steering wheel to achieve fixation, and the pressure test piece 3 tests the buttons on the steering wheel.

[0020] The driving member 7 includes a rotating shaft 10 and a rotating disk 11. The bottom end of the rotating shaft 10 is rotatably arranged on the base 1, and the top end of the rotating shaft 10 is rotatably arranged on the bottom wall of the limiting disk 5. The rotating disk 11 is fixedly sleeved on the rotating shaft 10. A driving groove 12 is provided on the rotating disk 11. The driving groove 12 is an arc-shaped structure. One end of the driving groove 12 is close to the center of the rotating disk 11, and the other end of the driving groove 12 is close to the edge of the rotating disk 11. A sliding column 13 is provided at the bottom end of the moving block 6. The sliding column 13 is slidably arranged in the driving groove 12. When the rotating shaft 10 is driven to rotate, the rotating disk 11 rotates, and the driving groove 12 on the rotating disk 11 drives the sliding column 13 at the bottom of the moving block 6 to slide in the driving groove 12. At the same time, the sliding column 13 drives the moving block 6 to slide in the sliding groove 9 to clamp or move away from the steering wheel.

[0021] The rotating shaft 10 is provided with a power member 14, and the power member 14 includes a worm wheel 15 and a worm 16. The worm wheel 15 is fixedly sleeved on the rotating shaft 10. The base 1 is provided with a support plate 17. Both ends of the worm 16 are rotatably provided on the support plate 17. The worm 16 is cooperatively connected with the worm wheel 15.

[0023] During specific use, the steering wheel is placed on the limit plate 5, and the handle 18 is rotated to drive the worm 16 to rotate, the worm 16 drives the worm wheel 15 to rotate, the worm wheel 15 drives the rotating shaft 10 to rotate, the rotating shaft 10 drives the rotating disk 11 to rotate, and the driving groove 12 on the rotating disk 11 drives the sliding column 13 at the bottom of the moving block 6 to slide in the driving groove 12, and at the same time, the sliding column 13 drives the moving block 6 to slide in the sliding groove 9 to clamp the steering wheel. At the same time, the self-locking property of the worm wheel 15 and the worm 16 can be used to position the rotating disk 11, that is, the moving block 6 can be positioned to achieve fixation.

[0024] When the electric telescopic rod 19 is extended, the pressure head 21 moves down to perform a reciprocating pressure test on the buttons on the steering wheel, and observes whether the value of the force sensor 20 changes each time it is pressed, so as to test whether the steering wheel buttons fail due to long-term reciprocating pressing.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
