Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Combination Figure 1-3 As shown, a test platform for automotive suspension torsion bars includes a support frame 1. Clamping devices 2 are provided on both sides of the upper end of the support frame 1. A movable frame 3 is provided on one side of the upper end of the clamping device 2. A measuring device 4 is provided on one side of the upper end of the movable frame 3. A torsion bar 5 is clamped at the upper end of the clamping device 2. The clamping device 2 includes a fixed plate 21. A sliding groove 22 is provided on the fixed plate 21. A pushing clamping head 23 is provided on the sliding groove 22. A pushing clamping head 24 is provided on one side of the upper end of the pushing clamping head 23. A contour clamping head 25 is provided on one side of the upper end of the fixed plate 21. Locking bolts 2 are provided at all four corners of the fixed plate 21. 6. The clamping device adopts a design of fixed plate and contour clamping head, which can accurately clamp the torsion bar according to its shape, ensuring that the torsion bar does not loosen or deform during the test, thereby improving the accuracy and reliability of the test results. The clamping position of the clamping device can be adjusted by the sliding groove and the push clamping head setting, so that the platform can adapt to torsion bars of different sizes and specifications, and has stronger versatility and applicability. The combination of the moving frame and the measuring device allows the platform to move and measure accurately according to the needs, ensuring that data at each angle and position are accurately collected, meeting the needs of multi-angle testing.
[0020] The measuring device 4 includes a transverse slide rail 41, a transverse slider 42 slidably connected to the transverse slide rail 41, a longitudinal slide rail 43 fixedly connected to the transverse slider 42, a longitudinal slider 44 movably connected to the longitudinal slide rail 43, and a measuring instrument 45 fixedly connected to the longitudinal slider 44. The measuring device adopts a dual sliding system of transverse and longitudinal slide rails, which can move freely in two directions, enabling the measuring instrument to achieve accurate measurements at multiple angles and dimensions, meeting various testing needs, and is especially suitable for occasions requiring fine adjustment of the measurement position. The transverse slide rail 41 is fixedly connected to the moving frame 3. A pressure sensor is also provided on one side of the upper end of the clamping device 2 to detect the magnitude of the clamping force and ensure that the torsion bar is clamped under appropriate force. Silicone sleeves are used on the contour clamping head 25 and the pushing clamping head 23 to prevent damage to the torsion bar during clamping.
[0021] Working principle: The torsion bar 5 to be tested is placed between the two clamping devices 2. The contour of the contoured clamping head 25 matches the shape of the end of the torsion bar, and it is initially fitted and fixed. The clamping head 23 is pushed to move laterally through the slide groove 22. With the fine adjustment of the push bolt 24, the clamping distance can be precisely adjusted to ensure that the axis of the torsion bar coincides with the center line of the test platform. The clamping device has a built-in pressure sensor to monitor the clamping force in real time. The operator adjusts the push bolt 24 according to the preset threshold to avoid the torsion bar being deformed due to excessive clamping or slipping due to excessive looseness. The flexible contact of the silicone sleeve The design can disperse local pressure and protect the surface coating or structural integrity of the torsion bar. The measuring device 4 is close to the area of the torsion bar being measured. Through the combined movement of the transverse slide rail 41 and the longitudinal slide rail 43, the measuring instrument 45 is driven to be precisely positioned in the XY plane with a minimum step accuracy of 0.1mm. The measuring instrument 45 uses the pitch adjustment function of the longitudinal slider 44 to keep the probe axis perpendicular to the surface of the torsion bar being measured, eliminating measurement errors caused by the installation tilt angle. The measuring device 4 is moved laterally by external drive to measure the bending degree of the torsion bar.
