[0006] To achieve the above objectives, this utility model provides a fixed fixture for detecting noise and vibration in steering columns, comprising a base, a rigid column assembly, a position adjustment mechanism, and a column assembly mechanism. Two rigid column assemblies are fixed to the top two sides of the base, and a position adjustment mechanism is installed between the two rigid column assemblies. The position adjustment mechanism includes a position adjustment plate, a mounting slider, a connecting shaft, an angle adjustment shaft, a height adjustment shaft, and a connecting block. The outer sides of both position adjustment plates are provided with mounting sliders and connecting blocks. The mounting sliders are slidably connected to the rigid column assemblies. The lower end of the height adjustment shaft is connected to the connecting block, and the upper end of the height adjustment shaft is connected to the top of the rigid column assembly. A connecting shaft and an angle adjustment shaft are installed between the two position adjustment plates. The end of the connecting shaft is fixedly connected to the position adjustment plate, and the end of the angle adjustment shaft is inserted into the arc-shaped groove on the surface of the position adjustment plate and fixed with fasteners. The column assembly mechanism is installed at the bottom of the connecting shaft and the angle adjustment shaft.
[0007] The base includes a marble base and a high-carbon steel base plate. The high-carbon steel base plate is fixed to the top of the marble base, and the high-carbon steel base plate and the marble base are fixed together by bolts.
[0008] The rigid column assembly includes a column body and a crossbeam. The crossbeam is mounted on top of the two column bodies, and the surface of the column body is vertically provided with a sliding groove.
[0009] The mounting slider is slidably connected to the slide groove, and the upper end of the height adjustment shaft is connected to the crossbeam.
[0010] The aforementioned column assembly mechanism includes connecting plates and column connectors, with two column connectors installed between the two connecting plates.
[0011] The upper ends of the two connecting plates are respectively connected to the bottom of the connecting shaft and the angle adjustment shaft, and the column connector is connected to the steering column.
[0012] Compared with the prior art, this utility model uses a rigid column assembly installation position adjustment mechanism to adjust the height and angle of the column assembly mechanism, thereby meeting the noise testing requirements of the steering column at different positions and laying the foundation for improving the driving comfort of the steering system.

Figure 3The position adjustment mechanism 3 includes a position adjustment plate 31, a mounting slider 32, a connecting shaft 33, an angle adjustment shaft 34, a height adjustment shaft 35, and a connecting block 36. The outer sides of both position adjustment plates 31 are provided with mounting sliders 32 and connecting blocks 36. The mounting sliders 32 are slidably connected to the rigid column assembly 2. The lower end of the height adjustment shaft 35 is connected to the connecting block 36, and the upper end of the height adjustment shaft 35 is connected to the top of the rigid column assembly 2. The connecting shaft 33 and the angle adjustment shaft 34 are installed between the two position adjustment plates 31. The end of the connecting shaft 33 is fixedly connected to the position adjustment plate 31. After the end of the angle adjustment shaft 34 is inserted into the arc groove 311 on the surface of the position adjustment plate 31, it is fixed with fasteners. The column assembly mechanism 4 is installed at the bottom of the connecting shaft 33 and the angle adjustment shaft 34.
