Problems solved by technology
However, the nut with this structure has the following defects: 1. The radial adjustable amount of the nut in the nut box is small; 2. The nut cannot be fixed in the nut box and can rotate around the thread centerline; 3. Increased axial positioning and radial positioning The ring part makes the overall structure complex and requires high assembly, which is not conducive to mass production; 4. The adjustment of the nut cannot play a role in limiting the space limit of the installed parts
The problem with this structure is that the nut can only be adjusted in the accommodation cavity, and cannot move with the accommodation cavity as a whole to limit the space

Embodiment Construction
[0024] figure 1 It is a structural schematic diagram of the present invention, figure 2 for figure 1 Schematic diagram of the cross-sectional structure of the structure shown. Depend on figure 1 and figure 2 It can be seen from the combination that the nut installation structure used for the instrument panel beam includes a base nut 1 and a moving nut 2 nested inside the base nut 1. The base nut 1 is provided with internal threads, and the moving nut 2 is provided with internal threads. There are external threads and internal threads, and the external threads on the moving nut 2 cooperate with the internal threads on the base nut 1, that is, the moving nut 2 is installed on the base nut 1, and the counterclockwise rotation is screwed in, and the clockwise Rotate to spin out.

The invention discloses a nut mounting structure used for a instrument panel beam, which comprises a substrate nut and a moving nut embedded in the substrate nut; the substrate nut is provided with internal threads; the moving nut is provided with external threads and internal threads; moreover, the external threads on the moving nut are matched with the internal threads of the substrate nut; the moving nut is arranged on the substrate nut, is screwed in by rotating anticlockwise and is screwed out by rotating clockwise; the substrate nut is welded on the beam end plate of the vehicle instrument panel; the moving nut is arranged on the substrate nut and is positioned between the beam end plate and the body stamping; and a certain gap d is reserved between the moving nut and the body stamping during design and is greater than the actual tolerance between the moving nut and the body stamping. The special nut mounting structure eliminates the influence of the dimensional tolerance of the left and right lateral assemblies of the vehicle body in the Y direction on the matching by the screwed-out distance of the moving nut so as to meet the assembly requirement.
Description
technical field [0001] The invention relates to a nut installation structure, in particular to a nut installation structure with an adjustable axial dimension used on an instrument panel beam. Background technique [0002] For the assembly requirements of various instrument panel beams, especially the instrument panel beams whose sides are fixed in the Y direction, a certain amount of adjustment is required during the product assembly process to achieve good matching requirements. The traditional method is to directly weld ordinary nuts on the end plates on both sides of the beam. The position of this welding method cannot be adjusted. Due to the manufacturing errors, welding errors and assembly errors of the body side wall, the accumulation of these errors will eventually lead to the failure of parts. If it is assembled smoothly or the fit is not good after assembly, the whole will be shifted to one side, which will affect the performance and appearance of the assembly. ...
