The utility model relates to the technical field of automobiles, in particular to a gap adjusting nut assembly of a crossbeam of an instrument panel of an automobile. The gap adjusting nut assembly comprises a fixing clamp clamped on the main crossbeam of the instrument panel, a fixing nut is fixedly sleeved in the fixing clamp sleeve, a rotating bolt is nested in the fixing nut, threads of the rotating bolt and threads of the fixing nut are left-handed threads, the rotating bolt is provided with a through hole, a connecting bolt matched with the through hole is connected into the through hole, a bolt head of the connecting bolt is attached onto a metal plate of an automobile body, and threads of a threaded rod of the connecting bolt and threads in the through hole of the rotating bolt are right-handed threads. A local structure of the main crossbeam of the instrument panel is optimized, left-handed thread structures of the rotating bolt and the fixing nut are designed, a gap between the main crossbeam of the instrument panel and the body in white is adjusted, the problem of an installation gap caused when the instrument panel is installed is solved, the gap adjusting nut assembly is simple in processing and convenient to implement, and other structures and appearances are not affected.
Description
Technical field
The utility model relates to automobile technical field, refers to particularly a kind of fascia board girder gap adjustment nut assembly.
Background technique
The dashboard cross member assembly is the structural member that provides support for parts such as instrument panel gadget assembly and annex thereof, occupant-side safety airbag, steering column, air-conditioning box, wire harness, simultaneously also be auxiliary clamp and the positioning supporting part in the modularization panel assembly assembly process, and and other safety members consist of together the cockpit safety system, its strength and stiffness is the primary index of its performance.
The dashboard cross member assembly directly is connected with vehicle body, bears and supports and the load of union piece transmission, and member's Security is had a great impact.For panel assembly is assembled on the vehicle body smoothly, need to leave assemblage gap between instrument panel main beam (being called for short CCB) and the body in white, make it in assembly process, have certain controlled variable, reached good cooperation requirement.Traditional settling mode is directly to weld the generic connectivity nut on the end plate of CCB both sides, the position of this welding manner is non-adjustable, after finishing assembling between CCB and the body in white, cause the gap between CCB and the body in white not eliminate, of long duration, connecting bolt is loosening easily, and easily there is potential safety hazard in the easy left and right sides of CCB play.
The model utility content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, and a kind of fascia board girder gap adjustment nut assembly that solves the assemblage gap problem that exists between instrument panel main beam and the body in white is provided.
The technical solution of the utility model is: a kind of fascia board girder gap adjustment nut assembly, comprise card and the fixedly cutting ferrule on the instrument panel main beam, fixed cover is provided with set screw nut in the described fixedly cutting ferrule, set screw nut has been nested with swivel bolt, the screw thread of swivel bolt and set screw nut is anti-silk screw thread, swivel bolt is provided with through hole, be connected with the connecting bolt that matches with it in the through hole, the bolt head of connecting bolt is close on the vehicle body sheet metal, and the screw thread in the screw portion of connecting bolt and the through hole of swivel bolt is positive silk screw thread.
Working principle of the present utility model is: at first the set screw nut in the fascia board girder gap adjustment nut assembly is set in fixedly in the cutting ferrule, then fixing cutting ferrule is connected on the instrument panel main beam, subsequently swivel bolt is nested in the set screw nut, connecting bolt is installed at last, the bolt head of connecting bolt is close on the vehicle body sheet metal, and the screw portion of connecting bolt penetrates in the through hole of swivel bolt.Because the screw thread in the screw portion of connecting bolt and the through hole of swivel bolt is positive silk screw thread, the screw thread of swivel bolt and set screw nut is anti-silk screw thread, when continuing to be rotatably connected bolt, swivel bolt can be along the direction rotation opposite with the connecting bolt rotation, after the torque spanner of connecting bolt reaches preset value, swivel bolt stops operating, at this moment, swivel bolt one end is close to vehicle body sheet metal, the other end still is enclosed within the set screw nut, has namely realized making the gap between instrument panel main beam and the body in white to obtain filling.
The utility model has been optimized the partial structurtes of instrument panel main beam, the design of the anti-silk structure by swivel bolt and set screw nut, regulated the gap between instrument panel main beam and the body in white, solved the assemblage gap problem of bringing when instrument panel is installed, and processing is simple, be convenient to realize, do not affect other structures and outward appearance.

Fig. 1 is the utility model overall structure exploded perspective view.
Fig. 2 is the structural representation of the utility model under the use state.
Fig. 3 is the structure cross-sectional schematic of the utility model under the use state.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
A kind of fascia board girder gap adjustment nut assembly as shown in FIG., comprise card and the fixedly cutting ferrule 2 on instrument panel main beam 5, fixedly cutting ferrule 2 interior fixed covers are provided with set screw nut 3, set screw nut 3 has been nested with swivel bolt 1, swivel bolt 1 is anti-silk screw thread a with the screw thread of set screw nut 3, swivel bolt 1 is provided with through hole 6, be connected with the connecting bolt 4 that matches with it in the through hole 6, the bolt head of connecting bolt 4 is close on the vehicle body sheet metal 7, and the screw thread in the through hole 6 of the screw portion of connecting bolt 4 and swivel bolt 1 is positive silk screw thread b.
The working principle of present embodiment is:
At first the set screw nut 3 in the fascia board girder gap adjustment nut assembly is set in fixedly in the cutting ferrule 2, then by fixing cutting ferrule 2 self with clamp be connected on the instrument panel main beam 5, subsequently swivel bolt 1 is nested in the set screw nut 3, connecting bolt 4 is installed at last, the bolt head of connecting bolt 4 is close on the vehicle body sheet metal 7, and the screw portion of connecting bolt 4 penetrates in the through hole 6 of swivel bolt 1.Because the screw thread in the screw portion of connecting bolt 4 and the through hole of swivel bolt 16 is positive silk screw thread b, swivel bolt 1 is anti-silk screw thread a with the screw thread of set screw nut 3, when continuing to be rotatably connected bolt 4, swivel bolt 1 can be along the direction rotation opposite with connecting bolt 4 rotations, after the torque spanner of connecting bolt 4 reaches preset value, swivel bolt 1 stops operating, at this moment, swivel bolt 1 one ends are close on the vehicle body sheet metal 7, the other end still is enclosed within the set screw nut 3, has namely realized making the gap between instrument panel main beam and the body in white to obtain filling.
Present embodiment processing is simple, is convenient to realize, the gap between instrument panel main beam and the body in white has been regulated in the design of the anti-silk structure by swivel bolt and set screw nut, has solved the assemblage gap problem of having brought when instrument panel is installed.
