Abstract
The utility model discloses an automobile steel plate connecting structure which comprises a first steel plate, a second steel plate, a connecting bolt and a nut seat, wherein the nut seat is provided with a threaded hole; the nut seat is positioned in the nut seat assembly hole and is in clearance fit with the nut seat assembly hole, and the rod part of the connecting bolt penetrates through the first connecting round hole and the second connecting round hole and extends into the threaded hole to be in threaded connection with the nut seat, so that the first steel plate and the second steel plate are fixedly connected together. The utility model can avoid affecting the performance of the steel plate.
Description
Technical Field
The utility model belongs to the field of automobile parts, and particularly relates to an automobile steel plate connecting structure.
Background
As shown in fig. 1, the existing automobile steel plate connecting structure comprises a first steel plate 1, a second steel plate 2, a projection welding bolt 5 and a locking nut 6, wherein the projection welding bolt 5 penetrates through the second steel plate 2 and is vertically welded on the second steel plate 2, a connecting hole is formed in the first steel plate 1, and the projection welding bolt 5 penetrates through the connecting hole and is in threaded connection with the locking nut 6, so that the first steel plate 1 is fixedly connected with the second steel plate 2. This kind of connection structure, when welding projection welding bolt 5, need make the frock, guarantee projection welding bolt 5 and the straightness that hangs down on second steel sheet 2 surface, increased the technology degree of difficulty to cause the second steel sheet part to receive the welding slag to destroy when welding projection welding bolt 5 on second steel sheet 2 easily, influence second steel sheet local strength, thereby arouse the second steel sheet performance decline.
Disclosure of Invention
The utility model aims to provide an automobile steel plate connecting structure to avoid influencing the performance of a steel plate.
The automobile steel plate connecting structure comprises a first steel plate, a second steel plate, a connecting bolt and a nut seat, wherein a threaded hole is formed in the nut seat, a first connecting round hole is formed in the first steel plate, a second connecting round hole corresponding to the first connecting round hole is formed in one side of the second steel plate, a nut seat assembling hole is formed in the other side of the second steel plate, and the nut seat assembling hole is axially communicated with the second connecting round hole; the nut seat is positioned in the nut seat assembly hole and is in clearance fit with the nut seat assembly hole, and the rod part of the connecting bolt penetrates through the first connecting round hole and the second connecting round hole and extends into the threaded hole to be in threaded connection with the nut seat, so that the first steel plate and the second steel plate are fixedly connected together.
Preferably, the nut seat is square, the nut seat assembling hole is a square hole, and the length and the width of the nut seat are both larger than the diameter of the second connecting round hole. The length and the width of the corresponding nut seat assembling hole are both larger than the diameter of the second connecting round hole. The nut seat is square, and the nut seat assembly hole is the square hole, can guarantee that processing is convenient, also can avoid connecting bolt nut seat to rotate when screwing up.
The first steel plate and the second steel plate are fixedly connected together by utilizing the nut seat and the connecting bolt, so that the connection is firm, no welding process is required, a welding tool is cancelled, the possibility of damaging the second steel plate is reduced, the performance of the second steel plate is prevented from being influenced, and the problem that the strength of the second steel plate is influenced due to local damage is solved.

Detailed Description
As shown in fig. 2 to 6, the steel plate connecting structure for an automobile in the present embodiment includes a first steel plate 1, a second steel plate 2, a connecting bolt 3, and a nut holder 4. The nut seat 4 is square, a threaded hole 41 is formed in the nut seat 4, a first connecting circular hole 11 is formed in the first steel plate 1, the diameter of the first connecting circular hole 11 is slightly larger than the diameter of the thread of the connecting bolt 3, and the rod portion of the connecting bolt 3 can be ensured to pass through the first connecting circular hole 11. The second connecting round hole 21 corresponding to the first connecting round hole 11 is formed in one side of the second steel plate 2, the diameter of the second connecting round hole 21 is larger than that of the thread of the connecting bolt 3, it is guaranteed that the rod portion of the connecting bolt 3 can pass through the second connecting round hole 21, and the length and the width of the nut seat 4 are larger than those of the second connecting round hole 21. Nut seat pilot hole 22 has been seted up to the opposite side of second steel sheet 2, and nut seat pilot hole 22 is the square hole, and nut seat pilot hole 22 is connected round hole 21 axial intercommunication with the second, and the length of nut seat pilot hole 22, width all are greater than the diameter that round hole 21 is connected to the second. The connecting bolt 3 is a standard structural member without special requirements, the length and the thread specification of the connecting bolt 3 are determined according to the strength, the thickness and the like of the first steel plate 1 and the second steel plate 2, and the specification and the model are selected to be matched with the threaded hole 41 on the nut seat 4.
During assembly, the nut seat 4 is placed in the nut seat assembly hole 22, and the nut seat 4 is in clearance fit with the nut seat assembly hole 22; then the end surface of the nut seat 4 is abutted against the bottom surface of the nut seat assembly hole 22, the rod part of the connecting bolt 3 penetrates through the first connecting round hole 11 and the second connecting round hole 21 and extends into the threaded hole 41 to be screwed tightly, and the connecting bolt 3 is screwed with the nut seat 4, so that the first steel plate 1 and the second steel plate 2 are fixedly connected together. After the assembly, the end surface of the nut seat 4 is tightly attached to the bottom surface of the nut seat assembly hole 22, and the head end surface of the connecting bolt 3 is tightly attached to the first steel plate 1.
