Description

  The present invention relates to a floating nut assembly that is attached by adjusting the position of the attached component when the attached component is attached to the instrument body.

When attaching a part to be attached to a device body such as a panel using a bolt, a holding structure using a movable nut is employed to compensate for manufacturing errors of each component.
A screw hole through which a bolt loosely penetrates is formed in both the device main body and the mounted part, and the mounted part is attached to the apparatus main body using a bolt and a nut.
At this time, if a movable nut is mounted on the back side of the device body so that it can move by a desired amount, it is easy to turn the bolt outside the device body without turning the hand and turning the back side of the device body. A part to be attached can be attached to the device body.
When a part such as a door hinge of an automobile is attached to a body panel or the like, it is difficult to turn a hand to the back surface of the body panel. Therefore, the attached part is attached to the body panel by this movable nut structure.

FIG. 1 is an exploded perspective view of a conventional movable nut (floating nut) structure before mounting a component, and FIG. 2 is a cross-sectional view after mounting the component.
This structure includes a body panel 2, a nut plate 3, and a bracket 4, and a mounted component 5 is fixed to the nut plate 3 with a mounting bolt 6. The body panel 2 has a pair of through holes 2a having an inner diameter slightly larger than the outer diameter of the mounting bolt 6. The attached component 5 has a pair of through holes 5a through which the attachment bolts 6 are inserted. The nut plate 3 is formed with a pair of mounting holes 3a in which a female screw for fixing the mounting bolt 6 is cut. The bracket 4 is sized to accommodate the nut plate 3 and has a pair of through holes 4a having an inner diameter slightly larger than the outer diameter of the mounting bolt 6.

When attaching the part 5 to the body panel (device main body) 2, the nut plate 3 is placed on the body panel 2, the bracket 4 is placed thereon, and the end of the bracket 4 is welded to the body panel 2. Alternatively, the bracket 4 can be fixed to the body panel 2 by screwing or the like instead of welding. In this state, the nut plate 3 can move to some extent within the bracket 4, but cannot be rotated because it is surrounded by the bracket 4. The mounting bolt 6 is inserted through the through hole 5a of the mounted part 5 and the through hole 2a of the body panel 2, and the mounting bolt 6 is bolted to the mounting hole 3a of the nut plate 3. Since the nut plate 3 is slidable to some extent along the back surface of the body panel 2 within the bracket 4, the position of the tip of the mounting bolt 6 can be bolted by matching the mounting hole 3a of the nut plate 3. The tip of the mounting bolt 6 slightly protrudes from the hole 4a of the bracket 4.
In this structure, in order to hold the nut plate 3 movably, a bracket 4 that covers the nut plate 3 is necessary, and the bracket 4 must be fixed to the body panel 2 by welding or the like. Further, a space for accommodating the nut plate 3 and the bracket 4 is required on the back side of the body panel 2.

The plate-like nut 20 further has a pair of screw holes 22 outside the pair of through holes 21. The inner diameter 22d of the screw hole 22 matches the screw of the outer diameter 52d of the bolt 50, and is used to bolt the mounted part 40 with the bolt 50.

FIG. 6C is a cross-sectional view of the pin receiving plate member 30. The pin receiving plate member 30 has a pair of fixing holes 31 at positions corresponding to the pair of through holes 21 of the plate-like nut 20. The inner diameter 31d of the fixing hole 31 is smaller than the inner diameter 21d of the pair of through holes 21 of the plate nut 20. The inner diameter 31d of the fixing hole 31 is larger than the outer diameter 15d of the distal end portion 15 of the fixing portion 13 of the press pin 10 and smaller than the outer diameter 12d of the shaft portion 12.
When the shaft portion 12 of the press pin 10 is pushed into the fixing hole 31 of the pin receiving plate material 30, the material around the fixing hole 31 of the pin receiving plate material 30 flows through the metal, and the press pin 10 is fixed to the pin receiving plate material 30. It has become so.

The fixing hole 31 of the pin receiving plate material 30 is a hole having the same diameter from the upper surface to the lower surface of the pin receiving plate material 30. Since the pin receiving plate member 30 is, for example, a body panel for an automobile, a hole having a simple shape is preferable for easy processing.
Even when the fixing portion 13 ′ of the press pin 10 has the shape shown in FIG. 5B, the inner diameter 31 d of the fixing hole 31 of the pin receiving plate member 30 is larger than the outer diameter 15 d ′ of the tip portion 15 ′ of the press pin 10.

The pin receiving plate member 30 has through holes 32 at positions corresponding to the pair of screw holes 22 of the plate-like nut 20. The inner diameter 32d of the through hole 32 is slightly larger than the outer diameter 52d of the shaft portion 52 of the bolt 50, so that the shaft portion 52 of the bolt 50 can be inserted.
The pin receiving plate material 30 is made of a material softer than the press pin so that the metal flows when the press pin 10 is press-fitted. For example, a mild steel plate such as SPCC, a galvanized mild steel plate, an A5000 series aluminum plate, and an A6000 series aluminum plate.

FIG. 7 shows a state in which the shaft portion 12 of the press pin 10 is inserted into the pair of through holes 21 of the plate-like nut 20 and the shaft portion 12 of the press pin 10 is press-fitted into the fixing hole 31 of the pin receiving plate material 30 and fixed. Show. That is, the floating nut assembly 1 is assembled.
The operation of bolting the mounted member 40 to the plate-like nut 20 with the bolt 50 has not been performed yet.
An inner diameter 42d of the through hole 42 of the mounted member 40 is larger than an outer diameter 52d of the shaft portion 52 of the bolt 50, and the shaft portion 52 of the bolt 50 can be inserted therethrough.

FIG. 8 shows that the material of the pin receiving plate material 30 is made to flow through the metal portion of one press pin 10 indicated by B in the floating nut assembly 1 in FIG. 7 and the shaft portion 12 of the press pin 10 is fixed to the pin receiving plate material 30. It is an expanded sectional view which shows the process to do. FIG. 8A shows a stage before the press pin 10 is inserted into the plate-like nut 20 and the pin receiving plate member 30. The outer diameter 12 d of the shaft portion 12 of the press pin 10 is larger than the inner diameter 31 d of the fixing hole 31 of the pin receiving plate material 30. The outer diameter 14 d of the intermediate portion 14 of the press pin 10 and the outer diameter 15 d of the tip portion 15 are smaller than the inner diameter 31 d of the fixing hole 31. That is, the relationship between the dimensions of each part is as follows.
The outer diameter 14d of the intermediate part 14 <the outer diameter 15d of the tip part 15 <the inner diameter 31d of the fixing hole 31 <the outer diameter 12d of the shaft part 12

FIG. 8B shows a state before the shaft portion 12 of the press pin 10 is inserted into the through hole 21 of the plate nut 20 and press-fitted. When the press pin 10 is inserted into the fixing hole 31 from the tip portion 15, the tip portion 15 and the intermediate portion 14 enter the fixing hole 31, and the tip portion of the shaft portion 12 comes into contact with the pin receiving plate material 30 and stops. .
FIG. 8C shows a state where the shaft portion 12 of the press pin 10 is press-fitted into the fixing hole 31 of the pin receiving plate member 30 (state of FIG. 7). The press-fitting can be performed by driving with a press machine. At this time, the material around the fixing hole 31 of the pin receiving plate member 30 is pushed by the tip of the shaft portion 12 to flow through the metal, and enters the intermediate portion 14 where the diameter of the press pin 10 is small. Therefore, the tip 15 of the press pin 10 cannot be removed, and the press pin 10 is fixed to the pin receiving plate material 30.

In this state, the plate nut 20 is located between the flange 11 of the press pin 10 and the pin receiving plate member 30. Since the inner diameter 21d of the through hole 21 of the plate-shaped nut 20 is larger than the outer diameter 12d of the shaft portion 12 of the press pin 10, the plate-shaped nut 20 has a clearance (the inner diameter 21d of the through-hole 21 and the outer diameter 12d of the shaft portion 12). It is possible to slide by the difference.
The length 12L of the shaft portion 12 of the press pin 10 is larger than the thickness 20t of the plate nut 20, so that the press pin 10 is not fixed to the plate nut 20 when the press pin 10 is pushed into the pin receiving plate material 30. It has become.
In FIG. 8, the fixing portion 13 of the press pin 10 has the shape shown in FIG. 5 (a), but the material of the pin receiving plate material 30 is also formed in the V-shaped groove in the case of FIG. 5 (b). Metal press can be used to fix the press pin 10.

  FIG. 9 shows a floating nut assembly in which the press pin 10 of FIG. 7 is fixed to the pin receiving plate material 30 and the plate nut 20 is slidably held by the clearance, and the shaft portion 52 of the bolt 50 is further attached. 3 is a cross-sectional view showing a state in which the through hole 42 of the member 40 and the through hole 32 of the pin receiving plate member 30 are passed through and fixed to the screw hole 22 of the plate-like nut 20. FIG. Since the plate-like nut 20 can slide to some extent on the pin receiving plate member 30, the bolt 50 can be bolted by adjusting the tip of the bolt 50 to the position of the screw hole 22 of the plate-like nut 20. When the bolt 50 is bolted to the plate nut 20, the plate nut 20 is not slidable.

According to the embodiment of the present invention, since a plate-shaped nut having a simple shape in which a pin is driven and stopped so as to be movable is used, the fixing structure can be reduced in weight and simplified.
Further, since the cover for covering the nut is eliminated and the operation of welding the cover is eliminated, the process is simple and the cost can be reduced.
