BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is an overall schematic diagram of the floating telescopic guiding device for the head of this riveting gun. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following are specific embodiments of the present invention in combination with the drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0014] In the figure, riveting gun 1; housing 2; rivet rod connecting seat 3; rotating seat 4; rivet rod 5; rivet nut 6; rivet rod connecting pin 7; clearance hole 8; floating adjustment space 9; vertical holding fit structure 10; mating port 11; flange member 12; floating sleeve 13; floating seat 14; nut 15; rivet rod connecting member 16; inclined mating port 17; rubber elastic element 18; upper moving interval 19; lower moving interval 20; spherical washer 21; washer sliding seat 22.

[0015] As Figure 1 shown, the floating telescopic guiding device for the head of this riveting gun is arranged at the lower part of the riveting gun 1, wherein the riveting gun 1 has a housing 2, including a rivet rod connecting seat 3, a rotating seat 4, a rivet rod 5 and a rivet nut 6. A rivet rod connecting pin 7 is also arranged on the riveting gun 1 for connecting with the lower rivet rod connecting seat 3. The rotating seat 4 is provided with a clearance hole 8, and the rivet rod connecting seat 3 is sleeved in the clearance hole 8 and the two are in shaft fit with the clearance hole 8, so that the rivet rod 5 and the rotating seat 4 are always coaxial and the cross section of the rivet rod 5 and the rotating seat 4 is always perpendicular.

[0016] This patent has two main innovative aspects. First, the upper end of the riveting rod 5 is connected to the riveting rod connecting seat 3. Here, the riveting rod 5 and the riveting rod connecting seat 3 are detachably connected by threads. The lower end of the riveting rod 5 has a riveting nut 6. The riveting rod 5 is coaxial with the rotating seat 4. The lower end of the rotating seat 4 has a vertical holding and mating structure 10 that mates with the upper end of the riveting nut 6. Here, the vertical holding and mating structure 10 includes a mating opening 11 formed at the lower end of the rotating seat 4. The upper end of the riveting nut 6 has a flange member 12. The mating opening 11 mates with the flange surface and the circumferential surface of the flange member 12 and bears axial and radial support forces during riveting. Since the riveting rod connecting seat 3 is sleeved in the clearance hole 8 and the two have an axial fit in the clearance hole 8, the riveting rod connecting seat 3 and the rotating seat 4 can be adjusted along the clearance to a certain extent. Additionally, the mating of the mating opening 11 and the flange member 12 is mainly used to achieve the effect of correcting the radial deviation and poor perpendicularity of the threaded section of the riveting nut 6 caused by the unbalanced axial force distributed circumferentially in the deformation area of the riveting nut 6 during the riveting process of the riveting rod 5.

[0017] Another innovation of this patent is that a floating telescopic structure is also provided on the rotating seat 4 and the riveting rod connecting seat 3 to ensure the follow-up deflection of the rotating seat 4 and the riveting rod connecting seat 3. Here, the floating telescopic structure includes a floating sleeve 13, a floating seat 14, and a nut 15. The upper end of the riveting rod connecting seat 3 has a riveting rod connecting member 16. The floating sleeve 13 is sleeved on the outer end of the rotating seat 4 between the nut 15 and the riveting rod connecting member 16. The riveting gun 1 has a housing 2. The floating seat 14 is located in the housing 2 and supports the floating sleeve 13 inwardly. Here, the riveting gun 1 is connected to the riveting rod through the riveting rod connecting seat 3 and drives the rotating seat 4 to move through the riveting rod connecting seat 3. Also, since the floating sleeve 13 is at the outer end of the rotating seat 4, the floating sleeve 13 will also move. The floating seat 14 can support the stable movement of the floating sleeve 13. There is a floating adjustment space 9 between the housing 2, the floating sleeve 13, and the riveting rod connecting member 16. There is an inclined mating opening 17 between the floating sleeve 13 and the riveting rod connecting seat 3, which facilitates the floating movement of the entire floating sleeve 13. To prevent the floating sleeve 13 from contacting the housing 2 of the riveting gun 1 when moving, there is a rubber elastic element 18 between the floating sleeve 13 and the housing 2. To limit the floating position of the lower part of the floating sleeve 13, there is an upper moving interval 19 between the upper end of the floating sleeve 13 and the riveting rod connecting member 16, and a lower moving interval 20 between the lower end of the riveting rod connecting seat 3 and the rotating seat 4. The lower end of the floating seat 14 is provided with a spherical washer 21, and a washer sliding seat 22 is provided between the spherical washer 21 and the nut 15. Here, by using the washer sliding seat 22 to abut against the nut 15, it can ensure that the floating sleeve 13 moves to the lower limit position. Here, through the floating telescopic structure of the rotating seat 4 in this patent, the rotating seat 4 and the riveting rod connecting seat 3 follow-up deflect, the riveting rod is only subjected to axial force, and the pulling force of the riveting rod on the riveting nut 6 is always perpendicular to the flange surface of the nut, achieving the effect of avoiding the fracture of the riveting rod when the axis of the riveting gun 1 is not perpendicular to the riveting hole during the riveting process.

[0018] The specific embodiments described herein are merely illustrative of the spirit of the present invention, and those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the scope defined by the spirit of the present invention.
