It can rivet rivet products that do not require tapping internal threads or welding nuts. It has high riveting efficiency and is convenient and quick to use.

[0003] In the use of existing rivet guns, a threaded rod is usually used to connect the rivet nut. A rivet hole is pre-processed on the plate to be connected, and the threaded rod is inserted into the rivet hole. One end of the threaded rod is connected to the rivet gun, and the other end is threadedly connected to the rivet nut. The threaded rod is pulled by the rivet gun to make the flower teeth of the rivet nut squeeze into the plate to achieve the riveting of the rivet nut and the plate. However, when using the rivet gun for rivet, the rivet gun needs to abut against the workpiece and pull the threaded rod. Due to the large rivet force, the workpiece is prone to indentation or even deformation, which affects the yield rate of the workpiece.

[0004] Therefore, there is an urgent need for a rivet gun protective device and a rivet gun assembly to solve the above problems. Summary of the invention

[0030] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figure 1 and Figure 2 As shown, the rivet gun protection device of this embodiment includes a protection member 100, which abuts between the workpiece to be riveted and the rivet gun. The protection member 100 includes an abutment surface 110, which is set as an arc surface. The abutment surface 110 abuts against the workpiece, and the shape of the abutment surface 110 matches the shape of the workpiece.

[0032] Based on the above design, the protective member 100 abuts between the workpiece to be riveted and the rivet gun, which can prevent the rivet gun from directly applying pressure to the workpiece and reduce the wear and scratches of the workpiece by the rivet gun. The abutting surface 110 is set as an arc surface, and the curved shape of the arc surface matches the shape of the workpiece, which can provide good support for the workpiece and expand the actual contact area between the protective member 100 and the workpiece, which is conducive to dispersing the pressure on the workpiece, reducing the pressure on the contact surface of the workpiece during riveting, thereby reducing the probability of compression deformation of the workpiece and ensuring the good quality rate of the workpiece.

[0033] Specifically, the protective member 100 is provided with a through hole 120, which passes through the workpiece and the rivet gun. The threaded rod can be passed through the through hole 120 and the rivet hole on the workpiece, and one end of the threaded rod is connected to the rivet gun, and the other end is threadedly connected to the rivet nut to be riveted. The rivet gun pulls the threaded rod, thereby driving the rivet nut to rivet with the workpiece.

[0034] Preferably, the protective member 100 can be set as a plastic member. Plastic members are low in cost and easy to manufacture, which is conducive to reducing production costs. In addition, the plastic member is light in weight, which facilitates the movement of the protective member 100 when riveting different riveting holes on the workpiece, thereby reducing the labor of workers. In addition, when the workpiece is a metal plate, the hardness of the plastic member is less than that of the workpiece. When the protective member 100 abuts against the workpiece, it can avoid scratching the workpiece by the protective member 100, further ensuring the surface quality of the workpiece. Optionally, the protective member can be made of PA6 nylon plastic, PA56 nylon plastic, PBT engineering plastic, etc.

[0035] In this embodiment, the protective member 100 is configured as a square block structure. In some other embodiments, the protective member 100 can also be configured as a cylindrical, trapezoidal table structure, etc., which has a simple structure and is easy to produce.

[0036] Furthermore, the rivet gun protective device further includes an isolation pad 200, which is connected to a side of the protective member 100 facing the rivet gun, and the rivet gun abuts against the isolation pad 200. By providing the isolation pad 200, the rivet gun directly contacts the isolation pad 200, and the hardness of the isolation pad 200 is greater than that of the protective member 100, and has good impact resistance, which is beneficial to improving the service life of the rivet gun protective device, reducing the replacement frequency, and reducing the use cost.

[0037] Optionally, the isolation pad 200 is configured as a metal gasket, such as a stainless steel gasket, an aluminum alloy gasket, etc., which is easy to manufacture or purchase. The isolation pad 200 can also be configured as an annular gasket, and the threaded rod can be inserted into the isolation pad 200 to ensure that the threaded rod can be evenly stressed in the circumferential direction.

[0038] Furthermore, a mounting groove 130 is provided on the side of the protective member 100 facing the rivet gun, and the isolation pad 200 is installed in the mounting groove 130 , so as to facilitate the positioning and installation of the isolation pad 200 .

[0039] In this embodiment, the isolation pad 200 is also provided with a plurality of connection holes, which are evenly distributed on the isolation pad 200, and a plurality of screws are passed through the plurality of connection holes and connected to the protective member 100, so as to ensure a stable connection between the isolation pad 200 and the protective member 100. In some other embodiments, the isolation pad 200 and the protective member 100 may also be connected by bonding, clamping, etc., which will not be described in detail here.

[0040] This embodiment also provides a rivet gun assembly including a rivet gun, a connecting device and the above-mentioned rivet gun protective device, wherein the connecting device is inserted into the rivet gun protective device, one end of the connecting device is connected to the rivet gun, and the other end presses the workpiece against the abutment surface 110. The rivet gun assembly can avoid direct contact between the rivet gun and the workpiece when riveting the rivet nut and the workpiece, reduce the deformation of the workpiece, and improve the yield rate of the workpiece.

[0041] Specifically, the connecting device includes a connecting rod and a connecting bolt. A first threaded hole is arranged at one end of the connecting rod close to the workpiece. The connecting bolt is passed through the rivet nut to be riveted and is threadedly connected with the first threaded hole. Compared with the prior art of directly connecting the rivet nut with a threaded rod, such a setting can increase the length of the threaded part of the threaded connection structure that bears pressure, improve the service life of the threaded connection structure, and save production costs.

[0042] In some embodiments, the connecting rod is threadedly connected to the rivet gun. The connecting rod can be threadedly connected to the rivet gun by setting a threaded rod or a second threaded hole, which has a simple structure and is easy to install. In some other embodiments, the connecting rod can also be connected to the rivet gun by plugging, pinning, etc., which will not be repeated here.

[0043] Optionally, the connecting rod further includes a protrusion, which protrudes outward in the radial direction of the connecting rod, and the protrusion is confined in the rivet gun to facilitate the installation and positioning of the connecting rod.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
