[0046] As Figures 1 to 11 shown, this application discloses a rivet nut gun, which is characterized in that it includes: a rivet nut gun body 1, a riveting rod 11, a driving component 2, and a receiving component 3;

[0047] Among them, the riveting rod 11, the driving assembly 2 and the receiving assembly 3 are all arranged on the rivet nut gun body 1; the riveting rod 11 has a riveting head 111, and the riveting head 111 has an external thread.

[0048] In addition, the receiving assembly 3 includes: a receiving channel 31, a rivet gun nozzle 32 and an elastic ring 33, and the rivet gun nozzle 32 includes: a sliding cavity 321.

[0049] The receiving channel 31 is connected to the rivet gun nozzle 32, and the receiving channel 31 is adapted to receive and convey the rivet nut 4 to the rivet gun nozzle 32, and the rivet nut 4 has an internal thread.

[0050] The rivet gun nozzle 32 is adapted to hold the rivet nut through the sliding cavity 321 during the upper riveting process and release the rivet nut during the rivet discharging process. The upper riveting process is: the process of rotatably connecting the rivet nut 4 with the riveting head 111 within the rivet gun nozzle 32; the rivet discharging process is: the process of extending the rivet nut 4 connected to the riveting head 111 out of the outlet of the rivet gun nozzle 32.

[0051] Moreover, the driving assembly 2 is adapted to drive the riveting rod 11 to rotate and move the rivet gun nozzle 32 in the first direction to complete the upper riveting process and the rivet discharging process. The first direction is: the direction from the riveting head 111 to the rivet nut gun body 1. Refer to as Figure 1 shown, the x direction is the first direction.

[0052] That is to say, before the rivet nut 4 enters the receiving channel 31, due to the arrangement of the elastic ring 33 on the outer wall of the outlet of the rivet gun nozzle 32, the rivet gun nozzle 32 is in a closed state. After the rivet nut 4 enters the receiving channel 31, the receiving channel 31 is inclined or manually placed in an inclined manner, and the rivet nut 4 slides into the sliding cavity 321 of the rivet gun nozzle 32 under the action of gravity. Since the inner diameter of the inlet of the sliding cavity 321 is larger than the inner diameter of the outlet of the sliding cavity 321, the sliding cavity 321 can accommodate and hold the rivet nut 4. At this time, the driving assembly 2 drives the rivet gun nozzle 32 to move towards the riveting head 111, and the rivet gun nozzle 32 gradually approaches the riveting head 111. When the riveting head enters the rivet gun nozzle 32, the driving assembly 2 drives the riveting rod 11 to rotate, so that the riveting head 111 is rotatably connected with the rivet nut 4. The driving assembly 2 drives the rivet gun nozzle 32 to continue sliding in the first direction, and the riveting head 111 connected to the rivet nut 4 pushes open the riveting nozzle 32 under the action of centripetal force.

[0053] Specifically, as Figure 11As shown, in this embodiment, the riveting gun nozzle 32 further includes an outlet passage 322. The inlet of the sliding cavity 321 is connected to the receiving passage 31, the outlet of the sliding cavity 321 is connected to the inlet of the outlet passage 322, the inner diameter of the inlet of the sliding cavity 321 is larger than the inner diameter of the outlet of the sliding cavity 321, and the sliding cavity 321 has a side wall inclined towards the outlet passage 322.

[0054] As Figure 11 shown, the inner diameter of the inlet of the sliding cavity 321 is larger than that of the outlet and has a side wall inclined towards the outlet passage 322. Specifically, the sliding cavity 321 can be funnel-shaped. This setting of the sliding cavity 321 helps the riveting joint 111 to push open the riveting gun nozzle 32. The riveting joint 111 abuts against the riveting gun nozzle 32. Under the action of centripetal force, the riveting joint 111 exerts a thrust on the riveting nut 4, causing the riveting nut 4 to slide along the sliding cavity 321 towards the outlet passage 322 of the riveting gun nozzle 32, thereby pushing open the riveting gun nozzle 32. That is, at this time, the multiple clamping blocks of the riveting gun nozzle 32 are no longer in a closed state, but there are gaps between the multiple clamping blocks.

[0055] Furthermore, as Figures 4 - 8 shown, in this embodiment, the riveting gun nozzle 32 includes multiple clamping blocks. The multiple clamping blocks are arranged circumferentially along the sliding cavity 321. The first ends (the ends close to the riveting nut gun body 1) of the multiple clamping blocks are connected to the receiving passage 31, and the second ends (the ends far from the nut gun body 1) of the multiple clamping blocks are gathered together by the elastic ring 33. The multiple clamping blocks are connected to the riveting nut gun body 1 through snap rings. The snap ring connection method makes the connection between the multiple clamping blocks more firm and improves the stability of the riveting nut gun during use.

[0056] Furthermore, the riveting gun nozzle 32 can be a three-lobe nozzle structure. The three-lobe nozzle structure means that the riveting gun nozzle 32 is composed of three clamping blocks. The elastic ring 33 is sleeved in the groove on the outer wall of the three-lobe nozzle outlet. The setting of the groove makes the sleeving of the elastic ring 33 more firm and not easy to slip off. Before the driving assembly 2 drives the three-lobe nozzle to slide, the three-lobe nozzle is in a closed state under the restriction of the elastic ring 33. When the riveting nut 4 and the riveting joint 111 continue to slide after being rotationally connected, and with the help of centripetal force and the sliding cavity 321, the three-lobe nozzle is pushed open, that is, at this time, the three-lobe nozzle is in an open state.

[0057] It should be noted that the present application does not limit the specific number of the clamping blocks, and can be reasonably selected and set according to actual needs, as long as it can achieve the purpose that the riveting gun nozzle 32 can be closed and opened and can clamp the riveting nut 4.

[0058] In addition, the circlip pin can be a C-shaped circlip pin, which is composed of a C-shaped spring and a pin. It is easy to install and flexible to use. Due to the structure of the circlip pin, the riveting gun nozzle 32 tends to be in a closed state without being subjected to external force.

[0059] Further, the elastic ring can be a silicone rubber ring with an outer diameter of 17 mm, a wire diameter of 3.5 mm, a hardness of 50-55 IRHD, and a temperature resistance of -50-180 degrees.

[0060] In addition, the driving assembly 2 is further adapted to drive the riveting rod 11 to rotate and move along the first direction after the riveting process is completed, so that the riveting nut is riveted to the mounting hole.

[0061] That is to say, after the riveting process is completed, at this time, the riveting head 111 and the riveting nut 4 are in a rotational connection state, and the riveting gun nozzle 32 is in an open state. Align the riveting nut gun with the mounting hole, and the driving assembly 2 drives the riveting rod to rotate and move along the first direction, and the riveting nut deforms to complete the riveting with the mounting hole.

[0062] Further, as Figures 3 - 6 shown, the driving assembly 2 includes a driving member 21 and a sliding mechanism 22.

[0063] The driving member 21 is used to drive the riveting rod 11 to rotate and move the receiving assembly 3 on the sliding mechanism 22.

[0064] In addition, the sliding mechanism 22 includes a slide rail 221 and a sliding member 222. The slide rail 221 is arranged on the riveting nut gun body 1, the sliding member 222 is slidably arranged on the slide rail 221, the slide rail extends along the first direction, and the receiving assembly 3 is arranged on the sliding member 222. The sliding mechanism 22 is connected to the riveting nut gun body 1 through a pin structure 23.

[0065] By driving the driving member 21 to drive the sliding member 222 to move on the slide rail 221, the riveting gun nozzle 32 is driven to move on the slide rail 221. Between the driving assembly 2 and the sliding mechanism 22, and between the sliding mechanism 22 and the riveting nut gun body 1, they can all be connected through the pin structure 23, and the pin structure 23 makes it convenient to separate and replace the structures.

[0066] Further, in another embodiment of the present application, the nut gun further includes a monitoring mechanism and a control system. The monitoring mechanism is adapted to detect the riveting nut 4 in the riveting gun nozzle 32; the control system is adapted to start the riveting process when the monitoring mechanism monitors the riveting nut 4.

[0067] Generally speaking, the present application provides a blind rivet nut gun. Before the blind rivet nut 4 enters the receiving channel 31, due to the arrangement of the elastic ring 33 on the outer wall of the outlet of the rivet gun nozzle 32 and the connection mode of the clamping block of the rivet gun nozzle 32 and the blind rivet nut gun body by the circlip pin, the rivet gun nozzle 32 is in a closed state. After the blind rivet nut 4 enters the receiving channel 31, the receiving channel 31 is inclined or manually placed in an inclined manner, and the blind rivet nut 4 slides into the sliding cavity 321 of the rivet gun nozzle 32 under the action of gravity. Since the inner diameter of the inlet of the sliding cavity 321 is larger than the inner diameter of the outlet of the sliding cavity 321, the sliding cavity 321 can accommodate and retain the blind rivet nut 4. At this time, the driving assembly 2 drives the rivet gun nozzle 32 to move towards the riveting joint 111, gradually approaching the riveting joint 111. When the riveting joint enters the rivet gun nozzle 32, the driving assembly 2 drives the riveting rod 11 to rotate, so that the riveting joint 111 is rotationally connected to the blind rivet nut 4. The driving assembly 2 drives the rivet gun nozzle 32 to continue sliding in the first direction, and the riveting joint 111 connected to the blind rivet nut 4 pushes open the riveting nozzle 32 under the action of centripetal force. At this time, the blind rivet nut gun is aligned with the mounting hole, and the driving assembly 2 drives the riveting rod 11 to rotate and move in the first direction, and the blind rivet nut 4 deforms to complete the riveting with the mounting hole.

[0068] This process does not require manual screwing of the blind rivet nut into the blind rivet nut gun, and can realize the rotational connection between the blind rivet nut and the riveting joint and subsequent automatic riveting actions, improving the riveting efficiency.

[0069] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
