DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention.

Therefore, an object defined as "first," "second," etc. may explicitly or implicitly include one or more of such objects. Furthermore, "a," "an," and similar terms do not imply a limitation on quantity, but rather indicate the presence of at least one, and "plurality" means at least two.

[0029] In the description of this utility model specification, reference to "one embodiment" or "some embodiments" means that one or more embodiments of the utility model include a particular feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments", unless otherwise specifically emphasized.

[0030] According to the first aspect of the present invention, a rivet gun integral module is provided, which is easy to assemble. Figures 1 to 4 In some embodiments, the integrated module includes a first housing 10 , a second housing 20 , a motor 30 , a first gear 40 , a gear shaft 50 , a gear nut 60 and a screw 70 .

[0031] The first housing 10 is made of metal, such as stainless steel or aluminum alloy. A chamber 11 is provided within the first housing 10. A discharge port 12 is provided on one end of the chamber 11. At the other end of the chamber 11, the first housing 10 is connected to a second housing 20, which can be made of metal or plastic. A first mounting cavity 13 and a second mounting cavity 14 are provided on the side of the discharge port 12. The second mounting cavity 14 is located between the first mounting cavity 13 and the discharge port 12.

[0032] The motor 30 is disposed at a side of the first installation cavity 13 . The first gear 40 is rotatably disposed in the first installation cavity 13 . The first gear 40 is connected to an output shaft of the motor 30 .

[0033] A second gear 51 is provided at one end of the gear shaft 50 , and a spline 52 is provided at the other end. The second gear 51 is rotatably disposed in the second mounting cavity 14 , and the second gear 51 is meshed with the first gear 40 .

[0034] The gear nut 60 is rotatably disposed in the second housing 20 , and the gear nut 60 is engaged with the spline 52 .

[0035] The screw rod 70 is disposed within the gear nut 60 and is threadedly engaged with the gear nut 60. Specifically, the outer wall of the screw rod 70 is provided with a thread, and the inner wall of the gear nut 60 is provided with a mating thread structure. The screw rod 70 is provided with a discharge pipe 71 inside, and the discharge pipe 71 is coaxially arranged with the discharge port 12.

[0036] Reference Figure 2 The central axis of the motor 30, the central axis of the gear shaft 50, and the central axis of the screw rod 70 are parallel, and the gear shaft 50 is located between the motor 30 and the screw rod 70. Such an arrangement can improve the integration of the integral module and reduce its occupied space.

[0037] During application, the motor 30 can drive the first gear 40 to rotate when working. The first gear 40 drives the gear shaft 50 to rotate by engaging with the second gear 51. Then the spline 52 on the gear shaft 50 drives the gear nut 60 to rotate. The gear nut 60 then drives the screw rod 70 along its axial direction through its matching structure with the screw rod 70, thereby realizing functions such as riveting. The discharge pipe 71 can be used to discharge the top core after riveting.

[0038] The integral module of the rivet gun of the present invention adopts a modular design with high integration, convenient assembly, and improved assembly efficiency; since the first shell 10 is made of metal, and structures such as gears are assembled in the corresponding cavity of the first shell 10, the overall structural strength and installation accuracy of the integral module can be guaranteed, and the shaking of the integral module during use can be avoided, thereby improving the reliability of the rivet gun and extending the service life of the rivet gun.

[0039] In some preferred embodiments, the integrated module further includes a movable block 80, which is movably disposed within the accommodating cavity 11. The screw rod 70 is disposed within the movable block 80 and is threadedly engaged with the movable block 80. Specifically, the outer wall of the screw rod 70 is provided with a thread, and the inner wall of the movable block 80 is provided with a threaded structure that cooperates with the threaded structure.

[0040] Further, refer to Figure 3 and Figure 4 Fixed seats 15 are provided on the upper and lower sides of the first housing 10. Slide slots 151 are provided on the fixed seats 15 (on the side facing the movable block 80). The slide slots 151 extend parallel to the central axis of the screw rod 70. Limiting posts 81 are provided on the upper and lower sides of the movable block 80, and are movably disposed within the corresponding slide slots 151. When the gear nut 60 drives the screw rod 70 to move along its axial direction, the movable block 80 also drives the movable block 80 along this axial direction due to the mating structure between the movable block 80 and the screw rod 70. This causes the limiting posts 81 to move along the corresponding slide slots 151, ensuring the linearity and reliability of the axial movement of the screw rod 70.

[0041] Furthermore, a limiting flange 72 is provided at each end of the screw rod 70, and the outer diameter of the limiting flange 72 is larger than the inner diameter of the moving block 80 and the inner diameter of the gear nut 60, thereby preventing the moving block 80 from falling off the screw rod 70 and ensuring the reliability of the integrated module.

[0042] Reference Figure 1 In some preferred embodiments, the first housing 10 includes a detachably connected upper housing 16 and a lower housing 17. The upper housing 16 and the lower housing 17 are each formed of an integral metal structure, ensuring high structural strength. The upper housing 16 and the lower housing 17 can be detachably connected using conventional methods such as screws or snap connections. For example, in some embodiments, the upper housing 16 and the lower housing 17 are detachably connected using screws 18.

[0043] Reference Figure 2In some preferred embodiments, the second housing 20 is provided with an opening 21 corresponding to the spline 52, and a portion of the gear nut 60 is exposed through the opening 21 to engage with the spline 52. Furthermore, the number of openings 21 is not limited to one. For example, the second housing 20 may be provided with multiple openings 21 around the circumference of the gear nut 60 to expose multiple areas of the gear nut 60.

[0044] Reference Figure 1 or Figure 2 In some preferred embodiments, a reducer 31 is further provided between the motor 30 and the first gear 40. The output shaft of the motor 30 is connected to the input end of the reducer 31, and the output end of the reducer 31 is connected to the first gear 40. The reducer 31 can be a conventional gear reducer or the like. Its structure and operating principle are conventional and will not be described in detail here.

[0045] According to the second aspect of the present invention, a rivet gun is provided, which includes the above-mentioned integrated module. When the above-mentioned integrated module is applied to the rivet gun, the motor 30 can drive the first gear 40 to rotate when working. The first gear 40 drives the gear shaft 50 to rotate by engaging with the second gear 51. Then the spline 52 on the gear shaft 50 drives the gear nut 60 to rotate. The gear nut 60 then drives the screw rod 70 along its axial movement through its matching structure with the screw rod 70, thereby realizing functions such as riveting. The discharge pipe 71 can be used for discharging the top core after riveting. Since the first shell 10 is made of metal material and the gears and other structures are assembled in the corresponding cavity of the first shell 10, the overall structural strength and installation accuracy of the integrated module can be guaranteed, and the shaking of the integrated module during use can be avoided, thereby improving the reliability of the rivet gun and extending the service life of the rivet gun.

[0046] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
