[0002] A nut riveting machine is a riveting device specifically used for pressing nuts. Different from traditional riveting machines, it can directly press nuts into workpieces and cooperate with threads to form a connection with a certain strength. A nut riveting machine usually consists of a body and a riveting tool. The body is usually driven by an electric motor or a hydraulic system to provide sufficient pressure to complete the process of pressing nuts. The riveting tool is a specially designed tool for pressing nuts into workpieces and making them fit tightly with the threads.

[0003] The inventor believes that in the related art, for the support tube that supports the nut on the nut riveting machine, most of them are assembled at the processing part of the riveting machine through a threaded structure. However, the inner diameter of the threaded hole opened on the riveting machine for assembling the support tube is determined, which leads to a limited number of replaceable models of the support tube. Based on the above problems, a nut riveting device is provided.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

A bidirectional threaded rod is rotatably connected inside the chute, and one end of the bidirectional threaded rod is arranged outside the riveting machine body. A pair of sliders are threadedly connected to the middle of the bidirectional threaded rod. The tops of the two sliders are fixedly connected with clamping blocks. Both clamping blocks are arranged in the groove. A support tube for receiving nuts is placed inside the groove, and the outer surfaces of the two clamping blocks are in pressing contact with the support tube.

[0008] By adopting the above technical solutions, it is convenient for operators to replace support tubes of different sizes and models, and to a certain extent, it can meet the riveting operations of different nuts for different workpieces.

[0009] Preferably, the shape of the chute is convex, and the slider is fully adapted to the chute.

[0010] By adopting the above technical solution, the stable sliding of the slider in the chute can be ensured, and the situation of the slider shifting and loosening can be avoided.

[0011] Preferably, the opposite side surfaces of the two clamping blocks are both concave arc-shaped.

[0012] By adopting the above technical solution, the area of contact between the two clamping blocks and the support pipe can be increased, thereby increasing the stability of the assembly of the support pipe.

[0013] Preferably, rubber gaskets are bonded to the opposite side surfaces of the two clamping blocks.

[0014] By adopting the above technical solution, the outer side surface of the support pipe can be contacted by the rubber gasket, thereby increasing the stability of the assembly of the support pipe in the groove.

[0015] Preferably, a T-shaped support pad is slidably assembled on the processing table of the riveting machine body.

[0016] By adopting the above technical solution, for workpieces with a larger area, the T-shaped support pad can be slid so that the top of the T-shaped support pad contacts the bottom of the workpiece, thereby increasing the horizontality of the workpiece placement and ensuring the riveting between the nut and the workpiece.

[0017] In summary, the present application includes the following beneficial technical effects:

[0018] Through rotating the bidirectional threaded rod, the two sliders on the bidirectional threaded rod move closer to each other, and then the two clamping blocks on the two sliders move closer to each other. Thus, the two clamping blocks can contact and squeeze the support pipe, assemble the support pipe on the riveting machine body, and then the operator places the nut on the support pipe and operates the riveting machine body to perform the riveting of the workpiece nut. With such a structural design, it is convenient for the operator to replace support pipes of different sizes and models, and to a certain extent, it can meet the riveting operations of different nuts for different workpieces, and.

[0023] The following will further elaborate on this application in conjunction with the accompanying Figures 1 to 3 drawings.

[0024] It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size for illustration. Any dimensions are merely exemplary and not restrictive. Additionally, the same reference numerals are used for the same structures, elements, or fittings that appear in more than two figures to represent similar features.

[0025] An embodiment of this application discloses a nut riveting device. Refer to Figures 1 to 3 , a nut riveting device, including a riveting machine body 1. A groove 2 is provided on the processing table of the riveting machine body 1. A chute 3 is provided on the inner wall of the groove 2. A bidirectional threaded rod 4 is rotatably connected inside the chute 3, and one end of the bidirectional threaded rod 4 is arranged outside the riveting machine body 1. A turntable is fixedly connected to the side end of the bidirectional threaded rod 4. A pair of sliders 5 are threadedly connected to the middle of the bidirectional threaded rod 4, and clamping blocks 6 are fixedly connected to the tops of the two sliders 5. Both clamping blocks 6 are arranged inside the groove 2. A support tube 7 for receiving nuts is placed inside the groove 2, and the two clamping blocks 6 are in pressing contact with the outer surface of the support tube 7 (all the electrical components used in this device are powered by an external power source);

[0026] Specifically, insert and place the support tube 7 adapted to the nut to be processed into the groove 2, and then the operator rotates the bidirectional threaded rod 4, causing the two sliders 5 on the bidirectional threaded rod 4 to move closer to each other. Then, the two clamping blocks 6 on the two sliders 5 move closer to each other. Thus, the two clamping blocks 6 can contact and press the support tube 7 to assemble the support tube 7 on the riveting machine body 1. Then, the operator places the nut on the support tube 7 and operates the riveting machine body 1 to perform the riveting of the workpiece nut;

[0027] Through this structural design, it is convenient for the operator to replace support tubes 7 of different sizes and models, and to a certain extent, it can meet the riveting operations of different nuts for different workpieces.

[0028] Refer to Figure 3 , the shape of the chute 3 is convex, and the slider 5 is fully adapted to the chute 3. This design can ensure the stable sliding of the slider 5 in the chute 3 and prevent the slider 5 from shifting or loosening.

[0029] Refer to Figure 3 , the opposite sides of the two clamping blocks 6 are both concave arc-shaped. This design can increase the contact area between the two clamping blocks 6 and the support tube 7, thereby increasing the assembly stability of the support tube 7.

[0030] Refer to Figure 3, rubber gaskets 8 are bonded to the opposite sides of the two clamping blocks 6. With this design, the outer side of the support tube 7 can be contacted and supported by the rubber gaskets 8, thereby increasing the stability of the assembly of the support tube 7 in the groove 2.

[0031] Refer to Figure 1 And Figure 2 , a T-shaped support pad 9 is slidably assembled on the processing table of the riveting machine body 1. When dealing with workpieces with a relatively large area, the T-shaped support pad 9 can be slid so that the top of the T-shaped support pad 9 contacts the bottom of the workpiece, thereby increasing the horizontality of the workpiece placement and ensuring the riveting between the nut and the workpiece.

[0032] All standard parts used in the present utility model can be purchased from the market. Special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here.

[0033] The implementation principle of a nut riveting device in an embodiment of the present application is as follows: First, insert and place the support tube 7 adapted to the nut to be processed into the groove 2. Then, the operator rotates the bidirectional threaded rod 4, causing the two sliders 5 on the bidirectional threaded rod 4 to move closer to each other. Further, the two clamping blocks 6 on the two sliders 5 move closer to each other. Thus, the two clamping blocks 6 can contact and squeeze the support tube 7 to assemble the support tube 7 on the riveting machine body 1. Then, the operator places the nut on the support tube 7 and operates the riveting machine body 1 to perform the riveting of the workpiece nut;

[0034] Moreover, when dealing with workpieces with a relatively large area, the T-shaped support pad 9 can be slid so that the top of the T-shaped support pad 9 contacts the bottom of the workpiece, thereby increasing the horizontality of the workpiece placement and ensuring the riveting between the nut and the workpiece.
