[0016] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Example 1, please refer toFigure 1 - Figure 11 The present invention provides a technical solution for a clamping assembly for tapping rivet nuts: The clamping assembly for tapping rivet nuts includes: an operating table 1, the outer wall of the top of the operating table 1 is rotatably connected to a fixed disk 11, and on one side of the outer wall of the top of the operating table 1 close to the fixed disk 11, a housing 2 is fixedly connected. A placement groove 12 is formed on the outer wall of the top of the fixed disk 11, and a nut body 5 is in movable contact with the inside of the placement groove 12. A replacement structure is arranged on one side of the outer wall of the housing 2. An installation shell 3 is arranged inside the housing 2. An axial hole is formed in the middle position of the installation shell 3, and the inner wall of the axial hole is fixedly connected to the outer wall of a rotating shaft 71. Fixed teeth 31 are fixedly connected to the outer wall of the installation shell 3. A threaded hole is formed above the fixed teeth 31 inside the housing 2, and a pull rod 33 is threadedly connected to the inside of the threaded hole. An installation sleeve is rotatably connected to the lower part of the outer wall of the pull rod 33. A fixed seat 32 is fixedly connected to the outer wall of the bottom of the installation sleeve. A fixed spring 34 is fixedly connected to the outer wall of the top of the fixed seat 32, and the top of the fixed spring 34 is fixedly connected to the upper part inside the housing 2. The inside of the fixed spring 34 is movably sleeved on the outer wall of the pull rod 33.

[0018] Through the threaded connection between the pull rod 33 and the threaded hole, by using the tight fit of the internal and external threads, the pull rod 33 can stay in place when the pull rod 33 stops moving, avoiding that after the operator releases the pull rod 33, the pull rod 33 will be fixed to the fixed teeth 31 again under the action of the fixed spring 34. Correspondingly, the stability after the pull rod 33 stops is increased. When the fixed teeth 31 are fixed through the fixed seat 32, the stability of the installation shell 3 can be increased, avoiding the deviation of the position where the clamping plate 41 is inserted into the placement groove 12 due to the shaking of the installation shell 3. Correspondingly, by fixing the installation shell 3, the accuracy of the movement track of the clamping plate 41 can be increased, and further the working efficiency of the clamping plate 41 is improved.

[0019] Embodiment 2, on the basis of Embodiment 1, the replacement structure includes an L-shaped fixing plate 6. The outer wall of one side of the L-shaped fixing plate 6 is fixedly connected to the outer wall of one side of the housing 2. A motor 61 is fixedly connected to the inner wall of the L-shaped fixing plate 6. The output end of the motor 61 is fixedly connected to a shaft sleeve 62. A square groove 73 is formed on the outer wall of the shaft sleeve 62. A first gear 7 is slidably connected to the outer wall of the shaft sleeve 62. A driving rod 74 is fixedly connected to the inner wall of the first gear 7. A second magnetic block 76 is fixedly connected to one side of the inner wall of the shaft sleeve 62, and the outer wall of one side of the second magnetic block 76 is magnetically attracted to the outer wall of one side of the driving rod 74. The outer wall of the driving rod 74 is slidably connected to the inner wall of the square groove 73. A rotating shaft 71 is rotatably connected through the inside of the housing 2, and a second gear 72 is fixedly connected to the outer wall of the rotating shaft 71. The outer wall of the second gear 72 is meshed with the outer wall of the first gear 7.

[0020] Through the attraction between the driving rod 74 and the second magnet 76, the stability of the driving rod 74 and the first gear 7 can be increased, preventing the first gear 7 from driving the driving rod 74 to move on the square groove 73 during operation. Correspondingly, the stability of the first gear 7 during operation is increased, enabling the first gear 7 to better drive the second gear 72 to move; Through the rotation of the second gear 72, the rotating shaft 71 can drive the mounting shell 3 to rotate, thereby adjusting the clamping plate 41 on the mounting shell 3. This avoids the need for the operator to disassemble and reinstall the clamping plate 41 when it needs to be replaced. Correspondingly, by rotating the mounting shell 3, the purpose of replacing the clamping plate 41 can be achieved, saving the time for replacing the clamping plate 41 and making it more convenient for the operator to replace the clamping plate 41, improving the efficiency of tapping the nut body 5.

[0021] Embodiment 3: On the basis of Embodiment 2, a threaded rod 63 is rotatably connected inside the bushing 62. A driving groove 65 is formed on the outer wall of one end of the threaded rod 63. A first magnet 75 is fixedly connected to the inner wall of the driving groove 65. The outer wall of one side of the first magnet 75 is magnetically attracted to the outer wall of the other side of the driving rod 74. The inside of the driving groove 65 is movably sleeved with the outer wall of the driving rod 74. A handle 64 is fixedly connected to the outer wall of the threaded rod 63 outside the housing 2.

[0022] Through the setting of the handle 64, it is avoided that the insertion of the driving rod 74 is affected when the driving groove 65 and the driving rod 74 are not aligned. Correspondingly, the efficiency of inserting the driving rod 74 into the inside of the driving groove 65 is increased, ensuring that the two can be smoothly docked without repeated attempts at alignment and insertion, reducing the operation time and labor cost.

[0023] The driving rod 74 limits the threaded rod 63. At this time, when the motor 61 works, the driving rod 74 can drive the threaded rod 63 to rotate accordingly. Through the setting of the driving rod 74 and the first gear 7, the rotation of the threaded rod 63 and the rotating shaft 71 can be flexibly adjusted. Correspondingly, in one state, the first gear 7 and the driving rod 74 cannot drive the threaded rod 63 and the rotating shaft 71 to move simultaneously, preventing the movement trajectories of the threaded rod 63 and the rotating shaft 71 from conflicting and ensuring the independence of the movement of the threaded rod 63 and the rotating shaft 71.

[0024] Embodiment 4. On the basis of Embodiment 3, a moving block 86 is threadedly connected to the outer wall of the threaded rod 63. A guiding ring 87 is fixedly connected to the outer wall of the top of the moving block 86. The inner part of the guiding ring 87 is slidably connected to the outer wall of the rotating shaft 71. A stress plate 8 is fixedly connected to the outer wall of the bottom of the moving block 86. A push rod 82 is fixedly connected to the outer wall of one side of the stress plate 8. A cavity is formed in the push rod 82. A T-shaped plate 84 is slidably connected to the inner part of the cavity. A positioning plate 83 is fixedly connected to the outer wall of the T-shaped plate 84. A pushing spring 85 is fixedly connected to the outer wall of one side of the T-shaped plate 84. One end of the pushing spring 85 is fixedly connected to the inner wall of the cavity. The outer wall of the positioning plate 83 is movably inserted into a positioning groove 81. Three positioning grooves 81 are formed in the outer wall of one side of the mounting shell 3.

[0025] After the positioning plate 83 is fixed inside the positioning groove 81, when the stress plate 8 continues to push the push rod 82 to move into the cylindrical groove 42, since the push rod 82 can slide on the T-shaped plate 84 at this time, the stability of the push rod 82 can be increased, the shaking of the push rod 82 during the movement process can be avoided, and correspondingly, the smoothness of the push rod 82 is increased, making the process of the push rod 82 pushing the moving clamping rod 4 smoother.

[0026] Embodiment 5. On the basis of Embodiment 3, three cylindrical grooves 42 are formed in the mounting shell 3. A limiting plate I 43 is fixedly connected to the inner part of the three cylindrical grooves 42. A clamping rod 4 is slidably penetrated through the inner part of the limiting plate I 43. A clamping plate 41 is fixedly connected to one end of the clamping rod 4. A limiting plate II 44 is fixedly connected to the outer wall of the clamping rod 4. A reset spring 45 is fixedly connected to the outer wall of one side of the limiting plate II 44. One end of the reset spring 45 is fixedly connected to the inner wall of the cylindrical groove 42.

[0027] When the clamping plate 41 is pushed by the clamping rod 4 to contact the nut body 5 and then continues to move forward, the other side of the nut body 5 can be closely contacted with the inner wall of the placing groove 12, so that the nut body 5 can be fixed, the movement of the nut body 5 during the tapping process can be avoided, and correspondingly, the stability of the nut body 5 is increased.

[0028] During actual use, by the operator rotating the pull rod 33, the pull rod 33 can move upward along the inside of the threaded hole. Subsequently, through the movement of the pull rod 33, the mounting sleeve can drive the fixed seat 32 to move accordingly. Then, through the upward movement of the fixed seat 32, it can leave the outer wall of the fixed tooth 31, thereby releasing the fixation of the fixed seat 32 to the fixed tooth 31. By releasing the fixation between the fixed seat 32 and the fixed tooth 31, the mounting shell 3 can rotate along with the rotating shaft 71, thus releasing the fixation of the mounting shell 3. Through the threaded connection between the pull rod 33 and the threaded hole, using the tight fit of the internal and external threads, the pull rod 33 can stay in place when it stops moving, avoiding the situation that after the operator releases the pull rod 33, the pull rod 33 will be fixed to the fixed tooth 31 again under the action of the fixed spring 34. Correspondingly, the stability after the pull rod 33 stops is increased. Then, when the fixed seat 32 fixes the fixed tooth 31, the stability of the mounting shell 3 can be increased, avoiding the deviation of the position where the clamping plate 41 inserted into the placement groove 12 due to the shaking of the mounting shell 3. Correspondingly, by fixing the mounting shell 3, the accuracy of the movement track of the clamping plate 41 can be increased, further improving the working efficiency of the clamping plate 41.

[0029] When releasing the fixation of the mounting shell 3, and then by the operator pushing the first gear 7, subsequently through the movement of the first gear 7, the first gear 7 can drive the driving rod 74 to move inside the square groove 73. When the driving rod 74 moves to one end of the square groove 73, while the driving rod 74 is magnetically attracted to the second magnet 76, the first gear 7 can be meshed with the second gear 72. Through the attracting effect between the driving rod 74 and the second magnet 76, the stability of the driving rod 74 and the first gear 7 can be increased, avoiding the situation that the first gear 7 drives the driving rod 74 to move on the square groove 73 during operation. Correspondingly, the stability of the first gear 7 during operation is increased, so that the first gear 7 can better drive the second gear 72 to move.

[0030] At this time, start the motor 61 on the L-shaped fixing plate 6 to work. Subsequently, through the work of the motor 61, the bushing 62 can rotate accordingly. Then, through the fixed connection between the driving rod 74 and the first gear 7, when the bushing 62 drives the driving rod 74 to rotate, the driving rod 74 can drive the first gear 7 to move accordingly. Subsequently, through the movement of the first gear 7, the second gear 72 can rotate accordingly. Then, by using the rotation of the second gear 72, the rotating shaft 71 can drive the mounting shell 3 to rotate, thereby adjusting the clamping plate 41 on the mounting shell 3, avoiding the situation that when the clamping plate 41 needs to be replaced, the operator needs to disassemble and reinstall it. Correspondingly, by rotating the mounting shell 3, the purpose of replacing the clamping plate 41 can be achieved, saving the time for replacing the clamping plate 41, and making it more convenient for the operator to replace the clamping plate 41, improving the efficiency of tapping the nut body 5.

[0031] It should be noted that: by changing the internal shape of the clamping plate 41, the nut body 5 of different shapes can be replaced, so as to better fix the nut body 5.

[0032] After the replacement of the clamping plate 41 is completed, the movement of the motor 61 is stopped, and then the fixed seat 32 is reinserted into the interior of two teeth of the fixed teeth 31, so that the installation shell 3 can be fixed. Then, the first gear 7 is pushed, and the driving rod 74 and the second magnet 76 are separated by the force on the first gear 7, so that the driving rod 74 can move from one end of the square groove 73 to the other end. When the driving rod 74 moves to the other end of the square groove 73, the driving rod 74 can be inserted into the interior of the driving groove 65 and magnetically attracted to the first magnet 75. At this time, the meshing connection between the first gear 7 and the second gear 72 can be released, and the driving rod 74 can limit the threaded rod 63. At this time, when the motor 61 works, the driving rod 74 can drive the threaded rod 63 to rotate accordingly. Through the setting of the driving rod 74 and the first gear 7, the rotation of the threaded rod 63 and the rotating shaft 71 can be flexibly adjusted. Correspondingly, the first gear 7 and the driving rod 74 cannot drive the threaded rod 63 and the rotating shaft 71 to move simultaneously in one state, preventing the movement trajectories of the threaded rod 63 and the rotating shaft 71 from conflicting and ensuring the independence of the movement of the threaded rod 63 and the rotating shaft 71.

[0033] Through the setting of the handle 64, when the operator pushes the driving rod 74 into the interior of the driving groove 65, if the driving groove 65 is not aligned with the driving rod 74, the operator can rotate the handle 64, and then through the movement of the handle 64, the threaded rod 63 can be driven to rotate accordingly, so as to drive the driving groove 65 to adjust the angle, facilitating the insertion of the driving rod 74 into the interior of the driving groove 65, avoiding the influence on the insertion of the driving rod 74 when the driving groove 65 and the driving rod 74 are not aligned, correspondingly increasing the efficiency of inserting the driving rod 74 into the interior of the driving groove 65, ensuring that the two can be smoothly docked, without repeatedly trying to align and insert, reducing the operation time and labor cost.

[0034] Through the rotation of the threaded rod 63, the moving block 86 can be driven to move. Then, through the movement of the moving block 86, the guide ring 87 and the stress plate 8 can be driven to move simultaneously. By sliding the guide ring 87 on the rotating shaft 71, the movement direction of the moving block 86 can be limited, avoiding deviation of the moving block 86 during movement, correspondingly increasing the stability of the movement of the moving block 86 and improving the movement efficiency of the moving block 86.

[0035] Through the movement of the force-bearing plate 8, the push rod 82 can drive the positioning plate 83 to move. Then, through the pushing spring 85 arranged inside the push rod 82, the T-shaped plate 84 can drive the positioning plate 83 to always be on the side close to the mounting shell 3. At this time, when the push rod 82 drives the positioning plate 83 to insert into the inside of the cylindrical groove 42, the positioning plate 83 can be inserted into the inside of the positioning groove 81 first. By inserting the positioning plate 83 into the inside of the positioning groove 81, the movement of the push rod 82 can be limited, so that the push rod 82 can be inserted into the inside of the cylindrical groove 42 more stably. After the positioning plate 83 is fixed in the positioning groove 81, when the force-bearing plate 8 continues to push the push rod 82 to move into the inside of the cylindrical groove 42, since the push rod 82 can slide on the T-shaped plate 84 at this time, the stability of the push rod 82 can be increased, avoiding the push rod 82 from shaking during the movement process, correspondingly increasing the smoothness of the push rod 82, and making the process of the push rod 82 pushing the moving clamping rod 4 smoother.

[0036] Then, when the push rod 82 pushes the clamping rod 4, the clamping rod 4 can drive the clamping plate 41 to move out of the inside of the housing 2 and insert into the inside of the placement groove 12, so as to clamp and fix the nut body 5 inside the placement groove 12. When the clamping rod 4 pushes the clamping plate 41 to contact the nut body 5 and then continues to move forward, the other side of the nut body 5 can be in close contact with the inner wall of the placement groove 12, so as to fix the nut body 5, avoiding the nut body 5 from moving during the tapping process, and correspondingly increasing the stability of the nut body 5.

[0037] It should be noted that: rubber pads are provided on the surfaces of the placement groove 12 and the clamping plate 41 that contact the nut body 5. Through the setting of the rubber pads, while increasing the friction between the nut body 5 and the placement groove 12 and the clamping plate 41, it can also play a buffering role for them.

[0038] Through the cooperation of the first limiting plate 43 and the second limiting plate 44, after the second limiting plate 44 moves to the position of the first limiting plate 43, it can be blocked, avoiding the clamping rod 4 from completely sliding out of the inside of the cylindrical groove 42 and making it inconvenient for the clamping rod 4 to enter the inside of the cylindrical groove 42 again. Correspondingly, when the clamping plate 41 finishes clamping the nut body 5, it is convenient for the clamping plate 41 to return to its original position, and at the same time, it can also limit the length of the clamping rod 4 moving out of the inside of the cylindrical groove 42, avoiding the length of the clamping rod 4 moving out of the inside of the cylindrical groove 42 being too long and clamping the nut body 5 too tightly to cause deformation of the nut body 5. Correspondingly, by limiting and controlling the length of the nut body 5 moving out, the clamping force of the nut body 5 can be controlled.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
