They are used to permanently join materials such as metals and plastics through snap fasteners. As industrial manufacturing gradually moves towards higher precision, higher reliability, and miniaturization, the precision requirements of riveting processes for various products have significantly increased. During the riveting process, the precision and accuracy of the snap fastener position directly affect the riveting quality and efficiency.

However, the riveting precision and accuracy of existing riveting machines are relatively poor and cannot meet the current high-quality requirements of industrial riveting, which needs to be addressed. Utility Model Content

[0003] The main purpose of this invention is to propose a correction mechanism for riveting, which aims to solve the technical problem of poor riveting accuracy and precision in existing riveting machines.

[0004] To achieve the above objectives, this utility model proposes a correction mechanism for riveting, including a driving mechanism, a pushing mechanism, and a snapping mechanism. One end of the pushing mechanism is connected to the driving mechanism, and the other end is connected to the snapping mechanism. The driving mechanism includes a motor and a driving component. The pushing mechanism includes a correction component for correcting the pushing direction and a limiting component for stabilizing the connection of the correction component. The correction component is at least abutted against at least one of the driving mechanism or the snapping mechanism. The correction component includes a flat end and a cylindrical end, and the limiting component is abutted against the flat end.

[0005] Furthermore, the flat end is provided with a through mounting hole, and the limiting component includes a screw, a nut and a washer. While the screw passes through the mounting hole, one side of the flat end abuts against the nut, and the other side abuts against the washer.

[0006] Furthermore, the flat end is provided with a stepped surface to enhance the stability of the limiting component, and the stepped surface abuts against the nut and washer.

[0007] Furthermore, the stepped surface is defined as an outer ring that surrounds the mounting hole and gradually decreases in size.

[0008] Furthermore, the cylindrical end includes a connecting channel that extends through itself and has an opening at the end away from the flat end, and the pushing mechanism also includes an adjusting rod that extends at least partially into the connecting channel for setting.

[0009] Furthermore, the cylindrical end includes a first connecting portion and a second connecting portion, wherein the periphery of the second connecting portion is wider than the periphery of the first connecting portion.

[0010] Furthermore, the adjusting link includes an extended portion and a thickened portion, with the thickened portion positioned between the extended portions.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0026] This utility model proposes a correction mechanism for riveting.

[0027] In this embodiment of the utility model, such as Figures 1 to 6As shown, the correction mechanism can be installed inside the riveting machine and is used to correct horizontal movement during riveting. It includes a drive mechanism 1, a push mechanism 2, and a snap-fit ​​mechanism 3. One end of the push mechanism 2 is connected to the drive mechanism 1, and the other end is connected to the snap-fit ​​mechanism 3. The drive mechanism 1 includes a motor 11 and a drive component 12. The push mechanism 2 includes a correction component 21 for correcting the pushing direction and a limiting component 22 for stabilizing the connection of the correction component 21. The correction component 21 is at least connected to at least one of the drive mechanism 1 or the snap-fit ​​mechanism 3. The correction component 21 includes a flat end 211 and a cylindrical end 212. The limiting component 22 is set to abut against the flat end 211. Through the stable connection between the correction component 21 and the limiting component 22, the limiting component 22 exerts a certain limiting effect on the correction component 21. Thus, when the drive mechanism 1 drives the push mechanism 2, the push mechanism 2 can be restricted to move within an accurate range in the pushing direction, thereby achieving precise riveting.

[0028] In an embodiment of this utility model, the flat end 211 is provided with a through mounting hole 2111. The limiting component 22 includes a screw 221, a nut 222, and a washer 223. When the screw 221 passes through the mounting hole 2111, one side of the flat end 211 abuts against the nut 222, and the other side abuts against the washer 223. Specifically, the limiting component 22 locks and limits the straightening component 21 by the washer 223 and the nut 222 abutting against the flat end 211, thus achieving a stable limiting performance. At the same time, the locking and unlocking of the nut 222 facilitates assembly and disassembly. The nut 222 can be set in various forms. The internal hexagonal structure shown in the embodiment of this utility model can be used. Other common or irregular structures are detailed in the prior art and will not be described here.

[0029] Specifically, in order to further facilitate the limiting effect on the correction component, the flat end 211 is provided with a stepped surface 2112 for cooperating to enhance the stability of the limiting component 22. The stepped surface 2112 abuts against the nut 222 and the washer 223. In some preferred embodiments of the present invention, the stepped surface 2112 is preferably a hollow cylinder integrally formed on the surface of the correction component 21 and protruding. The end face of the stepped surface 2112 is flat. This structure is beneficial for the abutment of the washer 223 and the nut 222.

[0030] More specifically, in order to further strengthen the connection between the correction component 21 and the limiting component 22, the stepped surface 2112 is defined as an outer ring that surrounds the mounting hole 2111 and gradually decreases in size. The reduced outer ring can accommodate washers 223 and nuts 222 of more sizes. At the same time, the reduced outer ring can easily abut against the washers 223 and nuts 222, and the structure will be more stable because it is wrapped by the abutting washers 223 and nuts 222.

[0031] In an embodiment of this utility model, the cylindrical end 212 includes a connecting channel 2121 that passes through itself and has an opening at one end away from the flat end 211. The pushing mechanism 2 also includes an adjusting rod 23. The adjusting rod 23 extends at least partially into the connecting channel 2121. By filling the adjusting rod 23 with the connecting channel 2121, a stable connection relationship can be formed. After the adjusting rod 23 extends into the connecting channel 2121, it can maintain consistency with the correction component 21. This structure ensures the stable advancement of the pushing mechanism 2 in the accurate direction.

[0032] Specifically, the cylindrical end 212 includes a first connecting portion 2122 and a second connecting portion 2123. The outer periphery of the second connecting portion 2123 is wider than the outer periphery of the first connecting portion 2122. The wider outer periphery of the second connecting portion 2123 is beneficial to the stability of the connection.

[0033] Specifically, the adjusting link 23 includes an elongated portion 231 and a thickened portion 232. The thickened portion 232 is disposed between the elongated portions 231. Understandably, due to its relatively long length, the adjusting link 23 may experience abnormal swaying during horizontal movement. By providing the thickened portion 232 between the elongated portions 231, the rigidity of the adjusting link 23 can be increased. At the same time, the weight of the middle section of the adjusting link 23 is increased, preventing swaying during the advancement process. In some preferred embodiments of this utility model, the elongated portion 231 and the thickened portion 232 are integrally formed. The advantage of integral forming is that it can make the structure more stable.

[0034] In this embodiment of the invention, the motor 11 is defined as a stepper motor, which provides smooth and stable movement. The drive component 12 is defined as an eccentric wheel. The limiting component 22 is connected to the end of the drive component 12. The flat end 211 of the correction component 21 is connected to the drive component 12 via the limiting component 22. The rotation range of the drive component 12 is limited to a flat angle. During the operation of the motor 11, the limiting component 22 is driven by the motor 11 to rotate at a flat angle, thereby driving the correction component 21 to move. The correction component 21 remains stationary. Figures 1 to 2 The directional state is shifted to the other end of the eccentric wheel, and the adjusting link 23 pushes the buckling mechanism 3 forward to achieve precise arrival of the riveting position.

[0035] Specifically, in order to maintain the stability between the drive component 12 and the motor 11, the drive component 12 is provided with a receiving chamber 121. The receiving chamber 121 is provided with a locking member 122 for locking the drive component 12. The locking member 122 can lock the drive component 12 and make it hold the motor 11, so that the motor 11 can stably drive the drive component 12 to rotate.

[0036] In an embodiment of this utility model, a sensing component 4 is provided at the origin of the driving mechanism 1 that drives the pushing mechanism 2. The sensing component 4 includes a sensing frame 41 and a sensor 42. The function of the sensing component 4 is to sense whether the pushing mechanism 2 is at the origin and to realize a regular pushing action, thereby enhancing the pushing accuracy of the pushing mechanism 2. In addition, the motor 11 is provided with a motor frame 111, and the sensing frame 41 is fixedly connected to the motor frame 111. The sensor 42 is then placed on the sensing frame 41 to maintain a stable sensing operation.

[0037] In an embodiment of this utility model, the buckling mechanism 3 includes a buckling module (not shown) and a frame 31. The buckling module is mounted on the frame 31. The pushing mechanism 2 is connected to the frame 31 through a correction component 21, and the flat end 211 of the correction component 21 is connected to the frame 31. The pushing mechanism 2 moves the frame 31 horizontally, thereby affecting the movement of the buckling module, and thus achieving high-accuracy buckling with a stable pushing step.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
