Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1 A riveting fixture includes a support rod 1, a pressure seat 15 installed at one end of the support rod 1, a force-applying mechanism installed in the middle, and a pressure seat 16 slidably installed between the pressure seat 15 and the force-applying mechanism. The force-applying mechanism includes a first sliding sleeve 2 slidably connected to the support rod 1. The first sliding sleeve 2 and the support rod 1 are locked together by a rake tooth structure. The first sliding sleeve 2 is rotatably connected to a lever 17 through a second hinge 13. The short arm end of the lever 17 abuts against the pressure seat 16.

[0020] The support rod 1 serves as the skeleton structure of the entire riveting fixture, with one end fixed to the pressure seat 15, providing a stable support surface for the rivet. The pressure seat 16 can slide along the support rod 1 and is installed between the pressure seat 15 and the force application mechanism. It is used to support the forming mold and directly act on the tail of the rivet. The force application mechanism is slidably engaged with the support rod 1 by the first sliding sleeve 2. The first sliding sleeve 2 is locked to the support rod 1 in different positions through a rake tooth structure, realizing adjustment according to the workpiece thickness and rivet length. The lever 17 is rotatably connected to the first sliding sleeve 2 through the second hinge 13, and the short arm end of the lever 17 abuts against the pressure seat 16. When the operator presses the long arm of the lever 17, the short arm end applies amplified pressure to the pressure seat 16, causing the pressure seat 16 to push the mold and compress the tail of the rivet, resulting in plastic deformation, thereby completing the riveting.

[0021] This riveting fixture, through the rational coordination of support rod 1, pressure bearing seat 15, pressure applying seat 16, first sliding sleeve 2, rake tooth structure, second hinge 13, and lever 17, constitutes a purely manual pressure transmission and amplification system. The lockable nature of the rake tooth structure allows the position of the first sliding sleeve 2 on the support rod 1 to be flexibly adjusted to accommodate rivets of different specifications and lengths; lever 17 utilizes the lever arm difference to achieve significant force amplification, enabling the operator to obtain sufficient rivet deformation pressure with relatively small hand force; the sliding structure of the pressure applying seat 16 ensures the centering and stability of the pressing process, thus making the riveting quality reliable, the operation labor-saving, and suitable for portable use.

[0022] This device has a simple structure, relies entirely on manual force application, is easy to carry, and is suitable for manual pressure riveting fixtures for soft rivets. It can be operated flexibly without external power and meets the needs of various applications such as light assembly and on-site maintenance.

[0023] The lever 17 includes a short arm 12 and a long arm 14, which are set at an obtuse angle. The second hinge 13 is rotatably connected at the intersection of the short arm 12 and the long arm 14. The end of the short arm 12 abuts against the pressure seat 16. A roller 11 is installed at the end of the short arm 12.

[0024] The end of the short arm 12 abuts against the pressure seat 16 and is equipped with a roller 11. When the operator pushes the long arm 14, the lever 17 rotates around the second hinge 13. The input force generated by the long arm 14 is amplified and transmitted to the short arm 12 through the lever principle. With the assistance of the roller 11, the short arm 12 smoothly applies pressure to the pressure seat 16, causing it to move forward and push the mold to press the tail of the rivet for plastic forming.

[0025] The rake tooth structure includes rake teeth 4, one end of which is rotatably connected to a first sliding sleeve 2 via a first hinge 3. A plurality of rake grooves 5 are provided on the support rod 1 for the rake teeth 4 to be inserted into. The rake teeth 4 can be removed from the rake grooves 5, the position of the first sliding sleeve 2 adjusted, and then the rake teeth 4 can be reinserted into the rake grooves 5. It is simple and convenient to use. In one embodiment, the rake teeth 4 and the rake grooves 5 can be magnetically connected or interference-fitted.

[0026] The pressure-bearing seat 15 includes an anvil plate 7 fixedly connected to the support rod 1, and an anvil 8 is installed on one side of the anvil plate 7; the anvil plate 7 has a first groove, and the anvil 8 is detachably embedded in the first groove; the pressure-applying seat 16 includes a second sliding sleeve 6 slidably connected to the support rod 1, and a movable plate 9 is fixedly connected to the second sliding sleeve 6; a forming die 10 is installed on one side of the movable plate 9; the movable plate 9 has a second groove, and the forming die 10 is detachably embedded in the second groove.

[0027] The pressure-bearing seat 15 is fixed to one end of the support rod 1 and consists of an anvil plate 7 and an anvil 8. The anvil plate 7 is firmly connected to the support rod 1, providing rigid support for riveting. A first groove is provided on the anvil plate 7, and the anvil 8 is detachably embedded in this groove, allowing for the replacement of suitable anvils according to different specifications or shapes of rivets. The pressure-applying seat 16 is slidably engaged with the support rod 1 and consists of a second sliding sleeve 6, a movable plate 9, and a forming die 10. The second sliding sleeve 6 moves along the support rod 1 to accommodate different workpiece thicknesses, and the forming die 10, mounted on one side of the movable plate 9, directly acts on the tail of the rivet. A second groove is provided on the movable plate 9, and the forming die 10 is detachably embedded therein, facilitating the replacement of dies of different shapes or specifications. During riveting, the rivet head is supported on the anvil 8, and the forming die 10 is pressed against the tail of the rivet by the force-applying mechanism, causing the rivet to undergo plastic deformation and complete the connection.

[0028] The fixed connection between the anvil plate 7 and the support rod 1 ensures the stability of the pressure-bearing part. The structure of the first groove and the detachable anvil 8 improves the tool's adaptability to different rivet specifications and the convenience of maintenance. The sliding fit of the second sliding sleeve 6 allows the pressure seat 16 to be flexibly adjusted to adapt to workpieces of different thicknesses. The fit between the movable plate 9 and the forming die 10 provides a mold support for the precise forming of the rivet tail. The detachable design of the second groove facilitates quick mold replacement and reduces the preparation time when changing to different specifications.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
