[0032] See Figures 1 to 2 As shown, this utility model provides a simple guarantee tooling, including:

[0033] Support block 1, which is provided with mounting holes and adjustment holes;

[0034] Positioning pin 2, wherein the positioning pin 2 is disposed in the mounting hole, and both ends of the positioning pin 2 extend out from the mounting hole respectively;

[0035] The clamping block 3 is set in the adjusting hole via an adjusting rod 4. The adjusting rod 4 is also provided with a locking part, which is used to lock the position of the adjusting rod 4. The adjusting rod 4 is used to axially limit the clamping block 3.

[0036] It should also be noted that, during use, the positioning pin 2 is first inserted into the corresponding hole of the inner skin 8. The seat belt reinforcement 7 also has a mounting part, which is cylindrical and is used to fit onto the positioning pin 2.

[0037] For example, the positioning pin 2 is further provided with a positioning part 5, which is a stepped annular structure. The positioning part 5 is fixedly sleeved on the positioning pin 2. The outer diameter of the positioning part 5 is larger than the diameter of the mounting hole. The upper step of the positioning part 5 is used to position the seat belt reinforcement, and the lower step of the positioning part 5 is used to position the inner skin. The positioning part 5 is clearance-fitted with the positioning seat belt reinforcement and the inner skin.

[0038] It should also be noted that the purpose of setting the positioning part 5 is to further position the simple guarantee tooling of this application by using the positioning part 5 and the holes on the inner skin 8 during installation, so as to ensure that the simple guarantee tooling of this application is in an accurate position during installation.

[0039] Furthermore, the clamping block 3 can be welded onto the adjusting rod 4. By utilizing the fit between the threads, the clamping block 3 can be positioned precisely on the corresponding positioning pin 2 to complete the clamping when the adjusting rod 4 rotates and moves.

[0040] It should also be noted that the clamping block 3 is movably sleeved on the adjusting rod 4. A nut is set at the end of the adjusting rod 4. The nut drives the clamping block 3 to move and adjust the clamping block 3 above the corresponding positioning pin 2. Rotating the adjusting rod 4 causes the adjusting rod 4 to move axially, while the nut on the adjusting rod 4 squeezes the clamping block 3, pressing the clamping block 3 onto the corresponding positioning pin 2.

[0041] For example, the positioning part 5 is integrally formed with the positioning pin 2.

[0042] It should also be noted that the positioning part 5 is integrated with the positioning pin 2. The purpose is to limit the axial movement of the positioning pin 2 when the positioning pin 2 is placed in the corresponding mounting hole, so as to avoid the axial position of the positioning pin 2 being inaccurate every time, which would affect the clamping and welding effect.

[0043] For example, the end of the positioning pin 2 away from the support block 1 is provided with a guide portion, and the guide portion and the positioning portion 5 are located on the same side of the support block 1.

[0044] It should also be noted that the purpose of setting the guide part is to ensure that the seat belt reinforcement 7 can be smoothly set on the positioning pin 2 when installing the seat belt reinforcement 7. In order to ensure the stability of the seat belt reinforcement 7, its inner wall needs to be in close contact with the positioning pin 2. Without the guide part, it would be more difficult to align during installation.

[0045] For example, the inner wall of the adjusting hole is threaded, the outer wall of the adjusting rod 4 is threaded, the adjusting rod 4 is threaded in the adjusting hole, the adjusting rod 4 is fixedly connected to the pressing block 3, and the threaded part of the adjusting rod 4 forms the locking part.

[0046] It should also be noted that the threads on the inner wall of the adjusting hole are designed to limit the axial movement of the adjusting rod 4. The threaded connection allows the adjusting rod 4 to move axially and move the clamping block 3 closer to the end of the positioning pin 2, thus maintaining the clamping state.

[0047] For example, the clamping block 3 is provided with a clamping block near the end of the positioning pin 2. The clamping block is arranged in an arc shape toward the end face of the positioning pin 2. The clamping block is used to press the seat belt reinforcement 7 into the end of the positioning pin 2.

[0048] It should also be noted that the purpose of the clamping block is to improve clamping performance. Furthermore, the clamping surface of the clamping block is designed with an arc shape. This arc shape allows for better contact with the surface of the object being clamped, especially when the object's surface is curved or rounded. This closer fit not only improves clamping stability but also helps reduce stress concentration during clamping, protecting the object from damage. The arc shape can accommodate objects of different shapes and sizes. By adjusting the curvature and size of the arc shape, effective clamping of objects of various shapes can be achieved, improving the tool's versatility and flexibility.

[0049] For example, the guide portion is integrally formed with the positioning pin 2, and the guide portion is frustum-shaped.

[0050] It should also be noted that, in order to make it easier to fit the seat belt reinforcement 7 onto the positioning pin 2 when placing it, the end of the positioning pin 2 is guided by an inverted frustum structure.

[0051] In one embodiment, the positioning pin 2 is transitionally fitted with the mounting hole, and a locking nut is provided at the end of the positioning pin 2 away from the guide portion for fastening.

[0052] For example, the outer wall of the positioning pin 2 away from the guide portion is also provided with threads, the inner wall of the mounting hole is provided with threads, and the positioning pin 2 is threadedly connected to the mounting hole.

[0053] It should also be noted that the thread on the outer wall of the locating pin 2 is to solve the axial limitation of the locating pin 2, and to adjust the axial position of the locating pin 2 by means of the thread and keep it stationary.

[0054] For example, the threaded end of the positioning pin 2 extends out of the mounting hole, and a locking nut is provided on the extended end.

[0055] It should also be noted that, furthermore, a locking nut is provided at the threaded end of the positioning pin 2 in order to further improve the axial limiting capability of the positioning pin 2. The positioning part 5 can be used for limiting at one end of the positioning pin 2, and the locking nut can be used for limiting at the other end of the positioning pin 2.

[0056] For example, the support block 1 is also provided with a pad block 6, which is used to contact the vehicle inner skin 8 to increase the contact area and improve the positioning effect.

[0057] To improve the adaptability of the workpiece, the pad 6 can be designed to be detachable. A mounting groove is pre-set on the support block 1. The mounting groove is a mortise and tenon structure mounting groove. The pad 6 is embedded in the mounting groove. The pad 6 can be replaced by lateral disassembly. At the same time, the insertion end of the pad 6 can be further set as a magnetic component, so that the pad 6 is not easy to fall off after being inserted into the mounting groove. Different pads 6 can be used for support and positioning for different working conditions.

[0058] It should also be noted that, in order to provide positioning during installation, a pad 6 is set on the support block 1. The upper end face of the pad 6 is tilted, and its tilt angle matches the curvature of the corresponding inner skin 8 surface.

[0059] Furthermore, a buffer pad is provided on the end face of the pad 6 facing the inner skin 8. The buffer pad can be made of rubber to protect the contact surface of the inner skin 8.

[0060] In summary, the simple guarantee tooling of this utility model has the following characteristics: when in use, the positioning pin 2 is first inserted into the corresponding hole in the inner skin 8 of the vehicle, then the support block 1 is placed under the inner skin 8 for support, the seat belt reinforcement 7 is sleeved on the positioning pin 2, and the position of the adjusting rod 4 is adjusted axially so that the clamping block 3 presses the seat belt reinforcement 7 on the positioning pin 2. The clamping process of welding occupies little space and is easy to disassemble, which can quickly complete the welding work of the seat belt reinforcement 7.

[0061] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
