Description

Technical Field

[0001] This utility model relates to the field of riveting equipment technology, and in particular to a riveting gun head with a clamping function. Background Technology

[0002] In modern industrial assembly, riveting technology, as an efficient and reliable connection method, is widely used in aerospace, automotive manufacturing, electronic equipment, and many other industries. However, existing rivet guns have significant drawbacks in actual operation. Their heads only have riveting functionality and lack necessary clamping devices, a design flaw particularly pronounced during riveting operations. During nut riveting, the rivet head needs to rotate into the nut, connect with the nut's threads, and then retract to continue riveting. When the rivet head rotates into the nut to be riveted, due to the lack of effective constraint, the nut cannot be stably fixed and will rotate synchronously under the rivet head's influence. This rotation of the nut not only reduces the accuracy and efficiency of riveting but may also lead to insecure riveting, affecting the overall quality and service life of the product and posing potential safety hazards for subsequent production and use. Summary of the Invention

[0003] According to an embodiment of the present invention, a rivet gun head with a clamping function is provided, comprising:

[0004] Gun tip;

[0005] The clamping head is slidably fitted onto the gun head;

[0006] A spring is fitted onto the gun head, with one end connected to the clamping head and the other end connected to the gun head.

[0007] Furthermore, it also includes: a sliding sleeve, which is slidably fitted onto the gun head, with one end of the sliding sleeve connected to the pressing head and the other end connected to the spring.

[0008] Furthermore, an annular limiting protrusion is provided at the end of the gun head near the clamping head to prevent the sliding sleeve from disengaging from the gun head.

[0009] Furthermore, it also includes: a retaining ring, and the spring end of the retaining ring is connected to the gun head via the retaining ring.

[0010] Furthermore, the gun head is also equipped with an annular groove, in which the retaining spring is engaged.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up a clamping head and spring structure, the nut can be effectively clamped during riveting operations, preventing the nut from rotating with the riveting head, which significantly improves the accuracy and quality of riveting, makes the riveted product more robust and reliable, and extends the service life of the product.

[0013] 2. The design of the sliding sleeve, annular limiting protrusion, snap ring, and annular groove further optimizes the performance of the gun head, making the movement of the pressing head more stable, the installation and fixing of the spring more reliable, and improving the overall stability and reliability of the gun head.

[0014] 3. The design of the rivet gun head with clamping function and the rivet head makes the rivet gun more flexible and efficient in operation, improving the efficiency of rivet operation.

[0015] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0023] First, combine Figures 4-6 The description of the rivet gun head with clamping function according to the embodiment of the present utility model is used for rivetizing nuts and has a wide range of applications.

[0024] like Figures 4-6 As shown, the rivet gun head with clamping function in this embodiment of the present invention includes:

[0025] Gunhead 1;

[0026] Clamping head 2 is slidably sleeved on gun head 1;

[0027] Spring 3 is sleeved on the gun head 1, with one end connected to the clamping head 2 and the other end connected to the gun head 1.

[0028] Furthermore, such as Figures 4-6 As shown, this embodiment also includes a sliding sleeve 4, which is slidably fitted onto the gun head 1. One end of the sliding sleeve 4 is connected to the pressing head 2, and the other end is connected to the spring 3. The sliding sleeve 4 can drive the pressing head 2 to slide on the gun head 1. The sliding sleeve 4 can better guide the sliding of the pressing head 2, making the movement of the pressing head 2 more stable and smooth, and also facilitating the connection and force transmission between the spring 3 and the pressing head 2.

[0029] Furthermore, such as Figure 6 As shown, in this embodiment, an annular limiting protrusion 11 is provided at one end of the gun head 1 near the pressing head 2 to prevent the sliding sleeve 4 from detaching from the gun head 1, ensuring the stability and reliability of the gun head 1 structure, and avoiding the normal progress of the riveting operation due to the sliding sleeve 4 falling off during the riveting process.

[0030] Furthermore, such as Figures 4-6 As shown, in this embodiment, it also includes a retaining ring 5, which is connected to the gun head 1. The end of the spring 3 is connected to the gun head 1 via the retaining ring 5. The use of the retaining ring 5 can easily fix the spring 3 to the gun head 1, and at the same time facilitate the installation and removal of the spring 3, which is beneficial to the maintenance and repair of the gun head 1.

[0031] Furthermore, such as Figure 6 As shown, in this embodiment, the gun head 1 is also provided with an annular groove 12, and the retaining spring 5 is locked in the annular groove 12, which further enhances the connection stability between the retaining spring 5 and the gun head 1, and ensures that the spring 3 will not loosen or fall off during operation.

[0032] Working principle:

[0033] In actual use, first connect the rivet head 1 to the rivet gun body. Place the nut to be riveted in a suitable position, aligning the rivet head with the nut. Before riveting, the clamping head 2, under the action of the spring 3, pre-contacts the nut and applies a certain pressure, pressing the nut tightly against the surface of the workpiece to be riveted, thus tightening the nut.

[0034] When the rivet gun is started for riveting, the rivet head begins to rotate and penetrates into the nut. Since the clamping head 2 has already tightened the nut, the nut will not rotate with the rivet head. After the rivet head completes the riveting operation, the rivet gun stops working. At this time, the clamping head 2 returns to its original position under the elastic restoring force of the spring 3, making it convenient for the next riveting operation.

[0035] Above, refer to Figures 4-6The present invention describes a rivet gun head with a clamping function according to an embodiment of the present invention. By improving the gun head structure, the problem that the existing rivet gun head cannot clamp the nut, causing the nut to rotate with the rivet head during the riveting process is solved, thereby improving the riveting accuracy, efficiency and quality.
