[0002] Due to their superior metallic properties, aluminum alloy castings are widely used in a wide range of fields, including aerospace, shipbuilding, power generation, and automotive. Due to the inherently low strength of aluminum alloys and the inconvenient processing of their structures, higher-strength steel bushings or other standard steel components are often used in key joints to increase strength. Some standard components, such as support nuts, are often fastened using riveting. The main advantages of riveting include high connection strength, excellent precision, simple equipment, low cost, minimal deformation, excellent fatigue resistance, and insensitivity to stress concentration.

[0033] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0034] It should be noted that: unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present invention belongs. The words "one", "an" or "the" and the like used in the specification and claims of the present utility model patent application do not express quantity restrictions, but rather indicate the presence of at least one; the words "first", "second" and "third" used herein shall not be regarded as restrictions on the order of components, but merely serve to distinguish different components; words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0035] In order to more clearly describe the specific structure of the narrow space support nut riveting tooling, combined with the attached Figure 1-7 Describe this embodiment:

[0036] Figure 1 The figure shows the riveting tool being used on the product 2; Figure 2 The mounting position on the product part 2 is shown, and the mounting position has a bolt hole and a rivet hole; Figure 3 The shape of the support plate nut standard part 4 is shown. The support plate nut standard part includes a support plate with a rivet hole and a nut protrusion with a threaded hole. Assembly is required before riveting: the threaded hole of the support plate nut standard part is aligned with the bolt hole of the product part 2, the rivet hole of the support plate nut standard part is aligned with the rivet hole of the product part 2, and after the rivet 3 is passed through the corresponding rivet hole, the nail cap of the rivet 3 is on the lower side of the installation position of the product part 2, and the riveted end of the rivet 3 extends to the upper side of the support plate nut standard part 4.

[0037] See Figure 4 and Figure 5 The present invention is a support plate nut riveting tool for a narrow space, which includes a fixing block 1, the fixing block 1 includes a connecting portion 101, and an upper mounting portion 102 and a lower mounting portion 103 located at both ends of the connecting portion 101 and capable of extending to both sides of the installation position of the product part 2 to be riveted; a lateral accommodating cavity 104 is formed between the upper mounting portion 102 and the lower mounting portion 103 for accommodating the rivet 3 and the support plate nut standard part 4 assembled on the product part 2; the lower mounting portion 103 has a supporting surface 1031 for supporting the nail cap of the rivet 3; a positioning member 5 is clamped on the lower mounting portion 103 and can be threadedly connected to the support plate nut standard part 4 to achieve fixed positioning of the lower mounting portion 103, the support plate nut standard part 4 and the product part 2; a hexagonal bolt 6 is threadedly connected to the upper mounting portion 102, which corresponds one-to-one to the rivet 3 and can rotate and apply pressure toward the riveted end of the rivet 3.

[0038] During riveting, the support surface 1031 supports the cap of the rivet 3, and a hexagonal wrench is used to drive the hexagonal bolt 6 to squeeze the riveted end of the rivet 3 to complete the riveting. This operation takes up little space and solves the problem of conventional riveting methods being unable to be implemented in narrow structural locations. The positioning member 5, which is threadedly connected to the support plate nut standard member 4, fixes the lower mounting portion 103, the support plate nut standard member 4, and the product part 2 in a fixed position, ensuring the stability of the riveting process and the accuracy of the riveting position.

[0039] The upper mounting portion 102 of the fixing block 1 is provided with a threaded hole adapted to fit the hexagonal bolt 6 .

[0040] See Figure 5 , the design height of the accommodating cavity 104 should be greater than the length of the rivet 3 used; Figure 4The accommodating cavity 104 is open on three sides, and the three open side surfaces of the fixing block 1 are divided into a product-facing surface 105 and adjacent surfaces 106 on both sides of the product-facing surface 105. The product-facing surface 105 is perpendicular to the placement direction of the fixing block 1 relative to the product 2.

[0041] The lower mounting portion 103 is provided with a slot 107 that penetrates the lower mounting portion 103 along the axial direction of the positioning member 5. The slot 107 extends laterally through the product-facing surface 105. The positioning member 5 can slide laterally in the slot 107 (slide in a direction perpendicular to the axis of the positioning member 5). After loosening the positioning member 5, the positioning member 5 and the fixing block 1 can be quickly disassembled without completely unscrewing the positioning member 5. At the same time, this method requires less operating space height.

[0042] In order to facilitate the locating member 5 to enter the slot 107 laterally, a chamfer is provided at the corner between the slot 107 and the product facing surface 105 .

[0043] See Figure 4 or Figure 5 Since the upper side of the support plate nut standard part 4 is uneven, a groove 108 corresponding to the nut protrusion of the support plate nut standard part 4 can be provided on the lower side of the upper mounting part 102. The groove 108 extends through to the product facing surface 105. The groove 108 can position the nut protrusion without affecting the disassembly of the fixing block 1.

[0044] The fixing block 1 can be made of high-strength 30CrMnSi material, or a transparent block made of PC material. The transparent block makes it easy to check the relative positions of the hexagonal bolt 6 and the rivet 3.

[0045] See Figure 6 The positioning member 5 can be specifically a positioning bolt, the threaded portion of the positioning bolt is adapted to the threaded hole of the support plate nut standard part 4 and tightened to press the lower side mounting portion 103 and the product part 2 between the support plate nut standard part 4 and the bolt head of the positioning bolt.

[0046] See Figure 7 In the above embodiment, the hexagonal bolt 6 can be an inner hexagonal bolt with an inner hexagonal hole on its bolt head that is compatible with the inner hexagonal wrench 7. The hexagonal bolt 6 can also be an outer hexagonal bolt, which needs a corresponding outer hexagonal wrench to drive its rotation.

[0047] The specific usage of this pallet nut riveting tool is as follows:

[0048] 1. Place the support plate nut standard part 4 in the corresponding hole position of the product part 2, and screw the threaded part of the positioning part 5 into the threaded hole of the support plate nut standard part 4 for pre-fixation;

[0049] 2. Install rivet 3 into the processed rivet hole;

[0050] 3. Install the slot 107 of the fixing block 1 in correspondence with the positioning piece 5 and the standard support plate nut 4. Continue tightening the positioning piece 5 to secure the fixing block 1 and the standard support plate nut 4.

[0051] 4. Screw the hexagonal bolt 6 into the force threaded hole at the upper end of the fixing block 1 until it contacts the riveted end of the rivet 3;

[0052] 5. Apply pressure to the hexagonal bolt 6 using the hexagonal wrench 7 to deform and upset the riveted end of the rivet 3 to achieve the riveting effect;

[0053] 6. After loosening the positioning piece 5, pull out the hexagon socket bolt 6 and the fixing block 1 laterally, and then unscrew the positioning piece 5 from the support plate nut standard part 4 to complete the riveting.

[0054] Parts not described in detail in the above embodiments are prior art.

[0055] It should be noted that although the present invention has been described through the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and modifications to the present invention, and such changes and modifications shall fall within the scope of protection of the appended claims and their equivalents.
