[0002] Press riveting is a riveting process that uses pressure to deform rivets and connect components. It offers excellent consistency and stability and is widely used in mechanical manufacturing. However, during press riveting, the workpiece material can sometimes be damaged due to its thinness, such as when riveting double-layer thin plates.

[0003] Directly riveting double-layer thin plate workpieces during assembly not only results in a gap between the thin plate workpieces exceeding 0.1mm, but also causes severe misalignment between the center of the rivet and the center of the hole after riveting, and may even cause deformation of the workpiece, which greatly affects product quality. Utility Model Content

This thin-plate anti-deformation riveting fixture is specifically designed for thin-plate riveting. This solution uses the upper and lower plates of the fixture to position and fix the double-layer thin-plate workpiece, preventing the workpiece from shifting during the riveting process, thus avoiding the problem of the gap between the workpieces after riveting being greater than 0.1mm. It also avoids serious misalignment between the center of the rivet and the center of the hole after riveting, and prevents workpiece deformation.

[0006] This application provides a thin plate anti-deformation riveting fixture for riveting double-layer thin plate workpieces, including a fixture upper plate located above the double-layer thin plate workpiece and a fixture lower plate located below the double-layer thin plate workpiece; the fixture upper plate is provided with positioning holes, fixing holes and riveting holes, and the fixture lower plate is provided with positioning blocks, threaded holes and predetermined holes.

[0009] In a further improvement of this utility model, the fixing hole adopts an elongated hole structure, and fixing holes are respectively opened at the left and right ends of the upper plate of the tooling.

[0010] In a further improvement of this utility model, a riveting head is provided in the riveting hole, and the riveting head passes through the riveting hole and abuts against the rivet on the double-layer thin plate workpiece.

[0011] In a further improvement of this utility model, the predetermined hole corresponds to the rivet position on the double-layer thin plate workpiece.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0028] During the riveting process, the workpiece material is sometimes prone to damage due to its thinness, such as when riveting double-layer thin plate workpieces. Directly riveting double-layer thin plate workpieces during assembly will not only cause the gap between the thin plate workpieces to be greater than 0.1mm, but also result in serious misalignment between the center of the rivet and the center of the hole after riveting, and may even cause deformation of the workpiece, which will greatly affect the product quality.

[0029] Therefore, the design concept of this application is to design a tooling for positioning and fixing double-layer thin plate workpieces, to prevent the workpieces from shifting during the riveting process, which would result in a gap greater than 0.1mm after riveting, to prevent serious misalignment between the center of the rivet and the center of the hole after riveting, and to prevent workpiece deformation.

[0030] like Figure 1-4 As shown, this application provides a thin plate anti-deformation riveting fixture for riveting assistance of a double-layer thin plate workpiece 3, including a fixture upper plate 1 located above the double-layer thin plate workpiece 3 and a fixture lower plate 2 located below the double-layer thin plate workpiece 3; the fixture upper plate 1 is provided with positioning holes 11, fixing holes 12 and riveting holes 13, and the fixture lower plate 2 is provided with positioning blocks 21, threaded holes 22 and predetermined holes 23.

[0031] The positioning hole 11 is connected to a positioning pin 111, which passes through the positioning hole 11 and abuts against the upper surface of the double-layer thin plate workpiece 3, thereby positioning the upper thin plate workpiece of the double-layer thin plate workpiece 3.

[0032] The fixing hole 12 is connected to a bolt 121, which is threadedly connected to the threaded hole 22 to fix the upper plate 1 and the lower plate 2 of the fixture.

[0033] The fixing hole 12 adopts an open elongated hole structure. Fixing holes 12 are respectively opened at the left and right ends of the tooling plate 1. The open elongated hole structure makes it easier for the bolt 121 to pass through and facilitates the connection with the threaded hole 22.

[0034] A riveting head 131 is slidably disposed in the riveting hole 13. The riveting head 131 passes through the riveting hole 13 and abuts against the rivet 32 ​​on the double-layer thin plate workpiece 3. When in use, the press machine is started and the press machine presses down the riveting head 131, and the riveting head 131 presses the rivet 32.

[0035] The predetermined hole 23 corresponds to the position of the rivet 32 ​​on the double-layer thin plate workpiece 3. In use, the double-layer thin plate workpiece 3 is placed according to the position of the predetermined hole 23, wherein the predetermined hole 23 corresponds to the position of the rivet 32, that is, the rivet 32 ​​is placed above the predetermined hole 23.

[0036] Wherein, the height of the positioning block 21 is less than or equal to the thickness of the lower thin plate workpiece of the double-layer thin plate workpiece 3. In actual use, the workpiece size of the double-layer thin plate workpiece 3 may not be equal. Therefore, through the above design, interference between the positioning block 21 and the upper thin plate workpiece of the double-layer thin plate workpiece 3 is avoided. There are four positioning blocks 21, and the positioning space is between the four positioning blocks 21. The lower thin plate workpiece of the double-layer thin plate workpiece 3 is placed in the positioning space. The four positioning blocks 21 are arranged with one on each of the four sides. After the double-layer thin plate workpiece 3 is placed, the four positioning blocks 21 are located on the four sides of the lower thin plate workpiece and abut against each other to achieve the purpose of positioning the lower thin plate workpiece.

[0037] The application of this method involves placing a double-layer thin plate workpiece 3 (with rivets 32 already inserted) on the corresponding position of the lower plate 2 of the tooling (wherein, the lower thin plate workpiece of the double-layer thin plate workpiece 3 is placed in the positioning space, and the position of the rivet 32 ​​on the double-layer thin plate workpiece 3 corresponds to the predetermined hole 23); thus, the positioning space achieves the function of positioning the lower thin plate workpiece of the double-layer thin plate workpiece 3, and the rivet 32 ​​passes through and limits the double-layer thin plate workpiece 3. This double positioning prevents the workpiece from shifting during the riveting process, which would lead to the problem of the gap between the two parts being greater than 0.1mm after riveting and the problem of workpiece deformation; The upper tooling plate 1 is placed on the double-layer thin plate workpiece 3. The positioning pin 111 passes through the positioning hole 11 and abuts against the upper surface of the double-layer thin plate workpiece 3. The bolt 121 passes through the fixing hole 12 and is threadedly connected to the threaded hole 22. The upper tooling plate 1 and the lower tooling plate 2 are connected. In this way, the upper tooling plate 1 (positioning pin 111) positions the upper thin plate workpiece of the double-layer thin plate workpiece 3, and the upper tooling plate 1 and the lower tooling plate 2 are connected to press and fix the double-layer thin plate workpiece 3. This double positioning prevents the riveting assembly from shifting during the riveting process, and avoids serious misalignment between the center of the rivet 32 ​​and the center of the rivet hole 31 and workpiece deformation after riveting. The press-fit head 131 is passed through the press-fit hole 13 and abuts against the rivet 32 ​​on the double-layer thin plate workpiece 3. The press-fit machine is started, and the press-fit machine presses down the press-fit head 131 to press-fit the rivet 32 ​​(the pressure of the press-fit machine is 10KN, which is more conducive to ensuring that the diameter of the rivet head after press-fitting is greater than 9mm, which meets the production standard).
