[0027] Reference Figure 1 As shown, this application provides a press-fit fixture, including:

[0028] Press-fit component 1, the press-fit component 1 is provided with a working surface 11, and the working surface 11 is provided with a pre-installation position 111;

[0029] The end side of the press-fit part 1 extends in a direction perpendicular to the working surface to form a connecting part 12, and the end side of the connecting part 12 away from the press-fit part 1 bends toward the location of the pre-installation position 111 to form a bending part 121.

[0030] The fixing member 2, which abuts against the pressing part 1, has a pressing surface 21 and a positioning hole 22 is provided on the side wall of the fixing member 2 adjacent to the pressing surface 21.

[0031] The bent portion 121 passes through the positioning hole 22; the pressing surface 21 is recessed in the direction away from the pressing part to form a positioning groove 211, which is used to accommodate the fastener. The working surface 11 abuts against the pressing surface 21, and the positioning groove 211 corresponds to the pre-installation position 11, which is used to press the fastener onto the pre-installation position 111.

[0032] according to Figure 1 Those skilled in the art can configure the press-fitting part 1 and the fixing part 2 to cooperate, so that fasteners can be installed on the press-fitting part 1.

[0033] Specifically, in the above configuration, the end side of the press-fitting component 1 extends in a direction perpendicular to the working surface 11 to form a connecting portion 12. The end side of the connecting portion 12 away from the press-fitting component 1 is bent toward the location of the pre-installation position 111 to form a bent portion 121.

[0034] In the above structure, the bent portion 121 formed by bending the end of the connecting portion 121 on the press-fit part 1 extends toward the location of the pre-installation position 111 and remains separated from the pre-installation position 111.

[0035] It is understandable that the bend 121 extends toward the location of the pre-installation position 111, which causes interference at the pre-installation position 111 on the working surface 11 of the press-fit 1 during fastener installation.

[0036] During the actual installation process, when the aforementioned press-fit component 1 is used for fastener installation, the fastener is installed from the location of the bent portion 121 towards the location of the pre-installation position 111. In the above structure, the location of the bent portion 121 is in the fastener installation direction, which can cause difficulties in fastener installation.

[0037] In a further configuration, those skilled in the art can provide a fixing member 2, wherein the fixing member 2 is provided with a pressing surface 21, and the pressing surface 21 abuts against the working surface 11.

[0038] Based on the above structure, those skilled in the art can also provide a positioning hole 22 on the fixing member 2. In the structure where the pressing surface 21 abuts against the working surface 11, the bent portion 121 passes through the positioning hole 22.

[0039] With the above structure, those skilled in the art can further provide a positioning groove 211 at the position of the pressing surface. Specifically, the positioning groove 211 is recessed in a direction away from the position of the pressing part 1, and the positioning groove 211 corresponds to the pre-installation position 111.

[0040] Based on the structure corresponding to the positioning groove 211 and the pre-installation position 111, during the specific pressing process, those skilled in the art first place the fastener in the positioning groove 211, and then install the pressing part 1 onto the fixing part 2. In the aforementioned process, the bent portion 121 on the pressing part 1 passes through the positioning hole 22, and the working surface 11 abuts against the pressing surface 21. Furthermore, those skilled in the art can continue to press the working surface 11 against the pressing surface 21, thereby pressing the fastener in the positioning groove 211 onto the pre-installation position 111 of the working surface 11.

[0041] Based on the above structure and process, the press-fit part 1 with the bent portion 121 can be stably press-fitted. It is worth noting that in the actual production process, the press-fit parts 1 with the bent portion 121 produced in batches can be continuously and stably press-fitted by the fixing part 2.

[0042] In summary, by providing positioning holes 22 and positioning grooves 211 on the fastener 2, multiple press-fitting parts 1 with bending portions 121 can be continuously and stably press-fitted, thereby greatly improving the efficiency of fastener pressing of the press-fitting parts 1.

[0043] In the above embodiments, those skilled in the art would configure the bent portion 121 formed by bending the end of the connecting portion 121 on the press-fit component 1 to extend toward the location of the pre-installation position 111. Preferably, the connection between the bent portion 121 and the connecting portion 12 of the press-fit component 1 is an arc-shaped surface.

[0044] With the above structure, an arc-shaped surface is provided at the connection position between the bending part 121 and the connecting part 12, so that the stress distribution transmitted to the connection position between the bending part 121 and the connecting part 12 during the pressing process of the press-fitting part 1 is more reasonable, thereby avoiding stress concentration and deformation and fracture.

[0045] In an optional embodiment, preferably, the minimum distance from the bent portion 121 to the press-fit member 1 is equal to the minimum distance from the positioning hole 22 to the press-fit member 1. That is, the minimum distance at which the press-fit member 1 is placed on the bent portion 121 towards the press-fit member 1 is the minimum height of the bent portion 121 from the press-fit member 1. The minimum distance from the positioning hole 22 to the press-fit member 1 is equal to the minimum height of the bent portion 121 from the press-fit member 1, so that the bent portion 121 and the positioning hole 22 can be stably engaged during the process of placing the press-fit member 1 onto the fixing member 2.

[0046] With the above structure, the minimum distance between the bent portion 121 and the press-fitting part 1 is equal to the minimum distance between the positioning hole 22 and the press-fitting part 1 as set by those skilled in the art. During the press-fitting process of the press-fitting part 1, the relative position between the bent portion 121 and the fixing part 2 can remain stable, thereby preventing other parts of the press-fitting part 1 from being squeezed and deformed during the press-fitting process.

[0047] More preferably, the bent portion 121 contacts the inner wall of the positioning hole 22, thereby effectively keeping the through-hole structure of the bent portion 121 and the positioning hole 22 stable.

[0048] In an optional embodiment, preferably, both ends of the inner wall of the positioning hole 22 are provided as arc-shaped surfaces. In the above embodiment, the bent portion 121 contacts the inner wall of the positioning hole 22, and the fact that both ends of the inner wall of the positioning hole 22 are provided as arc-shaped surfaces can prevent stress concentration at the contact points between the bent portion 121 and the two ends of the inner wall of the positioning hole 22, thereby improving the structural reliability of the fastener 2.

[0049] In the installation structure, preferably, a mounting hole is provided at the pre-installation position 111 on the working surface 11, and the inner diameter of the mounting hole is smaller than the inner diameter of the positioning groove 211. In this embodiment, the fastener is installed into the mounting hole at the pre-installation position 111 by press-fitting. Specifically, the inner diameter of the mounting hole is smaller than the inner diameter of the positioning groove 211, which makes the installation process of the fastener more stable and prevents the fastener from shifting position after installation.

[0050] In the above embodiments, preferably, the fastener is a nut. That is, the nut is placed in the mounting groove 211 and installed into the mounting hole by press-fitting, thereby completing the press-fitting of the fastener.

[0051] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Slightly modified implementations based on certain industry standards or custom methods or embodiments can also achieve the same, equivalent, or similar, or predictable, implementation effects as the above embodiments. Embodiments applying these modified or modified data acquisition, processing, output, and judgment methods still fall within the scope of optional implementations of this application.

[0052] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
