[0002] At present, the assembly between some long shaft type workpieces and substrates in press riveting processing and treatment exists the problem of non-ideal processing precision. This is mainly because the long shaft type workpiece is long in length, and is prone to stress deviation when press riveting with the substrate, thereby causing the workpiece and the substrate to be offset, and the contact point of the workpiece and the substrate deviates from the design area after press riveting, thereby causing the workpiece and the substrate to be unable to achieve the designed perpendicularity after press riveting processing. SUMMARY
[0003] In order to solve the problem of the workpiece and the substrate being unable to achieve the designed perpendicularity after press riveting processing in the background art, the utility model provides the following technical scheme:

[0005] Among them, the limiting portion and the positioning portion are coaxially connected, and the diameter of the limiting portion is smaller than the diameter of the positioning portion.
[0006] Further, on the axial section of the limiting portion and the positioning portion, the width of the limiting cavity is smaller than the width of the positioning groove.
[0007] Further, the axial direction of the limiting cavity is perpendicular to the radial direction of the positioning groove.
[0008] Further, the width of the positioning portion is greater than the length of the positioning portion.
[0009] Further, the diameter of the limiting cavity matches the press riveting piece, and the diameter of the positioning groove matches the substrate.

[0012] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.
[0013] It should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present patent and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present patent.
[0014] Figure 1 It is a schematic diagram of the shaft section structure of the press-in jig according to the embodiment of the present application.
[0015] Referring to Figure 1 , the press-in jig according to the embodiment of the present application comprises a limiting part 1 and a positioning part 2. The limiting part 1 is internally provided with a limiting cavity 11 for limiting a press-in part 3. The shape and size of the limiting cavity 11 are matched with the press-in part 3 to ensure that the press-in part 3 can maintain the correct position and posture during the press-in process, avoiding deviation or shaking, thereby ensuring the press-in quality. One end of the positioning part 2 is recessed to form a positioning groove 21 for limiting a base plate, and the other end of the positioning part 2 is fixedly connected with the limiting part 1 perpendicularly to form an integral structure. When performing press-in processing, the jig fixes the outer peripheral surface of the positioning part 2, the press-in part 3 abuts against the surface of the base plate through the limiting cavity 11, and after the presser is lowered, the press-in part 3 is naturally combined with the base plate to form an integrated structure.
[0016] Specifically, the positioning groove 21 and the limiting cavity 11 in the limiting part 1 are in communication with each other, so that the press-in part 3 and the base plate can be cooperatively positioned in the jig, thereby further improving the accuracy and reliability of the press-in operation. Among them, the limiting part 1 and the positioning part 2 are coaxially connected in space position, thereby ensuring the balance and symmetry of the entire jig during use, so that the pressure applied on the press-in part 3 and the base plate can be uniformly distributed. At the same time, the diameter of the limiting part 1 is smaller than the diameter of the positioning part 2, which not only meets the positioning needs of different parts, but also forms a reasonable nesting relationship on the overall structure, so that the structure of the entire jig is more compact and stable.
[0017] Further, on the axial section of the positioning part 2, the axis direction of the limiting cavity 11 is perpendicular to the radial direction of the positioning groove 21, and the width of the limiting cavity 11 is smaller than the width of the positioning groove 21, and the length of the limiting part 1 is greater than the length of the positioning part 2, so as to ensure that the riveting piece 3 and the base plate always maintain the perpendicular state during the riveting process. Through the setting of the spatial position relationship, the positioning function of the jig is further optimized, so that the riveting piece 3 and the base plate can realize accurate alignment and positioning in the vertical direction, and a more accurate spatial positioning reference is provided for the riveting process.
[0018] In summary, the vertical state of the riveting piece is stabilized by the limiting part, and the base plate is limited and fixed by the positioning part, so that the riveting piece always maintains the perpendicular state with the base plate after being stressed during the riveting process.
