[0027] like Figures 1 to 4As shown, an embodiment of this utility model provides a mounting sleeve riveting fixture, including a base 1, a riveting plate 2, and a riveting mechanism. The base 1 is provided with a mounting groove 3, which includes a first positioning groove 4 and a second positioning groove 6. The first positioning groove 4 has a first opening 5 that penetrates the top surface of the base 1. The second positioning groove 6 is formed by the downward indentation of the bottom wall of the first positioning groove 4. The second positioning groove 6 has a second opening 7 facing the first opening 5. The first positioning groove 4 and the second positioning groove 6 are connected through the second opening 7. The area of ​​the second opening 7 is smaller than the area of ​​the first opening 5. The second positioning groove 6 is suitable for the housing of a charging socket to be installed, and the first positioning groove 4 is suitable for the mounting ring 9 of the charging socket to be installed.

[0028] The rivet plate 2 is located above the base 1. The rivet mechanism can drive the rivet plate 2 to move closer to the base 1 so as to press the mounting sleeve of the charging socket into the mounting ring 9 of the charging socket.

[0029] In this embodiment, the charging socket is installed in the mounting groove 3, so that the housing of the charging socket is installed in the second positioning groove 6 through the second opening 7, and the mounting ring 9 of the charging socket is installed in the first positioning groove 4 through the first opening 5. The bottom surface of the mounting ring 9 is placed on the bottom wall of the first positioning groove 4. The riveting mechanism drives the riveting plate 2 to move towards the base 1, so that the riveting plate 2 rivets the mounting sleeve into the mounting ring 9. Compared with the prior art, the operation is simple, saves labor, and improves the riveting efficiency.

[0030] In this embodiment, the ability of the rivet plate 2 to move toward the base 1 means that the rivet plate 2 can be driven by a driving mechanism to passively move toward the base 1.

[0031] In this embodiment, the driving mechanism is a lifting cylinder, which is existing technology and will not be described in detail here.

[0032] In this embodiment, when using the installation sleeve riveting fixture, the base 1 can be fixed on a workbench, a mounting bracket can be fixed on the workbench, a lifting cylinder can be fixed on the mounting bracket, and the riveting plate 2 can be connected to the lifting cylinder so that the riveting plate 2 is located directly above the base 1. During riveting, the lifting cylinder drives the riveting plate 2 to descend.

[0033] In one embodiment, a guide assembly 11 is also included. The guide assembly 11 includes a guide rod 12. A pressing hole 8 is provided on the bottom wall of the first positioning groove 4. The guide rod 12 is slidably assembled in the pressing hole 8 in the up-down direction. The top end of the guide rod 12 has a bearing portion, which is suitable for the installation sleeve of the charging socket.

[0034] In this embodiment, the guide rod 12 is slidably mounted in the pressing hole 8 in the vertical direction.

[0035] In this embodiment, the outer diameter of the bearing portion of the guide rod 12 is adapted to the inner diameter of the mounting sleeve. When the mounting sleeve is fitted onto the bearing portion, the mounting sleeve will not slide down on its own due to the friction between the outer peripheral surface of the bearing portion and the inner wall surface of the mounting sleeve.

[0036] In this embodiment, during riveting, the riveting plate 2 first contacts the mounting sleeve as it descends. The static friction between the mounting sleeve and the bearing portion drives the mounting sleeve and guide rod 12 to descend together, at which point the mounting sleeve remains stationary relative to the guide rod 12. When the guide rod 12 reaches its lowest position and stops descending, the riveting plate 2 continues to descend. At this point, the riveting plate 2 drives the mounting sleeve to descend relative to the guide rod 12, pressing it into the mounting hole of the mounting ring platform 9 under the guidance of the guide rod 12.

[0037] In this embodiment, the guide rod 12 is provided so that the mounting sleeve will not tilt during descent, thereby improving the stability of the mounting sleeve during descent.

[0038] In one embodiment, the guide rod 12 includes a large diameter section 14 and a small diameter section, the small diameter section is located above the large diameter section, the outer peripheral surface of the large diameter section 14 contacts the inner wall of the pressing hole 8, and the top end of the small diameter section 13 is provided with a bearing portion.

[0039] In this embodiment, the outer peripheral surface of the large-diameter section 14 contacts the inner wall of the pressing hole 8, so that the pressing hole 8 can guide the large-diameter section 14 and improve the stability of the guide rod 12 when it moves.

[0040] In one embodiment, a positioning ring platform is provided on the inner wall of the pressing hole 8, and a through hole 10 is provided on the positioning ring platform. The outer peripheral surface of the small diameter section 13 is in contact with the inner wall of the through hole 10.

[0041] In this embodiment, the upper surface of the positioning ring platform and the inner wall of the pressing hole 8 form an upward-opening receiving groove. The setting of the receiving groove increases the stroke of the mounting sleeve as it descends, so as to ensure that the mounting sleeve can be completely pressed into the mounting hole.

[0042] In this embodiment, the inner wall surface of the perforation 10 contacts the outer peripheral surface of the small diameter section 13, which guides the small diameter section 13 and further improves the stability of the guide rod 12.

[0043] In one embodiment, the guide assembly 11 further includes an elastic element 15, the pressing hole 8 is a blind hole with an upward opening, the bottom end of the elastic element 15 is connected to the bottom wall of the pressing hole 8, and the top end of the elastic element 15 is connected to the bottom surface of the guide rod 12.
