[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0028] In related technologies, the traditional riveting process for the inner flange of a high-voltage switch housing involves manually marking and aligning lines, using manual support for positioning, and finally riveting. This riveting method makes it difficult to guarantee the positional accuracy and parallelism of the holes in the inner flange.

[0029] This embodiment provides a riveting fixture for the inner flange of a high-voltage switch housing to improve the accuracy of the riveting position of the inner flange.

[0030] Please see Figures 1-3In this embodiment, a high-voltage switch housing inner cavity flange riveting fixture includes a cylinder 10, an adjusting rod 20, and an inner support plate 30; the top of the cylinder 10 is provided with a connecting flange 11, the side wall of the cylinder 10 is provided with a slot 14, and a limiting rod 16 is provided in the slot 14; the adjusting rod 20 is screwed onto the axis of the cylinder 10, and a connecting plate 21 is rotatably connected to the adjusting rod 20; the inner support plate 30 is slidably engaged with the limiting rod 16, and the inner end of the inner support plate 30 is hinged to the connecting plate 21.

[0031] By adopting the technical solution of this embodiment, the inner support plates 30 are simultaneously oscillating around the limiting rod 16 by rotating the adjusting rod 20, so as to support and fix the inner cavity flange inside. The riveting position of the inner cavity flange is fixed as the connecting flange 11 is connected to the outer flange of the high voltage switch housing, thereby improving the accuracy of the riveting position of the inner cavity flange.

[0032] In this embodiment, the cylinder 10 is constructed in a cylindrical shape, and the connecting flange 11 is fixedly connected to the top end of the cylinder 10. The connecting flange 11 and the cylinder 10 are arranged coaxially. A sleeve 13 for connecting with the adjusting rod 20 is provided at the axis of the cylinder 10. A plurality of connecting plates 12 are fixedly connected between the sleeve 13 and the connecting flange 11. The connecting plates 12 are arranged radially along the cylinder 10, and the plurality of connecting plates 12 are evenly distributed circumferentially along the cylinder 10, so that the sleeve 13 and the connecting flange 11 are arranged coaxially.

[0033] In addition, the slot 14 extends axially upward from the bottom end of the cylinder 10 and is evenly distributed around the circumference of the cylinder 10. At the same time, a mounting groove 15 for accommodating the limiting rod 16 is provided on the bottom end face of the cylinder 10. The mounting groove 15 is constructed as an annular shape coaxial with the cylinder 10, and the limiting rod 16 is constructed as a circle coaxial with the cylinder 10. The limiting rod 16 is snapped into the inside of the mounting groove 15. In order to improve the stability of the installation, the limiting rod 16 can be fixed by adhesive or welding inside the mounting groove 15.

[0034] In this embodiment, the adjusting rod 20 is screwed inside the sleeve 13, and the adjusting rod 20 is coaxially arranged with the cylinder 10. A connecting plate 21 is rotatably connected to the lower end of the adjusting rod 20. The connecting plate 21 is used to hinge with multiple inner support plates 30.

[0035] In this embodiment, the inner support plate 30 is snapped into the slot 14. Along the longitudinal direction of the inner support plate 30, a sliding groove 31 is provided on the inner support plate 30. The sliding groove 31 and the limiting rod 16 located inside the slot 14 form a sliding engagement. The inner support plate 30 can rotate around the limiting rod 16. The inner end of the inner support plate 30 is hinged to the connecting plate 21, and the inner end of the inner support plate 30 is higher than its outer end.

[0036] It should be noted that when the adjusting rod 20 is rotated toward the inside of the cylinder 10, it will cause the inner end of the inner support plate 30 to move downward. At this time, the outer end of the inner support plate 30 will tilt upward as it moves outward.

[0037] In use, first, fit the inner flange onto the outside of the cylinder 10, then screw the adjusting rod 20 toward the inside of the cylinder 10. The outer ends of each inner support plate 30 will move outward and tilt upward. Each inner support plate 30 will support and fix the inner flange from the inside. Then, place the fixture inside the high-voltage switch housing and fix the connecting flange 11 to the outer flange of the high-voltage switch housing with bolts. Finally, the inner flange can be welded.

[0038] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
