[0002] In the construction of ultra-high voltage power transmission, grid connection of new energy power plants and smart grids, insulation equipment is required to have higher mechanical strength, and composite post insulators are developing towards larger diameter and larger tonnage.

[0003] In the production of composite post insulators, metal flanges and composite core rods need to be tightly connected through a press-fitting process. Traditional positioning fixtures are usually customized for a single flange specification. When a flange needs to be replaced, the entire positioning fixture needs to be replaced for different flange specifications. This results in long downtime for the entire production equipment, low changeover efficiency, and the need to redesign and manufacture new dedicated fixtures for each new flange type, leading to high production costs and occupying production space due to the coexistence of multiple fixtures.

[0023] Combination Figure 1-6 As shown, this utility model provides a positioning fixture 10 for the pressing process of composite post insulator flanges, used to connect the fixed base (not shown) of the pressing machine equipment and the flange 20. It includes: a transition plate 1, a transition block 2, and a positioning pin 3. The transition plate 1 is provided with a plurality of first mounting holes 11 and a plurality of positioning grooves 12. The first mounting holes 11 penetrate the transition plate 1 and are used to connect the fixed base. The plurality of positioning grooves 12 are evenly arranged on the transition plate 1. The transition block 2 is detachably installed in the positioning grooves 12. The transition block 2 is provided with positioning holes 21. One end of the positioning pin 3 is detachably connected to the positioning hole 21, and the other end is connected to the flange 20.

[0024] In this embodiment of the invention, the composite post insulator, as a key insulating component of the power system, directly affects the safety of power grid operation due to the accuracy of its flange press-fitting. The positioning fixture 10, connecting the fixed base and the flange 20, plays a comprehensive role in precise positioning, stable clamping, workpiece protection, and safety protection. The positioning fixture 10 connects the adapter plate 1 and the flange 20 via the adapter block 2 and the positioning pin 3. The flange 20 is connected to the core rod 30. Since the adapter block 2 and the adapter plate 1 are detachably connected, when replacing the flange 10, it is not necessary to replace the adapter plate 1; only the adapter block 2 and the matching positioning pin 3 need to be replaced to connect different flanges 20. This solves the problem in the production of existing composite post insulators where different specifications of flanges 20 require the replacement of the entire positioning fixture 10. Specifically, the fixed base is connected through the first mounting hole 11 on the adapter plate 1. The adapter block 2 is replaceably installed in the positioning groove 12 on the other side of the adapter plate 1 away from the fixed base, and the flange 20 is detachably connected through the positioning pin 3 passing through the positioning hole 21. This enables the positioning fixture 10 to press-fit and position different models of flanges 20.

[0025] In some embodiments, the positioning groove 12 extends outward from both sides to form mounting grooves 13, and the mounting grooves 13 are provided with second mounting holes 14. The two sides of the adapter block 2 extend outward from the mounting grooves 13 to form mounting portions 22, and the mounting portions 22 are provided with third mounting holes 23 corresponding to the second mounting holes 14.

[0026] In this embodiment, the positioning groove 12 and the mounting groove 13 form a cross-shaped groove. It can be understood that the positioning groove 12 penetrates the adapter plate 1, while the mounting groove 13 does not penetrate the adapter plate 1. The second mounting hole 14 is provided on the mounting groove 13. The adapter block 2 and the mounting part 22 form a cross-shaped block. The adapter block 2 corresponds to the positioning groove 12 and is detachably installed in the positioning groove 12. The third mounting hole 23 provided on the mounting part 22 corresponds to the second mounting hole 14, which helps the adapter block 2 to be connected to the adapter plate 1.

[0027] In some embodiments, the adapter plate 1 is in the shape of a circular plate, and the positioning groove 12 is in the shape of a long strip with one end of the positioning groove 12 pointing to the center of the adapter plate 1.

[0028] In this embodiment, the adapter plate 1 is in the shape of a round plate and corresponds to the fixed base of the press-fitting equipment, which helps to install the adapter plate 1 on the fixed base. The positioning groove 12 is in the shape of a long strip and one end of the positioning groove 12 points to the center of the adapter plate 1, which helps to distribute the positioning groove 12 evenly. After the adapter block 2 is detachably installed in the positioning groove 12, the positioning pin 3 can evenly connect the flange 20, so that the flange 20 is connected stably and positioned accurately.

[0029] In some embodiments, multiple positioning holes 21 are provided, and the multiple positioning holes 21 are evenly distributed from one end of the adapter block 2 to the other end of the adapter block 2.

[0030] In this embodiment, multiple positioning holes 21 are evenly distributed from one end of the adapter block 2 to the other end of the adapter block 2. That is, multiple positioning holes 21 on the adapter block 2 that are at the same distance from the center of the adapter plate 1 constitute a group of positioning holes 21. Multiple groups of different positioning holes 21 are used to connect flanges 20 of different sizes. Specifically, the diameter of the multiple positioning holes 21 gradually increases from one end of the adapter block 2 to the other end of the adapter block 2, which helps to connect different positioning pins 3, thereby connecting flanges 20 of different sizes.

[0031] In some embodiments, each first mounting hole 11 corresponds to a positioning groove 12 located at the other end of the positioning groove 12.

[0032] In this embodiment, the first mounting hole 11 is located at the other end of the positioning groove 12, which not only helps in the processing of the first mounting hole 11, but also makes the positioning pin 3 connected to the adapter plate 1 closer to the first mounting hole 11 when the first mounting hole 11 is connected to the fixed base of the press fitting machine, so that the positioning pin 3 is less likely to shake, thereby making the flange 20 connection stable.

[0033] In some embodiments, a plurality of threaded holes 15 are provided on the outer side of the adapter plate 1.

[0034] In this embodiment, when fixing the adapter plate 1 to the connecting column of the base, the lifting equipment (not shown) on the press machine needs to lift the adapter plate 1. The threaded hole 15 is used for lifting the adapter plate 1, which helps to quickly fix the adapter plate 1 to the connecting column of the base.

[0035] In some embodiments, the adapter plate 1 is provided with a clearance strip 16 extending from the edge to the center.

[0036] In this embodiment, after the adapter plate 1 is connected to the fixed base and the flange 20 is installed, when the lifting equipment on the press-fitting machine lifts the flange 20 to the adapter plate 1, the clearance strip 16 is used to avoid the lifting equipment, which helps to accurately position and install the flange 20.

[0037] In some embodiments, the positioning hole 21 is provided with a thread, and one end of the positioning pin 3 is threadedly connected to the positioning hole 21.

[0038] In this embodiment, the threaded connection makes the connection between the positioning pin 3 and the positioning hole 21 stable and detachable, which helps to cope with the installation of flanges 20 of different sizes.

[0039] In some embodiments, the positioning fixture 10 for the composite post insulator flange press-fitting process further includes: a first bolt 4, which is used to connect the first mounting hole 11 and the fixed base.

[0040] In this embodiment, the first bolt 4 is used to connect the first mounting hole 11 and the fixed base, which helps to make the connection between the adapter plate 1 and the fixed base stable and detachable, and facilitates maintenance and replacement.

[0041] In some embodiments, the positioning fixture 10 for the composite post insulator flange press-fitting process further includes a second bolt 5, which is used to connect the second mounting hole 14 and the third mounting hole 23.

[0042] In this embodiment, the second bolt 5 is used to connect the second mounting hole 14 and the third mounting hole 23, which helps to make the connection between the adapter plate 1 and the adapter block 2 stable and detachable, and facilitates maintenance and replacement.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
