Detailed Implementation

[0021] This utility model provides a positioning device for the iron core insert of a drainage pump.

[0022] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a platform 1, a track groove 2 arranged in a circular array on the top of the platform 1, a sliding member 3 slidably connected in the track groove 2, a positioning rod 4 on the top of the sliding member 3, a cylinder 5 installed at the bottom of the platform 1, a lifting plate 6 fixedly connected to the piston rod end at the bottom of the cylinder 5, and an inclined rod 7 rotatably connected between the lifting plate 6 and the sliding member 3. Specifically, the cylinder model 5 is not limited, and the appropriate equipment will be used.

[0023] Please see Figure 2 and Figure 3The sliding component 3 includes a track plate 31 that is slidably connected to the inside of the track groove 2. An adjustment groove 32 is provided at the bottom of the track plate 31. An adjustment plate 33 is slidably connected in the adjustment groove 32. The adjustment plate 33 is rotatably connected to one end of the tilting rod 7. Through-holes are provided on the inner walls of both sides of the adjustment groove 32. Rotating rods 34 are rotatably connected in the rotating holes. A bolt is fixedly connected to one end of the rotating rod 34 located on the adjustment plate 33. Threaded grooves are provided on both sides of the adjustment plate 33. The bolts are threadedly connected to the threaded grooves. Specifically, when the position of a positioning rod 4 deviates, two rotating rods 34 can be turned simultaneously, causing one rotating rod 34 to push the adjusting plate 33 to slide within the adjusting groove 32, while the other rotating rod 34 pulls the adjusting plate 33 to slide within the adjusting groove 32. This facilitates the adjustment of the position of a single track plate 31 and the corresponding positioning rod 4. After the position of the adjusting plate 33 is adjusted, one or more rotating rods 34 can be turned to improve the stability of the position adjustment of the adjusting plate 33. A corrugated telescopic cover can be fitted over the bolt to cover it, thereby improving the dustproof effect of the bolt. Since the corrugated telescopic cover is an existing technology structure, it will not be described in detail in this application.

[0024] Please see Figure 1 and Figure 2 The bottom of the platform 1 is fixedly connected to four support rods 9 arranged in a circular array, and a connecting base plate 10 is fixedly connected between the four support rods 9.

[0025] Please see Figure 1 and Figure 2 The top of the connecting base plate 10 and the bottom of the platform 1 are both fixedly connected with guide rods 11 arranged in a circular array. The lifting plate 6 has a through guide hole at the corresponding position of each guide rod 11, and the guide rod 11 is slidably set inside the corresponding guide hole.

[0026] Please see Figure 4 The bottom end of the positioning rod 4 is fixedly connected to the screw rod 8, and the top of the track plate 31 is provided with a threaded groove that is threadedly connected to the screw rod 8. Specifically, the screw 8 is connected to the threaded groove by a threaded connection, which facilitates the disassembly and assembly of the positioning rod 4 and allows for the installation of the positioning rod 4 of the required size.

[0027] Please see Figure 4 The bottom of the positioning rod 4 is provided with an I-shaped groove 12, and an I-shaped plate is adapted in the I-shaped groove 12. A triangular support plate 13 is fixedly connected to one side of the I-shaped plate, and the bottom of the triangular support plate 13 is in contact with the top of the track plate 31. Specifically, if the iron core insert has no opening, multiple positioning rods 4 are used to clamp and contact the outer wall of the iron core insert from the outside to achieve outer wall positioning. Triangular support plates 13 can be assembled onto the positioning rods 4 to support the positioning rods 4, thereby improving the stability of the positioning rods 4 and preventing the positioning rods 4 from tilting and deforming due to extrusion pressure. The positioning rods 4 can be provided with I-shaped grooves 12 according to actual needs. When the positioning rods 4 are small, the design of I-shaped grooves 12 and triangular support plates 13 is omitted.

[0028] Please see Figure 1 and Figure 2 Line rods are fixedly connected to the inner walls on both sides of the track groove 2, and line grooves are opened on the inner walls on both sides of the track plate 31, with the line rods slidably connected to the corresponding line grooves.

[0029] Please see Figure 1 and Figure 2 A placement box 14 is installed on the top of the connecting base plate 10; Specifically, the placement box 14 can hold spare or unused positioning rods 4 and triangular support plates 13.

[0030] Working principle: In the initial state, based on the structural characteristics of the iron core insert to be positioned, such as whether it has positioning holes and its external dimensions, the required number and position of positioning rods 4 are determined; by adjusting the position of the sliding member 3 in the track groove 2, the positioning rods 4 are moved to the predetermined position. If the iron core insert has a positioning hole, then align the positioning rod 4 and insert it into the hole to achieve hole positioning; If the core insert has no opening, multiple positioning rods 4 are used to clamp and contact the outer wall of the core insert from the outside to achieve outer wall positioning; During the adjustment process, the position of each sliding component 3 can be controlled individually, thereby independently adjusting the radial and angular positions of each positioning rod 4 to ensure precise fit with the iron core insert.

[0031] The specific structural driver is as follows: When the cylinder 5 is activated, its piston rod drives the lifting plate 6 to move up and down. The lifting plate 6 pulls or pushes the sliding part 3 along the track groove 2 through the tilting rod 7, thereby driving the positioning rod 4 to move radially. The guide rod 11 cooperates with the guide hole to ensure that the lifting plate 6 moves smoothly and improves the overall adjustment accuracy.

[0032] After positioning is completed, the iron core insert is stably fixed by multiple positioning rods 4, and subsequent insert, winding or assembly processes can be carried out.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
