[0005] Preferably, a collar is snapped onto the surface of the groove rod, and a positioning ruler is rotatably connected to the surface of the collar via a resistance shaft.

[0006] Preferably, each of the multiple lead screws has a slot on its surface, and an indicator block is fixedly connected to one end of each lead screw.

[0007] Preferably, a limiting piece is fixedly connected to the middle of the inner wall of the connecting box, and the limiting piece is inserted into the inside of the slot.

[0008] Preferably, the nut is threaded into the inside of the lead screw, and a acrylic plate is fixedly connected to the upper surface of the connecting box, with graduations on the surface of the acrylic plate.

[0009] This utility model provides a high-precision furnace bottom plate bolt hole positioning tool, which has the following advantages:

[0010] In use, the base plates can be arranged in a suitable configuration. Then, place the device in the middle of the base plate and turn the nut to make the base of the device in the middle of the base plate. Then, mark the holes on the base plate according to the triangle of the positioning ruler. Then, turn the positioning ruler to the appropriate angle mark according to the dial. This device improves the accuracy of the threaded hole position on the base plate and improves the installation quality. It avoids the problems of enlarged hole installation that seriously affect the installation quality, resulting in substandard quality, affecting the construction progress, and causing high project construction costs.

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a high-precision furnace bottom plate bolt hole positioning tool, including a base 1. Multiple lead screws 2 are welded to the surface of the base 1. Each lead screw 2 is fitted with a connecting box 3. A nut 4 is rotatably connected to one end of the connecting box 3. A support plate 5 is fixedly connected to the other end of the connecting box 3. A scale 6 is fixedly connected to the upper surface of the base 1. A grooved rod 7 is fixedly connected to the middle of the scale 6.

[0021] In use, rotating nut 4 can move connecting box 3, making it easier for the device to be positioned in the middle of the base plate, thus maintaining positioning accuracy.

[0022] A collar 8 is snapped onto the surface of the groove rod 7. A positioning ruler 9 is rotatably connected to the surface of the collar 8 via a resistance shaft. The positioning ruler 9 can be removed by removing the collar 8 from the groove rod 7.

[0023] Use the triangular part of the positioning ruler 9 to mark the corresponding position of the hole on the base plate. Then rotate the positioning ruler 9 and observe the scale 6 rotate to the accurate angle. Mark the hole again at the triangular part of the positioning ruler 9. Repeat this process to accurately mark and open the holes in 40 positions.

[0024] Each of the multiple lead screws 2 has a slot 10 on its surface. An indicator block 11 is fixedly connected to one end of the lead screw 2. A limiting piece 12 is fixedly connected to the middle of the inner wall of the connecting box 3. The limiting piece 12 is inserted into the slot 10. A nut 4 is threaded into the inside of the lead screw 2. An acrylic plate 13 is fixedly connected to the upper surface of the connecting box 3. The surface of the acrylic plate 13 is marked with scale.

[0025] The limiting piece 12 and the slot 10 keep the connecting box 3 in a horizontal position when moving, so that the support plate 5 can fit with the base plate, and the device is kept in the middle of the base plate according to the position of the indicator block 11 on the scale of the acrylic plate 13. This makes the subsequent hole fixing and hole opening positions more accurate, and also avoids the device from moving when fixing holes.

[0026] Specifically, when using this high-precision furnace bottom plate bolt hole positioning tool: The bottom plates to be used can be arranged in a suitable configuration. Then, the tool is placed in the center of the bottom plate, and the nut 4 is rotated so that the base 1 of the tool is located in the center of the bottom plate. Next, the positioning ruler 9 is used to mark the holes on the bottom plate according to the triangular point. Then, the positioning ruler 9 is rotated to the appropriate angle according to the scale 6. This tool improves the accuracy of the threaded hole position on the bottom plate and enhances the installation quality. It avoids the problems caused by enlarged holes, which can seriously affect the installation quality, leading to substandard quality, delayed construction, and high project construction costs.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
