[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-9As shown, this utility model provides a technical solution: a dimensional measuring device for an outer diameter machine tool, including a base 1. The base 1 has a strip-shaped through groove and a sliding hole 2 on one side. A threaded hole 3 is provided through one side of the sliding hole 2. A column 4 is slidably connected inside the sliding hole 2. A hinge block 5 is slidably connected to the column 4. A connecting block 9 is rotatably connected to the hinge block 5. An internally threaded conical nest 10 is connected to the connecting block 9. A sliding hole 3 11 is provided on the connecting block 9. A threaded hole 2 12 is provided through one side of the sliding hole 3 11. A column 2 13 is slidably connected inside the sliding hole 3 11. A connecting block 2 14 is slidably connected to the column 2 13. A limit block 15 is slidably connected to one end of the column 2 13. A limit block 15 is provided on one side. A connecting hole 28 is provided, and an adjustment hole 29 is provided on the limiting block 15. The second column 13 is slidably engaged with the connecting hole 28. A threaded hole 30 is provided through one side of both the connecting hole 28 and the adjustment hole 29, and a screw is threaded into the threaded hole 30. A positioning column 31 is slidably connected in the adjustment hole 29. The positioning column 31 abuts against the measuring rod 20. By loosening the screw on one side of the adjustment hole 29, the positioning column 31 can slide in the adjustment hole 29. Thus, when the screws on the connecting block 24 and the hinge block 29 are loosened, the positioning column 31 can be moved to push the measuring rod 20 to move, thereby using the positioning column 31 to make small-area fine adjustments to the height and angle of the measuring rod 20 within a certain range.

[0014] An adjusting block 16 is slidably connected to the second column 13. The adjusting block 16 has a through hole 24, and a threaded hole 25 is provided through one side of the through hole 24. The second column 13 slides in the through hole 24. A screw is threaded in the threaded hole 25. By loosening the screw in the threaded hole 25, the adjusting block 16 can slide on the second column 13, thereby changing the position of the adjusting block 16 to meet the usage requirements.

[0015] A spring 17 is connected to the adjusting block 16. One end of the spring 17 is connected to the adjusting block 28. The adjusting block 28 has a through hole 26. A threaded hole 5 27 is provided through one side of the through hole 26. The adjusting block 28 slides on the measuring rod 20 through the through hole 26. A screw is threaded into the threaded hole 5 27. By loosening the screw at the threaded hole 5 27, the adjusting block 28 can slide on the measuring rod 20. When the displacement of the adjusting block 16, the adjusting block 28, or the measuring rod 20 changes, the spring 17 will be stretched. The rebound of the spring 17 allows the measuring rod 20 to slide on the hinge block 29. This keeps one end of the instrument clamp 21 of the measuring rod 20 always on the L-shaped groove side of the limit block 15, thus keeping the measuring instrument away from the workpiece and preventing interference with normal loading and unloading.

[0016] A hinge block 19 is rotatably connected to the connecting block 2 14. Both hinge block 1 5 and hinge block 2 19 have grooves 6 on one side, conical grooves 7, and sliding holes 2 8. The column 1 4 slides within the sliding hole 2 8. A threaded hole 3 22 is provided through one side of the sliding hole 2 8. An internally threaded conical nest 10 is inserted into the conical groove 7, with a threaded hole at one end. The threaded hole 3 22 and the internally threaded conical nest 10... All 10 are threaded with screws. The tapered groove 7 is connected to the groove 6 and the groove 6 is fitted with a washer 23. The internal thread tapered nest 10 is inserted into the tapered groove 7, so that the connecting block 1 9 and the hinge block 1 5 or the connecting block 2 14 and the hinge block 2 19 can rotate relative to each other, thereby adjusting the working angle of the column 2 13 and the measuring rod 20. The operation is simple and convenient. When the screw is tightened, the washer 23 will fit with the groove 6 to press and fix it to prevent accidental rotation.

[0017] The second hinge block 19 is slidably connected to the measuring rod 20 through the second sliding hole 8. One end of the measuring rod 20 is connected to the instrument clamp 21. The first connecting block 9, the second connecting block 14, the first hinge block 5, and the second hinge block 19 have the same overall structure and the same fitting method. The second hinge block 19 is threaded with a screw through the third threaded hole 22. The first hinge block 5 is set horizontally, and the second hinge block 19 is set vertically. By loosening the screw at the third threaded hole 22 on the second hinge block 19, the measuring rod 20 can be moved, thereby adjusting the distance between the measuring instrument at the instrument clamp 21 and the workpiece to meet the measurement requirements.

[0018] The working principle of this utility model is as follows: During measurement, the base 1 is fixed on the fulcrum seat. Then, the screw in the threaded hole 3 is loosened to allow the column 4 to slide in the sliding hole 2. The screw is then tightened to fix it, thereby adjusting the extension length of the column 4 so that it does not interfere with the processed product when the column 2 13 is vertical. Then, the screw at one end of the internal threaded tapered nest 10 on the connecting block 9 is loosened so that the connecting block 9 can rotate on the hinge block 5, thereby adjusting the angle of the column 2 13 and keeping the column 2 13 vertical. Finally, the screw is tightened to fix it using the washer 23. Next, tighten the screws at one end of the internal threaded tapered nest 10 on the connecting block 2 14 and the screws at the threaded hole 2 12 on one side of the connecting block 2 14, so that the connecting block 2 14 and the hinge block 2 19 can rotate and the connecting block 2 14 can slide on the column 2 13. Then tighten the screws to fix it, thereby adjusting the height and angle of the hinge block 2 19, so that the measuring point of the measuring instrument on the instrument clamp 21 at one end of the measuring rod 20 can be on the same axis as the front support point, thereby measuring the maximum diameter of the product. The staff can also loosen the screws on one side of the adjustment hole 29 on the limit block 15 to make the positioning column 31 slide within the adjustment hole 29. By moving the positioning column 31, a distance is created between the positioning column 31 and the measuring rod 20, or the positioning column 31 can be directly used to push the measuring rod 20, thereby making small adjustments to the height and angle of the measuring rod 20. During the process, the measuring rod 20 and the positioning column 31 come into contact.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
