Description

Technical Field

[0001] This utility model relates to the field of PCD reamer technology, and more specifically, to a novel PCD reamer that can be installed on a CNC machine tool. Background Technology

[0002] PCD reamers are superhard cutting tools made of diamond and applied to cutting processes. Diamond tools possess characteristics such as high hardness, high compressive strength, good thermal conductivity, and good wear resistance, enabling them to achieve high machining accuracy and efficiency in high-speed cutting. When working on CNC machine tools, PCD reamers are mainly used to process workpieces. For example, the patent with prior art announcement number CN219443695U discloses a positive and negative chamfering PCD reamer. The upper, middle, and lower tool posts are inserted into the fixed and limiting posts through the upper, middle, and lower limit slots, and fixed with a fixing nut. The combined chamfering PCD reamer is fixed to the machine tool through the tool holder. The machine tool controls the combined chamfering PCD reamer to contact the workpiece through the tool holder, and switches between upper, middle, and lower polycrystalline diamond inserts.

[0003] When the above-mentioned device is used, it avoids the inconvenience of chamfering workpieces, making the chamfering PCD reamer more convenient to use and facilitating the replacement of damaged tool holders. However, the fixed column is prone to damage and breakage after long-term use, making it very inconvenient to repair the CD reamer, which can only be discarded, thus affecting the work of the staff.

The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0028] This utility model provides a novel PCD reamer for installation on CNC machine tools, such as... Figure 1 , 2 As shown in Figure 3, it includes a reamer mounting sleeve 1, with a first reamer connecting rod 9 on its inner end face, a first reamer block 2 on the outer end face of the first reamer connecting rod 9, and a locking mounting groove 6 on the outer side of one end of the third reamer block 4.

[0029] The locking mounting groove 6 is provided with an internal hexagonal locking bolt 5, one end of the first reamer connecting rod 9 is provided with a limiting mounting plate 7, the first reamer connecting rod 9 is provided with a water guide hole 8, and the specifications of the first reamer block 2, the second reamer block 3 and the third reamer block 4 are set in a sequentially decreasing state.

[0030] like Figure 4 and 5 As shown, the reamer mounting sleeve 1 has a circular groove 18 inside, and a concave slot 19 is opened inside the circular groove 18. The outer end face of the first reamer connecting rod 9 is provided with a first adapter slider 10, which can easily insert the first reamer connecting rod 9 into the circular groove 18. At the same time, the first adapter slider 10 can also be inserted into the concave slot 19. So when the reamer mounting sleeve 1 is installed on the CNC machine tool and rotates, the first reamer connecting rod 9 can be driven to rotate through the first adapter slider 10 and the concave slot 19. The outer end face of the second reamer connecting rod 11 is provided with a second reamer block 3.

[0031] The outer end face of the third reamer connecting rod 12 is provided with a third reamer block 4. The operator sequentially places the first reamer block 2, the second reamer block 3, and the third reamer block 4 onto the outer end faces of the first reamer connecting rod 9, the second reamer connecting rod 11, and the third reamer connecting rod 12, and then sequentially places the limiting grooves 25 inside the first reamer block 2, the second reamer block 3, and the third reamer block 4 onto the outer end faces of the first adapter slider 10, the second adapter slider 13, and the third adapter slider 14. Since the limiting grooves 25 inside the first reamer block 2, the second reamer block 3, and the third reamer block 4 are in close contact with the outer end faces of the first adapter slider 10, the second adapter slider 13, and the third adapter slider 14, it is easy to disassemble and replace the first reamer block 2, the second reamer block 3, and the third reamer block 4 when they are damaged. At the same time, when the first reamer connecting rod 9 rotates, it can stably drive the first reamer block 2, the second reamer block 3, and the third reamer block 4 to rotate.

[0032] The inner side of one end of the third reamer connecting rod 12 is provided with a locking thread groove 15, which allows one end of the threaded rod of the internal hexagonal locking bolt 5 to pass through the inside of the locking mounting groove 6 and insert one end of the threaded rod into the inside of the locking thread groove 15. When the locking thread groove 15 rotates continuously, it can squeeze the first reamer block 2, the second reamer block 3 and the third reamer block 4 together, thereby tightening the first reamer connecting rod 9 inside the reamer mounting sleeve 1, so that the limiting mounting plate 7 fits tightly against the concave limiting groove 20. The first reamer block 2, the second reamer block 3, and the third reamer block 4 are stably installed on the outer end faces of the first reamer connecting rod 9, the second reamer connecting rod 11, and the third reamer connecting rod 12. A concave limiting groove 20 is provided on the outer side of one end of the reamer mounting sleeve 1. When the first reamer connecting rod 9 is inserted into the circular sliding groove 18, the limiting mounting plate 7 will be inserted into the concave limiting groove 20. A second reamer connecting rod 11 is provided on the side of the first reamer connecting rod 9 away from the limiting mounting plate 7.

[0033] One end of the second reamer connecting rod 11 is provided with a third reamer connecting rod 12. The outer end face of the second reamer connecting rod 11 is provided with a second adapter slider 13. One side of the outer end face of the third reamer connecting rod 12 is provided with a third adapter slider 14. One side end face of the second adapter slider 13 is provided with a first concave water guide groove 16.

[0034] The first adapter slider 10 has a second concave water guide groove 17 on one end face. When the reamer mounting sleeve 1 is installed inside the CNC lathe for operation, the first reamer block 2, the second reamer block 3, and the third reamer block 4 will generate high temperatures. The CNC lathe will cool the first reamer block 2, the second reamer block 3, and the third reamer block 4 through coolant. The coolant of the CNC lathe will be introduced into the water guide hole 8. The coolant inside the water guide hole 8 will be introduced into the first concave water guide groove 16 and the second concave water guide groove 17, and discharged from the concave drainage groove 26, thereby cooling the first reamer block 2, the second reamer block 3, and the third reamer block 4, thus ensuring the service life of the first reamer block 2, the second reamer block 3, and the third reamer block 4. The inner end face of the circular slide groove 18 is adapted to the outer end face of the first reamer connecting rod 9, and the inner end face of the concave slot 19 is adapted to the outer end face of the first adapter slider 10.

[0035] The outer end face of the internal hexagonal locking bolt 5 is connected to the inner end face of the locking thread groove 15 by threads. The inner end face of the concave limiting groove 20 is adapted to the outer end face of the limiting mounting plate 7. The first concave water guide groove 16 and the second concave water guide groove 17 are both connected to the water guide hole 8.

[0036] like Figure 6 As shown, the first reamer block 2, the second reamer block 3 and the third reamer block 4 are all provided with mounting grooves 24 inside, and the mounting grooves 24 are provided with limiting sliding grooves 25 inside. One end of the first reamer block 2 and the second reamer block 3 is provided with a supporting top plate 27.

[0037] The end face of the supporting top plate 27 is provided with a concave drainage groove 26. When the first reamer block 2, the second reamer block 3 and the third reamer block 4 are installed, they will press against the supporting top plate 27 at the corresponding positions in sequence, so that a water guiding gap is reserved inside the concave drainage groove 26, so that the coolant can flow out from the inside of the concave drainage groove 26, thereby cooling the first reamer block 2, the second reamer block 3 and the third reamer block 4. A tool groove 21 is provided on one side of the outer end face of the first reamer block 2, the second reamer block 3 and the third reamer block 4. A blade 22 is provided on one side of the inner end face of the tool groove 21. The tool groove 21 can effectively increase the stability of the blade 22 installation, so that the workpiece can be cut by the blade 22. A mounting bolt 23 is provided in the middle of the upper end of the blade 22, and the blade 22 is locked and fixed by the mounting bolt 23.

[0038] The outer end face of the second reamer connecting rod 11 is adapted to the outer end face of the inner mounting groove 24 of the second reamer block 3. The inner end face of the inner mounting groove 24 of the third reamer block 4 is adapted to the outer end face of the third reamer connecting rod 12. The inner end face of the limiting slide groove 25 is adapted to the outer end face of the second adapting slider 13. After the reamer mounting sleeve 1, the first reamer block 2, the second reamer block 3 and the third reamer block 4 are installed, the operator can install the reamer mounting sleeve 1 inside the CNC machine tool and drive the reamer mounting sleeve 1 to rotate through the CNC machine tool, thereby performing cutting work on the workpiece.
