Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a boring bar assembly and machining equipment. Background Technology

[0002] In machining processes, boring operations on parts with large hole depths often present numerous challenges. For example, when the hole depth is 290mm, conventional boring bar holders, such as Φ70 with a length of 280mm, cannot meet the requirements for machining deep holes. However, arbitrarily increasing the length of the boring bar can easily lead to a decrease in its rigidity, causing vibration during machining, which in turn affects machining accuracy, reduces machining efficiency, increases production costs, and lowers the product yield.

[0003] Therefore, there is an urgent need for a boring bar assembly and processing equipment to solve the above-mentioned technical problems. Utility Model Content

[0012] Preferably, the first connecting part is provided with a connecting hole, and the second connecting part can be interference-fitted with the connecting hole.

[0013] Preferably, the end of the boring bar without the cutting tool is directly interference-fitted with the connecting rod.

[0014] Preferably, the connecting rod includes a straight rod and a bent rod.

[0015] Preferably, at least some of the straight rods have different axial lengths.

[0016] Preferably, at least some of the bent rods have different bending angles.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] To address the problem of deep hole machining, this utility model provides a boring bar assembly for connecting cutting tools and machine tools. For example... Figures 1-4 As shown, the kit includes a boring bar 10 and a connecting rod 20; wherein, one end of the boring bar 10 is provided with a mounting hole along the radial direction, and the mounting hole can be used to install a cutting tool 100; one end of the connecting rod 20 is provided with a first connecting part 21, and the other end is provided with a second connecting part 22. Multiple connecting rods 20 are provided, and any two connecting rods 20 can be combined through the first connecting part 21 and the second connecting part 22. The first connecting part 21 can be connected to the boring bar 10, and the second connecting part 22 can be connected to the machine tool.

[0042] In this structure, when encountering deep hole machining, the corresponding number of connecting rods 20 can be selected according to the actual length of the deep hole, and multiple connecting rods 20 are connected in sequence. Finally, the first connecting part 21 of the assembled connecting rod 20 is connected to the boring bar 10, and the second connecting part 22 is connected to the machine tool. This setting not only allows the tool 100 to extend into the deep hole, but also does not reduce the rigidity of the boring bar 10, thereby effectively avoiding the vibration phenomenon, ensuring machining accuracy, improving machining efficiency, and ensuring the yield of products.

[0043] Example 1

[0044] like Figures 1-4As shown, the first connecting part 21 is provided with a connecting hole, and the second connecting part 22 can be threaded into the connecting hole. This arrangement can further improve the convenience of assembling multiple connecting rods 20, as multiple connecting rods 20 can be assembled into a whole simply by screwing, thus improving assembly efficiency.

[0045] In addition, such as Figure 1 and Figure 2 As shown, the boring bar 10 has a countersunk hole 11 along the axial direction. The first locking member 30 can pass through the countersunk hole 11 and be threaded into the connecting hole. This arrangement can further improve the ease of assembly between the boring bar 10 and the connecting rod 20. At the same time, the first locking member 30 is located inside the countersunk hole 11, which can prevent the appearance of a protruding structure on the outer periphery of the boring bar 10, thereby preventing it from touching the inner wall of the deep hole during the machining process.

[0046] It should be noted that in this embodiment, the first locking member 30 is an internal hexagon screw, which not only saves space but also can bear a large torque, thereby ensuring that the combination of the boring bar 10 and the connecting rod 20 has a high tensile strength, thus improving the service life of the assembly.

[0047] Furthermore, multiple connecting holes can be provided on the first connecting part 21, allowing operators to select the appropriate connecting hole when assembling multiple connecting rods 20, based on actual conditions. Correspondingly, multiple countersunk holes 11 are also provided on the boring bar 10, and the boring bar 10 is connected to the connecting rod 20 via multiple first locking members 30, which not only improves the flexibility of the connection but also enhances the stability of the connection between the boring bar 10 and the connecting rod 20. Figure 1 and Figure 2 As shown, in this embodiment, the boring bar 10 and the connecting rod 20 are locked by two first locking members 30. In other embodiments, the number of first locking members 30 can be adjusted according to actual needs, as long as it ensures that multiple connecting rods 20 can be combined and connected, and that the connecting rods 20 and the boring bar 10 can be combined and connected.

[0048] Furthermore, this embodiment also provides a structure in which the end of the boring bar 10 without the cutting tool 100 can directly engage with the threaded connection hole. That is, in this structure, without the aid of the first locking member 30, a threaded protrusion is directly machined on the end of the boring bar 10 without the cutting tool 100, and this threaded protrusion directly engages with the threaded connection hole of the connecting rod 20, thereby further improving the ease of assembly and reducing the assembly difficulty of the boring bar 10 and the connecting rod 20.

[0049] It should be noted that when machining shallow holes, the connecting rod 20 can be used directly without the need for the connecting rod 20. The boring bar 10 can be directly installed on the machine tool for machining according to the actual structure (through the first locking member 30 or the threaded protrusion mentioned above). When machining deep holes, the corresponding number of connecting rods 20 can be selected for assembly according to the specific length of the deep hole.

[0050] Example 2

[0051] The first connecting part 21 is provided with a connecting hole, and the second connecting part 22 can be interference-fitted with the connecting hole. This arrangement can improve the convenience of disassembly and assembly while ensuring that multiple connecting rods 20 can be arbitrarily combined. The interference fit has good load-bearing capacity and anti-loosening properties, and is widely applicable, which is conducive to improving positioning accuracy.

[0052] In this embodiment, the end of the boring bar 10 without the cutting tool 100 can be directly interference-fitted with the connecting rod 20. This method can further improve the assembly efficiency of the kit and ensure the consistency of the assembly method.

[0053] Based on the two embodiments described above, such as Figure 3 and Figure 4 As shown, the connecting rod 20 includes a straight rod and a bent rod. Operators can select either a straight rod or a bent rod according to actual processing needs, thereby further improving processing flexibility and operability, and further reducing processing difficulty.

[0054] Example 3

[0055] like Figure 3 As shown, at least some of the straight rods have different axial lengths. This arrangement further extends the selectivity of length, allowing for the combination of connecting rods 20 of different lengths according to different deep hole lengths, thereby enabling the boring bar 10 to reach the most suitable length.

[0056] It should be noted that the length of common deep holes is generally above 290mm. The boring bar 10 in this embodiment is 280mm, and the straight bar has different sizes ranging from 5mm to 40mm. Different lengths of straight bars can be selected according to actual needs, thereby meeting the usage requirements and improving the convenience of processing.

[0057] Example 4

[0058] like Figure 4 As shown, at least some of the bent rods have different bending angles. When dealing with complex deep hole structures that cannot be directly machined using straight rods, bent rods can be used for machining. Furthermore, different degrees of bending rods can be combined according to the actual situation until the cutting tool 100 can successfully machine the hole.

[0059] It should be noted that the connecting rod 20 in this embodiment has a bending angle of 15°-45°. The operator can assemble connecting rods 20 with different bending angles according to actual needs, or choose a combination of bent rods and straight rods, so as to meet different processing needs, improve the convenience and flexibility of processing, and thus ensure processing efficiency and processing accuracy.

[0060] Based on the above, this embodiment also provides a processing device, which includes a cutting tool 100, a machine tool, and the aforementioned boring bar assembly. The cutting tool 100 is installed in the mounting hole of the boring bar 10. The top end of the boring bar 10 has multiple locking holes along the axial direction, and these locking holes communicate with the mounting hole. A second locking member 40 can enter the locking hole and lock the cutting tool 100 in the mounting hole. Additionally, the second connecting part 22 of the connecting rod 20 is connected to the machine tool. It should be noted that the second locking member 40 is an internal hexagon screw. Using this boring bar assembly improves the convenience and accuracy of machine tool processing, and the cutting tool 100 and the boring bar 10 are detachably connected, facilitating timely replacement or maintenance of the cutting tool 100.

[0061] In summary, the boring bar assembly provided by this utility model can solve the problem of deep hole machining. While ensuring the rigidity of the boring bar 10, it extends the length of the boring bar 10 to guarantee machining accuracy. Using this assembly in the machining equipment can significantly improve machining efficiency and product yield.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
