Description

Technical Field

[0001] This invention relates to the field of cutting tools, and in particular to a cutting tool with a cooling structure for machine tool processing. Background Technology

[0002] Most existing cutting tools with cooling structures used in boring machines adopt an internal cooling channel design. The tool tip has a built-in coolant channel, and the coolant is directly delivered to the cutting area through the spindle or tool holder. This design can achieve directional cooling, which is especially suitable for deep hole machining. Compared with external spray cooling, the cooling efficiency is improved by more than 30%.

[0003] In practical use, most cutting tools are fixedly connected by bolts. Bolting is the most mainstream way to connect tools to tool holders, tool pedestals, or spindles. Its core advantages are simple structure, low cost, strong versatility, and the ability to ensure connection rigidity through preload. However, when changing cutting tools of different specifications according to actual needs (e.g., tool wear), bolt fixing requires manual removal of old bolts and tools using wrenches and other tools, followed by installation of new tools and retightening of bolts. The whole process is cumbersome. For scenarios that require frequent tool changes (such as multi-variety, small-batch processing), it will significantly increase non-cutting auxiliary time and reduce the overall processing efficiency of the machine tool.

[0004] Therefore, it is necessary to propose a cutting tool with a cooling structure for machine tool processing to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a cutting tool with a cooling structure for machine tool processing, which can effectively solve the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A cutting tool with a cooling structure for machine tool processing includes a cutting tool body, a mounting plate slidably connected to one end of the cutting tool body, a transverse groove formed on the surface of the mounting plate, symmetrically formed mounting slots on the surface of the cutting tool body, and a connecting channel formed on the surface of the cutting tool body near the end of the mounting plate. A heat dissipation plate is slidably connected to the wall of the mounting slot. A first connecting pipe is fixedly connected to the end of the connecting channel near the transverse groove. A second connecting pipe is slidably inserted into the surface of the first connecting pipe. A movable block is fixedly connected to the end of the second connecting pipe away from the cutting tool body. Connecting springs are symmetrically fixedly connected to the surface of the movable block. A strip-shaped hole is formed on the surface of the mounting plate away from the cutting tool body. The ends of the two connecting springs away from the movable block are fixedly connected to the wall of the strip-shaped hole. The transverse groove wall is symmetrically provided with multiple circular grooves, and the cutting tool body surface near the strip hole is symmetrically provided with sliding grooves. The sliding groove walls are provided with adjustment mechanisms for adjusting the installation and positioning of the cutting tool body. The adjustment mechanism includes a U-shaped block slidably connected to the wall of a groove. The surface of the U-shaped block is symmetrically provided with a first column groove. A T-shaped block is slidably connected to the wall of the first column groove. The T-shaped block is slidably inserted into a circular groove. A first spring is fixedly connected to the end of the T-shaped block away from the circular groove. An inclined groove is symmetrically provided on the surface of the U-shaped block away from the strip hole. A connecting groove is provided on the wall of the inclined groove. A protruding post is slidably connected to the wall of the connecting groove. A connecting plate is fixedly connected to the end of each of the two protruding posts away from the connecting groove. An adjusting ring is installed on the end of each of the four connecting plates away from the protruding posts by a torsion spring. The adjusting ring is sleeved on the surface of the cutting tool body.

[0007] Preferably, the wall of the strip hole is provided with a first limiting groove, and the movable block is slidably connected to the first limiting groove; folding curtains are symmetrically fixedly connected to the surface of the movable block, and the ends of the plurality of folding curtains away from the movable block are fixedly connected to the wall of the strip hole.

[0008] Preferably, a fixing block is fixedly connected at equal intervals to one end of the mounting groove wall near the strip hole, and grooves are equally spaced at one end of each of the two heat sinks near the strip hole. The grooves are engaged with the fixing blocks, and protrusions are symmetrically fixedly connected to one end of the heat sink surface away from the grooves. Both protrusions are slidably connected to the mounting groove.

[0009] Preferably, the adjusting ring has symmetrical vertical grooves on its surface, and an arc-shaped block is fixedly connected to the surface of the cutting tool body next to the vertical groove. A second spring is fixedly connected to the surface of the arc-shaped block near the vertical groove. The end of the second spring away from the arc-shaped block is fixedly connected to the groove wall of the vertical groove. A vertical column is fixedly connected to the groove wall of the vertical groove, and the second spring is sleeved on the outside of the vertical column.

[0010] Preferably, the second spring is initially in a compressed state.

[0011] Preferably, the end of the connecting groove wall away from the inclined groove has an arc-shaped groove, and the arc-shaped groove is installed in conjunction with the protruding post.

[0012] Preferably, a first stop is installed on the wall of the connecting groove near the arc-shaped groove by a torsion spring, and a second stop is provided in the connecting groove next to the first stop, with the second stop being installed between the connecting groove wall and the torsion spring.

[0013] Preferably, a fixing plate is fixedly connected to the surface of the adjusting ring between the two vertical grooves. The end faces of the two fixing plates away from the adjusting ring are symmetrically provided with second column grooves. T-shaped rods are slidably connected to the groove walls of the second column grooves. A locking block is fixedly connected to one end of the two T-shaped rods away from the fixing plate. A third spring is fixedly connected to one end of the two T-shaped rods away from the locking block.

[0014] Compared with the prior art, the present invention provides a cutting tool with a cooling structure for machine tool processing, which has the following beneficial effects: This machine tool is used for machining cutting tools with a cooling structure. When changing cutting tools of different specifications, it avoids the need to fix the cutting tools by bolting. This optimizes the installation operation steps of the cutting tool body. In addition, when adjusting the T-block and the circular groove, the adjusting ring moves to the end of the heat sink plate that is away from the slot when it contacts the mounting groove, thus limiting the installation of the heat sink plate and ensuring that it does not separate from the mounting groove. In other words, the installation positioning between the cutting tool body and the mounting plate is completed at the same time as limiting the installation of the mounting plate. This saves time when frequently changing tools and improves the installation efficiency of the cutting tool body.

[0015] The machine tool uses cutting tools with a cooling structure. The connecting plate and the adjusting ring are installed by a torsion spring. Utilizing the elastic force of the torsion spring, after the convex post and the U-shaped block come into contact, during the relative movement between the convex post and the inclined groove, the two U-shaped blocks can move away from each other. Utilizing the elastic force of the torsion spring, after the convex post and the arc groove are engaged, the stable engagement between the T-shaped post and the circular groove can still be ensured, which means that the stability of the cutting tool body after installation can be guaranteed.

[0016] This machine tool uses cutting tools with a cooling structure. During the installation and positioning of the cutting tool body, the first connecting pipe and the second connecting pipe are slidably inserted. The movable block, the first connecting pipe, the second connecting pipe, and the connecting channel form a coolant flow channel. During the coolant flow, the heat generated in the cutting tool body due to cutting is carried away. The coolant can also wash over the end of the cutting tool body away from the mounting plate, carrying away the heat generated at the contact point between the cutting tool body and the workpiece. In other words, the coolant flow channel is set up and the heat sink is installed and positioned simultaneously during the installation of the cutting tool and the mounting plate, which significantly reduces non-cutting auxiliary time and improves the overall machining efficiency.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10A cutting tool with a cooling structure for machine tool processing includes a cutting tool body 1, a mounting plate 11 slidably connected to one end of the cutting tool body 1, a transverse groove 12 formed on the surface of the mounting plate 11, mounting slots 13 symmetrically formed on the surface of the cutting tool body 1, and a connecting channel 14 formed on the surface of the cutting tool body 1 near the end of the mounting plate 11. A heat dissipation plate 2 is slidably connected to the wall of the mounting slot 13. A first connecting pipe 3 is fixedly connected to the end of the connecting channel 14 near the transverse groove 12. A second connecting pipe 4 is slidably inserted into the surface of the first connecting pipe 3. A movable block 5 is fixedly connected to the end of the second connecting pipe 4 away from the cutting tool body 1. Connecting springs 6 are symmetrically fixedly connected to the surface of the movable block 5. A strip hole 7 is formed on the surface of the mounting plate 11 away from the cutting tool body 1. The ends of the two connecting springs 6 away from the movable block 5 are fixedly connected to the wall of the strip hole 7. The transverse groove 12 has multiple circular grooves 9 symmetrically opened on its groove wall. The cutting tool body 1 has a sliding groove 10 symmetrically opened on one end of its surface near the strip hole 7. The groove walls of the multiple sliding grooves 10 are provided with adjustment mechanisms 8 for adjusting the installation and positioning of the cutting tool body 1. The adjustment mechanism 8 includes a U-shaped block 81 slidably connected to the wall of the slide groove 10. A first column groove 82 is symmetrically opened on the surface of the U-shaped block 81. A T-shaped block 83 is slidably connected to the wall of the first column groove 82. The T-shaped block 83 is slidably inserted into the circular groove 9. A first spring 84 is fixedly connected to the end of the T-shaped block 83 away from the circular groove 9. An inclined groove 85 is symmetrically opened on the surface of the U-shaped block 81 away from the strip hole 7. A connecting groove 86 is opened on the wall of the inclined groove 85. A protruding post 87 is slidably connected to the wall of the connecting groove 86. A connecting plate 88 is fixedly connected to the end of each of the two protruding posts 87 away from the connecting groove 86. An adjustment ring 89 is installed on the end of each of the four connecting plates 88 away from the protruding posts 87 through a torsion spring. The adjustment ring 89 is sleeved on the surface of the cutting tool body 1. It should be noted that, in the initial state, the adjusting ring 89 is not in contact with the heat sink 2, the groove 132 on the surface of the heat sink 2 is engaged with the fixing block 131, and the locking block 898 is not in contact with the surface of the U-shaped block 81. When the cutting tool body 1 and the mounting plate 11 are fitted together, the locking block 898 first contacts the surface of the U-shaped block 81, and relative movement occurs between the T-shaped rod 897 and the second column groove 896, compressing the third spring. Then, the protruding post 87 contacts the inclined groove 85 and relative movement occurs, causing the two U-shaped blocks 81 to move towards each other. Moving away, the protrusion 87 then contacts the connecting groove 86 and moves relative to it. The first stop block 862 blocks the protrusion 87, allowing it to engage with the arc groove 861. At this time, the second spring 893 is compressed, ensuring a stable engagement between the protrusion 87 and the arc groove 861. During this process, the T-shaped block 83 engages with the circular groove 9. The locking block 898 is positioned between the U-shaped block 81 and the cutting tool body 1 under the action of the third spring, ensuring the stable installation of the cutting tool body 1. By adjusting the movement of the adjusting ring 89, the two U-shaped blocks 81 can move away from each other. The T-shaped block 83 cooperates with the circular groove 9 to install and position the cutting tool body 1, thus completing the installation between the cutting tool body 1 and the mounting plate 11. This avoids the need to use bolts to fix the cutting tool when changing different specifications of cutting tools, and optimizes the installation operation steps of the cutting tool body 1. That is, the installation positioning between the cutting tool body 1 and the mounting plate 11 is completed while the mounting plate is installed and limited, thereby saving time and improving the installation efficiency of the cutting tool body 1 when frequently changing tools. During the installation and positioning of the cutting tool body 1, the first connecting pipe 3 and the second connecting pipe 4 are first slidably inserted. The movable block 5, the first connecting pipe 3, the second connecting pipe 4 and the connecting channel 14 form a coolant flow channel. During the flow of coolant, the heat generated in the cutting tool body 1 due to cutting is carried away. The coolant can also be flushed on the end of the cutting tool body 1 away from the mounting plate 11, carrying away the heat generated at the contact point between the cutting tool body 1 and the workpiece. In other words, the coolant flow channel is set up and the heat sink 2 is installed and positioned simultaneously during the installation of the cutting tool and the mounting plate 11, which significantly reduces non-cutting auxiliary time and improves the processing efficiency of the entire machine tool.

[0021] Please see Figure 1 and Figure 3 The wall of the strip hole 7 is provided with a first limiting groove 71, and the movable block 5 is slidably connected to the first limiting groove 71; folding curtains 72 are symmetrically fixedly connected to the surface of the movable block 5, and the ends of the multiple folding curtains 72 away from the movable block 5 are all fixedly connected to the wall of the strip hole 7. It should be noted that the first limiting groove 71 ensures stable installation between the movable block 5 and the strip hole 7, preventing the movable block 5 from separating from the strip hole 7, and the folding curtain 72 can shield the connecting spring 6.

[0022] Please see Figure 9 and Figure 10 A fixing block 131 is fixedly connected at equal intervals to one end of the mounting groove 13 near the strip hole 7. The two heat sinks 2 are provided with grooves 132 at equal intervals at one end near the strip hole 7. The grooves 132 are engaged with the fixing blocks 131. The heat sink 2 is symmetrically fixedly connected with protrusions 133 at one end away from the grooves 132. Both protrusions 133 are slidably connected to the mounting groove 13. It should be noted that the groove 132 and the fixing block 131 can be engaged to perform initial installation and positioning of the heat sink 2, and the protrusion 133 cooperates with the groove 132 to give the heat sink 2 sufficient room to move on the surface of the mounting groove 13, so as to facilitate the installation and disassembly of the heat sink 2 and the mounting groove 13.

[0023] Please see Figure 8 and Figure 9 The adjusting ring 89 has symmetrical vertical grooves 891 on its surface. The cutting tool body 1 has an arc-shaped block 892 fixedly connected to the surface next to the vertical groove 891. The surface of the arc-shaped block 892 near the vertical groove 891 is fixedly connected to a second spring 893. The end of the second spring 893 away from the arc-shaped block 892 is fixedly connected to the groove wall of the vertical groove 891. The groove wall of the vertical groove 891 is fixedly connected to a vertical column 894. The second spring 893 is sleeved on the outside of the vertical column 894.

[0024] Please see Figure 8 The initial state of the second spring 893 is that it is compressed; It should be noted that the reaction force generated by the compression of the second spring 893 acts on the surface of the vertical groove 891. After the protrusion 87 and the arc groove 861 are engaged, the elastic force of the second spring 893 can further ensure the stability of the engagement between the two.

[0025] Please see Figure 6 An arc-shaped groove 861 is provided at one end of the connecting groove 86 away from the inclined groove 85, and the arc-shaped groove 861 is installed in conjunction with the protruding post 87. Please see Figure 6 A first stop 862 is installed on the wall of the connecting groove 86 near the arc groove 861 by a torsion spring. A second stop 863 is provided in the connecting groove 86 next to the first stop 862. The second stop 863 is installed between the connecting groove 86 and the wall of the connecting groove 86 by a torsion spring. It should be noted that the arrangement of the first stop 862 and the second stop 863 allows the protrusion 87 to contact the first stop 862 first and move relative to it during the relative movement between the protrusion 87 and the connecting groove 86. Since the connecting plate 88 and the adjusting ring 89 are mounted via a torsion spring, the protrusion 87 can engage with the arc-shaped groove 861 as the adjusting ring 89 moves, while simultaneously separating from the first stop 862. The first stop 862 is mounted with the groove wall of the connecting groove 86 via a torsion spring, and the first stop 862 can return to its initial state under the force of the torsion spring. Then, during the subsequent adjustment of the adjusting ring 89 towards the mounting plate 11, the protrusion 87 can engage with the first stop 862. The surfaces of the two stops 863 are in contact and move relative to each other. The second stop 863 is also installed with the wall of the connecting groove 86 by a torsion spring. When the protrusion 87 moves from the arc groove 861 to the lowest point of the connecting groove 86, the second stop 863 can also return to the initial state under the action of the torsion spring. During the separation of the protrusion 87 from the connecting groove 86, the second stop 863 can restrict the protrusion 87 so that it will no longer cooperate with the arc groove 861. The protrusion 87 can be smoothly separated from the connecting groove 86 and no longer limit the U-shaped block 81, which facilitates the disassembly and separation of the T-shaped block 83 and the circular groove 9, and also facilitates the installation and disassembly of the cutting tool body 1 and the mounting plate 11.

[0026] Please see Figure 2 and Figure 7 A fixing plate 895 is fixedly connected to the surface of the adjusting ring 89 between two vertical grooves 891. The end faces of the two fixing plates 895 away from the adjusting ring 89 are symmetrically provided with second column grooves 896. T-shaped rods 897 are slidably connected to the groove walls of the second column grooves 896. A locking block 898 is fixedly connected to one end of the two T-shaped rods 897 away from the fixing plate 895. A third spring is fixedly connected to one end of the two T-shaped rods 897 away from the locking block 898. It should be noted that during the process of adjusting the ring 89 moving towards the strip hole 7, the locking block 898 can first contact the surface of the U-shaped block 81, and then the protrusion 87 contacts the inclined groove 85 on the surface of the U-shaped block 81. Immediately afterwards, relative movement occurs between the T-shaped rod 897 and the second column groove 896, and the third spring is gradually compressed. After the T-shaped block 83 is inserted into the circular groove 9, the locking block 898 can be placed between the U-shaped block 81 and the cutting tool body 1 and the U-shaped block 81, so that the cutting tool body 1 can be locked, thereby ensuring its stability after installation and positioning. It should be noted that a connecting shaft can be fixedly connected to the surface of the mounting plate 11 away from the cutting tool body 1. The end of the connecting shaft away from the mounting plate 11 can be fixedly connected to the boring machine. By adjusting the movement of the connecting shaft and the mounting plate 11, the cutting tool body 1 can move together with the mounting plate 11 to bring it closer to the workpiece and perform boring on the hole set on the surface of the workpiece.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
