Description

Technical Field

[0001] The present invention belongs to the technical field of chamfering tools, and particularly relates to a coated combined chamfering tool. Background Art

[0002] A chamfering tool is a tool used for machining the edges of workpieces in metal processing, mainly used to remove the acute angles at the edges of workpieces to make them smooth and beautiful. The chamfering tool can be assembled on machine tools such as milling machines, drilling machines, planing machines, and chamfering machines. Among them, a coated chamfering tool refers to a tool with a layer or multiple layers of special materials coated on the surface of the blade of the chamfering tool to improve its performance and durability. Common coated chamfering tools include PVD-coated chamfering tools and titanium-plated chamfering tools. The coating materials usually have high hardness and can resist wear and deformation.

[0003] For example, a combined tungsten steel chamfering tool disclosed in the national patent publication number CN217166637U includes a tool head and a tool holder; a tool holder is provided at the bottom end of the tool head, and a connecting mechanism is provided between the tool holder and the tool head; the connecting mechanism includes a connecting column, a limiting groove, a limiting block, a connecting plate, a sleeve block, a sleeve groove, a return spring, a sliding component, and a positioning component. The connecting column is fixedly connected to the bottom end of the tool head, and the connecting column is inserted into the top end of the tool holder. The limiting groove is opened on one side of the bottom end of the connecting column. One side of the limiting block is engaged with the limiting groove, and the other side of the limiting block penetrates through the tool holder and extends to the outside of the tool holder. One end of the connecting plate is fixedly connected to the limiting block. The sleeve block is fixedly connected to the end of the connecting plate away from the limiting block, and the sleeve block is inserted into the inside of the sleeve groove. The sleeve groove is opened on one side of the tool holder. The function of conveniently connecting the tool head and the tool holder is realized through the connecting mechanism.

[0004] However, the traditional device still has the following problems when in use:

[0005] Since the chamfering tool rotates at a high speed when used on a milling machine, when the tool stops rotating, the orientation of the disassembly port is random and it cannot be ensured to face forward. The randomly stopped angle is difficult to ensure convenient disassembly by the staff, and the cutting tool is sharp, so it is also difficult for the staff to manually correct the angle of the tool. Therefore, we need a method that does not require the staff to adjust the orientation and can be automatically disassembled. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a coated combined chamfering tool, which has the advantages of not requiring the staff to adjust the orientation and being able to be automatically disassembled.

[0018] In the present invention, when the chamfering cutter head needs to be repaired or the model needs to be replaced, the chamfering cutter head rotating slowly and decelerating will gradually longitudinally fit onto the arc-shaped groove under the drive of the displacement motor. The special arc shape of the arc-shaped groove can meet the free rotation of the bottom of the chamfering cutter head. When the chamfering cutter head still has a certain rotation speed at this time, the rapid movement of the chamfering cutter head cannot generate sufficient magnetic suction force on the limit insertion plate. When the chamfering cutter head completely decelerates and slowly rotates until the bottom inclined surface of the chamfering cutter head is parallel to the top inclined surface of the limit insertion plate, the magnetic suction force between the two is maximized. At this time, the limit insertion plate will be magnetically adsorbed and move longitudinally upward, fitting on the outer wall of the bottom of the chamfering cutter head, and combining with the middle layer to form a complete base to hold the chamfering cutter head and fix it. Through this combination method, the rotation angle of the chamfering cutter head can be captured and fixed in real time, without deliberately controlling and adjusting the rotation of the chamfering cutter head, without the need for staff to adjust the orientation, and it can be automatically disassembled, thus facilitating the repair or model replacement of the chamfering cutter head.

[0039] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0040] Embodiment 1, please refer to Figures 1 to 19, the present invention provides a technical solution: a coated combined chamfering tool, including a numerical control milling machine 1. A central control platform 47 is fixedly installed on the outer wall of one side of the numerical control milling machine 1. A cutting drill rod 2 is fixedly installed at the axis of the displacement motor of the numerical control milling machine 1. A chamfering cutter head 3 is movably inserted into the outer wall of the bottom of the cutting drill rod 2. The outer wall of the chamfering cutter head 3 is coated with a tungsten carbide coating. The numerical control milling machine 1 is provided with a processing area platform and a maintenance area platform. An installation frame 4 is fixedly installed on the surface of the maintenance area platform. A holding machine tool 14 is slidably connected to the inner wall of the installation frame 4. The holding machine tool 14 is provided with a plurality of installation holes that communicate with each other on the upper and lower sides. A connecting bearing 5 is arranged inside the installation hole. The outer shaft sleeve of the connecting bearing 5 is fixedly connected to the inner wall of the installation hole. The outer shaft sleeve of the connecting bearing 5 is fixedly connected to a holding bottom plate 6. A middle-layer support 7 is fixedly connected to the top outer wall of the holding bottom plate 6. Outer-layer supports 9 are arranged on both sides of the middle-layer support 7. A limiting insertion plate 8 is movably sleeved on the outer wall of the outer-layer support 9. One side outer wall of the limiting insertion plate 8 is slidably connected to one side outer wall of the middle-layer support 7. An arc-shaped groove 10 is opened on the top outer wall of the middle-layer support 7. The top outer wall of the arc-shaped groove 10 is aligned with the bottom outer wall of the chamfering cutter head 3. The top inclined support opening of the limiting insertion plate 8 is movably attached to one side outer wall of the bottom of the chamfering cutter head 3. The chamfering cutter head 3 is made of cemented carbide material, and the limiting insertion plate 8 is made of magnet material. The limiting insertion plate 8 and the chamfering cutter head 3 are magnetically attracted to each other.

[0041] In the present invention, when the chamfering cutter head 3 needs to be repaired or the model needs to be replaced, the chamfering cutter head 3 that rotates slowly and decelerates will gradually longitudinally fit onto the arc-shaped groove 10 under the drive of the displacement motor. The special arc shape of the arc-shaped groove 10 can meet the free rotation of the bottom of the chamfering cutter head 3. When the chamfering cutter head 3 still has a certain rotational speed at this time, the rapid movement of the chamfering cutter head 3 cannot generate sufficient magnetic suction force on the limiting insertion plate 8. When the chamfering cutter head 3 completely decelerates and slowly rotates until the bottom inclined surface of the chamfering cutter head 3 is parallel to the top inclined surface of the limiting insertion plate 8, the magnetic suction force between the two is maximized. At this time, the limiting insertion plate 8 will be magnetically adsorbed and move longitudinally upward, fitting onto the bottom outer wall of the chamfering cutter head 3, and combining with the middle-layer support 7 to form a complete base to hold the chamfering cutter head 3 and fix the chamfering cutter head 3. Through this combination, the rotation angle of the chamfering cutter head 3 can be captured and fixed in real time, without deliberately controlling and adjusting the rotation of the chamfering cutter head 3, without the need for staff to adjust the orientation, and it can be automatically disassembled, thus facilitating the repair or model replacement of the chamfering cutter head 3.

[0042] Embodiment 2. On the basis of Embodiment 1, a first reciprocating motor 11 is arranged directly below the mounting frame 4. The bottom outer wall of the first reciprocating motor 11 is fixedly connected to the top outer wall of the maintenance area platform. A connecting rod 12 is fixedly connected to the axis of the first reciprocating motor 11. A support plate 13 is fixedly connected to the top outer wall of the connecting rod 12. The top outer wall of the support plate 13 is movably attached to the bottom outer wall of the holding bottom plate 6. An infrared laser calibration probe 46 is fixedly installed on the inner wall of the mounting frame 4. Two second reciprocating motors 17 are fixedly installed on the top outer wall of the maintenance area platform. A threaded rod 16 is fixedly connected to the axis position of the second reciprocating motor 17. Threaded grooves 15 communicating at both ends are formed on the outer walls of both sides of the holding machine tool 14. The inner wall of the threaded groove 15 is threadedly connected to the outer wall of the threaded rod 16. The outer walls of the two threaded rods 16 away from the second reciprocating motor 17 are rotatably connected to the same anti-disengagement plate 18.

[0043] In the present invention, the first reciprocating motor 11 drives the support plate 13 to rotate. When the chamfering cutter head 3 still has the power to rotate on the limit insertion plate 8, it drives the chamfering cutter head 3 to deflect and then stop. This is conducive to the infrared laser calibration probe 46 comparing the infrared light cross-sectional width of the chamfering cutter head 3, thereby monitoring the deflection degree of the chamfering cutter head 3 in real time. The rotation of the support plate 13 drives the limit insertion plate 8 and the chamfering cutter head 3 to rotate back, and the chamfering cutter head 3 is adjusted back to the horizontal original position, which facilitates the maintenance or model replacement of the chamfering cutter head 3. When the chamfering cutter head 3 is disassembled and separated from the cutting drill rod 2, the second reciprocating motor 17 operates to drive the holding machine tool 14 to move horizontally. In the present invention, replacement cutter heads are placed on the holding bottom plates 6 at other positions. The holding bottom plates 6 at other positions are displaced to directly below the cutting drill rod 2 for convenient replacement. The central control platform 47 establishes a signal transmission channel with all the motors in the present invention.

[0044] Embodiment 3. On the basis of Embodiment 1, two mounting cavities 50 are provided on the outer wall of the top of the chamfering cutter head 3. The inner wall of the mounting cavity 50 is provided with a first helical gear 21. A limit screw 20 is fixedly connected to the outer wall of one side of the first helical gear 21. Front-end communication grooves 19 communicating with the two mounting cavities 50 are respectively provided on the outer walls of both sides of the chamfering cutter head 3. The inner wall of the front-end communication groove 19 is threadedly connected to the outer wall of the limit screw 20. A rear-end communication groove 51 corresponding to the position of the front-end communication groove 19 is provided on the inner wall of the bottom angle of the cutting drill rod 2. The inner wall of the rear-end communication groove 51 is threadedly connected to the outer wall of the limit screw 20. Mounting slide rails 26 are fixedly installed on both sides of the outer wall of the top of the mounting frame 4. A linear drive motor 27 is fixedly connected to the outer wall of the top of the mounting slide rail 26. A telescopic rod 28 is fixedly connected to the axis of the linear drive motor 27. One end of the telescopic rod 28 away from the linear drive motor 27 is fixedly connected to a cage 29. A turntable one 30 and a turntable two 31 are respectively rotatably connected to both ends of the inner wall of the cage 29. The outer walls of the turntable one 30 and the turntable two 31 are movably connected by the same connecting belt 52. A third reciprocating motor 32 is fixedly connected to the outer wall of the top of the turntable two 31. The axis of the third reciprocating motor 32 passes through the outer wall of the top of the cage 29 and is fixedly connected to the outer wall of the top of the turntable two 31. A second helical gear 33 is fixedly connected to the outer wall of the top of the turntable one 30. The outer wall of the second helical gear 33 is meshed with the outer wall of the first helical gear 21.

[0045] In the present invention, the chamfering cutter head 3 is threadedly fixed to the inner wall of the bottom of the cutting drill rod 2 through the limit screw 20. By starting the linear drive motor 27 to drive the telescopic rod 28 to extend, the second helical gear 33 at one end of the cage 29 extends into the mounting cavity 50, so that the second helical gear 33 is gradually meshed with the first helical gear 21. At the same time, the third reciprocating motor 32 is started to drive the second helical gear 33 to rotate synchronously through the connecting belt 52. At this time, the second helical gear 33 will drive the first helical gear 21 to rotate meshingly, so that the limit screw 20 rotates back and disengages from the front-end communication groove 19, completing the disassembly of the cutting drill rod 2 and the chamfering cutter head 3, thereby facilitating the overhaul or model replacement of the chamfering cutter head 3.

[0046] Embodiment 4. On the basis of Embodiment 3, opening grooves 23 communicating with the two mounting cavities 50 are respectively provided on the outer walls of both sides of the chamfering cutter head 3. A limit connecting shaft 48 is rotatably connected to the inner wall of the bottom of the mounting cavity 50. An arc baffle 24 is fixedly connected to the outer wall of one side of the limit connecting shaft 48. The outer wall of the arc baffle 24 is movably attached to the inner wall of the mounting cavity 50. An arc tooth groove 25 is provided on the outer wall of one side of the arc baffle 24. The arc tooth groove 25 is threadedly connected to the second helical gear 33. A limit magnet 44 is fixedly installed on the inner wall of one side of the mounting cavity 50. The limit magnet 44 is magnetically connected to the arc baffle 24. An eccentric counterweight 45 is fixedly connected to the inner wall of one side of the arc baffle 24. A threaded guiding groove 35 is provided on the inner wall of the mounting cavity 50.

[0047] In the present invention, an opening groove 23 is provided for the cage 29 to pass through. When the chamfering cutter head 3 is in use, the chamfering cutter head 3 will generate centrifugal force through high-speed rotation. This magnetic centrifugal force will further swing the arc baffle 24, causing the arc baffle 24 to shift with the limit connecting shaft 48 as the axis. At this time, the eccentric counterweight 45 will be forced to abut against the position of the limit magnetic block 44, completely blocking the opening groove 23, thereby preventing iron filings from entering during the cutting process of the chamfering cutter head 3. By setting the threaded guiding groove 35, the friction force on the arc baffle 24 can be reduced, ensuring the offset of the arc baffle 24. By installing the eccentric counterweight 45 on the outer wall of the arc baffle 24, the eccentric counterweight 45 becomes a component with asymmetric center of gravity, thus ensuring that the chamfering cutter head 3 generates an offset during rotation. At the same time, the arc baffle 24 is resisted and limited by the limit magnetic block 44, and a magnetic suction force is generated, so that the arc baffle 24 will not rebound due to inertia when the chamfering cutter head 3 decelerates and stops rotating, thereby ensuring that the opening groove 23 is completely blocked and does not affect the daily use of the chamfering cutter head 3.

[0048] When the chamfering cutter head 3 needs to be disassembled for maintenance or model replacement, the cage 29 enters the installation cavity 50 through the opening groove 23. When the second helical gear 33 rotates, one side of the teeth will gradually press against the position of the arc tooth groove 25 to generate meshing. At this time, the rotation of the second helical gear 33 will drive the arc baffle 24 to shift and rotate back, causing the arc baffle 24 to disengage from the opening groove 23, facilitating the combination disassembly of the second helical gear 33 into the installation cavity 50.

[0049] Embodiment 5, on the basis of Embodiment 3, a protective cover 49 is fixedly installed on the top outer wall of the installation cavity 50 where the chamfering cutter head 3 is located. Through holes are provided in 21 and 20, and a limit slide rod 22 is slidably connected to the inner wall of the through hole. A connecting hinge 34 is fixedly installed on the middle outer wall of the limit slide rod 22, and the limit slide rod 22 is bent into two sections through the connecting hinge 34.

[0050] In the present invention, the disassembly of the protective cover 49 facilitates the maintenance of the combined components in the installation cavity 50 by the staff. The connecting hinge 34 can satisfy the rotation of the upward inclination angle. The limit screw 20 that disengages from the cutting drill rod 2 will be suspended on the limit slide rod 22 through displacement. By bending the connecting hinge 34, the first helical gear 21 can be taken out from above the installation cavity 50 for maintenance. When reinstalling, no calibration is required, and the limit screw 20 can be rotated back into the front connecting groove 19 to complete the combined installation through the rotation of the second helical gear 33.

[0051] Embodiment 6, on the basis of embodiment 4, a liquid-carrying channel 36 connected to the bottom outer wall is fixedly installed inside the cutting drill rod 2, a calibration plug 38 is fixedly connected to the bottom outer wall of the liquid-carrying channel 36, a calibration slot 39 is opened on the top outer wall of the chamfering cutter head 3, the outer wall of the calibration plug 38 is movably plugged with the inner wall of the calibration slot 39, the outer walls of both sides of the calibration plug 38 are fixedly connected to rubber air bags 40, and a nozzle 41 is fixedly installed on the upper end of the outer wall of one side of the rubber air bag 40, and the nozzle 41 is The installation is inclined, and the inner wall of the installation cavity 50 is fixedly connected with a spring pressure rod 42, and the outer wall of the spring pressure rod 42 is spring-sleeved with an adjusting plate 43, and the outer wall of the bottom side of the adjusting plate 43 is movably fitted with the outer wall of one side of the arc baffle 24, and the outer wall of the top side of the adjusting plate 43 is movably fitted with the lower end of the outer wall of one side of the rubber airbag 40, and the outer wall of one side of the cutting drill rod 2 is provided with an addition hole connected to the liquid carrier channel 36, and the inner wall of the addition hole is movably connected with a leak-proof cover 37, and the leak-proof cover 37 is provided with a ventilation valve hole.

[0052] In the present invention, the staff stores a small amount of lubricating oil in the liquid-carrying channel 36 through the adding hole. When the arc baffle 24 rotates, the outer wall of one side of the arc baffle 24 will resist the bottom outer wall of the adjusting plate 43, driving the adjusting plate 43 to slide and deflect on the outer wall of the spring pressing rod 42. At this time, the outer wall of the top side of the adjusting plate 43 will squeeze the outer wall of the rubber airbag 40, so that a small amount of lubricating oil is squeezed out from the nozzle 41. By providing a threaded guide groove 35 on the inner wall of the installation cavity 50, the lubricating liquid can flow along the threaded groove, providing the installation cavity 50 with a lubricating oil. Lubrication further ensures the offset of the arc baffle 24. At the same time, the lubricating liquid will flow through the thread to the front end connecting groove 19 obliquely below, thereby ensuring the lubrication of the front end connecting groove 19 and the limit screw 20. In the present invention, the rubber airbag 40 is small in size and the nozzle 41 has a fine opening, which can only ensure the flow of a small amount of lubricating oil. The combined component will only be used when disassembling the chamfering cutter head 3 and is not frequently used. Multiple sets of replacement tools are evenly distributed in use, so excessive lubricating oil will not accumulate in the installation cavity 50, which will not affect the normal use of the chamfering cutter head 3.

[0053] The working principle and usage process of the present invention: In the present invention, when the chamfering cutter head 3 needs to be repaired or replaced, the chamfering cutter head 3 that rotates slowly and decelerates will gradually longitudinally fit onto the arc groove 10 through the drive of the displacement motor. The special arc shape of the arc groove 10 can satisfy the free rotation of the bottom of the chamfering cutter head 3. When the chamfering cutter head 3 still has a certain rotation speed at this time, the rapid movement of the chamfering cutter head 3 cannot generate sufficient magnetic attraction for the limiting plug plate 8. When the chamfering cutter head 3 is completely decelerated and slowly rotated until the bottom oblique side surface of the chamfering cutter head 3 is parallel to the top oblique side surface of the limiting plug plate 8, the magnetic attraction between the two is maximized. At this time, the limiting plug plate 8 will be magnetically adsorbed and moved upward longitudinally, fit onto the bottom outer wall of the chamfering cutter head 3, and be assembled with the middle layer to form a complete bracket 7. The whole base supports the chamfering cutter head 3 to fix the chamfering cutter head 3. Through this combination, the rotation angle of the chamfering cutter head 3 can be captured and fixed in real time, and there is no need to deliberately manipulate and adjust the rotation of the chamfering cutter head 3, thereby facilitating the inspection and maintenance or model replacement of the chamfering cutter head 3. In the present invention, the first reciprocating motor 11 drives the support plate 13 to rotate. When the chamfering cutter head 3 is kept on the limit plug plate 8 and there is still spare power to rotate, the chamfering cutter head 3 is driven to deviate and stop slowly, which is beneficial for the infrared laser calibration probe 46 to compare the infrared light cross-sectional width of the chamfering cutter head 3, thereby monitoring the deviation degree of the chamfering cutter head 3 in real time, and the limit plug plate 8 and the chamfering cutter head 3 are driven to rotate through the rotation of the support plate 13, and the chamfering cutter head 3 is adjusted back to the horizontal original position, thereby facilitating the inspection and maintenance or model replacement of the chamfering cutter head 3. After the chamfering cutter head 3 is disassembled and separated from the cutting drill rod 2, the operation of the second reciprocating motor 17 drives the machine tool 14 to move horizontally. The retaining base plate 6 at other positions in the present invention is placed with a replacement cutter head. The retaining base plate 6 at other positions is moved to the bottom of the cutting drill rod 2 for easy replacement. The central control platform 47 and all motors in the present invention establish a signal transmission channel. In the present invention, the chamfering cutter head 3 is threadedly fixed to the bottom inner wall of the cutting drill rod 2 by the limit screw 20, and the telescopic rod 28 is extended by starting the linear drive motor 27, so that the second bevel gear 33 at one end of the retaining frame 29 extends into the installation cavity 50, so that the second bevel gear 33 is gradually meshed with the first bevel gear 21. At the same time, the third reciprocating motor 32 is started to connect The connecting belt 52 drives the second bevel gear 33 to rotate synchronously. At this time, the second bevel gear 33 drives the first bevel gear 21 to rotate in meshing, so that the limit screw 20 rotates out of the front connecting groove 19, and the disassembly of the cutting drill rod 2 and the chamfering cutter head 3 is completed, thereby facilitating the inspection or model replacement of the chamfering cutter head 3. In the present invention, an open groove 23 is provided for the retaining frame 29 to pass through. When the chamfering cutter head 3 is in use, the chamfering cutter head 3 will generate centrifugal force through high-speed rotation. This magnetic centrifugal force will further swing the arc baffle 24, causing the arc baffle 24 to deviate with the limit connecting shaft 48 as the axis. At this time, the eccentric counterweight block 45 will be forced to press against the position of the limit magnetic block 44, completely blocking the open groove 23, thereby preventing the chamfering cutter head 3 from entering iron filings during cutting.By setting the threaded guide groove 35, the friction force on the arc baffle 24 can be reduced to ensure the offset of the arc baffle 24. By installing an eccentric counterweight 45 on the outer wall of the arc baffle 24, the eccentric counterweight 45 becomes a component with asymmetric center of gravity, so as to ensure that the chamfering cutter head 3 generates an offset during rotation. At the same time, the arc baffle 24 is resisted and limited by the limit magnet 44, and a magnetic suction force is generated, so that the arc baffle 24 will not rebound due to inertia when the chamfering cutter head 3 decelerates and stops rotating, thus ensuring that the opening groove 23 is completely blocked without affecting the daily use of the chamfering cutter head 3. When the chamfering cutter head 3 needs to be disassembled for maintenance or model replacement, the cage 29 enters the installation cavity 50 through the opening groove 23. When the second helical gear 33 rotates, one side of the teeth will gradually press against the arc tooth groove 25 to generate meshing. At this time, the rotation of the second helical gear 33 will drive the arc baffle 24 to offset and rotate, so that the arc baffle 24 disengages from the opening groove 23, facilitating the combination disassembly of the second helical gear 33 into the installation cavity 50. In the present invention, the disassembly of the protective cover 49 facilitates the staff to repair the combined components in the installation cavity 50. The connecting hinge 34 can meet the rotation of the upward inclination angle. The limit screw 20 disengaged from the cutting drill rod 2 will be suspended on the limit slide rod 22 through displacement. By bending the connecting hinge 34, the first helical gear 21 can be taken out from above the installation cavity 50 for maintenance. When reinstalling, there is no need to calibrate, and the limit screw 20 can be rotated back into the front end communication groove 19 to complete the installation through the rotation of the second helical gear 33. In the present invention, the staff stores a small amount of lubricating oil in the liquid-carrying channel 36 through the adding hole. When the arc baffle 24 rotates, one side outer wall of the arc baffle 24 will resist the bottom outer wall of the adjusting plate 43 to drive the adjusting plate 43 to slide and deflect on the outer wall of the spring pressing rod 42. At this time, the top side outer wall of the adjusting plate 43 will squeeze the outer wall of the rubber airbag 40, so that a small amount of lubricating oil is extruded from the nozzle 41. By opening the threaded guide groove 35 on the inner wall of the installation cavity 50, the lubricating liquid can flow along the threaded pattern, providing lubrication for the installation cavity 50 and further ensuring the offset of the arc baffle 24. At the same time, the lubricating liquid will flow in a threaded manner to the front end communication groove 19 obliquely below, thus ensuring the lubrication of the front end communication groove 19 and the limit screw 20. In the present invention, the rubber airbag 40 is small in volume and the nozzle 41 has a fine opening, which can only ensure the flow of a small amount of lubricating oil, and this combined component is only used when disassembling the chamfering cutter head 3, and it is not frequently used. Moreover, multiple sets of replacement tools are evenly used and distributed, so there will be no excessive accumulation of lubricating oil in the installation cavity 50, which does not affect the normal use of the chamfering cutter head 3.,
