[0002] A numerically controlled turning and milling machine is a device that uses turning and milling tools to machine workpieces, and it requires a multi-station tool turret to support multiple tools for rapid machining work. Conventional multi-station tool turrets generally use a rotation drive method of gears and gear discs to rotate and change tools for machining work. When machining, workpiece debris will be generated by the tools, and the machining debris is easily attached to the surface of the tools, resulting in a decline in cutting performance, and there is a lack of an anti-rust protection mechanism, shortening the service life of the tools. Therefore, there is an urgent need for a six-station tool turret that integrates tool maintenance.

[0022] In the actual application process of this embodiment: The staff can install six cutting tools at the end of the tool holder 6 as needed, and use the fixing components to fix the housing 1 on the working station of the numerically controlled turning and milling machine. The numerically controlled turning and milling machine will control the operation of the motor 8 according to the actual processing requirements, so that the electrode drives the commutator 9 with the support of the housing 1 at the driving end, so that the commutator 9 drives the gear 10 to rotate, so that the gear 10 drives the tooth disc 3 to rotate with the support of the housing 1. At the same time, the tooth disc 3 will drive the rotating base 2, the turntable 4, the rotating column 5, the clamping column 17 and the tool holder 6 to rotate together, thereby adjusting the positions of the cutting tools installed on the tool holder 6. The clamping column 17 will rotate and insert into the inner side of the clamping column 17 along with the rotating base 2. Subsequently, the motor 11 can be controlled to start, so that the motor 11 drives the first pulley 12 to rotate with the driving end, so that the first pulley 12 drives the second pulley 15 to rotate together through the synchronous belt 16, so that the second pulley 15 drives the clamping column 17 to rotate together with the support of the support sleeve 14, so that the two clamping columns 17 drive the two rotating columns 5 to rotate together through the two plugs 7, so that the rotating column 5 drives the two cutting tools to rotate together through the tool holder 6, so that the cutting tools can perform processing work.

[0023] As a preferred embodiment of the present invention, the fixing assembly includes: A cylinder 24, fixed inside the housing 1; A push head 25, one end of which is fixed to one end of the cylinder 24; A bolt 26, fixed to the other end of the push head 25 and arranged in the direction away from the rotating base 2 of the tooth disc 3; Six jacks 62 are evenly opened at one end of the tooth disc 3.

[0024] Specifically, the housing 1 can provide a stable support for the cylinder 24, the cylinder 24 can provide a support for the push head 25, the push head 25 can provide a stable support for the bolt 26, the tooth disc 3 can provide a space for opening the jack 62, and after the bolt 26 is inserted into the jack 62, the tooth disc 3 will be fixed.

[0025] The driving and contacting assembly includes: An air cylinder 27, fixed to the other end of the push head 25 and located outside the bolt 26; A support plate 28, fixed to one end of the push head 25 and located above the cylinder 24; An airbag 29, fixed to the support plate 28; A second magnet 30, fixed to the airbag 29 and connected to the support plate 28 in a lifting and guiding manner; An air pipe 65, passing through the support plate 28 and the push head 25, one end of which is communicated with the airbag 29 and the other end of which is communicated with the air cylinder 27.

[0026] Specifically, a guide ring 31 is fixed to the outside of the second magnet 30; A guide plate 32 is fixed to the support plate 28 and is connected to the guide ring 31 in a guiding manner.

[0027] The push head 25 can provide stable support for the air cylinder 27. Air is stored inside the air cylinder 27. The push head 25 can provide stable support for the support plate 28. The support plate 28 can provide support for the airbag 29. The air pipe 65 can connect the airbag 29 and the air cylinder 27 to each other. The airbag 29 can provide stable support for the second magnet 30, and the positive pole of the second magnet 30 faces upward.

[0028] During the actual application of this embodiment, after the motor 8 starts to rotate to adjust the position of the tool, it is necessary to control the air cylinder 24 to extend, so that the air cylinder 24 uses its telescopic end to push the push head 25 closer to the position of the gear disk 3, and the push head 25 pushes the pin 26 into the jack 62 at the corresponding position, so that the pin 26 can cooperate with the jack 62 under the support of the air cylinder 24 to position the gear disk 3, preventing the gear disk 3 from shifting when the tool holder 6 and the tool rotate. At the same time, the push head 25 will drive the support plate 28, the air pipe 65 and the air cylinder 27 to move together. At the same time, the support plate 28 will drive the second magnet 30 to move together through the airbag 29. And during the process of the pin 26 being inserted into the jack 62, it cooperates with the gear disk 3 to squeeze the air cylinder 27, so that the air in the air cylinder 27 is squeezed into the air pipe 65. The air will fill the inside of the airbag 29 along the air pipe 65. Then, under the support of the support plate 28 and the guiding action of the guide ring 31 and the guide plate 32, the airbag 29 expands upward, so that the airbag 29 can push the second magnet 30 to move upward. At the same time, the guide plate 32 will drive the infrared sensor 33 to move closer to the gear disk 3 along with the support plate 28, so that the infrared sensor 33 senses that the distance from the gear disk 3 becomes closer, and then triggers the multi-stage electric rod 43 to contract.

[0029] As a preferred embodiment of the present invention, the storage and injection assembly includes: A support frame 20, fixed on the machine shell 1; A rocker arm 22, movably penetrating through the machine shell 1 and rotatably connected to the support frame 20; A first magnet 23, fixed at one end of the rocker arm 22 and staggered with the second magnet 30; An arc-shaped cylinder 59, fixed on the outside of the rocker arm 22 and inclined downward; A rubber tube 61, penetrating through the rocker arm 22 in a Z shape, with one end communicating with the arc-shaped cylinder 59 and the other end extending to the outside of the gear disk 3.

[0030] Specifically, a rotating rod 21 is penetrated inside the support frame 20. A rocker 34 is rotatably connected to the outside of the rotating rod 21. The rocker 34 is beside the rocker arm 22, and the rocker 34 is fixedly connected to the support 35. The rotating rod 21 is rotatably connected to the rocker arm 22. A through hole 19 is penetrated through the machine shell 1, and the through hole 19 is located outside the rocker arm 22. A threaded cover 60 is penetrated and threadedly connected to the arc-shaped cylinder 59.

[0031] The support frame 20 can stably support the rotating rod 21 under the support of the housing 1. The rotating rod 21 can provide rotational support for the rocker arm 22 and the rocker 34. The rocker arm 22 can stably support the first magnet 23. The positive pole of the first magnet 23 faces downward. The rocker arm 22 can stably support the arc cylinder 59. The arc cylinder 59 can support the rubber tube 61, and the arc cylinder 59 can provide a storage space for the lubricating oil. The rubber tube 61 can provide a flow channel and a guide for the lubricating oil, so that the lubricating oil can flow along the rubber tube 61 to the outside of the gear disk 3. The housing 1 can support the rocker arm 22.

[0032] The pressing and closing assembly includes: A cavity 47 is opened inside the rocker arm 22 and penetrates through one side of the rocker arm 22, and is located outside one end of the rubber tube 61. An inclined plate 38 is movably arranged in the cavity 47. A tapered plate 64 is fixed to the bottom surface of the inclined plate 38 through a connecting member and corresponds to the position of the rubber tube 61. A triggering part is arranged inside the housing 1 and is connected to the support plate 28 and the rocker arm 22.

[0033] Specifically, a guide rod 39 is fixed to the outside of the rocker arm 22. A guide plate 40 is fixed to one end of the inclined plate 38 and is sleeved outside the guide rod 39. A follower frame 63 has one end fixed to the inclined plate 38 and the other end fixedly connected to the tapered plate 64.

[0034] The rocker arm 22 can provide a space for opening the cavity 47, and the rocker arm 22 can stably support the guide rod 39. The guide rod 39 can provide support and guidance for the guide plate 40, and the guide plate 40 can support the inclined plate 38. The inclined plate 38 can stably support the tapered plate 64 through the follower frame 63. One end of the tapered plate 64 is relatively sharp and can squeeze the rubber tube 61 to deform under the action of an external force, thereby closing the channel of the rubber tube 61.

[0035] The triggering part includes: An infrared sensor 33 is fixed above the support plate 28 and is located on one side of the second magnet 30. A multi-stage electric rod 43 is arranged in the cavity 47, and its fixed end is fixedly connected to the rocker arm 22. A baffle 41 is fixed to the telescopic end of the multi-stage electric rod 43 and abuts against one end of the inclined plate 38. A sliding ball 42 is fixed to the surface of the baffle 41 close to the rubber tube 61. Specifically, the infrared sensor 33 is fixedly connected to the guide plate 32. The guide ring 31 is located beside the infrared sensor 33. The infrared sensor 33 can detect the real-time distance and trigger the contraction of the multi-stage electric rod 43 when the distance between it and the gear disk 3 becomes closer, and trigger the extension of the multi-stage electric rod 43 when the distance between it and the gear disk 3 moves away from the closer position. The multi-stage electric rod 43 can provide a stable support for the baffle 41 under the support of the rocker arm 22. The baffle 41 can provide a resisting effect for the inclined plate 38 and can stably support the sliding ball 42. The inclined plate 38 has an inclination angle. The horizontal line of the arc barrel 59 is lower than the horizontal line of the rubber tube 61, as Figure 10 shown.

[0036] In the actual application process of this embodiment, the inclined plate 38 can provide a resisting and supporting effect for the arc plate 37 under the support of the baffle 41. The rocker arm 22 can naturally hang on the machine housing 1 under the support of the rotating rod 21 by using the first magnet 23 and its own gravity. Then, under the resistance of the inclined plate 38 and the baffle 41, the arc plate 37 provides support for the support 35 and the sleeve 48 through the connecting plate 36, so that the sleeve 48 and its inner components are supported and stored together at the position as Figure 2 shown, thereby preventing the rotation movement of the tool along with the turntable 4 from being affected by the arrangement of the sleeve 48 and its inner components. The arc barrel 59 is made of a transparent material, which is convenient for the staff to observe the liquid level inside.

[0037] The staff can rotate the threaded cap 60 as needed, remove the threaded cap 60 from the arc barrel 59 by using the thread action, open the opening of the arc barrel 59, and then inject the lubricating liquid into the arc barrel 59 for storage.

[0038] During the process that the support plate 28 drives the second magnet 30 to move together towards the direction close to the gear disk 3 through the air bag 29, the second magnet 30 will gradually move below the first magnet 23, so that the second magnet 30 uses the principle of like poles repelling each other to push the first magnet 23 upward. Then, the first magnet 23 drives the rocker arm 22 to rotate clockwise with the rotating rod 21 as the center under the support of the support frame 20. When the air bag 29 pushes the second magnet 30 to move upward, it will further shorten the distance between the second magnet 30 and the first magnet 23. Then, the second magnet 30 uses the magnetic force to further push the first magnet 23, so that the first magnet 23 drives the rocker arm 22 to continue to rotate clockwise with the rotating rod 21 as the center under the support of the support frame 20. Thus, the rocker arm 22 can rotate ten degrees clockwise with the rotating rod 21 as the center from its original position. During the rotation process, the resisting force received by the arc plate 37 will disappear. Then, the arc plate 37, the connecting plate 36, the support 35, the rocker 34, the sleeve 48 and all the components arranged inside it will rotate ten degrees clockwise with the rotating rod 21 as the center, as Figure 12As shown, the position of the preliminary adjustment sleeve 48 is realized. At the same time, during the rotation of the rocker arm 22, the arc barrel 59 and the rubber hose 61 will be driven to rotate together, so that the horizontal line of the rubber hose 61 moves below the horizontal line of the arc barrel 59 during the rotation. Then, the lubricating oil stored in the arc barrel 59 can flow into the inner side of the rubber hose 61 under the action of gravity, and along the rubber hose 61 through the rocker arm 22 under the action of the inclination angle and gravity and is discharged onto the toothed disc 3, so that the lubricating oil can be filled onto the toothed disc 3, and the lubricating oil can contact the gear 10 during the rotation of the toothed disc 3, which is convenient for providing lubrication between the gear 10 and the toothed disc 3 and reducing the labor maintenance cost.

[0039] In another preferred embodiment of the present invention, the rotation support assembly includes: A support 35, rotatably connected to the support frame 20 through a connecting member; An arc plate 37, fixedly connected to the support 35 through a connecting member, and located at the other end of the rocker arm 22, and meanderingly abuts against the other end of the inclined plate 38; A sleeve 48, fixed on the outer side of the support 35 and located obliquely above the tool holder 6.

[0040] Specifically, a connecting plate 36 is fixed at one end of the support 35 close to the arc plate 37. The connecting plate 36 is fixedly connected to the arc plate 37. The support 35 can provide a stable support for the connecting plate 36, the connecting plate 36 can provide a support for the arc plate 37, and the inclined plate 38 can provide a resisting support for the arc plate 37, so that the arc plate 37 can support the support 35 through the connecting plate 36, and the support 35 can provide a support for the sleeve 48.

[0041] The maintenance component includes: A rotating sleeve 49, arranged inside the sleeve 48; A ring brush 50, fixed on the inner wall of the rotating sleeve 49; A capsule 51, symmetrically fixed on the inner wall of the rotating sleeve 49, and recessed towards the outside of the rotating sleeve 49, and located above the ring brush 50; A sponge 52, fixed at the position where the capsule 51 is recessed towards the outside; A transfer part, penetrating through the capsule 51 and the sleeve 48; A pressing part, arranged in the cavity 47 and connected to the baffle 41.

[0042] Specifically, the sleeve 48 can provide a moving space for the rotating sleeve 49 and can provide a stable support for the reciprocating push rod 56. The rotating sleeve 49 can provide a stable support for the ring brush 50 and the capsule 51. The capsule 51 has elasticity and can be deformed under the action of an external force and will rebound when the external force disappears. And it can provide a storage space for the antirust oil. The capsule 51 can provide a space for opening the perforation 53. The capsule 51 can stably support the sponge 52. The sponge 52 has adsorbability and can provide a penetration space for the antirust oil, and the sponge 52 has elasticity.

[0043] The pouring part includes: The perforation 53 is opened through the capsule 51 and is located at a position recessed outwardly; The plug 54 is arranged through one end of the capsule 51; The through groove 57 is opened through one end of the sleeve 48; The reciprocating push rod 56 has a fixed end fixed outside the sleeve 48, and the telescopic end passes through the through groove 57 through the connecting part and is fixedly connected to the rotating sleeve 49.

[0044] Specifically, the perforation 53 can provide a through channel for the rust preventive oil, so that the rust preventive oil can pass through the perforation 53 under the action of extrusion and enter the sponge 52. The capsule 51 can provide a stable support for the plug 54. A pull ring 55 is fixed on the outside of the plug 54. The sleeve 48 can stably support the reciprocating push rod 56, and the sleeve 48 can provide a space for opening the through groove 57. A connecting block 58 is fixed at the telescopic end of the reciprocating push rod 56. The connecting block 58 passes through the through groove 57 and is fixedly connected to the rotating sleeve 49. The through groove 57 can provide a moving space for the connecting block 58.

[0045] The pressing part includes: The pressure sensor 44 is arranged in the cavity 47, is fixedly connected to the rocker arm 22, and is located on one side of the multi-stage electric rod 43; The spring 45 has one end fixed on the baffle 41 and corresponds to the position of the pressure sensor 44; The pressing head 46 is fixed at the other end of the spring 45; Specifically, the pressure sensor 44 can sense the pressure and can trigger the operation of the reciprocating push rod 56 after sensing the pressure, so that the reciprocating push rod 56 pushes the arc barrel 59 to reciprocate through the connecting block 58. The baffle 41 can provide support for the spring 45 under the support of the multi-stage telescopic rod. The spring 45 can stably support the pressing head 46 and can deform under the action of an external force and will rebound after the external force disappears, and can prevent the pressing head 46 from excessively pressing the pressure sensor 44 by its own elastic force.

[0046] In the actual application process of this embodiment, the staff needs to pull out the plug 54 from the capsule 51 through the pull ring 55, open an opening on the capsule 51, and then inject the rust preventive oil into the capsule 51 for storage through the opening. And the capsule 51 is made of a transparent material, which is convenient for observing the liquid level.

[0047] When the multi-stage electric rod 43 is triggered to contract, it will drive the baffle 41 to move towards the pressure sensor 44 together, thereby separating the baffle 41 from the inclined plate 38 and releasing the blocking effect on the inclined plate 38. As a result, the arc plate 37, the connecting plate 36, and the support 35 will drive the rocker 34 to rotate clockwise around the rotating rod 21 under the action of gravity. Then, the inclined plate 38 can be pushed into the cavity 47 by the weights of the arc plate 37, the connecting plate 36, the support 35, the sleeve 48 and its inner components. At the same time, the inclined plate 38 will drive the guide plate 40 to move along the guide rod 39 by using external force, providing a moving guiding effect for the inclined plate 38. Then, the inclined plate 38 drives the conical plate 64 to move together through the follower frame 63. Under the action of the weights of the arc plate 37, the connecting plate 36, the support 35, the sleeve 48 and its inner components, the conical plate 64 squeezes and closes the channel of the rubber tube 61 to block the continuous outflow of the lubricating oil and control the discharge amount of the lubricating oil. At this time, the sleeve 48 will drive the rotating sleeve 49, the ring brush 50, the capsule 51 and the sponge 52 to be sleeved together outside the tool located directly above the turntable 4. Under the resistance of the tool, the sponge 52 and the capsule 51 are squeezed and deformed. The sponge 52 elastically adheres to the tool under the support of the capsule 51. When the tool squeezes the capsule 51 to deform, the space inside the capsule 51 will shrink. Then, part of the rust preventive oil is forced to pass through the perforation 53 and be injected into the sponge 52 and penetrate the sponge 52. Subsequently, after the multi-stage electric rod 43 is completely contracted, it will drive the pressure head 46 to contact the pressure sensor 44 through the baffle 41 and the spring 45. Under the resistance of the pressure sensor 44, the spring 45 is squeezed to contract, and the reaction force of the spring 45 is used to apply pressure to the pressure sensor 44 through the pressure head 46. When the pressure sensor 44 senses the pressure, it triggers the start of the reciprocating push rod 56. The reciprocating push rod 56 pushes the rotating sleeve 49 to move up and down along the tool through the connecting block 58. At the same time, it is necessary to start the motor 11 to drive the rotating column 5 and the clamping column 17 to rotate, so that the clamping column 17 drives the two tool holders 6 located directly above and directly below the turntable 4 to rotate. During the reciprocating movement, the ring brush 50 can brush off the processing debris adhered to the tool surface, and the sponge 52 can cooperate with the rotation and reciprocating movement of the tool holder 6 to apply the absorbed rust preventive oil to the outer surface of the tool, thus facilitating the automatic maintenance of the tool and extending its service life.

[0048] When it is necessary to adjust the tool for processing, it is necessary to control the cylinder 24 to contract, so that the bolt 26 is pulled out of the jack 62. At the same time, the push head 25 will move away from the gear disk 3, releasing the extrusion on the air cylinder 27. The air cylinder 27 will then rebound and reset by using the rebound force. At the same time, the air filled in the air bag 29 is sucked out through the air pipe 65, thereby resetting the second magnet 30. At the same time, the infrared sensor 33 senses that the distance is far away, and then triggers the multi-stage electric rod 43 to extend. The multi-stage electric rod 43 pushes the baffle 41 to drive the sliding ball 42 to move towards the direction close to the rubber tube 61. Then the sliding ball 42 contacts the inclined surface of the inclined plate 38 moved into the cavity 47, and the sliding ball 42 uses the thrust of the multi-stage electric rod 43 and its own smooth surface to push the inclined plate 38. Under the action of external force and the inclination angle, the inclined plate 38 moves towards the direction close to the guide plate 40 by using the guiding action of the guide rod 39 and the guide plate 40. Then the inclined plate 38 is reset to the position as shown in Figure 13 the figure. At the same time, the inclined plate 38 will push the arc plate 37 during the reset process, so that the arc plate 37 drives the rocker 34 and the sleeve 48 to rotate counterclockwise and reset together with the connecting plate 36 and the support 35 with the rotating rod 21 as the center. And the rocker arm 22 will rotate counterclockwise and reset under the support of the rotating rod 21 by using gravity.

[0049] Working principle: The motor 8 drives the gear 10 to rotate through the commutator 9. The gear 10 meshes with the gear disk 3 to drive the turntable 4 to rotate. The turntable 4 drives the six rotating columns 5 to rotate synchronously, realizing the rapid switching and positioning of the six-station tool.

[0050] After the tool is positioned, the cylinder 24 pushes the bolt 26 to insert into the jack 62 of the gear disk 3 to fix the position of the gear disk 3, ensuring the processing stability; the air cylinder 27 is compressed to fill the air into the air bag 29 through the air pipe 65, triggering the second magnet 30 to rise, driving the first magnet 23 through magnetic repulsion, driving the rocker arm 22 to rotate. Through the rigid locking of the bolt 26 and the jack 62 of the gear disk 3, it is possible to avoid the tool deviation caused by the vibration during processing and maintenance, and improve the processing accuracy.

[0051] The rocker arm 22 is driven to rotate by magnetic force, driving the arc cylinder 59 to tilt. The lubricating oil flows to the surface of the gear disk 3 through the rubber tube 61 under the action of gravity, lubricating the meshing surface of the gear 10 and the gear disk 3. The pressing and closing assembly dynamically adjusts the opening and closing of the rubber tube 61 through the inclined plate 38 and the tapered plate 64, and combines with the multi-stage electric rod 43 to control the movement of the baffle 41 to control the injection amount of the lubricating oil. The magnet-triggered rotary injection mechanism realizes unattended lubrication and reduces the wear of the gear 10.

[0052] The sleeve 48 wraps the cutting tool under the action of gravity, and the ring brush 50 rotates to remove machining debris; the capsule 51 is deformed under pressure, and the rust preventive oil penetrates through the perforations 53 into the sponge 52 and evenly coats the surface of the cutting tool. After the pressure sensor 44 is triggered, the reciprocating push rod 56 drives the rotating sleeve 49 to move up and down, and combined with the rotation of the cutting tool, the full coverage coating of the rust preventive oil is realized. The rotating and maintaining mechanism automatically cleans and performs rust prevention treatment, reduces the frequency of cutting tool replacement, and the double protection of the ring brush 50 and the sponge 52 reduces the adhesion of metal debris, and the service life of the cutting tool is extended.

[0053] After the machining is completed, the cylinder 24 contracts and resets, the bolt 26 disengages from the gear disk 3, and the airbag 29 is depressurized to reset the second magnet 30; the multi-stage electric rod 43 extends to push the baffle 41 to reset, and the inclined plate 38 resets and drives the rotating and maintaining mechanism to retract, so as to avoid interfering with subsequent machining.

[0054] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
