[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0039] Reference Figure 1- Figure 3 , which is the first embodiment of the present invention, provides a self-cleaning dual-servo turret CNC lathe, including a body 1,

[0040] The spindle unit 2 includes a headstock 21 disposed on the vehicle body 1 and a spindle 22 disposed at the output end of the headstock 21;

[0041] The turning unit 4 includes a CNC slide 41 provided on both sides of the spindle 22 and a servo turret 42 provided at the moving end of the CNC slide 41;

[0042] The storage unit 5 includes a storage box 51 arranged below one end of the main shaft 22, a fixed seat 52 arranged in the inner cavity of the storage box 51, a lifting block 53 slidably arranged in the inner cavity of the fixed seat 52, a mounting seat 55 arranged at the top of the lifting block 53, a first spring 54 arranged between the mounting seat 55 and the fixed seat 52, and a wiping sponge 56 arranged on the upper surface of the mounting seat 55.

[0043] It should be noted that the spindle 22 is rotatably arranged in the inner cavity of the headstock 21, and a CNC slide 41 is arranged on both sides of the spindle 22. The CNC slide 41 is fixedly mounted on the top of the vehicle body 1. The CNC slide 41 is composed of an X-axis moving assembly and a Y-axis moving assembly fixedly mounted on the moving end of the X-axis moving assembly. The X-axis moving assembly and the Y-axis moving assembly are preferably composed of a linear guide, a ball screw, and a servo motor. A servo turret 42 is fixedly connected to the moving end of the Y-axis moving assembly.

[0044] A storage box 51 is located below one end of the spindle 22. A fixed seat 52 is fixedly connected to the inner cavity of the storage box 51. A lifting block 53 is slidably connected to the inner wall of the fixing seat 52. A mounting seat 55 is fixedly connected to the top of the lifting block 53. A wiping sponge 56 is wrapped around and fixed to the upper surface of the mounting seat 55. A first spring 54 is installed between the top of the fixing seat 52 and the bottom of the mounting seat 55.

[0045] When in use, the motor is connected to the main shaft 22 through the transmission belt, and the metal raw material is fixed on the main shaft 22. During the installation of the metal raw material, it is necessary to press the mounting seat 55 downward to retract the lifting block 53 into the fixing seat 52 to prevent the mounting seat 55 from affecting the installation of the metal raw material during the installation process. After the metal raw material is installed, the mounting seat 55 will be pushed upward under the elastic force of the first spring 54, so that the wiping sponge 56 is tightly fitted with the outer wall of the metal raw material. When the metal raw material is processed, the main shaft will drive the metal raw material to rotate at high speed, and the wiping sponge 56 that is tightly fitted with the metal raw material will wipe off the metal chips stuck on the surface of the metal raw material, and the metal chips during the processing will also fall into the storage box 51 for collection.

[0046] In summary, by providing a wiping sponge 56 that can always be in contact with the metal raw material, the metal raw material will continue to rotate during processing, and the wiping sponge 56 will always be in contact with its outer wall, which will wipe off the metal chips stuck on the outer wall while also cleaning the surface of the metal raw material, so that the metal parts after processing do not need to be cleaned again.

[0047] like Figures 1 to 5 As shown, as an optional embodiment: the locking unit 6 includes a pushing component 61 arranged between the fixed seat 52 and the lifting block 53, a sealing component 62 arranged on one side of the pushing component 61, a reset component 63 arranged in the inner cavity of the sealing component 62, and a driving component 64 arranged on one side of the reset component 63.

[0048] It should be noted that the pushing assembly 61 can retract the lifting block 53 in the unprocessed state into the fixed seat 52, the sealing assembly 62 can prevent iron filings from leaking from the connecting part, and the driving assembly 64 is connected to the pushing assembly 61 through the resetting assembly 63.

[0049] Specifically preferably, the pushing assembly 61 includes a triangular groove 611 opened on one side of the lifting block 53, and an inserting block 612 slidably arranged on one side of the fixing seat 52;

[0050] One end of the insert block 612 is slidably connected to the oblique side of the triangular groove 611 .

[0051] It should be noted that a triangular groove 611 is opened on one side of the lifting block 53 , and an insert block 612 is slidably connected in the fixing seat 52 , and one end of the insert block 612 is slidably connected to the triangular hypotenuse of the triangular groove 611 .

[0052] Specifically, preferably, the sealing assembly 62 includes a sealing cylinder 621 provided on the inner wall of the storage box 51, a first piston plate 622 slidably connected to the inner wall of the sealing cylinder 621, and a connecting rod 623 provided on the outer wall of one side of the first piston plate 622;

[0053] One end of the connecting rod 623 is fixedly connected to an outer wall of one side of the insert block 612 .

[0054] It should be noted that the sealing cylinder 621 is fixedly embedded in the inner wall of the storage box 51. The first piston plate 622 is slidably connected to the inner wall of the sealing cylinder 621. One end of the first piston plate 622 is fixedly connected to the connecting rod 623. One end of the connecting rod 623 is fixedly connected to one end of the insert 612.

[0055] Specifically, preferably, the reset assembly 63 includes a fixed plate 631 disposed in the inner cavity of the sealing cylinder 621, a sliding rod 632 slidably disposed on the inner wall of the fixed plate 631, and a second spring 633 disposed between the sliding rod 632 and the first piston plate 622;

[0056] The elastic coefficient of the second spring 633 is greater than the elastic coefficient of the first spring 54 .

[0057] It should be noted that the inner cavity of the sealing cylinder 621 is fixedly connected to a fixed plate 631, and a sliding rod 632 is slidably connected inside the fixed plate 631. One end of the sliding rod 632 is fixedly connected to the first piston plate 622. A second spring 633 is arranged between the fixed plate 631 and the first piston plate 622, and the elastic coefficient of the second spring 633 is greater than that of the first spring 54. Under normal conditions, the second spring 633 will push the insert block 612 to the deepest point, causing the lifting block 53 to retract into the fixed seat 52.

[0058] Specifically, preferably, the driving assembly 64 includes a gearbox 64-1 provided on the inner wall of the head box 21, a connecting box 641 provided between the gearbox 64-1 and the storage box 51, a first bevel gear 642 provided at the output end of the gearbox 64-1, and a rotating shaft 643 rotatably provided on one side of the inner wall of the connecting box 641. The number of the rotating shafts 643 is two groups, one end of one group of rotating shafts 643 is fixedly connected to the second bevel gear 644, and the outer wall of the other group of rotating shafts 643 is fixedly connected to the gear 645. A first rack 646 is provided below the gear 645, and a transmission assembly 647 is provided between the two adjacent rotating shafts 643;

[0059] The first bevel gear 642 and the second bevel gear 644 are meshed with each other, one end of the first rack 646 is fixedly connected to one end of the slide rod 632 , the first rack 646 is slidably connected to the connecting box 641 , and the input end of the gearbox 64 - 1 is connected to the main shaft 22 .

[0060] It should be noted that a gearbox 64-1 is fixedly connected to the inner wall of the headstock 21. The gearbox 64-1 is a common mechanical device in this field. Its main purpose is to reduce the speed of the main shaft 22 and act on the first bevel gear 642. Two sets of rotating shafts 643 are rotatably connected to one side of the inner wall of the connecting box 641. One end of one set of rotating shafts 643 is fixedly connected to the second bevel gear 644, which meshes with the first bevel gear 642. One end of the other set of rotating shafts 643 is fixedly connected to the gear 645. A first rack 646 is slidably connected to the bottom of the connecting box 641, and the first rack 646 meshes with the gear 645. In addition, one end of the first rack 646 is fixedly connected to one end of the slide bar 632.

[0061] Specifically and preferably, the transmission assembly 647 includes a transmission wheel 647 - 1 provided on the outer wall of the rotating shaft 643 , and a belt 647 - 2 sleeved on the outer wall of the transmission wheel 647 - 1 .

[0062] During use, in a normal state / when the spindle 22 is not in operation, the second spring 633 pushes the first piston plate 622 outward. The first piston plate 622 pushes the insert block 612 toward the inside of the fixing seat 52 via the connecting rod 623. One end of the insert block 612 presses the lifting block 53 downward along the inclined surface of the triangular groove 611, thereby driving the mounting seat 55 to move downward, ensuring that in a normal state / when the spindle 22 is not in operation, the mounting seat 55 does not interfere with the mounting area of ​​the spindle 22.

[0063] When the main shaft 22 is started to process the metal raw material, it drives the first bevel gear 642 to rotate through the gearbox 64-1, and drives one of the rotating shafts 643 to rotate through the second bevel gear 644. The rotating shafts 643 rotate together through the transmission assembly 647, thereby driving the gear 645 to rotate. The rotation of the gear 645 drives the first rack 646 to move. When the first rack 646 moves, it drives the slide bar 632 to move, further gradually withdrawing the insert block 612 from the triangular groove 611. The lifting block 53 moves upward due to the gradual withdrawal of the insert block 612. Under the elastic force of the first spring 54, the mounting seat 55 is pushed upward, so that the wiping sponge 56 is tightly fitted with the outer wall of the metal raw material.

[0064] And the gear 645 rotates continuously following the main shaft 22. When the gear 645 rotates to the last tooth of the first rack 646, since the second spring 633 is in a compressed state, the first rack 646 will be subjected to a pulling force, so that the last tooth is always in contact with the teeth of the gear 645. When the main shaft 22 stops rotating, the second spring 633 will quickly reset, causing the mounting seat 55 to retract into the storage box 51.

[0065] like Figures 1 to 7 As an optional embodiment: the cooling unit 7 includes a sealing tube 71 provided at the bottom of the connection box 641, a water inlet pipe 72 provided at the bottom of the sealing tube 71, a water outlet pipe 73 provided on one side of the sealing tube 71, a one-way valve 74 provided in the inner cavities of the water inlet pipe 72 and the water outlet pipe 73, a second piston plate 75 slidably provided in the inner cavity of the sealing tube 71, a third spring 76 provided between the second piston plate 75 and the sealing tube 71, a second rack 77 provided on the upper surface of the second piston plate 75, a half gear 78 provided on the outer wall of the rotating shaft 643, and a drain pipe 79 provided on the inner wall of the mounting base 55;

[0066] The half gear 78 is meshed with the second rack 77 , the drain pipe 79 is connected to the water outlet pipe 73 , and the water inlet pipe 72 is connected to the bottom of the storage box 51 .

[0067] The one-way valve 74 is preferably a rubber one-way valve.

[0068] The drainage pipe 79 includes a connecting pipe 791 disposed in the inner cavity of the mounting seat 55 and a water distribution pipe 792 disposed on the top of the connecting pipe 791 .

[0069] It should be noted that a sealing tube 71 is fixedly connected to the bottom of the connecting box 641, and a water inlet pipe 72 and a water outlet pipe 73 are respectively provided at the bottom and side of the sealing tube 71. Rubber one-way valves are provided in the inner cavities of both, and the water inlet pipe 72 can only enter, and the water outlet pipe 73 can only go out. A second piston plate 75 is slidably connected to the inner wall of the sealing tube 71, and a second rack 77 is fixedly connected to the top of the second piston plate 75. A half gear 78 is fixedly connected to the outer wall of the rotating shaft 643, and the half gear 78 is meshed with the second rack 77. A third spring 76 is also provided between the second piston plate 75 and the sealing tube 71. A connecting tube 791 is fixedly connected to the inner wall of the mounting seat 55, and a water distribution pipe 792 is fixedly connected to the outer wall of the connecting tube 791. The top of the water distribution pipe 792 extends about 2-3 mm from the top of the mounting seat 55. The connecting tube 791 is connected to the water outlet pipe 73, and the water inlet pipe 72 is connected to the bottom of the storage box 51.

[0070] When in use, when the main shaft 22 rotates, the wiping sponge 56 contacts the metal raw material, and coolant or water is injected into the storage box 51. The rotating shaft 643 drives the half gear 78 to rotate, and the half gear 78 lifts the second rack 77, driving the second piston plate 75 to move upward, and the coolant or water is drawn in through the water inlet pipe 72. Then, when the gearless part of the half gear 78 rotates to the second rack 77, under the squeezing action of the third spring 76, the second piston plate 75 is pushed downward, and the water or coolant is discharged from the water outlet pipe 73 to the connecting pipe 791, and then discharged into the wiping sponge 56 from the water outlet pipe 73. Then, the teeth of the half gear 78 lift the second rack 77 again to continuously inject water or coolant into the wiping sponge 56. The wet wiping sponge 56 can cool the metal raw material to prevent the problem of deformation caused by overheating of the processed surface of the metal raw material during processing. At the same time, the contact area between the wet wiping sponge 56 and the metal raw material will become larger, which will further improve the cleaning efficiency.
