[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-8 As shown, a deep hole drilling CNC lathe comprises:

[0031] The guide shell 1 is arranged in a vortex shape, and a rotating disk 31 is arranged therein for rotation, and centrifugal blades 311 are arranged on the rotating disk 31 in a circumferential array;

[0032] The rod sleeve 2 is provided with a rubber guide ring 21, and the rubber guide ring 21 is provided with a first rubber ring 211 and a second rubber ring 212;

[0033] The rod sleeve 2 is fixed to the central axis of the guide housing 1 , and the first rubber ring 211 and the second rubber ring 212 are both arranged in a barb shape and are arranged at an acute angle.

[0034] Specifically, when the deep hole drilling CNC lathe is drilling, the coolant is pressurized and discharged through the through hole provided on the drilling cutter head to cool the cutter head, and the coolant and debris are discharged through the drilling hole.

[0035] Furthermore, as the drilling head penetrates deeper, the rubber guide ring 21 on the rod sleeve 2 also enters the drilled hole. The diameters of the barbed tips of the first rubber ring 211 and the second rubber ring 212 are the same as the diameter of the drilling head. When the rubber guide ring 21 enters the drilled hole, a closed space is formed. During drilling, the coolant and debris enter the rod sleeve 2 through the drilled hole and the rubber guide ring 21, and enter the guide shell 1 through the rod sleeve 2, driving the turntable 31 to rotate. The rotation of the turntable 31 drives the centrifugal blades 311 to rotate. The centrifugal blades 311 rotate, providing kinetic energy to the coolant entering the guide shell 1, so that the coolant flows along the centrifugal blades 311, and generates centrifugal force under the push of the centrifugal blades 311 and flows along the inner wall of the guide shell 1 arranged in a vortex shape, as shown in FIG. Figure 6 As shown, the coolant is finally discharged through the water outlet 11 on the guide shell 1. A pipe can be connected to the water outlet 11 to allow the coolant and debris to flow into a designated position for collection. Real-time drainage can be achieved, and drilling and drainage can be carried out simultaneously. There is no need for staff to observe in real time and actively drain, and the degree of automation is high.

[0036] like Figure 3 As shown, since the volume of the enclosed space formed after the rubber guide ring 21 enters the drill hole is small, the coolant quickly gathers after entering the enclosed space, thereby pressurizing the coolant. Since the first rubber ring 211 at the water inlet of the rubber guide ring 21 is arranged in a barb shape, as shown in FIG. Figure 4 As shown, the water inlet of the rubber guide ring 21 is in a micro-trumpet shape. When the coolant enters the rod sleeve 2 along the first rubber ring 211, an extrusion force is applied to the first rubber ring 211, so that the first rubber ring 211 and the second rubber ring 212 are extruded and deformed, so that the angle between the first rubber ring 211 and the second rubber ring 212 changes from an acute angle to an obtuse angle, as shown in FIG. Figure 5 As described above, the first rubber ring 211 and the second rubber ring 212 are closely attached to the inner wall of the rod sleeve 2, thereby improving the sealing of the enclosed space, allowing the rod sleeve 2 to better collect and guide the coolant, and the structure is simple and easy to manufacture.

[0037] In the above technology, a closed space is formed after entering the drill hole through the rubber guide ring 21 on the rod sleeve 2. When drilling, the coolant and debris enter the rod sleeve 2 through the drill hole and the rubber guide ring 21, and enter the guide shell 1 through the rod sleeve 2, driving the turntable 31 to rotate. The rotation of the turntable 31 drives the centrifugal blades 311 to rotate. The centrifugal blades 311 rotate to provide kinetic energy to the coolant entering the guide shell 1, so that the coolant flows along the centrifugal blades 311, and generates centrifugal force under the push of the centrifugal blades 311 and flows along the inner wall of the guide shell 1 arranged in a vortex shape, and finally is discharged through the water outlet 11 on the guide shell 1. A pipe can be connected to the water outlet 11 to allow the coolant and debris to flow into a designated position for collection. Compared with the prior art, real-time drainage can be achieved, drilling and drainage are carried out simultaneously, and there is no need for staff to observe in real time and actively drain. The degree of automation is high, the volume is small, and the normal operation of the machine tool will not be hindered. The structure is simple and easy to manufacture.

[0038] As a further embodiment of the present invention, the present invention further comprises a drill rod 3 disposed at the center axis of the rod sleeve 2 , and a turntable 31 is fixedly disposed on the drill rod 3 .

[0039] Specifically, since the turntable 31 is fixedly arranged on the drill rod 3, when drilling, the drill rod 3 is driven to rotate, thereby driving the turntable 31 to rotate through the drill rod 3, thereby further driving the centrifugal blades 311 to rotate, providing kinetic energy for the coolant entering the guide shell 1 to discharge the coolant, and no additional driving source is required to drive the turntable 31 to rotate, thereby further simplifying the structure and saving manufacturing costs.

[0040] As a further embodiment of the present invention, the present invention further comprises a drill bit 4 fixedly disposed on the drill rod 3, on which coolant ports 41 are arranged in a circumferential array.

[0041] Specifically, the pressurized coolant is sprayed out through the coolant ports 41 arranged in a circumferential array on the drill bit 4. Figure 1 As shown, the drill bit 4 can be quickly cooled, and the debris can be flushed away as the drill bit 4 rotates. Since the coolant ports 41 are arranged in a circular array, the drill bit 4 is not easily eccentric when the coolant is sprayed, thereby improving the machining accuracy of the drill bit 4.

[0042] As a further embodiment provided by the present invention, it also includes spiral guide grooves 42 arranged in a circumferential array on the drill bit 4 .

[0043] Specifically, after the pressurized coolant is sprayed out through the coolant ports 41 arranged in a circular array on the drill bit 4, it flows into the rod sleeve 2 along the spiral guide grooves 42 opened in a circular array on the drill bit 4, thereby providing a flow space for the coolant, thereby preventing the coolant from flowing out from between the drill bit 4 and the borehole wall, causing the drill bit 4 to be eccentric due to the squeezing of the coolant, and at the same time, preventing the drill bit 4 from causing the actual hole diameter to be larger than the preset hole diameter due to the action of the coolant, thereby further improving the processing accuracy.

[0044] Since the spiral guide groove 42 is arranged in a spiral shape, the coolant forms a vortex under the action of the groove wall of the rotating spiral guide groove 42 and enters the rod sleeve 2. When the vortex passes through the rubber guide ring 21, the first rubber ring 211 at the water inlet of the rubber guide ring 21 is arranged in a barb shape. Figure 4 As shown, the water inlet of the rubber guide ring 21 is in a micro-trumpet shape, so that the coolant forming the vortex can enter the rod sleeve 2 more easily. The groove wall of the spiral guide groove 42 realizes a pressurization process for the coolant, thereby increasing the extrusion force applied by the coolant to the first rubber ring 211, so that the first rubber ring 211 and the second rubber ring 212 are more closely attached to the inner wall of the rod sleeve 2, thereby further improving the sealing effect.

[0045] As a further embodiment of the present invention, it also includes an annular group composed of the first stator blades 22 and the second stator blades 23 arranged in an interval circular array, and the annular group is arranged on the inner wall of the rod sleeve 2 in a linear array.

[0046] Specifically, the first stator blades 22 and the second stator blades 23 on the plurality of annular groups arranged in a linear array correspond to each other. After entering the rod sleeve 2, the coolant passes through the annular groups arranged in a linear array on the inner wall of the rod sleeve 2 in sequence, thereby decelerating the coolant entering the rod sleeve 2, thereby preventing the coolant from flowing too fast and affecting the drill rod 3, causing polarization and affecting the processing accuracy.

[0047] Since the annular group is composed of the first stator blades 22 and the second stator blades 23 arranged in an interval circumferential array, and the first stator blades 22 and the second stator blades 23 correspond to each other, the coolant forming the vortex first flows through the guide of the first stator blade 22 to the corresponding second stator blade 23, and then flows through the guide of the second stator blade 23 to the first stator blade 22 of the next annular group, such as Figure 2 As shown, the flow direction of the coolant is changed, thereby preventing the coolant from rotating to form a vortex and forming a stable flow direction, thereby making the cooling flow more stable, and further preventing the coolant from rotating to form a vortex to affect the drill rod 3, thereby improving the stability of the coolant during discharge, thereby improving the stability of the processing, thereby ensuring that the coolant is discharged in real time without affecting the processing accuracy.

[0048] As a further embodiment of the present invention, the first stator blade 22 and the second stator blade 23 are arranged in an arc shape and tilted, and the bending directions are opposite.

[0049] Specifically, when the coolant that forms a vortex flows toward the first stator blade 22, since the first stator blade 22 is arranged in an arc shape and tilted, the coolant flows along the inner arc surface of the first stator blade 22, and flows along the inner arc surface of the first stator blade 22 to the inner arc surface of the second stator blade 23, and collides with the inner arc surface of the second stator blade 23 to decelerate, and then flows along the inner arc surface of the second stator blade 23 to the inner arc surface of the first stator blade 22 to collide and decelerate, and undergoes multiple collisions, decelerations and diversions in sequence, thereby preventing the rotation of the coolant and improving the stability of the coolant flow.

[0050] As a further embodiment provided by the present invention, it also includes guide plates 24 arranged on the inner wall of the rod sleeve 2 in a circumferential array.

[0051] Specifically, as the turntable 31 rotates, the turntable 31 rotates, thereby driving the centrifugal blades 311 to rotate. The centrifugal blades 311 rotate, providing kinetic energy to the coolant entering the guide shell 1, thereby forming a vortex at the liquid inlet of the guide shell 1. The decelerated coolant flows into the space separated by the guide plate 24 and enters the guide shell 1 along the guide plate 24, thereby improving the stability of the coolant when entering the guide shell 1, and further preventing the vortex from affecting the drill pipe 3.

[0052] Working principle: When the deep hole drilling CNC lathe is drilling, the coolant is pressurized and sprayed out through the coolant ports 41 arranged in a circular array on the drill bit 4, and the coolant and debris are discharged through the drill hole. As the drill bit 4 goes deeper, the rubber guide ring 21 on the rod sleeve 2 also enters the drill hole. The diameter of the barbed tip of the first rubber ring 211 and the second rubber ring 212 is the same as the diameter of the drilling bit. When the rubber guide ring 21 enters the drill hole, a closed space is formed. When drilling, the coolant and debris enter the rod sleeve 2 through the drill hole and the rubber guide ring 21. After entering the rod sleeve 2, the coolant passes through the annular group arranged in a linear array on the inner wall of the rod sleeve 2 in turn, thereby slowing down the coolant entering the rod sleeve 2. When the coolant forming a vortex flows toward the first stator blade 22, since the first stator blade 22 is arranged in an arc shape, the coolant flows along the inner wall of the first stator blade 22. The coolant flows along the inner arc surface of the first stator blade 22 to the inner arc surface of the second stator blade 23, collides with the inner arc surface of the second stator blade 23 to decelerate, and then flows along the inner arc surface of the second stator blade 23 to the inner arc surface of the first stator blade 22 to collide with and decelerate. After multiple collisions, decelerations and diversions, the rotation of the coolant is prevented, and the stability of the coolant flow is improved. The coolant after deceleration flows into the space separated by the guide plate 24, and enters the guide shell 1 along the guide plate 24. The drill rod 3 drives the turntable 31 to rotate, and the rotation of the turntable 31 drives the centrifugal blades 311 to rotate. The centrifugal blades 311 rotate to provide kinetic energy to the coolant entering the guide shell 1, so that the coolant flows along the centrifugal blades 311, and generates centrifugal force under the push of the centrifugal blades 311 and flows along the inner wall of the guide shell 1 arranged in a vortex shape, such as Figure 6 As shown, the coolant and the debris are finally discharged through the water outlet 11 on the guide shell 1. A pipe can be connected to the water outlet 11 to allow the coolant and the debris to flow into a designated location for collection.

[0053] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
