[0028] See also Figures 1 to 5 The utility model provides a technical solution: a CNC lathe for automatically cleaning waste chips, including a shell 4, the bottom of the shell 4 is fixed to a base 8 by a plurality of legs 1, the legs 1 here may not be installed on the base 8, and may be directly placed on the ground, one end of the interior of the shell 4 is rotatably connected to a rotating shaft 16, one end of the rotating shaft 16 is connected to a second motor 15, the second motor 15 is fixed inside the shell 4, a chuck 3 is installed at the other end of the rotating shaft 16, a CNC turning mechanism is installed at the top of the interior of the shell 4, the CNC turning mechanism is located above the chuck 3, the chuck 3 is one of a three-claw chuck, a four-claw chuck, and a five-claw chuck, when in use, a workpiece is placed on the chuck 3, and the workpiece can be clamped and fixed by the chuck 3.

In actual use, the mounting seat 19 will be limited by the guide rod 34 when moving, so that the mounting seat 19 remains stable.

[0030] like Figure 2 As shown, the bottom of the mounting seat 19 is connected to an L-shaped mounting plate 20, the top of the L-shaped mounting plate 20 is connected to a hydraulic rod 23, a horizontal plate 31 is provided below the L-shaped mounting plate 20, the top of the horizontal plate 31 is fixed to the bottom end of the hydraulic rod 23, and the bottom of the horizontal plate 31 is connected to a tool 25 through a tool holder 24, the tool 25 is located above the chuck 3, and a nozzle 21 is installed on one side of the horizontal plate 31, and the nozzle 21 is connected to the cooling mechanism. The lifting and lowering of the hydraulic rod 23 can drive the tool 25 to move up and down, so that when turning the workpiece, the tool 25 can contact the surface of the workpiece under the action of the hydraulic rod 23 to turn the workpiece.

[0031] It should be noted that at least one limiting rod 22 is vertically mounted on the top of the horizontal plate 31, and the top of the limiting rod 22 slides through the bottom end of the L-shaped mounting plate 20. Under the action of the limiting rod 22, the horizontal plate 31 can be limited, so that the horizontal plate 31 can remain stable when moving, which can prevent the tool 25 from shaking during cutting.

[0032] When turning the tool, the staff can clamp the workpiece through the chuck 3, and then drive the chuck 3 to rotate through the second motor 15, so that the workpiece rotates with the chuck 3, and then adjust the tool 25 to a preset position through the hydraulic rod 23, and then the linear drive module 18 works to drive the tool 25 to move along the preset track. The cutting part of the tool 25 contacts the surface of the workpiece to perform cutting processing on the workpiece.

[0033] like Figure 4 As shown, the interior of the housing 4 is V-shaped and the third guide plate 14 is opened downward. The third guide plate 14 is located below the chuck 3, and both ends of the bottom of the third guide plate 14 are fixed to the inner wall of the housing 4. Figure 4 As shown, the bottom edges of both sides of the third guide plate 14 are provided with discharge ports 26. In this way, during the turning process, the waste chips generated by turning will be discharged from the housing 4 from the discharge ports 26 along the inclined surface of the third guide plate 14.

Since the first guide plate 12 is tilted, this is more conducive to the sliding of the chips.

[0035] like Figure 3As shown, a screw conveying shaft 28 is coaxially arranged inside the screw conveying trough body 6, and the edge of the screw conveying shaft 28 is in clearance with the inner wall of the screw conveying trough body 6. Both ends of the screw conveying shaft 28 are rotatably connected to the end face of the screw conveying trough body 6, and one end of the screw conveying shaft 28 extends to the outside of the screw conveying trough body 6. The end of the screw conveying shaft 28 located outside the screw conveying trough body 6 is connected to a first motor 7, and the first motor 7 is fixed to the end face of the screw conveying trough body 6. In actual use, the debris entering the screw conveying trough body 6 includes coolant and metal debris. Due to the free flow of coolant, when the screw conveying shaft 28 rotates, the waste debris and coolant can be transported separately, that is, the coolant flows down along the screw conveying trough body 6, and the debris is driven by the screw conveying shaft 28 to move upward, so as to achieve solid-liquid separation and facilitate cleaning.

[0036] like Figure 5 As shown, a drain port 17 is provided at one end of the bottom of the spiral conveying trough body 6 near the first motor 7, and a slag discharge port 29 is provided at the other end of the bottom of the spiral conveying trough body 6. The slag discharge port 29 is arranged at the bottom of the top of the spiral conveying trough body 6, and the drain port 17 is arranged at the bottom of the lower end of the spiral conveying trough body 6, so that the coolant falling into the spiral conveying trough body 6 can flow along the spiral conveying trough body 6 to the drain port 17 and be discharged, and the waste chips falling into the spiral conveying trough body 6 will be transported to the slag discharge port 29 under the action of the spiral conveying shaft 28 and discharged, completing the separation of the coolant and the waste chips.

[0037] Specifically, when the utility model is in use, the waste chips generated during the cutting process of the workpiece and the coolant for cooling the workpiece will fall onto the third guide plate 14 under the action of gravity, and the mixed liquid of the coolant and the waste chips will pass through the discharge port 26 along the third guide plate 14 and fall into the first guide plate 12 below, and then the coolant and the waste chips will fall into the spiral conveying trough 6 along the first guide plate 12, and at the same time, the first motor 7 will work, and the first motor 7 will drive the spiral conveying shaft 28 to rotate, transporting the waste chips to the slag discharge port 29 and discharge them along the slag discharge port 29, and the coolant can flow to the discharge port 17 under the action of its own gravity and be discharged from the discharge port 17.

[0038] Further, such as Figure 3As shown, a second guide plate 13 is installed at one end of the top of the first guide plate 12, and the top of the second guide plate 13 is sealed and connected to the bottom of the shell 4. Two strip baffles 27 are symmetrically installed on the top of the first guide plate 12, and the top of the strip baffles 27 is sealed and connected to the bottom of the shell 4, that is, the discharge port 26 is located between the two strip baffles 27, or it can be said that the bottom opening of the shell 4 is located between the strip baffles 27. In actual use, the second guide plate 13 and the two strip baffles 27 can seal the top and two sides of the first guide plate 12 with the bottom of the shell 4, so that the mixture of coolant and waste chips can only flow along the inclined direction of the first guide plate 12, so that the mixture of coolant and waste chips will not be scattered on the ground when flowing out of the shell 4, so as to avoid pollution.

[0039] Further, such as Figure 5 As shown, a filter screen 33 is installed in the drain port 17, and the top of the filter screen 33 is flush with the bottom end of the inner part of the spiral conveying trough body 6. The filter screen 33 can block part of the waste chips that follow the coolant to the drain port 17 to prevent the waste chips from mixing with the coolant, so as not to affect the subsequent circulation of the coolant, and the waste chips filtered by the filter screen 33 will also be transported to the slag discharge port 29 through the spiral conveying shaft 28 for discharge, and the filter screen 33 will not be blocked by the waste chips.

[0040] like Figure 1 and Figure 2 As shown, the cooling mechanism includes a delivery pump 11 fixed on the base 8, the liquid inlet of the delivery pump 11 is connected to the collection barrel 10 through a pipeline, the liquid outlet of the delivery pump 11 is connected to the infusion pipe 5, the other end of the infusion pipe 5 passes through the housing 4 and is connected to the nozzle 21, and the discharge port 17 is connected to the top of the collection barrel 10 through the discharge pipe 9, and the controller is connected to the delivery pump 11 through a wire. The coolant flowing into the spiral delivery trough body 6 can flow freely to the discharge port 17, and be discharged into the collection barrel 10 through the discharge pipe 9 for centralized collection. At the same time, the controller can control the delivery pump 11 to work, and the delivery pump 11 can deliver the coolant collected in the collection barrel 10 to the nozzle 21 through the infusion pipe 5, and spray it onto the surface of the workpiece through the nozzle 21 to circulate and cool the workpiece.

[0041] like Figure 3 As shown, a slag collecting box 30 is provided below the slag discharge port 29. The slag collecting box 30 is placed on the base 8, and the spiral conveying shaft 28 conveys the waste chips to the slag discharge port 29, and the waste chips can fall into the slag collecting box 30 below along the slag discharge port 29 for collection.

[0042] Further, such as Figure 1As shown, a protective door 2 is provided on one side of the housing 4, and both ends of the side of the protective door 2 are slidably connected to the guide rails on the housing 4 through sliders, and the protective door 2 covers the opening of the housing 4. When cutting, the staff can close the protective door 2, so that when a cutting accident occurs, the protective door 2 can protect the staff and prevent the workpiece or the broken knife from falling out of the housing 4 and injuring the staff.

[0043] It should be noted that if Figure 1 As shown, the utility model also includes a control box 35 arranged on the side of the shell (4). The controller in the control box 35 is connected to the first motor 7 and the delivery pump 11 through data lines, and the controller is also connected to the second motor 15, the linear drive module 18, and the hydraulic rod 23 through data lines. The controller is a PLC logic controller. The linear drive module 18 and the hydraulic rod 23 are controlled by the controller to accurately control the tool and increase the turning accuracy. At the same time, during the turning process, the controller will also control the first motor 7 and the delivery pump 11 to discharge the debris generated by turning into the slag collecting box 30. At the same time, the coolant will flow back to the collection barrel 10. The delivery pump 11 then delivers the coolant in the collection barrel 10 to the nozzle 21, and sprays it onto the workpiece surface through the nozzle 21 to circulate and cool the workpiece and the tool 25.
