[0073] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0074] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0075] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0076] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0077] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0078] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0079] like Figure 1 As shown, an embodiment of the present application provides a CNC machine tool, including a machine body 70, an exhaust duct 80 and an oil collection device. The exhaust duct 80 is installed on the machine body 70 to discharge the exhaust gas in the machine body 70, and the oil collection device is arranged below the exhaust duct 80 and opposite to the exhaust duct 80.

[0080] The cutting oil or cutting fluid that acts as a lubricant during the cutting process of the CNC machine tool may adhere to the inner wall of the exhaust pipe 80 during exhaust. Excessive accumulation of oil on the inner wall of the exhaust pipe 80 will drip downwards. The oil collection device is arranged below the exhaust pipe 80 and opposite to the exhaust pipe 80. The oil dripping from the exhaust pipe 80 can fall into the oil collection device, reducing the possibility of oil dripping onto the machine or the staff. The oil dripping into the oil collection device is then discharged through the oil collection device. The staff does not need to frequently clean the oil stuck in the exhaust pipe 80, reducing the maintenance cost of the CNC machine tool.

[0081] like Figure 2As shown, the embodiment of the present application also provides an oil collection device, including a collection tank 10, a rotating assembly 20 and a drain assembly 30. The collection tank 10 is installed on the body 70 and aligned with the exhaust pipe to receive the oil dripping from the exhaust pipe. The rotating assembly 20 is installed in the collection tank 10 to clean the oil in the collection tank 10. The drain assembly 30 is connected to the outflow end 11 of the collection tank 10 to discharge the oil in the collection tank 10. The oil collection device also includes an air intake assembly 40. The air intake assembly 40 is connected to the rotating assembly 20. When the air intake assembly 40 is ventilated, it can drive the rotating assembly 20 to rotate, thereby driving the oil in the collection tank 10 to flow to the outflow end 11, so that the rotating assembly 20 can clean the oil in the collection tank 10. The air intake assembly 40 is also connected to the drain assembly 30. When the air intake assembly 40 is ventilated, the drain assembly 30 can be opened to guide the oil at the outflow end 11 to be discharged.

[0082] The collection tank 10 is used to collect the oil stains dripping from the exhaust pipe, which can reduce the possibility of the oil stains in the exhaust pipe dripping onto the machine platform, thereby improving the cleanliness of the machine platform. The exhaust pipe 80 is located on the side close to the opening of the machine body 70, which can also reduce the possibility of the oil stains dripping onto the operator when the operator replaces the tool head in the CNC machine tool. The rotating assembly 20 and the sewage discharge assembly 30 are both connected to the air intake assembly 40. When the air intake assembly 40 is ventilated, the oil stains in the collection tank 10 can be cleaned, reducing the possibility of the oil stains remaining inside the collection tank 10.

[0083] like Figure 3 , Figure 4 and Figure 5 As shown, in a possible embodiment, the collection tank 10 includes a tank body 12 and a guide portion 13, one end of the guide portion 13 is connected to the tank body 12, and the other end is connected to the outflow end 11. At least two mounting portions 14 are provided on the side of the tank body 12 away from the guide portion 13, and the at least two mounting portions 14 are symmetrically arranged about the center of the tank body 12. The oil collection device also includes a fixing member 60, one end of the fixing member 60 is provided with a connecting portion 61 for connecting to a CNC machine tool equipped with the oil collection device, and the other end is provided with a fixing groove 62, and the side of the mounting portion 14 away from the tank body 12 extends into the fixing groove 62, so that the collection tank 10 is installed in the CNC machine tool.

[0084] The mounting portion 14 is located on the side of the tank body 12 away from the guide portion 13, and extends in a direction away from the tank body 12. The mounting portion 14 is mounted on the body 70 of the numerical control machine tool through the fixing member 60 on the side away from the tank body 12, so that there is a distance between the tank body 12 and the exhaust pipe on the body 70, and the possibility of the tank body 12 affecting the exhaust function of the exhaust pipe can be reduced. A bending portion 141 is provided at one end of the mounting portion 14 away from the tank body 12. The bending portion 141 is bent in a direction close to or away from the central axis of the collection tank 10 along the radial direction of the collection tank 10. The bending portion 141 can extend into the fixing groove 62 of the fixing member 60, so that the collection tank 10 can be detachably mounted on the fixing member 60, which is convenient for the inspection or replacement of the collection tank 10. After the bent portion 141 extends into the fixing groove 62, the bent portion 141 abuts against the side walls of the fixing groove 62 to limit the relative position of the bent portion 141 and the fixing member 60, thereby reducing the possibility of the collection tank 10 falling. The connecting portion 61 in the fixing member 60 can be welded to the machine body 70 or connected by screws to fix the fixing member 60 to the machine body 70. The fixing member 60 can be a Z-shaped structure, and along the height direction Z of the CNC machine tool, the fixing groove 62 is lower than the connecting portion 61, so that there is a gap between the fixing groove 62 and the inner wall of the machine body 70. When the collection tank 10 is installed on the fixing member 60, the bent portion 141 can extend into the fixing groove 62 from the opening at the upper end of the fixing groove 62, thereby facilitating the installation of the collection tank 10.

[0085] like Figure 3 and Figure 6 As shown, in a possible embodiment, the cross-sectional area of ​​the guide portion 13 gradually decreases in the direction close to the outflow end 11, so that the collection tank 10 is funnel-shaped. A guide groove 131 is provided on the inner wall of the guide portion 13, and the guide groove 131 extends from the tank body 12 to the outflow end 11.

[0086] The tank body 12 of the collection tank 10 faces the exhaust pipe and is used to collect the oil and dirt dripping from the exhaust pipe. The cross-sectional area of ​​the tank body 12 is greater than or equal to the cross-sectional area of ​​the exhaust pipe, which is convenient for the collection tank 10 to collect the oil and dirt. The cross-sectional area of ​​the outflow end 11 of the collection tank 10 is small, which is convenient for connection with the sewage discharge assembly 30. The guide part 13 connects the tank body 12 and the outflow end 11, and a guide groove 131 is provided on the inner wall of the guide part 13 to facilitate the oil and dirt to flow to the outflow end 11.

[0087] In a possible embodiment, the inner wall surface of the guide portion 13 can be coated with an anti-stick material, so that the oil stains dripping onto the inner wall of the guide portion 13 can flow along the inner wall of the guide portion 13 to the outflow end 11, thereby facilitating the cleaning of the oil stains in the collection tank 10.

[0088] like Figure 2 and Figure 7As shown, in a possible embodiment, the air intake assembly 40 includes a first air intake pipe 41, and the rotating assembly 20 includes a main body 21. The main body 21 is a hollow structure, and a connection port is provided at the end thereof for connecting with the first air intake pipe 41, so that the first air intake pipe 41 can pass high-pressure gas into the main body 21. A plurality of spray rods 22 are provided along the circumference of the main body 21, and the spray rods 22 protrude from the side wall of the main body 21. The spray rods 22 are also a hollow structure, one end of which is connected to the main body 21, and the other end is inclined toward the direction close to the outflow end 11, and an air outlet 221 is provided at the end thereof, so that the spray rods 22 spray the high-pressure gas onto the inner wall of the guide portion 13.

[0089] The rotating assembly 20 is installed in the collection tank 10, and the spray rod 22 is located in the collection tank 10 at a position corresponding to the guide part 13. The high-pressure gas passed into the main body 21 by the first air inlet pipe 41 can be sprayed to the inner wall of the guide part 13 through the spray rod 22. The spray rod 22 is inclined toward the outflow end 11, so that the high-pressure gas blown out of the spray rod 22 can blow the oil attached to the inner wall of the guide part 13 to the outflow end 11, so as to clean the inner wall of the collection tank 10 and make the oil in the collection tank 10 flow into the sewage discharge assembly 30.

[0090] like Figure 7 and Figure 8 As shown, in a possible embodiment, the air outlet 221 at the end of the spray rod 22 is inclined along the circumference of the rotating assembly 20 , and the air outlet holes 221 on the plurality of spray rods 22 are all inclined along the clockwise or counterclockwise direction of the rotating assembly 20 .

[0091] The main body 21 includes a first section 211 and a second section 212, which are rotatably connected, and both of the first section 211 and the second section 212 are hollow structures, so that high-pressure gas can be transmitted from the first section 211 to the second section 212. The first section 211 is connected to the first air inlet pipe 41, and the injection rod 22 is arranged in the second section 212. The air outlet 221 is inclined in the clockwise or counterclockwise direction of the rotating component 20. When the high-pressure gas in the injection rod 22 is blown out from the air outlet 221, the high-pressure gas will blow to the side wall of the guide groove 131. Under the action of the reaction force, the second section 212 will rotate counterclockwise or clockwise, so that the high-pressure gas ejected from the air outlet 221 can sweep the inner wall of the guide part 13 along the circumferential direction, reducing the possibility of oil residue on the inner wall of the guide part 13.

[0092] like Figure 7 As shown, in a possible embodiment, the rotating assembly 20 also includes a support member 23, which is sleeved on the first section 211 of the main body 21, and the side of the support member 23 away from the main body 21 abuts against the inner wall of the tank body 12 to limit the position of the main body 21 in the collection tank 10.

[0093] The support member 23 includes a mounting portion 14 and a plurality of support rods. The mounting portion 14 is sleeved on the first section 211 of the main body 21. The plurality of support rods are arranged along the circumference of the mounting portion 14, so that the end of the support rod away from the mounting portion 14 abuts against the inner wall of the tank body 12, which can limit the relative position of the main body 21 and the collection tank 10 along the radial direction of the tank body 12, so that the second section 212 of the main body 21 is more stable when rotating, which is conducive to improving the cleaning effect of the guide portion 13 of the collection tank 10. The plurality of support rods can be arranged in a centrally symmetrical manner with respect to the mounting portion 14, so that the support rods are more stable after abutting against the inner wall of the tank body 12, and the stability of the main body 21 can be improved when the second section 212 of the main body 21 rotates.

[0094] like Figure 2 and Fig. 9 As shown, in a possible embodiment, the sewage discharge assembly 30 includes a connecting piece 31, and a first connecting port 311 is provided on one side of the connecting piece 31 along the height direction Z of the oil collection device, and a second connecting port 312 and a third connecting port 313 are provided at both ends of the connecting piece 31 along the width direction X of the oil collection device. The first connecting port 311 is connected to the outflow end 11 of the collection tank 10, and the oil in the collection tank 10 can flow into the connecting piece 31 through the first connecting port 311. The third connecting port 313 is connected to the recovery box, and the oil in the connecting piece 31 can flow into the recovery box through the third connecting port 313. The air intake assembly 40 includes a second air intake pipe 42, and the second air intake pipe 42 is connected to the second connecting port 312.

[0095] The connecting piece 31 is used to discharge the oil in the collection tank 10 into the recovery box. The first connecting port 311 is arranged on one side of the connecting piece 31 along the height direction Z, so that the oil in the collection tank 10 can drip into the connecting piece 31 under the action of gravity. The second connecting port 312 and the third connecting port 313 are arranged on both sides of the connecting piece 31 along the width direction X. When the second air inlet pipe 42 connected to the second connecting port 312 passes high-pressure gas into the connecting piece 31, the flow rate in the connecting piece 31 is increased, and the pressure is made lower than the pressure in the collection tank 10, thereby generating a siphon phenomenon, which can suck the oil in the collection tank 10 into the connecting piece 31, and can blow the oil in the connecting piece 31 to the third connecting port 313, and flow into the recovery box through the third connecting port 313, so as to facilitate the cleaning of the oil in the connecting piece 31.

[0096] like Figure 2 and Fig.10 As shown, in a possible embodiment, the sewage discharge assembly 30 also includes a first oil drain pipe 32 and a second oil drain pipe 34, one end of the first oil drain pipe 32 is connected to the first connecting port 311, and the other end is connected to the outflow end 11 of the collecting tank 10, and one end of the second oil drain pipe 34 is connected to the third connecting port 313, and the other end extends into the recovery box.

[0097] The first oil drain pipe 32 and the second oil drain pipe 34 can connect the collection tank 10 and the recovery box, so that the oil in the collection tank 10 can flow into the recovery box along the first oil drain pipe 32, the connecting piece 31 and the second oil drain pipe 34. A locking piece 33 is provided on the side where the first oil drain pipe 32 is connected to the outflow end 11. The locking piece 33 can be a clamp. The first oil drain pipe 32 is sleeved on the outflow end 11, and the locking piece 33 is sleeved on the outside of the first oil drain pipe 32. Then the clamp is locked to improve the reliability of the connection between the first oil drain pipe 32 and the outflow end 11 and reduce the possibility of the first oil drain pipe 32 falling off.

[0098] like Figure 2 and Fig.11 As shown, in a possible embodiment, a stabilizer 35 is provided at one end of the second oil drain pipe 34 extending into the recovery box, and a plurality of through holes 351 are provided on the side wall of the stabilizer 35, and the oil flowing out of the connecting piece 31 is discharged into the recovery box through the stabilizer 35.

[0099] When the second air inlet pipe 42 blows high-pressure gas into the connecting piece 31, the oil flow rate in the second oil discharge pipe 34 is faster, and the stabilizer 35 can reduce the possibility of splashing when the oil flows into the recovery box, making it convenient to recover the oil in the recovery box. At the same time, it can reduce the possibility of oil splashing and polluting the external environment.

[0100] like Figure 2 and Fig.12 As shown, in a possible embodiment, the oil collection device further includes a control device 50, which may be a solenoid valve for controlling the ventilation of the air intake assembly 40. The control device 50 may be electrically connected to the timing device 90, and the opening and closing of the control device 50 is controlled by the timing device 90, thereby controlling whether the air intake assembly 40 is ventilated. The control device 50 includes an air inlet 51, a first air outlet 52, and a second air outlet 53. The air intake assembly 40 further includes a third air inlet pipe 43, which is connected to the air inlet 51 on the control device 50, the first air inlet pipe 41 is connected to the first air outlet 52, and the second air inlet pipe 42 is connected to the third air outlet. The timing device 90 can control whether the high-pressure gas in the first air inlet pipe 41 is passed into the first air inlet pipe 41 or the second air inlet pipe 42 by controlling the opening and closing of the control device 50, thereby controlling the opening and closing of the rotating assembly 20 and the sewage discharge assembly 30.

[0101] The staff can set the first preset time and the second preset time through the control panel of the timing device 90. When the time reaches the first preset time, the timing device 90 sends a signal one, the control device 50 receives the signal one, and the first air outlet 52 opens, so that the first air inlet pipe 41 in the air inlet assembly 40 can pass high-pressure gas into the rotating assembly 20, so that the rotating assembly 20 rotates, and the high-pressure gas sprayed by the spray rod 22 in the rotating assembly 20 cleans the oil stains on the inner wall of the collection tank 10, so that the oil stains flow from the outflow end 11 to the first oil drain pipe 32, and then the timing device 90 stops sending the signal one, and the first air outlet 52 of the control device 50 is closed.
