[0032] The present invention will be described in further detail below with reference to the accompanying drawings.

[0033] The working principle of this utility model is as follows Figures 1-4 As shown, a central water outlet filter structure for a high-speed CNC drilling and milling machine includes a filter structure body 1. First, a groove 2 is opened in the middle of the front end of the filter structure body 1, and a water inlet hole 3 is opened in the middle of the top wall of the groove 2. At the same time, a water outlet hole 4 is opened in the middle of the bottom wall of the groove 2. It should be noted that the water inlet hole 3 and the water outlet hole 4 are coaxial, and the diameter of the water inlet hole 3 is smaller than the diameter of the water outlet hole 4. Then, a rotating block 17 is provided above the groove 2. Here, the rotating block 17 is rotatably connected to the front end of the filter structure body 1, and then a sealing cover 16 is fixedly connected to the bottom end of the rotating block 17. It should be noted that the rear part of the sealing cover 16 is located in the groove 2. In addition, a sealing ring is fixedly connected to the outer wall of the sealing cover 16 to reduce impurities from entering the groove 2.

[0034] Then, a filter block 5 is provided in the groove 2, and a through hole 9 is provided in the middle of the top of the filter block 5. Here, the diameter of the through hole 9 is larger than the diameter of the water inlet hole 3 and smaller than the diameter of the water outlet hole 4, and the through hole 9 and the water inlet hole 3 are coaxial, so that the liquid coming out of the water inlet hole 3 can flow to the middle of the through hole 9, and the filtered liquid from the through hole 9 can flow to the outside from the water outlet hole 4. Then, a filtering device 11 is provided at the lower part of the outer wall of the through hole 9. The filtering device 11 can filter out solid impurities in the liquid. Then, an inclined ring 10 is fixedly connected to the upper part of the inner wall of the through hole 9. The slope on the inclined ring 10 can make the liquid flow to the center, so that it can be better filtered. In addition, a sealing strip 19 is fixedly connected to the front and rear parts of the top wall of the groove 2 and the front and rear parts of the bottom wall of the groove 2. Here, the sealing strip 19 can not only prevent liquid leakage, but also make the filter block 5 more stable.

[0035] A positioning groove 12 is then opened in the middle of the rear wall of the groove 2, wherein an electric push rod 15 is fixedly connected to the rear wall of the positioning groove 12. At the same time, a connecting block 6 is fixedly connected to the middle of the rear end of the filter block 5, wherein a connecting groove 7 is opened in the middle of the rear end of the connecting block 6. Here, the front end of the output shaft of the electric push rod 15 is inserted into the connecting groove 7, and a quick release device 8 is provided at the top of the connecting block 6 to connect the connecting block 6 and the electric push rod 15 together;

[0036] Finally, in order to reduce the amount of liquid entering the positioning groove 12, a blocking block 13 is fixedly connected to the front end of the inner wall of the positioning groove 12, and a telescopic hole 14 is opened in the middle of the front end of the blocking block 13. Here, the electric push rod 15 is located in the telescopic hole 14, and a sealing ring 18 is fixedly connected to the inner wall of the telescopic hole 14. In this way, the sealing ring 18 is used in conjunction with the electric push rod 15 to reduce liquid leakage.

[0037] The above-mentioned structures together constitute the general appearance structure of the central water outlet filter structure for high-speed CNC drilling and milling machines of the present invention.

[0038] In order to further explain the specific working principle of the central water outlet filter structure for high-speed CNC drilling and milling machines of the present invention, the filtering device 11 includes a threaded groove 1103 opened at the lower part of the inner wall of the through hole 9, and an external threaded ring 1104 is arranged immediately below the inclined ring 10, wherein the threaded portion of the external threaded ring 1104 is threadedly connected to the threaded groove 1103, and then a filter plate 1102 is arranged at the top of the external threaded ring 1104, and a fixing ring 1101 is arranged above the filter plate 1102, where the outer wall of the fixing ring 1101 is fixedly connected to the inner wall of the through hole 9, and the filter plate 1102 can be fixed here by the fixing ring 1101 and the external threaded ring 1104, and then in order to facilitate the user to remove the external threaded ring 1104, the front and rear parts of the inner wall of the external threaded ring 1104 are fixedly connected with receiving blocks 1105.

[0039] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: the user screws the two receiving blocks 1105, and then the receiving blocks 1105 will drive the external threaded ring 1104 to rotate. When the threaded portion on the external threaded ring 1104 is completely moved out of the thread groove 1103, the external threaded ring 1104 will no longer limit the position of the filter plate 1102. At this time, the external threaded ring 1104 is moved out of the through hole 9, and the user can take out the filter plate 1102 and replace it with a new filter plate 1102.

[0040] In order to further explain the specific working principle of the central water outlet filter structure for high-speed CNC drilling and milling machines of the present invention, the quick-release device 8 includes a fixing groove 802 opened on the output rod of the electric push rod 15, wherein the fixing groove 802 on the electric push rod 15 is located in the connecting groove 7 of the connecting block 6, and at the same time, a fixing hole 801 used to cooperate with the fixing groove 802 is opened in the middle of the top of the connecting block 6. It should be noted here that the fixing hole 801 is connected to the connecting groove 7, and then a fixing hole 801 is slidably connected in the fixing hole 801. The fixed shaft 806, wherein the lower part of the fixed shaft 806 is inserted into the fixed groove 802, and then the front and rear parts of the fixed shaft 806 are fixedly connected with the sliding block 804. At the same time, the front and rear parts of the fixed hole 801 are provided with sliding grooves 803 for cooperating with the sliding block 804. Here, the sliding block 804 is slidably connected in the corresponding sliding groove 803. In addition, the top ends of the front and rear sliding blocks 804 are fixedly connected with springs 805, and the top ends of the springs 805 are fixedly connected to the top wall of the sliding groove 803.

[0041] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when it is necessary to remove the connecting block 6 from the electric push rod 15, first pull the fixed shaft 806 upward, and the sliding blocks 804 on the front and rear sides move upward in the corresponding sliding grooves 803. At the same time, the sliding blocks 804 will also compress the spring 805 as they move upward, and the fixed shaft 806 will move upward in the fixing hole 801, and the fixed shaft 806 will also move upward in the fixing groove 802. When the fixed shaft 806 is completely moved out of the fixing groove 802, the fixed shaft 806 will no longer fix the position of the connecting block 6. At this time, the connecting block 6 can be removed together with the filter block 5.
