Description

Technical Field

[0001] The utility model relates to the technical field of numerical control drilling machine tools, in particular to a compact small hole electric machining machine tool for numerical control machining. Background Art

[0002] CNC drilling machine tools are digitally controlled hole processing machines mainly used for drilling, and are widely used in industries such as automobiles, locomotives, shipbuilding, aerospace, and engineering machinery.

[0003] After searching, Chinese patent CN216780397U discloses a tight small hole electric machining machine for CNC machining. Although it realizes the functions of preventing the deformation of the workpiece or the connection of the holes processed on the formed workpiece, improving the machining quality and reducing the waste of materials, in the process of tight small hole machining, due to the large number of holes to be drilled on the workpiece, the drill rod will generate more heat during operation. This machine tool lacks the function of cooling the drill rod, which easily causes the drill rod to overheat and produce gaps or fractures, thereby affecting the service life of the drill rod. In addition, when drilling the workpiece, a lot of debris will accumulate around the hole on the workpiece. This machine tool lacks the function of cleaning the debris accumulated around the hole, which leads to the debris blocking the area around the hole, making it inconvenient for people to check the quality of the hole.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 5 In an embodiment of the utility model, a compact small hole electric machining machine tool for numerical control machining comprises a cabinet 1, a drill rod 2 arranged inside the cabinet 1, characterized in that a positioning frame 3 is arranged inside the cabinet 1 near the bottom of the drill rod 2, a water collecting bucket 4 is arranged at the bottom end of the cabinet 1, a water tank 5 is arranged on one side of the cabinet 1, a first pump pipe 6 is connected between the bottom end of the water collecting bucket 4 and the water tank 5, a nozzle 7 is arranged on one side of the drill rod 2, a second pump pipe 8 is connected between the nozzle 7 and the water tank 5, a motor 9 is installed at the top of the water tank 5, a first rotating shaft 10 is connected to the output shaft of the motor 9, the first rotating shaft 10 extends into the interior of the water tank 5 and is connected to a stirring blade 11;

[0023] Wherein, a drying component is provided on one side of the cabinet 1;

[0024] Cooling water is stored inside the water tank 5. The workpiece to be processed is placed on the positioning frame 3. The positioning frame 3 can embed the four corners of the workpiece inside it. When the drill rod 2 moves inside the cabinet 1 and drills the workpiece, the nozzle 7 on one side of the drill rod 2 will move with the drill rod 2. At this time, starting the nozzle 7 can make the cooling water inside the water tank 5 be transported to the nozzle 7 through the second pump pipe 8 and sprayed outward by the nozzle 7. When the cooling water sprayed from the nozzle 7 contacts the drill rod 2, the heat generated on the surface of the drill rod 2 when drilling is performed can be cooled. At the same time, when the cooling water sprayed from the nozzle 7 contacts the workpiece during the drilling process, the debris around the small hole on the workpiece can be washed down, so that the hole formed on the surface of the workpiece is not blocked by the debris, which is convenient for people to check the quality of the hole. The cooling water flowing down from the workpiece will be collected into the first pump pipe 6 through the water collecting bucket 4 at the bottom of the cabinet 1, and will be transported back to the inside of the water tank 5 through the first pump pipe 6, so that the cooling water can be circulated. When the cooling water flows back to the inside of the water tank 5 through the first pump pipe 6, the heat will be brought into the water tank 5. By starting the motor 9, the output shaft of the motor 9 can drive the first rotating shaft 10 to rotate. At this time, the first rotating shaft 10 can drive the stirring blade 11 inside the water tank 5 to rotate. The stirring blade 11 can stir the cooling water inside the water tank 5. Under the stirring action, the heat in the cooling water inside the water tank 5 is dissipated to the external environment faster, thereby ensuring the cooling effect of the cooling water on the drill pipe 2 during the circulation process.

[0025] In one embodiment of the utility model, the air drying assembly includes a pallet 12 connected to one side of the cabinet 1, a second rotating shaft 13 rotatably arranged below the pallet 12, and a fan 14 connected to an end of the second rotating shaft 13 and facing the pallet 12;

[0026] Wherein, a transmission assembly is provided between the first rotating shaft 10 and the second rotating shaft 13;

[0027] While the output shaft of the motor 9 drives the first rotating shaft 10 to rotate, the transmission assembly drives the second rotating shaft 13 to rotate, and the second rotating shaft 13 drives the fan 14 to rotate. At this time, the fan 14 will generate airflow and blow upward to the bottom end of the pallet 12. After the drilling of the workpiece is completed, the workpiece can be taken out of the cabinet 1 and placed on the pallet 12. At this time, the airflow blowing to the bottom end of the pallet 12 can dry the workpiece on the pallet 12 to avoid the residual water stains on the workpiece from affecting the transportation or storage of the workpiece.

[0028] In another embodiment of the utility model, the transmission assembly includes a first gear 15 sleeved on the surface of the first rotating shaft 10, a second gear 16 sleeved on the surface of the second rotating shaft 13, and a belt 17 disposed between the first gear 15 and the second gear 16;

[0029] When the first rotating shaft 10 rotates, the first gear 15 on its surface will be driven to rotate. The first gear 15 drives the second gear 16 to rotate through the transmission effect of the belt 17 , so that the second rotating shaft 13 is driven by the second gear 16 to rotate.

[0030] In another embodiment of the present invention, a cabinet door 18 is installed on the cabinet 1, and a glass observation window 19 is provided on the cabinet door 18 and the side wall of the cabinet 1;

[0031] By opening the cabinet door 18, the workpiece can be placed into the cabinet 1 or taken out from the cabinet 1. When processing the workpiece, closing the cabinet door 18 can prevent cooling water from splashing to the outside of the cabinet 1. At the same time, through the glass observation window 19, people can check the drilling of the workpiece inside the cabinet 1 without opening the cabinet door 18.

[0032] In another embodiment of the present utility model, a filter screen 20 is provided inside the cabinet 1 below the positioning frame 3;

[0033] The debris washed off the workpiece by water will be trapped on the filter screen 20, and the cooling water will flow into the water collecting bucket 4 through the gaps in the filter screen 20, so that the cooling water and the debris falling from the workpiece can be separated, making it convenient for people to centrally process the debris.

[0034] In another embodiment of the present utility model, a lighting lamp 21 is installed on the inner wall of the cabinet 1;

[0035] When drilling a workpiece, the lighting lamp 21 can illuminate the surface of the workpiece. When the surrounding environment is dim, people can also see the hole quality of the workpiece clearly, and it is also convenient to take and place the workpiece in the cabinet 1.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
