The tool body is a hollow structure, and a cooling hole is opened through the tool body. The cooling tube and the tool body can be disassembled through the connecting head, making the device easy to carry. At the same time, by providing a control component, when the tool is in use, by pressing the control panel, the movable guide rod moves downward, thereby causing the sealing plate to detach from the water blocking ring, so that the cooling tube remains connected, and water can flow into the tool body through the cooling tube. Then, the high-speed rotating tool throws the water in the tool body out through the cooling hole to achieve cooling treatment, which can effectively avoid affecting the tool service life due to the excessive friction between the tool and the graphite, and also avoid debris splashing everywhere, thereby improving the environmental protection performance of the device.

[0003] However, in the above patent, the tool body is fixed by a threaded connection between the connector and the cooling tube. During the machining process, the cooling tube and the tool body need to be driven to rotate at high speed for drilling, which may cause the tool body and the cooling tube to easily loosen, affecting the stable drilling work.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A drilling tool for a machining center comprises a tool body 1 and a cooling pipe 4 installed at one end of the tool body 1. The tool body 1 is a hollow structure, and a cooling hole 5 is opened through the tool body 1. A drill bit 2 is provided at the end of the tool body 1 away from the cooling pipe 4, and a connector 3 is provided at the end close to the cooling pipe 4. A communicating hole 6 is opened in the middle of the connector 3, and a first stopper 7 is symmetrically installed on the outside, and limiting holes 8 are symmetrically opened on the front and rear walls. A water injection pipe 9 is connected to one side of the cooling pipe 4, and a mounting groove 10 connected to the interior thereof is opened at the bottom. A second stopper 11 is symmetrically installed on the inner wall of the mounting groove 10, and a cavity is symmetrically opened above the second stopper 11. A limiting rod 12 matching the limiting hole 8 is slidably installed inside the cavity, and a spring 13 is installed at one end of the limiting rod 12, and the other end extends through and into the mounting groove 10.

[0020] During installation, align the connector 3 at one end of the tool body 1 with the mounting groove 10 at the bottom of the cooling tube 4, and make the first stop 7 on the outside of the connector 3 and the second stop 11 on the inner wall of the mounting groove 10 in an interlaced position. As the connector 3 is inserted into the mounting groove 10, the first stop 7 will squeeze the limit rod 12 and the spring 13 to retract into the cavity until the first stop 7 is located above the second stop 11. Then, rotate the connector 3 so that the positions of the first stop 7 and the second stop 11 coincide, and adjust the position of the first stop 11 by the second stop 11. Limit, and at the same time, the limit rod 12 restores the elastic force through the spring 13, and will be inserted into the limit hole 8 on the outside of the connecting head 3, respectively, to limit and fix the connecting head 3 again, thereby improving the stability and firmness of the installation, and facilitating installation and disassembly, ensuring the stable progress of the drilling work. When working, water is injected into the cooling pipe 4 through the water injection pipe 9, and the water enters the hollow tool body 1 through the connecting hole 6. When the tool body 1 rotates at high speed for drilling, the water can be thrown out of the tool body 1 through the cooling hole 5 to achieve the purpose of cooling.

[0021] A threaded sealing cover is installed on the outside of the water injection pipe 9 through a threaded connection, which is used to seal the water injection pipe 9 and facilitate disassembly.

[0022] The limiting rod 12 adopts a "T"-shaped structure, and the inner wall of the cavity is symmetrically provided with sliding grooves. Both ends of the limiting rod 12 are respectively slidably connected to the sliding grooves to limit the limiting rod 12 and improve the stability of movement.

[0023] A fixing plate 14 is fixedly installed on the bottom wall of the cavity, and the end of the spring 13 away from the limiting rod 12 is connected to the fixing plate 14. Bar electromagnets with the same magnetic properties are respectively installed inside the fixing plate 14 and one end of the limiting rod 12. A switch button 16 for controlling the power supply of the bar electromagnet is installed on the outside of the cooling tube 4.

[0024] After installation, the bar electromagnet can be energized by pressing the switch button 16. According to the mutual repulsion of like poles, the limit rod 12 can be stably inserted into the limit hole 8, further improving the firmness of the installation. When disassembling, the switch button 16 can be pressed to cut off the power to the bar electromagnet.

[0025] The outer surfaces of the cooling tube 4 and the connector 3 are both provided with diamond-shaped installation marks 15. During installation, the connector 3 can be aligned with the installation marks 15 of the cooling tube 4 first. At this time, the first stop block 7 and the second stop block 11 on the inner wall of the installation groove are just in an interlaced position, which facilitates quick installation.
