[0002] A CNC machine tool is an automated machine tool equipped with a program control system. It can move and process parts according to a pre-programmed program. It integrates mechanical, automation, computer, microelectronics and other technologies to solve the processing problems of complex, precise and small-batch parts. It is a flexible and high-efficiency automated machine tool. CNC machine tools use cutting tools to drill and cut the parts to be processed, thereby performing mechanical processing on them.

By providing the chip removal block, when the tool head is used for internal chip removal, the chips are discharged through the through groove, the chip removal groove and the chip removal port. When the tool head is used for external chip removal, the tool head is directly installed on the tool body through the chuck, and the chips are directly discharged through the outside of the tool head.
[0004] However, in actual use of the existing tools, due to the internal chip removal in the above application documents, the chips generated by processing will continue to move and squeeze out inside the tool body, but the amount of chips will gradually increase during continuous processing. Since the channel structure inside the tool body has corners, the chips are prone to congestion and accumulation when moving inside the tool body, resulting in poor chip removal effect, thereby affecting processing.

The utility model enables the elastic member and the pusher to move together with the tool body, so that the tool body can drive the pusher to rotate together when the tool body rotates, and the pusher can generate an outward centrifugal force to push the debris in the chip removal port to move, so as to push out the internal debris and improve the chip removal effect.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A deep hole drilling tool structure, comprising:
[0008] A tool body connected to the driving mechanism;

[0017] The utility model is further configured that a sealing member is arranged on the inner side of the opening or is connected with a cooling system.
[0018] The utility model is further arranged that the chip removal opening is arranged perpendicularly to the channel formed by the first chuck.
[0019] The beneficial effect of the utility model is that the utility model can move together with the tool body through the elastic part and the pushing part, so that the tool body can drive the pushing part to rotate together when they rotate, and the pushing part can generate an outward centrifugal force to push the debris in the chip removal port to move, so as to push out the internal debris and improve the chip removal effect.

[0021] 2. The deep hole drilling tool structure is provided with a cooling chamber, a seal, a wear-resistant layer and a heat-conducting layer. When the driving mechanism drives the tool to work, the tool is very likely to generate a continuous high temperature environment.

[0031] Reference Figure 1-4 A deep hole drilling tool structure comprises: a tool body 1, which is connected to a driving mechanism; a first chuck 3, which is mounted at one end of the tool body 1; a second chuck 4, which is mounted at the other end of the tool body 1 opposite to the first chuck 3, so that different tool heads can be respectively mounted at the positions of the first chuck 3 or the second chuck 4; a chip removal port 9, which is constructed on the inner side of the tool body 1 and is connected to the first chuck 3, so that when the tool head is installed with the first chuck 3, the chips generated by the tool head can be discharged through the channel of the first chuck 3 and the chip removal port 9; an elastic member 7, which is mounted on the inner side of the chip removal port 9, and a pusher portion 8 is mounted on the movable end of the elastic member 7, and the pusher portion 8 can be connected to the tool through the elastic member 7, so that the pusher portion 8 can move under the elastic action of the elastic member 7.
[0032] Specifically, refer to Figure 1-3 The tool body 1 has an internal structure with a cooling chamber 6 for storing coolant. The surface of the tool body 1 is provided with an opening 2 connected to the cooling chamber 6. Through this implementation, coolant is injected into the cooling chamber 6 through the opening 2 on the surface of the tool, so that a certain amount of coolant can be stored in the cooling chamber 6. The coolant can be cooling oil or water, etc., so that the coolant can effectively reduce the high temperature environment generated when the tool is working during the flow process.
[0033] Furthermore, the interior of the tool body 1 is configured with a channel connecting the cooling chamber 6 and the first chuck 3 and the second chuck 4. Through this design, the coolant can flow from the cooling chamber 6 to the positions of the first chuck 3 and the second chuck 4 through the channel, so that the coolant can be closer to the tool head and perform precise cooling treatment on the tool head, thereby improving the cooling effect.
[0034] Furthermore, the pusher portion 8 is arranged outwardly along the circumferential direction of the axis of the tool body 1. Through this design, the tool body 1 can also drive the pusher portion 8 to rotate together during the mutual rotation process, and the pusher portion 8 is arranged outwardly along the axis, so that the pusher portion 8 can generate a certain centrifugal force during the rotation process, so that the pusher portion 8 can push the debris in the chip removal port 9 to move, and push the internal debris out, thereby improving the chip removal effect. Furthermore, the chip removal port 9 is arranged perpendicular to the channel formed by the first chuck 3 to guide the debris generated during processing at the position of the first chuck 3, so that the debris will be discharged from the tool, corresponding to the installed tool head.
[0035] Specifically, refer to Figure 4 The tool body 1 is respectively constructed with a wear-resistant layer 10, a corrosion-resistant layer 11 and a heat-conducting layer 12. The heat-conducting layer 12 is located on the inner side of the tool body 1, and the wear-resistant layer 10 is located on the outside of the tool body 1. Through this embodiment, the wear-resistant layer 10 can be a cemented carbide or a coating material, etc. The wear-resistant layer 10 is located on the outside of the tool body 1 to increase the surface hardness and wear resistance of the tool, thereby extending the service life of the tool and reducing wear during cutting. The corrosion-resistant layer 11 can be made of a nickel-based alloy or other materials. The corrosion-resistant layer 11 can provide the tool with better corrosion resistance, protect the tool from corrosion, and extend the service life of the tool. The heat-conducting layer 12 can be a thermally conductive coating, a composite material or related metal materials. The heat-conducting layer 12 is located on the inner side of the tool body 1, which can improve the thermal conductivity of the tool, effectively and quickly conduct and dissipate the heat generated during the cutting process, prevent the tool temperature from being too high, and maintain stability and precision during the cutting process.
[0036] Furthermore, a seal 5 is provided on the inner side of the opening 2 or connected to a cooling system. Through this design, the seal 5 can effectively prevent the coolant from leaking out of the opening 2, maintain the circulation and utilization of the coolant inside the tool body, ensure the normal operation of the cooling system, and also connect the tool with an external cooling system to realize the circulation supply and recycling of the coolant, improve the cooling effect and save the use of the coolant.
[0037] Working principle: When using the utility model, the tool is first connected to the driving mechanism, and the tool is driven to rotate by the driving mechanism. After the tool rotates, it will also drive the elastic member 7 and the pusher 8 in the chip discharge port 9 to move, so that the elastic member 7 and the pusher 8 can generate an outward centrifugal force, so that the pusher 8 can push the debris in the chip discharge port 9 to move, so as to eject the internal debris, and the pusher 8 can produce a reciprocating effect under the traction of the elastic member 7, so that the pusher 8 can continuously push the debris to avoid accumulation in the tool and difficulty in discharge or slow discharge, thereby improving the chip removal effect, and under the action of the coolant in the cooling chamber 6, the tool surrounding can be cooled and cooled. The coolant can be supplied through the cooling system and can also flow to the chuck position through the channel inside the tool, thereby improving the cooling effect on the tool. At the same time, under the action of the wear-resistant layer 10 and the heat-conducting layer 12, the wear resistance is improved and the heat is guided to avoid excessive temperature affecting the service life of the tool.
[0038] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
