Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and in particular relates to a metal cutting tool with a coolant supply. Background Art

[0002] Metal materials will be processed in mechanical processing. At this time, machine tools with corresponding processes will be needed. When the machine tools process metals, they will need to be processed by the required tools. Among them, milling cutters will be used for metal cutting, and milling cutters can cut metal.

[0003] During the installation and use of current metal cutting tools, the cutter head will come into contact with the metal surface, which will generate a large amount of heat. Excessive heat may cause the cutter head to break, so it needs to be cooled. Generally, external cooling is used, which may be inconvenient when used, and the heat dissipation efficiency is low, so it cannot run for a long time.

[0004] After searching, the patent application number "CN202321497715.3" disclosed in "a metal cutting tool with coolant supply" is also an increasingly mature technology. The cooling structure can facilitate the heat dissipation of the cutter head. When the cutter head is in use, a large amount of heat will be generated. At this time, the heat will be transmitted to the inside of the tool body, and the liquid inlet inputs coolant into the inside of the outer rotating ring. The coolant enters the inside of the inner rotating ring from the inside of the outer rotating ring, and then the coolant is transmitted to the inside of the liquid guide cavity through the inner rotating ring. The liquid guide cavity contacts the coolant with the plug block through the liquid guide hole. The plug block can conduct heat to the cutter head, allowing the coolant to absorb heat, and the liquid outlet can discharge The coolant can be discharged and heat can be dissipated through the circulation of the coolant. The inner swivel rotates inside the swivel groove to maintain the position of the outer swivel, which is more convenient to fix the position of the outer swivel and more stable to use. However, although the above patent designs a liquid outlet, the flow process of the coolant will lead to the tool, and then the coolant will be in the liquid guide hole. At the same time, the coolant cannot flow back, resulting in inconvenience for discharge. Subsequently, the coolant is in a closed space for a long time, and it is easily affected by the external temperature and humidity, and then a chemical reaction occurs to cause precipitation. In view of this, we provide a metal cutting tool with a coolant supply to solve the above problems. Utility Model Content

[0023] During specific use, the connecting rod 5 increases the stability between the cooling mechanism 4 and the connecting shaft 3 , while increasing the rigidity of the connecting shaft 3 .

[0024] Preferably, the fixed block 401 , the connecting block 402 and the rotating block 403 are all hollow, and the bottom end of the rotating block 403 is connected to the flow pipe 8 , and a filter is installed inside the flow pipe 8 .

[0025] When in use, the circulation pipe 8 allows the coolant to be conveniently delivered into the interior of the rotating groove 7 , and then enters the through groove 10 along the rotating groove 7 .

[0026] Preferably, a rotation groove 7 is formed on the surface of the connecting shaft 3 , and the rotation block 403 is adapted to be connected with the rotation groove 7 .

[0027] During specific use, the rotating block 403 is conveniently fixed in the rotating groove 7 for rotation, thereby facilitating the coolant to flow into the rotating groove 7 .

[0028] Preferably, the rotating block 403 is rotatably connected to the connecting shaft 3 via the rotating groove 7 .

[0029] During specific use, the rotating block 403 is rotated along the rotating groove 7 on the surface of the connecting shaft 3 to avoid affecting the normal operation of the cutting tool body 1 .

[0030] Preferably, a through groove 10 is provided inside the connecting shaft 3 and at the bottom end of the rotating groove 7 , and the through groove 10 is communicated with the drainage hole 2 .

[0031] When in use, the coolant entering the through groove 10 flows along the channel to the drain hole 2 , so that the coolant contacts the surface of the cutting tool body 1 and takes away the heat generated by the cutting of the cutting tool body 1 .

[0032] Working principle: First, the cutting tool body 1 is fixed on the machine tool spindle through the connecting shaft 3, and the cutting tool body 1 is driven by the rotation of the machine tool spindle to process the workpiece. When the cutting tool body 1 generates heat during operation, the coolant is sent into the interior of the fixed block 401 from the liquid inlet 6, and then the coolant passes through the connecting pipe 9 from the interior of the fixed block 401 into the interior of the connecting block 402, and then enters the interior of the rotating block 403 along the interior of the connecting block 402, and finally, flows out from the flow pipe 8 at the bottom of the rotating block 403 into the rotating groove 7, followed by the coolant flowing into the through groove 10 at the bottom of the rotating groove 7, and then flows along the through groove 10 to the drain hole 2, and then flows along the drain hole 2 to the surface of the cutting tool body 1, and the heat generated by the cutting tool body 1 is taken away during the flow of the coolant.

[0033] It should be noted that the coolant flows from the drain hole 2 to the surface of the cutting tool body 1, thereby facilitating the cooling of the cutting tool body 1, and the coolant will not remain in the through groove 10 and be difficult to flow out. Then, the filter net inside the connecting pipe 9 and the flow pipe 8 is also convenient for filtering the coolant to prevent the precipitate inside the coolant from flowing to the surface of the cutting tool body 1, causing scratches on the workpiece cut by the cutting tool body 1.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
