Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a lathe tool bar for machine tools. Background Art

[0002] A turning tool is a tool with a cutting part used for turning. The turning tool is one of the most widely used tools in cutting. The working part of the turning tool is the part that produces and processes chips, including the blade, the structure that breaks or rolls up the chips, the space for chip removal or storage, the channel for cutting fluid and other structural elements. When the turning tool head is installed on the turning tool rod for cutting, some chips will be generated, which will affect the cutting efficiency of the turning tool to a certain extent.

[0003] However, when installing the tool head, some existing tool rods can only fix the tool head. When the tool is cutting the pipe, some pipes whose materials are not resistant to high temperatures are prone to local deformation due to the high temperature generated by cutting. In addition, after cutting, the staff needs to manually clean the metal chips inside the pipe, which is very inconvenient. Utility Model Content

[0021] See also Figure 1-4As shown, a tool rod for a machine tool comprises a rod shell 1 and an air inlet port 2 opened at the top of the rod shell 1, a water injection port 3 is also opened at the top of the rod shell 1, a water pipe 4 is welded to the bottom of the water injection port 3, an inner ring 5 is bolted to the outside of the water pipe 4, an outer ring 11 is bolted to the outside of the rod shell 1, a fixing plate 6 is bolted to the bottom of the inner ring 5 and the outer ring 11, the fixed water pipe 4 is used in conjunction with the inner ring 5, the fixing plate 6 and the outer ring 11, the water pipe 4 can be supported by the action of the inner ring 5, and the bottom of the inner ring 5 can be fixed by the fixing plate 6 under the action of the outer ring 11, when the water pipe 4 is injected with water, the weight of the water pipe 4 is prevented from being too heavy, thereby causing the problem of instability inside the tool rod, a rotating blower mechanism 7 is arranged in the middle of the water pipe 4, and the rotating blower mechanism 7 is arranged. The wind mechanism 7 includes a wind wheel 71, which is rotatably connected to the outer side of the water pipe 4. A first bearing 72 is installed in the middle of the wind wheel 71. The inner ring of the first bearing 72 is clamped on the surface of the water pipe 4, and the outer ring of the first bearing 72 is clamped on the inner wall of the wind wheel 71. The first bearing 72 is used in conjunction with the wind wheel 71. Under the action of the first bearing 72, when the wind wheel 71 rotates on the outer side of the water pipe 4, the first bearing 72 can help the wind wheel 71 to rotate on the surface of the first water pipe 4, making the rotation smoother. A plurality of first fan grooves 73 are provided on one side of the wind wheel 71. When wind enters the air inlet 2, wind blows toward the wind wheel 71 from the inside of the rod housing 1. The wind enters through the plurality of first fan grooves 73 of the wind wheel 71, which can drive the wind wheel 71 to rotate. The wind wheel 71 is internally bolted with The connecting rod 74 has a linkage shell 75 bolted to the other side of the connecting rod 74. The connecting rod 74 is used in conjunction with the wind wheel 71 and the linkage shell 75. Under the action of the wind wheel 71, the linkage shell 75 will rotate accordingly. A plurality of second fan grooves 77 are provided inside the linkage shell 75. The second fan grooves 77 facilitate the wind to enter the air inlet 2. When the wind passes through the inside of the rod shell 1 and blows out from the second fan grooves 77, a second bearing 76 is installed in the middle of the linkage shell 75. The outer ring of the second bearing 76 is clamped with the inner wall of the linkage shell 75, and the inner ring of the second bearing 76 is clamped on the surface of the water pipe 4. The second bearing 76 is used in conjunction with the linkage shell 75. Under the action of the second bearing 76, the linkage shell 75 can rotate more smoothly. A sealing ring 10 is installed on one side of the rod shell 1. A flushing mechanism 8 is provided on the outside, and a cutting tool head 9 is threadedly connected to one side of the flushing mechanism 8. The rotating blower mechanism 7 and the flushing mechanism 8 are used in conjunction with each other. The flushing mechanism 8 can flush the cutting tool head 9 and the debris inside the pipe to avoid debris remaining in the pipe after cutting is completed, affecting the cutting effect, and can also cool the inside of the pipe to avoid deformation caused by some pipe materials that are not resistant to high temperatures. The sealing ring 10 can prevent water from splashing into the inside of the rod shell 1 when the flushing mechanism 8 flushes the cutting tool head 9 and the inside of the pipe. The rotating blower mechanism 7 can be set to rotate and blow dry the cutting tool and the inside of the pipe while the flushing mechanism 8 flushes the debris to avoid water remaining in the pipe, so that all positions inside the pipe can be fully blown dry.

[0022] The flushing mechanism 8 includes a water distribution pipe 81, which is connected to the other end of the water pipe 4. Both ends of the water distribution pipe 81 are installed with nozzles 82. The water distribution pipe 81 and the nozzle 82 are used in conjunction with each other. The water distribution pipe 81 can supply water to the nozzle 82. The nozzle 82 can flush the turning head 9 or the debris remaining during cutting inside the pipeline, making the inside of the pipeline cleaner and avoiding debris remaining inside to affect cutting. The inside of the pipeline can also be cooled.

[0023] Working principle: When cutting, first connect the water injection pipe port 3 to the external water pump and hose. Under the action of the water pump, water flows into the two nozzles 82 along the water pipe 4 and the water distribution pipe 81 to flush the cutting head 9 and the debris remaining inside the pipeline, and cool the inside of the pipeline. When using the air inlet pipe port 2 to connect the external fan, under the action of the fan, the wind blows from the inside of the rod shell 1 to the wind wheel 71, and the wind wheel drives the linkage shell 75 to start rotating. The wind passes through the first fan groove 73 and is blown out from the second fan groove 77, and the inside of the pipeline and the cutting head 9 that have just been flushed are dried while rotating to avoid rust inside the pipeline due to unblown areas.
