Description

Technical Field

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

[0002] The long tool bar of the machine tool is used to install the milling cutter head to cut the workpiece. During the cutting process, excessively high temperature will have adverse effects on the processing quality, processing efficiency, tool loss, etc. Excessive cutting temperature will accelerate the thermal softening and thermal fatigue damage of the tool, thereby causing increased tool wear and shortening the tool life. At the same time, it may cause local expansion and shape changes of the workpiece, affecting the dimensional accuracy and shape accuracy of the parts. At present, the long tool bar has a cooling structure, which can cool the milling cutter head by spraying water through a nozzle installed near the cutter head.

[0003] At present, the cooling structure of most long tool rods cannot cover the cooling holes or nozzles after cooling the milling cutter head. Impurities will be generated in the subsequent machine tool processing. Some of the impurities will enter the nozzle and cause blockage during the splashing process, thereby reducing the cooling effect. When the blockage is serious, the cooling structure cannot be used normally, and the staff is required to clean the blockage from time to time, which increases the workload of the staff.

The rotating rod 6 is rotatably connected to the penetration of the hollow plate 4, and the rotating rod 6 is fixedly connected to the penetration of the rotating plate 5. The water-passing box 2, the rotating plate 5, and the rotating rod 6 are used in conjunction with each other. When the water of the water-passing box 2 is sprayed out from the water outlet, the rotating plate 5 is rotated to one side under the action of the water flow. When the rotating plate 5 rotates, the rotating rod 6 can be driven to rotate, thereby removing the blocking of the water outlet of the water-passing box 2 by the rotating plate 5. A waterproof bearing seat 7 is sleeved on one side of the surface of the rotating rod 6. One end of the waterproof bearing seat 7 is fixedly connected to the bottom of the hollow plate 4. The inner ring is fixedly connected to the surface of the rotating rod 6, and the waterproof bearing seat 7 can prevent water from flowing into the gap at the bottom of the inner cavity of the mounting seat 1. A linkage mechanism 8 is arranged at the other end of the rotating rod 6, and the linkage mechanism 8 can be operated when the rotating rod 6 rotates. A water storage tank 9 is connected to one side of the inner cavity of the mounting seat 1, and the water flowing out from the inside of the water box 2 will be stored in the inside of the water storage tank 9. A water pipe 10 is connected to one side of the surface of the water storage tank 9, and the water inside the water storage tank 9 will flow into the inside of the water pipe 10. A nozzle 11 is connected to the other end of the water pipe 10, and the water inside the water pipe 10 will be sprayed out from the water outlet of the nozzle 11. The nozzle 11 is used in conjunction with the cutter head 18, and the nozzle 11 is in an inclined state and the nozzle 11 The water outlet is facing the cutter head 18, and the water sprayed from the nozzle 11 can cool the cutter head 18 to prevent the cutter head 18 from overheating during use, which may cause the cutter head 18 to be quickly damaged. A protective shell 13 is bolted to one side of the surface of the mounting seat 1, and the nozzle 11 and the parts on the inner wall of the linkage mechanism 8 can be protected under the action of the nozzle 11. A fixing rod 12 is rotatably connected to one side of the top of the inner cavity of the protective shell 13, and a baffle 14 is fixedly connected to the surface of the fixing rod 12. One side of the surface of the baffle 14 is slidably connected to the inner wall of the protective shell 13. The protective shell 13 is used in conjunction with the nozzle 11. When the cutter head 18 is not cooled, impurities generated during processing can be prevented from entering the interior of the nozzle 11 under the action of the baffle 14.

[0024] The linkage mechanism 8 includes a first bevel gear 81, one side of the surface of the first bevel gear 81 is fixedly connected to one end of the rotating rod 6, and the first bevel gear 81 can be driven to rotate when the rotating rod 6 rotates; one side of the surface of the first bevel gear 81 is meshedly connected with a second bevel gear 82, and when the first bevel gear 81 rotates, the second bevel gear 82 can be rotated; one side of the surface of the second bevel gear 82 is fixedly connected with a connecting rod 83, and when the second bevel gear 82 rotates, the connecting rod 83 can be rotated; the other end of the connecting rod 83 is fixedly connected with a third bevel gear 84, and when the connecting rod 83 rotates, the third bevel gear 84 can be rotated; one side of the surface of the third bevel gear 84 is meshedly connected with a fourth bevel gear 85, and when the third bevel gear 84 rotates, the fourth bevel gear 85 can be rotated. The four bevel gears 85 rotate, and the meshing direction of the first bevel gear 81 and the second bevel gear 82 is opposite to the meshing direction of the connecting rod 83 and the third bevel gear 84, and the sizes of the first bevel gear 81, the second bevel gear 82, the third bevel gear 84 and the fourth bevel gear 85 are the same. Under the action of the third bevel gear 84, the fourth bevel gear 85 can be rotated in the opposite direction of the first bevel gear 81, and one side of the surface of the fourth bevel gear 85 is fixedly connected to the other end of the fixed rod 12. When the fourth bevel gear 85 rotates, the fixed rod 12 can be rotated. When the fixed rod 12 rotates, the baffle 14 can be driven to rotate, thereby releasing the baffle 14 from blocking the nozzle 11, exposing the nozzle 11 to the outside, and the sprayed water can cool the cutter head 18.

[0025] A torsion spring 15 is fixedly connected to one side of the inner cavity of the mounting base 1, and a retaining ring 16 is fixedly connected to one side of the surface of the rotating rod 6. The torsion spring 15 and the retaining ring 16 are used in conjunction with each other, and one side of the surface of the torsion spring 15 is fixedly connected to the inner wall of the retaining ring 16. The rotating rod 6 is located inside the torsion spring 15. Under the action of the rotating rod 6, the torsion spring 15 can be prevented from having a large degree of displacement. When the rotating rod 6 rotates, the retaining ring 16 can be driven to rotate, and when the retaining ring 16 rotates, the torsion spring 15 can be deflected.

[0026] Working principle: After the nozzle 11 cools the cutter head 18, the water supply to the water box 2 is stopped. Without the impact of the water flow, the clamp ring 16 can drive the rotating rod 6 to rotate under the action of the torsion spring 15. When the rotating rod 6 rotates, the rotating plate 5 can rotate, and the rotating plate 5 rotates toward the direction of the hollow plate 4. When the rotating plate 5 is completely attached to the surface of the hollow plate 4, the rotating plate 5 can continue to block the water outlet of the water box 2. At the same time, when the rotating rod 6 rotates, the first bevel gear 81 can rotate. When the first bevel gear 81 rotates, the rotating plate 5 rotates. When the gear 81 rotates, the second bevel gear 82 can be rotated, when the second bevel gear 82 rotates, the connecting rod 83 can be rotated, when the connecting rod 83 rotates, the third bevel gear 84 can be rotated, when the third bevel gear 84 rotates, the fourth bevel gear 85 can be rotated in the opposite direction, and when the fourth bevel gear 85 rotates, the baffle 14 can be rotated. When the rotating plate 5 blocks the water box 2, the baffle 14 can block the nozzle 11 to prevent impurities from clogging the nozzle 11 when the nozzle 11 is not in use.
