Description

Technical Field

[0001] The invention relates to the technical field of milling cutter processing, and in particular to a milling cutter processing device and a use method thereof. Background Art

[0002] A rotary file cutter is a rotary cutting tool used for processing materials such as metal, wood and plastic. Its design features a cutter head with multiple cutting teeth, which can efficiently perform operations such as grinding, trimming, deburring and grooving.

[0003] After long-term use, the teeth on the surface of the rotary file milling cutter will become blunt, and the teeth need to be finely polished using grinding tools such as diamond grinding wheels to make the teeth sharp again. However, long-term use will also cause the surface of the rotary file milling cutter to rust. As for the rust in the gaps formed between the teeth, the diamond grinding wheel is too large to contact the rust, so the grinder can only use sandpaper to grind the rust in the gaps one by one. However, the rotary file milling cutter has a large number of teeth, so more gaps are formed, which significantly increases the difficulty of grinding and reduces the maintenance efficiency of the rotary file milling cutter.

[0004] In addition, during the grinding process, the debris generated is easy to splash and difficult to clean and recycle, and the grinding will generate high temperature. In the existing grinding process, the grinding area is usually cooled by spraying water.

[0034] The lower seat 2 is located at the lower end of the upper seat 1 and is detachably connected thereto, wherein the lower seat 2 and the upper seat 1 are connected by snap-fitting, but not limited to, a grinding groove a101 is provided on the upper end face of the upper seat 1, and an inner wall of the grinding groove a101 is connected to an isolation block 14, a discharge pipe is provided on the isolation block 14, and a valve b15 is provided on the discharge pipe, and the upper end face of the isolation block 14 is tilted downward toward the feed end of the discharge pipe, and diamond grains are stored in the grinding groove a101, and the inner diameter of the grinding groove a101 gradually decreases along the central axis, so that the diamond grains in the grinding groove a101 can smoothly pass through the discharge pipe into the space below the isolation block 14 for temporary storage; a groove a is provided on the lower end face of the upper seat 1, and a groove b201 for placing a milling cutter is provided on the end face of the lower seat 2 facing the upper seat 1, and the groove a is close to the grinding groove a101. The inner wall of the groove a101 is provided with a grinding groove b24, and the grinding groove b24 and the grinding groove a101 are connected through a reflux pipe 11, and the grinding groove b24 and the grinding groove a101 are connected through a feed pipe, and a valve a13 is provided on the feed pipe. The interior of the upper seat 1 is located around the groove a and is provided with an air cavity 16 connected with the groove a, and an elastic membrane 19 is arranged at the connection between the air cavity 16 and the groove a; the air cavity 16 is connected to a micro air pump 17 through a multi-way tube 18, and the micro air pump 17 pumps air into the air cavity 16 through the multi-way tube 18, so that the elastic membrane 19 expands, and the expanded elastic membrane 19 will fill the gap between the teeth, thereby realizing the sealing function of the milling cutter area to be ground, avoiding the leakage of diamond grains, and at the same time ensuring that the high-pressure gas can only flow back to the grinding groove a101 through the reflux pipe 11.

[0035] A plurality of air inlet pipes 23 are provided and connected to the upper seat 1. The plurality of air inlet pipes 23 are all connected to the grinding groove a101 and the feed pipe. The end of the air inlet pipe 23 is connected to the grinding groove a101 through pipe a, and pipe a is U-shaped. The end of pipe a is close to the isolation block 14. The end of the air inlet pipe 23 is connected to the feed pipe through pipe b, and pipe b is L-shaped.

[0036] One end of the air inlet pipe 23 is connected to a high-pressure air pump 6, and an air outlet end of the high-pressure air pump 6 is connected to an air inlet end of a plurality of air inlet pipes 23;

[0037] The multiple cooling ends of the cooling mechanism are respectively connected to multiple air inlet pipes 23;

[0038] The vibration mechanism is connected to the upper seat 1 and is used for supporting and vibrating the upper seat 1 .

[0039] In this embodiment, the milling cutter that needs to be fully polished is placed in the polishing groove a101 through the clamping assembly, and the milling cutter that needs to be partially polished is placed in the groove b201, and the surface to be polished faces the polishing groove b24, and the lower seat 2 is connected to the upper seat 1, and the high-pressure air pump 6 is turned on to pump high-pressure gas into the polishing groove a101 and the polishing groove b24. The high-pressure gas will cause the diamond grains in the polishing groove a101 to roll rapidly, and the rolling diamond grains will quickly rub the rust on the surface of the milling cutter, which can automatically realize the comprehensive polishing of the rust in the gap between the teeth. The debris generated by the grinding rolls upward with the diamond grains. When the debris rolls to the top, it is magnetically attracted to the surface of the end cover 3 under the action of the magnetic member 8 and is automatically recovered;

[0040] The high-pressure gas enters the inner side of the grinding groove b24 and opens the valve a13 at the same time. The high-pressure gas will cause the corundum grains falling into the grinding groove b24 to flow at high speed. The high-speed flowing corundum grains will quickly rub the rust on the surface to be ground of the milling cutter, thereby realizing the local grinding function of the milling cutter. The debris generated by grinding will flow back to the grinding groove a101 through the reflux pipe 11 along with the corundum grains under the blowing action of the high-pressure gas. The debris entering the grinding groove a101 will be magnetically attracted to the surface of the end cover 3 for recovery. There is no need for the grinder to manually take sandpaper for grinding, which reduces the difficulty of grinding the rust in the gap and the workload of the grinder.

[0047] It should be noted that one end of the milling cutter that needs to be polished as a whole is inserted into the groove d901 at the bottom end of the porous plate 9, and then the telescopic device 20 is opened to drive the extrusion component 10 to move downward, and the arc surface of the top of the clamping block 21 is squeezed by the inner wall of the circular opening on the extrusion component 10, so that the clamping blocks 21 around it move toward the center of the groove d901, thereby realizing the clamping and fixing function at one end of the milling cutter.

[0048] Example 5, please refer to Figure 1-8 The present invention provides a method for using a milling cutter processing device, using any of the milling cutter processing devices in the above-mentioned embodiments 1 to 4, and specifically comprising the following steps:

[0049] S1. Preparation: Fix the milling cutter that needs to be fully polished on the clamping assembly, install the end cover on the upper seat, place the milling cutter that needs to be partially polished inside the groove b201, connect the lower seat 2 with the upper seat 1, start the micro air pump 17 to pump air into the air cavity 16, so that the elastic membrane 19 expands and fits on the side wall of the milling cutter, ensuring that the polishing groove b24 forms a closed chamber;

[0050] S2, grinding operation: turn on the cooling mechanism, magnetic member 8, vibration mechanism and high-pressure air pump 6, open valve a13, so that the diamond grains gradually fall into the grinding groove b24, the high-pressure air pump 6 generates high-pressure gas to enter the air inlet pipe 23, and the high-pressure gas enters the grinding groove a101 and the grinding groove b24 after being cooled by the cooling mechanism, so that the diamond grains in the grinding groove a101 roll quickly to grind the milling cutter fixed on the clamping assembly, and the diamond grains and debris in the grinding groove b24 flow into the grinding groove a101 with the high-pressure gas, and the debris gathers on the inner side of the end cover 3 under the magnetic attraction of the magnetic member 8;

[0051] S3. After grinding is completed: when all the diamond sand and debris in the grinding groove b24 enter the grinding groove a101, turn off the high-pressure air pump 6, the cooling mechanism and the vibration mechanism, relieve the pressure on the grinding groove a101 through the pressure relief valve 12, remove the end cover 3 and take out the milling cutter on the clamping assembly, then remove the lower seat 2 from under the upper seat 1, and take out the milling cutter in the groove b201.

[0052] It should be noted that the material used in the rotary file milling cutter targeted in this patent application can be magnetically attracted.

[0053] In summary, when the present invention is used, one end of the milling cutter that needs to be fully polished is inserted into the groove d901 on the porous plate 9, and then the telescopic device 20 is opened to drive the extrusion component 10 to move downward, and the inner wall of the circular opening on the extrusion component 10 is used to squeeze the arc surface of the top of the clamping block 21, so that the clamping blocks 21 around move toward the center of the groove d901, so as to realize the clamping and fixing function at one end of the milling cutter, and then the end cover 3 is detachably installed at the top of the upper seat 1, and at the same time, the milling cutter enters the polishing groove a101 and is immersed in the diamond grains;

[0054] Then, the milling cutter that needs to be partially polished is placed horizontally in the groove d901 on the lower seat 2, and the surface to be polished of the milling cutter is arranged to face the polishing groove b24. Then, the lower seat 2 is detachably mounted at the bottom end of the upper seat 1, and then the micro air pump 17 is used to pump air into the air cavity 16 to expand the elastic membrane 19. The expanded elastic membrane 19 will fill the gaps between the teeth to achieve the sealing function of the area to be polished of the milling cutter, avoid the leakage of diamond grains, and ensure that the high-pressure gas can only flow back to the polishing groove a101 through the reflux pipe 11;

[0055] Before the grinding operation is performed, the vibration motor 7 and the valve b15 are turned on first, so that part of the diamond grains in the grinding groove a101 can fall into and fill the area below the isolation block 14, and then the valve b15 is closed;

[0056] When performing the grinding operation, the magnetic part 8, the high-pressure air pump 6, the valve a13 and the pump body are turned on. The high-pressure air pump 6 fills the air inlet pipe 23 with high-pressure gas. At the same time, the pump body injects the cold water in the water tank 5 into the spiral cooling pipe 22 through the connecting pipe. When the cold water flows in the spiral cooling pipe 22, it will take away part of the heat of the high-pressure gas in the air inlet pipe 23, thereby cooling the high-pressure gas. When the cold water flows to the end of the spiral cooling pipe 22, it flows back to the water tank 5 through the built-in pipe to complete the circulation, thereby realizing the function of circulating cooling.

[0057] When the cooled high-pressure gas flows to the end of the air inlet pipe 23, part of the high-pressure gas will enter the grinding groove a101 through the pipe a, and part of the high-pressure gas will enter the grinding groove b24 through the pipe b. The high-pressure gas will cause the diamond grains in the grinding groove a101 to roll rapidly, and the rolling diamond grains will quickly rub the rust on the surface of the milling cutter, which can automatically realize the comprehensive grinding of the rust in the gaps between the teeth. At the same time, the cooled high-pressure airflow can cool the grinding area without water cooling, which saves water resources and avoids moisture on the processing table. The debris generated by grinding rolls upward with the diamond grains. When the debris rolls to the top, it is magnetically attracted to the surface of the end cover 3 under the action of the magnetic part 8 and is automatically recovered.

[0058] While the grinding operation is being performed in the grinding groove a101, the diamond grains in the area below the isolation block 14 gradually fall into the grinding groove b24 through the feed pipe. Under the blowing action of the high-pressure gas, the diamond grains in the grinding groove b24 flow at a high speed, so that the rust on the gap between the teeth on the surface of the milling cutter can be polished. The debris generated by the grinding enters the return pipe 11 with the diamond grains under the blowing action of the high-pressure gas, and flows back to the grinding groove a101 through the return pipe 11. The debris entering the grinding groove a101 will be magnetically moved by the magnetic member 8. The end cover 3 is adsorbed on the surface of the end cover 3 by force for recycling. When the debris and diamond grains in the grinding groove b24 all enter the grinding groove a101, the high-pressure air pump 6, the pump body and the vibration motor 7 are turned off, and the pressure relief valve 12 on the end cover 3 is used to release the high-pressure gas in the grinding groove a101. Then the end cover 3 is removed from the top of the upper seat 1, and the telescopic device 20 is controlled to make the extrusion component 10 move up and reset, so that the milling cutter can be removed, and then the magnetic part 8 is turned off, so that the debris adsorbed on the end cover 3 can be collectively dropped off, which is convenient for the recovery of the debris;

[0059] Finally, remove the lower seat 2 from the bottom end of the upper seat 1 and remove the milling cutter from the groove d901.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
