Technical Field

[0001] The present invention relates to the technical field of gear cutting, and particularly relates to a cutting device for machining gears of aircraft parts. Background Art

[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. Gears can be divided into parts such as teeth, tooth spaces, end faces, normal faces, addendum circles, dedendum circles, base circles, and pitch circles according to their structures. Commonly used steels for manufacturing gears include quenched and tempered steels, quenched steels, carburized and quenched steels, and nitrided steels. The process of obtaining the specific structure and accuracy of gears by mechanical methods. Gears are the core transmission components in aircraft parts, and the quality of their machining has a direct impact on the vibration noise and reliability of the aircraft assembly and even the whole machine, and sometimes becomes a key factor restricting the improvement of product level. The tooth profiles of various cylindrical gears and bevel gears can be manufactured by cutting or non-chip machining methods such as precision casting, precision forging, extrusion, and powder metallurgy. Gear cutting can be carried out by forming methods, profiling methods, generating methods, etc. according to the forming methods of the tooth profiles.

An upper inclined ring piece 203 is fixedly connected to the inner wall of the concave ring soft plate 201. An inner cleaning component 204 is fixedly connected to the outer surface of the upper inclined ring piece 203. A lower inclined ring piece 205 is fixedly connected to the inner wall of the concave ring soft plate 201. A bottom brush 206 is fixedly connected to the bottom of the lower inclined ring piece 205. A bottom surface round hole 207 is formed on the outer surface of the lower inclined ring piece 205. A plurality of cleaning groove mechanisms 6 are provided and evenly distributed on the outer surface of the fourteen-sided prism 5. Four electric push rods 3 are provided and evenly distributed at the bottom of the top cover 4. The top of the concave ring soft plate 201 is fixedly connected to the tooth hole cutter disc 1. Four middle arc holes 202 are provided and evenly distributed on the outer surface of the concave ring soft plate 201. A plurality of bottom brushes 206 are provided and evenly distributed at the bottom of the lower inclined ring piece 205. A plurality of bottom surface round holes 207 are provided and evenly distributed on the outer surface of the lower inclined ring piece 205;

[0025] The inner cleaning component 204 includes an arc-shaped side piece 2041. An upper round hole 2042 is formed on the outer surface of the arc-shaped side piece 2041. Wave-shaped connecting pieces 2043 are fixedly connected to both sides of the arc-shaped side piece 2041. Wave-shaped side holes 2044 are formed on the outer surface of the wave-shaped connecting pieces 2043. The bottom of the arc-shaped side piece 2041 is fixedly connected to the upper inclined ring piece 203. There are four arc-shaped side pieces 2041 which are evenly distributed on the upper inclined ring piece 203. There are multiple upper round holes 2042 which are evenly distributed on the arc-shaped side piece 2041. There are multiple wave-shaped side holes 2044 which are evenly distributed on the outer surface of the wave-shaped connecting pieces 2043. When in use, the circular workpiece 11 is fixed on the bottom column 10. The electric push rod 3 is started to push the toothed hole cutter disc 1 to move downward. When the toothed hole cutter disc 1 moves downward, it pushes the concave ring soft plate 201 to move downward. The bottom opening of the concave ring soft plate 201 faces outward and expands outward when it contacts the circular workpiece 11. When the bottom of the concave ring soft plate 201 expands outward, it slides and scrapes the top surface of the circular workpiece 11. When the concave ring soft plate 201 expands to wrap the circular workpiece 11 inside, at the same time, the lower inclined ring piece 205 on the inner wall of the concave ring soft plate 201 also starts to expand. When the lower inclined ring piece 205 expands, the bottom brush 206 at the bottom contacts the top surface of the circular workpiece 11, and the bottom brush 206 frictionally cleans the top surface of the circular workpiece 11. The circular workpiece 11 moves upward relative to the inside of the concave ring soft plate 201 and pushes the lower inclined ring piece 205 to expand upward and obliquely. When the lower inclined ring piece 205 expands upward and obliquely, a large amount of debris will inevitably accumulate in the area between the side close to the concave ring soft plate 201 and the concave ring soft plate 201. The debris sandwiched between the lower inclined ring piece 205 and the concave ring soft plate 201 drops downward through the bottom round hole 207. The upper inclined ring piece 203 and the lower inclined ring piece 205 expand their openings together with the expansion of the concave ring soft plate 201. At the same time, the circular workpiece 11 wrapped inside the concave ring soft plate 201 moves upward along the inner wall of the concave ring soft plate 201. The circular workpiece 11 pushes the lower inclined ring piece 205 to expand upward and open, and moves upward from the inner wall of the concave ring soft plate 201 to the bottom of the lower inclined ring piece 205, and moves upward along the bottom surface of the lower inclined ring piece 205 through the gradually expanding central opening of the lower inclined ring piece 205 and enters above the lower inclined ring piece 205. Similarly, the circular workpiece 11 pushes the upper inclined ring piece 203 to expand upward, and moves upward from the inner wall of the concave ring soft plate 201 to the inner wall of the upper inclined ring piece 203, and continues to move upward in the concave ring soft plate 201 along the inner wall of the upper inclined ring piece 203 through the central opening at the top of the upper inclined ring piece 203. When moving upward, it will contact and push the upper inclined ring piece 203 to expand outward. When the upper inclined ring piece 203 expands outward, it pushes the surrounding arc-shaped side pieces 2041 to bend and move outward. The arc-shaped side pieces 2041 are fixed on the outer surface of the upper inclined ring piece 203. The circular workpiece 11 passes through the upper inclined ring piece 203, that is, through the arc-shaped side pieces 2041, and finally contacts the toothed hole cutter disc 1 through the upper inclined ring piece 203 for cutting operation. After the circular workpiece 11 passes through the upper inclined ring piece 203, the top of the upper inclined ring piece 203 shrinks inward to form a conical shape. At this time, a large amount of debris cut off by the toothed hole cutter disc 1 will slide down through the conical setting on the outer side of the upper inclined ring piece 203.A large amount of debris that slides outward is discharged outward through the middle arc hole 202. When the upper inclined ring piece 203 expands outward, it drives the arc-shaped side piece 2041 on the outer surface to move outward together. When the arc-shaped side piece 2041 moves, it slides and scrapes the top inner wall of the concave ring soft plate 201. At the same time, the debris scraped by the arc-shaped side piece 2041 will fall downward through the upper round hole 2042 onto the upper inclined ring piece 203. When the arc-shaped side piece 2041 moves, it drives the waveform connecting pieces 2043 on both sides to stretch and move together. When the waveform connecting pieces 2043 stretch and move, they slide and scrape the top inner wall of the concave ring soft plate 201. At the same time, the debris scraped off by the waveform connecting pieces 2043 falls downward through the waveform side holes 2044.,

[0026] For the second embodiment, please refer to Figures 7 - 10 , the present invention provides a cutting device for machining gears of aircraft parts: the groove cleaning mechanism 6 includes a brush rod 601. An arc-shaped sleeve plate 602 is sleeved and fixedly connected to the outer surface of the brush rod 601. A side arc dial piece 603 is fixedly connected to one side of the arc-shaped sleeve plate 602. A bottom thorn block 604 is fixedly connected to the bottom of the side arc dial piece 603. An upper arc scraping piece 605 is fixedly connected to one side of the arc-shaped sleeve plate 602 close to the side arc dial piece 603. An arc surface round hole 606 is opened at the bottom of the upper arc scraping piece 605. One end of the brush rod 601 is fixedly connected to the fourteen-sided prism 5. A plurality of brush rods 601 are provided and evenly distributed on the outer surface of the fourteen-sided prism 5. A plurality of side arc dial pieces 603 are provided and evenly distributed on one side of the arc-shaped sleeve plate 602. A plurality of bottom thorn blocks 604 are provided and evenly distributed on the bottom of the side arc dial piece 603. A plurality of arc surface round holes 606 are provided and evenly distributed at the bottom of the upper arc scraping piece 605;

[0027] The external dial mechanism 7 includes a curved soft plate 701, both sides of the curved soft plate 701 are fixedly connected with side arc scrapers 702, one side of the curved soft plate 701 is fixedly connected with a corrugated ring piece 703, the outer surface of the corrugated ring piece 703 is provided with a corrugated arc hole 704, one side of the curved soft plate 701 is fixedly connected to the fourteen prism 5, and a plurality of corrugated arc holes 704 are arranged and evenly distributed on the outer surface of the corrugated ring piece 703. When in use, after the tooth hole cutter disc 1 cuts and forms the circular workpiece 11, the tooth hole cutter disc 1 is driven to move upward by the electric push rod 3, and the tooth hole cutter disc 1 moves upward. When the brush rod 601 on the outer surface of the fourteen-prism 5 contacts the tooth groove of the tooth hole cutter disc 1, the brush rod 601 frictionally cleans the inner groove of the tooth hole cutter disc 1, and a large amount of debris cleaned away falls downward through the arc surface circular hole 606 on the upper arc scraper 605. When the tooth hole cutter disc 1 continues to move upward, it pushes the side arc paddle 603 on one side of the arc sleeve plate 602 upward. When the side arc paddle 603 bends upward, it drives the bottom thorn block 604 to move upward together. When the bottom thorn block 604 moves upward, it breaks away from the contact with the brush on the brush rod 601. Until the tooth hole knife disk 1 moves downward, the side arc paddle 603 moves downward to drive the bottom thorn block 604 to pierce the brush on the brush rod 601 for combing. When the tooth hole knife disk 1 moves upward, it pushes and squeezes the curved soft plate 701. When the curved soft plate 701 is squeezed, it stretches outward. When the curved soft plate 701 stretches outward, it slides and scrapes the top surface of the tooth hole knife disk 1. When the curved soft plate moves, it drives the two sides The side arc scraper 702 moves together, and the side arc scraper 702 slides and scrapes the surface of the drive shaft of the electric push rod 3 when moving. At the same time, when the curved soft plate 701 is stretched and the bottom is about to contact the tooth hole cutter disc 1, the curved soft plate 701 and the tooth hole cutter disc 1 squeeze the waveform ring piece 703 together, and the waveform ring piece 703 on the inner wall of the curved soft plate 701 is squeezed and stretched to slide and scrape the area on the top surface of the tooth hole cutter disc 1 above the tooth hole. At the same time, the debris scraped by the waveform ring piece 703 and accidentally falling into the waveform gap falls downward through the waveform arc hole 704.

[0028] When the present invention is in operation, the circular workpiece 11 is fixed on the bottom column 10. The electric push rod 3 is started to push the tooth hole cutter disc 1 downward. When the tooth hole cutter disc 1 moves downward, it pushes the concave ring soft plate 201 downward. The bottom opening of the concave ring soft plate 201 faces outward and expands outward when it contacts the circular workpiece 11. When the bottom of the concave ring soft plate 201 expands outward, it slides and scrapes the top surface of the circular workpiece 11. When the concave ring soft plate 201 expands to wrap the circular workpiece 11, the lower inclined ring piece 205 on the inner wall of the concave ring soft plate 201 also starts to expand. When the lower inclined ring piece 205 expands, the bottom brush 206 at the bottom contacts the top surface of the circular workpiece 11, and the bottom brush 206 frictionally sweeps the top surface of the circular workpiece 11. The circular workpiece 11 moves upward relative to the inside of the concave ring soft plate 201 and pushes the lower inclined ring piece 205 to expand upward obliquely. When the lower inclined ring piece 205 expands upward obliquely, a large amount of debris is inevitably accumulated in the area between the side close to the concave ring soft plate 201 and the concave ring soft plate 201. The debris sandwiched between the lower inclined ring piece 205 and the concave ring soft plate 201 drops downward through the bottom circular hole 207. The circular workpiece 11 pushes the upper inclined ring piece 203 to expand and continues to move upward inside the concave ring soft plate 201. When moving upward, it contacts and pushes the upper inclined ring piece 203 to expand outward, and finally passes through the upper inclined ring piece 203 and contacts the tooth hole cutter disc 1 for cutting operation. After the circular workpiece 11 passes through the upper inclined ring piece 203, the top of the upper inclined ring piece 203 shrinks inward into a conical shape. At this time, a large amount of debris cut off by the tooth hole cutter disc 1 will slide down through the conical outer side of the upper inclined ring piece 203, and the large amount of debris sliding outward is discharged outward through the middle arc hole 202. When the upper inclined ring piece 203 expands outward, it drives the arc-shaped side piece 2041 on the outer surface to move outward together. When the arc-shaped side piece 2041 moves, it slides and scrapes the top inner wall of the concave ring soft plate 201. At the same time, the debris scraped by the arc-shaped side piece 2041 will drop downward through the upper circular hole 2042 onto the upper inclined ring piece 203. When the arc-shaped side piece 2041 moves, it drives the wave-shaped connecting pieces 2043 on both sides to stretch and move together. When the wave-shaped connecting pieces 2043 stretch and move, they slide and scrape the top inner wall of the concave ring soft plate 201. At the same time, the debris scraped off by the wave-shaped connecting pieces 2043 drops downward through the wave-shaped side holes 2044. After the tooth hole cutter disc 1 cuts and forms the circular workpiece 11, the electric push rod 3 drives the tooth hole cutter disc 1 to move upward. When the tooth hole cutter disc 1 moves upward, it contacts the upper arc scraper 605 on one side of the arc-shaped sleeve plate 602. The upper arc scraper 605 enters the tooth holes of the tooth hole cutter disc 1 and bends upward under the extrusion force. The upper arc scraper 605 slides and scrapes the inner wall of the tooth hole cutter disc 1. The brush rod 601 on the outer surface of the fourteen-sided prism 5 contacts the tooth grooves of the tooth hole cutter disc 1, and the brush rod 601 frictionally sweeps the inner grooves of the tooth hole cutter disc 1. A large amount of debris swept away drops downward through the arc surface circular hole 606 on the upper arc scraper 605. When the tooth hole cutter disc 1 continues to move upward, it pushes the side arc dial piece 603 on one side of the arc-shaped sleeve plate 602 to bend upward. When the side arc dial piece 603 bends upward, it drives the bottom thorn block 604 to move upward together.When the bottom thorn block 604 moves upward, it disengages from the contact with the brush on the brush rod 601. It is not until the tooth hole cutter disc 1 moves downward that the side arc deflector 603 deflects downward to drive the bottom thorn block 604 to pierce into the brush on the brush rod 601 for combing. When the tooth hole cutter disc 1 moves upward, it pushes and squeezes the curved flexible plate 701. When the curved flexible plate 701 is squeezed, it extends outward. When the curved flexible plate 701 extends outward, it slides and scrapes the top surface of the tooth hole cutter disc 1. When the curved flexible plate moves, it drives the side arc scraping pieces 702 on both sides to move together. When the side arc scraping pieces 702 move, they slide and scrape the surface of the drive shaft of the electric push rod 3. At the same time, when the bottom of the curved flexible plate 701 is about to contact the tooth hole cutter disc 1 when the curved flexible plate 701 extends, the curved flexible plate 701 and the tooth hole cutter disc 1 squeeze the corrugated ring piece 703 together. The corrugated ring piece 703 on the inner wall of the curved flexible plate 701 is squeezed and extended to slide and scrape the area of the top surface of the tooth hole cutter disc 1 above the tooth hole. At the same time, the debris that is scraped off by the corrugated ring piece 703 and accidentally falls between the corrugated gaps drops downward through the corrugated arc holes 704.,
