Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to a grinding process that can improve the tooth surface waviness. Background Art

[0002] A gear refers to a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. A standard gear refers to a gear with all parameters conforming to standard values, and standard gears for different uses are manufactured according to different standards. Tooth surface waviness refers to the periodic undulations formed by shape deviations caused by processing or use within a certain length range on the gear surface. Tooth surface waviness has an important impact on the transmission performance and service life of gears, and the higher the gear processing accuracy, the smaller the surface waviness.

[0003] Common gear grinding equipment, when in use, clamps and fixes a single gear and then directly grinds the surface and tooth grooves of the gear through a grinding tool. However, when in use, the outer wall of the gear is arc-shaped, and the grinding angles of the tooth grooves of the gear are not the same, which increases the grinding accuracy of the gear surface and tooth grooves. Existing grinding equipment will frequently replace the grinding tool according to the changes in the grinding position and angle of the gear, and cannot grind multiple gears simultaneously, resulting in low gear grinding efficiency. At the same time, when in use, it is unable to polish the surface of the ground gear in a timely manner, and subsequent unified polishing and processing are required after the gear grinding is completed, reducing the production efficiency of the gear. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art and propose a grinding process that can improve the tooth surface waviness.

[0016] Preferably, a limiting plate is installed at the end of the second electric slider away from the inside of the protective plate. The limiting plate is slidably installed on the outer wall of the protective plate.

[0020] Preferably, fixing holes are formed at the tops of both ends of the support frame. The four baffles are respectively located at both ends inside the machine body. A limiting block is installed on the side surface of the rotating disk, and the limiting block is located on the side surface of the fixing plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] In the present invention, the positions of the gear column and the grinding tool can be adjusted in real time. Therefore, gears with different diameters and thicknesses can be ground and processed during use, and a large number of gears can be installed on the threaded rod according to its length. It is convenient for a number of first electric sliders and the grinding tool to sequentially perform grinding on multiple gears at different degrees and angles during movement. A number of internal thread blocks are used to fix the positions of a number of gears to be processed. At the same time, when in use, the tooth groove directions of a number of gears are the same, which is convenient for the staff to simultaneously grind the outer walls and tooth grooves of a number of gears, improving the grinding efficiency of the gears.

[0023] In the present invention, the gear column is meshed and connected with a number of gears during use. When the motor stops rotating the mounting rod, the gear column can simultaneously fix the positions of a number of gears through the meshing connection, preventing the gears from rotating during grinding. Moreover, a polishing sleeve is installed on the outer wall of the gear column, and the polishing sleeve is located between the contact positions of the gear column and the gears. During use, the polishing sleeve can play a good role in protecting the contact surface between the gear column and the gears, preventing indentations from appearing on the outer walls and tooth grooves of the gears due to the mutual extrusion of the contact surfaces between the gears and the gear column during gear grinding, and facilitating direct grinding of the gears after the positions of the two mounting rods are moved.

[0024] In the present invention, the third electric slider can drive the gear column to reciprocate on the outer wall of the mounting rod. Internal thread blocks are provided on both sides of the gear on the outer wall of the threaded rod. When the gear column slides, it will not drive the gear to move, and the gear column can still fix the position of the gear, preventing the gear from rotating at an angle. When the gear column slides, it can drive the polishing sleeve to slide on the ground outer wall and the inner wall of the tooth groove of the gear. When the polishing sleeve slides, it can polish the ground positions of the outer wall and the inner wall of the tooth groove of the gear, reducing the roughness of the outer wall and the inner wall of the tooth groove of the gear and improving the surface precision of the gear.

[0025] In the present invention, when in use, the electric rotating shaft can not only drive the protection plate to rotate through the fixing plate and the connecting plate, but also support the protection plate through the rotating disc, the adjusting plate and the connecting plate. After grinding the designated positions on the outer walls of several gears, the motor can drive the gear column to rotate through the mounting rod, and adjust the angles of several gears through the meshing connection between the gear column and several gears, facilitating the grinding of the remaining positions on the outer walls of several gears by several grinding knives again.

[0044] As a technical optimization solution of the present invention, baffles 14 are installed at both ends of the inner walls of the two protective plates 3. Guide holes 30 are formed on the sides of the two baffles 14. An installation groove 22 is formed on the side of one of the baffles 14 away from the inside of the protective plate 3. The installation groove 22 is connected to the guide hole 30. Installation rods 12 are installed inside the two protective plates 3. Both ends of the installation rod 12 are movably installed inside the guide holes 30 on the two baffles 14 respectively; during use, the guide holes 30 can limit and guide the moving direction of the installation rod 12, facilitating the gear column 24 to better limit the position of the gear, and at the same time facilitating the grinding sleeve 25 to grind the outer wall and tooth grooves of the gear, and the grinding cutter 9 can also better grind the outer wall and the inner wall of the tooth grooves of the gear.

[0045] As a technical optimization solution of the present invention, a motor 23 is slidably installed inside the installation groove 22. One end of the output shaft of the motor 23 close to the inside of the protective plate 3 is connected to one end of the installation rod 12 through a coupling. A gear column 24 is slidably installed on the outer wall of one of the installation rods 12, and a plurality of first electric sliders 20 are slidably installed on the outer wall of the other installation rod 12. A grinding cutter 9 is installed at one end of the first electric slider 20, and a grinding sleeve 25 is installed on the outer wall of the gear column 24; during use, the plurality of first electric sliders 20 can drive the plurality of grinding cutters 9 of different shapes to move respectively, facilitating the plurality of grinding cutters 9 to perform grinding on the outer wall and tooth grooves of the gear at different degrees and angles in sequence during movement.

[0046] As a technical optimization solution of the present invention, connection blocks 27 are rotatably installed on the outer walls of both ends of the installation rod 12. The two connection blocks 27 are respectively located between the two baffles 14. A sliding hole 4 is formed on the outer wall of the protective plate 3 along the length direction. Second electric sliders 28 are slidably installed at both ends inside the sliding hole 4. One end of the second electric slider 28 is rotatably installed with a connecting rod 29. The end of the connecting rod 29 away from the second electric slider 28 is rotatably connected to the connection block 27; when the second electric slider 28 moves, the installation rod 12 can be pushed and pulled through the connecting rod 29 and the connection block 27, and during use, in cooperation with the guide hole 30, the precise position adjustment of the installation rod 12 can be achieved.

[0047] As a technical optimization solution of the present invention, a limiting plate 26 is installed at one end of the second electric slider 28 away from the inside of the protective plate 3. The limiting plate 26 is slidably installed on the outer wall of the protective plate 3. On the inner walls of the two protective plates 3 near one end of the opposite side, a plurality of top plates 15 are installed along the length direction. A plurality of nozzles 21 are installed at the bottom of the top plate 15. During use, one end of the top plate 15 is connected to an external coolant delivery pipe through a connection port, and the coolant delivery pipe is communicated with a plurality of nozzles 21 through the top plate 15. When in use, the coolant is sprayed on the surface of the gear through the nozzles 21, which can play a good cooling and protection role for the gear and the grinding tool 9 when the grinding tool 9 grinds the gear.

[0048] As a technical optimization solution of the present invention, three-jaw chucks 16 are installed on the inner walls at both ends of the machine body 1. A threaded rod 11 is installed inside the machine body 1. The two ends of the threaded rod 11 are respectively located inside the two three-jaw chucks 16. A plurality of gears are installed on the outer wall of the threaded rod 11. The three-jaw chuck 16 can play a good position-limiting and clamping role for the two ends of the threaded rod 11 during use. The three-jaw chuck 16 cooperates with the gear column 24 to make the threaded rod 11 and the gears more stable during use.

[0049] As a technical optimization solution of the present invention, internal thread blocks 19 are threadedly installed between adjacent two gears on the outer wall of the threaded rod 11. The threaded rod 11 and a plurality of gears are both located between the two protective plates 3. The gear column 24 is meshed and connected with a plurality of gears. The side surface of the grinding sleeve 25 abuts against the outer wall of the gear and the inner wall of the tooth groove. When the installation rod 12 drives the gear column 24 to rotate, the gear column 24 can drive a plurality of gears to rotate synchronously through the meshing connection with a plurality of gears, which is convenient for adjusting the angle of the gear and facilitating the grinding tool 9 to grind the tooth grooves at different positions on the outer wall of the gear.

[0050] As a technical optimization solution of the present invention, a groove 32 is opened on the inner wall of the gear column 24. A third electric slider 33 is installed on the inner wall of the groove 32. The third electric slider 33 is slidably installed on the outer wall of the installation rod 12. The third electric slider 33 can drive the gear column 24 to slide on the outer wall of the installation rod 12 during use. At the same time, the gear column 24 grinds the inner wall of the tooth groove on the outer wall of the gear that has been ground through the grinding sleeve 25 on its outer wall.

[0051] As a technical optimization solution of the present invention, fixing holes 17 are opened at the top of both ends of the support frame 2. Four baffle plates 14 are respectively located at both ends inside the machine body 1. A limiting block is installed on the side surface of the rotating disc 31. The limiting block is located on the side surface of the fixing plate 7. During use, the staff can install fixing bolts in the fixing holes 17 to fix the support frame 2 and the machine body 1 to the ground through the fixing bolts, improving the stability performance of the machine body 1 during use.

[0052] When the present invention is in use, the staff installs a number of gears to be processed on the outer wall of the threaded rod 11, and internally threaded blocks 19 are threadedly installed on the outer wall of the threaded rod 11 between adjacent two gears. At the same time, internally threaded blocks 19 are threadedly installed at both ends of the outer wall of the threaded rod 11, so that both sides of the gears are in contact with the side surfaces of the internally threaded blocks 19. When in use, the positions of a number of gears to be processed can be fixed by a number of internally threaded blocks 19. At the same time, when in use, the tooth groove directions of a number of gears are the same, which is convenient for the staff to grind the outer walls and tooth grooves of a number of gears simultaneously, improving the grinding efficiency of the gears.

[0053] The staff places the threaded rod 11 installed with gears and internally threaded blocks 19 inside the machine body 1, and both ends of the threaded rod 11 are respectively located inside the three-jaw chucks 16 on the inner walls at both ends of the machine body 1. The two three-jaw chucks 16 clamp and support both ends of the threaded rod 11. The electric rotating shafts 13 on the sides of the two support frames 2 drive the two protective plates 3 to rotate respectively through the fixing plates 7 and the connecting plates 6. At the same time, the end of the protective plate 3 away from the fixing plate 7 drives the rotating disk 31 to rotate on the outer wall of the electric rotating shaft 13 through the connecting plate 6 and the adjusting plate 8. When in use, the electric rotating shaft 13 can not only drive the protective plate 3 to rotate through the fixing plate 7 and the connecting plate 6, but also support the protective plate 3 through the rotating disk 31, the adjusting plate 8 and the connecting plate 6.

[0054] When in use, the two protective plates 3 respectively rotate to both sides of the top of the machine body 1, and the opposite surfaces at the tops of the two protective plates 3 are in contact with each other. When in use, the two protective plates 3 and the machine body 1 cooperate with each other to provide good shielding for the inside of the machine body 1, preventing iron filings from splashing when the gears are being ground. When the two protective plates 3 rotate, they can drive the mounting rods 12 inside them to move in position, so that the two mounting rods 12 respectively move to both sides above the gears. The second electric slider 28 slides inside the sliding hole 4 on the outer wall of the protective plate 3 and drives one end of the connecting rod 29 close to the inner wall of the protective plate 3 to move. When the connecting rod 29 moves, the end away from the inner wall of the protective plate 3 can push the connecting block 27 on the outer wall of the mounting rod 12, driving the mounting rod 12 to move towards the gear through the connecting block 27. When in use, the position of the mounting rod 12 can be adjusted according to the actual situation.

[0055] Since both ends of the mounting rod 12 are respectively located inside the guiding holes 30 on the baffle plates 14 at both ends of the protection plate 3, and the rotation axes of the electric rotating shaft 13 and the threaded rod 11 are at the same horizontal height position, when the mounting rod 12 moves, the guiding holes 30 can play a good guiding role in the movement of the mounting rod 12, enabling the gear column 24 on one of the mounting rods 12 to accurately mesh and connect with the gear, and the grinding tool 9 on the other mounting rod 12 can accurately grind the outer wall and tooth grooves of the gear. During use, since the positions of the gear column 24 and the grinding tool 9 can be adjusted in real time, gears with different diameters and thicknesses can be ground and processed during use, and a large number of gears can be installed on the threaded rod 11 according to its length, facilitating the simultaneous grinding of multiple gears at different degrees and angles by a number of first electric sliders 20 and the grinding tool 9 during movement.

[0056] When the mounting rod 12 moves, the motor 23 can drive the mounting rod 12 to rotate, enabling the two mounting rods 12 to respectively adjust the angles of the gear column 24 and the grinding tool 9 thereon, so that the gear column 24 can directly mesh and connect with a number of gears after moving to the designated position, and the grinding tool 9 can accurately move to the corresponding positions of the outer wall and tooth grooves of the gear. During use, the gear column 24 meshes and connects with a number of gears. When the motor 23 stops rotating the mounting rod 12, the gear column 24 can simultaneously fix the positions of a number of gears through meshing connection, preventing the gears from rotating during grinding. Moreover, a polishing sleeve 25 is installed on the outer wall of the gear column 24, and the polishing sleeve 25 is located between the contact positions of the gear column 24 and the gear. During use, the polishing sleeve 25 can play a good role in protecting the contact surface between the gear column 24 and the gear, preventing indentations from appearing on the outer wall and tooth grooves of the gear due to the mutual extrusion of the contact surfaces between the gear and the gear column 24 during gear grinding, and facilitating the direct grinding of the gear after the positions of the two mounting rods 12 are moved.

[0057] The top plate 15 is connected to the external coolant delivery pipe through the connection port, and the coolant delivery pipe is interconnected with a number of nozzles 21 through the top plate 15. When the staff grinds the gears, the coolant delivery pipe can flow the coolant from above the gears to the surface of the gears through the number of nozzles 21, cooling the gears and the grinding tool 9 through the coolant. At the same time, the coolant cleans the iron filings on the surfaces of the gears, the grinding tool 9 and the polishing sleeve 25. And a number of first electric sliders 20 drive the grinding tool 9 thereon to move sequentially from one end of the mounting rod 12 to the other end, and when the number of grinding tools 9 move, they sequentially grind the outer walls and the inner walls of the tooth grooves at the specified positions on the surfaces of the number of gears. When the grinding of the specified positions on the outer walls of the number of gears is completed, the motor 23 can drive the gear column 24 to rotate through the mounting rod 12, and adjust the angles of the number of gears through the meshing connection between the gear column 24 and the number of gears, facilitating the number of grinding tools 9 to grind the remaining positions on the outer walls of the number of gears again.

[0058] When the positions where the number of gears are ground are rotated to the side close to the gear column 24 and are meshed with the gear column 24, the third electric slider 33 can drive the gear column 24 to slide reciprocally on the outer wall of the mounting rod 12. Since internal thread blocks 19 are provided on both sides of the gear on the outer wall of the threaded rod 11, when the gear column 24 slides, it will not drive the gear to move, and the gear column 24 can still fix the position of the gear, preventing the gear from rotating at an angle. When the gear column 24 slides, it can drive the polishing sleeve 25 to slide on the outer wall and the inner wall of the tooth groove where the gear is ground. When the polishing sleeve 25 slides, it can polish the ground positions on the outer wall and the inner wall of the tooth groove of the gear, reducing the roughness of the outer wall and the inner wall of the tooth groove of the gear and improving the surface precision of the gear.

[0059] The iron filings generated when the gears are ground and polished can fall to the inner bottom of the machine body 1. The fine iron filings on the gear surface will also flow into the interior of the machine body 1 through the coolant and flow to the outside through the discharge hole 10. The staff can place a collection and filtration device below the machine body 1 outside to filter the coolant and the iron filings, enabling the coolant to be recycled and collecting the iron filings at the same time. When the gears are ground and polished, the second electric slider 28 drives the mounting rod 12 to move towards the inner wall direction of the protective plate 3, and the electric rotating shaft 13 drives the two protective plates 3 to move to both sides of the machine body 1. At the same time, the two three-jaw chucks 16 disconnect the clamping of both ends of the threaded rod 11, and the staff can take the threaded rod 11 and disassemble the gears thereon.

[0060] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
