[0002] In the modern machinery industry, gears are important transmission components, and their precision and quality directly affect the performance and reliability of the entire mechanical equipment. Gear grinding technology can achieve high-precision gear manufacturing, meet the accuracy requirements of gear modulus, pressure angle and other parameters, and ensure that the gears run smoothly and efficiently during the transmission process. The gear tooth surface after grinding has low surface roughness and high finish, which reduces friction and wear between the tooth surfaces. This not only extends the service life of the gear, but also improves the reliability and stability of the entire mechanical equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The driving wheel is driven by the second motor to rotate, and the driving wheel drives the grinding wheel to rotate to grind the inner gear ring. When the grinding wheel is worn, the electric push rod pushes the driving wheel so that the driving block is no longer plugged into the sliding square groove. Then the motor three drives the rotating ring to rotate 180 degrees, so that the two rotating plates are swapped. Then the driving block is inserted into the sliding square groove again, and the driving grinding wheel is then rotated to grind the inner gear ring, so that a new grinding disc can be quickly switched, which improves work efficiency.

[0016] 2. The threaded rod is driven to rotate by the motor, so that the threaded rod is pushed toward the push rod. When the cross plate is inserted into the gap between the four push rods, the cross plate will drive the locking rod to continue to rotate. At the same time, the cross plate pushes the square push block to move. The square push block moves and pushes the sliding block, so that the engaging block is pulled by the connecting rope to slide toward the sliding square groove. After the engaging block is completely immersed in the cavity of the sliding groove, the engaging groove will be resisted again. Then the elastic restoring force of the spring three will push the grinding wheel out of the outer wall of the locking rod, so that the grinding disc can be quickly disassembled.

[0017] 3. A new grinding wheel is carried by the magnetic ring and mounted on the outer wall of the locking rod. Then the cross plate starts to rotate in the opposite direction. Through the contact between the cross plate and the side surface of the push rod, the cross plate drives the locking rod to rotate. The grinding wheel is adsorbed by the magnetic ring and will not rotate with it. During the rotation of the locking rod, the engaging block will be inserted into the engaging groove. At this time, the magnetic ring will be separated from the adsorption of the grinding wheel and reset. Then the cross plate will also be separated from the push rod during the rotation. At the same time, the locking rod can be calibrated and positioned during the rotation of the cross plate, so as to facilitate the driving block to connect with the square groove again.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 10The present invention provides a technical solution: a planetary reducer gear grinding device, comprising a workbench 1, a U-shaped sliding groove 2 is provided at the upper end of the workbench 1, a mechanical arm 3 is slidably connected to the inner wall of the U-shaped sliding groove 2, a clamping structure is welded to the upper end of the U-shaped sliding groove 2, an inner gear ring 4 is clamped on one side of the clamping structure, a connecting column 5 is fixedly installed at the upper end of the mechanical arm 3, a positioning column 6 is fixedly installed at the end of the connecting column 5 away from the mechanical arm 3, and a rotating shaft 3 is rotatably connected to the outer wall of the positioning column 6 The rotating ring 7 has two symmetrically distributed rotating plates 8 fixedly connected on both sides of the rotating ring 7. The end of each rotating plate 8 away from the rotating ring 7 is rotatably connected to a driven wheel 9, and the driven wheel 9 is embedded in the inner wall of the rotating plate 8. A locking rod 10 is fixedly installed on one end of the driven wheel 9. A grinding wheel 11 is sleeved on the outer wall of the locking rod 10. Four fitting grooves 12 are evenly spaced on the inner wall of the grinding wheel 11. The grinding wheel 11 is a bevel groove. The side away from the locking rod 10 is a bevel, and the side close to the locking rod 10 is Straight edge, the outer wall of the locking rod 10 is provided with a clamping structure, one side of the driven wheel 9 is slidably connected with four push rods 22, each push rod 22 is sleeved with a spring 3 23 at one end close to the grinding wheel 11, the driven wheel 9 and the locking rod 10 are penetrated by the center to open a sliding square groove 15, the sliding square groove 15 is slidably connected with a square push block 17 at one end close to the driven wheel 9, the outer wall of the square push block 17 is sleeved with a spring 2 18, and the spring 2 18 is in conflict with the outer wall of the driven wheel 9, through the square push block 17 The square push block 17 applies pressure to make the square push block 17 slide inside the sliding square groove 15. At the same time, when the square push block 17 is no longer under pressure, the square push block 17 is reset by the elastic restoring force of the spring 2 18. The motor 38 is embedded and installed on the side of the connecting column 5 close to the rotating plate 8. The output end of the motor 38 is sleeved with a transmission belt 2 39. The other end of the transmission belt 2 39 is sleeved on the outer wall of the rotating ring 7. The transmission belt 2 39 can make the motor 38 drive the rotating ring 7 to rotate;

[0033] Specifically, Figure 5 As shown, baffles are evenly provided at both ends of the push rod 22, and the push rod 22 can slide back and forth inside the driven wheel 9, and the spring three 23 resists the baffles to make the push rod 22 slide toward the locking rod 10. When the grinding wheel 11 is clamped on the outer wall of the locking rod 10, the spring three 23 will be compressed, and the push rod 22 will be pushed to one side of the square push block 17, so that the nut seat 20 is flush with the square push block 17.

[0034] Among them, the clamping structure includes four sliding grooves 13, and the sliding grooves 13 are evenly spaced on the outer wall of the locking rod 10. The inner wall of each sliding groove 13 is slidably connected with a fitting block 131, and each fitting block 131 can be inserted into the fitting groove 12 at the corresponding position. A spring 132 is fixedly installed between the lower end of each fitting block 131 and the bottom of the inner cavity of the sliding groove 13. The interior of the sliding square groove 15 is slidably connected with a sliding block 16, and the sliding block 16 is in contact with the square push block 17. Four connecting ropes 14 are evenly spaced on the outer wall of the sliding block 16, and each connecting rope 14 is fixedly connected to the fitting block 131 at the corresponding position. The inner wall of the sliding square groove 15 is provided with a wire groove 141 for the connecting rope 14 to slide.

[0035] Specifically, the side of the engaging block 131 close to the driven wheel 9 is a straight edge, and the side away from the driven wheel 9 is a beveled edge. When the workbench 1 is sleeved on the outer surface of the locking rod 10 and pushed in the direction of the driven wheel 9, the beveled edge of the engaging block 131 will be easy to contact with the notch of the grinding wheel 11 and interfere with the beveled edge of the engaging block 131, so that the engaging block 131 slides in the direction of the sliding square groove 15. At the same time, the spring 132 will be compressed. At this time, the grinding wheel 11 passes over the engaging block 131 and is sleeved on the outer surface of the locking rod 10. When the engaging block 131 is aligned with the engaging groove 12 on the inner wall of the grinding wheel 11, the engaging block 131 is inserted into the inside of the engaging groove 12 under the thrust of the elastic recovery of the spring 132. At the same time, the engaging groove 12 and the beveled edge of the engaging block 131 close to the driven wheel 9 will interfere with each other, so that the spring 3 23 cannot push the engaging block 131 out of the outer wall of the locking rod 10.

[0036] Among them, an L-shaped connecting frame 19 is fixedly installed on one side of the connecting column 5, and the L-shaped connecting frame 19 is located on the side away from the inner gear ring 4. A nut seat 20 is embedded and installed on the outer surface of the L-shaped connecting frame 19. A threaded rod 21 is threadedly connected to the inner wall of the nut seat 20. A cross plate 211 is slidably connected to the end of the threaded rod 21 close to the rotating plate 8. A spring four 24 is fixedly connected between the cross plate 211 and the threaded rod 21. The cross plate 211 can be inserted between the four push rods 22. A motor 27 is fixedly installed on the outer side wall of the L-shaped connecting frame 19, and a transmission wheel 28 is fixedly installed on the output end of the motor 1 27. A straight-line slide rod 25 is slidably connected to the end of the threaded rod 21 away from the cross plate 211. A transmission wheel 26 is fixedly installed on one end of the straight-line slide rod 25, and a belt 29 is commonly sleeved between the transmission wheel 1 26 and the transmission wheel 2 28.

[0037] Specifically, when the motor 1 27 is started, it drives the transmission wheel 28 to rotate, and the transmission wheel 28 drives the transmission wheel 1 26 to rotate through the belt 1 29. When the transmission wheel 1 26 rotates, the straight slide bar 25 rotates inside the threaded rod 21. Because the straight slide bar 25 is a straight square, when the straight slide bar 25 rotates, it drives the threaded rod 21 to rotate inside the nut seat 20. Through the threaded connection, the threaded rod 21 can be extended and retracted during the rotation. At the same time, the straight slide bar 25 will always be in place and will not move with the threaded rod 21. When the threaded rod 21 rotates, the cross plate 211 will move toward the push rod 22 and the square push block 17. At this time, the push rod 22 is affected by the grinding wheel 11. When the cross plate 211 contacts the front of the push rod 22, in order to prevent hard contact, the cross plate 211 will slide in the direction of the threaded rod 21, and the spring four 24 will be compressed. Then, as the threaded rod 21 rotates, the cross plate 211 will inevitably insert into the gap between the four push rods 22 within a rotation of ninety degrees. At this time, the cross plate 211 will contact the side surface of the push rod 22 and drive the push rod 22 to rotate. When the push rod 22 rotates, the locking rod 10 will also rotate with it. The number of rotations of the threaded rod 21 is a fixed number of circles. When the rotation is completed, the locking rod 10 will be carried and rotated to the specified position, which is convenient for the installation of the grinding wheel 11. At the same time, as the cross plate 211 pushes the square push block 17, as shown in FIG. Figure 6 As shown, the square push block 17 will push the sliding block 16. The sliding of the sliding block 16 will stretch the connecting rope 14, and the connecting rope 14 will be pulled into the inside of the wire groove 141. At the same time, the engaging block 131 will be pulled to the bottom of the inner cavity of the sliding groove 13, so that the engaging block 131 can no longer interfere with the engaging groove 12. Then, the elastic restoring force of the spring three 23 will push out the worn grinding wheel 11, and the grinding wheel 11 will slide off the locking rod 10.

[0038] Among them, the end of the positioning column 6 away from the rotating ring 7 is slidably connected to the electric push rod 30, and the output end of the electric push rod 30 is fixedly installed with a mounting disk 31. A driving frame 33 is welded on the side of the mounting disk 31 close to the inner gear ring 4, and the end of the driving frame 33 away from the mounting disk 31 is rotatably connected to the driving wheel 34, and the side of the driving wheel 34 close to the locking rod 10 is slidably connected to the driving block 36, and the driving block 36 can be inserted into the interior of the sliding square groove 15, and a spring five 37 is fixedly installed between the driving block 36 and the driving wheel 34, and a motor two 32 is embedded and installed on the side of the mounting disk 31 away from the electric push rod 30, and a transmission belt one 35 is sleeved on the output end of the motor two 32, and the other end of the transmission belt one 35 is sleeved on the outer wall of the driving wheel 34.

[0039] Specifically, the electric push rod 30 pushes the driving frame 33, so that the driving wheel 34 contacts one end of the locking rod 10, and the driving block 36 is inserted into the sliding square groove 15. Since the sliding square groove 15 and the driving block 36 are both square, the motor 2 32 can be started to drive the driving wheel 34 to rotate through the transmission belt 1 35. While the driving wheel 34 rotates, the locking rod 10 can be driven to rotate on the rotating plate 8 through the connection between the driving block 36 and the sliding square groove 15. The rotation of the locking rod 10 drives the grinding wheel 11 to rotate. At the same time, in order to prevent the driving block 36 from hard contact with the surface of the locking rod 10, when the driving block 36 rotates and fails to insert into the sliding square groove 15, the spring 5 37 will be compressed, and then the driving block 36 and the sliding square groove 15 are matched through the rotation of the driving wheel 34, and then the spring 5 37 pushes the driving block 36 into the sliding square groove 15.

[0040] Among them, a disk storage bin 40 is fixedly installed on one side of the L-shaped connecting frame 19, and a cylinder 1 41 is fixedly installed on the side of the disk storage bin 40 away from the L-shaped connecting frame 19, and a magnetic ring 42 is fixedly installed on the output end of the cylinder 1 41. The magnetic ring 42 is slidably connected inside the disk storage bin 40, and the magnetic ring 42 can be sleeved on the outer wall of the locking rod 10. The clamping structure includes a rotating frame 43, and a clamping platform 44 is installed on one side of the rotating frame 43. A plurality of cylinders 2 45 are installed on the outer wall of the clamping platform 44, and the cylinders 2 45 are distributed in a ring shape, and a clamping plate 46 is fixedly installed on the output end of the cylinder 2 45, and the inner gear ring 4 is clamped between each clamping plate 46. The rotating frame 43 can drive the clamping platform 44 to rotate so that the position of the inner gear ring 4 can be adjusted to facilitate the grinding of the gear teeth. The mechanical arm 3 can slide on the inner wall of the U-shaped sliding groove 2, thereby adjusting the position of the grinding wheel 11, and the mechanical arm 3 can adjust the angle of the grinding wheel 11.

[0041] Specifically, a slot for placing the grinding wheel 11 is provided at the upper end of the disk storage bin 40, and a slot for transporting the grinding wheel 11 is provided in the disk storage bin 40 close to the rotating plate 8. When the grinding wheel 11 is placed from the upper slot of the disk storage bin 40, the side of the grinding wheel 11 will be attracted by the magnetic ring 42, and then the magnetic ring 42 is pushed by the cylinder 1 41, and the magnetic ring 42 carries the grinding wheel 11 and pushes it in the direction of the locking rod 10. At this time, the worn grinding wheel 11 sleeved on the outer wall of the locking rod 10 has been pushed out by the spring 3 23. At this time, the magnetic ring 42 pushes the grinding wheel 11 to be sleeved on the locking rod 10, and then the cross plate 211 rotates in the opposite direction to drive the locking rod 10 to rotate. During the rotation, the cross plate 211 will gradually move away from the square Push block 17, so that spring 2 18 drives square push block 17 to reset in the direction away from locking rod 10, then sliding block 16 is no longer resisted, spring 132 will push engaging block 131 to reset, if engaging block 131 conflicts with the inner side wall of grinding wheel 11, cross plate 211 will still conflict with push rod 22 and drive locking rod 10 to rotate a certain distance, at the same time, grinding wheel 11 is magnetically attracted by magnetic ring 42 and cannot rotate because of the friction between the two surfaces, finally engaging block 131 is inserted into the inside of engaging groove 12, at this time, engaging groove 12 is fixed on the outer side wall of locking rod 10, magnetic ring 42 can be retracted, at the same time, cross plate 211 is separated from between push rod 22 during rotation.

[0042] The specific working principle and use method of the present invention are explained in detail below: the clamping plate 46 is pushed by the cylinder 2 45 so that the inner gear ring 4 is clamped on one side of the clamping platform 44, and then the grinding wheel 11 is driven by the mechanical arm 3 to move in the direction of the inner gear ring 4, and at the same time, the motor 2 32 drives the driving wheel 34 to rotate, and the driving wheel 34 drives the grinding wheel 11 to rotate. When the grinding wheel 11 is worn, the electric push rod 30 pushes the driving wheel 34 so that the driving block 36 is no longer plugged into the sliding square groove 15, and then the motor 3 38 drives the rotating ring 7 to rotate 180 degrees, so that the two rotating plates 8 are exchanged, and then the driving block 36 is inserted into the sliding square groove 15 again, and the driving grinding wheel 11 is then rotated to grind the inner gear ring 4, thereby improving the working efficiency;

[0043] Then the motor 1 27 drives the threaded rod 21 to rotate, so that the threaded rod 21 is pushed toward the push rod 22. When the cross plate 211 is inserted into the gap between the four push rods 22, the cross plate 211 drives the locking rod 10 to continue rotating. At the same time, the cross plate 211 pushes the square push block 17 to move. The square push block 17 moves and pushes the sliding square block 16, so that the engaging block 131 is pulled by the connecting rope 14 to slide toward the sliding square groove 15. After the engaging block 131 is completely immersed in the cavity of the sliding groove 13, the engaging groove 12 will be resisted again. Then the elastic restoring force of the spring 3 23 will push the grinding wheel 11 out of the outer wall of the locking rod 10.

[0044] Finally, the new grinding wheel 11 is carried by the magnetic ring 42 and sleeved on the outer wall of the locking rod 10, and then the cross plate 211 starts to rotate in the opposite direction. Through the interference between the cross plate 211 and the side surface of the push rod 22, the cross plate 211 drives the locking rod 10 to rotate, and the grinding wheel 11 is adsorbed by the magnetic ring 42 and will not rotate with it. During the rotation of the locking rod 10, the engaging block 131 will be inserted into the engaging groove 12, at which time the magnetic ring 42 will be separated from the adsorption of the grinding wheel 11 and reset, and then the cross plate 211 will also be separated from the push rod 22 during the rotation, thereby achieving rapid replacement of the grinding wheel 11.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
