[0002] As an important transmission component, face gears are widely used in high-end equipment manufacturing fields such as aviation, automobiles, and engineering machinery. The processing quality of their tooth surfaces has an important impact on the stability, noise control, and service life of the transmission system. The face gears are connected and installed through the mounting holes in the middle of the face gears with keyways, splines, or tapered holes. In the manufacture of small face gears, the face gears are usually ground using a grinding disc in a grinding CNC machine tool. Therefore, grinding is a key step in improving tooth surface accuracy and surface quality.

[0014] Beneficial effects of the present invention:

[0015] 1. A CNC machining device and machining method for face gears. When the second cam in the loading and unloading mechanism rotates, the upper and lower sliding plates are driven to slide reciprocatingly up and down on the side walls of the reciprocating plate. Subsequently, the upper and lower sliding plates drive the inner circular block to clamp the opposite gear through the picking plate, so that it leaves the top of the conveyor belt, thereby realizing the motion trajectory of driving the inner circular block to move up and down to pick up the material. Then, the first cam rotates to drive the reciprocating plate to slide left and right between the first slide plate. When the reciprocating plate slides, it drives the inner circular block clamping the face gear to move to the top of the grinding table and place it. When the first cam continues to rotate, it drives the picking plate and the inner circular block to return to the original path and continue to clamp the gear at the top of the conveyor belt. At the same time, it also drives the semicircular plate to squeeze and clamp the opposite gear. After clamping, the gear can be ground. After grinding, when the material is loaded again through the inner circular block, it drives the semicircular plate clamping the gear to move to the conveyor belt on the other side, and is squeezed by the squeezing plate to thereby The material can be unloaded, thus realizing a fully automated loading and unloading process, completely getting rid of manual intervention, and solving the problem that the face gears need to be placed one by one on the processing platform by the operator and manually removed after the processing is completed. This not only increases the workload of the operator, but also significantly reduces the overall production efficiency. At the same time, manual loading also leads to inaccurate positioning of the workpiece, thereby affecting the processing accuracy. The operator only needs to place the gear to be processed on one end of the conveyor belt, and the equipment can transport the gear to the top of the grinding table through the loading and unloading mechanism. This automated operation not only greatly reduces the labor intensity of the operator, but also significantly improves production efficiency, especially in large-scale processing scenarios. The entire processing process can be completed at a stable and efficient rhythm. At the same time, manual loading also avoids the impact of manual placement of face gears on processing accuracy, thereby achieving reliable limiting of the gears and ensuring the stability and consistency of the processing process.

[0016] 2. The CNC machining device and machining method for face gears, when loading materials, will drive the scraper plate in the anti-clogging mechanism to scrape the debris on the top of the filter screen to the storage tank for centralized processing, avoiding the blockage of the filter screen due to impurities or debris, resulting in poor water flow and reduced filtration efficiency, thereby ensuring smooth water flow.

Electric telescopic rods 28 are fixedly connected inside the grooves 27, and one end of the electric telescopic rods 28 is fixedly connected to an inner clamping plate 29. First connecting rods 30 are fixedly connected to both sides of the material taking plate 25, and one end of the first connecting rod 30 is slidably connected to a second slide plate 31, and the side walls of the second slide plate 31 are fixedly connected to a second connecting plate 32. A semicircular plate 33 is fixedly connected between the opposite ends of the second connecting plate 32, and inner grooves 34 are provided on both sides of the semicircular plate 33. A clamping column 35 is slidably connected to the inside of the inner groove 34. The shape of the clamping column 35 The shape is L-shaped, and the outer wall of the clamping column 35 is sleeved with a telescopic spring 36. One end of the clamping column 35 is fixedly connected to a blanking clamping plate 37. One end of the telescopic spring 36 is fixedly connected to the inner wall of the inner groove 34, and the other end of the telescopic spring 36 is fixedly connected to the side wall of the blanking clamping plate 37. One end of the clamping column 35 passes through the outer wall of the inner groove 34. The top of the grinding table 3 is fixedly connected to the support frame 4 on the side away from the support plate 7. The two ends of the side of the fixed frame 38 close to the limit plate 6 are fixedly connected to the extrusion plate 39. The side wall of the extrusion plate 39 is in an arc shape. When the clamping column 35 is close to the side wall of the extrusion plate 39, it will contact the outer wall of the extrusion plate 39.

[0036] When the loading and unloading mechanism is in use, firstly, the conveyor belts 5 on both sides of the top of the grinding table 3 are started by an external driving source, and then the gear to be ground is placed on the top of the conveyor belt 5. When it is transmitted to the other side of the conveyor belt 5, the first motor 8 is started, and the first motor 8 drives the rotating column 9 to rotate. The rotating column 9 drives the first cam 12 and the second cam 18 on both sides of the outer wall to rotate synchronously. When the second cam 18 rotates, it will drive the up-and-down moving groove 19 to rotate. At this time, the second roller 22 slides in the up-and-down moving groove 19. The shape of the up-and-down moving groove 19 is rhombus-shaped. The shape opened by the up-and-down moving groove 19 will squeeze the extrusion rod 2 through the second roller 22. 1 rotates, and when the extrusion rod 21 rotates, it will drive the second roller 22 on the other side to move downward, and then the second roller 22 will slide in the slide groove 24 and push the upper and lower sliding plates 23 to slide downward on the side wall of the reciprocating plate 11. When the upper and lower sliding plates 23 slide downward, they will drive the inner circle block 26 to move to the middle of the gear through the material-collecting plate 25. When it moves to the middle of the gear, the electric telescopic rod 28 inside the groove 27 will drive the inner clamping plate 29 at one end to extend to both sides and clamp the inner wall of the gear. After clamping, when the second cam 18 drives the upper and lower moving grooves 19 to continue to rotate, it will drive the clamped gear to move upward through the inner circle block 26;

[0037] When the first cam 12 rotates, it drives the rotating groove 13 to rotate. When the rotating groove 13 rotates, it drives the first roller 15 to slide along the inside of the rotating groove 13 through its own shape. The shape of the rotating groove 13 is triangular. When the first roller 15 slides inside the rotating groove 13, it drives the reciprocating rod 14 to reciprocate left and right. Then the reciprocating rod 14 drives the moving column 17 at the other end to slide in the through groove 16. When the moving column 17 is pushed by the reciprocating rod 14, it drives the reciprocating plate 11 to slide between the first slide groove plate 10. The reciprocating plate 11 drives the upper and lower sliding plates 23 to the grinding table 3. When the upper and lower sliding plates 23 move in the direction of the upper and lower sliding plates 23, the inner circular block 26 holding the gear will move toward the top of the grinding table 3 through the feeding plate 25. When it moves to the top of the grinding table 3, the electric telescopic rod 28 drives the inner clamping plate 29 to retract into the groove 27. After the gear has no clamping force, it will be placed on the top of the grinding table 3. When the first cam 12 continues to rotate and the next material is loaded, the inner circular block 26 will be driven to return to the original path in the direction of the support plate 7 through the feeding plate 25. At the same time, the feeding plate 25 will also drive the first connecting rod 30 to move synchronously, and the first connecting rod 30 drives the second slide plate 31 and the second connecting rod 31. The plate 32 and the semicircular plate 33 move toward the support plate 7. When the semicircular plate 33 moves to the top of the grinding table 3, the gear can be squeezed by the limit plate 6. At this time, the gear will squeeze the unloading clamping plates 37 on both sides. The unloading clamping plates 37 will shrink back into the inner groove 34 and squeeze the telescopic spring 36. The unloading clamping plates 37 are squeezed by the spring force of the telescopic spring 36, thereby further fixing and limiting the gear. Then, the grinding machine body 1 is started to grind the gear. After grinding, when the material is loaded again through the loading and unloading mechanism, the picking plate 25 will push the first connecting rod 30 and the second slide groove The plate 31 and the second connecting plate 32 and the semicircular plate 33 move toward the fixing frame 38. When the semicircular plate 33 holding the gear moves to the bottom of the fixing frame 38, the clamping column 35 contacts the side wall of the extrusion plate 39 and squeezes the clamping column 35. The clamping column 35 is further squeezed by the force, which drives the unloading clamping plate 37 to further shrink into the inner groove 34. At this time, the unloading clamping plate 37 leaves the outer wall of the gear, releasing the limit on the gear, and the polished gear falls onto the conveyor belt 5 on the other side of the grinding table 3, and is transported to the next link through the conveyor belt 5, thereby completing the loading and unloading of the gear.

[0038] When the second cam 18 in the loading and unloading mechanism rotates, it will drive the upper and lower sliding plates 23 to slide downward on the side wall of the reciprocating plate 11, and then the upper and lower sliding plates 23 drive the inner circle block 26 to clamp the opposite gear through the material picking plate 25. After clamping, the second cam 18 continues to rotate to drive the face gear to move upward and leave the top of the conveyor belt 5, thereby realizing the motion trajectory of driving the inner circle block 26 to move up and down to achieve material picking, and then the first cam 12 rotates to drive the reciprocating rod 14 to rotate, and the reciprocating rod 14 drives The reciprocating plate 11 slides left and right between the first slide plate 10. When the reciprocating plate 11 slides, it will drive the inner circle block 26 holding the face gear to move to the top of the grinding table 3. When the first cam 12 continues to rotate, it will drive the material picking plate 25 and the inner circle block 26 to return to the original path to clamp the gear at the top of the conveyor belt 5. At the same time, it will also drive the semicircular plate 33 to squeeze and clamp the face gear. After clamping, the gear can be ground. After grinding, when the material is fed again through the inner circle block 26, it will drive the semicircular plate holding the gear. 33 is moved to the conveyor belt 5 on the other side, and the material can be unloaded by squeezing through the squeezing plate 39, thereby realizing a fully automated loading and unloading process, completely getting rid of manual intervention, and solving the problem that the face gears need to be placed one by one on the processing platform by the operator and manually removed after the processing is completed, which not only increases the work intensity of the operator, but also significantly reduces the overall production efficiency. At the same time, manual loading also leads to inaccurate positioning of the workpiece, thereby affecting the problem of processing accuracy. The operator only needs to place the gear to be processed on one end of the conveyor belt 5, and the equipment can transfer the gear to the top of the grinding table 3 through the loading and unloading mechanism. This automated operation not only greatly reduces the labor intensity of the operator, but also significantly improves production efficiency, especially in large-scale processing scenarios, the entire processing process can be completed with a stable and efficient beat, and it is manual loading, and it also avoids the manual placement of face gears that affects the processing accuracy, thereby achieving reliable limiting of the gear, ensuring the stability and consistency of the processing process.

[0039] For further information, see Attachment Fig.11 As shown, a water pump 40 is fixedly connected to the side wall of the water tank 2, and a water spray pipe 41 is fixedly connected to the side wall of the water pump 40. The water outlet end of the water spray pipe 41 is close to the top of the grinding table 3. During grinding, the water in the water tank 2 is pumped into the water spray pipe 41 through the water pump 40, and then sprayed onto the contact surface between the grinding sheet and the gear, thereby cooling the gear and the grinding sheet.

[0040] For further information, see Attachment Fig.11 and Fig.12As shown, the anti-clogging mechanism includes an inclined plate 42 fixedly connected to the four surfaces of the inner wall of the grinding table 3. The inclined plate 42 is arranged at an angle. The inclined plate 42 plays a role in guiding the water flowing in through the leakage hole to prevent the water from flowing out of the outside of the grinding table 3 through the sliding hole 44 along the inner wall of the grinding table 3. A filter screen 43 is fixedly connected to the top of the inner wall of the water tank 2. The interior of the grinding table 3 and the interior of the water tank 2 are connected to each other. Sliding holes 44 are provided on both sides of the grinding table 3. The bottom end of the second slide plate 31 passes through the sliding hole 44 and extends into the grinding table 3. A scraper plate 45 is fixedly connected between the bottom ends of the second slide plate 31. The bottom of the scraper plate 45 contacts the top of the filter screen 43. Storage tanks 46 are fixedly connected to both sides of the grinding table 3. The top of the storage tank 46 is connected to the interior of the grinding table 3. The water mixed with the impurities after grinding flows to the top of the grinding table 3, and then flows to the filter screen 43 through the leakage hole opened on the top of the grinding table 3 for filtration. The filtered water then flows into the water tank 2. When it is necessary to clean the debris on the top of the filter screen 43 to prevent clogging, the first connecting rod 30 and the second slide plate 31 are driven by the picking plate 25 in the loading and unloading mechanism to move and load the material, which will drive the scraper plate 45 fixed between the second slide plate 31 to slide on the top of the filter screen 43. When the scraper plate 45 slides, it will scrape the debris to the storage tank 46 for accumulation. When loading, the loading and unloading mechanism will drive the scraper plate 45 in the anti-clogging mechanism to scrape the debris on the top of the filter screen 43 to the storage tank 46 for centralized treatment, thereby avoiding the clogging of the filter screen 43 due to impurities or debris, resulting in poor water flow and reduced filtration efficiency, thereby ensuring smooth water flow.

[0041] For further information, see Attachment Figure 8 As shown, the outer walls of the inner circular block 26 and the inner clamping plate 29 are adapted to the interior of the gear, and the outer wall of the inner clamping plate 29 is provided with an anti-skid groove, which increases the friction between the inner clamping plate 29 and the inner wall of the gear.

[0042] For further information, see Attachment Fig. 9 As shown, a plurality of equally spaced and evenly distributed leakage holes are provided on the top of the grinding table 3, through which the water mixed with the grinding debris can be cooled and conveniently retained in the water tank 2 for recycling and reuse, thus saving the waste of water resources.

[0043] The present application also provides a face gear CNC machining method, using the above-mentioned face gear CNC machining device, comprising the following steps:

[0044] S1. Picking up materials: When the second cam 18 in the loading and unloading mechanism rotates, the upper and lower sliding plates 23 are driven to slide downward on the side wall of the reciprocating plate 11, and then the upper and lower sliding plates 23 drive the inner circle block 26 to clamp the surface gear through the material picking plate 25. After clamping, the second cam 18 continues to rotate to drive the surface gear to move upward and away from the top of the conveyor belt 5, thereby realizing the motion trajectory of driving the inner circle block 26 to move up and down to achieve material picking, avoiding manual intervention and reducing the labor intensity of workers.

[0045] S2. Loading: The first cam 12 rotates to drive the reciprocating rod 14 to rotate, and the reciprocating rod 14 drives the reciprocating plate 11 to slide left and right between the first slide slot plates 10. When the reciprocating plate 11 slides, it drives the inner circle block 26 holding the face gear to move to the top of the grinding table 3, thereby realizing loading. Automated loading saves time, especially in mass production, and can quickly and stably complete the loading of gears, thereby improving overall production efficiency.

[0046] S3. Clamping: When the first cam 12 continues to rotate, it will drive the material taking plate 25 and the inner circular block 26 to return to the original path to clamp the gear on the top of the conveyor belt 5, and at the same time, it will drive the semicircular plate 33 to squeeze and clamp the opposite gear. After clamping, the gear can be ground without manual loading, thereby ensuring the clamping and processing accuracy.

[0047] S4, grinding cooling: the water in the water tank 2 is pumped into the water spray pipe 41 through the water pump 40, and then sprayed onto the contact surface between the grinding and polishing disc and the gear, thereby cooling down, reducing the thermal damage of the grinding tool and the gear, extending the service life of the equipment, and ensuring the stability of production.

[0048] S5, unloading: After grinding, when the inner circle block 26 is used to load the material again, the semicircular plate 33 holding the gear will be driven to move to the conveyor belt 5 on the other side, and the material can be unloaded by squeezing through the squeezing plate 39, thus avoiding manual intervention and improving production efficiency.

[0049] S6.
