Description

Technical Field

[0001] The present invention belongs to the technical field of gear grinding, and specifically relates to a device for grinding and removing burrs at the edges and corners of gear processing. Background Art

[0002] A gear is a toothed wheel-shaped part on a machine, usually meshed in pairs, with one rotating and the other being driven. Its functions include changing the transmission direction, rotation direction, rotation speed, torque, etc. During the gear processing, burrs may exist at the edges and corners of the gear. These burrs may cause problems such as jamming and tooth skipping on the tooth surface, affecting the smooth operation of the gear. By grinding and polishing, these burrs can be removed, thereby ensuring smooth meshing of the gear during operation and improving its transmission efficiency.

[0003] The patent with the publication number CN221583005U discloses a grinding device for deburring gears, including: a housing provided with a processing position, in which a gear body and a rotating mechanism are sequentially installed from top to bottom. A movable grinding mechanism is installed on one side of the gear body. The grinding mechanism has two grinding parts arranged up and down and a moving mechanism for driving the two grinding parts to approach the gear body. A grinding area is formed between the two grinding parts for grinding the upper and lower surfaces at the edge position of the gear body. Through the added moving mechanism and grinding parts, the moving mechanism can drive the two grinding parts to approach the gear body, and the two grinding parts are respectively located on the upper and lower sides of the gear body. When the gear body rotates, the two grinding parts can simultaneously grind and remove burrs on both sides of the gear body.

[0004] However, the above technical solution still has the following deficiencies in actual application:

[0005] By driving the gear body and the grinding block to rotate and rub against each other to achieve the grinding and removal of burrs on the gear surface. However, since there is usually one or more assembly holes in the middle of the gear, and during the grinding process, flying debris will be generated. Therefore, these debris may fly and adhere to the inner wall of the assembly hole, resulting in errors during the gear assembly process, affecting the assembly accuracy of the gear, and even the situation where the assembly hole is blocked by debris and the gear cannot be normally installed. Moreover, it is rather troublesome to clean the assembly hole to avoid the above situation, especially for some large gears. The large gears have a large volume and a higher cleaning difficulty.

[0022] 2. In a deburring and removing device for gear processing according to the present invention, by using an assembly hole covering mechanism, during the entire grinding and polishing process, the gear assembly hole is covered by an adjusting cloth. Therefore, the splashing debris will be blocked by the adjusting cloth and will not splash into the gear assembly hole, thus ensuring the cleanliness of the hole wall of the gear assembly hole, avoiding the situation where debris splashes and adheres to the inner wall of the assembly hole, resulting in errors during the gear assembly process, affecting the assembly accuracy of the gear, and even causing the assembly hole to be blocked by debris and the gear unable to be normally installed. It saves the process of cleaning the assembly hole again after the grinding work is completed, which is relatively labor-saving. Moreover, since the area of the encirclement formed by multiple adjusting cloths is adjustable, the encirclement formed by the adjusting cloth will only cover the assembly hole area and will not affect the grinding of the upper end face of the gear. Additionally, by using an adjustable filling mechanism, when grinding the upper surface of each tooth, the corresponding tooth grooves on both sides of the tooth can be covered by a soft pad, thus avoiding the situation where when only grinding the upper and lower surfaces of the tooth, debris splashes and adheres to the tooth grooves, affecting the subsequent transmission effect of the gear. Similarly, it also saves the process of cleaning the debris at the tooth grooves, which is relatively convenient and labor-saving. Furthermore, whenever the soft pad covers the tooth groove, two adjacent reinforcing rollers can be driven to rotate in different directions simultaneously, pressing the soft pad tightly against the inner side of the tooth groove, thereby further ensuring the degree of fitting between the soft pad and the inner side of the tooth groove, and avoiding the situation where during the grinding process, due to the vibration of the entire device, the soft pad does not fit tightly enough with the tooth groove, and debris still adheres to the tooth groove.

[0045] The adjustable filling mechanism includes a fixing plate 8 fixedly connected to one side of the upper end surface of the workbench 1. A second groove plate 11 is fixedly connected to the upper end of the fixing plate 8. Two sliders 14 are slidably connected to both sides of the chute of the second groove plate 11.

One end of the rotating arm 22 is fixedly connected with a reinforcing roller 23. One end of the rotating arm 22 is fixedly connected with a second gear 21. Adjacent second gears 21 mesh with each other. One side of the upper end of the pushing plate 18 is fixedly connected with a third motor 20. The output end of the third motor 20 is fixedly connected with one end of the rotating arm 22.

[0049] Specifically, in the prior art, the burrs on the surface of the gear are removed by driving the rotation and friction of the gear body and the grinding block. However, since one or more assembly holes are usually provided in the middle of the gear, and during the grinding process, flying debris will be generated. Therefore, these debris may fly and adhere to the inner wall of the assembly hole, resulting in errors during the gear assembly process, affecting the assembly accuracy of the gear, and even causing the assembly hole to be blocked by debris and the gear cannot be normally installed. Moreover, it is rather troublesome to clean the assembly hole to avoid the above situation. Especially for some large gears, the large gears have a large volume and the cleaning difficulty is even higher.

[0050] Therefore, in order to solve the above problems, when the present embodiment is in use, after the gear to be polished is fixed, according to the distribution area of ​​the gear assembly hole, the motor 4 24 is used to drive the threaded rod 26 to rotate, so that the multiple connecting rods 1 28 rotate at the same time, and the multiple adjusting rods 43 move radially at the same time. Since the adjusting cloth 6 is elastic, the adjusting cloth 6 will deform with the movement of the adjusting rod 43 until the encirclement formed by the multiple adjusting cloths 6 can cover the gear assembly hole, and then the motor 1 3 is used to drive the threaded rod 1 4 to rotate, so that the connecting plate 5 descends until the bottom of the adjusting cloth 6 is in contact with the upper surface of the gear. At this time, the position of the polishing disk 34 can be adjusted by driving the threaded rod 30 to rotate by the motor 5 29 and driving the electric push rod 2 32 to lift the adjusting block 42, so that the polishing disk 34 is in contact with the surface of the area outside the gear assembly hole, and then the motor 6 35 is used to drive the polishing The optical disc 34 rotates to grind the corners of the gear surface. At the same time, the motor 8 40 can be used to drive the rotating rod 10 to rotate, so that the gear being grinded rotates to achieve uniform grinding. During the entire grinding process, the gear assembly hole is covered by the adjusting cloth 6, so the flying debris will be blocked by the adjusting cloth 6 and will not splash into the gear assembly hole, thereby ensuring the cleanliness of the hole wall of the gear assembly hole, avoiding the debris from splashing and adhering to the inner wall of the assembly hole, causing errors in the gear assembly process, affecting the assembly accuracy of the gear, and even causing the assembly hole to be blocked by debris, so that the gear cannot be installed normally. The process of cleaning the assembly hole after the grinding work is completed is omitted, which is more labor-saving. In addition, since the area of ​​the encirclement formed by the multiple adjusting cloths 6 is adjustable, the encirclement formed by the adjusting cloths 6 will only cover the assembly hole area without affecting the grinding of the upper end face of the gear.

[0051] Although the above method can prevent the debris generated during the grinding and polishing process from splashing onto the inner wall of the gear assembly hole, in some cases, the burrs at the edges and corners of the gear are only concentrated on the upper and lower surfaces of the teeth. At this time, only the upper and lower surfaces of the teeth need to be ground. Although the assembly hole can be covered by adjusting the cloth 6, the debris will still splash and adhere to the tooth grooves of the gear. When the debris accumulates in the tooth grooves of the gear, it will also affect the transmission effect during the subsequent use of the gear. Moreover, the shape of the tooth grooves is relatively complex, and it is difficult to clean them thoroughly later. Therefore, to avoid this situation, when only the upper and lower surfaces of the gear teeth need to be ground, the tray 9 is driven to drive the gear to rotate, so that each tooth of the gear moves to the polishing disc 34 in turn, and the polishing disc 34 is used for grinding. Before grinding, according to the size of the teeth and the spacing between the teeth, the second motor 13 drives the first gear 12 to rotate, so that the slider 14 slides on the second groove plate 11, and the positions of the two soft pads 19 can be adjusted, so that the two soft pads 19 are both aligned with the middle parts of the tooth grooves on both sides of the teeth. Then, the first electric push rod 16 drives the soft pad 19 to move into the tooth groove. Since the soft pad 19 is elastic, the soft pad 19 will fill and cover the tooth groove. After the covering is completed, the burrs on the upper surface of the tooth can be ground and removed. During the grinding and removing process, the splashed debris usually splashes to the tooth grooves on both adjacent sides of the tooth. Therefore, even if the debris splashes to the tooth groove, it will adhere to the surface of the soft pad 19 and will not directly contact the inner side of the tooth groove of the gear. Then, repeat the above operation. When grinding the upper surface of each tooth, the corresponding tooth grooves on both sides of the tooth can be covered by the soft pad 19, thus avoiding the situation that when only the upper and lower surfaces of the teeth need to be ground, the debris splashes and adheres to the tooth grooves, affecting the subsequent transmission effect of the gear. Similarly, the process of cleaning the debris in the tooth grooves is also omitted, which is more convenient and labor-saving;

[0052] After one side of the gear is ground, turn the gear over and repeat the above operation to achieve the grinding of the other side of the gear;

[0053] Although the soft pad 19 can be used to prevent the debris from splashing into the tooth grooves, since the soft pad 19 is elastic, during the grinding process, the whole device will inevitably vibrate, which may cause the soft pad 19 to not fit tightly with the tooth grooves due to vibration, and the debris still adheres to the tooth grooves. Therefore, to solve this problem, whenever the soft pad 19 covers the tooth groove, the third motor 20 can be used to drive the rotating arm 22 on one side to rotate, and under the action of the two second gears 21, the adjacent two reinforcing rollers 23 rotate simultaneously and in different directions, pressing the soft pad 19 tightly against the inner side of the tooth groove, thus further ensuring the degree of fit between the soft pad 19 and the inner side of the tooth groove, and avoiding the situation that during the grinding process, due to the vibration of the whole device, the soft pad 19 does not fit tightly with the tooth grooves, and the debris still adheres to the tooth grooves.

[0054] Working principle: The gear to be polished is placed on the tray 9, and multiple positioning plates 36 pass through the assembly hole in the center of the gear. Then, the motor 7 37 is used to drive the turntable 38 to rotate, so that multiple connecting rods 2 39 can be rotated at the same time, and multiple positioning plates 36 can be driven to slide radially on the tray 9 at the same time, until multiple positioning plates 36 are in contact with the wall of the gear assembly hole, so that the gear can be fixed, thereby ensuring the stability of the gear during the polishing process, not easy to deviate, which is conducive to improving the polishing efficiency. When the gear to be polished is fixed, the gear assembly hole is divided into the gear assembly hole and the gear assembly hole is rotated. The area of ​​the cloth is increased, and the motor 4 24 is used to drive the threaded rod 26 to rotate, so that the multiple connecting rods 1 28 rotate at the same time, and the multiple adjusting rods 43 move radially at the same time. Since the adjusting cloth 6 has elasticity, the adjusting cloth 6 will deform with the movement of the adjusting rod 43 until the encirclement formed by the multiple adjusting cloths 6 can cover the gear assembly hole, and then the motor 1 3 is used to drive the threaded rod 1 4 to rotate, so that the connecting plate 5 descends until the bottom of the adjusting cloth 6 fits with the upper surface of the gear. At this time, the motor 5 29 can drive the threaded rod 3 30 to rotate , the electric push rod 2 32 drives the adjustment block 42 to rise and fall to adjust the position of the polishing disc 34, so that the polishing disc 34 is fitted with the surface of the area outside the gear assembly hole, and then the motor 6 35 is used to drive the polishing disc 34 to rotate, so that the corners of the gear surface can be polished. At the same time, the motor 8 40 can be used to drive the rotating rod 10 to rotate, so that the gear being polished rotates to achieve uniform polishing. During the entire polishing process, the gear assembly hole is covered by the adjustment cloth 6, so the flying debris will be blocked by the adjustment cloth 6 and will not splash into the gear assembly hole, thereby ensuring the cleanliness of the gear assembly hole wall, avoiding the debris from splashing and adhering to the inner wall of the assembly hole, resulting in errors in the gear assembly process, affecting the assembly accuracy of the gear, and even causing the assembly hole to be blocked by debris, so that the gear cannot be installed normally, eliminating the process of cleaning the assembly hole after the polishing work is completed, which is more labor-saving. In addition, since the area of ​​the encirclement formed by the multiple adjustment cloths 6 is adjustable, the encirclement formed by the adjustment cloths 6 will only cover the assembly hole area without affecting the polishing of the upper end face of the gear;Although through the above method, it is possible to prevent the debris generated during the grinding process from splashing onto the hole wall of the gear assembly hole. However, in some cases, the burrs at the edges and corners of the gear are only concentrated on the upper and lower surfaces of the teeth. At this time, only the upper and lower surfaces of the teeth need to be ground. Although the adjusting cloth 6 can be used to cover the assembly hole, the debris will still splash and adhere to the tooth grooves of the gear. When the debris accumulates in the tooth grooves of the gear, it will also affect the transmission effect during the subsequent use of the gear. Moreover, the shape of the tooth grooves is relatively complex, and it is difficult to clean up later, making it difficult to ensure complete removal. Therefore, to avoid this situation, when only the upper and lower surfaces of the teeth of the gear need to be ground, by driving the tray 9 to drive the gear to rotate, each tooth of the gear is sequentially moved to the polishing disc 34, and the polishing disc 34 is used for grinding. And before grinding, according to the size of the teeth and the spacing between the teeth, the second motor 13 drives the first gear 12 to rotate, so that the slider 14 slides on the second groove plate 11, and the positions of the two soft pads 19 can be adjusted, so that the two soft pads 19 are both aligned with the middle parts of the tooth grooves on both sides of the teeth. Then, the first electric push rod 16 drives the soft pad 19 to move into the tooth groove. Since the soft pad 19 has elasticity, the soft pad 19 will fill and cover the tooth groove. After the covering is completed, the burrs on the upper surface of the teeth can be ground and removed. During the grinding and removal process, the splashed debris usually splashes to the tooth grooves on both adjacent sides of the teeth. Therefore, even if the debris splashes to the tooth grooves, it will adhere to the surface of the soft pad 19 and will not directly contact the inner side of the tooth grooves of the gear. Then, repeat the above operation. When grinding the upper surface of each tooth, the corresponding tooth grooves on both sides of the tooth can be covered by the soft pad 19, thus avoiding the situation where debris splashes and adheres to the tooth grooves when only the upper and lower surfaces of the teeth need to be ground, which affects the subsequent transmission effect of the gear. Similarly, the process of cleaning the debris in the tooth grooves is also omitted, which is more convenient and labor-saving. When one side of the gear is ground, the gear is flipped, and the above operation is repeated to achieve the grinding of the other side of the gear. Although the soft pad 19 can be used to prevent debris from splashing into the tooth grooves, because the soft pad 19 has elasticity, during the grinding process, the entire device will inevitably vibrate, which may cause the soft pad 19 to not fit tightly with the tooth grooves due to vibration, and there will still be a situation where debris adheres to the tooth grooves. Therefore, to solve this problem, whenever the soft pad 19 covers the tooth groove, the third motor 20 can be used to drive the rotating arm 22 on one side to rotate, and under the action of the two second gears 21, the adjacent two reinforcing rollers 23 rotate simultaneously in different directions, pressing the soft pad 19 tightly against the inner side of the tooth groove, thereby further ensuring the degree of fit between the soft pad 19 and the inner side of the tooth groove, and avoiding the situation where the soft pad 19 does not fit tightly with the tooth grooves due to the vibration of the entire device during the grinding process, and there is still debris adhering to the tooth grooves.;
