Description

Technical Field

[0001] The invention belongs to the technical field of gear grinding, in particular to a device for grinding and removing burrs at corners used in gear processing. Background Art

[0002] Gears are wheel-shaped parts with teeth on machines, usually meshing in pairs, with one rotating and the other being driven. Their function is to change the transmission direction, rotation direction, rotation speed, torque, etc. During the processing of gears, burrs may appear on their edges and corners. These burrs may cause problems such as tooth jamming and tooth skipping, affecting the smooth operation of the gears. These burrs can be removed by grinding and polishing, thereby ensuring that the gears are smoothly engaged and unobstructed, thereby improving their transmission efficiency.

[0003] The patent with announcement number CN221583005U discloses a gear deburring grinding device, comprising: a shell provided with a processing position, in which a gear body and a rotating mechanism are installed in sequence from top to bottom, a movable grinding mechanism is installed on one side of the gear body, the grinding mechanism has two grinding pieces of two upper and lower parts and a moving mechanism for driving the two grinding pieces to approach the gear body, and a grinding area for grinding the upper and lower surfaces at the edge of the gear body is formed between the two grinding pieces. This patent uses an additional moving mechanism and grinding pieces, and the two grinding pieces can be driven to approach the gear body through the moving mechanism, and the two grinding pieces are respectively located on the upper and lower sides of the gear body. When the gear body rotates, the two grinding pieces can simultaneously perform double-sided grinding and deburring on the gear body.

[0004] However, the above technical solution still has the following deficiencies in practical application: The burrs on the gear surface are removed by driving the gear body and the grinding block to rotate and rub. However, since a single or multiple assembly holes are usually provided in the middle of the gear, flying debris will be generated during the grinding process. Therefore, these debris may fly and adhere to the inner wall of the assembly hole, thereby 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, making it impossible to install the gear normally. In addition, it is also troublesome to clean the assembly hole to avoid the above situation, especially for some large gears, which are larger in size and more difficult to clean.

[0029] The workbench 1 is also provided with an adjustable filling mechanism to prevent debris from splashing onto the tooth grooves; The adjustable filling mechanism includes a fixed plate 8 fixedly connected to one side of the upper end surface of the workbench 1, a groove plate 11 is fixedly connected to the upper end of the fixed plate 8, both sides of the groove of the groove plate 11 are slidably connected with sliders 14, a mounting plate 15 is fixedly connected to one side of the upper end of the slider 14, two sliding rods 17 are slidably connected to the mounting plate 15, one end of the sliding rod 17 is fixedly connected to a push plate 18, and one side of the push plate 18 is fixedly connected to a soft pad 19.

[0030] A gear 12 is rotatably provided on one side of the slider 14, and a plurality of tooth blocks are provided on one side of the slot plate 11.

A motor 3 20 is fixedly connected to one side of the upper end of the push plate 18, and the output end of the motor 3 20 is fixedly connected to one end of the rotating arm 22.

[0033] Specifically, in the prior art, the burrs on the gear surface are removed by driving the gear body and the grinding block to rotate and rub. However, since a single or multiple assembly holes are usually provided in the middle of the gear, and flying debris is generated during the grinding process, the debris may fly and adhere to the inner wall of the assembly hole, thereby 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. In addition, it is also troublesome to clean the assembly hole to avoid the above situation, especially for some large gears, which are larger in size and more difficult to clean. 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. Although the above method can prevent the debris generated during the grinding and polishing process from splashing into the hole wall of the gear assembly hole, in some cases, the burrs on the 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 polished. Although the assembly hole can be covered with the adjusting cloth 6, the debris will still splash and adhere to the tooth groove of the gear. When the debris accumulates in the tooth groove of the gear, it will also affect the transmission effect of the gear during subsequent use. In addition, the shape of the tooth groove is relatively complex, and it is also difficult to clean it up later, and it is difficult to ensure complete removal. Therefore, in order to avoid this situation, when only the upper and lower surfaces of the gear teeth need to be polished, the tray 9 is driven to drive the gear to rotate, so that each tooth on the gear is moved to the polishing disk 34 in turn, and the polishing disk 34 is used for polishing. Moreover, before polishing, according to the size of the teeth and the spacing between the teeth, the motor 2 13 is used to drive the gear 1 12 to rotate, so that the slider 1 By sliding at the groove plate 2 11, the positions of the two soft pads 19 can be adjusted so that the two soft pads 19 are aligned with the middle of the tooth grooves on both sides of the tooth, and then the electric push rod 1 16 is used to drive 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 covering, the burrs on the upper surface of the tooth can be polished and removed. During the polishing and removal process, the flying debris usually splashes to the tooth grooves on both 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 polishing each pair of tooth upper surfaces, the soft pad 19 can be used to cover the tooth grooves corresponding to both sides of the tooth, thereby avoiding the situation that when only the upper and lower surfaces of the tooth need to be polished, the debris splashes and adheres to the tooth groove, affecting the subsequent transmission effect of the gear. Similarly, the process of cleaning the debris at the tooth groove is omitted, which is more convenient and labor-saving. When one side of the gear is polished, turn the gear over and repeat the above steps to polish the other side of the gear. Although the soft pad 19 can be used to prevent debris from splashing into the tooth groove, the soft pad 19 is elastic, so the entire device will inevitably vibrate during the grinding process, which may cause the soft pad 19 to not fit tightly enough with the tooth groove due to vibration, and debris will still adhere to the tooth groove. Therefore, in order to solve this problem, every time the soft pad 19 covers the tooth groove, the motor three 20 can be used to drive the rotating arm 22 on one side to rotate, and under the action of the two gears two 21, the two adjacent reinforcement rollers 23 are rotated in different directions at the same time, pressing the soft pad 19 against the inner side of the tooth groove, thereby further ensuring the fit between the soft pad 19 and the inner side of the tooth groove, and avoiding the situation in which the soft pad 19 and the tooth groove are not fit tightly enough due to the vibration of the entire device during the grinding process, and debris will still adhere to the tooth groove.

[0034] 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 the above method can prevent the debris generated during the grinding process from splashing into the hole wall of the gear assembly hole, in some cases, the burrs on the 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 polished. Although the assembly hole can be covered with the adjusting cloth 6, the debris will still splash and adhere to the tooth groove of the gear. When the debris accumulates in the tooth groove of the gear, it will also affect the transmission effect of the gear during subsequent use. In addition, the shape of the tooth groove is relatively complex, and it is difficult to clean it up later, and it is difficult to ensure complete removal. Therefore, in order to avoid this situation, when only the upper and lower surfaces of the gear teeth need to be polished, the tray 9 is driven to drive the gear to rotate. In this way, each tooth on the gear is moved to the polishing disc 34 in turn and polished by the polishing disc 34. Before polishing, according to the size of the tooth and the spacing between the teeth, the motor 2 13 is used to drive the gear 12 to rotate, so that the slider 14 slides on the groove plate 2 11, and the positions of the two soft pads 19 can be adjusted so that the two soft pads 19 are aligned with the middle of the tooth grooves on both sides of the tooth. Then, the electric push rod 16 is used to drive 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 covering, the burrs on the upper surface of the tooth can be polished and removed. During the polishing and removal process, the splashed debris usually splashes to the tooth grooves on both 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 each pair of upper surfaces of a tooth, the soft pad 19 can be used to cover the tooth grooves corresponding to both sides of the tooth, thereby avoiding the situation where the debris splashes and adheres to the tooth groove when only the upper and lower surfaces of the tooth need to be ground, affecting the subsequent transmission effect of the gear. Similarly, it also saves the process of cleaning the debris at the tooth groove, which is more convenient and labor-saving. When one side of the gear is polished, turn the gear over and repeat the above operation to achieve the grinding of the other side of the gear. Although the soft pad 19 can be used to prevent the debris from splashing into the tooth groove, due to the soft pad 19 has Therefore, during the grinding process, the entire device will inevitably vibrate, which may cause the soft pad 19 to not fit tightly with the tooth groove due to vibration, and debris will still adhere to the tooth groove. Therefore, in order to solve this problem, every time the soft pad 19 covers the tooth groove, the motor 3 20 can be used to drive the rotating arm 22 on one side to rotate, and under the action of the two gears 21, the two adjacent reinforcement rollers 23 are rotated in different directions at the same time to press the soft pad 19 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, avoiding the situation that the soft pad 19 and the tooth groove are not fit tightly enough due to the vibration of the entire device during the grinding process, and debris will still adhere to the tooth groove. ;
