Description

Technical Field

[0001] This invention belongs to the field of gear technology, and more specifically, relates to a gear deburring device. Background Technology

[0002] In the field of mechanical manufacturing, gears are key components for transmitting motion and power, and their machining accuracy directly affects the operational stability, transmission efficiency, and service life of the entire mechanical system. During gear hobbing, shaping, and shaving processes, burrs inevitably form on the tooth surfaces and roots. If these burrs are not removed promptly, they will not only cause additional friction, vibration, and noise during gear meshing, but may also lead to accelerated gear wear due to burr shedding during long-term operation, and even cause equipment failure. Therefore, the deburring process is a crucial step in ensuring gear machining quality. Currently, there are many types of deburring devices for gears. Common types use grinding wheels, wire wheels, or abrasive stones as grinding tools, which remove burrs through the relative movement of the grinding tool and the gear tooth surface. However, most existing deburring devices can only work on one side of the gear tooth surface. When deburring both the upper and lower tooth surfaces of a gear is required, the operator must first polish and deburr one side of the gear tooth surface, then stop the machine, remove the gear from the device, rotate it at a certain angle, reinstall and fix it, and then start the device again to process the other side of the tooth surface. This operating method has obvious shortcomings: on the one hand, the repeated shutdowns, unloading, flipping, and reinstallation processes not only increase the operator's workload and prolong the deburring cycle of a single gear, but also reduce production efficiency; on the other hand, during the gear flipping and reinstallation process, it is difficult to ensure that the gear's positioning accuracy is completely consistent with that of the initial installation, which may lead to differences in the deburring effect on the upper and lower tooth surfaces, affecting the consistency of gear processing quality; in addition, frequent manual intervention also increases the uncertainty in the operation process, and is prone to gear damage or equipment failure due to operational errors, which is not conducive to achieving the requirements of automated and continuous production. Therefore, how to design a device that can simultaneously deburr both the upper and lower tooth surfaces of a gear, or that can sequentially process both tooth surfaces without manual flipping, in order to simplify the operation process, improve production efficiency, and ensure consistent processing quality, has become an urgent technical problem to be solved in the current research and development of gear deburring equipment.

[0023] The present invention aims to introduce and explain the structural composition of a gear deburring device and the matching relationship between the various components. Unless otherwise specified, the dimensions, materials and manufacturing processes of the various components in the gear deburring device of the present invention can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0024] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0025] Please refer to the following: Figures 1-5 This embodiment provides a gear deburring device, including a frame 1, a drive motor 11, a lower fixing mechanism 2, a first cylinder 12, an upper fixing mechanism 3, and a gear surface polishing mechanism 4; The drive motor 11 is mounted on the frame 1, and the lower fixing mechanism 2 is mounted on the output shaft of the motor. The lower fixing mechanism 2 can fix the gear from the inner ring of the gear. It should be understood that the gear is placed on the lower fixing mechanism 2 and fixed by the lower fixing mechanism 2. In this application, the lower fixing mechanism 2 uses a clamping method to fix the gear.

[0026] The first cylinder 12 is mounted on the frame 1, and the upper fixing mechanism 3 is mounted on the output shaft of the first cylinder 12. The descent of the upper fixing mechanism 3 can release the lower fixing structure from fixing the gear, and re-fix the gear from the inner ring of the gear, while maintaining the fixation and lifting the gear. It is worth mentioning that after the upper fixing mechanism 3 releases the lower fixing mechanism 2 from fixing the gear, the gear is still restricted within a certain range and will not be thrown out. After the upper fixing mechanism 3 fixes the gear from the top, it can maintain this fixed state when rising. Specifically, neither the lower fixing mechanism 2 nor the upper fixing mechanism 3 passes through the inner ring of the gear.

[0027] The tooth surface polishing mechanism 4 is telescopically mounted on the frame 1 and can polish and deburr the upper and lower tooth surfaces of the gear. Specifically, when the gear is placed on the lower fixed mechanism 2, the tooth surface polishing mechanism 4 can polish and deburr the upper tooth surface of the gear by telescopic movement. After the gear is lifted by the upper fixed mechanism 3, the tooth surface polishing mechanism 4 can polish and deburr the lower tooth surface of the gear by telescopic movement. When the drive motor 11 drives the lower fixed mechanism 2 to rotate, it drives the gear to rotate. Thus, the tooth profile polishing mechanism 5 can polish and deburr the tooth profile of the gear by its own rotation. After the gear is lifted, there is no need to polish the tooth profile of the gear.

[0028] In this application, when the gear is placed on the lower fixing mechanism 2, the tooth profile polishing mechanism 5 can polish and deburr the tooth profile of the gear, and the tooth surface polishing mechanism 4 can polish and deburr the upper tooth surface of the gear. After the tooth profile and upper tooth surface of the upper gear are polished and deburred, the upper fixing mechanism 3 is lowered to release the lower fixing mechanism 2 from fixing the gear. The upper fixing mechanism 3 then fixes the gear again and lifts it up. At this time, the lower tooth surface of the gear can be polished and deburred, thus completing the deburring operation of the tooth profile and upper and lower tooth surfaces of the gear without the operator having to manually disassemble and flip the gear.

[0029] In other embodiments, the lower fixing mechanism 2 includes a lower fixing seat 21, a lower fixing component 22, a fixing column 23, a pushing component 24, and a driven component 25. The lower fixing seat 21 is coaxially fixed on the output shaft of the drive motor 11. Multiple lower fixing components 22 are provided and slidably connected within the lower fixing seat 21. The fixing column 23 is fixed on the lower fixing seat 21. The pushing component 24 is slidably connected to the fixing column 23 and corresponds one-to-one with the lower fixing component 22. The driven component 25 is sleeved on the fixing column 23. The lifting and lowering of the driven component 25 can drive the sliding of each lower fixing component 22 through the pushing component 24. The lifting and lowering of the upper fixing mechanism 3 can drive the lifting and lowering of the driven component 25. Specifically, the lower fixing seat 21 is a tubular object with a closed bottom. The gear is placed on the top of the lower fixing seat 21, and the gear is clamped and fixed from the inside of the gear through the sliding of each lower fixing component 22.

[0030] In other embodiments, the lower fixing assembly 22 includes a lower fixing rod 221, a lower fixing pad 222, and a lower elastic rope 223. The lower fixing rod 221 is slidably connected to the lower fixing seat 21, and the lower fixing pad 222 is disposed on the lower fixing rod 221. Each lower fixing rod 221 is connected in pairs by the lower elastic rope 223, and the pushing assembly 24 can simultaneously slide the corresponding lower fixing rod 221. It should be understood that the lower fixing pad 222 is a flexible pad, which can increase the friction with the inner side of the gear, protect the inner side of the gear, and facilitate the direct removal of the gear. The lower fixing seat 21 is provided with a sliding groove, and the lower fixing rod 221 is slidably connected to the sliding groove. After the lower fixing rod 221 slides towards the inner side of the gear, the lower elastic rope 223 is in a stretched state.

[0031] In other embodiments, the driving component 24 includes an upper connecting plate 241, a lower connecting plate 242, and a sliding block 243. One end of the upper connecting plate 241 is hinged to the fixed post 23, and the other end of the upper connecting plate 241 is hinged to the lower connecting plate 242. The other end of the lower connecting plate 242 is hinged to the sliding block 243. The sliding block 243 is slidably connected to the fixed post 23, and the lifting or lowering of the driven component 25 can drive the lifting or lowering of the sliding block 243. Specifically, the lifting of the sliding block 243 causes the hinge between the upper connecting plate 241 and the lower connecting plate 242 to move downward to the fixed rod 221, and pushes the lower fixed rod 221 to move. As the sliding block 243 is lifted, the included angle between the upper connecting plate 241 and the lower connecting plate 242 gradually decreases.

[0032] In other embodiments, the driven component 25 includes a connecting ring 251 and a driven rod 252; the connecting ring 251 is sleeved on the fixed post 23, and the driven rod 252 is fixed on the connecting ring 251 and can be vertically inserted into the lower fixed seat 21. Specifically, the lower fixed post 23 is provided with an elongated through hole corresponding to the driven rod 252, and the driven rod 252 passes through the through hole. The lifting and lowering of the upper fixed mechanism 3 can drive the lifting and lowering of the driven rod 252. Preferably, there are multiple driven rods 252.

[0033] In other embodiments, the upper fixing mechanism 3 includes a fixing plate 31, a fixing disk 32, a one-way component 33, an upper fixing component 34, a fixing rack 35, a transmission component 36, a connecting rod 37, and a push ring 38; one side of the fixing plate 31 is connected to the telescopic end of the first cylinder 12, and the other end of the fixing plate 31 is fixedly provided with the fixing disk 32; the one-way component 33 is rotatably mounted on the fixing disk 32, and multiple sets of upper fixing components 34 are provided and slidably connected to the fixing disk 32. The rotation of the one-way component 33 can drive each upper fixing component 34 to reciprocate to approach and move away from each other; that is, each upper fixing component 34 periodically approaches and moves away from each other. A fixed rack 35 is fixed to the frame 1, and a transmission assembly 36 is rotatably mounted on the frame 1. The lifting and lowering of the fixed disk 32 can drive the transmission assembly 36 to rotate via the fixed rack 35, and the lowering of the fixed disk 32 can drive the one-way assembly 33 to rotate unidirectionally via the transmission mechanism. Specifically, the lowering of the fixed disk 32 drives the transmission assembly 36 to rotate forward, and the lifting of the fixed disk 32 drives the transmission assembly 36 to rotate in reverse. When the transmission assembly 36 rotates forward, it drives the one-way assembly 33 to rotate and moves the upper fixed assembly 34. When the transmission assembly 36 rotates in reverse, the one-way assembly 33 cannot drive the fixed assembly to move. One end of the connecting rod 37 is connected to the fixed disk 32, and the other end is connected to the push ring 38. The lifting and lowering of the push ring 38 can drive the lower fixed mechanism 2 to fix or release the gear. Specifically, the push plate is an annular plate and is sleeved on the lower fixed seat 21. The push plate is raised, which drives the driven rod 252 to rise, thereby reducing the included angle between the upper connecting plate and the lower connecting plate. The hinge of the upper connecting plate and the lower connecting plate pushes the lower fixed rod 221 to slide.

[0034] In other embodiments, the one-way mechanism includes a bevel gear ring 331, a turntable 332, a pawl 333, a spring 334, a rotating rod 335, and a pusher block 336; the bevel gear ring 331 is rotatably connected to the fixed disk 32, and a plurality of ratchet teeth are arranged around the inner side of the bevel gear ring 331; the turntable 332 is rotatably connected to the fixed disk 32 and coaxially disposed within the bevel gear ring 331; the pawl 333 is eccentrically rotatably connected to the turntable 332 and is connected to the turntable via the spring 334. Connected to 332, the bevel ring 331 can drive the turntable 332 to rotate unidirectionally via the pawl 333. Specifically, the forward rotation of the bevel ring 331 causes the pawl 333 and the turntable 332 to rotate together through its ratchet teeth engaging the pawl 333. The reverse rotation of the bevel ring 331 causes the pawl 333 to rotate repeatedly without driving the turntable 332 to rotate. The forward rotation of the transmission component 36 drives the bevel ring 331 to rotate forward, and the reverse rotation of the transmission component 36 drives the bevel ring 331 to rotate in reverse. The rotating rod 335 is coaxially fixed on the turntable 332 and passes through the fixed plate 32. The push block 336 is fixed at the end of the rotating rod 335 away from the turntable 332. The rotation of the push block 336 can periodically drive the upper fixed component 34 to move back and forth. Specifically, the push block 336 is an elliptical block, the center of which coincides with the axis of the rotating rod 335, and can also be approximated as a combination of multiple cams.

[0035] In other embodiments, the upper fixing assembly 34 includes an upper fixing rod 341, an upper fixing pad 342, and an upper elastic rope 343. Multiple upper fixing rods 341 are slidably connected to the fixing disk 32, and are connected by elastic ropes. The upper fixing pad 342 is fixed to the upper fixing rod 341, and the rotation of the pushing block 336 can move the upper fixing rod 341 to both sides. Specifically, two upper fixing rods 341 are provided opposite each other. The bottom surface of the fixing disk 32 has a straight groove corresponding to the upper fixing rod 341, and the central axis of the groove intersects with the center of the pushing block 336. The upper fixing pad 342 is a flexible pad. By increasing the friction on the inner side of the large gear, the gear can be lifted more effectively. Furthermore, because the upper fixing pad 342 is flexible, the gear can be smoothly removed directly after polishing. In use, after the upper and lower tooth surfaces of a gear are polished, the operator can directly remove the gear because the upper fixing pad 342 and the lower fixing pad 222 are flexible pads, and a new gear can be inserted into the lower fixing seat 21. It is also worth mentioning that the lengths of the upper fixing rod 341, upper fixing pad 342, lower fixing rod 221, and lower fixing pad 222 are all less than the thickness of the polished gear, ensuring that they do not pass through the gear when clamping and fixing it, thus avoiding interference with the tooth surface polishing mechanism 4. Simultaneously, when polishing the tooth surface, burrs can be removed from the top or bottom edge of the gear's inner ring through the polishing area.

[0036] In other embodiments, the transmission assembly 36 includes a transmission fixed base 361, a transmission shaft 362, a transmission gear 363, and a transmission bevel gear 364; the transmission fixed base 361 is fixed on the fixed disk 32, the transmission shaft 362 is rotatably connected to the transmission fixed base 361, the transmission gear 363 and the transmission bevel gear 364 are coaxially fixed on the transmission shaft 362 respectively, the transmission gear 363 meshes with the fixed rack 35, and the transmission bevel gear 364 meshes with the bevel ring 331.

[0037] In other designs, the tooth surface polishing mechanism 4 has two polishing surfaces, upper and lower. Specifically, the tooth surface polishing mechanism 4 includes a second cylinder 41, a second connecting plate 42, a second motor 43, a second bevel gear 44, a tooth surface connecting rod 45, a polishing fixing plate 4631, a fixing connecting rod 47, a third bevel gear 48, and a polishing plate 49. The second cylinder 41 is fixed on the frame 1, and the extension end of the second cylinder 41 is fixed to the second connecting plate 42. The second motor 43 is fixed on the second connecting plate 42, and the second bevel gear 44 is coaxially fixed on the output shaft of the second motor 43. The polishing fixing plate 4631 is provided with an annular groove. One end of the tooth surface connecting rod 45 is fixed on the second connecting plate 42, and the other end is slidably connected in the annular groove. Preferably, there are multiple tooth surface connecting rods 45. Two polishing fixing plates 4631 are provided opposite to each other and connected by the fixing connecting rod 47. The third bevel gear 48 is coaxially fixed on the fixing connecting rod 47 and meshes with the second bevel gear 44. The polishing plate 49 is fixed on the polishing fixing plate 4631. When in use, the tooth surface polishing mechanism 4 can avoid interference when the upper fixing mechanism 3 descends by controlling the extension and retraction of the second cylinder 41.

[0038] In addition, a tooth profile polishing mechanism 5 can be provided. The tooth profile polishing mechanism 5 is located on the frame 1. The tooth profile polishing mechanism 5 includes a polishing plate 49 controlled by a motor. Such structures are described extensively in the prior art, so they will not be described in detail here.

[0039] The aforementioned gear deburring device can automatically polish and deburr the other side after polishing and deburring the tooth surface on one side.

It should not be considered that the specific implementation of the present invention is limited to these descriptions.
