Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and more specifically, to a polishing device for gear shafts. Background Technology

[0002] A gear shaft is a rotating support component, and its sections can have different diameters. After rough machining, the surface of the gear shaft is often very rough. To make the surface smooth, bright, and more precise, polishing is required. However, in the existing technology, the polishing of gear shafts is generally done by hand-held polishing devices. Prolonged hand-held polishing increases the labor intensity of the workers. Furthermore, hand-held polishing may result in some parts not being polished, and the polishing effect may be inconsistent, thus reducing the polishing effect of the gear shaft. Based on this, the present invention designs a gear shaft polishing processing device to solve the above problems. Utility Model Content

[0021] Example: Please refer to Figure 1-6 A polishing device for a gear shaft includes a base plate 1, a mounting box 2 fixedly connected to the top of the base plate 1, a moving component 3 disposed in the inner cavity of the mounting box 2, the moving component 3 penetrating the mounting box 2 and connected to a polishing device 5, and a rotating component 4 disposed above the mounting box 2, the rotating component 4 penetrating the mounting box 2 and connected to the moving component 3.

[0022] The moving component 3 includes a threaded rod 31 rotatably connected to the inner wall of the mounting box 2. One end of the threaded rod 31 passes through the mounting box 2 and is provided with a drive component. A threaded seat 32 is threadedly connected to the outer side of the threaded rod 31. A U-shaped frame 33 is fixedly connected to the threaded seat 32 passing through the mounting box 2. The U-shaped frame 33 is rotatably connected to the grinding device 5. A guide seat 34 is fixedly connected to the outer side of the U-shaped frame 33. A guide rod 35 is slidably connected to the outer side of the guide seat 34. Both ends of the guide rod 35 are fixedly connected to the mounting box 2. The drive component includes a motor 36 fixedly mounted above the base plate 1. A drive wheel 37 is fixedly connected to the output shaft of the motor 36. A belt 38 is sleeved on the outer side of the drive wheel 37. A driven wheel 39 is connected to the drive wheel 37 through the belt 38. A drive shaft 310 is fixedly connected to the outer side of the driven wheel 39. The drive shaft 310 passes through the mounting box 2 and is fixedly connected to the threaded rod 31.

[0023] Specifically, when polishing is required on the gear shaft, the rotating assembly 4 is controlled to operate, and then the motor 36 is turned on, causing the motor 36 to drive the drive wheel 37, which is fixedly connected to its output shaft, to rotate. When the drive wheel 37 rotates, it drives the driven wheel 39 to rotate via the belt 38. When the driven wheel 39 rotates, it drives the drive shaft 310, which is fixedly connected to it, to rotate. This causes the drive shaft 310 to drive the threaded rod 31, which is fixedly connected to it, to rotate. When the threaded rod 31 rotates, it drives the threaded seat 32, which is threadedly connected to it, to move. When the threaded seat 32 moves, it drives the U-shaped frame 33, which is fixedly connected to it, to move synchronously. This allows the rotating assembly 4 to polish the gear shaft.

[0024] The rotating assembly 4 includes a mounting bracket 41 and a mounting bracket 47 fixedly connected above the mounting box 2. A transmission assembly is provided on the side of the mounting bracket 47 near the mounting bracket 41. A connecting sleeve 42 is fixedly connected to the outer side of the mounting bracket 41. A spring 43 is provided inside the connecting sleeve 42. One end of the spring 43 is fixedly connected to the connecting sleeve 42, and the other end of the spring 43 is fixedly connected to a connecting plate 44. A movable rod 45 is fixedly connected to the outer side of the connecting plate 44. The movable rod 45 passes through the connecting sleeve 42 and is rotatably connected to a rotating disk 46. The transmission assembly includes a rotating rod 48 rotatably connected to the outer side of the mounting bracket 47. One end of the rotating rod 48 is fixedly connected to a fixed disk 49, and the other end of the rotating rod 48 is fixedly connected to a driven wheel 410. A belt 411 is sleeved on the outer side of the driven wheel 410, and the driven wheel 410 is connected to a driving wheel 412 through the belt 411. A mounting shaft 413 is fixedly connected to the outer side of the driving wheel 412. The mounting shaft 413 is rotatably connected to the mounting box 2, and a full gear 414 is fixedly connected to the outer side of the mounting shaft 413. A residual gear 415 meshes with the outer side of the full gear 414. A linkage shaft 416 is fixedly connected to the outer side of the residual gear 415. The linkage shaft 416 passes through the mounting box 2 and is fixedly connected to the threaded rod 31.

[0025] Specifically, pressing the rotating disk 46 near the mounting bracket 41 causes the rotating disk 46 to move the movable rod 45 fixedly connected to it. When the movable rod 45 moves, it causes the connecting plate 44 fixedly connected to it to move synchronously, thereby compressing the spring 43 fixedly connected to it. Then, the gear shaft is placed between the rotating disk 46 and the fixed disk 49. The rotating disk 46 is then released, causing the rotating disk 46 to press the gear shaft tightly through the elastic force of the spring 43. When the threaded rod 31 rotates, it causes the linkage shaft 416 fixedly connected to it to rotate, thereby causing the linkage shaft 416 to drive the residual gear 415 fixedly connected to it to rotate. When the residual gear 415 rotates, it drives the full gear 414 that meshes with it to rotate, which in turn drives the mounting shaft 413 that is fixedly connected to it to rotate. When the mounting shaft 413 rotates, it drives the driving wheel 412 that is fixedly connected to it to rotate, which in turn drives the driven wheel 410 to rotate via the belt 411. When the driven wheel 410 rotates, it drives the rotating rod 48 that is fixedly connected to it to rotate, which in turn drives the fixed disk 49 that is fixedly connected to it to rotate. When the fixed disk 49 rotates, it drives the gear shaft to rotate synchronously, thereby polishing the gear shaft.
