Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear chamfering device. Background Technology

[0002] Gears are commonly used mechanical transmission parts. During the processing of gears, chamfering is required on both sides of the edges to prevent the sharp corners from breaking during meshing. For example, some gears in a transmission use rounded and sharp corners for smooth and easy shifting. Therefore, the accuracy and consistency of the chamfering directly affect the shifting quality, and a chamfering device is needed for gear chamfering.

[0003] However, existing technologies have some problems: although existing chamfering devices can automatically chamfer gears, in actual use, workers need to fix the gear, chamfer the edge of its top surface first, and then remove the gear, flip it over, and fix it again before chamfering the other side of the gear can continue. This not only increases the workload of workers but also reduces processing efficiency. Therefore, we propose a gear chamfering device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a gear chamfering device that simultaneously chamfers the edges of both sides of the gear, thereby improving overall processing efficiency.

[0005] The purpose of this utility model is achieved as follows: A gear chamfering device includes a base, a brake motor fixedly mounted on the bottom of the base, the output shaft of the brake motor connected to a rotating shaft via a coupling, the top of the rotating shaft penetrating the base and fixedly connected to a disc, a top plate fixedly mounted on the disc, and a clamping assembly provided on the top plate for limiting and fixing the gear, a square frame fixedly mounted on the top of the base, a first slider and a second slider slidably connected to the two sides of the inner wall of the square frame respectively, a sliding plate slidably connected to the first slider, a drive motor fixedly mounted on both the sliding plate and the second slider, the output shaft of the drive motor connected to a round shaft via a coupling, a grinding wheel fixedly sleeved on the outer surface of the round shaft, and the first slider and the second slider also connected to the base via a drive assembly for adjusting the distance between the first slider and the second slider.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown in the figure, a gear chamfering device provided in this embodiment of the present invention includes a base 1, a brake motor 2 fixedly installed at the bottom of the base 1, the output shaft of the brake motor 2 connected to a rotating shaft 3 via a coupling, the top of the rotating shaft 3 penetrating the base 1 and fixedly connected to a disc 4, a top plate 5 fixedly installed on the disc 4, and a clamping assembly provided on the top plate 5 for limiting and fixing the gear, a square frame 6 fixedly installed on the top of the base 1, a first slider 7 and a second slider 8 slidably connected to the two sides of the inner wall of the square frame 6 respectively, a slide plate 9 slidably connected to the first slider 7, and a drive motor 10 fixedly installed on both the slide plate 9 and the second slider 8, the output shaft of the drive motor 10 connected to a round shaft 11 via a coupling, a grinding wheel 12 fixedly sleeved on the outer surface of the round shaft 11, the first slider 7 and the second slider 8 are also connected to the base 1 via a drive assembly, the drive assembly being used to adjust the distance between the first slider 7 and the second slider 8.

[0022] The operator uses a clamping assembly to fix the gear to be processed onto the top plate 5, then starts the drive motor 10 to make the round shaft 11 drive the grinding wheel 12 to rotate. The two grinding wheels 12 are located on the upper and lower sides of the gear, respectively. The drive assembly then moves the first slider 7 and the second slider 8 closer to each other, so that the two grinding wheels 12 can grind and chamfer the edges of the upper and lower sides of the gear. The brake motor 2 then rotates the gear, which can quickly chamfer the edges of the two sides of the gear, thus improving work efficiency.

[0023] Furthermore, the drive assembly includes a first hydraulic cylinder 13, which is fixedly mounted on the base 1. The telescopic end of the first hydraulic cylinder 13 is fixedly connected to a lifting block 14. Both sides of the front of the lifting block 14 are hinged with connecting rods 15, and the other ends of the two connecting rods 15 are respectively hinged to the first slider 7 and the second slider 8.

[0024] By activating the first hydraulic cylinder 13, the lifting block 14 can drive the connecting rod 15 to move. When the lifting block 14 moves upward, the connecting rod 15 can drive the first slider 7 and the second slider 8 to move closer to each other, so that the grinding wheel 12 can move closer to the gear for grinding and chamfering. The operator can also move the lifting block 14 downward to increase the distance between the two grinding wheels 12, so that larger gears can be chamfered, thus improving applicability.

[0025] Furthermore, a second hydraulic cylinder 16 is fixedly installed on the first slider 7, and the telescopic end of the second hydraulic cylinder 16 is fixedly connected to the slide plate 9.

[0026] By activating the second hydraulic cylinder 16, the slide plate 9 can drive the drive motor 10 on its surface to move up or down, thereby adjusting the height of the grinding wheel 12 on the top of the gear, and thus enabling chamfering of gears of different thicknesses.

[0027] Furthermore, the top plate 5 has a top hole 17, and the clamping assembly includes a guide rod 18. The guide rod 18 is fixedly installed on the inner wall of the top hole 17. Clamping plates 19 are movably sleeved on both sides of the outer surface of the guide rod 18, and inclined plates 20 are fixedly connected to the bottom of the clamping plates 19.

[0028] By attaching the gear to the outside of the two clamping plates 19 and then moving the two clamping plates 19 in opposite directions, the clamping plates 19 can limit and fix the gear, thereby ensuring the stability of the gear during the chamfering operation.

[0029] Furthermore, a third hydraulic cylinder 21 is fixedly installed on the top of the disc 4, and a push-pull plate 22 is fixedly connected to the telescopic end of the third hydraulic cylinder 21. The push-pull plate 22 is movably sleeved on the outer surface of the inclined plate 20.

[0030] By activating the third hydraulic cylinder 21, the push-pull plate 22 moves upward, thereby squeezing the outer surface of the inclined plate 20, which in turn causes the two inclined plates 20 to drive the two clamping plates 19 to move in opposite directions to clamp and fix the gear.

[0031] Furthermore, the opposing surfaces of the two clamping plates 19 are set in an arc shape, and the opposing surfaces of the two clamping plates 19 are provided with anti-slip texture.

[0032] By setting anti-slip texture on the surface of the clamp 19, its limiting and fixing effect on the gear can be improved.

[0033] Working principle and usage process of this utility model:

[0034] First, the worker places the gear on the top plate 5, then activates the third hydraulic cylinder 21 to move the push-pull plate 22 upward, thereby causing the two clamping plates 19 to move in opposite directions to limit and fix the gear. Then, the position of the slide plate 9 is adjusted according to the thickness of the gear. The height of the slide plate 9 can be adjusted by the second hydraulic cylinder 16. After adjustment, the worker starts the drive motor 10, causing the round shaft 11 to drive the grinding wheel 12 to rotate. Then, the first hydraulic cylinder 13 is activated to move the lifting block 14 upward, which in turn drives the first slider 7 and the second slider 8 to move in opposite directions through the connecting rod 15. This allows the two grinding wheels 12 to approach the upper and lower surfaces of the gear for grinding and chamfering. During the grinding process, the worker can also activate the brake motor 2 to make the rotating shaft 3 drive the disc 4 to rotate slowly, thereby grinding the edges of both sides of the gear as a whole, improving processing efficiency.

[0035] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
