Description

Technical Field

[0001] The utility model relates to the technical field of precision gears, in particular to a gear milling device. Background Art

[0002] A gear is a mechanical component with teeth on a wheel rim that mesh continuously to transmit motion and power. Gears have been used in transmissions for a long time. The principle of gear cutting by generating, along with specialized machine tools and tools that utilize this principle, emerged in the late 19th century. With the development of production, the smooth operation of gears has become increasingly important. Gears can be categorized as spur gears, helical gears, internal gears, and herringbone gears. Herringbone gears, for example, have a tooth line composed of two helical gears on the left and right. Some gears do not generate thrust in the axial direction; herringbone gears have high contact ratios, low axial loads, high load-bearing capacity, and stable operation.

[0004] However, in the existing technology, when milling herringbone gears, an outer tooth is composed of two left and right helical teeth, with a turning point at a certain angle in the middle. When milling, the teeth are milled repeatedly, and iron filings are easily left at the turning points of the teeth. As the depth of the milling becomes deeper, more and more iron filings remain, which will affect the accuracy of the next milling. Utility Model Content

[0012] Preferably, a centering rod is movably clamped to the other end of each connecting column. A plurality of centering rods are divided into two groups and are movably clamped to both sides of the herringbone gear.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figure 1-4 As shown, the utility model provides a milling device, including a lifting device 1 and a herringbone gear 2, the inner top of the lifting device 1 is fixedly connected with a straightening mechanism 3, the inner movably connected with a milling mechanism 4, and one side of the milling mechanism 4 is fixedly connected with a chip flushing mechanism 5, the chip flushing mechanism 5 includes a milling body 52, the outer side of the milling body 52 is fixedly connected with a fixed plate 54, the middle part of the fixed plate 54 is fixedly connected with a coolant nozzle 53, one end of the coolant nozzle 53 is fixedly connected with an input hose 51, and the coolant nozzle 53 is at a certain angle to the milling cutter of the milling body 52.

[0025] The specific settings and functions of this embodiment are described below: By setting up the chip flushing mechanism 5, when the milling tooth main body 52 moves for milling teeth, it drives the fixed plate 54, and the fixed plate 54 drives the coolant nozzle 53 to move. The input hose 51 is connected to the coolant source. After being pressurized by the water pump, the coolant sprayed out by the coolant nozzle 53 is aligned at a certain angle with the tip of the milling cutter of the milling tooth main body 52, achieving cooling and at the same time flushing the milling tooth position, avoiding iron chips remaining at the tooth tip turning points, and improving the milling tooth accuracy.

[0026] Embodiment 2

[0027] As Figure 3 and Figure 4 As shown, a first servo motor 41 is fixedly connected to the middle of the milling tooth main body 52. A sliding block 42 is fixedly connected to one side of the first servo motor 41. An inner frame 45 is slidably connected inside the sliding block 42. One end of the inner frame 45 is fixedly connected to a second servo motor 44. A threaded rod 43 is fixedly connected to the rotating shaft of the second servo motor 44. The outer surface of the threaded rod 43 is threadedly connected to the upper inner part of the sliding block 42. A longitudinal movement component 46 is arranged on one side of the inner frame 45. C-shaped frames 31 are slidably connected inside both ends of the inner frame 45. A plurality of connecting columns 32 are fixedly connected to both ends of the C-shaped frames 31. The other end of each connecting column 32 is movably clamped with a centering rod 33. The plurality of centering rods 33 are divided into two groups and are movably clamped with both sides of the herringbone gear 2.

[0028] The overall effect achieved by this embodiment is that by fixedly clamping the herringbone gear 2 to the support column of the lifting device 1, the lifting device 1 raises the herringbone gear 2 into the centering mechanism 3, adjusts the angle of the centering rod 33, so that the centering rod 33 is clamped into the grooves on both sides of the herringbone gear 2, and with the help of tools, the centering rod 33 is tightened to the connecting column 32, thereby restricting the position of the herringbone gear 2, ensuring that the herringbone gear 2 will not be misaligned during the subsequent milling tooth process. Then, the first servo motor 41 is started, and its rotating shaft drives the milling tooth main body 52 to rotate a certain angle. The second servo motor 44 is started, driving the threaded rod 43 to rotate. The threaded rod 43 generates a meshing force when rotating inside the sliding block 42, causing the sliding block 42 to move on the rod part of the inner frame 45, adjusting the position of the milling teeth. Similarly, when the longitudinal movement component 46 is started, it drives the inner frame 45 to move on the rod part of the C-shaped frame 31. The two-directional movement drives the milling tooth main body 52 to perform milling teeth, realizing the milling of the herringbone gear.

[0029] Usage method and working principle of this device: When using this gear milling device, first, fixedly clamp the herringbone gear 2 onto the support column of the lifting device 1. The lifting device 1 raises the herringbone gear 2 into the alignment mechanism 3. Adjust the angle of the alignment rod 33 so that the alignment rod 33 is stuck into the grooves on both sides of the herringbone gear 2. With the help of tools, tighten the alignment rod 33 onto the connecting column 32, thereby restricting the position of the herringbone gear 2 and ensuring that the herringbone gear 2 will not be misaligned during the subsequent gear milling process. Then, start the first servo motor 41, and its rotating shaft drives the gear milling main body 52 to rotate a certain angle. Start the second servo motor 44, which drives the threaded rod 43 to rotate. The threaded rod 43 rotates inside the sliding block 42 to generate a meshing force, causing the sliding block 42 to move on the rod part of the built-in frame 45 and adjust the position of the gear milling. Similarly, start the longitudinal movement component 46, which drives the built-in frame 45 to move on the rod part of the C-shaped frame 31. The two-direction movement drives the gear milling main body 52 to perform gear milling. At the same time, when the gear milling main body 52 moves, it drives the fixing plate 54, and the fixing plate 54 drives the coolant nozzle 53 to move. The input hose 51 is connected to the coolant source. After being pressurized by the water pump, the coolant sprayed by the coolant nozzle 53 is aligned at a certain angle with the tip of the milling cutter of the gear milling main body 52, achieving cooling and temperature reduction while flushing the gear milling position, avoiding iron filings remaining at the tooth crest turning points, and improving the gear milling accuracy.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
