Description

Technical Field

[0001] The utility model relates to a gear processing device, in particular to an oil immersion device for gear production. Background Art

[0002] After the gear is processed, in order to increase the protection of the gear, an oil immersion process will be carried out on the gear so that the surface of the gear can be coated in a hollow container, and then the container and the gear are placed together in an oil pool with oil for oil immersion work. After the oil immersion is completed, the container and the gear are taken out together; however, in the specific operation process of such an oil immersion method, since the gears are placed together in the container, the area where the gears located inside, especially the gears in the middle, fit together with other gears is relatively large. Coupled with the extrusion of the outer gears, it is difficult for the oil in the oil pool to enter between the gears, resulting in incomplete oil immersion and poor overall oil immersion effect. Therefore, there is a problem of poor oil immersion effect when using the existing oil immersion device for gear processing to carry out oil immersion work. Summary of the Utility Model

[0022] Working principle: When specifically performing the oil immersion operation, first connect the entire device to the external safe mains power supply. Then, place the gear to be oil-immersed in the loading channel 14, and pour the oil for the oil immersion operation into the oil immersion tank 2 so that the oil immersion tank 2 stores an appropriate amount of oil. Next, control the loading cylinder 15 to start. After the loading cylinder 15 starts, it will drive the loading member 16 to move along the loading channel 14 towards the mounting plate 3. During the movement of the loading member 16, it will push the gears in the loading channel 14 to move together, so that the frontmost gear contacts the material clamping ring seat 11 on the opposite side of the loading channel 14 and is pushed onto the material clamping ring seat 11. At this time, control the loading cylinder 15 to pause, and then control the driving motor 6 and the gearbox to start for a certain period of time. After the driving motor 6 and the gearbox start, they will drive the drive shaft 5 to rotate. After the drive shaft 5 rotates, it will drive the drive plate 7 to rotate. After the drive plate 7 rotates, it will drive the material discharging base 8 to rotate, so that the material discharging base 8 drives the gear to rotate towards the oil immersion tank 2, and the empty material discharging base 8 behind will move to the opposite side of the loading channel 14. When the empty material discharging base 8 behind moves to the opposite side of the loading channel 14, the starting time of the driving motor 6 just arrives, the driving motor 6 stops, and then control the loading cylinder 15 to start again, push the frontmost gear in the loading channel 14 onto the material discharging base 8, and then control the loading cylinder 15 to stop again and the driving motor 6 to start. Repeat this operation to achieve the single-piece loading of the gears.

[0023] After the driving plate 7 drives the gear to move into the oil immersion tank 2 through the feeding base 8, the oil in the oil immersion tank 2 enters and covers the surface of the gear. At the same time, part of the oil will enter between the driving gear 9 and the gear through the oil holes 10 on the driving gear 9, so that the oil can better and more comprehensively cover the surface of the gear, thus ensuring the oil immersion effect of the gear. As the driving plate 7 drives the gear to rotate, the driving gear 9 on the feeding base 8 will contact the arc-shaped rack 4 directly below on the mounting plate 3. At this time, once the feeding base 8 rotates, meshing transmission will occur between the driving gear 9 and the arc-shaped rack 4, thereby causing the driving gear 9 to rotate. After the driving gear 9 rotates, it will drive the gear to rotate together. When the gear rotates, it will drive the surrounding oil to flow, so that the oil can better enter between the teeth or some grooves of the gear, thus ensuring the oil immersion effect. After the gear completes the oil immersion work, the gear will leave the oil immersion tank 2 as the driving plate 7 rotates. At this time, the excess oil on the gear will slowly drip back into the oil immersion tank 2. At the same time, as the driving plate 7 continues to rotate, the driving gear 9 on the feeding base 8 will contact the arc-shaped rack 4 located above on the mounting plate 3. At this time, using the meshing transmission between the arc-shaped rack 4 and the driving gear 9, the gear can be driven to rotate. By the rotation of the gear, the excess oil can be evenly dropped back into the oil immersion tank 2 as the gear rotates, while ensuring that the oil can evenly cover the surface of the gear, thus ensuring the oil immersion effect.

[0024] When the gear moves to the opposite side of the feeding channel 19 as the driving plate 7 rotates, the feeding operation can be carried out. At this time, control the feeding cylinder 21 to start for a certain period of time. After the feeding cylinder 21 starts, it will drive the feeding plate 22 to move towards the driving plate 7. During the movement of the feeding plate 22, the feeding pusher 23 will be driven to move, so that the feeding pusher 23 contacts the gear through the channel. Finally, the gear is pushed away from the material clamping ring seat 11 and into the feeding channel 19 by the feeding pusher 23. Then control the feeding cylinder 21 to stop to complete the feeding work.
