Description

Technical Field

[0001] This utility model relates to the field of gear ring production technology, and in particular to a gear hobbing device for gear ring production. Background Technology

[0002] The gear hobbing device is the core mechanism in a gear hobbing machine responsible for completing the gear ring cutting process. It utilizes the relative motion between the hob and the workpiece to continuously cut and machine precise tooth profiles on the gear ring blank, forming the required tooth shape.

[0003] In the prior art, some gear hobbing devices used for gear ring production have a hob that is equivalent to a small gear, while the gear ring blank to be processed is equivalent to a large gear. While the hob rotates at high speed, it gradually removes material along the gear ring to form the required tooth shape. However, some gear hobbing devices for gear ring production cannot fix gear ring blanks of different sizes when faced with them. It is necessary to change the fixing device before processing, which reduces the overall processing efficiency and the applicability of the device. Utility Model Content

One end of the elastic telescopic rod 35 is fixedly connected to the inner wall of the limiting plate 34 for intermittently starting the oil pump 31.

[0037] Working principle: The support plate 5 is squeezed to deform the damper 4. The gear ring 7 to be processed is placed on the support plate 5. At this time, the support plate 5 is released, and the squeezed damper 4 begins to rebound, which drives the threaded plate 6 connected to the top of the support plate 5 to abut against the inner wall of the gear ring 7. Then, the disc 8 is placed on the top of the rotating shaft 3. The disc 8 and the rotating shaft 3 are fixedly connected by the bolt 9. The threaded plate 11 is stretched to deform the telescopic rod 10, which gives the threaded plate 11 a force in the direction of the rotating shaft 3, so that the threaded plate 11 and the threaded plate 6 are threaded together, so that the threaded plate 11 and the threaded plate 6 are locked together, thereby achieving the effect of fixing the gear ring 7 to be processed. Since the damper 4 and the telescopic rod 10 are adjustable, they can be adapted to gear rings 7 of different sizes.

[0038] Before processing, start cylinder 13 to extend and retract telescopic rod 14, which in turn drives motor 15 to slide along slide rail 12. Adjust the position of motor 15 and start motor 15 to drive rotating shaft 16 to rotate, which in turn drives threaded rod 17 to rotate. This causes lifting plate 18 on threaded rod 17 to move along limiting rod 19, positioning lifting plate 18 above the gear ring 7 to be processed. Then, start motor 22 to drive rotating shaft 23 to rotate, which in turn drives hob 24 to rotate at high speed. Start motor 15 and adjust the position of lifting plate 18 to lower it, causing hob 24 to lower as well. Simultaneously, hob 24 cuts the gear ring 7 to be processed, creating teeth.

[0039] When the teeth of the gear ring 7 to be processed are cut, the motor 2 is started, driving the rotating shaft 3 to rotate. This, in turn, drives the damper 4 and the support plate 5, causing the gear ring 7 to rotate, moving the cut-out teeth away so that the adjacent uncut portion is below the hob 24. Simultaneously, the rotation of the rotating shaft 3 drives the gear 37 to rotate, with the teeth of the gear 37 spaced at intervals that correspond to the rotation angle of the rotating shaft 3. When the gear 37 rotates, its teeth touch the switch 36, causing it to slide within the limiting plate 34 and compress the elastic telescopic rod 35, causing it to deform. The switch 36 then controls the oil pump 31 to start. The started oil pump 31 draws lubricating oil from the lubricating oil tank 33 through the pipe 32, and continues to transport it through the oil delivery pipe 30 to the lubricating oil box 26. The lubricating oil is then sprayed out through the nozzle 27 to lubricate the roller cutter 24 and protect it so that it can continue to cut. After the oil pump 31 has been running for a period of time, as the gear 37 continues to rotate, the distance between the teeth of the gear 37 and the switch 36 will become smaller and smaller until they disengage. At this time, the elastic telescopic rod 35 begins to rebound, driving the limiting plate 2 34 back to its original position. At this time, the switch 36 controls the oil pump 31 to stop. Therefore, the lubrication of the roller cutter 24 is intermittent, which will not waste lubricating oil and will ensure that the roller cutter 24 will not be damaged due to excessive friction.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
