The feeding mechanism is used for clamping, moving, and positioning the planetary gear, and uses a hydraulic telescopic box and a clamping plate to accurately position and clamp the planetary gear. It adjusts the drilling angle and range through the telescopic crank arm, and combines the drill rod mechanism and the feeding mechanism to achieve efficient and precise drilling of the planetary gear, effectively improving work efficiency and product quality, while reducing production costs and operation difficulties; The prior art (Chinese Patent with Publication No. CN119036111A and Publication Date of November 29, 2024) discloses a gear drilling tooling for a vertical machining center, including: a mounting plate with a plurality of positioning holes; three mounting shafts perpendicular to the mounting plate, and a clamping gear is detachably and fixedly connected to the mounting shaft.

As the receiving seat continues to move upward, the roller on its outer side will contact and push the wear-resistant plate, so that the wear-resistant plate drives the adjustment seat to slide and adjust, thereby making multiple positioning teeth move and engage in the corresponding tooth grooves of the gear to achieve locking and positioning of the gear.

[0016] 3. A positioning tooth, a movable plate and a pull rope are provided. When the positioning tooth contacts the tooth block of the gear during movement, the inclined surface of the positioning tooth is subjected to resistance force, pushing the positioning tooth to move upward elastically. At this time, the slider drives the movable plate to move upward synchronously through the telescopic column. At this time, the movable plate uses the pull rope to pull the frame plate and the rotating column to rotate elastically, thereby achieving fine-tuning of the gear angle. When the tooth groove of the gear is close to the positioning tooth, the positioning tooth will move down and reset again, and be stuck in the corresponding tooth groove, thereby achieving locking of the gear. There is no need for manual pre-adjustment of the gear placement position, which further improves the positioning and drilling efficiency of the gear. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: In the process of using the existing gear drilling machine, the positioning direction of the gear is single and the operation is relatively cumbersome. To solve this technical problem, the following technical content is disclosed in this embodiment. Please refer to Figures 1-5 as shown; A gear drilling machine with quick positioning includes a vertically arranged frame 1. A horizontal cross frame 7 is fixedly installed at the lower end of the frame 1. Adjusting mechanisms are provided on both the frame 1 and the cross frame 7. A first mounting plate 5 and a second mounting plate 8 are respectively installed on the two adjusting mechanisms. At the same time, a drilling machine 6 and a fixed seat 9 are fixedly installed on the first mounting plate 5 and the second mounting plate 8 respectively; A movable frame 10 is rotatably installed on the fixed seat 9. A second motor 11 is fixedly installed inside the fixed seat 9. The output end of the second motor 11 is fixedly installed with the movable frame 10. A rotating column 12 is elastically rotatably installed at the central position of the movable frame 10. At the same time, a frame plate 13 is fixedly installed at the upper end of the rotating column 12. A positioning component for initially positioning the gear is installed on the frame plate 13. Locking components for engaging with the tooth grooves are evenly installed on the movable frame 10.

[0021] The adjusting mechanism includes two first motors 2 and guide rods 4 respectively and fixedly installed on the frame 1 and the cross frame 7. A lead screw 3 is fixedly installed at the output end of the first motor 2. The two lead screws 3 are respectively threadedly connected to the first mounting plate 5 and the second mounting plate 8. At the same time, the first mounting plate 5 and the second mounting plate 8 are slidably arranged outside the guide rod 4. The frame plate 13 is coaxially arranged with the gear to be processed. The positioning assembly includes a hydraulic cylinder 14 fixedly installed on the upper surface of the lower end of the movable frame 10. The upper end of the hydraulic cylinder 14 is fixedly connected with a receiving seat 15. At the same time, the receiving seat 15 is sleeved outside the pushing member 17. A buffer spring 16 is fixedly connected between the receiving seat 15 and the pushing member 17. At the same time, the pushing member 17 is slidably sleeved outside the rotating column 12. The frame plate 13 is evenly provided with sliding grooves 18. The positioning assembly further includes a sliding plate 19 slidably installed in the sliding grooves 18. A first guide post 20 is horizontally fixedly installed at the lower part of the sliding plate 19. At the same time, the first guide post 20 is telescopically connected with the frame plate 13. A first return spring 21 is connected between the sliding plate 19 and the frame plate 13. The upper part of the pushing member 17 is arranged in a conical structure. When the pushing member 17 moves upward, it contacts the lower end of the sliding plate 19 and pushes the sliding plate 19 to slide along the sliding groove 18. A limiting member 22 is elastically rotatably installed at the top of the sliding plate 19. The limiting member 22 is arranged in an arc structure. When the sliding plate 19 moves close to the gear, the lower end of the limiting member 22 contacts the inner ring of the gear and rotates. At the same time, the upper end of the limiting member 22 presses down and fits on the upper surface of the gear. The locking assembly includes a second guide post 24 slidably installed on the movable frame 10. A wear-resistant plate 26 is fixedly installed at the end of the second guide post 24 away from the gear. The lower part of the wear-resistant plate 26 is arranged in an inclined structure. At the same time, a roller 23 is rotatably installed outside the receiving seat 15. When the receiving seat 15 drives the roller 23 to move upward, it rolls along the outside of the wear-resistant plate 26. A second return spring 2601 is fixedly connected between the movable frame 10 and the wear-resistant plate 26. An adjusting seat 25 is fixedly installed at the end of the second guide post 24 close to the gear. A slider 27 is installed in the groove opened on the adjusting seat 25 in a lifting and sliding manner. A positioning tooth 28 is fixedly connected to the outside of the slider 27 by bolts. When the adjusting seat 25 moves, the positioning tooth 28 is driven to engage with the tooth groove of the gear.

[0022] When drilling a gear, place the gear to be processed above the support plate 13 so that the central hole of the gear is sleeved outside the sliding plate 19. Then, control the hydraulic cylinder 14 to push the receiving seat 15 upward. At this time, the receiving seat 15 will drive the pushing member 17 to move upward synchronously through the buffer spring 16, so that the conical surface at the upper end of the pushing member 17 contacts and pushes the lower part of the sliding plate 19 to slide along the chute 18. At the same time, the first guide post 20 on the pushing member 17 and the support plate 13 are telescopically adjusted. As the sliding plate 19 moves, the limiting member 22 connected to its upper end will gradually approach the central hole of the gear. At this time, the lower end of the limiting member 22 will first contact the inner wall of the central hole of the gear, so that the limiting member 22 rotates elastically. During the rotation of the limiting member 22, its upper end will contact and press the upper surface of the gear, thereby realizing the position correction and preliminary positioning of the gear, ensuring that the gear and the support plate 13 are coaxial. When the pushing member 17 cannot move upward, the hydraulic cylinder 14 will push the receiving seat 15 to continue moving upward, so that the roller 23 outside the receiving seat 15 will contact the wear-resistant plate 26, thereby pushing the wear-resistant plate 26 to slide toward the gear. At this time, the wear-resistant plate 26 will drive the adjusting seat 25 to move synchronously through the second guide post 24, so that the positioning teeth 28 outside the adjusting seat 25 can be inserted into the tooth grooves of the gear to realize the locking of the gear, so as to ensure the positioning stability of the gear. Subsequently, control the first motor 2 on the frame 1 to drive the lead screw 3 to rotate, which can drive the first mounting plate 5 to move up and down along the guide rod 4, so that the drilling machine 6 on the first mounting plate 5 moves downward to realize drilling of the gear. And controlling the movement of the second mounting plate 8 on the cross frame 7 can adjust the position of the gear. Subsequently, control the second motor 11 to drive the movable frame 10 to rotate, which can adjust the angle of the gear, and then conveniently adjust the drilling position of the gear.

[0023] Embodiment 2: The technical content disclosed in this embodiment is a further improvement based on the above Embodiment 1. When the existing gear drilling machine positions, it is inconvenient to automatically adjust the angle of the gear and needs to be manually adjusted in advance, which reduces the processing efficiency. To further solve this technical problem, the following technical content is disclosed in this embodiment, as Figures 6-9As shown in the figure; a fine-tuning mechanism for driving the rotation and fine-tuning of the gear to be processed is connected between the locking component and the movable frame 10. The fine-tuning mechanism includes a telescopic column 29 vertically and fixedly installed on the lower surface of the slider 27, and the telescopic column 29 penetrates through the lower end of the adjusting seat 25, and the lower end of the telescopic column 29 is arranged in a spherical structure. At the same time, a third return spring 30 is connected between the slider 27 and the adjusting seat 25. The fine-tuning mechanism further includes a third guide post 31 fixedly installed on the lower surface of the upper part of the movable frame 10, and a movable plate 32 is sleeved on the outside of the third guide post 31 for lifting and lowering. And a fourth return spring 33 is fixedly connected between the movable frame 10 and the movable plate 32. The side of the positioning tooth 28 facing the gear is arranged in an inclined surface structure, and when the positioning tooth 28 contacts the tooth block of the gear and is pressed, it rises and adjusts. The movable plate 32 is arranged in a U-shaped structure, and the lower end of the telescopic column 29 slides and lifts and adjusts in the groove of the movable plate 32. And when the telescopic column 29 rises, it drives the movable plate 32 to move up synchronously. A pull rope 34 is fixedly connected to the outside of the movable plate 32, and one end of the pull rope 34 away from the movable plate 32 is fixedly connected to the outside of the frame plate 13, and the pull rope 34 is inclined between the frame plate 13 and the movable plate 32. At the same time, when the movable plate 32 moves up, it drives the frame plate 13 and the rotating column 12 to elastically rotate through the pull rope 34.

[0024] During the movement of the adjusting seat 25, the connected telescopic column 29 will slide along the groove of the movable plate 32. When the positioning tooth 28 contacts the tooth block part of the gear during the movement, the tooth block of the gear will exert force on the inclined surface of the positioning tooth 28, thereby pushing the positioning tooth 28 to move up. At this time, the positioning tooth 28 will drive the slider 27 to elastically move up in the groove of the adjusting seat 25, so that the slider 27 drives the movable plate 32 to elastically lift and adjust through the telescopic column 29. At this time, the movable plate 32 will drive the frame plate 13 and the rotating column 12 to elastically rotate through the pull rope 34 on its outside, and then finely adjust the rotation of the gear limited on the frame plate 13. When the tooth groove of the gear moves to the outside of the positioning tooth 28, the positioning tooth 28 will elastically reset and snap into the tooth groove of the gear, thereby realizing the adjustment and locking of the gear, effectively improving the positioning convenience and stability of the gear.

[0025] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
