Description

Technical Field

[0001] This utility model relates to the field of planetary gear shaft machining technology, and in particular to a drilling device for planetary gear shaft machining. Background Technology

[0002] Planetary gears are gear systems that, in addition to rotating around their own axis of rotation like fixed-axis gears, also have their axis of rotation rotate around the axes of other gears along with the planet carrier. When machining planetary gear shafts, it is necessary to drill holes in them, so a drilling device is required.

[0003] The patent with publication number CN212761247U discloses a drilling device for machining planetary gear shaft holes, including a worktable. Support columns are fixedly connected to both sides of the upper surface of the worktable. A placement plate is fixedly connected to the end of the support column away from the worktable. A fixing hole is opened in the middle of the upper surface of the placement plate. A threaded column is threadedly connected inside the fixing hole. A fixing plate is fixedly connected to one end of the threaded column. A sliding sleeve is sleeved on the outer surface of the support column.

[0004] In the above case, the positioning plate is pressed down by a spring to fix the gear. However, the clamping force is insufficient and it is not possible to fix the round rod-shaped gear shaft by drilling holes, which makes the device impractical.

[0005] Therefore, this utility model provides a drilling device for machining planetary gear shafts to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to provide a drilling device for machining planetary gear shafts, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for machining planetary gear shafts, comprising a worktable, a fixed platform abutting the top of the worktable, and sliding grooves at both ends of the fixed platform. A sliding seat is slidably connected to the inner side of each sliding groove, and a fixed base is fixedly connected to the top of the sliding seat. An annular groove is formed on the inner side of the top of the fixed base, and a gear ring is rotatably connected to the inner side of the annular groove. Several drive rods are rotatably connected to the outer side of the fixed base, and a drive gear is fixedly connected to the middle of the outer side of each drive rod. The drive gear meshes with the outer side of the gear ring. The drive rod has opposite threads at both ends on its outer side. Internal threaded blocks are threaded to both ends of the drive rod's outer side. Rotating rods are rotatably connected to the bottom of each of the two internal threaded blocks. The same clamping block is rotatably connected to the other end of each of the two rotating rods. A bidirectional screw is rotatably connected to the bottom of the fixed platform. Two sliding seats are threaded to the two ends of the bidirectional screw's outer side. A lead screw is rotatably connected to the top of the worktable. Mating blocks are fixedly connected to both ends of the fixed platform near the lead screw. Two mating blocks are threaded to the outside of the lead screw. A punching seat is fixedly connected to the middle of the top of the worktable.

[0008] In a preferred embodiment, the workbench is fixedly connected to legs on all four sides of its bottom, and the fixed platform includes bottom blocks at both ends of the bottom.

[0009] In a preferred embodiment, a side rod is fixedly connected to the top of the worktable away from the lead screw, and the fixed table is slidably connected to the outside of the side rod at the end away from the lead screw.

[0010] In one preferred embodiment, a No. 1 motor is fixedly connected to the top of the workbench, and its output end is fixedly connected to a lead screw.

[0011] In a preferred embodiment, a second motor is fixedly connected to the bottom of the fixed platform, and its output end is fixedly connected to a bidirectional screw. A third motor is fixedly connected to one side of the fixed base, and a side gear is fixedly connected to its output end. The side gear meshes with a gear ring.

[0012] In a preferred embodiment, the number of drive rods is three, which are distributed in a ring outside the gear ring, and the drive gear is located outside the annular groove.

[0013] In a preferred embodiment, the number of clamping blocks is three, which are arranged in a ring on the inner side of the top of the fixing base, and a soft pad is fixedly connected to the inner side of each clamping block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting up a gear ring, a drive rod, an internal screw block, and a clamping block, enables the gear ring to drive multiple drive gears, causing the drive rod to rotate synchronously. The internal screw blocks and rotating rods on both sides drive the clamping blocks to move inward synchronously, fixing the two ends of gears of different sizes. This allows the device to clamp round rod-shaped gear shafts and is compatible with gear shafts of various specifications, thus improving the applicability of the device.

[0016] This utility model, by setting up a shifting seat, a bidirectional screw, and a lead screw, allows the device to drive the fixed seats on both sides to move synchronously via the bidirectional screw, so as to fix gear shafts of different lengths. Through the cooperation of the lead screw and the mating block, the fixed platform and the gear shaft fixed on it can be driven to move, which facilitates drilling holes in different parts of the gear shaft in a fixed state, thereby improving the applicability of the device and speeding up the work efficiency.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a drilling device for machining planetary gear shafts, including a worktable 1, a fixed platform 2 abutting the top of the worktable 1, and a shifting groove 3 at both ends of the fixed platform 2. A shifting seat 4 is slidably connected to the inner side of the shifting groove 3, and a fixed seat 5 is fixedly connected to the top of the shifting seat 4. An annular groove 6 is opened on the inner side of the top of the fixed seat 5, and a gear ring 7 is rotatably connected to the inner side of the annular groove 6. Several drive rods 8 are rotatably connected to the outer side of the fixed seat 5, and a drive gear 9 is fixedly connected to the middle of the outer side of the drive rods 8. The drive gear 9 meshes with the outer side of the gear ring 7. A bidirectional screw 14 is rotatably connected to the bottom of the fixed platform 2, and two shifting seats 4 are threaded to the two ends of the outer side of the bidirectional screw 14. A second motor is fixedly connected to the bottom of the fixed platform 2, and its output end is fixedly connected to the bidirectional screw 14. A third motor is fixedly connected to one side of the fixed seat 5, and a side gear is fixedly connected to its output end. The side gear meshes with the gear ring 7. There are three drive rods 8, which are annularly distributed on the outer side of the gear ring 7. The drive gear 9 is located on the outer side of the annular groove 6.

[0025] The second motor drives the bidirectional screw 14, causing the two sliding seats 4 to slide in the sliding groove 3, thereby adjusting the distance between the fixed seats 5 to accommodate planetary gear shafts of different lengths. Then, the gear shaft is placed into the fixed seat 5, so that both ends are located inside the two fixed seats 5. The third motor on both sides drives the side gear to rotate, causing the gear ring 7 to rotate, and driving the outer drive gear 9 and drive rod 8 to rotate synchronously.

[0026] Please see Figures 1-4 The drive rod 8 has opposite threads at both ends on its outer side. Internal threaded blocks 10 are threaded to both ends of the drive rod 8. Rotating rods 11 are rotatably connected to the bottom of each of the two internal threaded blocks 10. The same clamping block 12 is rotatably connected to the other end of each of the two rotating rods 11. A lead screw 15 is rotatably connected to the top of the worktable 1. Mating blocks 16 are fixedly connected to both ends of the fixed platform 2 near the lead screw 15. Both mating blocks 16 are threaded to the outer side of the lead screw 15. A punching seat 17 is fixedly connected to the middle of the top of the worktable 1. The top of the punching seat 17... A cylinder is fixedly connected to the end of the workbench 1, and a punch is fixedly connected to the bottom of the cylinder. Support legs are fixedly connected to all four sides of the bottom of the workbench 1. The fixed platform 2 includes bottom blocks 13 at both ends of the bottom. A side rod is fixedly connected to the top of the workbench 1 away from the lead screw 15. The end of the fixed platform 2 away from the lead screw 15 is slidably connected to the outside of the side rod. A No. 1 motor is fixedly connected to the top of the workbench 1, and its output end is fixedly connected to the lead screw 15. There are three clamping blocks 12, which are distributed in a ring on the inner side of the top of the fixed base 5. A soft pad is fixedly connected to the inner side of the clamping blocks 12.

[0027] The two internal screw blocks 10 move along the drive rod 8, thereby driving the clamping block 12 to move towards the center through the rotating rod 11, clamping the planetary gear shaft. Then, the cylinder drives the punch to descend and punch holes. The first motor can drive the lead screw 15 to rotate, and the mating block 16 drives the fixed table 2 and the gear shaft to move, punching holes in different parts of the gear shaft.

[0028] When the gear ring 7 rotates, the drive gear 9 ensures that all drive rods 8 rotate synchronously. This feature greatly improves the operating efficiency and stability of the device. When the drive rod 8 rotates, the inner screw blocks 10 on both sides can move relative to each other along the thread direction. The movement of the inner screw blocks 10 is transmitted through the rotating rod 11, which further drives the clamping blocks 12 to move inward or outward. This displacement method is not only precise and controllable, but can also be flexibly adjusted according to the size of the planetary gear shaft, thereby achieving stable clamping of both ends of gear shafts of different sizes. The clamping blocks 12 are distributed in a ring on the inner side of the top of the fixed seat 5 to ensure all-round clamping of the gear shaft. This not only improves the applicability and flexibility of the device, but also significantly reduces the difficulty and cost of operation.

[0029] By rotating the bidirectional screw 14, the two moving seats 4 can be driven to move synchronously inward or outward, thereby adjusting the distance between the fixed seats 5. This design not only simplifies the operation process, but also ensures precise control of the distance between the fixed seats 5, making it easy to firmly clamp gear shafts of different lengths. The rotation of the lead screw 15 can drive the fixed table 2 and the gear shaft fixed on it to move along a predetermined direction, thereby realizing the movement of the gear shaft in the fixed state. This process is not only simple and fast, but also greatly improves work efficiency and processing accuracy.

[0030] The working principle and usage process of this utility model are as follows: The second motor drives the bidirectional screw 14, causing the two shift seats 4 to slide in the shift groove 3, thereby adjusting the distance between the fixed seats 5 to accommodate planetary gear shafts of different lengths. Then, the gear shaft is placed in the fixed seat 5, with both ends located inside the two fixed seats 5. The third motor on both sides drives the side gear to rotate, causing the gear ring 7 to rotate, and driving the outer drive gear 9 and drive rod 8 to rotate synchronously, causing the two inner screw blocks 10 to move along the drive rod 8. This drives the clamping block 12 to move towards the center through the rotating rod 11, clamping the planetary gear shaft. Then, the cylinder drives the punch to descend and punch holes. The first motor drives the lead screw 15 to rotate, and the mating block 16 drives the fixed table 2 and gear shaft to move, punching holes in different parts of the gear shaft.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
