[0002] Planetary gear shafts are core components of various high-precision transmission equipment. Their structural precision, welding quality, and coaxiality directly determine the operational accuracy, stability, and service life of the transmission system. They are widely used in high-end manufacturing fields such as automotive transmissions, hydraulic systems for construction machinery, transmission mechanisms for new energy equipment, and precision transmission devices for aerospace, making them indispensable core components in modern high-end manufacturing. In the machining process of planetary gear shafts, the welding of gears and shafts is a crucial step. The gears and shafts must first be independently machined, and then precisely assembled and welded to ensure the final product's performance and structural integrity.

[0003] However, existing processing equipment has obvious shortcomings. It often uses multiple power sources to drive each component to operate independently, which can easily lead to asynchronous operation, resulting in misalignment of gears and shafts. In addition, it lacks an effective single-material separation structure, which can easily cause problems such as material stacking and jamming, making it difficult to adapt to batch continuous processing.

In summary, this invention, through innovative mechanical design and automation technology, achieves efficient, flexible, and automated operation of gear shaft welding. It has advantages such as high adaptability, high efficiency and stability, reduced costs, easy maintenance, and improved welding quality, and is suitable for various industries and customized production needs.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention first uses a feeding component to continuously store gear workpieces and push them laterally with the push component, thus feeding the gear workpieces step by step to the welding station. This avoids the tedious manual feeding of each workpiece individually. At the same time, the push component and the adjustment component work together to separate the gear workpieces to be processed individually, effectively avoiding jamming and misalignment caused by multiple workpieces being fed out simultaneously. Furthermore, the push component and the feeding component work together to synchronously lift and feed the shaft workpieces, achieving automatic coaxial alignment of the shaft workpiece and the gear workpiece. It also completes the support and limiting of the bottom of the shaft workpiece, ensuring the stability of the workpiece during welding. The whole process eliminates the need for manual step-by-step feeding and repeated alignment and clamping, greatly reducing manual intervention and effectively eliminating the cumulative error caused by manual alignment. This significantly improves the continuity, production efficiency, and batch consistency of planetary gear shaft welding.

[0017] 2. This invention achieves synchronous operation of the pushing component, adjusting component, and feeding component three through the synchronous output of the bidirectional shaft motor. During the process of pushing the gear workpiece laterally by the pushing block two, it can simultaneously drive the movable block one to cooperate with the stop block. With the meshing transmission of the rack and pinion and the gear one, the synchronous action of the stop blocks on both sides is achieved, pushing the gear workpiece backward, realizing the precise separation of single material, effectively avoiding the faults of multiple workpieces stacking, jamming, and misalignment, and ensuring that the gear workpiece is accurately pushed to the welding station at the upper end of the through slot in a single batch. At the same time, the lower output end of the bidirectional shaft motor can synchronously drive the belt transmission mechanism to intermittently mesh with the half gear, driving the lifting frame to complete the synchronous lifting and feeding of the shaft workpiece, realizing the automatic coaxial alignment of the shaft workpiece and the gear workpiece. It can also link the eccentric wheel to drive the base plate to synchronously insert into the lower end of the shaft workpiece to complete the bottom support limit, ensuring the coaxiality and structural stability of the workpiece during the welding process. The whole invention realizes the continuous automatic feeding of gear workpieces and shaft workpieces, eliminating the need for manual feeding of each piece and repeated alignment and clamping, effectively improving the production efficiency and batch consistency of planetary gear shaft welding processing, and adapting to the batch continuous processing needs of workpieces.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1: A machining apparatus for planetary gear shafts, see [reference] Figure 1 The T-shaped processing table 1 includes a feeding component 2 at the upper end of the T-shaped processing table 1, a through groove 11 on the left side of the front end of the T-shaped processing table 1, a support leg 12 fixedly connected to the lower end of the T-shaped processing table 1, a pushing component 3 at the front end of the feeding component 2, an adjusting component 4 at the connection between the feeding component 2 and the pushing component 3, a feeding component 5 at the lower end of the T-shaped processing table 1, and a welding component 6 at the front end of the T-shaped processing table 1. The welding component 6 includes a processing seat 61 and a welding device body 62.

[0022] The welding device body 62 mentioned above is a semi-automatic arc welding arm in the prior art. It uses a multi-degree-of-freedom robotic arm as the execution carrier, and is equipped with an arc welding power source, wire feeding device, protective gas circuit and CNC control system to complete the automated process of arc welding. Its core working principle is: before the operation, through teaching programming or offline programming, process parameters such as weld trajectory, welding current, voltage, welding speed, wire feeding rate and other process parameters are entered into the control system to establish the welding path and specifications.

[0023] During operation, after the system starts, the welding power source establishes a stable arc between the welding wire and the workpiece. The high temperature generated by the arc simultaneously melts the base material and the continuously fed filler wire, forming a molten pool. The robotic arm moves the welding torch at a constant speed along a preset trajectory, coordinating with the wire feeding mechanism to continuously and stably feed the wire. As the welding torch moves forward, the molten pool gradually cools and crystallizes, forming a continuous and dense weld. Shielding gas is simultaneously ejected from the welding torch nozzle, isolating the molten pool from air and preventing defects such as oxidation and porosity.

[0024] In semi-automatic mode, operators can assist in adjusting the workpiece posture and intervene in the welding process; the control system provides real-time feedback to adjust the arc parameters and movement speed, ensuring stable arc combustion and uniform molten pool formation, ultimately achieving high-precision and high-efficiency continuous welding, and significantly improving weld consistency and production stability.

[0025] Furthermore, the through groove 11 is used for feeding shaft workpieces.

[0026] This invention first uses the feeding component 2 to continuously store gear workpieces and then pushes them laterally with the push component 3, thus feeding the gear workpieces step by step to the welding station. This avoids the tedious manual feeding of each workpiece individually. Simultaneously, the push component 3 and the adjustment component 4 work together to separate individual gear workpieces, effectively avoiding jamming and misalignment caused by simultaneous feeding of multiple workpieces. Furthermore, the push component 3 and the feeding component 5 work together to synchronously lift and feed shaft workpieces, achieving automatic coaxial alignment of the shaft workpiece and the gear workpiece, and providing support and limiting at the bottom of the shaft workpiece to ensure the stability of the workpiece during welding. The entire device eliminates the need for manual step-by-step feeding and repeated alignment and clamping, significantly reducing manual intervention and effectively eliminating the cumulative errors caused by manual alignment. This significantly improves the continuity, production efficiency, and batch consistency of planetary gear shaft welding.

[0027] Example 2, see Figure 1 and Figure 10The feeding assembly 2 includes a feeding box 21 fixedly connected to the upper end of the T-shaped processing table 1. Fixing blocks 22 are fixedly connected to both sides of the front end of the feeding box 21. Springs 23 are fixedly connected to the rear ends of the two fixing blocks 22. Sliding blocks 24 are fixedly connected to the rear ends of the two springs 23. Sliding rods 25 are fixedly connected to the front end of the sliding blocks 24. Pushing blocks 26 are fixedly connected to the front end of the sliding rods 25. The outer surface of the pushing blocks 26 is slidably connected to the feeding box 21.

[0028] Specifically, multiple gear workpieces are placed side by side in the loading box 21. The sliding block 24, sliding rod 25 and pushing block 26 will always be pushed forward by the tension of the spring 23, so that the gear workpiece at the rear end abuts against the front end of the pushing block 26, and the gear workpiece at the front end abuts against the rear end of the baffle 38 located on the front side. The gear workpiece located at the top of the T-shaped processing table 1 and in contact with the baffle 38 is the workpiece to be processed, waiting for the pushing block 36 to push it to the top of the through groove 11.

[0029] Furthermore, the pushing component 3 includes a bidirectional shaft motor 31 fixedly installed inside the T-shaped processing table 1. A rotating arm 32 is fixedly connected to the output end of the bidirectional shaft motor 31. A sliding column 33 is rotatably connected to the upper end of the rotating arm 32. A limit ring 34 is slidably connected to the outer surface of the sliding column 33. A connecting block 35 is fixedly connected to the left side of the limit ring 34. The lower end of the connecting block 35 is slidably connected to the T-shaped processing table 1. A second pushing block 36 is fixedly connected to the left side of the connecting block 35. A first baffle 37 is fixedly connected to the rear end of the second pushing block 36. Two second baffles 38 are fixedly connected to the upper end of the T-shaped processing table 1.

[0030] Furthermore, the bidirectional shaft motor 31 mentioned above is existing technology, and the direction of rotation and speed of the two output ends are the same.

[0031] The bidirectional shaft motor 31 is started to drive the rotating arm 32 to rotate clockwise. During the rotation, the rotating arm 32 will drive the sliding column 33 to slide up and down on the inner surface of the limiting ring 34. The connecting block 35 is provided with a locking block at the contact position with the T-shaped processing table 1, so that it can only move horizontally on the surface of the T-shaped processing table 1 under the drive of the limiting ring 34.

[0032] The stroke of the push block 36 to the left is just enough to push the gear to the top of the through slot 11 for machining.

[0033] See Figure 1 - Figure 7The adjusting component 4 includes sliding grooves 41 on both sides of the front end of the feeding box 21, springs 44 fixedly connected to the front ends of two fixed blocks 22, stops 43 slidably connected to the front ends of two springs 44, guide block 432 fixedly connected to the front end of the right stop 43, two stops 43 slidably connected to the inner surface of the sliding groove 41 on the same side, sliding grooves 431 on the rear ends of two stops 43, sliding grooves 431 on the rear ends of two stops 43, sliding grooves 45 on the rear ends of baffle 37, springs 46 fixedly connected to the inner surface of sliding groove 45, movable block 47 fixedly connected to the left end of spring 46, the outer surface of movable block 47 slidably connected to sliding groove 45, and the front end of guide block 432 slidably connected to baffle 37.

[0034] Furthermore, the front end of the feeding box 21 has an internal slot 48, and the lower ends of the two stops 43 are fixedly connected to racks 49. The two sides of the feeding box 21, located below the two sliding slots 41, have sliding slots 410. The outer surfaces of the two racks 49 are slidably connected to the sliding slots 410 on the same side. The internal slot 48 has a fixed limit seat 411. The upper end of the limit seat 411 is slidably connected to a sliding seat 412. The upper end of the sliding seat 412 is fixedly connected to two limit seats 413. The upper end of the sliding seat 412 is rotatably connected to a gear 414. The ends of the two racks 49 that are close to each other are meshed with the gear 414. The lower ends of the two racks 49 are slidably connected to the limit seats 413 on the same side.

[0035] Furthermore, the two limiting seats 413 mentioned above are for limiting the two racks 49, so that the two racks 49 can slide laterally or move together with the sliding seat 412 when moving vertically, so that the two racks 49 are always in mesh with the gear 414 no matter how they move. The sliding groove 410 is for facilitating the movement of the racks 49.

[0036] The front end of the guide block 432 is wedge-shaped, with the left side higher and the right side lower. When the baffle 37 moves to the left, it will push the guide block 432 backward.

[0037] The specific operation process of the pushing component 3 and the adjusting component 4 is as follows: the bidirectional shaft motor 31 is started to drive the rotating arm 32 to rotate, driving the limiting ring 34, connecting block 35, pushing block 2 36 and baffle 1 37 to move to the left. During the movement, the movable block 1 47 is driven by the baffle 1 37 to first contact the stop block 43, so that the stop block 43 drives the guide block 432 to move towards the upper material box 1 21. When the left end of the guide block 432 abuts against the edge of the upper material box 1 21, the stop block 43 has moved to the front side of the gear workpiece placed at the front end of the upper material box 1 21. Simultaneously, when the right stop block 43 is pushed to move towards the upper material box 1 21, it will drive the rack 49 on the same side to slide on the surface of the limiting seat 2 413, thereby meshing with the gear 1 414. When the gear 1 414 rotates, it will also drive the left rack 49 and the stop block 43 to move towards the upper material box 1 21, so that the ends of the two stop blocks 43 that are close to each other move to the front side of the gear workpiece.

[0038] Furthermore, as the baffle 37 continues to move, the movable block 47 will remain stationary. When the left end of the baffle 37 slides on the surface of the guide block 432, the front end of the guide block 432 will be squeezed, causing the baffle 43, rack 49, sliding seat 412 and other structures to move backward synchronously. Simultaneously, the baffle 43 on the other side will also move together, thereby pushing the gear workpiece backward a part, so that the gear workpiece is separated from the gear workpiece that has already been separated from the loading box 21, making it easier for the gear workpiece on the T-shaped processing table 1 to be smoothly pushed to the upper end of the through groove 11 by the push block 36.

[0039] Simultaneously, while the baffle 37 is still moving to the left, the guide block 432 is blocked by the loading box 21 and cannot move. Therefore, the movable block 47 will squeeze the spring 46. When the push block 36 pushes the gear workpiece to the top of the through slot 11, the movable block 47 is located on the right side of the baffle 37.

[0040] See Figure 7 - Figure 10 The feeding assembly 3 5 includes a housing 51 fixedly connected to the lower end of the T-shaped processing table 1, a rotating shaft 52 fixedly connected to the output end of the bidirectional shaft motor 31, a belt drive mechanism 53 fixedly connected to the outer surface of the rotating shaft 52, a rotating shaft 54 ​​fixedly connected to the end of the belt drive mechanism 53 away from the rotating shaft 52, a half gear 55 fixedly connected to the outer surface of the rotating shaft 54, a gear 56 meshing with the outer surface of the half gear 55, a reciprocating rod 57 fixedly connected to the inner surface of the gear 56, a reciprocating block 58 slidably connected to the outer surface of the reciprocating rod 57, and a lifting frame 59 fixedly connected to the left side of the reciprocating block 58.

[0041] The belt drive mechanism 53 described above consists of two pulleys and a belt.

[0042] Furthermore, the reciprocating rod 57 and the reciprocating block 58 are based on the existing ball screw structure. When the reciprocating rod 57 rotates in one direction, the reciprocating block 58 can reciprocate up and down on the surface of the reciprocating rod 57.

[0043] Half gear 55 and gear 2 56 are intermittently meshing.

[0044] Furthermore, a loading box 2 510 is fixedly connected to the lower end of the T-shaped processing table 1 and to the lower side of the through groove 11. A sliding groove 511 is opened at the right end of the loading box 2 510, and a sliding groove 6 512 is opened at the right end of the loading box 2 510 and to the upper end of the sliding groove 511. An eccentric wheel 513 is fixedly connected to the outer surface of the rotating shaft 1 52 and to the upper end of the belt drive mechanism 53. A sliding groove 7 514 is opened at the lower end of the T-shaped processing table 1. A spring 515 is fixedly connected to the inner surface of the sliding groove 7 514. A push block 3 516 is fixedly connected to the right end of the spring 515. The outer surface of the push block 3 516 is slidably connected to the sliding groove 7 514, and the outer surface of the eccentric wheel 513 is movably connected to the push block 3 516.

[0045] The second loading box 510 is used to store the shaft workpieces for processing. Each shaft workpiece is stacked vertically on the inner wall of the second loading box 510.

[0046] Furthermore, spring 515 allows sliding groove 7 514 to reset after it is no longer compressed, thereby facilitating the reciprocating movement of base plate 520.

[0047] Furthermore, a push rod 517 is fixedly connected to the left end of the push block 3 516, and two limit posts 518 are fixedly connected to the upper right side of the loading box 2 510. The outer surfaces of the two limit posts 518 are slidably connected to the movable block 2 519. The left end of the movable block 2 519 is fixedly connected to the base plate 520, and the left end of the push rod 517 is fixedly connected to the base plate 520.

[0048] Furthermore, the outer surface of the base plate 520 is slidably connected to the sliding groove 512, and the outer surface of the lifting frame 59 is slidably connected to the sliding groove 511.

[0049] Specifically, when the rotating arm 32 rotates clockwise from the leftmost end to the rightmost end, the second pushing block 36 also retracts from the leftmost end to the rightmost end. When the second pushing block 36 moves completely to the right side of the first loading box 21, the front end of the first loading box 21 is no longer blocked. The gear workpiece at the front end of the first loading box 21 is disengaged from the first loading box 21 under the push of the first pushing block 26 and comes into contact with the second baffle 38 located on the front side. The gear workpiece abuts against the gear workpiece on the first loading box 21.

[0050] Synchronously, as the push block 36 moves from left to right, the rotation of the rotating shaft 52 at the lower end of the bidirectional shaft motor 31 drives the belt drive mechanism 53, the rotating shaft 54, and the half gear 55 to rotate. The half gear 55 meshes with the gear 56, thereby driving the reciprocating rod 57 to rotate. This causes the reciprocating block 58 and the lifting frame 59 to move upward as a whole, lifting a shaft workpiece upward and passing through the center of the through slot 11 and the gear workpiece, achieving coaxial alignment between the gear workpiece and the shaft workpiece. When the push block 36 moves to the far right, the rotating shaft 52 drives the eccentric wheel 513 to rotate to a position where the eccentric wheel 513 just abuts against the spring 515. The spring 515 is then pushed to the left, thereby driving the push rod 517, the movable block 519, and the base plate 520 to insert into the sliding groove 6 512, so that the base plate 520 abuts against the lower end of the shaft workpiece to be processed, increasing the stability of the shaft workpiece and the gear workpiece during processing.

[0051] After the base plate 520 is inserted into the loading box 510, the bidirectional shaft motor 31 is turned off, and the welding device body 62 is started to weld the workpiece at the through slot 11. After the welding is completed, the welded planetary gear shaft is manually removed, and the rotating arm 32 is started again to load the gear workpiece and the shaft workpiece respectively.

[0052] It should be noted that when the reciprocating block 58 rises to the top of the reciprocating rod 57, the shaft inside the second loading box 510 and the gear workpiece inside the first loading box 21 have all been processed. At this time, with the first loading box 21 and the second loading box 510 empty, the rotating arm 32 can be allowed to rotate the various structures, so that the reciprocating block 58 returns to the lowest position.

[0053] This invention achieves synchronized operation of the pushing component 3, adjusting component 4, and feeding component 5 through the synchronous output of the bidirectional shaft motor 31 at both ends. During the lateral pushing of the gear workpiece by the pushing block 36, the movable block 47 and the stop block 43 are simultaneously engaged. The meshing transmission between the rack 49 and the gear 414 enables the synchronous movement of the stop blocks 43 on both sides, pushing the gear workpiece backward. This achieves precise separation of a single piece, effectively avoiding the problems of multiple workpieces stacking, jamming, and misalignment. It ensures that the gear workpiece is accurately pushed to the welding station at the upper end of the through slot 11 in a single operation. Simultaneously, the lower output end of the bidirectional shaft motor 31... The synchronous drive belt transmission mechanism 53 and half gear 55 intermittently mesh, driving the lifting frame 59 to complete the synchronous lifting and feeding of the shaft workpiece, realizing the automatic coaxial alignment of the shaft workpiece and the gear workpiece. It can also link the eccentric wheel 513 to drive the base plate 520 to be inserted into the lower end of the shaft workpiece to complete the bottom support limit, ensuring the coaxiality and structural stability of the workpiece during the welding process. The whole system realizes the continuous automatic feeding of gear workpiece and shaft workpiece, eliminating the need for manual feeding and repeated alignment and clamping, effectively improving the production efficiency and batch consistency of planetary gear shaft welding processing, and adapting to the batch continuous processing needs of workpieces.

[0054] It should be noted that the specific installation method, circuit connection method, and control method of the bidirectional shaft motor 31 and the welding device body 62 used in this invention are all conventional designs, and will not be described in detail in this invention.
