Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to an automatic feeding and pressing device for output shafts and gears. Background Technology

[0002] The motor shaft uses multi-stage transmission gears to progressively reduce or increase speed, which can significantly alter the output speed and torque. For example... Figure 1 As shown, in the assembly and production of the motor gearbox, assembling the output shaft workpiece 10 and the gear workpiece 20 onto the motor assembly is a key process. As the power transmission gear workpiece 20, it must be coaxially fixed with the output shaft workpiece 10 on the one hand, and mesh with the multi-stage transmission gear on the other hand.

[0003] In response to the aforementioned working conditions, many production processes still rely on manual feeding and assembly, resulting in low efficiency, high labor intensity, and susceptibility to problems such as inaccurate positioning and inconsistent assembly interference due to human factors, thus affecting the quality of finished products. While some existing automatic pressing mechanisms can complete the pressing process simply, the output shaft workpiece 10 and gear workpiece 20 are small parts, prone to jamming, misalignment, or falling during automatic feeding, still requiring manual assistance for feeding and positioning, and thus failing to meet the requirements of fully automated, high-precision assembly. Utility Model Content

The output end of the output shaft vibratory plate is provided with a first conveying channel, and the output shaft workpieces are output one by one along the first conveying channel. An air-blowing distributor is provided at the end of the first conveying channel, and the output port of the air-blowing distributor is connected to a bird's beak through an air pipe.

The gear workpieces are output one by one along the second conveying channel. A stop block is provided at the end of the second conveying channel.

[0018] The lifting assembly is located below the stop block and is used to lift a single gear workpiece located in the stop block to a set height;

[0019] The gear gripping assembly is used to grip the gear workpiece from a set height and place it in the gear positioning seat.

[0020] As an optional solution, the gear gripping assembly includes a rotary drive module, a lifting drive module, and grippers.

"Below," "below," and "under" the second feature include the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] against Figure 1 Automated assembly conditions, such as Figures 2 to 4As shown, this utility model provides an automatic feeding and pressing device for output shafts and gears, including a gear feeding mechanism 1, a guide positioning mechanism 2, an output shaft feeding mechanism 3, and a pressing mechanism 4. The gear feeding mechanism 1 is used to transfer several gear workpieces 20 one by one to a gear positioning seat 5, with the shaft holes of the gear workpieces 20 in the gear positioning seat 5 arranged vertically. The guide positioning mechanism 2 includes a beak 21 that can reciprocate between a first position and a second position. The beak 21 in the first position is located on one side of the gear positioning seat 5, and the beak 21 in the second position is located directly above the gear positioning seat 5. The output shaft feeding mechanism 3 is used to transfer several output shaft workpieces 10 one by one into the beak 21 in the first position, with guide holes in the beak 21 for guiding the vertical output of the output shaft workpieces 10. The pressing mechanism 4 is used to apply pressure to the output shaft workpieces 10 in the beak 21 in the second position, so that the output shaft workpieces 10 and gear workpieces 20 are assembled in place.

[0040] This achieves full automation of the output shaft workpiece 10 and gear workpiece 20 from automatic feeding and precise positioning to automatic pressing, effectively avoiding problems such as inaccurate positioning and inconsistent interference fit caused by manual operation. In particular, the beak 21 receives the output shaft workpiece 10 in the first position, and after moving to the second position, its guide hole can ensure that the shaft holes of the output shaft workpiece 10 and gear workpiece 20 are accurately aligned, which greatly improves the coaxiality of the assembly and the pressing quality, while significantly reducing labor intensity and improving production efficiency.

[0041] In at least one embodiment, a transfer seat 22 is provided on one side of the gear positioning seat 5, which can approach and move away from the gear positioning seat 5. A lifting seat 23 that can move vertically is provided on the transfer seat 22, and the beak 21 is installed on the lifting seat 23.

[0042] The transfer seat 22 and lifting seat 23 enable precise horizontal and vertical displacement of the beak 21, allowing the output shaft workpiece 10 to be smoothly transferred from one side of the gear positioning seat 5 to directly above it, preparing for subsequent vertical pressing and avoiding the risk of interference and collision that may arise from complex trajectories. Specifically, the movement of the transfer seat 22 and lifting seat 23 can be achieved using a cylinder and guide rail, which will not be further described here.

[0043] Based on this, the pressing mechanism 4 includes a pressing cylinder 41 disposed on the lifting seat 23 and located above the beak 21. An elastic top pin 42 is provided on the output rod of the pressing cylinder 41. The elastic top pin 42 is used to press the output shaft workpiece 10 in the beak 21 downward.

[0044] The elastic top pin 42 can convert the rigid thrust of the press-fit cylinder 41 into a flexible pressure with a small amplitude, and can adaptively compensate for the slight coaxiality deviation that may exist after alignment, preventing damage to the shaft hole of the precision output shaft workpiece 10 or gear workpiece 20 due to rigid impact. In addition, the press-fit mechanism 4 and the beak 21 are fixed together on the lifting seat 23, which can always ensure that the elastic top pin 42 and the output shaft workpiece 10 output by the beak 21 are aligned, without the need for further positioning.

[0045] Furthermore, the travel of the transfer seat 22, the travel of the lifting seat 23, and the pressing travel of the elastic top pin 42 are detected by corresponding displacement sensors to ensure repeatability of displacement accuracy and press-fit consistency, thereby improving assembly quality.

[0046] In at least one embodiment, the output shaft feeding mechanism 3 includes an output shaft vibratory plate 31, which holds a plurality of output shaft workpieces 10. The output end of the output shaft vibratory plate 31 is provided with a first conveying channel 32, and the output shaft workpieces 10 are output one by one along the first conveying channel 32. The end of the first conveying channel 32 is provided with an air-blowing distributor 33, and the output port of the air-blowing distributor 33 is connected to the beak 21 through an air pipe.

[0047] The output shaft vibratory plate 31 enables the accurate output of each workpiece 10 in a specific posture. The air-blowing feeder 33 avoids problems such as jamming, scratching, and inaccurate clamping that may be caused by the gripper method. It is particularly suitable for processing small shaft parts, ensuring smooth and stable feeding. The air-blowing feeder 33 is existing technology and will not be described in detail here.

[0048] Furthermore, a linear vibrator 34 is provided below the first conveying channel 32. The linear vibrator 34 is used to promote the feeding of the output shaft workpiece 10 along the first conveying channel 32, ensuring that the output shaft workpiece 10 is conveyed smoothly, continuously, and one by one in the first conveying channel 32, preventing jamming or accumulation, and ensuring the stability and reliability of the feeding process of the output shaft workpiece 10.

[0049] In at least one embodiment, the gear feeding mechanism 1 includes a gear vibratory feeder 11, a lifting assembly, and a gear gripping assembly. The gear vibratory feeder 11 holds a plurality of gear workpieces 20. A second conveying channel 12 is provided at the output end of the gear vibratory feeder 11. The gear workpieces 20 are output one by one along the second conveying channel 12. A stop block 13 is provided at the end of the second conveying channel 12. The lifting assembly is located below the stop block 13 and is used to lift a single gear workpiece 20 located in the stop block 13 to a set height. The gear gripping assembly is used to grip the gear workpiece 20 from the set height and place it in the gear positioning seat 5.

[0050] The gear vibratory feeder 11 can realize the automatic sorting and directional conveying of a large number of gear workpieces 20, improving the feeding efficiency and automation level; the lifting component steadily lifts the horizontally conveyed gear workpieces 20 one by one to the set height, so that the gear gripping component can grip them; the gear gripping component realizes the flow of the gear workpieces 20 from the set height to the gear positioning seat 5.

[0051] Furthermore, the gear gripping assembly includes a rotary drive module 14, a lifting drive module 15, and a gripper 16. The rotary drive module 14 is disposed between the stop block 13 and the gear positioning seat 5. The lifting drive module 15 is installed at the output end of the rotary drive module 14, and the gripper 16 is installed at the output end of the lifting drive module 15. The gripper 16 is used to grip or release the gear workpiece 20.

[0052] The coordinated action of the rotary drive module 14 and the lifting drive module 15 can be achieved through a combination structure of a rotary motor and a vertical output cylinder, which meets the transfer requirements of the gear workpiece 20.

[0053] Furthermore, the lifting assembly includes a lifting cylinder 17, the output rod of the lifting cylinder 17 extends toward the stop block 13, and the end of the output rod of the lifting cylinder 17 is provided with a positioning block 18 for supporting and positioning the gear workpiece 20.

[0054] The gear workpiece 20 can be gently lifted by the positioning block 18 on the output rod driven by the lifting cylinder 17. The design of the positioning block 18 can ensure that the gear workpiece 20 maintains the correct posture and center position during the lifting process, preventing it from tipping over or shifting, thus laying a good foundation for subsequent gripping and assembly.

[0055] In summary, this automatic feeding and pressing device for the output shaft and gears constructs a highly efficient and precise automated assembly unit through the coordinated action of multiple mechanisms. Among them, the air-blowing material distribution method enables the orderly feeding of the output shaft workpiece 10, the movable beak 21 enables the precise positioning of the output shaft workpiece 10, the lifting and gripping method enables the orderly feeding of the gear workpiece 20, and the flexible pressure applied by the elastic top pin 42 ensures the high coaxiality pressing of the output shaft workpiece 10 and the gear workpiece 20, effectively improving the assembly quality and product consistency, reducing labor costs and operating difficulty, and providing reliable technical support for the design of automated production lines.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
