[0043] against Figure 1Automated assembly conditions, such as Figures 2 to 4 As shown, this utility model provides an automatic feeding and pressing device for motors and gears, including a motor conveying mechanism 1, a gear conveying mechanism 2, a centering and positioning mechanism 3, and a pressing mechanism 4, wherein:

[0044] The motor conveying mechanism 1 is used to neatly arrange several motor workpieces 10 and convey them one by one to the motor placement position 5. The motor placement position 5 is used to hold the motor workpieces 10 and make the output shaft of the motor workpieces 10 face vertically upward.

[0045] The gear conveying mechanism 2 is used to neatly arrange and convey several gear workpieces 20 one by one to the gear receiving position, which is located above the motor placement position 5.

[0046] The centering and positioning mechanism 3 is used to center and align the output shaft of the motor workpiece 10 and the gear workpiece 20 respectively, so that the output shaft of the motor workpiece 10 and the gear workpiece 20 are arranged coaxially, and the gear workpiece 20 is brought close to the shaft end of the output shaft of the motor workpiece 10.

[0047] The pressing mechanism 4 is used to apply vertical pressure to the gear workpiece 20, so that the gear workpiece 20 is pressed into place on the output shaft of the motor workpiece 10.

[0048] Thus, by integrating automated conveying, precise positioning, and intelligent pressing, the automation level of the automated assembly process is comprehensively improved, ensuring the coaxiality of the output shaft of the motor workpiece 10 and the shaft hole of the gear workpiece 20, avoiding subsequent misalignment or damage to the mating surface, reducing manual intervention, significantly improving production efficiency, and ensuring assembly quality and finished product consistency.

[0049] In at least one embodiment, the motor conveying mechanism 1 includes a motor trolley 11 and a motor gripping assembly 12. The motor trolley 11 is placed on one side of the motor placement position 5. The motor trolley 11 is provided with a plurality of arrayed positioning trays 111, which are used to load a single motor workpiece 10. The motor gripping assembly 12 includes a three-axis drive module 121 and a first gripper 122 driven by the three-axis drive module 121. The three-axis drive module 121 is disposed above the motor trolley 11 and the motor placement position 5. The first gripper 122 is used to grip the motor workpiece 10 from the single positioning tray 111 and place it in the motor placement position 5.

[0050] The motor trolley 11 enables batch buffering and loading of motor workpieces 10, and in conjunction with the motor gripping assembly 12, enables the output of motor workpieces 10 one by one. Specifically, the three-axis drive module 121 and the first gripper 122 achieve precise gripping and placement, improving the level of automation and production cycle. The three-axis drive module 121 can adopt existing technology to realize XYZ three-axis transfer function, which will not be described in detail here; the first gripper 122 can be a pneumatic gripper to realize simple gripping and placing functions.

[0051] Furthermore, a positioning frame 13 is provided on one side of the motor placement position 5, the motor cart 11 is placed on the positioning frame 13, and a first sensor is provided on the positioning frame 13 for detecting whether the motor cart 11 is parked in the correct position.

[0052] The position of the motor trolley 11 is located by the first sensor, that is, the position of each positioning tray 111 on the motor trolley 11 is determined, so that the first gripper 122 can accurately grasp each motor workpiece 10, ensuring the continuity and accuracy of the feeding process.

[0053] In at least one embodiment, the gear conveying mechanism 2 includes a gear vibratory plate 21, a lifting assembly 22, and a gear gripping assembly 23. The gear vibratory plate 21 holds a plurality of gear workpieces 20. The output end of the gear vibratory plate 21 is provided with a conveying channel 24. The gear workpieces 20 are output one by one along the conveying channel 24. The end of the conveying channel 24 is provided with a stop block 25. The lifting assembly 22 is located below the stop block 25. The lifting assembly 22 is used to lift a single gear workpiece 20 located at the end of the conveying channel 24 to a set height. The gear gripping assembly 23 includes a rotary drive module 231 and a second gripper 232 driven by the rotary drive module 231. The rotary drive module 231 is located between the stop block 25 and the motor placement position 5. The second gripper 232 is used to grip the gear workpiece 20 from the set height and place it in the gear receiving position.

[0054] The gear vibratory feeder 21 enables batch buffering and feeding of gear workpieces 20. Combined with the lifting assembly 22 and gear gripping assembly 23, it achieves automatic sorting, orientation, and batch feeding of gear workpieces 20, improving automation and production cycle time. The gear vibratory feeder 21 can utilize existing technology and will not be described in detail here. The lifting assembly 22 can be a cylinder to lift the gear workpieces 20. The rotary drive module 231 can be a combination of a rotary motor, a horizontal output cylinder, and a vertical output cylinder to meet the transfer requirements of the gear workpieces 20; this will not be described in detail here. The second gripper 232 can be a pneumatic gripper for simple gripping and releasing functions.

[0055] Furthermore, a linear vibrator 26 is installed below the conveying channel 24. The linear vibrator 26 is used to promote the feeding of the gear workpiece 20 along the conveying channel 24, ensuring that the gear workpiece 20 is conveyed smoothly, continuously and one by one in the conveying channel 24, preventing jamming or accumulation, and ensuring the stability and reliability of the feeding process.

[0056] It should be noted that the pressing direction is vertical. In order to avoid interference between the feeding action of the motor workpiece 10 and the gear workpiece 20 and the subsequent pressing action, a transfer frame 6 is provided on one side of the motor placement position 5. The transfer frame 6 can move closer to and away from the motor placement position 5. The centering positioning mechanism 3 and the pressing mechanism 4 are respectively set on the transfer frame 6 to avoid the motor conveying mechanism 1 and the gear conveying mechanism 2 from feeding the motor placement position 5.

[0057] The transfer frame 6 enables the centering and positioning mechanism 3 and the pressing mechanism 4 to reciprocate relative to the motor placement position 5, thus avoiding the movement of the motor conveying mechanism 1 and the gear conveying mechanism 2, resulting in a more rational structure. Specifically, the movement of the transfer frame 6 can be achieved by a cylinder and guide rail, or by other methods that can ensure movement accuracy.

[0058] In at least one embodiment, the centering positioning mechanism 3 includes a motor positioning component 31 and a gear positioning component 32. The motor positioning component 31 includes a third gripper 311, which is disposed on the transfer frame 6 and can move closer to and away from the motor placement position 5. The third gripper 311 is used to clamp the output shaft of the motor workpiece 10, so that the output shaft of the motor workpiece 10 is in the middle position of the third gripper 311. The gear positioning component 32 includes a lifting seat 321 and a fourth gripper 322, which is disposed on the lifting seat 321. The fourth gripper 322 is used to clamp the gear workpiece 20, so that the gear workpiece 20 is in the middle position of the fourth gripper 322. The lifting seat 321 is used to drive the fourth gripper 322 to switch between the gear receiving position and the shaft end position close to the output shaft of the motor workpiece 10. The middle position of the fourth gripper 322 is vertically aligned with the middle position of the third gripper 311.

[0059] The motor positioning assembly 31 and gear positioning assembly 32 actively position and center the motor workpiece 10 and gear workpiece 20, ensuring high-precision coaxial alignment of the motor shaft and shaft hole before pressing, effectively preventing misalignment, scratches on the motor shaft journal, or damage to the shaft hole. The third gripper 311 and fourth gripper 322 can be pneumatic grippers, providing simple gripping and releasing functions. The lifting seat 321 can be driven by a cylinder and guide rail mounted on the transfer frame 6, primarily facilitating the transfer of the gear workpiece 20 from the gear conveying mechanism 2 to the pre-pressing preparation. Furthermore, considering the movement of the transfer frame 6, at least one of the third gripper 311 and fourth gripper 322 should be able to move closer to and further away from the motor placement position 5, preventing the third gripper 311 or fourth gripper 322 from failing to avoid the motor workpiece 10 or gear workpiece 20 during the movement of the transfer frame 6. Here, the example of the third gripper 311 being able to move forward and backward is provided.

[0060] In at least one embodiment, the pressing mechanism 4 includes a presser 41 and an elastic pin 42. The presser 41 is mounted on the lifting seat 321, and the elastic pin 42 is disposed at the output end of the presser 41. The elastic pin 42 is vertically aligned with the middle position of the fourth gripper 322. The presser 41 is used to drive the elastic pin 42 to press the gear workpiece 20.

[0061] The pressing action is completed by driving the elastic top pin 42 through the presser 41. The presser 41 can be provided with pressing power by a cylinder. The elastic top pin 42 can convert the rigid thrust of the presser 41 into flexible pressure with a small amplitude, which can adaptively compensate for the extremely small coaxiality deviation that may exist after alignment, and protect the motor workpiece 10 and the gear workpiece 20.

[0062] Furthermore, a second sensor 43 is provided on the lifting seat 321 for detecting the downward stroke of the elastic top pin 42.

[0063] The second sensor 43 monitors and provides feedback on the pressing degree in real time to avoid inadequate or excessive pressing and to ensure pressing quality.

[0064] In summary, this automatic feeding and pressing device for motors and gears achieves full automation of the entire process from automatic feeding and precise centering of motor workpiece 10 and gear workpiece 20 to pressing through the coordinated action of multiple mechanisms. It also ensures positioning accuracy and assembly quality, significantly improves production efficiency and product consistency, reduces labor costs and operational difficulty, and provides reliable technical support for the design of automated production lines.

[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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.
