[0038] Research has revealed the following drawbacks of existing technologies: During the production and processing of motor shafts, in order to ensure the rust prevention and lubrication performance of the product surface, it is usually necessary to apply oil to the surface of the shaft after processing; subsequently, the oiled motor shaft is placed into a box by a conveyor and a robotic arm to complete the integrated packaging.

During subsequent gripping processes, the contaminated robot arm may transfer impurities to the surface of the motor shaft, causing secondary pollution. In some cases, the friction of particulate matter may even cause scratches on the shaft surface, affecting the product's appearance and precision.
[0040] Therefore, how to avoid secondary contamination of the motor shaft is a technical problem that urgently needs to be solved in this field.
[0041] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0043] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0044] like Figures 1 to 4As shown, some embodiments provide a processing equipment for motor shafts, including: a conveying device 1, on one side of which a three-dimensional sliding pair 2 is provided; the conveying device 1 is used to convey the motor shaft 4 to be processed, and a three-dimensional sliding pair 2 (such as an XYZ three-axis linear module or a robotic arm structure) is installed on one side of it; the three-dimensional sliding pair 2 can realize the precise positioning of the gripping component 3 in space, ensuring the gripping, handling and placement accuracy of the motor shaft 4, and adopting a linear module or robotic arm structure, the motion trajectory is controllable, adapting to the processing requirements of motor shafts of different specifications.
[0045] The gripping assembly 3, mounted on the three-dimensional sliding joint 2, is used to grip the motor shaft 4. The overall structure of the gripping assembly 3 is described in detail below. Driven by the three-dimensional sliding joint 2, the gripping assembly 3 includes a rectangular frame 31, a bidirectional cylinder 32, a slider 33, a clamping element 34, a scraper 35, a rack 36, and a gear 37. The rectangular frame 31 provides rigid support, and the bidirectional cylinder 32 drives the slider 33 to move synchronously, ensuring the symmetry and stability of the gripping action. Through the meshing transmission of the gear 37 and the rack 36, the clamping element 34 rotates synchronously during movement, achieving a dynamic cleaning function. Furthermore, the bidirectional cylinder 32 is fixed at the center of the rectangular frame 31, and its piston rod is connected to the two sliders 33, driving the sliders 33 to slide along the rectangular frame 31. The synchronous push-pull action of the bidirectional cylinder 32 ensures that the two clamping elements 34 clamp or release the motor shaft 4 synchronously, avoiding offset or damage caused by uneven force on one side. Using a servo cylinder or electric cylinder allows for precise control of the clamping force, preventing overload damage to the motor shaft surface.
[0046] Specifically, the clamping component 3 includes a rectangular frame 31, with a bidirectional cylinder 32 fixed at the center of the rectangular frame 31; a pair of sliders 33 are slidably arranged on the rectangular frame 31, and the two sliders 33 can move towards each other or away from each other under the drive of the bidirectional cylinder 32, and a clamping member 34 is rotatably connected to the sliders 33.
[0047] The slider 33 is provided with a scraper 35 that abuts against the clamping member 34; a rack 36 is provided on one inner side of the rectangular frame 31, and a gear 37 adapted to the rack 36 is provided on the top of the clamping member 34; when the bidirectional cylinder 32 drives the slider 33 to move, the gear 37 rolls along the rack 36, driving the clamping member 34 to rotate, so as to clean the surface of the clamping member 34 by the scraper 35.
[0048] The scraper 35 is made of silicone and has a triangular cross-section, with the pointed corner 351 abutting against the surface of the clamping part 34. The scraper 35 is made of silicone and has a triangular cross-section, with the pointed corner 351 closely attached to the surface of the rubber cylinder 342. The silicone material has both hardness and elasticity, and the pointed corner design can concentrate the cleaning force, effectively scraping away grease without damaging the rubber cylinder 342. The scraper 35 and the rotating rubber cylinder 342 form a self-cleaning cycle, eliminating the need for machine downtime maintenance and improving production efficiency.
[0049] The clamping member 34 includes a rotating shaft 341 and a rubber cylinder 342. The rubber cylinder 342 wraps around the surface of the rotating shaft 341, and the portion of the rubber cylinder 342 facing the direction of the bidirectional cylinder 32 extends to the outside of the slider 33, suitable for clamping the motor shaft 4. The remaining portion faces the scraper 35 and abuts against the sharp corner 351. The top of the rotating shaft 341 extends above the slider 33 and is fixedly connected to the gear 37. The surface of the rubber cylinder 342 is provided with annular protrusions (not shown in the figure). The annular protrusions are integrally arranged at equal intervals along the height direction of the rubber cylinder 342 to prevent slippage.
[0050] In other words, the clamping member 34 consists of a rotating shaft 341 and a rubber cylinder 342. The rubber cylinder 342 wraps around the rotating shaft 341, with part of it extending out of the slider 33 to clamp the motor shaft 4, and the other part contacting the scraper 35. A gear 37 is fixed at the top of the rotating shaft 341 and meshes with the rack 36 on the rectangular frame 31. When the slider 33 moves, the gear 37 rolls along the rack 36, forcing the clamping member 34 to rotate, so that the surface of the rubber cylinder 342 continuously rubs against the sharp corner 351 of the scraper 35 to remove residual grease. The flexible material of the rubber cylinder 342 can avoid scratching the motor shaft 4, and at the same time, the annular protrusions on its surface enhance the clamping friction and prevent slippage.
[0051] The three-dimensional locating joint 2 is an XYZ three-axis linear module or a robotic arm structure to achieve precise gripping and placement of the motor axis 4. It should be added that the three-dimensional locating joint 2 can be an XYZ linear module (high precision) or a robotic arm (flexible multi-angle operation). The linear module controls the displacement of each axis through servo motors, with high repeatability and positioning accuracy, and is suitable for mass production. The robotic arm is suitable for complex placement paths, such as multi-layer stacking or irregularly shaped packaging.
[0052] Some embodiments provide a machining device for a motor shaft, including: a clamping assembly 3 for gripping a motor shaft 4; the clamping assembly 3 includes a rectangular frame 31, with a bidirectional cylinder 32 fixed at the center of the rectangular frame 31; a pair of sliders 33 are slidably disposed on the rectangular frame 31, the two sliders 33 can move towards each other or away from each other under the drive of the bidirectional cylinder 32, a clamping member 34 is rotatably connected to the sliders 33, and a scraper 35 is disposed on the sliders 33 that abuts against the clamping member 34, the scraper 35 is made of silicone, its cross-section is triangular, and the pointed corner 351 abuts against the surface of the clamping member 34; a rack 36 is disposed on one inner side of the rectangular frame 31, and a gear 37 adapted to the rack 36 is disposed on the top of the clamping member 34; when the bidirectional cylinder 32 drives the sliders 33 to move, the gear 37 rolls along the rack 36, driving the clamping member 34 to rotate, so as to clean the surface of the clamping member 34 by the scraper 35.
[0053] The clamping member 34 includes a rotating shaft 341 and a rubber cylinder 342. The rubber cylinder 342 is wrapped around the surface of the rotating shaft 341, and the portion of the rubber cylinder 342 facing the direction of the bidirectional cylinder 32 extends to the outside of the slider 33, which is suitable for clamping the motor shaft 4. The remaining portion faces the scraper 35 and abuts against the sharp corner 351. The surface of the rubber cylinder 342 is provided with annular protrusions.
[0054] The gripping component 3 is fixed on the three-dimensional sliding joint 2, and a conveying device 1 is arranged below the three-dimensional sliding joint 2. The gripping component 3 is suitable for picking up the motor shaft 4 from the conveying device 1 via the three-dimensional sliding joint 2. The three-dimensional sliding joint 2 is an XYZ three-axis linear module or robotic arm structure to achieve precise gripping and placement of the motor shaft 4. In summary, through the transmission of gear 37 and rack 36 and the cooperation of scraper 35, real-time cleaning of the gripping component 34 is achieved, preventing secondary damage caused by grease contamination. The combination of rubber cylinder 342 and silicone scraper 35 ensures cleaning effectiveness while avoiding rigid contact that could scratch the motor shaft. The coordinated control of the three-dimensional sliding joint 2 and the bidirectional cylinder 32 enables fully unmanned operation, reducing labor costs.
