[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1-4 As shown, this utility model discloses a bearing pressing and feeding mechanism, including a support assembly, a pressing assembly, and a transmission assembly. The pressing assembly is located on the inner wall of the support assembly to facilitate the pressing of the bearing. The transmission assembly is located on the inner wall of the support assembly to facilitate the transportation of materials. The pressing assembly includes a servo motor 21, a transmission rod 22, and a pressure plate 23. The servo motor 21 is located on the upper surface of the support assembly, the transmission rod 22 is located at one end of the servo motor 21, and the pressure plate 23 is located at one end of the transmission rod 22 to facilitate the pressing of materials. The inner wall of the pressure plate 23 is provided with a telescopic rod 24. Multiple telescopic rods 24 are provided and spaced apart. One end of the telescopic rod 24 is provided with a limiting sleeve 25 to facilitate the limiting of the telescopic rod 24. One end of the telescopic rod 24 is provided with a horizontal plate 27. The upper surface of the horizontal plate 27 is provided with a limiting block 26, and one end of the horizontal plate 27 is provided with a pressing upper mold 28 corresponding to the limiting block 26.
[0020] The pressing assembly uses a servo motor 21 to drive the transmission rod 22, which, together with multiple sets of spaced telescopic rods 24 and limiting sleeves 25 within the pressing plate 23, forms a dynamic pressing adjustment system. The telescopic rods 24 can adaptively adjust the pressing angle according to the bearing outer ring size. The combination of the horizontal plate 27 and the limiting block 26 further constrains the vertical displacement accuracy of the pressing upper mold 28, ensuring that the coaxiality error between the bearing and the pressing hole is controlled within the micrometer level. This effectively avoids the problem of uneven bearing force and scrapping caused by posture deviations in traditional vibratory feeders or robotic arms.
[0021] Specifically, the servo motor 21 of the press-fit assembly serves as the power source, converting the rotational motion into linear motion through the transmission rod 22, driving the pressure plate 23 to move vertically downward. Multiple telescopic rods 24 provided on the inner side wall of the pressure plate 23 extend synchronously, and the limiting sleeves 25 at their ends cooperate with the horizontal plate 27 to form a support and guide structure for the upper press-fit mold 28; the limiting block 26 on the upper surface of the horizontal plate 27 matches the upper press-fit mold 28 (corresponding to the cavity of the lower press-fit mold 38), further constraining the movement trajectory of the upper press-fit mold 28 and ensuring its coaxiality with the lower press-fit mold 38.
[0022] When the pressure plate 23 descends to the set position, the upper pressing die 28 and the lower pressing die 38 close, accurately pressing the bearing into the target position (such as the equipment shaft system), thus completing the pressing action.
[0023] Multiple telescopic rods 24 (spaced apart) are provided on the inner wall of the pressure plate 23 and gradually contact the upper surface of the bearing as the pressure plate 23 descends. The telescopic rods 24, through their elastic expansion and contraction characteristics, can adapt to slight height differences or local tilts on the bearing surface, ensuring that the contact surface between the pressure plate 23 and the bearing is uniformly stressed; at the same time, the limiting sleeve 25 at one end of the telescopic rod 24 mechanically limits the expansion and contraction stroke to avoid excessive compression that could cause structural damage.
[0024] The horizontal plate 27 connected to the bottom of the telescopic rod 24 cooperates with the upper pressing mold 28 through the limiting block 26. The limiting block 26 provides secondary constraint on the horizontal position of the horizontal plate 27, ensuring that the axis of the upper pressing mold 28 and the lower pressing mold 38 are completely coincident, thus completely solving the pressing tilt problem caused by bearing posture deviation in the traditional gripping method.
[0025] As the servo motor 21 continuously outputs power, the pressure plate 23 drives the upper die 28 to press down vertically, precisely pressing the bearing into the target position. After the set pressing force or displacement is reached, the servo motor 21 reverses and drives the pressure plate 23 to reset through the transmission rod 22, completing a single pressing cycle.
[0026] The transmission assembly includes a drive motor 31, a drive rod 32, and a support block 33. The drive motor 31 is located at one end of the support assembly, the drive rod 32 is located inside the drive motor 31, and the support block 33 is located on the upper surface of the support assembly and connected to the drive rod 32. It also includes a sliding block 34, a sliding guide rail 35, and a moving plate 36. The sliding guide rail 35 is located on the upper surface of the support assembly, the sliding block 34 is located on the inner side wall of the sliding guide rail 35 and can reciprocate laterally relative to the sliding guide rail 35, and the moving plate 36 is located between the sliding block 34 and the drive rod 32. The upper surface of the moving plate 36 is provided with a support foot 37, the upper surface of the support foot 37 is provided with a worktable 39, and the upper surface of the worktable 39 is provided with a pressing die 38 for placing materials.
[0027] Specifically, the transmission component is powered by a drive motor 31. The drive rod 32 rotates inside the drive motor 31 and drives the moving plate 36 to move laterally along the sliding guide rail 35 through a mechanical transmission structure (not shown). The sliding block 34 at the bottom of the moving plate 36 cooperates with the sliding guide rail 35 to ensure the straightness of the movement trajectory. At the same time, the moving plate 36 is connected to the worktable 39 through the support foot 37. The worktable 39 is equipped with a pressing die 38 (used to support the bearing to be pressed).
[0028] When the drive motor 31 starts, the moving plate 36 drives the worktable 39 to move laterally from the initial position to the pressing station, so that the pressing mold 38 is accurately positioned directly below the pressing assembly, completing the transmission and initial positioning of the bearing.
[0029] The support assembly includes a base 11 and a support rod 12. The support rod 12 is located on the upper surface of the base 11. A drive motor 31 is located at one end of the base 11. A support block 33 is located on the upper surface of the support block 33. A sliding guide rail 35 is located on the upper surface of the base 11. A fixing plate 13 is provided on the upper surface of the support rod 12. The upper surface of the fixing plate 13 is located on the support frame 14. A servo motor 21 is located on the upper surface of the support frame 14.
[0030] Specifically, the support assembly forms the framework of the entire mechanism, consisting of a base 11, a support rod 12, a fixing plate 13, and a support frame 14. The base 11 serves as the bottom support, providing a stable mounting surface; the support rod 12 is vertically fixed to the upper surface of the base 11, ensuring the stability of the overall structure through a rigid connection; the fixing plate 13 is horizontally connected to the top of the support rod 12 and is used to support the servo motor 21 of the press-fit assembly; the support frame 14 is fixed to the upper surface of the fixing plate 13, providing a mounting position for the servo motor 21.
