Detailed Implementation

[0017] like Figures 1 to 11 As shown, this embodiment provides a bearing press-fitting device. The device has a steel ring feeding station, a bearing feeding station, a pre-pressing station, a pressing station, and a finished product unloading station. The device includes a rotating table 6, a bearing feeding mechanism 2, a steel ring feeding mechanism 1, a pre-pressing mechanism 3, a pressing mechanism 4, and a finished product unloading mechanism 5, wherein: Initially, the steel ring 8 and the bearing 9 are independent of each other, with the steel ring 8 being annular. After being pressed by the bearing pressing device, the steel ring 8 is fitted onto the outside of the bearing 9.

[0018] The bearing loading mechanism 2 is located at the bearing loading station and is used to transfer the bearing to the rotating table 6; the steel ring loading mechanism 1 is located at the steel ring loading station and is used to transfer the steel ring to the bearing located on the rotating table 6; the pre-pressing mechanism 3 is located at the pre-pressing station and is used to push the steel ring into the bearing so that the upper end face of the steel ring is flush with the upper end face of the bearing, or the upper end face of the steel ring is slightly higher than the upper end face of the bearing; the clamping mechanism 4 is located at the clamping station and is used to push the steel ring located outside the bearing so that the upper end face of the steel ring is lower than the upper end face of the bearing; the finished product unloading mechanism 5 is located at the finished product unloading station and is used to transfer the clamped steel ring and bearing out.

[0019] The steel ring feeding mechanism 1 includes a steel ring feeding tray 17, a steel ring feeding platform 11, and a limiting component. The steel ring enters the steel ring feeding platform 11 from the steel ring feeding tray 17. The steel ring feeding platform 11 is located outside the rotating table 6. A steel ring moving channel is provided on the steel ring feeding platform 11. Positioning plates 12 are provided on opposite sides of the steel ring moving channel. The positioning plates 12 are located at the end of the steel ring moving channel and are positioned opposite to the limiting component. The steel ring is positioned between the two positioning plates 12. The distance between the two positioning plates 12 is adjustable. The distance between the two positioning components can be adjusted according to different steel ring sizes, which is highly versatile and flexible, and will not compress the steel ring.

[0020] In a preferred embodiment, the positioning plate 12 and the steel ring feeding platform 11 are provided with corresponding openings. The positioning plate 12 and the steel ring feeding platform 11 are connected by installing fasteners in the openings. The openings on the positioning plate 12 are elongated and extend in a direction perpendicular to the moving direction of the steel ring. By moving the positioning plate 12 to a suitable position and then installing fasteners in the openings, the positioning plate 12 and the steel ring feeding platform 11 are fixedly connected. The adjustment is flexible and quick, and the operation is simple.

[0021] The limiting component is located at the end of the steel ring moving channel. The limiting component includes a limiting drive 13 and a limiting component 14. The limiting drive 13 is connected to the limiting component 14 to drive the limiting component 14 to move in a direction perpendicular to the moving direction of the steel ring. The limiting component 14 is used to abut against the steel ring located between the two positioning plates 12 to prevent the steel ring from leaving the steel ring moving channel and wait for the steel ring feeding mechanism 1 to grab the steel ring, ensuring stable grabbing of the steel ring. The limiting component 14 can move to limit and position steel rings of different sizes, which is highly versatile.

[0022] In this example, the steel ring feeding mechanism 1 also includes a steel ring feeding drive assembly 16 and a steel ring feeding gripper 18. The steel ring feeding drive assembly 16 is connected to the steel ring feeding gripper 18 to drive the steel ring feeding gripper 18 to move in the horizontal and vertical directions. The steel ring feeding gripper 18 is used to grab the steel ring on the steel ring feeding platform 11 and transfer it to the corresponding steel ring feeding station on the rotating platform.

[0023] See Figure 4The steel rim feeding drive assembly 16 includes a first mounting component 161, a second mounting component 162, a third mounting component 163, a first steel rim feeding drive component 164, and a second steel rim feeding drive component 165. The main body of the first steel rim feeding drive component 164 is disposed on the first mounting component 161, and the second mounting component 162 is movably disposed on the first mounting component 161. The first steel rim feeding drive component 164 is connected to the second mounting component 162 to drive the second mounting component 162 to move horizontally. The main body of the second steel rim feeding drive component 165 is disposed on the second mounting component 162, and the third mounting component 163 is movably disposed on the second mounting component 162. The steel rim feeding gripper 18 is connected to the third mounting component 163. The second steel rim feeding drive component 165 is connected to the third mounting component 163 to drive the third mounting component 163 and the steel rim feeding gripper 18 to move vertically to flexibly grip the steel rim located on the steel rim feeding platform 11.

[0024] Preferably, both the first mounting member 161 and the second mounting member 162 are provided with limiting buffers. The upper limit buffer of the first mounting member 161 is located at one end of the first mounting member 161 along its length, which can limit the movement of the second mounting member 162 to prevent the second mounting member 162 from detaching from the first mounting member 161, thus providing a protective function. The upper limit buffer of the second mounting member 162 is located at the lower end of the second mounting member 162, which can limit the movement of the third mounting member 163 to prevent the third mounting member 163 from detaching from the second mounting member 162, thus providing a protective function.

[0025] See Figure 4 The third mounting member 163 has a first stop 1631, which can abut against the upper limit buffer of the second mounting member 162.

[0026] See Figure 1-2 The steel ring feeding gripper 18 includes multiple steel ring feeding chucks, which are circumferentially distributed and can grip the same steel ring together, ensuring stable gripping.

[0027] In a preferred embodiment, the limiting member 14 is provided with a sensing component 15, which is used to detect the steel ring located at the end of the steel ring moving channel. Based on the sensing result of the sensor, the steel ring feeding claw 18 grabs the steel ring.

[0028] In some embodiments, the bearing loading mechanism 2 includes a bearing loading tray 24, a bearing loading platform 21, a bearing loading drive assembly 23, and bearing loading grippers 22. Bearings enter the bearing loading platform 21 from the bearing loading tray 24. The bearing loading platform 21 is located outside the rotating table 6 and has a bearing movement channel. The bearing loading drive assembly 23 is connected to the bearing loading grippers 22 to drive the bearing loading grippers 22 to move horizontally and vertically. The bearing loading grippers 22 are used to grasp the steel rings on the bearing loading platform 21 and transfer them to the bearing loading station.

[0029] See Figure 3 The bearing loading drive assembly 23 includes a first support member 231, a second support member 232, a third support member 233, a first bearing loading drive member 234, and a second bearing loading drive member 235. The main body of the first bearing loading drive member 234 is disposed on the first support member 231, and the second support member 232 is movably disposed on the first support member 231. The first bearing loading drive member 234 is connected to the second support member 232 to drive the second support member 232 to move horizontally. The main body of the second bearing loading drive member 235 is disposed on the second support member 232, and the third support member 233 is movably disposed on the second support member 232. The bearing loading gripper 22 is connected to the third support member 233. The second bearing loading drive member 235 is connected to the third support member 233 to drive the third support member 233 and the bearing loading gripper 22 to move vertically to flexibly grip the bearing located on the bearing loading platform 21.

[0030] Preferably, both the first support member 231 and the second support member 232 are provided with limit buffers 25. The upper limit buffer of the first support member 231 is located at one end of the first support member 231 along its length, which can limit the movement of the second support member 232 to prevent the second support member 232 from detaching from the first support member 231, thus providing a protective function. The upper limit buffer of the second support member 232 is located at the lower end of the second support member 232, which can limit the movement of the third support member 233 to prevent the third support member 233 from detaching from the second support member 232, thus providing a protective function.

[0031] See Figure 3 The third support member 233 has a second stop 2331, which can abut against the upper limit buffer of the second support member 232.

[0032] See Figure 3 The bearing loading jaw 22 includes multiple bearing loading chucks, which are circumferentially distributed and can grip the same bearing together, ensuring stable gripping.

[0033] In some embodiments, the preload mechanism 3 includes a preload drive 31 and a preload head 32. The preload drive 31 is connected to the preload head 32 to drive the preload head 32 to move vertically. The preload head 32 preloads the steel ring so that the upper end face of the steel ring is flush with the upper end face of the bearing or slightly higher than the upper end face of the bearing. The preload mechanism 3 gently preloads the steel ring so that it fits onto the bearing, thus providing a guiding function.

[0034] In some embodiments, the preload head 32 is preferably cylindrical, with its lower end face being flat, allowing it to abut against the upper end face of the steel ring and smoothly push the steel ring. Preferably, the lower end face of the preload head 32 has an upwardly recessed positioning groove, which engages with a protrusion on the bearing. The protrusion extends into the positioning groove, restricting bearing movement, ensuring precise positioning, and preventing the steel ring from being missed.

[0035] In some embodiments, the clamping mechanism 4 includes a clamping drive 41 and a clamping head 42. The clamping drive 41 is connected to the clamping head 42 to drive the clamping head 42 to move vertically. Without the pre-pressing mechanism 3, when the steel ring feeding mechanism 1 moves the steel ring onto the bearing, the steel ring may shift. If the clamping head 42 is used to clamp the steel ring directly, it may damage the steel ring, resulting in the steel ring not being pressed into place.

[0036] In some embodiments, the lower end of the clamping head 42 has an upward-recessed groove, the annular peripheral wall of which abuts against the outer periphery of the steel ring to push the steel ring downward along the bearing until the lower end face of the steel ring is flush with the lower end face of the bearing. The clamping head 42 may be cylindrical.

[0037] Furthermore, the support assembly is located below the rotating table and below the pressing head. The support assembly includes a support 71 and a roller 72 rotatably mounted on the support 71. The roller 72 is directly opposite the pressing head. When the bearing and steel ring are below the pressing head 42, and the pressing head 42 presses the steel ring, it causes a large force impact on the part of the rotating table corresponding to the pressing head, which can easily lead to bending deformation at that point. The roller 72 is provided to support this part, reduce the impact, and protect the rotating table.

[0038] In this example, the finished product unloading station includes a finished product unloading drive assembly and a finished product unloading gripper 51. The finished product unloading drive assembly is connected to the finished product unloading gripper 51 to drive the finished product unloading gripper 51 to move in the horizontal and vertical directions. The finished product unloading gripper 51 is used to grip the finished product located at the finished product unloading station and transfer it.

[0039] See Figure 11The finished product unloading drive assembly includes a linear module 52 and a finished product unloading longitudinal drive component 53. The linear module 52 is connected to a bracket. The linear module 52 is connected to the finished product unloading longitudinal drive component 53 to drive the linear module 52 to move in the horizontal direction. The finished product unloading gripper 51 is connected to the finished product unloading longitudinal drive component 53 to drive the finished product unloading gripper 51 to move in the vertical direction.

[0040] See Figure 11 The bracket includes two columns and a connector. The connector is connected to both columns and is cross-shaped. The connector includes a horizontal section and a vertical section. The linear module 52 is set on the horizontal section.

[0041] The finished product unloading gripper 51 includes multiple finished product unloading chucks, which are circumferentially distributed and can jointly grip the same finished product.

[0042] The finished product unloading station also includes an unloading guide 54 and a receiving container 55. The unloading guide 54 is inclined, and the receiving container 55 is located below the unloading guide 54 to receive the finished product.

[0043] The specific implementation of the bearing press-fitting device in this example is as follows: The bearing loading gripper picks up the bearing and places it on the rotating table. The rotating table rotates, and the bearing moves to the corresponding steel ring loading station. The steel ring loading gripper picks up the steel ring and places it on the bearing. The rotating table continues to rotate to the corresponding pre-pressing station. The pre-pressing head first gently presses the steel ring into the bearing so that the upper end face of the steel ring is flush with the upper end face of the bearing or slightly higher than the upper end face of the bearing. Next, the rotating table continues to rotate to the corresponding pressing station. The pressing head pushes the steel ring located outside the bearing so that the upper end face of the steel ring is lower than the upper end face of the bearing. Finally, the rotating table continues to move to the corresponding finished product unloading station. The finished product unloading gripper transfers the pressed steel ring and the finished bearing out, realizing automated bearing press-fitting.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model.
