[0023] The embodiment of the present application provides a motor end cover bearing filling equipment, which comprises a storage circular pipe 1, a guide rail 2, a filling mechanism 3 and the like. Figures 1-5 As shown in the figure, the filling mechanism comprises a storage circular pipe 1, a guide rail 2, a filling mechanism 3 and the like.

[0024] The storage circular pipe 1 is vertically arranged and is arranged to move along its axis, the inner diameter of the storage circular pipe 1 is matched with the outer diameter of the bearing 4, that is, a plurality of bearings 4 can be horizontally loaded into the storage circular pipe 1; the guide rail 2 is horizontally arranged below the storage circular pipe 1, the guide rail 2 is provided with a tray 21 which is arranged to move along the length of the guide rail 2, the tray 21 can be driven by a motor matched with a synchronous belt, a motor matched with a chain or the like, and the tray 21 is used for horizontally placing the end cover 5; the filling mechanism 3 comprises a baffle 31 which is horizontally arranged at the lower end of the storage circular pipe 1 and a transmission unit 32 which acts on the baffle 31, and the transmission unit 32 is used for making the baffle 31 move away from or close to the axis of the storage circular pipe 1 in the horizontal direction with the lowering or lifting of the storage circular pipe 1.

[0025] In application, the storage circular pipe 1 is located above the guide rail 2 at a predetermined height, the baffle 31 is close to the axis of the storage circular pipe 1, the lower end of the storage circular pipe 1 can be blocked, at this time, a plurality of bearings 4 can be sequentially filled into the storage circular pipe 1; after the storage circular pipe 1 is filled, the tray 21 which horizontally carries the end cover 5 is moved along the length direction of the guide rail 2 to below the storage circular pipe 1, the storage circular pipe 1 starts to descend along its axis, in the descending process, the baffle 31 moves away from the axis of the storage circular pipe 1 in the horizontal direction under the action of the transmission unit 32, when the lower end of the storage circular pipe 1 abuts against the end cover 5, the baffle 31 moves out of the lower end of the storage circular pipe 1, the lower end of the storage circular pipe 1 is opened, the bearing 4 falls into the end cover 5 in the vertical direction, then the storage circular pipe 1 is lifted, the baffle 31 moves close to the axis of the storage circular pipe 1 in the horizontal direction under the action of the transmission unit 32, so that the filled bearing 4 is separated from the bearing above it, waiting for the filling of the next end cover 5; the tray 21 which fills the bearing 4 is moved to a pressing equipment for pressing. Through the arrangement of the storage circular pipe 1 and the cooperation of the baffle 31 and the transmission unit 32, the lower end of the storage circular pipe 1 can be opened and closed with the lifting thereof, so that the automatic filling of the bearing 4 is realized, the filling efficiency of the bearing 4 is improved, and the overall assembly efficiency of the motor is improved.

[0026] Specifically, as shown in the figure, Figure 2As shown in the figure, the storage tube 1 protrudes outward to form a mounting cavity 11. A baffle 31 is located at the lower end of the mounting cavity 11 and is horizontally movable. The transmission unit 32 includes a movable rod 321 that passes vertically through the mounting cavity 11. One end of the baffle 31 is hinged to one end of a connecting rod 322, and the other end of the connecting rod 322 is hinged to the movable rod 321. The two hinge axes are horizontal and perpendicular to the direction of movement of the movable rod 321. The movable rod 321 can move up or down along its own axis as the storage tube 1 rises or falls. In application, the hinges between the two ends of the connecting rod 322 and the baffle 31 and the movable rod 321 convert the movement of the movable rod 321 along its own axis into the horizontal movement of the baffle 31. The movable rod 321 cooperates with the storage tube 1; when the storage tube 1 rises or falls, the movable rod 321 rises or falls along its own axis, thereby moving the baffle 31. This makes the filling equipment structure relatively compact and easy to maintain.

[0027] After the lower end of the storage tube 1 abuts against the end cap 5 and filling is completed, the storage tube 1 moves upward. During this upward movement, the baffle 31 may not move closer to the axis of the storage tube 1 in time, resulting in incomplete separation of the filled bearing 4 from the bearing 4 above it, or causing multiple bearings 4 to be filled at once. To address the above problems, this embodiment proposes a preferred solution, as follows: Figures 2-4 As shown, the upper end of the movable rod 321 is provided with a limiting platform 323, and the transmission unit 32 also includes a spring 324 sleeved on the movable rod 321. The spring 324 is connected between the limiting platform 323 and the top of the mounting cavity 11. When the spring 324 is in its natural state, the hinge axis of one end of the connecting rod 322 is lower than the hinge axis of the other end. A mating block 325 is provided below the movable rod 321, and the mating block 325 is movable in the vertical direction.

[0028] In use, the storage pipe 1 is located at a predetermined height above the guide rail 2, the spring 324 is in a natural state, the hinged shaft of one end of the connecting rod 322 is lower than that of the other end, and the baffle 31 blocks the lower end of the storage pipe 1; the storage pipe 1 starts to descend, and the movable rod 321 synchronously descends; when the movable rod 321 abuts against the matching block 325, the storage pipe 1 continues to descend, the spring 324 is stretched by the storage pipe 1, the movable rod 321 rises relative to the storage pipe 1, and the baffle 31 is pulled away from the axis of the storage pipe 1; until the lower end of the storage pipe 1 abuts against the end cover 5, the baffle 31 moves out of the storage pipe 1, and the filling is completed; due to the action of the spring 324, the lower end of the movable rod 321 abuts against the matching block 325, and before the storage pipe 1 rises, the matching block 325 first descends in the vertical direction, the spring 324 is contracted to the natural state, the movable rod 321 moves downward, and the baffle 31 is inserted between the filled bearing 4 and the bearing 4 above it, so that the separation of the bearing 4 is completed; then the storage pipe 1 rises for the next filling, and the matching block 325 rises to the initial position. Under the action of the spring 324 and the matching block 325, the filled bearing 4 can be effectively separated from the unfilled bearing 4 after the storage pipe 1 completes the filling, the problem of incomplete separation of the bearing 4 or filling of multiple bearings 4 at a time is avoided, and the reliability of the filling device is improved.

[0029] Specifically, as shown in Figures 2-5 , the mounting cavity 11 is formed with two and located on both sides of the storage pipe 1, the lower end of the mounting cavity 11 is provided with a baffle 31, and the mounting cavity 11 is provided with a transmission unit 32 and acts on the corresponding baffle 31. The two baffles 31 not only can effectively support the bearings 4 in the storage pipe 1, but also can enter from both sides of the bearing 4 at the same time when separating the bearing 4, thereby improving the separation efficiency of the bearing 4.

[0030] Specifically, as shown in Figure 4 and Figure 5 , the bottom end of the storage pipe 1 is provided with a matching groove 12 along the inner circular contour, the end cover 5 is provided with a placement ring 51, the matching groove 12 can cooperate with the placement ring 51, and the baffle 31 is located at a predetermined distance above the matching groove 12. When the storage pipe 1 moves downward to abut against the placement ring 51 on the end cover 5, the ring body of the placement ring 51 is embedded into the annular groove 12, at this time, the axis of the storage pipe 1 coincides with the axis of the placement ring 51, so that the bearing 4 remains horizontal after falling, thereby facilitating the subsequent press-fitting process, avoiding the problem that the bearing 4 deviates from the horizontal position due to manual filling of the bearing 4, and further improving the assembly efficiency of the motor as a whole; the baffles 31 are separated by a width of one bearing 4 between the grooves 12, so as to facilitate the separation of the bearing 4.

[0031] Preferably, as shown in Figures 2-5As shown, the baffle 31 is connected with a horizontally arranged guide rod 311, and the installation cavity 11 on both sides of the guide rod 311 is provided with a horizontally arranged guide wheel 312, and the circumferential side of the guide wheel 312 is provided with a horizontally arranged annular groove 313, and both sides of the guide rod 311 are matched in the annular groove 313. Through the cooperation of the guide wheel 312 and the guide rod 311, and by using the horizontal force transmitted to the guide rod 311 by the movable rod 321 and the connecting rod 322, the stroke of the baffle 31 is not interfered, and the reliability of the filling device is further improved.

[0032] Specifically, the lifting of the storage circular pipe 1 and the matching block 325 can adopt other driving modes such as linear air cylinder, electric cylinder, rack and the like.

[0033] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
