[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0020] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting this application.

[0021] like Figure 1-3 As shown, a fully loaded angular contact bearing ball loading device includes a base plate 1, a column 2, an inner ring placement platform 3, an inner ring placement groove 4, an anti-slip sleeve 5, a delivery pipe 8, a drop pipe 9, a first electric push rod 11, a push column 12, and a fixed frame 17. The column 2 is arranged on the top of the base plate 1, the inner ring placement platform 3 is fixedly arranged on the top of the column 2, the top of the inner ring placement platform 3 has an inner ring placement groove 4 that can accommodate the bearing ring, the anti-slip sleeve 5 is sleeved on the column 2, and the two are slidably matched, the delivery pipe 8 is sleeved on the column 2 and is below the anti-slip sleeve 5, one end of the delivery pipe 8 is connected with the anti-slip sleeve 5, one end of the drop pipe 9 is connected with the wall of the delivery pipe 8, the fixed frame 17 is fixed on the top of the base plate 1, the first electric push rod 11 is horizontally arranged on the fixed frame 17, the first end of the push column 12 is fixedly connected to the output end of the fixed frame 17, and the second end of the push column 12 extends into the delivery pipe 8.

[0022] Specifically, the cross-section of the column 2 is rectangular or elliptical to prevent the anti-slip sleeve 5 from rotating on the column 2. The column 2 is upright and can support the lifting and lowering of the anti-slip sleeve 5. The inner ring placement platform 3 is cylindrical, and an annular inner ring placement groove 4 is provided on the top to facilitate the placement of the bearing ring. The conveying pipe 8 is provided under the anti-slip sleeve 5 and can push the anti-slip sleeve 5 to reset. The sphere falls from the drop tube 9 into the conveying pipe 8, and then is pushed into the raceway of the bearing ring placed inside the inner ring placement groove 4 by the first electric push rod 11 to complete the assembly.

[0023] Furthermore, a positioning column 13 is fixedly provided at the center of the inner ring placement platform 3 for positioning the bearing ring.

[0024] Furthermore, an opening is provided at the bottom of the anti-slip sleeve 5 for the column 2 to pass through, and a hollow assembly cavity 6 is provided in the middle of the anti-slip sleeve 5 to accommodate the inner ring placement platform 3 and the positioning column 13, and an outer ring placement groove 7 is provided on the inner side of the top of the anti-slip sleeve 5 to accommodate the outer ring of the bearing.

[0025] Specifically, the opening at the bottom of the anti-slip sleeve 5 slides with the column 2 to rise and fall on the column 2. The assembly cavity 6 is arranged axially along the anti-slip sleeve 5. The heated bearing outer ring is placed on the inner side of the outer ring placement groove 7, and then pressure is applied to assemble the bearing outer ring on the outside of the bearing inner ring. At the same time, the inner ring placement platform 3 supports the bearing inner ring and the ball to prevent the bearing outer ring from being installed improperly.

[0026] Furthermore, a hopper 10 is provided at one end of the drop pipe 9 away from the conveying pipe 8 for temporarily storing the balls.

[0027] Furthermore, it also includes a bracket 14, a second electric push rod 15, and a pressure plate 16. The bottom of the bracket 14 is fixedly connected to the base plate 1, and the second electric push rod 15 is vertically fixedly installed on the top of the bracket 14. The output end of the second electric push rod 15 is downward and fixedly connected to the pressure plate 16. The pressure plate 16 is coaxial with the column 2 and the anti-slip sleeve 5.

[0028] Specifically, the second electric push rod 15 is started to extend and drive the pressing plate 16 to descend, and the pressing plate 16 presses the outer ring of the bearing to facilitate assembly.

[0029] Furthermore, the interface between the delivery tube 8 and the assembly cavity 6 corresponds to the raceway of the bearing ring placed in the inner ring placement groove 4 so that the ball can smoothly roll into the raceway after entering the anti-drop sleeve 5 from the delivery tube 8.

[0030] In the above structure, the inner ring of the bearing is placed on the inside of the inner ring placement groove 4, the ball to be installed is placed in the hopper 10, and the extension is started to drive the push column 12 to push the ball transported by the drop tube 9 into the raceway of the bearing ring. By repeating the push, the ball can be continuously fed into the raceway. When the ball is full, the heated outer ring of the bearing is placed on the inside of the outer ring placement groove 7, and then the second electric push rod 15 is started to extend to drive the pressure plate 16 to descend. The pressure plate 16 presses the outer ring of the bearing to make the ball enter the raceway of the outer ring of the bearing to complete the assembly. At the same time, the delivery tube 8 is compressed during the downward pressing process. When the second electric push rod 15 contracts, the elastic force of the delivery tube 8 pushes the anti-slip sleeve 5 to rise and reset to facilitate the next assembly.

[0031] The above shows and describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements are intended to fall within the scope of the present application.
