Technical Field

[0001] This invention relates to the field of mechanical automation technology, and more specifically, to an automatic ball filling device for thin-walled bearing cages. Background Technology

[0002] Due to the large width-to-diameter ratio of thin-walled bearings, a large number of steel balls need to be filled between the inner and outer rings. Traditional manual ball filling methods have the following drawbacks: 1. Uneven number and distribution of steel balls between bearings; 2. Lack of a retainer to hold the balls together, resulting in unequal angles between adjacent balls and uneven stress during use; 3. Inability to guarantee a sufficient number of steel balls between the inner and outer rings, leading to poor overall performance. Therefore, this invention proposes an automatic steel ball filling device for thin-walled bearing cages. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic ball filling device for thin-walled bearing cages, which features automatic filling and convenient filling.

An annular groove is provided on the disc for positioning the bottom of the cage. The annular groove is coaxial with the disc. An inner retaining ring is provided on the disc and rotates with it on the inner side of the annular groove. A middle retaining ring and an outer retaining ring are provided on the outer side of the annular groove, suspended above the disc. The outer retaining ring is located outside the middle retaining ring. A closed annular feeding groove is formed between the outer retaining ring and the middle retaining ring and located above the disc. A first partition is provided within the feeding groove, separating it. One end of the first partition is a feeding head end, and the other end is a feeding tail end. A feeding pipe is provided above the feeding tail end. A filling port is provided on the middle retaining ring on the inner side of the feeding head end, and a pressing port is provided on the outer retaining ring on the outer side.

[0019] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0021] Example 1

[0022] See Figures 1 to 3As shown, the automatic ball filling device for a thin-walled bearing cage involved in this embodiment includes a disc 1 that rotates horizontally around its own axis. An annular groove 2 is formed on the disc 1 for positioning the bottom of the cage. The annular groove 2 is coaxial with the disc 1. An inner retaining ring 3 is provided on the inner side of the annular groove 2 and rotates with it on the disc. A middle retaining ring 4 and an outer retaining ring 5 are provided on the outer side of the annular groove 2, suspended above the disc. The outer retaining ring 5 is located outside the middle retaining ring 4. The outer retaining ring 5 and the middle retaining ring 4 form a closed annular shape and are located above the disc 1. The feeding trough 6 has a first partition 7 that separates it. One end of the first partition 7 is the feeding head end 61 and the other end is the feeding tail end 62. The feeding tail end 62 is provided with a feeding pipe 8. The inner side of the feeding head end 61 is provided with a filling port 9 opened on the middle baffle ring 4, and the outer side is provided with a pressing port 10 opened on the outer baffle ring 5. The pressing port 10 is provided with a pressing rod 11 and a linear reciprocating motion mechanism (not shown in the figure) that controls the pressing rod to move radially along the disc body; the linear reciprocating motion mechanism is a push rod cylinder.

[0023] Furthermore, it also includes an external suspension 14, on which the middle retaining ring 4 and the outer retaining ring 5 are fixed.

[0024] Furthermore, the bottom of the annular groove 2 is provided with a positioning protrusion 16 that is adapted to the bottom groove of the retainer.

[0025] In this embodiment, the positioning and clamping of the retainer to be fitted with steel balls is achieved by using the annular groove 2 and the positioning protrusion 16 provided at the bottom of the groove. Then, steel balls are supplied to the feeding groove 6 by the feeding pipe 8. As the disc 1 rotates, the steel balls gradually fill the feeding groove 6. Finally, the pressing rod 11, which moves radially along the disc, presses the steel balls against the first partition 7 into a steel ball fitting hole in the retainer. If the retainer has 24 fitting holes, one steel ball is pressed in for every 105° rotation of the disc 1. Each 105° rotation of the disc 1 includes 90° for pushing the steel ball into the feeding groove 6, and the remaining 15° for switching the fitting holes on the retainer, until all 24 fitting holes are filled with steel balls.

[0026] Example 2

[0027] See Figures 1 to 3 As shown, the thin-walled bearing cage automatic ball filling device involved in this embodiment is further configured, based on embodiment 1, with the first partition 7 provided with a magnet 12 for adsorbing steel balls.

[0028] In this embodiment, a magnet 12 is provided on the first partition 7 to attract and position the steel ball closest to the first partition 7, which facilitates the pushing of the pressing rod 11 and the pressing.

[0029] Example 3

[0030] See Figures 1 to 3 As shown, the thin-walled bearing cage steel ball automatic filling device involved in this embodiment is further configured based on embodiment 2, wherein the feeding groove 6 is provided with a second partition 13 that separates it, and the second partition 13 is close to the first partition 7.

[0031] In this embodiment, a second partition 13 is provided in the feeding trough 6, spaced apart from the first partition 7, to block the steel balls that are close to the first partition 7. This prevents the steel balls at the other end (feeding tail end 62) from being attracted to the first partition 7 due to being too close to the first partition 7, thus preventing them from being automatically fed in the feeding trough 6 along with the disc body 1.

[0032] Example 4

[0033] See Figures 1 to 3 As shown, the thin-walled bearing cage steel ball automatic filling device involved in this embodiment is further configured based on embodiment 1, wherein the bottom of the feeding groove 6 is provided with a protruding structure 15 for feeding steel balls from the feeding tail end to the feeding head end, and the protruding structure 15 is provided on the disc body 1.

[0034] In this embodiment, by arranging a protruding structure 15 at the bottom of the feeding trough 6, the steel balls can be fed from the feeding tail end to the feeding head end using the protruding structure 15 while the disc body 1 is rotating, thus playing an auxiliary pushing role.

[0035] Example 5

[0036] See Figures 1 to 3 As shown, the automatic ball filling device for thin-walled bearing cages involved in this embodiment is further configured, based on embodiment 1, that the end of the pressing rod 11 facing the axis of the disc body 1 has a spherical groove (not shown in the figure).

[0037] In this embodiment, a spherical groove is provided at one end of the pressing rod 11 facing the axis of the disc body 1 to accommodate the steel ball, which plays a role in pressing and positioning and facilitates the pushing of the steel ball.

[0038] The present invention relates to an automatic ball filling device for thin-walled bearing cages. This automatic filling device is equipped with a cage placed between the inner and outer rings of the bearing. The cage is automatically filled with high-density steel balls at equal intervals, ensuring uniform distribution and balanced force distribution. The ball feeding groove and the annular groove for workpiece clamping are nested together, and with the pressing assembly, the overall structure is compact, the equipment is small in size, and occupies little space. Furthermore, the power source for driving the workpiece rotation and the ball replenishment feeding groove is the same, simplifying the structure, achieving a high synchronization rate, and providing complete overall functionality and strong practicality.
