In some embodiments, referring to fig. 7-8, the ball retrieving portion 6 includes an annular material retrieving plate 62 capable of being sleeved on the rotating body 1, the annular material retrieving plate 62 is provided with a plurality of material retrieving channels 61 distributed in a circumferential array, an inlet of each material retrieving channel 61 is located on an upper end surface of the annular material retrieving plate 62, so that the balls 22 in the ball loading holes 51 can directly fall into the inlet of the material retrieving channel 61, an outlet of each material retrieving channel 61 is located on an inner annular surface of a lower end portion of the annular material retrieving plate 62, so that the balls 22 can directly fall into the assembly area of the annular retainer 21 from the inner annular surface of the annular material retrieving plate 62 when the annular material retrieving plate 62 is sleeved on the rotating body 1 (and the annular retainer 21). It should be noted that the inner diameter of the inner annular surface of the annular material-taking plate 62 is larger than the outer diameter of the ball retainer 21 to ensure that the annular material-taking plate 62 can be sleeved on the ball retainer 21.
In the material taking channel 61, because the steel balls 22 enter the inner annular surface of the annular material taking plate 62 from the upper end of the annular material taking plate 62, a section of the material taking channel 61 is inclined or bent, and when the material taking channel 61 is directly arranged in an inclined shape from top to bottom, the falling speed of the steel balls 22 is slower, therefore, in some embodiments, the material taking channel 61 is arranged as an upper channel and a lower channel which are communicated, the upper channel is arranged along the vertical direction to ensure the falling speed of the steel balls 22, and the lower channel is arranged at the lower end of the annular material taking plate 62 and inclines downwards from the outer annular surface of the annular material taking plate 62 to the inner annular surface of the annular material taking plate 62.

The problem that the steel balls 22 cannot fall onto the steel ball retainer 21 because of being clamped in the second inclined groove 6221 can be effectively avoided through the arrangement of the steel ball assembling part 7.
Specifically, the pressing rod 71 is disposed on the annular material taking plate 62 in a penetrating manner, and one end of the pressing rod 71 can extend into the second inclined groove 6221 of the corresponding material taking channel 61, and the pressing rod 71 is disposed in an inclined manner, and the inclined direction of the pressing rod 71 gradually inclines downwards from the outer ring surface of the annular material taking plate 62 to the inner ring surface of the annular material taking plate 62, so that the pressing rod 71 can apply a downward-inclined pushing force to the steel balls 22 when pushing the steel balls 22, and the steel balls 22 can conveniently fall down. The pressing rod 71 penetrates through the annular material taking plate 62, so that the synchronous rotation of the pressing rod 71 along with the annular material taking plate 62 can be ensured, and the accurate pressing of the pressing rod 71 on the steel balls 22 in the material taking channel 61 is further ensured.
Furthermore, as shown in fig. 10, the pressure lever 71 is further provided with a guide groove 711 arranged along the expansion direction thereof, the lower end of the annular material taking plate 62 is further fixedly connected with an annular end cover 64, the annular end cover 64 is provided with guide rods 641 arranged in one-to-one correspondence with the pressure lever 71, the guide rods are inserted into the guide grooves 711 of the corresponding pressure lever 71 along the vertical direction, and when the pressure lever 71 expands and contracts, the guide grooves 711 can move along the corresponding guide rods 641 to guide the expansion direction of the pressure lever 71.

The up-and-down movement of the platen 72 is realized by the assembly cylinder 73, and the synchronous driving of all the press rods 71 is realized by the arrangement of the annular platen 721.
In some embodiments, the assembly driving member further includes a spring (not shown) sleeved on the pressing rod 71, and two ends of the spring abut against the annular material taking plate 62 and the pressing rod 71 respectively. When the spring is in a natural state, the annular pressing surface 721 is not abutted to the pressing rod 71, and at this time, the pressing rod 71 is at a position farthest from the steel balls 22.
When the steel ball moving mechanism assembles the steel balls 22 on the steel ball retainer 21, if the steel ball moving mechanism moves upwards, the assembled steel balls 22 may fall off from the steel ball retainer 21 because the outer side of the steel balls 22 lacks an effective limiting mechanism, so in some embodiments, the assembling table 3 is further integrated with a lower casing assembling part, which not only realizes the assembly of the lower casing, but also can limit the assembled steel balls. Specifically, the lower shell assembly portion includes a lower shell 24 pre-mounted on the rotating body 1 and located below the ball retainer 21, and the lower shell 24 can move up to the assembly area of the ball retainer 21 under the action of the lower shell driving member and is sleeved outside the balls 22 to prevent the balls 22 from falling off the ball retainer 21.
