Specifically, ball selecting assembly 312 includes a ball selecting block 3121 and a ball selecting block driving member 3122, ball selecting block 3121 has a through ball passing hole 3123, and ball selecting block driving member 3122 is configured to drive ball selecting block 3121 to move along steel ball feeding member 311, drive ball selecting block 3121 to push stop 3112 into steel ball feeding member 311. Ball outlet member 313 is located below steel ball feeding member 311 and is in sliding fit with ball selecting block 3121, and ball outlet member 313 is provided with a ball outlet 3131 which can be communicated with ball passing hole 3123. When a steel ball is selected, the ball selecting block 3121 is moved horizontally along the steel ball feeding member 311 to the corresponding steel ball feeding hole 3111, then the ball selecting block 3121 is pushed, the ball selecting block 3121 pushes the corresponding stopper 3112 into the steel ball feeding member 311, at this time, the ball passing hole 3123 on the ball selecting block 3121 is butted with the corresponding steel ball feeding hole 3111, the steel ball in the steel ball feeding hole 3111 enters the ball selecting block 3121, then the ball selecting block 3121 is retreated, the corresponding stopper 3112 is extended to block the corresponding steel ball feeding hole 3111, the ball selecting block 3121 is translated to the ball outlet hole 3131 of the ball outlet member 313, the ball passing hole 3123 is butted with the ball outlet hole 3131, and the steel ball falls into the ball outlet hole 3131 and enters the ball adding assembly 321.

The ball adding assembly 321 of the present invention includes a ball adding member 3211, a ball adding member driving member 3212, a ball pushing member 3213 and a ball pushing member driving member 3214. The ball adding piece 3211 is provided with a through ball guide passage 3215, one end of the ball guide passage 3215 is communicated with the ball outlet hole 3131 through a guide tube, and the ball adding piece driving piece 3212 is configured to drive the ball adding piece 3211 to move up and down; the ball pushing element 3213 penetrates the ball adding element 3211 and can extend out of the end of the ball guide passage 3215 which is not connected with the ball outlet 3131; the ball pushing member driving member 3214 is configured to drive the ball pushing member 3213 to move up and down with respect to the ball adding member 3211. That is, the steel ball falls into the ball outlet hole 3131 and then enters the ball guide channel 3215 along the guide tube, and the ball pushing element 3213 descends once per liter to push one steel ball between the inner ring and the outer ring of the bearing. The purpose of lowering the ball adding member 3211 is to press the outer race of the bearing to prevent the outer race from wobbling during ball addition. In order to further position the outer ring, an outer ring abutting assembly is further arranged below the ball adding assembly 321, the outer ring abutting assembly includes an abutting rod 3216 and an abutting rod driving member 3217, and the abutting rod driving member 3217 is configured to drive the abutting rod 3216 to abut against the outer ring of the bearing, so as to release the abutting against the outer ring. When the bearing moves to the lower part of the ball adding component 321, the abutting rod driving component 3217 drives the abutting rod 3216 to abut against the outer ring of the bearing for positioning.

After the outer ring is fixed, the inner ring needs to deviate relative to the outer ring to make a ball adding space, the bottom of the ball adding piece 3211 is further provided with a butting piece 3218, the butting piece 3218 is provided with a through hole communicated with the ball guide channel 3215, and the butting piece 3218 is configured to extend between the inner ring and the outer ring of the bearing and make the inner ring deviate from the outer ring. When the ball adding piece 3211 is pressed down, the abutting piece 3218 extends between the outer ring and the inner ring and shifts the inner ring, so that the inner ring deviates safely, balls pushed down by the ball pushing piece 3213 come out from the via holes and enter between the inner ring and the outer ring, and after the ball adding is finished, the ball adding piece 3211 is lifted, and the steel balls are blocked by the ball pushing piece 3213 and cannot come out from the via holes.

After the ball is added, the fitting operation is required, the fitting assembly 322 of the present invention includes a top rod 3221 and a top rod driving member 3222, the top rod 3221 can extend into an inner ring of the bearing, and the top rod driving member 3222 is configured to drive the top rod 3221 to move up and down and horizontally. When the bearing reaches the lower part of the ball adding assembly 321, the push rod 3211 rises to penetrate into the inner ring, then the ball adding piece 3211 presses downwards to add balls, after the ball adding is finished, the ball adding piece 3211 is lifted, the push rod driving piece 3222 drives the push rod 3221 to move, the inner ring and the outer ring are coaxial, the sleeve combining operation is finished, and finally the push rod 3221 descends to prepare for the next sleeve combining operation.

Of course, for the defective products generated by the ball-adding and sleeve-combining, the defective products need to be discharged independently, and the flow does not need to be transferred to the next procedure. Therefore, the defective product discharging component is arranged on one side of the ball adding and sleeving mechanism 320, the defective product discharging component comprises a hollow leaking plate 331 and a discharging channel 332 arranged below the hollow leaking plate 331, and a material collecting groove 333 is arranged below the discharging channel 332. When the bearing with the ball sleeve is a defective product, the defective product can stay on the hollow leakage plate 331 after moving to the hollow leakage plate 331, and the defective product cannot stay on the hollow leakage plate 331 due to unstable gravity center, and falls into the discharging channel 332 from the hollow leakage position of the hollow leakage plate 331 and falls into the material collecting tank 333.

In conclusion, the ball adding and fitting device can select proper steel balls to perform ball adding and fitting operation according to the size of the bearing channel, and is high in universality.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
