Referring to fig. 1 to 7, a rapid ball press-fitting machine according to an embodiment includes a frame 1, a press-fitting device 2, and a ball loading device 3, which can automatically align a ball with a ball socket hole, and continuously press-fit the ball onto a retainer, thereby improving the press-fitting efficiency of the ball device.

Specifically, referring to fig. 1 to 3, the press-fitting device 2 includes a press-fitting roller 21, a distribution block 22, and a holder feeding mechanism 23. The number of the press-fitting rollers 21 is two, the two press-fitting rollers 21 are arranged on the frame 1 side by side up and down, and a press-fitting gap 211 is arranged between the two press-fitting rollers 21. The two press-fitting rollers 21 are arranged at intervals up and down, and the gap between the two press-fitting rollers 21 is a press-fitting gap 211. The press-fitting roller 21 is used to press the steel balls 52 placed in the openings of the ball holes 511 into the ball holes 511. During press fitting, the retainer 51 is inserted into and passes through the press fitting gap 211, the press fitting roller 21 is driven to rotate by a driving device such as a motor, and the press fitting roller 21 presses the steel balls 52 and the retainer 51 to press the steel balls 52 into the ball hole 511. The roller of the press-fitting roller 21 may be made of plastic or rubber to protect the steel balls 52 and the holder 31. In one embodiment, the two press-fitting rollers 21 are vertically spaced from each other.

The distribution block 22 is disposed on one side of the two press-fitting rollers 21. The distributing block 22 is provided with a steel ball feeding hole 221 extending downwards, and the steel ball feeding hole 221 penetrates through the bottom surface of the distributing block 22 downwards. The upper end of the steel ball feeding hole 221 is connected with the steel ball feeding device 3, and a limiting opening 222 is arranged at the orifice of the lower end of the steel ball feeding hole 221. The limiting opening 222 is arranged on the side wall of the steel ball feeding hole 221 close to one side of the press-fitting roller 21. Specifically, the distribution block 22 is disposed on one side of the two press-fitting rollers 21 in the horizontal direction. The high and low positions of the distribution block 22 are arranged in cooperation with the press-fitting gap 211, and the limiting opening 222 faces the press-fitting gap 211. In one embodiment, the ball feed hole 221 is vertically disposed, and the limiting opening 222 horizontally faces the press-fitting gap 211.

The holder feeding mechanism 23 is provided with a straight feeding groove 2321. An opening at one end of the feeding groove 2321 is arranged right opposite to the press-fitting gap 211, and the retainer feeding mechanism 23 can enable the retainer 51 to pass through the position right below the steel ball feeding hole 221 and enter the press-fitting gap 211 along the feeding groove 2321. The steel balls 52 in the steel ball feeding holes 221 are supported on the upper surface of the retainer 51, so that the steel balls 52 can be limited in the steel ball feeding holes 221, the steel balls 52 in the steel ball feeding holes 221 fall into the upper ball socket holes 511 of the retainer 51, and the corresponding steel balls 52 can pass through the limiting openings 222. Specifically, the feed chute 2321 has a cross-sectional shape corresponding to the holder 51. The chute 2321 is positioned to be disposed below the distributor block 22 in cooperation with the distributor block 22. When the retainer 51 is conveyed, the shape defined by the upper surface of the retainer 51 and the limiting opening 222 can prevent the steel balls 52 from passing through, so that the steel balls 52 are limited in the steel ball feeding hole 221. When the steel balls 52 fall into the upper ball hole 511 of the retainer 51, the distance from the tops of the steel balls 52 to the upper surface of the retainer 51 is reduced, so that the steel balls 52 can move with the retainer 51 through the stopper hole 222. In one embodiment, the feeding slot 2321 is horizontally disposed, and one end of the feeding slot 2321 horizontally faces the press-fitting gap 211. The limiting opening 222 is in an inverted U shape, the limiting opening 222 is arranged in parallel with the conveying direction of the retainer 51, and the diameter of the inverted U-shaped top of the limiting opening 222 is larger than that of the steel ball 52. The distance from the uppermost position of the inverted U-shaped top of the limiting opening 222 to the upper surface of the conveyed retainer 51 is smaller than the diameter of the steel ball 52 and larger than the distance from the top of the steel ball 52 to the upper surface of the retainer 51 when the steel ball 52 falls into the ball hole 511 on the retainer 51. It is understood that the shape of the restraint opening 222 may be rectangular, arcuate, or any other shape. As long as the steel balls 52 are supported by the upper surface of the retainer 51, the steel balls 52 cannot pass through the limiting openings 222; the steel ball 52 falls into the ball socket hole 511, so that the position of the steel ball 52 can pass through the limiting opening 222 after being lowered.

When the ball press-fitting device is used, the steel balls 52 are continuously conveyed into the steel ball feeding hole 221 by the steel ball feeding device 3, the retainer feeding mechanism 23 conveys the retainer 51 into the press-fitting gap 211 from the lower part in the steel ball feeding hole 221, and when the ball socket hole 511 on the retainer 51 passes through the steel ball feeding hole 221, the steel balls 52 at the bottom of the steel ball feeding hole 221 fall into the hole of the ball socket hole 511, so that the steel balls 52 enter the press-fitting gap 211 along with the retainer 51 through the limiting hole 222 to complete press-fitting; the ball device rapid press-fitting machine automatically aligns the steel balls 52 with the ball socket holes 511, and continuously press-fits the steel balls 52 onto the retainer 51, thereby improving the press-fitting efficiency of the ball device 5.

In one embodiment, the holder feeding mechanism 23 includes a feed roller 231 and a loading frame 232. The loading frame 232 is arranged on the side of the distributor block 22 facing away from the press-fitting roller 21. The feeding groove 2321 is arranged on the feeding frame 232, and the feeding roller 231 is arranged in cooperation with the feeding groove 2321. The feed roller 231 rotates to drive the holder 51 to move along the feed groove 2321 and along the feed groove 2321 into the press-fitting gap 211. Specifically, the feed chute 2321 is disposed in cooperation with the ball feed hole 221 to ensure that the cage 51 can pass directly below the ball feed hole 221. It is understood that the holder feeding mechanism 23 may also be configured to provide the feeding chute 2321 on the conveyor belt, or to fit the partition through the conveyor belt or the feeding roller. It is sufficient that the holder 51 can be fed into the press-fitting gap 211 straight.

In one embodiment, the dispenser block 22 further includes a guide groove 223. The guide groove 223 is arranged in parallel with the feed groove 2321, one end of the guide groove 223 is connected with the limit opening 222, and the other end of the guide groove 223 extends to the press-fitting roller 21 positioned above. The cross section of the guide groove 223 is arranged in the same shape as the stopper hole 222. The guide groove 223 restrains the steel ball 52 in the opening of the ball hole 511 to prevent the steel ball 52 from coming out of the ball hole 511 when it is pressed by the press-fitting roller 21.

Referring to fig. 2, 4 and 5, the ball feeder 3 includes a hopper 31, a feeding tube 33, a support plate 34 and a linkage rocker 35. The hopper 31 is located above the dispenser block 22, remote from the dispenser block 22. The feeding pipe 33 is composed of a spiral spring, one end of the feeding pipe 33 is connected with the bottom of the hopper 31, the other end of the feeding pipe 33 is connected with the upper end of the steel ball feeding hole 221, and the feeding pipe 33 is tensioned vertically. Specifically, two ends of the feeding pipe 33 are respectively connected with the hopper 31 and the connecting block 36 and then tensioned, so that the feeding pipe 33 with a spiral spring structure is in an original length or stretching state. The inner diameter of the coil spring structure of the feed pipe 33 is set in accordance with the diameter of the steel balls 52 to align the steel balls 52. The inner diameter of the coil spring structure is larger than the diameter of the steel ball 52 and smaller than twice the diameter of the steel ball 52. The spring wires of the coil springs should be spaced apart a distance less than the diameter of the steel ball 52. The bottom of the hopper 31 is provided with a shutter plate 32 for controlling the opening and closing of the hopper 31 and the feed pipe 33. The shutter plate 32 is slidably inserted on the hopper 31. The supporting plate 34 is sleeved on the middle part of the feeding pipe 33 and is arranged on the rack 1 in a sliding way. Specifically, the sliding direction of the support plate 34 is arranged to intersect with the extension direction of the feeding pipe 33. The support plate 34 slides so that the position of the middle portion of the feeding tube 33 varies with the support plate 34. Because the two ends of the feeding pipe 33 are respectively connected with the hopper 31 and the upper end of the steel ball feeding hole 221 and then tensioned, the length of the feeding pipe 33 can be increased by the sliding of the supporting plate 34, and the feeding pipe 33 has the tendency of shrinking under the action of elastic restoring force. In one embodiment, the sliding direction of the support plate 34 is horizontally disposed. The shutter plate 32 is always in a state of blocking the hopper 31 from the feed pipe 33. The middle part of the linkage rocker 35 is rotatably arranged on the frame 1, and two ends of the linkage rocker 35 are respectively in transmission connection with the gate plate 32 and the support plate 34. The press-fitting roller 21 is in transmission connection with the linkage rocker 35. The press-fitting roller 21 rotates to enable the linkage rocker 35 to swing in a reciprocating mode, the gate plate 32 slides to communicate the hopper 31 with the feeding pipe 33, and the supporting plate 34 slides to drive the middle of the feeding pipe 33 to enable the feeding pipe 33 to extend; or the gate plate 32 is reset by sliding to block the hopper 31 from the feeding pipe 33. Specifically, in the process of swinging and rotating the linkage rocker 35, the shutter plate 32 and the support plate 34 are provided with: a first state that the gate plate 32 enables the hopper 31 to be communicated with the feeding pipe 33, and the supporting plate 34 slides to drive the middle part of the feeding pipe 33 to extend the feeding pipe 33; and a second state in which the shutter plate 32 is slidably restored to block the hopper 31 from the feed pipe 33. When the linkage rocker 35 continuously swings back and forth, the gate plate 32 and the support plate 34 are jointly circulated between the first state and the second state. When the press-fitting roller 21 rotates to make the linkage rocker 35 perform reciprocating swing rotation and drive the gate plate 32 to slide to make the hopper 31 communicate with the feeding pipe 33, the supporting plate 34 slides to extend the feeding pipe 33 formed by a spiral spring, so that the steel balls 52 enter the feeding pipe 33. Then, the linkage rocker 35 is rotated reversely to drive the gate plate 32 to slide and reset, so that the hopper 31 is blocked from the feeding pipe 33. Because the steel balls 52 support and block the feeding pipe 33 in the feeding pipe 33, the feeding pipe 33 can not be completely retracted in the sliding and resetting process of the gate plate 32, so that after the gate plate 32 is reset, the feeding pipe 33 generates pressure along the conveying direction on the steel balls 52 under the action of elastic restoring force, the clamping stagnation of the steel balls 52 during conveying is avoided, and the missing of the steel balls 52 is prevented.

In one embodiment, the rotation axis of the linkage rocker 35 rotatably connected with the frame 1 is perpendicular to the rotation axis of the press-fitting roller 21. A cantilever rod 353 is arranged in the middle of the linkage rocker 35, one end of the cantilever rod 353 is fixedly connected with the middle of the linkage rocker 35, and the other end of the cantilever rod 353 extends in a direction away from the linkage rocker 35, so that the cantilever rod 353 and the linkage rocker 35 form a T shape. The quick press-mounting machine for the ball devices further comprises a transmission connecting rod 4 and a crank piece 42, wherein the crank piece 42 is rotatably arranged on the machine frame 1, a rotating shaft of the crank piece 42 is parallel to a rotating shaft of the press-mounting roller 21 and is in transmission arrangement with the press-mounting roller 21, and two ends of the transmission connecting rod 4 are respectively connected with the crank piece 42 and the cantilever rod 353, so that the crank piece 42, the transmission connecting rod 4 and the linkage rocker 35 form a spatial crank-rocker mechanism. Specifically, the two ends of the transmission link 4 are respectively provided with a knuckle bearing 41 (knuckle bearing is also called fisheye joint). Two ends of the transmission connecting rod 4 are respectively in ball joint with the crank piece 42 and the linkage rocker 35 through joint bearings 41. So as to simplify the transmission structure between the press-fitting roller 21 and the linkage rocker 35. It is understood that the press-fitting roller 21 and the linkage rocker 35 can be in transmission connection through other structures in the prior art.

In one embodiment, the linking rocker 35 has a pushing portion 351 at an end thereof away from the shutter plate 32. The linkage rocker 35 can rotate, the gate plate 32 slides to communicate the hopper 31 with the feeding pipe 33, and the support plate 34 slides to drive the middle part of the feeding pipe 33, so that the feeding pipe 33 extends. Or the shutter plate 32 is slid and reset to block the hopper 31 from the feeding pipe 33, and the pushing part 351 is separated from the supporting plate 34. Specifically, the pushing portion 351 is a roller disposed on the linking rocker 35. The linkage rocker 35 pushes the support plate 34 to move through the pushing part 351, so that the feeding pipe 33 extends.
