Description
Technical Field
The invention relates to the technical field of ball separation, in particular to bearing ball ejecting equipment.
Background
The bearing is a very important part in mechanical equipment, and the ball is a core part of the bearing. As shown in fig. 1 and 2, the bearing 10 includes an inner race 101, an outer race 102, balls 103, and ball retainers 104. A ball retainer 104, which is provided with balls, is interposed between the inner ring 101 and the outer ring 102. Before the ball 103 is mounted on the ball retainer 104, the ball 103 is usually coated with a lubricant to reduce the friction coefficient of the ball 103. When the balls 103 are mounted on the ball retainer 104, the balls 103 need to be individually held in the ball retainer grooves 105 of the ball retainer 104.
However, the ball 103 is usually a round solid steel ball, which not only has the characteristics of spherical structure, small volume and high density, but also has a layer of lubricant coated on the surface to make the surface of the ball 103 especially smooth. In addition, the balls 103 coated with a layer of lubricant have certain viscosity, so that the separation difficulty is high.
In the prior art, the ball 103 is separated manually by hand, so that the ball 103 is easy to slip off from the hand when the ball 103 is separated manually. Therefore, the manual separation of the balls 103 by hands is extremely inefficient and labor cost is high.
In the prior art, there is a method of separating the ball 103 by using an auxiliary tool, such as a clamp or the like. However, since the ball 103 has a spherical structure, a small volume and a large density, and a layer of lubricant is coated on the surface of the ball 103 to make the surface of the ball 103 very smooth, the efficiency is not high even if an auxiliary tool is used to separate the ball 103, and the problem that the ball 103 slips cannot be completely avoided. Therefore, there is a need for an apparatus that can separate the balls 103 one by one with high efficiency.

As shown in fig. 3, the present invention provides a bearing ball ejecting apparatus 20 for efficiently ejecting balls 200 one by one and rapidly separating the balls 200, in view of the above problems of the prior art.

The ball receptacle 220 is opened with a ball drop opening 223.
As shown in fig. 3, the ball ejecting mechanism 230 includes a ball transmission pipe 231, a ball ejecting body 232, and a ball ejecting control unit 233.
As shown in fig. 3 and 4, the ball ejecting body 232 has a ball aligning passage 232A formed therein to penetrate the ball ejecting body 232, and an inner diameter of the ball aligning passage 232A is larger than a diameter of the ball 200 and smaller than twice the diameter of the ball 200. The ball aligning passage 232A communicates with the ball transfer pipe 231, the ball transfer pipe 231 communicates with the ball drop opening 223, and the ball ejection control unit 233 is provided on the ball ejection body 232.
As shown in fig. 4 and 5, the ball ejection control assembly 233 includes a pressing rod 234, a movable rod 235 and a return elastic member 236. One end of the pressing rod 234 is hinged to the movable rod 235, the other end is hinged to the ball ejecting body 232, and the return elastic member 236 is disposed on the ball ejecting body 232. The return spring 236 provides a return spring force to the hold-down bar 234 such that the hold-down bar 234 acquires a tendency to move away toward the ball ejection body 232. The movable rod 235 is slidably disposed on the ball ejecting body 232. The movable rod 235 is provided with a first ball blocking piece 235A and a second ball blocking piece 235B, the first ball blocking piece 235A and the second ball blocking piece 235B are elastic blocking pieces, and the first ball blocking piece 235A and the second ball blocking piece 235B are parallel to each other and have a spacing distance smaller than the diameter of the ball 200. The first ball stopper piece 235A and the second ball stopper piece 235B form a blocking and ejecting dislocation at the ball alignment passage 232A, thereby blocking or ejecting the balls 200 in the ball alignment passage 232A one by one.
As shown in fig. 3, the hanging device 22 is a cone-shaped frame body 221, and a hook 222 is provided on the top of the frame body for fixing the frame body at a high position, thereby fixing the ball ejector 21 at the high position and suspending the ball ejector 21.

The stirring assembly 211 comprises a stirring head 213 and a connecting rod 214, and the stirring head 213 is connected with the driving assembly 212 through the connecting rod 214. The driving unit 212 is fixed to the bottom of the suspension unit 22, and the stirring unit 211 extends into the ball receptacle 220 from the bottom of the suspension unit 22.
As shown in fig. 3, the ball receptacle 220 is opened with a ball drop opening 223. In one preferred embodiment, the ball receptacle 220 has a funnel shape, and the ball drop opening 223 is opened at the narrowest portion of the funnel shape.
As shown in fig. 3, as one preferred embodiment, the stirring head 213 protrudes into the lower end of the ball receptacle 220, that is, the stirring head 213 protrudes into the vicinity of the ball drop opening 223.
As shown in fig. 3 and 4, during the separation of the balls 200, the driving assembly 212 drives the stirring assembly 211 to rotate, so that the stirring head 213 rotates near the ball dropping opening 223, thereby stirring the balls 200 near the ball dropping opening 223, so that the balls 200 near the ball dropping opening 223 roll and orderly drop from the ball dropping opening 223.
As shown in fig. 4, a ball aligning passage 232A is formed in the ball ejecting body 232 to penetrate the ball ejecting body 232, and an inner diameter of the ball aligning passage 232A is larger than a diameter of the ball 200 and smaller than twice the diameter of the ball 200. The ball aligning passage 232A communicates with the ball transfer duct 231, and the ball transfer duct 231 communicates with the ball drop port 223. The balls falling from the ball drop port 223 enter the ball queue passage 232A through the ball transfer duct 231, and the balls 200 entering the ball queue passage 232A are arranged one by one.
As shown in fig. 3 and 4, the ball ejection control assembly 233 includes a pressing rod 234, a movable rod 235 and a return elastic member 236. One end of the pressing rod 234 is hinged to the movable rod 235, the other end is hinged to the ball ejecting body 232, and the return elastic member 236 is disposed on the ball ejecting body 232. The return spring 236 provides a return spring force to the hold-down bar 234 such that the hold-down bar 234 acquires a tendency to move away toward the ball ejection body 232. In one preferred embodiment, the return elastic member 236 is a spring structure. Of course, in other embodiments, the elastic restoring member 236 may be an elastic plastic member. The return spring 236 may also be made of other materials or structures having a spring return characteristic.
As shown in fig. 5 and 6, as a preferred embodiment, the first ball stopper 235A is shorter than the second ball stopper 235B, and the second ball stopper 235B is opened with a ball drop hole 235C.
As shown in fig. 4 and 5, when no external force is applied to the pressing rod 234, the elastic force provided by the restoring elastic member 236 indirectly restores the movable rod 235, so that the first ball blocking piece 235A is separated from the ball aligning passage 232A, and the second ball blocking piece 235B is blocked by the ball aligning passage 232A, thereby blocking the balls 200. At this time, the balls 200 in the ball aligning passage 232A farthest from the ball drop hole 235C drop onto the second ball stopper 235B, and the other balls 200 in the ball aligning passage 232A are arranged next to the balls 200 in the ball aligning passage 232A farthest from the ball drop hole 235C and in order.
As shown in fig. 4 and 5, when an external force is applied to the pressing rod 234, the movable rod 235 slides in a direction approaching the ball aligning passage 232A, so that the first ball stopper 235A enters the ball aligning passage 232A and is stopped by the ball aligning passage 232A, and the ball falling hole 235C of the second ball stopper 235B is communicated with the ball aligning passage 232A. In the process that the first ball stopper piece 235A enters the ball queuing channel 232A, the first ball stopper piece 235A separates the ball 200 farthest from the ball drop hole 235C in the ball queuing channel 232A from the other balls 200 in the ball queuing channel 232A, and the ball 200 farthest from the ball drop hole 235C in the ball queuing channel 232A is ejected separately, thereby realizing the ejection of the single ball 200. Therefore, the pressing rod 234 realizes the ball ejection one by one during the interleaving action of the restoring elastic force and the external force, thereby realizing the rapid ball separation.
Referring to fig. 4-6, as a preferred embodiment, the first ball stopper 235A and the second ball stopper 235B are elastic stoppers, and the first ball stopper 235A and the second ball stopper 235B are parallel to each other and spaced apart by a distance smaller than the diameter of the balls 200. The above-mentioned structural design makes the ball 200 between the first ball stopper 235A and the second ball stopper 235B, the first ball stopper 235A and the second ball stopper 235B deform. When the first ball stopper 235A enters the ball queuing passage 232A and is stopped in the ball queuing passage 232A and the ball drop hole 235C of the second ball stopper 235B is communicated with the ball queuing passage 232A, the balls 200 between the first ball stopper 235A and the second ball stopper 235B are simultaneously subjected to their own gravity and pressure by the first ball stopper 235A, thereby rapidly ejecting the ball queuing passage 232A.
As shown in fig. 4 and 5, as a preferred embodiment, the ball ejecting body 232 is provided with a ball orienting channel 232B at an end away from the ball conveying pipe 231, and the ball orienting channel 232B is communicated with the ball aligning channel 232A. The ball is ejected out of the ball aligning passage 232A and then enters the ball orienting passage 232B, and the ball 200 is oriented in the running direction by the ball orienting passage 232B, so that the moving direction of the ball 200 is stabilized when the ball is ejected out of the ball ejecting body 232. Thereby facilitating access to and use of the separated balls 200. If the ball 200 ejecting the ball ejecting body 232 is not oriented, the direction of the ball 200 ejecting the ball ejecting body 232 is uncertain, and the ball 200 which runs fast and has an uncertain direction is difficult to obtain and use.
As shown in fig. 5, as a preferred embodiment, the ball ejecting body 232 is formed with a first sliding groove 232C and a second sliding groove 232D respectively engaged with the first ball stopper 235A and the second ball stopper 235B. The sliding directions of the first ball blocking piece 235A and the second ball blocking piece 235B are limited respectively through the first sliding groove 232C and the second sliding groove 232D, so that the first ball blocking piece 235A and the second ball blocking piece 235B stably pop up the balls 200 in the ball queue passage 232A one by one.
As shown in fig. 5, as one preferred embodiment, the ball ejecting body 232 is formed with a third sliding groove 232E engaged with the movable rod 235. The sliding direction of the movable rod 235 is limited through the third sliding groove 232E, so that the sliding direction of the first ball blocking piece 235A and the second ball blocking piece 235B is indirectly stable, and the first ball blocking piece 235A and the second ball blocking piece 235B are further ensured to stably pop up the balls 200 in the ball queue passage 232A one by one.
As shown in fig. 3, the ball transfer pipe 231 is an elastic bellows hose as one preferred embodiment. In the application process, the ball transmission pipeline 231 can be stretched or bent according to actual needs, so that the adaptive adjustment of the ejection position and the ejection direction of the ball 200 is realized, and the application of the bearing ball ejection device 20 is more flexible and convenient.
As shown in fig. 3 and 4, as a preferred embodiment, the pressing rod 234 is provided with a plurality of concave-convex staggered circular arc sections 234A, and the plurality of concave-convex staggered circular arc sections 234A form the wavy structure. The pressing and holding rod 234 is provided with a wave-shaped structure similar to the radian of a finger, so that the pressing and holding rod 234 is not easy to slip when being held by hand and external force is applied to the pressing and holding rod 234, and the operation hand feeling is good.
As shown in fig. 4, during the separation of the balls 200, the balls 200 are coated with a layer of lubricant, so that the balls 200 have a certain viscosity with respect to each other and are easily stuck to the ball aligning passage 232A.
As shown in fig. 4 and 7, in order to solve the above problem, the ball ejecting body 232 is further provided with a ball adjustment assembly 237. The ball adjustment assembly 237 includes a return spring structure 238 and a ball adjustment structure 239. The ball adjusting structure 239 is fixed on the outer wall of the ball ejecting body 232 through the elastic restoring structure 238. Ball adjustment structure 239 extends from the outer wall of ball ejecting body 232 into ball queue channel 232A. The return spring structure 238 provides a spring force to the ball adjustment structure 239 such that the ball adjustment structure 239 gains a tendency to move away from the ball alignment passage 232A.
As shown in fig. 4 and 7, when no external force is applied to the ball adjustment structure 239, the ball adjustment structure 239 is restored by the elastic force of the restoring elastic structure 238 and is separated from the ball queue passage 232A.
As shown in fig. 4 and 7, when an external force is applied to the ball adjustment structure 239, the ball adjustment structure 239 extends into the ball alignment passage 232A under the external force. By applying an external force to the ball adjusting structure 239, the ball adjusting structure 239 acts on the balls 200 in the ball queue passage 232A, so that the balls 200 in the ball queue passage 232A fall normally without being stuck in the ball queue passage 232A.
As shown in fig. 7, as one preferred embodiment, the return spring structure 238 is a spring structure.
As shown in fig. 7, as one preferred embodiment, the ball adjustment structure 239 includes a connecting portion 239A, and a force-receiving portion 239B and a ball adjustment portion 239C respectively disposed at two ends of the connecting portion 239A. The connecting portion 239A is connected to the elastic return structure 238, the ball adjustment portion 239C is separated from or extends into the ball alignment passage 232A, and the force receiving portion 239B is used for receiving an external force.
As shown in fig. 4 and 7, when the force-receiving portion 239B receives an external force, the ball adjusting structure 239 moves toward the ball aligning passage 232A, so that the ball adjusting portion 239C extends into the ball aligning passage 232A.
As shown in fig. 4 and 7, when the external force is stopped being applied to the force receiving portion 239B, the ball adjusting structure 239 moves away from the ball queue passage 232A under the restoring elastic force of the restoring elastic structure 238, so that the ball adjusting portion 239C is separated from the ball queue passage 232A.
The working principle of the bearing ball ejecting apparatus 20 of the present invention is as follows:
the suspension device 22 fixes the ball ejecting device 21 in a suspension manner;
the balls to be separated are received in the ball receivers 220;
the ball stirring mechanism 210 stirs the balls 200 in the ball container 220 so that the balls 200 in the ball container 220 fall from the ball falling port 223 of the ball container 220;
the balls 200 fall from the ball falling port 223 and pass through the ball transfer duct 231 and then sequentially enter the ball queuing passage 232A, and are arranged in the ball queuing passage 232A in a single longitudinal direction;
when no external force is applied to the pressing rod 234, the elastic force provided by the reset elastic member 236 indirectly resets the movable rod 235, so that the first ball blocking piece 235A is separated from the ball queuing channel 232A, and the second ball blocking piece 235B is blocked in the ball queuing channel 232A, thereby blocking the balls 200; at this time, the balls 200 in the ball aligning passage 232A farthest from the ball drop hole 235C drop onto the second ball stopper 235B, and the other balls 200 in the ball aligning passage 232A follow the balls 200 in the ball aligning passage 232A farthest from the ball drop hole 235C and are sequentially arranged;
when an external force is applied to the pressing rod 234, the movable rod 235 slides in a direction close to the ball aligning passage 232A, so that the first ball blocking piece 235A enters the ball aligning passage 232A and is blocked in the ball aligning passage 232A, and the ball falling hole 235C of the second ball blocking piece 235B is communicated with the ball aligning passage 232A; in the process that the first ball stopper piece 235A enters the ball queuing channel 232A, the first ball stopper piece 235A separates the ball 200 farthest from the ball drop hole 235C in the ball queuing channel 232A from other balls 200 in the ball queuing channel 232A, and the ball 200 farthest from the ball drop hole 235C in the ball queuing channel 232A is ejected separately, thereby realizing the ejection of a single ball 200;
the first ball blocking piece 235A and the second ball blocking piece 235B are elastic blocking pieces, and the first ball blocking piece 235A and the second ball blocking piece 235B are parallel to each other and have a spacing distance smaller than the diameter of the ball 200; the above structure design makes the first ball stopper 235A and the second ball stopper 235B deform when the ball 200 is between the first ball stopper 235A and the second ball stopper 235B; when the first ball stopper 235A enters the ball queuing passage 232A and is stopped in the ball queuing passage 232A and the ball falling hole 235C of the second ball stopper 235B is communicated with the ball queuing passage 232A, the balls 200 between the first ball stopper 235A and the second ball stopper 235B are simultaneously subjected to the action of their own gravity and the pressure of the first ball stopper 235A on them, thereby rapidly ejecting the ball queuing passage 232A;
the pressing rod 234 realizes the one-by-one ejection of the balls 200 in the process of the alternating action of the return elastic force and the external force, thereby realizing the rapid separation of the balls 200.
