Description

Technical Field

[0001] This invention relates to the field of bearing ring feeding technology, and in particular to an adaptive bearing ring feeding device. Background Technology

[0002] After stamping or casting, bearing rings generally require processes such as ring rolling, expansion, grinding, and polishing. When conveying bearing rings to the next process, conveyor belts are often used for transport or pushers are used for pushing.

[0003] For example, patent application publication number CN106743512B discloses a bearing ring feeding machine, including a frame and an inclined storage platform mounted on the frame. An inclined feeding channel is provided on one side of the storage platform. The lowest end of the feeding channel is hinged to the frame, and the highest end is provided with a driving device to change the inclination angle of the feeding channel. A pushing device is provided on the storage platform to push the bearing rings into the feeding channel. A ring-separating device is provided at the outlet of the feeding channel to realize the individual feeding of bearing rings. The appropriate inclination angle of the storage platform of this invention ensures that the bearing rings are neatly arranged. Individual feeding of bearing rings avoids collisions between them, reducing defective products caused by collisions and lowering production costs. The distance between a pair of feeding baffles in the feeding channel can be adjusted appropriately, making it suitable for feeding various types of bearing rings.

[0004] However, this method still has many drawbacks in practical use. For example, the bearing rings are basically in a horizontal position during the transmission process, moving forward with the conveyor belt or pusher. When they reach the next process step, they are still in a horizontal position, requiring manual or robotic arm lifting before clamping and processing, adding an extra step of adjusting the bearing ring position. To address these issues, we propose an adaptive bearing ring feeding device. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an adaptive bearing ring feeding device that can remove bearing rings that were originally in a horizontal position one by one, and can stand the originally horizontal bearing rings upright during the rotation of the feeding tray. Furthermore, the bearing rings fed by the feeding trays on the same vertical plane are all in the same straight line, so that the originally disordered bearing rings are stood up in a straight line, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bearing ring adaptive feeding device, comprising a rotating cylinder, wherein a plurality of feeding discs are distributed in an outer circumferential array on the rotating cylinder, and the feeding discs include a flow guiding component and an adjustment component installed outside the flow guiding component.

[0007] In a preferred embodiment, the flow guiding assembly includes a base plate, a ramp plate, and side baffles. The ramp plate is welded to the base plate to form a flow guiding plate. The end of the ramp plate away from the base plate is curved upward to form a hook-shaped part. The number of side baffles is set to two, and the two side baffles are symmetrically distributed on both sides of the flow guiding plate.

[0008] In a preferred embodiment, a flow guide groove is provided on one side of the base plate, and the inner sidewall of the side baffle is polished into a smooth arc surface by a grinding machine to form a flow guide edge.

[0009] In a preferred embodiment, the regulating assembly includes a clamshell baffle, an arc-shaped groove plate, a flow deflector, and an elastic connector. The number of clamshell baffles is set to two and symmetrically distributed on both sides. The two sides of the arc-shaped groove plate are fixedly connected to the two clamshell baffles respectively to form an regulating cavity. The flow deflector is provided inside the regulating cavity. The side wall of the flow deflector is fixedly connected to one side wall of the clamshell baffle through the elastic connector.

[0010] In a preferred embodiment, the ramp plate has a cavity formed in its slope, and an inclined deceleration plate is provided inside the cavity. Several spring groups are installed inside the cavity below the deceleration plate.

[0011] In a preferred embodiment, a plurality of speed reduction plates are equidistantly distributed along the edge of the surface of the speed reduction plate. The speed reduction plates are made of rubber material and the vertical cross-section of the speed reduction plates is set in a semi-circular shape.

[0012] In a preferred embodiment, the spring assembly includes a first spring and a second spring. The first spring is located below the higher end of the speed reduction plate and is fixedly connected to the end of the speed reduction plate. The second spring is located below the lower end of the speed reduction plate and is fixedly connected to the end of the speed reduction plate.

[0013] In a preferred embodiment, a buffer plate is installed inside the flow guide channel via a connecting shaft. A shaft receiving groove is opened on one side of the flow guide channel, and the shaft receiving groove is connected to the flow guide channel to form a cavity for accommodating the connecting shaft. The two side walls of the connecting shaft are respectively rotatably connected to the two inner side walls of the shaft receiving groove via the shaft. A fixing ring is welded to one end of the buffer plate, and the fixing ring is sleeved on the outside of the connecting shaft.

[0014] In a preferred embodiment, the number of the fixing ring blocks is set to at least one, and a coil spring is installed between the fixing ring block and the inner sidewall of the rotating shaft receiving groove. The coil spring is sleeved on the outside of the connecting rotating shaft, one end of the coil spring is fixedly connected to the sidewall of the fixing ring block, and the other end of the coil spring is fixedly connected to the inner sidewall of the rotating shaft receiving groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the overall structure designed in this invention, compared with the simple use of belt conveyors in the prior art, this application can remove the bearing rings that were originally in a horizontal position one by one, and can stand up the originally horizontal bearing rings during the rotation of the feeding plate. Furthermore, the bearing rings fed by the feeding plate on the same vertical plane are all in the same straight line, so that the originally messy bearing rings are stood up in a straight line, which facilitates subsequent processes such as ring rolling and polishing of the bearing rings.

[0017] 2. The spring assembly designed by this invention can absorb the impact generated when the bearing ring falls, thereby reducing the reaction force of the bearing ring itself and avoiding damage to the surface of the bearing ring during the feeding process. In addition, as the bearing ring rotates with the feeding plate, the elastic potential energy accumulated by the spring assembly will exert a pushing force on the bearing ring, making the bearing ring jump faster and improving the feeding efficiency.

[0018] 3. Through the cooperation and coordination between the buffer plate, the connecting shaft and the coil spring, the buffer plate not only supports the bearing rings, but also, when the bearing rings rotate with the feeding tray to the opposite direction, the buffer plate, driven by the coil spring, applies a pushing force to the bearing rings, making it easier for the bearing rings to roll out of the adjustment cavity, thereby increasing the feeding rate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] As attached Figure 1-7 The illustrated bearing ring adaptive feeding device includes a rotating cylinder 1, which is mounted on a frame. A drive wheel 2 is fixedly connected to the outer side of one end of the rotating cylinder 1. In this embodiment, an external servo motor output gear meshes with the drive wheel 2, driving the drive wheel 2 to rotate, which in turn drives the rotating cylinder 1 to rotate. Since the servo motor and the output gear are very common technologies in the field, they will not be described in detail in this embodiment. Several sets of feeding trays are distributed in a circular array on the outer side of the rotating cylinder 1. The feeding trays are fixed above the rotating cylinder 1 by a connecting plate 3. Each set of feeding trays consists of two trays. The feeding tray includes a flow guiding component 5 and an adjustment component 4 installed outside the flow guiding component 5. The flow guiding component 5 and the adjustment component 4 are combined to form a feeding tray that changes the bearing direction. There is a conveyor belt on one side of the feeding tray. The bearing rings are conveyed from the conveyor belt, usually in a horizontal state, and fall into the feeding tray, which is also in a horizontal state at this time. In the feeding tray, the horizontal state changes to a vertical state, and the rings rotate and roll out of the feeding tray for subsequent processing.

[0031] Reference Figure 4 The flow guiding component 5 in this embodiment will be described in detail. The flow guiding component 5 includes a base plate 51, a ramp plate 52, and a side baffle 53. The ramp plate 52 is welded to the base plate 51 to form a flow guiding plate. The end of the ramp plate 52 away from the base plate 51 is curved upward to form a hook-shaped part. The number of side baffles 53 is set to two, and the two side baffles 53 are symmetrically distributed on both sides of the flow guiding plate. When the feeding tray rotates to the bottom of the conveyor belt, the bearing ring will fall onto the surface of the ramp plate 52 due to the position of the hook-shaped part. At this time, the feeding tray continues to rotate, so that the bearing ring continues to move towards the base plate 51 under the action of gravity.

[0032] Reference Figure 4To further explain the flow guiding component 5 in this embodiment, a flow guiding groove 55 is provided on one side of the base plate 51. The inner sidewall of the side baffle 53 is polished into a smooth arc surface by a grinding machine to form a flow guiding edge 54. Therefore, as the bearing ring approaches the base plate 51, it may come into contact with the flow guiding edge 54 and be guided by the flow guiding edge 54, which plays a similar role as a limit. Therefore, the bearing ring will not deviate and will always be above the flow guiding plate. During the process of the feeding plate rotating and driving the flow guiding plate to rotate, the bearing ring will move from the inclined plate 52 to the base plate 51 and further move into the flow guiding groove 55, where it is limited by the flow guiding groove 55, thereby changing the bearing ring from a horizontal to a vertical state.

[0033] Reference Figure 3 The adjustment component 4 in this embodiment will be specifically described. The adjustment component 4 includes a clamshell baffle 41, an arc-shaped groove plate 42, a baffle plate 43, and an elastic connector 44. Two clamshell baffles 41 are symmetrically distributed on both sides. The two sides of the arc-shaped groove plate 42 are fixedly connected to the two clamshell baffles 41 respectively, forming an adjustment cavity. The fixing method can be welding or integral casting. The baffle plate 43 is provided inside the adjustment cavity. The side wall of the baffle plate 43 is welded to one side wall of the clamshell baffle 41 through the elastic connector 44. During the rotation of the feeding plate, the bearing ring first slides from the inclined plate 52 to above the bottom plate 51, and continues... As the feed tray continues to rotate, the bearing ring is thrown up by gravity. However, since one side of the bearing ring is in contact with the inner wall of the clamshell baffle 41 and the other side is in contact with the baffle plate 43, and the baffle plate 43 and the clamshell baffle 41 form a funnel shape, the bearing ring will squeeze the baffle plate 43 when it is thrown up and stands upright. The baffle plate 43 will also exert a force perpendicular to gravity on the bearing ring while being squeezed, causing the bearing ring to swing and roll into the regulating cavity from the funnel formed by the baffle plate 43 and the clamshell baffle 41. It will be squeezed by the tail of the baffle plate 43 and contact the inner wall of the arc-shaped groove plate 42, and will not be thrown out during rotation.

[0034] Reference Figure 5-6The structure of the ramp plate 52 in this embodiment will be further described. The ramp plate 52 has a cavity 6. An inclined deceleration plate 9 is installed inside the cavity 6. Several spring groups are installed inside the cavity 6 below the deceleration plate 9. When the bearing ring falls from the conveyor belt onto the deceleration plate 9, the bearing ring first contacts the end of the deceleration plate 9 at the higher end, causing the bearing ring to flip over during the fall. After all the bearing rings have fallen above the deceleration plate 9, the spring groups are compressed, thus accumulating elastic potential energy. Because the deceleration plate 9 is inclined, the bearing rings will not be thrown out from the hook-shaped part. Instead, they will slide down continuously under the action of gravity during the rotation of the feeding plate, sliding onto the bottom plate 51. After the feeding plate rotates to a certain extent, the elastic potential energy accumulated by the spring groups is released, causing the deceleration plate 9 to reset and the bearing rings sliding into the bottom plate 51 at a certain speed.

[0035] Reference Figure 5-6 In this embodiment, several speed reduction plates are evenly distributed along the edge of the surface of the speed reduction plate 9. The speed reduction plates are made of rubber material and the vertical cross section of the speed reduction plate is set as a semi-circle, thereby effectively absorbing the impact force when the bearing ring falls, reducing the reverse impact force on the bearing ring, avoiding wear of the bearing ring, and also slowing down the process of the bearing ring sliding towards the base plate 51, preventing the bearing ring from moving too fast.

[0036] Reference Figure 6 The spring assembly in this embodiment is described in detail below. The spring assembly includes a first spring 7 and a second spring 8. The elastic coefficient of the first spring 7 is smaller than that of the second spring 8. When the bearing ring is above the deceleration plate 9, it will press the deceleration plate 9 into an approximately horizontal state. The first spring 7 is located below the higher end of the deceleration plate 9 and is fixedly connected to the end of the deceleration plate 9. The second spring 8 is located below the lower end of the deceleration plate 9 and is fixedly connected to the end of the deceleration plate 9. During the rotation of the feeding tray, the elastic potential energy in the spring assembly will be released, thereby giving the deceleration plate 9 a force. The deceleration plate 9 resets, which is equivalent to pushing the bearing ring up. Because the elastic potential energy of the first spring 7 is greater, the speed of the bearing ring away from the bottom plate 51 is greater than the speed of the bearing ring near the bottom plate 51, thereby causing the bearing ring to jump up. Combined with the rotation of the feeding tray, the speed at which the bearing ring goes from "lying down" to "standing up" is faster.

[0037] Reference Figure 7The buffer plate 10 in this embodiment is described in detail. The buffer plate 10 is installed inside the flow channel 55 through the connecting shaft 12. A shaft receiving groove 11 is opened on one side of the flow channel 55. The shaft receiving groove 11 is connected to the flow channel 55 to form a cavity for accommodating the connecting shaft 12. The two side walls of the connecting shaft 12 are respectively rotatably connected to the two inner side walls of the shaft receiving groove 11 through the shaft. A fixing ring block 13 is welded to one end of the buffer plate 10. The fixing ring block 13 is sleeved on the outside of the connecting shaft 12. The number of fixing ring blocks 13 is set to at least one. A coil spring 14 is installed between the fixing ring block 13 and the inner side wall of the shaft receiving groove 11. The coil spring 14 is sleeved on the outside of the connecting shaft 12. One end of the coil spring 14 is fixedly connected to the side wall of the fixing ring block 13, and the other end of the coil spring 14 is fixedly connected to the inner side wall of the shaft receiving groove 11.

[0038] When the bearing ring enters the adjustment chamber in the "standing up" position, it is still rolling inside the adjustment chamber until the side wall of the bearing ring rolls to contact the buffer plate 10. Due to the weight of the bearing ring, the buffer plate 10 will be squeezed, causing the buffer plate 10 to rotate under the cooperation of the connecting shaft 12 and the fixed ring block 13. At this time, the bearing ring is stuck in the guide groove 55 and fixed in the "standing up" position. As the feeding plate continues to rotate, the overall structure begins to reverse. At this time, the outer side wall of the bearing ring contacts the inner side wall of the arc-shaped groove plate 42. At this time, the arc-shaped groove plate 42 is equivalent to the bearing ring's bearing plate.

[0039] As the feeding tray continues to rotate, the buffer plate 10 no longer supports the bearing rings. Instead, it tries to reset under the action of the coil spring 14, thus generating a pushing force on the bearing rings, causing the bearing to roll outward along the adjustment cavity. Since the clamshell baffle 41 and the arc groove plate 42 in the adjustment cavity form a shape similar to a trumpet, the bearing rings move outward more and more easily until they completely leave the range of the arc groove plate 42 and are no longer supported by it. At this point, the feeding process of automatically adjusting the position of the bearing rings is completed, and the bearing rings that were originally horizontal or vertical are all now in a vertical position. The position of the bearing rings as they roll out is fixed and they are all in a straight line, which facilitates other processes on the bearing rings.
