Description

Technical Field

[0001] This invention relates to the field of ball bearing sorting technology, and more specifically, to a ball bearing sorting device and its usage method for bearing production. Background Technology

[0002] Ball bearing sorting refers to the screening and grading of balls using mechanical equipment to achieve classification and sorting purposes. Ball bearing sorting is widely used in machinery manufacturing, automobile manufacturing, aerospace, electronics, and communications. The principle of ball bearing sorting is to utilize the gravity and inertia of the balls themselves, and through the vibration and rotation of the sorting equipment, to cause balls of different sizes to enter different sieve holes or grading tanks, thus achieving the purpose of classification and sorting.

[0003] In existing bearing production ball sorting equipment, the machine arranges the balls onto a screening step so that they fall into different screen holes according to their size for grading. However, some larger balls get stuck in smaller screen holes, causing subsequent balls to also get stuck and unable to move, rendering the entire sorting device unusable. Therefore, how to design a bearing production ball sorting device and its usage method that can prevent balls from getting stuck in the screen holes has become the problem we need to solve. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a ball bearing sorting device and its usage method for bearing production. By setting up a movable rotating plate and a pusher plate, during ball sorting, the transmission roller drives the movable rotating plate to move the movable pusher column, ultimately causing the movable plate to drive the pusher plate to move obliquely, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a ball bearing sorting device for bearing production, comprising a feed pipe, a sorting turntable, and a feeding pipe. The sorting turntable is connected to the bottom of the feed pipe, and the feeding pipe is connected to one side of the sorting turntable. A screening step is fixedly connected to one side of the feeding pipe. A drive roller is rotatably connected to the inner wall of the sorting turntable, and a rotating plate is fixedly connected to the outer wall of the drive roller. A rotary motor is rotatably connected to one end of the drive roller, and a fixed plate is connected to the end of the drive roller away from the rotary motor. A movable rotating plate has a movable push column fixedly connected to one side. A push bar is hinged to the outer wall of the movable push column. A first support shaft is hinged to one side of the push bar. A movable plate is hinged to the outer wall of the first support shaft. A pusher plate is fixedly connected to the bottom of the movable plate. A second support shaft is hinged to the top of the movable plate. A movable bar is hinged to the outer wall of the second support shaft. A third support shaft is hinged to the outer wall of the movable bar. A support frame is hinged to the outer wall of the third support shaft. The support frame is fixedly connected to the outer wall of the sorting turntable.

[0006] By adopting the above technical solution, during the sorting of balls, the transmission roller drives the movable rotating plate to move the movable push column, which in turn drives the push bar to move. The push bar then moves the movable plate via the first support shaft. As the movable plate moves, it moves obliquely via the movable bar, which in turn drives the push plate to move. The push plate then pushes the balls on the screening steps, preventing the balls from getting stuck in the screen holes. This solves the problem of balls getting stuck in the screen holes, which prevents subsequent balls from moving and renders the entire sorting device unusable.

[0007] In a preferred embodiment, an oil storage tank is fixedly connected to one side of the sorting turntable, and an oil drain pipe is connected to one side of the oil storage tank, which is connected to the outer wall of the feed pipe.

[0008] By adopting the above technical solution, workers can drain the lubricating oil from the oil storage tank into the feed pipe through the drain pipe. The lubricating oil will lubricate and protect the balls, preventing them from being damaged due to excessive friction during transportation.

[0009] In a preferred embodiment, a movable component is sleeved on the outer wall of the movable push column, a piston rod is fixedly connected to one side of the movable component, a piston plate is fixedly connected to one end of the piston rod, and the piston plate is slidably connected to the inner wall of the oil reservoir.

[0010] By adopting the above technical solution, during the sorting of balls, the movable push column will drive the movable parts to move, which in turn will drive the piston rod to move, which in turn will drive the piston plate to move. The piston plate will then squeeze the lubricating oil in the oil storage tank, thereby automatically discharging the lubricating oil into the feed pipe through the oil drain pipe.

[0011] In a preferred embodiment, an oil inlet pipe is connected to one side of the oil storage tank, and a one-way valve is fixedly connected to the outer wall of the oil inlet pipe.

[0012] By adopting the above technical solution, when the piston plate moves towards the piston rod, the oil reservoir will be replenished with new lubricating oil through the oil inlet pipe. When the piston plate moves towards the oil outlet pipe, because the oil inlet pipe is equipped with a one-way valve, the lubricating oil in the oil reservoir will not flow to the oil inlet pipe, and all the lubricating oil in the oil reservoir will be discharged through the oil outlet pipe.

[0013] In a preferred embodiment, a dust collection box is connected to one side of the feeding pipe. A support member is fixedly connected to the inner wall of the dust collection box. A transmission rod is rotatably connected to the inner wall of the support member. A dust collection fan blade is fixedly connected to the outer wall of the transmission rod. A dust collection motor is rotatably connected to one end of the transmission rod. A motor switch is fixedly connected to one side of the dust collection motor.

[0014] By adopting the above technical solution, when sorting the balls, the staff can turn on the dust collection motor, which will drive the transmission rod to rotate the dust collection fan blades. The dust collection fan blades will generate suction to suck the impurities and dust on the balls into the dust collection box, thus preventing the impurities and dust on the balls from affecting the size of the balls for grading.

[0015] In a preferred embodiment, a corresponding extrusion column is provided on one side of the motor switch, a movable push plate is fixedly connected to one side of the corresponding extrusion column, a transmission gear is fixedly connected to the outer wall of the transmission roller, a movable rack is meshed on the outer wall of the transmission gear, and the movable rack is fixedly connected to one side of the movable push plate.

[0016] By adopting the above technical solution, when sorting the balls, the transmission roller will drive the transmission gear to mesh with the movable rack, the movable rack will drive the movable push plate to move the corresponding extrusion column, the corresponding extrusion column will squeeze the motor switch to turn on the dust collection motor, the dust collection motor will make the dust collection fan blades rotate to suck the impurities and dust on the balls into the dust collection box.

[0017] In a preferred embodiment, a filter screen is fixedly connected to the inner wall of the dust collection box, and the filter screen is disposed between the feeding pipe and the dust collection fan blades.

[0018] By adopting the above technical solution, the filter screen can prevent impurities and dust drawn into the dust collection box from directly contacting the dust collection fan blades and affecting the rotation of the dust collection fan blades.

[0019] In a preferred embodiment, a movable slider is fixedly connected to one side of the movable rack, and a limiting groove is formed on the outer wall of the sorting turntable, with the movable slider slidably connected to the inner wall of the limiting groove.

[0020] By adopting the above technical solution, when the movable rack moves, it will drive the movable slider to move. The movable slider will move within the limit groove, and the movable slider will cooperate with the limit groove to limit the movement of the movable rack, so that after the movable rack moves, it can accurately drive the corresponding extrusion column extrusion motor switch.

[0021] In a preferred embodiment, a return spring is fixedly connected to one side of the movable push plate, and the return spring is fixedly connected to the outer wall of the dust collection box.

[0022] By adopting the above technical solution, the reset spring can reset the movable push plate after it has moved, thereby enabling the dust collection motor to automatically open and close.

[0023] A method for sorting balls used in bearing production includes the following steps: S1: When sorting balls, the drive roller will drive the rotating plate to push the balls onto the screening steps. At the same time, the drive roller will drive the movable rotating plate to move the movable push column. The movable push column will drive the push bar to move the movable plate. The movable plate will move obliquely through the movable bar. The movable plate will drive the push plate to move. The push plate will push the balls stuck on the screening steps. S2: When sorting balls, the movable push column will drive the movable part to move, which will drive the piston rod to move, and the piston rod will drive the piston plate to move. When the piston plate moves towards the piston rod, the oil tank will be replenished with new lubricating oil. When the piston plate moves towards the oil drain pipe, the lubricating oil in the oil tank will be discharged into the feed pipe through the oil drain pipe. S3: During the sorting of balls, the transmission roller will drive the transmission gear to rotate, the transmission gear will mesh with the movable rack, the movable rack will drive the movable push plate to move, the movable push plate will drive the corresponding extrusion column to move, and the corresponding extrusion column will extrude the impurities and dust on the balls. The motor switch will turn on the dust collection motor, and the dust collection motor will drive the dust collection fan blades to rotate through the transmission rod, thereby sucking the impurities and dust on the balls into the dust collection box.

[0024] The technical effects and advantages of this invention are as follows: This invention incorporates a movable rotating plate and a pusher plate. During ball sorting, the transmission roller drives the movable rotating plate, which in turn moves the movable pusher column. The movable pusher column then moves the movable bar, which in turn moves the movable plate. The movable plate moves obliquely via the movable bar, which in turn moves the pusher plate obliquely. The pusher plate then pushes the balls on the screening steps, preventing the balls from getting stuck in the screen holes. This solves the problem of balls getting stuck in the screen holes, which prevents subsequent balls from moving and renders the entire sorting device unusable. This invention incorporates a movable component and a piston plate. During ball sorting, the movable push column moves the movable component, which in turn moves the piston rod. The piston rod then moves the piston plate. When the piston plate moves towards the piston rod, the oil reservoir replenishes with new lubricating oil. When the piston plate moves towards the oil drain pipe, the lubricating oil in the reservoir is drained into the feed pipe. This lubricating oil lubricates the balls, preventing damage caused by excessive friction during transport. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Refer to the instruction manual appendix Figure 1-9An embodiment of the present invention provides a ball bearing sorting device for bearing production, comprising a feed pipe 1, a sorting turntable 2, and a feeding pipe 3. The sorting turntable 2 is connected to the bottom of the feed pipe 1, and the feeding pipe 3 is connected to one side of the sorting turntable 2. A screening step 4 for grading the ball bearings by size is fixedly connected to one side of the feeding pipe 3. A transmission roller 5 for driving a rotating plate 6 to rotate is rotatably connected to the inner wall of the sorting turntable 2. A rotating plate 6 for pushing the balls is fixedly connected to the outer wall of the transmission roller 5. A rotary motor 7 for driving the transmission roller 5 to rotate is rotatably connected to one end of the transmission roller 5. The rotary motor 7 is an HG-JR2034 series servo rotary motor. A movable rotating plate 8 for driving a movable push column 9 to rotate is fixedly connected to the end of the transmission roller 5 away from the rotary motor 7. A movable push column 9 for driving a push bar 10 to move is fixedly connected to one side of the movable rotating plate 8. Figure 2 As shown, the outer wall of the movable push column 9 is hinged with a push bar 10 for moving the movable plate 12. One side of the push bar 10 is hinged with a first support shaft 11 for hinged connection between the push bar 10 and the movable plate 12. The outer wall of the first support shaft 11 is hinged with the movable plate 12 for moving the pusher plate 13. The bottom of the movable plate 12 is fixedly connected with the pusher plate 13 for pushing and locking the ball bearings. The top of the movable plate 12 is hinged with a second support shaft 14 for hinged connection between the movable plate and the movable bar 15. The outer wall of the second support shaft 14 is hinged with the movable bar 15 for moving the movable plate 12 obliquely. The outer wall of the movable bar 15 is hinged with a third support shaft 16 for hinged connection between the movable bar 15 and the support frame 17. The outer wall of the third support shaft 16 is hinged with a support frame 17 for supporting the third support shaft 16. The support frame 17 is fixedly connected to the outer wall of the sorting turntable 2.

[0037] It should be noted that during the sorting of balls, the rotary motor 7 drives the rotating plate 6 to rotate via the transmission roller 5. The rotating plate 6 then pushes the balls onto the screening step 4 through the feeding pipe 3. Simultaneously, the transmission roller 5 drives the movable rotating plate 8 to rotate, which in turn drives the movable push column 9 to move. The movable push column 9 then drives the push bar 10 to move, which in turn drives the movable plate 12 to move via the first support shaft 11. Furthermore, the movable bar 15, via the second support shaft 14, ensures that the movable plate 12 can only move obliquely. The movable plate 12 then drives the pusher plate 13 to move obliquely, which in turn pushes the balls on the screening step 4, preventing the balls from getting stuck in the screen holes. This solves the problem of balls getting stuck in the screen holes, which prevents subsequent balls from moving and renders the entire sorting device unusable.

[0038] Furthermore, such as Figure 1As shown, a storage tank 18 for storing lubricating oil is fixedly connected to one side of the sorting turntable 2. A drain pipe 19 for discharging lubricating oil into the feed pipe 1 is connected to one side of the storage tank 18. The drain pipe 19 is connected to the outer wall of the feed pipe 1. A movable part 20 for moving the piston rod 21 is sleeved on the outer wall of the movable push column 9. A piston rod 21 for moving the piston plate 22 is fixedly connected to one side of the movable part 20. A piston plate 22 for squeezing the lubricating oil in the storage tank 18 is fixedly connected to one end of the piston rod 21. The piston plate 22 is slidably connected to the inner wall of the storage tank 18. An oil inlet pipe 23 for connecting to an external lubricating oil supply mechanism is connected to one side of the storage tank 18. A one-way valve 24 for preventing the lubricating oil in the storage tank 18 from flowing to the oil inlet pipe 23 is fixedly connected to the outer wall of the oil inlet pipe 23.

[0039] It should be noted that during the sorting of the balls, the movable pusher 9 will drive the movable part 20 to move, which in turn will drive the piston rod 21 to move. The piston rod 21 will then drive the piston plate 22 to move. When the piston plate 22 moves toward the piston rod 21, the oil reservoir 18 will be replenished with new lubricating oil through the oil inlet pipe 23. When the piston plate 22 moves toward the oil outlet pipe 19, since the oil inlet pipe 23 is equipped with a one-way valve 24, the lubricating oil in the oil reservoir 18 will not flow toward the oil inlet pipe 23. All the lubricating oil in the oil reservoir 18 will be discharged into the feed pipe 1 through the oil outlet pipe 19. The lubricating oil will then lubricate the balls, preventing the balls from being damaged due to excessive friction during transportation.

[0040] Furthermore, such as Figure 9 As shown, a dust collection box 25 for storing impurities and dust is connected to one side of the feeding pipe 3. A support member 26 for supporting the transmission rod 27 is fixedly connected to the inner wall of the dust collection box 25. A transmission rod 27 for driving the dust collection fan blade 28 to rotate is rotatably connected to the inner wall of the support member 26. A dust collection fan blade 28 for generating suction to suck up impurities and dust after rotation is fixedly connected to the outer wall of the transmission rod 27. A dust collection motor 29 for driving the transmission rod 27 to rotate is rotatably connected to one end of the transmission rod 27. The dust collection motor 29 is a QS556 dual-axis rotary stepper motor. A motor switch 30 for controlling the opening and closing of the dust collection motor 29 is fixedly connected to one side of the dust collection motor 29. A corresponding extrusion column 31 for pressing the motor switch 30 after movement is provided on one side of the motor switch 30. A movable push plate 32 for driving the corresponding extrusion column 31 to move is fixedly connected to one side of the corresponding extrusion column 31. Figure 6As shown, a transmission gear 33 for meshing with a movable rack 34 is fixedly connected to the outer wall of the transmission roller 5. The outer wall of the transmission gear 33 meshes with a movable rack 34 for moving the movable push plate 32. The movable rack 34 is fixedly connected to one side of the movable push plate 32. A filter screen 35 for preventing dust and impurities from directly contacting the dust collecting fan blades 28 is fixedly connected to the inner wall of the dust collection box 25. The filter screen 35 is located between the feeding pipe 3 and the dust collecting fan blades 28. A movable slider 36 for limiting the movement of the movable rack 34 in conjunction with a limiting groove 37 is fixedly connected to one side of the movable rack 34. A limiting groove 37 is opened on the outer wall of the sorting turntable 2. The movable slider 36 is slidably connected to the inner wall of the limiting groove 37. A reset spring 38 for resetting the movable push plate 32 after it has moved is fixedly connected to one side of the movable push plate 32. The reset spring 38 is fixedly connected to the outer wall of the dust collection box 25.

[0041] It should be noted that during the sorting of balls, the transmission roller 5 drives the transmission gear 33 to rotate, which in turn meshes with the movable rack 34. The movable rack 34 then drives the movable push plate 32 to move, which in turn drives the corresponding extrusion column 31 to move. The corresponding extrusion column 31 then extrudes the motor switch 30, which turns on the dust collection motor 29. The dust collection motor 29 then drives the transmission rod 27 to rotate, which in turn drives the dust collection fan blade 28 to rotate. The dust collection fan blade 28 then generates suction to draw impurities and dust from the balls into the dust collection box 25, thus preventing impurities and dust from the balls from affecting the size of the balls during sorting.

[0042] A method for sorting balls used in bearing production includes the following steps: S1: When sorting balls, the drive roller 5 will drive the rotating plate 6 to push the balls onto the screening step 4. At the same time, the drive roller 5 will drive the movable rotating plate 8 to move the movable push column 9. The movable push column 9 will drive the push bar 10 to move the movable plate 12. The movable plate 12 will move obliquely through the movable bar 15. The movable plate 12 will drive the pusher plate 13 to move. The pusher plate 13 will push the balls stuck on the screening step 4. S2: When sorting the balls, the movable push column 9 will drive the movable part 20 to move, the movable part 20 will drive the piston rod 21 to move, the piston rod 21 will drive the piston plate 22 to move. When the piston plate 22 moves towards the piston rod 21, the oil tank 18 will be replenished with new lubricating oil. When the piston plate 22 moves towards the oil drain pipe 19, the lubricating oil in the oil tank 18 will be discharged into the feed pipe 1 through the oil drain pipe 19. S3: When sorting the balls, the transmission roller 5 will drive the transmission gear 33 to rotate, the transmission gear 33 will mesh with the movable rack 34, the movable rack 34 will drive the movable push plate 32 to move, the movable push plate 32 will drive the corresponding extrusion column 31 to move, the corresponding extrusion column 31 will extrude the motor switch 30 to turn on the dust collection motor 29, the dust collection motor 29 will drive the dust collection fan blade 28 to rotate through the transmission rod 27, thereby sucking the impurities and dust on the balls into the dust collection box 25.

[0043] Working principle: During ball sorting, the rotary motor 7 drives the rotating plate 6 to rotate via the transmission roller 5. The rotating plate 6 pushes the balls onto the screening step 4 through the feeding pipe 3. Simultaneously, the transmission roller 5 drives the movable rotating plate 8 to rotate, which in turn drives the movable push column 9 to move. The movable push column 9 then drives the push bar 10 to move, which in turn drives the movable plate 12 to move via the first support shaft 11. Furthermore, the movable bar 15, via the second support shaft 14, restricts the movable plate 12 to move only diagonally. The movable plate 12 then drives the pusher plate 13 to move diagonally, which in turn pushes the balls on the screening step 4. During ball sorting, the movable push column 9 drives the movable component 20 to move, which in turn drives the piston rod 21 to move. The piston rod 21 then drives the piston plate 22 to move. When the piston plate 22 moves towards the piston rod 21... The oil storage tank 18 will be replenished with new lubricating oil through the oil inlet pipe 23. When the piston plate 22 moves towards the oil outlet pipe 19, since the oil inlet pipe 23 is equipped with a one-way valve 24, the lubricating oil in the oil storage tank 18 will not flow to the oil inlet pipe 23. All the lubricating oil in the oil storage tank 18 will be discharged into the feed pipe 1 through the oil outlet pipe 19. When sorting the balls, the transmission roller 5 will drive the transmission gear 33 to rotate. The transmission gear 33 will mesh with the movable rack 34. The movable rack 34 will drive the movable push plate 32 to move. The movable push plate 32 will drive the corresponding extrusion column 31 to move. The corresponding extrusion column 31 will extrude the corresponding extrusion column. The motor switch 30 will turn on the dust collection motor 29. The dust collection motor 29 will drive the transmission rod 27 to rotate. The transmission rod 27 will drive the dust collection fan blade 28 to rotate. The dust collection fan blade 28 will generate suction to suck the impurities and dust on the balls into the dust collection box 25.
