[0021] Figures 1-14The best embodiment of the present invention is shown below in conjunction with the attached Figures 1-14 The present invention is further described.

[0022] Refer to the attached Figures 1-14 A high-precision outer diameter sorting device for steel balls includes a frame 1, a feed end at the top of the frame 1 is tilted higher than the discharge end, a discharge mechanism is provided on one side of the frame 1, and multiple screening mechanisms are provided in the frame 1, the screening mechanism includes a first screening rod 16 and a second screening rod 17, both ends of the first screening rod 16 and the second screening rod 17 are provided with an angle adjustment component, the angle adjustment component includes two L-shaped sliders 11, a rectangular cavity 10 is opened in the frame 1, the two L-shaped sliders 11 are movably installed in the rectangular cavity 10, and the two L-shaped sliders 11 are movably connected to the ends of the first screening rod 16 and the second screening rod 17 respectively. The distance monitoring mechanism is connected, and one of the screening mechanisms is provided with a distance monitoring mechanism, which includes a distance meter 31 and a distance measuring plate 32. Specifically, the distance meter 31 is a prior art. For details, reference can be made to the distance meter disclosed in the utility model patent CN218331975U. Its specific working principle is not described here. The distance meter 31 and the distance measuring plate 32 are respectively slidably provided below the first screening rod 16 and the second screening rod 17. Multiple groups of collecting mechanisms are provided below the frame 1. The collecting mechanism includes a collecting box 39. The bottom of the collecting box 39 is provided with a shunt pipe 3. Position adjustment components are provided on both sides of the collecting box 39. In this embodiment, the angle adjustment components at both ends of the first screening rod 16 and the second screening rod 17 act synchronously.

[0023] like Figure 3 、 Figure 4 and Figure 6 As shown, the discharge mechanism includes a placement plate 2, which is fixedly mounted on one side of the feed end of the frame 1. The bottom inner wall of the placement plate 2 is flush with the top of the frame 1. The side of the placement plate 2 is provided with an upper flange, and the side of the placement plate 2 connected to the feed end is not provided with an upper flange. A plurality of diverter plates 6 are fixedly mounted on the top of the placement plate 2, and a plurality of channels are formed on the upper side of the placement plate 2. A guide component is provided in each channel. The guide component includes two guide plates 7. The sides of the placement plate 2 and the diverter plate 6 are provided with rectangular grooves, and the two rectangular grooves are fixed. A fixed shaft is installed, and the two guide plates 7 are rotatably installed on the two fixed shafts respectively. The guide plates 7 are tilted so that the distance between the two guide plates 7 gradually becomes smaller along the direction of material movement. Telescopic plates 8 are slidably installed in the two guide plates 7. An upper sliding hole 15 is opened on the side of the rectangular cavity 10. Two connecting plates 14 are slidably installed in the upper sliding hole 15. The two connecting plates 14 are respectively fixedly connected to the two L-shaped sliders 11. The tops of the two connecting plates 14 are fixedly installed with mounting shafts 9, and the two telescopic plates 8 are rotatably installed on the two mounting shafts 9 respectively.

[0024] In this embodiment, when the two L-shaped sliders 11 move synchronously, they can drive the two connecting plates 14 to move synchronously, and drive the installation shaft 9 to move synchronously horizontally through the connecting plate 14. When the installation shaft 9 moves, it can drive the telescopic plate 8 to slide in the guide plate 7, and then adjust the angles of the guide plate 7 and the telescopic plate 8, so that the distance between the two telescopic plates 8 is adapted to the diameter of the steel ball, so that only one steel ball passes between the two telescopic plates 8 at a time, avoiding accumulation and other phenomena.

[0025] like Figure 5 and Figure 6 As shown, the angle adjustment assembly also includes a bidirectional screw 12, which is rotatably mounted in the rectangular cavity 10. Two L-shaped sliders 11 are both threadedly mounted on the bidirectional screw 12, and the rectangular cavity 10 restricts the L-shaped sliders 11 to prevent them from rotating. A drive motor 13 is fixedly mounted on the side of the frame 1, and the output shaft of the drive motor 13 is connected to one end of the bidirectional screw 12. The threads at both ends of the bidirectional screw 12 rotate in opposite directions, causing the two L-shaped sliders 11 to move synchronously in opposite directions. The bidirectional screws 12 of each group of screening mechanisms are fixedly connected, that is, the ends of each two adjacent bidirectional screws 12 are fixedly connected.

[0026] In this embodiment, the driving motor 13 drives the bidirectional screw 12 to rotate, and then through the threaded action of the bidirectional screw 12 and the L-shaped slider 11 and the limit between the L-shaped slider 11 and the rectangular cavity 10, the two L-shaped sliders 11 are driven to move synchronously toward or away from each other, thereby facilitating the distance adjustment between the first screening rod 16 and the second screening rod 17.

[0027] like Figure 7 and Figure 8 As shown, the angle adjustment assembly also includes two telescopic slides 18, and a transmission cavity is provided in the two L-shaped sliders 11. The two telescopic slides 18 are respectively slidably installed in the two transmission cavities, and the two telescopic slides 18 are limited by the limit unit. One end of the two telescopic slides 18 is movably installed with a connecting ball 19, and the ends of the first screening rod 16 and the second screening rod 17 are fixedly installed with a ball shell 20. The two connecting balls 19 are respectively movably installed in the two ball shells 20, and the connecting balls 19 and the ball shells 20 are combined into a joint bearing. A sliding hole 37 is provided on the side inner wall of the rectangular cavity 10, and the ends of the first screening rod 16 and the second screening rod 17 are both movably set in the sliding hole 37. A limiting hole 36 is provided on the first screening rod 16 and the second screening rod 17, and a limiting shaft 38 is movably installed in the two limiting holes 36. The two ends of the limiting shaft 38 are respectively fixedly installed in the sliding hole 37.

[0028] In this embodiment, when the L-shaped slider 11 moves, it can drive the connecting ball 19 and the first screening rod 16 to move synchronously under the action of the telescopic slide 18. When the first screening rod 16 moves, it can squeeze or stretch the telescopic slide 18 to prevent the first screening rod 16 from getting stuck during the adjustment process. The second screening rod 17 has the same movement as the first screening rod 16, but in the opposite direction.

[0029] like Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the limiting unit includes a spline sleeve 21, which is rotatably installed in the transmission cavity, and a limiting gear 22 is fixedly sleeved on the outside of the spline sleeve 21. A limiting rack 23 meshing with the limiting gear 22 is fixedly installed at the bottom of the telescopic slide 18. A spline shaft 26 is slidably connected in the spline sleeve 21, and an anti-rotation element is provided at the end of the spline shaft 26. The anti-rotation element includes an end spline sleeve 25. A limiting cavity 24 is opened in the frame 1, and one end of the end spline sleeve 25 is rotatably installed in the limiting cavity 24. The other end of the end spline sleeve 25 extends into the transmission cavity and is sleeved on the outside of the spline shaft 26. A threaded hole is opened on the side inner wall of the limiting cavity 24, and a threaded rod 27 is threadedly installed in the threaded hole. An extrusion plate 28 adapted to the limiting cavity 24 is rotatably installed on one end of the threaded rod 27. An anti-slip pad 29 is fixedly installed on the side of the extrusion plate 28, and a knob 30 is fixedly installed on the other end of the threaded rod 27.

[0030] In this embodiment, by turning the knob 30 to drive the threaded rod 27 to rotate, the threaded action between the threaded rod 27 and the threaded hole can drive the extrusion plate 28 and the anti-slip pad 29 to move synchronously, thereby releasing the limit on the end spline sleeve 25, so that when adjusting the first screening rod 16 and the second screening rod 17, the telescopic slide 18 can slide freely, preventing the telescopic slide 18 from getting stuck during the sliding process due to the meshing action between the limit gear 22 and the limit rack 23. After the adjustment of the first screening rod 16 and the second screening rod 17 is completed, the end spline sleeve 25 can be limited by the extrusion plate 28 and the anti-slip pad 29, so that the spline shaft 26, the spline sleeve 21, and the limit gear 22 can be limited, thereby limiting the limit rack 23 and the telescopic slide 18, thereby avoiding the first screening rod 16 and the second screening rod 17 from sliding during the screening process.

[0031] like Figure 11 and Figure 12As shown, the spacing monitoring mechanism includes two moving blocks 35, and the outer walls of the first screening rod 16 and the second screening rod 17 are provided with moving grooves. The two moving blocks 35 are respectively slidably installed in the two moving grooves through moving components. The moving components include a moving screw 33, and the moving screw 33 is rotatably installed in the moving groove. A motor groove is provided on the side of the moving groove, and a moving motor 34 connected to the moving screw 33 is fixedly installed in the motor groove. The two moving blocks 35 are respectively threadedly installed on the two moving screws 33, and the moving blocks 35 are slidably connected to the moving groove. The two moving blocks 35 are both L-shaped. The rangefinder 31 and the distance measuring plate 32 are respectively fixedly installed on the opposite sides of the two moving blocks 35, and the opposite sides of the rangefinder 31 and the distance measuring plate 32 are respectively aligned with the middle of the first screening rod 16 and the second screening rod 17.

[0032] In this embodiment, the two moving motors 34 are started to drive the two moving screws 33 to rotate synchronously, so that the two moving blocks 35 drive the two moving blocks 35 to move synchronously horizontally in the moving groove through the action of the threads. When the two moving blocks 35 are moving, they can drive the rangefinder 31 and the rangefinder plate 32 to move synchronously. Since the opposite sides of the rangefinder 31 and the rangefinder plate 32 are aligned with the middle of the first screening rod 16 and the second screening rod 17 respectively, when the distance measured by the rangefinder 31 and the rangefinder plate 32 is X, assuming that the diameters of the first screening rod 16 and the second screening rod 17 are both Y, then the closest distance between the first screening rod 16 and the second screening rod 17 at this position is XY. When it is necessary to screen steel balls with a diameter of XY, the collecting mechanism only needs to be moved below this position to realize the screening function.

[0033] like Figure 13 and Figure 14 As shown, the position adjustment assembly includes a rotating rod 41, a rectangular long hole 40 is opened on the inner wall of the frame 1, the rotating rod 41 is movably installed in the rectangular long hole 40, one end of the rotating rod 41 is rotatably connected to the side of the collecting box 39, and the other end of the rotating rod 41 is provided with a driving unit, a mounting groove 47 is opened in the rectangular long hole 40, a fixed rack 48 is fixedly installed at the bottom of the mounting groove 47, and a movable gear 46 is fixedly sleeved on the outside of the rotating rod 41 and meshed with the fixed rack 48.

[0034] In this embodiment, when the position of the collection box 39 needs to be adjusted, the two movable gears 46 can be driven to rotate synchronously by synchronously rotating the rotating rods 41 on both sides of the collection box 39, and through the meshing action with the fixed rack 48, the two rotating rods 41 and the collection box 39 are driven to realize the movement function, thereby adjusting the position of the collection box 39.

[0035] like Figure 14As shown, the drive unit includes a mounting plate 42, a T-shaped slot 43 is opened on the side of the frame 1, a T-shaped slider 44 is slidably installed in the T-shaped slot 43, the mounting plate 42 is fixedly connected to the T-shaped slider 44, and an adjusting motor 45 is fixedly installed on the side of the mounting plate 42, and the output shaft of the adjusting motor 45 is connected to the end of the rotating rod 41.

[0036] In this embodiment, by starting the adjustment motor 45, the rotating rod 41 can be driven to realize the rotation function, and the limiting effect between the T-shaped slider 44 and the T-shaped slot 43 can limit the mounting plate 42 to prevent it from rotating.

[0037] like Figure 1 As shown, a waste box 4 is provided below the frame 1 , and a protective pad 5 is fixedly mounted on the inner wall of the waste box 4 . Specifically, the protective pad 5 can be made of sponge material.

[0038] In this embodiment, the waste box 4 is provided to centrally collect the steel balls that do not meet the requirements.

[0039] A steel ball sorting method of a steel ball high-precision outer diameter sorting device comprises the following steps: Step 1: The angle adjustment component synchronously adjusts the distance between the two L-shaped sliders 11, the telescopic slide bar 18, the connecting ball 19, the first screening rod 16, and the second screening rod 17 to adapt to steel balls of different diameters; Step 2: Measure the center distance between the first screening rod 16 and the second screening rod 17 through the spacing monitoring mechanism, and adjust the position of the collection box 39 so that when the steel ball rolls along the first screening rod 16 and the second screening rod 17 to this position, the steel ball falls into the collection box 39.

[0040] The working principle and usage process of the present invention are as follows: when in use, the two knobs 30 are rotated respectively to drive the two threaded rods 27 to rotate synchronously, thereby driving the extrusion plate 28 and the anti-slip pad 29 to move synchronously through the threaded action of the threaded rods 27 and the threaded holes, releasing the limiting effect of the extrusion plate 28 on the end spline sleeve 25, so that the end spline sleeve 25 and the spline shaft 26 are in a rotatable state.

[0041] Two drive motors 13 are started respectively according to the required screening steel ball diameter. When the drive motor 13 is working, it can drive multiple bidirectional screw rods 12 to rotate synchronously. When the bidirectional screw rod 12 rotates, it can drive the two L-shaped sliders 11 to move toward or away from each other synchronously through the action of the thread. When the L-shaped slider 11 moves, it can drive the telescopic slide 18 to move synchronously, and then drive the connecting ball 19, the first screening rod 16, and the second screening rod 17 to move toward or away from each other synchronously through the telescopic slide 18, thereby changing the angle between the first screening rod 16 and the second screening rod 17, and thereby adjusting the distance between the first screening rod 16 and the second screening rod 17.

[0042] When the first screening rod 16 and the second screening rod 17 are in motion, they can drive the telescopic slide 18 to slide, thereby driving the spline sleeve 21 to rotate through the meshing action between the limit rack 23 and the limit gear 22. When the first screening rod 16 and the second screening rod 17 are adjusted to a suitable position, the knob 30 is rotated in the opposite direction to drive the extrusion plate 28 to reset, thereby fixing the spline sleeve 21, the telescopic slide 18, the first screening rod 16, and the second screening rod 17 to improve the stability during the screening process. When the first screening rod 16 and the second screening rod 17 are in horizontal motion, the limiting shaft 38 limits the first screening rod 16 and the second screening rod 17 to prevent them from rotating.

[0043] When the two L-shaped sliders 11 move synchronously toward or away from each other, they can drive the two connecting plates 14 to move synchronously toward or away from each other, and then through the connection of the two mounting shafts 9, drive the two telescopic plates 8 to slide in the two guide plates 7, so that the two guide plates 7 and the two telescopic plates 8 are flipped synchronously to guide the steel balls, and by adjusting the distance between the two telescopic plates 8, only one steel ball can roll to the top of the first screening rod 16 and the second screening rod 17 at a time, realizing the screening function and avoiding blockage and other phenomena.

[0044] Start the two moving motors 34 to drive the two moving screws 33 to rotate synchronously, and then drive the two moving blocks 35 to move synchronously along the two moving grooves through the action of the threads. When the two moving blocks 35 move, they respectively drive the rangefinder 31 and the rangefinder plate 32 to move synchronously. The center distance of the first screening rod 16 and the second screening rod 17 is measured by the rangefinder 31 and the rangefinder plate 32, thereby transmitting electrical signals to two of the adjusting motors 45, so that the two adjusting motors 45 drive the two rotating rods 41 to rotate synchronously. When the two rotating rods 41 rotate synchronously, they drive the two moving gears 46 to rotate synchronously, thereby driving the collecting box 39 to move to an appropriate position through the meshing action between the two moving gears 46 and the two fixed racks 48. When the steel ball rolls to this position along the first screening rod 16 and the second screening rod 17, the steel ball falls into the collecting box 39 to realize the screening function. By adjusting multiple collecting boxes 39 to specified positions, steel balls of different diameters can be screened.
