[0002] Steel balls are widely used in bearings, hardware, electronics, wrought iron, machinery, power, mining, metallurgy, and other fields. The post-production processes for steel balls include cleaning, visual inspection, rust prevention, counting, and packaging; these are all crucial to the quality of the steel balls and require testing during production.

[0003] The diameter and roundness of the steel ball are core indicators for measuring its quality. The testing device uses technologies such as laser measurement and image recognition to capture the dimensional data of the steel ball in real time during the grinding process, ensuring that it meets the preset tolerance range.

[0004] When using existing testing equipment, the appearance of steel balls is inspected through fixed-position testing components, which facilitates the production of steel balls. However, when testing steel balls of different diameters, the position of the testing components needs to be manually adjusted. Errors can easily occur during adjustment due to lack of experience, and the adjustment and calibration are time-consuming. Furthermore, the testing method is singular, which can easily affect the accuracy of steel ball testing and thus affect the production quality and efficiency of steel balls. Utility Model Content

This adjustment is prone to errors due to lack of experience, and calibration is time-consuming. Furthermore, the testing method is limited, which can affect the accuracy of steel ball testing and consequently impact the production quality and efficiency of steel balls. The objective of this utility model can be achieved through the following technical solutions: A testing device for a steel ball grinding machine includes a frame, a conveyor belt fixed on the frame, a testing module mounted on the conveyor belt, and an adjustment mechanism between the testing module and the frame for adjusting the displacement of the testing module. The adjustment mechanism includes a fixed plate fixed to one side of the conveyor belt, a motor fixed on the fixed plate, an adjusting screw fixedly connected to the output end of the motor through the fixed plate, a moving plate fixedly connected to the adjusting screw by ball nuts, a limiting plate fixed on the moving plate, a limiting plate fixedly connected to the detection module, a displacement sensor fixed on the moving plate, a controller fixed on one side of the frame, the controller electrically connected to the displacement sensor, and the controller electrically connected to the motor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 3 As shown, this utility model is a testing device for a steel ball grinding machine, including a frame 1, a conveyor belt 3 fixed on the frame 1, a testing module 2 on the conveyor belt 3, and an adjustment mechanism between the testing module 2 and the frame 1 for adjusting the displacement of the testing module 2. The reciprocating assembly includes a fixed plate 4 fixed to one side of the conveyor belt 3. A motor 5 is fixed on the fixed plate 4. An adjusting screw 6 is fixedly connected to the output end of the motor 5 through the fixed plate 4. A moving plate 7 is fixedly connected to the adjusting screw 6 via a ball nut. A limiting plate 8 is fixed on the moving plate 7. The limiting plate 8 is fixedly connected to the detection module 2. A displacement sensor 14 is fixed on the moving plate 7. A controller 15 is fixed to one side of the frame 1. The controller 15 is electrically connected to the displacement sensor 14 and the motor 5. The reciprocating assembly also includes a testing assembly, which includes a hydraulic telescopic rod 11 fixed to the limiting plate 8. A pressure sensor 12 is fixedly connected to the telescopic end of the hydraulic telescopic rod 11 through the limiting plate 8. A detection plate is fixed to the lower end of the pressure sensor 12. A limiting rod 9 is fixed to the side of the conveyor belt 3 away from the adjusting screw 6. A connecting plate 10 is fixed to the side of the limiting plate 8 away from the moving plate 7. The limiting rod 9 slides through the connecting plate 10.

[0020] Specifically, steel balls are transported via conveyor belt 3. During transport, the outer diameter of the steel balls is detected by detection module 2 to reduce appearance defects. The position of detection module 2 can be easily adjusted by the adjustment mechanism to adapt to the detection of steel balls of different diameters, reducing manual adjustment, reducing adjustment errors, reducing the impact on detection accuracy, improving the production quality and efficiency of steel balls, and facilitating detection. Specifically, the motor 5 rotates the adjusting screw 6, causing the ball nut to drive the moving plate 7, which in turn moves the limiting plate 8. This causes the connecting plate 10 to slide on the limiting rod 9, restricting the limiting plate 8 and moving the detection module 2 to the appropriate position. As the moving block moves, the displacement sensor 14 detects the position of the detection module 2 and feeds the monitoring data back to the controller 15. The controller 15 controls the motor 5 to improve the adjustment accuracy of the detection module 2. The detection data of the detection module 2 is fed back to the grinding machine in real time, facilitating the grinding of the steel balls. The limiting plate 8 drives the hydraulic telescopic rod 11 to rise and fall. During strength testing, the conveyor belt 3 is stopped, and the hydraulic telescopic rod 11 is operated, causing the pressure sensor (YZC-328) 12 to move, driving the detection plate to squeeze the steel ball. During squeezing, the pressure sensor (YZC-328) 12 feeds the data back to the controller 15 for recording. Through a preset program, the strength of the steel ball is detected, facilitating the testing of the steel ball and improving the production quality of the steel ball.

[0021] In this embodiment, refer to Figure 3 - Figure 4 As shown, a horn tube is fixed on the frame 1, and a right-angle tube 17 is fixed at the lower end of the horn tube. An electric telescopic rod 19 is fixed inside the frame 1. The electric telescopic rod 19 extends into the right-angle tube 17 and is rotatably connected to a rotating column. A support plate 18 is fixed inside the frame 1. The support plate 18 is fixedly connected to the right-angle tube 17. An inclined plate 16 is fixed at one end of the support plate 18 and corresponds to the right-angle tube 17. The lower end of the inclined plate 16 corresponds to the conveyor belt 3. Fixed rings 13 are fixed on the conveyor belt 3 and are distributed in an array.

[0022] Specifically, the staff installs the horn tube at the discharge port of the grinder, so that the ground steel balls enter the right-angle tube 17 through the horn tube. At the same time, the electric telescopic rod 19 is operated, so that the rotating column pushes the steel ball to move, causing the steel ball to move and rotate, move out of the right-angle tube 17 and roll onto the conveyor belt 3 through the inclined plate 16. The steel ball is restricted by the fixing ring 13 to facilitate the detection of the steel ball.

[0023] In this embodiment, refer to Figure 2 - Figure 4As shown, a second motor 21 is fixed to the lower end of the frame 1. A bidirectional screw 22 is fixed to the output end of the second motor 21. Two symmetrical adjusting plates 24 are threaded onto the bidirectional screw 22. The bidirectional screw 22 is rotatably connected to the support plate 18. Two symmetrical adjusting rods 25 are fixed on the adjusting plates 24. The adjusting rods 25 extend into the right-angle tube 17 and are fixedly connected to two arc-shaped plates 26. Brushes 27 are fixed on the arc-shaped plates 26 and arranged in an array. The arc-shaped plates 26 are semi-circular arcs and are staggered. A limiting post 23 is fixed inside the frame 1. The limiting post 23 is located on one side of the bidirectional screw 22 and slides through the support plate 18 and the adjusting plate 24. A sponge block 28 is fixed on the arc-shaped plate 26 and is located on one side of the brush 27. Flexible rubber pads are fixed inside the right-angle tube 17 and on the rotating post.

[0024] Specifically, the second motor 21 rotates the bidirectional screw 22, causing the two adjusting plates 24 to move relative to each other, which in turn causes the adjusting rod 25 to move. The adjusting plates 24 slide on the limiting post 23, which restricts the adjusting plates 24 and drives the arc plate 26 to move relative to each other. This allows the brush 27 to clean steel balls of different diameters, reducing metal, oil, and other debris on the surface of the steel balls, facilitating steel ball detection, reducing the impact of debris on the detection accuracy of the steel balls, and improving the detection accuracy of the steel balls. The rolling steel balls pass through the sponge block 28, reducing the amount of coolant and other liquids on the surface of the steel balls, which facilitates subsequent steel ball detection. The flexible rubber pad restricts and protects the steel balls, reducing surface damage to the steel balls and facilitating steel ball detection.

[0025] The working principle of this utility model is as follows: The operator installs the horn tube into the discharge port of the grinder, so that the ground steel ball enters the right-angle tube 17 through the horn tube. At the same time, the electric telescopic rod 19 is operated, so that the rotating column pushes the steel ball to move, so that the steel ball moves and rotates, moves out of the right-angle tube 17 and rolls onto the conveyor belt 3 through the inclined plate 16. The steel ball is restricted by the fixing ring 13. Then, the motor 5 is operated, causing the adjusting screw 6 to rotate, which in turn causes the ball nut to drive the moving plate 7, which in turn causes the limiting plate 8 to move. This causes the connecting plate 10 to slide on the limiting rod 9, thus restricting the limiting plate 8 and moving the detection module 2 to the appropriate position. When the moving block moves, the displacement sensor detects the position of the detection module 2 and feeds the detection data back to the controller 15. The controller 15 controls the motor 5 to improve the adjustment accuracy of the detection module 2 and feeds the detection data of the detection module 2 back to the grinding machine in real time, which facilitates the grinding of the steel ball. The limiting plate 8 drives the hydraulic telescopic rod 11 to rise and fall. During strength testing, the conveyor belt 3 is stopped, and the hydraulic telescopic rod 11 is operated, causing the pressure sensor (YZC-328) 12 to move and drive the detection plate to squeeze the steel ball. During squeezing, the pressure sensor (YZC-328) 12 feeds the data back to the controller 15 for recording. The strength of the steel ball is detected through a preset program. Then, the second motor 21 is operated, causing the bidirectional screw 22 to rotate, which in turn causes the two adjusting plates 24 to move relative to each other, and the adjusting rod 25 to move relative to each other, which in turn causes the arc plate 26 to move relative to each other, so that the brush 27 cleans the steel balls of different diameters, reducing metal, oil and other debris on the surface of the steel balls, which facilitates the detection of the steel balls, reduces the impact of debris on the detection accuracy of the steel balls, and improves the detection accuracy of the steel balls. The rolling steel balls pass through the sponge block 28, which reduces the amount of coolant and other liquids on the surface of the steel balls, which facilitates the subsequent detection of the steel balls. The flexible rubber pad restricts and protects the steel balls.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
