Description

Technical Field

[0001] The invention relates to the technical field of experimental ball size detection, in particular to an experimental ball size detection device for a visualized probability directional motion test. Background Art

[0002] In the visualized probability directional motion test, the experimental ball is a tool used to intuitively display and simulate probability distribution and object motion characteristics. As a visualization carrier, the experimental ball can transform abstract probability distribution or motion characteristics into specific physical phenomena. By observing and recording the motion trajectory and distribution state of the ball, the relevant probability and physical concepts can be intuitively understood. For the accuracy and repeatability of the experiment, the size consistency of the experimental ball is one of the key factors to ensure the reliability of the experimental results. Therefore, size detection of the experimental ball is very important.

[0003] The existing size detection methods for experimental balls are mostly to clamp and measure the experimental balls through conventional general measuring tools such as vernier calipers. However, in order to pursue measurement accuracy, the experimental balls often need to be tightly clamped, which greatly increases the risk of damage to the surface of the balls. The tight clamping operation may not only scratch or wear the surface of the balls, but also cause tiny deformations due to stress concentration, which will have an adverse effect on the surface accuracy of the experimental balls. The surface accuracy of the experimental balls is an important part of their physical properties, which is directly related to the performance of the balls in motion tests, such as rolling stability, consistency of bounce height, and rebound angle after collision. Once the surface accuracy of the balls is damaged, these motion characteristics will be affected, thereby affecting the accuracy and reliability of the experimental data, and the practicality is poor. Summary of the invention

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention can not only perform preliminary screening and secondary screening on the experimental balls before size detection through the mutual cooperation of the air-blowing suspension mechanism, the detection mechanism and the soft fixing mechanism, so as to quickly identify and exclude the experimental balls that do not meet the size requirements, but also complete the cleaning of the experimental balls without any contact, thereby effectively ensuring the efficiency and quality of subsequent size detection of the experimental balls. After the screening and cleaning work is completed, the soft fixing mechanism can realize soft fixation and multiple fixation of the experimental balls, which not only ensures that the experimental balls will not move or shake during the detection process, but also avoids the physical damage that may be caused by the traditional fixing method, thereby effectively ensuring the accuracy and reliability of the size detection of the experimental balls.

[0020] 2. The present invention, through the setting of the air-blowing suspension mechanism, utilizes the stable suspension state of the experimental ball (the compressed gas overflowing from the graphite block enables the experimental ball to be suspended) and the matching relationship between the grooves on the graphite block and the experimental ball, so as to effectively perform preliminary screening of the experimental balls for size detection, and can quickly identify and exclude those experimental balls that obviously do not meet the size requirements, thereby reducing the workload of subsequent size detection work, and effectively ensuring the efficiency of subsequent size detection of the experimental balls.

[0021] 3. The present invention cooperates with the air-blowing suspension mechanism and the detection mechanism to slightly move the experimental ball in a stable suspension state and rotate it, so that the compressed gas overflowing from the graphite block can remove dust and impurities on the surface of the experimental ball, thereby avoiding scratches or damage to the surface of the experimental ball due to physical contact in traditional cleaning methods, and at the same time avoiding the dust and impurities on the surface of the experimental ball from affecting subsequent size detection, thereby effectively ensuring the quality of the size detection of the experimental ball, and through the visual rangefinder in the detection mechanism, the rotating experimental ball can be roughly measured in all directions and at multiple angles, so that the experimental balls with uniform shapes can be quickly screened out, that is, the secondary screening of the experimental balls is completed, thereby further ensuring the efficiency of subsequent size detection of the experimental balls.

[0022] 4. The present invention, through the arrangement of the induction coil and the ultrasonic component in the air-blowing suspension mechanism, utilizes the electromagnetic induction of the induction coil after power-on and the auxiliary effect of the ultrasonic wave emitted by the ultrasonic component, which can promote the flow of compressed gas in the inflation chamber and provide more escape channels for the compressed gas, while also reducing the gas flow resistance around the pores of the graphite block, thereby optimizing the escape process of the compressed gas through the porous structure of the graphite block and effectively improving the escape efficiency of the compressed gas, thereby enabling the experimental ball to be more stably suspended.

[0023] 5.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] Reference Figures 1 to 5A device for detecting the size of an experimental ball for a visual probability direction motion test comprises a base 1, two sets of sliding rods 2 are fixedly installed at the top of the base 1 near the edge, a mounting plate 3 is slidably connected to the two sets of sliding rods 2, a driving part 6 for driving the sliding rod 2 on the mounting plate 3 is provided, the driving part 6 is a prior art, and its specific structural design is not repeated here, an air blowing suspension mechanism is provided at the top of the base 1, an experimental ball 15 is placed on the air blowing suspension mechanism, and the air blowing suspension mechanism is used to suspend the experimental ball 15 and remove dust and impurities on the surface of the experimental ball 15, the air blowing suspension mechanism comprises a fixing frame 19, a mounting groove is opened at the top of the fixing frame 19, a graphite block 16 is fixedly installed at the opening of the mounting groove, an induction coil 17 is installed inside the graphite block 16, and the graphite block 16 and the mounting groove are connected. The gap between the bottom walls is an air-filled cavity 21, and a groove is provided at the top of the graphite block 16. The experimental ball 15 is placed in the groove. The shape of the groove matches the shape of the experimental ball 15, and the size of the groove is adapted to the size of the experimental ball 15. The shape of the groove matches the shape of the experimental ball 15 to ensure that the experimental ball 15 is smoothly placed in the groove, thereby meeting the needs of size detection, and the size of the groove is adapted to the size of the experimental ball 15 to also meet the needs of size detection. If the groove is too small, the experimental ball 15 may not be able to be placed in. If the groove is too large, the experimental ball 15 may shake or be unstable in the groove. A fixing ring 24 is installed on the inner wall of the air-filled cavity 21. The top of the fixing ring 24 is fixedly connected to the bottom end of the graphite block 16. The fixing ring 24 is used to additionally fix the graphite block 16, thereby improving the installation stability of the graphite block 16.

[0034] Reference Figure 1 , Figure 4 and Figure 5 The graphite block 16 is provided with a gas injection component and an ultrasonic component, which are respectively used to fill the compressed gas into the inflation cavity 21 and to emit ultrasonic waves into the inflation cavity 21. The gas injection component includes an air inlet pipe 22, which passes through and is fixedly installed on the graphite block 16, and the inward end of the air inlet pipe 22 is located in the inflation cavity 21, and the outward end of the air inlet pipe 22 is connected to an external air supply device. The ultrasonic component includes an ultrasonic vibrator 20, which is fixedly installed on the inner wall of the inflation cavity 21, and a connecting wire is installed at the terminal of the ultrasonic vibrator 20, and the end of the connecting wire away from the ultrasonic vibrator 20 passes through the inner wall of the inflation cavity 21 and is connected to an external ultrasonic generator. The air supply device and the ultrasonic generator are both existing technologies, which are not drawn in the figure, and their specific structural design will not be repeated here.

[0035] By turning on the external air supply equipment and cooperating with the air inlet pipe 22 to continuously fill the air filling cavity 21 in the graphite block 16 with compressed gas, since the graphite block 16 is porous, the compressed gas in the air filling cavity 21 will escape through the uniform pores in the graphite block 16. At this time, the external ultrasonic generator is started, and the ultrasonic vibrator 20 connected to it is driven by the connecting line to emit ultrasonic waves in the air filling cavity 21. These ultrasonic waves will generate high-frequency, alternating density pressure waves in the compressed gas. This pressure wave gives the gas molecules additional kinetic energy, causing the vibration of the gas molecules to become more violent, thereby promoting the flow of compressed gas in the air filling cavity 21.

[0036] At the same time, the induction coil 17 in the graphite block 16 is energized. At this time, according to the principle of electromagnetic induction, the induction coil 17 will generate a magnetic field. This magnetic field will induce an electric current in the graphite block 16, thereby generating heat to properly heat the graphite block 16 (the graphite block 16 is composed of carbon atoms arranged in a specific manner to form a plurality of parallel molecular layers, and these molecular layers are interconnected by weak van der Waals forces). When the graphite block 16 is heated, the carbon atoms inside it will begin to vibrate more violently, that is, the thermal motion intensifies. Since the van der Waals force is relatively weak, as the thermal motion of carbon atoms intensifies (that is, as the temperature rises), the interaction between carbon atoms in multiple molecular layers will weaken, and this weakening will lead to a more obvious increase in the distance between layers, thereby providing more escape channels for the compressed gas. In addition, the magnetic field generated after the induction coil 17 is energized can provide additional energy for the gas molecules in the compressed gas, prompting the gas molecules adsorbed on the surface of the graphite block 16 to desorb, thereby reducing the gas flow resistance around the pores of the graphite block 16.

[0037] At this time, the experimental ball 15 is placed in the groove at the top of the graphite block 16. Due to the compressed gas overflowing from the graphite block 16, the experimental ball 15 will reach a stable suspended state in the groove, and because the shape of the groove matches the shape of the experimental ball 15, and the size of the groove is adapted to the size of the experimental ball 15, this ensures that only the experimental ball 15 of the right size can be placed in the groove, and the experimental ball 15 of a larger size will not be able to be placed in the groove, thereby directly excluding and scrapping this part of the experimental balls 15 of a larger size. Secondly, for the experimental ball 15 that can be placed in the groove, if it cannot reach a stable suspended state under the action of compressed gas, this usually means that the size of the experimental ball 15 has a large deviation, that is, the experimental ball 15 is smaller in size, thereby directly excluding and scrapping this part of the experimental balls 15 of a smaller size, because the mass of the experimental ball 15 of a smaller size is not enough to resist the thrust of the compressed gas, and thus cannot maintain a stable suspended state, thereby being able to quickly identify and exclude those experimental balls 15 that obviously do not meet the size requirements.

[0038] Reference Figures 1 to 7A detection mechanism and a soft fixing mechanism are respectively provided on one side of the mounting plate 3 facing the air blowing suspension mechanism, which are respectively used to detect the size of the experimental ball 15 and to softly fix the experimental ball 15. The detection mechanism includes a sliding groove 4, which is opened on the side of the mounting plate 3 facing the air blowing suspension mechanism, and an electric slider 5 is slidably connected in the sliding groove 4. A visual rangefinder 23 is installed on one end of the electric slider 5 facing the air blowing suspension mechanism. The soft fixing mechanism includes a fixing plate 9, which is fixedly mounted on the side of the mounting plate 3 facing the air blowing suspension mechanism, and the fixing plate 9 is located above the detection mechanism. A rubber body 10 is fixedly connected to the bottom end of the fixing plate 9. The inside of the rubber body 10 is hollow, and the rubber body 10 and the fixing plate 9 is a through-connection, and a vacuum assembly is arranged on the fixed plate 9 for extracting the gas in the rubber body 10. The vacuum assembly includes a vacuum section 7, which is fixedly mounted on the top of the fixed plate 9, and a vacuum pipe is installed at the input end of the vacuum section 7. The vacuum section 7 is a prior art, and its specific structural design is not repeated here. One end of the vacuum pipe away from the vacuum section 7 passes through the top wall of the fixed plate 9 and is connected to the inside of the rubber body 10. A one-way valve 8 is installed on the vacuum pipe. The bottom end of the rubber body 10 is in an arc shape, and a magnetic fluid 14 is arranged in the rubber body 10. An arc-shaped electromagnetic plate 18 is arranged on the fixed frame 19, and the bottom end of the arc-shaped electromagnetic plate 18 is fixedly connected to the outer wall of the fixed frame 19, and the top end of the arc-shaped electromagnetic plate 18 is in an unfolded state.

[0039] After the experimental ball 15 is suspended, the experimental ball 15 is slightly moved to rotate in the groove, and the compressed gas overflowing from the graphite block 16 is used to remove dust and impurities on the surface of the experimental ball 15, so that the cleaning work of the experimental ball 15 can be completed without any contact, avoiding scratches or damage to the surface of the experimental ball 15 due to physical contact in traditional cleaning methods, and avoiding the dust and impurities on the surface of the experimental ball 15 from affecting subsequent size detection. When the experimental ball 15 rotates in the groove, the electric slider 5 is started to move it downward in the sliding groove 4, thereby driving the visual rangefinder 23 thereon to move downward and move to a height corresponding to the position of the experimental ball 15. This operation enables the visual rangefinder 23 to perform a comprehensive and multi-angle rough measurement of the rotating experimental ball 15, so that the experimental balls 15 with uniform shapes can be quickly screened out, that is, further screening of the experimental balls 15 is completed.

[0040] Reference Figures 1 to 3 as well as Figure 6 and Figure 7, an adsorption assembly is installed near the bottom of the side wall of the rubber body 10 for adsorbing and fixing the experimental ball 15, the adsorption assembly includes four groups of movable connecting parts, the four groups of movable connecting parts are evenly arranged near the bottom of the outer side wall of the rubber body 10, and two groups of suction cups 13 are installed on the four groups of movable connecting parts, the movable connecting parts are used to make the suction cups 13 fit and firmly adsorb on the surface of the experimental ball 15, the suction cups 13 are mainly composed of a suction cup soft shell and a suction cup mouth, the suction cup soft shell is an extrusion cavity 131, the extrusion cavity 131 is connected to the suction cup mouth, the suction cup 13 is a prior art The specific structural design is not described here. The movable connecting component includes a curved recessed block 11, which is fixedly mounted on the outer wall of the rubber body 10, and the interior of the curved recessed block 11 is connected to the interior of the rubber body 10. The recesses on the curved recessed block 11 are fixedly connected with protruding columns 12, the protruding columns 12 are hollow, and the connection between the protruding columns 12 and the curved recessed block 11 is through-set. The suction cup 13 is fixedly mounted on the outer wall of the protruding column 12 toward the bottom end of the rubber body 10, and the extrusion cavity 131 in the suction cup 13 is located in the protruding column 12.

[0041] After the rough measurement is completed, the driving unit 6 is started to make the mounting plate 3 descend along the sliding rod 2 until the rubber body 10 at the bottom end of the fixing plate 9 is in close contact with the upper surface of the test ball 15. This close contact will cause the rubber body 10 to be concave under the pressure of the test ball 15. Since the rubber body 10 is connected to the curved concave block 11, and the concave part of the curved concave block 11 is fixedly connected to the protruding column 12, when the rubber body 10 is concave, the protruding column 12 will be squeezed out from the concave part of the curved concave block 11, and the rubber body 10 is pressed. 0 will cause the bottom area of ​​the rubber body 10 to deform, and this deformation will cause the bent recessed block 11 and the protruding column 12 on the bent recessed block 11 to deviate toward the recessed portion at the bottom end of the rubber body 10. Since the outer wall of the protruding column 12 passes through the recessed portion at the bottom end of the rubber body 10 and is fixedly installed by the suction cup 13, when the protruding column 12 deviates inwardly, the suction cup 13 will contact the surface of the experimental ball 15. At this time, the magnetic fluid 14 in the rubber body 10 also evenly covers the experimental ball 15 through the rubber body 10.

[0042] Then, the air extraction unit 7 is started to slowly and slightly extract air from the rubber body 10 through the air extraction pipe. This step causes the air pressure inside the rubber body 10 to gradually decrease, forming a pressure difference with the external environment. Due to the existence of this internal and external pressure difference, the rubber body 10 will be squeezed, so that it fits more closely on the surface of the test ball 15. At the same time, since the extrusion cavity 131 inside the suction cup 13 is inside the protruding column 12, and the protruding column 12 is connected to the inside of the rubber body 10 through the bent recessed block 11, during the process of the rubber body 10 being squeezed, the extrusion cavity 131 will also be squeezed accordingly, and this squeezing causes the air inside the extrusion cavity 131 to be discharged through the suction cup opening on the suction cup 13, thereby forming a negative pressure inside the suction cup 13. This negative pressure enables the suction cup 13 to be firmly adsorbed on the surface of the experimental ball 15 like an octopus tentacle, thereby being able to achieve soft fixation of the experimental ball 15 (i.e., fixation through the elasticity of the rubber body 10 and the adsorption force of the suction cup 13) while also providing a stable fixing effect for the experimental ball 15, ensuring that the experimental ball 15 will not move or shake during the size detection process.

[0043] After the fixation is completed, the air extraction part 7 is closed. Due to the presence of the one-way valve 8, the rubber body 10 will maintain a low pressure state, ensuring the close fit between the rubber body 10 and the experimental ball 15 and the firm adsorption of the suction cup 13 on the experimental ball 15. Then, the arc-shaped electromagnetic plate 18 is energized to generate a strong magnetic field. The unfolded setting of the arc-shaped electromagnetic plate 18 can make the magnetic fluid 14 in the rubber body 10 uniformly affected by the magnetic field. Under the action of the magnetic field, the magnetic fluid 14 is transformed from a fluid state to a solid state, that is, the magnetic curing of the magnetic fluid 14 is completed. The magnetically cured magnetic fluid 14 has higher strength and stability, thereby enhancing the fixing effect of the rubber body 10 on the experimental ball 15. At this time, the experimental ball 15 is firmly fixed by the fitting force of the rubber body 10, the adsorption force of the suction cup 13 and the curing force of the magnetic fluid 14. At this time, the electric slider 5 is moved again, and the visual rangefinder 23 is moved to a suitable place to accurately measure the experimental ball 15, and finally the size detection of the experimental ball 15 is completed.

[0044] In the present invention, firstly, the external air supply equipment is turned on, and compressed gas is continuously filled into the air filling cavity 21 in the graphite block 16 through the air inlet pipe 22. Since the graphite block 16 is porous, the compressed gas in the air filling cavity 21 will escape through the uniform pores in the graphite block 16. At this time, the external ultrasonic generator is started, and the ultrasonic vibrator 20 connected to it is driven by the connecting line to emit ultrasonic waves in the air filling cavity 21. These ultrasonic waves will generate high-frequency, alternating density pressure waves in the compressed gas. This pressure wave gives the gas molecules additional kinetic energy, causing the vibration of the gas molecules to become more violent, thereby promoting the flow of the compressed gas in the air filling cavity 21. Therefore, through the auxiliary effect of ultrasonic waves, the compressed gas can more easily escape through the uniform pores in the graphite block 16, thereby optimizing the gas escape process through the porous structure of the graphite block 16, and achieving more efficient gas flow.

[0045] At the same time, the induction coil 17 in the graphite block 16 is energized. At this time, according to the principle of electromagnetic induction, the induction coil 17 will generate a magnetic field, and this magnetic field will induce an electric current in the graphite block 16, thereby generating heat, and appropriately heating the graphite block 16 (the graphite block 16 is composed of carbon atoms arranged in a specific way to form a plurality of parallel molecular layers, and these molecular layers are interconnected by weak van der Waals forces). When the graphite block 16 is heated, the carbon atoms inside it will begin to vibrate more violently, that is, the thermal motion will intensify. Since the van der Waals force is relatively weak, as the carbon atoms heat up, the heat will be generated. As the movement intensifies (i.e., as the temperature rises), the interaction between the carbon atoms in multiple molecular layers will weaken, and this weakening will lead to a more obvious increase in the distance between the layers, thereby providing more escape channels for the compressed gas, thereby effectively improving the efficiency of the compressed gas escape. In addition, the magnetic field generated after the induction coil 17 is energized can provide additional energy for the gas molecules in the compressed gas, prompting the gas molecules adsorbed on the surface of the graphite block 16 to desorb, thereby reducing the gas flow resistance around the pores of the graphite block 16, thereby further improving the efficiency of the compressed gas escape.

[0046] At this time, the experimental ball 15 is placed in the groove at the top of the graphite block 16. Due to the compressed gas overflowing from the graphite block 16, the experimental ball 15 will reach a stable suspension state in the groove. Since the shape of the groove matches the shape of the experimental ball 15, and the size of the groove is adapted to the size of the experimental ball 15, this ensures that only the experimental ball 15 of the right size can be placed in the groove, and the experimental ball 15 of a larger size cannot be placed in the groove, so that the experimental balls 15 of a larger size can be directly excluded and scrapped. Secondly, for the experimental ball 15 that can be placed in the groove, if it cannot reach a stable suspension state under the action of the compressed gas, this usually means that the size of the experimental ball 15 is too large. There is a large deviation, that is, the experimental ball 15 is small in size, so this part of the experimental balls 15 with smaller sizes can be directly excluded and scrapped, because the mass of the experimental balls 15 with smaller sizes is not enough to resist the thrust of the compressed gas, and thus cannot maintain a stable suspension state. Therefore, by utilizing the compressed gas overflowing from the graphite block 16 and the matching relationship between the grooves on the graphite block 16 and the experimental balls 15, the experimental balls 15 for size detection can be effectively screened preliminarily, and those experimental balls 15 that obviously do not meet the size requirements can be quickly identified and excluded, thereby reducing the workload of subsequent size detection work, and then effectively ensuring the efficiency of subsequent size detection of the experimental balls 15.

[0047] After the test ball 15 is suspended, the test ball 15 is lightly moved to rotate in the groove, and the compressed gas overflowing from the graphite block 16 is used to remove dust and impurities on the surface of the test ball 15, so that the cleaning work of the test ball 15 can be completed without any contact, avoiding scratches or damage to the surface of the test ball 15 due to physical contact in the traditional cleaning method, and avoiding the dust and impurities on the surface of the test ball 15 from affecting the subsequent size detection, thereby effectively ensuring the quality of the size detection of the test ball 15. When the test ball 15 rotates in the groove, the electric slider 5 is started to slide in the sliding groove 4. The visual rangefinder 23 moves downward inward, thereby driving the visual rangefinder 23 thereon to move downward and to a height corresponding to the position of the experimental ball 15. This operation enables the visual rangefinder 23 to perform a rough measurement of the rotating experimental ball 15 in all directions and at multiple angles. Specifically, the visual rangefinder 23 can continuously capture the diameter data of the experimental ball 15 in different directions during its rotation. The comparison and analysis of these data can intuitively reflect the uniformity of the experimental ball 15, thereby being able to quickly screen out the experimental balls 15 with uniform shapes, that is, completing further screening of the experimental balls 15, thereby further ensuring the efficiency of subsequent size detection of the experimental balls 15.

[0048] After the rough measurement is completed, the driving unit 6 is started to make the mounting plate 3 descend along the sliding rod 2 until the rubber body 10 at the bottom end of the fixing plate 9 is in close contact with the upper surface of the test ball 15. This close contact will cause the rubber body 10 to be concave under the pressure of the test ball 15. Since the rubber body 10 is connected to the curved concave block 11, and the concave part of the curved concave block 11 is fixedly connected to the protruding column 12, when the rubber body 10 is concave, the protruding column 12 will be squeezed out from the concave part of the curved concave block 11, and the rubber body 10 is pressed. 0 will cause the bottom area of ​​the rubber body 10 to deform, and this deformation will cause the bent recessed block 11 and the protruding column 12 on the bent recessed block 11 to deviate toward the recessed portion at the bottom end of the rubber body 10. Since the outer wall of the protruding column 12 passes through the recessed portion at the bottom end of the rubber body 10 and is fixedly installed by the suction cup 13, when the protruding column 12 deviates inwardly, the suction cup 13 will contact the surface of the experimental ball 15. At this time, the magnetic fluid 14 in the rubber body 10 also evenly covers the experimental ball 15 through the rubber body 10.

[0049] Then, the air extraction unit 7 is started to slowly and slightly extract air from the rubber body 10 through the air extraction pipe. This step causes the air pressure inside the rubber body 10 to gradually decrease, forming a pressure difference with the external environment. Due to the existence of this internal and external pressure difference, the rubber body 10 will be squeezed, so that it fits more closely on the surface of the test ball 15. At the same time, since the squeezing cavity 131 inside the suction cup 13 is inside the protruding column 12, and the protruding column 12 is connected to the inside of the rubber body 10 through the bent recessed block 11, the squeezing cavity 131 will also be squeezed accordingly during the squeezing of the rubber body 10. This extrusion causes the air inside the extrusion cavity 131 to be discharged through the suction cup opening on the suction cup 13, thereby forming a negative pressure inside the suction cup 13. This negative pressure allows the suction cup 13 to be firmly adsorbed on the surface of the experimental ball 15 like an octopus tentacle, thereby achieving soft fixation of the experimental ball 15 (i.e., fixation through the elasticity of the rubber body 10 and the adsorption force of the suction cup 13) while providing a stable fixing effect for the experimental ball 15, ensuring that the experimental ball 15 will not move or shake during the size detection process, thereby effectively ensuring the accuracy and reliability of the size detection of the experimental ball 15.

[0050] After the fixation is completed, the exhaust part 7 is closed. Due to the presence of the one-way valve 8, the rubber body 10 will maintain a low pressure state, ensuring the close fit between the rubber body 10 and the experimental ball 15 and the firm adsorption of the experimental ball 15 by the suction cup 13. Then, the arc-shaped electromagnetic plate 18 is energized to generate a strong magnetic field. The expanded setting of the arc-shaped electromagnetic plate 18 can make the magnetic fluid 14 in the rubber body 10 uniformly affected by the magnetic field. Under the action of the magnetic field, the magnetic fluid 14 changes from a fluid state to a solid state, that is, the magnetic curing of the magnetic fluid 14 is completed. The magnetically solidified magnetic fluid 14 has higher strength and stability, thereby being able to enhance the fixing effect of the rubber body 10 on the experimental ball 15. At this time, the experimental ball 15 is firmly fixed by the fitting force of the rubber body 10, the adsorption force of the suction cup 13 and the curing force of the magnetic fluid 14. This multiple fixing method further ensures the accuracy and reliability of the size detection of the experimental ball 15. At this time, the electric slider 5 is moved again, and the visual rangefinder 23 is moved to a suitable place to accurately measure the experimental ball 15, thereby finally completing the size detection of the experimental ball 15.

[0051] After the size detection is completed, turn off the relevant power supply, and use the driving unit 6 to make the rubber body 10 leave the surface of the test ball 15, and close the one-way valve 8 at the same time. At this time, the magnetic fluid 14 will restore the fluid state, and the depression at the bottom of the rubber body 10 will also restore its original state. At the same time, the bent depression block 11 will retract, and the protruding column 12 will restore its original state. Finally, the test ball 15 with qualified test size can be taken out.
