[0006] Preferably, the vertical pushing wheel is covered with a rubber ring, and the parallel pushing wheel is covered with a rubber ring. In the prior art, since the steel ball is usually made of metal material, its surface is smooth and the friction coefficient is relatively low. However, when the surface of the steel ball is stained, problems will follow. During the detection process, the steel ball needs to be placed in a special groove. If the surface is stained, the dirt will significantly increase the friction between the steel ball and the groove wall. In the detection equipment, the vertical pushing wheel and the parallel pushing wheel are responsible for pushing the steel ball to rotate to detect the integrity of its surface. However, when the pushing force of the pushing wheel is less than the friction force caused by the stain, the pushing wheel cannot effectively drive the steel ball to rotate. In this case, the steel ball is difficult to complete the rotating action as expected, resulting in the occurrence of skidding. Because of the existence of skidding, the control ability of the machine part to the steel ball is weakened, so that the position of the steel ball in the groove is unstable, and abnormal friction is prone to occur. Such abnormal friction not only affects the accuracy of the detection process, but also causes wear or scratches on the surface of the steel ball. Once the surface of the steel ball is worn or damaged, the quality and performance of the steel ball as a motor bearing will be greatly reduced, directly leading to a decrease in yield. In view of such problems, the utility model adopts the installation of a rubber ring to solve the problem, realizes the increase of the diameter of the vertical pushing wheel and the parallel pushing wheel through the rubber ring, so that they can be slightly higher than the inner wall groove of the fixed measuring part. When the steel ball is embedded, the rubber ring is compressed and deformed, greatly increasing the contact area with the surface of the steel column, and greatly increasing the friction coefficient of the vertical pushing wheel and the parallel pushing wheel. The friction between the steel column is increased, which is more convenient for pushing the steel ball to slide while preventing scratching the surface of the steel ball, achieving the effect of improving work efficiency.

[0007] Preferably, the top of the fixed measuring member is fixed with a fan member, and the top of the moving side member is fixed with a fan member. In the prior art, the sharp edges on the top of the fixed measuring member and the moving side member are intended to scrape off the stains attached to the surface of the steel ball. In theory, this design can effectively clean the steel ball and ensure the surface quality. However, in actual operation, this process is not risk-free and has side effects. When the sharp edges scrape off the stains on the surface of the steel ball, the stains are often ground into fine powder particles. These particles are not only small but also easy to spread and gradually accumulate on the top of the fixed measuring member and the moving side member. As the detection process continues, more and more stain powder accumulates on the top of the device, forming an unstable "dirt mountain". The seriousness of this problem lies in that once the powder-like stains accumulate to a certain extent, they will collapse and fall into the groove of the fixed measuring member and the moving side member. The sudden large amount of stains falling into the groove will greatly increase the friction between the steel ball in the groove and the fixed measuring member and the moving side member. Under normal operating conditions, the push wheel relies on appropriate friction to push the steel ball to rotate. However, in the case of abnormally increased friction, the pushing force of the push wheel becomes insufficient to maintain the normal rotation of the steel ball. Therefore, the steel ball cannot complete the rotation as expected, and even skidding occurs, resulting in a failed detection process. More seriously, these stain powders falling into the groove will generate additional friction on the surface of the steel ball. This abnormal friction will leave scratches on the surface of the steel ball, damaging its appearance and performance. For steel balls used as motor bearings, surface quality is crucial, and any scratches or wear will result in rejection, thereby reducing the overall yield. To solve such problems, the utility model adopts the installation of a fan member, which realizes the built-in motor and fan blades inside the fan member. After the staff starts it, due to the limitation of the air outlet hole, a large amount of wind will be generated on the top of the fixed measuring member and the moving side member, so that the scraped stains are blown away, preventing stain accumulation and improving the yield.

[0008] Preferably, the circumferential surface of the rubber ring is provided with a plurality of friction grooves arranged in a circle, which increases the friction and improves the working efficiency of the device.

[0009] Preferably, the bottom of the workbench is fixed with a rubber pad to provide shock absorption, reduce device noise, and improve user experience.

[0010] Preferably, the bottom of the rubber pad is provided with anti-skid grooves to prevent the device from slipping and improve the stability of the device.

[0011] Preferably, the top edge of the workbench is chamfered to reduce the self-weight of the device and reduce transportation costs.

[0012] Beneficial effects:

[0013] 1. In existing technology, before being used as motor bearings, automated steel balls must undergo visual inspection to ensure they are free of scratches, bulges, or defects. However, current inspection equipment faces a significant problem: when the steel ball surface is covered with dust, stains, or adhesive residue rather than having inherent quality issues, the inspection instruments often struggle to accurately distinguish between these surface contaminants and actual quality problems. This limitation makes it difficult for the machine to complete the inspection task independently, necessitating manual intervention for cleaning. This not only increases the error rate but also significantly increases the workload of the workers. In this situation, production efficiency is reduced, and the quality stability of the final product is affected. To address this problem, this utility model solves it by installing a moving side component. When workers need to inspect the appearance of the steel ball, they place the steel ball into the ball-limiting groove. Then, an external motor drives a threaded rod to rotate, and the threaded connection pulls the moving side component towards the fixed test piece until they are in contact. The two components work together to confine the steel ball within the ball-limiting groove. When the moving part moves, it pulls the convex sliding part to slide in the convex sliding groove. The cooperation between the convex sliding part and the convex sliding groove can better restrict the moving part and prevent it from shaking. When the moving part is in contact with the fixed measuring part, the keyed connecting groove of the nested gear is also fitted into the keyed connecting column, so that the two are keyed together, and the nested gear meshes with the driving gear. The operator can control the rotation of the vertical push wheel and the parallel push wheel by controlling the external motor and the top motor. When the two rotate simultaneously or individually, the steel ball in the ball-limiting groove will rotate in different directions due to friction. At the same time, due to the cooperation and shielding of the fixed measuring part and the moving part, the surface of the steel ball is divided, allowing the operator to mark the surface of the steel ball with a CCD device. By making the detection convenient, and by letting the steel ball rotate in the groove, when the surface of the steel ball is dirty, the dirt will be scraped off when it passes the sharp edge of the fixed measuring part and the moving part because it is higher than the surface of the steel ball. This reduces the misjudgment of the steel ball by the detection equipment, thereby improving work efficiency, increasing the yield, and improving the accuracy of the equipment.

[0014] 2、In the prior art, since the steel ball is usually made of metal material, its surface is smooth and the friction coefficient is relatively low, however, when there is dirt on the surface of the steel ball, problems will follow, in the detection process, the steel ball needs to be placed in a special groove, if the surface has dirt, these dirt will significantly increase the friction between the steel ball and the groove wall, in the detection equipment, the vertical push wheel and the parallel push wheel are responsible for pushing the steel ball to rotate to detect the integrity of its surface, however, when the pushing force of the push wheel is less than the friction force caused by the dirt, the push wheel cannot effectively drive the steel ball to rotate, in this case, the steel ball is difficult to complete the rotation as expected, resulting in the occurrence of skidding phenomenon, because of the existence of skidding phenomenon, the control ability of the machine part to the steel ball is weakened, so that the position of the steel ball in the groove is unstable, and abnormal friction is easy to occur, such abnormal friction not only affects the accuracy of the detection process, but also causes wear or scratch on the surface of the steel ball, once the surface of the steel ball is worn or damaged, the quality and performance of the steel ball as a motor bearing will be greatly reduced, which directly leads to the decrease of the yield, in view of such problems, the utility model adopts the mode of installing rubber ring to solve the problem, realizes that the diameter of the vertical push wheel and the parallel push wheel is increased through the rubber ring, so that they can be slightly higher than the inner wall groove of the fixed measuring part, when the steel ball is embedded, the rubber ring is compressed and deformed, greatly increasing the contact area with the surface of the steel column, at the same time, the friction coefficient of the vertical push wheel and the parallel push wheel is greatly increased, the friction force with the steel column is increased, which is more convenient for pushing the steel ball to slide, prevents the surface of the steel ball from being scratched, and achieves the effect of improving the working efficiency.

[0015] 3、In the prior art, in the automatic detection process of steel balls, the sharp edges on the top of the fixed measuring member and the moving member are intended to scrape off the stains attached to the surface of the steel balls. In theory, this design can effectively clean the steel balls and ensure the surface quality thereof. However, in actual operation, this process is not risk-free and has side effects. When the sharp edges scrape off the stains on the surface of the steel balls, the stains are often ground into fine powder particles. These particles are not only fine but also easy to spread and gradually accumulate on the top of the fixed measuring member and the moving member. As the detection process continues, more and more stain powder accumulates on the top of the equipment to form an unstable "dirt mountain". The seriousness of this problem lies in that, once the stain powder accumulates to a certain extent, it will collapse and fall into the groove of the fixed measuring member and the moving member. The sudden large amount of stains falling into the groove greatly increases the friction between the steel balls in the groove and the fixed measuring member and the moving member. Under normal operating conditions, the push wheel relies on appropriate friction to push the steel balls to rotate. However, in the case of abnormally increased friction, the pushing force of the push wheel becomes insufficient to maintain the normal rotation of the steel balls. Therefore, the steel balls cannot complete the rotation as expected and even skid, resulting in a failed detection process. More seriously, the stain powder falling into the groove produces additional friction on the surface of the steel balls. This abnormal friction leaves scratches on the surface of the steel balls, damaging the appearance and performance thereof. For steel balls used as motor bearings, the surface quality is crucial. Any scratches or wear will cause the steel balls to be unqualified, thereby reducing the overall yield. To solve such problems, the utility model adopts the installation of a fan member to internally arrange a motor and a fan blade. After the staff starts the fan member, due to the limitation of the air outlet hole, a large amount of wind is generated on the top of the fixed measuring member and the moving member, so that the scraped stains are blown away, preventing the accumulation of stains and improving the yield.

When they rotate simultaneously or individually, they will cause the steel ball in the groove 202 to rotate in different directions due to friction. At the same time, due to the combination and shielding of the fixed measuring element 2 and the moving side element 201, the surface of the steel ball is divided, so that the staff can mark the surface of the steel ball through the ccd device. Through detection convenience, by rotating the steel ball in the groove, when the surface of the steel ball is stained, the stain will be higher than the surface of the steel ball, so that it is scraped off when passing through the sharp edge at the top of the fixed measuring element 2 and the moving side element 201, thereby reducing the misjudgment of the detection equipment to the steel ball, achieving the effect of improving work efficiency, increasing yield, and improving equipment accuracy. The vertical push wheel 207 is covered with a rubber ring 3, and the parallel push wheel 203 is covered with a rubber ring 3. Since the steel ball is usually made of metal material, its surface is smooth and the friction coefficient is relatively low. However, when the surface of the steel ball is stained, the problem comes with it. During the detection process, the steel ball needs to be placed in a specific groove. If the surface is stained, these stains will significantly increase the friction between the steel ball and the groove wall. In the detection equipment, the responsibilities of the vertical push wheel 207 and the parallel push wheel 203 are to push the steel ball to rotate to detect the integrity of its surface. However, when the pushing force of the push wheel is less than the friction caused by the stain, the push wheel cannot effectively drive the steel ball to rotate. In this case, the steel ball is difficult to complete the rotation as expected, resulting in the occurrence of skidding. Because of the existence of skidding, the control ability of the machine part to the steel ball is weakened, so that the position of the steel ball in the groove is unstable, and abnormal friction is easily caused. This abnormal friction not only affects the accuracy of the detection process, but also causes wear or scratches on the surface of the steel ball. Once the surface of the steel ball is worn or damaged, its quality and performance as a motor bearing will be greatly reduced, directly leading to a decrease in yield. The installation of the rubber ring 3 solves the problem, which increases the diameter of the vertical push wheel 207 and the parallel push wheel 203 through the rubber ring 3, so that they can be slightly higher than the inner wall groove of the fixed measuring element 2. When the steel ball is embedded, the rubber ring 3 is compressed and deformed, greatly increasing the contact area with the steel column surface, and greatly increasing the friction coefficient of the circumference of the vertical push wheel 207 and the parallel push wheel 203, increasing the friction with the steel column. At the same time, it prevents scratching the surface of the steel ball, achieving the effect of improving work efficiency.

[0030] The top of the fixed measuring element 2 is fixed with a fan element 4, and the top of the moving side element 201 is fixed with a fan element 4. In the automatic detection process of steel balls, the sharp edges at the top of the fixed measuring element 2 and the moving side element 201 are intended to scrape off the stains attached to the surface of the steel balls. In theory, this design can effectively clean the steel balls and ensure the surface quality. However, in actual operation, this process is not without risks and side effects. When the sharp edges scrape off the stains on the surface of the steel balls, these stains are often ground into tiny powder particles. These particles are not only small but also easy to spread and will gradually accumulate on the top of the fixed measuring element 2 and the moving side element 201. As the detection process continues, more and more stain powder accumulates on the top of the device, forming an unstable "dirt mountain". The seriousness of this problem lies in that once the powder-like stains accumulate to a certain extent, they will collapse and fall into the groove of the fixed measuring element 2 and the moving side element 201. The sudden large amount of stains falling into the groove will greatly increase the friction between the steel balls in the groove and the fixed measuring element 2 and the moving side element 201. Under normal operating conditions, the push wheel relies on appropriate friction to push the steel balls to rotate, but in the case of abnormal increase in friction, the pushing force of the push wheel becomes insufficient to maintain the normal rotation of the steel balls. Therefore, the steel balls cannot complete the rotation as expected, and even skidding occurs, resulting in a failed detection process. More seriously, these stain powders falling into the groove will produce additional friction on the surface of the steel balls. This abnormal friction will leave scratches on the surface of the steel balls, damaging their appearance and performance. For steel balls used as motor bearings, surface quality is crucial, and any scratches or wear will result in their rejection, thereby reducing the overall yield. The installation of the fan element 4 solves this problem by achieving the internal installation of the motor and the fan blade in the fan element 4. After the staff starts it, due to the limitation of the air outlet hole, it will generate a large wind force on the top of the fixed measuring element 2 and the moving side element 201, so that the scraped stains are blown away, preventing the accumulation of stains and achieving the effect of improving the yield. The circumferential array of the rubber ring 3 is provided with a friction increasing groove 301 to increase the friction and improve the working efficiency of the equipment. The bottom of the workbench 1 is fixed with a rubber pad 102 to provide shock absorption, reduce equipment noise and improve user experience. The bottom of the rubber pad 102 is provided with an anti-skid groove to prevent the equipment from slipping and improve the stability of the equipment. The top edge of the workbench 1 is provided with a chamfer 103 to reduce the self-weight of the equipment and reduce transportation costs.

[0031] The utility model discloses a working principle: when the staff needs to detect the appearance of steel ball, put the steel ball into the ball limit nest groove 202, then drive screw rod 205 rotation through the external motor, and the screw connection pulls the dynamic side piece 201 and moves to the direction of approaching fixed measuring piece 2, until the adhesion, and the combination of both restricts the steel ball in the ball limit nest groove 202, and when the dynamic side piece 201 moves, pull the convex slide piece 2010 in the convex slide groove 209, and the combination of convex slide piece 2010 and convex slide groove 209 can better restrict the dynamic side piece 201, prevent it from shaking, when the dynamic side piece 201 and fixed measuring piece 2 adhere, the key nest connection groove 2013 of nested gear 2012 also fits into key nest connection column 2014, so that the key connection of both, and nested gear 2012 and driving gear 2015 engage, and the staff can control the rotation of vertical push wheel 207 and parallel push wheel 203 through the control of external motor and top-mounted motor 206, when both rotate simultaneously or individually, the steel ball in the ball limit nest groove 202 will produce different direction rotation due to friction, and due to the combination of fixed measuring piece 2 and dynamic side piece 201 shielding, the surface of steel ball is divided, so that the staff can mark the surface of steel ball through ccd equipment, through the detection convenience, through the mode of making the steel ball rotate in the groove, when the surface of steel ball is stain, the stain will be scraped off when passing through the sharp edge of the top of fixed measuring piece 2 and dynamic side piece 201 due to being higher than the surface of steel ball, thereby reducing the misjudgment of detection equipment to steel ball.
