Description

Technical Field

[0001] This utility model belongs to the field of ceramic ball production technology, and in particular relates to a ceramic ball surface defect detection device. Background Technology

[0002] Ceramic balls are spheres made of ceramic materials. They are characterized by high hardness, good wear resistance, and strong corrosion resistance. They are used in industry for bearings and grinding media, and also in some high-end decorative items in daily life. Their manufacturing process is diverse, and quality inspection is crucial, especially the detection of surface defects.

[0003] Most ceramic ball surface defect detection devices have several drawbacks in use. For example, during inspection, the ceramic ball needs to be manually rotated and observed. When manually rotating the ball, it's difficult to ensure consistent angle and speed of rotation each time, leading to over-observation of some areas and under-observation of others when checking surface defects or other features. Furthermore, the distance between the ceramic ball and the observation lens varies depending on its size; for instance, smaller ceramic balls require a shorter distance for easier observation. Holding the observation lens can also cause operator fatigue, leading to decreased concentration and ultimately affecting the quality of the inspection. Therefore, we propose a ceramic ball surface defect detection device. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic ball surface defect detection device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a ceramic ball surface defect detection device, including a base and a fixing block, and further comprising:

[0006] Two fixing plates are fixedly installed on the top of the base. The fixing block is fixedly installed on the top of the base. The two fixing plates are located on both sides of the fixing block. A rotating column is rotatably installed on the side of the two fixing plates that are close to each other. A sliding column is slidably installed on the two rotating columns. A clamping plate is fixedly installed on the end of the two sliding columns that are close to each other.

[0007] Motor 1 is fixedly installed on one side of one of the fixed plates. The output shaft of motor 1 passes through one of the fixed plates and is fixedly connected to one of the rotating columns. A power cavity is opened in the base. Two sliding plates are slidably installed in the power cavity. The upper ends of the two sliding plates pass through the power cavity and are rotatably connected to the two sliding columns respectively.

[0008] A fixed column is fixedly installed on the top of the base and located on one side of the fixed block. A sliding strip is slidably installed inside the fixed column, and a magnifying glass is fixedly installed at one end of the sliding strip.

[0009] A drive assembly, located within the base, is used to drive two sliding plates to slide.

[0010] A limiting component is located inside a fixed post and is used to limit the position of the sliding bar.

[0011] In this technical solution, when ceramic balls need to be inspected, the ceramic balls are first placed on top of the fixed block. Through the set drive component, two sliding plates can be driven to slide and move closer to each other. The two sliding plates drive two sliding columns to slide and move closer to each other. The two sliding columns drive two clamping discs to slide and move closer to each other. The two clamping discs can clamp the ceramic balls. Then, motor one is started. Motor one is powered on and drives one of the rotating columns to rotate slowly. One of the rotating columns drives one of the sliding columns and one of the clamping discs to rotate slowly. One of the clamping discs drives the ceramic ball to rotate slowly. The ceramic ball drives another clamping disc, another sliding column, and another rotating column to rotate slowly. The ceramic ball rotates slowly and automatically, which makes it convenient for the staff to inspect the ceramic ball with a magnifying glass, ensuring that all defects on the surface of the ceramic ball can be detected, and it is also convenient to clamp ceramic balls of different sizes.

[0012] When it is necessary to adjust the distance between the magnifying glass and the ceramic ball, the operator can pull the slider up or down using the set limiting component. When the slider moves to the appropriate position, the setting limiting component can fix the position of the slider, making it convenient for the operator to adjust the position of the magnifying glass.

[0013] In the above technical solution, the driving component further includes:

[0014] Motor 2 is fixedly installed inside the power cavity. A disc is fixedly installed on the output shaft of Motor 2. Two connecting rods are rotatably installed on the top of the disc. One end of each connecting rod is rotatably connected to two sliding plates. The disc is rotatably connected to the power cavity.

[0015] In this technical solution, when it is necessary to test the ceramic ball, the ceramic ball is first placed on top of the fixed block, and then the second motor is started. The second motor is powered on and drives the disc to rotate. The disc pulls the two connecting rods to rotate. The two connecting rods pull the two sliding plates to slide and move closer to each other. The two sliding plates drive the two sliding columns to slide and move closer to each other. The two sliding columns drive the two clamping discs to slide and move closer to each other. The two clamping discs can clamp the ceramic ball.

[0016] In the above technical solution, the limiting component further includes:

[0017] A sliding groove is formed inside a sliding strip. A sliding rod is slidably installed inside the sliding groove. One end of the sliding rod is fixedly installed with several springs that are fixed to the inner wall of the sliding groove. The other end of the sliding rod passes through the sliding groove and extends to the outside. Guide grooves are symmetrically formed at the bottom of the sliding rod. Guide posts are slidably installed in both guide grooves. Limit blocks are fixedly installed at the bottom ends of both guide posts.

[0018] Several grooves are formed in the fixed column and are located on both sides of the sliding strip. The ends of the two limiting blocks that are far apart from each other pass through the sliding groove and extend into the corresponding grooves. One end of the limiting block is inserted into the corresponding groove, and both limiting blocks are slidably connected to the sliding groove.

[0019] In this technical solution, when it is necessary to adjust the distance between the magnifying glass and the ceramic ball, the sliding rod is first pushed towards the spring. At the same time, several springs are compressed and contracted. The sliding rod drives two guide posts to slide and move closer to each other through two guide grooves. The two guide posts drive two limit blocks to slide and move closer to each other. After the two limit blocks disengage from two of the grooves, the operator pulls the sliding bar to rise or fall. Finally, the sliding rod is released. Under the rebound force of several springs, the sliding rod slides outward. The sliding rod drives two guide posts to slide and move away from each other through two guide grooves. The two guide posts drive two limit blocks to slide and move away from each other. Finally, the ends of the two limit blocks that move away from each other are inserted into the corresponding grooves, which can fix the position of the sliding bar and facilitate the operator to adjust the position of the magnifying glass.

[0020] In the above technical solution, the output shaft of the motor is rotatably connected to one of the fixed plates.

[0021] In this technical solution, it is ensured that the output shaft of motor one can rotate within one of the fixed plates.

[0022] In the above technical solution, further, several of the grooves are distributed at equal intervals within the fixed column.

[0023] In this technical solution, it is ensured that the magnifying glass can be moved to any position.

[0024] In the above technical solution, the guide groove is further arranged at an angle.

[0025] In this technical solution, the sliding rod is ensured to drive the two guide posts to slide through the two guide grooves respectively.

[0026] In the above technical solution, the magnifying glass is further positioned directly above the fixed block.

[0027] In this technical solution, it is ensured that the magnifying glass can be used to observe the ceramic ball.

[0028] In the above technical solution, the limiting block and the corresponding guide post are integrally formed.

[0029] In this technical solution, the stability of the limiting block and guide post during use is ensured.

The two clamping discs can clamp the ceramic ball. Then, the first motor is started. The first motor is powered on and drives one of the rotating columns to rotate slowly. One of the rotating columns drives one of the sliding columns and one of the clamping discs to rotate slowly. One of the clamping discs drives the ceramic ball to rotate slowly. The ceramic ball rotates automatically and slowly, which makes it convenient for the staff to inspect the ceramic ball through a magnifying glass, ensuring that all defects on the surface of the ceramic ball can be detected, and it is convenient to clamp ceramic balls of different sizes.
