When testing the hardness of ceramic grinding balls, the pressure head at the top of the testing device comes into contact with the ceramic grinding ball, but because the bottom surface of the ceramic grinding ball is arc-shaped, it is easy for it to roll on the testing table, making it difficult for the pressure head to press firmly against the grinding ball, thus making it difficult to test the hardness of the ceramic grinding ball.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0031] The present invention provides the following embodiments.

[0032] Example 1

[0033] This invention provides a ceramic grinding ball detection device, such as... Figure 1As shown, it includes a U-shaped shell 1, with a detection cavity at the upper end of the U-shaped shell 1, a ball-in-the-hole mechanism on the upper side of the detection cavity, the ball-in-the-hole mechanism being connected to the appearance inspection mechanism, the appearance inspection mechanism being connected to the hardness inspection mechanism, and the hardness inspection mechanism being located at the lower end of the detection cavity.

[0034] A method for testing ceramic grinding balls includes the following steps:

[0035] Step 1: The ceramic grinding ball 49 to be inspected is fed into the appearance inspection mechanism through the ball-infeeding mechanism;

[0036] Step 2: The diameter of the ceramic grinding ball 49 to be inspected is inspected by an appearance inspection agency;

[0037] Step 3: After the diameter of the ceramic grinding ball 49 to be tested is measured, it automatically enters the hardness testing mechanism under the action of gravity for hardness testing.

[0038] The beneficial effects of the above technical solution are as follows:

[0039] The feeding mechanism is used to feed the ceramic grinding balls 49 to be tested into the appearance inspection mechanism. The appearance inspection mechanism can detect the diameter of the ceramic grinding balls 49 to be tested, which solves the technical problem that existing ceramic grinding ball testing devices cannot detect the size of the grinding balls, making it impossible for users to know the specific size of the grinding balls. After the diameter is detected, the ceramic grinding balls 49 to be tested enter the hardness testing mechanism for hardness testing. The hardness testing mechanism is equipped with a positioning sleeve. When the hardness testing mechanism is working, the positioning sleeve first positions the ceramic grinding balls 49 to be tested, and then the pressure head is pressed against the ceramic grinding balls 49 to be tested for hardness testing. The positioning sleeve can prevent the ceramic grinding balls 49 to be tested from rolling. This solves the technical problem that when the pressure head of the testing device is pressed against the ceramic grinding ball, the bottom surface of the ceramic grinding ball is arc-shaped and it is easy to roll on the testing table, making it difficult for the pressure head to press against the grinding ball, thus making it difficult to test the hardness of the ceramic grinding ball.

[0040] Example 2

[0041] Based on Example 1, such as Figures 1-4 As shown, the feeding mechanism includes an inclined ball shell 3, which is installed on the upper right side of the detection chamber. The upper end of the ball shell 3 is provided with a ball groove 4, and the rear end of the ball groove 4 is connected to the ball hole 7. The ball hole 7 is disposed through the rear end of the ball shell 3. The ball hole 7 is correspondingly disposed with the arc-shaped end of the guide ball block 6, and the guide ball block 6 and the ball groove 4 are correspondingly matched.

[0042] The vertical end of the guide block 6 is fixedly connected to the mounting block 5. The mounting block 5 passes through the sliding cavity at the left end of the U-shaped shell 1 and is fixedly connected to the telescopic rod 2. The mounting block 5 is slidably connected to the sliding cavity, and the telescopic rod 2 is fixedly connected to the left end of the U-shaped shell 1.

[0043] The appearance inspection mechanism includes a connecting pipe 18, the horizontal end of which is fixedly connected to the rear end of the ball shell 3, the vertical end of which is fixedly connected to the upper end of the detection shell 20, the detection shell 20 is fixedly installed at the rear end of the detection cavity, the lower end of which is fixedly connected to a connecting pipe 20, a through hole 22 is provided through the middle of the detection shell 20, a connecting cavity 19 is provided inside the connecting pipe 18, and a connecting cavity 2 is provided inside the connecting pipe 20. The ball hole 7, the connecting cavity 19, the through hole 22 and the connecting cavity 2 are connected in sequence. The ball hole 7, the connecting cavity 19, the through hole 22 and the connecting cavity 2 are used to transmit ceramic grinding balls 49. The center of the vertical end of the connecting cavity 19 and the center of the through hole 22 are on the same vertical line. A number of elastic guide plates 48 are evenly distributed around the vertical end of the connecting cavity 19, and the number of elastic guide plates 48 are correspondingly installed at the upper end of the through hole 22.

[0044] The inside of the detection shell 20 is evenly provided with several opening slots around the through hole 22, and the opening slots are connected to the through hole 22. The opening slots are slidably connected to the contact block 24. A spring 21 is fixed between the opening slot and the vertical end of the contact block 24. A distance sensor 23 is installed in the opening slot. The distance sensor 23 is set correspondingly to the contact block 24. The inclined end of the contact block 24 is in contact with the ceramic grinding ball 49.

[0045] The beneficial effects of the above technical solution are as follows:

[0046] When testing the ceramic grinding ball 49 to be tested, it is first placed into the ball inlet groove 4. Due to the inclined setting of the ball inlet shell 3, the ceramic grinding ball 49 rolls downward under the action of gravity. The guide block 6 guides the movement of the ceramic grinding ball 49, allowing it to enter the connecting pipe 18 through the ball inlet hole 7. A buffer pad can be installed on the arc-shaped end of the guide block 6 to buffer the ceramic grinding ball 49, slowing down its speed and preventing it from being tested. If the ceramic grinding balls 49 move too fast, they may wear or deform the connecting pipe 18 or the ceramic grinding balls 49 due to excessive impact during contact with the connecting pipe 18. By setting the telescopic rod 2, the guide ball block 6 can be moved upward, thereby changing the distance between the guide ball block 6 and the ball inlet groove 4. This allows the smaller ceramic grinding balls 49 to pass directly through the gap between the guide ball block 6 and the ball inlet groove 4, while the larger ceramic grinding balls 49 enter the connecting pipe 18, thus adding the function of simple screening of the ceramic grinding balls 49.

[0047] After the ceramic grinding ball 49 to be tested enters the connecting pipe 18, it moves along the connecting cavity 19. The elastic guide plate 48 guides and corrects the movement of the ceramic grinding ball 49 to be tested, so that after passing the elastic guide plate 48, the center of the ceramic grinding ball 49 to be tested is on the same vertical line as the center of the through hole 22. After the ceramic grinding ball 49 to be tested enters the through hole 22, it contacts the inclined end of the contact block 24. After pushing the contact block 24 into the opening groove, the spring 21 is compressed. The setting of the spring 21 allows the contact block 24 to return to its original position after the ceramic grinding ball 49 to be tested disengages from the contact block 24.

[0048] Distance sensor 23 is a miniature laser distance sensor, model VL53L. Distance sensor 23 can detect the moving distance of contact block 24. Specifically, the distance sensor detects the distance between contact block 24 and the opening slot. The detection value of distance sensor 23 is at its maximum when contact block 24 is not in contact with the ceramic grinding ball 49 to be detected, and at its minimum when contact block 24 is in contact with the ceramic grinding ball 49 and cannot move. The difference between the maximum and minimum values ​​of distance sensor 23 is recorded as X, where X is the distance between the contact block and the minimum value. The moving distance of 24 is denoted as H, the distance between the symmetrically arranged contact blocks 24 is denoted as D, and the diameter of the ceramic grinding ball 49 to be detected is denoted as D. D is the sum of the difference between the maximum and minimum values ​​detected by the symmetrically arranged distance sensors 23 and the distance between the symmetrically arranged contact blocks 24, i.e., D = 2X + H. The symmetrically arranged distance sensors 23 are set as a group. The arrangement of multiple groups of distance sensors 23 can detect the ceramic grinding ball 49 to be detected along different directions of the horizontal plane, thereby obtaining the diameter value of the ceramic grinding ball 49 to be detected along different directions of the horizontal plane.

[0049] Similarly, when the ceramic grinding ball 49 to be tested passes through the through hole 22, the roundness of the ceramic grinding ball 49 to be tested can be detected by several distance sensors 23 along different horizontal circular surfaces in the vertical direction. Specifically, it is determined whether the moving distance of the contact block 24 detected by several distance sensors 23 is the same.

[0050] Example 3

[0051] Based on Example 2, such as Figure 1 , Figures 5-6As shown, the hardness testing mechanism includes a testing shell 8, and a testing cavity 37 is provided inside the testing shell 8. A connecting pipe 2 50 passes through the rear end of the testing cavity 37 and enters the testing cavity 37. The connecting cavity 2 is correspondingly located on the upper rear side of the placement groove 17. The placement groove 17 is located on the upper end of the support mold 16. A support platform 15 is provided at the lower end of the testing cavity 37. The support mold 16 is installed on the upper end of the support platform 15. A pressure sensor is installed between the support mold 16 and the support platform 15. The placement groove 17 is used to place ceramic grinding balls 49.

[0052] The upper end of the detection shell 8 is fixedly connected to the fixed end of the hydraulic rod 9. The movable end of the hydraulic rod 9 passes through the upper end of the detection shell 8 and enters the detection cavity 37. The movable end of the hydraulic rod 9 is fixedly connected to the sliding plate 10 and the detection pressure head 13. The movable end of the hydraulic rod 9 is slidably connected to the sliding hole 25 in the positioning sleeve 14. The positioning sleeve 14 is correspondingly set at the upper end of the placement groove 17. The positioning sleeve 14 is fixedly connected to the sliding plate 12. The sliding plate 10 and the sliding plate 12 are both slidably set on the upper side of the detection cavity 37. Several springs 11 are fixedly provided between the sliding plate 10 and the sliding plate 12. The lower end of the positioning sleeve 14 is provided with a positioning hole 26. The upper end of the positioning sleeve 14 is provided with a sliding hole 25. The sliding hole 25 and the positioning hole 26 are connected vertically. A rubber ring is provided in the positioning hole 26. The inner diameter of the rubber ring is larger than the diameter of the sliding hole 25. The rubber ring is in corresponding contact with the ceramic grinding ball 49.

[0053] The beneficial effects of the above technical solution are as follows:

[0054] The specific structure for installing a pressure sensor between the support mold 16 and the support platform 15 is as follows: a sliding column is set at the lower end of the support mold 16, and a sliding port is set at the upper end of the support platform 15. A pressure sensor is installed in the sliding port, and the sliding port is slidably connected to the sliding column. Under the action of gravity, the ceramic grinding ball 49 to be tested passes through the through hole 22 and then through the connecting cavity 2 inside the connecting pipe 20 and falls onto the placement groove 17. Then, the hydraulic rod 9 is activated. The movable end of the hydraulic rod 9 drives the sliding plate 10 and the detection pressure head 13 to move. The sliding plate 10 drives the sliding plate 12 to move through the spring 21. The sliding plate 12 drives the positioning sleeve 14 to move. When the positioning hole 26 in the positioning sleeve 14 contacts the ceramic grinding ball 49 to be tested, the rubber ring in the positioning hole 26 squeezes and fixes the upper side of the ceramic grinding ball 49 to be tested. This prevents the ceramic grinding ball 49 to be tested from rolling. The rubber ring protects the ceramic grinding ball 49. At this time, the positioning sleeve 14 cannot move downwards, and the sliding plate 12 cannot move either. As the sliding plate 10 continues to move, the spring 11 is compressed. At the same time, the detection head 13 extends out of the sliding hole 25 and the inner hole of the rubber ring to squeeze the ceramic grinding ball 49 to be tested. The ceramic grinding ball 49 drives the support mold 16 to move downwards. The support mold 16 drives the sliding column to squeeze the pressure sensor. The pressure sensor can detect the squeezing force on the ceramic grinding ball 49 to be tested (refer to CN202020066114 - a building material hardness testing device). The hardness of the ceramic grinding ball 49 to be tested is detected by the squeezing force that the ceramic grinding ball 49 to be tested can withstand.

[0055] Example 4

[0056] Based on embodiment 3, a stabilizing mechanism is also included. The stabilizing mechanism includes threaded rods 41 symmetrically arranged on the left and right sides of the detection cavity 37. The threaded rods 41 are driven by a driving mechanism. The threaded section of the threaded rods 41 is threadedly connected to the threaded block 31. The threaded block 31 is slidably connected to the lower side of the detection cavity 37. A movable cavity is provided at the end of the threaded block 31 away from the side of the detection cavity 37. A movable block 35 is slidably arranged in the movable cavity. A spring 34 is fixedly arranged between the movable cavity and the movable block 35. The end of the movable block 35 away from the spring 34 is fixedly connected to the connecting block 36. The connecting block 36 passes through the side of the movable cavity and enters the detection cavity 37 and is fixedly connected to the lower vertical end of the moving block 33. Fixed blocks 32 are symmetrically arranged on the front and rear sides of the upper inclined end of the moving block 33. The inclined end of the moving block 33 is slidably connected to the inclined end of the fixed block 32. The fixed block 32 is fixedly arranged at the side of the detection cavity 37.

[0057] The upper part of the movable block 33 is provided with a working groove 42 at the end away from the fixed block 32. The front and rear sides of the working groove 42 are symmetrically provided with rotating shafts 43. The rotating shafts 43 are fixedly connected to the rotating block 45. Torsion springs 40 are provided between the upper and lower ends of the rotating block 45 and the upper and lower ends of the working groove 42 respectively. The torsion springs 40 are sleeved on the rotating shafts 43. The rotating block 45 is fixedly connected to the mounting base 38. The mounting base 38 is rotatably connected to the ball 39. The ball 39 is in corresponding contact with the ceramic grinding ball 49. The middle part of the rotating block 45 is provided with an installation port. The installation port is provided with a gear 44. The gear 44 is fixedly connected to the middle part of the rotating shaft 43. The gears 44 on the front and rear sides are meshed with a rack 46. The rack 46 is slidably connected to the mating groove in the movable block 33. The mating groove is connected to the working groove 42. The end of the rack 46 away from the mating groove is fixedly connected to the clamping block 47.

[0058] The driving mechanism includes a driving cavity inside the detection housing 8, which is located on the lower side of the detection cavity 37. A motor 27 is installed on the left side of the driving cavity. The motor 27 is fixedly connected to the left pulley 29 via a motor shaft 28. The left pulley 29 is connected to the right pulley 29 via a conveyor belt 30. The pulleys 29 on both sides are fixedly connected to the cylindrical sections of the threaded rods 41 on both sides. The cylindrical sections of the threaded rods 41 pass through the upper end of the driving cavity and enter the detection cavity 37.

[0059] The beneficial effects of the above technical solution are as follows:

[0060] After the ceramic grinding ball 49 to be tested falls into the placement groove 17, the motor 27 is started. The motor 27 drives the left pulley 29 to rotate through the motor shaft 28. The left pulley 29 drives the right pulley 29 to rotate through the conveyor belt 30. When the left and right pulleys 29 rotate, they drive the left and right threaded rods 41 to rotate synchronously. When the threaded rods 41 rotate, they drive the threaded block 31 to move downward. The threaded block 31 drives the moving block 33 to move downward. When the moving block 33 moves, under the guidance of the inclined end of the fixed block 32, the moving block 33 moves towards the supporting mold 16. The moving block 33 drives the connecting block 36 to move. The connecting block drives the movable block 35 to slide along the movable cavity, which guides the movement of the moving block 33. The setting of the spring 34 makes the movement of the moving block 33 stable. As the moving block 33 drives the rotating block 45 to move downward and towards the supporting mold 16, the rolling ball 39 on the rotating block 45 contacts the ceramic grinding ball 49 to be tested and moves towards the supporting mold 16. The ceramic grinding ball 49 being tested moves towards its center. During this process, the rotating block 45 rotates towards the side away from each other. The rotating block 45 drives the rotating shaft 43 to rotate, and the torsion spring 40 deforms. The rotating shaft 43 drives the gear 44 to rotate, and the gear 44 drives the rack 46 to move. The rack 46 drives the clamping block 47 to move towards the ceramic grinding ball 49 to be tested. The clamping block 47 selects a rubber block to protect the ceramic grinding ball 49 to be tested until the clamping block 47 and the ceramic grinding ball 49 to be tested are pressed into contact. At this time, the rolling balls 39 on the front and rear sides limit the front and rear sides of the ceramic grinding ball 49 to be tested, and the clamping blocks 47 on the left and right sides limit the left and right sides of the ceramic grinding ball 49 to be tested, so that the ceramic grinding ball 49 to be tested can be more stably placed on the placement groove 17, and the ceramic grinding ball 49 can also be positioned directly below the positioning sleeve 14, which facilitates the subsequent positioning contact between the positioning sleeve 14 and the ceramic grinding ball 49 to be tested.

[0061] When the ceramic grinding ball 49 to be tested is released, the threaded rod 41 is rotated in the opposite direction, so that the moving block 33 moves upward. Under the elastic action of the torsion spring 40, the rolling ball 39 and the clamping block 47 return to their original positions. The stabilizing mechanism is used to assist the positioning sleeve 14 in positioning the ceramic grinding ball 49 to be tested. Specifically, the stabilizing mechanism is first used to clamp and fix the ceramic grinding ball 49 to be tested, and then the positioning sleeve 14 is used to position the ceramic grinding ball 49 to be tested. The stabilizing mechanism is always located on the lower side of the positioning sleeve 14 to avoid mutual interference between the two. Through the setting of the stabilizing mechanism and the joint action of the positioning sleeve 14, the ceramic grinding ball 49 to be tested can remain stationary during the hardness testing process, avoiding deformation of the rubber ring in the positioning sleeve 14, which would cause the ceramic grinding ball 49 to be tested to shake slightly, thus affecting the test results.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
