Description

Technical Field

[0001] The invention relates to the technical field of steel ball detection, and in particular to a casting steel ball hardness detection device and detection method. Background Art

[0002] Cast steel balls are made by casting and smelting methods. The density of this cast steel ball is relatively low. Therefore, it is mainly suitable for industries with low grinding precision requirements and low wear and tear, such as metallurgical mines, slag, etc. In the production process of cast steel balls, their hardness needs to be tested. The purpose of this is to know whether the produced steel balls meet the use standards, and the Rockwell hardness tester is usually used for hardness testing.

[0003] However, when testing the hardness of a steel ball, it is easy to slide on the test bench due to its shape. Therefore, during testing, a clamping mechanism is generally installed on the test bench to clamp and limit the steel ball. The Rockwell hardness tester itself does not have the corresponding clamping function, and its functionality is poor. In addition, steel balls with different diameters require clamping mechanisms of different specifications to be fixed, which makes the actual operation more troublesome. In addition, during batch testing, after each steel ball is tested, it is necessary to remove the tested steel ball and place it in a designated container, and then take out the next steel ball and re-fix it before continuing the hardness test. This makes the testing process discontinuous, the degree of automation is low, and it consumes more energy of the staff.

[0004] Therefore, it is necessary to provide a new casting steel ball hardness detection device and detection method to solve the above technical problems. Summary of the invention

[0026] In this embodiment: In the initial state, the output shafts of the first cylinder 13, the third cylinder 33 and the fourth cylinder 44 are all in the extended state; When the hardness test of the steel ball is required, the suitable storage hopper 29 is first adjusted according to the diameter of the steel ball. During the adjustment, the driving motor is directly started, and its output shaft drives the second gear to rotate. The engagement between the second gear and the third gear can drive the shaft rod 27 to rotate. During the rotation, the rotating disk 28 also rotates together. After the storage hopper 29 of the corresponding model is rotated to the top of the feed pipe 38, the driving motor is turned off, and then the cast steel balls of the corresponding diameter are poured into the storage hopper 29. While pouring, a part of the steel balls directly enter the straight tube in the lower half of the storage hopper 29 and are stacked one by one. Subsequently, the first servo motor is started in the positive direction, and its output shaft drives the first bidirectional lead screw 11 to rotate, and the first transverse slide 12 and the second transverse slide 15 are close to each other, so that the first transverse baffle 14 and the second transverse baffle 17 are also close to each other. At this time, the distance between the two is observed. When the distance between the two is slightly larger than the diameter of the steel ball, the first servo motor is turned off, and the second servo motor is immediately started in the positive direction. In the same way as above, the distance between the two longitudinal baffles 22 is adjusted to be slightly larger than the diameter of the steel ball. Subsequently, the two motors 41 are started first, and the output shafts of the two motors 41 respectively drive the corresponding first gears 42 to rotate. At this time, the meshing between the first gear 42 and the arc-shaped toothed bar 43 is utilized to make the two discharge adjustment plates 40 rotate at the same time, and the rotation directions are opposite to each other, so that the opening between the two discharge adjustment plates 40 gradually becomes smaller. When the discharge opening size is slightly larger than the diameter of the steel ball, the motor 41 is turned off. Then, the output shaft of the fourth cylinder 44 is started to retract, and driven by the folding rod 45, the receiving box 37 and the rotating disk 28 move toward the direction of the Rockwell hardness tester 1, and finally the receiving box 37 moves to the top of the testing table 9, and then, the output shaft of the corresponding third cylinder 33 is started to retract, so that the corresponding isolation sheet 35 is inserted into the storage hopper 29, thereby separating the bottom steel ball from all the steel balls above, and then, the corresponding third servo motor is started, and its output shaft drives the corresponding linkage shaft 31 to rotate, and the corresponding sealing plate 32 gradually rotates open. When the sealing plate 32 is completely rotated open, the bottom of the corresponding storage hopper 29 is opened, and the bottom steel ball will directly fall into the receiving box 37 through the feed pipe 38, and then continue to roll with inertia, and smoothly pass through the opening between the two discharge adjustment plates 40 and fall onto the testing table 9, and then the output shaft of the fourth cylinder 44 is started to extend, and the receiving box 37 is brought back to its original position; Subsequently, the first servo motor is started, and the first transverse baffle 14 and the second transverse baffle 17 are moved closer to each other again until the two gently clamp the steel ball, and the first servo motor is turned off, and then the second servo motor is started. When one of the longitudinal baffles 22 contacts the steel ball, it will gently push the steel ball until both longitudinal baffles 22 contact the steel ball, and the steel ball is clamped. Then, the lifting platform 2 is rotated to lift the testing platform 9 as a whole, so that the steel ball and the pressure head 3 are first lightly contacted, and then the pressure handle on the Rockwell hardness tester 1 is rotated, and the pressure head 3 is used to perform a load test. After the test is completed, the pressure handle is reversed to release the pressure. At this time, the reading on the pointer plate 4 is the hardness value of the steel ball. After the test is completed, if the hardness value reaches the qualified standard, the tilt direction of the guide plate 52 can be adjusted first. During the adjustment, the fourth servo motor is directly started, and its output shaft drives the movable rod 51 to rotate, and then the guide plate 52 can be rotated together. After the guide plate 52 rotates from the middle to one side, the output shaft of the second cylinder 24 can be started to extend, so that the first concave frame 8 makes a circular axis motion with the rotation axis between the adapter seat 6 and the hinge seat 7, and finally the test table 9 is tilted. Subsequently, the first servo motor is started in the reverse direction, and the first transverse slide plate 12 and the second transverse slide plate 15 move away from each other. The first transverse baffle 14 and the second transverse baffle 17 are separated from the steel ball until the first transverse baffle 14 returns to its original position, and then the output shaft of the first cylinder 13 is started to retract, and the first transverse baffle 14 is brought downward and passes through the through slot 10, and finally the first transverse baffle 14 is sunken below the detection table 9, and then the second servo motor is started in the reverse direction to separate the two longitudinal baffles 22 from the steel ball, and the steel ball falls along the inclined direction of the detection table 9, and first falls into the guide groove 48, and then falls into the discharge box 49, and finally falls into the corresponding loading box under the guidance of the guide plate 52; If the hardness value after the test does not meet the standard, the fourth servo motor is started in the reverse direction to rotate the guide plate 52 to the other side and discharge it into another loading box; During the above-mentioned discharging process, the corresponding third servo motor is started at the same time, so that the corresponding sealing plate 32 seals the bottom of the storage hopper 29 again, and then the output shaft of the corresponding third cylinder 33 is started to retract, so that the steel balls inside the storage hopper 29 fall down and fill again, and then the output shaft of the third cylinder 33 is started to extend, so that the lowest steel ball is isolated from the upper steel ball, and the detection work of the next steel ball can be continued in the same way as above.

[0027] Compared with the related art, the casting steel ball hardness detection device provided by the present invention has the following beneficial effects: ①. The steel ball can be quickly clamped and fixed by the first transverse baffle 14, the second transverse baffle 17 and the two longitudinal baffles 22, and the fixed position can be in the center of the test table 9 to ensure the accuracy of the test results; ②, by using the threaded cooperation of the first bidirectional lead screw 11 and the second bidirectional lead screw 19, the spacing between the first transverse baffle 14 and the second transverse baffle 17, and the spacing between the two longitudinal baffles 22 can be clamped and used according to the diameters of different steel balls, and the four storage hoppers 29 with different inner diameters can be filled with steel balls of different diameters, so that they can be adaptively adjusted for steel balls of different diameters, and the application range is wide; ③. During the entire testing process, the steel ball can automatically fall onto the testing table 9 through mechanical operation, and can be positioned and clamped at the same time. Moreover, the guide of the guide plate 52 can be adjusted according to whether the hardness value of the steel ball after testing is qualified, thereby realizing automatic material picking. The entire testing process is relatively coherent and has a high degree of automation. There is no need for manual picking and placing in sequence, which reduces the energy expenditure of the staff.
