Description

Technical Field

[0001] This utility model relates to the field of object sorting technology, and in particular to a steel ball hardness sorting device. Background Technology

[0002] In the fields of machinery manufacturing and quality inspection, steel balls, as important basic components, are widely used in various mechanical equipment. Their hardness is one of the key factors determining their performance and service life. Accurate and efficient testing and sorting of steel ball hardness is crucial for ensuring product quality, improving production efficiency, and reducing costs. With the continuous development of industrial technology, the requirements for the accuracy, speed, and automation of steel ball hardness testing and sorting are also increasing.

[0003] In current technologies, mechanical methods are commonly used to test the hardness of steel balls. A common practice is to sample a certain proportion of steel balls and mark three hardness values ​​on them, such as using Rockwell or Vickers hardness testing methods. These methods rely on specialized hardness testing equipment, require significant manual intervention, and follow specific testing procedures. In addition, some companies combine traditional mechanical structures and simple electrical controls for steel ball feeding and initial screening, but still primarily rely on the aforementioned sampling methods for hardness testing. Some manufacturers also use basic physical property testing methods to assist in judging steel ball quality, but there is still no effective and comprehensive solution for accurate hardness testing.

[0004] However, these existing technologies have significant drawbacks. Traditional sampling inspection methods require destroying the steel balls, which not only wastes materials but also makes it impossible to inspect every single steel ball, failing to achieve 100% measurement. This can lead to steel balls that do not meet the hardness requirements flowing into subsequent production stages, affecting the overall quality and performance of the product. Utility Model Content

[0005] This application provides a steel ball hardness sorting device, which facilitates efficient testing without damaging the steel ball.

[0006] This application provides a steel ball hardness sorting device, which adopts the following technical solution:

[0007] A steel ball hardness sorting device includes a frame, a hopper at the top of the frame, a first lever inside the hopper, a fixing plate at the top of the first lever, a first drive assembly at the bottom of the fixing plate, a drop trough at the bottom of the hopper, a sorting trough at the bottom of the drop trough, a second drive assembly on one side of the sorting trough for driving the sorting trough to rotate, an inclined track on one side of the sorting trough, a hardness sensor on the track, a sorting assembly at the end of the track, and OK and NG discs on one side of the sorting assembly.

[0008] By adopting the above technical solution, the steel ball hardness sorting device designed in this utility model can sort steel balls by hardness during use. The hopper can store steel balls. The first drive component drives the first lever to rotate to control the steel balls to fall into the drop trough. The second drive component drives the sorting trough to rotate so that the steel balls are arranged at equal intervals. The hardness sensor can detect the hardness of the steel balls. The sorting component can sort qualified steel balls into the OK tray and unqualified steel balls into the NG tray, thus completing the automated and non-destructive sorting of steel ball hardness.

The effect of the second drive motor controlling the rotation of the sorting tank by driving the second transmission gear set is to drive the sorting tank to rotate, so that the steel balls can be arranged at equal intervals and pass through the hardness detection sensor, which facilitates the subsequent detection and sorting of the hardness of the steel balls.

[0017] Preferably, the hardness sensor is fixed to the track, and multiple hardness sensors are provided, which are evenly distributed.

[0018] By adopting the above technical solution, multiple hardness sensors are fixed to the track and evenly distributed during use. This allows the steel ball to be subjected to more comprehensive and accurate hardness detection by multiple hardness sensors as it passes through the track, improving the accuracy and reliability of steel ball hardness detection and thus ensuring the precision of steel ball hardness sorting.

A second lever is disposed in the groove. A third drive motor is disposed at the bottom of the second lever. The third drive motor performs sorting by driving the second lever to block the grooves in different directions.

[0020] By adopting the above technical solution, during use, at the end of the track, the third drive motor drives the second lever in the sorting block groove to block the grooves in different directions, which can sort qualified and unqualified steel balls. The steel balls are then smoothly entered into the OK and NG disks through the inclined channel, realizing the automated and non-destructive operation of steel ball hardness sorting.

[0021] Preferably, an inclined channel is provided between the sorting component and the OK and NG disks, so that the steel balls can smoothly enter the OK and NG disks.

The first drive motor 51 can be a stepper motor, which can precisely control the rotation angle and speed of the first lever 3. A first transmission gear set 52 is connected to the top of the first drive motor 51. The first transmission gear set 52 can be a cylindrical gear transmission, which transmits the power of the first drive motor 51 to the first lever 3. The first transmission gear set 52 is connected to the top of the first lever 3, and drives the first lever 3 to rotate through the first drive motor 51. A through hole 16 is provided in the hopper 2, which allows the steel ball to pass through.

The OK tray 12 is used to store qualified steel balls, and the NG tray 13 is used to store unqualified steel balls.

[0038] Working Principle: This steel ball hardness sorting device integrates storage, conveying, detection, and sorting functions. A first drive assembly controls a first lever, causing steel balls to fall orderly from the hopper into the drop trough, and then into the sorting trough. A second drive assembly drives the sorting trough to rotate, conveying the steel balls to a track. Multiple hardness sensors on the track detect the hardness of the steel balls, and the results are fed back to the sorting assembly. Based on the detection results, the sorting assembly, via a third drive motor, drives a second lever to block grooves in different directions, conveying qualified and unqualified steel balls to the OK and NG trays respectively. The entire process achieves non-destructive automated sorting of steel balls by hardness, avoiding the problems of damage to steel balls and inability to perform 100% inspection found in traditional sampling inspections, thus improving production efficiency and product quality.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
