[0030] The present invention provides a steel ball diameter measuring device, the working principle of which is as follows: during operation, the feed seat 301 can be docked with the external conveying structure, and when the conveying structure conveys the steel balls to the feed seat 301, due to the inclination of the feed seat 301, a plurality of steel balls will automatically roll down to a position close to the feeding roller 602, and when the steel balls roll from the feed seat 301 to contact the feeding roller 602, the first driving motor 603 can cooperate with the first pulley 605, the second pulley 606 and the transmission belt 607 to drive the feeding roller 602 to rotate until one of the feeding slots 604 on the feeding roller 602 docks with the steel balls, so that the steel balls can naturally roll down into the feeding slot 604 under the action of gravity, and the feeding roller 602 can continue to rotate. When the rotation continues, the steel ball at the rear can dock with other feeding troughs 604, and the steel ball already in the feeding trough 604 will move close to the two discharging cylinders 401 as the feeding roller 602 rotates, and after reaching a certain rotation angle, the steel ball will naturally roll onto the two discharging cylinders 401 for subsequent measurement and discharging processing. When the steel ball rolls onto the two discharging cylinders 401 through the feeding roller 602 and continues to roll, the outer surface of the steel ball, especially the two sides of the steel ball, can be cleaned by the brush part 405 provided between the two limit baffles 404 to avoid a large amount of impurities and debris adhering to the two sides of the steel ball and affecting the subsequent measurement accuracy of the steel ball diameter. In this process, two exhaust fans 11 can be used to clean the steel ball. 02, in conjunction with the dust hood 1105, the air inlet duct 1104 and the air outlet duct 1103, a large amount of debris and dust that is scattered due to cleaning is pumped into the dust box 1101 for centralized collection, which is convenient for subsequent centralized processing. When the first drive motor 603 is working, it can drive the rotating shaft of the feeding roller 602 to rotate, and the rotation of the rotating shaft of the feeding roller 602 can simultaneously drive the two turntables 701 to rotate, and the rotation of the two turntables 701 can drive the two groups of pressure rods 705 to rotate. When the two groups of pressure rods 705 continue to rotate, they can intermittently produce pressure on the lifting seat 703, and cooperate with the extension and contraction of the spring sheet 704 and the guidance of the second guide rod 706 to drive the lifting seat 703 to form a reciprocating lifting motion up and down, and the steel in the feeding trough 604 When the ball rolls onto the discharge cylinder 401, the lifting seat 703 is in an ascending state, so that when the steel ball rolls on the two discharge cylinders 401, it can be blocked by the limit block 802, so that it stays on the two discharge cylinders 401, to prevent it from rolling into the receiving box 12 before being measured. When the steel ball is blocked and stays on the two discharge cylinders 401, the second drive motor 903 can be started to drive the screw rod 902 to rotate, and the rotation of the screw rod 902 drives the two sliders 907 to move synchronously, thereby synchronously driving the two clamping plates 904 to approach each other, until the two clamping plates 904 are respectively in contact with the two sides of the steel ball. At this time, the infrared ranging sensor 1002 can be controlled to work by controlling the display terminal 1001.When the infrared distance sensor 1002 is working, it can cooperate with the reflector 1003 to measure the distance between the inner sides of the two clamps 904, thereby measuring the diameter of the steel ball. There is no need to manually use a measuring tool to measure. After the measurement is completed, the clamp 904 is reset first, and then the feeding roller 602 is controlled to continue to rotate. The feeding roller 602 continues to rotate, which will drive the lifting seat 703 to descend. The descent of the lifting seat 703 will drive the limit block 802 to descend, thereby releasing the obstruction of the steel ball, so that the steel ball can automatically roll into the receiving box 12 for material collection and processing, and the new steel ball will enter the feeding trough 604 of the feeding roller 602, and the steel ball already in the feeding trough 604 will roll again onto the two discharge cylinders 401. At this time, the lifting seat 703 returns to the rising state again, and the limit block 802 is also reset, and the measurement work can be repeated.
