The technical solutions of the present invention will be further described in detail below through specific embodiments in conjunction with the drawings.
 Such as Figure 1 to Figure 2 As shown, a steel ball detection and screening device includes a box body and a feeding mechanism. The feeding mechanism includes a feeding bin 1 fixed on the box body. The outlet of the feeding bin 1 is fixed on the box body. The upper end of the fixed disc ring 2 is provided with an upper through hole 21 that matches the outlet of the feed bin, and the fixed disc ring 2 is also provided with a lower through hole 22. The fixed disc ring 2 The inner sleeve is provided with a rotating disk 3 driven by a motor. The outer arc surface of the rotating disk 3 is provided with at least one hole 31. The hole 31 can only accommodate one steel ball 9, and the center of the hole 31 is The centers of the upper through hole 21 and the lower through hole 22 are on the same plane, the lower through hole 22 is fixedly connected to the feed end 41 of the feed pipe 4, and the discharge end 42 of the feed pipe is fixedly provided with a guide member 6, One end of the guide member 6 is fixedly connected with the piston rod of the cylinder 5 fixed on the box body, and the cylinder 5 is connected with the solenoid valve;
 The detection mechanism includes a stepping motor, a conveyor belt 7 located at the lower end of the feeding tube driven by the stepping motor, and at least one clamping portion 8 is fixed on the conveyor belt 7, and the clamping portion 8 includes a fixed on the conveyor belt 7 on the fixing seat 84, the fixing seat 84 is fixedly provided with at least one pressure sensor 83, the pressure sensor 83 is provided with a support positioning portion 81 movably connected with the fixed seat 81, the support positioning portion 81 is in the middle The through hole 82 also includes a flaw detector probe 11 fixed above the middle of the conveyor belt 7, and a pneumatic measuring instrument detection part 10 fixed on the box is provided directly above the end of the conveyor belt 7, and it also includes a detection unit 10 located below the end of the conveyor belt 7. 的Classification receiving device 13.
 Specifically, the steel ball 9 enters the clamping part 8 on the conveyor belt 7 through the feeding mechanism individually and intermittently, and is driven by the conveyor belt 7. When the steel ball 9 moves to the upper part of the supporting part 12 and the bottom of the flaw detector probe 11, the function of the stepping motor The pressure sensor 82 and the flaw detector 11 will feed back the quality data of the steel ball 9 and the internal condition data of the steel ball measured by the flaw detector 11 to the PLC. When the clamping part 8 moves on the conveyor belt 7 When reaching the detection part 10 of the pneumatic measuring instrument, the pneumatic measuring instrument 10 will transmit the measured diameter data of the steel ball 9 to the PLC. Under the action of the PLC, the measured data will be integrated and analyzed, and the steel ball 9 will be screened and classified as required .
 Among them, the through hole 82 is a circle, a regular triangle or a regular quadrilateral. In this embodiment, a circle is used. The circle is not only convenient for processing, but also has a larger and more stable contact surface with the steel ball, and can also ensure that the center of gravity of the steel ball coincides with the center of the through hole. At the same time, the pressure sensors 83 are distributed at the top corners of the regular quadrilateral, and the data measured by the pressure sensors 83 are more accurate under the simultaneous action of the two structures.
 Among them, the flaw detector is an ultrasonic flaw detector. The ultrasonic flaw detector has strong penetrating ability. It can detect the internal structure of the steel ball. It can select out the unqualified products such as cracks, looseness and pores that cannot be distinguished by the naked eye. Quality, ultrasonic flaw detector will not cause harm to human body.
 Among them, the cylinder 5 is connected with the solenoid valve. Under the control of the PLC, the solenoid valve controls the cylinder 5 to move the piston rod, and the guide 6 moves downwards synchronously. At this time, the feed pipe 4 moves downwards and the steel ball The movement from the discharge end 42 of the feed pipe 4 to the clamping part 8 on the conveyor belt 7 is more precise and stable.
 Wherein, the lower through hole 22 of the fixed ring disk 2 is located at the lowest position opposite to the upper through hole 21, and can be conveniently connected with the feed pipe 4 at this time.
 Among them, the probe 101 of the pneumatic measuring instrument is a standard customized probe, so the dimensional accuracy is high when the pneumatic measuring instrument is used for measurement. The probe 101 and the trachea 103 are connected by a fastener 102, which is convenient and quick to replace. Environmental factors have little influence, and it is convenient to use for steel ball size detection of different sizes and different environments.
 Among them, the sorting and receiving device is a number of Y-shaped grooves connected in series. At the bifurcation, a baffle controlled by a cylinder is provided to change the motion trajectory of the steel ball, and the solenoid valve controlled by the PLC determines the movement of the cylinder piston rod. The steel balls are classified according to the required parameter characteristics.
 The above-mentioned embodiments are only preferred solutions of the present invention, and do not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
