A detection head 27 is installed at one end of the moving plate 25 close to the clamping mechanism 3.

[0024] The interior of the vertical pole 21 is hollow and a screw rod 22 is movably installed thereon. The top end of the screw rod 22 is fixedly connected to a first motor 23. The lifting platform 24 is threadedly connected to the screw rod 22. A slide groove 211 is provided at the front end of the vertical pole 21. The lifting platform 24 and the slide groove 211 form a sliding connection. A turning knob 241 is movably installed on the surface of the lifting platform 24. The turning knob 241 is fixedly connected to the first gear 26 through a rotating shaft.

[0025] Specifically, start the first motor 23, and the first motor 23 drives the screw rod 22 to rotate. Since the lifting platform 24 is threadedly connected to the screw rod 22, under the limit of the slide groove 211, the lifting platform 24 can move up and down and drive the detection head 27 to move up and down, so as to adjust the height of the detection head 27, so that the detection head 27 can face the center of the steel ball. After the adjustment is completed, turn the knob 241, and the knob 241 drives the first gear 26 fixedly connected thereto to rotate, and the first gear 26 drives the rack 251 meshing therewith to move left and right, and the rack 251 drives the movable plate 25 fixed thereto to move left and right, so that the detection head 27 can move left and right until the detection end of the detection head 27 fits the surface of the steel ball, and the adjustment of the position of the detection head 27 is completed.

[0026] To solve the technical problem of how the steel ball rotates, please refer to Figure 4 , this embodiment provides the following technical solutions:

[0031] Specifically, the second motor 34 is started, and the second motor 34 drives the second gear 33 to rotate. The second gear 33 then drives the turntable 32 engaged therewith to rotate. The turntable 32 then drives the placement plate 35 at its upper end to rotate until the steel balls of different specifications rotate to the vicinity of the detection head 27.

[0032] Working principle: When using the steel ball surface defect detector, first place steel balls of different specifications into the matching placement slots 351, start the first motor 23, the first motor 23 drives the screw rod 22 to rotate, and the lifting platform 24 moves up and down to adjust the height of the detection head 27. After the adjustment is completed, turn the knob 241, the knob 241 drives the first gear 26 to rotate through the rotating shaft, and the first gear 26 drives the moving plate 25 to move left and right through the rack 251, so that the detection head 27 moves left and right until the detection end of the detection head 27 is in contact with the surface of the steel ball. The third motor 37 is started again at this time, and the third motor 37 drives the third gear 38 to rotate, and the third gear 38 drives the placement plate 35 meshing with it to rotate, so that the steel ball can rotate while being detected, thereby improving the comprehensiveness of the detection. When a steel ball is detected, the second motor 34 is started again, and the second motor 34 drives the second gear 33 to rotate, and the second gear 33 drives the turntable 32 meshing with it to rotate, until the next steel ball rotates to the vicinity of the detection head 27, and then the position of the detection head 27 is readjusted to facilitate the detection of the new steel ball.
