[0023] Embodiment: As shown in Figures 1 to 5 shown, an on-line detection device with a feedback compensation function includes an inclined main material channel 1.

[0024] The material blocking mechanism 4 includes two horizontal shafts 41 distributed up and down. The left ends of the horizontal shafts 41 are respectively inserted into the outer wall on the right side of the detection groove seat 2 and are close to the front side of the detection groove seat 2, and the right ends are inserted and fixed on the right transverse movement slide plate 42. A material blocking cylinder 43 is fixedly connected to the right transverse movement slide plate 42. The piston rod of the material blocking cylinder 43 passes through the right transverse movement slide plate 42 and is fixedly connected to the outer wall on the right side of the detection groove seat 2;

[0025] A size detection mechanism 5 is provided above the positioning frame 31. The detection mechanism 5 includes a lifting plate 51 parallel to the inner bottom surface of the detection slot seat 2. A displacement sensor 52 is fixed to the right side of the lifting plate 51. The front and rear sides of the displacement sensor 52 are respectively fixed with guide column sleeves 53. The lower end of the guide column sleeve 53 passes through the connecting plate 58 to form a retaining ring 531. A T-shaped guide column 54 is inserted into the guide column sleeve 53. The lower end of the guide column 54 passes through the retaining ring 531 and is fixed to the inner bottom surface of the detection slot seat 2. The parallel detection pressure plate 55, the detection probe of the displacement sensor 52 is located directly above the detection pressure plate 55; the guide column 54 is sleeved with a spring 56, and the two ends of the spring 56 are respectively pressed against the detection pressure plate 55 and the retaining ring 531.

[0026] A material removal notch 312 opposite to the detection slot seat 2 is formed on the front side wall of the positioning frame 31, and a material distribution channel 6 connected to the material removal notch 312 is fixed to the front side wall of the positioning frame 31; when the displacement sensor 52 detects that the outer ring size of the bearing ring 8 is qualified, the bearing ring 8 can be returned to the main material channel 1 and flow out through the main material channel 1; and when the outer ring size of the bearing ring 8 is too small or too large, it will flow out of the material distribution channel 6, and at the same time, it will be fed back to the external cylindrical grinder of the bearing ring 8 in time, and the external cylindrical grinder will automatically adjust the grinding feed amount, thereby avoiding the occurrence of batch unqualified products.

[0027] A guide hole 22 opposite to the horizontal axis 41 is formed on the side wall on the right side of the detection slot seat 2. The horizontal axis 41 is inserted into the guide hole 22. The aperture of the guide hole 22 is equal to the diameter of the horizontal axis 41. A bearing ring 8 is inserted into the detection slot seat 2. The outer walls of the upper and lower sides of the front end of the bearing ring 8 respectively abut against the horizontal axis 41. The horizontal axis 41 can prevent the bearing ring 8 from detaching from the detection slot seat 2 and entering the lower part of the main material channel 1.

[0030] The groove width in the main material channel 1 is equal to the groove width of the detection groove seat 2. The inner bottom surface of the detection groove seat 2 and the inner bottom surface of the main material channel 1 are in the same plane. The side walls and bottom surface inside the detection groove seat 2 are respectively flush with the side walls and bottom surface inside the main material channel 1, so that the bearing ring 8 will not collide during the rolling process.

[0031] The stroke of the transverse cylinder 34 is greater than the groove width of the main material channel 1.

[0032] The guide column sleeve 53 is perpendicular to the connecting plate 58 , and the connecting plate 58 is parallel to the detection pressure plate 55 .

[0033] The stroke of the detection cylinder 57 is greater than the distance from the detection probe on the displacement sensor 52 to the outer wall of the upper end of the bearing ring 8. The detection probe on the displacement sensor 52 will move up to determine whether the size is too small, qualified or too large.

[0034] Working principle: This solution is an online detection device with feedback compensation function. It detects the bearing ring 8 based on the detection device on the main material channel 1, and then feeds back to the cylindrical grinder. The cylindrical grinder automatically adjusts the processing volume, thus having a feedback compensation function. The specific detection method is as follows:

[0035] The horizontal shaft 41 on the material blocking mechanism 4 first enters the detection groove seat 2. The bearing ring 8 falling from the main material channel 1 will be blocked by the horizontal shaft 41 and retained in the detection groove seat 2. Then the transverse cylinder 34 drives the detection groove seat 2 to move into the positioning frame 31. The lifting plate 51 on the size detection mechanism 5 moves downward, and the detection pressure plate 55 elastically presses the bearing ring 8. The displacement sensor 52 that detects the continuous fall detects the size.

[0036] When the detected size is too small or too large, the size detection mechanism 5 is reset, and then the horizontal shaft 41 on the material blocking mechanism 4 is withdrawn from the detection groove seat 2, and its bearing ring 8 enters the material distribution channel 6 from the detection groove seat 2; at the same time, the displacement sensor 52 feeds back the detection result to the cylindrical grinder;

[0037] When the detected size is qualified, the size detection mechanism 5 is reset, and then the transverse cylinder 34 is reset, connected to the transverse axis 41 and then pulled out of the detection groove seat 2, and its bearing ring 8 is output from the main material channel 8.

[0038] The embodiments are intended to illustrate the present invention and are not intended to limit the present invention. Any person skilled in the art may modify the embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
