With the above embodiments, the utility model discloses a usage principle and working process are as follows: when the tapered roller 400 needs to be placed on the fastening seat 210, the fastening cylinder 230 is lifted by the pedal hydraulic cylinder 120, the fastening cylinder 230 drives the fastening ring 220 to move upwards, after the fastening cylinder 230 is separated from the fastening seat 210, the small end of the tapered roller 400 with the standard size is inserted into the fastening ring 220, then the tapered roller 400 is placed in the groove of the fastening seat 210 downwards, the fastening cylinder 230 is moved downwards to reset, the fastening ring 220 is pressed against the tapered surface of the tapered roller 400, then the sorting frame is moved downwards to the preset position, the positions of the first measuring rod 311 and the second measuring rod 321 are adjusted, the first measuring rod 311 and the second measuring rod 321 are both abutted against the preset section of the tapered roller 400, the positions of the contact of the first lever micrometer 315 and the contact of the second lever micrometer 325 are adjusted, the contact of the first lever micrometer 315 and the preset section of the tapered roller 400 are adjusted, the contact of the second lever 325 and the preset section of the tapered roller 315 are abutted, the second lever 325 is deflected, and the diameter of the tapered roller 325 is just zero when the pointer is rotated in the dial 325, and the diameter of the second lever 325 is not adjusted, and the error of the dial 325 is not adjusted, and the diameter of the standard lever 325; when the diameter of the measured tapered roller 400 is smaller than the standard diameter, the pointers of the first micrometer 315 and the second micrometer 325 do not rotate; when the measured diameter of the tapered roller 400 is larger than the standard diameter size, the pointers of the first micrometer 315 and the second micrometer 325 are rotated.
When the motor 242 drives the fastening seat 210 to rotate, the fastening seat 210 drives the synchronizing ring 251 to synchronously rotate clockwise through the synchronizing rod 260, on one hand, the synchronizing ring 251 drives the fastening ring 220 to rotate through the elastic strips 241, on the other hand, the first speed reducing wheel 257 is driven to rotate counterclockwise through friction force, the first speed reducing wheel 257 drives the second speed reducing wheel 259 to rotate in the same direction through the second rotating shaft 258, the second speed reducing wheel 259 drives the first reversing wheel 254 to drive the first rotating shaft 255 to rotate clockwise, the first rotating shaft 255 drives the second reversing wheel 256 to rotate clockwise through ratchet teeth in a one-way mode, the second reversing wheel 256 drives the driving ring 252 to rotate counterclockwise, so that the fastening ring 220 is decelerated, thus, a differential speed exists between the fastening ring 220 and the fastening seat 210, and the elastic strips 241 accumulate force.
After the fastening seat 210 stops rotating after the detection is finished, the elastic strip 241 releases the force to make the fastening ring 220 continue to rotate clockwise for a section in the fastening cylinder 230, and make the fastening ring 220 move down along the fastening cylinder 230 and squeeze the small end of the tapered roller 400, and after the fastening cylinder 230 is lifted, the tapered roller 400 is squeezed out for taking. When the fastening cylinder 230 is lifted up, the tapered roller 400 is extruded and taken out, and the compressed elastic bar 241 is reset to reset the fastening ring 220 to rotate counterclockwise. When the tapered roller 400 rotates and the diameter of the tapered roller 400 is not uniform, the pointers of the first lever micrometer 315 and the second lever micrometer 325 periodically fluctuate, so that the unqualified tapered roller 400 is screened out.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
