The invention discloses a gear-rack type laser scanning ball-sorting device. An input rack is arranged in a sliding chute at two ends of the input rack; one end of the input rack is provided with a pressure sensor; a positioning block is arranged outside the pressure sensor; the other end of the input rack is in contact with a driving rack device; the toothed part of the input rack is meshed with a pinion of a first duplex gear; a gearwheel of the first duplex gear meshes with the pinion of a second duplex gear; the gearwheel of the second duplex gear meshes with an output rack; two ends of the output rack are arranged in the other sliding chute; a laser is arranged below the output rack; a fixing plate is arranged above the laser on the same side; and a photoelectric detector is flat laid on the lower surface of the fixing plate. As the device adopts gear transmission and a geometrically similar triangular amplification principle to amplify the difference between a measured ball and a datum ball, the device has the advantages of high measurement precision, sorting accuracy, simple operation and automation easiness, and is particularly applicable to sorting batches of balls small in diameter.
Description
technical field [0001] The invention relates to a sorting device, in particular to a rack-and-pinion laser scanning sorting device for balls. Background technique [0002] Studies have shown that if the diameter difference of the balls in the rolling bearing exceeds a certain limit, it will cause unstable operation of the bearing, seriously affect the stress distribution of the internal balls, lead to early failure of the bearing, and shorten the fatigue life of the rolling bearing. Therefore, each rolling bearing production unit requires the balls to be sorted according to their diameter. [0003] However, at present, the sorting of balls still adopts the method of manual measurement one by one, and the instruments used are still traditional mechanical measuring devices, whose measurement accuracy can no longer meet the requirements of precision components, resulting in poor measurement accuracy and low sorting efficiency. It affects the quality and production efficiency o...
