With reference to said structure design, the work step of the present embodiment is as follows：
Step 1, the charging of the present embodiment cone are realized by universal bearing feed mechanism.It, which is mounted on, surveys It measures between platform 1 and vibrating disk, bearing inner race is delivered to the measurement station of measuring table 1 in an orderly manner by the outlet of vibrating disk, It mainly includes the mounting bracket 22 for being fixed on ground.Mounting bracket 22 is obliquely equipped with feeding track 23, and feeding track 23 is opposite One end of measuring table 1 blocks, and offers discharging flaring 231 in one side wall, and another side wall, which is equipped with, tilts block 232, then It is rolled in inner ring along feeding track 23 to after tilting gear, run-off the straight, inner ring is made to be poured onto discharging flaring 231.Feeding track 23 The opposite another side wall for being equipped with discharging flaring 231 offers perforation, and reclaiming plate, the opposite flaring that discharges of reclaiming plate are equipped in perforation 231 opposite side is equipped with discharging cylinder 25, and lever and the reclaiming plate of discharging cylinder 25 are fixed and be flared 231 towards discharging.So, After inner ring is poured onto discharging flaring 231, by the lever pushing reclaiming plate of discharging cylinder 25, by inner ring by discharging flaring 231 Middle ejection extremely measures station one.
Step 2, close to each other in first mechanical arm 321 and second mechanical arm 322, during clamping inner ring 34, first is high-precision Degree contact digital sensor 331 comes into contact with block, and generates the first of digital quantity according to the active force between probe and block Distance measuring signal, first distance measuring signal are transmitted to exterior terminal and are resolved, and read the diameter of 34 bottom round platform of inner ring to be measured.
Step 3, when first mechanical arm 321 and second mechanical arm 322 clamp inner ring 34 and are transferred to measurement station, inner ring 34 top round platform can be with gradually contradicting with the probe of the second high-precision contact digital sensor 332, and the second high-precision contacts Thus formula digital sensor 332 generates the second distance measuring signal.Second distance measuring signal is also transmitted to exterior terminal and carries out digital independent.
Step 4, after inner ring 34 is transferred to and measures station, contact pin type sensor is moved down with the lever for measuring cylinder, Contact pilotage is gradually contradicted in the bottom of 34 raceway groove of inner ring, and contact pin type sensor exports raceway groove measuring signal to exterior terminal and carries out data It reads.
Step 5, first mechanical arm 321 and second mechanical arm 322 are mounted on the sliding rail of the first sliding platform 351, and first Sliding platform 351 is installed on the sliding rail of the second slip, and the second sliding platform 352 is installed on the sliding rail of third sliding platform 353；Together When, the sliding rail of the first sliding platform 351 is parallel with the sliding rail of the second sliding platform 352, the sliding rail of third sliding platform 353 and The sliding rail of one sliding platform 351 is vertical.So, the first mechanical arm 321 of the present embodiment and second mechanical arm 322 can be based on the The sliding rail of one sliding platform 351 is close to each other or separate, and inner ring 34 to be measured is held on measurement station to realize；Inner ring 34 exists After measuring station measurement, first mechanical arm 321 and second is made by the first sliding platform 351 and the second sliding platform 352 Mechanical arm 322 clamps next measurement station on inner ring 34 to measuring table 1；After inner ring 34 is transferred to next measurement station, First mechanical arm 321 and second mechanical arm 322 is made to retract original position by third measuring table 1, wait for next inner ring 34 to be measured.
Step 6, the present embodiment control clamp motor by control device, can make scroll chuck 421 by inner ring It is clamped on the measurement station of the present embodiment；Again by the control to electric rotating machine 423, rotate inner ring.
Step 7, after scroll chuck 421 clamps inner ring, the lever of elevation carrection cylinder 442 stretches out the present embodiment, makes height Degree measures the close measurement station that mounting base 443 slides along sliding rail, is sensed with 443 fixed elevation carrection of elevation carrection mounting base The top of the probe contacts inner ring of device 445, realizes the measurement to inner ring height.
Step 8, after elevation carrection mounting base 443 declines preset height, two clamping pieces of the second pneumatic clamp are mutual Far from pre-determined distance, the inner wall in inner ring is contradicted respectively.Internal diameter measures baffle 453 and the probe of internal diameter measurement sensor 452 supports It touches, internal diameter measurement sensor 452 measures the active force between baffle 453 according to its probe and internal diameter and measures internal diameter size.
Step 9, the present embodiment is when inner ring not yet contacts scroll chuck 421, the lever of cone pulsation measurement mounting bracket 432 Far from measuring table 1, the clamping piece of the first Pneumatic clamping mechanism 437 is made, which not touch, will enter the inner ring for measuring station； After inner ring is clamped by scroll chuck 421, the lever of cone pulsation measurement mounting bracket 432 stretches out, and inner ring is made to be located at the first pneumatic clamps It holds between two clamping pieces of mechanism 437；By driving the first Pneumatic clamping mechanism 437, the cone on its clamping piece is made to beat and is surveyed Amount ball 436 is contacted with the conical side surface of inner ring, while bores the probe of pulsation measurement sensor 434 and cone pulsation measurement baffle 435 contradict.When cone pulsation measurement ball 436 is contacted with the inner ring rotated, if there is the jump of out-of-flatness in the conical side surface of inner ring It is dynamic, then it can cause the shake of two clamping pieces, and then make the probe of cone pulsation measurement sensor 434 and cone pulsation measurement baffle Variation is generated between 435, and then changes the output variation of cone pulsation measurement sensor 434.
