However, to ensure that during the range error of above-mentioned requirements, the both ends for distribution of being popped one's head in swivel head devise clamping dress
Put, it is fixed because whole pivot is driven by main shaft for ensureing that bar reaches the pivot popped one's head in swivel head with one heart
The servicing unit both ends installation that position guide pin bushing is hung on the bearing block that fixed main shaft rotates, in this case, each position
Connection installation, cumulative errors caused by positioning the making precision of guide pin bushing be all extremely difficult to position guide pin bushing static center with probe revolve
Turn the requirement of center concentricity.Simultaneously in order to ensure that a large amount of bars can pass through 4 guide pin bushings in swivel head, typically make
Gap reaches 0.1-0.4mm, then because some heavier bars all can be automatically in guide pin bushing bottom surface of sending an invitation card in guide pin bushing internal clearance
Phenomenon, so make concentricity between bar and probe pivot bigger, due to the influence of concentricity, detection
When bar enter in one direction fashionable, Detection results are fine, but rotating 90 ° or 180 ° entrance of bar can not just detect
Defect or echo is greatly lowered the defects of detect, becomes defective work from certified products.If by detection sensitivity by worst
Direction be defined set sensitivity, can will be determined as defective work in the bar of certified products mass range again, cause product because
Detection error and caused significant wastage, are referred to as that circumferential sensitivity error is exceeded, and the reaction of this index is super in technical indicator
On sound wave 2dB has been brought up to by standard in nuclear power, aviation and war products not allow more than 4dB.
