The Fast Measurement for the Relative Position of Flange-End Holes

Abstract: For the flange end of the internal combustion engine crankshaft, the position of threaded holes and pinhole relative to the journal reference plane affects the dynamic balance and thermal efficiency of the engine, and therefore, this parameter measurement has a positive significance in the crankshaft manufacture. This paper proposes a system for quickly measuring the relative position of the flange-end holes, which uses a pneumatic linear variable differential transformer to form measuring benches for getting … Show more

“…For sheet metal parts, this need is even more prominent because the feature holes on a surface serve as references for the installation and positioning of other parts. Traditionally, as the most common feature in the industry [4][5][6], measurements of circular holes are usually performed by skilled workers using a gauge or a caliper, or by a coordinate measuring machine (CMM) with high precision. However, this inevitably leads to problems that include high labor intensity, low efficiency, and high costs.…”

“…Huang et al used the laser displacement sensors to detect the profile lines and achieve the measurement of flanges in trains [19]. Wang et al proposed a fast measurement method for flange-end holes using multi-camera to locate the flange-end holes with a position accuracy of 0.1mm [20]. The position of deep-sea pipeline is also obtained with high accuracy by localizing the center of flange [21].…”

“…Since the distribution of unbalanced inertial forces on the X and Y plane has changed, the traditional dynamic balance measurement method is not applicable. Until now, most of the solutions to this problem have used traditional dynamic balancing machines with ro- tary fixtures [18]- [20], as shown in Fig. 2(b).…”
