Detection of position error of drilling pump housing

The SL3NB-1300 drilling pump produced by our factory is one of the main supporting equipments of the oil drilling rig. The φ460mm hole and the φ600mm hole of the drilling pump casing (see Figure 1) are equipped with two transmission gear shafts respectively, and the φ525mm hole is equipped with reciprocating pistons. . The following positional accuracy requirements are proposed on the design drawings: in order to ensure smooth gear transmission and high contact accuracy of the tooth surface, the φ460mm hole axis is defined as φ600mm hole axis.
