Main contents of mechanical installation accuracy of carton

The installation level refers to the parallelism of the measured elements to the horizontal plane and is a special case of parallelism. Such as the installation level of the equipment base board, the installation level of the work platform, and the installation level of the machine guide surface

Parallelism is the degree to which a measured feature is parallel to a reference feature. It is divided into parallelism between plane and plane, such as the parallelism between different guide rail faces of the machine bed; the parallelism between plane and straight line (axis), such as the parallelism between the centerline of the machine tool spindle and the rail surface of the bed; axis and axis Parallelism, such as the parallelism between the drive shafts.

Verticality is the degree to which the measured feature is perpendicular to the datum element. It is divided into the verticality of the plane and the plane, such as the verticality of the pillar guide surface of the planer, the vertical lathe, the boring machine and the rail surface of the bed; the perpendicularity of the straight line (axis) and the plane, such as the spindle axis of the radial drilling machine The perpendicularity to the work surface of the base; the perpendicularity of the straight line (axis) and the straight line (axis), such as the perpendicularity of the center line of the piston compressor cylinder and the center line of the crankshaft.

Plumbness is the degree to which the measured element is perpendicular to the geoid. It is a special case of verticality. For example, the verticality of the hydraulic press column, the column guide of the machine tool, the tower equipment, etc. and the geoid.

Coaxiality refers to the extent to which the axis being measured is coaxial with respect to the reference line. It is divided into the coaxiality between the hole and the hole, such as the coaxiality between the cylinder and the slide of the piston compressor; the coaxiality between the shaft and the hole, such as the rotor and stator of the generator, the rotor and the cylinder of the turbine Coaxiality between the shaft; the coaxiality between the shaft and the shaft, such as the coaxiality between the drive shaft and the driven shaft (coupling coupling).
