Abstract
The invention provides a method and device for measuring the assembly size of an internal hole of a hydraulic torque converter. A measuring bar is placed in the internal hole of the hydraulic torque converter, and a pressing shaft is arranged parallel to the head portion of a displacement sensor. The pressing shaft is moved to the position over the measuring bar, and a certain pressure is exerted on the pressing shaft to enable the measuring bar to be pressed tightly in the hydraulic torque converter. When a pressure sensor detects that the pressure reaches an index value, measuring software is started up to carry out measurement. The length of the measuring bar minus a measuring value of the displacement sensor is the depth size of the internal hole of the hydraulic torque converter, the measuring data are stored and finally the pressing shaft is raised again to separate from the measuring bar. According to the method and device on the basis of the positional relations between the measuring bar and the displacement sensor, an indirect method is adopted to measure the assembly size of the internal hole after the internal assembly errors of the hydraulic torque converter are reduced, and therefore the method and device improve the measuring accuracy of the assembly size of the internal hole of the hydraulic torque converter.
