A roundness measuring apparatus includes a stylus stocker and a controller. The stylus stocker stores plural types of styli prepared corresponding to shapes of measurement sites of a measurement target object. The stylus stocker can store styli in such a manner that each stylus can be held thereon and taken out thereof. The stylus stocker is provided outside a measurement region, which is determined on the basis of the operation range of a turntable and a detector driving mechanism. The detector driving mechanism can move the detector to the outside of the measurement region. When a measurement command is given, the controller carries out roundness measurement of the object while controlling the turntable and the detector driving mechanism. When a stylus replacement command is given, the controller carries out stylus replacement operation between a detector main unit and the stylus stocker while controlling the detector driving mechanism.

In a surface shape measurement device that measures the surface shape of a sample (W1, W2) by moving a probe (16, 26) in a sliding fashion along the surface of the sample (W1, W2) and thereby detecting the amount of displacement of the probe (16, 26) caused by irregularities on the surface, an initial amount of displacement is detected which is the amount of displacement of the probe (16, 26) when the probe is first placed in contact with a measurement start point on the surface of the sample (W1, W2), and the amount of displacement of the probe (16, 26), detected as it is moved in a sliding fashion along the surface, is compared with the initial amount of displacement to determine whether the probe (16, 26) has reached a measurement end point.

The invention discloses an onboard measuring working cabin which can improve operation environment, improves seacoast measuring efficiency and quality, and is convenient to carry and assemble. The onboard measuring working cabin comprises four support pillars, four cross beams and three stock frames, wherein the four cross beams are respectively connected with the upper ends of the adjacent support pillars horizontally through clamping locks, the three stock frames are respectively connected with the lower ends of the adjacent support pillars horizontally through clamping locks, the upper ends of the four support pillars are all provided with first connecting pieces. The onboard measuring working cabin further comprises second connecting pieces matched with the first connecting pieces. Steel wire ropes are connected with the second connecting pieces. The other ends of the steel wire ropes are connected with clamping sleeves with groove-shaped sections and downwards groove openings. Two side faces of each clamping sleeves are provided with top threads. The onboard measuring working cabin further comprises upper blocking plate capable of being connected between the four cross beams, side blocking curtains capable of being connected between the cross beams and the stock frames, and table panels capable of being placed on the stock frames.

The invention relates to a shafting hot alignment device and a shafting hot alignment method. Horizontal and vertical eddy current sensors are disposed at shafting bearing positions or alignment required positions of a unit around a journal. The horizontal and vertical eddy current sensors are used to measure shafting lateral clearance and vertical clearance respectively. Reflecting paper is adhered to a shaft at the alignment required position, and a revolution speed sensor corresponds to the reflecting paper is used for keyway-phase angle marking. Lateral clearance and vertical clearance value signals of the shafting of the eddy current sensor acquisition unit are processed by an alternating current blocking circuit and a signal attenuation circuit and are then transmitted into an ADC (analog to digital converter) and converted into digital signals, and the digital signals are transmitted to a rear-end ARM (advanced RISC machines) master control chip. When the shafting of the revolution speed sensor acquisition unit rotates to the reflecting paper, a signal of instant phase marking angle value is output, a square signal is output to the ARM master control chip, the signals are subjected to difference calculation by the ARM master control chip through hot alignment software, and data signal of shafting position compensation value required by hot alignment is output to a data output device.
