    摘要: A clamping and positioning device includes a base, a rotary member, a moving assembly and an elastic member. The rotary member is rotatably disposed on the base and includes a stopping surface facing the base. The moving assembly includes a moving member movably disposed on the base to have a first and a second position. When being at the first position, the moving member is pressed against the rotary member to allow the stopping surface to apply a normal force to the base; when being at the second position, a gap is formed between the moving member and the rotary member so the normal force applied by the stopping surface of the rotary member is released from the base. The elastic member has two ends connected to the base and the moving member, respectively. The elastic member normally causes the moving member to be at the first position.

    摘要: A hydrostatic rail guide includes a guide rail, a guide carriage, a hydrostatic supply device, a measurement device and a controller. The guide carriage is hydrostatically mounted on the guide rail and has a hydrostatic channel filled with oil. The oil keeps the guide carriage and the guide rail at a gap. The hydrostatic supply device is adapted for supplying the oil to the hydrostatic channel and adjusting the pressure of the oil. The measurement device is installed on the guide carriage and adapted for detecting the gap between the guide carriage and the guide rail and for producing a distance signal of the measured gap. The controller is connected to the hydrostatic supply device and the measurement device. The controller is adapted for controlling the hydrostatic supply device, based on the distance signal, in order to adjust the hydrostatic pressure of the oil after being pressurized.
