摘要： PURPOSE:To measure the inclination angle of a surface to be measured by projecting planar light on one plane to be measured, and picking up the image of a light-ray pattern caused by the planar light with a CCD sensor and the like on planar coordinates. CONSTITUTION:The crossed axes angle of a work W having two planes 1 and 2 as planes to be measured is measured. At this time, an intersection line 3 between the two planes 1 and 2 is made to agree with the X axis. A CCD camera 4 as a vision sensor is provided on the Z axis which is orthogonally intersected with the X axis. The image is picked up with the camera 4 toward an intersection O of both axes X and Z in a field of view 5. The YZ plane is inclined by an angle beta, and this plane is made to be the plane to be illuminated with planar light. The planar light 7 passing an original point O is projected on this plane. The planar light 7 which is emitted from an light emitting device 8 hits the planes to be measured a 1 and 2, and linear light-ray patterns 9 and 10 passing the original point O are formed on both planes. At this time the crossed axes angle between the two planes 1 and 2 can be expressed as the sum of the inclination angles alpha1 and alpha2 of the planes 1 and 2 with respect to the Z axis.

摘要： PURPOSE:To control so that a detected angle goes to a set angle and to decrease the manhour for working by providing a distance sensor for detecting a bending angle of a work on one of the upper metallic die and the lower metallic die and providing an interface for feeding the output of the distance sensor to an NC device. CONSTITUTION:On the upper face side of the lower metallic die 9, a V-groove 36 is formed, and in its slant face, an eddy current sensor 37 is buried. The eddy current sensor 37 generates an AC magnetic field, detects a distance L extending from the end face to a work 5, and supplies it to an A/D converting part 38. The A/D converting part 38 brings a detected value to A/D conversion and supplies it to an angle calculating part 40. The angle calculating part 40 calculates an angle theta of the work 5, and supplies it to a display part 41 and an interface 42. The interface sets the supplied angle theta as the present angle of the work 5, when it is supplied to an NC controller 2 as the bending angle theta, and controls a moving amount of a driving mechanism 14 so that the angle thetaof the work 5 goes to a set angle.

摘要： PURPOSE:To measure a tilt of work by arranging a main distance sensor near the work to be machined and more than one sub-distance sensors near the main distance sensor. CONSTITUTION:An eddy current sensor 37 and optical fiber sensors 38a and 38b are buried into a slant face of a V groove 36 of a bottom die 9. When an AC drive signal is supplied, the sensor 37 generates an AC magnetic field to detect a distance L0 from an end face thereof to work 5 and the results of detection are supplied to a judgement section 39. Optical fiber sensors 38a and 38b are arranged above and below the sensor 37 and when a laser light is supplied from a fiber driving circuit 40, it is emitted from the end face to irradiate the work 5. The laser light reflected on the work 5 is picked up to be introduced to the circuit 40. The judgement section 39 measures an angle of the work 5 from the results of detection of the sensors 38a, 38b and 37.

摘要： PURPOSE:To measure the distance between a nozzle and a work right under the nozzle with good accuracy by constituting the nozzle of a heat-resistant non-metallic material, coating a thin metallic film on the inside surface thereof and providing an eddy current type displacement sensor which detects the distance between the nozzle and the work to the top end thereof. CONSTITUTION:The nozzle 19 is formed of the heat-resistant non-metallic material such as ceramics and is highly resistant to heat. The thin metallic film 21 is coated on the inside surface of such nozzle 19 to reflect a laser beam LB and to prevent the nozzle 19 from injury. A coil 25 as the eddy current type displacement sensor is provided in proximity to the top end of the nozzle 19. The metallic film 21 coated on the inside surface of the nozzle 19 is extremely thin and is apart from the sensor 25; therefore, the greater part of the eddy current flows to the work W side when the sensor 25 is energized by a high frequency. The eddy current flowing in the film 21 is small and is negligible. Thus the sensor 25 can measure the distance L between the nozzle 19 and the work W right under the nozzle with the high accuracy.
