, (54) PHOTOELECTRIC DEVICE FOR CONTROLLING THE COLLECTION OF OBJECTS

The invention relates to a measurement technique and can be used for controlling the alignment of objects. A photoelectric device for controlling the coaxiality of the o6beKTOBj with the pyramid-shaped beam divider, photodetectors, and a recording unit is known. A disadvantage of the known device is the criticality of the beam-splitting element to the angle of inclination relative to the axis of the luminous flux, as well as high demands on the quality of manufacturing of the pyramid. The closest in technical terms to the invention is a photoelectric device for monitoring objects with axiality, which contains a beam splitter in the form of a bundle of optical fibers, one end of which is branched into four components - taps, photodetectors, along the path of light fluxes coming out of taps , -and registration block 1. A disadvantage of the known device is the impossibility of simultaneously controlling the alignment of objects at several points. The purpose of the invention is the ability to simultaneously control the alignment of objects at several points. This goal is achieved by the fact that in a photovoltaic device for controlling the coaxiality of objects containing a light divider, photodetectors and a recording unit, the beam divider is made in the form of light-conducting plates with beveled edges fixed diametrically opposite to two mutually perpendicular planes; Parts of the plates corresponds to the shape of the working platforms of the photodetectors. FIG. 1 is a schematic diagram of a photovoltaic device for controlling the coaxiality of objects; FIG. one; in fig. 3 is a section A-A in FIG. one.

A photoelectric device for controlling the coaxiality of objects includes a housing 1, inside of which is located a glass 2, in which a light is fixed, or a gel that is discharged in the form of light guiding plates 3, the shape of which parts correspond to the shape of working raio photodetectors 4 (round , square, etc.), cassette 5, cover 6, pressure ring 7, adjustment screws 10 8, cable 9 and recording unit (not shown).

To provide a tight connection with a centered object (not shown), the light guide plates 3 are attached to the walls of the opening of the cup 2, which with the aid of the clamp 6 and the clamping ring 7 is fixed in the housing 1, where the adjustment screws 8 are provided to ensure the alignment of the generator of the housing 1 and about 2 of the longitudinal axis of symmetry of the light-conducting plates 3. Fastening of the photodetectors 4. and the output parts of the light emitting plane; Tin 3 is carried out using a 5.25 cassette.

The device works as follows.

From a light source (not shown), a part of the light flux, U, freely passes through the device, and some of it falls onto the end areas of the light conducting plates 3, which are diametrically opposed in two mutually perpendicular cavities.

As it passes through the light guide plates 3, the shape of the rays is converted into the shape of the corresponding area of the photodetector 4, for example a circular one, after which each beam hits the corresponding photodetector 4, which converts the light energy into electrical energy. Electro-energy is transmitted via cable 9 to the recording unit. When the axis of the device deviates from the center of the light flux 10, light fluxes of varying intensity recorded by the recording unit will pass through the light conducting plates 3.

In the proposed device, along with the simplicity of the structures, it is possible to simultaneously control the coaxiality at several points along the axis of the luminous flux due to the fact that only a small part of the luminous flux is obscured by the ends of the light guide of the plates.
