Description

The invention relates to measuring equipment, in particular to devices for measuring the deformation of hollow elastic products of working bodies of tea-making machines.

A device for measuring the deformation of hollow elastic products containing a light source, a converter made in the form of a bundle of fiberglass fibers _1Q rigidly fixed to each other at one of the ends and connected to the light source, and a recording device connected to other ends of the fibers [ij. ₁₅ 'The closest to the invention in technical essence and the achieved result is a / device for measuring the deformation of hollow elastic products under shock loads, _m containing a transducer made in the form of fiber optic fibers, a registrar and a light source, one end of the optical fibers connected to a light source, and others - with a recorder [2J The disadvantage of these devices is the impossibility of measuring shock deformations in the working body of the tea-making machines directly during the working process, since in the cavity p Optical fibers protrude from both sides and, with its reciprocating movement, block access to tea shoots.

The purpose of the invention is the provision of measuring shock deformations of the working bodies of the tea-making machines directly during the working process.

This goal is achieved by the fact that the device for measuring the impact deformation of hollow elastic products under shock loads, containing a transducer made in the form of fiberglass fibers, a recorder and a light source, is equipped with mirrors, each fiber is made of a central and two peripheral ends which have co-i rectangular and half-forms and. rigidly connected bundles, some responsibly lindrical to each other, mirrors mounted along the optical Noch at a distance from these ends, other ends of the peripheral bundles connected to a light source, and the end of the central bundle to a recorder.

In FIG. 1 shows a schematic diagram of a device; in FIG. 2 fiber design.

The device comprises a light source 1, a converter made in the form of fiberglass fibers 2. Each fiber is made in the form of a central rectangular shape of a bundle 3 and two peripheral semi-cylindrical shapes of bundles. 4 and 5. One ends of the bundles 3 “5 are rigidly connected to each other and planted in the working body 6 of the tea assembly machine, and the others are connected to the light source 1 and the recorder 7 connected to the oscilloscope 8. The mirrors 9 are mounted along the optical beam at a distance from the ends. The harnesses are located in the protective case 10.

The device operates as follows.

From the source 1, the light enters the optical fibers 2, which illuminate the internal cavity of the working body 6 of the tea-picking machine, the image of the surface of the cavity is reflected on the mirror 9 and projected onto the input of the optical fibers 2. When the working body 6 is shock-deformed, its internal cavity changes in cross section, and the light the stream that is caught by the ends of the bundles 3, which transmit the image of the resulting picture through the branched ends to the recording device 7, connected to the oscilloscope 8.

The invention allows for / remote measurement of shock deformations of the working body when the fibers are located at one end, which ensures testing of the working bodies of the tea assembly machines when performing the technological process. The proposed device will allow you to choose the necessary rigidity of the working body, which will improve the quality of the collected material by about a factor and increase the productivity of the machine up to 15%.

cords, one ends of which have, respectively, rectangular and semi-cylindrical shapes and. rigidly interconnected, the caliper is mounted along the optical Yuma to the distance from these ends, the other ends of the peripheral harnesses are connected to the light source and the end of the central, the harness - to the recorder. FIG. 1 is a schematic diagram of the device; in fig. 2 structures of the light guide. The device contains a source of light 1, a converter made in the form of optical fibers 2 made of fiberglass. Each light guide is made in the form of a central rectangular shape of a burner 3 and two peripheral semi-cylindrical shapes of harnesses A and 5. Some ends of the harnesses 3-5 are rigidly connected to each other and planted in the working unit 6 of the tea-collecting machine, while others are connected to the light source 1 and the recorder 7 coupled to an oscilloscope 8. Mirrors 9 are positioned along the optical beam at a distance from the ends. The harnesses are located in a protective case 10. The device operates as follows. From source 1, the light enters the connections 2, which illuminate the internal cavity of the working body 6 of the paring machine, the image of the cavity surface is reflected on the mirror 9 and is projected onto the input of the optical fibers 2. When the working body 6 is subjected to shock deformation, its internal cavity changes in cross section the luminous flux varies, which is caught by the ends of the harnesses 3, which: transmit the image of the obtained picture through the branched ends to the recording device 7; connected to the oscilloscope 8. The invention allows for the remote measurement of the shock deformations of the working body at the location of the optical fibers from one end, which ensures the testing of the working bodies of tea-assembling machines during the technological process. The proposed device will allow to select the required rigidity of the working body, which will improve the quality of the collected material by about a factor of three and increase the productivity of the machine to 15.
