Description

one

The invention relates to testing mechanisms and is intended in materials science for stretching samples of materials, in particular biological, polymeric and composite materials, in X-ray chambers and diffractometers, for example, type DRON and CRM. . A known x-ray chamber provided with grips for securing the sample and a loading mechanism driving one of the grips C, 1}.

A known X-ray camera with a mechanism for stretching specimens, made in the form of a rigid body carrying a fixed grip, a spring loaded movable grip and a loading mechanism t2j.

The closest technical solution to the invention is a device for loading samples in an x-ray chamber, comprising a base carrying a loading mechanism with guides in which are mounted one-to-one clamps / sample, one of which carries a pressure nut 3J.

The disadvantage of this device is that the implementation of the loading mechanism makes it impossible to rotate the sample with respect to the direction of the X-ray beam, resulting in the loss of useful information.

The purpose of the invention is to expand the range of angles of rotation of the sample relative to the X-ray beam and to obtain more complete information in the process of radiography.

In order to accomplish this goal, a sample loading device in an x-ray chamber containing a base, carrying a loading mechanism with guides, in which the other grippers of the specimen, which are driven by one BHQ, are mounted, one of which carries a pressure nut, at least one elastic ring, on which the gripper guides are diametrically opposed. FIG. 1 shows a device for loading an X-ray diffractometer table, side view, a sectional view in FIG. 2 - the same, top view, In the grooves of the base 1 with the help of brackets 2, and screws 3 fastened -. Two elastic rings k, on which with the help of screws 5 the pad 6 is attached with the rod 8 freely sliding in the square section 7 hub. On the rod 8 by means of a nut 9 a force measuring sensor 10 is attached. To the rod 8 by means of an axis 11 a fixed grip is attached 12. In the block attached to the rings by means of screws J3, a loading level control unit, consisting of a crosspiece 15 with a screw 16, guide rods 17, a sleeve 18 and a holder 19, in the U-shaped grooves of which a roller 20, K of the cross bar is mounted 15 with the help of the axis 21 is fastened along Vision grip 22. The device operates as follows. In grippers 12 and 22, sample 2 is fixed with screws 23. Rotation of the roller 20 manually or with the help of an electric motor by moving the crosshead with the gripper in block 1 causes the sample to be loaded. Take out the roller 20, set up the device with the sample in the X-ray chamber and base 1 is attached to the goniometer table. The correction of the load during the X-ray diffraction study is carried out using a roller 20, which can be conducted through an opening in the wall of the x-ray chamber. To rotate the sample relative to the axis of the X-ray trigger, loosen the screws 3 and the rings with the sample are freely rotated in a plane perpendicular to their axis. To rotate the sample by 90, the holder 19 is detached, which is attached to the sleeve 18 with two screws 25 and the device is fixed to the base 1 by POMOTSII screws 3 on the base 1. The use of elastic rings simultaneously in the form of both the case and the loading element distinguishes the proposed device from the known ones, since it simplifies the design of the device and increases the range of applied loading means; The ability to rotate the loaded sample relative to the axis of the X-ray beam expands the scope of application of the device, in particular, allows the reference point of the sample to investigate the anisotropy of the mechanical properties and the heterogeneity of the structure of materials. Apparatus of the Invention A device for loading samples in an X-ray chamber, comprising a base carrying a loading mechanism with guides in which specimen clamps, one of which carries a pressure nut, are installed, one of which carries a pressure nut, with the aim of expanding angles of rotation of the sample with respect to the beam of Saint-rays and for obtaining more complete information, the loading mechanism is made in the form of at least one elastic ring on which diametrically oppositely ovany guiding grippers.
