Abstract

The utility model relates to devices for marking cylindrical specimens for static tension using scribers located at equal distances from one another. The device for applying scores to cylindrical specimens comprises a main solid part and a part provided with lugs for connecting the main solid part and the part by means of a bolted connection, a part for mounting the specimen, provided with an internally threaded hole and notches, clamped between the main solid part and the part, and scribers. The main solid part is provided with a rack having a hole with an internal thread, into which scribers are screwed. The main solid part and the part are provided with clamps for forming a tongue-and-groove connection with the notches. The technical result of the utility model is the ability to adjust the device to a specific size and shape of the specimen. 7 Fig.

Description

[0001] The utility model relates to devices for marking cylindrical samples for static tension using scribers located at equal distances from each other.

[0002] Known similar devices SU 148532 A1 “Device for marking samples” and SU 129024 A1 “Device for marking tensile samples” do not meet the requirements due to the inability to mark cylindrical samples that have wider gripping heads compared to the working part of the sample, and also do not have sufficient marking accuracy and unification.

[0003] The proposed development allows for the adjustment of the device to a specific size and shape of the sample, marking with sufficient accuracy and in accordance with the specific requirements of regulatory testing documentation, and reducing the overall testing time for a batch of samples by eliminating the operation of reinstalling various devices to a specific sample size.

[0004] The objective of the claimed utility model is to create a device with sufficient accuracy, reliability and adjustability, which will allow:

[0005] - to mark cylindrical samples with heads;

[0006] - maintain the required marking accuracy;

[0007] - to mark samples from materials with different hardness;

[0008] - to mark samples with different sizes.

[0009] The technical result of the utility model is the creation of a design for a device for marking cylindrical samples.

[0010] The stated tasks are solved, and the technical result is achieved by creating a device design that allows for its adjustment for cylindrical samples of various sizes, equipped with gripping heads, to perform adjustment of the device to the requirements of various regulatory documents, having the function of quickly replacing scribers for materials of different hardness, and also to reduce the overall time for marking a batch of samples by eliminating the operation of reinstalling various devices for a specific sample size.

[0011] The claimed device for applying marks to cylindrical samples is explained by:

[0012] fig. 1 - device drawing;

[0013] Fig. 2-5 - device detailing;

[0014] Fig. 6 - general view of the device.

[0015] The device consists of a main integral part 1, which has a rail 2 with holes with an internal thread 3, intended for installing marking scribers with an external thread 4 and a cross-shaped notch 5, intended for tightening with a screwdriver, a part 6, having an internal threaded hole 7, intended for installing a sample, notches 8, intended for installing clamps 9 in them, intended for forming a tongue-and-groove connection and ensuring fixation and rotation of the device around the axis of the sample, lugs 10, intended for connecting parts 1, 6 and 11 with a bolted connection 12.

[0016] The operating principle of the claimed device for applying marks to cylindrical samples is shown in Fig. 7.

[0017] The specimen is screwed into hole 7 of part 6, after which it is clamped by parts 1 and 11, creating a tongue-and-groove connection using notches 8 and clamps 9. The device is connected by bolt connection 12. Scribers 4 are screwed into holes 3 of rail 2 of part 1 in the required number, depending on the length of the specimen. The clamping device is then clamped in vice 13. Scribers 4 are screwed until they contact the surface of the specimen, after which the device begins to rotate around the axis of the specimen.
