The utility model discloses change the fixed chuck of original anchor clamps into fixed little chuck and a plurality of removable combination of trading formula chuck ring, removablely trade the concentric and laminating installation with little chuck of formula chuck ring, come the realization to the test of the annular sample of different thickness through the removable formula chuck ring that trades of changing different external diameters, can reduce annular sample deviation range to 0.2 millimeter, satisfied the multiple test requirement in the real production and improved test efficiency.
Description
Technical field
The utility model belongs to drawing pipe tool technical field, is specifically related to a kind of fixture for tubing hoop tensile test.
Background technology
GRP pipe is with glass fibre and goods thereof as reinforcing material, the pipeline made for matrix material with unsaturated polyester resin, GB/T21238-2007 " chamber for fibre-reinforced plastics sand inclusion pipe " defines glass fiber reinforced plastic sand-inclusion pipeline should carry out initial hoop tensile strength test.Test uses fluid pressure type or electronic type testing machine for mechanical properties, and testing machine connects the hoop tensile test fixture matched, and Both ring sam can be carried out tension test.At present, the more commonly used stretching clamp has following structure, and hoop stretching clamp has fixing semicircle chuck, fitting with sample internal diameter, at the trial, upper and lower two fixtures separate, separation process applies the power of both direction up and down respectively to ring specimen, so that sample destroys；The internal diameter size of existing sample typically requires to be 150 ± 0.2 millimeters, width is 6 ± 0.2 millimeters, thickness is 1.5 or 3 millimeters, semicircle chuck is 148～150 millimeters with the position diametric requirements of sample internal diameter laminating, it combines the most just, carrying out scientific research, during the most rigorous test, the machining accuracy of sample is controlled the most rigorous, above-mentioned fixture can be suitable for, but in the test of actual production, the preparation of sample tends not to comply fully with the regulation of standard, slightly beyond the deviation of regulation, will install to sample and cause difficulty, even cannot install, impact produces and the efficiency of test.
More than for, as the research and development technology personnel of the industry, it is highly desirable to design a fixture for tubing hoop tensile test, it is possible to be fully solved above drawback, improves test and production efficiency.
Summary of the invention
For overcoming the existing technical drawback of hoop stretching clamp, the utility model has carried out following improvement, its technical scheme is as follows: a kind of fixture for tubing hoop tensile test, it includes a connecting shaft, connecting shaft bottom and jig main body weld or are bolted to one, described jig main body is semicircle shape, on jig main body, its lowermost end is designed with the little chuck of a semicircle shape, little chuck and jig main body are integral type, little chuck be provided above a dismountable card disk ring, the both sides of dismountable card disk ring are provided with fixing hole；The gap of the arcuation between dismountable card disk ring and jig main body is for placing the sample of annular.
Described dismountable card disk ring and little chuck concentric design.
Described dismountable chuck ring design is multiple, and all of internal diameter of dismountable card disk ring matches with the external diameter of little chuck, and the diameter of the external diameter of dismountable card disk ring is gradually increased with 0.2 millimeter.
The beneficial effects of the utility model: the utility model is by using above structure, the fixed chuck of original fixture is changed into fixed little chuck and the combination of multiple dismountable card disk ring, dismountable card disk ring is concentric with little chuck and installation of fitting, the test of the ring specimen to different-thickness can be realized by changing the dismountable card disk ring of various outer diameter, because the diameter of the external diameter of dismountable card disk ring is gradually increased with 0.2 millimeter, the deviation range of ring specimen diameter can be tapered to 0.2 millimeter, meet the multiple test requirements document during reality produces and improve test efficiency.
Accompanying drawing explanation
The utility model has accompanying drawing 3 width, wherein:
Fig. 1 is that the utility model stereochemical structure splits schematic diagram.
Fig. 2 is the utility model dismountable chuck ring structure schematic diagram.
Fig. 3 is the utility model package assembly schematic diagram.
In accompanying drawing: 1, connecting shaft, 2, jig main body, 3, sample, 4, dismountable card disk ring, 5, little chuck, 6, bolt, 7, fixing hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further described through.As shown in drawings, a kind of fixture for tubing hoop tensile test, it includes a connecting shaft 1, connecting shaft 1 bottom and jig main body 2 weld or are bolted to one, and described jig main body 2 is semicircle shape, on jig main body 2, its lowermost end is designed with the little chuck 5 of a semicircle shape, little chuck 5 and jig main body 2 are integral type, little chuck 5 be provided above a dismountable card disk ring 4, the both sides of dismountable card disk ring 4 are provided with fixing hole 7；The gap of the arcuation between dismountable card disk ring 4 and jig main body 2 is for placing the sample 3 of annular, when the utility model assembles and makes, dismountable card disk ring 4 and little chuck 5 concentric design, dismountable card disk ring 4 is designed as multiple, the internal diameter of all of dismountable card disk ring 4 matches with the external diameter of little chuck 5, and the diameter of the external diameter of dismountable card disk ring 4 is gradually increased with 0.2 millimeter.
When the utility model uses; as shown in Figure 3; supported the use up and down by two sleeve clamps; the dismountable card disk ring 4 of various outer diameter size chosen by the sample 3 of the annular according to different-thickness; can closely cooperate with dismountable card disk ring 4 after guaranteeing sample 3 assembling of annular; the sample 3 of annular is tucked in the gap of the arcuation between dismountable card disk ring 4 and jig main body 2; by outer liquid pressure type or the force tractive up and down of electronic type testing machine for mechanical properties; the sample 3 making annular destroys, and completes tubing hoop tensile test with this.
By using above structure, the fixed chuck of original fixture is changed into fixed little chuck 5 and the combination of multiple dismountable card disk ring 4 by existing tool, by changing the test that the dismountable card disk ring 4 of various outer diameter realizes the sample 3 of the annular to different-thickness, because the diameter of the external diameter of dismountable card disk ring 4 is gradually increased with 0.2 millimeter, can be by the sample bias range reduction to 0.2 millimeter of annular, meet the multiple test requirements document during reality produces and improve test efficiency, being the fixture of a kind of preferable tubing hoop tensile test.
