The tool is installed on an axial force sensor, two ends of the axial force sensor are respectively provided with a deep hole and a shallow hole, the tool comprises sleeves respectively arranged on two ends of the axial force sensor, a first washer and a clamp arranged in the sleeves, wherein the outer surface of thesleeves is matched with the deep hole of the axial force sensor, a sleeve step hole is arranged in an inner cavity of the sleeves, namely, a first hole and a second hole, and a plurality of grooves are evenly distributed on the inner wall of the first hole. The tool has the characteristics of low manufacture cost, wide application range and the like.

Description

A kind of instrument that is used for the test fastener torque coefficient
Technical field
The utility model relates to a kind of securing member performance testing tool, relates in particular to a kind of instrument that is used for the test fastener torque coefficient.
Background technology
Total institute is known, and torque coefficient is the emphasis examination object of steel construction product, also plays a part very important in installation process.How to measure torque coefficient accurately and not only depend on the machine for testing torsion performance, test mould also plays an important role.The machine for testing torsion kind is a lot of in the Investment in fastener industry now, but they have a common ground, and that is exactly that this easily causes wasting of resources phenomenon aborning according to the whole unit clamp of each specifications design one cover.Therefore, prior art can not satisfy the product test requirement of enterprise.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of instrument that is used for the test fastener torque coefficient, to reach the reduction manufacturing cost, enlarges the purpose of the scope of application.
A kind of instrument that is used for the test fastener torque coefficient described in the utility model, be installed on the axial force sensor, the two ends of this axial force sensor offer a deep hole and a shallow bore hole respectively, described instrument comprises that the sleeve, first packing ring and that are separately positioned on described axial force sensor two ends are arranged on the anchor clamps in the described sleeve
The outside surface of described sleeve and the deep hole of described axial force sensor are complementary, and the inner chamber of described sleeve offers a sleeve stepped hole, i.e. first hole and second hole, and be evenly equipped with several grooves on the inwall in this first hole;
The outside surface of described first packing ring and the shallow bore hole of described axial force sensor are complementary;
The inner chamber of described anchor clamps offers an anchor clamps stepped hole that agrees with mutually with tested described securing member outside surface, and the outer peripheral face of these anchor clamps is provided with the convex tendon that several and described groove are complementary.
At the above-mentioned instrument that is used for the test fastener torque coefficient, described instrument also comprises second packing ring that is arranged between described sleeve and the anchor clamps.
Owing to adopted above-mentioned technical solution, the utility model to adopt sleeve and the combined structure of anchor clamps, in use, only needed to change corresponding anchor clamps, thereby saved starting material greatly according to the specification of tested securing member; In addition, can between sleeve and anchor clamps, add second packing ring as required, thereby can free adjustment carry reach, therefore have advantage of wide range of application so that reach the measurement standard requirement.
Description of drawings
Fig. 1 is a kind of structure side view that is used for the instrument of test fastener torque coefficient of the utility model;
Fig. 2 is that the utility model is installed in the constitutional diagram on the axial force sensor.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
See also Fig. 1, Fig. 2, the utility model, it is a kind of instrument that is used for the test fastener torque coefficient, comprise that the sleeve 1, first packing ring 3 and that are installed in axial force sensor 10 two ends respectively are arranged on the anchor clamps 2 in the sleeve 1, wherein, the two ends of axial force sensor 10 offer a deep hole 101 and a shallow bore hole 102 respectively
The deep hole 101 of the outside surface of sleeve 1 and axial force sensor 10 is complementary, and the inner chamber of sleeve 1 offers a sleeve stepped hole, i.e. first hole 11 and second hole 12, and be evenly equipped with several grooves 13 on the inwall in this first hole 11;
The shallow bore hole 102 of the outside surface of first packing ring 3 and axial force sensor 10 is complementary;
The inner chamber of anchor clamps 2 offers the anchor clamps stepped hole 21 that agrees with mutually with tested securing member outside surface, and the outer peripheral face of these anchor clamps 2 is provided with the convex tendon 22 that several and groove 13 are complementary, thereby be fixed in the sleeve 1, anchor clamps 2 can be according to the diameter specifications manufacturing of tested securing member.
In the utility model, also can between sleeve 1 and anchor clamps 2, add the second pad figure (not shown), thereby the tested fastener threads length of energy free adjustment carrying be so that reach the measurement standard requirement as required.
When the utility model uses, the anchor clamps 2 that accompany tested securing member are packed in the sleeve 1, make the end with screw thread of this securing member stretch out sleeve 1, and pass the axial force sensor 10 and first packing ring 3 successively, be fixed with the nut (not shown) at last.Sleeve 1 bears clamping force in the test with first packing ring 3, and transmits clamping load and give axial force sensor 10, thereby carries out the measurement of torque coefficient.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
