Abstract

A Tensile strength detecting clamp of high strength bolt is formed by a nut clamp (1) and a bolt head clamp (2). One end of the nut clamp (1) is a bearing part with a square-shaped hole (3) and the other end is a mechanical clamping bolt head (4). The high strength bolt detecting clamp for tensile strength has the advantages that when screws with different diameters are detected, the screws with different diameters are fixed just by replacing the screw-in screws, the operation is convenient and efficient, the generality is improved and manufacturing cost is saved.

Description

A kind of high-strength bolt tensile strength detects anchor clamps
Technical field
The utility model relates to a kind of high-strength bolt tensile strength and detects anchor clamps, is applied to bolt machinery Performance Detection field.
Background technology
" GBT 1231-2006 high-strength large hexagon head bolt used for steel structure " regulation, the method for carrying out the tensile property detection of bolt is " GB/T 228-2002 metal material tensile test at room temperature method ".Owing to pressing the tension tester of GB/T 228-2002 standard manufacture, be mainly used in testing the materials such as reinforcing bar, the anchor clamps of its clamped sample are pincerlike, need clamping certain-length sample, just can carry out tensile property and detect.And when this class length of high-strength bolt sample short, that shape is special, intensity is large tested, pincer-like fixture easily causes sample to move or anchor clamps occurs and damages, cause detecting and be difficult to be undertaken by standard-required, therefore the high-strength bolt tensile property that must develop supporting tension tester special use detects anchor clamps, to satisfy high-strength bolt tensile strength testing requirement.
The utility model content
The purpose of this utility model is intended to develop a kind of high-strength bolt tensile property anchor clamps that can be used for tension tester.
The utility model is achieved through the following technical solutions:
A kind of high-strength bolt tensile strength detects anchor clamps, the utility model is characterised in that: anchor clamps are comprised of nut clamp and bolt head anchor clamps, nut clamp one end is the bearing member with shape of the mouth as one speaks hole, the other end is the mechanical grip bolt head, offers a U-shaped draw-in groove in the shape of the mouth as one speaks hole of described bearing member with shape of the mouth as one speaks hole; Bolt head anchor clamps one end is the bolt head with internal thread hole, and the other end is the mechanical grip bolt head; Between nut clamp and bolt head anchor clamps, be provided with set bolt, the bolt head of this set bolt is set to the sexangle steel pipe, this sexangle steel pipe is for the cover nut, bolt head at set bolt offers internal thread hole, the bolt head of set bolt partly is stuck in the shape of the mouth as one speaks hole of bearing member, and the bolt of set bolt partly screws in the internal thread hole of bolt head anchor clamps.
Above-mentioned U-shaped draw-in groove is pressed standard-required according to the difference of bolt to be measured and is selected width.
Each ingredient of the utility model is made of 45 hardened steel, when satisfying requirement of strength, reduces cost.
The beneficial effects of the utility model are, by the bolt part screw-on machine tool grip bolt head connection of set bolt, during test different-diameter bolt, only need to change screw-in bolt set bolt, the utlity model has convenient to usely, improve versatility, save the remarkable advantage of manufacturing cost.

Above-mentioned U-shaped draw-in groove is pressed standard-required according to the difference of bolt to be measured and is selected width.
Each ingredient of the utility model is made of 45 hardened steel, when satisfying requirement of strength, reduces cost.
Embodiment is as follows:
1) the mechanical grip bolt head 4 usefulness universal testing machine pincer-like fixtures 8 with nut clamp 1 are fixedly clamped.
2) bolt 7 bolt heads to be measured are snapped in the U-shaped groove of nut clamp 1 shape of the mouth as one speaks bearing member 3.
3) bolt 7 other ends to be measured are threaded in the internal thread of the set bolt 5 in the bolt head anchor clamps 2.
4) with the mechanical grip bolt head 6 that screws into bolt head anchor clamps 2 of set bolt 5.
5) regulate the position of universal testing machine pincer-like fixture 9, make it to aim at the mechanical grip bolt head 6 of bolt head anchor clamps 2, be fixedly clamped.
6) begin to detect.
