Abstract

The utility model relates to a tensile strength detecting clamp of a double thread screw. The tensile strength detecting clamp of the double thread screw is formed by two screw clamps (1, 1') in the same structure and in reverse and symmetrical connection with each other. Two ends of the screw clamps (1, 1') are respectively provided with screw-in screws (3, 3') and mechanical clamping screws (4, 4'), the screw-in screws (3, 3') are all hexagonal steel pipes, internal threads are installed inside the pipes. The screw-in screws (3, 3') are connected with screw holes (2, 2') arranged in the heads of the mechanical clamping screws (4, 4') in screw thread fit. The diameters of the internal threads can be selected according to different standard requirements of the to-be-detected screw. The screw-in screws are provided with threads at the end and are connected with the mechanical clamping screws through the threads at the end. 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 two-flight screw tensile strength detects anchor clamps
Technical field
The utility model belongs to two-flight screw tensile strength and detects the clamp structure technical field, is applied to the screw rod mechanism Performance Detection.
Background technology
" GB/T3098.1-2010 securing member mechanical property---bolt, screw and double-screw bolt " regulation, the method for carrying out the tensile property detection of screw rod is " metal material tensile test at room temperature method " GB/T 228-2002.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 there is screw thread at the two-flight screw two ends, and intensity is larger, during pincer-like fixture clamping screw rod, easily be moved, or cause screw rod and anchor clamps to damage, cause detection to be difficult to be undertaken by standard-required, the two-flight screw tensile property that therefore must develop supporting tension tester special use detects anchor clamps, to satisfy two-flight screw tensile strength testing requirement.
The utility model content
The purpose of this utility model is intended to develop a kind of two-flight screw tensile strength that can be used for tension tester and detects anchor clamps.
The utility model is achieved through the following technical solutions.
The utility model by the screw rod anchor clamps of two parts same structure each other reverse symmetry connect to form; The two ends of screw rod anchor clamps arrange respectively screw-in screw and mechanical grip screw, the screw-in screw is the sexangle steel pipe, be provided with internal thread in pipe, this sexangle steel pipe is used for the cover nut, and the screw-in screw carries out threaded engagement by the screw hole of opening and connects on mechanical grip screw head of screw.
The utility model can be pressed standard-required according to the difference of bolt to be measured and select internal thread diameter, and afterbody has screw thread, screws in mechanical clamp screws by tailing screw flight and connects.
Each ingredient of the utility model screw rod anchor clamps is made of 45 hardened steel.
The utility model can be pressed standard-required according to the difference of bolt to be measured and select internal thread diameter, and afterbody has screw thread.Screwing in mechanical clamp screws by tailing screw flight connects.During test different-diameter bolt, only need to change the screw-in screw and be fixed, convenient to use, improve versatility, save manufacturing cost.
All parts of the utility model are made of forged steel.

The utility model can be pressed standard-required according to the difference of bolt to be measured and select internal thread diameter, and afterbody has screw thread, screws in mechanical clamp screws 4 by tailing screw flight and connects.
Each ingredient of the utility model screw rod anchor clamps is made of 45 hardened steel.
The utility model embodiment is as follows:
1) the mechanical grip screw 4 with screw rod anchor clamps 1 adopts universal testing machine pincer-like fixture 5 to be fixedly clamped.
2) screw rod 7 threaded one ends to be measured are screwed in the internal thread of screw-in screw 3 of screw rod anchor clamps 1.
3) in the screw hole that screws into screw rod anchor clamps 12 with screw-in screw 3.
4) screw rod 7 other ends to be measured are threaded into screw-in screw 3 ' internal thread in.
5) with screw-in screw 3 ' screw into screw rod anchor clamps 1 ' screw hole 2 ' in.
6) regulate universal testing machine pincer-like fixture 5 ' the position, make it to aim at screw rod anchor clamps 1 ' mechanical grip screw 4 ', be fixedly clamped.
7) begin to detect.
