Abstract
The utility model discloses a stranded steel wire tensile strength fixture which is used for clamping a stranded steel wire sample, prevents the stranded steel wire sample from skidding or being fractured in a root portion in a test process, and can improve authenticity and accuracy of detection of test equipment. The stranded steel wire tensile strength fixture comprises a fixture body, a jaw clamping board and a fixture head oil cylinder, wherein the jaw clamping board comprises a left piece and a right piece which are respectively fixed inside guide grooves of the fixture body. Vertical moving of the fixture head oil cylinder is used to jack a fixture head oil cylinder tray, so that the jaw clamping board can vertically move inside the V-shaped guide groove of the fixture body, roller pins are installed inside the guide grooves at two sides of the jaw clamping board, two straight grooves are installed inside V-shaped grooves of the jaw clamping board, and gear racks are installed in the straight grooves.
Description
Technical field
The utility model relates to the universal testing machine in a kind of test unit field, is specifically related to a kind of steel hinge line pulling strengrth and detects anchor clamps.
Background technology
Steel strand wires are a kind of novel building materialss; Be widely used in fields such as large bridge, highway, building construction, ground anchorage, coal mine support; Universal testing machine is when doing the steel hinge line tensile strength test; Need add and hold the steel hinge line sample, hold sample and rupture at root to prevent that steel hinge line from skidding and adding in process of the test, this will use steel hinge line pulling strengrth anchor clamps.
The utility model content
The utility model technical matters to be solved provides a kind of steel hinge line pulling strengrth anchor clamps of be applied to stretch universal testing machine and similar large-scale experiment equipment; Be used for adding and hold the steel hinge line sample; Preventing that steel hinge line from skidding or adding in process of the test holds sample and ruptures at root, can improve authenticity and accuracy that testing equipment detects.
The utility model adopts the basic design of technical scheme to be: a kind of steel hinge line pulling strengrth anchor clamps comprise clamp body, jaw clamp, chuck oil cylinder, about the jaw clamp divides two; Be separately fixed in the clamp body gathering sill; With the chuck oil cylinder move up and down jack-up chuck oil cylinder pallet, the jaw clamp is moved up and down in the V-shaped groove of clamp body, in the gathering sill of jaw clamp both sides needle roller is housed; Two straight troughs are set respectively in the jaw clamp V-shaped groove, and the tooth bar is installed on the said straight trough.
The beneficial effect of the utility model is; In the gathering sill of jaw clamp both sides needle roller is housed; Friction force in the time of can reducing the jaw clamp and in the V-shaped groove of clamp body, move up and down; Two straight troughs are set in order to the tooth bar to be installed in the jaw clamp V-shaped groove respectively, this tooth bar can guarantee that universal testing machine reliably adds and hold the steel hinge line sample, when destroying, can prevent that steel hinge line from skidding in test stretching maximum, force when doing the steel hinge line tensile strength test.
