Tension detecting device

Abstract

The invention discloses a tension detecting device, comprising an upper pressing plate, a lower pressing block, paired bolts and a connecting screw rod, wherein the upper side face of the lower pressing block is provided with a square slot for communicating the left side face and the right side face of the lower pressing block, and the upper pressing plate and the lower pressing block are fixed through the bolts; the lower side face of the square slot and the lower side face of the upper pressing plate positioned on the lower side face of the square slot form a seal face of the upper side face and the lower side face of a detected fixed part; the paired bolts are respectively positioned on opposite positions at front and back sides of the square slot; and the left end of the connecting screw rod is fixed with the lower pressing block through a threading structure, the right end of the connecting screw rod is fixed with a measuring head of a tensometer through a threading structure, and the central axis of the connecting screw rod is consistent with the central axis of the measuring head of the tensometer. The tension detecting device disclosed by the invention has a simple structure and is convenient to use; and by adopting the tension detecting device, the detected fixed part can be ensured to be effectively fixed without generating additional force on a detected movable part, the accuracy of the force application direction can be improved when the detected part is detected, the measurement process is convenient, and the measurement precision is improved.

Description

technical field [0001] The invention relates to a tension detection device, in particular to a tension detection device suitable for use with a tension meter. Background technique [0002] Tension gauge is a small and simple thrust and tension testing instrument; it has the advantages of high precision, easy operation and portability, and has a peak value switching operation knob, which can be used for peak load indication and continuous load value indication. In the factory, a tension meter is often used to perform simple tensile performance tests on products or parts; when in use, fix the fixed part with the measuring head of the tension meter, and pull the movable part along the central axis of the tension meter measuring head to obtain the measurement result . The measuring head of the tension meter has a spiral structure, and the parts used to fix the measuring head and the fixing parts are generally hooks. In actual operation, it is often necessary to add other parts ...

AI Technical Summary

Problems solved by technology

The measuring head of the tension meter has a spiral structure, and the parts used to fix the measuring head and the fixing parts are generally hooks. In actual operation, it is often necessary to add other parts such as wires to fix the connection, which is troublesome to operate and difficult to ensure. The direction of the final force is consistent with the direction of the central axis of the measuring head
