Problems solved by technology

However, there are some unsatisfactory places in the composite mandrel torsion testing machine currently on the market: or the power transmission depends on gears and chains, and the mechanism is bulky and complicated; or the clamping method uses a chuck, the clamping area is small, and the clamping force is small. Hold, it will slip, the sample mandrel will rotate or slide axially, and the clamping force will damage the sample mandrel, so that the sample mandrel will be damaged before the test starts, reducing the accuracy of the test ; or limited by the structure of the equipment, only short-length samples can be tested, which is difficult to meet the testing requirements of products of different specifications
In short, the current torsion testing machine on the market is difficult to meet the large-scale torsion test of the composite mandrel, so there is an urgent need for a sample with a simple structure, good and reliable clamping effect, and a length that can meet various mandrel specifications. A new type of torsion testing machine with detection requirements, convenient operation and low cost

Abstract

The invention provides a composite core rod torsion tester. The tester comprises a workbench, a power system, a front clamping component, a rear clamping component and a tension mechanism. When the tester is used for testing, a sample core rod is used for clamping and positioning by utilizing the taper through the front and rear clamping components, so that the clamping acts stably and reliably, and cannot destroy the core rod. The whole equipment is compact in structure, concise, economical and practical, and is convenient to operate, so that a convenient and reliable testing means is provided for detecting the torsion performance of a core rod.

Description

technical field [0001] The invention belongs to the technical field of material testing machines, and in particular relates to a composite mandrel torsion testing machine, which uses a simple device to test and evaluate the torsion resistance of a composite mandrel. Background technique [0002] At present, with the rapid development of the power industry, the application of new composite core cables is imminent, and the torsional load performance of composite core rods has become an important indicator for evaluating the quality of composite core cables. However, there are some unsatisfactory places in the composite mandrel torsion testing machine currently on the market: or the power transmission depends on gears and chains, and the mechanism is bulky and complicated; or the clamping method uses a chuck, the clamping area is small, and the clamping force is small. Hold, it will slip, the sample mandrel will rotate or slide axially, and the clamping force will damage the sa...
