Embodiment Construction

[0015] specific implementation plan

[0016] Said invention consists of figure 1 The overall structure diagram of the material testing machine, figure 2 Partial cross-sectional view of quantitative tension and compression loading machine base.

[0017] Its loading method is weight loading.

[0018] The specific function realization of this test device is as follows:

[0019] Quantitative tensile loading action process: firstly, the loading support machine 7 is fixed on the corresponding position on the fixed base 4 through the tightening screw 13, and then one end of the test piece 3 is fixed on the pin hole 5, if the experimental condition is to realize the loading of the hinged test piece , it is fixed on the pin hole, otherwise, the test piece 3 is fixed on the pin hole 5. The other end of the workpiece is fixedly placed in the guide groove in the loading support frame 7, and the test piece 3 is fixed by passing through the guide slider 12 through the guide groove with...

Abstract

The invention relates to a quantitative tension and compression testing device which belongs to the technical field of material testing. The device comprises a fixed base, a support stand, a loading support stand, a quantitative tension and compression rod and three fixed pulleys. The device has simple structure, can be used together with other testing instruments, has strong extension applicability, and realizes very high testing precision and larger loading and moment increase by ingeniously arranging the positions of the three fixed pulleys and the length ratio of the tension and compression rods with geometric and leverage principles. The positions of the three fixed pulleys must be relatively on the same circular arc with a round pin hole at the middle part of a quantitative loading rod; and when a weight is quantitatively loaded and applied, the three fixed pulleys are still on the same circle of center so as to fully ensure the loading precision. The length ratio of quantitative loading rods A and B decides the loading torque ratio.

Description

technical field [0001] The invention belongs to the technical field of material testing, and in particular provides a quantitative tension-compression material testing mechanism with simple structure. Background technique [0002] With the development of industrial technology, the requirements for various mechanical properties of materials are getting higher and higher, which requires accurate testing of materials, and correspondingly increases the requirements for the performance of experimental instruments. At present, this type of equipment is mainly weight-type constant load tensile testing machine (or computer-controlled material tensile testing machine or universal testing machine) and force measuring ring (or spring device). The former test is accurate, but the equipment is expensive and occupies a large area, and it is inconvenient to carry and place; the latter has a simple structure, low price, and is suitable for batch tests, but the test accuracy of the device is...
