The electronic universal testing machine is used to test the tensile strength, tensile strength, breaking strength, elongation, elongation, shear strength and yield strength of aluminum alloy profiles under the condition of more than 35 ° C. The system adopts microcomputer closed-loop control, which has wide and accurate loading speed and measuring force range. It has high precision and sensitivity to the measurement and control of load and displacement. In daily use, the positioning error is often occurred, this different Chuck can be designed as a fixed axis, individual testing machine will have a stable Chuck Test, it is a certain amount of active space, in order to make the Chuck stable, we choose the chuck can be equipped with an additional ring, and other fixtures, because processing and assembly is likely to be resistance, once there is resistance is also very easy to wear, because the processing and assembly of the use is very easy to be resistance and wear, then such an axis positioning will produce a certain amount of error, we can keep the top and bottom two samples of the same axis processing, the Axis section of the center of the circle is not the same center, and its shape is also very easy to produce parallel, so that marks out is an s-shape shape, the sample of the Axis has a certain degree of angular adaptability, but the above and below the axis is not necessary to coincide, then this section will not appear bending problem.
In addition, when operating the electronic universal testing machine, whether the upper or lower materials will have this related needs, so when we use such a Chuck, these control equipment are we must take into account the position, the other test machine to add a Chuck product inside. This is a certain amount of activity gap, in order to test the product better control firm, we can also add a symmetrical ring products, which can be processed and assembly work, it can also reduce the danger of wasting time. When such a product is positioned on the same axis, there will definitely be errors. The formality of such a machine is very stable. Its upper and lower axes are all in parallel state, the center of the axis is not concentric, and there is also the danger of parallel displacement when testing the lower part. Such a marker is part of the material as if it were an S-line product, the sample head section of each product is adaptable, but the top and bottom axes do not coincide.
