Further, under the described extension spring tension test on two parallel arms of frock (2) diameter of every socket pin-and-hole different.
Further, in the described extension spring tension test frock (1) be connected under the extension spring tension test frock (2) with all keep after spring tension and compression testing machine is connected 90 ° vertical, frock (1) keeps plumbness with upper frock latch (3) in the described extension spring tension test, and frock (2) also keeps plumbness with lower frock latch (4) under the described extension spring tension test.
Further, have set bolt mounting hole (11) on the frock in the extension spring tension test (1), upper frock set bolt (5) is fixed on the spring tension and compression testing machine on the workplace by set bolt mounting hole (11).
Further, frock under the extension spring tension test also has the set bolt mounting hole on (2), and lower frock set bolt (6) also is fixed under the spring tension and compression testing machine on the workplace by the set bolt mounting hole.
Further, in the extension spring tension test under the set bolt mounting hole (11) of frock (1) and the extension spring tension test set bolt mounting hole of frock (2) be T-shaped through hole.
This extension spring tensile test fixture has following beneficial effect:
(1) the utility model is fixed on extension spring on the upper and lower frock latch on the upper and lower frock, therefore need not other servicing units, just can so that extension spring do not produce loosening or break off relations, and guarantee that extension spring tests accurately, efficiently reach the advantages such as easy to use.
(2) the utility model is owing to be provided with the latch that the different pin hole in aperture can be suitable for different size in upper and lower frock, thereby extension spring tensile test fixture latch size goes for the extension spring sample of different size.
