In order to achieve the above object, the technical solution of the utility model is: a kind of electronic tensile machine stretching frock, comprise clamping part, sample installation portion and two sample fixture blocks, wherein clamping part is fixedlyed connected with the sample installation portion or is made as one, the sample installation portion is made up of cylindrical shell that is made as one and base, have radially handle hole on the cylindrical shell, the base middle part has axial hole, the sample fixture block is placed on the axially extending bore place of base, has spherical counterbore on the described base, spherical counterbore is communicated with axially extending bore, after merging, two sample fixture blocks are placed in the spherical counterbore, the cambered surface of spherical counterbore and the cambered surface of sample fixture block are complementary, and two sample fixture blocks merge its middle part, back and form the sample placed hole.
Described sample installation portion periphery also loose fit is set with sliding sleeve, have radially handle hole and circumferentially slippage slot on the sliding sleeve, on the sample installation portion screw is housed, the circumferential slippage slot that screw passes sliding sleeve is threaded with the sample installation portion, and the radially handle hole on the sliding sleeve can connect with the radially handle hole on the cylindrical shell.
Described sliding sleeve has base plate, and the base plate middle part has through hole, and the axial hole on the base of through hole and installation portion connects.
The beneficial effect that the utility model had is: owing to have spherical counterbore on the base, after merging, two sample fixture blocks are placed in the spherical counterbore, the cambered surface of spherical counterbore and the cambered surface of sample fixture block are complementary, therefore the interaction of the cambered surface of cambered surface by spherical counterbore and sample fixture block, can adjust the position of sample automatically, make the maintenance of sample upper and lower side coaxial, the test accuracy height, reduced machine work requirement simultaneously, reduced cost frock and sample; Also because the sample fixture block is convenient to change, therefore can test the sample of various ways, versatility is good, not only economy but also reasonable; The utility model also has clamping and saves time easy to operate, safe and reliable advantage in addition.
