Embodiment
Embodiments of the invention 1, as shown in Fig. 1-14: cylindricality metallographic specimen clamp comprises left plate 1 and right plate 2.The mutual close side of left plate 1 and right plate 2 is provided with and clamps mouth 3, and in the top and bottom of fixture, one end place is provided with clamp system 4, other end place is provided with elastic ring cover 5.
In the present embodiment, clamp system 4 is located at the lower end of fixture, and elastic ring cover 5 is located at the upper end of fixture.In other embodiments, the position of clamp system and elastic ring cover can also be exchanged, clamp system is located at the upper end of fixture, and elastic ring is sheathed on the lower end of fixture.
Clamp mouth 3 and be made up of arc groove, in the time of the present embodiment, the radian of arc groove is 180 degree, and cross section is semicircle; In other embodiments, arc groove can also be any radian within the scope of 90-180 degree.
In left plate 1 and right plate 2 one is provided with adjustable column 61 for being set with elastic ring cover one end, another is provided with the mounting groove 7 for being set with the elastic ring cover other end.In the present embodiment, adjustable column 61 is located at left plate, and mounting groove 7 is located on right plate.In other embodiments, can also be located on right plate for adjustable column, mounting groove is located on left plate.
