Detailed description of the invention
Embodiments of the invention 1, as represented in figures 1 through 14: cylindricality metallographic specimen clamp includes left plate 1 and right plate 2.Left plate 1 side close to each other with right plate 2 is provided with grip orifice 3, and in the top and bottom of fixture, end is provided with at clamp system, the other end and is provided with elastic ring set 5.
In the present embodiment, the lower end of fixture is located at by clamp system, and the upper end of fixture is located at by elastic ring set 5.In other embodiments, it is also possible to exchanged with the position that elastic ring overlaps by clamp system, the upper end of fixture is located at by clamp system, and elastic ring is sheathed on the lower end of fixture.
Grip orifice 3 is made up of arc groove, and when the present embodiment, the radian of arc groove is 180 degree, i.e. cross section is semicircle；In other embodiments, any radian in the range of arc groove can also be 90-180 degree.
In left plate 1 and right plate 2 one be provided with overlap for being set with elastic ring one end adjustable column 61, another be provided with for be set with elastic ring set the other end mounting groove 7.In the present embodiment, adjustable column 61 is located at left plate, and mounting groove 7 is located on right plate.In other embodiments, it is also possible to being located on right plate for adjustable column, mounting groove is located on left plate.
Adjustable column 61 has telescopic first spring 62 in left and right near the end connection of mounting groove 7, and the first spring 62 is used for driving adjustable column to move left and right.The installing hole 63 that left and right is run through is offered on left plate 1, pre-and post perforative resigning hole 64 it is further opened with on left plate 1, the elongated hole that this resigning hole 64 extends in left-right direction for aperture length, installing hole 63 includes small-bore section 631 and large aperture section 632 the most successively, resigning hole 64 connects with small-bore section 631 and is vertical setting, adjustable column about 61 extends, and adjustable column 61 is turned left from the right side the big footpath section 611 including coordinating with large aperture section 632 inserting successively and the path section 612 coordinated with small-bore section 631 inserting.The left end of path section 612 stretches in resigning hole 64, first spring 62 is located in large aperture section 632, being installed with stopper 65 at the right output port of large aperture section 632, the left end of the first spring 62 pushes up press-fit with right side top press-fit, right-hand member and the stopper 65 of the first spring 62 of big footpath section 611.Between stopper 65 and left plate 1 with bolts, it would however also be possible to employ pin connect.In other embodiments, it is also possible to save the first spring.
