SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem provide an anchor clamps for centre gripping inspection metallographic specimen to solve the problem in the above-mentioned background art.
The utility model provides a technical problem adopt following technical scheme to realize:
a clamp for clamping and inspecting a metallographic specimen comprises an upper clamp plate and a lower clamp plate for clamping the metallographic specimen, wherein an upper mounting hole for a bolt head of a first bolt and a bolt head of a second bolt to penetrate is formed in the upper clamp plate, a lower mounting hole for a bolt body of the first bolt and the bolt body of the second bolt to penetrate is formed in the lower clamp plate, the aperture of the upper mounting hole is larger than that of the lower mounting hole, an internal thread matched with the external thread on the bolt body of the first bolt and the bolt body of the second bolt is formed in the lower clamp plate in the lower mounting hole, so that the metallographic clamp is effectively fixed, and the upper clamp plate is not internally provided with the internal thread so as to be adjusted left and right along with the first bolt and the second bolt and be conveniently matched with the clamping of the metallographic specimen with different thicknesses; and meanwhile, the centers of the upper mounting hole and the lower mounting hole are positioned on the same central axis, so that the smooth assembly of the first bolt and the second bolt is ensured.
The utility model discloses in, the punch holder is planar structure with the lower plate, and 40mm × 20mm, thickness 3mm are set for to the punch holder with the lower plate size.
The utility model discloses in, punch holder and lower plate are square or ring shape structure to the metallographic specimen piece that adapts to different specifications.
The utility model discloses in, upper plate and lower plate adopt carbon element structural steel to make.
The utility model discloses in, a bolt and No. two bolts adopt stainless steel material to make to prevent that a bolt and No. two bolt corrosion from causing the punch holder to remove unsmoothly.
Has the advantages that: the utility model discloses well metallographic specimen is firmly fixed by the clamping between two splint through bolt and splint, and handheld this anchor clamps polishes on burnishing and polishing machine, effectively solves the manual difficulty of holding between the fingers metallographic specimen, can once a plurality of metallographic specimen of centre gripping, has alleviateed inspector's intensity of labour greatly, improves the polishing efficiency and the polishing quality of metallographic specimen, and then practices thrift manufacturing cost, shortens the cycle of metallographic specimen polishing.

Fig. 1 is a schematic structural diagram of a preferred embodiment of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Referring to fig. 1, a clamp for clamping and inspecting a metallographic specimen comprises an upper clamp plate 1, a lower clamp plate 2, a first bolt 3 and a second bolt 4, wherein an upper mounting hole for penetrating a bolt head of the first bolt 3 and the second bolt 4 is formed in the upper clamp plate 1, a lower mounting hole for penetrating a bolt body of the first bolt 3 and the second bolt 4 is formed in the lower clamp plate 2, the aperture of the upper mounting hole is larger than that of the lower mounting hole, an internal thread matched with an external thread on the bolt body of the first bolt 3 and the second bolt 4 is formed in the lower clamp plate 2 in the lower mounting hole, so that the effective fixation of the clamp is ensured, and the upper clamp plate 1 is not internally threaded so as to be adjusted left and right along with the first bolt 3 and the second bolt 4 and be conveniently matched with the clamping of metallographic specimen with different thicknesses; meanwhile, the hole centers of the upper mounting hole and the lower mounting hole are positioned on the same central axis, so that the smooth assembly of the first bolt 3 and the second bolt 4 is ensured;
in the embodiment, the upper splint 1 and the lower splint 2 are of a planar structure, and the size of the upper splint 1 and the lower splint 2 is set to 40mm × 20mm, and the thickness is 3 mm;
in the embodiment, the upper clamping plate 1 and the lower clamping plate 2 are made of A3 carbon structural steel,
in the embodiment, the first bolt 3 and the second bolt 4 are made of stainless steel material 1Cr17Ni2 to prevent the upper clamp plate 1 from moving unsmoothly due to corrosion of the first bolt 3 and the second bolt 4.
In this embodiment, when the device is used, a first bolt 3 and a second bolt 4 are inserted into an upper mounting hole of an upper clamp plate 1, the upper clamp plate 1 is tightly attached to bolt heads of the first bolt 3 and the second bolt 4, then a metallographic specimen is tightly attached to the upper clamp plate 1 and placed in the upper clamp plate, and finally a bolt body of the first bolt 3 and the second bolt 4 is inserted into a lower mounting hole of a lower clamp plate 2 and is fastened with the first bolt 3 and the second bolt 4, so that the metallographic specimen is tightly fixed by the upper clamp plate 1 and the lower clamp plate 2 and cannot fall off;
