The utility model also adopts the structure comprising a clamp tool seat and a plurality of retainers, and is characterized in that the clamp tool seat is a metal block with a screw through hole in the center, the diameter of the screw through hole is larger than the diameter of the ground metallographic specimen, the retainer is a groove flat end cylindrical bolt which is screwed in the screw through hole, the cylindrical bolt lower end absorbs the permanent magnet, and the diameter of the permanent magnet is smaller than the diameter of the screw through hole. The utility model has the advantages of simple structure, the metallographic specimen reliable clamping during the specimen grinding.
Description
Technical field
The utility model relates to a kind of metallographic specimen anchor clamps that grind.
Background technology
Because metal lographic examination result's accuracy depends on the height of the preparation quality of metallographic specimen to a great extent.For a long time, the preparation of metallographic specimen is also just become the importance of metallographic professional research.Preparation difficulty especially less to profile, thin metallographic specimen is bigger, and bonding insecure, and metallographic specimen is often dished out at a high speed in the process of grinding.Have only now to inlay to grind again behind the metallographic specimen to reach the preparation requirement, can only satisfy the normal temperature metal lographic examination,, just can not meet the demands when sample undergoes phase transition under different temperatures when observing but inlay metallographic specimen by pointing machine.
Summary of the invention
Bonding insecure in order to overcome the existing metallographic specimen anchor clamps that grind, the deficiency that metallographic specimen is dished out in grinding the process of metallographic specimen, the utility model provide a kind of clip firm grind the metallographic specimen anchor clamps.
The utility model is to utilize ferrous materials to have the characteristic of magnetic, with permanent magnet metallographic specimen is held, and in the groove or hole of the anchor clamps of packing into, the lower surface of metallographic specimen exposes the hole, prevents that metallographic specimen from falling down in the process of grinding or dished out at a high speed.
The utility model comprises clamping fixture seat, clip spare, it is characterized in that: said clamping fixture seat is the derby that there is tapped through hole at the middle part, the diameter of tapped through hole is greater than the diameter of the metallographic specimen that is ground, general big 2 millimeters, said clip spare is that the upper end has the groove and the outside to have externally threaded permanent magnet, and permanent magnet is screwed in the tapped through hole.
The utility model also can be taked such structure, it comprises clamping fixture seat, clip spare, it is characterized in that: said clamping fixture seat is the derby that there is tapped through hole at the middle part, the diameter of tapped through hole is greater than the diameter of the metallographic specimen that is ground, general big 2 millimeters, said clip spare is a fluting flush end cylinder screw, and this screw is screwed in the tapped through hole, the lower end sorption permanent magnet of double-screw bolt, the diameter of permanent magnet is less than tapped through hole.
During use, metallographic specimen is inhaled below permanent magnet, regulated the height of permanent magnet, the tapped through hole that makes the lower surface of metallographic specimen expose clamping fixture seat gets final product.The utility model holds metallographic specimen with permanent magnet, and in the tapped through hole of the anchor clamps of packing into, has overcome existing bonding insecure, the metallographic specimen deficiency that quilt is dished out in the process of grinding of metallographic specimen anchor clamps that grinds.

Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in detail.
Embodiment of the present utility model sees Fig. 1, it has clamping fixture seat 1, clip spare, it is characterized in that: said clamping fixture seat 1 is the derby that there is tapped through hole 2 at the middle part, the diameter of tapped through hole 2 is greater than the diameter of the sample that is ground, said clip spare is that the upper end has the groove outside to have externally threaded permanent magnet 3, and permanent magnet 3 is screwed in the tapped through hole 2.Metallographic specimen 4 is inhaled the lower end at permanent magnet 3.
The clamping fixture seat 1 of present embodiment is that diameter is 18 millimeters, high 15 millimeters right cylinder, and the diameter of tapped through hole 2 is the M8 millimeter, and the diameter of permanent magnet 3 is the M8 millimeter, and the diameter of metallographic specimen 4 is 6 millimeters, and is high 2 millimeters.
Embodiment two of the present utility model sees Fig. 2, it has clamping fixture seat 1, clip spare, it is characterized in that: said clamping fixture seat 1 is the metallographic piece that there is tapped through hole 2 at the middle part, the diameter of tapped through hole 2 is greater than the diameter of the metallographic specimen 4 that is ground, said clip spare is a fluting flush end cylinder screw 5, this screw is screwed in the tapped through hole 2, fluting flush end cylinder screw 5 sorption permanent magnets 6, and metallographic specimen 4 is inhaled below permanent magnet 6.
The diameter of the fluting flush end cylinder screw 5 of present embodiment is the M8 millimeter, and the diameter of permanent magnet 6 is 7 millimeters, and is high 3 millimeters, and other structure is identical with embodiment one.
Loosening in order to prevent in the process of grinding permanent magnet 3 or fluting flush end cylinder screw 5, can make a call to a screw in the side of clamping fixture seat 1, at this screw one spiral shell is installed and is decided screw.
