Description
Technical Field
The utility model relates to a metallographic fixture field specifically is a prefabricated anchor clamps for metallographic specimen.
Background
The metallographic phase refers to the chemical components of metal or alloy and the physical state and the chemical state of various components in the alloy, the metallographic phase is observed under a microscope, when the metallographic phase is tested, the steps of sample embedding, coarse grinding, fine grinding, polishing, corrosion and the like need to be carried out, the steps need to utilize a clamp to clamp the metallographic phase sample, in the metallographic phase polishing sample preparation clamp with the application number of 202120034830.1, a small pipeline sample or a bar rod is fixed through a positioning bolt, a handle is held by a hand or a lengthened handle is placed on a polishing machine to carry out manual polishing and grinding on the sample, as the positioning bolt of the device directly acts on the outer surface of the pipeline sample to clamp, and the upper end of the outer surface of the pipeline sample is shielded by the lower end of a clamp sleeve, the outer surface at the upper end of the pipeline sample cannot be polished, the positioning bolt needs to be detached, the polishing end part of the pipeline sample is inserted into the clamp sleeve, and the positioning bolt is locked to carry out polishing, so that the metallographic phase polishing is very inconvenient.
In view of this, we propose a prefabricated jig for metallographic specimen to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model provides a prefabricated anchor clamps for metallographic specimen makes splint support tightly at pipeline sample internal surface through moving down of fixed holder, realizes the polishing of pipeline sample surface.
The utility model provides a following technical scheme: the utility model provides a prefabricated anchor clamps for metallographic specimen, includes the prefabricated anchor clamps body, and the prefabricated anchor clamps body includes the sample roof, sample roof lower extreme is fixed with fixed sleeve, sample roof threaded connection has the screw rod that runs through fixed sleeve, the screw rod lower extreme is fixed with the fixation clamp seat, sliding connection has splint in the fixed sleeve, splint and fixation clamp seat surface contact, the fixed sleeve runs through and is equipped with the jack, fixed sleeve's upper end internal surface sets up planar structure's clamping part.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an anchor clamps move down through the fixation clamp seat and make splint remove centre gripping metallographic tube sample internal surface, have avoided centre gripping metallographic tube sample surface to cause to shield the problem that the position polishing can not arrive, and through shifting up of fixation clamp seat, realize the bar-shaped sample centre gripping of metallography between fixing base and clamping part to can carry out the centre gripping of pipeline sample and bar-shaped sample.
