Abstract
The utility model discloses a metallographic specimen clamp, which comprises an upper clamping board, a lower clamping board, a left stud and a right stud, wherein the left stud and the right stud are connected between the upper clamping board and the lower clamping board, and the lower portion of the right stud is screwed in a thread hole installed on the right portion of the lower clamping board. The right portion of the upper clamping board is hinged to the upper end of the right stud, and a clamping groove is arranged on the left end face of the upper clamping board. The lower end of the left stud is hinged to the left portion of the upper clamping board, a left nut is screwed on the upper portion of the left stud, the left stud rotates towards the upper side and then is clamped into the clamping groove arranged on the left end face of the upper clamping board, and the left nut is screwed tight to be pressed on the upper surface of the upper clamping board. The metallographic specimen clamp is simple in structure, reasonable in design, capable of meeting requirements of metallographic inspection and use requirements of enterprises and convenient for operation of operators.
Description
Technical field:
The utility model relates generally to a kind of clamping device of sample, relates in particular to a kind of metallographic specimen anchor clamps.
Background technology:
Metal lographic examination is a kind of method of observation metal material microstructure of classics, is still the conventional means of experimental material so far, and it is to the snotter in the sample, and the structure of phase is analyzed.For material is carried out metal lographic examination, need carry out specimen preparation in advance to sample, and the having relatively high expectations of metallographic specimen preparation.After metal material is sheared, owing to process the range of influence in the shear history, so the first step of metallographic specimen preparation will be cut generation processing range of influence in the excision shear history exactly through cold cut; To carry out grinding and polishing to the metallographic cross section then, avoid because coarse polishing produces indenture and scuffing, as far as possible can be to guarantee to be detected as smooth as the minute surface.
Usually the detection faces of metallographic specimen all is the cross section, and the thickness of sample is the 0.3-3.0 millimeter basically.In carrying out the metallographic specimen testing process,, carry out batch detection usually: be about to detect together after a collection of model clamps with special fixtures for improving detection efficiency and solving manual work and cost.
The anchor clamps of detection metallographic specimen commonly used can satisfy the requirement of metal lographic examination at present, but need two hands to work simultaneously, and operation is very inconvenient.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of convenient detection and metallographic specimen anchor clamps simple in structure to be provided.
The utility model is realized through following technical scheme:
A kind of metallographic specimen anchor clamps include upper and lower clamping plate and are connected in the left and right double-screw bolt between the upper and lower clamping plate, it is characterized in that: right double-screw bolt bottom spinning is in the threaded hole of lower plate right part; The train wheel bridge right part is hinged on the upper end of right double-screw bolt, and train wheel bridge has draw-in groove on the left side; Double-screw bolt lower end, a left side is hinged on the left part of train wheel bridge, and left double-screw bolt top is installed with left nut, and left double-screw bolt snaps in the draw-in groove on the train wheel bridge left side after upside rotates, and the left nut of screwing makes on its upper surface that is pressed on train wheel bridge.
A kind of metallographic specimen anchor clamps is characterized in that: have threaded hole on the said train wheel bridge, be installed with compression leg in the threaded hole, stretch out outside the train wheel bridge compression leg bottom, and the compression leg bottom is fixedly connected with pressing plate.
A kind of metallographic specimen anchor clamps is characterized in that: the position that is positioned at the lower plate downside on the said left double-screw bolt is installed with right nut.
During operation, sample is placed on the lower plate, rotates train wheel bridge and make its top that is pressed on sample, rotate left double-screw bolt again and make it snap in the draw-in groove on the train wheel bridge left side, the left and right nut of screwing successively makes on its outside surface that is pressed in upper and lower clamping plate respectively.At last, the compression leg of screwing is pressed onto on the sample pressing plate.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, can satisfy the requirement of metal lographic examination, is convenient to staff's operation, satisfied the user demand of enterprise.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
