Abstract
The utility model discloses a clamp capable of grinding metallographic specimen thickness accurately and aims to solve the problems that the cost is high, the manual grinding is toilsome and inaccurate in the conventionally applied accurate positioning automatic grinding and polishing machines. The clamp capable of grinding metallographic specimen thickness accurately comprises a cup-shaped base, a positioning tray, retaining screws and a jack screw, wherein the positioning tray is horizontally placed in the cup-shaped base; the periphery of the positioning tray and the inner wall of the cup-shaped base are in close fit; a column-shaped hole is formed in the center at the bottom of the cup-shaped base; perpendicular scales are formed on the side wall of the column-shaped hole; the jack screw penetrates through the bottom of the column-shaped hole and is propped against the bottom of the positioning tray; the retaining screws penetrate through the side wall of the cup-shaped base and are used for fixing a metallographic specimen placed on the positioning tray. The clamp capable of grinding metallographic specimen thickness accurately has the advantages that thickness of a to be grinded sample can be accurately adjusted and positioned through the scales on the inner wall of the column-shaped hole, the thickness positioning is accurate, the grinding accuracy can be guaranteed, the structure is simple, the operation is convenient, the cost is low and the clamp can be used for manual and automatic grinding.
Description
Technical field
The utility model relates to a kind of fixture that can accurately grind metallographic specimen thickness.
Background technology
Metallographic examination is one of means of check analysis material, is intended to disclose the heterogeneous microstructure of material.Carry out metallographic examination, just must preparation can be used for the sample that microscopic observation is checked, i.e. metallographic specimen.Conventionally, metallographic specimen preparation will be passed through following step: sample → inlay → polishing → polishing → corrosion.Wherein grinding and polishing process is ground to different thickness positions needing that in some cases metallographic is inlayed to sample, to analyze metallographic structure, the texture etc. at the different thicknesss of slab of ferrous materials position, or analyzes the situation of inoperative component ad-hoc location.This pinpoint grinding method is generally realized in the following manner: 1, use precision positioning automatic grinding and polishing machine, carry out precision positioning and grind, set after suitable stock removal by equipment, automatic grinding, until grind to suitable thickness.These equipment are often expensive.2, grind by hand, grinds and on one side measure specimen height, by initial sample height, with to grind middle measuring height poor, definite thickness having ground, until grind to suitable thickness.This mode is consuming time longer, measures loaded down with trivial detailsly, and thickness error is larger, and hand-held sample grinds and easily causes specimen surface injustice.
Summary of the invention
The purpose of this utility model is to overcome prior art defect, and a kind of fixture that can accurately grind metallographic specimen thickness is provided.
The technical solution of the utility model is achieved in that the fixture that can accurately grind metallographic specimen thickness, formed by cup-shaped pedestal, location tray, fixed screw, jacking screw rod, location tray lies in a horizontal plane in cup-shaped pedestal and periphery and cup-shaped base internal wall closely cooperate, cup-shaped base bottom center has cylindrical hole, on cylindrical hole sidewall, there is vertical scale, jacking screw rod passes cylindrical hole bottom and withstands location tray and try to get to the heart of a matter, and fixed screw is fixed through after cup-shaped pedestal sidewall the metallographic specimen being placed in location tray.
Further, cup-shaped pedestal and location tray xsect are circle.
Further, 120 °, three fixed screw intervals are respectively through cup-shaped pedestal xsect sidewall.
The utility model is inlayed sample by metallographic and is directly put in the location tray of cup-shaped pedestal, has regulated after height by jacking screw rod, fixedly grinds with fixed screw, easy to operate; Can locate the sample thickness that need to grind by accurate adjustment by cylindrical hole inwall scale, thickness registration, has ensured the accurate of grinding, and simple in structure, and cost is low, can be used for manually and automatic grinding.
Brief description of the drawings
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure vertical view.
In figure, 1-cup-shaped pedestal; 2-location tray; 3-fixed screw; 4-cylindrical hole; 5-jacking screw rod.
Embodiment
Be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in Fig. 2, can accurately grind the fixture of metallographic specimen thickness, by cup-shaped pedestal 1, location tray 2, fixed screw 3, jacking screw rod 5 forms, location tray 2 lies in a horizontal plane in cup-shaped pedestal 1 and periphery and cup-shaped pedestal 1 inwall closely cooperate, cup-shaped pedestal 1 bottom centre has cylindrical hole 4, on cylindrical hole 4 sidewalls, there is vertical scale, jacking screw rod 5 passes cylindrical hole 4 bottoms and withstands location tray 2 and try to get to the heart of a matter, fixed screw 3 is fixed through after cup-shaped pedestal 1 sidewall the metallographic specimen being placed in location tray 2, cup-shaped pedestal 1 and location tray 2 xsects are circle, 120 °, three fixed screw 3 intervals are respectively through cup-shaped pedestal 1 xsect sidewall.
Operation steps:
1, the metallographic specimen of having inlayed is put into cup-shaped pedestal 1, regulate location tray 2 height, make metallographic specimen upper surface concordant with cup-shaped pedestal 1 upper surface, record the cylindrical hole 4 inwall scales that now jacking screw rod 5 ends are corresponding, deduct by this position scale the thickness that metallographic specimen need to grind, be target scale, regulate jacking screw rod 5 to target scale;
2, with the fixing metallographic specimen of three fixed screws 3, sample cannot be moved;
3, the fixture upset of placing metallographic specimen is carried out to hand-ground, or install to sample grinding machine automatic grinding, be worn away completely until exceed the sample thickness of cup-shaped pedestal 1 upper surface;
4, pass through successively varigrained sand paper from coarse to fine and the grinding and polishing of polishing cloth, be prepared into the minute surface sample that can carry out metallographic observation.
The utility model regulates the height of metallographic specimen with jacking screw rod 5 and cylindrical hole 4 inwall scales, determine the sample thickness that need to grind by metallographic specimen surface is concordant with cup-shaped pedestal 1 surface with the difference in height that exceeds two positions of base-plates surface, its precision can reach 0.1mm.Cup-shaped pedestal 1 uses high abrasion resisting material, therefore in process of lapping, is difficult to be worn, thereby makes material can accurately grind the thickness that exceeds base-plates surface, reaches accurate location object.
