Abstract
The invention provides a horizontal positioning method of an automatic grinding wheel sample grinder sample, which aims the center of the lower surface of the sample at a hemispherical bulge arranged at the center of a sample placing table, adjusts a positioning surface to a horizontal position, enables the positioning surface to be contacted with the upper surface of the sample, enables the upper surface of the sample to be attached to the positioning surface under the action of the hemispherical bulge, enables the positioning surface to be lifted away from the upper surface of the sample after the sample is clamped by a hydraulic clamp, and enables the surface to be processed of the sample to be stabilized at a position parallel to a grinding motion surface of a grinding wheel. The invention can quickly adjust the sample processing surface to be parallel to the grinding motion surface of the grinding wheel, realizes compensation and correction of the sample with poor parallelism of the upper surface and the lower surface, ensures the sample processing quality, enlarges the use range of the sample processed by the grinding wheel sample grinding machine, improves the use efficiency of the automatic sample grinding machine, shortens the sample analysis period and meets the production requirement.
Description
Technical field
The invention belongs to material tests technical field, particularly a kind of horizontal location modification method of automatic grinding wheel specimen grinding machine sample.
Background technology
GBT20066-2006 steel and iron chemical constituents determination by specified in more detail in the sampling of sample and method for making sample steel and iron chemical constituents determination principle, the method with sample sample preparation.Along with the development of automatic technology, the maturation of grind away technology and the extensive use of Automatic Grinding Prototype make grind away operation safer, quick automatically.
Traditional Automatic Grinding Prototype generally adopts the location technology of Pneumatic pressure rod-type to determine grinding position and the degree of depth of sample, this kind of necessary level of matching requirements sample upper and lower surface, otherwise will there is sample grinding lateral deviation, not reach examination criteria requirement, can not meet need of production.And in real sample machining Practice, the upper and lower surface of sample is not parallel is a kind of common phenomenon, result causes the repeatedly sample preparation of having to, repeat operation does not reach even all the time and requires and can not use the situation of Automatic Grinding Prototype at all, thereby greatly reduces the operating efficiency of Automatic Grinding Prototype.
Summary of the invention
The object of the present invention is to provide a kind of simplely, convenient use, can be adjusted to sample machined surface parallelly with wheel grinding moving surface fast, avoids repetition sample preparation, guarantees the automatic grinding wheel specimen grinding machine sample levels positioning correction method of sample quality.
For this reason, the solution that the present invention takes is:
An automatic grinding wheel specimen grinding machine sample levels localization method, is characterized in that, concrete grammar and step are:
1, at sample mounting table center, a hemispherical projections is set, will after the aligning hemispherical projections of sample lower surface center, be placed on sample mounting table;
2, the position parallel with grind away wheel grinding moving surface calibrated and be fixed on to the locating surface of depression bar lower end, location;
3, start pneumatic linear actuator, making to locate depression bar moves downward to an end in contact of the location locating surface of depression bar lower end and the upper surface perk of sample, after continuing to exert pressure, the lower surface of sample is under the effect of hemispherical projections fulcrum, to make sample upper surface and locating surface fit completely, sample upper surface is also in the position parallel with grind away wheel grinding moving surface;
4, start the hydraulically operated fixture of sample both sides, hydraulically operated fixture is by the slightly sample clamping of arc of two ends;
5, lifting backstay, is lifted away from sample upper surface by location depression bar, and the sample upper surface of hydraulically operated fixture clamping is that to be processed of sample will be stabilized in and wheel grinding moving surface parallel position, can carry out grind away operation.
The radius of described hemispherical projections is 1.8-2.2mm.
Beneficial effect of the present invention is:
The present invention makes full use of the circular point action of hemispherical projections, rapidly sample machined surface is adjusted to parallel with wheel grinding moving surface, realization compensates and corrects the bad sample of the upper and lower surface depth of parallelism, guaranteed the crudy of sample, expanded the scope of application of automatic grinding wheel specimen grinding machine processed sample, improved the service efficiency of Automatic Grinding Prototype, and because of a sample preparation rate raising, and even avoid repeatedly sample preparation, repeat the underproof phenomenon of operation sample preparation, shorten the sample analysis cycle, guaranteed the needs of producing.
Accompanying drawing explanation
Accompanying drawing is automatic grinding wheel specimen grinding machine sample levels positioner schematic diagram.
In figure: backstay 1, locating surface 2, sample 3, hydraulically operated fixture 4, hemispherical projections 5, sample mounting table 6.
The specific embodiment
Accompanying drawing is automatic grinding wheel specimen grinding machine sample levels positioner schematic diagram, and from accompanying drawing, positioner main body used in the present invention is also unchanged, still backstay 1, locating surface 2, hydraulically operated fixture 4 and sample mounting table 6, is consisted of.Difference is on sample mounting table 6, to have installed a hemispherical projections 5.
The concrete steps of the automatic grinding wheel specimen grinding machine sample levels of the present invention localization method are:
1,, in a hemispherical projections 5 that radius is 2mm of the center of sample mounting table 6 welding, will after the lower surface center aligning hemispherical projections 5 of sample 3, be placed on sample mounting table 6.
2, utilize level meter that locating surface 2 schools of depression bar 1 lower end, location are also fixing to level, make locating surface 2 in the position parallel with grind away wheel grinding moving surface.
3, start the pneumatic linear actuator being connected with location depression bar 1, making to locate depression bar 1 moves downward to the locating surface 2 of lower end and an end in contact of sample 3 upper surface perks, after continuing to exert pressure, sample 3 lower surfaces are under the effect of hemispherical projections 5 fulcrums, to make sample 3 upper surfaces and locating surface 2 fit completely, sample 1 upper surface is in the position parallel with grind away wheel grinding moving surface.
4, start the hydraulically operated fixture 4 of sample both sides, hydraulically operated fixture 4 is by slightly sample 3 clampings of arc of two ends.
5, adjust pneumatic linear actuator lifting location depression bar 1, location depression bar 1 is lifted away to the upper surface of sample 3, the face to be processed of the sample 3 of hydraulically operated fixture 4 clampings is stabilized in and wheel grinding moving surface parallel position, can carry out grind away operation.
