The technical scheme that its technical matters that solves the utility model adopts is: xsect sample bonding fixture, comprise base, be relatively arranged on the pressure head on the base and the latch mechanism of sample cavity, adjusting pressure head and sample cavity spacing, be provided with mould, described sample cavity is arranged on the mould; Described pressure head and mould are by the solid replaceable stand-alone assembly of the structure that removably connects, and pressure head one of them links to each other with latch mechanism and is arranged on the base by latch mechanism at least with mould.
Further, described latch mechanism is a check lock lever, is provided with locking spring between described check lock lever and the base.
Further, described check lock lever is the silk that cooperates with whorl of base.
Further, the described structure that removably connects is a connected structure.
Further, described pressure head links to each other with check lock lever, and the connected structure that connects pressure head and check lock lever comprises the jack that is arranged on the check lock lever termination and be arranged on the latch of pressure head afterbody, and the axis of described jack is with the parallel axes of check lock lever or overlap; Described mould is fixed in base, and the connected structure that connects mould and base comprises the dovetail groove that is arranged on the base and be arranged on the connected structure of the dovetail formation of mould bottom surface that described dovetail groove is axially axially vertical with jack.
Further, described locking spring is to be arranged at link to each other with pressure head compression spring between an end and the base of check lock lever.
As a kind of preferred, described base is the block structure that is provided with groove; Described check lock lever matches respectively at relative groove two side with mould, and described mould, pressure head are relative is positioned at groove.
In order to adapt to various restriction and requirement, necessarily require xsect sample bonding fixture to have flexible adaptability and certain versatility.The utility model is by all being set to removable stand-alone assembly with pressure head and mould, by replacing satisfy the demands pressure head and sample cavity, cooperate the preparation of respective sample targetedly, guarantee the preparation of each class standard under the different demand conditions, non-standard xsect sample, widened the selectable range of material analysis study sample.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, shown in Figure 3, xsect sample bonding fixture of the present utility model, comprise base 1, be relatively arranged on pressure head 2 on the base 1 and sample cavity 6, regulate the latch mechanism of pressure head 2 and sample cavity 6 spacings, be provided with mould 3, described sample cavity 6 is arranged on the mould 3; Described pressure head 2 and mould 3 are by the solid replaceable stand-alone assembly of the structure that removably connects, and pressure head 2 one of them links to each other with latch mechanism and is arranged on the base 1 by latch mechanism at least with mould 3.
In order to adapt to various restriction and requirement, necessarily require xsect sample bonding fixture to have flexible adaptability and certain versatility.The utility model is by all being set to removable stand-alone assembly with pressure head 2 and mould 3, by replacing satisfy the demands pressure head 2 and sample cavity 6, cooperate the preparation of respective sample targetedly, guarantee the preparation of each class standard under the different demand conditions, non-standard xsect sample, widened the selectable range of material analysis sample.
Above-mentioned latch mechanism is that spacing compresses to guarantee sample cavity 6 interior each sample between mould 3 and the pressure head 2 in order to adjust, the mechanism of lasting snap-in force is provided simultaneously, it can be a mechanism arbitrarily, and above-mentioned pressure head 2, mould 3 can both equal scalable also can only be regulated one.Prop up as the scissors-type by similar scissors-type lifting jack and to be configured to latch mechanism, the scissors-type support is fixed in base 1 by its jointed shaft, and pressure head 2 and mould 3 are separately fixed at scissors-type support two ends and are slidingly matched with base 1.
For simplified structure, guarantee the accuracy of location, best, described latch mechanism is a check lock lever, is provided with locking spring between described check lock lever and the base 1.
Further, for convenience sample is put into sample cavity 6, strengthen locking effect, described check lock lever is and base 1 threaded-fit screw rod 8.At this moment, coupling mechanism force mainly contains threaded engagement and provides, and locking spring then can be eliminated the tolerance clearance of threaded engagement, the tolerance clearance that elimination causes owing to thermal expansivity difference in the solidification process.Check lock lever can also adopt the forms of two joints by being threaded in addition, but this formal operations inconvenience, range of adjustment are little.
The above-mentioned structure that removably connects can adopt screw thread or screw connection etc., operation for convenience, and the described structure that removably connects is a connected structure.Concrete, described pressure head 2 links to each other with check lock lever, and the connected structure that connects pressure head 2 and check lock lever comprises the jack that is arranged on the check lock lever termination and be arranged on the latch 5 of pressure head 2 afterbodys, and the axis of described jack is with the parallel axes of check lock lever or overlap; Described mould 3 is fixed in base 1, and the connected structure that connects mould 3 and base 1 comprises the dovetail groove that is arranged on the base 1 and be arranged on the connected structure of dovetail 7 formations of mould 3 bottom surfaces that described dovetail groove is axially axially vertical with jack.Dovetail groove axially with the axially vertical direction that guarantees coupling mechanism force of jack.Because check lock lever is screw mandrel 8, the connected structure that jack and latch 5 are formed has made things convenient for pressure head 2 has been rotated, and has guaranteed cooperating between pressure head 2 and the mould 3, especially when pressure head 2 is non-revolved body.
Further, described locking spring is to be arranged at link to each other with pressure head 2 compression spring 9 between an end and the base 1 of check lock lever.Compare with the extension spring that is arranged between the check lock lever other end and the base 1, need not to be provided with the structure of respective fixation spring, only compression spring 9 need be enclosed within on the screw mandrel 8 and get final product, be provided with more convenient, simple.
