Abstract
The utility model provides a small jack structure, solves the problems in the prior art, and is high in supporting stability of a turbine sample. The small jack structure comprises a base, wherein a flange is arranged at the bottom of a body of the base; the base is hollow; and an internal thread section is arranged on a hollow part in the base. The small jack structure is characterized in that a trumpet type port is formed on the upper part of the body of the base; and a small port bottom of the trumpet type port is connected with the top of the internal thread section.
Description
Technical field
The utility model relates to the support device of turbine exemplar, is specially the small-size jack structure.
Background technique
In turbine exemplar mapping process, because the shape of turbine exemplar is irregular mostly, so can not steadily place, fixedly exemplar of auxiliary device need to be arranged.Existing adopt a kind of small-size jack, as shown in Figure 1, if need the exemplar of mapping that the screw suitable with jack 1 upper end oral area 2 arranged, carry out surveying-drawing work on the jack with regard to a bolt exemplar being fixed on; If have and jack 1 upper end oral area 2 corresponding thread spindles on the exemplar that needs to survey and draw, just directly thread spindle is screwed in, fix exemplar and carry out surveying-drawing work.But the problem that this structure exists is that exemplar directly is installed on jack by the thread spindle of bolt or exemplar, workpiece places the top of jack, and its center of gravity is higher, less stable, especially support with this jack for rectangular exemplar, its stability is relatively poor especially.
Summary of the invention
For above-mentioned situation, the utility model provides the small-size jack structure, can solve the problem that present technology exists, and stronger with its stability that supports the turbine exemplar.
Its technological scheme is such, it comprises base, bottom at the body of described base is provided with flange, the inside of described base is hollow, the described middle vacancy of described base inside is provided with internal thread segment, it is characterized in that: the top at the body of described base has the horn shape port, and the top with described internal thread segment at the bottom of the portlet of described horn shape port joins.
After the utility model adopts said structure, top at the body of base has the horn shape port, top with internal thread segment at the bottom of the portlet of horn shape port joins, and the inside of base was hollow originally, the horn shape port is connected with internal thread segment like this, and internal thread segment is arranged in the hypomere at base inner hollow place, when the thread spindle of exemplar by bolt or exemplar directly is installed on the internal thread segment of base, the center of gravity that equals exemplar has moved down compared to prior art, and the large end of horn shape port up, also be more convenient for exemplar location, therefore, the utility model has solved the problem of prior art, supports the turbine exemplar with it, especially support long strip turbine exemplar, its stability is stronger.
