Abstract
The invention provides a small jack structure which is capable of resolving problems in the prior art and has high stability in supporting a turbine sample piece. The small jack structure comprises a base, a flange is disposed at the bottom of a base body, the base is hollow, and an internal thread section is arranged at the hollow position inside the base. The small jack structure is characterized in that a trumpet type port is formed in the upper portion of the base body, and the bottom of a small port of the trumpet type port is connected with the top end of the internal thread section.
Description
?
Technical field
The present invention relates to the support device of turbine exemplar, be specially a kind of 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.A kind of small-size jack of existing employing as shown in Figure 1, if need the exemplar of mapping that the screw suitable with jack 1 upper end oral area 2 arranged, carries out surveying-drawing work with regard to a bolt, exemplar being fixed on jack; If have and the jack 1 corresponding thread spindle of upper end oral area 2 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 is placed in 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 invention provides a kind of 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 present invention 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 when 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 invention solves the problem of prior art, support the turbine exemplar with it, especially support long strip turbine exemplar, its stability is stronger.
