Abstract
The utility model relates to an expansion device in a machine tool fixture. The expansion device in the machine tool fixture is characterized by comprising a core shaft and a bolt, wherein a hexagonal prism is arranged at the end part of the core shaft; a circular platform hole, which is big outside and small inside, is formed in the axis direction of the hexagonal prism; an internal screw thread I is arranged at the inner end of the circular platform hole; a straight line shaped opening parallel to the axis is formed at the three spaced surfaces of one hexagonal prism; the straight line shaped opening is communicated with the inside circular platform hole; the end part of the circular platform hole is the end surface of the hexagonal prism; one end of the bolt is an external screw thread which is fastened into the internal screw thread I; and the other end of the bolt is a circular platform column matching with the circular platform hole of the hexagonal prism. The expansion device in the machine tool fixture, provided by the utility model, has compact structure; and according to the utility model, the clamping space of the work fixture is saved, the working time needed by the clamping is reduced and the production efficiency is increased.
Description
Technical field
The utility model relates to the swelling device in a kind of jig, is used for can using separately or be installed in the jig from the swelling device of tube shape component internal fixation part.
Background technology
For fixing tube shape component, tend to externally tame V-block or wear the pin rod set clip in inside tight, so not only the space size to anchor clamps has certain requirement, also wasting the regular hour aspect the loading and unloading part, influences operating efficiency.
Summary of the invention
The technical problem that the utility model will solve provides the swelling device in a kind of jig, and this apparatus structure is compact, promptly saves the clamping space of frock clamp, reduces clamping used working time again, enhances productivity.
For overcoming the above problems, the concrete technical scheme of the utility model is following: the swelling device in a kind of jig is characterized in that: be made up of mandrel and screw; The end of mandrel is provided with six prisms; Six prismatic axis directions are provided with the little round platform hole of outer imperial palace, and the inner in round platform hole is provided with the internal thread I, are provided with the 1-shaped open with the parallel axes setting at six prismatic three faces separately; 1-shaped open communicates with inner round platform hole, and the end of 1-shaped open is the end face of six prisms; One end of screw is external screw thread and is screwed in the internal thread I that the other end of screw is the round platform post that cooperates with six prismatic round platform holes.
The excircle of described mandrel is a frustum cone structure.
The other end of described mandrel is provided with the internal thread II.
Swelling device in this jig adopts the 1-shaped open structure, utilizes the frustum cone structure of the end of screw, makes the 1-shaped open distending, thereby the tube shape component swelling is fixed.
The excircle of mandrel is a frustum cone structure, can make things convenient on its anchor clamps that are fixed on lathe; The other end is provided with the internal thread II, so that use separately, is fixed on the ancillary equipment.
Description of drawings
Fig. 1 is the structural representation of the swelling device in the jig.
Fig. 2 puts into cutaway view for the swelling device in the jig.
The specific embodiment
As depicted in figs. 1 and 2, the swelling device in a kind of jig is made up of mandrel 1 and screw 2; The end of mandrel 1 is provided with six prismatic 3; Six prismatic 3 axis direction be provided with the little round platform hole of outer imperial palace, the inner in round platform hole is provided with internal thread I 4, three faces separately six prismatic 3 are provided with the 1-shaped open 5 with the parallel axes setting; 1-shaped open 5 communicates with inner round platform hole, and the end of 1-shaped open 5 is six prismatic 3 end face; One end of screw 2 is external screw thread and is screwed in the internal thread I 4 that the other end of screw 2 is the round platform post that cooperates with the round platform hole of six prisms 3.
The excircle of described mandrel 1 is a frustum cone structure.
The other end of described mandrel 1 is provided with internal thread II 6.
Earlier that mandrel 1 is fixing during use, then tube-type part to be processed is enclosed within on the outer surface of six prisms 3, screw 2 is screwed in the mandrel 1, make 1-shaped open 5 distendings, thereby, reach the fixing effect of part tube-type part to be processed swelling internally.
