Description
Technical field
The utility model relates to machine tooling tooling fields, and in particular to a kind of inner support jig.
Background technique
In machine tooling operation, the workpiece that needs first to clamp or have good positioning just can be carried out processing.Currently, most applications are all adopted
The workpiece for being clamped or being positioned with self-centering chuck, but had is not available self-centering chuck and is positioned, such as hole within needing
Positioning, wall thickness is thin and the longer cast workpiece of length, is easy to appear machining deformation using self-centering chuck.Therefore it needs to design one
Kind processes the tooling or jig of such workpiece, guarantees processing quality and processing concentricity.
Summary of the invention
The purpose of this utility model is to provide a kind of inner support jigs, carry out positioning using the jig and assemble certifiable cast
The processing quality and processing concentricity of workpiece.
The purpose of this utility model is achieved through the following technical solutions: a kind of inner support jig, including inner support seat ontology,
Inner support pull rod and at least one set of tensioner group trap, the inner support seat ontology are provided with axis hole along axial direction, and the inner support pull rod is inserted into
In axis hole, the inner support seat ontology includes integrally formed connecting flange and cylindrical sleeve, and the tensioner group trap housing is in tubular
It puts on, tensioner group trap includes that an inner support taper transitions set and two deformable inner expanding sleeves, inner support taper transitions set are located at
Between two deformable inner expanding sleeves, and inner support taper transitions put on the backing pin being provided with for limiting deformable inner expanding sleeve, described
The sliding slot being slidably matched with backing pin is machined on deformable inner expanding sleeve, the inner support pull rod is machined with close to one end of connecting flange
Screw thread, the other end are provided with the pull head for tensing deformable inner expanding sleeve.
Further, the port at the deformable inner expanding sleeve both ends is the horn mouth inwardly collapsed, the inner support taper
The both ends of transition sleeve form and the matched ring cone of horn mouth.
Further, the side ring surface of the pull head be with the matched conical surface of horn mouth, the cylindrical sleeve and connecting flange at
One end anchor ring of type be and the matched conical surface of horn mouth.
Further, the backing pin being in sliding fit with the sliding chute is provided on the conical surface of the pull head and the conical surface of cylindrical sleeve.
The utility model squeezes deformable inner expanding sleeve, realizes the radial support of deformable inner expanding sleeve by tensing inner support pull rod
Greatly, the inner hole of stretching cast workpiece, in order to which the outer shape to cast workpiece is processed, to guarantee to process rear constant
Shape, concentricity are high.

Specific embodiment
As shown in Figure 1, inner support jig provided in this embodiment includes inner support seat ontology 2, inner support pull rod 1 and one group of tensioner group
Trap, the inner support seat ontology 2 are provided with axis hole along axial direction, and the inner support pull rod 1 is inserted into the axis hole, the inner support seat ontology
2 include integrally formed connecting flange 21 and cylindrical sleeve 22, and the tensioner group trap housing specifically, rises on cylindrical sleeve 22
Tight integration set includes an inner support taper transitions set 3 and two deformable inner expanding sleeves 4, and inner support taper transitions set 3 is located at two
Between deformable inner expanding sleeve 4, in the present embodiment, deformable inner expanding sleeve 4 is made of thermosetting plastics, and deformable inner expanding sleeve 4
The port at both ends is the horn mouth 23 inwardly collapsed, in order to increase the matching of inner support taper transitions set 3 with deformable inner expanding sleeve 4
Degree, the both ends of inner support taper transitions set 3 form with the matched ring cone of horn mouth 23 so that deformable inner expanding sleeve 4
Port can along inner support taper transitions cover 3 ring cones tapered surface move.The inner support pull rod 1 is close to the one of connecting flange 21
End is threaded, and the other end is provided with the pull head 11 for tensing deformable inner expanding sleeve 4.
The disengaging cast workpiece 6 of deformable inner expanding sleeve 4 in order to prevent, the inner support taper transitions, which cover to be provided on 3, to be used for
The backing pin 5 of deformable inner expanding sleeve 4 is limited, at least one item being slidably matched with backing pin 5 is machined on the deformable inner expanding sleeve 4
Shape sliding slot.The side ring surface of the pull head 11 be with the matched conical surface 12 of horn mouth 23, the cylindrical sleeve 22 and connecting flange 21 at
One end anchor ring of type be with the matched conical surface 12 of horn mouth 23, on the conical surface 12 of the pull head 11 and the conical surface 12 of cylindrical sleeve 22
It is provided with the backing pin 5 being in sliding fit with the sliding chute.
The working principle of the utility model is: this jig is mounted on lathe by connecting flange 21, by rotation
The thread segment for supportting pull rod 1 makes pull head 11 squeeze the deformable inner expanding sleeve 4 of end, by the effect of inner support taper transitions set 3, squeezes
Another deformable inner expanding sleeve 4 is pressed, thus keep the radial support of deformable inner expanding sleeve 4 big, it is final to stablize stretching cast tooling 6.In addition,
The quantity of tensioner group trap can be increased according to the length of cast tooling 6.
The above is only the utility model preferred embodiment, but the protection scope of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality
With in novel protection scope.
