Description
Technical field
It the utility model is related to machining technique field, more particularly to a kind of fixture for solid bar bore hole.
Background technology
The boring jig principle of profile special section end face punching at present is all to use instrumented spring perch, in spring perch
An endoporus as profile shapes size is carved in end face with machining center, and then steel are put into fixture internal diameter, fixture folder
Next carry out turnery processing.Spring perch clamping principle is rear pull type fastening means, and clamping face is tapered when spring perch clamps,
When so drilling after material end face stress material external diameter will run-off the straight, cause processed hole and profile position degree deviation
Greatly, it is difficult to the position of control hole.
Utility model content
In view of the deficienciess of the prior art, main purpose of the present utility model is that processing essence can be improved by providing one kind
The fixture for solid bar bore hole of degree.
To achieve the above object, the utility model provides following technical scheme：A kind of folder for solid bar bore hole
There are the solid bar of kidney-shaped, including clamp body in tool, including section, are provided with the clamp body for placing putting for solid bar
Chamber is put, the side of the placed cavity is provided with support block, and the opposite side of the placed cavity is provided with parallel sliding block, the support block
And the arc clamping face being bonded with solid bar is provided with parallel sliding block, two guiding spiral shells are provided with the placed cavity
Silk, the parallel sliding block are inserted into two guide screws, and preloading spring, the fixture are provided with described two guide screws
The side of body is provided with locating piece, be provided with the locating piece insertion clamp body in fastening screw, the fastening screw with
Parallel sliding block is supported and set.
Preferably, it is arranged with balancing spring on the fastening screw.
Preferably, the profile of the clamp body is circle, and the clamp body is fixed by numerical control Three-jaw fixture.
Preferably, the fastening screw is M12 screws.
The utility model has the following advantages that one kind of the present utility model is used for solid bar bore hole relative to prior art
Fixture, when in use, solid bar is put into placed cavity first, one end of solid bar clamps against the arc of support block
Face, the other end of solid bar set against the arc clamping face of parallel sliding block, then fasten fastening screw, fasten spiral shell
Bar pushes parallel sliding block along placed cavity until fasten completely with solid bar, can then proceed by bore hole operation,
As long as unclamp fastening screw slidably to take out the solid bar processed after parallel sliding block.The effect of preloading spring is so that
Parallel sliding block can be by more uniform elastic force so that run trace of the parallel sliding block in placed cavity is linear, ensures solid
Bar is by good support.Clamp body cuts two ensured to the solid bar of kidney-shaped using low-speed WEDM internal-and external diameter isochrone
Individual side clamping face is substantially parallel.The beneficial effect of scheme of the present utility model is to improve special section clamping precision, ensures processing
The internal diameter of the solid bar gone out is vertical with end face.
