Description
Technical field
The utility model relates to a kind of fixture.Specifically, be used for when being processing cylindrical workpiece to the fixture that is fixed of cylinder dress workpiece.
Background technology
At present in field of machining, be mostly adopt scroll chuck to be fixed cylindrical workpiece during processing cylindrical workpiece.Although adopt scroll chuck can realize the fixing of cylindrical workpiece, because scroll chuck only has its three pawls to contact with cylindrical workpiece, cylindrical workpiece only has three points stressed, stressed very uneven, and cylindrical workpiece even can be caused to be out of shape.Therefore, adopt scroll chuck to be fixed cylindrical workpiece, be difficult to ensure the quality of workpiece to be machined, make the workpiece quality that processes poor.
Utility model content
Problem to be solved in the utility model is to provide a kind of cylindrical workpiece fixture for processing.Adopt this fixture to be fixed cylindrical workpiece, the quality of workpiece to be machined can be ensured, make the workpiece quality that processes higher.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Cylindrical workpiece fixture for processing feature of the present utility model comprises base and up big and down small conical fore-set.Described base is cylindric, at the bottom of its lower end has tin.The surrounding of base is evenly equipped with circular arc-like block, and being spliced into a cross section by described circular arc-like block is the annulus of rectangle.All there is radial expansion head the inner circle side of described circular arc-like block, all there is radial slide opening the base corresponding position corresponding with described radial expansion head, described radial expansion head is that slip shape stretches in radial slide opening, and radial expansion is held in front and is up big and down small coned face.All extension spring is had between contiguous centre in the middle of the downside of described circular arc-like block and at the bottom of the cylinder of described base, under all extension spring unstretched conditions, the coned face of being held in front by all radial expansions forms a up big and down small round taper hole matched with conical fore-set.
All there is circular arc lower convex platform the downside of described circular arc-like block, so as circular arc-like block downside and corresponding radial expansion head downside between form limited step.
Take such scheme, have the following advantages:
As can be seen from the above scheme, because the utility model is made up of the circular arc-like block of base, up big and down small conical fore-set, base surrounding, the radial expansion head of circular arc-like block inner circle side, the radial slide opening of the base corresponding position corresponding with described radial expansion head, described radial expansion head is that slip shape stretches in radial slide opening, and radial expansion is held in front and is up big and down small coned face.All extension spring is had between contiguous centre in the middle of the downside of described circular arc-like block and at the bottom of the cylinder of described base, under all extension spring unstretched conditions, the coned face of being held in front by all radial expansions forms a up big and down small round taper hole matched with conical fore-set.During work, to the thrust that conical fore-set one is downward, radial expansion head can be promoted and radially stretch out, until make the lateral surface of the circular arc-like block of radial expansion head outer end tightly withstand on the medial surface of processed cylindrical workpiece.Compared with background technology, become traditional processed cylindrical workpiece by 3 stressed into multiaspect stressed, make uniform force, thus avoid the generation of cylindrical workpiece deformation.Therefore, adopt the utility model to be fixed cylindrical workpiece, the quality of workpiece to be machined can be guaranteed, make the workpiece quality that processes higher.

Detailed description of the invention
As depicted in figs. 1 and 2, cylindrical workpiece fixture for processing of the present utility model comprises base 2 and conical fore-set 3.Described base 2 is cylindric, at the bottom of its lower end is processed with tin.Described conical fore-set 3 is up big and down small taper shape.The surrounding of described base 2 is evenly equipped with four pieces of circular arc-like blocks 5, and being spliced into a cross section by four pieces of described circular arc-like blocks 5 is the annulus of rectangle.The inner circle side of described circular arc-like block 5 is all processed with radial expansion head 4, base 2 corresponding position corresponding with described radial expansion head 4 is all processed with radial slide opening, described radial expansion head 4 stretches in radial slide opening in slip shape, and radial expansion head 4 inner end is up big and down small coned face.Extension spring 6 is provided with between contiguous centre, in the middle of the downside that extension spring 6 two ends are connected to circular arc-like block 5 and contiguous middle at the bottom of the cylinder of base 2 in the middle of the downside of described circular arc-like block 5 and at the bottom of the cylinder of described base 2.Under all extension spring 6 unstretched conditions, form a up big and down small round taper hole matched with conical fore-set 3 by the coned face of all radial expansion head 4 inner ends.
Wherein, the downside of described circular arc-like block 5 is all processed with circular arc lower convex platform, to form limited step 7 between the downside of circular arc-like block 5 downside and corresponding radial expansion head 4, spacing for carrying out when retracting to radial telescopic head 4.
As shown in Figure 3, when utilizing the utility model to be fixed cylindrical workpiece 1, first above conical fore-set 3, give the pressure that conical fore-set 3 one is downward, by the taper surface of conical fore-set 3 to taper surface pressure of described radial expansion head 4 inner end, make the circular arc-like block 5 of four radial expansion heads 4 and outer end thereof protruding together, until make four circular arc-like blocks 5 withstand the inner circle of processed cylindrical workpiece 1 simultaneously, thus achieve fixing cylindrical workpiece 1.Become traditional processed cylindrical workpiece 1 by 3 stressed into multiaspect stressed, make uniform force, thus avoid the generation of cylindrical workpiece 1 deformation, ensure that the quality of workpiece to be machined.
