Description
Technical field
The invention belongs to field of machining and machinebuilding technology, it is related to the auxiliary mould of a kind of lathe or Boring machine processing valve body, especially
A kind of positioning when being related to lathe or Boring machine processing valve body, being loaded assists mould.
Background technique
Present invention is generally directed to valve bodies to have revolution machined surface in orthogonal both direction, and two axiss of rotation are total
One kind valve body of line.The valve body shapes of the type are complicated, mostly use Boring machine processing, and occupy larger ratio in valve body processing
Weight, type is more, and quantity is big, since processing centering is difficult, not can guarantee that two axiss of rotation are coplanar to lead to unstable quality,
Seriously affect such product batch production efficiency.
Summary of the invention
In view of the deficiency of the prior art, the present invention provides the auxiliary mould of a kind of lathe or Boring machine processing valve body,
Using mandrel and positioning clamping fixture, so that mandrel, positioning clamping fixture, machine tool chief axis axis co-planar line, effectively reduce correct error to vehicle
Cut the influence of machining accuracy.
Technical scheme is as follows: the auxiliary mould of a kind of lathe or Boring machine processing valve body assists mould by positioning
Mould and two soket head cap screw compositions, positioning clamping fixture is in the form of annular discs, and there is a disc positioning spigot in positioning clamping fixture upper surface, circle
Dish type positioning spigot center successively opens a technique seam allowance, mohs tapered bore and two stepped holes, and two stepped holes are not respectively
The two sides of family name's taper hole, two soket head cap screws are each passed through technique seam allowance and stepped hole and are connected and fixed with lathe or boring machine seat；Institute
The auxiliary mould for stating lathe or Boring machine processing valve body further includes mandrel, and screw rod and auxiliary dismounting device are also equipped on mandrel, described
Outside diameter of mandrel is corresponding with mohs tapered bore internal diameter, is inserted into Mohs in the auxiliary mould use of lathe or Boring machine processing valve body
In taper hole, it to be used for centering.
The disc positioning spigot, mohs tapered bore, technique seam allowance are coaxial, and coaxial with positioning clamping fixture.
The mohs tapered bore penetrates through positioning clamping fixture.
Described two stepped holes are symmetrically distributed in technique seam allowance, and penetrate through positioning clamping fixture.
The disc positioning spigot and workpiece to be processed clamping spot size are at matching relationship.
The present invention mainly utilizes mandrel, dial gauge aligning mould, so that mandrel, mould, lathe or boring spindle axis
It is coplanar.
The present invention is positioned using the matching relationship of mould and workpiece benchmark, it is processed in by centering bring error turn
It is controlled by turnery processing.
Effect of the invention is that converting controllable, quantifiable error for uncontrollable position error.So that processing
Clamping is easy, efficient, stable and controllable for quality, improves mass production efficiency, reduces labor intensity.
