Description
Technical field
The present invention relates to a kind of fixtures, more particularly, to a kind of folder for lathe in machining irregular contour part
Tool.
Background technique
Numerically controlled lathe is substantially equipped three-jaw or four paws chuck at present, and three-jaw or four paws chuck can only process circle, three
The material of angular, hexagon or square.For the part of irregular contour, current three-jaw or four paws chuck at all can not be direct
Clamping.
To process a conical bore among the aluminum casting for shape irregular, especially part, cone is processed in hole
Toroidal helical oil groove is spent, precision and surface roughness requirements are very high in taper hole, while adding taper hole internal taper toroidal helical oil groove
Feature, it is necessary to upper lathe in machining, and three-jaw or four paws chuck traditional on numerically controlled lathe is unable to satisfy clamping at all and wants
It asks, therefore, urgent need develops a kind of fixture for lathe in machining irregular contour part.
Chinese patent CN202607301U discloses a kind of applied to the fixture for processing irregular workpiece on lathe, does not advise
Then workpiece is non-rotary body, and fixture includes ontology cylindrical, is provided with above and below ontology in the circular side wall of ontology
The opening at both ends, opening include first side, the second side parallel with first side and vertical connection first side and the
The third side of two side faces, first side and second side are extended vertically from circular side wall to the body interior, three sides
It is contacted with wherein three surfaces of irregular workpiece, the center line of ontology passes through the opening, distance of the center line to three sides
It is identical at a distance from corresponding three surfaces as the center of irregular workpiece to irregular workpiece.The fixture advantage it is arrogant with: clamp
Irregular workpiece in opening can reach desired effect when processing on lathe, the effect be irregular workpiece machined surface into
When row aperture, the hole and the machined surface have preferable verticality, position degree.The disadvantage is that zero for shape irregular
Part especially has the part of taper hole structure not applicable, while not being suitable on numerically-controlled machine tool.
Summary of the invention
Simple, application that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of structures
Range is wide, positioning accuracy is high, the fixture versatile, with long service life for lathe in machining irregular contour part.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of fixture for lathe in machining irregular contour part, including support member, positioning element and solid

Line is fastenedly connected.
The clamping screw is interior hexagonal clamping screw.
All components are alloy steel in fixture, and use Overheating Treatment.
The present invention is using numerical control turning machine and the perfect cooperation of this fixture, and cleverly solving common scroll chuck can not clamping
The problem of shape irregular part.The ingenious support panel using three through-holes and fixture on parts to be processed top surface of the present invention
On the positioning of three dowel holes, then be connected by passing through the shaft shoulder positioning screw come from the parts to be processed back side and pass through support
Three fixture nut retaining elements on panel.
Three through-holes on parts to be processed top surface must be worked into the precision of H7, and three by dowel hole before this
Position degree between hole must guarantee within 0.02.Three dowel holes on the support panel of fixture are also the location hole by H7
Precision processing.Fixture corrects after assembling by scroll chuck stationary fixture support base, and among clamping fixture for correcting support panel
Within datum hole and lathe spindle bounce 0.02, then parts to be processed worn from the side of fixture by three shaft shoulder positioning screws
Three good location holes of fixture support panel are crossed, elastic lock washer and nut retaining element, parts to be processed and main shaft are loaded onto
It rotates together, the correction reference hole that cutting tool passes through among fixture support panel directly processes part, loose after the processing is completed
Part can be taken out from side by opening three nuts on fixture support panel.
The present invention thes improvement is that:
(1) solve the problems, such as that scroll chuck can not the fixed irregular contour part to be processed of clamping by this fixture；
(2) irregular contour part to be processed can be positioned using shaft shoulder positioning screw, can also passes through fixed spiral shell
Irregular contour part to be processed is fixed in mother；
(3) prevent irregular contour part to be processed in process from loosening because of vibration using elastic check washer；
(4) clamp body lower half portion is standard cylindrical, can easily dock fixation with common scroll chuck；
(5) all components are alloy steel plus reasonable heat treatment process in fixture, and the service life is longer.
Compared with prior art, of the invention.
