Description
Technical field
It is specifically a kind of in horizontal lathe clamping, centering, turning to intersect vertically the present invention relates to mechanical processing industry
The fixture of axle thread.
Background technology
The screw thread of axis of intersecting vertically can be good at realizing that processing, screw thread are generally logical at present on multiaxis composite processing machine tool
Excessive angle rotary main shaft can carry out Milling Process.The present situation that China's machine adds is that have some high-precision multiaxis Compound Machinings
Lathe, but enterprise still occupies relatively large ratio to horizontal lathe at home, and be still most ideal for screw thread process turning
Processing method.But since thread-whirling axis is vertical with lathe spindle on horizontal lathe, turnery processing can not be directly carried out；Together
When due to clamping axis it is vertical with thread-whirling axis, when turning, screw thread easily deforms, trembles, therefore generally to use exclusive clamps
Tool shifts to thread-whirling shaft rotation coaxial with lathe spindle, while glissando is taken, to realize horizontal lathe turnery processing.This
Sample reduces the difficulty of processing of screw thread, reduces processing cost, and especially for the part of mass production, advantage is brighter
It is aobvious.
In existing processing technology, overturning work is generally used in turning on horizontal lathe for the screw thread for the axis that intersects vertically
Dress is rotated thread-whirling axis to coaxial with lathe spindle by overturning tooling.This processing tool long, work there are the process-cycle
The deficiencies of installing meter is complicated, funds are high, use scope is small, and tooling care and maintenance is all relatively stringenter, increases the system of part
Cause this.For the part of mass production, which is clearly incompatible.
Invention content
To overcome, the process-cycle existing in the prior art is long, use scope is small and care and maintenance is of high cost not
Foot, the present invention propose a kind of fixture for the axle thread that intersects vertically for turnery processing.
The present invention includes clamping plate, torus, locating ring, two gussets and bottom plate.Described two gussets are fixed on clamping
One surface of plate, and the cambered surface of described two gussets together forms the supporting surface of torus, by the circumference table of torus
Face contacts and fixes with the cambered surface of described two gussets；Opening on the torus circumference is located between two gussets, and remote
From clamping plate.The joint face of locating ring circumferential surface is contacted and is fixed with the surface of the clamping plate；The lower surface of the locating ring
It contacts and fixes with the upper surface of the torus；The positioning spigot of the locating ring upper surface is for installing workpiece.Bottom plate welds
It is fixed on the lower face of the torus, and makes the plane on the bottom plate circumference and the aperture position pair on the torus circumference
It answers.
The outer diameter of the clamping plate is more than the radius of gyration of locating ring.Add in the surface periphery that the clamping plate is equipped with gusset
Work has step.
There is " C " font opening of evacuation workpiece on the circumference of the torus.Distinguish at C " the fonts both ends open
It is useful for the positioning screw hole of installation positioning screw.
The outer diameter of the locating ring is more than the outer diameter of the torus；The internal diameter of locating ring is less than the interior of the torus
Diameter.In the locating ring circumferential surface it is machined with joint face, for being welded and fixed with clamping plate surface.In the locating ring upper table
Face is machined with cricoid positioning spigot, and together forming determining workpiece by orthogonal two surfaces of the positioning spigot turns round
The positioning surface at center and machine tool chief axis centre of gyration relative position.
Inner surface at the positioning spigot forms the positioning surface of workpiece centre, and the internal diameter at the positioning spigot and work
The maximum outside diameter of part is identical, and keeps the center of the positioning spigot and the center of workpiece concentric；The step surface of the positioning spigot is formed
The positioning surface of the tooling centre of gyration, distance and the workpiece mounting table face to the workpiece on the step surface surface to clamping plate center add
The distance at work center is equal.
One surface of the gusset is processed as and the matched arc surface of annulus external surface.
There is the mounting hole of supporting screw at the center of the bottom plate；Positioning is symmetrically distributed on the torus circumference
Screw hole, and the central axis of the positioning screw hole is in the axis of the second axis of workpiece.
In actual production, the axle thread difficulty of processing on horizontal lathe why intersects vertically is big, mainly：First, spiral shell
Line rotating shaft is vertical with lathe spindle, can not direct cutted thread；Second, it deformation when how to reduce screw thread process and trembles
It is more difficult.Therefore the key of the present invention is：First, it is necessary to thread-whirling axis is rotated to the position parallel with main shaft, it is horizontal
Lathe could be processed；Second, fixture wants the structure and installation way of reasonable design, chooses rational Set and Positioning benchmark, both had
There is good clamping performance, enough clamping powers can be provided, position inaccurate and clamping deformation are in turn avoided；Third is formulated
Accurate centering mode, solves the problems, such as thread turning centering；4th, fixture wants the damping modes of reasonable design, avoids screw thread
Turning deformation is trembled.
The present invention is according to the design feature of the screw thread for the axis that intersects vertically, and by the clamp structure of reasonable design, it is reasonable to choose
Positioning datum, installation way, reduce clamping workpiece difficulty, realize thread-whirling shaft rotation shift to it is coaxial with lathe spindle, together
When operated convenient for screw thread process, avoid clamping deformation, turning from trembling, reduce tooling manufacture difficulty and cost, overcome existing skill
Deficiency in art.
In use, main shaft clamping fixed body clamping plate outer circle, centering fixed body clamping plate step circles.Positioning screw screws in solid
Determine body torus outer circle, first adjusts both sides positioning screw spacing to larger, to ensure that vertical axis is stretched after part is put into fixed body
Go out torus opening.Part big end is put into fixed body locating ring positioning spigot, is pressed in part admittedly by connecting bolt
Determine body locating ring upper surface, part is made to link together with tooling.Positioning screw and supporting screw are constantly screwed in, until and part
Periphery contacts, and must not pay attention to apply external force to part periphery at this time, only do Auxiliary support.Tighten retainer nut, workpiece dress
Folder, centering finish.
Realize that clamping intersects vertically axle thread part on horizontal lathe, and thread-whirling shaft rotation is changed by using the present invention
It can machining state for parallel with machine tool chief axis.Workpiece is fixed by the positioning bolt on torus, machine tool jaw is made to clamp
Power is not directly placed on workpiece, and workpiece by radial clamping external force, can not effectively reduce workpiece and be deformed caused by clamping, together
When eliminated in traditional processing proposal because of the direct clamping workpiece of main shaft by main shaft clamping tooling, reduce workpiece transmit torque and
Caused deformation.Meanwhile the present invention can prevent turning hang down quadrature axis screw thread when generate vibration, workpiece is reduced by Auxiliary support
Influence of the clamping power to Workpiece Machining Accuracy, to improve the processing quality of product.It is demonstrated experimentally that making product using the present invention
Quality percentage reach 100%, realize product " zero-fault " delivery, and improve production efficiency, improved by original 4h/ parts
0.5h/ parts are arrived.The present invention does not have to turning repeatedly, has saved cost, effect becomes apparent in batch production.
