The milling and clamping device has the advantages of small clamping deformation, reliable performance, low cost, convenient in assembly and disassembly, increases the milling efficiency, and is suitable for difficult-clamping and mass-produced the disc type thin-wall parts.
Description
Technical field
The invention belongs to Machining Technology field, be specifically related to a kind of device of disc type thin-walled parts Milling Process.
Background technology
Aluminum alloy materials thin-walled parts, because its quality is light, intensity is good, is widely used in the fields such as Aero-Space, precision instrumentation, but its poor rigidity, clamping difficulty.The quantity of once going into operation is many.The mode of being installed of conventional milling disc type thin-walled parts is to block its cylindrical by three-jaw.Shortcoming is: when clamping force is too little, during milling, part can rotate in three-jaw; When clamping force is too large, part meeting is because be out of shape by clamping force, and along with the carrying out of processing, part is more and more thinner, and detail rigidity declines thereupon, and machining deformation aggravation, causes part to be trembled, and affects machined surface quality, and process shakiness and efficiency are low.
Summary of the invention
In order to solve the problem of prior art, the object of this invention is to provide a kind of device of milling disc type thin-walled parts.
Disc type thin-walled parts milling clamping device of the present invention, comprises matrix, back of the body cap, two screws, and one end of described matrix is connected with back of the body cap thread, and described screw screws in two screwed holes on back of the body cap and holds out against matrix.
Technique effect of the present invention: matrix of the present invention compresses after part to be processed by screw threads for fastening with back of the body cap,
1. make parts fixation to be processed stressed evenly, can reduce machining deformation;
2. make on part to be processed and matrix heavy stand hole contact area large, increase clamping intensity, can solve part and tremble;
3. make part machining deformation to be processed reduce, not tremble, can improve machined surface quality;
4. screw threads for fastening, end face location, make process stable, improved working (machining) efficiency.
The heavy stand hole that the present invention can realize part to be processed bottom surface and matrix closely cooperates, and thrust application point symmetrically.Solved carry out of prior art along with processing, part is more and more thinner, the technical problem of trembling of workpiece to be processed; Can avoid causing the part distortion that is installed because of the power of being installed simultaneously.To guarantee machining accuracy.Clamping deformation of the present invention is little, dependable performance, cost are low, easy to loading and unloading, can greatly improve milling efficiency, alleviate working strength, has improved machined surface quality, and the present invention is applicable in the batch production of clamping difficulty.
