Abstract
The invention relates to a high-precision thin part processing method which comprises the following steps of: 1) carrying out ageing treatment on a thin part and removing inner stress of the part; 2) carrying out wire cutting on the appearance to achieve the size requirement; 3) milling the end face of a non-work area of the thin part into a chamfered angle and clamping the thin part in auxiliary tool equipment, wherein the clamping end of the auxiliary tool equipment is provided with a reverse chamfered angle which is matched with the chamfered angle on the thin part; and 4) grinding the surface of the thin part. The processing method is not only capable of solving the problems of bad part rigidity, clamping deformation in clamping and the like, but also simple in step and high in processing efficiency. At the same time, the auxiliary tool equipment is used for improving the clamping speed and preventing the problems of tilting in grinding and the like.
Description
Technical field
The present invention relates to the slim machining parts of a kind of high accuracy, be particularly useful for the grinding of the thin-walled parts of high accuracy non-ferrous metal, and the auxiliary mould of processing this thin-walled parts.
Background technology
Non-ferrous metal is especially shielded part, and it has just waken up relatively poor, yielding, is adding man-hour, and its behavior tolerance and surface roughness are difficult to guarantee that not only working (machining) efficiency is low, and product quality does not reach specification requirement.
Summary of the invention
The technical problem that the present invention will solve provides slim machining parts of a kind of high accuracy and auxiliary mould thereof, and this processing method causes problems such as clamping distortion when not only having solved part poor rigidity, clamping, and step is simple, and working (machining) efficiency is high.Adopt auxiliary mould to improve clamping speed simultaneously, problem such as perk when preventing grinding.
For overcoming the above problems, concrete technical scheme of the present invention is following: the slim machining parts of a kind of high accuracy may further comprise the steps:
1) thin-walled parts is carried out Ageing Treatment, remove the internal stress of part;
2) profile is carried out the line cutting, reached dimensional requirement;
3) facing cut with the nonclient area of thin-walled parts becomes chamfering, and with the thin-walled parts clamping in auxiliary mould, the bare terminal end of auxiliary mould be provided with thin-walled parts on chamfering to the reverse chamfering that cooperates;
4) grinding is carried out on the surface of thin-walled parts.
A kind of auxiliary mould is provided with block in the groove of an end of base, the upper surface of block is higher than the surface, workspace of base, and the lock-screw I connects the end of lock-screw I and the contacts side surfaces of block from the end thread of base; The other end at base is provided with boss, and the cross section is that the locking pressure plate of U type is fastened on the boss, in the cavity of locking pressure plate and boss formation, is provided with spring, and the lock-screw II is passed locking pressure plate and spring and boss successively and flexibly connected; Be provided with locating piece at the front end of base face; Distolaterally in above block and locking pressure plate be provided with inside chamfering, the base of chamfering overlaps with the upper surface of base.
The middle part that described block and locking pressure plate are provided with the end face of chamfering is provided with technology groove.
This thin-walled parts adopts above-mentioned steps to process the appearance and size that can guarantee thin-walled parts through Ageing Treatment and line cutting; Through the grinding again of the clamping between chamfering; Avoid the problem of part deformation, perk, guaranteed behavior tolerance and the surface roughness of part.
The structure that auxiliary mould adopts two ends to clamp, with positioning through the chamfering on the frock, in the process of grinding thin-walled parts, the distortion meeting of thin-walled parts is extended to the direction of chamfering, so can not produce part deformation and perk simultaneously.
