Abstract
Provided is an auxiliary tool for processing a high-precision thin part. A stop block is arranged inside a groove of one end of a base seat, the upper surface of the stop block is higher than the working area surface of the base seat, a locking screw I is in threaded connection with the lower portion of the base seat, and the end portion of the locking screw I is contacted with the side face of the stop block. A protruding boss is arranged at the other end of the base seat, a locking pressing plate with a U-shaped section is arranged on the protruding boss in a fastening mode, a spring is arranged inside a cavity formed by the locking pressing plate and the protruding boss, a locking screw II sequentially penetrates through the locking pressing plate and the spring and is movably connected with the protruding boss. A locating block is arranged on the upper end face of the base seat. Inward chamfers are arranged on the inner end sides above the stop block and the locking pressing plate, and the bottom edges of the chamfers coincide with the upper surface of the base seat. The auxiliary tool not only is simple in structure, but also can improve clamping speed, and prevent cocking in a grinding process and other problems.
Description
Technical field
The utility model relates to a kind of auxiliary mould for the slim part of machining high-precision, is particularly useful for the grinding of the thin-walled parts of high accuracy non-ferrous metal.
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 problems to be solved in the utility model provides a kind of auxiliary mould for the slim part of machining high-precision and adopts simultaneously auxiliary mould, and this auxiliary mould is not only simple in structure, and can improve clamping speed, the problem such as perk when preventing grinding.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: the auxiliary mould that is used for the slim part of machining high-precision, in the groove of an end of base, be provided with block, the upper surface of block is higher than the surface, workspace of base, 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 U-shaped locking pressure plate is fastened on the boss, is provided with spring in the cavity of locking pressure plate and boss formation, and the lock-screw II is passed successively locking pressure plate and spring and boss and is flexibly connected; Front end face at base is provided with locating piece; Interior distolateral above block and locking pressure plate is provided with inside chamfering, and 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.
The auxiliary mould that should be used for the slim part of machining high-precision adopts the structure of two ends clamping, with positioning by 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.
