This kind of design is very practical when carrying out singleton or small batch production, but when carrying out large batch production, current clamp cover will produce plastic deformation, and the clamping cover loses elasticity, unable normal use.
SUMMERY OF THE UTILITY MODEL
In order to overcome the clamping of the part that exists among the prior art and warp the big problem of the special shape part clamping degree of difficulty at the clamping in-process, the utility model provides a prevent plastic deformation's lathe opening cover, simple structure, safe and reliable, convenient operation, clamping are easy, the processing part is fast, machining efficiency is high, the use is stable, reduce the processing cost of product.
The utility model discloses a following technical scheme realizes:
the utility model provides a lathe opening cover of preventing plastic deformation, includes the opening cover main part, the opening cover main part adopts the trisomy structure of partition equally, the trisomy structure is fixed through the locating pin, and the opening cover main part is fixed through the spring snap ring.
Preferably, the cross sections of the two ends of each three-body structure are provided with positioning holes for penetrating through positioning pins for fixing.
Preferably, an annular groove is formed in the outer circle of the opening sleeve main body and used for being embedded into the spring clamp spring.
Preferably, the three-piece structure is stepped.
Compared with the prior art, the utility model has the advantages as follows:
the current opening cover all is an axial rectangular mouth of processing on opening cover main part lateral wall, makes the opening cover when pressing from both sides tightly, produces an inward elastic deformation, then carries out the clamping to the part, nevertheless will produce plastic deformation after frequently using, can't carry out the clamping to the part, the utility model discloses opening cover main part adopts the components of a whole that can function independently design, establishes a snap ring on opening cover main part excircle and produces an inward elastic deformation, accomplishes the clamping to the part, combines more accurately with the work piece, and positioning accuracy is higher, solves the plastic deformation problem of current opening cover after frequently using.
