The technical problem that the utility model solves realizes by the following technical solutions:
The utility model for clamping the design feature of the spring chuck of irregular contour part on flat-nose pliers is: elastic nip, for adopting the integrated elastic structural slab of flexible hinge, is provided with placement and is held the die cavity of part, and adopt the double swing-bar structure of flexible hinge; Elastic nip is fixed on elastic nip base by soket head cap screw, between elastic nip and elastic nip base, is placed with copper backing; Swing jaw is contained on swing jaw base by swinging axle, and swing jaw can swing around swinging axle, and is realized spacing while swinging and resetted by limit shaft, O-ring seals; Swinging axle is interference fit with hole corresponding on swing jaw base, and swinging axle is matched in clearance with hole corresponding on swing jaw, and swinging axle pad and nut are arranged on the end of thread of swinging axle; Limit shaft is interference fit with hole corresponding on swing jaw base, and O-ring seals, limit shaft pad and circlip for shaft are arranged on limit shaft upper end; Elastic nip base and swing jaw floor installation are in the jaw position of flat-nose pliers.
The utility model is also for clamping the design feature of the spring chuck of irregular contour part on flat-nose pliers:
Described elastic nip is provided with die cavity and the two groups of double swing-bar structures that adopt flexible hinge that two placements are held part.
On described elastic nip, place the die cavity be held part and the profile that is held part is matched in clearance under clamp position not.
Described elastic nip has elasticity, and material is spring steel, and through heat treatment.
Described elastic nip is processed into by line cutting clamped one time.
Compared with the prior art, the effect that the utility model is useful is embodied in:
1, the utility model can once clamp two or four irregular parts of profile on flat-nose pliers, not only shorten the parts fixation time, improve machine tooling efficiency 50-80%, also improved the positioning precision of clamping part and repeated clamp precision, thereby having improved the machining accuracy of part.
2, the utility model is not only used on the flat-nose pliers of single jaw and can also be used on two-jawed flat-nose pliers.
