Clamping deformation resistant jig for machining large-diameter elbow
InactiveCN102139457AGuaranteed machining accuracyAbundant resourcesPositioning apparatusMetal-working holdersThin walledEngineering
The invention discloses a clamping deformation resistant jig for machining a large-diameter elbow. Three combined clamping blocks are arranged on a clamping base plate, each combined clamping block consists of an upper clamping block, a lower clamping block, a base plate and connecting bolts, inner sides of the upper clamping blocks and the lower clamping blocks are provided with circular arc-shaped gaps and form a circle consistent with the outer circumference of an elbow to be machined after closed, the upper clamping blocks and the lower clamping blocks are connected and fastened by the connecting bolts, and the base plates are arranged at the bottoms of the lower clamping blocks and are provided with chutes. Lock bolts pass through the chutes on the base plates of the combined clamping blocks and fix the combined clamping blocks on the clamping base plate after being fastened. In the invention, the large-diameter elbow is clamped by adopting a way of directly clamping a pipe blank in a surface-contact manner, thus the elbow does not generate a radial compaction force in the clamping process and is not easy to generate the radial forced deformation and the torsional moment; in addition, the clamping deformation resistant jig disclosed by the invention is applied to machining of a large-diameter thin-wall elbow machine, thereby ensuring the machining precision of the elbow.

The device of the invention comprises a vacuumizing interface matched and connected with a squeezing-protecting cuff of a wire squeezing-protecting sheath machine, a vacuum pipeline and a vacuum pump, and is characterized in that an air storage tank is connected on the vacuum pipeline in series; an air outlet of the air storage tank is connected with the vacuum pump, while an air inlet of the air storage tank is connected with one end of the vacuum pipeline, and the other end of the vacuum pipeline is connected with the vacuumizing interface. The device of the invention has the advantages that as the air storage tank is arranged on the vacuum pipeline of the vacuum device in the prior art, the stability of a wire in the squeezing-protecting cuff can be guaranteed, and even if a machine works once again after shutdown, the air storage tank has the balance function, therefore, fluctuation of the wire can be avoided.
