Description

Flange processing positioning jig Technical Field The utility model relates to the technical field of positioning tools, in particular to a flange processing positioning tool. Background The flange shown in fig. 1 is cylindrical as a whole, the end face of the flange needs to be drilled after casting and forming, the flange is fixed by a bench vice through the traditional driller processing for the end face of the flange, and then drilling is carried out. Disclosure of utility model The utility model provides a flange machining positioning jig, and aims to solve the technical problem that the existing flange is easy to damage screw threads and is low in efficiency caused by inconvenient clamping. In order to achieve the purpose, the flange machining and positioning jig comprises a circular bottom plate, wherein a positioning column is arranged on the circular bottom plate, a gland is detachably arranged on the positioning column, a plurality of supporting blocks are circumferentially arranged on the circular bottom plate, and a positioning step is arranged on one side, facing the center of the circular bottom plate, of each supporting block. Further, the gland comprises a plurality of pressing blocks extending in the circumferential direction, and the pressing blocks are provided with U-shaped notches. Further, a fixing block is further arranged on the round bottom plate, and the fixing block is horizontally provided with a T-shaped protruding block. Further, two positioning rods are arranged on the positioning column, a guide hole is formed in the gland, and the positioning rods penetrate through the guide hole. Further, let the briquetting be the X piece, the supporting shoe be the Y piece, X=Y. Further, a plurality of threaded holes are formed in the round bottom plate. Compared with the prior art, the utility model has the beneficial effects that: The flange machining positioning jig is simple in structure and reasonable and ingenious in design, and comprises a circular bottom plate, wherein a positioning column is arranged on the circular bottom plate, a gland is detachably arranged on the positioning column, a plurality of supporting blocks are circumferentially arranged on the circular bottom plate, and a positioning step is arranged on one side, facing the center of the circular bottom plate, of each supporting block. When the flange drilling device is used, the end face of the flange to be drilled is upwards placed on the positioning step of the supporting block, then the gland is locked on the positioning column through the bolts, and the gland presses the flange on the supporting block, so that the flange can be quickly fixed.
