CNC pipe machining positioning structure

Abstract

The utility model relates to a kind of CNC pipeline machining positioning structure, comprising: bearing plate, the elbow pipe positioning assembly of being installed in the top surface one end of bearing plate and the straight pipe positioning assembly of being installed in the top surface other end of bearing plate;Elbow pipe positioning assembly includes moving plate, elbow pipe support, heightening stand, locking pin and push-pull cylinder;Straight pipe positioning assembly includes support seat, lifting cylinder and briquetting.The above-mentioned CNC pipeline machining positioning structure, simple structure, convenient to use, elbow pipe support and locking pin position elbow pipe section, support block and briquetting position straight pipe section, realize the complete constraint positioning of pipeline in three-axis direction, effectively avoid the problems such as pipeline displacement, rotation and deformation caused by cutting force in clamping process, ensure the stability of processing datum, improve the machining precision of pipe end thread and sealing surface, improve the assembly quality and sealing performance of product, reduce the scrap rate of high-value pipeline workpiece.
