FIXING DEVICE FOR HDPE DOUBLE-WALL CORRUGATED PIPE MACHINING

摘要

A fixing device for HDPE double-wall corrugated pipe machining, relating to the technical field of wood machining, and comprising a base (1). A supporting column (2) and a movable column (3) are symmetrically provided on the two sides of the base (1); the supporting column (2) and the movable column (3) is each provided with a mounting cavity (4); the middle of the side of the movable column (3) close to the center of the base (1) is fixedly provided with a fixing column (10); a fastening device (11) is provided in the fixing column (10); a sliding rail (12) is slidably connected to the lower portion of the movable column (3), a mounting recess (13) is provided below the sliding rail (12); a hydraulic cylinder (14) is provided in the mounting recess (13); a telescopic rod (15) is connected to the output end of the hydraulic cylinder (14); a snap-fit seat (16) is provided at the end of the telescopic rod (15); a connecting seat (17) is snap-fitted in the snap-fit seat (16); the connecting seat (17) is fixedly connected to the bottom of the movable column (3). By fixing and supporting the inner wall of a corrugated pipe during machining, rotation and offset of the corrugated pipe during machining are prevented, and machining precision and quality are improved.
