Detailed Description
In the embodiment, as shown in fig. 1, 2, 3 and 4, the portable pipe external aligning device comprises a tightening base 1 and a movable tightening cover 7, the cross section of which is semicircular, the tightening base 1 and the movable tightening cover 7 can form a cylinder with two open ends, and the inner diameters of the tightening base 1 and the movable tightening cover 7 are finely processed by a lathe according to the outer diameter of a welding pipe of national standard, so that the tightening base can be tightly fitted with the welding pipe.
The bottom of the tightening base 1 is provided with two support legs 2, two sides of the movable tightening cover 7 are respectively welded with a fixed connecting piece 6, the fixed connecting piece 6 on one side is provided with a fixed hole, and the fixed connecting piece 6 on the other side is provided with a bolt hole 3; the fixed connecting piece 6 at one side is hinged with the supporting leg 2 at one side of the tightening base 1 through a fixed hole and a locking bolt 5, so that the movable tightening cover 7 can be flexibly opened and closed on the tightening base 1;
the supporting leg 2 at the other side of the tightening base 1 is provided with a locking hole for fixing a positioning type indexing pin (4), and the positioning type indexing pin 4 fixes a movable tightening cover 7 through a bolt hole 3 and the locking hole.
The central line of the top of the movable tightening cover 7 is horizontally provided with three tightening screw rods with hand wheels 11 in parallel, the tightening screw rods are connected with the movable tightening cover 7 through tightening holes, the middle tightening screw rod is a pipe orifice tightening screw rod 8, the tightening screw rods on the two sides are pipeline tightening screw rods 9, the pipe orifice tightening screw rods 8 are used for tightening the pipe orifices of the pipelines, and the pipeline tightening screw rods 9 are used for tightening the pipelines on the left side and the right side; the tightening action of the three tightening screws is accomplished by means of the hand wheel 11 at the top thereof.
