Example Embodiment

[0016] In the following, the present invention will be further explained based on the drawings and the embodiments.

[0017] figure 1 The shown drilling fixture for the outer wall of the offshore oil pipe joint includes a clamp body 1, a bolt 2, a drill mold 3, a pressure plate 4, a screw assembly 5 and a limit rod 6. The clamp body 1 is a vertical plate member, which is attached to the drilling machine workbench during installation, and a connecting plate 1.1 extending perpendicular to the working surface and parallel to the axis is provided in the middle of the top surface. The pressure plate 4 and the screw assembly 5 form a two-rod positioning, supporting and locking mechanism. The drilling jig 3 is in the shape of a circular arc, the radius of curvature of the inner arc is equal to the radius of the outer wall of the workpiece, one end is provided with a screw hole 3.3 for connection, and the other end is provided with a drilling jig hole 3.1 and a limit bayonet 3.2. The mo...

Abstract

The invention discloses an offshore oil pipe joint outer wall drilling fixture comprising a fixture body, bolts, a drilling jig, a pressing plate, a screw unit and a limiting rod. An extending connecting plate, perpendicular to a working surface and parallel to an axis, is arranged on a top surface of the fixture body. The pressing plate and the screw unit form a two-rod supporting-locking structure. The drilling jig is inserted between a workpiece and the connecting plate, positioned at a limiting bayonet and is connected by the bolts. The limiting rod is arranged on the working surface of the fixture body and located on the out wall of the workpiece, and a positioning groove displaced to a drilling-jig hole by 90 degrees is arranged on the limiting rod. Under the condition of positioning and clamping, the offshore oil pipe joint outer wall drilling fixture drills a rotate-resisting hole and auxiliary holes machined on both sides of the outer wall of the offshore oil pipe joint along the drilling-jig hole, and thus, drilling quality is stable, producing efficiency is high and the fixture is adaptable to mass production and utilization.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a drilling jig for the outer wall of an offshore oil conduit joint. Background technique [0002] The offshore oil pipe joint is a large-diameter thin-walled pipe connector, which has an internal and external thread structure, and is mainly used for the sealing connection between offshore oil pipes. Due to the special installation position of the offshore oil pipeline joint, which bears more complex forces on the seabed, in order to prevent loosening between the offshore oil pipeline joint and the offshore oil pipeline and avoid serious leakage accidents, the outer wall of the offshore oil pipeline joint It is necessary to have a radial anti-rotation structure on the top. The main body of the anti-rotation structure is the anti-rotation hole, and the anti-rotation hole on the outer wall of the offshore oil pipe joint with the external thread structure is made in the factory. From the general k...
