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
The present invention relates to a kind of drilling clamp, specifically, the present invention relates to a kind of offshore oil conduit joint outer wall drilling clamp.
Background technology
Offshore oil conduit joint is a kind of large-caliber thin-walled conduit coupling, and arranged dividing of internal and external threads structure, is mainly used in being tightly connected between the offshore oil conduit.Because of offshore oil conduit joint residing installation site more special, bear the more complicated active force in seabed, for prevent from coordinating between offshore oil conduit joint and offshore oil conduit produce loosening, avoid producing serious leakage accident, all establish radially the anti-structure of revolving necessary on offshore oil conduit joint outer wall.Anti-main body of revolving structure is to prevent revolving the hole, prevents on the offshore oil conduit joint outer wall of external thread structure revolving the hole at produce in factory.From mechanical machining general knowledge as can be known, freely holing on cylindrical body outer wall acquires a certain degree of difficulty, even successful drilling, the drilling quality is also very poor, and production efficiency is low, can not satisfy batch production requirements.
Summary of the invention
The present invention is mainly for the anti-problem of revolving the hole difficulty of drilling on offshore oil conduit joint outer wall, proposes a kind of simple in structure, location reliably, the drilling quality is good, production efficiency is high offshore oil conduit joint outer wall drilling clamp.
The present invention is achieved through the following technical solutions technical goal.
Offshore oil conduit joint outer wall drilling clamp, it comprises clamp body, bolt, drill jig, pressing plate, screw arbor assembly and gag lever post.Described clamp body is the planar plate members of vertically-arranged, and end face middle part is provided with one perpendicular to working face and the overhanging connecting plate that parallels to the axis.Described pressing plate and screw arbor assembly form two bar positioning support and retaining mechanisms.Its improvements are: described drill jig is the circular arc strip component, interior circular arc radius of curvature equals the workpiece exterior radius, and an end is provided with screw, and the other end is provided with drill jig hole and spacing bayonet socket, drill jig inserts between workpiece and connecting plate, connects with bolt after spacing bayonet socket is located.Described gag lever post is arranged on the working face of clamp body and is positioned at workpiece outer wall place, and gag lever post is provided with and drill jig hole dislocation 90
0Locating slot.
In said structure, the locating slot on gag lever post is semicircle, and the center in the center of locating slot and drill jig hole is on same circumference.
The present invention compared with prior art has following good effect:
1, location structure is simple, and work-handling is quick;
2, through drill jig hole guiding drilling, drilling quality is stable, and production efficiency is high;
3, the anti-hole of revolving of drilling goes to 90
0, with other anti-hole of revolving of the spacing order drilling of semicircular locating slot, decile accurately, reliably.

The specific embodiment
The below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Offshore oil conduit joint outer wall drilling clamp shown in Figure 1, it comprises clamp body 1, bolt 2, drill jig 3, pressing plate 4, screw arbor assembly 5 and gag lever post 6.Described clamp body 1 is the planar plate members of vertically-arranged, is attached to during installation on Drilling machines bench, is provided with one at end face middle part perpendicular to working face and the overhanging connecting plate 1.1 that parallels to the axis.Described pressing plate 4 and screw arbor assembly 5 form two bar positioning support and retaining mechanisms.Described drill jig 3 is the circular arc elongate member, interior circular arc radius of curvature equals the workpiece exterior radius, one end is provided with screw 3.3 and is used for connecting, and the other end is provided with drill jig hole 3.1 and spacing bayonet socket 3.2, and during installation, drill jig 3 inserts between workpiece 7 and connecting plate 1.1 and also is connected with bolt 2.Described gag lever post 6 is arranged on the working face of clamp body 1 and is positioned at workpiece 7 outer wall places, and gag lever post 6 is provided with and drill jig hole 3.1 dislocation 90
0Locating slot 6.1, in the present embodiment, locating slot 6.1 is semicircle, the center in the center of locating slot 6.1 and drill jig hole 3.1 is on same circumference.
The present invention is under location and clamping condition, and along anti-hole and the both sides fabrication hole of revolving on the 3.1 drilling offshore oil conduit joint outer walls of drill jig hole, drilling quality is stable, and production efficiency is high.
