Abstract
The utility model discloses an offshore oil conduit joint outer wall drilling clamp which comprises a clamp body, a bolt, a drilling jig, a pressure plate, a screw component and a limiting rod. wherein the top surface of the clamp body is provided with an outward-extending connection plate which is vertical to the working surface and parallel to the axis; the pressure plate and the screw component form a two-rod positioning support and locking structure; the drilling jig is inserted between a workpiece and a connection plate and connected by a bolt after being positioned by a limiting bayonet; the limiting rod is mounted on the working surface of the clamp and located on the outer wall of the workpiece; and a positioning groove staggered with the drilling jig hole for 90 degrees is arranged on the limiting rod. The offshore oil conduit joint outer wall drilling clamp disclosed by the utility model drills an anti-rotation hole on the outer wall of an offshore oil conduit joint and auxiliary holes on the two sides along the drilling jig hole under the positioning and clamping conditions, has stable drilling quality and high production efficiency, and is particularly suitable for large-scale production.
Description
Technical field
The utility model relates to a kind of drilling anchor clamps, and specifically, the utility model relates to a kind of offshore oil pipe joint outer wall boring grab.
Background technology
The offshore oil pipe joint is a kind of large-caliber thin-walled conduit coupling, and the branch of internal and external threads structure is arranged, and is mainly used in being tightly connected between the offshore oil conduit.Because of the residing installation site of offshore oil pipe joint more special; Bear the complicated active force in seabed; For prevent to cooperate between offshore oil pipe joint and the offshore oil conduit produce loosening; Avoid producing serious leakage accident, it is necessary on offshore oil pipe joint outer wall, all to establish radially the anti-structure of revolving.Anti-main body of revolving structure is to prevent revolving the hole, prevents on the offshore oil pipe joint outer wall of external thread structure revolving the hole at produce in factory.Can know that from mechanical cut general knowledge on the cylinder outer wall, freely holing 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.
The utility model content
The utility model is primarily aimed at the anti-difficult problem in hole of revolving of on offshore oil pipe joint outer wall drilling, proposes a kind of simple in structure, the location is reliable, the drilling quality is good, production efficiency is high offshore oil pipe joint outer wall boring grab.
The utility model is realized technical goal through following technical proposals.
Offshore oil pipe joint outer wall boring grab, it comprises clamp body, bolt, drill jig, pressing plate, screw arbor assembly and gag lever post.Said 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.Said pressing plate and screw arbor assembly are formed two bar positioning support and retaining mechanisms.Its improvements are: said 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 the connecting plate, connects with bolt in back, spacing bayonet socket location.Said gag lever post is installed in 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 the said structure, the locating slot on the gag lever post is semicircle, and the center in the center of locating slot and drill jig hole is on same circumference.
The utility model compared with prior art has following good effect:
1, location structure is simple, and work-handling is quick;
2, the guiding drilling through the drill jig hole, 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, five equilibrium accurately, reliably.

The specific embodiment
According to accompanying drawing and combine embodiment, the utility model is described further below.
Offshore oil pipe joint outer wall boring grab 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.Said clamp body 1 is the planar plate members of vertically-arranged, is attached to during installation on the 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.Said pressing plate 4 is formed two bar positioning support and retaining mechanisms with screw arbor assembly 5.Said 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 drill jig 3 inserts between workpiece 7 and the connecting plate 1.1 and also is connected with bolt 2 during installation.Said gag lever post 6 is installed in 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 3.1 dislocation 90 of drill jig hole
0Locating slot 6.1, locating slot 6.1 is semicircle in the present embodiment, the center in the center of locating slot 6.1 and drill jig hole 3.1 is on same circumference.
The utility model 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 pipe joint outer walls of drill jig hole, drilling quality is stable, and production efficiency is high.
