Abstract
The invention discloses a clamp for drilling a marine oil guide pipe connector rotation-proof hole. The clamp comprises a main board, a top block, a template and a bolt. The vertically-arranged main board is attached to a vertical plane of a working table of a drilling machine. A table shoulder which is located with an inner hole of a workpiece in a matched mode is arranged on a board plane facing outwards. The middle of the top edge of the main board is connected with the top block, a suspended arm of the board plane facing outwards extends out to form the top block. A through hole is formed in the middle of the board plane of the top block, and the bolt is located and installed in the through hole. The gap between the bottom face of the top block and the outer wall, with the largest diameter, of the workpiece is equal to the thickness of a main body of the template. The template is a long-strip-shaped and arc board block. An inner hook and a drill jig sleeve are arranged at one end of the template, wherein the hook is bent inwards, and the drill jig sleeve is provided with a drilled rotation-proof hole and a process hole. The template is plugged between the top block and the workpiece and is stopped through a position-clamping groove. The bolt is plugged into the top block to be connected with the template, and a locating structure for drilling the outer wall, with the largest diameter, of the workpiece in a radial mode. The clamp is simple in structure, easy to disassemble and assemble, accurate in locating, good in drilling quality, high in production efficiency, and capable of meeting requirements on drilling marine oil guide pipe connector rotation-proof holes of various standards through change of locating sizes.
Description
Technical field
The present invention relates to a kind of anchor clamps that are used for machine cut processing, particularly a kind of anti-hole anchor clamps that revolve of drilling offshore oil pipe joint that are used for.
Background technology
Offshore oil pipe joint installation site is subjected to sea beat under water for a long time, and for preventing to connect the loosening leakage accident that causes, special being provided with on offshore oil pipe joint outer wall radially prevents revolving the hole.Because of the offshore oil pipe joint belongs to large-caliber thin-walled pipe component, pipe outer wall rigidity is poor slightly, and directly the anti-hole of revolving of drilling is difficult except that the location on the curved surface outer wall, and outside the working (machining) efficiency difference, the accuracy of boring is also relatively poor.Generally adopt the bushing type drill jig to revolve the drilling tool in hole in the industry production line,, can overcome the problems referred to above fully, can accurately locate highly-efficient processing although the bushing type Drilling Jig Structure is simple, practical as drilling is anti-.But bushing type drill jig volume is big, Heavy Weight, and frequent loading and unloading must strengthen operative employee's labour intensity in the batch production process.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, easy for installation, volume is little, in light weight, the anti-hole anchor clamps that revolve of location reliable drilling offshore oil pipe joint.
The present invention is achieved through the following technical solutions technical goal.
The pipe joint of a kind of drilling offshore oil is anti-revolves the hole anchor clamps, and it comprises mainboard, jacking block, template and bolt.Its improvements are: described mainboard is a planar plate members, and the mainboard of vertically-arranged relies on the Drilling machines bench vertical plane with the plane, and plate face outwardly is provided with the evagination shoulder and cooperates the location with the workpiece endoporus, at the mainboard top margin jacking block that stretches out towards the outer plate surface cantilever that connects placed in the middle.Described jacking block plate face middle part is provided with through hole location and installation bolt, and the gap between top board bottom surface and the maximum diamater of work outer wall equals main template body thickness.Described template is rectangular arc plate, inwall cooperates with maximum diamater of work outer wall, both radius of curvature equate, plate face length degree direction one end inwall is provided with the interior hook of one section bending inwardly along two edges, in having on the end plate face of hook, the location is provided with the anti-drill jig cover 3.1 in hole and the drill jig cover of fabrication hole of revolving of drilling workpiece, plate face other end middle part be provided with jacking block on the supporting screwed hole of through hole, the bolt that penetrates from top board connects template, constitutes the location structure to maximum diamater of work outer wall radial bore.
In the said structure, the interior dogging position thickness of template one end equals the thickness of maximum diamater of work outer wall, and both matched in clearance are convenient to loading and unloading.
The present invention compared with prior art has following good effect:
1, the shoulder location structure is simple, and accurate positioning, loading and unloading are easily;
2, under location condition, hole drilling steady quality, production efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the formwork structure enlarged diagram among Fig. 1.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Drilling offshore oil pipe joint shown in Figure 1 is anti-revolves the hole anchor clamps, and these anchor clamps are attached to the Drilling machines bench vertical plane, and it comprises mainboard 1, jacking block 2, template 3 and bolt 4.Described mainboard 1 is a planar plate members, is the main body of anchor clamps.The mainboard 1 of vertically-arranged relies on the Drilling machines bench vertical plane with the plane, and plate face outwardly is provided with the evagination shoulder and cooperates the location with workpiece 5 endoporus, at the mainboard 1 top margin jacking block 2 that stretches out towards the outer plate surface cantilever that connects placed in the middle.Described jacking block 2 plate faces middle part is provided with through hole location and installation bolt 4, and the gap between top board 2 bottom surfaces and the workpiece 5 maximum gauge outer walls equals template 3 body thickness.Described template 3 is rectangular arc plate, and inwall cooperates with workpiece 5 maximum gauge outer walls, and both radius of curvature equate.Suitable two edges of one end inwall of template 3 length directions are provided with the interior hook 3.2 of one section bending inwardly, and the screens groove that forms between interior hook 3.2 and the inwall equals the thickness of workpiece 5 maximum gauge outer walls, both matched in clearance.In having on the end plate face of hook 3.2, the location is provided with the drilling workpiece 5 anti-drill jig cover 3.1 in hole and the drill jig covers 3.3 of fabrication hole of revolving, plate face other end middle part be provided with jacking block 2 on the supporting screwed hole of through hole, the bolt 4 that penetrates from top board 2 connects template 3, constitutes the location structure to workpiece 5 maximum gauge outer wall radial bores.
Present embodiment is used for that the pipe joint of drilling DN800 offshore oil is anti-revolves the hole, and the endoporus of this workpiece 5 is of a size of Ф 30mm, and the shoulder that mainboard 1 is equipped with on the outer plate surface is of a size of Ф 800mm.The outer wall thickness 12mm of workpiece 5 maximum gauges, the screens groove that template 3 is provided with is similarly 12mm, and for the ease of template 3 loading and unloading, both are matched in clearance.Earlier workpiece 5 is installed on the mainboard 1 before the drilling, between workpiece 5 and jacking block 2, fill in frid 3, template 3 is with screens groove stop bit, then bolt 4 is inserted the template 3 that is located by connecting from the through hole of jacking block 2, the drill jig that drilling machine presets according to template 3 overlaps 3.1 drillings to be prevented revolving the hole, overlaps 3.2 drilling technique holes according to drill jig.The present invention is simple in structure, and loading and unloading are easy, accurate positioning, and drilling quality is good, the production efficiency height.
