Abstract
The utility model discloses a special lathe for petroleum casing pipes and couplings. The special lathe comprises a lathe bed, wherein a guide rail is arranged on one side of the lathe bed; a tool holder is positioned on the guide rail and can move toward or far away from the lathe bed along the guide rail in a reciprocating manner; a turning tool is mounted on the tool holder and comprises a tool bar mounted on the tool holder and a tool bit fixed on the tool bar; a chuck is arranged on the lathe bed on one side close to the tool holder; an adjustable jack catch is mounted on the chuck; and the jack catch is connected with a power system and can do clamping or opening reciprocating motion along the chuck under the drive of the power system. Through the adoption of the structure, the special lathe for the petroleum casing pipes and the couplings can realize the turning of petroleum casing pipes and couplings in large specifications ranging from 20 to 30 inches.
Description
Technical field
The utility model relates to the production process equipment in a kind of oil drilling field, especially a kind of petroleum casing pipe and box cupling special purpose lathe.
Background technology
Petroleum casing pipe is the important equipment of oil drilling, is used for the oil well probing and is mainly used in after drilling process and the completion support to the borehole wall, with the normal operation of whole oil well after the carrying out of assurance drilling process and the completion.Petroleum casing pipe is a kind of heavy caliber pipe, plays the effect of anchor stone oil and gas oil well wall or wellhole.Sleeve pipe is to insert in the wellhole, fixes with cement, separates rock stratum and borehole collapse and guarantees that drilling mud circulates to prevent well, so that the probing exploitation.Lathe is the common equipment in petroleum casing pipe and the box cupling production technology.Petroleum casing pipe specification limit in existing international standard API is that 4-1/2 is very little to 20 cun, the lathe that therefore existing one-tenth produces petroleum casing pipe and box cupling can only satisfy the requirement of above-mentioned specification usually, yet for 20 cun to 30 cun large specification petroleum casing pipe and box cupling, the lathe that there is no for this type of specification product special use carries out production and processing.
The utility model content
The technical problems to be solved in the utility model provides a kind of petroleum casing pipe and the box cupling special purpose lathe that can process large specification petroleum casing pipe and box cupling.
For addressing the above problem, a kind of petroleum casing pipe of the present utility model and box cupling special purpose lathe is characterized in that: comprise lathe bed, a side of lathe bed is provided with guide rail, knife rest be positioned on the guide rail and can along guide rail do near or away from the reciprocating motion of lathe bed; On the described knife rest lathe tool is installed, this lathe tool is comprised of the cutter head that is installed in the knife bar on the knife rest and be fixed on the knife bar; Described lathe bed is provided with chuck near a side of knife rest, is equipped with on the chuck and can regulates claw, and described claw links to each other with dynamical system, can do the reciprocating motion that tightens or open at the chute on the chuck under the drive of dynamical system.
Be provided with the first lowering or hoisting gear on the described knife rest, this first lowering or hoisting gear links to each other with dynamical system, can carry out elevating movement under the effect of dynamical system.
Be provided with the second lowering or hoisting gear on the described lathe bed, this second lowering or hoisting gear links to each other with dynamical system, can carry out elevating movement under the effect of dynamical system.
Adopt petroleum casing pipe and the box cupling special purpose lathe of the utility model structure, compared with prior art have following beneficial effect: on the one hand, by the first lowering or hoisting gear is set at knife rest, can adjust the height of knife rest; On the other hand by the second lowering or hoisting gear is set at lathe bed, can adjust the height of headstock, and use instead and be fit to the chuck that large specification petroleum casing pipe and box cupling are processed, and be equipped with the claw regulated on chuck, thereby can realize the turning processing to 20 cun to 30 cun large specification petroleum casing pipe and box cupling.
Description of drawings
Fig. 1 is the structural representation of the utility model petroleum casing pipe and box cupling special purpose lathe.
The specific embodiment
In order to make those skilled in the art person understand better technical solutions of the utility model, the utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, a kind of petroleum casing pipe of the present utility model and box cupling special purpose lathe comprise lathe bed 1, and lathe bed 1 is provided with chuck 2 on the lathe bed 1, are used for machined piece 3 is installed; Be equipped with on the described chuck 2 and can regulate claw 4, described claw 4 is four, and evenly branch made progress in the week of chuck 2; Described claw 4 links to each other with the dynamical system (not shown), the reciprocating motion that can do chucking or open at the chute 5 on the chuck 2 under the drive of dynamical system, thus realize loading and unloading to machined piece 3.
Be provided with guide rail 6 near a side of described lathe bed 1 upper chuck 2, knife rest 7 be positioned on the guide rail 6 and can along guide rail 6 do near or away from the reciprocating motion of lathe bed 1; On the described knife rest 7 lathe tool 8 is installed, this lathe tool is comprised of the cutter head that is installed in the knife bar on the knife rest and be fixed on the knife bar, is used for the machined piece 3 in the chuck 2 is carried out turning processing.
Be provided with the first lowering or hoisting gear 9 on the described knife rest 7, this first lowering or hoisting gear 9 links to each other with dynamical system, can carry out elevating movement under the effect of dynamical system, thus the operation height of regulating knife rest 7 and being positioned at the lathe tool 8 on the knife rest 7.
Simultaneously, also be provided with the second lowering or hoisting gear 10 on described lathe bed 1, this second lowering or hoisting gear 10 links to each other with dynamical system, can carry out elevating movement under the effect of dynamical system.
