Description
Technical field
The utility model belongs to mechanical equipment technical field, for carrying out interior hole machined and adverse slope mouth to coiled tubing end hole wall, relates to a kind of built-in coiled tubing processing reamer.
Background technology
Continuous oil pipe tool is connected with coiled tubing by connector.Connector is mainly divided into outconnector and female connector two kinds, and wherein female connector connector is inserted into coiled tubing inside to connect.When using female connector, the surface of matching with connector at coiled tubing inwall is provided with sealing ring.Because coiled tubing is Welding Structure, there is weld seam or welding slag in endoporus, and incision end face exists burr, easily causes the damage of sealing ring.Meanwhile, because coiled tubing is wrapped on cylinder, and the limitation of work site environments, cause coiled tubing end process operation inconvenient, hand sand efficiency is low, and surface accuracy is poor, is difficult to meet seal request.
Utility model content
The utility model object is to provide a kind of built-in coiled tubing processing reamer, and solve existing coiled tubing end processing inconvenience, hand sand efficiency is low, and surface accuracy is poor, is difficult to the problem meeting seal request.
The technical solution adopted in the utility model is, a kind of built-in coiled tubing processing reamer, comprise clamping cylinder, right-hand member and the locking cap screw thread of clamping cylinder are socketed, left end and the guide cylinder screw thread of clamping cylinder are socketed, the centre bore of guide cylinder is installed with reamer bar, and it is affixed that reamer bar and guide cylinder pass through pin, and the external end head of reamer bar is provided with handle; The inner termination that reamer bar puts in clamping cylinder inner chamber is fixedly connected with reamer head.
Built-in coiled tubing processing reamer of the present utility model, is further characterized in that:
Clamping cylinder right-hand member and locking cap adopt the conical surface and ratchet combination, and ratcheted inner surface is processed with slip insert.
Reamer bar is processed with projection, with the groove fit on reamer head.
Guide cylinder external cylindrical surface has multiple window.
Clamping cylinder casing circumference is processed with guide thread.
The beneficial effects of the utility model are: 1) by fixing coiled tubing end, turning handle, drive reamer head to rotate to carry out radial cutting by knife bar transmitting torque; 2) knife bar is connected with guide cylinder pin, drives guide cylinder to rotate, be converted into rectilinear motion thus realize axial feed, carry out axial cutting by screw thread while rotation; 3) reamer head assembling pattern with bolts, can select different size reamer head, wide accommodation according to different wall and processing object; 4) corresponding clamping cylinder can be selected according to the coiled tubing of different size, different size coiled tubing can be adapted to, avoid instrument specification lengthy and jumbled, cost-saving; 5) automatic centering, ensure that machined surface precision, good sealing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device.
In figure, 1. locking cap, 2. clamping cylinder, 3. clamping bolt, 4. reamer head, 5. knife bar, 6. guide cylinder, 7. handle, 8. pin, 9. projection, 10. slip insert.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, the structure of the utility model device is, comprises clamping cylinder 2,
Right-hand member and locking cap 1 screw thread of clamping cylinder 2 are socketed, and clamping cylinder 2 right-hand member and locking cap 1 adopt the conical surface and ratchet combination, are realized the folding of ratchet by the degree of tightness of locking cap 1; Ratcheted inner surface is processed with slip insert, slip insert and coiled tubing exterior surface when ratchet merges, and applies radial load thus firmly grasp coiled tubing to coiled tubing;
Left end and guide cylinder 6 screw thread of clamping cylinder 2 are socketed, and the centre bore of guide cylinder 6 is installed with reamer bar 5, and reamer bar 5 and guide cylinder 6 are by the affixed location of pin 8, and the external end head of reamer bar 5 is provided with handle 7; The inner termination that reamer bar 5 puts in clamping cylinder 2 inner chamber is fixedly connected with reamer head 4 by clamping bolt 3, and clamping bolt 3 is for preventing loosening of reamer head 4; Clamping cylinder 2 casing circumference is processed with longer guide thread, and reamer head 4 can be driven to realize axial feed, and guide cylinder 6 external cylindrical surface has multiple window, with easy disassembly reamer bar 5 and clamping bolt 3;
Reamer bar 5 is processed with projection 9, with the groove fit on reamer head 4, for transmitting torque;
Handle 7 is arranged on reamer bar 5 outer end, turning handle 7, can realize rotation and the axial feed of reamer head 4 simultaneously.
Because reamer head 4 adopts detachable pattern, select the reamer head 4 of different specification size according to coiled tubing wall thickness, or change reamer head dummy formula, thus processing endoporus or groove.
The course of work of the utility model device is:
Need to clear up coiled tubing end before connection coiled tubing and female connector, ensure end inner hole precision and process groove in end.Clamping cylinder 2 can realize the clamping to coiled tubing outer wall, when tightening locking cap 1, due to conical surface extruding, the ratchet of clamping cylinder 2 right-hand member is shunk, clamping coiled tubing outer wall, hand rotation handle 7, by knife bar 5 transmitting torque, reamer head 4 rotates and realizes radial cutting; Meanwhile, knife bar drives guide cylinder 6 to rotate, and realizes axial feed by screw thread conversion.Rotate backward handle then to move round about, reamer head withdrawing.
The utility model is mainly used in clearing up coiled tubing end hole wall, comprises processing endoporus and groove, to ensure that the precision of machined surface meets seal request.Select the cylindrical reamer head of various outer diameter can adapt to the coiled tubing of different wall, select different clamping cylinders can adapt to the coiled tubing of different size, select cylindrical reamer head processing endoporus, select conical reamer head finished edge, process operation is convenient, working (machining) efficiency is high, and surface accuracy is high, and volume is little, lightweight.
