Abstract
The utility model discloses a special processing machine which belongs geological exploration industry and is composed of an adjustable clamp tool, a milling head, a main shaft, a screw rod, a feeding and retracting knife mechanism, a dynamic force mechanism, etc. The utility model is characterized in that a work piece is fixed by the adjustable clamp tool and does not do rotation motion. The shaft center of the main shaft and the milling knife rotation center of the milling knife head have eccentric distance, and the forming of screw threads is totally achieved by the resultant motion of the milling knife. The machine weight of the utility model only is one fifth of a common lathe, is easy in removing and transporting, and is suitable for screw thread processing of field drilling pipes of geology, metallurgy and coal geology.
Description
The utility model is a kind of special purpose machine tool of processing industry probing tubing screw threads such as geology, metallurgy, coalfield.
Up to the present, the mode of processing probing tubing screw thread is that turning forms on special use or engine lathe.This processing mode has following several disadvantage: the probing workload in geology, wild gold, coalfield is operation in the open air basically, much is the work of separate unit rig but have, and being equipped with lathe, to satisfy the processing of tubing screw thread promptly uneconomical, also inapplicable.The tubing that to process retracts the base with car often, and unified processing has been used a large amount of transportations, and wasted a large amount of oil plants; The rig of field work when the tubing thread damage, owing to can not in time process, just must have bigger tubing deposit, satisfies the operate as normal of rig, has caused overstocking of goods and materials; Because be subjected to the restriction of lathe spindle, some tubing screw thread must be finished on the lathe of migrating of heavy caliber main shaft.(probing tubing specification is generally between ∮ 42～219).
The purpose of this utility model provides a kind of special purpose machine tool that adapts to field work, and it can overcome above-mentioned shortcoming effectively.
The utility model is achieved in that drilling tubing is fixed by anchor clamps, and the formation of its screw thread is all finished by the resultant motion of milling cutter.
The utility model is conceived to work piece (probing tubing) and does not rotate, so do not need lathe like that complicated main axle structure and transmission system, no matter and probing tubing diameter, as long as anchor clamps can clamping, can process, and the adjustment of anchor clamps is easy to realize.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.(the pipe internal-threaded example of processing probing)
Fig. 1 is the plane of milling cutter movement locus.n
2Be that milling cutter rotates the movement locus (1450 rev/mins) of (rotation), n at a high speed
1Be the motion rule mark (10～20 rev/min) of milling cutter around work piece center rotation (revolution), work piece and n
1Coaxial, milling cutter is when finishing above-mentioned two kinds of motions, and (vertical with paper) is subjected to displacement vertically, and displacement is decided by the pitch of work piece, just mills out screw thread like this on work piece.
Fig. 2 is a structure chart of the present utility model, work piece (1) is died by anchor clamps (2) and is fixed on the body ［ 13 ］, anchor clamps (2) be one to the leading screw self-centering fixture, certain adjustable range is arranged, after work piece (1) is clamped, starter motor (11) passes through universal coupling (9) through hollow leading screw (6), the internal diameter driving force of main shaft (5) is to milling head (4), make knife bar (3) do the high speed rotation, bent plate (14) is up-down adjustment radially, according to the diameter of work piece, determine the axle center of main shaft (5) and the eccentric distance e value of milling cutter (16) centre of gyration.Because probing tubing screw thread commonly used has only two kinds of pitch, two sections screw threads identical with work piece pitch (special circumstances can be changed hollow leading screw) are arranged on the hollow leading screw (6), screw thread requirement according to work piece, press clasp nut (7) or (8), it is combined with hollow leading screw, turning handle (15), milling cutter (16) just the revolution in, displacement vertically.After the processed moulding of screw thread, milling cutter (16) tends to rest in the machining screw groove, cause the withdrawing difficulty, at this moment, separate clasp nut (7) or (8), handle (15) is turned over an angle (100 °-180 °), and cutter just breaks away from thread groove, by rack-and-pinion (10) cutter is pulled out along straight line.
Fig. 3 is the structure chart of milling head, and two cutter heads (16) are housed on the milling arbor (3), the previous machining screw land that is used for, and back one is used at the bottom of the machining screw silk one-shot forming.Small-bore probing tubing generally is machining internal thread, to externally threaded processing, can lay down knife bar (18), changes cutterhead, and is effectively same.
Claims (2)
1, a kind of lathe that is used to drill the processing of tubing screw thread, this lathe has a flexible jig (1), milling head (4), main shaft (5) and hollow leading screw (6), it is characterized in that the axle center of main shaft and the milling cutter centre of gyration of milling head (4) have an eccentric throw.
2, thread cutting machine according to claim 1 is characterized in that the main shaft (5) and the adjusting range of the centre of gyration eccentric throw of milling head (4) are 2～20 millimeters.
