The utility model relates to a coupling screwing machine, in particular to a device for automatically coating lubricating grease on the internal thread of a coupling, which comprises a main shaft (3), a motor (15) and an oil throwing head (1). The oil throwing head (1) is positioned at the front end of the main shaft (3) and is connected with the main shaft (3) integrally, the main shaft (3) is a hollow structure in which an oil pipe (4) is arranged, the front end of the oil pipe (4) is positioned in the inner chamber of the oil throwing head and the front end surface of the oil pipe (4) is closed, one or more holes are formed on the front end wall of the oil pipe along a radial direction, the rear end of the oil pipe (4) is communicated with an oil supply system via an oil distributing valve (11), a valve core (12) is arranged in the oil distributing valve (11), and a driving belt wheel (8) connected on the main shaft (3) is connected with a driving belt wheel (14) driven by a motor (15) through a belt (9). The device of the utility model uses the motor to drive the oil throwing head to coat lubricating grease on the internal thread of the coupling, reduces labor forces, is stead in operation, and can uniformly coat the grease and accurately control coating amounts.
Description
Technical field
The utility model relates to the box cupling screw-on machine, relates generally to the device that a kind of box cupling internal thread is coated with lubricant grease automatically.
Background technique
The two ends car that box cupling is is female than short steel pipes, and internal thread establishing criteria or standard have round thread, trapezoidal thread, special trapezoidal thread etc., has the tapering of 1:16 usually, is used for having corresponding externally threaded long steel pipe to couple together in the two ends car.Typical oilfield with seamless steel pipe before dispatching from the factory with an end of the steel pipe box cupling of screwing on, the other end only adds protecting jacket to screw thread.When dig a well in the oil field, this end screw thread is screwed in the box cupling of root steel pipe, is in turn connected to form oil-well wall.The preparatory screw-on machine of box cupling is the equipment that box cupling is screwed into fast steel pipe, and box cupling (master) screw-on machine is after box cupling and steel pipe are twisted in advance, by the moment of torsion of regulation box cupling and steel pipe is tightened the equipment with the intensity that reaches expection again.For protection box cupling and steel pipe screw thread twist when connecing not impaired; Need to be coated with lubricant grease for the box cupling internal thread before connecing twisting, but generally adopt the artificial mode that is coated with lubricating grease in the existing technology, smear problems such as inhomogeneous, waste but this mode of smearing need increase manual work and existence; Quality is low, and cost is high.
Summary of the invention
For solving the problems of the technologies described above, the purpose of the utility model provides the device that a kind of box cupling internal thread is coated with lubricant grease automatically.
The utility model adopts following technological scheme for accomplishing the foregoing invention task:
A kind of box cupling internal thread is coated with the device of lubricant grease automatically, mainly comprises main shaft, motor and gets rid of oily head; The described oil head that gets rid of is positioned at the front end of main shaft and connects one with main shaft; Described main shaft is the hollow-core construction that is built-in with oil pipe, and the front end of said oil pipe is positioned at the inner chamber and the front-end face sealing of getting rid of the oil head, on the oil pipe front bulkhead, radially has one or more holes; The rear end of described oil pipe is connected with oil supply system through oil distributing valve, and in described oil distributing valve, has the spool in order to control lubricant grease amount size; The drive pulley that connects on the described main shaft is connected with drive pulley by driven by motor through belt.
A kind of box cupling internal thread that the utility model proposes is coated with the device of lubricant grease automatically, adopts driven by motor to get rid of the oil head and is coated with lubricant grease for the box cupling internal thread, reduce artificial, have oiling evenly, running is steady and be coated with the characteristics that oil mass can accurately be controlled.
