Next, the operation of this device will be described. First, the hydraulically actuated sill 30 is set to the retracted position, and the distal end of the pipe fitting C screwed onto the threaded pipe P is transferred to a predetermined position by a transfer mechanism (not shown). The movable base 2 is advanced by the cylinder mechanism 3, and the nozzle head 5B and brushes 76, 77.78 are inserted into the pipe joint C, and the movement of the movable base 2 is performed under the control of the limit switch 10.11. . Subsequently, the motor 40 is started and its driving force is transmitted to the gear 44 via the reduction gear 41, the output shaft 42, and the gear 43. gear 4
4 rotates together with a guide disk 45 while being supported by a guide roller 46, and a planetary gear 48 supported by the guide disk 45 by a shaft 47 also makes a planetary motion around the sun gear 50, and the rotating cylinder 55 and nozzle Rotate the head 56. In this case, since the rotary joint 54 is interposed between the rotary cylinder 55 and the support cylinder 51, the support cylinder 51 is connected to the rotary cylinder 55.
is fixed with respect to its rotation. Here, if the support tube 51 is eccentric from the axis of the gear 44, the rotating tube 55 and the nozzle head 56 will revolve along the inner surface of the pipe grip C as shown by arrow A in FIG. , also to the nozzle rad 5
6 rotates as shown by arrow B.

Next, grease of a predetermined standard is supplied from a grease supply device (not shown) to the grease supply port 52 of the support cylinder 51 at a pressure of, for example, 30 kg/cts2, and the grease is supplied to the nozzle head 56.
Grease G is blown out from the tip of the short tube 61 through the center hole 59 as shown in FIG. At the same time, if compressed gas of, for example, 2 to 4 kg/cm2 is supplied from a compressed gas supply device (not shown) to the gas supply port 53 of the support cylinder 51,
This compressed gas passes through the annular space 60 between the inner pipe 57 and the outer pipe 58, passes through the outer surface of the short pipe 61, and is blown out from the gas outlet 62 as a gas flow surrounding the grease G. The blown compressed gas spreads outward due to a pressure drop, and the grease G is blown out at an angle. Therefore,
By selecting the gas pressure value, the spread angle of the grease G from the short pipe 61 can be set to a desired value.

そして、ノズルへラド56は管継手Cの内面に沿って移
動するのでグリースGは内面に附着されることになる。
Then, since the nozzle rad 56 moves along the inner surface of the pipe joint C, the grease G is deposited on the inner surface.

At this time, if the cylinder mechanism 3 is actuated to reciprocate the movable table 2 by a predetermined distance, the grease G can be evenly applied to the threaded portion of the inner surface of the pipe joint C by the brushes 76 and 77. When the short pipe 61 comes out of the pipe joint C, the blown out grease G adheres to the inner surface of the cover 24 and flows down into the oil sump 25 where it is collected and reused. The brushes 76 and 77 serve to even out the applied grease G, but
If the inner diameter of the pipe to be greased is an appropriate size for the diameter of the brushes 76 and 77, there is no need to eccentrically position the Rad 56 to the nozzle. If the brush cannot be inserted into the
Remove the rad 5 from the nozzle using the brush 78 at the tip.
All you have to do is smooth out the grease when you return in step 6.

The compressed gas flow determines the spread of the grease G, but also plays a role in preventing grease from clogging. That is, by blowing out compressed gas for a short time even after the grease spraying has stopped, the grease remaining in the short pipe 61 is sucked and blown away, thereby preventing the grease from dripping.

The nozzle head 56 is moved forward and backward by the movable base 2 using the pipe joint C.
The threaded pipe P may be made to move forward or backward, and the internal threading section is not necessarily limited to pipe fittings, but can also be applied to cases in which threading is performed directly on the inner surface of the pipe. Of course.

[Scope of Claims] 1. A nozzle head that enters the tube end and sprays lubricant onto the threaded portion on the inner surface, a mechanism that moves the nozzle head back and forth in the axial direction relative to the tube end, and the nozzle. An eccentric adjustment mechanism that eccentrically shifts the head from the axis according to the inner diameter of the tube end;
A lubricant application device for a threaded portion on an inner surface of a tube, comprising a planetary movement mechanism that causes the eccentric nozzle head to rotate and revolve along the inner surface of the tube end. 2. The device for applying lubricant to a threaded portion on an inner surface of a tube according to claim 1, wherein the eccentricity adjustment mechanism moves a support shaft connected to the nozzle head along an eccentricity curved hole. 3. The planetary motion mechanism includes a large-diameter internal gear centered on the axis, a sun gear disposed around the support shaft, and is interposed between the internal gear and the sun gear to transmit driving force. A device for applying lubricant to a threaded portion on an inner surface of a tube according to claim 3, comprising a planetary gear. 4. The device for applying lubricant to a threaded portion on an inner surface of a tube according to claim 1, wherein a brush is attached near the nozzle and coaxially with the nozzle to even out the lubricant applied to the threaded portion. 5. The device for applying lubricant to a threaded portion on an inner surface of a tube according to claim 4, wherein the brush is disposed around the nozzle head and is removable. 6. The lubricant application device for a threaded portion on an inner surface of a pipe according to claim 1, wherein compressed gas is blown out from the nozzle head in conjunction with the spraying of the lubricant.
