Example

[0026] Reference Figure 1-Figure 4 This embodiment provides an internal thread copper pipe thread oiling device, including a machine 1 and a grease gun 2. The grease gun 2 is an automatic grease gun 2. In order to facilitate the introduction of oil into the internal thread, the output end of the grease gun 2 has a horizontal part, and an inclined part facing the internal thread is provided at the tail of the horizontal part, and the inclined part is closer to the internal thread copper pipe, and the inclined part is inclined downward;

[0027] It also includes a clamp 3 arranged on the top of the machine 1 and a translation mechanism 4 arranged on the top of the machine 1, wherein the clamp 3 adopts a three-jaw chuck, and the translation mechanism 4 includes an electric telescopic rod fixedly connected to the machine 1; the clamp 3 is used to clamp the internal thread copper tube, the translation mechanism 4 is on the side of the clamp 3, the output end of the translation mechanism 4 is a translation plate 5, and the telescopic end of the electric telescopic rod is connected to the translation plate 5. In order to improve the stability of the translation plate 5, a guide rail 6 is also fixed on the top of the machine 1, and the translation plate 5 is slidably connected to the guide rail 6, and the moving direction of the translation plate 5 is parallel to the axial direction of the internal thread copper tube;

[0028] A vertical plate 7 is provided on the translation plate 5, and the vertical plate 7 is slidably connected to the translation plate 5, and the sliding direction of the vertical plate 7 is the vertical direction, and the relative position of the vertical plate 7 and the translation plate 5 is fixed by a locking member 8, and the locking member 8 is a screw, and the vertical plate 7 is slidably connected to the translation plate 5, so that the grease gun 2 can be adjusted to a suitable position more quickly, and the installation is more convenient; the vertical plate 7 is provided with a positioning mechanism, and the positioning mechanism is located on the side of the clamp 3, and the grease gun 2 is installed on the output end of the positioning mechanism, and the positioning mechanism is used to move the grease gun 2, and move the grease end from the outside of the internal threaded tube to the internal thread of the internal threaded copper tube;

[0029] When in use, the internally threaded copper tube is clamped on the fixture 3, and the axial direction of the internally threaded copper tube is parallel to the moving direction of the translation plate 5, then the locking piece 8 is loosened, and the relative position of the vertical plate 7 and the translation plate 5 is adjusted so that the horizontal part is roughly at the middle height of the internally threaded tube, and then the locking piece 8 is closed to lock the position of the vertical plate 7 and the translation plate 5, and then the positioning mechanism is operated to move the grease gun 2. During this process, the grease gun 2 first moves horizontally so that the horizontal part and the inclined part move to the inside of the internally threaded copper tube, and then the grease gun 2 is moved in Move vertically downward to make the end of the inclined part gradually approach the internal thread; then turn on the grease gun 2 to grease the internal thread, and at the same time turn on the translation mechanism 4 to make the translation mechanism 4, the grease gun 2, etc. away from the internal thread copper tube, and at the same time operate the clamp 3 to drive the internal thread copper tube to rotate, and the grease gun 2 moves while injecting oil, and the internal thread copper tube rotates. In summary, the internal thread of the internal thread copper tube is evenly oiled. When the inclined part is completely moved out of the internal thread copper tube, the positioning mechanism and the translation mechanism 4 are operated to reset the grease gun 2.

[0030] As a preferred embodiment of the present invention, refer to Figure 2-Figure 4The positioning mechanism includes a through hole opened on the vertical plate 7, the through hole includes a horizontal section 9 and a vertical section 10, one end of the horizontal section 9 is connected to one end of the vertical section 10, and the vertical section 10 is between the horizontal section 9 and the clamp 3, the horizontal section 9 is parallel to the axis direction of the clamped internal threaded copper tube, and the connecting part of the horizontal section 9 and the vertical section 10 is chamfered. The chamfering process forms a smoothly transitioned arc surface at the connection between the horizontal section 9 and the vertical section 10, avoiding the existence of right-angled edges, reducing stress concentration, and avoiding unnecessary stress impact or wear when the moving shaft 11 slides;

[0031] The positioning mechanism further includes a moving shaft 11 passing through the through hole, the moving shaft 11 is installed with a rolling part 12, the rolling part 12 is a bearing, and the bearing greatly reduces the movement resistance of the moving shaft 11 in the through hole; the grease gun 2 is installed on one end of the moving shaft 11, more specifically, a base plate 13 is fixed to one end of the moving shaft 11, and the grease gun 2 is fixed on the base plate 13; the positioning mechanism further includes a power mechanism for driving the moving shaft 11 to move along the through hole, and when the grease gun 2 is in a parked state, the moving shaft 11 is at one end of the horizontal section 9 away from the vertical section 10;

[0032] The power mechanism includes a driving member 14, one end of which is rotatably connected to the vertical plate 7. More specifically, the driving member 14 is a long rod. The vertical plate 7 is rotatably connected to a rotating shaft 15, and the rotating shaft 15 is located in the middle and lower part of the horizontal section 9. The rotating shaft 15 is fixedly connected to one end of the driving member 14; the other end of the driving member 14 is slidably connected to the other end of the moving shaft 11. More specifically, the driving member 14 is provided with an elongated hole 16, and the moving shaft 11 passes through the elongated hole 16. The power mechanism also includes a power unit 17 for rotating the driving member 14, and the power unit 17 adopts a servo motor;

[0033] When in use, Figure 3 In the state shown, the power unit 17 is turned on to rotate the rotating shaft 15 and the driving member 14 around the axis of the rotating shaft 15. Since the movable shaft 11 passes through the long strip hole 16 on the driving member 14, and the rotating shaft 15 is located in the middle and lower part of the horizontal section 9, and the movable shaft 11 passes through the through hole, when the driving member 14 rotates, it can push the movable shaft 11 and the grease gun 2 to move along the horizontal section 9 and the vertical section 10. When moving on the horizontal section 9, the grease gun 2 moves in the horizontal direction, so that the horizontal part and the inclined part at the output end of the grease gun 2 enter the inner thread of the copper tube from the middle part of the internal thread. When moving on the vertical section 10, the grease gun 2 moves in the vertical direction, so that the inclined part gradually approaches the internal thread. When the movable shaft 11 reaches the end of the vertical section 10 away from the horizontal section 9, the distance between the oil outlet end of the inclined part and the internal thread is very small, so that the oil can be better attached to the internal thread.

[0034] As a preferred solution of the utility model, the positioning mechanism also includes a track 18 fixed to one side of the vertical plate 7, the track 18 is slidably connected to a slider 19, the slider 19 is fixedly connected to a track 20, and the track 20 is slidably connected to a slider 21;

[0035] The moving shaft 11 is fixedly connected to the second slider 21, and a key is installed between the moving shaft 11 and the second slider 21 to prevent the moving shaft 11 and the second slider 21 from rotating relative to each other;

[0036] When in use, the purpose of setting track 18, slider 19, track 20 and slider 21 is to limit the angle of the grease gun 2 to prevent its angle from changing during movement. When the grease gun 2 moves, the slider 2 drives the slider 21 to move. Since the track 18 is slidably connected to the slider 19, the slider 19 is fixedly connected to the track 20, and the track 20 is slidably connected to the slider 21, the slider 21 can only slide relative to the track 18 and the track 20, and the slider 21 cannot rotate, so the grease gun 2 will not rotate.

[0037] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
