Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for steel pipe processing, specifically an automatic pipe end oiling device after 3PE pipe end grinding. Background Technology

[0002] 3PE anti-corrosion steel pipe is a type of steel pipe with protective functions, effectively preventing corrosion and oxidation of the pipe surface. During the pipe fitting production process, after each cutting, the ends of the pipe fitting need to be ground to remove any burrs. After grinding, the ends of the pipe fitting need to be coated with oil to achieve rust prevention.

[0003] However, in actual processing, some debris will remain at the grinding location of the pipe fitting after grinding. In order to ensure the effect of subsequent oiling, the workers usually need to clean the grinding location of the pipe fitting before applying oil, which will affect the processing progress and increase the workload of the workers.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0033] Please see Figures 1-8 In this embodiment of the invention, an automatic pipe end oiling device after 3PE pipe end grinding includes a base 1 and a frame 2 rotatably mounted on the base 1, and two cleaning plates 3 and two oil delivery plates 4 are respectively movably provided on both sides of the frame 2.

[0034] The automatic pipe end oiling device after 3PE pipe end grinding also includes:

[0035] A transverse plate 12 is movably mounted on the base 1 and connected to a transverse drive mechanism mounted on the base 1. A ring 5 is movably mounted on the transverse plate 12 via a mounting base 17. A circumferential clamping mechanism for fixing the pipe to be processed is provided on the ring 5.

[0036] A power mechanism is installed on the base 1 to drive the ring 5 to rotate the pipe. The power mechanism is connected to the transverse drive mechanism. A one-way trigger mechanism is also provided between the transverse drive mechanism and the rotation shaft of the frame 2. The one-way trigger mechanism can drive the frame 2 to rotate so that the positions of the cleaning plate 3 and the oil delivery plate 4 are interchanged.

[0037] It should be noted that each of the two cleaning plates 3 is connected to an electric telescopic rod, and similarly, each of the two oil delivery plates 4 is also connected to an electric telescopic rod. The electric telescopic rod is used to drive the two cleaning plates 3 to move closer to each other, so that the two cleaning plates 3 contact the inner wall and outer wall of the pipe respectively. With the help of the rotation of the pipe, the cleaning plates 3 can perform preliminary cleaning of the pipe and the oil delivery plates 4 can perform oiling of the pipe.

[0038] It should be noted that the cleaning plate 3 should be provided with soft cotton material, and the two oil delivery plates 4 are provided with oil holes on opposite sides. Oil is pumped by an external pump body so that the oil can be applied to the inner and outer walls of the pipe.

[0039] Specifically, the working principle of the device is as follows:

[0040] In use, the pipe to be processed is placed in the ring 5, and the pipe is clamped and fixed in the ring 5 by the circumferential clamping mechanism. Then, the power mechanism works in the forward direction, driving the ring 5 to rotate the pipe. The power mechanism also drives the transverse drive mechanism to move. The transverse drive mechanism will drive the transverse plate 12 to move towards the frame 2. After the two cleaning plates 3 are respectively located inside and outside the pipe, the two cleaning plates 3 contact the inner and outer walls of the pipe, thus cleaning the residual debris on the pipe.

[0041] After the cleaning process is completed, the power mechanism reverses its operation, thereby causing the transverse drive mechanism to move the transverse plate 12 away from the frame 2. The one-way triggering mechanism is triggered in the latter part of the stroke of the transverse plate 12, causing the frame 2 to rotate 180°, so that the positions of the cleaning plate 3 and the oil delivery plate 4 are swapped. Then, the power mechanism performs another forward and reverse operation, so that the oil delivery plate 4 applies oil to the pipe.

[0042] In summary, through the cooperation between various mechanisms and components, the two cleaning plates 3 clean the residual debris on the pipes before oiling, preventing the debris from affecting the subsequent oiling effect. This eliminates the need for manual cleaning before oiling, effectively reducing the burden on workers, improving work efficiency, and making it suitable for widespread use.

[0043] Please refer to it again. Figure 4 , Figure 6 as well as Figure 7 The power mechanism includes a rotating shaft 14 rotatably mounted on the base 1, a sleeve 15 rotatably mounted on the transverse plate 12, and a gear 16 fixed to the sleeve 15. A drive motor 13 is also mounted on the base 1, and one end of the rotating shaft 14 is connected to the output end of the drive motor 13. The rotating shaft 14 and the sleeve 15 are slidably fitted together by a limiting structure, and the ring 5 has teeth that mesh with the gear 16. The rotating shaft 14 is connected to the transverse drive mechanism.

[0044] The limiting structure includes two strip-shaped protrusions formed on the outer wall of the rotating shaft 14 and two strip-shaped grooves provided on the inner wall of the sleeve 15. The strip-shaped grooves are adapted to the strip-shaped protrusions, and both are parallel to the central axis of the rotating shaft 14 and the sleeve 15.

[0045] It should be noted that the drive motor 13 is a servo motor with bidirectional output. This application does not make specific limitations on its specific model, and it can be selected according to actual needs.

[0046] During operation, the drive motor 13 drives the rotating shaft 14 to rotate. The rotating shaft 14 then drives the sleeve 15 to rotate through the strip-shaped protrusion and the strip-shaped groove. Consequently, the gear 16 drives the ring body 5 to rotate, causing the pipes located inside the ring body 5 to rotate, ensuring the thoroughness of the cleaning and oiling process.

[0047] Please refer to it again. Figure 5 , Figure 7 as well as Figure 8 The transverse drive mechanism includes a rolling engagement component mounted on the base 1, a sliding engagement structure connected to the rolling engagement component, and a threaded transmission structure connected to the sliding engagement structure, wherein the threaded transmission structure is connected to the rotating shaft 14.

[0048] The threaded transmission structure includes a second lead screw 19 rotatably mounted on the base 1, a threaded sleeve 21 sleeved on the second lead screw 19 and threadedly connected to the second lead screw 19, and a guide sleeve 22 fixedly connected to the threaded sleeve 21. The guide sleeve 22 is slidably connected to a crossbar 20 fixedly mounted on the base 1. The second lead screw 19 is connected to an even-numbered rotating shaft 14 via a first transmission belt 18.

[0049] Two guide plates 11 are fixed on the base 1. The transverse plate 12 is slidably connected to the two guide plates 11, and two limiting strips 34 are fixed on one side of the transverse plate 12, with a gap reserved between the two limiting strips 34. The rolling engagement assembly includes two drive wheels 31 rotatably mounted on the base 1, a connector 32 connecting the two drive wheels 31, and a protrusion 33 provided on the connector 32. The protrusion 33 extends into the gap and is slidably connected to the two limiting strips 34. The connector 32 is in rolling engagement with the two drive wheels 31, and the rotation shaft of one of the drive wheels 31 is connected to the sliding engagement structure.

[0050] The sliding fit structure includes a driven shaft 28 rotatably mounted on the base 1. The driven shaft 28 is provided with a sliding groove, and a drive column 35 is fixed between the threaded sleeve 21 and the guide sleeve 22. The drive column 35 extends into the sliding groove and is slidably connected to the driven shaft 28. The sliding groove includes an inclined section 2801 and a straight section 2802 connected together. The driven shaft 28 is connected to the rotating shaft of the drive wheel 31 through a second bevel gear set 29 and a third transmission belt 30.

[0051] In detail, the second bevel gear set 29 includes a third bevel gear fixed to one end of the driven shaft 28 and a fourth bevel gear rotatably mounted on the base 1, and the third transmission belt 30 is used to connect the rotation shafts of the fourth bevel gear and the drive wheel 31.

[0052] During the process of the drive motor 13 driving the rotating shaft 14 to rotate, the rotating shaft 14 will drive the second lead screw 19 to rotate through the first transmission belt 18. Thus, the crossbar 20 and the guide sleeve 22 act as guides, so that the threaded sleeve 21 moves by engaging with the second lead screw 19 through threaded engagement. Correspondingly, the threaded sleeve 21 will drive the drive column 35 to slide along the groove.

[0053] When the drive column 35 slides along the inclined section 2801, it will cause the driven shaft 28 to rotate. Then, the driven shaft 28 will drive the drive wheel 31 to rotate through the second bevel gear set 29 and the third transmission belt 30.

[0054] Subsequently, the rotation of the drive wheel 31 will cause the connector 32 to drive the protrusion 33 to move. The movement stroke of the protrusion 33 is half of the pattern formed by the connector 32. During this process, the protrusion 33 drives the transverse plate 12 to slide on the two guide plates 11 through the two limiting plates 34, so that the pipe in the ring body 5 reaches a position suitable for cleaning or oiling (i.e. the pipe wall is located between the two cleaning plates 3 or the two oil supply plates 4). When the drive column 35 slides in the straight section 2802, the driven shaft 28 stops rotating, and the transverse plate 12 remains stationary. This process is the process of the cleaning plate 3 or the oil supply plate 4 processing the pipe.

[0055] Please refer to it again. Figure 3 and Figure 5 The one-way triggering mechanism includes a ratchet 24 rotatably mounted on the base 1 and a ratchet plate 23 fixedly mounted on the threaded sleeve 21 and cooperating with the ratchet 24. The rotation shaft of the ratchet 24 is connected to a transmission shaft 26 rotatably mounted on the base 1 via a second transmission belt 25. The transmission shaft 26 is connected to the rotation shaft of the frame 2 via a first bevel gear set 27.

[0056] Furthermore, the first bevel gear set 27 includes a first bevel gear fixedly installed at one end of the transmission shaft 26 and a second bevel gear fixedly installed on the rotating shaft of the frame 2, and the second bevel gear meshes with the first bevel gear.

[0057] It should be noted that during the latter part of the movement of the transverse plate 12 away from the frame 2, the ratchet plate 23 drives the ratchet 24 to rotate. Then, the rotation shaft of the ratchet 24 drives the transmission shaft 26 to rotate through the second transmission belt 25. The transmission shaft 26 then drives the frame 2 to rotate 180° through the first bevel gear set 27, so that the positions of the cleaning plate 3 and the oil delivery plate 4 change, so as to perform different treatments on the pipes and realize automatic switching between the two workstations.

[0058] Please refer to it again. Figure 4 and Figure 6 The circumferential clamping mechanism includes a beveled ring 10 rotatably mounted on the ring body 5, and the beveled ring 10 is connected to a plurality of clamping members equidistantly arranged on the ring body 5 along the circumference;

[0059] The clamping component includes a first lead screw 6 rotatably mounted on the inner wall of the ring body 5, a clamping cylinder 7 sleeved on the first lead screw 6 and threadedly connected to the first lead screw 6, and a bevel gear 9 fixedly mounted on one end of the first lead screw 6 and meshing with the bevel gear ring 10. The clamping cylinder 7 is also fixedly connected with two guide posts 8 slidably disposed on the ring body 5.

[0060] Before processing the pipe fitting, the worker needs to place the pipe fitting to be processed inside the ring body 5. Then, the bevel ring 10 is rotated, and the bevel ring 10 will drive the first lead screw 6 to rotate through the bevel gear 9. Correspondingly, the guide post 8 guides the clamping cylinder 7, so that the clamping cylinder 7 and the first lead screw 6 are threaded together and the ring body 5 moves radially until the end of the clamping cylinder 7 away from the bevel gear 9 clamps the pipe fitting.
