[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] As shown in Figures 1-6, this embodiment of a pipe external thread processing device, the pipe being, for example, a stainless steel pipe, includes a support platform 1, a material rack 2, a feeding structure 3, a clamping structure 4, and an external thread processing structure 5. The material rack 2 is used to place the pipe, the feeding structure 3 is used to receive and feed the pipe that exits from the material rack 2, and after the material is fed to the bottom of the clamping structure 4, the clamping structure 4 first clamps the pipe, and then the external thread processing structure 5 completes the processing of at least one side of the pipe external thread.

[0032] The following sections will describe the support platform 1, the material rack 2, the feeding structure 3, the clamping structure 4, and the external thread processing structure 5 in turn.

[0033] First, as shown in Figures 1 and 3, the support platform 1 has a stepped upper surface with a high surface 11 and a low surface 12. In addition, a discharge port 13 is provided on the support platform 1, which is the outlet after the external thread is processed.

[0034] As shown in Figures 2 and 4, the material rack 2 is set on the support platform 1. Specifically, the material rack 2 is fixed on the high surface 11 by bolts. The material rack 2 consists of two sets of side support components. The side support components include side plates 21. An inclined plate 22 is fixed on the side of the side plate 21 adjacent to the other side support component. A downwardly extending rear baffle 23 is fixed at the bottom of the lowest point of the inclined plate 22. A front baffle 24 is set at intervals on the front side of the rear baffle 23 to form a discharge port. The area between the front baffle 24 and the rear baffle 23 is the discharge area, which is used for the pipe to fall and subsequently fall onto the feeding structure 3.

[0035] It should be noted that the inclination angle of the inclined plate 22 is preferably 30 degrees, and the upper surface of the inclined plate 22 is parallel to that of the side plate 21. In addition, the distance between the upper surface of the inclined plate 22 and the upper surface of the side plate 21 is greater than the diameter of the pipe, so that the side plate 21 can better play the role of blocking.

[0036] Considering the varying lengths of the pipes, in a preferred embodiment, the support component further includes a base plate 25 fixed to the support platform 1. Two sets of slides 26 are fixed on the base plate 25, and a side plate 21 is slidably connected between the outer sides of the two sets of slides 26. It should be noted that the base plate 25 has linearly distributed mounting holes, and a mounting plate 27 is fixed to the outer side of the side plate 21. Hexagonal bolts 28 are fitted on the mounting plate 27 and threadedly connected to the base plate 25 through corresponding mounting holes.

[0037] Thus, when dealing with pipes of different lengths and specifications, the limiting relationship between the hexagonal bolt 28 and the base plate 25 can be released by rotating the hexagonal bolt 28. Then, the position of the side plate 21 on the slide 26 can be adjusted. After the position is adjusted, the hexagonal bolt 28 is aligned with the corresponding mounting hole. Then, the hexagonal bolt 28 can be rotated until it resumes its limiting function.

[0038] As shown in Figure 4, the feeding structure 3 is set on the support platform 1. It includes a telescopic rod 31, a mounting frame 32, and two sets of support bars 33. The telescopic rod 31 is fixed on the support platform 1 by bolts. It is used to allow the support bars 33 to move closer to or away from the clamping structure 4. The mounting frame 32 is assembled on the telescopic end of the telescopic rod 31. The cross-sectional shape of the support bar 33 when viewed from above is L-shaped. The two sets of support bars 33 are detachably connected to both sides of the mounting frame 32 by bolts. A notch is opened on the support bar 33. The notch is initially located directly below the feeding area.

[0039] It should be noted that the diameter of the pipe is greater than the distance between the upper surface of the support bar 33 and the lower surface of the rear baffle 23, and equal to the distance between the notch and the lower surface of the rear baffle 23. In this way, when the front pipe is fed through the feeding structure 3, it is limited by the upper surface of the support bar 33, ensuring that the subsequent pipe will not completely leave the feeding area.

[0040] With this design, when the notch is located directly below the feeding area, it can complete the receiving of a pipe. Subsequently, when the telescopic rod 31 is activated, when the telescopic rod 31 reaches its end, the pipe is fed to the external thread processing structure 5.

[0041] As shown in Figures 1, 2 and 5, the clamping structure 4 includes a support plate 41 set on the support platform 1, which is specifically fixed to the lower surface 12 by bolts. A lifting component is set on the outside of the support plate 41, and the lifting end of the lifting component is equipped with a pneumatic finger 42, whose SMC model is mhz2-16D, which is used to clamp the pipe.

[0042] It should be noted that when the telescopic rod 31 reaches its end, and the pipe is fed to the external thread processing structure 5, the pneumatic finger 42 is located directly above the pipe.

[0043] The lifting component includes an extension plate 43 fixed on a support plate 41. A motor 44 is fixed to the extension plate 43 by bolts. A lead screw 45 is provided at the output end of the motor 44. A nut seat 46 is fitted on the outside of the lead screw 45. A mounting platform 47 is fixed on the outside of the nut seat 46. A pneumatic finger 42 is fixed to the bottom of the mounting platform 47 by bolts.

[0044] It should be noted that two sets of slides 48 are fixed on the side of the support plate 41 near the feeding structure 3, and the nut seat 46 is slidably connected between the outer sides of the two sets of slides 48. In addition, in the preferred design, there are two sets of pneumatic fingers 42 and mounting platform 47, which are symmetrically distributed.

[0045] The external thread processing structure 5 is described as follows: the external thread processing structure 5 includes a slide 3 51 set on the support platform 1, which is specifically fixed to the low surface 12 by bolts. A slide seat 52 is movably set on the outside of the slide 3 51. An external thread processing component is set on the slide seat 52. The external thread processing component includes a support frame 53 fixed on the slide seat 52. A motor 2 54 is assembled on one side of the support frame 53. A turntable 55 is assembled on the output end of the motor 2 54. A processing sleeve 57 is fixed on the side of the turntable 55 away from the motor 2 54 by four sets of outer frames 56. The inner side of the processing sleeve 57 is provided with processing threads for subsequent external thread processing of the pipe.

[0046] In the preferred embodiment, there are four slides 51, and two sets of slide blocks 52 and external thread processing components. Each slide block 52 is slidably connected between the outer sides of the two corresponding sets of slides 51. The external thread processing structure 5 also includes a displacement driving component 58, which is used to move the two sets of slide blocks 52 towards each other or away from each other. The displacement driving component 58 includes an extension platform fixed to the outer side of the support plate 41. A motor 581 is installed on the extension platform by bolts. A gear 582 is fixed to the output end of the motor 581 through a connecting shaft. An extension bar 583 is fixed to the outer side of the slide block 52. Multiple linearly distributed meshing teeth are fixed to the outer side of the extension bar 583. The meshing teeth on the two extension bars 583 are distributed opposite to each other on both sides of the gear 582, and the extension bars 583 mesh with the gear 582 through the meshing teeth.

[0047] In one embodiment, as shown in FIG6, a belt conveyor 6 mounted on the ground is provided below the discharge port 13. The belt conveyor 6 is prior art and is used here to transport the pipe with the external thread processed, which will not be described in detail here.

[0048] The work process is as follows:

[0049] Initially, the material rack 2 contains multiple pipes, which can be replenished manually or mechanically;

[0050] When the telescopic rod 31 is activated, the support bar 33 moves toward the clamping structure 4. During the movement, the first pipe moves synchronously through the notched cavity, while the second pipe is limited by the non-notched cavity on the upper surface of the support bar 33, so the discharge stops. When the telescopic rod 31 reaches the end, the first pipe is fed to the external thread processing structure 5. At this time, the first pipe is located directly below the pneumatic finger 42, and two sets of processing sleeves 57 are distributed on both sides of the first pipe.

[0051] Start motor 44 to make lead screw 45 work, while nut seat 46 and pneumatic finger 42 will descend. When the first pipe is in the clamping area of ​​pneumatic finger 42, the pneumatic finger 42 is used to clamp it and lock and limit the first pipe.

[0052] Subsequently, motor 2 54 and motor 3 581 are started. When motor 3 581 is working, gear 582 rotates. Under the transmission action of meshing teeth, the two sets of extension bars 583 move towards each other. The two sets of slides 52 and processing sleeve 57 will also move towards each other, that is, towards the first pipe. When motor 2 54 is started, turntable 55 drives processing sleeve 57 to rotate, so that processing sleeve 57 completes the external thread processing on both sides of the first pipe.

[0053] Finally, using motor 2 54 and motor 3 581, the processing sleeve 57 is returned to its original position. First, using motor 1 44, the first pipe that has been clamped and whose external thread has been processed is raised, thus disengaging from the notch. Using the telescopic rod 31 to retract, the support bar 33 returns to its original position and reconnects to the second steel pipe through the notch. Then, motor 1 44 is started again, and the first pipe that has been clamped and whose external thread has been processed is lowered to the discharge port 13. The pneumatic finger 42 is released from its limit, and the first pipe that has been processed with external thread is unloaded and transported by the belt conveyor 6. The second and subsequent pipes can be processed in the same way.

[0054] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
