[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The threading machine with processing and positioning functions offers two technical solutions:

[0024] The first embodiment includes a workbench 1 and a threading mechanism 2. Support legs 3 are fixedly connected to the four corners of the bottom of the workbench 1. An automatic positioning mechanism is provided above the workbench 1. The automatic positioning mechanism includes a clamping and measuring component 4, a lifting component 6 and a shaft measuring component 7.

[0025] The clamping and measuring assembly 4 includes a support platform 41, on which two sets of symmetrical clamping structures are provided. The clamping structures include two arc-shaped clamping plates 44 on the left and right, and laser range sensors 46 are provided on the arc-shaped clamping plates 44. When the two arc-shaped clamping plates 44 clamp and center the pipe to be processed, the radius of the pipe is measured by the laser range sensors 46. The clamping structure also includes two sets of fixed seats 42 on the front and rear. Each set of fixed seats 42 consists of two fixed seats 42 on the left and right. A slide rod 43 is fixedly connected between each set of fixed seats 42. The two arc-shaped clamping plates 44 are slidably connected to the two sides of the surfaces of the two slide rods 43. Limiting springs 45 are sleeved on the surfaces of the slide rods 43 on the opposite sides of the two arc-shaped clamping plates 44. The laser range sensor 46 is fixedly connected to the outside of the right arc-shaped clamping plate 44 through a bracket. A measuring baffle 47 for cooperating with the laser range sensor 46 is fixedly connected to the top of the support platform 41.

[0026] When threading pipes, the pipes are clamped by the clamping and measuring component 4, which is applicable to pipes of different diameters. At the same time, the radius of the pipe to be processed is detected by the laser range sensor 46, which facilitates subsequent axis positioning.

[0027] The second embodiment differs from the first embodiment in that: the axis measuring component 7 includes an axis measuring sensor 78, which, after obtaining the pipe radius data, moves to the same straight line as the pipe axis and, with the cooperation of the lifting component 6, aligns the pipe axis with the threading mechanism 2. The axis measuring component 7 includes a fixing plate 71, which is fixedly connected to the outer side of the left arc-shaped clamping plate 44. A middle rod 72 is fixedly connected between the top and bottom of the inner wall of the fixing plate 71. A support plate 73 is rotatably connected to the surface of the middle rod 72. A torsion spring 74 is sleeved on the surface of the middle rod 72 inside the support plate 73. One end of the torsion spring 74 is fixedly connected to the surface of the middle rod 72. The other end is fixedly connected to the support plate 73. A limit plate 75 is fixedly connected to the left side of the front of the support plate 73, and the limit plate 75 is used to limit the rotation angle of the support plate 73. A slide rail 76 is fixedly connected to the back of the support plate 73, and a support frame 77 is slidably connected to the surface of the slide rail 76. An axis measuring sensor 78 is fixedly connected to the back of the support frame 77. A drive motor 79 is fixedly connected to the front of the support frame 77, and a drive gear 710 is fixedly connected to the output end of the drive motor 79. The drive motor 79 is a servo motor, and a signal processor is set on the servo motor to process the signal of the laser rangefinder 46. A rack 711 is fixedly connected to the back of the support plate 73, and the drive gear 710 meshes with the rack 711 for transmission.

[0028] The lifting assembly 6 cooperates with the axis measuring assembly 7. The lifting assembly 6 includes a T-shaped guide rod 61, which is slidably connected to the top of the worktable 1. The top of the T-shaped guide rod 61 is fixedly connected to the bottom of the support platform 41. A hydraulic cylinder 62 is fixedly connected to the bottom of the worktable 1, and the telescopic end of the hydraulic cylinder 62 is fixedly connected to the bottom of the support platform 41.

[0029] The axis measuring component 7 moves the axis measuring sensor 78 to the center of the pipe based on the radius data, and the lifting component 6 aligns the axis of the pipe with the center of the threading mechanism 2.

[0030] In use, the pipe to be processed is pressed in from above the two arc-shaped clamps 44. During pressing, the two arc-shaped clamps 44 are moved away from each other. After the pipe enters the middle part of the arc-shaped clamps 44, the two limit springs 45 clamp the two arc-shaped clamps 44 to both sides of the pipe. After stabilization, the distance moved by the arc-shaped clamps 44 is measured by the cooperation of the laser range sensor 46 and the measuring baffle 47. The distance moved by the arc-shaped clamps 44 is the radius of the clamped pipe. The radius data is transmitted to the axis measuring component 7, and the drive motor 79 is started at the same time. The drive motor 79 operates and drives the drive gear 710 to rotate. The drive gear 710 rotates and engages with the rack 711, causing the rack 711 to move. This, in turn, moves the shaft center measuring sensor 78 to the shaft center of the pipe. The hydraulic cylinder 62 is activated, causing the support platform 41 to move. The movement stops after the shaft center measuring sensor 78 detects that it is aligned with the center of the threading mechanism 2. At this time, the positioning is automatically completed. The pipe is pushed into the threading mechanism 2. When the pipe contacts the support plate 73, it pushes the support plate 73 to rotate, allowing the pipe to pass over the support plate 73.
