Then the slag inside the pipe body is blown out through the slag removal assembly 330, so as to avoid the influence of the impurities on the subsequent processing and use process. Next, the threaded part is polished through the polishing mechanism 400 and the burr on the edge of the waist hole 610 is removed through the deburring mechanism 500, thereby realizing the finishing process of the waist hole 610 of the threaded pipe 600.

[0039] Three table bodies 100 are specifically provided in the embodiment, and a heating station, a polishing station and a deburring station are sequentially arranged on the three table bodies 100, so as to provide different processing for the threaded pipe 600 to be processed. Further, the threaded pipe 600 in the embodiment is transferred by an external moving device, which is preferably a mechanical hand (not shown in the figure). When carrying, the whole threaded pipe 600 is transferred by clamping and fixing the middle section of the threaded pipe 600.

[0040] Referring to Figures 2 to 4As shown, in the embodiment, at least one supporting assembly 230 is included in the heating station, the polishing station and the deburring station to support and limit the pipe body of the threaded pipe 600. On the one hand, it can improve the stability of the threaded pipe 600 in the machining process and avoid the collapse and bending of the middle part of the pipe body under the action of gravity. On the other hand, it can also assist the pipe body to rotate around its axis. Specifically, the supporting assembly 230 in the embodiment includes a jacking drive 231, a lifting frame 235, two moving plates 233 and a plurality of fixed wheels 232. The lifting frame 235 is connected to the working end of the jacking drive 231 and is lifted and moved below the threaded pipe 600 to be machined by the jacking drive 231. The lifting frame 235 extends along the width direction of the threaded pipe 600 to be machined. Two jacking wheels 236 are arranged at the ends of the lifting frame 235. Two moving plates 233 are arranged corresponding to the two jacking wheels 236. The moving plate 233 is provided with an inclined surface extending upward from the bottom end and gradually away from the threaded pipe 600 to be machined. The inclined surface is supported on the corresponding jacking wheel 236 and moves towards / away from the threaded pipe 600 to be machined by the jacking wheel 236. A plurality of fixed wheels 232 are symmetrically arranged on the two moving plates 233 and move synchronously with the moving plates 233 to clamp / release the threaded pipe 600 to be machined. Further, the supporting assembly 230 further includes a bracket 237, a translation module 234 and a buffer reset member 238. The bracket 237 is arranged on the table body 100. The translation module 234 extends along the width direction of the threaded pipe 600 to be machined. The two moving plates 233 are respectively slidably connected to the translation module 234. The buffer reset member 238 is arranged between the two moving plates 233.

[0041] The process of the supporting assembly 230 will be introduced as follows: Before use, the moving plate 233 is at the lowest point, at which time the interval distance of the two moving plates 233 in the width direction of the threaded pipe 600 is the farthest, so that the threaded pipe 600 can smoothly enter between the two moving plates 233. Then the jacking drive 231 drives the lifting frame 235 and the jacking wheel 236 thereon to rise synchronously, and the moving plate 233 gradually approaches by the inclined surface of the moving plate 233 while rising, until the fixed wheel 232 on the moving plate 233 clamps and fixes the threaded pipe 600 thereon. During rotation, the fixed wheel 232 can assist the pipe body of the threaded pipe 600 to rotate, thereby reducing the friction between the threaded pipe 600 and the moving plate 233, protecting the threaded pipe 600 and improving the rotation driving efficiency. When the threaded pipe 600 needs to be released, the jacking drive 231 stops working, and the two moving plates 233 can return to the initial position under the action of the buffer reset member 238, waiting for the next fixing and supporting.

[0042] In the embodiment, the threaded pipe 600 needs to be supported and fixed during the processing, and the threaded pipe 600 is in a rotating state, therefore, in the embodiment, the base positioning assembly 210 and the pipe body rotating driving assembly 220 are arranged in the heating station, the polishing station and the deburring station, Figure 5 The pipe body rotating driving assembly 220 and the base positioning assembly 210 in the heating station and the polishing station are shown, in the embodiment, the base positioning assembly 210 is arranged corresponding to the base 620 of the threaded pipe 600 to be processed, and the base positioning assembly 210 includes a plurality of positioning plates 211, the plurality of positioning plates 211 surround at least one limiting clamping groove 212, the base 620 of the threaded pipe 600 to be processed is embedded in the at least one limiting clamping groove 212, based on this, the base 620 of the pipe body can be embedded in the limiting clamping groove 212 at a fixed angle, so that the initial processing position of the threaded pipe 600 can be fixed, and the processing precision and the stability of the processing quality are improved. Further, in the embodiment, the pipe body rotating driving assembly 220 that can drive the base positioning assembly 210 to rotate synchronously is arranged corresponding to the heating station and the polishing station, the pipe body rotating driving assembly 220 includes a rotating motor 221, and the base positioning assembly 210 is connected to the working end of the rotating motor 221, so as to provide driving effect for the rotation of the threaded pipe 600.

[0043] Referring to Figure 6 As shown in the figure, the heating mechanism 300 of the embodiment is provided with two heating assemblies 310, which can achieve the purposes of removing impurities on the surface of the pipe body and reducing the rigidity of the pipe body after heating towards the threaded part, so as to improve the quality of subsequent polishing processing. Specifically, any heating assembly 310 in the embodiment includes a heat source 311, at least one spray head 312 and at least one heat conducting pipe 313, the heat source 311 is preferably a flame spray gun, the spray head 312 is connected with the heat source 311 through the corresponding heat conducting pipe 313, and the spray head 312 is arranged towards the waist hole 610 of the threaded pipe 600 to be processed.

[0044] Further, in order to improve the machining stability and ensure the heating effect, the temperature detection assembly 320 is arranged on one side of the heating assembly 310 in the embodiment, which comprises a temperature detector 321 and an adjusting frame 322, the working end of the temperature detector 321 is arranged at the waist hole 610 of the threaded pipe 600 to be machined, and the temperature detector 321 moves around the threaded pipe 600 to be machined through the adjusting frame 322. Further, the temperature detector 321 in the embodiment is preferably an infrared temperature detector, and the operator can observe whether the heating assembly 310 effectively heats the waist hole 610 of the threaded pipe 600 through the temperature detector 321. Still further, the temperature detector 321 in the embodiment can adjust the detection site through the adjusting frame 322, so that it can be applied to pipes of different models or sizes.

[0045] It is worth noting that after heating, impurities attached to the pipe body and doped elements inside the pipe body will accumulate on the surface to form zinc slag and other impurities. If the above impurities fall into the pipe body, not only will it affect the cleanliness of the fluid during subsequent use, but also will increase the possibility of pipe body corrosion, thereby greatly shortening the service life of the pipe body. Therefore, the slag removal assembly 330 is arranged in the embodiment to blow and remove the zinc slag and other impurities generated after heating, so as to ensure the cleanliness inside the pipe body. Specifically, the slag removal assembly 330 in the embodiment further comprises a mounting plate 333 and a connecting pipe 332, the mounting plate 333 is arranged between the threaded pipe 600 to be machined and the gas supply part 331, one end of the connecting pipe 332 is connected to the mounting plate 333, and the other end penetrates the pipe body inside the threaded pipe 600 to be machined. The gas supply pipe can move towards the connecting pipe 332 to communicate with the connecting pipe 332.

[0046] Referring to Figure 7 and Figure 8As shown, the polishing mechanism 400 in the embodiment polishes the surface of the threaded part and the waist hole 610 by means of the polishing roller 410, which comprises a roller driver 420 and a first sliding seat 440, the first sliding seat 440 being slidingly connected to the first adjusting module 430, the roller driver 420 being arranged on the first sliding seat 440, and the polishing roller 410 being covered with a brush and connected to the working end of the roller driver 420. Based on this, during the polishing process, the polishing roller 410 is in a high-speed rotating state and can move along the first adjusting module 430, and the threaded pipe 600 to be processed can rotate around its own axis, thereby greatly improving the efficiency and uniformity of the polishing process. Specifically, the roller driver 420 in the embodiment is preferably a rotary motor 221, which can also be arranged as other structures or devices capable of driving the polishing roller 410 to rotate in different embodiments, and the present application does not make specific limitations on this. In addition, the support rotating mechanism 200 in the polishing mechanism 400 is arranged in the same way as the support rotating mechanism 200 in the heating station, which will not be described in detail here.

[0047] Referring to Figure 9 As shown, in the deburring station, the embodiment provides another structure of the pipe rotating drive assembly 220, which is clamped on the pipe body of the threaded pipe 600, thereby being capable of synchronously driving the pipe body to rotate from the middle to both ends, and at the same time playing a supporting effect on the pipe body. Compared with the pipe rotating drive assembly 220 in the heating station or the polishing station, the pipe rotating drive assembly 220 in the deburring station has the effects of higher efficiency, faster corresponding speed, and auxiliary support of the pipe body, and the specific structure is as follows: the pipe rotating drive assembly 220 comprises a rotary motor 221, a transmission belt 223, and a plurality of transmission wheels 222, the threaded pipe 600 to be processed is clamped between the plurality of transmission wheels 222, at least one transmission wheel 222 is connected to the working end of the rotary motor 221, and the plurality of transmission wheels 222 are connected by the transmission belt 223.

In this embodiment, the edge polishing assembly 540 is inserted into the waist hole 610 and polished along the inner wall of the waist hole 610, and then withdrawn from the waist hole 610. At this time, the burr detection assembly performs infrared detection on the inside of the waist hole 610 through the infrared detector 570 to judge the deburring effect.

[0057] It is worth noting that in steps S1 to S4, the pipe body of the threaded pipe to be processed 600 is supported in the support assembly 230, and a plurality of rotation support points are formed on the pipe body by the fixed wheel 232, and the bottom disc 620 is placed in the bottom disc positioning assembly 210 to limit the placement angle of the threaded pipe to be processed 600; in steps S1 to S4, the threaded pipe to be processed 600 is moved between the heating station, the polishing station and the deburring station by an external moving device. The external moving device includes but is not limited to a crane, a robot, a carrying robot, etc.

[0058] The threaded pipe waist hole processing equipment and method provided by the application fixes the threaded pipe to be processed 600 in the corresponding station through the support rotating mechanism 200, providing a stable working platform for the subsequent processing process, and heating the waist hole 610 of the threaded pipe 600 through the heating mechanism 300, thereby reducing the hardness of the corresponding part and removing the impurities on the surface of the threaded pipe 600. Then, the zinc slag and other impurities inside the pipe body are blown out by the slag removal assembly 330, avoiding the influence of impurities on the subsequent processing and use process. Next, the threaded part is polished by the polishing mechanism 400 and the burr on the edge of the waist hole 610 is removed by the deburring mechanism 500, thereby realizing the finishing process of the waist hole 610 of the threaded pipe 600. The above processing can avoid the problems of poor assembly, affecting the processing safety, disturbing the fluid and affecting the overall appearance caused by the burr on the waist hole 610 in the conventional use process, and has significant advantages in assembly and use compared with the conventional technology at present.
