[0038] The threaded pipe waist hole processing equipment described in this embodiment fixes the threaded pipe 600 to be processed in the corresponding workstation through the supporting rotating mechanism 200, providing a stable working platform for the subsequent processing process, and at the same time heats the waist hole 610 of the threaded pipe 600 through the heating mechanism 300, thereby reducing the hardness of the corresponding part and removing impurities on the surface of the threaded pipe 600, and then blows out zinc slag and other impurities inside the pipe body through the slag removal component 330 to avoid the influence of impurities on the subsequent processing and use process, and then grinds the threaded part through the grinding mechanism 400 and removes the burrs on the edge of the waist hole 610 through the deburring mechanism 500, thereby realizing the fine processing process of the waist hole 610 of the threaded pipe 600. After the above processing, the problems such as poor assembly caused by the burrs at the waist hole 610 during conventional use, affecting the processing safety, interfering with the fluid and affecting the overall appearance can be avoided. Compared with the conventional technology at this stage, there are significant advantages in both assembly and use.

[0039] In this embodiment, three platforms 100 are specifically provided, and heating stations, grinding stations and deburring stations are provided on the three platforms 100 in sequence, so as to provide different processing for the threaded pipe 600 to be processed. Furthermore, the threaded pipe 600 in this embodiment is transferred by an external mobile device, which is preferably a robot (not shown in the figure), and the middle section of the threaded pipe 600 is clamped and fixed to transfer the entirety during transportation.

[0040] See also Figures 2 to 4As shown, in this embodiment, at least one support assembly 230 is included in the heating station, the grinding station and the deburring station, which is used to support and limit the tube body of the threaded tube 600. On the one hand, it can improve the stability of the threaded tube 600 in each processing process and avoid the collapse and bending of the middle part of the tube body under the action of gravity. On the other hand, it can also assist the tube body to rotate around its axial direction. Specifically, the support assembly 230 in this embodiment includes a lifting drive 231, a lifting frame 235, two movable plates 233 and a plurality of fixed wheels 232, wherein the lifting frame 235 is connected to the working end of the lifting drive 231, and is lifted and lowered below the threaded pipe 600 to be processed by the lifting drive 231, the lifting frame 235 extends along the width direction of the threaded pipe 600 to be processed, two pushing wheels 236 are arranged at both ends of the lifting frame 235, and the two movable plates 233 are arranged corresponding to the two pushing wheels 236, wherein the movable plate 233 is provided with an inclined surface extending from its bottom end upward gradually away from the threaded pipe 600 to be processed, the inclined surface is supported on the corresponding pushing wheel 236, and moves toward / away from the threaded pipe 600 to be processed by the pushing wheel 236, and the plurality of fixed wheels 232 are symmetrically arranged on the two movable plates 233, and move synchronously with the movable plates 233 to clamp / release the threaded pipe 600 to be processed. Furthermore, the support assembly 230 also includes a bracket 237, a translation module 234 and a buffer reset member 238, the bracket 237 is arranged on the platform 100, the translation module 234 extends along the width direction of the threaded tube 600 to be processed, the two movable plates 233 are respectively slidably connected to the translation module 234, and the buffer reset member 238 is arranged between the two movable plates 233.

[0041] The following is an introduction to the movement process of the support assembly 230: before use, the moving plate 233 is at the lowest point. At this time, the distance between the two moving plates 233 in the width direction of the threaded tube 600 is the farthest, so that the threaded tube 600 can smoothly enter between the two moving plates 233. Then, the lifting driver 231 will drive the lifting frame 235 and the pushing wheel 236 thereon to rise synchronously, and through the inclined surface of the moving plate 233, the moving plate 233 is gradually approached while rising, until the fixed wheel 232 on the moving plate 233 clamps and fixes the threaded tube 600 therein. During the rotation process, the fixed wheel 232 can assist the tube body of the threaded tube 600 to rotate, thereby reducing the friction between the threaded tube 600 and the moving plate 233, protecting the threaded tube 600 while also improving the rotation drive efficiency. When it is necessary to release the threaded tube 600, the lifting driver 231 stops working, and the two moving plates 233 can be restored to the initial position under the action of the buffer reset member 238, waiting for the next fixed support.

[0042] In this embodiment, the threaded tube 600 needs to be supported and fixed during the processing, and the threaded tube 600 needs to be in a rotating state. Therefore, in this embodiment, a chassis positioning component 210 and a tube body rotation driving component 220 are provided in the heating station, the grinding station and the deburring station. Figure 5 The tube body rotation drive assembly 220 and the chassis positioning assembly 210 in the heating station and the grinding station are shown. In this embodiment, the chassis positioning assembly 210 is arranged corresponding to the chassis 620 of the threaded tube 600 to be processed, and includes a plurality of positioning plates 211. The plurality of positioning plates 211 surround at least one limiting slot 212. The chassis 620 of the threaded tube 600 to be processed is embedded in at least one of the limiting slots 212. Based on this, the chassis 620 of the tube body can be embedded in the limiting slot 212 at a fixed angle, thereby achieving the fixing of the initial processing position of the threaded tube 600, thereby improving the processing accuracy and the stability of the processing quality. Furthermore, in this embodiment, corresponding to the heating station and the grinding station, there is a corresponding tube body rotation drive assembly 220 that can drive the chassis positioning assembly 210 to rotate synchronously. The tube body rotation drive assembly 220 includes a rotating motor 221. The chassis positioning assembly 210 is connected to the working end of the rotating motor 221 to provide a driving effect for the rotation of the threaded tube 600.

[0043] See also Figure 6 As shown, the heating mechanism 300 of this embodiment is provided with two heating components 310, which can achieve the purpose of removing impurities on the surface of the tube body and reducing the rigidity of the tube body after heating the threaded part, thereby facilitating the improvement of the quality of subsequent grinding processing. Specifically, any of the heating components 310 in this embodiment includes a heat source 311, at least one nozzle 312 and at least one heat pipe 313, the heat source 311 is preferably a flame spray gun, the nozzle 312 is connected to the heat source 311 through the corresponding heat pipe 313, and the nozzle 312 is arranged toward the waist hole 610 of the threaded tube 600 to be processed.

[0044] Furthermore, in order to improve the processing stability and ensure the heating effect in this embodiment, a temperature detection component 320 is also provided in the heating mechanism 300. The temperature detection component 320 is provided on one side of the heating component 310, and includes a temperature detector 321 and an adjustment frame 322. The working end of the temperature detector 321 is provided toward the waist hole 610 of the threaded pipe 600 to be processed, and moves around the threaded pipe 600 to be processed through the adjustment frame 322. Furthermore, the temperature detector 321 in this embodiment is preferably an infrared temperature measuring gun, and the operator can observe whether the heating component 310 effectively heats the waist hole 610 of the threaded pipe 600 through the temperature detector 321. Furthermore, the temperature detector 321 in this embodiment can adjust the detection position through the adjustment frame 322, so that it can be applied to pipes of different models or sizes.

[0045] It is worth noting that after heating, the impurities attached to the tube body and the doping elements inside the tube body will accumulate on its surface to form zinc slag and other impurities. If the above impurities fall into the tube body, it will not only affect the cleanliness of the fluid during subsequent use, but also increase the possibility of corrosion of the tube body, thereby greatly shortening the service life of the tube body. Therefore, in this embodiment, the zinc slag and other impurities generated after heating are purged and discharged through the slag discharge component 330 to ensure the cleanliness of the inside of the tube body. Specifically, the slag discharge component 330 in this embodiment also includes a mounting plate 333 and a docking pipe 332. The mounting plate 333 is arranged between the threaded tube 600 to be processed and the air supply part 331. One end of the docking pipe 332 is connected to the mounting plate 333, and the other end is arranged inside the tube body of the threaded tube 600 to be processed. The air supply pipe can move toward the docking pipe 332 to communicate with the docking pipe 332.

[0046] See also Figure 7 and Figure 8As shown, the grinding mechanism 400 in this embodiment grinds the surface of the threaded portion and the waist hole 610 through the grinding roller 410, and includes a roller driver 420 and a first slide 440, wherein the first slide 440 is slidably connected to the first adjustment module 430, and the roller driver 420 is arranged on the first slide 440, and the surface of the grinding roller 410 is covered with a brush and connected to the working end of the roller driver 420. Based on this, during the grinding process, the grinding roller 410 itself is in a high-speed rotation state and can achieve the purpose of moving along the first adjustment module 430, and at the same time, the threaded pipe 600 to be processed can rotate around its own axis, thereby greatly improving the efficiency and uniformity of the grinding process. Specifically, the roller driver 420 in this embodiment is preferably a rotary motor 221, and in different embodiments, it can also be set as other structures or devices that drive the grinding roller 410 to rotate, and the present invention does not make specific restrictions on this. In addition, the supporting rotating mechanism 200 in the grinding mechanism 400 is configured the same as the supporting rotating mechanism 200 in the heating station, and will not be described in detail here.

[0047] See also Fig. 9 As shown, in the deburring station, this embodiment provides another structural setting of the tube body rotation drive assembly 220, which is clamped on the tube body of the threaded tube 600, thereby being able to synchronously drive the tube body to rotate from the middle to both ends, and at the same time play a supporting effect on the tube body. Compared with the tube body rotation drive assembly 220 of the heating station or the grinding station, the tube body rotation drive assembly 220 of the deburring station has higher efficiency, faster response speed and can assist in supporting the tube body. The specific structure is as follows: The tube body rotation drive assembly 220 includes a rotating motor 221, a transmission belt 223 and a rotating motor 224. and a plurality of transmission wheels 222, the threaded tube 600 to be processed is clamped between the plurality of transmission wheels 222, at least one of the transmission wheels 222 is connected to the working end of the rotating motor 221, and the plurality of transmission wheels 222 are connected by the transmission belt 223. Based on the above structural arrangement, the transmission wheel 222 can not only provide a rotational driving effect for the threaded tube 600, but also limit the threaded tube 600 in the width direction thereof, and the synchronous rotation of the plurality of transmission wheels 222 can be achieved by only one rotating motor 221, thereby achieving a better driving effect.

[0048] See also Fig.10As shown, the deburring mechanism 500 includes a second adjusting module 510, a third adjusting module 520 and a lifting adjusting module 530 which are perpendicular to each other, wherein the second adjusting module 510 extends along the length direction of the threaded tube 600 to be processed, the third adjusting module 520 extends along the width direction of the threaded tube 600 to be processed, and the third adjusting module 520 extends along the height direction of the deburring mechanism 500. The third adjusting module 520 is slidably connected to the second adjusting module 510 through a second slide 550, and the lifting adjusting module 530 is slidably connected to the third adjusting module 520 through a third slide 560. The edge grinding component 540 moves along the lifting adjusting module 530 to be inserted into the waist hole 610 and move along the inner wall of the waist hole 610. Based on the above structural setting, the edge grinding component 540 can move in all directions and at multiple angles near the threaded tube 600, thereby greatly reducing the operating blind spots of the edge grinding component 540. Furthermore, the edge grinding assembly 540 in this embodiment includes a shell 541 and a grinding shaft 542, wherein the shell 541 is connected to the lifting and adjusting module 530, and the grinding shaft 542 extends toward the waist hole 610 of the threaded tube 600 to be processed. During processing, the grinding shaft 542 is correspondingly inserted into the waist hole 610.

Specifically, the burr detection component includes a plurality of infrared detectors 570, and the plurality of infrared detectors 570 are arranged toward the waist hole 610 of the threaded tube 600 to be processed to detect the burrs on the inner wall of the waist hole 610.

[0050] This embodiment also includes a control system, and the support rotation mechanism 200, the heating mechanism 300, the grinding mechanism 400, and the deburring mechanism 500 are respectively connected to the control system. In the actual production and processing process, the operator can control the above structures in real time through the control system, thereby improving the flexibility of the use of the device, and can also preset parameters through the control system, thereby improving the automation of the device.

[0055] Step S3, the threaded tube 600 to be processed is rotated around its axis again, and the waist hole 610 is polished at the same time; in this embodiment, the grinding roller 410 is moved along the outer wall of the threaded tube 600 to be processed and polished during the process of rotating the threaded tube 600 around its axis.

[0056] Step S4, deburring the inside of the waist hole 610, and then detecting burrs on the edge of the waist hole 610. When the detection is qualified, the material is left to stand; when the detection is unqualified, step S4 is repeated until the detection is qualified. In this embodiment, the edge grinding component 540 is inserted into the waist hole 610 and then grinds the inner wall of the waist hole 610. After completion, it is withdrawn from the waist hole 610. At this time, the burr detection component performs infrared detection on the inside of the waist hole 610 through the infrared detector 570 to determine the burr removal effect.

[0057] It is worth noting that in steps S1 to S4, the tube body of the threaded tube 600 to be processed is supported in the support assembly 230, and the fixed wheel 232 forms multiple rotation support points for the tube body, and the chassis 620 is placed in the chassis positioning assembly 210 to limit the placement angle of the threaded tube 600 to be processed; in steps S1 to S4, the threaded tube 600 to be processed is moved between the heating station, the grinding station and the deburring station by an external mobile device. Among them, the external mobile device includes but is not limited to a crane, a manipulator, a handling robot, etc.

[0058] The threaded pipe waist hole processing equipment and method described in the present invention fixes the threaded pipe 600 to be processed in the corresponding workstation through the supporting rotating mechanism 200, providing a stable working platform for the subsequent processing process, and at the same time heats the waist hole 610 of the threaded pipe 600 through the heating mechanism 300, thereby reducing the hardness of the corresponding part and removing impurities on the surface of the threaded pipe 600, and then blows out zinc slag and other impurities inside the pipe body through the slag removal component 330 to avoid the influence of impurities on the subsequent processing and use process, and then grinds the threaded part through the grinding mechanism 400 and removes the burrs on the edge of the waist hole 610 through the deburring mechanism 500, thereby realizing the fine processing process of the waist hole 610 of the threaded pipe 600. After the above processing, the problems such as poor assembly caused by the burrs at the waist hole 610 during conventional use, affecting the processing safety, interfering with the fluid and affecting the overall appearance can be avoided. Compared with the conventional technology at this stage, there are significant advantages in both assembly and use.
