A buffer pad is fixedly connected to the upper end of the base, and a sponge layer is attached to the surface of the buffer pad. The sponge layer can effectively reduce scratches on the bottom end of the stainless steel pipe. The buffer pad can provide cushioning and reduce damage caused by the falling of the stainless steel pipe. A scale is engraved on the outer end of the vertical rod, and the scale corresponds to the horizontal direction of the connecting frame. The scale can facilitate technicians to adjust the horizontal position of the connecting frame, making it convenient for technicians to fine-grind the inner wall of the stainless steel pipe. A bearing is fixedly connected to the inner wall of the stabilizing ring, and the bearing and the connecting rod have an interference fit. The stabilizing ring and the bearing can effectively support the connecting rod, and at the same time limit the connecting rod to reduce the possibility of vertical displacement of the connecting rod.

A clamping block 12 is bolted to the bottom of the adjusting rod 11. The inner side of the clamping block 12 is clamped to the outer side of the connecting pipe 7.

[0040] Specifically, such as Figure 4 As shown, a groove 14 is provided on the front side of the top of the processing table 1, a collecting plate 15 is bolted to the top side of the groove 14, a guide plate 16 is bolted to the bottom side of the groove 14, a drain pipe 17 is connected to the bottom side of the groove 14, and an electromagnetic valve 18 is provided on the outside of the drain pipe 17.

[0041] In this embodiment, by arranging the bellows 6, the connecting pipe 7, the auxiliary block 8, the concave block 9, the limit spring 10, the adjusting rod 11, the clamping block 12 and the nozzle 13, when the grinding is completed and the debris and waste lubricating fluid need to be cleaned, the bellows 6 is started, and then an air flow is generated in the bellows 6, and the air flow is transmitted through the connecting pipe 7 connected at the top, and then the air flow is blown out through the nozzle 13 connected at the bottom of the connecting pipe 7. The air flow blown out by the nozzle 13 acts on the grinding area, and blows the debris and waste lubricating fluid generated by the grinding away from the interior of the stainless steel pipe. At the same time, the limit spring 10 and the adjusting rod 11 are used to adjust the position of the connecting pipe 7 to ensure that the connecting pipe 7 stably blows air to the grinding area. After the grinding is completed, the connecting pipe 7 is clamped and placed by using the adjusting rod 11 and the block 503. By setting the groove 14, the collection plate 15, the guide plate 16, the drain pipe 17 and the electromagnetic valve 18, when the bellows 6 is started, the debris and waste lubricating fluid generated by the grinding are blown to the top of the collection plate 15 through the connecting pipe 7 and the nozzle 13. Then the collection plate 15 will preliminarily filter and collect larger particles of impurities. Then, the liquid containing the waste lubricating fluid will flow to the drain pipe 17 through the guide plate 16 bolted on the bottom side under the action of gravity. When the collected liquid and debris need to be discharged, the electromagnetic valve 18 is opened and the waste lubricating fluid will be discharged for subsequent recycling.

[0042] Specifically, such as Figure 7 As shown, a protective shell 19 is bolted to the top of the support platform 405 , and a laser rangefinder body 20 is bolted to the interior of the protective shell 19 .

By providing a fixed block 21, a placement groove 22, and a support rod 23, during the movement of the connecting block 404, the support rod 23 plays a role in guiding and stabilizing the connecting block 404, thereby ensuring the smooth movement of the connecting block 404 on the threaded rod 403.

[0045] Specifically, such as Figure 5 As shown, a placement block 24 is bolted to the rear side of the support frame 501 , and a rubber block 25 is bolted inside the placement block 24 .

By providing an anti-slip pad 26, the friction between the ground and the workbench is increased to prevent the device from sliding due to vibration or external force during operation, thereby ensuring the stability and safety of the device.

[0048] Working principle: When using the stainless steel pipe inner wall grinding device, first, place the stainless steel pipe on the front side of the top of the workbench, then start the positioning motor 506, and then the output end of the positioning motor 506 drives the double-axis screw 507 to rotate. Since the outer side of the double-axis screw 507 is connected to the movable plate 508 by a thread, and the right side of the double-axis screw 507 is rotatably connected to the inner side of the right limit plate 505, when the double-axis screw 507 rotates, the movable plate 508 will move on the screw, and then the splint 509 fixed on the inner side of the movable plate 508 will move close to the stainless steel pipe as the movable plate 508 moves, thereby realizing the clamping operation of the stainless steel pipe, and then start the motor body 402, and then the output end of the motor body 402 drives the threaded rod 403 Rotation, since the outer side of the threaded rod 403 is connected to the connecting block 404 through a thread, and the front side of the threaded rod 403 is rotatably connected to the inner side of the placement plate 401, the connecting block 404 will move on the threaded rod 403, and then the support platform 405 fixedly connected to the inner side of the connecting block 404 will move with the connecting block 404, and the bottom of the support platform 405 is slidably connected to the inner side of the slide groove 2, which ensures the stability of the movement of the support platform 405. When the support platform 405 moves to the appropriate position, the drive motor 407 is started, and then the output end of the drive motor 407 drives the grinding wheel 408 to rotate, and starts to grind the inner wall of the stainless steel pipe. During the grinding process, the water pump 410 bolted to the front side of the storage box 409 on the left side of the top of the support platform 405 can be started as needed. , the water pump 410 delivers the lubricating oil in the storage tank 409 to the rear side of the grinding wheel 408 through the delivery pipe 411 to lubricate the grinding wheel 408 and the inner wall of the stainless steel pipe. When the grinding is completed and the debris and waste lubricating liquid need to be cleaned, the bellows 6 is started, and then an air flow is generated in the bellows 6. The air flow is transmitted through the connecting pipe 7 connected at the top, and the air flow is then blown out through the nozzle 13 connected at the bottom of the connecting pipe 7. The air flow blown out by the nozzle 13 acts on the grinding area, and the debris and waste lubricating liquid generated by the grinding are blown away from the inside of the stainless steel pipe. At the same time, the limit spring 10 and the adjusting rod 11 are used to adjust the position of the connecting pipe 7 to ensure that the connecting pipe 7 stably blows air to the grinding area. Then, after the grinding is completed, the adjusting rod 11 and the block 503 are used to adjust the position of the connecting pipe 7 to ensure that the connecting pipe 7 stably blows air to the grinding area. The connecting pipe 7 is clamped and placed, and then the connecting pipe 7 and the nozzle 13 blow the debris and waste lubricating liquid generated by grinding to the top of the collecting plate 15, and then the collecting plate 15 will preliminarily filter and collect the larger particles of impurities, and then the liquid containing the waste lubricating liquid will flow to the drain pipe 17 through the guide plate 16 bolted on the bottom side under the action of gravity. When the collected liquid and debris need to be discharged, the electromagnetic valve 18 is opened, and the waste lubricating liquid will be discharged for subsequent recycling. In this way, the existing stainless steel pipe inner wall grinding device is not convenient for stably clamping the stainless steel pipe, which causes the steel pipe to shake or shift during the grinding process, affecting the grinding accuracy and quality, and it is not convenient to add lubricating oil during the grinding process of longer stainless steel pipes.The friction coefficient between the polishing head and the inner wall of the stainless steel pipe is increased, the inner wall of the stainless steel pipe is locally overheated and deformed, and the size precision and surface smoothness of subsequent processing are affected.

[0049] The above are only preferred embodiments of the present application, and are not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
