The gear 211 is meshed with the No. 1 gear 29. Two No. 1 adjusting screw rods 23 are rotatably installed on the lower slide 21. The two No. 1 adjusting screw rods 23 are both threadedly connected to the upper slide 22. Twisting the two No. 1 adjusting screw rods 23 can adjust the upper slide 22 to slide forward or backward on the lower slide 21, so that the outer wall of the pipe can contact the abrasive belt 314, thereby meeting the processing of pipes of various diameters. A No. 2 adjusting screw rod 27 is rotatably installed on the upper slide 22. The No. 2 adjusting screw rod 27 is threadedly connected to the inner wall of the movable frame 26. The staff puts one end of the pipe against the clamping cone 25 on the No. 1 motor 24 and rotates the No. 2 adjusting screw rod 27. When the No. 2 adjusting screw rod 27 rotates, it drives the movable frame 26 to move to the left, and the movable frame 26 drives the clamping cone 25 above it to move to the left straight To the other end of the pipe, two clamping cones 25 are pressed against the two ends of the pipe to clamp and fix the pipe, and a reciprocating thread groove is provided on the reciprocating screw 210. The inner wall of the slide 21 is threadedly connected with the reciprocating thread groove of the reciprocating screw 210, and a ball is provided at the threaded connection. The No. 1 motor 24 drives the clamping cone 25 connected thereto to rotate, and the clamping cone 25 drives the pipe and the other clamping cone 25 to rotate. When the reciprocating screw 210 rotates, the cooperation of the reciprocating thread groove and the ball can drive the slide 21 to move back and forth left and right, and the slide 21 drives the upper slide 22 and the pipe above to move synchronously, so that the pipe can move back and forth left and right while rotating; a grinding device 3 is used for grinding the surface of the pipe, and the grinding device 3 is arranged on the clamping device 2 On one side, the grinding device 3 includes a mounting cover 31, which is mounted on the operating table 1. A movable block 35 is slidably mounted on the inner wall of the mounting cover 31. A limit block 36 is rotatably mounted on the movable block 35. A fourth gear 38 is connected to the limit block 36. A slider 33 is slidably mounted on the operating table 1. A connecting rod 34 is hinged on the slider 33. One end of the connecting rod 34 away from the slider 33 is hinged to the movable block 35. A protrusion 32 is connected to the outer wall of the downward sliding platform 21. The protrusion 32 contacts the slider 33 during movement. A return spring is arranged on the slider 33. A return spring is arranged on the movable block 35. When the slider 33 moves to the left, the movable block 35 is driven to move backward through the connecting rod 34. When the movable block 35 moves backward, the fourth gear 38 is driven to move backward through the limit block 36.The slider 33 and the movable block 35 can be reset forward by the elastic force of the reset spring. A tooth block 39 is slidably installed on the operating table 1 through the bracket. A slow-down damping is provided between the tooth block 39 and the bracket slidably connected thereto. The tooth block 39 falls slowly when not affected by external force. Teeth are provided on the tooth block 39. The fourth gear 38 meshes with the teeth on the tooth block 39 during the movement. When the fourth gear 38 moves backward, the teeth on the tooth block 39 can drive the fourth gear 38 to rotate ninety degrees. A slide groove 310 is provided on the tooth block 39. The slide groove 310 is a parallelogram arrangement. A lever 311 is installed on the movable block 35. The lever 311 is slidably connected to the slide groove 310. The sliding track of the lever 311 in the slide groove 310 is parallel The lever 311 first drives the tooth block 39 to move downwards and then drives the tooth block 39 to reset upwards, so that the fourth gear 38 can rotate ninety degrees when moving backwards, and the fourth gear 38 does not rotate when moving forwards. The inner wall of the mounting cover 31 is installed with a limit slot frame 37 through a bracket. The outer wall of the limit block 36 contacts the inner wall of the limit slot frame 37 during the movement. The limit block 36 is separated from the limit slot frame 37 during the movement backwards, and then the limit block 36 rotates ninety degrees with the fourth gear 38. After the limit block 36 resets forward, it enters the limit slot frame 37 again. The limit slot frame 37 fits with the three sides of the limit block 36, which enhances the stability of the limit block 36 and the fourth gear 38 during grinding. The fourth gear 38 is connected to a mounting plate 312, on which four wheel frames 313 are mounted, and on which sanding belts 314 are mounted via three pulleys. The four sanding belts 314 are set to four different meshes. The sanding belt 314 with the lowest mesh first contacts the surface of the pipe and grinds the surface of the pipe by rotating. When the fourth gear 38 moves, it drives the mounting plate 312 to move synchronously, so that the mounting plate 312 drives the four wheel frames 313 to rotate ninety degrees during the backward movement. After the four wheel frames 313 rotate ninety degrees, another sanding belt 314 is about to contact the pipe. A rotating shaft 315 is rotatably mounted on the mounting plate 312, on which a friction wheel 316 is fixedly connected. The four sanding belts 314 are The friction wheel 316 is in contact with the friction wheel 316. There is a large friction force between the surface of the friction wheel 316 and the sanding belt 314. When the friction wheel 316 rotates, it can drive the four sanding belts 314 to rotate. A sliding frame 317 is slidably installed on the side wall of the mounting cover 31. A long groove is opened on the side wall of the mounting cover 31. The sliding frame 317 is arranged on the long groove. The inner wall of the sliding frame 317 is rotatably connected with the outer wall of the rotating shaft 315. The sliding frame 317 can slide on the long groove of the mounting cover 31 with the rotating shaft 315. The sliding frame 317 plays the role of fixing the rotating shaft 315. The end of the rotating shaft 315 away from the mounting plate 312 is connected with the third gear 318. The third gear 318 is meshed with the first gear 29. When the first gear 29 rotates, it drives the rotating shaft 315 to rotate through the third gear 318.The rotating shaft 315 drives the friction wheel 316 to rotate, and the rotation direction of the sanding belt 314 is opposite to that of the pipe. The pipe completes one cycle of grinding operation after one reciprocating motion. After the second reciprocating motion of the pipe begins, the second sanding belt 314 performs the second cycle of grinding on the pipe. Similarly, the pipe undergoes four reciprocating motions, and the four sanding belts 314 grind the pipe in turn, completing a total of four cycles of grinding operations. The staff sets four sanding belts 314 with different mesh sizes in advance, and the four sanding belts 314 complete the grinding from coarse to fine in turn. The grinding device 3 also includes an inner slide 319, which is installed on the operating table 1. A slide bar 320 is slidably installed on the inner wall of the inner slide 319. A brush 321 is connected to the slide bar 320. The four sanding belts 314 contact the brush 321 in turn during the movement. An inclined wheel 323 is connected to the outer wall of the reciprocating screw 210. The inclined wheel 323 is inclined. A shift fork 322 is connected to the slide bar 320. The inclined wheel 323 is located in a shift fork groove set in the middle of the shift fork 322. When the inclined wheel 323 rotates, it can be moved by the shift fork. The fork 322 drives the slide bar 320 to slide left and right on the inner slide 319, and the slide bar 320 drives the brush 321 to move back and forth left and right. The brush 321 contacts the rotating sand belt 314 during the movement, and cleans the surface of the sand belt 314 to prevent metal particles and impurities from adhering to the surface of the sand belt 314 during the grinding process, thereby scratching the surface of the pipe during grinding. Through the cooperation of the grinding device 3 and the clamping device 2, the four sand belts 314 with different mesh sizes grind the pipe in turn during the four reciprocating movements of the pipe. The mesh of the sanding belt 314 is automatically changed from low to high, and the grinding accuracy is sequentially changed from coarse to fine, so as to achieve the required polishing effect. The staff has installed the corresponding sanding belt 314 in advance, and it does not need to be replaced again during the processing, which enhances the smoothness of the processing process and improves the work efficiency. Through the setting of the brush 321, the brush 321 cleans the surface of the sanding belt 314 when the sanding belt 314 is working, so as to avoid metal particles and impurities adhering to the surface of the sanding belt 314 and scratching the surface of the pipe during grinding, thereby affecting the appearance quality of the pipe.

[0023] For further information, see Fig.11The liquid spraying device 4 is used for spraying the grinding fluid. The liquid spraying device 4 is arranged on the grinding device 3. The liquid spraying device 4 includes a liquid tank 45. The liquid tank 45 is installed on the top of the mounting cover 31. The liquid tank 45 is filled with grinding fluid. An air pipe 44 and a liquid pipe 46 are installed on the liquid tank 45. The liquid pipe 46 is connected with an atomizing nozzle 47. A valve is arranged on the liquid pipe 46. The staff can close the liquid pipe 46 and adjust the amount of liquid spraying through the valve. An air bag 43 is installed on the outer wall of the liquid tank 45. The air bag 43 is in contact with the air pipe 44. A push rod 42 is slidably installed on the inner wall of the mounting cover 31. The top of the push rod 42 is connected to the bottom of the air bag 43. The outer wall of the rotating shaft 315 is connected with a cam 41. The cam 41 is in contact with the bottom of the push rod 42. The push rod 42 is provided with a complex The return spring on the push rod 42 keeps the push rod 42 in contact with the cam 41. When the cam 41 rotates, the push rod 42 is continuously pushed upward, so that the push rod 42 can reciprocate up and down. The air bag 43 can inject air into the liquid tank 45 through the air pipe 44. The liquid tank 45 uses the positive pressure principle to transport the grinding fluid inside it to the atomizing nozzle 47 through the liquid pipe 46. The atomizing nozzle 47 atomizes the grinding fluid and sprays it on the pipe being polished. Through the setting of the spraying device 4, during the polishing process of the pipe, the atomizing nozzle 47 can spray the grinding fluid on the position where the pipe is being polished to cool the pipe and prevent the pipe from overheating. At the same time, the polishing position is lubricated to promote the polishing effect and maintain the cleanliness of the pipe surface.

[0024] Further, see Fig.12 - Fig.14The recovery device 5 is used to recover the grinding fluid and metal waste. The recovery device 5 is arranged on the grinding device 3. The recovery device 5 is located at the lower side of the liquid spraying device 4. The recovery device 5 includes a recovery bucket 51. The recovery bucket 51 is installed on the mounting cover 31 through a bracket. The recovery bucket 51 is located at the bottom of the atomizing nozzle 47. A waste liquid box 53 and a waste residue box 54 are installed at the bottom of the recovery bucket 51. A filter screen 52 is installed on the inner wall of the recovery bucket 51. The waste liquid box 53 is located below the filter screen 52. After the grinding fluid mixed with the waste enters the recovery bucket 51, the filter screen 52 filters the grinding fluid. The waste is temporarily retained on the filter screen 52. The grinding fluid falls into the waste liquid box 53 through the filter screen 52. The waste liquid box 53 is connected with a recovery pipe 55, and a recovery box 56 is installed on the operating table 1. The end of the recovery pipe 55 away from the waste liquid box 53 is located above the recovery box 56. The grinding fluid in the waste liquid box 53 flows into the recovery box 56 through the recovery pipe 55 for collection. The staff can reuse the grinding fluid in the recovery box 56 to improve resource utilization. The recovery device 5 also includes a scraper 58, which is slidably installed on the inner wall of the recovery bucket 51. A pull rod 57 is installed on the scraper 58. The end of the pull rod 57 away from the scraper 58 is connected to the movable block 35. The scraper 58 contacts the filter screen 52 during the movement. The pull rod 57 pulls the scraper 58 backward, and the scraper 58 moves backward. When the filter 52 moves, the waste temporarily retained on the surface of the filter 52 is scraped backwards to maintain the cleanliness of the filter 52 and avoid clogging of the filter 52; the recovery device 5 also includes a flip cover 59, which is rotatably installed on the inner wall of the recovery bucket 51, and the flip cover 59 is located above the waste slag box 54. The flip cover 59 is connected to an inclined rod 510, and a resistance rod 511 is installed at the bottom of the pull rod 57. The resistance rod 511 contacts the inclined rod 510 during the movement. When the pull rod 57 moves backward, the resistance rod 511 on the pull rod 57 contacts the inclined rod 510 and pushes the inclined rod 510 backward, so that when the inclined rod 510 moves backward, the flip cover 59 is driven to flip upward, and the scraper strip 58 scrapes the waste into the waste slag box 54 , the waste residue is collected, and after the scraper bar 58 is reset, the flip cover 59 falls and resets by its own gravity, so that more grinding fluid is prevented from entering the waste residue box 54 and affecting the volume of the waste residue box 54; through the setting of the recovery device 5, the used grinding fluid is filtered by the filter screen 52 and recovered into the recovery box 56, which is convenient for the staff to reuse it, achieving the effect of saving resources and improving resource utilization; through the setting of the scraper bar 58, the waste generated in the processing of the pipe can be scraped into the waste residue box 54 by the scraper bar 58 for collection, achieving the effect of solid-liquid separation and collection, which is convenient for the staff to recycle the metal waste and avoid the clogging of the filter screen 52.

[0025] With the above structure, the working principle of this case is that the staff puts one end of the pipe against the clamping cone 25 on the No. 1 motor 24, and the other end of the pipe is aligned with the other clamping cone 25, and the No. 2 adjusting screw 27 is turned. When the No. 2 adjusting screw 27 is rotated, it drives the movable frame 26 to move to the left, and the movable frame 26 drives the clamping cone 25 above it to move to the left until it presses against the other end of the pipe. The two clamping cones 25 press against the two ends of the pipe to clamp and fix the pipe. Similarly to the No. 2 adjusting screw 27, twisting the two No. 1 adjusting screws 23 can adjust the upper slide 22 to slide forward or backward on the lower slide 21, so that the outer wall of the pipe can contact the sanding belt 314, thereby meeting the processing of pipes of various diameters, and starting the No. 1 motor 24 and the No. 2 motor 28, the No. 1 motor 24 The clamping cone 25 connected thereto is driven to rotate, and the clamping cone 25 drives the pipe and another clamping cone 25 to rotate. The No. 2 motor 28 drives the No. 2 gear 211 to rotate through the No. 1 gear 29. The No. 2 gear 211 drives the reciprocating screw 210 to rotate. When the reciprocating screw 210 rotates, the cooperation of the reciprocating thread groove and the ball bearing can drive the lower slide 21 to move back and forth left and right. The lower slide 21 drives the upper slide 22 and the pipe above to move synchronously, so that the pipe can move back and forth left and right while rotating. The No. 1 gear 29 drives the rotating shaft 315 to rotate through the No. 3 gear 318 while rotating. The rotating shaft 315 drives the friction wheel 316 to rotate. The sanding belt 314 can rotate on the wheel frame 313 through three pulleys. Since the friction wheel 316 and the four sanding belts are connected to each other, the friction wheel 316 and the four sanding belts are connected to each other. The belt 314 is in contact with the pipe, and there is a large friction force between the surface of the friction wheel 316 and the sanding belt 314, so that when the friction wheel 316 rotates, it can drive the four sanding belts 314 to rotate. The four sanding belts 314 are set to four different meshes. The sanding belt 314 with the lowest mesh first contacts the surface of the pipe and grinds the surface of the pipe by rotating. The pipe moves to the right first and then to the left. The sanding belt 314 grinds from the right end to the left end of the pipe in sequence, and then grinds from the left end to the right end of the pipe. The rotation direction of the sanding belt 314 is opposite to the rotation direction of the pipe. The pipe completes a cycle of grinding operation after one reciprocating movement; when the slide table 21 moves, it drives the protrusion 32 to move synchronously. When the protrusion 32 moves to the left and contacts the slider 33, the pipe is a cycle at this time. After the grinding is completed, the slide 21 continues to move to the left, so that the protrusion 32 drives the slider 33 to move to the left. Due to the limiting effect of the mounting cover 31 on the movable block 35, the movable block 35 can only slide back and forth on the mounting cover 31. When the slider 33 moves to the left, the movable block 35 is driven to move backward through the connecting rod 34. When the movable block 35 moves backward, it drives the fourth gear 38 to move backward through the limiting block 36. During the backward movement, the fourth gear 38 contacts the teeth on the tooth block 39 and rotates. When the fourth gear 38 rotates ninety degrees, the fourth gear 38 does not contact the teeth. The teeth on the tooth block 39 can drive the fourth gear 38 to rotate ninety degrees. After the fourth gear 38 rotates ninety degrees, the slide 21 turns to move to the right, and the protrusion 32 moves to the right accordingly.The slider 33 and the movable block 35 are reset by the elastic force of the reset spring. During the process of the movable block 35 resetting forward, the limit block 36 drives the fourth gear 38 to move forward and reset. When the movable block 35 moves, the movable block 35 drives the lever 311 to move synchronously. When the lever 311 moves backward, it slides along the slide groove 310. The sliding track of the lever 311 in the slide groove 310 is a parallelogram. When the fourth gear 38 rotates ninety degrees, the lever 311 moves to the rear side along the bottom side of the parallelogram track in the slide groove 310. In this process, the lever 311 presses the tooth block 39 downward for a distance. After that, the lever 311 enters the upper side of the parallelogram track and moves forward. At the same time, the fourth gear 38 rotates ninety degrees. The gear 38 is reset forward, and since the tooth block 39 moves downward, the fourth gear 38 does not contact the teeth when it resets forward, and the fourth gear 38 does not rotate. When the fourth gear 38 is about to reset, the lever 311 enters the front side of the parallelogram track and pushes the tooth block 39 upward to reset the tooth block 39. In the process of sliding one circle in the slide groove 310, the lever 311 first drives the tooth block 39 downward, and then drives the tooth block 39 to reset upward, thereby achieving the effect that the fourth gear 38 can rotate ninety degrees when moving backward, and the fourth gear 38 does not rotate when moving forward. The limit block 36 disengages from the limit slot frame 37 during the process of moving backward, and then the limit block 36 rotates ninety degrees with the fourth gear 38. After 36 is reset forward, it enters the limit slot frame 37 again. The limit slot frame 37 is fitted with the three sides of the limit block 36, which enhances the stability of the limit block 36 and the fourth gear 38 during grinding, and prevents shaking and affecting the grinding operation. A slow-down damping is provided between the tooth block 39 and the bracket slidably connected thereto. When the tooth block 39 is not affected by external forces, it falls slowly. When the fourth gear 38 moves, it drives the mounting plate 312 to move synchronously, so that the mounting plate 312 drives the four wheel frames 313 to rotate ninety degrees during the backward movement. After the four wheel frames 313 rotate ninety degrees, another sanding belt 314 is about to contact the pipe. When the mounting plate 312 moves backward, it drives the third gear 318 to move backward through the rotating shaft 315. After the No. 3 gear 318 moves backward, it disengages from the No. 1 gear 29, causing the friction wheel 316 to stop rotating. After the mounting plate 312 is reset forward, the No. 3 gear 318 meshes with the No. 1 gear 29 again, causing the friction wheel 316 to drive the four sanding belts 314 to rotate again. During this process, the sliding frame 317 follows the rotating shaft 315 to slide on the long groove of the mounting cover 31. The sliding frame 317 plays the role of fixing the rotating shaft 315. After the second reciprocating motion of the pipe begins, the second sanding belt 314 performs the second cycle of grinding on the pipe. Similarly, the pipe undergoes four reciprocating motions, and the four sanding belts 314 grind the pipe in turn, completing a total of four cycles of grinding operations. The staff sets four sanding belts 314 with different mesh sizes in advance.The four abrasive belts 314 complete the grinding operation from rough to fine in sequence; when the reciprocating screw rod 210 rotates, the inclined wheel 323 is driven to rotate. Since the inclined wheel 323 is inclined, the inclined wheel 323 can drive the slide bar 320 to slide left and right on the inner slide 319 through the fork 322 when the inclined wheel 323 rotates, and the slide bar 320 drives the brush 321 to move back and forth left and right. The brush 321 contacts the rotating abrasive belt 314 during the movement to clean the surface of the abrasive belt 314, so as to prevent the abrasive belt 314 from adhering to the surface of the metal particles and impurities during the grinding process, and scratching the surface of the pipe during grinding; through the cooperation of the grinding device 3 and the clamping device 2, the pipe During the four reciprocating motions, four sanding belts 314 with different mesh sizes grind the pipe in turn. The mesh size of the sanding belt 314 is automatically changed from low to high, and the grinding accuracy is performed from coarse to fine in turn, so as to achieve the required polishing effect. The staff installs the corresponding sanding belt 314 in advance, and it does not need to be replaced again during the processing, which enhances the smoothness of the processing process and improves the work efficiency. Through the setting of the brush 321, the brush 321 cleans the surface of the sanding belt 314 when the sanding belt 314 is working, so as to avoid metal particles and impurities adhering to the surface of the sanding belt 314 and scratching the surface of the pipe during grinding, thereby affecting the appearance quality of the pipe.

[0026] The liquid tank 45 is filled with grinding fluid. When the rotating shaft 315 rotates, the cam 41 is driven to rotate. The return spring on the push rod 42 keeps the push rod 42 in contact with the cam 41. When the cam 41 rotates, the push rod 42 is constantly pushed upward, so that the push rod 42 can reciprocate up and down. When the push rod 42 reciprocates up and down, it constantly squeezes the air bag 43, so that the air bag 43 continuously injects air into the liquid tank 45 through the air pipe 44. The liquid tank 45 uses the positive pressure principle to transport the grinding fluid inside it to the atomizing nozzle 47 through the liquid pipe 46. The atomizing nozzle 47 sprays the grinding fluid on the pipe being ground. A valve is provided on 46, and the staff can close the liquid pipe 46 and adjust the spraying amount through the valve. The grinding fluid sprayed on the pipe can have a certain cooling effect to prevent the pipe from overheating, and also have a certain lubricating effect, making the grinding effect more delicate, and can also wash away the waste generated by grinding the surface of the pipe; through the setting of the liquid spraying device 4, during the grinding process of the pipe, the atomizing nozzle 47 can spray the grinding fluid on the position where the pipe is being ground, cool the pipe, prevent the pipe from overheating, and lubricate the grinding position at the same time, promote the grinding effect, and maintain the cleanliness of the pipe surface.

[0027] The grinding fluid sprayed from the atomizing nozzle 47 drips into the recovery bucket 51 after contacting the pipe. After the grinding fluid mixed with the waste material enters the recovery bucket 51, the filter 52 filters the grinding fluid, and the waste material is temporarily retained on the filter 52. The grinding fluid passes through the filter 52 and falls into the waste liquid box 53. The grinding fluid in the waste liquid box 53 flows into the recovery box 56 through the recovery pipe 55 for collection. The staff can reuse the grinding fluid in the recovery box 56, thereby improving resource utilization. When the movable block 35 moves backward, the movable block 35 pulls the scraper bar 58 backward through the pull rod 57. When the scraper bar 58 moves backward, the waste temporarily retained on the surface of the filter screen 52 is scraped backward to maintain the cleanliness of the filter screen 52 and avoid clogging of the filter screen 52. When the movable block 35 moves forward, the scraper bar 58 is reset through the pull rod 57. When the pull rod 57 moves backward, the resistance rod 511 on the pull rod 57 contacts the inclined rod 510 and pushes the inclined rod 510 backward. The scraper 58 is moved so that the inclined rod 510 moves backward and drives the flip cover 59 to flip upward. After the flip cover 59 flips upward, the scraper bar 58 scrapes the waste into the waste slag box 54 to collect the waste slag. After the scraper bar 58 is reset, the flip cover 59 falls and resets by its own gravity. The flip cover 59 is only opened when the scraper bar 58 is working and closed when the scraper bar 58 is not working, so as to prevent more grinding fluid from entering the waste slag box 54 and affecting the volume of the waste slag box 54; through the setting of the recovery device 5, the used grinding fluid is filtered by the filter screen 52 and recovered into the recovery box 56, which is convenient for the staff to reuse it, achieving the effect of saving resources and improving resource utilization; through the setting of the scraper bar 58, the waste generated in the processing of the pipe can be scraped into the waste slag box 54 by the scraper bar 58 for collection, achieving the effect of solid-liquid separation and collection, which is convenient for the staff to recycle the metal waste and avoid the clogging of the filter screen 52.
