A pipe 7 to be polished is placed in the clamping mechanism 2, the clamping mechanism 2 fixes the pipe 7, the adjusting mechanism 4 adjusts the inclination angle between the grinding component 5 and the pipe 7, the grinding component 5 grinds the end of the pipe 7, and the cooling mechanism 6 cools the grinding component 5 to prevent the grinding component 5 from overheating due to long-term polishing.

[0031] Specifically, the clamping mechanism 2 includes a base 21 arranged on the slide 12, a limiting column 22 arranged on the base 21, a fixed plate 23 arranged on the limiting column 22, a pressure block 24 slidably arranged on one side of the limiting column 22, a screw rod 25 rotatably arranged at the top of the pressure block 24, and a rotating block 26 arranged at the top of the screw rod 25, the pressure block 24 is slidably connected to the base 21, the screw rod 25 is threadedly connected to the fixed plate 23, and a rotating rod 261 is arranged on the rotating block 26.

[0032] A notch 211 is provided at the upper end of the base 21, and a notch 241 is provided at the lower end of the pressing block 24. The notch 211 is V-shaped, and the notch 241 is inverted V-shaped. The pipe 7 is placed between the notch 211 and the notch 241. A groove 212 is provided at the top of the base 21, and the pressing block 24 matches the groove 212. The pressing block 24 can slide up and down in the groove 212. A groove 242 is provided on one side of the pressing block 24, and the groove 242 matches the limiting column 22.

[0033] There are two limit posts 22 , two second grooves 242 , and the pressing block 24 is slidably arranged between the two limit posts 22 . The arrangement of the two limit posts 22 and the second grooves 242 keeps the pressing block 24 sliding stably up and down.

[0034] When in use, the pipe 7 is placed between the notch 1 211 and the notch 241, and the rotating rod 261 is rotated to drive the rotating block 26 and the screw rod 25 to rotate. Under the limitation of the fixed plate 23 and the limiting column 22, the screw rod 25 rotates to drive the pressing block 24 to move vertically up and down. The pressing block 24 and the base 21 can cooperate to fix pipes 7 of various diameters.

[0035] The driving assembly 3 includes a cylinder 31 arranged on the base plate 1, a round block 32 arranged at the output end of the cylinder 31, a telescopic rod 33 arranged on one side of the round block 32, and a spring 34 sleeved outside the telescopic rod 33, one end of the round block 32 is connected to the slide plate 12, one end of the spring 34 is connected to the round block 32, and the other end of the spring 34 is connected to the slide plate 12.

[0036] Before grinding, the cylinder 31 drives the slide plate 12 to drive the clamping mechanism 2 and the pipe 7 to move toward the grinding assembly 5, so that the end of the pipe 7 contacts the grinding assembly 5. The cylinder 31 continues to push forward, and the round block 32 begins to compress the spring 1 34. The compressed spring 1 34 applies a force toward the grinding assembly 5 to the bottom plate 12, driving the clamping mechanism 2 and the pipe 7 to apply pressure toward the grinding assembly 5, so that the end of the pipe 7 abuts against the grinding assembly 5. During grinding, the grinding assembly 5 grinds the end of the pipe 7, and the compressed spring 1 34 applies elastic force to the base 21, so that the end of the pipe 7 and the grinding assembly 5 remain in a state of abutment, so that more end of the pipe 7 can be ground at one time, reducing the number of times the distance between the pipe 7 and the grinding assembly 5 needs to be adjusted after grinding.

[0037] The adjusting mechanism 4 includes a rotating seat 41 rotatably arranged at the top of the base plate 1, a gear 1 42 arranged at the top of the rotating seat 41, a gear 2 43 rotatably arranged at the top of the base plate 1, a shell 44 arranged at the top of the base plate 1 and a motor 1 45 arranged at the top of the shell 44, the gear 2 43 is arranged at the output end of the motor 1 45, the gear 1 42 and the gear 2 43 are meshed with each other, and a rotating table 421 is arranged at the top of the gear 1 42.

[0038] The motor 1 45 drives the gear 2 43 to rotate. The rotation of the gear 2 43 drives the gear 1 42 to rotate. The rotation of the gear 1 42 drives the rotating platform 421 to rotate.

[0039] The rotating seat 41 , the gear 1 42 and the gear 2 43 are all disposed in the housing 44 . The rotating platform 421 is rotatably connected to the top end of the housing 44 , and the rotating platform 421 is disposed through the housing 44 .

[0040] The grinding assembly 5 includes a second motor 51 disposed at the top of the rotating table 421, a grinding disc 52 disposed at the output end of the second motor 51, and a support plate 53 disposed at the top of the bottom plate 1, wherein the support plate 53 is an arc-shaped plate, and the support plate 53 is concentrically disposed with the rotating table 421, and a slide groove 531 is disposed on the support plate 53, and the slide groove 531 is horizontally disposed, and the output end of the second motor 51 is slidably connected to the support plate 53. The second motor 51 drives the grinding disc 52 to rotate to grind the end of the pipe 7.

[0041] The rotation of the rotating table 421 drives the motor 2 51 and the grinding disc 52 to rotate, and the output end of the motor 2 51 rotates in the slide groove 531, so that the angle formed between the grinding disc 52 and the pipe 7 changes, so that the grinding disc 52 can grind the inclined end surface of the end of the pipe 7.

[0042] The cooling mechanism 6 includes a liquid storage tank 61 arranged at the top of the base plate 1, a delivery pipe 62 arranged at one side of the liquid storage tank 61, a pump 63 connected to the delivery pipe 62, a mounting plate 64 arranged at the top of the support plate 53, a limiting plate 641 arranged at one side of the mounting plate 64, a pressing plate 642 slidably arranged at one side of the mounting plate 64, a spring 2 65 arranged around the outer circumference of the delivery pipe 62 and a driving member 240 arranged at one side of the pressing block 24, a fixing bar 643 is arranged at one side of the mounting plate 64, the delivery pipe 62 passes through the fixing bar 643, the pressing plate 642 and the limiting plate 641 in sequence, the delivery pipe 62 is fixedly connected to the fixing bar 643 and the pressing block 24, a section of the delivery pipe 62 located between the fixing bar 643 and the pressing plate 642 is a bellows, and the spring 2 65 is arranged between the pressing plate 642 and the limiting plate 641.

[0043] A vertical slide groove is set on one side of the mounting plate 64, and the pressure plate 642 is slidably connected to the vertical slide groove. The driving member 240 presses down the pressure plate 642, and the pressure plate 642 drives the lower end of the conveying pipe 62 to move downward, while compressing the spring 2 65, and the bellows is stretched; when the driving member 240 is lifted up and no longer presses down the pressure plate 642, the compressed spring 2 65 pushes the pressure plate 642 upward due to the elastic force.

[0044] The liquid storage tank 61 is located below the grinding disc 52 , a filter hole is arranged at the top of the liquid storage tank 61 , a support plate 611 is arranged at one side of the liquid storage tank 61 , and the delivery pipe 62 passes through the upper part of the support plate 611 and is slidably connected with the limit plate 641 .

[0045] During grinding, the pump 63 pumps the coolant in the liquid storage tank 61 to the top of the end of the pipe 7 to flush and cool the grinded end of the pipe 7. The used coolant and the grinded debris fall back into the liquid storage tank 61 through the filter holes under the action of gravity, reducing the loss of coolant. The small debris mixed with the coolant can be used again to increase the friction of the grinded end, thereby achieving a polishing effect.

[0046] The driving member 240 is Z-shaped, the lower end of the driving member 240 is fixedly connected to the pressing block 24, the upper end of the driving member 240 is located above the pressing block 24, and the upper end of the driving member 240 close to the grinding disc 52 is an inclined surface 240a. When in use, the position of the driving member 240 varies with the diameter of the pipe 7. When the diameter of the pipe 7 is large, the position of the driving member 240 is higher than the pressing plate 642, and the position of the delivery pipe 62 does not change; when the diameter of the pipe 7 is small, the upper end of the driving member 240 will press down the pressing plate 642, driving the outlet end of the delivery pipe 62 to move downward, close to the end of the pipe 7, and can cool the grinding end of the pipe 7 more closely.
