Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, and in particular to a pipe end grinding device for pipe installation. Background Technology

[0002] During installation, pipelines are usually connected in series. Due to errors during pipeline production, and the accumulation of errors among multiple pipelines, the final length of the two pipelines to be connected may exceed the standard. In order to ensure successful pipeline connection, the pipelines need to be cut and polished to meet the set length. Polishing also ensures that the pipe ends of the connected pipelines remain smooth, resulting in good sealing after connection.

[0003] In existing grinding devices, the grinding part is usually fixed to one side of the pipe. The pipe to be ground is set perpendicular to the grinding part so that the grinding part can grind the end of the pipe flat and smooth. However, during pipe installation, it is sometimes necessary to bend and connect the pipes. The cut pipe ends are end faces, and existing grinding devices are not convenient for grinding inclined end faces. Summary of the Invention

[0030] Please refer to Figure 1-11 A pipe end grinding device includes a base plate 1, a slide rail 11 disposed at the top of the base plate 1, a slide plate 12 slidably connected to the slide rail 11, a clamping mechanism 2 disposed on the slide plate 12, a drive assembly 3 disposed on the base plate 1, an adjustment mechanism 4 disposed at the top of the base plate 1, a grinding assembly 5 disposed on the adjustment mechanism 4, and a cooling mechanism 6 disposed on the base plate 1. The pipe 7 to be ground is placed in the clamping mechanism 2, which fixes the pipe 7. The adjustment mechanism 4 adjusts the tilt angle between the grinding assembly 5 and the pipe 7. The grinding assembly 5 grinds the end of the pipe 7. The cooling mechanism 6 cools the grinding assembly 5 to prevent it from overheating due to prolonged grinding.

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

[0032] The base 21 has a notch 211 at its upper end and a notch 241 at its lower end. The notch 211 is V-shaped and the notch 241 is an inverted V-shape. The pipe 7 is placed between the notch 211 and the notch 241. The top of the base 21 has a groove 212. The pressure block 24 matches the groove 212 and can slide up and down within the groove 212. The pressure block 24 has a groove 242 on one side and matches the limiting post 22.

[0033] Two limiting posts 22 are provided, two grooves 242 are provided, and the pressure block 24 is slidably disposed between the two limiting posts 22. The arrangement of the two limiting posts 22 and the grooves 242 maintains the stable up-and-down sliding of the pressure block 24.

[0034] In use, the pipe 7 is placed between the first notch 211 and the second notch 241. The rotating rod 261 is rotated, which drives the rotating block 26 and the lead screw 25 to rotate. Under the limitation of the fixed plate 23 and the limiting post 22, the lead screw 25 rotates and drives the pressure block 24 to move vertically up and down. The pressure block 24 and the base 21 cooperate to fix pipes 7 of various diameters.

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

[0036] Before polishing, the cylinder 31 drives the slide plate 12 to move the clamping mechanism 2 and the pipe 7 closer to the polishing assembly 5, so that the end of the pipe 7 contacts the polishing assembly 5. The cylinder 31 continues to push forward, and the circular block 32 begins to compress the spring 34. The compressed spring 34 applies a force to the base plate 12 towards the polishing assembly 5, causing the clamping mechanism 2 and the pipe 7 to apply pressure towards the polishing assembly 5, so that the end of the pipe 7 abuts against the polishing assembly 5. During polishing, the polishing assembly 5 polishes the end of the pipe 7. The compressed spring 34 applies elastic force to the base 21, keeping the end of the pipe 7 abutting against the polishing assembly 5. This allows for more polishing of the end of the pipe 7 at once, reducing the number of times the distance between the pipe 7 and the polishing assembly 5 needs to be adjusted after polishing.

[0037] The adjustment mechanism 4 includes a rotating seat 41 rotatably mounted on the top of the base plate 1, a gear 42 rotatably mounted on the top of the rotating seat 41, a gear 43 rotatably mounted on the top of the base plate 1, a housing 44 mounted on the top of the base plate 1, and a motor 45 mounted on the top of the housing 44. The gear 43 is located at the output end of the motor 45. The gear 42 and the gear 43 mesh with each other. A rotating platform 421 is mounted on the top of the gear 42.

[0038] The motor 45 drives the gear 43 to rotate, the gear 43 rotates and drives the gear 42 to rotate, and the gear 42 rotates and drives the rotating table 421 to rotate.

[0039] The rotating base 41, the first gear 42 and the second gear 43 are all disposed inside the outer casing 44. The rotating platform 421 is rotatably connected to the top of the outer casing 44 and is disposed through the outer casing 44.

[0040] The grinding assembly 5 includes a second motor 51 mounted on the top of the rotary table 421, a grinding disc 52 mounted on the output end of the second motor 51, and a support plate 53 mounted on the top of the base plate 1. The support plate 53 is an arc-shaped plate, concentrically arranged with the rotary table 421, and has a horizontally arranged sliding groove 531. 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 and grind the end of the pipe 7.

[0041] The rotating table 421 rotates, driving the second motor 51 and the grinding disc 52 to rotate. The output end of the second motor 51 rotates in the slide groove 531, causing the angle between the grinding disc 52 and the pipe 7 to change, so that the grinding disc 52 can grind the inclined end face of the pipe 7.

[0042] The cooling mechanism 6 includes a liquid storage tank 61 disposed at the top of the base plate 1, a delivery pipe 62 disposed on one side of the liquid storage tank 61, a pump 63 connected to the delivery pipe 62, a mounting plate 64 disposed at the top of the support plate 53, a limiting plate 641 disposed on one side of the mounting plate 64, a pressure plate 642 slidably disposed on one side of the mounting plate 64, a second spring 65 surrounding the outer circumference of the delivery pipe 62, and a driving member 240 disposed on one side of the pressure block 24. A fixing strip 643 is disposed on one side of the mounting plate 64. The delivery pipe 62 is disposed through the fixing strip 643, the pressure plate 642, and the limiting plate 641 in sequence. The delivery pipe 62 is fixedly connected to both the fixing strip 643 and the pressure block 24. The section of the delivery pipe 62 between the fixing strip 643 and the pressure plate 642 is a corrugated pipe. The second spring 65 is disposed between the pressure plate 642 and the limiting plate 641.

[0043] A vertical slide groove is provided on one side of the mounting plate 64. The pressure plate 642 is slidably connected to the vertical slide groove. When the driving member 240 presses down on the pressure plate 642, the pressure plate 642 will drive the lower end of the conveying pipe 62 to move downward, while compressing the second spring 65, and the bellows is stretched. When the driving member 240 lifts up and no longer presses down on the pressure plate 642, the compressed second spring 65 will push 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 provided at the top of the liquid storage tank 61. A support plate 611 is provided on one side of the liquid storage tank 61. The delivery pipe 62 passes through the upper part of the support plate 611 and is slidably connected to the limiting plate 641.

[0045] During polishing, the pump 63 pumps the coolant in the storage tank 61 to the top of the pipe 7 to rinse and cool the polished end of the pipe 7. The used coolant and the polished debris fall back into the storage tank 61 through the filter holes under the action of gravity, reducing coolant loss. The small debris mixed with coolant can be reused to increase the friction of the polished end, which has a polishing effect.

[0046] The driving component 240 is Z-shaped. Its lower end is fixedly connected to the pressure block 24, and its upper end is located above the pressure block 24. The side of the upper end of the driving component 240 closest to the grinding disc 52 is an inclined surface 240a. In use, the position of the driving component 240 varies depending on the diameter of the pipe 7. When the pipe 7 has a large diameter, the driving component 240 is higher than the pressure plate 642, and the position of the conveying pipe 62 remains unchanged. When the pipe 7 has a small diameter, the upper end of the driving component 240 presses down on the pressure plate 642, causing the outlet end of the conveying pipe 62 to move downwards, closer to the end of the pipe 7, allowing for closer cooling of the grinding end of the pipe 7.
