Description

Technical Field

[0001] The utility model relates to the technical field of crystallizer copper tube polishing, in particular to a flexible polishing device for crystallizer copper tubes. Background Art

[0002] A crystallizer is a common device in industrial fields such as metallurgy and chemical industry, which is used to cool and crystallize the dissolved substances in liquid alloys or solutions to achieve purposes such as purification and separation. The crystallizer copper tube refers to a group of copper tubes used for heat transfer of fluids in the crystallizer. After the crystallizer copper tube is cut, the cutting surfaces at both ends need to be polished.

[0003] The existing flexible polishing device for crystallizer copper tubes (publication number: CN217224859U) has at least the following drawbacks: the above device fixes the copper tube vertically on the convex platform, uses the expansion plate and the clamping plate to fix the copper tube, and then grinds the end face through the grinding disc that moves up and down. However, the grinding disc located above the copper tube can only polish one end of the copper tube at a time. When polishing the other end, the copper tube needs to be flipped and refixed, and the operation is cumbersome, resulting in low polishing efficiency of the copper tube. Therefore, we propose the present utility model. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the drawbacks existing in the prior art, and to propose a flexible polishing device for crystallizer copper tubes.

[0005] In order to achieve the above purpose, the present utility model adopts the following technical scheme:

[0006] A flexible polishing device for crystallizer copper tubes includes a mounting seat. The mounting seat is U-shaped. A polishing structure is arranged inside the mounting seat. The polishing structure includes a rotating rod rotatably arranged inside the mounting seat. Two grinding discs are spline-connected to the outer circumferential wall of the rotating rod. The two grinding discs are fixed to the rotating rod by bolts. A copper tube body is arranged between the two grinding discs. The two ends of the copper tube body are respectively attached to the mutually close sides of the grinding discs. The first motor drives the rotating rod to rotate, so that the grinding discs can polish the two ends of the copper tube body.

[0007] As a further scheme of the present utility model, a first motor is fixed to one side of the mounting seat. The output end of the first motor penetrates one side of the mounting seat and is fixed to one end of the rotating rod. Two support plates are arranged on the top surface of the mounting seat. Two fixing rods are rotatably arranged between the two support plates. Tension plates are fixed to the mutually far sides of the two fixing rods. The two fixing rods are slidably inserted into the inside of the copper tube body. The tension plates are in contact with the inner circumferential wall of the copper tube body. The tension plates can fix the copper tube body from the inside.

[0008] As a further solution of the present utility model, movable disks are rotatably arranged on one side of each of the two support plates close to each other. Installation grooves are formed on one side of each of the two movable disks. A bidirectional screw rod is rotatably arranged inside the installation grooves. The positive and negative threads of the bidirectional screw rod are respectively threadedly connected with two movable blocks. The corresponding ends of the two movable blocks on the right side are fixed to the corresponding ends of the two fixed rods. The corresponding ends of the two movable blocks on the left side are slidably inserted into the corresponding ends of the two fixed rods. A second motor is fixed to one side of the support plate on the right side. The output end of the second motor penetrates through one side of the support plate and is fixed to one side of the movable disk.

[0009] As a further solution of the present utility model, a chute is formed on the top surface of the mounting seat. A sliding strip is slidably arranged inside the chute. The sliding strip is fixed to the bottom surface of the support plate on the left side. The cross sections of the sliding strip and the chute are both T-shaped.

[0010] As a further solution of the present utility model, the side of the tensioning plate close to the inside of the copper tube body is an arc surface. An anti-slip pad is fixed to the arc surface side of the tensioning plate.

[0011] As a further solution of the present utility model, two limiting shafts are slidably inserted into the top surface of the mounting seat. One side of each of the two limiting shafts abuts against one side of the support plate on the left side.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] For this polishing device, through the setting of the polishing structure, rotate the bidirectional screw rod, use the two movable blocks to drive the two fixed rods to approach or move away from each other, so that the tensioning plate can tension and fix copper tube bodies of different thicknesses. The staff slides the two grinding disks according to the length of the copper tube body so that they abut against both ends of the copper tube body, and then fixes the positions of the grinding disks through bolts;

[0014] The first motor drives the rotating rod to rotate clockwise, so that the grinding disks polish both ends of the copper tube body. The second motor drives the movable disk to rotate counterclockwise, and the fixed rod drives the copper tube body to rotate through the tensioning plate, so that the grinding disks can fully polish both ends of the copper tube body. In this way, it is realized that both ends of the copper tube body can be polished simultaneously in one time, improving the polishing efficiency of the copper tube body and ensuring the polishing effect of the copper tube body.

[0023] Such as Figures 1-4As shown in the figure, a flexible polishing device for a crystallizer copper tube includes a mounting base 1. The mounting base 1 is U-shaped. A polishing structure is provided inside the mounting base 1. The polishing structure includes a rotating rod 2 rotatably arranged inside the mounting base 1. Two grinding discs 201 are splined to the outer circumferential wall surface of the rotating rod 2. The two grinding discs 201 are fixed to the rotating rod 2 by bolts. A copper tube body 203 is arranged between the two grinding discs 201. The two ends of the copper tube body 203 are respectively in contact with the closer sides of the grinding discs 201. The first motor drives the rotating rod 2 to rotate, enabling the grinding discs 201 to polish the two ends of the copper tube body 203.

[0024] In this embodiment, a first motor is fixed to one side of the mounting base 1. The output end of the first motor penetrates one side of the mounting base 1 and is fixed to one end of the rotating rod 2. Two support plates 204 are arranged on the top surface of the mounting base 1. Two fixing rods 205 are rotatably arranged between the two support plates 204. Tension plates 202 are fixed to the mutually remote sides of the two fixing rods 205. The two fixing rods 205 are slidably inserted into the interior of the copper tube body 203. The tension plates 202 are in contact with the inner circumferential wall surface of the copper tube body 203, and the tension plates 202 can fix the copper tube body 203 from the inside.

[0025] In this embodiment, movable disks 3 are rotatably arranged on the sides of the two support plates 204 close to each other. Installation grooves 301 are formed on one side of each of the two movable disks 3. A bidirectional screw 302 is rotatably arranged inside the installation groove 301. Two movable blocks 303 are respectively threadedly connected to the positive and negative threads of the bidirectional screw 302. The corresponding ends of the two movable blocks 303 on the right side are fixed to the corresponding ends of the two fixed rods 205. The corresponding ends of the two movable blocks 303 on the left side are slidably inserted into the corresponding ends of the two fixed rods 205. A second motor is fixed to one side of the right support plate 204. The output end of the second motor penetrates through one side of the support plate 204 and is fixed to one side of the movable disk 3. Through the setting of the polishing structure, the staff inserts the fixed rod 205 into the inside of the copper tube body 203, rotates the bidirectional screw 302, and uses the two movable blocks 303 to drive the two fixed rods 205 to approach or move away from each other, so that the tensioning plate 202 can tension and fix copper tube bodies 203 of different thicknesses. Then, the staff slides the two grinding disks 201 according to the length of the copper tube body 203, so that the two grinding disks 201 are respectively abutted against the two ends of the copper tube body 203, and then fixes the positions of the grinding disks 201 through bolts. The first motor and the second motor are started. The first motor drives the rotating rod 2 to rotate clockwise, so that the grinding disks 201 follow the rotation of the rotating rod 2 to polish the two ends of the copper tube body 203. The second motor drives the movable disk 3 to rotate counterclockwise. The movable disk 3 drives the two fixed rods 205 to rotate. The fixed rods 205 drive the copper tube body 203 to rotate through the tensioning plate 202, so that the grinding disks 201 can fully polish the two ends of the copper tube body 203. In this way, the two ends of the copper tube body 203 can be polished simultaneously in one time, the polishing efficiency of the copper tube body 203 is improved, and the polishing effect of the copper tube body 203 is ensured.

[0026] In this embodiment, a chute 4 is formed on the top surface of the mounting base 1. A sliding strip 401 is slidably arranged inside the chute 4. The sliding strip 401 is fixed to the bottom surface of the left support plate 204. The cross sections of the sliding strip 401 and the chute 4 are both T-shaped. When the staff takes and places the copper tube body 203 on the fixed rod 205, the left support plate 204 can be slid to the left, so that the insertion between the movable block 303 on one side of the left support plate 204 and one end of the fixed rod 205 is cancelled, so as to facilitate the staff to take and place the copper tube body 203 on the fixed rod 205.

[0027] In this embodiment, the side of the tensioning plate 202 close to the inside of the copper tube body 203 is an arc surface. An anti-slip pad is fixed to the arc surface side of the tensioning plate 202. The anti-slip pad is made of rubber material. When the tensioning plate 202 is tensioned inside the copper tube body 203, the anti-slip pad can increase the friction between the tensioning plate 202 and the inner wall of the copper tube body 203, and improve the fixing effect.

[0028] In this embodiment, two limiting shafts 5 are slidably inserted into the top surface of the mounting base 1. One side of each of the two limiting shafts 5 abuts against one side of the left support plate 204. After the left support plate 204 is reset and the left movable block 303 is reconnected to one end of the fixing rod 205, the staff can insert the limiting shaft 5 to fix the position of the left support plate 204 and prevent the position of the left support plate 204 from shifting.

[0029] Working principle: During use, the staff inserts the fixing rod 205 into the inside of the copper tube body 203, rotates the bidirectional screw rod 302, and uses the two movable blocks 303 to drive the two fixing rods 205 to approach or move away from each other, so that the tensioning plate 202 can tension and fix copper tube bodies 203 of different thicknesses. Then, the staff slides the two grinding discs 201 according to the length of the copper tube body 203, so that the two grinding discs 201 respectively abut against both ends of the copper tube body 203, and then fixes the positions of the grinding discs 201 through bolts. The first motor and the second motor are started. The first motor drives the rotating rod 2 to rotate clockwise, so that the grinding discs 201 follow the rotation of the rotating rod 2 to polish both ends of the copper tube body 203. The second motor drives the movable disc 3 to rotate counterclockwise, the movable disc 3 drives the two fixing rods 205 to rotate, and the fixing rods 205 drive the copper tube body 203 to rotate through the tensioning plate 202, so that the grinding discs 201 can fully polish both ends of the copper tube body 203. When the staff takes and places the copper tube body 203 on the fixing rod 205, the left support plate 204 can be slid to the left, so that the movable block 303 on one side of the left support plate 204 is disengaged from the insertion with one end of the fixing rod 205, so as to facilitate the staff to take and place the copper tube body 203 on the fixing rod 205. When the tensioning plate 202 is tensioned inside the copper tube body 203, its anti-slip pad can increase the friction between the tensioning plate 202 and the inner wall of the copper tube body 203 and improve the fixing effect. After the left support plate 204 is reset and the left movable block 303 is reconnected to one end of the fixing rod 205, the staff can insert the limiting shaft 5 to fix the position of the left support plate 204 and prevent the position of the left support plate 204 from shifting.
