Description

Technical Field

[0001] This utility model belongs to the field of crystallizer copper tube processing technology, and particularly relates to an internal cavity polishing device for crystallizer copper tube processing. Background Technology

[0002] A crystallizer copper tube is an accessory used in continuous casting machines for steel casting. It is formed by directly pouring molten steel into the crystallizer copper tube. During the manufacturing process of the crystallizer copper tube, the inner wall of the crystallizer copper tube may be uneven and have low smoothness. Therefore, the inner wall of the crystallizer copper tube needs to be polished during the processing of the crystallizer copper tube, which requires the use of polishing equipment.

[0003] Crystallizer copper tubes come in various sizes. Current internal polishing equipment lacks the function of changing the size of the polishing mechanism. Therefore, when dealing with crystallizer copper tubes of different sizes, it is necessary to change the corresponding polishing head, which is cumbersome and increases the cost of use. To address this, an internal polishing device for processing crystallizer copper tubes is provided. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that current polishing equipment does not have a polishing mechanism for changing dimensions, and to propose an internal polishing device for processing copper tubes in crystallizers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an internal cavity polishing device for processing copper tubes in a crystallizer, comprising a base, the upper surface of which is provided with a groove and a sliding groove, a protective cover fixedly installed on the outer surface of the base, a drive motor fixedly installed on the inner wall of the protective cover, a threaded column fixedly installed at the output end of the drive motor, one end of the threaded column being rotatably connected to the inner side wall of the sliding groove, a movable sleeve threadedly installed on the outer surface of the threaded column, a support block fixedly installed on the upper surface of the movable sleeve, an installation cover fixedly installed on the upper surface of the support block, a servo motor fixedly installed on the inner wall of the installation cover, a rotating cylinder fixedly installed at the output end of the servo motor, a polishing component provided at one end of the rotating cylinder, and a positioning component provided on the inner wall of the groove;

[0006] The polishing assembly includes a fixed cylinder and a sliding sleeve. The side wall of the fixed cylinder is fixedly connected to the side wall of the rotating cylinder. A stroke groove is provided on the outer surface of the fixed cylinder. A spring rod is fixedly installed on the outer surface of the fixed cylinder. A grinding plate is fixedly installed at one end of the spring rod. Sandpaper is fixedly installed on the outer surface of the grinding plate.

[0007] A tapered column is fixedly installed on the inner wall of the fixed cylinder, a sliding ring is slidably installed on the inner surface of the fixed cylinder, and a connecting spring is fixedly installed on the inner surface of the sliding ring.

[0008] A mounting ring is fixedly installed at one end of the connecting spring, and a push rod is fixedly installed on the inner wall of the mounting ring. One end of the push rod extends to the lower surface of the mounting ring, and one end of the push rod is in contact with the outer surface of the tapered column.

[0009] The other end of the push rod passes through the interior of the connecting spring and extends to the outside of the fixed cylinder through the stroke groove. The outer surface of the grinding plate is provided with a sliding groove, and one end of the push rod is slidably connected to the inner wall of the sliding groove.

[0010] As a further description of the above technical solution:

[0011] A connecting rod is fixedly installed on the side wall of the sliding ring. One end of the connecting rod extends into the interior of the rotating cylinder. The outer surface of the rotating cylinder is provided with a moving groove and a positioning hole. One end of the connecting rod extends to the outside of the rotating cylinder through the moving groove. The inner surface of the sliding sleeve is slidably connected to the outer surface of the rotating cylinder. The inner surface of the sliding sleeve is fixedly connected to one end of the connecting rod.

[0012] As a further description of the above technical solution:

[0013] A positioning spring is fixedly installed on the upper surface of the sliding sleeve. A positioning plate is fixedly installed on one end of the positioning spring. A positioning pin is fixedly installed on the lower surface of the positioning plate. One end of the positioning pin passes through the interior of the positioning spring and extends to the outside of the inner surface of the sliding sleeve. One end of the positioning pin is adapted to the positioning hole.

[0014] As a further description of the above technical solution:

[0015] The positioning assembly includes a bidirectional threaded rod, one end of which is rotatably connected to the inner sidewall of the groove, and the other end of which is fixedly mounted with a drive bolt. One end of the drive bolt extends to the outside of the sidewall of the base, and a fixing nut is threaded onto the outer surface of the drive bolt.

[0016] As a further description of the above technical solution:

[0017] The outer surface of the bidirectional threaded rod is threaded with two threaded sleeves. The outer surface of the threaded sleeves is slidably connected to the inner wall of the groove. A support plate is fixedly installed on the upper surface of the threaded sleeves. A positioning plate is fixedly installed on the side wall of the support plate. A friction pad is fixedly installed on the side wall of the positioning plate.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, by setting a polishing component, one end of the positioning pin is disengaged from the positioning hole, and then the sliding sleeve moves on the outer surface of the rotating cylinder. At this time, the sliding sleeve drives the sliding ring to move inside the fixed cylinder through the connecting rod. As the sliding ring moves, it drives the push rod to move on the outer surface of the conical column. When the push rod moves towards the positioning plate on the conical column, one end of the push rod moves towards the outside of the fixed cylinder through the stroke groove, thereby expanding the grinding plate outward under the support of the spring rod, thus increasing the grinding diameter of the grinding plate. When the push rod moves in the opposite direction, the grinding plate retracts towards the fixed cylinder, thus reducing the grinding diameter of the grinding plate. This realizes the function of the polishing mechanism on the polishing equipment to change according to the inner diameter of the crystallizer copper tube, so that the polishing equipment can meet the polishing treatment of crystallizer copper tubes of different sizes, improving the polishing range of the polishing equipment and improving the practicality of the polishing equipment.

[0020] 2. In this utility model, by setting a positioning component, the crystallizer copper tube is placed between two positioning plates. After loosening the fixing nut, the bidirectional threaded rod is driven by the drive bolt to rotate in the groove. Under the action of the thread, the threaded sleeve will move towards the center of the groove. At this time, the threaded sleeve will drive the support plate to move synchronously, thereby driving the positioning plate to clamp and fix the crystallizer copper tube through the friction pad. The structure is simple and facilitates the quick installation and disassembly of the crystallizer copper tube by the polishing equipment, improving the working efficiency of the polishing equipment. At the same time, the friction pad increases the friction between the positioning plate and the crystallizer copper tube, thereby improving the stability of clamping and fixing the crystallizer copper tube.

[0029] The polishing assembly 5 includes a fixed cylinder 51 and a sliding sleeve 513. The side wall of the fixed cylinder 51 is fixedly connected to the side wall of the rotating cylinder 4. The outer surface of the fixed cylinder 51 is provided with a stroke groove 52. A spring rod 56 is fixedly installed on the outer surface of the fixed cylinder 51. A grinding plate 53 is fixedly installed at one end of the spring rod 56. Sandpaper 58 is fixedly installed on the outer surface of the grinding plate 53. A tapered column 55 is fixedly installed on the inner side wall of the fixed cylinder 51. A sliding ring 54 is slidably installed on the inner surface of the fixed cylinder 51. A connecting spring 59 is fixedly installed on the inner surface of the sliding ring 54. An installation ring 510 is fixedly installed at one end of the connecting spring 59. A push rod 511 is fixedly installed on the inner wall of the installation ring 510. One end of the push rod 511 extends to the lower surface of the installation ring 510. One end of the push rod 511 is in contact with the outer surface of the tapered column 55. The other end of the push rod 511... A connecting rod 511 extends through the interior of the connecting spring 59 and through the stroke groove 52 to the exterior of the fixed cylinder 51. The outer surface of the grinding plate 53 is provided with a sliding groove 57. One end of the push rod 511 is slidably connected to the inner wall of the sliding groove 57. A connecting rod 512 is fixedly installed on the side wall of the sliding ring 54. One end of the connecting rod 512 extends into the interior of the rotating cylinder 4. The outer surface of the rotating cylinder 4 is provided with a moving groove 6 and a positioning hole 7. One end of the connecting rod 512 extends into the exterior of the rotating cylinder 4 through the moving groove 6. A positioning spring 514 is fixedly installed on the upper surface of the sliding sleeve 513. A positioning plate 515 is fixedly installed on one end of the positioning spring 514. A positioning pin 516 is fixedly installed on the lower surface of the positioning plate 515. One end of the positioning pin 516 passes through the interior of the positioning spring 514 and extends to the exterior of the inner surface of the sliding sleeve 513. One end of the positioning pin 516 is adapted to the positioning hole 7.

[0030] The specific implementation method is as follows: According to the inner diameter of the copper tube of the crystallizer, one end of the positioning pin 516 is disengaged from the positioning hole 7, and then the sliding sleeve 513 is moved on the outer surface of the rotating cylinder 4. At this time, the sliding sleeve 513 drives the sliding ring 54 to move inside the fixed cylinder 51 through the connecting rod 512. As the sliding ring 54 drives the push rod 511 to move on the outer surface of the conical column 55, when the push rod 511 moves towards the positioning plate 94 on the conical column 55, one end of the push rod 511 will move towards the outside of the fixed cylinder 51 through the stroke groove 52, thereby expanding the grinding plate 53 towards the outside of the fixed cylinder 51 under the support of the spring rod 56, thereby increasing the grinding diameter of the grinding plate 53. When the push rod 511 moves in the opposite direction, the grinding plate 53 will retract towards the fixed cylinder 51, thereby reducing the grinding diameter. The grinding diameter of the grinding plate 53 is adjusted to match the inner diameter of the crystallizer copper tube. The positioning pin 516 is inserted into the positioning hole 7 under the action of the positioning plate 515 and the positioning spring 514. The grinding plate 53 is fixed by fixing the sliding sleeve 513. Then, the servo motor in the mounting cover 3 drives the rotating cylinder 4 to rotate. The rotating cylinder 4 drives the fixed cylinder 51 to rotate synchronously. The fixed cylinder 51 drives the grinding plate 53 to rotate through the spring rod 56. The grinding plate 53 polishes the inner surface of the crystallizer copper tube with sandpaper 58. During the polishing process, the drive motor in the protective cover 10 drives the threaded column 12 to rotate. Under the action of the thread, the moving sleeve drives the support block 2 to move, thereby driving the polishing assembly 5 to move on the crystallizer copper tube through the drive motor.

[0031] The positioning component 9 includes a bidirectional threaded rod 91. One end of the bidirectional threaded rod 91 is rotatably connected to the inner wall of the groove 8. The other end of the bidirectional threaded rod 91 is fixedly mounted with a drive bolt 96. One end of the drive bolt 96 extends to the outside of the side wall of the base 1. A fixing nut 97 is threadedly mounted on the outer surface of the drive bolt 96. Two threaded sleeves 92 are threadedly mounted on the outer surface of the bidirectional threaded rod 91. The outer surface of the threaded sleeves 92 is slidably connected to the inner wall of the groove 8. A support plate 93 is fixedly mounted on the upper surface of the threaded sleeves 92. A positioning plate 94 is fixedly mounted on the side wall of the support plate 93. A friction pad 95 is fixedly mounted on the side wall of the positioning plate 94. The inner surface of the sliding sleeve 513 is slidably connected to the outer surface of the rotating cylinder 4. The inner surface of the sliding sleeve 513 is fixedly connected to one end of the connecting rod 512.

[0032] The specific implementation method is as follows: place the crystallizer copper tube between the two positioning plates 94, then loosen the fixing nut 97, and drive the bidirectional threaded rod 91 to rotate in the groove 8 through the drive bolt 96. Under the action of the thread, the threaded sleeve 92 will move towards the center of the groove 8. At this time, the threaded sleeve 92 will drive the support plate 93 to move synchronously, thereby driving the positioning plate 94 to clamp and fix the crystallizer copper tube through the friction pad 95.

[0033] Working principle: The crystallizer copper tube is placed between two positioning plates 94. After loosening the fixing nut 97, the double-threaded rod 91 is rotated in the groove 8 by the drive bolt 96. Under the action of the thread, the threaded sleeve 92 moves towards the center of the groove 8. At this time, the threaded sleeve 92 drives the support plate 93 to move synchronously, thereby driving the positioning plate 94 to clamp and fix the crystallizer copper tube through the friction pad 95. Then, according to the inner diameter of the crystallizer copper tube, one end of the positioning pin 516 is disengaged from the positioning hole 7, and the sliding sleeve 513 moves on the outer surface of the rotating cylinder 4. At this time, the sliding sleeve 513 drives the sliding ring 54 to move inside the fixed cylinder 51 through the connecting rod 512. As the sliding ring 54 moves, it drives the top rod 511 to move on the outer surface of the conical column 55. When the top rod 511 moves towards the positioning plate 94 on the conical column 55, one end of the top rod 511 moves outward through the stroke groove 52, thereby placing the grinding plate 53 on the spring rod 5. Supported by 6, it expands outward towards the fixed cylinder 51, thereby increasing the grinding diameter of the grinding plate 53. When the push rod 511 moves in the opposite direction, the grinding plate 53 will retract towards the fixed cylinder 51, thus reducing the grinding diameter of the grinding plate 53. When the grinding diameter of the grinding plate 53 is adjusted to be suitable for the inner diameter of the crystallizer copper tube, the positioning pin 516 is inserted into the positioning hole 7 under the action of the positioning plate 515 and the positioning spring 514. The grinding plate 53 is fixed by fixing the sliding sleeve 513. Then, the servo motor in the mounting cover 3 drives the rotating cylinder 4 to rotate. The rotating cylinder 4 drives the fixed cylinder 51 to rotate synchronously. The fixed cylinder 51 drives the grinding plate 53 to rotate through the spring rod 56. The grinding plate 53 polishes the inner surface of the crystallizer copper tube through the sandpaper 58. During the polishing process, the drive motor in the protective cover 10 drives the threaded column 12 to rotate. Under the action of the thread, the moving sleeve drives the support block 2 to move, thereby driving the polishing component 5 to move in the crystallizer copper tube through the drive motor.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
