[0001] This utility model relates to the field of graphite tube processing technology, specifically to a polishing device for the inner cavity of an antioxidant graphite tube mold. Background Technology

[0002] Antioxidant graphite tubes are typically used in high-temperature and corrosive environments (such as semiconductor, photovoltaic, and metallurgical industries), where the core requirements are to extend service life and maintain structural stability at high temperatures.

[0003] Most existing anti-oxidation graphite tube mold inner cavity polishing devices cannot achieve rapid replacement of polishing rollers, which is inconvenient when they need to be disassembled and reassembled after long-term use. They also cannot meet the polishing needs of graphite tubes of different specifications or inner diameters. Therefore, we propose an anti-oxidation graphite tube mold inner cavity polishing device to solve the problems mentioned in the background technology. Utility Model Content

[0004] The purpose of this invention is to provide an anti-oxidation graphite tube mold inner cavity polishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-oxidation graphite tube mold inner cavity polishing device, comprising a base, a frame, a drive motor, a drive shaft, a locking assembly, and a polishing assembly. The frame is fixedly connected to the top of the base by bolts, the drive motor is fixedly mounted on the upper surface of the frame, the drive shaft is fixedly connected to the output shaft of the drive motor, the locking assembly is fixedly connected to the bottom end of the drive shaft, and the polishing assembly is snapped onto the locking assembly.

[0006] Furthermore, the locking assembly includes a connecting sleeve, which is fixedly connected to the bottom end of the drive shaft. A guide rod is symmetrically mounted on the top of the connecting sleeve, and a sliding sleeve is slidably connected to the guide rod along the axial direction. A movable ring is fixedly connected between the two sliding sleeves. A Y-shaped locking bracket is symmetrically mounted on the bottom of the movable ring, and a sliding bracket is symmetrically mounted on the outer side of the movable ring. A threaded sleeve is fixedly mounted on the outer side of the sliding bracket, and a locking screw is internally threaded onto the threaded sleeve. A locking hole adapted to the locking screw is opened on the outer side of the connecting sleeve.

[0007] Furthermore, the top of the connecting sleeve is symmetrically provided with through-holes, the top of the guide rod is fixedly connected with a baffle, and a push spring is sleeved on the surface of the guide rod and below the sliding sleeve.

[0008] Furthermore, the polishing assembly includes a mounting base, a connecting rod, and a polishing roller body. The two ends of the connecting rod are fixedly connected to the mounting base and the polishing roller body, respectively. The mounting base is inserted into the inside of the connecting sleeve. A rectangular seat is symmetrically mounted on the top of the mounting base. A fixed shaft is mounted on the top of the rectangular seat. A rotating locking block adapted to the insertion port is rotatably connected to the fixed shaft.

[0009] Furthermore, the rotating block is symmetrically provided with insertion holes adapted to the Y-shaped locking frame, and the two insertion parts of the Y-shaped locking frame pass through the two insertion holes respectively.

[0010] Furthermore, a limiting slide plate is symmetrically installed on the outer side of the mounting base, and a limiting groove adapted to the limiting slide plate is provided on the inner wall of the connecting sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the polishing roller body needs to be removed and replaced, the locking screw is first rotated to disengage its end from the connecting sleeve. The return spring will push the sliding sleeve and moving ring vertically upward under the limit of the guide rod, thereby driving the Y-shaped locking frame to move upward and disengage it from the rotating block. At this time, the rotating block can be rotated under the connection of the fixed shaft until it coincides with the insertion port. The mounting seat can then be pulled down from the connecting sleeve to remove the polishing roller body. Similarly, during installation, the above steps are reversed. This anti-oxidation graphite tube mold inner cavity polishing device has a reasonable structural design and is easy to use. It uses a snap-fit ​​method to fix the polishing roller. When it is damaged after long-term use and needs to be replaced, it can be quickly removed and replaced without the aid of tools. The quick-release design can also install polishing rollers of different diameters, thus adapting to the use of anti-oxidation graphite tubes with different inner diameters, making it highly applicable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 An anti-oxidation graphite tube mold inner cavity polishing device includes a base 1, a frame 2, a drive motor 3, a drive shaft 4, a locking component 5, and a polishing component 6. The frame 2 is fixedly connected to the top of the base 1 by bolts. The drive motor 3 is fixedly installed on the upper surface of the frame 2. The drive shaft 4 is fixedly connected to the output shaft of the drive motor 3. The locking component 5 is fixedly connected to the bottom end of the drive shaft 4. The polishing component 6 is snapped onto the locking component 5.

[0022] The locking assembly 5 includes a connecting sleeve 51, which is fixedly connected to the bottom end of the drive shaft 4. A guide rod 52 is symmetrically mounted on the top of the connecting sleeve 51. A sliding sleeve 53 is slidably connected to the guide rod 52 along the axial direction. A moving ring 54 is fixedly connected between the two sliding sleeves 53. A Y-shaped locking bracket 55 is symmetrically mounted on the bottom of the moving ring 54. A sliding bracket 56 is symmetrically mounted on the outer side of the moving ring 54. A screw sleeve 57 is fixedly mounted on the outer side of the sliding bracket 56. A locking screw 58 is internally threaded onto the screw sleeve 57. A locking hole adapted to the locking screw 58 is opened on the outer side of the connecting sleeve 51. The sliding bracket 56 can be fixed by using the locking screw 58, thereby forming the fixation of the Y-shaped locking bracket 55.

[0023] The top of the connecting sleeve 51 is symmetrically provided with through-holes 59. The top of the guide rod 52 is fixedly connected with a baffle. A push spring 510 is sleeved on the surface of the guide rod 52 and below the sliding sleeve 53. After the locking screw 58 is unscrewed, the push spring 510 can push the sliding sleeve 53, the moving ring 54 and the Y-shaped locking bracket 55 to move upward, so that the Y-shaped locking bracket 55 is disengaged from the rotating block 66, thus facilitating its rotation.

[0024] The polishing assembly 6 includes a mounting base 61, a connecting rod 62, and a polishing roller body 63. The two ends of the connecting rod 62 are fixedly connected to the mounting base 61 and the polishing roller body 63, respectively. The mounting base 61 is inserted into the inside of the connecting sleeve 51. A rectangular seat 64 is symmetrically mounted on the top of the mounting base 61. A fixed shaft 65 is mounted on the top of the rectangular seat 64. A rotating locking block 66 adapted to the insertion port 59 is rotatably connected to the fixed shaft 65. When it is necessary to install or remove the mounting base 61, the rotating locking block 66 should be rotated to the state of being aligned with the insertion port 59 under the connection of the fixed shaft 65, so as to facilitate pushing in or pulling out. After installation, the rotating locking block 66 should be rotated half a turn, and then the lower contact surface of the rotating locking block 66 should be engaged with the upper contact surface of the connecting sleeve 51 to fix the mounting base 61. The Y-type locking bracket 55 is used to further fix the rotating locking block 66. When the rotating shaft 4 is rotated, the rotating locking block 66 can rotate freely due to centrifugal force.

[0025] The rotating block 66 has symmetrically arranged insertion holes 67 that are adapted to the Y-type locking bracket 55, and the two insertion parts of the Y-type locking bracket 55 pass through the two insertion holes 67 respectively.

[0026] The mounting base 61 is symmetrically equipped with a limiting slide plate 68 on its outer side. The inner wall of the connecting sleeve 51 is provided with a limiting groove 511 that is adapted to the limiting slide plate 68. The limiting slide plate 68 and the limiting groove 511 can not only allow the rotating locking block 66 used for snap-fit ​​connection to pass through the insertion port 59, but also prevent the mounting base 61 from shaking due to the large centrifugal force of the connecting sleeve 51 when it is rotating.

[0027] A worktable 8 is fixedly connected to the top of the base 1 via a lifting cylinder 7. Vertical plates 9 are symmetrically installed on the top of the worktable 8. Electric push rods 10 are fixedly installed on opposite sides of the two vertical plates 9. A clamping seat 11 is installed on the telescopic end of the electric push rod 10. The anti-oxidation graphite tube to be polished in the inner cavity of the mold is placed on the top of the worktable 8. The electric push rod 10 drives the clamping seat 11 to move, thereby clamping and fixing it, and facing the bottom of the polishing roller body 63. When working, the drive motor 3 is turned on, and the drive shaft 4 can drive the locking component 5 and the polishing component 6 to rotate synchronously, thereby realizing the rotation of the polishing roller body 63. The lifting cylinder 7 drives the worktable 8 to move upward, thereby realizing the polishing work of the inner cavity of the anti-oxidation graphite tube.

[0028] This anti-oxidation graphite tube mold inner cavity polishing device has a reasonable structural design and is easy to use. It uses a snap-fit ​​method to fix the polishing roller. When it is damaged after long-term use and needs to be replaced, it can be quickly removed and replaced without the aid of tools. The quick-release design can also install polishing rollers of different diameters, thus adapting to the use of anti-oxidation graphite tubes with different inner diameters, making it highly applicable.

[0029] Working principle: When the polishing roller body 63 needs to be removed and replaced, first rotate the locking screw 58 so that its end is disengaged from the connecting sleeve 51. The push spring 510 will push the sliding sleeve 53 and the moving ring 54 to move vertically upward under the limit of the guide rod 52, thereby driving the Y-shaped locking frame 55 to move upward and disengage it from the rotating block 66. At this time, the rotating block 66 can be rotated under the connection of the fixed shaft 65 until it coincides with the insertion port 59. Then the mounting base 61 can be pulled down from the connecting sleeve 51, thereby removing the polishing roller body 63. Similarly, when installing, simply reverse the above steps.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
