Description

Technical Field

[0001] The present invention relates to the technical field of crucible trimming, and specifically refers to a graphite crucible trimming device. Background Art

[0002] Graphite crucibles are mainly made of graphite as the main raw material and processed through a specific process. They have a specific shape and structure and are used to hold and process various substances in a high-temperature environment. The production process generally involves starting a rotary canning machine, making it reach a set rotational speed, and then uniformly feeding materials into the mold. When the set forming time is reached and the crucible is fully cured, the rotary canning machine is stopped and demolding is carried out after that.

[0003] In the existing technology, during the forming production process of graphite crucibles, the situation of graphite crucible deformation may occur. For example, the rotational speed is unstable, the mold wears, etc. When the rotational speed of the rotational molding equipment is unstable during operation, the centrifugal force received by the material will be uneven. Uneven material distribution will cause the thickness of each part of the crucible to be inconsistent, and after the mold is used for a long time, wear will appear on the surface, resulting in a decrease in the dimensional accuracy of the mold. This will cause the size of the formed crucible to not meet the design requirements and the shape to be irregular, and thus it is prone to deformation.

[0004] In the existing technology, when trimming a deformed graphite crucible, generally, a cutting device is manually used to cut off the excess part of the graphite crucible and then polished, and manual feeding is carried out for the thin and less parts to achieve the trimming work of the graphite crucible. However, when manually operating the cutting device, due to the inability to accurately position the cutting point, the situation of cutting too much of the graphite crucible may occur, and the trimming operation also requires trimming the inner and outer end faces of the graphite crucible in sequence, resulting in low trimming efficiency of the graphite crucible.

[0028] Combined with the attached Figure 1 attachment Figure 2 attachment Figure 3 as shown: A graphite crucible trimming device, including a device box body 1.

[0029] The working principle of the present invention: The crucible body 2 is a graphite crucible. The pressing structure 21 can fix the crucible body 2 inside the device box body 1. The grinding driving mechanism 31 drives the inner grinding mechanism 51 and the outer grinding mechanism 61 to rotate simultaneously through the upper transmission structure 41 and the lower transmission structure 42. During the rotation of the inner grinding mechanism 51 and the outer grinding mechanism 61, they move in opposite directions driven by the adjusting mechanism 71, and the crucible body 2 can be ground during the process. During the grinding process, the dust removal device 91 can extract dust particles. Then, the graphite paste extrusion structure 81 extrudes the graphite paste to repair the missing part of the crucible body 2.

[0030] Combined with the attached Figure 2 attachment Figure 3 attachment Figure 4 as shown: The support member includes a lower lead screw 214 rotatably provided at the bottom of the device box body 1.

[0031] Place the crucible body 2 on the top block 215. During the process, it is necessary to make the base of the crucible body 2 coincide with the top block 215. Then, manually rotate the upper lead screw 211 by adjusting the end one 213. The downward movement of the upper lead screw 211 causes the pressing block 212 to move downward and extend into the crucible body 2. When it moves to contact and press against the inner base of the crucible body 2, the crucible body 2 is in a fixed state.

[0032] Combined with the attached Figure 3 、attached Figure 4 、attached Figure 5 、attached Figure 6 、attached Figure 7 、attached Figure 8 as shown in: The grinding drive mechanism 31 includes a drive motor 311 fixed to the equipment box body 1. The drive wheel on the drive motor 311 drives the rotation of a runner 313 located inside the equipment box body 1 through a belt 314.

[0033] When grinding the crucible body 2, start the drive motor 311 to drive the rotation of the runner 313 through the belt 314. The runner 313 drives the rotation of the upper drive rod 312. The upper drive rod 312 drives the rotation of the upper transmission structure 41. The upper transmission structure 41 drives the rotation of the inner grinding mechanism 51; When the upper drive rod 312 rotates, it drives the rotation of the rack two 317 through the rack one 315. The rack two 317 drives the rotation of the lower drive rod 316. The lower drive rod 316 drives the rotation of the lower transmission structure 42. The lower transmission structure 42 drives the outer grinding mechanism 61. The rotation directions of the inner grinding mechanism 51 and the outer grinding mechanism 61 are opposite; Afterwards, manually adjust the adjusting mechanism 71 to drive the internal grinding mechanism 51 and the external grinding mechanism 61 to move in opposite directions simultaneously. During grinding, the internal grinding mechanism 51 and the external grinding mechanism 61 gradually approach. When the internal grinding parts 515 on the internal grinding mechanism 51 and the external grinding parts 612 on the external grinding mechanism 61 gradually come into contact with the crucible body 2, the crucible body 2 can be ground. In the present invention, the contact surfaces of the internal grinding parts 515 and the external grinding parts 612 with the crucible body 2 are both diamond sand cylinders, and the material is the same as that of the diamond grinding wheel in the prior art.

[0034] Combined with the attached Figure 3 、attached Figure 4 、attached Figure 5 、attached Figure 6 as shown: The adjusting mechanism 71 includes a rotating rod 711 rotatably arranged in the equipment box body 1. A first bevel gear 719 is fixed on the rotating rod 711. A second bevel gear 720 is meshed on one side of the first bevel gear 719. The rotating shaft of the second bevel gear 720 passes through the side wall of the equipment box body 1 and an adjusting end 721 is provided at the end. The first gear assembly includes a first driving gear 712 clamped with the rotating rod 711 and capable of moving axially along the rotating rod 711. A first driven gear 714 meshed with the first driving gear 712 is threadedly sleeved on the upper lead screw 211. A connecting member 713 with one end sleeved on the upper lead screw 211 is rotatably arranged on the first driven gear 714. The other end of the connecting member 713 is sleeved on the rotating rod 711 and is rotatably connected with the first driving gear 712. A connecting member 414 is jointly rotatably connected between the first driving wheel 411 and the first driven wheel 412. The connecting member 414 is rotatably connected with the first driven gear 714.

[0035] The second gear assembly includes a second driving gear 715 clamped with the rotating rod 711 and capable of moving axially along the rotating rod 711. A second driven gear 717 meshed with the second driving gear 715 is threadedly sleeved on the lower lead screw 214. A connecting member 716 with one end sleeved on the lower lead screw 214 is rotatably arranged at the bottom of the second driven gear 717. The other end of the connecting member 716 is sleeved on the rotating rod 711 and is rotatably connected with the first driving gear 712. A connecting member 424 is jointly rotatably connected at the bottom between the second driving wheel 421 and the second driven wheel 422. The connecting member 424 is rotatably connected with the second driven gear 717.

[0036] After starting the drive motor 311, manually rotate the second bevel gear 720 by adjusting the second end 721. The second bevel gear 720 drives the rotating rod 711 to rotate through the first bevel gear 719. When the rotating rod 711 rotates, it can drive the first gear assembly and the second gear assembly to work simultaneously. In the first gear assembly, the first driving gear 712 drives the first driven gear 714 to rotate. During the rotation of the first driven gear 714, it gradually moves towards the crucible body 2. At this time, the first driven gear 714 drives the first driving gear 712 to move through the first connecting piece 713, and at the same time drives the first main transmission wheel 411 and the first driven transmission wheel 412 to move simultaneously through the third connecting piece 414; In the second gear assembly, the second driving gear 715 drives the second driven gear 717 to rotate. During the rotation of the second driven gear 717, it gradually moves towards the crucible body 2. At this time, the second driven gear 717 drives the second driving gear 715 to move through the second connecting piece 716, and at the same time drives the second main transmission wheel 421 and the second driven transmission wheel 422 to move simultaneously through the fourth connecting piece 424.

[0037] Combined with the attached Figure 3 、attached Figure 4 、attached Figure 9 as shown: The dust removal device 91 includes a fan device 911 fixed to the rear end of the equipment box body 1. The input end of the fan device 911 is connected to a pipe fitting 912. The pipe fitting 912 is connected to an air inlet port 913 on the inner wall of the equipment box body 1, and telescopic pipes 914 are connected to both the upper and lower ends. The upper telescopic pipe 914 is sleeved outside the upper lead screw 211 and is connected between the equipment box body 1 and the first connecting piece 713. The lower telescopic pipe 914 is sleeved outside the lower lead screw 214 and is connected between the equipment box body 1 and the second connecting piece 716. A number of second through grooves 718 are provided on both the first driven gear 714 and the second driven gear 717.

[0038] When the inner grinding mechanism 51 and the outer grinding mechanism 61 grind the crucible body 2, start the fan device 911. At this time, the dust particles generated by grinding can be extracted by the fan device 911 through the pipe fitting 912 and the air inlet port 913. During the movement of the inner grinding mechanism 51 and the outer grinding mechanism 61, the telescopic pipe 914 is stretched. The dust particles inside the crucible body 2 enter the top of the pipe fitting 912 through the inner grinding mechanism 51, the upper transmission structure 41, and the second through grooves 718 on the first gear assembly; The dust particles located outside the crucible body 2 and between the outer grinding mechanism 61 enter the bottom end of the pipe fitting 912 through the outer grinding mechanism 61, the lower transmission structure 42, and the second through grooves 718 on the second gear assembly.

[0039] Combined with the attached Figure 3 、attached Figure 4 、attached Figure 5 as shown: The graphite paste extrusion structure 81 includes a conveying pipe 811 located at the top of the equipment box body 1 and capable of conveying graphite paste. An extrusion pipe 812 passing through the equipment box body 1 is inserted into the conveying pipe 811. The bottom end of the extrusion pipe 812 is fixedly passed through a third connecting member 414 and is communicated with an end pipe 813 at the bottom end. There is an annular groove 512 on the turntable 511, and a number of first through grooves 513 are provided on the annular groove 512. The output end of the end pipe 813 is located directly above the first through grooves 513.

[0040] During grinding, the driving motor 311 needs to work at a high speed. After grinding, the driving motor 311 rotates slowly at a low speed. In the present invention, the graphite paste needs to be extruded, that is, the graphite paste material is loaded into the paste cylinder of a press and extruded. The press is a prior art and will not be described in detail in the present invention. While the driving motor 311 rotates slowly at a low speed, the graphite paste is conveyed from the conveying pipe 811 through the extrusion pipe 812 to the end pipe 813 and is output from the end pipe 813 into the gap between the inner grinding mechanism 51 and the outer grinding mechanism 61. Since the relative position between the end pipe 813 and the crucible body 2 is fixed at this time, the graphite paste needs to be discharged slowly. During the process, the rotating turntable 511 will move the excess graphite paste on the annular groove 512 to the position where replenishment is not required. At this time, the trimming of the crucible body 2 is completed. After the trimming is completed, a small amount of graphite paste will adhere to the inner grinding member 515 and the outer grinding member 612 on the inner grinding mechanism 51 and the outer grinding mechanism 61. When the adhered graphite paste affects the subsequent grinding work, the staff still needs to mechanically clean the inner grinding member 515 and the outer grinding member 612, such as using a brush. In the present invention, the connection methods between the first mounting seat 514 and the second mounting seat 611 and between the inner grinding member 515 and the outer grinding member 612 are all to set locking bolts on the first mounting seat 514 and the second mounting seat 611 that abut against the inner grinding member 515 and the outer grinding member 612. When cleaning the inner grinding member 515 and the outer grinding member 612, they can be disassembled by loosening the locking bolts.

[0041] When using the graphite crucible trimming equipment provided by the present invention to trim a graphite crucible: The crucible body 2 is fixed in the equipment box body 1 through the pressing structure 21. The grinding driving mechanism 31 is started to drive the inner grinding mechanism 51 and the outer grinding mechanism 61 to rotate simultaneously through the upper transmission structure 41 and the lower transmission structure 42. During the rotation of the inner grinding mechanism 51 and the outer grinding mechanism 61, the manual operation adjustment mechanism 71 drives the inner grinding mechanism 51 and the outer grinding mechanism 61 to move in opposite directions. During the process, the inner grinding mechanism 51 and the outer grinding mechanism 61 can grind the inner and outer end faces of the crucible body 2. During the grinding process, the dust removal device 91 can extract dust particles. Then, the graphite paste extrusion structure 81 extrudes the graphite paste to repair the missing part of the crucible body 2 to complete the trimming work of the crucible body 2.

[0042] The above describes the present invention and its embodiments. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In general, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
