Description

Technical Field

[0001] The invention belongs to the technical field of quartz crucible grinding, and in particular relates to a quartz crucible grinding device. Background Art

[0002] Quartz crucible is a high temperature resistant container made of high purity quartz sand through high temperature melting, molding and processing. They are usually used in industrial processes that require high temperature treatment, such as metal smelting, growth of semiconductor materials, preparation of optical materials, and chemical experiments. During the manufacturing process of quartz crucible, some surface defects such as scratches, unevenness or tiny cracks may occur. Grinding can remove these defects, ensure the smooth surface of the crucible, and reduce stress concentration points that may be caused during use. When the quartz crucible is used in subsequent high temperature or chemical reaction environments, the smoothness of the surface directly affects its heat resistance and chemical stability. By grinding, the microcracks and roughness of the surface can be reduced, thereby improving its performance in high temperature or chemical environments.

[0003] Since the quartz crucible is U-shaped, and the inner wall and part of the bottom are curved surfaces, it is difficult to fix it during grinding. This can easily cause the quartz crucible to deviate during the grinding process and fail to be fully polished, thus affecting the overall quality of the quartz crucible. Summary of the invention

Through the function of the adjusting shell, the device can flexibly adjust the position of the supporting shell, so that the device can efficiently grind quartz crucibles of different specifications, and it is convenient for the grinding disc to contact the quartz crucible more fully. Moreover, through the supporting shell that can adjust the positive and negative positions, whether it is the inner wall or the outer wall of the quartz crucible that is being ground, it can be fixed stably and quickly, which is more convenient for the staff to carry out subsequent grinding work, and solves the problem that the existing quartz crucible is difficult to fix during grinding because the quartz crucible is U-shaped and the inner wall and part of the bottom are curved surfaces, which easily causes the quartz crucible to deviate during the grinding process and cannot be fully polished.

Specific embodiment 1

[0049] See also Figure 1-9 The present invention is a quartz crucible grinding device, comprising a processing table 1, with adjustment grooves 2 fixed on both sides of the processing table 1; an adjustment block 3 is slidably connected inside the adjustment groove 2, a support frame 4 is fixed on one side of the adjustment block 3, and a slide groove 5 is opened on the top of the support frame 4; a grinding mechanism 6 is slidably connected inside the slide groove 5; an adjustment shell 7 is fixed on the surface of the processing table 1, a first motor 8 is fixed on the bottom of the adjustment shell 7, and a threaded rod 9 is fixed on the output shaft of the first motor 8; the output shaft of the first motor 8 passes through the adjustment shell 7, and the outer ring of the threaded rod 9 is threadedly connected to a threaded tube 10; the outer ring of the threaded tube 10 A first bearing 11 is fixed, and a support rod 12 is fixed to the outer ring of the first bearing 11; a base plate 13 is fixed to one end of the support rod 12, and a positioning plate 14 is fixed to the upper surface of the base plate 13; a second bearing 15 is fixed to the inner wall of the positioning plate 14, an adjustment plate 16 is fixed to the inner ring of the second bearing 15, and a support shell 17 is fixed to the inner wall of the adjustment plate 16; a plurality of positioning holes 18 are opened on the surface of the adjustment plate 16, a tension spring 19 is fixed to one side of the positioning plate 14, and a handle 20 is fixed to one end of the tension spring 19; a clamping rod 21 is fixed to one end of the handle 20, and the clamping rod 21 passes through the positioning plate 14.

[0050] Specifically, a limiting hole 22 is formed on the surface of the adjustment plate 16 ; a limiting rod 23 is fixed on the outer side of the support rod 12 , and the limiting rod 23 passes through the limiting hole 22 .

[0051] Furthermore, the inner wall of the adjusting groove 2 is a “T”-shaped structure, and the inner wall of the adjusting groove 2 matches the adjusting block 3 .

[0052] The operation process of this embodiment is as follows: when the device is in use, the height of the support shell 17 is first adjusted according to the size of the quartz crucible that needs to be polished, that is, the first motor 8 is turned on, and the output shaft of the first motor 8 drives the threaded rod 9 at one end thereof to rotate. When the threaded rod 9 rotates, it drives the threaded tube 10 on the outside thereof to rotate, and the threaded tube 10 drives the first bearing 11 on the outside thereof to move upward. Since the inner ring of the first bearing 11 is fixedly connected to the threaded tube 10, and the outer ring of the first bearing 11 is fixedly connected to the support rod 12, based on the fact that the inner ring and the outer ring of the bearing can rotate relatively, when the threaded tube 10 rotates, the support rod 12 is limited by the limiting rod 23 at one end of the support rod 12, and the support rod 12 moves upward stably;

[0053] When the support rod 12 drives the bottom plate 13 and the support shell 17 at the top thereof to move to a suitable position, the position of the support shell 17 is adjusted according to the part of the quartz crucible that needs to be polished. That is, if the outside of the quartz crucible needs to be polished, the handle 20 is pulled, and the handle 20 drives the clamping rod 21 at one end thereof to move, so that the clamping rod 21 falls off from the positioning hole 18, and then the support shell 17 is rotated 180 degrees, so that the arc surface of the support shell 17 faces upward and the cavity faces downward. At this time, the quartz crucible can be turned upside down on the support shell 17, which is convenient for polishing the outer wall of the quartz crucible. When the inner wall of the quartz crucible needs to be polished, When grinding the wall, the cavity of the support shell 17 is facing upwards, and the quartz crucible is placed in the support shell 17, so that the inner wall of the quartz crucible can be ground; the device can flexibly adjust the position of the support shell 17, so that the device can efficiently grind quartz crucibles of different specifications, and it is convenient for the grinding disc 607 to contact the quartz crucible more fully. Moreover, by adjusting the positive and negative positions of the support shell 17, whether it is the inner wall or the outer wall of the quartz crucible that is being ground, it can be stably and quickly fixed, which is more convenient for the staff to carry out subsequent grinding work. Specific embodiment 2

[0055] See also Figure 3-5 On the basis of the specific embodiment 1, a plurality of dust collecting holes 24 are formed on the bottom plate 13 and one side of the adjusting shell 7, and a sealing groove 25 is formed on one side of the adjusting shell 7; a sealing strip 26 is movably connected inside the sealing groove 25, and a connecting plate 27 is fixed on one side of the sealing strip 26.

[0056] Specifically, the connecting plate 27 is connected to the collecting box 28 via a first air duct, and the collecting box 28 is connected to the air pump 29 via a second air duct.

[0057] Furthermore, a plurality of mounting grooves 30 are formed on the top of the collecting box 28 , and dustproof plates 31 are movably connected inside the mounting grooves 30 .

[0058] The operation process of this embodiment is as follows: during the grinding of the quartz crucible, the vacuum pump 29 can be turned on, and the vacuum pump 29 will suck the dust dropped during the grinding of the quartz crucible into the collection box 28 through the dust collecting hole 24. The several dustproof plates 31 in the collection box 28 are activated carbon plates, which can effectively adsorb the dust generated during the grinding process. The device can prevent the dust from floating in the processing site and prevent the dust from being inhaled by the staff, thereby protecting the health of the staff. At the same time, the dust on the grinding surface is removed to prevent the dust from adhering to the surface of the workpiece again, so as to ensure that the surface of the quartz crucible after grinding is smoother and cleaner, thereby improving the final grinding quality.

[0062] The operation process of this embodiment is as follows: the position of the grinding mechanism 6 can be flexibly adjusted by the support frame 4 that can be moved above the processing table 1, so that the grinding mechanism 6 can be adjusted according to the position of the quartz crucible. When the grinding disc 607 needs to be polished downward, the grinding mechanism 6 can be moved to a suitable position by the adjustment block 3 and the connecting block 601, and then the movable plate 603 is pressed downward, and the movable plate 603 drives the connecting rod 604 to move downward. The second motor 606 at one end of the connecting rod 604 works to drive the grinding disc 607 to rotate, and the grinding disc 607 polishes the quartz crucible. The device can flexibly adjust the position of the grinding mechanism 6 on the processing table 1, which is not only convenient for comprehensive polishing of the quartz crucible, but also convenient for the staff to install and take the quartz crucible in time.
