Description

Technical Field

[0001] The utility model relates to a six-claw device, in particular to an adjustable six-claw device for melting a quartz crucible. Background Art

[0002] In equipment used to melt quartz materials, a six-claw mechanism securely holds the quartz crucible, preventing it from shifting or tilting under the effects of high temperatures and gravity, ensuring a safe and efficient melting process. The six-claw mechanism typically consists of six copper rods arranged around a central point, forming a hexagonal structure. Each rod can move radially—toward or away from the center—to precisely secure the quartz crucible.

[0003] However, in actual use, the copper rods or their adjustment mechanisms may wear out or malfunction over time, resulting in the center of the circle not being aligned after adjustment. In the prior art, if this happens, the six copper rods must be disassembled and their center points recalibrated, as they can only move synchronously. This approach is not only extremely cumbersome but also severely impacts the quartz material smelting process and reduces production efficiency. Utility Model Content

[0004] In order to overcome the disadvantage in the prior art that when the copper pole has a fixed point problem, it needs to be disassembled for maintenance, which affects normal use, the technical problem of the utility model is to provide an adjustable six-claw device for melting a quartz crucible.

[0005] The technical implementation scheme of the present utility model is: an adjustable six-claw device for melting a quartz crucible, comprising a mounting seat, a fixed frame, a cylinder, a lifting frame, a rotating frame, a movable frame, an articulated frame, a fixed frame, a copper pole and a positioning assembly. A fixed frame is installed on the front side of the mounting seat, a cylinder is installed on the top of the fixed frame, the cylinder telescopic rod extends into the fixed frame and is connected to the lifting frame, six rotating frames are evenly rotatably connected along the outer side of the lifting frame, movable frames are installed on the rotating frames, the lower ends of the movable frames are rotatably connected to the articulated frames, the lower ends of the articulated frames are rotatably connected to the fixed frames, the fixed frames are connected to the bottom of the mounting seat, copper poles are installed on the outer sides of the articulated frames, and a positioning assembly is provided on the fixed frame.

[0006] Furthermore, the six-claw device also includes fastening screws, and the movable frame and the rotating frame are threadedly connected via two fastening screws.

[0007] Furthermore, the positioning assembly includes a motor, a screw, a lifting plate and a guide rod. The motor is installed in the fixed frame, the screw is connected to the motor output shaft, the lifting plate is threadedly connected to the screw, the guide rods are symmetrically connected to the bottom of the fixed frame, and the lifting plate is slidably connected to the two guide rods.

[0008] Furthermore, six positioning grooves are provided at intervals along the circumference of the outer side of the lifting plate, and the copper poles are engaged with the positioning grooves.

[0009] Furthermore, a heat insulation layer is provided on the outer side of the lower end of the copper pole.

[0010] Furthermore, each movable frame is also equipped with a fine-tuning screw for performing fine position adjustment, and the fine-tuning screw is threadedly connected to the rotating frame.

[0011] The utility model has the following advantages: the rotating frame and the movable frame are installed by sliding and fixed by fastening screws. When the centers of the six copper poles are not at the same center point, the movable frame can be adjusted by sliding to achieve individual adjustment of the copper poles, thereby achieving six-point positioning. Not only is the operation simple and fast, but the positioning accuracy and reliability are improved, providing great convenience for the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] Example: A quartz crucible melting adjustable six-claw device, such as Figures 1-4As shown, it includes a mounting base 1, a fixed frame 2, a cylinder 3, a lifting frame 4, a rotating frame 5, a movable frame 6, a fastening screw 7, an articulated frame 8, a fixed frame 9, a copper pole 10 and a positioning assembly. The front side of the mounting base 1 is fixed with a fixed frame 2 by bolts, and the top of the fixed frame 2 is fixed with a cylinder 3 by bolts. The telescopic rod of the cylinder 3 extends into the fixed frame 2 and is connected to the lifting frame 4. Six rotating frames 5 are evenly connected to the outer side of the lifting frame 4 along the circumference. The movable frames 6 are installed on the rotating frames 5, and the movable frames 6 and the rotating frames 5 are respectively connected. It is threadedly connected by two fastening screws 7. Each movable frame 6 is also equipped with a fine-tuning screw for fine position adjustment. The fine-tuning screw is threadedly connected to the rotating frame 5. The lower end of the movable frame 6 is rotatably connected to the articulated frame 8. The lower end of the articulated frame 8 is rotatably connected to the fixed frame 9. The fixed frame 9 is connected to the bottom of the mounting base 1. Copper poles 10 are installed on the outside of the articulated frame 8. The outer side of the lower end of the copper pole 10 is provided with a heat insulation layer to reduce heat conduction and protect the operator and equipment from high temperature. A positioning component is provided on the fixed frame 9.

[0019] like Figure 1 and Figure 4 As shown, the positioning assembly includes a motor 11, a screw 12, a lifting plate 13 and a guide rod 14. The motor 11 is installed in the fixed frame 9 by bolts. The screw 12 is connected to the output shaft of the motor 11, and the lifting plate 13 is threadedly connected to the screw 12. The guide rods 14 are welded symmetrically on the bottom of the fixed frame 9. The lifting plate 13 is slidably connected to the two guide rods 14. Six positioning grooves are provided at intervals along the circumference of the outer side of the lifting plate 13. The copper pole 10 is engaged with the positioning groove to ensure that the copper pole 10 is at a center point.

[0020] In the equipment for melting quartz materials, the six-claw device is installed and fixed by the mounting base 1. The six-claw device is mainly used to fix and support the quartz crucible. During operation, first determine the adjustment range of the copper pole 10 according to the diameter of the quartz crucible, and adjust the height of the lifting plate 13 at the same time to ensure that the copper pole 10 can be accurately engaged with the positioning groove on the lifting plate 13 when it is reduced to the preset diameter. During specific operation, start the motor 11, and the output shaft of the motor 11 rotates to drive the screw 12 to rotate, that is, drive the lifting plate 13 to move upward along the guide rod 14. Similarly, control the motor 11 to run in the opposite direction, which drives the screw 12 to reverse, and then drives the lifting plate 13 to move downward along the guide rod 14, which will lower the height of the lifting plate 13. After the height is adjusted to the preset value, turn off the motor 11, and then start the gas. Cylinder 3, the telescopic rod of cylinder 3 extends to drive the lifting frame 4 to move downward, and the lifting frame 4 pushes the rotating frame 5 and the movable frame 6 to rotate outward, and the movable frame 6 drives the articulated frame 8 to rotate inward, so as to drive the copper pole 10 to move inward, and the center of the circle is reduced. The copper pole 10 is adjusted to be engaged with the positioning groove on the lifting plate 13. After adjustment, the cylinder 3 is closed. If some copper poles 10 are not engaged with the positioning groove after shrinking to the preset value and are not at a center point, the corresponding fastening screws 7 can be loosened separately, and the articulated frame 8 can be driven to rotate by telescoping the movable frame 6 to adjust the angle of the copper pole 10 separately, so that the copper pole 10 is adjusted to be engaged with the positioning groove, thereby achieving six-point positioning. After adjustment, the fastening screws 7 are tightened again, so that the quartz crucible can be fixed and supported by the copper pole 10. If it is necessary to release the copper pole 10 from the quartz crucible, control the telescopic rod of the cylinder 3 to shorten and reset, drive the lifting frame 4 to move upward, drive the rotating frame 5 and the movable frame 6 to reverse, and drive the articulated frame 8 and the copper pole 10 to rotate and expand outward, loosen the fixation on the quartz crucible, and then close the cylinder 3.
