Description

Technical Field

[0001] The utility model belongs to the technical field of quartz tube production equipment, and in particular relates to a clamping device for producing large-diameter quartz tubes. Background Art

[0002] Quartz tube is a special industrial technical glass made of silicon dioxide, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties, and is often used in electric fire buckets, electric stoves, and electric heaters to generate heat. Large-diameter quartz tube refers to a quartz pipe with a larger diameter. Large-diameter quartz tube is an indispensable equipment component in the oxidation and diffusion process of wafers and photovoltaic panels.

[0003] Chinese patent CN216073548U discloses a clamping device for producing large-diameter quartz tubes, which belongs to the technical field of quartz tube production equipment. The clamping device for producing large-diameter quartz tubes comprises: a base, a motor is fixedly connected to one end of the outer wall of the base, a bidirectional threaded shaft is fixedly connected to the output end of the motor, a first pneumatic telescopic rod is threadedly connected to the bidirectional threaded shaft, a fixing plate is fixedly connected to the top of the first pneumatic telescopic rod, a threaded rod is rotatably connected inside the fixing plate, and a clamping block is threadedly connected to the threaded rod.

[0004] With the development of the industry, the size of quartz tubes continues to expand, and it is no longer possible to load them manually alone. Therefore, a clamping device is needed to clamp large-diameter quartz tubes. However, traditional mechanical clamping equipment is not suitable for clamping large-diameter quartz tubes because the quartz tubes are brittle and easy to break, and the surface is easily scratched. In the above document, the first spring and the movable rod are used to prevent the extrusion force from being too large, which may cause damage to the quartz tube; the threaded rod is rotated to drive the clamping block to open and adjust the length to match the diameter of the quartz tube. However, when placing the quartz tube, first place one end of the quartz tube on the clamping block, and then push the other end of the quartz tube to slide on the surface of the clamping block until the clamping block can support the entire quartz tube. During this process, the friction between the quartz tube and the surface of the clamping block is large, which can easily cause the surface of the quartz tube to be scratched.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
