Description

Technical Field

[0001] The present application relates to the technical field of quartz tube processing, and in particular to a cutting machine for small quartz tubes. Background Art

[0002] Quartz tubes have excellent physical and chemical properties, such as high temperature resistance, strong corrosion resistance, and good light transmittance. Small quartz tubes play an important role in many fields. In scientific research, they are often used to build some special experimental environments. Their stable performance ensures the accuracy and reliability of experimental results. In industrial production, small quartz tubes can be used in certain precision machining processes. At the same time, the processing of small quartz tubes is also particularly important. Therefore, there is an urgent need for a small quartz tube cutting machine in the market.

[0003] According to the announcement number: CN 214982260 U, a cutting machine for small quartz tubes is disclosed. This technology discloses "including a frame, the frame including support legs and a support frame placed on one side of the upper end surface of the support legs, a placement plate connected to the support frame, one end of the placement plate is rotatably connected to the support frame, and the other end is provided with a placement groove, the cross-section of the placement groove is a "V"-shaped structure, and a cutting tool is also provided on the other side of the upper end surface of the support leg, the placement groove extends outside the placement plate and extends through the cutting tool, the placement groove is provided with a through groove at the contact point between the tool and the placement groove, and the width of the through groove is greater than the thickness of the cutting tool; the quartz tube is placed in the placement groove, the position to be cut is placed in the through groove for cutting, and if cutting is required to continue after the cutting is completed, the quartz tube is pushed forward to a certain position, and then the cutting is continued, and the blade is smooth and will not be disordered. The technical solution has the advantages that when continuously cutting, only the quartz tube needs to be moved forward, and no other operations are required. The overall operation is very simple, no time is wasted, and the cutting is relatively fine.

[0004] Regarding the above-mentioned related technologies, the inventor believes that most existing small quartz tubes use clamps to fix the quartz tubes from both ends when cutting and fixing. However, since the quartz tubes are too brittle as a whole, they are easily damaged during fixation, resulting in a waste of resources. Secondly, when existing quartz tube workers cut them, due to the material of the quartz tubes, excessive debris and dust are easily generated during cutting, which can easily cause workers to inhale these dusts, affecting their respiratory health.

[0005] In view of the above-mentioned related technologies, the inventor believes that a small quartz tube cutting machine is needed to solve the above-mentioned problems. Utility Model Content
