[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. It is used in electric fire buckets, electric stoves, and electric heaters to generate heat. During the processing of quartz tube, there will be some burrs on the inner wall, which needs to be polished.

[0003] At present, when grinding the inner wall of a quartz tube, it is usually done manually or with a grinding device. However, when grinding manually, the quartz tube needs to be held manually for grinding, which not only has a large workload but also has poor grinding precision. If grinding is done with a grinding device, the existing grinding device can usually only grind quartz tubes of one size, and it is difficult to grind the inner walls of quartz tubes of different sizes. The grinding head needs to be replaced, and the use is limited. For this reason, we designed a quartz tube inner wall grinding device to solve the above problems. Utility Model Content

The two rack plates 15 are respectively located on the left and right sides of the gear 14 and are meshed with the gear 14, so that when the gear 14 rotates, the two rack plates 15 can be moved in opposite directions under the meshing action thereof. The first transmission belt 17 is wound between the rotating shafts of the two gears 14 on the two adjusting components, so that the two gears 14 can rotate synchronously;
