[0022] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0023] A high-precision quartz tube clamping fixture includes a processing table 1. A clamping assembly 2 is connected to one side of the processing table 1. The clamping assembly 2 includes two mounting slots 201. Two pressure bearings 202 are embedded in the inner wall of each mounting slot 201. A rotating screw 203 is connected to the inner ring of each set of pressure bearings 202. A geared motor 204 is connected to one end of each rotating screw 203. A connecting block 205 is threaded onto the outer surface of each rotating screw 203. A clamping plate 206 is connected to one side of each connecting block 205. The fixture is designed to be used for clamping quartz tubes. The workbench 1 facilitates the processing of high-precision quartz tubes. In conjunction with the rotation of the geared motor 204, it drives the rotating screw 203 to rotate within the inner ring of the pressure bearing 202. Furthermore, the rotating screw 203 is threadedly connected to the connecting block 205, and the connecting block 205 is slidably connected to the mounting groove 201. This allows the two connecting blocks 205 to bring the two clamping plates 206 closer together, clamping and positioning the high-precision quartz tube to be processed. This ensures that the high-precision quartz tube is centered during processing, avoiding any impact on the processing accuracy of the high-precision quartz tube.

[0024] In this embodiment, each clamping plate 206 has a protective pad 8 connected to one side, and each protective pad 8 has anti-slip texture on one side. The protective pad 8 protects the high-precision quartz tube, preventing collisions and increasing its safety. Two protective strips 9 are connected to one side of the processing table 1, and a set of support legs 12 are also connected to one side of the processing table 1. The protective strips 9 prevent the high-precision quartz tube from colliding with the processing table 1, improving processing quality. The support legs 12 provide convenient support for the equipment and reduce the probability of slippage. Two protective strips 9 are connected to one side of the processing table 1. Each slide groove 10 has a slider 11 slidably connected to its inner wall. One side of each slider 11 is connected to one side of the clamping plate 206. The sliding connection between the slider 11 and the slide groove 10 increases the stability of the clamping plate 206, preventing it from shifting and increasing its processing accuracy. One side of the clamping plate 206 is connected to a positioning rod 6, and an infrared measuring instrument 7 is installed on one side of the positioning rod 6. Using the positioning rod 6 and the infrared measuring instrument 7, the accuracy of the high-precision quartz tube can be measured, and the levelness of the clamping plate 206 can be easily detected, avoiding poor accuracy.

[0025] In this embodiment, a fixing bracket 3 is connected to the outer surface of each geared motor 204, and one side of each fixing bracket 3 is connected to one side of the processing table 1. The fixing bracket 3 increases the stability of the geared motor 204, prevents it from becoming loose, and improves the service life of the geared motor 204. A lighting lamp 5 is installed on one side of each clamping plate 206, and the outer surface of each connecting block 205 is slidably connected to the inner wall of the mounting groove 201. The lighting lamp 5 can conveniently provide supplementary lighting for the operator, avoiding the situation where poor visibility affects the processing quality, and also reducing the probability of accidents. A control switch 4 is connected to one side of the processing table 1, and the outer surface of each geared motor 204 is connected to one side of the processing table 1. The control switch 4 can conveniently control and set the operation of the electrical components, avoiding the situation where they are inconvenient to operate.

[0026] Working principle: First, transport it to the location of use and connect the electrical components to the power supply. Then, set and control the required program by pressing the external control switch 4. At the same time, place the raw material to be processed on the two protective strips 9. Then, start the infrared measuring instrument 7 to detect the levelness of the raw material and the clamping plate 206. Then, turn on the lighting 5 to provide supplemental lighting for the personnel as needed, and start the two geared motors 204. The rotation of the geared motors 204 causes the rotating screw 203 to rotate. At the same time, the rotating screw 203 is threadedly connected to the connecting block 205 and the connecting block 205 is slidably connected to the mounting groove 201. This allows the two connecting blocks 205 to drive the two clamping plates 206 to move closer to each other, fixing the raw material to be processed and centering it. Finally, process it. The above is the complete usage process of this utility model.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
