[0002] The main component of the spring tube pressure gauge is a spring tube bent into an arc shape, and the cross section of the tube is elliptical. One end of the spring tube as a measuring element is fixed and connected to the measured medium through a joint; the other end is closed and is a free end. The free end is connected to the connecting rod and the fan gear, and the fan gear meshes with the core gear to form a transmission amplification device.
[0003] When using the existing automated welding device for the pressure gauge spring tube, a lot of energy and physical strength are needed to manually fix and adjust the pressure gauge.
