Description

Technical Field

[0001] The utility model belongs to the technical field of detection fixtures, and particularly relates to a flange fixing device for welding flanges. Background Art

[0002] A flange, also known as a flange boss plate or a flange. A flange is a part used for connecting pipes to each other and is used for connecting the pipe ends; there are also flanges used at the inlets and outlets of equipment for connecting two pieces of equipment, such as a reducer flange. A flange connection or a flange joint refers to a detachable connection formed by connecting a flange, a gasket, and bolts as a set of combined sealing structures.

[0003] Currently, the Chinese utility model with the publication number CN211362008U discloses a fixture for engine piston detection, which includes a mounting plate. A pair of slide rails are installed on the mounting plate, a pair of sliders are arranged on the pair of slide rails, a pair of limiting components are installed on the pair of sliders, a vertical plate is installed on the mounting plate, a threaded rod is movably installed on the vertical plate, and an adjusting block is screwed on the threaded rod. The structure of this device is compact. By rotating the adjusting bolt, a pair of clamping plates clamp the piston rod. When the position of the piston rod needs to be adjusted, rotate the adjusting wheel, and the adjusting block drives the two sliders to move through the connecting rod, thereby completing the position adjustment of the piston rod. The lock hole on the adjusting wheel cooperates with the telescopic lock rod to fix the adjusting wheel and prevent the adjusting block from moving during the measurement process, enhancing the safety of the device and bringing convenience to people's use.
