Pressure gauge shell assembling machine with torsion detection function

The utility model discloses a pressure gauge case assembling machine for torsion detection, and belongs to the technical field of pressure gauges. The utility model discloses a pressure gauge shell assembling machine for torsion detection. The pressure gauge shell assembling machine comprises a circular connecting plate and a double-layer circular rotating groove formed in the center of the bottom of the circular connecting plate. A circular opening communicated with the center of the top of the circular connecting plate is formed in the inner top wall of the double-layer circular rotating groove; according to the utility model, the mounting piece is connected with the air cylinder preset at the top of the existing assembly table, so that the circular connecting plate can be ensured to correspond to the position right above a pressure gauge plate which is limited on the existing assembly table in advance, and a pressure gauge shell clamped by the clamping piece is clamped by the clamping piece; under the inst
