The invention discloses a clamp and a clamping method for processing an air introduction pipe, belonging to the field of mechanical processing clamps. The fixture includes a mandrel and an end face pressing mechanism. The mandrel is used to be coaxially inserted into the air introduction pipe. The mechanism is detachably connected to the end surface of one end of the mandrel, and the end surface pressing mechanism is used to compress the end surface of the other end of the air introduction pipe, and the air introduction pipe is sleeved on the mandrel, and the air introduction pipe can be radially Positioning, the first shoulder can be offset against one end of the air introduction pipe, and the end surface pressing mechanism presses the other end of the air introduction pipe, thereby realizing the axial positioning of the air introduction pipe. The clamp can quickly realize the stable axial and radial clamping of the air introduction pipe, and prevent the uneven wall thickness of the air introduction pipe due to clamping deformation, thereby improving the production efficiency of the air introduction pipe and reducing the cost of the air introduction pipe. Rejection rate.
Description
technical field [0001] The invention belongs to the field of machining fixtures, in particular to a fixture and a clamping method for machining an air introduction pipe. Background technique [0002] Fixtures are commonly used devices in the machining process of mechanical parts. [0003] The air inlet pipe is a common air inlet pipe in gas turbine products. When processing the air inlet pipe, it is necessary to clamp the air inlet pipe with a clamp first, and then process the air inlet pipe to finally obtain the air inlet pipe that meets the process size requirements. Introduce tube. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Due to the thin long wall of the air inlet pipe shaft, the air inlet pipe is prone to deformation during the actual clamping process, which affects the processing. Contents of the invention [0006] Embodiments of the present invention pro...
