Abstract

The invention discloses a clamp for an air introduction pipe machining and a clamping method, and belongs to the field of machining clamps. The clamp comprises a core shaft and an end surface pressingmechanism, wherein the core shaft is used for being coaxially inserted into an air introduction pipe, and a first shaft shoulder abutting against one end of the air introduction pipe is arranged on the side wall of the core shaft; the end surface pressing mechanism is detachably connected to the end surface of one end of the core shaft, and the end surface pressing mechanism is used for pressingthe end surface of the other end of the air introduction pipe; and the air introduction pipe is arranged on the core shaft in a sleeving mode, then the air introduction pipe can be positioned in the radial direction, the first shaft shoulder can abut against one end of the air introduction pipe, and the end surface pressing mechanism presses the other end of the air introduction pipe, so that axial positioning of the air introduction pipe is realized. According to the clamp, the axial and radial stable clamping of the air introduction pipe can be quickly realized, and the phenomenon that the wall thickness is uneven due to the fact that the air introduction pipe is clamped to deform is avoided, so that the production efficiency of the air introduction pipe is improved, and the rejection rate is reduced.

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...
