A clamping tool for drilling and reaming of thin-walled parts

Abstract

The invention relates to a clamping tool for drilling and reaming thin-wall parts. The clamping tool for drilling and reaming the thin-wall parts comprises a supporting table, wherein a positioning hole is formed in the supporting table, the axis of the positioning hole is defined to be in the up-down direction, a positioning inner wall surface which is used for accommodating a plurality of the thin-wall parts stacked up and down and is circumferentially in location fit with the thin-wall parts is arranged in the positioning hole, the supporting table is further provided with a limiting structure which is arranged on the lower part of the thin-wall parts at the lowest layer in a blocking mode, and a receding space which of a receding drill bit is arranged at the position, located on the lower part of the limiting structure, of an accommodating hole. The clamping tool further comprises a pressing structure fixed on a supporting seat, wherein the pressing structure is provided with a pressing end extending from top to bottom into the positioning hole and pressing the thin-wall parts on the limiting structure, and the pressing structure is provided with a receding channel for the receding drill bit. The whole positioning and clamping of the thin-wall parts is realized, and the structure is relatively simple.

Description

technical field [0001] The invention relates to a clamping tool for drilling and reaming thin-walled parts. Background technique [0002] Thin-walled parts are mainly sealed connectors installed in pneumatic valves, engine oil tanks, etc., and are used between the supporting surface of bolts, screws or nuts and the connected parts to protect the surface of the connected parts and seal the interface to prevent It is a tight connection for air leakage, oil leakage, fastener loosening prevention or other special purposes. There are many internal applications of the engine, and it has a wide range of applications in the fields of aviation, aerospace, and defense. [0003] The structure of thin-walled parts such as figure 1 As shown, the thickness of the thin-walled part 7 is not greater than 0.1mm, the structure is square, and has a central hole 71 and an eccentric hole 72, and the thickness of the thin-walled part is not greater than 0.1mm, and there are strict requirements o...
