Adjustable clamp for mounting nickel-based single-crystal high-temperature alloy wafer sample

Abstract

The invention discloses an adjustable clamp for mounting a nickel-based single-crystal high-temperature alloy wafer sample. The adjustable clamp comprises a clamp control end, a flange plate, a connecting nut and a clamp fixing end, the flange plate is in threaded connection with the clamp control end and is used for fixing the clamp at the opening position of the experiment cabin section; the clamp control end comprises an angle adjusting knob, an angle adjusting handle and a height adjusting handle which are coaxially screwed from top to bottom in sequence through threads, the clamp fixing end comprises a base plate and a cover plate, the top of the base plate is connected with the bottom of the angle adjusting handle in an embedded mode, and the base plate is used for containing a nickel-based single-crystal high-temperature alloy wafer sample; the cover plate covers the base plate and is used for fixing a sample, and a hollow hole matched with the sample is formed in the cover plate; the connecting nut is in threaded connection with the bottom of a stand column of the angle adjusting handle, one side of the bottom of the connecting nut is connected with a bolt hole in the top of the cover plate through a pin shaft, and installation of the nickel-based single-crystal high-temperature alloy wafer sample and adjustment of the position and the angle of the sample can be achieved.

Description

technical field [0001] The invention belongs to the technical field of high-temperature deposition experiments of micron particles, in particular to an adjustable clamp used for mounting nickel-based single crystal superalloy wafer samples. Background technique [0002] Nickel-based single crystal superalloys are mainly used in the manufacture of aero-engines and hot-end turbine blades of gas turbines, and their temperature bearing capacity is a key technical indicator to improve engine performance, efficiency and reliability. The aero-engine is the heart of the aircraft. A large number of its components work in a very harsh environment, not only under the workload of high temperature, high pressure and high speed, but also in the harsh environment with a large number of fine particles of sand and dust, and the turbine blades are One of the most representative core components that bear the above-mentioned high loads. In order to meet the pursuit of high thrust-to-weight rat...
