A nickel-plated protective fixture

Abstract

The present invention relates to the field of clamps, specifically a nickel-plated protection clamp, including a conductive rod, a regulator, a clamping mechanism and a hook mechanism. Two regulators with the same specification are installed on the conductive rod, and one of the The fixed collar in the regulator is fixedly sleeved on the conductive rod near the top of the rod at 15-18cm, and the fixed collar in the other regulator is fixedly sleeved at the conductive rod near the bottom of the rod at 2-3cm. The regulator includes a fixed collar, a square through pipe, a support rod and a first thumb screw. Both side walls of the fixed collar are fixed with horizontally arranged square through pipes, and the two square through pipes are symmetrically distributed. A support rod for sliding connection is inserted in the square through pipe, and a threaded through hole is opened at the center of the outer wall of the square through pipe, and a first thumb screw for threaded connection is inserted in the threaded through hole. The nickel-plated protective clip provided by the invention has the advantages of being able to flexibly adjust the number of workpieces installed and preventing slipping.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a nickel-plated protection clamp. Background technique [0002] The power turbine shaft in the aircraft parts is made of 1Cr17Ni2. When the part is nitriding, the non-nitriding surface is first electroplated with nickel. The existing fixture adopts a bifurcated bracket type mounting structure, and the parts are all horizontal. On the bifurcation, the reason for the poor quality of the nickel layer is mainly because there are major problems in the existing tooling fixtures: when installing and hanging, part of the nickel-plated surface is in contact with the fixture, and the nickel layer on the contact surface cannot meet the process requirements; Flexibly adjust the clamping mechanism according to the number of nickel-plated workpieces. Due to the existence of the above problems, parts are often scrapped due to nitrogen leakage. Therefore, it is necessary to provide a nickel-plated protect...
