Problems solved by technology

At present, there is no special fixture for parts spraying, but simple positioning of parts, simple structure, strong random operation and extremely inconvenient use. Use heat reflective tape or other suitable materials to protect non-spraying areas on non-spraying surfaces, and the protection ability is poor.

Embodiment Construction

[0017] Referring to the attached drawings, aircraft slide rails such as figure 1 As shown, the end of the slide rail part 1 is the part joint 2, and the part joint 2 is provided with a positioning surface and a connecting hole for assembly. The body of the slide rail part 1 is a polyhedron structure with grooves 4 on three sides, such as figure 2 As shown, when flame spraying, the sprayed surface 3 needs to be exposed, and the part joints 2 and grooves 4 need to be protected. To this end, the present application provides a protective jig, the protective jig is composed of image 3 The fixture base shown and Figure 4 The slide rail protection body shown is composed of the described fixture base body containing a fixture base 5 on which a positioning corner seat 6 of the part joint is fixed. The positioning corner seat is composed of left and right parts, and the positioning corner seat is fixed through a U-shaped connecting hole On the fixture base, the distance between the...

Abstract

The invention discloses a flame spraying protection method for an aircraft slide rail part. A protecting clamp is used and comprises a clamp body and a slide rail protecting body. Before flame spraying, a connector of the slide rail part is fixed on positioning angle seats of a clamp base, the height of each connector protecting plate is adjusted to be appropriate, and accordingly, the part connector is prevented from being sprayed; curved-surface protecting plates are embedded in matched slide rail part cavities respectively and are fixed with a slide rail part body through positioning pins; the clamped slide rail part is subjected to flame spraying, and then the protecting clamp is dismounted.

Description

technical field [0001] The invention belongs to the field of surface protection and surface strengthening, and relates to a flame spraying protection method and a protection fixture for aircraft slide rail parts. Background technique [0002] As a new surface protection and surface strengthening process, flame spraying technology has developed rapidly in the past 20 years and has become a very active branch in the field of metal surface engineering. Using the flame as the heat source, the metal and non-metal materials are heated to a molten state, and a mist flow is formed under the impetus of high-speed airflow, which is sprayed onto the substrate. The sprayed tiny molten particles impinge on the substrate, causing plastic deformation to become a superimposed deposited coating, a process called flame spraying. These shape-changed particles are superimposed to form a coating. Spraying has the prerequisite for the transformation of the stress state of the coating from tensi...
