Bore testpieces inner wall damage restoration simulated testing apparatus

Abstract

The invention discloses a bore testpieces inner wall damage restoration simulated testing apparatus. The apparatus comprises a tool clamp movable plate, the tool clamp movable plate is used for fixinga test member, four guiding shaft apertures are arranged at four angles of the tool clamp movable plate, one end of a guiding shaft is fixed at a tool upper plate, the other end of the guiding shaftpasses through the guiding shaft apertures and is fixed at the tool base plate, ballscrews are arranged at the middle of the tool upper plate and the tool base plate, a ballscrew is connected with a first servo motor, the ballscrew comprises a nut, the nut is fixed at the tool clamp movable plate, a restoration tool connection rack is arranged at the tool upper plate, the restoration tool connection rack is connected with a restoration tool, and a rotary table is arranged in the tool clamp movable plate. The apparatus has the advantages of accurate simulation, simple structure, convenient operation, and low cost, and can realize the observation tests for tissue performance of a bore component inner wall damage recovered layer and optimization of a restoration technology.

Description

technical field [0001] The invention belongs to the technical field of equipment maintenance, and relates to a simulation test device for preparing thermal spraying, surfacing and cladding repair layers on the surface of an inner hole test piece. Background technique [0002] Diesel engine body, bearing seat, engine cylinder liner and other mechanical equipment inner hole parts have to bear the repeated action of load and environmental factors during the service period, and various damages such as corrosion, wear and scratches will gradually appear on the inner wall. When it is damaged to the extent that it does not meet the requirements for use, it is usually repaired by surface engineering techniques such as spraying, surfacing, brush plating or laser cladding. For example, the rotary plasma (RotaPlasma) spraying technology developed by the Swiss Sulzer-Metco company can prepare metal, ceramic and composite material coatings on the inner wall of the aluminum alloy cylinder...

AI Technical Summary

Problems solved by technology

Generally speaking, the current damage repair technology for inner hole test pieces mainly uses plasma flame flow, electric arc, and flame as heat sources, and uses compressed air as atomization acceleration air flow thermal spraying technology or surfacing welding technology, which is affected by many factors such as particle acceleration distance. impact, the repair process is complicated, the cost is high, and it is not easy to popularize and apply
