Support platform for assembly and disassembly of diesel engine crankshaft shock absorber

Abstract

The invention discloses a support platform for assembly and disassembly of a crankshaft shock absorber of a diesel engine, comprising an axial V-shaped groove for supporting the shock absorber, a horizontal moving platform and a hydraulic lifting device located below the horizontal moving platform, the axial V A first slide block is extended below the groove, and a first chute cooperating with the first slide block is provided on the horizontal moving platform. The support platform for assembly and disassembly of the diesel crankshaft shock absorber of the present invention has the advantages of simple structure, convenient operation, high installation efficiency, good safety, etc., and uses the support platform to support and fix the shock absorber, which enhances the balance of the shock absorber installation process It avoids the hoisting of the shock absorber; the lateral movement of the axial V-shaped groove and the lifting mechanism can realize the automatic centering of the inner hole of the shock absorber and the axis of the crankshaft up and down, and quickly complete the coaxiality of the inner hole of the shock absorber and the crankshaft Cooperate.

Description

technical field [0001] The invention relates to a support platform for assembly and disassembly of diesel engine crankshaft shock absorbers, belonging to the field of support platforms for assembly and disassembly of large marine diesel engine crankshaft shock absorbers. Background technique [0002] Installing a shock absorber at the front end of the crankshaft is one of the most effective measures to reduce the vibration of the crankshaft. Commonly used diesel engine shock absorbers include low-speed silicone oil shock absorbers, medium-high spring shock absorbers, and high-speed diaphragm shock absorbers. When the diesel engine is working, the shock absorber can absorb a large amount of energy of the torsional vibration of the crankshaft system, thereby slowing down the torsional vibration of the crankshaft, and usually adopts a conical interference fit connection. The stability of the assembly and disassembly process of the shock absorber is conducive to improving the as...

AI Technical Summary

Problems solved by technology

However, the traditional manual crankshaft shock absorber installation method is difficult to achieve accurate positioning of the pin hole, and positioning tooling is required for secondary positioning of the pin hole. When the error is large, the shock absorber needs to be manually rotated. The operation process is complicated and the efficiency It is not high, especially the crankshaft and shock absorber connected by conical interference fit, which is easy to cause scratches on the inner hole of the crankshaft and shock absorber. A workbench with adjustable spatial position is urgently needed
