A quick compressor connecting rod connecting device

Abstract

The invention discloses a connecting rod connecting device of a rapid compression machine. The rapid compression machine comprises a fuel compression piston connecting rod and a driving piston connecting rod, and the fuel compression piston connecting rod is connected with the driving piston connecting rod through the connecting device. The connecting device comprises a connecting piston and a spline shaft which are connected with each other in a buckling mode and are capable of moving mutually in a connected state. The fuel compression piston connecting rod is movably connected with the driving piston connecting rod through the connecting device, the mounting positions of both the fuel compression piston connecting rod and the driving piston connecting rod are adaptively adjusted during assembly, the requirement for the machining accuracy of the two connecting rods and the requirement for the coaxiality accuracy of the two connecting rods during assembly are lowered, and the production cost is reduced.

Description

【Technical field】 [0001] The invention relates to the fields of fuel ignition, chemical reaction kinetics experiment device, energetic material impact, thermal loading experiment device, engine compression stroke simulation and fuel visualization atomization ignition experiment device, etc., in particular to a fast compressor connecting rod connecting device. 【Background technique】 [0002] The fast compressor structure widely used in the world is a double-link three-piston structure, including two connecting rods, a driving piston, a deceleration piston and a fuel compression piston; among them, the two connecting rods are fixedly connected by a connecting piston, and the driving piston and the fuel are connected. The compression piston is connected to both ends of the two connecting rods, the whole structure is arranged in a straight line, and the movement direction is axial movement. [0003] The fixed connection between the two connecting rods of the traditional fast com...

AI Technical Summary

Problems solved by technology

Since the two connecting rods are fixedly connected by threads, the concentricity of the two connecting rods is prone to deviation after the fixed connection, resulting in the movement speed of the fast compressor failing to meet the experimental requirements, and due to the concentricity of the two connecting rods Different, the cylinder body is easy to cause damage to the connecting rod during the movement, causing a serious problem that the fast compressor cannot work

[0005] In view of the above problems, it is necessary to design a design connecting device to solve many problems caused by two connecting rods connecting two connecting rods due to different coaxiality
