Fast press-fitting device and method for large-diameter annular high-pressure sealing steel wires

Abstract

The invention discloses a fast press-fitting device and method for large-diameter annular high-pressure sealing steel wires, comprising a body, wherein the center of the top of the body is provided with a machine tool connecting taper shank used for being connected with a radial drilling machine spindle, the center of the bottom of the body is provided with a center positioning shaft cooperating with the center of a part for positioning, the two sides of the center of the body are provided with a left rolling wheel mechanism and a right rolling wheel mechanism, rolling wheels are arranged on the left rolling wheel mechanism and the right rolling wheel mechanism, the two rolling wheels are matched with an inner annular groove and an outer annular groove of the part in position, grooves areformed in the bottoms of the rolling wheels, the steel wires are embedded into the grooves, and when the body rotates, the rolling wheels drive the steel wires to be press-fitted in the inner annulargroove and the outer annular groove respectively. The height dimension consistency of the press-fitted sealing steel wires is accurately controlled, and the accurate rolling of the sealing steel wiresin the two annular grooves is completed, so that the production efficiency is high, and the whole device is convenient, simple and fast to operate.

Description

technical field [0001] The invention belongs to the technical field of mechanical tooling, and relates to a fast press-fitting device and method for a large-diameter annular high-pressure sealing steel wire. Background technique [0002] The cylinder head is one of the key parts of the engine. Two ring-shaped sealing structures are formed on the surface of the cylinder head, and the cylinder head and the cylinder block are connected together by 24 studs. The tightly pressed and sealed cylinder head and cylinder block form a closed combustion chamber in the inner cavity of the cylinder liner. Due to the intense heating and corrosion of the high-temperature gas in the combustion chamber, the surface between the cylinder head and the cylinder block must have good sealing performance. Therefore, the press-fitting of the sealing wire on the surface of the cylinder head is very important. The schematic diagram of the design of the annular high-pressure sealing groove is shown in...

AI Technical Summary

Problems solved by technology

[0003] The main technical defects of the above-mentioned technical scheme are: firstly, difficult operation, large human factors, low production efficiency, difficult guarantee of product quality, high replacement rate of sealing steel wire after press-fitting; The height of the sealing wire is inconsistent at 0.2±0.05mm, which affects the high-pressure sealing performance of the cylinder head and the reliability of the engine.
