A Universal Automatic Coaxial Mechanism of Oil Cylinder of CNC Shearing Machine

Abstract

The invention discloses a universal automatic coaxial mechanism of a numerical control plate shearing machine oil cylinder. The universal automatic coaxial mechanism of the numerical control plate shearing machine oil cylinder comprises a plate shearing machine frame body, wherein the plate shearing machine frame body is fixed to an oil cylinder via an abrasion-resistant bearing; the oil cylinder is connected with a driving part synchronous torsion axle; a spherical bearing is arranged at the lower end of a piston rod of the oil cylinder and is fixed by a lower fixing bracket mounted on the plate shearing machine frame body; an upper cutter frame sleeves the piston rod of the oil cylinder; a bracket is fixed on the oil cylinder; a universal cross axle is fixed on the bracket and is also fixed on the plate shearing machine frame body; the spherical surface of the lower end of the oil cylinder is mechanically matched with the universal cross axle. According to the universal automatic coaxial mechanism of the numerical control plate shearing machine oil cylinder, the spherical surface of the lower end of the oil cylinder is mechanically matched with the universal cross axle, so that the abrasion of the shearing counter-acting side force on the oil cylinder can be automatically adjusted, thus the center of the piston rod of the oil cylinder and the center of the inner wall of the oil cylinder are automatically and coaxially adapted to each other; the influence of factors such as the counter-acting side force of the shearing process, the frame welding stress deformation and oil cylinder assembling errors and the like on the oil cylinder can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of a numerical control shearing machine, in particular to a universal automatic coaxial mechanism of an oil cylinder of a numerical control shearing machine. Background technique [0002] The shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. It uses the moving upper blade and the fixed lower blade to apply shearing force to metal sheets of various thicknesses with a reasonable blade gap, so that the sheets are broken and separated according to the required size. The shearing machine is a kind of forging machinery, and its main function is the metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets ...

Problems solved by technology

The oil outlet of the oil cylinder of this structure is directly opened on the side wall of the oil storage tank. When the piston exerts pressure, the oil in the oil storage cylinder will flow out through the oil outlet, but when the piston does not apply pressure, due to the airtightness of the oil cylinder If the effect is not good, air will enter, which will cause oil leakage, which will not only cause waste of raw materials, but also cause wear and tear on the piston rod and the inner wall of the cylinder over time, causing damage
