Anti-vibration device and method for machining diesel engine base rack

Abstract

The invention relates to an anti-vibration device and method for machining a diesel engine base rack. The anti-vibration device comprises two pressing plates arranged side by side, wherein the opposite side faces of the two pressing plates are used for pressing a plate to be damped; a shear fork bracket is connected between the two pressing plates; and the shear fork bracket can adjust and fix thedistance between the two pressing plates through shear fork deformation under the condition that it is guaranteed that the two pressing plates are parallel. According to the anti-vibration device, vibration of a middle body and a middle plate can be reduced during machining of the diesel engine base rack, so that the machining quality is improved.

Description

technical field [0001] The disclosure belongs to the technical field of diesel engine processing, and in particular relates to an anti-vibration device and method for processing a diesel engine frame. Background technique [0002] The base and frame of the main engine of the diesel engine are structural parts assembled and welded by steel plates. The plane processing drawing on the top of the machine base requires a flatness of 0.1mm / 1000x1000, surface roughness Ra=3.2; the flatness of the bottom surface of the frame requires 0.05mm / 1000x1000, surface roughness Ra=3.2; due to the structural characteristics of large parts, intermediate or The middle plate protrudes longer and each gear is hollow, and the cutter head will vibrate during cutting. If it cannot be effectively anti-vibration during processing, the flatness and roughness of the machine base and frame cannot meet the requirements of the drawing. [0003] The inventor has learned that the anti-vibration method of pr...

Problems solved by technology

The plane processing drawing of the top of the machine base requires a flatness of 0.1mm / 1000x1000 and a surface roughness of Ra=3.2; the flatness of the bottom surface of the frame requires a flatness of 0.05mm / 1000x1000 and a surface roughness of Ra=3.2; due to the structural characteristics of large parts, intermediate or The middle plate protrudes longer and each gear is hollow, and the cutter head will vibrate during cutting. If it cannot effectively prevent vibration during processing, the flatness and roughness of the machine base and frame cannot meet the requirements of the drawing.

[0003] The inventor has learned that the anti-vibration method of processing usually uses a screw and a nut to support two adjacent intermediate bodies or intermediate plates. After the support, the cutting vibration of the cutter head will be improved. However, since the screw is supported by two points of force, the point contact The contact surface of the anti-vibration tooling is small, the anti-vibration effect is poor and not fixed, and it is difficult to ensure the roughness of the processed surface

[0004] Secondly, for the point support of ordinary screw support, the pressure is greatly affected by the support force, which is prone to support deformation

The installation position and installation method of the anti-vibration tooling have a relatively important influence on the anti-vibration effect of the workpiece, but it is difficult to constrain it with ordinary screw supports

[0005] At the same time, when using ordinary screw support, the staff usually turn the nut and screw by hand, and judge whether the support is in place completely by experience. There may be insufficient support or deformation of the intermediate body and intermediate plate to be damped.
