Anti-vibration device and method for processing diesel engine frame

Abstract

The disclosure relates to an anti-vibration device and method for processing a diesel engine frame, which includes two pressure plates arranged side by side, and the sides of the two pressure plates facing away from each other are used to compress the plate to be damped. The scissor bracket, the scissor bracket can adjust and fix the distance between the two pressure plates through the deformation of the scissors under the condition that the two pressure plates are parallel. The disclosure can reduce the vibration of the intermediate body and the intermediate plate during the processing of the frame of the diesel engine frame, and improve the processing quality.

Description

Technical field [0001] The present disclosure belongs to the field of diesel machining, and is specifically related to the anti-vibration device and method for the processing of a diesel agent frame. Background technique [0002] The diesel engine main base and rack raw materials are structural parts soldered by steel sheets. The top surface processing drawings of the base requires a planar degree of 0.1 mm / 1000x1000, surface roughness Ra = 3.2; the bottom surface of the rack is 0.05mm / 1000x1000, surface roughness Ra = 3.2; due to large structural characteristics, intermediates or The intermediate plate extension is longer hollow, and the cutter can generate vibration when cutting. If it is not possible to perform effective anti-vibration, the seat, the frame plane and roughness is difficult to meet the drawing requirements during processing. [0003] The inventors have learned that the processing of the anti-vibration method usually uses the screw and nut to support the two ...

AI Technical Summary

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.
