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

Example Embodiment

[0036] Example 1

[0037] like Figure 1-Figure 2 As shown, an anti-vibration device for machining a frame of a diesel engine base is provided, which includes two pressure plates 6 arranged side by side, the sides of the two pressure plates 6 facing away from each other are used to press the plate 1801 to be damped, and the two pressure plates 6 A scissor bracket is connected between them, and the scissor bracket can adjust and fix the distance between the two pressure plates 6 through the deformation of the scissors under the condition of ensuring that the two pressure plates 6 are parallel.

[0038] In this implementation, in order to avoid the surface damage of the plate to be damped caused by the rigid contact between the surface of the pressing plate and the plate to be damped, and to avoid excessive local pressure caused by poor contact between the pressing plate and the plate to be damped In large cases, a rubber pad is covered on the outer side of the pressure plate (...

Example Embodiment

[0049] Example 2

[0050] The present embodiment provides an anti-vibration method for machining a frame of a diesel engine base, which utilizes the above-mentioned anti-vibration device for machining a frame of a diesel engine base, including the following steps:

[0051] Before the damping plate 1801 is processed, adjust the distance between the two pressing plates 6 to a minimum state;

[0052] Place the two pressure plates 6 in the cavity between the two plates to be damped;

[0053] The distance between the two pressure plates 6 is increased by the deformation of the scissor bracket, so that the two pressure plates 6 are respectively pressed against the surfaces of the plates to be damped on both sides.

[0054] Further, when the plates 1801 to be damped are arranged in a row in the frame 18 of the diesel engine base, the inner cavity between the adjacent plates is respectively provided with one of the described anti-vibration devices for machining the frame of the diese...

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...
