Abstract

The invention provides a technology for machining a locomotive bogie frame. The technology comprises the steps that a horizontal X center line and a longitudinal Y center line are marked on the frame, centering is carried out, and the coordinate positions in the X direction and the Y direction of the frame are determined; the blank face of the frame is used for positioning, and positioning and clamping are conducted in the X direction, the Y direction and the Z direction; all machining parts on a first coordinate face are machined; the frame is turned; the machined first coordinate face is used for positioning, and positioning and clamping are conducted in the X direction, the Y direction and the Z direction; all machining parts in a second coordinate face are machined. According to the technology, operation is simple and convenient, safety and practicability are achieved, and the machining quality and the production efficiency of the frame are improved.

Description

Locomotive bogie frame processing technology
Technical field
The present invention relates to a kind of locomotive bogie frame processing technology, belong to railway locomotive manufacturing technology field.
Background technology
Engine truck is the main element of locomotive running gear, by framework, wheel, the parts such as assembling, axle box, single stage suspension, secondary suspension, draw-gear, suspension device of motor, foundation brake, accessories apparatus are formed, framework is wherein the skeleton of bogie, it has formed other component organization of bogie the entirety of bogie together, be vitals very crucial in locomotive running gear, see Fig. 1 and Fig. 2.In the prior art, take following technological measure processing framework:
1) positioning and clamping of framework.First the framework that pulls line is hung onto on the workbench of machining tool, the secondary spring seat board of framework is faced up, the below (primary spring face) of framework is put into parallels and is adjusted holder.Press the contour processing line on curb girder both sides, find the horizontal level of framework; Press horizontal, the longitudinal centre line of framework, determine the coordinate position of framework X, Y-direction, then with pressing plate, clamp framework (above-below direction clamping), the location that completes framework clamps work;
2) processing two is each working position of side.Mainly comprise processing and the work that drills and reams at the positions such as secondary spring seat surface, locating piece, shock absorber bearing plane;
3) processing one is each working position of side.Processing one is that face need turn over framework, and the primary spring of framework is faced up, and after turning over, needs again centering to position clamping, and location clamping process is with operation 1).Processing mainly comprises processing and the work that drills and reams at the positions such as primary spring seat surface, axle box stopping seat, Brake Block, motor hanger, traction key seat, draw-bar seat internal orifice end face.
There is following problem in above-mentioned processing technology:
1. only on above-below direction, framework is positioned and clamped, lathe is when carrying out horizontal and vertical cutting, and the cutting force of this both direction is that the frictional force of the horizontal direction that produces of the clamping force by framework above-below direction is born completely.When the bite of lathe is little, when cutting force is less than the frictional force that framework clamps up and down, framework is stable, and machining accuracy is high; When bite strengthens, when cutting force is greater than the frictional force that framework clamps up and down, framework just may produce displacement, affects accurate to dimension.
2. first by blank, locating to process two of framework is face and locating piece, and then two is that as the positioning datum of Z direction, to process one of framework be face for face and locating piece with what process.When processing one is face, owing to there is no the location of X and Y-direction, can only lean on the line center line of framework upper and lower surface to carry out centering twice.If the center line of top and bottom not to the heart, causes one to be that face and Er Ximian center do not overlap, just there will be serious mismachining tolerance, also can directly have influence on the assembling quality of framework simultaneously.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of locomotive bogie frame processing technology is provided.
The object of the present invention is achieved like this: a kind of locomotive bogie frame processing technology, is characterized in that taking the following step:
(1) on framework, draw horizontal X, longitudinal Y center line centering, determine the coordinate position of framework X, Y-direction;
(2) with the black skin location of framework, in X, Y, Z direction, location clamps;
(3) processing one is each working position on face;
(4) framework is adjusted individual;
(5) with manufactured one, be face location, in X, Y, Z direction, location clamps;
(6) processing two is each working position on face.
The solution of the present invention, by to the mach technique adjustment of framework, by what first process framework, two be face, changing into and first processing one of framework is face, with one after processing, be that machined surface is face as two of positioning datum processing framework again, having solved one is that face does not overlap with Er Ximian center and guarantees the consistent problem of center line of framework top and bottom; By the mach frock of framework is improved, increase positioning tool and the clamping point of X, Y-direction, guarantee the stability of workpiece work in-process, the crudy that has solved framework is unstable, affects machining accuracy problem.The solution of the present invention, easy and simple to handle, safe and practical, improved machining quality and the production efficiency of framework.
Accompanying drawing explanation
Fig. 1 is locomotive bogie frame schematic diagram.
Fig. 2 is the top view of Fig. 1.
Fig. 3 and Fig. 4 are the locomotive bogie frame processing location schematic diagram of the embodiment of the present invention.
In figure, be labeled as: 1-bis-is machined surface, 2-mono-is machined surface, and 3-X is to anchor point, and 4-X is to clamping point, and 5-Y is to anchor point, and 6-Y is to clamping point, and 7-Z is to anchor point, and 8-Z is to clamping point.
The specific embodiment
Referring to Fig. 3 and Fig. 4, the locomotive bogie frame processing technology of the present embodiment is first being drawn horizontal X, longitudinal Y center line centering on framework, determines the coordinate position of framework X, Y-direction.Then, with the black skin location of framework, upper and lower at vertical Z() on the basis that clamps, the existing location of direction, increase X, Y(left and right) positioning tool and the clamping point (X is to anchor point 3, X to clamping point 4, Y-direction anchor point 5, Y-direction clamping point 6) of direction, with this, guarantee that framework is the stability in face 2 processes in processing one.Processing one is after each working position on face 2, and framework is adjusted.With manufactured one, be that face 2 is located again, do not need to carry out secondary centering again, just by frock, coming to manufactured one is to position on machined surface 2, with this, solving one is that face 2 and two is the problem that the center of face 1 does not overlap, the center line of guaranteeing framework top and bottom is consistent, and in X, Y, Z direction, location clamps.Processing two is the each working position on face 1.
