Embodiment Construction

[0022] see image 3 with Figure 4 , In the processing technology of the locomotive bogie frame in this embodiment, first draw the horizontal X and vertical Y centerlines on the frame and align them to determine the coordinate positions of the frame in the X and Y directions. Then, to locate on the blank surface of the frame, on the basis of the existing positioning and clamping in the vertical Z (up and down) direction, add positioning tooling and clamping points in the X, Y (left and right) directions (X direction positioning points 3, X Clamping point 4, Y-direction positioning point 5, Y-direction clamping point 6), so as to ensure the stability of the frame during the process of processing a series of surfaces 2. After processing each processing position on a series of surfaces 2, the frame is adjusted. Then use the processed first-series surface 2 for positioning, no need to re-align again, just use the tooling to position on the processed first-series processing surfa...

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

technical field [0001] The invention relates to a process for processing a locomotive bogie frame, and belongs to the technical field of railway locomotive manufacturing. Background technique [0002] The locomotive bogie is the main part of the running part of the locomotive. It is composed of frame, wheel set assembly, axle box, primary suspension, secondary suspension, traction device, motor suspension device, foundation brake, accessory device and other components. The frame is The skeleton of the bogie, which organizes other parts of the bogie together to form the whole of the bogie, is a very critical and important part of the running gear of the locomotive. See figure 1 with figure 2 . In the prior art, the following technological measures are taken to process the frame: [0003] 1) Positioning and clamping of the frame. First hang the marked frame on the workbench of the processing machine tool, make the secondary spring seat plate of the frame face up, put the ...
