Embodiment Construction

[0016] The present invention will be further described below according to the embodiments provided by the accompanying drawings.

[0017] The method for processing the oblique hole of the channel steel part includes three steps: step 1, processing preparation, step 2, parameter setting, and step 3, processing implementation.

[0018] Processing preparation stage: CNC milling machine XKA5032A is selected as the processing equipment for milling inclined holes in channel steel. The workpiece is clamped horizontally, and the T-shaped milling cutter is spared. The axis of the milling cutter is perpendicular to the surface of the inclined hole. The axis of the milling cutter and the axis of the inclined hole do not have to be parallel.

[0019] Parameter setting stage:

[0020] Extract the line frame of the inclined hole: use CAD software to draw the three-dimensional solid map of the inclined hole of the channel steel, extract the line frame 1 of the opening and the line frame 6 of...

Abstract

The invention relates to a method for processing inclined holes of channel steel parts. Including processing preparation and processing implementation steps. When preparing for processing, select a CNC milling machine, clamp the workpiece horizontally, and reserve the T-shaped milling cutter. The axis of the milling cutter is perpendicular to the surface of the channel steel. Generate the left ruled surface (11) using the left orifice and hole bottom line frame of the offset right orifice and hole bottom line frame to generate the right ruled surface (12) to complete the corresponding programming; when processing, follow the three-dimensional solid diagram , processing wireframe, rough milling allowance and preset programs, use the bottom tooth (19) of the T-shaped milling cutter to process the left ruled surface (11) in layers, and use the upper tooth (20) of the T-shaped milling cutter to process the right straight surface in layers textured surface (12). The invention has the advantages of simple processing process, improved processing efficiency, reduced labor intensity, safe and reliable operation, unrestricted workpiece size and obvious advantages of numerical control processing.

Description

technical field [0001] The invention relates to a method for processing inclined holes of channel steel parts in the field of mechanical processing. Background technique [0002] In the prior art, the oblique hole machining of channel steel parts is carried out by means of a boring machine, which includes workpiece clamping, initial boring and multiple borings. When the workpiece is clamped, it is necessary to tilt the rotation angle of the channel steel parts and install them on the workbench so that the axis of the inclined hole is parallel to the axis of the spindle; The axis of the hole coincides, and the keyway milling cutter moves along the axis of the spindle to countersink the bottom hole; when boring again, after the initial boring, replace the boring tool and adjust the size of the boring tool for processing; when boring successively, after the previous boring , replace the boring tool, adjust the size of the boring tool, and process the boring successively until ...
