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 machining inclined holes of channel steel parts. The method comprises the steps of machining preparation and machining implementation. During machining preparation, a numerical control milling machine is selected, a workpiece is horizontally clamped and a T-shaped milling cutter is used for standby, the axis of the milling cutter is perpendicular to the surface of channel steel, a three-dimensional entity graph is drawn, a machining wireframe is extracted, and the minimum outline rough milling allowance is set; a left straight line curved surface (11) is generated by using a biased left orifice and a hole bottom wireframe, and a right straight line curved surface (12) is generated by using the biased right orifice and the hole bottom wireframe to complete corresponding programming; and when machining is implemented, according to the three-dimensional entity graph, the machining wireframe, the rough milling allowance and a preset program, the left straight line curved surface (11) is machined by utilizing bottom teeth (19) of the T-shaped milling cutter in a layered manner, and the right straight line curved surface (12) is machined by utilizing upper teeth (20) of the T-shaped milling cutter in a layered manner. The method has the advantages that the machining process is simple, the machining efficiency is improved, the labor intensity is reduced, operation is safe and reliable, the workpiece size is not limited, and numerical control machining advantages are obvious.

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 ...
