Embodiment 1

[0031] The single-dimensional wedge-shaped workpiece processed in this embodiment is a component in a locking mechanism, with a length of 1500 mm and a width of 400 mm. As the inclined plane of the working surface, the inclination is 15 degrees, and the processing smoothness of the reference plane and the inclined plane is ▽ 0.8. The machining process of this single-degree surface wedge-shaped workpiece is as follows:

[0032] (1) The reference plane of the milling workpiece;

[0033] (2) Taking the datum plane after milling as the machining datum for machining the inclined plane of the workpiece, milling and grinding the inclined plane of the workpiece;

[0034] (3) 5 process bosses with a width of 100 mm, a lower end surface as a plane, and an upper end surface as an inclined plane consistent with the inclination of the inclined plane of the workpiece are bonded equidistantly on the inclined plane of the workpiece with an epoxy metal adhesive;

[0035] (4) Take the process...

Abstract

The invention discloses a machining process method of a large-size single degree face wedge-shaped workpiece. The method comprises the process steps that (1) a reference plane of a workpiece is machined by milling; (2) the reference plane obtained after milling is used as the machining reference for machining a workpiece oblique plane, and the oblique plane of the workpiece is machined by milling and grinding; (3) a mounting process boss for workpiece reference plane grinding adheres to the workpiece oblique plane through metal adhering agents; (4) a process boss on the oblique plane is used as the mounting reference of machining reference plane by grinding, and the reference plane is machined by grinding; and (5) after the reference plane is machined by grinding, the process boss is taken off from the workpiece oblique plane, the metal adhering agents on the workpiece oblique plane are removed, and single-face wedge-shaped workpiece machining is completed. Compared with a machining method in the prior art, the process of machining method is simplified, machining efficiency is improved, and the machining accuracy of the workpiece is improved.

Description

technical field [0001] The invention relates to a machining method for an asymmetrical workpiece, in particular to a machining process for a wedge-shaped workpiece with one side being a reference plane and the other side being a surface with a certain slope. Background technique [0002] The inclined block mechanism, locking mechanism, and clamping mechanism in the mechanical field all use wedge-shaped workpieces. There are two types of wedge-shaped workpieces, one is an inclined plane with a certain inclination on both sides, that is, a full wedge-shaped workpiece; the other is an inclined plane with a certain inclination on one side, that is, a single-degree surface wedge-shaped workpiece. In the inclined block mechanism, locking mechanism, and clamping mechanism, more single-dimensional wedge-shaped workpieces are used. The wedge-shaped workpiece with single-degree surface usually takes its inclined plane as the working surface and the plane as the reference plane. The ...
