Embodiment Construction

[0023] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Apparently, the described embodiment is only a part of the examples of the present invention, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] like Figure 1-2 As shown, a kind of method of processing vertical pin hole on the workpiece conical surface of the present embodiment, for example, can be the installation and positioning of the cone barrel of the impact type unit and the mechanical drilling and reaming of the positioning pin hole. The pin design size is a conical pin of φ30x190mm, The taper pin slope is 1:50, and the drilling method includes the following steps:

[0025] (1) According to the shape o...

Abstract

The invention relates to a method for processing vertical pin holes in workpiece taper faces. The method includes the following steps: (1) designing a second workpiece matching with the taper face of a workpiece according to the shape of the taper face of the workpiece, wherein the second workpiece comprises a horizontal surface and a surface matching with the taper face of the workpiece; (2) welding the workpiece with the second workpiece; (3) aligning a drill bit with the central portion of the horizontal surface of the second workpiece to drill downwards vertically till reaching the needed depth of the pin hole; (4) using a cutting tool to cut open the workpiece with the taper face and the second workpiece; (5) grinding the workpiece with the taper face to smooth. The method solves the problem that direct processing cannot be carried out without work aids; combination is facilitated, operation is simple, performance is high, timesaving and laborsaving effect is achieved, and quality and tolerance requirements of the processed pin hole are assured; cutting precision is improved, harm to workpieces is small, and the method is an efficient taper-face workpiece perforating method.

Description

technical field [0001] The invention relates to a method for processing holes, in particular to a method for processing vertical pin holes on a tapered surface of a workpiece, which belongs to the field of punching and drilling. Background technique [0002] At present, in the process of mechanical installation, positioning between workpieces is required, and sometimes tapered workpieces are processed. Without the aid of auxiliary workpiece positioning, it is impossible to directly process on tapered workpieces. It is economical and beneficial to process with the workpiece, and the cost is zero. Although this method is simple and clear, at the same time, the hinge pin hole is a very laborious task. The manufacturer's factory equipment generally does not have positioning pin holes. Self-processing and drilling, reaming the pin holes, and finally positioning the workpiece are time-consuming and labor-intensive. At present, when cutting the cone surface, it is operated with a g...
