Machining method for through hole in angular combination device

Abstract

The invention relates to a machining process for a through hole in an angular combination device, in particular to a machining method for a through hole in an angular combination device. A machining clamp for the through hole in the angular combination device is adopted, and machining of the through hole in the angular combination device is achieved on a high-speed milling machine; a first combination part is positioned and clamped through an axial pressing bolt, an end face positioning block, a lateral pressing bolt and a lateral positioning block, and a through hole in the combination part is machined; and an axial positioning bolt is loosened, a second combination part is in inserted, angular combination is achieved, the pressing bolt is screwed, a tool is switched, a high-speed micro cutting milling method is adopted, and a through hole in the second combination part is machined. By means of the method, matching errors produced by through hole separated machining are well avoided,influences produced by different material cutting on a tool are avoided, the cutting movement phenomenon is reduced fundamentally, and the through hole machining quality is effectively improved.

Description

technical field [0001] The invention relates to a processing technology for a through hole of an angular combination device, in particular to a processing method for a through hole of an angular combination device. Background technique [0002] There are two traditional processing methods for the through-holes of assemblies with angular combination requirements. The first method is to directly process the through-holes in two single parts according to the final matching angular requirements of the parts, and then process them according to the angular requirements. Assembled together, due to single-piece processing and the accumulation of multiple tolerances in component assembly, the final penetration effect is average and the accuracy is relatively low. The second method is to position and process the through hole in the component at one time. Because this method needs to cut two different parts materials at the same time, it puts forward high requirements on the cutting pe...

[0002] There are two traditional processing methods for the through-holes of assemblies with angular combination requirements. The first method is to directly process the through-holes in two single pieces according to the final matching angular requirements of the parts, and then press the angular requirements. Assembled together, due to single-piece processing and the accumulation of multiple tolerances in component assembly, the final penetration effect is average and the accuracy is relatively low

The second method is to position and process the through hole in the component at one time. Because this method needs to cut two different parts materials at the same time, it puts forward high requirements on the cutting performance of the tool. In addition, the huge cutting force generated by the cutting tool will cause The slight movement of the contact surface of the two parts will affect the processing quality of the through hole
