Abstract

The invention provides a processing method for holes in multi-lug-plate parts with dense spaces. The processing method comprises the following steps of: firstly, mounting a drilling template reaming guide sleeve on a drilling template; secondly, fixing the parts on a drilling jig; thirdly, mounting a drilling template front guide sleeve and a drilling template rear guide sleeve on the drilling template; fourthly, drilling and retaining machining allowance; fifthly, reaming; and sixthly, finishing the processing of the holes in the multi-lug-plate parts. According to the processing method, the production efficiency is increased, the production cost is reduced and the coaxiality of the holes is effectively ensured.

Description

technical field

[0001] The invention relates to a processing method of a part hole in the field of mechanical processing, in particular to a processing method of a hole in a multi-tab type part with a dense spacing. Background technique

[0002] In the field of machining, two methods are usually used for the processing of holes in the traditional multi-tabs: one method is to mainly rely on setting a drill template between the two ears, and change the diameter of the guide sleeve in the drill template to The disadvantages of realizing the coaxiality of the holes are: ① It is necessary to disassemble and assemble the parts several times to replace the guide sleeve in the drilling template, which is inefficient; ② There is a cumulative positioning error; ③ Due to the short distance between the lugs , the drilling template occupies the processing space between the ears, so it affects the chip removal during processing, which is easy to cause scratches on the surface of the parts...
