Processing method for holes in multi-lug-plate parts with dense spaces

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...

[0002] In the field of mechanical processing, two methods are usually used for the processing of traditional multi-lug holes: one method mainly relies on setting a drilling template between the two lugs, and by changing the diameter of the guide sleeve in the drilling template To realize the processing of the coaxiality of the hole, its disadvantages: ① It needs to disassemble and assemble the parts many times to replace the guide sleeve in the drill 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 lugs, so chip removal is affected during processing, and it is easy to cause scratches on the surface of the part; another method is to design the drilling template between the lugs as a joint structure, through the joint Activities to expand the installation space and replace the guide sleeve in the drilling template. The disadvantages: ① Due to the gap between the joints, there is also a cumulative error in positioning, which affects the accuracy of the coaxiality. ② The drilling template structure is complex , high manufacturing cost
