Problems solved by technology

[0002] like figure 1 As shown, this type of part has double lugs with deep and narrow grooves, and the inner shape is a curved surface. In the past processing of this structure, the thickness of the lugs or the width of the grooves are often out of tolerance, and the corners of the inner shape of this part are rough machined The margin is large, it is easy to produce the phenomenon of knife chatter, and the phenomenon of folding knife and milling damage to parts is inevitable

Embodiment Construction

[0026] A method for processing joints with complex structures of deep and narrow grooves, characterized by comprising the following steps:

[0027] 1) In the design, the joint web is extended, and a positioning hole is set on the extended web, and the hole is used as the origin of the process for processing, and each processing process is based on the origin of the process, which reduces the difficulty of clamping and makes The tooling is simplified, the processing process is clear, and the processing origin is unified during the processing of each surface, which reduces the impact of multiple positioning on the quality of the parts;

[0028] 2) Processing of parts web:

[0029] 2.1) Roughly machine the shape and inner shape of the front of the part;

[0030] 2.2) The part is turned over, and the internal shape of the reverse side of the part is initially processed;

[0031] 2.2) The part is turned over, and the inner shape and shape of the front are finished;

[0032] 2.3)...

Abstract

The invention relates to a method for machining a joint with a deep and narrow groove complicated structure, and the method is characterized by comprising the following steps of: 1) extending a joint web plate during design, forming a positioning hole on the extended web plate, and machining by taking the positioning hole as a process original point; 2) machining a part web plate; 3) carrying out rough and finish milling on lug slots and machining lug slot notches; and 4) machining an internal camber surface by adopting profile segmentation, carrying out half-finish machining by layers by virtue of a vertical milling cutter with the length of 45mm, and carrying out non-layered finish machining by virtue of a vertical milling cutter with the edge length of 90mm. The method can be used for not only effectively solving the problem of poor thickness of lugs, and a more reasonable method is provided for machining the rotating angles of the part, thus improving the integral machining precision of the part and increasing the production efficiency.

Description

technical field [0001] The invention relates to a processing method for joints with complex structures of deep and narrow grooves, which is used for processing joint parts with complex structures of deep and narrow grooves. Background technique [0002] Such as figure 1 As shown, this type of part has double lugs with deep and narrow grooves, and the inner shape is a curved surface. In the past processing of this structure, the thickness of the lugs or the width of the grooves are often out of tolerance, and the corners of the inner shape of this part are rough machined The margin is large, and it is easy to produce the phenomenon of chattering knife, and the phenomenon of folding knife and milling damage to parts is inevitable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a processing method for joints with complex structures of deep and narrow grooves. The machining precision of the parts is high, and the ...
