Embodiment Construction

[0013] The following is attached with the manual Figure 1-3 The present invention is further described in detail.

[0014] A straight dovetail type tenon and groove wire cutting processing method, 1) using wire cutting to process the tenon and groove, first manufacturing a plurality of bottom plates;

[0015] 2) In order to make the bottom plate in step 1) adaptable to the versatility in the processing of different parts, a plurality of threading holes and a plurality of positioning holes are provided on the bottom plate according to several parts structures;

[0016] 3) The bottom plate is fixedly connected with the parts by bolts through the positioning holes; the bottom plate of the clamped parts is installed on the wire cutting machine, and the side of the bottom plate is used for straightening and alignment; all the tongues and grooves of the clamped parts can be processed at one time; There is no cutting force during processing, which can reduce the deformation of part...

Abstract

The invention discloses a linear cutting machining method for straight swallowtail-type mortises. The linear cutting machining method comprises the steps that (1) mortise machining is conducted by adopting a linear cutting mode, and a plurality of bottom plates are made firstly; (2) in order to make the bottom plates in the step (1) adapt to universality in the machining process of different parts, a plurality of wire threading holes and a plurality of positioning holes are formed in the bottom plates according to the structures of the several parts; and (3) the bottom plates are fixedly connected with the parts by using bolts through the positioning holes, the bottom plates for mounting and clamping the parts are mounted on a linear cutting machine tool, the side faces of the bottom plates are used for straightening and alignment, all the mortises can be machined in the mounted and clamped parts at a time, cutting force does not exist in linear machining, and deformation in part machining can be reduced. The linear cutting machining method is further suitable for being used for removing of the allowance when surface quality requirements are high and reducing of part deformation caused by allowance removing in the machining process.

Description

technical field [0001] The invention is applied to the technical field of straight dovetail tenon and groove processing of fan discs, and is suitable for processing similar structural parts, and is specifically a straight dovetail tenon and groove wire cutting processing method. Background technique [0002] Except for the annular tenon and groove, broaching and milling are generally used in the processing of tenon and groove, and the broaching process has high precision, but the manufacturing cycle of the broach is long and the manufacturing cost is high; the number of milling cutters required for milling is large; broaching and milling The process will cause part processing deformation. The wire cutting method can not only reduce the tool cost, but also reduce the processing deformation. Contents of the invention [0003] The purpose of the invention is to reduce the tool cost for tenon and groove processing and reduce the deformation caused by tenon and groove processi...
