Abstract

A multi-function positioning clamping method for machining receivers is used for clamping and fixing similarly structured receivers in machining; parts are more convenient to clamp, machining cost is reduced significantly, machining efficiency is improved, machining cycle is shortened, and machining quality is guaranteed. Allowances are removed from the parts by early roughing and finishing, and then the parts meet the design requirement; one face to be machined is used as a clamping fixation reference; the reference mounting edge of each part is positioned and supported through a positioning block, a positioning pin and a support block; the part is then clamped with a press plate and is pressed to a fixture base; a fixture with the part is hoisted to a machine tool bench; a first receiver is machined according the dimensions before the part is separated, and before continual machining, changing different parts to be machined is required only. The method has the advantages that the problem of using a universal fixture to clamp different sizes of receivers whose reference mounting edge is symmetric is solved; machining cycle is shortened; machining efficiency is improved.

Description

A kind of multi-functional method for positioning and clamping of processing casing class part
Technical field
The present invention relates to the Machining Technology field, particularly a kind of multi-functional method for positioning and clamping of processing casing class part.
Background technology
As the important component of aero-engine, the convenient reliability that its clamping is fastening, directly affect precision and the working (machining) efficiency of processing dimension.When engine crankcase class part processing operation, a set of special fixture of the many employings of the part of a size in the past.For some structural similarities, the different engine crankcase class formation part as the location dimension of benchmark particularly, processing is accurately to locate by mounting edge seam and end face, needs to make different special fixtures and realizes.There is limitation in the location clamping mode traditional for this type of part.The prior art that the present invention is the most relevant is that a part processing needs to make a kind of special fixture, to realize the accurate clamping of member, the deficiency of the method is that the member of processing different size needs constantly to manufacture new special fixture, increase manufacturing cost, working (machining) efficiency is slow, affect the process-cycle, and be unfavorable for physical asset management etc.
Summary of the invention
The objective of the invention is to make in the member process clamping more convenient, significantly reduce frock manufacturing expense and processing cost, improve working (machining) efficiency, shorten the process-cycle, guarantee crudy, the spy provides a kind of multi-functional method for positioning and clamping of processing casing class part.
The invention provides a kind of multi-functional method for positioning and clamping of processing casing class part, it is characterized in that: for processing structure, the clamping of similar casing class A of geometric unitA is fixed, and makes the member clamping more convenient, significantly reduce processing cost, improve working (machining) efficiency, shorten the process-cycle, guarantee crudy;
Part roughing premenstruum (premenstrua), fine finishining are removed surplus and are reached designing requirement, one side to be processed, as the clamping fixed reference, first positions support to part benchmark mounting edge 11 use the first locating pieces 5, the second locating piece 7, the 3rd locating piece 8, alignment pin 9 and back-up block 4; Carry out clamping with the first pressing plate 6 and the second pressing plate 10 again, be pressed on clamp base 1; To with the fixture of part, be lifted on platen again; By measuring piece 3 and playing table and carry out centering fixture, compressing fixture; With processing parts after feeler block 2 tool settings;
The initial workpiece casing rear separate component of sizing, do not need again to change fixture, do not need clamper for disassembling, do not need centering fixture again, only needs to change different processing parts, then continues to process.It is pointed out that this multifunction clips clamping method is in the location clamping of whole part and process, fully not limited in adjusting the installation clamping process, there do not is the interference and collision risk yet, can continue to process the part of different size after the part completion of processing.
This multi-functional method for positioning and clamping usually can be for different size structure circle, location before the processing of regular polygon benchmark mounting edge part clamps, the clamping fixed form also can play a role with other fastener means together with the vacuum suction fastening means, this multi-functional method for positioning and clamping efficiently solves structural similarity, the different casing class of size part location clamps a difficult problem, avoided different parts need to process the loaded down with trivial details of multiple special fixture, saved clamping switching time, saved the frock manufacturing expense, improve working (machining) efficiency, eliminated the quality risk caused owing to repeatedly changing fixture.
The described casing class A of geometric unitA similar for processing structure refer to, positioning datum is circle or regular polygon, the casing class A of geometric unitA that size is different.
Advantage of the present invention:
The multi-functional method for positioning and clamping of processing casing class part of the present invention, close part to aero-engine casing, by the mounting edge positioning datum of part, manufactures and designs the general fixture that tightens up of different benchmark mounting edge sizes; Play accurate location clamping action to planting to be processed; The clamping and positioning piece adopted, measurement piece, feeler block and pressing plate etc. can not affect continuity and the accurate security of part processing; For the fixedly clamping structure of different size casing datum level, can selection and the process of process tool do not impacted; Its more significant advantage is the special fixture that does not need to make the various structures size members; Efficiently solve the universal fixture clamping problem of casing class part as the mounting edge symmetrical structure different size part of benchmark; Avoided different part processing will repeatedly again change the loaded down with trivial details of special tooling; Again the error that the centering fixture brings; Make processing and loading clamp fixing more simple and efficient; Significantly reduce manufacturing cost; Shorten the process-cycle; Improve working (machining) efficiency; Successfully realized the processing checking of the casing class part of aero-engine different size has been promoted to the machining manufacture level.Simultaneously, it can be used for reference and be applied in industry and other equipment manufacture and special process field.
