摘 要
本文是對泵體零件加工應(yīng)用及加工的工藝性分析，此外還對鉆削泵體上3-M6-7H的螺紋孔以及銑削泵體底面的兩道工序的加工設(shè)計了專用鉆床夾具及專用銑床夾具。
在機床上加工工件時，為了保證加工精度，必須正確安裝工件，使其相對機床切削成形運動和刀具占有正確的位置，這一過程稱為“定位”。為了不因受切削力、慣性力、重力等外力作用而破壞工件已定的正確位置，還必須對其施加一定的夾緊力，這一過程稱為“夾緊”。定位和夾緊的全過程稱為“安裝”。在機床上用來完成工件安裝任務(wù)的重要工藝裝備，就是各類夾具中應(yīng)用最為廣泛的“機床夾具”。
機床夾具的種類很多，但廣泛用于批量生產(chǎn)，專為某工件加工工序服務(wù)的專用夾具，需要各制造廠根據(jù)工件加工工藝自行設(shè)計制造。因此，專用夾具的設(shè)計是一項重要生產(chǎn)準備工作，每一個從事加工工藝的工裝設(shè)計人員，都應(yīng)該掌握有關(guān)夾具設(shè)計的基礎(chǔ)知識。

Abstract
This paper is on the bracket parts processing application and processing technology and analysis, In addition to the stuffing box cover part two process designing special fixture.
Processes the work piece when the engine bed, to guarantee the working accuracy, must install the work piece correctly, causes its relative engine bed cutting builder motion and the cutting tool holds the correct position, this process is called “the localization”. For because of exogenic processes and so on cutting force, force of inertia, gravity is not destroyed the work piece already the correct position which decides, but must exert certain clamping force to it, this process is called “the clamp”. The localization and the clamp entire process is called “the installment”. Uses for on the engine bed to complete the work piece to install the duty the important craft equipment, is in each kind of jig widely applies “the engine bed jig”.
The engine bed jig's type are many, the use scope broadest universal jig, the specification size many have standardized, and has the specialty factory to carry on the production. But widely uses in the volume production, specially unit clamp which serves for some work piece working process, then needs various factories independently to design the manufacture according to the work piece processing craft. Therefore, unit clamp's design is an important production preparatory work, each is engaged in the processing craft the work clothes designers, should grasp the related jig design the elementary knowledge.
