(一)Combmtvin drilling machine is a large combination machine it adept a dispose form. The form has a fixed fitture’s single working location combination.
This kind of combination machine fitture and working bench are all fixed. Powen-sliding plat makes advam cry mourent. The power box on the power sliding plat from made scatting movement.This comgination and agle in instuit and is comvenient in desxging making and operating .Acording to precision demerd it adopt a datum place fixed in side .It is lined light with après lump on the other lylinder side against the datum palne .Itcan read working prelistion indemard a wording to the datum plane. Bacause of it is high working precision in side besides it has a round hole in high precision in side. It has a threaceling hole on the ohassion.
It can make full use of the strulture charactlst of the work piece. To design two short round cancel in the round hole in the side. To limit three degrees .To design acutside cancel on the bassface the battom. To limit one free degree. To limit three free degree one the deofimtine datum plane.It definet up a ccnrately and it’s fixture power is depene.
(二)To desing the combination machine body-therr draning and one carcl that is ① the working orther draning of the working spares . it’s the major basis of the combination maching body. It’s a important paper in making using excmining and rensing maching .②To draw working schematw. Drawing it’s for design a cutting tool. Assist tool afixture a multiple axle box hydravlive,pressure and a deetric capacity derise and important first hand date of the natirrad. Pants chovced and it’s a rewse machine kinf tool and the mgor basis for the test run.③ To draw the relation dimension drawing the relation dimension drawing is to impress the matual .assembly nelation and the motin redation of the each form spanes of the machine.in order to enamine the relative .Pustion of all the machine spares and if the dimersion nelational .Spares is fix ,in the disigerents of dere loping the main axle box fixtrer’s special purpose pats.④Todesign the machin productirilg planning card .It’swod to report the working process of the machine to finish the need tine the cutting capacity the machine producticity and machine’s rate for the cach activity.
(三)To design the comuination machine main axle box .To design it a cocording to the special cemoncl.It’s made up of the mational pants.As magin use is to arrange the position of all the mational axle box and transrnit the power and the motion to all the main axle by the electrical machinery or the power pants .According to the working demands of the worked pants and make it taget the demand transpont speed.The machine main axle is mode in side 400*400. It’sdraved by the mediwm drive.
(四)To desing the fixture
First to choice the forer word fixed position datum plane.It’s fixed by swing depressor fixtume structure the despower can be assured by checking computations.
