Description
Technical field
The utility model relates to the positioner in a kind of machining, particularly the positioner of a kind of turbocharger middle body on numerically controlled lathe.
Background technology
In the process of turbocharger of motor intermediate, its booster intermediate body has certain original positioning datum structure, as the position of datum level, shape, size etc.The turbocharger middle body 7 that the model of U.S. HONYWELL company is 804071, on the circumference that its positioning datum structure is is 29 millimeters places at distance booster intermediate body nose circle face central point 13 radiuses, three facets that inwardly concave are set, comprise that the faceted width of the curving of castings only has 15 millimeters.In the middle of three facets that inwardly concave, three circular locating surfaces that diameter is 6 millimeters of φ are all arranged.The nose circle face positioning reference plane 16 that these three circular locating surfaces are exactly this turbocharger middle body.Although this nose circle face datum level is on same circumference, on circumference, not on trisection posistion, the center line of turbocharger middle body oil drain out 10 of take is datum line 12, and this datum line is also through the central point 13 of above-mentioned nose circle face.First nose circle face datum level 16 is arranged on datum line and turns left 12 ° to locate.Second nose circle face datum level 16 is arranged on datum line 12 and turns left 128 ° to locate.The 3rd nose circle face datum level 16 is arranged on 108 ° of datum line 12 right-hand rotations and locates.In use, because the race diameter of booster intermediate body is 160 millimeters of φ, and three nose circle face datum levels 16 of its booster intermediate body only have 29 millimeters apart from booster intermediate body nose circle face central point 13, and this nose circle face datum level 16 is that operating personnel can't see nose circle face datum level while on oild chuck 9, locating mounting board.Be that operating personnel can't see three nose circle face datum levels 16 when on the numerically controlled lathe oild chuck, booster intermediate body being installed.Can only be with the contact position of feeling to come positioner on the nose circle face datum level of centering booster intermediate body and lathe of hand during installation.The faceted width that comprises the curving of castings because of the nose circle face datum level place of booster intermediate body only has 15 millimeters again, and its three nose circle face datum levels 16 are not the trisection settings on same circumference.How booster intermediate body is located on the machine tool hydraulic chuck to mounting board more difficult.Can only be after oild chuck clamps the booster intermediate body external diameter with oild chuck commonly used, while rotating booster intermediate body, whether its end face beats larger, if oild chuck clamps and while rotating booster intermediate body its end face run-out large, just need readjust the location mounting board.Until the clamped rear ending pulsation of booster intermediate body could determine that in the allowed band of 0.5 millimeter the booster intermediate body installation site is correct.According to the practical operation situation, see, operating personnel sometimes will adjust and just can complete booster intermediate body for three to four times locate mounting board work on oild chuck.This has just greatly reduced the processing work efficiency.
Summary of the invention
The purpose of this utility model is to provide the positioner of a kind of turbocharger middle body on numerically controlled lathe.This positioner can make turbocharger middle body fast positioning clip card on oild chuck, can greatly improve the machining work efficiency to turbocharger.
The technical solution of the utility model is: the positioner of a kind of turbocharger middle body on numerically controlled lathe.One oild chuck is installed on numerically controlled lathe, and oild chuck is driven and moves by the machine tool hydraulic pull bar.Three claws are installed in the chuck chute of trisection setting on oild chuck.After on booster intermediate body is packed oild chuck into, three claws are slidably clamped the outer ring arc face of booster intermediate body.Fixedly mount a positioning seat by screw A in the middle of three claws on oild chuck.Be provided with three origin reference location posts on positioning seat.These three origin reference location posts and three corresponding settings of nose circle face datum level on booster intermediate body nose circle face, booster intermediate body is correct install after, three origin reference location posts are with together with three nose circle face datum levels closely abut against.The top circular hollow centering round platform that also is provided with of positioning seat, this circle hollow centering round platform outer ring is slightly less than the centre bore inner ring in the middle of turbocharger middle body.While on oild chuck, turbocharger middle body being installed, hollow centering round platform stretches in centre bore.Be provided with hole slot on positioning seat in the middle of circular hollow centering round platform.Determine the flat column in angle and be fixedly mounted on by screw B in the hole slot of positioning seat, this bore of determining the flat column in angle is slightly less than the bore of booster intermediate body oil drain out.While on oild chuck, turbocharger middle body being installed, the flat column of Qi Dingjiao top is stretched in oil drain out.
Operation principle of the present utility model and process are: when turbocharger middle body is installed, first the centre bore of turbocharger middle body is sleeved on to centering round platform outer ring, then oil drain out is sleeved on and determines on the flat column in angle.Through the centering round platform and the turbocharger middle body after determine the flat stud location in angle just be on correct installation site, then three nose circle face datum levels that turbocharger middle body made to turbocharger middle body toward oild chuck direction promotion are with together with three origin reference location posts abut against.Again, the machine tool hydraulic pull bar pulls three claws to make three centripetal slips of claw clamp the outer ring datum level of booster intermediate body.So far just completed the clip location work to turbocharger middle body.After numerically controlled lathe completes the processing work of turbocharger middle body, the above-mentioned installation steps of reverse operation just can unload turbocharger middle body from numerically controlled lathe.Repeat above-mentioned action and just liaison turbocharger middle body is carried out to machining work fast.
The utility model has the advantages that the positioner of a kind of turbocharger middle body on numerically controlled lathe is provided.This positioner can make turbocharger middle body fast positioning clip card on oild chuck, can greatly improve the machining work efficiency to turbocharger.
