Technical field
The present invention relates to a kind of milling fixture, especially a kind of fixture of milling connecting rod concentric reducer end face, it comprises detent mechanism and clamp system.
Background technology
The first step manufacturing procedure of the connecting rod of internal combustion engine normally carries out milling to its large and small end surface, for later process processing provides a datum level.Because the shaft of connecting rod is (large, part between microcephaly) without metalworking requirement, so generally all come it large using the shaft of connecting rod as positioning datum, little end surface carries out milling, its localization method is, one side of the shaft of connecting rod is shelved on a spacer pad, the another side pushing down the shaft of connecting rod again makes connecting rod fix, spacer pad is fixed on vertical knee-type milling machine workbench, the height of adjustment vertical knee-type milling machine workbench, milling cutter is rotated between the plane of formation and described spacer pad and has a suitable distance, then large to connecting rod, little end surface carries out milling.This localization method has certain defect, because each connecting rod cast out, the thickness of its shaft can not ensure unanimously, due in batch processes, it is constant that milling cutter rotates the distance between plane and spacer pad formed, therefore major part or little end surface and shaft thickness to be caused after milling inconsistent to size between point face, has influence on efficiency or the quality of later process processing.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of fixture of milling connecting rod concentric reducer end face, and this fixture can ensure that the big end of milling or little end surface and shaft thickness are to consistent size between point face.
The structure of this fixture comprises substrate 1, be fixed on detent mechanism 2 on substrate and clamp system 3, described clamp system comprises the guide way 33 be fixed on substrate, is placed in the slide block 31 of guide way, the first screw rod 32 screwed in slide block, one end of the first described screw rod is arranged in the first gripper shoe 11, gripper shoe is vertically fixed on one end of substrate, the other end of substrate is vertically fixed with the second gripper shoe 12, rotating the first screw rod can make slide block move relative to the second gripper shoe, thus clamping connecting rod 4; It is characterized in that, described detent mechanism comprises gusset 24, the vertical component effect of gusset is fixedly connected on substrate, one end of second screw rod 21 is arranged in the horizontal part of gusset, and the second screw rod is provided with one section of dextrorotation screw thread 25 and one section of derotation screw thread 26, and dextrorotation screw thread is equal with the pitch of derotation screw thread, first fixture block 22 is spun on dextrorotation screw thread, second fixture block 23 is spun on derotation screw thread, the first fixture block and the second fixture block can be made to move in opposite directions, thus clamp the shaft of connecting rod when rotating the second screw rod.
The detent mechanism of this fixture adopts dextrorotation screw thread and the shaft of derotation helicitic texture to connecting rod to position, regardless of the error of shaft thickness, all can make shaft thickness the distance that point face to rotate relative to milling cutter between the plane that formed is consistent, ensure that the connecting rod end face after milling and shaft thickness are to consistent size between point face.

Detailed description of the invention
Now to reference to accompanying drawing, the specific embodiment of the present invention is described.
A kind of fixture of milling connecting rod concentric reducer end face comprises substrate 1, be fixed on detent mechanism 2 on substrate and clamp system 3.
Described clamp system comprises the guide way 33 be fixed on substrate, guide way is provided with groove, be placed in the slide block 31 of guide way groove, the groove of part and guide way that slide block is arranged in guide way groove matches, the first screw rod 32 is rotary with in slide block, first screw flight is trapezoidal thread, one end of first screw rod is arranged in the first gripper shoe 11, the first screw portion being positioned at the first gripper shoe two sides is provided with flange, to prevent the first screw rod vibration vertically, first gripper shoe is vertically fixed on one end of substrate, the other end of substrate is vertically fixed with the second gripper shoe 12, the microcephaly of connecting rod 4 is against on the plate face of the second gripper shoe, the major part of connecting rod is towards slide block, rotating the first screw rod can make slide block move relative to the second gripper shoe, thus clamping connecting rod 4.
The cross section that described slide block is arranged in the part of guide way groove is rectangle; For anti-limited slip block offsets along short transverse when clamping, be provided with chimb in the bottom of slide block, slide block is arranged in the cross section of the part of guide way groove for " convex " font.
For clamping connecting rod more reliably, the plate face of the second gripper shoe is provided with the second vee-block 13, the top being provided with the first vee-block 12, first vee-block and the second vee-block in one end of slide block is provided with V-shaped groove.
