Description
Technical field:
The present invention relates to machining fixture, particularly a kind of bent axle double end milling machine drill jig.
Background technology:
Bent axle is respectively disjunctor cam body of mediate cylindrical, both sides, and bottom, two cam body both sides is limit cylinder that misplaces with the mediate cylindrical axial line of disjunctor extension respectively.
The first operation is that cylinder outer face, limit, the blank left and right sides is carried out face milling at lathe with two milling cutters, and milling cutter retreats after the milling, and the drill bit of both sides drilling machine is advanced simultaneously in opposite directions, and the outer face is drilled centre bore.Must fix with anchor clamps before the machined.Existing clamp structure is downward opening " door " font workbench, fixes four V-shape bases on the table top.V-shape base is that an inverted T-shaped piece, a side are fixed an opening towards the vee-block of side.The purpose of vee-block split setting is: for the workpiece of different-diameter, breach is little as long as change vee-block, and needn't integral replacing.The interval is fixed on the workbench two V-shape bases in order to locate in the same way, and two V-shape base intervals are fixed on the slide plate in addition, and both sides vee-block V-shaped part is symmetrical in opposite directions, and the slide block both sides are fixed with the siding track bar.A cylinder piston rod front end is fixed a transverse bar, and the transverse bar both ends are linked in two fixing on the face of slide plate outer steel rings.During the clamping blank, hand-held blank leans against in two location V-shape base V-shaped parts, and the cylinder slip V-shape base that drives on the slide plate of advancing moves ahead, and is fitted in blank cylindrical opposite side, then can carry out machined for clamped condition.
The defective of this structure is: although cylinder with a pair of vee-block clamping of every side work because workpiece is blank, surface imperfection, wherein a pair of vee-block of a side and workpiece only have two points to be in the state of overlaying sometimes, this be that void is pressed from both sides.And for single V-shaped part, if limit cylinder blank cylindrical has tapering, a part that then only overlays large footpath cylindrical also is empty folder.Under void folder state, might destroy this empty balance when the lathe Milling Force is large.Secondly, when the blank diameter there are differences, because the location of location V-shape base makes the cylindrical axial line in both sides move or inside contract outward, then during the later process drill centers, the drill bit axial line is located, make centre bore produce displacement, thereby impact produce eccentric car phenomenon processed when both sides cylinder cylindrical car is processed.
Summary of the invention:
The object of the invention is to overcome defects, a kind of bent axle double end milling machine drill jig is provided.
The solution of the present invention is: comprise workbench, cylinder, transverse bar, V-shape base, it is characterized in that: two transformation of the way forming V-shape spring supports in four V-shape bases, the V-arrangement elastic seat structure is that center, the vee-block back side is provided with the ball recess less than semicircle, on inverted T-shaped piece and the vee-block binding face the corresponding ball recess less than semicircle is set also, the steel ball that radius equals the ball recess radius is fitted in vee-block, in two ball recess of inverted T-shaped piece, vee-block, the vertical plate of inverted T-shaped seat two sides are respectively arranged with up and down two screwed holes, screw up in each screwed hole and be fixed wtih screw, four extension spring two ends are hooked on respectively vee-block, the inverted T-shaped seat is between the two on the contour screw in corresponding both sides; Be fixed with middle guide base plate and equally spaced two side rails base plates on the table surface, two planar central that surround at each middle guide base plate of table surface second half section and adjacent two side rails base plates are respectively arranged with the back segment center through hole, two middle parts with shaft part under the double end Step Shaft of the shaft shoulder respectively fit be fixed in two back segment center through hole, the shaft part cylindrical overlaps a unification gear movingly on the Step Shaft; Fix a passive tooth bar that is meshed with gear in each gear and middle guide base plate clearance space, be sheathed with movingly the active tooth bar that is meshed with gear in each gear and side rails base plate clearance space, initiatively tooth bar first half section is rectangular slab; Fix a central guide rail that the cross section is T-shaped at the middle guide plate upper surface, on two side rails base plates, fix respectively the limit guide rail that a cross section is inverted L-shaped, other is provided with the slide block that four cross sections are convex shape, be sheathed with respectively former and later two slide blocks between one-sided middle guide and the limit guide rail, side, slide block one side stage rank is linked in the cavity that side rails base plate and limit guide rail surround movingly, and slide block opposite side step side is enclosed within the cavity that middle guide base plate and central guide rail surround movingly; Two active tooth bar first half sections are fixed on the lower surface of left front slide block, right front slide block with dormant bolt respectively; Two passive tooth bars are fixed on the lower surface of left back slide block, right back slide block with dormant bolt respectively; Left front slide block, right front slide block are possessed spacing, left front slide block, right front slide block upper surface are fixed with respectively V-shape base, left back slide block, right back slide block are possessed spacing, and left back slide block, right back slide block upper surface are fixed with respectively the V-arrangement spring support, and one-sided V-shape base and V-arrangement spring support V-notch are each other in opposite directions; Right front slide block, left front slip front face are fixed with respectively a steel ring, and the horizontal push rod both ends of cylinder piston rod front end are linked in respectively in the steel ring inner circle of two slip front faces.
The invention has the advantages that: when going behind two slide blocks of cylinder promotion, two slide blocks go in the same direction in addition, and every pair of vee-block equidistantly moves and guaranteed that the Clamping Center line is constant, and V-arrangement spring support vee-block can be done automatic adjusting simultaneously, and holding area is large.
