Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail, but not as limitation of the present invention.
Embodiments of the invention: a kind of preparation method ensureing clamp bar class part end face machining accuracy fixture, described fixture comprises reference block and clamp, first CNC milling machine is utilized to process locating platform on reference block, then carving machine carve main scale scale and secondary chi scale on the locating platform of reference block and the periphery of clamp is respectively utilized, punch in the centre of reference block, bearing pin is provided with in hole, being arranged on by clamp on bearing pin makes clamp bottom surface be arranged on locating platform, ensure that clamp and reference block can relatively rotate, clamp is produced the part mounting table paralleled with the locating platform of reference block, last producing on clamp can by locking device locked for part, like this part to be processed is placed on part mounting table, machining angle is obtained by the secondary chi scale adjusting clamp, guarantee machining accuracy.
Locking device is lock-screw.
Reference block is square or rectangle, and the shape of clamp is " recessed " shape.
A kind of fixture ensureing clamp bar class part end face machining accuracy, described fixture comprises reference block 1 and clamp 2, reference block 1 is provided with locating platform 3, reference block 1 is provided with main scale scale 5, clamp 2 is connected with reference block 1 by bearing pin 4, clamp 2 is provided with part mounting table 6, the periphery of clamp 2 is provided with secondary chi scale 7; Clamp 2 is provided with locking device 8.
Clamp 2 and reference block 1 can relatively rotate.
Locking device 8 is lock-screw 9.
Clamp 2 is provided with two lock-screws 9.
Reference block 1 is square or rectangle, and the shape of clamp 2 is " recessed " shape.
Main scale scale is be engraved in the scale on reference block 1, secondary chi scale is be engraved in the scale on clamp 2 periphery, profile due to reference block is square, datum plane all can be made in its four limits, scale on reference block is vertical with datum plane, rotate clamp (secondary chi) alignment fiducials block high scale (main scale) exactly during adjustment angle, obtain angle needed for workpiece and both can.
In use process of the present invention, reference block 1 is equivalent to main scale, clamp 2 is equivalent to secondary chi, the part mounting table 6 of clamp 2 is equivalent to positioning reference plane, when chi of working, lock-screw 9 is equivalent to the clamping screw on work chi, is so not only convenient to reference block location, centering but also can makes that part is relative with reference block to be rotated, guarantee cutting angle.Fixture high scale is accurate to " dividing ", ensures that machining needs angle.
The present invention includes following job step:
1) workpiece is put on clamp positions;
2) angle (73 ° 54 ') needed for clamp and reference block to workpiece is rotated;
3) fixture clipping workpiece is put on wire cutting machine tool position, clamp, centering, the another one normal angles (93 ° 30 ') of cut workpiece.
We carry out survey to 100 with the workpiece that these class methods are processed, and find that the repair rate caused by processing method reason is reduced to zero.
The following drawings is the comparison diagram processed part after improving front and improvement:
By the utilization of fixture, repair rate when linear cutter wide-angle or processing space angle workpiece is reduced to zero, and substantially increases efficiency, shortens the Mould Machining cycle.The line no longer needing pincers worker to coordinate no longer to need with the naked eye to aim at when line, Linear cut centering pincers worker to draw, because processing left and right part angle is ensured by fixture, well can ensure the uniformity of left and right part.
