Description
Technical field
The utility model relates to a kind of hole drilling die, particularly a kind of hole drilling die for the left and right pivoted arm frame of excavator.
Background technology
At present, left and right pivoted arm frame is the large-scale key components and parts of excavator, it is the cast steel blank, because profile is peculiar, shape misconduct, bulk are larger, the bolt hole in processing one week of end face, existing method are after adopting Digit Control Machine Tool to bore the good position hole, to forward on the drilling machine and process, and workpiece is bad putting also, processing is difficulty very, proofread and correct, the centering workpiece carries out numerical control programming and process this bolt hole, and working (machining) efficiency is extremely low, quality is difficult to again guarantee, be easy to produce waste product, the economy of company caused loss, so prior art is still perfect not.
The utility model content
The purpose of this utility model is: provide a kind of hole drilling die for the left and right pivoted arm frame of excavator that a kind of simple in structure, practical, clamping location is quick, can guarantee left and right pivoted arm frame borehole accuracy, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of hole drilling die for the left and right pivoted arm frame of excavator, comprise base, be provided with positioning round table at base, be provided with studs and bushing plate on the positioning round table, at studs pressing plate and hex nut are installed, are provided with the drill jig hole at bushing plate, in the drill jig hole, be provided with fixedly drill bushing, one end of bushing plate is connected with location-plate by six circumference chapiter screws, is provided with directed mandrel at location-plate.
Be provided with the directed core axle hole that can insert directed mandrel at location-plate.
Be provided with the handle that conveniently lifts at directed mandrel.
Owing to adopted technique scheme, pivoted arm frame that at first will be to be holed is placed in vertical direction location on the base positioning round table, then the endoporus of bushing plate is penetrated on the dome platform and end face that the pivoted arm frame processed, again directed mandrel is penetrated in the plate hole of location and in the pivoted arm frame hole, make its horizontal direction location, the rotation hex nut makes pressing plate fasten bushing plate and workpiece, just can hole to the pivoted arm frame by common driller, compared with prior art, the utility model not only has simple in structure, advantage easy to process, and design ingenious, safe and reliable, the clamping location is quick, can guarantee pivoted arm frame borehole accuracy, the advantage such as increase work efficiency.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind of hole drilling die for the left and right pivoted arm frame of excavator, comprise base 1, be provided with positioning round table 2 at base 1, be provided with studs 3 and bushing plate 4 on the positioning round table 2, at studs 3 pressing plate 5 and hex nut 6 are installed, are provided with drill jig hole 7 at bushing plate 4, in drill jig hole 7, be provided with fixedly drill bushing 8, one end of bushing plate 4 is connected with location-plate 10 by six circumference chapiter screws 9, is provided with directed mandrel 11 at location-plate 10.
Be provided with the directed core axle hole 12 that can insert directed mandrel 11 at location-plate 10.
Be provided with the handle 13 that conveniently lifts at directed mandrel 11.
During the utility model work, pivoted arm frame 14 that at first will be to be holed is placed in vertical direction location on base 1 positioning round table 2, then the endoporus of bushing plate 4 is penetrated on the dome platform and end face that pivoted arm frame 14 processed, again directed mandrel 11 is penetrated in the directed core axle hole 12 and pivoted arm frame aperture in, make its horizontal direction location, hex nut 6 compresses bushing plate 4 and workpiece with pressing plate 5 on the studs 3 by being rotatably provided in, after fixing, just can carry out Drilling operation to pivoted arm frame 14 by common driller, the part that processes not only machining accuracy can reach drawing requirement fully, and improved the working (machining) efficiency of part, saved the time, reduced percent defective, be worthy to be popularized.
