Abstract
The utility model discloses a drill jig for machining an oil distribution shaft of a hydraulic motor. The drill jig comprises a positioning body, a drill jig plate, a fastening screw, a first fixed drill bushing, a second fixed drill bushing, fine tuning screws and a third fixed drill bushing and is characterized in that the positioning body is welded to the drill jig plate; the first fixed drill bushing, the second fixed drill bushing and the third fixed drill bushing are in interference fit with the drill jig plate; the fastening screw is arranged in the first fixed drill bushing; and the fine tuning screws are arranged in screw holes on two sides of the drill jig plate. The drill jig is mainly used for guiding tools to drill and ream holes in workpieces.
Description
Technical field
The utility model relates to a kind of drill jig, relates in particular to a kind of hydraulic motor oil distribution shaft processing drill jig, and it is to guide cutter to hole on workpiece and the cover sheet type drill jig of the use that reams.
Background technology
Traditional hydraulic motor oil distribution shaft turnover machining of oil hole method is to adopt the boring of line mark, and cutter easily tilts in process, thereby can't guarantee the positional precision in processed hole, and drilling efficiency is low, requires higher to process operation person technical merit.
Summary of the invention
The purpose of this utility model is to provide a kind of drill jig of hydraulic motor oil distribution shaft processing (boring) use, with the positional precision that guarantees the processing work hole be controlled at ± 0.2mm in, improve the efficient of boring, eliminate the different crudy standard disunities that form because of the process operation person.
For achieving the above object, the utility model technical solution is: a kind of hydraulic motor oil distribution shaft processing drill jig, comprise positioning body 1, bushing plate 2, trip bolt 3, fixedly drill bushing 1, fixedly drill bushing 25, micrometer adjusting screw 6 and fixing drill bushing 37, it is characterized in that: described positioning body 1 and bushing plate 2 welding, fixedly drill bushing 1, fixedly drill bushing 25, fixedly drill bushing 37 and bushing plate 2 interference fit, trip bolt 3 is arranged on fixedly in drill bushing 1, and micrometer adjusting screw 6 is installed in the screw hole of bushing plate 2 both sides.
The beneficial effects of the utility model are:
1, embedded fixedly drill bushing on drill jig, tool setting has guide effect, prevents that cutter from tilting in process, and cutter even fractures.
2, positioning body with after workpiece coordinates, has the regulated quantity of 0.1 millimeter, without clamp body, after adjusting directly by trip bolt and workpiece fastening location.
Above-mentioned hydraulic motor oil distribution shaft is realized Drilling operation with drill jig, has guaranteed the positional precision of holing to have improved production efficiency, is applicable to accurately produce in enormous quantities.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional schematic of Fig. 1.
In figure: 1---positioning body, 2---bushing plate, 3---trip bolt, 4---fixedly drill bushing one, 5---fixedly drill bushing two, 6---micrometer adjusting screw, 7---fixedly drill bushing three.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-2, the utility model comprises positioning body 1, bushing plate 2, trip bolt 3, fixedly drill bushing 1, fixedly drill bushing 25, micrometer adjusting screw 6, fixing drill bushing 37, it is characterized in that: described positioning body 1 and bushing plate 2 welding, fixedly drill bushing 1, fixedly drill bushing 25, fixedly drill bushing 37 and bushing plate 2 interference fit, trip bolt 3 is arranged on fixedly in drill bushing 1, and micrometer adjusting screw 6 is installed in the screw hole of bushing plate 2 both sides.
The internal diameter of described bushing plate 2 assembles mutually with the external diameter of hydraulic motor oil distribution shaft, and positioning body 1 is located with the shift fork hole assembling (adjusting) of hydraulic motor oil distribution shaft, and micrometer adjusting screw 6 is regulated, then trip bolt 3 and hydraulic motor oil distribution shaft are tightened.
The fixedly drill bushing 1 that arranges according to the position distribution in processed hole, fixedly drill bushing 25, fixedly drill bushing 37 and bushing plate 2 in order to determining the position of cutter, and prevent cutter in the process medium dip, thereby guarantee the positional precision in processed hole.
