Description

A kind of machining large screw box flank of tooth inclined oil hole of air drill jig

Technical field

The utility model belongs to plant equipment manufacturing technology field, relates to a kind of machining large screw box toothFace inclined oil hole of air drill jig.

Background technology

Conventionally the inclined oil hole of air of the machining large screw box internal circular surfaces flank of tooth, is all by pincers worker electric hand drill handWork processing. Although the required precision of inclined oil hole of air is not high, the inclined oil hole of air on the flank of tooth is oblique, and depresses spiral shellFemale axial line has certain angle, and pincers worker is difficult to Artificial Control, very possible boring partially, with screw boxMain oil-hole bores obstructed, once and bore partially very difficult reparation.

Therefore, develop a kind of applicable instrument, seem especially urgent.

Utility model content

The purpose of this utility model is to provide a kind of machining large screw box flank of tooth inclined oil hole of air drill jig, separatesThe prior art of having determined adopts manual operation, with the manual processing of electric hand drill, makes the large-scale screw box flank of tooth obliqueThe problem of machining of oil hole difficulty.

The technical scheme that the utility model adopts is that a kind of machining large screw box flank of tooth inclined oil hole of air is usedDrill jig, drill jig is an elongate in shape and is longitudinally processed with multiple teeth in interval at lower surface, shows from drill jigFace tilts to have drilled through one to the jig section of each tooth leads boring, each leading on boring and the screw box flank of toothThe angle of inclined oil hole of air to be processed is consistent.

Machining large screw box flank of tooth inclined oil hole of air drill jig of the present utility model, is further characterized in that:

The quantity of tooth is greater than the number of teeth of the screw box flank of tooth to be processed, and the transverse tooth thickness of tooth is less than screw boxThe axial width of teeth groove.

The front flank of tooth of each tooth is all vertical with the longitudinal centre line of drill jig with the rear flank of tooth, or, the tooth pitch of tooth,The tooth pitch of profile of tooth and the screw box flank of tooth, the size of profile of tooth are consistent.

The beneficial effects of the utility model are to use this instrument can process simply, fast, accurately pressureLower nut flank of tooth inclined oil hole of air, reduces difficulty, improves precision.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

As shown in Figure 1 and Figure 2, the utility model has adopted a kind of drill jig 1, and the structure of drill jig 1 is,Drill jig 1 is an elongate in shape and is longitudinally processed with multiple teeth 6 in interval at lower surface, (in drill jig 1 following tableFace is processed with multiple teeth 6), from drill jig 1 upper surface to each tooth 6 flank of tooth (jig section C) tiltDrill through one and led boring 5, eachly led inclined oil hole of air 3 to be processed on boring 5 and screw box 2 flank of toothAngle consistent.

As shown in Figure 5, Figure 6, the quantity of tooth 6 is greater than the number of teeth of screw box to be processed 2 flank of tooth,The front flank of tooth of each tooth 6 is all vertical with the longitudinal centre line of drill jig 1 with the rear flank of tooth (jig section C), alsoTooth pitch, profile of tooth and the tooth pitch of screw box 2 flank of tooth, consistent (this of size of profile of tooth that can tooth 6Although sample tooth 6 is tight with screw box 2 teeth groove laminatings, the cost of manufacture of drill jig 1 is also high);The transverse tooth thickness S of tooth 6 is slightly less than the axial width T of the teeth groove of screw box 2, and difference gap is δ between the two.

Because inclined oil hole of air 3 is not very high as the position accuracy demand of oilhole own, with main oil-hole 4Drill through, will greatly strengthen manufacture difficulty and cost and spirality is processed into in the tooth portion of drill jig 1,Screw box 2 each teeth groove and the flank of tooth are spiral, each tooth 6 front and back flank of tooth be plane instead ofSpiral, so be processed into straight-tooth as long as drill jig 1 center line is alignd with main oil-hole 4 center lines, makeTip surface M on jig section C contacts with screw box 2 flank of tooth, and all leading holes 5, to be processed obliqueOilhole 3 and main oil-hole 4 center lines are coplanar, just can realize location, and drill jig 1 axle in useTo not stressing.

With reference to Fig. 3, Fig. 4, operation principle of the present utility model is,

Before boring, first drill jig 1 is placed on the screw thread of screw box 2, adjusts drill jig 1 and make drill jig 1The axis parallel of longitudinal centre line and main oil-hole 4, in the teeth groove of each screw box 2, clamping has oneIndividual tooth 6, each tooth 6 is led jig section C and screw box 2 inclined oil hole of air to be processed at boring 5 internal orifice placesThe flank of tooth correspondence (near still not touching) at 3 import places;

Then, the tip surface M on jig section C is contacted with screw box 2 flank of tooth, with pressing plate by drill jig1 fastens;

Finally, pincers worker gets out respectively along the 5 pairs of each teeth groove of screw box 2 of boring of leading of each tooth 6 successivelyIndividual inclined oil hole of air 3, realizes the processing of all inclined oil hole of air 3 in screw box 2.

Device of the present utility model, simple in structure, simple to operate, cost of manufacture is low, easy to manufacture, largeReduce greatly the difficulty of processing of inclined oil hole of air 3 on screw box 2 flank of tooth, improved the machining accuracy of oilhole.
