Abstract
The invention discloses a piston aluminum skirt universal arbitrary indexing inclined hole rotary drill jig which comprises a rotary table [7], wherein the table surface of the rotary table [7] is provided with two supporting rods [1], the table surface is fixed with a positioning disk [8] which is provided with a step surface, through holes are arranged in the two supporting rods [1] and internally provided with screws [4] with bottoms limited in the rotary table, the upper ends of the screws [4] are provided with nuts [3], the screws in the nuts [3] are sleeved with a pressure plate [2], a drill jig [5] used for fixing an aluminum skirt [9] is arranged between the two supporting rods [1], the center of the drill jig [5] is provided with a step hole matched with the upper part of the aluminum skirt, and the side surface of the drill jig [5] is provided with a drill hole [6] matched with the dip angle of the aluminum skirt. The invention has the advantages of high processing efficiency and low production cost.
Description
Technical field
The present invention relates to a kind of revolution drill jig of machining piston aluminium skirt, especially a kind of revolution drill jig of energy arbitrary indexing inclined hole.
Background technology
In the machining, rat holing on the boring face of cylinder, inclined-plane is often arranged, especially combination of steel roof aluminum piston skirt, the aluminium skirt is being added man-hour, not only not parallel but also out of plumb aperture of specific (special) requirements and axis is arranged, make the production of corresponding therewith frock processing small batch during production in enormous quantities, adopt the line location drilling, so also to make some directed location auxiliary moulds, and hole and produce than large deviation, special market demand variation, the corresponding frock of little making is time-consuming in batches, machining accuracy is low, the time-consuming material that takes, at the bottom of the efficiency, strengthen product development cost.
Summary of the invention
Purpose of the present invention be exactly when solving the aluminium skirt of processing combination of steel roof aluminum piston skirt efficiency low, the problem that cost is high provides a kind of efficiency height, the aluminum piston skirt universal arbitrary indexing inclined hole revolution drill jig that cost is low.
The technical solution used in the present invention is: aluminum piston skirt universal arbitrary indexing inclined hole revolution drill jig, it comprises rotary table, it is characterized in that with the table top vertical fixing two support bars being arranged on the table top of described rotary table, be fixed with positioning disk on the table top between two support bars, positioning disk is provided with the aluminium skirt and cooperates the step surface that is used for fixing the aluminium skirt, be provided with through hole in two support bars, be provided with the spacing screw rod in rotary table in bottom in the through hole, the upper end of screw rod is provided with adaptive with it nut, be set with pressing plate on the screw rod in the nut, also be provided with the drill jig that is used for fixing the aluminium skirt between two support bars, the drill jig center is provided with and the suitable stepped hole in aluminium skirt top, and the side of drill jig is provided with the aluminium skirt and requires the suitable boring of inclination angle size.
Adopt technique scheme, when the aluminium skirt of processing steel crown and aluminum skirt piston, the aluminium skirt is placed on the positioning disk, again with the fixing top of aluminium skirt of drill jig, fastening nut, two side guides will be pushed down drill jig, thereby realize fixing to the aluminium skirt, because rotary table can be done radially revolution arbitrarily, axially can in vertical 90 ° of scopes, locate arbitrarily in level, radially, the axial location precision is 2 ', solve orientation problem so well, and higher precision arranged.Product requirement inclination angle size drill bushing is arranged on the last positioning disk, with workpiece and the fixing revolution of positioning disk, just can on workpiece, hole the optional position on the workbench, this method can be produced in enormous quantities, can carry out small lot trial-production again easily, simplified the loaded down with trivial details process that designs and produces of making frock greatly, as long as processing can obtain the high accuracy processing work on plain radial drilling machine.
In sum, the invention has the beneficial effects as follows: because the present invention can directly locate also conveniently arbitrarily angled boring to the aluminium skirt, so working (machining) efficiency height of the present invention, produce low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1, support bar, 2, pressing plate, 3, nut, 4, screw rod, 5, drill jig, 6, boring, 7, rotary table, 8, positioning disk, 9, the aluminium skirt.
The specific embodiment
Aluminum piston skirt universal arbitrary indexing inclined hole revolution drill jig of the present invention, as shown in Figure 1, it comprises rotary table 7, with the table top vertical fixing two support bars 1 are arranged on the table top of described rotary table 7, be fixed with positioning disk 8 on the table top between two support bars 1, positioning disk 8 is provided with aluminium skirt 9 and cooperates the step surface that is used for fixing aluminium skirt 9, be provided with through hole in two support bars 1, be provided with the spacing screw rod 4 in rotary table in bottom in the through hole, the upper end of screw rod 4 is provided with adaptive with it nut 3, be set with pressing plate 2 on the screw rod in the nut 3, also be provided with the drill jig 5 that is used for fixing aluminium skirt 9 between two support bars 1, drill jig 5 centers are provided with and the suitable stepped hole in aluminium skirt 9 tops, and the side of drill jig 5 is provided with the aluminium skirt and requires the suitable boring 6 of inclination angle size.
The present invention uses like this, and aluminium skirt 9 bottoms are sleeved on the positioning disk 8, and top is carried out suit with drill jig 5 and fixed, and fastening nut 3 makes fixedly drill jig 5 of pressing plate 2, reaches aluminium skirt 9 is fixed.Drill bit stretches in the boring 6, can hole.
