Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
As shown in Figure 1, Figure 2, shown in Fig. 6, Fig. 7, Fig. 8, end cap flank hole fixture, comprise matrix 1 and be vertically fixed on the side plate 16 on a side end face of matrix 1, on side plate, be positioned at matrix 1 top and be provided with pedestal 3, locating shaft 2, taper pin, template, drill bushing, pressing plate 8 and power set, on side plate 16, be provided with locating hole 17 and pilot hole 18, an end face of pedestal 3 is the basal plane 28 that is parallel to side plate 16, and the other end of pedestal 3 contacts with side plate 16; Pressing plate 8 is connected with power set, and pressing plate 8 is arranged between pedestal 3 and power set; One end of locating shaft 2 is through pedestal 3 and locating hole 17 is rear and side plate 16 is fixing; Power set are arranged on the opposite of matrix 1 epipleural 16; Taper pin passes pilot hole 18 afterwards and side plate 16 is fixed, template one end is arranged on the top end face of side plate 16, drill bushing is arranged in template through template, and the other end of template stretches out and is arranged between side plate 16 and power set, and template and drill bushing are all arranged on the top of pedestal 3.
In matrix 1, include base plate 15, power set are arranged on base plate 15, the utility model is by the sliding axially of the relative basal plane of taper pin, and realize the variation of taper pin size.With end cap blank hole location, without Finish Machining Bore location, both ensure bore position requirement by adjustable taper pin, and prevented again Finish Machining Bore to cause damage, reached the object to end cap flank hole.
As shown in Fig. 1, Fig. 7, Fig. 8, the quantity of general template has one at least, and needing according to structure also can be unlikely one, called after template 1 and template 26 successively, and template 1 and template 26 are fixed on the top end face of side plate 16; Be arranged on drill bushing quantity in template corresponding by drilling hole amount with end cap, drill bushing position treats that with end cap bore position is corresponding respectively, the drill bushing called after drill bushing 1 of installing in template 1, the drill bushing called after drill bushing 2 13 of installing in template 25, realizes a set of drill jig with this and holes for the hole to diverse location.
Embodiment 2:
As Fig. 3, shown in Fig. 4, taper pin comprises the locating cone 19 connecting successively, regulate double-screw bolt 20, lead 21 and locking double-screw bolt 22, and its dead in line, locating cone 19 is circular cone structure, one end that end face diameter is larger is connected with regulating double-screw bolt 20, lead 21 is arranged in pilot hole 18 and with it and coordinates, regulate on double-screw bolt 20 and be sheathed with adjusting nut 10, on locking double-screw bolt 22, be sheathed with locking nut 11, adjusting nut 10 and locking nut 11 are separately positioned on the both sides of side plate 16, and respectively with the sidewall contact of side plate 16, adjusting nut 10 is arranged between side plate 16 and power set, on the outer wall of described adjusting double-screw bolt 20 and locking double-screw bolt 22, be provided with the parallel facet 23 of indent two.
Owing to being had certain position relation by boring and dead eye, blank hole on end cap, so, end cap flank hole fixture also must corresponding this position relationship.Fixture is to coordinate with the locating dowel of fixture locating shaft by bearing with end cover hole, and the axis of guide of locating shaft coordinates with side plate locating hole, and concentric with locating dowel; End cap blank hole coordinates with the locating cone of fixture taper pin, and the lead of taper pin and side plate pilot hole are slidably matched, and concentric with locating cone; So, the position of bearing with end cover hole and blank hole, the locating hole 17 on the side plate 16 described in being equal to and the position of pilot hole 18, be the position of the locating dowel of locating shaft and the locating cone of taper pin; The position with blank hole by boring, is equal to the position with the locating cone of taper pin by boring.So, end cap flank hole fixture has ensured the relevant position of being holed on end cap.
In the time that needs are holed, bearing with end cover hole is coordinated to location with the locating dowel of fixture locating shaft, end cap blank hole coordinates circumferentially location with the locating cone of fixture taper pin, end cap locating surface is resisted against on the basal plane of pedestal, pull active grab, promote pressing plate end cap is compressed, realize location, clamping, boring to end cap, pressing plate and active grab matched in clearance, make to clamp more reliable.
For adapting to not of uniform size the causing of end cap blank hole of every batch or different manufacturers, just need the circumferentially also respective change of size of the taper pin of location, prevent that circumferentially bore position skew is forbidden to cause in location.
Taper pin in Fig. 3 is short taper pin 4, taper pin in Fig. 4 is long taper pin 7, adapting to different length and aperture positions, locating cone is the outer cone that is provided with certain taper, the pin that can vary in size by processing, replacing carrys out the corresponding end cap blank hole causing not of uniform size, but need so the several pins that vary in size of processing, and positioning precision is subject to the impact of limited pin quantity, uses also inconvenient.
Embodiment 3:
As shown in Figure 5, locating shaft 2 comprises the locating dowel 24 connecting successively, the axis of guide 25 and fixed bolt 26, and its dead in line, locating dowel 24 is arranged in pedestal 3, the axis of guide 25 is through locating hole 17 cooperation with it, on fixed bolt 26, be sheathed with hold-down nut 9, and the sidewall contact of hold-down nut 9 and side plate 16, locating dowel 24 and fixed bolt 26 are separately positioned on the both sides of side plate 16, on the outer wall of fixed bolt 26, be provided with the parallel facet of indent two, fixed bolt 26 forms groove 27 away from the tail end indent of the axis of guide 25, locating shaft also can be welded on side plate, locating shaft 2 of the present utility model is to be connected on side plate 16 with hold-down nut 9, the locating dowel size of being convenient to like this locating shaft can be according to bearing with end cover hole match grinding, improve positioning precision.Taper pin one end is provided with locating cone, and coordinate with end cap blank hole, in the time of end cap blank hole size variation, regulate adjusting nut and the locking nut of side plate both sides, by regulating double-screw bolt and locking double-screw bolt, drive the lead arranging on taper pin to slide axially along side plate pilot hole, the locating cone concentric with lead also relative basal plane slides simultaneously, because locating cone is the outer cone that is provided with certain taper, when the relative basal plane of locating cone slides, the relative basal plane of size that is equivalent to locating cone changes, when being adjusted to locating cone and sliding into end cap blank hole gapless in the same size with adjusting nut and locking nut, adapt to the variation of end cap blank hole size, realizing locating cone circumferentially locates.
