The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
As shown in Figure 1 to Figure 3, described switch housing drilling tool comprises Working table 1, the center of described Working table 1 is provided with fixture, described fixture comprises base 21 and is fixed on the fastener on base 21, described fastener comprises pressure head 22, pressure head drives cylinder 23, described pressure head 22 connects pressure head and drives cylinder 23, and at pressure head, drive clamping switch shell under the effect of cylinder 23, and described base 21 upper foreparts are each side fixed with a location-plate 3, the left and right sides at rear portion is also provided with a pair of intilted location-plate 3, and two location-plates 3 at described rear portion are symmetrical along base plate 21 axis, described location-plate 3 is provided with pilot hole 31 being positioned on the position that switch housing need to hole, be used for guiding described drilling tool boring, described frock is provided with four bench drill tools altogether respectively over against four location-plates 3, the drill bit 41 of described drilling tool respectively with base 21 on the pilot hole 31 of four location-plates 3 arranging on a straight line, described drilling tool also comprises motor 43 Hes that drive drill bit 41 to rotate, drive drill bit 41 near switch enclosure, and the driving cylinder 42 of boring.
During described switch housing drilling tool operation, first switch housing is placed in four location-plates 3 on base 21, starting briquetting drives cylinder 23 to drive briquetting 22 to press down, switch housing is clamped, a described switch enclosure part need to drill through the hole of the anterior left and right sides and the hole on right side, rear portion, only need start the location-plate 3 of aiming at the anterior left and right sides and the three bench drill tools of aiming at rear portion right positioner plate 3 simultaneously, carry out drilling operation, the motor 43 of described three bench drill tools drives drill bit 42 to rotate, and drive cylinder 42 to drive drill bit 41 near switch housing by drill bit, drill bit 41 is through the pilot hole 31 of offering on each location-plate 3, drill through three through holes on switch housing simultaneously, another part switch housing need to drill through the hole of the anterior left and right sides and the hole in left side, rear portion, only need start the three bench drill tools of aiming at left and right sides location-plate 3 and aiming at rear portion left positioner plate 3 simultaneously, carry out equally drilling operation, complete after drilling operation, pressure head drives cylinder 23 band dynamic heads 22 to rise, switch housing is taken out, complete operation.
Described pressure head drives cylinder 23 and drill bit to drive cylinder 42 also can be replaced by driving oil cylinder.
Below only with embodiment, the utility model is illustrated, but the utility model is not limited to above-mentioned size and outward appearance illustration, more should not form any restriction of the present utility model.As long as within any improvement that the utility model is done or modification all belong to the protection domain of the utility model claim opinion.
