Abstract
The utility model provides a drilling nozzle drilling frock belongs to industrial steam turbine nozzle field, including the bush, the slope of bush top surface, the bush side is connected with drill bushing frame and clamp plate frame, is equipped with drilling on the drill bushing frame, is equipped with the clamp plate on the clamp plate frame, is equipped with the pivot on the bush top surface, is equipped with bolt, carousel clamp plate and carousel in the pivot from top to bottom in proper order, needs the work piece of drilling to fix on the carousel, and it has the triangle -shaped cushion to press between clamp plate and the carousel, can avoid the drill bit to break in drilling process.
Description
Technical field
This utility model provides a kind of boring nozzles drilling tool, belongs to industrial turbine machine nozzle field.
Background technology
The nozzle of low capacity industry dragging steam turbine is as shown in Figure 3, the hole of its leading edge is that drill bit vertically pierces, boring procedure is very simple, and the inclined hole of its lagging edge is the inclined hole with certain taper, needs special forming drill during the hole machined of this type, the cost of manufacture of this kind of drill bit is higher, because centerline hole angle of inclination is relatively big, so piercing in process at drill bit, it is easy to cause broken drill, cause production cost to increase, and have a strong impact on production efficiency.
Utility model content
This utility model purpose is in that to provide a kind of boring nozzles drilling tool, it is possible to avoid drill bit will not fracture in boring procedure.
Boring nozzles drilling tool described in the utility model, including lining, lining top surface inclination, lining side is connected to drill bushing frame and pressing plate frame, and drill bushing frame is provided with boring, and pressing plate frame is provided with pressing plate, lining end face is provided with rotating shaft, rotating shaft is sequentially arranged with bolt, rotating disk pressing plate and rotating disk from top to bottom, it is necessary to the workpiece of boring is fixed on rotating disk, between pressing plate and rotating disk, is pressed with triangle cushion block.
Described boring nozzles drilling tool, for processing the nozzle of steam turbine, owing to trailing edge has gradient, so, the angle of lining end face and the angle of rotating disk are identical, drill bit is that level pierces, and is compressed tightly against on nozzle by pressing plate by triangle cushion block, makes drill bit when piercing, drill together with triangle cushion block, what the combination of such triangle cushion block and nozzle made the centrage in hole and drill bit pierces direction conllinear, counteracts the power making drill bit bend, it is ensured that drill bit will not fracture.
Described boring nozzles drilling tool, rotating disk pressing plate is provided with protractor, and rotating disk is carved with the groove representing angle indicator.Owing to needs bore multiple hole, the spacing between each hole is identical, it is possible to make staff better grasp angle.
This utility model compared with prior art has the beneficial effect that
Described boring nozzles drilling tool, for processing the nozzle of steam turbine, owing to trailing edge has gradient, so, the angle of lining end face and the angle of rotating disk are identical, drill bit is that level pierces, and is compressed tightly against on nozzle by pressing plate by triangle cushion block, makes drill bit when piercing, drill together with triangle cushion block, what the combination of such triangle cushion block and nozzle made the centrage in hole and drill bit pierces direction conllinear, counteracts the power making drill bit bend, it is ensured that drill bit will not fracture.
