Abstract
The utility model relates to a drill jig for processing weep holes on a damping ring of a water turbine generator. The center of a drill jig base is provided with an arc-shaped inner cavity, three inner circular-arc positioning pins, a positioning plate and a horizontal positioning screw; the arc-shaped inner cavity is matched with a damping ring semi-finished product; the top of the arc-shaped inner cavity is open; the three inner circular-arc positioning pins are adjoined to the inner arc of the damping ring semi-finished product; the positioning plate is arranged at one end of the drill jig base; and the horizontal positioning screw closely supports the outer arc of the damping ring semi-finished product along a symmetric center line. A template is fastened and mounted on the top surface of the drill jig base through a template positioning pin and a first bolt and is in clearance fit with the damping ring semi-finished product, wherein the damping ring semi-finished product is arranged in the arc-shaped inner cavity of the drill jig base; the drill sleeve of a screw rod hole is embedded at the two ends of the template; the drill sleeves of damping rod holes which are arranged along an arc are embedded in the middle of the template; vertical positioning bolts which closely support the damping ring semi-finished product are arranged at the two ends of the template; and two positioning plug pins which are in transition fit with the drill sleeves of the damping rod holes are arranged. The drill jig can replace the process that each hole is drawn firstly and then drilled, the drill jig ensures shaped and positional accuracy of each hole, and has the advantages of time saving, labor saving, high work efficiency and low cost.
Description
Technical field
The utility model relates to a kind of drilling machine processing mold, particularly a kind of drill jig of process water turbine generator damping ring round.
Background technology
Before this, the screw hole 15 that the damper rod hole 16 and the two ends along the circular arc arrangement of processing hydrogenerator damping ring 14 as shown in Figure 3-4 connect usefulness, the general employing earlier rule, again boring; Complex procedures, process-cycle are long, labour intensity is big and be difficult to guarantee the shaped position precision in each hole, and deviation is big; Cause two ends attachment bolt and damper rod that not contraposition is installed.
Summary of the invention
The purpose of this utility model has provided a kind of drill jig of process water turbine generator damping ring round, can guarantee the shaped position precision in each hole, and operation is simple, the cycle is short, work efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of drill jig of process water turbine generator damping ring round comprises jig seat and the screw hole to be processed arranged along circular arc and the damping ring semi-finished product in damper rod hole; The central authorities of described jig seat are provided with the arc inner chamber of the open-top that matches with the half-finished profile of damping ring, described arc inner chamber be provided with damping ring half-finished in circular arc near 2-5 in the circular arc alignment pin.One end of described jig seat is provided with the location-plate of installing by the second bolt tightening, is provided with the horizontal location screw that presses closer damping ring semi-finished product external arc along symmetrical center line in the central authorities of described jig seat.Template by the Template Location pin and first bolted be installed in jig seat end face and with the damping ring semi-finished product matched in clearance that is contained in jig seat arc inner chamber, be embedded in the two ends of template according to damping ring designing requirement processing and the screw hole drill bushing arranged, according to damping ring designing requirement processing with arrange and be embedded in the middle part of template along the damper rod hole drill cover that circular arc is arranged.The two ends of template are provided with between screw hole drill bushing and damper rod hole drill cover and press closer the half-finished vertical bolt of damping ring.Be provided with two fastening screws with described damper rod hole drill cover interference fits; Described arc inner chamber be provided with damping ring half-finished in circular arc near three interior circular arc alignment pins.
The beneficial effects of the utility model are: adopt the utility model, replace the technology that traditional each hole line earlier to arranging along circular arc is holed again, have the shaped position precision of guaranteeing each hole, operation is simple, save time, laborsaving, work efficiency is high and cost is low advantage.
