Description

Quick positioning and punching device for processing casting of large wind driven generator Technical Field The utility model relates to the technical field of drilling and positioning devices for cast parts such as wind driven generator hubs and frames, in particular to a rapid positioning and punching device for machining cast parts of a large wind driven generator. Background The wind driven generator is an electric power device which converts wind energy into mechanical work and drives a rotor to rotate and finally outputs alternating current. The wind driven generator generally comprises wind wheels, a generator, a direction regulator, a tower, a speed limiting safety mechanism, an energy storage device and the like. And special parts of the hub and the frame of the cast part of the wind driven generator usually need to be marked and perforated. However, scribing and punching are time-consuming and labor-consuming, so that a device is continuously developed to realize rapid positioning and punching on the hub and the frame of the cast part of the wind driven generator. Disclosure of utility model The utility model provides a rapid positioning and punching device for processing a casting part of a large wind driven generator, which solves the problems of time and labor waste in scribing and punching of a traditional casting part hub and a frame of the wind driven generator in the background technology. In order to solve the existing problems, the utility model provides a rapid positioning and punching device for processing a casting of a large wind driven generator, which comprises a positioning disk, wherein a lightening hole is formed in the center of the positioning disk, reinforcing ribs are arranged in the lightening hole, two ends of each reinforcing rib are fixedly connected with the positioning disk, handles are symmetrically connected to the reinforcing ribs, four hinging bolts are rotationally connected to the positioning disk along the circumferential direction, and vertical drill bushings are connected between adjacent hinging bolts and on the positioning disk. Further, an included angle of 90 degrees is formed between the adjacent hinging bolts, and a first through hole for installing the hinging bolts is formed in the positioning disc. Further, a second through hole for installing the vertical drill bushing is formed in the positioning disc. Further, a circle of protrusions are arranged on the bottom surface of the positioning disc, the inner diameter of each protrusion is the same as the diameter of the corresponding lightening hole, and chamfering is arranged on the outer edge of each protrusion. Further, the positioning plate, the reinforcing ribs and the handle are made of aluminum. Compared with the prior art, the utility model has the beneficial effects that: 1. This quick location perforating device of large-scale aerogenerator casting processing can carry out threaded connection through the bolt hole that the reaming bolt earlier with whole device and aerogenerator casting wheel hub or in the frame when using, then operating personnel only need hand electric drill stretch into the drill bit in the perpendicular drill bushing punch can, has solved traditional marking off and has punched the problem that wastes time and energy. 2. This quick location perforating device of large-scale aerogenerator casting processing, first through-hole and the second through-hole of seting up on the positioning disk are all offered according to the design accuracy in advance, consequently only need fix whole device behind aerogenerator casting wheel hub or frame through the articulated bolt in the first through-hole, later only need the operator use the electric drill in perpendicular drill bushing trompil can, compare traditional marking off punching accuracy higher.
