Abstract
The utility model relates to a lengthened drill bit for a deep-hole drill, which comprises a lengthened rod and a drill bit, wherein one end of the drill bit is sleeved in the lengthened rod and welded with the lengthened rod, the drill bit is drilled with two flutes, a cooling-liquid slot communicated with the drill bit is arranged in the middle of the lengthened rod, and the other end of the lengthened rod is a square handle which is conveniently clamped on a lathe. The lengthened drill bit for the deep-hole drill disclosed by the utility model can be used for safely and reliably drilling a threading deep hole at the center of a main shaft. The structure of a water-turbine generator can also be effectively improved through the easy processing of the deep hole at the center of the main shaft, a current-collecting ring is moved to the end part of the main shaft, and thereby the pollution of powdered carbon is prevented.
Description
Technical field
The utility model relates to a kind of brill flower, and particularly a kind of jumping chisel that adds that is used for depth drill is spent.
Background technology
Present brill flower has a lot of types, wherein when boring alignment of shafts threading deep hole, has danger greatly because bore alignment of shafts threading deep hole, just can't realize maybe will selecting for use on expensive jacking depth drill and the market rare in the past at all.
Summary of the invention
The utility model is finished in order to solve the deficiencies in the prior art, and the purpose of this utility model provides a kind of safe and reliable jumping chisel that adds that bores alignment of shafts threading deep hole and spends.
The utility model is used for the jumping chisel that adds of depth drill to be spent, and comprises extension bar and drill bit, and an end of described drill bit is sleeved in the described extension bar and with described extension bar and welds.
In the utility model, described drill bit offers the twice bit-withdrawing slot, and described extension bar middle part is provided with the cooling liquid bath that is communicated with described drill bit.
In the utility model, the described extension bar other end is for conveniently being installed in the square handle on the lathe.
What the utility model was used for depth drill adds the jumping chisel flower by auxiliary equipment such as high-pressure coolants, can be safe and reliable alignment of shafts threading deep hole be got out, and the appearance of alignment of shafts deep hole can effectively improve the structure of hydrogenerator, collector ring is moved at spindle nose, prevented the pollution of carbon dust.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing 1, the 1---drill bit, the 2---extension bar, the 3---bit-withdrawing slot, 4---cools off liquid bath, 5---side's handle.
The specific embodiment
Be described in further detail below in conjunction with 1 pair of the utility model of accompanying drawing.
A kind of jumping chisel that adds that is used for depth drill of the present utility model is spent, and please refer to correlation diagram among Fig. 1, comprises drill bit 1, extension bar 2.The material of drill bit 1 is a high-speed steel drill, the material of extension bar 2 is modified No. 45 forged steel, and through complete Mechanics Calculation, offer twice bit-withdrawing slot 3 at described drill bit 1, described extension bar 2 middle parts are provided with the cooling liquid bath 4 that is communicated with described drill bit 1, note in the process after boring flower to pierce main shaft 15mm, will withdrawing from, so that move back bits with boring flower.One end of drill bit 1 is inserted in the extension bar 2 and is tight fit, then drill bit 1 and extension bar 2 is welded together and polishes smooth.At the end of extension bar 2 car the long square handle 5 of one section 250mm is arranged, so that drill bit 1 is installed on the lathe.In the process of drilling deep hole, to cool off cutting fluid by high pressure simultaneously and feed in the cooling liquid bath 4, drill bit 1 is constantly cooled off.This novel lengthened brill flower that is used for depth drill is to be applied in to bore in the alignment of shafts threading deep hole, can get out the alignment of shafts threading deep hole of the darkest 2m safely and effectively.What the utility model was used for depth drill adds the jumping chisel flower by auxiliary equipment such as high-pressure coolants, can be safe and reliable alignment of shafts threading deep hole be got out, and the appearance of alignment of shafts threading deep hole can effectively improve the structure of hydrogenerator, collector ring is moved at spindle nose, prevented the pollution of carbon dust.
Above-mentionedly only several concrete enforcement in the utility model is illustrated; but can not be as protection domain of the present utility model; every equivalence of being made according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
