Description
Technical field
The utility model relates to the machining tool field, relates in particular to a kind of triangle parallel shank twist drill.
Background technology
In hole drilling and reaming processing, drill bit is the accessory that plays an important role, and is widely used in metal processing.The knife rest inside that is used for the installation drill bit is evenly distributed three projections, and the drillstock of drill bit is generally cylindrical, in high-revolving hole drilling and reaming processing, skidding easily occurs.The model of drill bit and trade mark generally all are engraved on the drillstock, smudgy phenomenon can occur owing to using for a long time, are difficult to distinguish, recognize.Common drill bit uses single, and misoperation can cause the phenomenon that fractures, and affects production efficiency.
The utility model content
The utility model provides a kind of triangle parallel shank twist drill for the prior art above shortcomings, and is rational in infrastructure, in use convenient, flexible, avoided the generation of skidding, be difficult for causing because the phenomenon that fractures that improper use causes has improved production efficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of triangle parallel shank twist drill comprises drillstock, and described drillstock one side is provided with drill neck, and described drill neck one side is provided with drill body, on average is provided with three clamping faces on the described drillstock periphery, and described drillstock cross section is triangle.
Described drill body length is the 40-45 millimeter, and drillstock length is 3 centimetres.
Described drillstock opposite side is provided with drill neck, and described drill neck opposite side is provided with drill body, and the drillstock clamping face is higher than drill neck.
The drillstock clamping face is higher than 1.5 millimeters of drill necks.
Every sidetracking body length is the 20-25 millimeter, and drillstock length is 2 centimetres.
The utility model beneficial effect: rational in infrastructure, convenient and practical, cost is low, is beneficial to popularization, easy operating.
Description of drawings
Fig. 1 is a kind of triangle parallel shank twist drill structural representation described in the utility model.
Fig. 2 is drill bit described in the utility model both sides drill body structural representations.
Among the figure:
The 1-drillstock; The 2-drill neck; The 3-drill body; The 4-clamping face.
The specific embodiment
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings:
As shown in Figure 1, a kind of triangle parallel shank twist drill comprises drillstock 1, and described drillstock 1 one sides are provided with drill neck 2, and described drill neck 2 one sides are provided with drill body 3, on average is provided with three clamping faces 4 on described drillstock 1 periphery, and described drillstock 1 cross section is triangle.Three clamping faces 4 can closely cooperate with knife rest, in high-revolving hole drilling and reaming processing, avoid occurring skidding, and convenient flexible in work is used, drill bit uses lasting.Be the 40-45 millimeter through overtesting drill body length, drillstock length be 3 centimetres the most suitable.Be applicable to the following boring of 40mm, model and the trade mark of drill bit can be engraved on the clamping face simultaneously, the long-time use is difficult for causing the handwriting is blurred phenomenon, is convenient to distinguish, recognize.As shown in Figure 2, as preferred version, described drillstock 1 opposite side also is provided with drill neck 2, and described drill neck 2 opposite sides are provided with drill body 3, drillstock 1 clamping face at middle part is higher than drill neck 2, guaranteed that like this drill bit both sides all can use, saved raw material, improved efficient, in order to guarantee the knife rest drillstock that closely cooperates, therefore drillstock 1 clamping face at middle part will be higher than the drill neck 2 of both sides, can more effectively clamp like this, otherwise can become flexible.It is the most suitable that wherein said drillstock 1 clamping face is higher than 1.5 millimeters of drill necks, the effect of clamping is best, because there is drill body the drill bit both sides, be the 20-25 millimeter through the every sidetracking body length of overtesting, drillstock 1 length at middle part be 2 centimetres the most suitable, be particularly useful for the following boring of 20mm, the drill bit overall dimensions is short, frangibility has not increased service life.
In use, select according to the model of drill bit.This triangle parallel shank twist drill is simple in structure, easy to use, lasting, is convenient for carrying, and has improved production efficiency.
