Description

A kind of compressor blade clamping method and the fixture of use

Technical field

The present invention relates to machine adds technical field, particularly to the fixture of a kind of compressor blade clamping method and use.

Background technology

Fig. 1 is a kind of structural representation of the blank of compressor blade, shown in Figure 1, this compressor blade part Blank 1 be forging, it includes tenon portion 11, blade portion 12 and leaf tip 13, follow-up processing in need by several millers Blade portion 12 described in ordered pair carries out the processing of blade type face, after blade type face machines, more described leaf tip 13 is cut Remove, thus forming the blade tip mating with the blade type face in described blade portion 12 (is the institute of this compressor blade part final State the end face in blade portion 12).

Although described tenon portion 11 is clamped easily by the fixture on lathe, due to the described hair of compressor blade Blank 1 is longer, in order to avoid machining deformation it is therefore desirable to carry out positioning clamping to it further that is to say, that to described leaf During line number Milling Machining is entered in body portion 12, need to carry out clamping position, existing folder to the described blank 1 of compressor blade Holding localization method is:First the end face 131 of described leaf tip 13 is carried out levelling, then to described tenon portion 11 using buff wheel After being clamped, (the double tailstock position driving blade processing center of such as five axles) clamping block rubber at the clamping part on lathe Or copper billet, and ensure that rubber or copper block surface are smooth.Then end face 131 and block rubber or the copper block surface of described leaf tip 13 are made Hold out against, adjustment lathe pressure is it is ensured that have larger friction between the described blank 1 of compressor blade and block rubber or copper billet Power.The processing of blade type face can be carried out by blade portion 12 described in number miller ordered pair afterwards.

In the above-mentioned existing course of processing, its essence is the blank 1 by described compressor blade and block rubber or copper Frictional force between block stops the supporting to realize part for moment of torsion during part processing.Frictional force is obvious relative to for the cutting moment of torque Less than normal.Want increasing friction force, by pressure during increase compression, or coefficient of friction realization can be increased.Clamping force increases can be led again Part is caused to be pressed from both sides curved.Simple increase coefficient of friction, effect is also undesirable, and therefore, existing clamping method is easily caused machining deformation Greatly, type face accordance is poor, the problems such as leave blank vestige.For example, block rubber or copper billet be stressed and frictional force effect, table Easily groove in face, and the part now processed easily slips into groove, causes bigger deformation, need to be repaired.Concrete finishing opportunity Cannot accurately judge it is impossible to effectively being managed and controlling.
