Bao Bi the new-style clamping apparatus of turning

08mm. Trial-produce when this spare parts, what we ever used a convention is soft the round means outside 3 ungual clamp, the workpiece when clamp is changeful form, the influence machines precision, in the meantime, because the circle outside semifinished product is irregular, clamp fixed position is not stable, be out of shape to decrease, need to reduce clamping force, but may appear so the circumstance with incompact clip. To this, we break through a tradition accumulate through increasing the interface that hold clip (add seam sleeve) means, used a kind to located at 6 o'clock the float of clamp 3 claw (if pursue 1) , better result was obtained in applying actually. Graph 1 float 3 ungual clamp drift the float that we use the composition of 3 ungual clamping apparatus and working principle 3 ungual clamping apparatus include hammer of 3 ungual noumenon, join piece, clamp to reach special set set. 3 ungual noumenon are through setting a join on join piece, join piece resembles common join with lathe chuck like 3 claw, 6 clamp hammer is secured respectively in couples go up in 3 ungual noumenon, cover in order to set for fulcrum, 3 ungual noumenon follow along with the round discretion outside semifinished product rises and fall, the float that has drop (float momentum has firm demand, cannot give at will) , have float clamp effect. It is certain that clamp nails the pointed department that heads awl to tie semifinished product appearance as the action of clamping force deepness, had not needed large clamping force, can realize Bao Bi the fixed position of treatment and clamp, prevent workpiece to be out of shape. If graph 2a place is shown, to forging because of semifinished product craft is made, on semifinished product many place (B) existence surface caves, common when 3 ungual clamp easy cause workpiece to had been out of shape big or clip is incompact. Use located at 6 o'clock the float of clamp 3 claw can overcome this weakness. Move to the center in chuck in the process, when clamp the hammer is done not have with workpiece B point contact when, 3 ungual noumenon can be covered with setting for the centre of a circle, the spare parts can nail F of an active force to clamp, make 3 ungual noumenon produce certain corner, namely shift of A of clamp hammer sharp drop is nodded to A1, clamp nails a needle to nod B to move to be nodded to B1, if graph 2b place is shown, as 3 claw noumenon clamp movement continues, make hammer of two fixed position expresses surface contact with workpiece at the same time, if graph 2c place is shown, momentum of such 3 ungual noumenal float overcame workpiece surface limitation. Manage together, other two card claw also moves so, sharp drop of 6 clamp hammer is final contact at the same time with the circle outside semifinished product, assured the fixed position clamp of workpiece. Graph principle of 2 float clamp applies the result from mechanical on analysis, traditional 3 ungual interface are the interface of 3 claw and semifinished product to accumulate, set for S1, and located at 6 o'clock the float of clamp the round interface outside 3 ungual clamping apparatus and semifinished product is nodded for two, set for S2, so the intensity of pressure that surface of the spare parts when clamp of two kinds of means gets is P1=F1/S1 and P2=F2/S2 respectively, because S2 is less than S1 far, reason makes sure same intensity of pressure falls, f1 is more than F2 far. Bao Bi in treatment, clamp pressure should Yue Xiaoyue is good, located at 6 o'clock the float of clamp 3 ungual clamping apparatus narrow face getting power nod to two, s2 is very small, at this moment clamp hammer and intensity of pressure of workpiece contact place are greater, make clamp hammer embeds easily workpiece face is particular deepness, clamp relies on attrition strength effect not just, increased the stability of clamp greatly thereby, in clamping force lesser circumstance falls, realized the clamp fixed position of workpiece. In use tradition 3 claw machine 8T-4556 when, workpiece precision assures very hard, fraction defective is taller. This year is much recently, located at 6 o'clock through using the float of clamp 3 ungual clamping apparatus, its machine the effect to be improved apparently, not only satisfied inside the technology measure requirement of aperture, and inside the cylinder of aperture is spent first-rate also. Our preparation extends concept of this one design my company other Bao Bi in treatment. CNC Milling
